Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.

The shear wall is inevitably used as an edge member of a building in the structural design of a high-rise residential building, the shear wall made of reinforced concrete needs to be fixed by using the counter-pulling screw rods because of the inner and outer side templates in the conventional construction technology, and the counter-pulling screw rods are usually separated from concrete by using plastic sleeves so as to be convenient for disassembling the mold and taking out the counter-pulling screw rods, and are horizontally arranged. Therefore, the water-close surface outer wall is only based on the grouting of the screw hole and the construction quality of the outer wall waterproof layer, and the screw hole does not have the waterproof function.

Therefore, it is necessary to optimize the traditional formwork system for the shear wall in the near water.

The invention mainly aims to optimize and improve a template system of the water-facing external wall, so that a screw hole on the inner side of a shear wall is always higher than the outer side of the shear wall, and rainwater cannot penetrate into the interior of a building through the screw hole.

The invention is described in further detail below with reference to the figures and specific examples.

Referring to fig. 1 and 3, a schematic view of a first embodiment of the waterproof structure for a screw hole of an outer vertical shear wall according to the present invention is provided, and as shown in the figure, the waterproof structure for a screw hole of an outer vertical shear wall mainly includes a modified novel screw hole of a shear wall, i.e., a tapered hole 11, a tapered sleeve 12 sleeved on a through-wall screw, and a positioning embedded part 13 and a positioning rod 14 for positioning an outer side template 21 on a water-facing side of the shear wall. The purpose of the invention is achieved by reasonably adjusting the shape and the inclination angle of the screw hole of the shear wall and the height difference of the inner wall template and the outer wall template.

The outer contour shape of the tapered sleeve 12 is consistent with the shape of the opening of the tapered hole 11 of the shear wall 20, and the longitudinal length of the tapered sleeve 12 is also consistent with the length of the tapered hole 11, so that after the tapered sleeve 12 is plugged into the tapered hole 11, the two end ports of the tapered sleeve 12 are respectively flush with the two end openings of the tapered hole 11, on one hand, the installation straightness of templates on two sides of the shear wall cannot be influenced, and on the other hand, the tapered sleeve 12 can be conveniently taken out after use.

Preferably, the tapered sleeve 12 is sleeved at the middle section of the wall-through screw 10, and penetrates into the tapered hole 11 of the shear wall along with the wall-through screw 10, two opposite side surfaces of the shear wall 20 respectively form a upstream surface a and a downstream surface b, the tapered hole 11 penetrates through two side surfaces of the upstream surface a and the downstream surface b of the shear wall, the first hole 111 of the tapered hole 11 is arranged on the upstream surface a, the second hole 112 of the tapered hole 11 is arranged on the downstream surface b, and the position of the first hole 111 is always lower than that of the second hole 112, that is, the hole on the upstream surface side is always lower than that on the downstream surface side, so that rainwater cannot flow into the building through the screw hole.

As shown in fig. 3, the positioning embedded part 13 is embedded in the side of the shear wall 20 facing the water surface a, the positioning embedded part 13 is connected with a positioning rod 14, a positioning hole for the positioning rod 14 to insert is formed in the outer side template 21 on the side of the shear wall facing the water surface a, a screw hole for a wall screw to pass through is further formed in the outer side template 21, and the distance between the positioning hole and the screw hole in the outer side template 21 is equal to the distance between the corresponding positioning embedded part 13 and the first opening 111. The use of tapered inserts 13 and locating rods 14 allows precise location of the screw holes in the outer die plate 21. The positioning embedded part 13 adopts a conical embedded part, and the narrow head end of the conical embedded part 13 is positioned on the surface a of the upstream surface of the shear wall. The middle part of the positioning embedded part 13 is provided with a threaded hole, the positioning rod 14 is provided with an external thread matched and screwed with the threaded hole, and the positioning rod 14 is screwed in the threaded hole of the positioning embedded part through the external thread. Clamping or other connecting structures can be adopted between the positioning embedded part 13 and the positioning rod 14. In order to facilitate the positioning, the threaded holes on the positioning embedded parts 13 are generally horizontally arranged, so that the positioning rods 14 can be horizontally arranged.

When the template is installed, the first end of the positioning rod 14 is connected to the positioning embedded part 13, the second end of the positioning rod 14 is screwed with the nut 141 and is matched with the steel pipe 142 and the mountain-shaped clamp 143 for use together, and the outer template 21 is fixed, wherein the middle part of the mountain-shaped clamp 143 is provided with an opening through which the positioning rod 14 passes.

The key technical points of the waterproof structure of the screw hole of the outer vertical face shear wall are as follows: the screw hole on one side of the back water surface on the inner side of the shear wall is always higher than the screw hole on the upstream surface on the outer side, and rainwater is prevented from flowing into the interior of a building from the upstream surface on the outer side from the screw holes. Therefore, it is necessary to ensure that the lower edge of the first hole 111 on the upstream side of the tapered hole 11 is always lower than the lower edge of the second hole 112 on the downstream side.

In the embodiment shown in fig. 1, the inclination of the tapered hole 11 is relatively large, and the lower edge of the second hole 112 is even higher than the upper edge of the first hole 111, at this time, it is necessary to properly adjust the screw hole positions of the wall screws 10 on the outer templates 21 of the inner templates 22 on both sides of the shear wall, and the corresponding screw holes on the templates on both sides are staggered up and down, that is, the screw hole positions of the inner templates 22 are properly adjusted up, or the screw hole positions of the outer templates 22 are properly adjusted down.

For another example, in the embodiment shown in fig. 2, the inclination of the tapered hole 11 is relatively small, and the lower edge of the second hole 112 is slightly higher than the lower edge of the first hole 111 and lower than the upper edge of the first hole 111, at this time, the screw holes on the templates on both sides of the shear wall can still be horizontally aligned without adjusting the height position of the screw holes on the templates on both sides.

The design of the tapered sleeve 12 and the tapered hole 11 can also play a role in eliminating part of construction errors to a certain extent. The technology is also suitable for the construction of a standard layer water-facing shear wall structure, and has higher requirement on the control of the whole construction precision of the template. In addition, the plastic sleeve used in the traditional template system cannot be taken out after the template is removed, the quality effect of the grouting plugging at the later stage of the smooth surface of the inner wall of the plastic sleeve is poor, the conical sleeve can be taken out by tapping due to the special shape of the conical sleeve, and the reutilization property of the conical sleeve effectively responds to the green construction policy.
