Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a welding device for the construction of a post-casting belt closing net. Background Art

[0002] Construction joints often appear in building construction. In dry environments or areas without water, construction joints do not require special treatment. Simply clean them and remove the loose concrete before pouring the second concrete. However, in areas with potential water seepage risks, waterstops must be installed to ensure that the construction joints between the new and old concrete do not seep. The quick-and-easy closing net and the no-disassembly formwork are used instead of the traditional formwork. Combined with the construction of steel plate waterstops, one-time forming does not require disassembly of the formwork, and there is no need to chisel roughening. This effectively reduces the labor intensity of operators, saves traditional formwork materials, reduces construction costs, reduces the generation of waste formwork materials, is environmentally friendly and energy-saving, and has a good effect on controlling the common quality problems of leakage in the post-casting joints of underground structures. The closing net can be welded using a welding device.

[0004] However, the closing net is fixed in position by using several anti-skid protrusions, and the closing net itself is designed as a "V"-shaped structure with ups and downs. It is not stable to fix it using anti-skid protrusions. Therefore, we propose a welding device for the construction of the closing net of the post-cast strip. Utility Model Content
