[0002] During the construction of bridges, it is usually necessary to connect the diagonal brace with the empty steel pipe of the column to meet the construction requirements. At the local joint between the diagonal brace and the empty steel pipe of the column, in order to prevent the deformation and damage of the steel pipe in the column hole, concrete is usually poured in the empty steel pipe of the column, but there are the following defects:
[0003] (1) The joint between the diagonal brace and the column empty steel pipe is usually located in the middle of the steel pipe, so it is necessary to pour about 1-2m of concrete in the middle of the steel pipe, which is difficult to operate;
[0004] (2) Pouring concrete on a part of the steel pipe increases the weight of the steel, making it inconvenient to turn around and resulting in a waste of materials;
[0005] (3) In order to adapt to the connection with the column, the connecting end of the diagonal brace and the column needs to be cut into a groove to dock with the column, which requires high precision and is difficult to operate on site. Utility Model Content

[0032] Aiming at the problem that the joint between the diagonal brace 2 and the column hollow steel pipe 1 is prone to deformation, the present application discloses a joint structure between the diagonal brace 2 and the column hollow steel pipe 1. Figure 1 and Figure 2 , which can improve the safety of the joint between the diagonal brace 2 and the column empty steel pipe 1, reduce construction costs and improve construction efficiency.
[0033] The diagonal brace 2 and the column hollow steel pipe 1 docking structure of the present application includes a diagonal brace 2 and a column hollow steel pipe 1 docked with each other, the column hollow steel pipe 1 is provided with a ring plate 3 at the docking place with the diagonal brace 2, and a corbel 4 extending outward away from the column hollow steel pipe 1 is provided on one side of the ring plate 3, and the corbel 4 is used to connect with the diagonal brace 2, so as to achieve the docking between the diagonal brace 2 and the column hollow steel pipe 1, and there is no need to pour concrete inside the column hollow steel pipe 1 to prevent the deformation of the steel pipe, and the operation is simple. In addition, the end face of the diagonal brace 2 connected with the corbel 4 is a flush section, and the diagonal brace 2 is directly connected to the corbel 4 through its flush section, and there is no need to cut the end face of the diagonal brace 2 into a groove matching the column hollow steel pipe 1, which reduces the cutting accuracy of the diagonal brace 2 and makes the on-site construction quality easy to control.
[0034] It should be noted that the flush section is usually the cross-section of the steel pipe. The end face of the steel pipe is usually set as a flush end face when it leaves the factory for easy construction. However, the connection method between the conventional diagonal brace and the column requires that the end of the diagonal brace be set to a bevel section that fits the surface of the column, which requires further processing of the end of the steel pipe, and the required precision is high and difficult to control.
[0035] The ring plate 3 can be directly sleeved on the column empty steel pipe 1, or the ring plate 3 adopts a petal structure, and the workers can directly splice the ring plate 3 on the column empty steel pipe 1 to adapt to different construction scenes. The inner side of the ring plate 3 and the outer side wall of the column empty steel pipe 1 are fully welded. The inner diameter of the ring plate 3 in this embodiment is equal to or slightly larger than the outer diameter of the column empty steel pipe 1 to be constructed, and the thickness of the ring plate 3 ranges from 1 to 2 cm, so that the ring plate 3 can strengthen the local bearing capacity of the column empty steel pipe 1 while avoiding adding too much weight to the column empty steel pipe 1.
[0036] The ring plate 3 of the present application is provided with two upper and lower pieces along the axial direction of the column hollow steel tube 1, and the corbel 4 is fixed between the upper and lower ring plates 3. The corbel 4 includes at least two parallel corbel plates, which are provided in the vertical direction, and the upper and lower sides of the corbel plates are fully welded to the upper and lower ring plates 3 respectively. In this embodiment, three corbel plates are provided in parallel, and the diagonal brace 2 is supported by the three corbel plates, which can meet the support requirements for the diagonal brace 2.
[0037] The corbel 4 is provided with a diagonal brace groove for connecting with the diagonal brace 2. The slope of the diagonal brace groove is the tangent value of the angle between the diagonal brace 2 and the empty steel pipe 1 of the column. The slope of the diagonal brace groove can be adjusted to achieve the diagonal brace 2 and the empty steel pipe 1 of the column through the flush section, thereby reducing the cutting accuracy requirements of the diagonal brace 2 and making it easy to control the on-site construction quality.
[0038] Furthermore, a stiffening plate 5 is provided between the diagonal brace 2 and the diagonal brace groove of the corbel 4. The stiffening plate 5 is located on the outer side of the diagonal brace 2 away from the column hollow steel tube 1. The stiffening plate 5 enhances the connection strength between the diagonal brace 2 and the corbel 4, and improves the connection stability between the diagonal brace 2 and the column hollow steel tube 1. In this embodiment, the thickness of the stiffening plate 5 ranges from 1 to 2 cm. While the diagonal brace 2 and the corbel 4 are connected by the stiffening plate 5 to improve the connection strength, it also avoids adding too much weight to the column hollow steel tube 1 by providing the stiffening plate 5.
[0039] During the construction of the butt joint structure of the diagonal brace 2 and the column empty steel pipe 1 of the present embodiment, the column empty steel pipe 1 is installed first, and then the upper and lower ring plates 3 are welded at the joint position where the column empty steel pipe 1 needs to be butt jointed with the diagonal brace 2, the corbel 4 is welded between the two ring plates 3, and the slope of the diagonal brace groove of the corbel 4 is adjusted, the diagonal brace 2 profile is cut, and welded to the diagonal brace groove of the installed corbel 4, thereby completing the butt joint of the diagonal brace 2 and the column empty steel pipe 1.
[0040] Alternatively, in other embodiments, the ring plate 3 and the corbel 4 may be pre-spliced first, and then the column hollow steel pipe 1 and the diagonal brace 2 may be installed according to the structure formed by the spliced ring plate 3 and the corbel 4 .
[0041] In summary, the butt joint structure of the diagonal brace 2 and the column empty steel pipe 1 of the present application realizes the connection with the diagonal brace 2 by welding the ring plate 3 and the corbel 4 on the outer surface of the column empty steel pipe 1. It has good bearing capacity and simple operation. There is no need to pour concrete in the column empty steel pipe 1, and the turnover of the column empty steel pipe 1 is not affected. The added mass of the column empty steel pipe 1 by the welded ring plate 3 and the corbel 4 can be ignored, the structural loss of the column empty steel pipe 1 is small, the requirements for on-site precision control are low, and the on-site docking quality and efficiency are improved.
[0042] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
