Embedded cylindrical nut anchor bed and use method thereof

Abstract

The invention relates to an embedded cylindrical nut anchor bed and a use method thereof. The embedded cylindrical nut anchor bed comprises a cylindrical body with a first inner threaded hole, wherein the front end part of the cylindrical body is provided with a positioning flange part which is provided with a positioning hole, and the rear end part of the cylindrical body is closed and is provided with a round hole connected with a structural reinforcing steel bar; or the rear end part of the cylindrical body is provided with a second threaded hole in threaded connection with the structural reinforcing steel bar. The use method comprises the following steps of: (1) arranging a plug screw into the inner threaded hole inside at the front end part of the embedded cylindrical nut anchor bed by using a tool; (2) connecting the rear end part of the embedded cylindrical nut anchor bed with the structural reinforcing steel bar; (3) jacking the positioning flange part on a template and fixing the positioning flange part on the wood template by using iron screws or self-tapping screws; and (4) pouring concrete into the wood template, detaching the wood template after the concrete is set, and when an external structure is in need of the embedded cylindrical nut anchor bed, arranging the external structure in the first inner threaded hole in a screw joint manner.

Description

technical field [0001] The invention relates to a pre-embedded cylindrical nut anchor seat and a using method thereof. Background technique [0002] In reinforced concrete structures, it is often required to reserve anchor bolts or anchor bars on its outer surface as a fixed or permanent structural connection of the facility. The current method is to pre-embed these anchor bolts or anchor bars from the drilled holes of the template before pouring concrete. The existing method has the following problems: (1) If the reserved position of the designed anchor bolt is inaccurate or the design needs to be changed for some reason, it must be changed by on-site cutting and welding, and the process is difficult; (2) When the anchor bolt When the bolts are fixed as temporary construction facilities, exhaust gas must be cut when they are used up, which is a cumbersome process and wastes materials; (3) The above-mentioned embedding requires drilling holes in the formwork, which will dam...

Problems solved by technology

The existing method has the following problems: (1) If the reserved position of the designed anchor bolt is inaccurate or the design needs to be changed for some reason, it must be changed by on-site cutting and welding, and the process is difficult; (2) When the anchor bolt When the bolts are fixed as temporary construction facilities, exhaust gas must be cut when they are used up, which is a cumbersome process and wastes materials; (3) The above-mentioned embedding requires drilling holes in the formwork, which will damage the integrity of the formwork, and grout leakage will occur during pouring, affecting the pouring of concrete (4) If the exposed anchor bolts or anchor bars need to be used later, they need to be protected on site, and it will affect the working environment
