Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a tool for sealing a pipe pile core cage and an inner wall of a pipe pile. Background Art
[0002] In the construction of prefabricated pipe pile core cages, concrete slurry accumulates in the inner wall of the pipe pile during the processing of the pipe pile, and is unevenly accumulated. As a result, when processing the pile core cage, the thickness of the concrete slurry on the inner wall must be considered, and the support plate often needs to be processed smaller to ensure that the pile core cage can fit the pipe pile. In this way, when pouring concrete, due to the existence of gaps and the high fluidity of the concrete in the pile core cage, coupled with the fact that the concrete is mixed with small-diameter gravel, when pouring the pile core, the concrete often leaks into the pile along the gaps, resulting in a large amount of concrete waste. The leakage will also cause the bottom of the pile core to become loose, greatly affecting the construction quality. Utility Model Content
[0003] The utility model aims to provide a tool for sealing the core cage of a pipe pile and the inner wall of the pipe pile, which can ensure that the core cage can be smoothly placed in the pipe pile and at the same time seal the gap between the support plate and the pipe pile, effectively intercepting concrete, avoiding waste due to leakage of concrete and the loose bottom of the pile core, ensuring construction quality, and having a simple structure and easy use.
[0004] The utility model adopts the following technical solutions:
[0005] A tool for sealing a pipe pile core cage and an inner wall of a pipe pile, comprising a support plate, on which a bottom support is arranged, wherein the size of the bottom support is larger than the size of the support plate, and the peripheral edge of the bottom support extends from the outer edge of the support plate; in addition, the strength of the bottom support is smaller than the strength of the support plate, and the portion of the bottom support extending from the outer edge of the support plate can be deformed upward to form a structure that encloses the support plate.
[0006] Preferably, the base is arranged at the bottom of the support plate.
[0007] Preferably, the base support and the support plate are both disc-shaped structures, and the base support and the support plate are coaxially arranged.
[0008] Preferably, the base is a mesh structure.
[0009] Preferably, the base includes a support net arranged below the support plate, and an isolation net is arranged below the support net, wherein the aperture of the support net is larger than the aperture of the isolation net.
[0010] Preferably, a reinforcement plate is provided at the bottom of the isolation net.
[0011] Preferably, the reinforcement plate is connected to the support net, the isolation net and the support plate by bolts.

[0014] Preferably, the sum of the length of the support rod and the radius of the reinforcement plate is smaller than the radius of the isolation net.
[0015] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and is easy to use. It can seal the gap between the support plate and the pipe pile while ensuring that the pile core cage can be smoothly placed in the pipe pile, effectively intercepting the concrete, avoiding the waste caused by leakage of concrete and the loose bottom of the pile core, thereby ensuring the construction quality; specifically, by arranging a large-sized bottom support on the support plate, the friction between the bottom support and the inner wall of the pipe pile when the pile core cage is lowered is used to realize the upward deformation and folding of the part of the bottom support protruding from the edge of the support plate, thereby achieving the sealing of the gap between the inner wall of the pipe pile and the support plate, and retaining the concrete, reducing the waste of concrete caused by leakage, and at the same time avoiding the problem of loose bottom of the pile core, thereby ensuring the construction quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 This is a schematic diagram of the structure of an embodiment of the present application;
[0017] Figure 2 It is a cross-sectional view of an embodiment of the present application. DETAILED DESCRIPTION
[0018] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:
[0019] like Figure 1 to Figure 2 As shown, a tool for sealing a pipe pile core cage and an inner wall of a pipe pile described in the utility model comprises a support plate 1, on which a bottom support 2 is arranged, the bottom support 2 and the support plate 1 are both disc-shaped structures, and the bottom support 2 is coaxially arranged with the support plate 1; wherein the size of the bottom support 2 is larger than that of the support plate 1, and the peripheral edge of the bottom support 2 extends from the outer edge of the support plate 1 to make up for the gap between the inner wall of the pipe pile and the support plate 1, so as to avoid leakage of concrete; in addition, the strength of the bottom support 2 is smaller than that of the support plate 1, so that the part of the bottom support 2 extending from the outer edge of the support plate 1 can be deformed upward under the action of friction with the inner wall of the pipe pile, forming a structure enclosing the support plate 1, which can not only closely abut against the inner wall of the pipe pile, sealing the gap between the support plate 1 and the inner wall of the pipe pile, but also intercepting the concrete, avoiding the leakage and waste of concrete and the problem of looseness at the bottom of the pile core.
[0020] Among them, in this embodiment, the bottom support 2 is arranged at the bottom of the support plate 1; so that when the pile core cage is lowered, after the bottom of the bottom support 2 is subjected to force, only the part protruding from the edge of the support plate 1 is deformed upward, thereby avoiding the situation where the bottom support 2 is arranged above the support plate 1 due to excessive friction, which causes the overall deformation of the bottom support 2, and ensures the close contact between the bottom support 2 and the inner wall of the pipe pile; in addition, the bottom support 2 is a mesh structure, which can not only reduce its structural strength, ensure the smooth lowering of the pile core cage, but also achieve the retention of concrete; specifically, the bottom support 2 includes a support net 2-1 arranged below the support plate 1, and an isolation net 2-2 is arranged at the lower part of the support net 2-1, wherein the aperture of the support net 2-1 is larger than the aperture of the isolation net 2-2; the support net 2-1 has a large mesh and a coarse mesh diameter for providing support, and the isolation net 2-2 has a dense mesh and a small mesh diameter for retaining concrete; the support net 2-1 is arranged on the top, and the isolation net 2-2 is arranged on the bottom, which can reduce the impact of concrete on the isolation net 2-2 and ensure its retention effect on concrete. In addition, a reinforcing plate 3 is provided at the bottom of the isolation net 2-2. The reinforcing plate 3 is a disc-shaped structure and is coaxially arranged with the support net 2-1. The reinforcing plate 3 is used to fix and restrict the bottom of the support net 2-1 and the isolation net 2-2 to enhance their stability. The diameter of the reinforcing plate 3 is not greater than the diameter of the support plate 1, so as to avoid setting it too large to increase the lowering resistance of the pile core cage.
[0021] Furthermore, in this embodiment, the reinforcement plate 3 is connected to the support net 2-1, the isolation net 2-2 and the support plate 1 by bolts 4. Support rods 5 are arranged at intervals around the reinforcement plate 3, and the support rods 5 are located below the isolation net 2-2. The support rods 5 are used to limit the lower part of the isolation net 2-2 to prevent the edge of the isolation net 2-2 from deforming and bending downward, resulting in a poor seal with the inner wall of the pile. At the same time, the setting of the support rods 5 can also pre-clean the debris on the inner wall of the pile that is too large in size, and prevent the large debris from directly touching the isolation net 2-2, causing the isolation net 2-2 and the support net 2-1 to undergo large uneven deformation, and thus resulting in a poor seal on the inner wall of the pile. Among them, the support rod 5 can preferably be set as a triangular prism structure with its edges facing downward, so that the debris can be cleaned by using its edges; in addition, the sum of the length of the support rod 5 and the radius of the reinforcement plate 3 is less than the radius of the isolation net 2-2, so as to prevent the support rod 5 from being too long and affecting the lowering of the pile core cage.
[0022] When the utility model is used, firstly, an isolation net 2-2 and a support net 2-1, namely a reinforcement plate 3, are arranged at the bottom of the support plate 1, and they are fixedly connected by bolts 4, and finally the support plate 1 is fixed to the bottom of the pile core cage, and the pile core cage is suspended and installed in the pipe pile, and under the action of gravity and friction, the support net 2-1 and the isolation net 2-2 will be deformed and stuck on the inner wall of the pipe pile after contacting with the debris on the inner wall of the pipe pile, so that the gap between the support plate 1 and the inner wall of the pipe pile is blocked, and when pouring concrete, the support net 2-1 and the isolation net 2-2 can effectively intercept the concrete, avoid leakage, save concrete, and at the same time ensure the solidity of the pile core concrete and the construction quality.
