Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a building template fixing structure. Background Art

[0002] With the development of science and technology, the performance of ordinary concrete has been greatly improved, and its finished product has a high density. For concrete structures with air defense requirements, great strength and rigidity are required. In actual engineering applications, the requirements of resisting special loads or deformation can be met by increasing the thickness. Usually, the thickness of components in such buildings needs to be increased to 3-10 times the thickness of ordinary building components, so there are higher rigidity requirements for large-size concrete structural walls or structural column support formwork.

[0003] In the prior art, the support and fixation of the building structure support column formwork mainly relies on the tension water stop bolts. This traditional process can play a good fixing role for the conventional size of the structural column formwork, but for the columns that are 2-3 times the size of ordinary building structure columns, this fixing method makes the formwork unstable and prone to deformation, and even explosion. After the construction is completed, there are more traces of tension steel bars, which weakens the structural section. Utility Model Content

[0009] In one embodiment, the tension bolt comprises:

[0010] A screw rod, both ends of which extend out from the middle gap of the double-jointed channel steel on opposite surfaces;
