[0010] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0011] See also Figure 1 A tool for welding and fixing a bridge support arm, comprising a fixing column 1 fixed to a bridge column, wherein the fixing column 1 is connected to the bridge column through a bridge column bayonet 2, the bridge column bayonet 2 is fixed to one side of the fixing column 1, buckled on the bridge column, and fixed to the bridge column with a tightening bolt Ⅰ3.

[0012] A three-layer cross brace support arm 4 is provided on the other side of the fixed column 1. The cross brace support arm 4 adopts a cantilever structure, and the fixed end is vertically connected to the fixed column 1 in an adjustable position. A bridge support arm bayonet 5 is provided on the cross brace support arm 4, and a fixing bolt II 6 is provided on the bridge support arm bayonet 5.

[0013] In this embodiment, the fixing bolts I3 include two mutually perpendicular ones, so as to stabilize the fixing column 1. Three fixing holes are provided on the fixing column 1 corresponding to each of the cross bracing arms 4, and the cross bracing arms 4 are connected to the fixing column 1 by bolts.

[0014] The process of installing the bridge support arm by using the above-mentioned tooling is: on-site positioning and marking - prefabrication of the bridge support arm - on-site spot welding and fixing - welding - polishing and anti-corrosion. The spacing is determined in advance by the tooling and no on-site measurement is required, thus saving the on-site spacing measurement step; after the tooling is fixed, no manual labor is required to assist in fixing it, and the installation of the bridge support arm can be completed by one person; the tooling can fix three layers of bridge support arms at the same time, and can complete the welding of three layers of support arms at one time, which can greatly improve the construction efficiency and save labor, and is particularly suitable for the welding of concentrated, multi-layered, and large-scale bridge support arms.

[0015] Examples of the production and application of the above tooling:

[0016] See also Figure 1, select a #5 or #8 channel steel to make a fixed column 1, select a 40x40x4mm angle steel to make a cross brace arm 4, weld the bridge column bayonet 2 to the fixed column 1, the bridge column bayonet 2 has two fixing bolts Ⅰ3 on the side and top, and the tooling position can be adjusted to fix it on the bridge column. There are at least two bridge column bayonet 2 to ensure that the tooling has at least two fixing points to avoid the horizontality of the cross brace arm not meeting the standard after bearing the load. Each cross brace arm 4 has three bolt connection holes with a spacing of 50mm on the fixed column 1, which are used to adjust the spacing of the cross brace arm 4. A bridge support arm bayonet 5 is set on the cross brace arm 4, and each bridge support arm bayonet 5 is equipped with a fixing bolt Ⅱ6.

[0017] The above tooling is easy to make, can be made from local materials, and is convenient to use. The tooling has five adjustable positions of 600mm, 550mm, 500mm, 450mm, and 400mm, and can fix three bridge brackets at a time. It does not require labor to assist in construction. A familiar post leader plus a welder can complete the work. It greatly reduces the measurement time and the use of labor during the construction process, not only does the construction efficiency increase by more than double, but also saves at least 30% of labor costs.
