Description

Technical Field

[0001] The utility model relates to the field of bridge construction guardrails, in particular to a guardrail for bridge construction. Background Art

[0002] With the development of society and economy, more and more bridges are being built. Bridges play a vital role in modern society. They can not only connect traffic, shorten distances, and improve flow across natural and artificial barriers, but also promote trade, drive regional development, create jobs, facilitate travel, promote cultural exchanges, and ensure national security. At the same time, they can reduce damage to the ecology and provide passages for wild animals. They are a symbol of the progress of human civilization and have made great contributions to life and social development.

[0003] During the bridge construction process, safety assurance is of vital importance. For this purpose, a special guardrail for bridge construction is required. A common type of guardrail for bridge construction mainly realizes its protective function by setting up columns and protective nets. In actual use, it is only necessary to place the columns in the appropriate position and then hang the protective net on the outer wall of the column's installation hook. The installation method is simple and convenient, which improves construction efficiency.

[0004] However, the current guardrail for bridge construction has certain limitations in actual application. It is mainly installed by hanging the protective net on the outer wall of the installation hook of the column. During actual use, this installation method is prone to the angle deflection of the protective net, which in turn leads to the lack of stability of the entire guardrail. This may cause safety hazards in a dangerous working environment such as bridge construction. Therefore, it is urgent to improve and optimize it to improve the stability and reliability of the guardrail and better ensure the safe progress of bridge construction. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a guardrail for bridge construction to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guardrail for bridge construction, comprising a guardrail main body, the guardrail main body consisting of a column and a protective net, a first mounting block and a second mounting block fixedly installed at the end of the protective net, a support foot rotatably installed at the bottom of the column, and a first limit block and a second limit block fixedly installed on the outer walls on both sides of the column, and a storage groove corresponding to the support foot is provided at the bottom of the column, and a sliding groove is provided inside the first limit block.

[0007] By adopting the above technical solution, the installation operation of the guardrail body becomes extremely convenient, saving installation time and labor costs, improving construction efficiency, and greatly enhancing the stability of the device. The support foot effectively limits the position of the protective net by cooperating with the second limit block to prevent it from offsetting or shaking, ensuring that the protective net always maintains a stable protective state during use, and increases the contact area and friction between the column and the ground, significantly improving the stability of the column, making the entire device not only simple and convenient to install in complex environments such as bridge construction, but also able to reliably play a protective role, effectively reducing the safety risks that may be caused by unstable installation of the device, and providing solid safety protection for bridge construction personnel.

[0008] Furthermore, the cross-section of the first mounting block is designed to be inverted L-shaped, and two groups of first mounting blocks are symmetrically arranged near the top at both ends of the protective net, and the inner corners of the bottom end of the first mounting block are designed to be inclined.

[0009] By adopting the above technical solution, the first installation block and the first limiting block cooperate with each other to limit the position of the protective net, which facilitates installation and enhances the stability of the device.

[0010] Furthermore, two groups of the second mounting blocks are symmetrically arranged on the outer walls on both sides of the bottom of the protective net, and the length of the second mounting blocks corresponds to the length of the first mounting blocks.

[0011] By adopting the above technical solution, the position of the protective net can be further limited, ensuring the stability of the installation of the protective net.

[0012] Furthermore, two groups of support legs are symmetrically arranged at the bottom of the column, and the rotation range of the support legs is 0-30 degrees, and the outer wall of the end portion of the support legs fits with the outer wall of the protective net when the support legs are in the open state.

[0013] By adopting the above technical solution, the supporting feet can effectively limit the position of the protective net by cooperating with the second limit block to prevent it from shifting or shaking, ensuring that the protective net always maintains a stable protective state during use. It also increases the contact area and friction between the column and the ground, significantly improving the stability of the column, making the entire device not only simple and convenient to install in complex environments such as bridge construction, but also able to reliably play a protective role, effectively reducing the safety risks that may be caused by unstable installation of the device, and providing solid safety protection for bridge construction workers.

[0014] Furthermore, the second limiting block is designed to correspond to the second mounting block, and the inner wall of the second limiting block fits the outer wall of the second mounting block, and the top of the second limiting block is close to the corner of one side of the second mounting block and is designed to be inclined.

[0015] By adopting the above technical solution, the second installation block is easy to install, and the protective net is further limited to enhance stability.

[0016] Furthermore, the cross section of the first limit block is U-shaped, the length of one side of the first limit block close to the second limit block is shorter than the length of the other side of the first limit block, and the inner corner of the top of the first limit block is inclined.

[0017] By adopting the above technical solution, when installing the protective net, it is only necessary to counteract the first installation block with the first limit block, and there is no need to accurately align the first installation block with the first limit block, which facilitates installation.

[0018] Furthermore, the sliding groove is arranged corresponding to the first installation block, and the inner wall of the sliding groove is in contact with the outer wall of the first installation block.

[0019] By adopting the above technical solution, the position of the first installation block is restricted, which makes the installation simple and convenient, improves the construction efficiency and enhances the stability.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model is provided with a storage groove, a first installation block, a second installation block, a supporting foot, a first limit block, a slide groove and a second limit block, which makes the installation operation of the guardrail body extremely convenient, saves installation time and labor costs, improves construction efficiency, and greatly enhances the stability of the device. The supporting foot effectively limits the position of the protective net by cooperating with the second limit block to prevent it from offsetting or shaking, ensuring that the protective net always maintains a stable protective state during use, and increases the contact area and friction between the column and the ground, significantly improving the stability of the column, making the entire device not only simple and convenient to install in complex environments such as bridge construction, but also able to reliably play a protective role, effectively reducing the safety risks that may be caused by unstable installation of the device, and providing solid safety protection for bridge construction personnel.

[0034] See also Figure 3 and Figure 4 There are two groups of second mounting blocks 32 symmetrically arranged on the outer walls on both sides of the bottom of the protective net 3, and the length of the second mounting blocks 32 corresponds to the length of the first mounting blocks 31, so as to further limit the position of the protective net 3 and ensure the stability of the installation of the protective net 3.

[0035] See also Figure 1 - Figure 7 Two groups of supporting feet 4 are symmetrically arranged at the bottom of the column 2, and the rotation range of the supporting feet 4 is 0-30°, and the outer wall of the end portion of the supporting feet 4 is in contact with the outer wall of the protective net 3 when the supporting feet 4 are opened. The supporting feet 4 effectively limit the position of the protective net 3 by cooperating with the second limit block 6 to prevent it from deflecting or shaking, ensuring that the protective net 3 always maintains a stable protective state during use, and increases the contact area and friction between the column 2 and the ground, significantly improving the stability of the column 2, making the entire device not only simple and convenient to install in complex environments such as bridge construction, but also able to reliably play a protective role, effectively reducing the safety risks that may be caused by unstable installation of the device, and providing solid safety protection for bridge construction personnel.
