A kind of green building prefabricated steel structure embedded fastener and forming method

Abstract

The invention discloses a green building prefabricated steel structure pre-embedded fastener, comprising the pre-embedded fastener and a forming device used for the manufacture of the pre-embedded fastener. The pre-embedded fastener comprises a connection seat and a The pre-embedded feet fixed by the connection seat are provided at the bottom of the connection seat and extend outward. In the invention, the pre-embedded feet and the auxiliary ribs are used to reinforce the building base material once and for the second time, so as to obtain the pre-embedded fasteners with good mechanical properties and high bearing capacity, and at the same time, the pre-embedded fasteners are processed by the integrated casting method. Avoid the bending and deviation adjustment process of the steel bar, improve the processing efficiency, and set the mold temperature mechanism and the exhaust mechanism on the forming device for processing the embedded fasteners to maintain the fluidity of the molten steel during the pouring process and avoid causing pre-installation. There are cold isolation and under-casting defects at the hook structure of the embedded fastener, and the gas in the cavity is released through the exhaust mechanism to avoid the ejection defect of the molten steel, and jointly improve the machining accuracy of the embedded fastener.

Description

technical field [0001] The invention relates to the technical field of building fasteners, in particular to a green building prefabricated steel structure embedded fastener and a forming method. Background technique [0002] Pre-embedded fasteners are components pre-installed in concealed works, which are components placed during the pouring of the structure, and are used for lap joints when building the superstructure. During construction, the embedded fasteners of steel structures are Commonly used embedded parts. Although the pre-embedded fasteners used in the construction field have various forms, they are nothing more than composed of pre-embedded groove connection seats and pre-embedded ribs fixed on the connection seats. The connection seat used is C-shaped. The pre-embedded bars used are rebar and H-shaped steel. A large number of application practices show that this embedded fastener has a simple structure, poor mechanical properties, low bearing capacity, and uns...
