Green fixing device for vertical template square steel of welded elbow and construction method of green fixing device

Abstract

The invention discloses a green fixing device for vertical template square steel of a welded elbow and a construction method of the green fixing device, and belongs to the technical field of construction. The green fixing device for the vertical template square steel of the welded elbow comprises a square steel keel. The front side of the square steel keel is in overlap joint with four secondary keels, and the back of the square steel keel is in overlap joint with the front of a template. According to the green fixing device for the vertical template square steel of the welded elbow, the square steel keel, a steel bar elbow, the secondary keels and fasteners are arranged, when the staff needs to fix the square steel keel to the template, then the fasteners are fixed to the template throughsplit bolts, and the fasteners and the split bolts are arranged, so that the green fixing device is low in cost and high in speed and can be recycled, the through-end head of the square steel keel iswelded to the steel bar elbow, installation and disassembly are convenient, construction is convenient, and labor cost input is low; and the scrap rate of the square steel keel is low, the number oftimes of turnover is high, the residual value is high, the material is saved, the use of square wood strips is reduced, the forest is protected, and the sustainable development of resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a green fixing device for welding elbow vertical formwork square steel and a construction method thereof. Background technique [0002] In the 1980s, the world put forward the definition of sustainable development. Followed by China, it also practiced the strategy of sustainable development and strived to build a resource-saving and environment-friendly society. Since the development of construction projects, in the construction of formwork projects, due to Wooden strips have a certain bending resistance, and a large number of wooden square strips are used as the keel of the support system for reinforcement. In the existing formwork construction, due to the use of fixed wooden square strips, its rigidity and bending strength are far inferior to steel. Formwork support Reinforcement needs to use a large amount of square wood materials to ensure its strength, which is not cond...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a green fixing device for welding elbow vertical formwork square steel, which solves the problem of rigidity and bending strength due to the use of fixed wooden square strips in the existing formwork construction. It is far inferior to steel, and a large amount of square wood materials are required to ensure its strength for formwork support and reinforcement, which is not conducive to saving materials, and wooden strips are used as formwork to strengthen the support keel, which is prone to insufficient strength at the bottom of the column foot wall, resulting in wall column concrete pouring. Disadvantages such as mold expansion and violent mold cause waste of materials and labor. When using wooden strips, a large amount of forest resources need to be cut down. Colleagues who do not conform to the national policy of sustainable development and green construction concepts, compared with steel strips, wooden strips are not conducive to secondary construction. There is a lot of waste to be used, and it is inconvenient to fix the wooden square strips. It needs to be fixed to the formwork with iron nails, which may easily cause damage to the square wood and wall column formwork, which is not conducive to the turnover and recycling of materials, and once the nails are nailed, it is not easy to adjust.
