Abstract

The invention relates to a self-shearing pin for heat-insulation building formworks. The self-shearing pin is suitable to be used as a fixing connector for the heat-insulation building formworks and wood ridges of connecting formwork frames and comprises an iron pin, a modified ABS (acrylonitrile butadiene styrene) pin rod and an adhesive layer. The rear end of the iron pin is adhered with the front end of the modified ABS pin rod by the adhesive layer, a conical pin head is arranged at the front of the iron pin, and a conical connecting head is arranged at the rear end of the iron pin; a pin cap is arranged at the rear end of the modified ABS pin rod, a pin rod is arranged in the middle of the modified ABS pin rod, and a conical connecting fork is arranged at the front end of the modified ABS pin rod; water guide grooves are formed in the conical connecting fork; a center water guide hole is formed in the center of the pin rod and is communicated with the water guide grooves formed in the conical connecting fork.

Description

technical field [0001] The invention relates to a self-breaking nail for a building thermal insulation formwork, which is suitable for fixing a wooden corrugated connector between a building thermal insulation formwork and a connecting formwork frame. Background technique [0002] At present, the building thermal insulation formwork is fixedly connected with the wooden flute of the connecting formwork frame, and the connection is fixed by iron. After the concrete pouring is completed, the wooden flute of the formwork frame needs to be removed. , The decline in waterproof performance will affect the quality of the overall construction project. Contents of the invention [0003] The present invention provides a self-breaking nail for building thermal insulation formwork aiming at the above disadvantages. The rear part of the self-breaking nail adopts a modified ABS (engineering plastic) nail rod, which is connected with an iron nail through an adhesive layer, and the buildin...
