Expanded-base pre-buried anchoring structure

Abstract

The invention discloses an expanded-base pre-buried anchoring structure which is a connecting part between a building main body structure and a decorative structure of an outer wall. The expanded-basepre-buried anchoring structure comprises a connecting plate, first bolt holes are symmetrically formed in two sides of the upper part of the connecting plate; second bolt holes are formed in the connecting plate and below the first bolt holes; third bolt holes are formed in the lower part of the connecting plate; bending bolts are arranged between the first bolt holes and the second bolt holes and at the third bolt holes; the end heads of the bending bolts are provided with flat gaskets, spring washers and nuts, the bending bolts matched between the first bolt holes and the second bolt holesare vertically arranged, and the bending bolts matched with the third bolt holes are horizontally arranged. At least four pipe holes which are evenly distributed are formed in the connecting plate, asleeve comprises a straight pipe part and a conical pipe part, the straight pipe part of the sleeve is inserted into a pipe hole and is fixedly connected with the connecting plate relatively, and theconical pipe part of the sleeve and the bending bolts are located on the rear side of the connecting plate. The expanded-base pre-buried anchoring structure is simple in structure, convenient to install, time-saving, labor-saving, safe and reliable, and working efficiency is improved.

Description

technical field [0001] The invention relates to an expanded bottom pre-embedded anchoring structure, which is a connecting part between a building main structure and a decorative structure of an outer curtain wall. Background technique [0002] All kinds of curtain walls around the main structure of the building, including glass curtain walls, aluminum curtain walls, stone curtain walls, etc. The plates that make up various curtain walls are installed on the decorative structure, and the decorative structure is fixedly connected to the main structure of the building through connecting parts and embedded parts. At present, there are two ways of embedding between the main structure of the building and the decorative structure, one is the way of pre-embedded panels, and the other is the way of pre-embedded panels. [0003] The method of pre-installing the embedded slab is to fix the embedded parts on the steel bars with iron wires or spot weld them on the stirrups after the be...

AI Technical Summary

Problems solved by technology

When the beam-column pouring concrete is tamped with a vibrating rod, it is easy to cause the stirrup to shift, resulting in the displacement or inclination of the pre-embedded slab, which cannot be tightly combined with the formwork, which may cause the following problems: 1. Pre-embedded When the deviation of the plate exceeds the welding range of the picking part, it is necessary to use steel plates to make up for the burial, and when the deviation is too large, it is necessary to reinstall the embedded plate; Compensation connection; 3. The pre-embedded slab and the formwork cannot be tightly combined, and the surface of the slab cannot be seen after the formwork is removed. It is necessary to use an electric pick to find the slab. When a high-rise building is looking for the slab, some concrete fragments will fall. To the ground, there is a safety hazard

[0004] The post-embedded slab method is a construction method in which holes are drilled after the beam-column concrete is poured and fixed with chemical bolts, which may cause the following problems: 1. The drilling positions of the chemical bolts are concentrated in the reinforcement-intensive area of ​​the beam-column. If the steel bar needs to be transposed and re-drilled, there are too many holes punched, which will cause harm to the original main structure, especially in the concrete compression area; 2. If the agent bolt holes are not cleaned during construction, it will cause sticking 3. The construction temperature of the agent is required to be -5~40 degrees Celsius. The lower the temperature, the longer the curing time, which is not conducive to winter construction in the north

4. The rear embedded plate is not connected to the main steel bar, which will affect the lightning protection effect
