Concrete pump pipes are usually used to transport concrete in the construction of high-rise buildings. During the concrete pumping process, the pump pipe will produce greater vibration. At present, the main way to fix the pump pipe on the floor is to use wooden wedges or square timber wedging. The wooden wedge fixing method is mainly to achieve the lateral movement limit of the pump pipe, and has little effect on the longitudinal movement limit of the pump pipe. At the same time, it cannot reduce the damage caused by the vibration of the pump pipe to the floor structure; the square timber wedging method is cumbersome to operate and is not conducive to the reuse of square timber. In pumping concrete, after the pump pipe is fixed by wooden wedges, if the lower pump pipe needs to be removed due to pipe blockage, the upper pump pipe may slide freely, posing a safety hazard.

[0015] The following will be combined with specific embodiments and attached Figure 1-3 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0016] The utility model provides a concrete pump pipe through the floor fixing device (such as Figure 1 As shown), it includes a clamping seat 1, a buffer layer 2, and a lower clamping member 3. The clamping seat 1 includes two symmetrically arranged clamping fasteners, each of which includes a semicircular tube 11, a supporting plate 12 is fixedly arranged on the upper rear side of the semicircular tube 11, and a docking ear 13 is respectively arranged on the left and right sides of the semicircular tube 11. In actual application, the semicircular tube 11, the supporting plate 12 and the docking ear 13 are all made of steel plates welded and processed, and the corresponding docking ears 13 on the two semicircular tubes 11 are fixedly connected by bolt connection. Specifically, two through holes 131 are arranged on the docking ear 13, and the screws are screwed in place. After the bolt is passed through the two corresponding through holes 131, the nut on the bolt is tightened to achieve the fixed connection of the two docking ears 13, and then the docking clamping of the upper parts of the two semicircular tubes 11 can be achieved. When the two semicircular tubes 11 are docked to form a circular tube, the outer wall of the circular tube fits with the inner wall of the pump pipe through hole set on the floor 5, that is, the outer diameter of the formed circular tube is adapted to the inner diameter of the pump pipe through hole. A buffer layer 2 is provided on the inner wall of each of the semicircular tubes 11. In this specific embodiment, the buffer layer 2 can be a rubber sheet. The rubber sheet has a certain elasticity. When the two semicircular tubes 11 are used to press the rubber sheet against the top After being put on the pump pipe 4, the rubber sheet is compressed, thereby achieving effective clamping of the pump pipe 4. At the same time, when the pump pipe 4 vibrates, the rubber sheet has a certain vibration absorption function, thereby reducing the influence of the vibration of the pump pipe 4 on the floor structure. The rubber sheet is compressed and the side wall of the circular tube fits with the side wall of the pump pipe through hole, so that there is no moving gap between the side wall of the pump pipe 4 and the side wall of the pump pipe through hole, and then when the pump pipe 4 moves laterally, the lateral movement of the pump pipe 4 is limited; the lower clamping member 3 is used to clamp and fix the lower part of the two semicircular tubes 11 after docking. The upper parts of the two semicircular tubes 11 are docked and clamped by docking ear plates 13, and the lower parts are The lower clamping member 3 is used to achieve docking clamping, so that the upper and lower parts of the semicircular tube 11 can effectively clamp and fix the pump tube 4. When the clamping base 1 is placed in the through hole of the pump tube 4, the lower clamping member 3 can prevent the clamping base 1 from moving upward, that is, when the pump tube 4 is fixed on the floor slab by using this device, the size of the lower clamping member 3 is larger than the diameter of the pump tube through hole on the floor slab. Therefore, during the upward movement of the pump tube 4, the lower clamping member 3 is blocked by the floor slab 5, thereby realizing the upward movement of the pump tube 4. Furthermore, during the downward movement of the pump tube 4, the support plate 12 is clamped on the upper plane of the floor slab 5, thereby realizing the downward movement limit of the pump tube 4.
[0017] In the above embodiment, the specific implementation of the lower clamping member 3 is as follows: the lower clamping member 3 includes two arc-shaped clamping plates 31, and the two ends of the two arc-shaped clamping plates 31 are fixedly connected by bolt connection. Specifically, a connecting lug 311 is fixedly arranged on both sides of each arc-shaped clamping plate 31, and a through hole for the bolt to penetrate is arranged on the connecting lug 311. When the two arc-shaped clamping plates 31 are docked, the bolt is penetrated into the through hole of the two connecting lugs 311, and then the nut on the bolt is tightened to achieve docking and clamping of the arc-shaped clamping plates 31. Further, in order to improve the stable limit of the arc-shaped clamping plate 31 at the lower part of the semicircular tube 11, an arc-shaped slot 111 for achieving the clamping limit of the arc-shaped clamping plate 31 is arranged on the outer side of the lower part of the semicircular tube 11. When installing the arc-shaped clamping plate 31, the arc-shaped clamping plate 31 is first clamped in the arc-shaped slot 111, and then the docking and clamping operation of the two arc-shaped clamping plates 31 is performed.
[0018] When the present device is used to clamp and fix the pump tube 4, the pump tube 4 can be first passed through the pump tube through hole pre-opened on the floor 5. After the pump tube is passed through, the two clamping fasteners are first inserted into the pump tube through hole. Then, after the semicircular tube 11 is inserted into place, the two corresponding docking ears 13 are fixed and clamped by bolts, and then the upper part of the two semicircular tubes 12 is clamped on the pump tube 4. Then, the two arc-shaped clamping plates 31 are correspondingly placed in the arc-shaped clamping grooves 111. Then, the two corresponding connecting ear plates 311 are fixed and clamped by bolts, and then the lower part of the two semicircular tubes 12 is clamped on the pump tube 4, and finally the present device clamps and fixes the pump tube 4 on the floor.
[0019] In the present invention, "upper" and "lower" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.
[0020] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
[0021] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the utility model, but the utility model is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
