Prefabricated laminated slab cantilever frame pre-burying device, building component finished product and cantilever frame structure

Abstract

The invention relates to a prefabricated laminated slab cantilever frame pre-burying device, a building component finished product and a cantilever frame structure, is applied to the prefabricated structure construction process, and belongs to the field of building engineering structure construction. The prefabricated laminated slab cantilever frame pre-burying device is a metal rod piece, the bottom of the pre-burying device is pre-buried in the bottom of a laminated slab prefabricated pouring plate, the top of the pre-burying device extends out of the surface of a secondary pouring plate after the prefabricated laminated slab is installed, and the metal rod piece is perpendicular to the laminated slab. The device has the following advantages that 1, common safety and quality problems caused by a common assembly type structure laminated slab are thoroughly eliminated, and safety and quality defects are eliminated; 2, prefabricated molding is fast, the shaping size deviation is small,and the laminated slab with the pre-burying device is rapid and convenient to lift in place and is convenient to identify; 3, factory-like customized processing is realized, the manufacturing cost islow, the construction is convenient, and the safety is good; and 4, the construction of various subsequent processes after the structure construction is finished is facilitated, and the social and economic benefits are remarkable.

Description

technical field [0001] The invention relates to a pre-embedded device for a cantilever frame of a prefabricated laminated plate, finished building components, and a cantilever frame structure, which are applied in the construction process of the prefabricated structure and belong to the field of construction of building engineering structures.

Problems solved by technology

[0002] In the construction process of common high-rise building prefabricated structures, the cantilevered steel at the bottom of the cantilevered scaffolding and the fixing bolts of the floor structure plate are usually used to reserve bolt holes on the bottom plate of the laminated slab, and insert and fix the tension bolts after the formwork is removed. way, such as figure 1 As shown, there are the following two problems in the prefabricated laminated slab floor constructed by this construction method: 1. The anchor device of the I-beam anchorage section of the cantilevered scaffold runs through the reserved hole of the laminated slab, which is difficult for subsequent sealing and compaction and easy to seepage. The quality of water leakage is a common problem; 2. The plastic pipes with reserved holes running through the laminated slab are easily damaged during the transportation of the laminated slab. When the laminated slab is poured twice, it needs to be repaired and sealed, and it needs to be removed and sealed in the later stage. Waste A lot of labor and operation time
