Problems solved by technology

The reserved holes of the bridge frame are usually relatively large, which leaves safety hazards such as workers stepping on the air, and in the later stage of fire prevention and sealing, after the installation of fire protection bags and fire boards, due to material reasons, it is very easy to integrate with other professional The cross construction is damaged, and there is a gap after the fireproof seal, which may affect the fireproof effect

Abstract

The invention discloses a finished bridge frame built-in fitting. The finished bridge frame built-in fitting comprises a bridge frame built-in fitting body, a bridge frame connecting piece and bent-corner steel plates, and the bridge frame built-in fitting body is formed by bending a steel plate to square; a plurality of connecting piece mounting holes are correspondingly formed in the two sides of the bridge frame built-in fitting body, fixed bolts penetrate through the connecting piece mounting holes, and the fixed bolts and the connecting piece mounting holes are welded and fixed; the bridge frame connecting piece is in a long strip shape and is provided with a plurality penetrating holes corresponding to the connecting piece mounting holes, and the bridge frame connecting piece is arranged on the fixed bolts through the penetrating holes in a penetrating mode, fixed through nuts, and used for being connected with a bridge frame; and the bent-corner steel plates are fixed to the circumferential side of the bottom edge of the bridge frame built-in fitting body, each bent-corner steel plate is provided with a plurality of formwork mounting holes, and the bent-corner steel plates and a structure formwork are fixed through timber bolts. The finished bridge frame built-in fitting is directly built in a concrete structure plate, reserved holes are not generated, the periphery of the bridge frame built-in fitting is reinforced concrete, fireproof blocking is not required to be conducted, and the fireproof effect is more reliable.

Description

technical field [0001] The invention relates to the field of pre-embedding of electrical bridges passing through structural plates, in particular to a pre-embedded part of a finished bridge. Background technique [0002] During the construction process of the construction project, when the cable bridge is installed through the floor, it is necessary to reserve a square hole in advance, and the bridge frame is installed through the reserved hole. Due to the reserved hole, the adjustment allowance for the bridge installation and the installation space for the bridge cover plate must be reserved. Therefore, the length and width of the square hole are usually 5-10cm larger than the bridge frame, and the gap between the bridge frame and the square hole needs to be filled with fireproof bag, fireproof mud and fireproof board. The reserved holes of the bridge frame are usually relatively large, which leaves safety hazards such as workers stepping on the air, and in the later stage ...
