Technical Field

The invention belongs to the field of existing building construction, and particularly relates to a stepping building translation method.

Background

Along with the acceleration of the urbanization process and the continuous expansion of the urban scale, roads in main urban areas need to be widened and modified, a large number of buildings with good performance are removed too early, and great resource waste is caused. In the traditional translation or rotation of a building (a large member), a method of jacking or pulling by a jack is mostly adopted, generally, a lower translation rail needs to be made along the translation direction, so that the translation building can be moved or rotated to a new site on the lower translation rail, if the translation distance is long, the required lower rail road line is naturally long, and the lower translation rail is completely dismantled after translation, so that considerable resource waste is caused.

Patent CN101962998B stepping self-walking building shifting device discloses a stepping shifting method, which comprises an upper slide block, a lower slide block, and a vertical jack and a bidirectional horizontal jack which are arranged together. The upper sliding block is contacted with the bottom of the mobile building, the lower sliding block is contacted with the ground, and the mobile sliding surface is positioned between the upper sliding block and the lower sliding block. Within a horizontal step length range, a vertical jack of the device provides supporting force, and meanwhile, a horizontal bidirectional jack positioned on the lower sliding body pushes the upper sliding body to enable the building and the upper sliding body to slide together in a preset direction, and at the moment, a lower sliding block of the device does not slide relative to the ground. Two groups of the devices move mutually, and when one group works, the other group is in a suspension state, so that the stepping of the building is realized. This step-by-step shifting method also has its drawbacks: 1. the building has heavy weight, even if the friction coefficient of the moving sliding surface is small, the friction force is also large, the required horizontal thrust is large, and the lower sliding block can slide with the ground in the process of pushing the building to move forwards. 2. The structure is more complicated, and existing horizontal two-way jack and vertical jack between last slider and the lower slider cause the mechanism more complicated, and installation and maintenance are troublesome. Because the pressure is bigger in the workplace, the equipment is easy to damage, and once damaged, the maintenance is troublesome. There is a need for a method of building translation that is simple to operate and low in cost.

Detailed Description

As shown in fig. 1-5, a stepping building translation device comprises a underpinning beam 3 fixed with a building, a supporting raft 8 and a translating raft 6 are arranged below the underpinning beam 3, a first telescopic driving mechanism 7 which is telescopic up and down is arranged between the supporting raft 8 and the underpinning beam 3, two second telescopic driving mechanisms 5 which are arranged front and back in the moving direction of the building are arranged between the translating raft 6 and the underpinning beam 3, and two ends of the second telescopic driving mechanisms 5 are respectively hinged with the underpinning beam 3 and the translating raft 6. The second telescopic driving mechanisms 5 are obliquely arranged with the ground in the advancing direction of the building, and the oblique directions of the two second telescopic driving mechanisms 5 are opposite; the two second telescopic driving mechanisms 5, the underpinning beam 3 and the translational raft 6 are connected to form a four-bar structure. The translational rafts 6 and the support rafts 8 may be prefabricated components. Because of the gravity of the building, if the two second telescopic driving mechanisms 5 incline in the same direction, the four-bar linkage mechanism is forced to rotate, so that the support is unstable. Under the condition that the inclination directions of the two second telescopic driving mechanisms 5 are opposite, the four-bar mechanism is offset by the moment, and is not easy to rotate due to gravity, so that the four-bar mechanism formed in such a way is relatively stable. The upper and lower sides of the four-bar linkage are not equal in length. Because the underpinning beam 3 is relatively long, the upper side length and the lower side are preferred. The upper side length of the four-bar linkage is here the distance between the second telescopic drive 5 and the two hinge points of the building. The lower length is the distance between the two hinge points of the second telescopic drive mechanism 5 and the translational raft 6. Under the operating condition, after the first telescopic driving mechanisms 7 extend to enable the supporting rafts 8 to compress and support the building with the ground, the front and the back second telescopic driving mechanisms 5 extend one by one or shorten one by one, and the translation rafts 6 translate one step under the condition that the building is integrally immobile. The first telescopic drive mechanism 7 is then retracted to the point where the support rafts 8 are in a suspended condition. At the moment, the translation raft 8 plays a supporting role, and the front and the back second telescopic driving mechanisms 5 extend or shorten one by one to enable the building to move forward by one step under the condition that the translation raft 6 does not move. And cycling until the move is complete. This stepping method does not require a track. And simple structure, operate steadily, be difficult to break down, the cost is lower.

The underpinning beams 3 are at least two, and at least one supporting raft 8 and at least one translating raft 6 are arranged below each underpinning beam 3. In this embodiment, two underpinning beams 3 are arranged in parallel. A translation raft 6 is arranged below each underpinning beam 3, and a supporting raft 8 is arranged at the front and the rear of the translation raft 6.

Each of two sides of the underpinning beam 3 is respectively hinged with two second telescopic driving mechanisms 5 which are arranged in the front and back direction of the building moving direction. The second telescopic driving mechanisms 5 at two sides of the underpinning beam 3 are symmetrically arranged. Thus, the translation device is more supported and more stable. Preferably the lower ends of the four second telescopic drive mechanisms 5 are arranged on the same translating raft 6.

A horizontal steel cross beam 4 is arranged on the underpinning beam 3, and two ends of the steel cross beam 4 extend out of two sides of the underpinning beam 3; one end of a second telescopic driving mechanism 5 at two sides of the underpinning beam 3 is respectively hinged with a transverse steel beam 4 at the same side and is arranged on the underpinning beam 3 through the transverse steel beam 4.

The underpinning beams 3 are arranged in parallel with the ground, are arranged on two sides of the frame column 1 of the building and are fixed with the frame column 1. The underpinning beam 3 can wrap the frame column 1 from two sides in the construction process. One underpinning beam 3 can be connected to several frame columns 1 on the same side. The first telescopic driving mechanism 7 and the second telescopic driving mechanism 5 are jacks. And a hydraulic jack is preferably selected, so that the operation is convenient.

A chain 9 is arranged between the supporting raft 8 and the underpinning beam 3. The supporting rafts 8 can be hung on the underpinning beam 3 through chains 9. One end of the first telescopic driving mechanism 7 is fixed on the supporting raft 8, and the other end is not connected with the building. When the second telescopic driving mechanism 5 is in a jacking state, the supporting raft 8 is lifted and suspended through the chain 9, and the supporting raft leaves the ground and moves along with the building. When the second telescopic driving mechanism 7 is in a contraction state, the support raft 8 automatically falls down, and the chain is in a relaxed free falling state. The bottom of the underpinning beam 3 is contacted with a first telescopic driving mechanism 7, and the first telescopic driving mechanism 7 jacks and supports the upper building. The second telescopic drive mechanism 5 starts to move the translational raft 6 one stroke forward.

A stepping building translation method comprises the following steps: the method comprises the following steps: (1) constructing underpinning beams 3 on two sides of a building frame column 1, wherein the underpinning beams 3 are fixedly connected with the frame column 1; (2) excavating a soil layer at the lower part of the ground beam, and arranging supporting rafts 8 in the excavated space; a first telescopic driving mechanism 7 which is telescopic up and down is arranged between the supporting raft 5 and the underpinning beam 3; (3) jacking the building by using a first telescopic driving mechanism 7, cutting the frame column 1 below the ground beam 2, and separating the translation building from the original foundation; (4) arranging a translation raft 6 in the excavated space, arranging two second telescopic driving mechanisms 5 arranged front and back in the moving direction of the building between the translation raft 6 and the underpinning beam 3, and respectively hinging the underpinning beam 3 and the translation raft 6 at two ends of each second telescopic driving mechanism 5; the second telescopic driving mechanisms 5 are obliquely arranged with the ground in the advancing direction of the building, and the oblique directions of the two second telescopic driving mechanisms 5 are opposite; the two second telescopic driving mechanisms 5, the underpinning beam 3 and the translational raft 6 are connected to form a four-bar structure; (5) the second telescopic driving mechanism 5 is started to enable the translational raft 6 to move forwards for a certain distance and then to be firmly supported; the first telescopic driving mechanism 7 is pulled back to separate the supporting raft 8 from the foundation 10, and the second telescopic driving mechanism 5 is started again to enable the building to move forwards for a certain distance; jacking up the first telescopic mechanism 7 to enable the supporting raft 8 and the foundation 10 to be firmly pressed, and re-supporting the translated building on the supporting raft 8; (6) and (5) repeating the step (5) until the preset position is reached.

And after the building is translated in place, connecting and anchoring the frame columns 1 with a new site, dismantling the underpinning beam 3, dismounting the first telescopic driving mechanism 7 and the second telescopic driving mechanism 5, moving out the translation raft 6 and the support raft 8, and completing the construction of the building translation project.
