Anchor plate for construction and installation

Abstract

The invention provides an anchor plate for construction and installation. The anchor plate for construction and installation comprises a connecting hole, wherein the connecting hole is used for mounting a connecting bolt for a secondary connecting piece; the connecting bolt which is matched with the connecting hole when the secondary connecting piece is mounted comprises a head portion and a rod portion; the rod portion is matched with an inner hole of a locking sleeve; the diameter of the rod portion is smaller than the width of a narrowest position of a multi-node slot hole, so that the rod portion is suitable for freely sliding in the multi-node slot hole to adjust the position; after the locking sleeve sleeves the rod portion, the connecting bolt can be fixed in the multi-node slot hole along with the locking sleeve, and the locking sleeve and the connecting bolt are locked at a selected positioning hole site; and the head of the connecting bolt is clamped out of the positioning hole site. The connecting bolt can be placed in and taken out freely, conveniently and quickly, the position of the connecting bolt can be adjusted freely, conveniently and quickly, a mounting position can be quickly locked through the locking sleeve after the position is selected, workers can perform connection and fastening operation leisurely, welding reinforcement is not required, work intensity can be greatly reduced in a high altitude operation environment, and engineering quality is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anchor plate and a construction installation structure for construction installation, which is suitable for installation within the thickness of the concrete protective layer of beam bolts in various buildings and various engineering constructions. Background technique [0002] China has now become the country that builds the most curtain walls in the world. The building curtain wall is the outer protective structure that uses the main building as the carrier. The main load of the building curtain wall is the anchor structure connected with the concrete. It not only bears the weight of the curtain wall, but also bears a series of external forces such as wind resistance and earthquakes. Bearing capacity requirements, its flexibility and simplicity are also crucial. [0003] Most of the existing anchor plates directly weld the screws, washers, and nuts connecti...

Problems solved by technology

However, a deep space must be left on the steel surface of the concrete beam column for the T-shaped head anti-rotation block to sink and then rotate and pull out. The thickness of the existing groove-type embedded anchor is 25-35mm, forcing the surface of the steel bar to be concrete The protective layer exceeds the normal thickness (generally, the protective layer of the ribs is 20mm), causing problems such as squeezing the protective layer on the other side or reducing the ribs.

Moreover, the stability between the screw and the connecting hole is insufficient. After a certain number of building fluctuations (wind fluctuations, earthquake fluctuations), the gap between the screw and the connecting hole changes or the screw directly slips off, which has certain potential safety hazards.
