Pre-embedded fastener of green building fabricated type steel structure and forming method

Abstract

The invention discloses a pre-embedded fastener of a green building fabricated type steel structure. The pre-embedded fastener comprises a pre-embedded fastener body and a forming device used for manufacturing the pre-embedded fastener body, the pre-embedded fastener body comprises a connecting base and a pre-embedded foot fixed to the connecting base, and the pre-embedded foot is formed by extending outwards from the bottom of the connecting base. According to the pre-embedded fastener, building base materials are subjected to primary reinforcement and secondary reinforcement through the pre-embedded foot and an auxiliary bar respectively, so that the pre-embedded fastener good in mechanical property and high in bearing capacity is obtained; meanwhile, the pre-embedded fastener is machined in an integrated pouring mode, the bending and deviation adjustment process of steel bars is avoided, and the machining efficiency is improved; and a mold temperature mechanism and an exhaust mechanism are arranged on a forming device for machining the pre-embedded fastener, so that the liquidity of molten steel in the pouring process is maintained, the defects of cold shut and under-casting at a hook-shaped structure of the pre-embedded fastener are avoided, gas in a cavity is released through the exhaust mechanism, meanwhile, ejection defect of the molten steel is avoided, and the machining precision of the pre-embedded fastener is jointly improved.

Description

technical field [0001] The invention relates to the technical field of building fasteners, in particular to a pre-embedded fastener for a green building assembly type steel structure and a forming method. Background technique [0002] Embedded fasteners are the components pre-installed in the concealed project, which are the components placed during the pouring of the structure, and are used for lap joints during the masonry superstructure. Among them, during construction, the embedded fasteners of the steel structure are Commonly used embedded parts. Although the pre-embedded fasteners used in the construction field are in various forms and varieties, they are nothing more than composed of a pre-embedded tank body connection seat and a pre-embedded rib fixed on the connection seat. The used connection seat is C-shaped. The embedded reinforcement used is rebar and H-shaped steel. A large number of application practices have shown that this kind of pre-embedded fastener has...
