Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a concrete template. Background Art

[0002] Concrete formwork is a necessary device for pouring concrete. Traditional concrete formwork is made of wooden formwork or steel formwork. Wooden formwork has the disadvantages of not being fireproof, easy to rot, and not durable, while steel formwork is bulky, expensive, and easy to rust. After searching, the application number "CN201710581005.1" discloses "a concrete formwork", which records "using this concrete formwork and concrete pouring method to allow sodium gluconate solution to seep from the first liquid outlet to the shallow surface of concrete surrounding the surface of the hole formwork after the concrete is poured. Due to the retarding effect of sodium gluconate, the concrete surrounding the surface of the hole formwork is still in a plastic state when the center and upper surface of the concrete solidify. The formwork is demoulded while ensuring the supporting force of the concrete. At this time, since the shallow surface of concrete surrounding the surface of the hole formwork is still in a plastic state, the concrete will not be crushed. Therefore, demoulding is very convenient, and the hole mold after demoulding is not yet solidified, so it is also very convenient to clean. "By using this concrete formwork and concrete pouring method, after concrete pouring, sodium gluconate solution seeps out from the first liquid outlet to the shallow surface of concrete surrounding the hole mold surface. Due to the retarding effect of sodium gluconate, the concrete surrounding the hole mold surface is still in a plastic state when the center and the upper surface of the concrete solidify. At this time, the shallow surface of the concrete surrounding the hole mold surface is still in a plastic state, so demoulding is very convenient, and the hole mold after demoulding is not yet solidified, so it is also very convenient to clean. However, there are still the following problems in actual use:

[0003] In actual use, the use of solution demoulding will cause more sticky substances to appear on the ground, which is unhygienic and the concrete cannot be pushed out quickly during use.

[0004] Based on this, it is extremely practical to provide a formwork that can achieve rapid demoulding, is relatively hygienic, and can quickly push out concrete. Utility Model Content
