Construction method for planting wall lacing bars after pre-burying of sleeve assemblies

Abstract

The invention discloses a construction method for planting wall lacing bars after pre-burying of sleeve assemblies. The method comprises the following steps of: (1) welding sleeves on straight bars of T-shaped mechanical anchorage ribs by using an electric welding machine to form sleeve assemblies, wherein screw threads are formed in the sleeves; (2) before pouring concrete onto a concrete structure, pre-burying the sleeve assemblies into wall lacing bar positions on the concrete structure according to design requirements, and screwing a plugging plastic bolt on the end part of each sleeve; (3) after concrete pouring on the concrete structure is completed, unscrewing the plugging plastic bolts on the end parts of the sleeves, screwing the wall lacing bars into the sleeves, tightening the wall lacing bars with the sleeves by using a spanner, checking qualification by using a torque spanner, and connecting the wall lacing bars and the sleeves into a whole through screw threads; and (4) during building of a later-built wall body, placing the wall lacing bars into mortar joints of the later-built wall body, and bonding the wall lacing bars together with the concrete structure reliably. The method is easy to operate; and the wall lacing bars can be placed into the mortar joints of the later-built wall body to be reliably bonded with the concrete structure.

Description

technical field [0001] The invention relates to a construction method for tying steel bars between a concrete structure and a rear wall in building construction, in particular to a construction method for pre-embedded sleeves and post-planting wall tying bars. Background technique [0002] The commonly used wall reinforcement construction methods in existing building construction are: [0003] 1 Pre-embedded in the concrete structure [0004] 1.1 Pre-embedded tension bars directly in the concrete structure [0005] In the method, in the construction process of the main concrete column wall, the tie bars of the post-built wall body and the concrete structure are embedded in the column wall concrete in advance, and the wall tie bars are removed after the concrete formwork is removed. During the chiseling process, this method has a large impact on the structural concrete surface and has a great impact on the structure, so it has been basically eliminated at present. [0006]...

Problems solved by technology

However, there are still defects in the poor grip between the expansion bolts and the concrete structure, the post-drilling disturbs the structure, and the structural steel bars are easily damaged during the drilling process.
