Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a formwork support device for building walls. Background Art

[0002] The formwork support device for building walls is an indispensable part of construction. It is mainly used to fix and support wall materials during the construction process to ensure the accuracy of the shape, size and position of the wall.

[0003] Traditional building formwork generally includes panels, transverse reinforcement ribs, vertical reinforcement ribs and diagonal supports, and is mostly made of composite wood boards. During construction, the panels are first spliced ​​on site according to the size of the wall to be constructed, and then the panels are positioned on both sides of the wall to be processed. The transverse and longitudinal reinforcement ribs are fixed to the outside of the panels by screws or the like to strengthen the panel strength, and finally the panels are fixed by diagonal supports.

[0004] With regard to the above-mentioned related technologies, each time a wall is poured, the formwork needs to be spliced ​​on site according to the size of the wall, and needs to be fixed with screws or the like, which makes the construction troublesome and inefficient. Utility Model Content
