Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, particularly to a construction template for a concrete building staircase. Background Technique

[0002] The staircase is an essential structural member for each project, generally formed by pouring concrete. Before pouring, various templates need to be erected according to the dimensions of the staircase in the design. After the concrete is poured and solidified, the templates are disassembled to obtain the required staircase.

[0003] Currently, during the staircase pouring process, wooden templates are mostly used, supported by square timbers, and the wooden templates are connected by driving nails. It is inconvenient to disassemble, affecting the reuse of the templates, and auxiliary reinforcement is often required between the templates, resulting in a long artificial formwork support time.

[0004] In view of this, research and improvement are carried out on the existing problems, and a construction template for a concrete building staircase is provided, aiming to solve the problems and improve the practical value through this technology. Content of the Utility Model

[0008] As a further optimization of this technical solution, the step template of the construction template for a concrete building staircase of the utility model is a plate-like structure with an "I" shape in a top view.

[0009] As a further optimization of this technical solution, the nail fixing groove of the construction template for a concrete building staircase of the utility model is a U-shaped groove with an opening downward.
