Abstract
Description
Technical Field
[0001] The utility model relates to a building construction structure, in particular to a template reinforcement structure, specifically to a tunnel anti-collision wall template reinforcement structure. Background Art
[0002] With the rapid economic growth, road traffic volume has increased dramatically and traffic congestion has become increasingly serious. The planning and construction of urban tunnels has become an important part of the expressway transportation system, greatly solving the congestion at intersections of main roads, alleviating the pressure on urban road traffic and ensuring transportation.
[0003] However, the rapid growth of traffic volume has led to frequent traffic accidents in tunnels, resulting in frequent damage to the tunnel structure. Therefore, anti-collision walls are usually built on the side walls of tunnels to reduce the impact force on the tunnel structure when vehicles collide and reduce the damage to the tunnel caused by traffic accidents.
[0004] Tunnel crash barriers are usually built after the completion of the tunnel foundation. Usually, the construction formwork is built first, and then poured. In order to ensure the stability of the construction formwork, it is also necessary to reinforce it. The traditional tunnel crash wall formwork reinforcement system is mainly composed of wood plywood formwork, square timber and steel pipes. Specifically: wood plywood is used as the crash wall formwork, square timber is used as the back rib of the wood plywood, and steel pipes are used as diagonal braces to support the back rib of the square timber on the outside of the formwork. Due to the low rigidity of the square timber, poor manufacturing precision, and the linear contact between the steel pipe and the wood square, it is easy to cause many quality problems such as poor concrete molding quality, uneven rounded corners, leakage of slurry, and actual measurement not meeting the standards. Therefore, it is urgent to design a tunnel crash wall formwork reinforcement structure to meet the appearance quality requirements of tunnel crash wall concrete pouring. Utility Model Content
[0005] The purpose of the utility model is to provide a tunnel crash wall template reinforcement structure in response to the deficiencies in the prior art. The structure is simple and the construction is convenient. The structure can ensure the stability of the template and avoid quality problems such as unsquare corners, leakage of slurry, and actual measurement not meeting the standards, thereby ensuring the appearance quality of the tunnel crash wall casting.
[0006] The technical solution of the utility model is:
[0007] A tunnel anti-collision wall template reinforcement structure, comprising a first diagonal brace, a second diagonal brace and a third diagonal brace; the first diagonal brace is arranged obliquely upward, with its proximal end abutting against the lower part of the template and its distal end abutting against the tunnel floor; the second diagonal brace is arranged obliquely upward, with its proximal end abutting against the upper end of the template and its distal end abutting against the tunnel floor; the third diagonal brace is arranged obliquely downward, with its proximal end abutting against the upper end of the template and its distal end abutting against the tunnel side wall; it also includes a square wood support; the square wood support is in the shape of a strip, and its two ends respectively abut against the upper end of the template and the tunnel side wall.
[0008] Furthermore, the first diagonal brace, the second diagonal brace and the third diagonal brace are all made of steel pipes.
[0009] Furthermore, the proximal ends of the first diagonal brace, the second diagonal brace and the third diagonal brace are respectively connected to the formwork through a top support, and the distal ends thereof are respectively connected to the tunnel floor and the tunnel side wall through anchoring steel bars.
[0010] Furthermore, the anchoring steel bar is bent and inserted into the distal ends of the first diagonal brace, the second diagonal brace and the third diagonal brace.
[0011] Furthermore, the angle between the first diagonal brace and the horizontal plane is 10° to 30°; the angle between the second diagonal brace and the horizontal plane is 30° to 45°; and the angle between the third diagonal brace and the horizontal plane is 45° to 60°.
[0012] Furthermore, a tension seat is provided at the upper end of the template; the proximal end of the square timber support is clamped on the tension seat, and the distal end thereof is pressed against the side wall of the tunnel.
[0013] Furthermore, the first diagonal brace, the second diagonal brace, the third diagonal brace and the square wood support are all multiple and evenly distributed along the template.
[0014] Beneficial effects of the utility model:
[0015] The utility model has reasonable design, simple structure and easy use.

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1 shown.
[0020] A tunnel crash wall template reinforcement structure includes a first diagonal brace 5, a second diagonal brace 7, a third diagonal brace 10 and a square wood support 9. The template 4 is a customized steel template with the same size as the crash wall in the design drawing, including a panel. The back side of the panel is provided with a plurality of transverse ribs to ensure that the template has sufficient strength.
[0021] The first diagonal brace 5 is arranged obliquely upward, with its proximal end abutting against the lower part of the template 4 at a distance of about 10 cm from its lower end, and its distal end abutting against the tunnel floor 2. The angle between the first diagonal brace 5 and the horizontal plane is 10° to 30°, so that it can effectively support the lower part of the template and prevent the lower end of the template from moving outward.
[0022] The second diagonal brace 7 is arranged obliquely upward, with its proximal end abutting against the upper end of the template 4 and its distal end abutting against the tunnel floor 2. At the same time, the angle between the second diagonal brace 7 and the horizontal plane is 30° to 45°, so as to support the upper end of the template 4 and prevent the upper end of the template from moving outward.
[0023] The third diagonal brace 10 is set diagonally downward, with its proximal end against the upper end of the template 4 and its distal end against the tunnel side wall 1. At the same time, the angle between the third diagonal brace 10 and the horizontal plane is 45° to 60°, so that it supports the panel on the vertical plane and prevents the template from moving upward.
[0024] The square timber support 9 is in the shape of a strip, and its two ends are respectively against the upper end of the template 4 and the tunnel side wall 1, and are in a horizontal state, which can prevent the upper end of the template from moving inward. Preferably, a tension seat 8 is provided at the upper end of the template 4, and the proximal end of the square timber support 9 can be clamped on the tension seat 8, and the distal end thereof can be pressed against the tunnel side wall 1, which is convenient for operation and can ensure that the square timber support is firmly installed.
[0025] The first diagonal brace 5 , the second diagonal brace 7 and the third diagonal brace 10 are all made of steel pipes, which are convenient for manufacture and use.
[0026] The proximal ends of the first diagonal brace 5, the second diagonal brace 7 and the third diagonal brace 10 are respectively connected to the template 4 through a jacking support 6. The jacking support 6 is a conventional product, which can be conveniently connected to a steel pipe, and the support length of the corresponding diagonal brace can be adjusted by screwing the jacking screw on the jacking support to meet the requirements of support reinforcement.
[0027] The distal ends of the first diagonal brace 5, the second diagonal brace 7 and the third diagonal brace 10 are respectively connected to the tunnel floor 2 and the tunnel side wall 1 through anchoring steel bars. The anchoring steel bars are embedded in the tunnel floor and the side wall through punching, and then bent into the same angle as the corresponding diagonal brace, and then inserted into the distal ends of the corresponding diagonal brace, so that the distal ends of the first diagonal brace, the second diagonal brace and the third diagonal brace are firmly abutted, and the materials are convenient to obtain and the operation is simple.
[0028] The first diagonal brace 5 , the second diagonal brace 7 , the third diagonal brace 10 and the square wood support 9 are all multiple and evenly distributed along the template 4 , so that the template is evenly reinforced.
[0029] During construction, first place the positioning steel bar 3 on the tunnel floor corresponding to the lower end of the template, then install the template 4 in place, and make its lower end rest against the positioning steel bar 3. Subsequently, the first diagonal brace 5, the second diagonal brace 7 and the third diagonal brace 10, as well as the square wood support 9, are installed in place to effectively reinforce the template.
[0030] The utility model comprehensively reinforces the formwork by means of a plurality of diagonal braces at different angles and square timber supports in the horizontal direction, effectively avoiding problems such as top floating, bottom leakage and upper mouth displacement that may occur when pouring concrete, improves the overall stability of the formwork, and makes the appearance quality beautiful and the lines smooth after demoulding.
[0031] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
