Problems solved by technology
However, this kind of suspended fire receiver is not closed, has poor stability, takes up a lot of space, and has no protective measures around it, so there is a danger of falling, and the windproof effect is poor, and it has no heat preservation function. After repeated use, it is easy to cause deformation and affect Effect

Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] A high-altitude windproof and thermal insulation welding method for steel beams, the method is based on a windproof thermal insulation box, the windproof thermal insulation box includes a frame body 2 and a windproof shield 3, such as figure 1 , 2 As shown; the frame body 2 includes two rectangular frames and four uprights; the two rectangular frames are arranged in parallel, and the two ends of the uprights are respectively connected to the top corners of a rectangular frame to form a rectangular parallelepiped frame as a whole The frame body 2; the middle part of a pair of mutually parallel ribs on the bottom surface of the frame body 2 has a fracture respectively, which is used to snap into the vertical plate of the steel beam 5 to be welded; There are C-shaped clamps 1, and the openings of the C-shaped clamps 1 on the two columns on the same facad...

The invention discloses a windproof and insulating welding method for steel beams at high altitudes. Based on a windproof insulating box, a rack body and a windproof protective cover are provided. The rack body is provided with clamping positions formed by a C-shaped clamp; and the windproof protective cover is a box body with an opened upper end. The method comprises steps of (S1) two steel beams to-be-welded are clamped into the rack body, so upper wing plates of the two to-be-welded steel beams can be placed in a set of clamping positions in respective; (S2) the C-shaped clamp is adjusted, so the upper wing plates of the two to-be-welded steel beams can be clamped; (S3) a welding tool extends into a welding port to weld contact surfaces of the two to-be-welded steel beams; and (S4) the windproof protective cover is filled with fireproof insulating rock wool for head insulation, until the temperature restores to the indoor temperature. Onsite high-altitude welding construction efficiency, construction quality and safety can be greatly improved; and the method has wide application prospect.
Description
technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a high-altitude windproof and thermal insulation welding method for steel beams. Background technique [0002] At present, in the field of building construction, the installation and connection of steel components (objects to be welded) are mainly welded or bolted. In some low-temperature areas or during construction in winter, on-site high-altitude welding needs to be preheated before welding and heat-insulated after welding, and the welding process must not be affected by wind to ensure the quality of the weld. During on-site welding construction, a large number of sparks are often generated, and it is very easy to cause personal injury below and cause a fire when crossing operations at high altitudes. Affected by factors such as the narrow working surface and the distance from the ground, once an accident occurs, it is difficult to carry out emergency rescue, and...
