As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, a continuous-engagement steel pipe concrete shear wall 10 includes a steel pipe unit 100 and an arc-shaped steel box unit 200, wherein the steel pipe unit 100 is a hollow cylindrical structure, and concrete is poured into the steel pipe unit 100; the arc-shaped steel box unit 200 is defined by two stress side walls 210 and two occlusion side walls 220 together, the two stress side walls 210 are arranged oppositely, the two stress side walls 210 are both in arc surface structures, the two stress side walls 210 are protruded towards the direction far away from the center of the arc-shaped steel box unit 200, the two occlusion side walls 220 are arranged oppositely, the two occlusion side walls 220 are both in arc surface structures, the two occlusion side walls 220 are protruded towards the direction close to the center of the arc-shaped steel box unit 200, and concrete is poured into the arc-shaped steel box unit 200; the side surface of the steel pipe unit 100 is fixedly connected to the bite side wall 220.

It should be noted that the steel pipe unit 100 may be made of a common metal material, or may be made of a concrete pipe, the arc-shaped steel box unit 200 may be enclosed by four surfaces, i.e., two stress sidewalls 210 and two engagement sidewalls 220, the two stress sidewalls 210 are disposed opposite to each other, the two engagement sidewalls 220 are disposed opposite to each other, two ends of each stress sidewall 210 are connected to the two engagement sidewalls 220, and two ends of each engagement sidewall 220 are connected to the two stress sidewalls 210, so that the arc-shaped steel box unit 200 is enclosed by the two stress sidewalls 210 and the two engagement sidewalls 220. The two stress side walls 210 are protruded towards the direction far away from the center of the arc-shaped steel box unit 200, so that when the arc-shaped steel box unit 200 bears the load perpendicular to the stress side walls 210, the arc-shaped stress side walls 210 can bear larger load compared with the conventional straight plate structure, and under the condition of bearing the same load, the thickness of the continuous meshing steel pipe concrete shear wall 10 is thinner than that of the conventional shear wall, so that the purpose of saving space is achieved.

Both the engagement sidewalls 220 are protruded toward the center of the arc-shaped steel box unit 200, so that the engagement sidewalls 220 can be better connected with the steel pipe unit 100, and the side surfaces of the steel pipe unit 100 and the engagement sidewalls 220 can be connected by welding or bolting. Because the arc-shaped steel box units 200 are provided with the two engagement side walls 220, a plurality of arc-shaped steel box units 200 and the steel pipe units 100 can be fixedly connected in sequence, so that the complete continuous engagement steel pipe concrete shear wall 10 is formed.

And because the steel pipe unit 100 is a cylindrical structure, and the two engagement side walls 220 of the arc-shaped steel box unit 200 are both protruded towards the direction close to the center of the arc-shaped steel box unit 200, the arc-shaped steel box unit 200 can be connected with any part of the circumference of the outer side wall of the steel pipe unit 100, and when a plurality of arc-shaped steel box units 200 are sequentially and fixedly connected with the steel pipe unit 100, the continuous engagement steel pipe concrete shear wall 10 can be connected into an arc shape with any radian according to actual needs by adjusting the connection part and angle of the steel pipe unit 100 and the arc-shaped steel box unit 200, in particular in the design of some artistic venues, the adoption of the continuous engagement steel pipe concrete shear wall 10 in the scheme can conveniently construct the shear wall into the arc shape, and because the arc-shaped steel box units 200 are continuously engaged and arranged with the steel pipe units 100, the arc-shaped shear wall is not.

In practical use, the steel pipe unit 100 and the arc-shaped steel box unit 200 are usually connected by welding, but the firmness of the welding connection depends greatly on the operation quality of a welder, and a welded seam is also easily damaged, so that when the continuous engaged steel pipe concrete shear wall 10 is vibrated, the steel pipe unit 100 is easily separated from the arc-shaped steel box unit 200, which causes a safety hazard. Based on this, the invention also designs a prestress locking mechanism 300 for fixing the steel pipe unit 100 and the arc-shaped steel box unit 200.

Referring to fig. 3, in one embodiment, the continuous-engagement steel tube concrete shear wall 10 further includes a prestressed locking mechanism 300, the prestressed locking mechanism 300 includes a first locking member 310 and a second locking member 320, one end of the first locking member 310 is provided with a first protrusion 311, the other end of the first locking member 310 is provided with a threaded portion 312, one end of the second locking member 320 is provided with a second protrusion 321, the other end of the second locking member 320 is provided with a threaded hole 322, two engagement side walls 220 of the arc-shaped steel box unit 200 are respectively provided with a first locking hole 221 and a second locking hole 222, the side walls of the steel tube unit 100 are provided with a locking through hole 110, one end of the first locking member 310 provided with the threaded portion 312 sequentially passes through the locking through hole 110 and the first locking hole 221 and enters the inside of the arc-shaped steel box unit 200, the first protrusion 311 is used for abutting against the inner side wall of the steel tube unit 100, and one end of the second locking member 320 provided with the threaded hole 322 sequentially passes In the steel box unit 200, the second lug 321 is abutted against the inner side wall of the steel pipe unit 100, and the thread part 312 is screwed with the thread hole 322;

it should be noted that, the left and right sides of the arc-shaped steel box unit 200 are connected to one steel pipe unit 100, when installing, the first locking member 310 is first placed into the left steel pipe unit 100, one end of the threaded portion 312 of the first locking member 310 is aligned with the locking through hole 110, then the first locking member 310 is pushed such that one end of the threaded portion 312 sequentially passes through the locking through hole 110 and the first locking hole 221 and enters the inside of the arc-shaped steel box unit 200, similarly, the second locking member 320 is placed into the right steel pipe unit 100, one end of the threaded hole 322 of the second locking member 320 is aligned with the locking through hole 110, then the second locking member 320 is pushed such that one end of the threaded hole 322 sequentially passes through the locking through hole 110 and the second locking hole 222 and enters the inside of the arc-shaped steel box unit 200, and the first protrusion 311 and the second protrusion 321 are both larger than the locking through hole 110, thus, as the threaded, the distance between the first projection 311 and the second projection 321 is gradually reduced, so that the two steel pipe units 100 on the left and right sides of the arc-shaped steel box unit 200 are tightly attached to the arc-shaped steel box unit 200, and thus, when the steel pipe concrete shear wall 10 is continuously engaged and vibrated, the steel pipe units 100 are not easily separated from the arc-shaped steel box unit 200, and the safety is improved.

When the prestressed locking mechanism 300 is used, the threaded portion 312 is normally screwed into the threaded hole 322 until the first projection 311 abuts against the inner wall of the steel pipe unit 100 and the second projection 321 abuts against the inner wall of the steel pipe unit 100.

However, if the screw part 312 is continuously twisted after the first projection 311 abuts against the inner wall of the steel pipe unit 100 and the second projection 321 abuts against the inner wall of the steel pipe unit 100, so that the screw part 312 is continuously screwed into the screw hole 322, the curved steel box unit 200 is pre-stressed by the pre-stressed locking mechanism 300 to the two engaging sidewalls 220, while the two curved stress sidewalls 210 of the curved steel box unit 200 will bulge more outwardly in the event of compression of the curved steel box unit 200, therefore, the compressive capacity of the arc-shaped steel box unit 200 when the arc-shaped steel box unit 200 is used for dealing with the load perpendicular to the stress side wall 210 is improved, that is, the prestress locking mechanism 300 improves the connection firmness of the arc-shaped steel box unit 200 and the steel pipe unit 100 and also improves the capacity of the arc-shaped steel box unit 200 for bearing the transverse load, thereby improving the integral firmness of the continuous engagement steel pipe concrete shear wall 10.

It should be noted that, when the first locking member 310 is connected with the second locking member 320, the first locking member 310 or the second locking member 320 needs to be fixed during the process of screwing the threaded portion 312 into the threaded hole 322 so as to screw the threaded portion 312 into the threaded hole 322, but the narrow internal space of the arc-shaped steel box unit 200 is inconvenient for the fixing operation of the first locking member 310 or the second locking member 320, and after the first locking member 310 is screwed with the second locking member 320, when the continuous engagement steel pipe concrete shear wall 10 is vibrated, the first locking member 310 and the second locking member 320 may rotate relatively, which results in the loosening failure of the pre-stressed locking mechanism 300.

In order to solve the problem, the anti-loosening reinforcing rib plate 400 and the two anti-skidding limiting columns 500 are further arranged, the anti-loosening reinforcing rib plate 400 is provided with a strip-shaped groove 410, the cross section of one end, provided with the threaded hole 322, of the second locking piece 320 is square, and the strip-shaped groove 410 is used for being clamped with one end, provided with the threaded hole 322, of the second locking piece 320. Before the anti-loosening reinforcing rib plate 400 is installed, the first locking member 310 and the second locking member 320 are connected nearly, then, one end of the anti-loosening reinforcing rib plate 400, which is provided with the strip-shaped groove 410, is inserted into the arc-shaped steel box unit 200 downwards, and because the cross-sectional shape of one end of the second locking member 320, which is provided with the threaded hole 322, is square, the end of the second locking member 320, which is provided with the threaded hole 322, is clamped with the strip-shaped groove 410 after the anti-loosening reinforcing rib plate 400 is inserted, so that the second locking member 320 is prevented from rotating inside the arc-shaped steel.

In order to facilitate the installation and fixation of the anti-loose reinforcing rib plate 400, the anti-skid limiting surfaces 420 are respectively arranged on two side surfaces of the anti-loose reinforcing rib plate 400 close to the two stress side walls 210, the anti-skid limiting surfaces 420 are arc-shaped surfaces, and the anti-skid limiting surfaces 420 are recessed in the direction far away from the stress side walls 210, so that a certain space is left between the anti-skid limiting surfaces 420 and the stress side walls 210 to facilitate the installation of the anti-loose reinforcing rib plate 400, after the anti-skid limiting columns 500 are installed, the anti-skid limiting columns 500 are plugged between the anti-skid limiting surfaces 420 and the stress side walls 210, the anti-skid limiting columns 500 are designed into an elliptical column structure to prevent the anti-skid limiting columns 500 from rolling between the anti-skid limiting surfaces 420 and the stress side walls 210, and therefore, the anti.

When concrete is poured into the arc-shaped steel box unit 200 provided with the anti-loosening reinforcing rib plate 400, the anti-loosening reinforcing rib plate 400 divides the arc-shaped steel box unit 200 into two spaces, so that the concrete is not smooth to flow, concrete is usually required to be poured into two sides of the anti-loosening reinforcing rib plate 400 in the arc-shaped steel box unit 200 simultaneously during construction, and the construction difficulty is increased.

It can be understood that the radius of the steel pipe unit 100 is equal to the radius of the engagement sidewall 220, so that the steel pipe unit 100 can be completely attached to the engagement sidewall 220 when abutting against the engagement sidewall 220, thereby improving the connection effect between the steel pipe unit 100 and the arc-shaped steel box unit 200.

Referring to fig. 1, in one embodiment, the steel pipe unit 100 is provided with longitudinal reinforcing ribs 120 inside, the longitudinal reinforcing ribs 120 in the steel pipe unit 100 are provided with six longitudinal reinforcing ribs 120, and the six longitudinal reinforcing ribs 120 are uniformly distributed on the inner side wall of the steel pipe unit 100. It can be understood that the longitudinal reinforcing ribs 120 arranged inside the steel tube unit 100 can improve the structural strength of the steel tube unit 100 and improve the load bearing capacity of the continuously engaged steel tube concrete shear wall 10.

When the continuous-engagement steel pipe concrete shear wall 10 is provided with the prestress locking mechanism 300, the first locking member 310 and the second locking member 320 are connected through threads, the first locking member 310 is screwed relative to the second locking member 320 so that the threaded portion 312 is gradually screwed into the threaded hole 322, and in order to provide sufficient pretightening force, the first locking member 310 and the second locking member 320 need to be screwed relatively, but the space inside the steel pipe unit 100 and the space inside the arc-shaped steel box unit 200 are narrow, so that an operator cannot conveniently extend tools such as a wrench into the steel pipe unit 100 or the arc-shaped steel box unit 200 to screw the steel pipe unit, and even if the tools are extended and screwed by small tools, the requirement on the sufficient pretightening force is difficult to achieve.

Therefore, the invention also provides a tooth-shaped screwing mechanism.

The tooth-shaped screwing mechanism comprises a first rack, the first lug is of a gear structure, the first rack is vertically arranged on the inner side wall of the steel pipe unit in a sliding mode, the first rack is abutted to the first lug, and the first rack is used for driving the first lug to rotate.

The tooth-shaped screwing mechanism further comprises a second rack, the second rack is vertically arranged on the inner side wall of the steel pipe unit in a sliding mode, the second rack is abutted to one side, away from the first rack, of the first lug, and the second rack is used for driving the first lug to rotate.

Referring to fig. 3 and 5, it can be understood that the first rack 710 can be connected to the inner sidewall of the steel pipe unit 100 through a guide rail, so that the first rack 710 can vertically slide on the inner sidewall of the steel pipe unit 100, and the first rack 710 abuts against the first protrusion 311, so that when the first rack 710 vertically slides on the inner sidewall of the steel pipe unit 100, the first protrusion 311 is driven by the first rack 710 to perform a rotational motion, that is, the first locking member 310 is driven by the first rack 710 to perform a rotational motion, so that the first locking member 310 can be rotated by driving the first rack 710 to move up and down, thereby easily and conveniently realizing the tightening operation of the first locking member 310 and the second locking member 320.

The single first rack 710 still requires labor when driving the first protrusion 311, so the second rack 720 is additionally arranged in the steel pipe unit 100, and the second rack 720 and the first protrusion 311 are abutted against one side of the first rack 710, so when screwing the first protrusion 311, only the first rack 710 and the second rack 720 need to be driven to move simultaneously, and the first rack 710 and the second rack 720 move close to each other or move away from each other, so the first protrusion 311 is pushed by the first rack 710 and the second rack 720 simultaneously, so that the rotation of the first protrusion is smoother, and the first locking member 310 and the second locking member 320 can be screwed more tightly, that is, the prestress applied by the prestress locking mechanism 300 on the arc-shaped steel box unit 200 is larger.

In one embodiment, the curved steel box unit 200 may be a fish-curved shape, the thicknesses of the steel pipe unit 100 and the curved steel box unit 200 are determined by calculation according to the actual bearing forces to which the steel pipe unit 100 and the curved steel box unit 200 are subjected, the steel pipe unit 100 and the curved steel box unit 200 are assembled on site after being manufactured in a factory, and concrete is poured into the steel pipe unit 100 and the curved steel box unit 200 after the steel pipe unit 100 and the curved steel box unit 200 are assembled end to end. Under the condition that the requirement on strength is low, the steel pipe unit 100 and the arc-shaped steel box unit 200 can be directly spliced together, and the welding operation is omitted.

The continuous-occlusion steel pipe concrete shear wall 10 is formed in a factory and assembled on site, the on-site welding workload is less, no steel bar binding or template manufacturing is needed, the construction is convenient and efficient, the strength is high, and the section is small.

Compared with the prior art, the invention has at least the following advantages:

1. according to the continuous-meshing steel pipe concrete shear wall 10, the steel pipe units 100 and the arc-shaped steel box units 200 are arranged, and the steel pipe units 100 and the arc-shaped steel box units 200 are connected with each other to form the shear wall together, so that the thickness of the shear wall is reduced to improve the space utilization rate, the strength is improved to provide better earthquake resistance, and the part with larger curvature of the arc-shaped shear wall can be prevented from cracking or being damaged when the arc-shaped shear wall with curvature is built.

2. In addition to the prestress locking mechanism 300 which is arranged in the continuous-engagement steel pipe concrete shear wall 10 enables the connection between the steel pipe unit 100 and the arc-shaped steel box unit 200 to be tighter and prevents the steel pipe unit 100 from being separated from the arc-shaped steel box unit 200, the prestress locking mechanism 300 exerts prestress on the arc-shaped steel box unit 200 during locking, so that the stress side wall 210 of the arc-shaped steel box unit 200 can bear larger load, and the anti-seismic and stabilizing effects of the continuous-engagement steel pipe concrete shear wall 10 are improved.

3. According to the continuous-meshing steel pipe concrete shear wall 10, the damping and cushioning mechanism 600 is arranged, so that when the continuous-meshing steel pipe concrete shear wall 10 is subjected to strong vibration, the damping and cushioning mechanism 600 supports the continuous-meshing steel pipe concrete shear wall 10, the deformation degree of the continuous-meshing steel pipe concrete shear wall 10 is reduced, and partial load borne by the continuous-meshing steel pipe concrete shear wall 10 is absorbed, so that the deformation amount of the continuous-meshing steel pipe concrete shear wall 10 after the strong vibration is reduced, and the overall safety of a building is improved.
