Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a height-adjustable independent foundation column longitudinal reinforcing bar installation bracket. Background Art

[0002] With the vigorous development of the railway industry, the emergence of a large number of high-speed railway stations has put forward higher requirements on the structural form of buildings, and various super-large and super-thick structural components have emerged in an endless stream. In the design of the track-bearing layer structure, in order to meet the static load of the track and the dynamic load of the high-speed railway after completion, large-section and large-size independent pedestals and frame columns are often set to meet the force requirements.

[0003] According to the original steel bar atlas specification requirements, for this type of super-large and super-thick independent foundation, the longitudinal reinforcement of the columns needs to extend to the bottom plate steel mesh and be bent and anchored. The entire pedestal has a large steel content. At the same time, the longitudinal reinforcement of this type of column is large in size and heavy in weight. It takes several people to install one steel bar, and it is difficult to tie and fix the steel bars in the pedestal.

[0004] According to the latest national building standard design atlas 22G101-3, when the thickness of the foundation slab is greater than 2m (the thickness of the column cap of the track-bearing layer is generally 4m), a horizontal structural steel mesh should be set in the middle of the foundation slab; in addition, when the column is axially compressed, slightly eccentrically compressed or the column is highly eccentrically compressed, and the foundation height or the distance from the top surface of the foundation to the top surface of the middle layer of steel mesh is not less than 1.2m or 1.4m, only the longitudinal bars at the four corners of the column can be extended to the bottom plate steel mesh or the middle layer steel mesh of the raft foundation, and the remaining longitudinal bars can be anchored below the top surface of the foundation LaE. According to GB50666-2011 "Concrete Structure Construction Code", a thicker foundation can be provided with a horizontal construction joint in the middle according to construction needs.

[0005] In view of the current construction situation and the requirements of the specification drawings, an independent foundation column longitudinal reinforcement installation bracket with adjustable height is designed to solve the above problems and meet the on-site construction needs and save steel bar costs. Utility Model Content

[0006] The utility model overcomes the shortcomings of the prior art and proposes a height-adjustable independent foundation column longitudinal reinforcement installation bracket, which solves the problem of difficult steel bar installation of large-section and large-size independent foundations and frame columns, and is suitable for the installation of longitudinal steel bars of columns in large and thick independent foundations with track-bearing layers in high-speed railway stations.

[0007] In order to achieve the above purpose, the utility model is implemented through the following technical solutions.

[0008] A height-adjustable independent foundation column longitudinal dowel installation bracket comprises height-adjusting legs and a support frame; the support frame is a square frame structure, the four corners of the support frame are hollow structures, the four sides of the support frame are U-shaped groove structures, and a plurality of partition plates are evenly arranged in the U-shaped groove structure; the bottom of each side of the support frame is detachably connected with a height-adjusting leg; the support frame is kept horizontal by the support of the height-adjusting legs; the support frame is installed in the center of the column pedestal through the height-adjusting legs, the four corner steel bars of the independent foundation column pass through the hollow structure and abut against the bottom layer or middle layer steel mesh of the raft slab of the column pedestal, the bottom of the remaining steel bars of the independent foundation column abuts against the U-shaped groove structure, and a steel bar abuts between two adjacent partition plates.

[0009] Furthermore, two ends of the bottom of each side of the support frame are respectively connected with a height-adjusting leg.

[0010] Furthermore, the height-adjusting leg includes a base, a support rod, an extension rod and a height-adjusting rotating drum, the bottom of the support rod is connected to the base, the extension rod is located above the support rod, and the height-adjusting rotating drum is threadedly connected between the support rod and the extension rod.

[0011] Furthermore, a U-shaped support is connected to the top of the extension rod, the support frame is located inside the U-shaped support, and the side of the U-shaped support is connected to an adjusting screw for fixing the support frame and the U-shaped support.

[0012] Furthermore, the support frame is a U-shaped channel steel.

[0013] The beneficial effects of the utility model compared with the prior art are:

[0014] 1. The use of the mounting bracket of the utility model shortens the length of the column longitudinal reinforcement inserted into the pedestal while meeting the requirements of the specifications and drawings. It is not necessary for the bottoms of all the column longitudinal reinforcements to rest against the bottom of the pedestal or the middle layer of the steel mesh, which saves the cost of steel bars, uses steel scientifically, and avoids material waste.

[0015] 2. The mounting bracket of the utility model uses U-shaped channel steel as the steel bar support plate, which has high rigidity and strength, and will not be deformed by the pressure of the steel bar. It can accurately ensure the height of the column longitudinal reinforcement inserted into the pedestal. In addition, the column steel bar is in a suspended state in the pedestal. The use of this device can better fix the steel bar during the binding process.

[0016] 3. The U-shaped channel steel of the mounting bracket of the utility model is separated by a partition plate according to the uniform spacing of the steel bars, which can ensure that the column steel bars are evenly distributed, and there will be no displacement during the binding process, thereby improving the quality of steel bar binding, avoiding the arbitrariness of workers in inserting the bars, and improving the binding quality.

[0017] 4. The bottom of the mounting bracket of the utility model uses a height-adjusting bracket to support the U-shaped channel steel. The height can be adjusted at will according to the length of the column reinforcement inserted into the pedestal, and is suitable for pedestals of different sizes.

[0018] 5. After the column dowels are tied and fixed in the cap, lower the height adjustment bracket to lower the height of the device, pull it out from the side of the cap, and then install the template. This device is easy to install and disassemble, and can be used by construction workers of ordinary types, saving time and effort and high work efficiency.

[0019] 6. The mounting bracket of the utility model is suitable for fixing and binding reinforcement bars of pedestal columns of different sizes, and can be used cyclically, which greatly reduces the construction cost.

[0020] 7. Compared with the traditional binding method of the reinforcement bars of the pedestal column, this device simplifies the entire construction process.

[0021] The utility model aims to solve the problem of super-large and super-thick independent foundation of the track-bearing layer in high-speed railway stations, the installation of longitudinal reinforcement of columns, scientific and reasonable use of steel, and reinforcement binding installation, and provides a new type of independent foundation column longitudinal dowel installation bracket with adjustable height, which has a stable structure, safe use, convenient operation, and easy disassembly and assembly. It can easily lift the longitudinal dowel of the independent foundation column to a certain height, which is convenient for the fixing, binding and installation of reinforcement. It is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0035] See also Figure 1-10 The present embodiment proposes a height-adjustable independent foundation column longitudinal dowel installation bracket, comprising a height-adjustable support leg 1 and a support frame 2; the support frame 2 is a square frame structure, and the four corners of the support frame 2 are hollow structures 3, and the hollow structure 3 can ensure that the four corner steel bars 7 of the column pass through and rest on the bottom layer or middle layer steel mesh 8 of the raft slab; the four sides of the support frame 2 are all U-shaped groove structures, and in the present embodiment, four U-shaped channel steels are used to connect the square support frame 2.

[0036] A plurality of partition plates 5 are evenly arranged and welded in the U-shaped groove structure of the support frame 2 to ensure that the remaining steel bars 9 of the independent foundation column are not deviated during the installation and binding process.

[0037] Each side bottom of the support frame 2 is detachably connected with a height-adjusting leg 1; the support frame 2 is kept horizontal by the support of the height-adjusting leg 1; specifically, in this embodiment, each side bottom of the support frame 2 is respectively connected with a height-adjusting leg 1 at both ends.

[0038] The height adjustment leg 1 includes a honeycomb-shaped base 11, a support rod 12, an extension rod 13 and a height adjustment drum 14; wherein the support rod 12 and the extension rod 13 are both threaded steel. The bottom of the support rod 12 is connected to the base 11, the extension rod 13 is located above the support rod 12, and the height adjustment drum 14 is threadedly connected between the support rod 12 and the extension rod 13.

The side of the U-shaped support 15 is connected to an adjustment screw 16 for fixing the support frame 2 and the U-shaped support 15.

[0039] The support frame 2 is installed at the center of the column pedestal 6 through the height-adjustable legs 1. The four corner steel bars 7 of the independent foundation column pass through the hollow structure 3 and abut against the bottom layer or middle layer steel mesh 8 of the raft slab of the column pedestal 6. The bottom of the remaining steel bars 9 of the independent foundation column abuts against the U-shaped groove structure, and a steel bar is connected between two adjacent partition plates 5.

[0040] The method of using the height-adjustable independent foundation column longitudinal dowel mounting bracket is as follows:

[0041] 1. The thickness of the column pedestal 6 of the track-bearing layer is 4m. According to the concrete construction specifications, the concrete of the lower part of the pedestal can be poured first, and then its surface can be roughened and cleaned, and treated according to the treatment method of the construction joint, and then the surface mesh can be tied.

[0042] 2. After the surface mesh is tied, place the independent foundation column longitudinal reinforcement installation bracket according to the column positioning, see Figure 6 Then tie the middle steel mesh 8, and after the middle steel mesh 8 is tied, start to insert the longitudinal reinforcement of the column. Figure 7 .

[0043] 3. The four corner steel bars 7 of the independent foundation column pass through the hollow structures 3 reserved at the four corners of the mounting bracket and rest on the middle steel mesh 8. Figure 8 The remaining steel bars 9 of the independent foundation column are inserted into the supporting frame 2, and the height of the bottom of the remaining steel bars 9 of the independent foundation column from the column pedestal 6 meets the straight anchor length requirement, so it is necessary to adjust the height of the supporting frame 2 by adjusting the height of the supporting leg 1 according to the straight anchor length so that it meets the insertion height requirement of the column longitudinal reinforcement, i.e., the remaining steel bars 9.

[0044] 4. After the height and position of the column longitudinal reinforcement are fixed, the remaining steel bars 9 are welded and fixed to the steel bars around the column pedestal 6, and then the independent foundation column longitudinal dowel installation bracket is dismantled and withdrawn from the side of the column pedestal 6, followed by formwork.
