[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.
[0013] Example: Figure 1 As shown, a supporting and fixing device for lattice column welding processing includes a positioning frame 1 arranged on the periphery of the lattice column angle steel 2 and a positioning rod arranged inside the lattice column angle steel 2.
[0014] The positioning frame 1 includes four frame edges with adjustable lengths, each of which includes two first channel steels that are nested together and each of which is provided with a first connecting groove. The two first connecting grooves are connected by first fastening bolts. The first channel steels at the connection points of adjacent frame edges are welded together to form an integral positioning frame 1. The size of the positioning frame 1 is adjusted according to the outer dimensions of the lattice column by adjusting the position of the first fastening bolts in the first connecting grooves and pulling the first channel steels so that the positioning frame 1 can tightly wrap around the four lattice column angle steels 2.
[0015] Furthermore, the positioning rod includes two rods with adjustable lengths, the two rods being cross-shaped and hingedly connected by a connecting rod 9, which is made of a steel pipe. The rods include two I-beams 4, the opposite ends of the two I-beams 4 being connected by a second channel steel 5. The second channel steel 5 is provided on both sides of the I-beam 4, and the I-beam 4 and the second channel steel 5 are both provided with a second connecting groove 7. The two second connecting grooves 7 are connected by a second fastening bolt 6. The opposing ends of the two I-beams 4 are each provided with a supporting angle steel 3 that matches the profile of the lattice column angle steel 2, so that the positioning rod can tightly support the four lattice column angle steels 2 and cooperate with the positioning frame 1 to reliably fix the lattice column angle steel 2. After the relative angle of the two rods is adjusted, the two rods are sequentially welded and fixed using four fixing rods 8 made of steel bars.
[0016] The device of this embodiment can accurately and stably fix the angle steel of the lattice column, ensure the size of the lattice column, and facilitate welding the steel tie plate to the angle steel to form the lattice column; based on the size adjustable function of the supporting and fixing device, it can be applied to the processing of lattice columns of different design sizes, and has strong applicability; in addition, the device can be made of common materials on site and can be reused, which is convenient for on-site construction operations and is economical and environmentally friendly.
