Description

Technical Field

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

[0002] Casting forms, also known as concrete forms or formwork systems, are structures used in construction to shape and support newly poured concrete until it hardens and can bear its own weight. These forms are usually used for prefabricated building load-bearing beams or directly cast building beams. When casting prefabricated building load-bearing beams, in order to ensure that the concrete structure reaches the expected shape, size and safety standards, the casting forms need to be fixed before pouring.

[0003] There are various types of casting formwork, which are mainly divided by material: wooden formwork, steel formwork, aluminum formwork, etc., among which this is one of the most common types of formwork, usually made of plywood, wood board or other wood. Wooden formwork is relatively cheap and easy to process. When using wooden formwork to build casting formwork, it is necessary to splice the wooden formworks. In the prior art, bricks are usually used to partition between two wooden formworks, and then a fixing nail is driven into between the two wooden formworks by an electric drill, and then the two ends of the fixing nail are twisted and fit between the two wooden formworks for limited fixing, so as to achieve a fixing effect. This fixing method has problems in actual use. When the formwork needs to be removed after the concrete is poured and solidified, the fixing nail needs to be twisted and reset again, and then the formwork fitted to the concrete surface is manually pulled out. It is more laborious to remove the casting formwork, which is easy to cause a waste of human resources. Utility Model Content
