Construction method of pull rod expansion screw bolt post embedding wall lacing wire

Abstract

The invention discloses a construction method of a reinforcing bar of a tie expansion bolt post-planted wall, which comprises the following steps: (1) after the completion of the construction of a concrete structure, a hole is drilled on the concrete structure according to the designing requirement; (2) the drilled hole is cleaned, a tie expansion bolt is inserted into the hole, and the wall reinforcing bar is inserted into a countersunk hollow bolt shank of the tie expansion bolt so as to lead the exposure of the anchor end to be more than or equal to 20mm; and (3) a nut of the tie expansion bolt is screwed so that pores between the wall reinforcing bar and the tie expansion bolt, as well as pores between the wall reinforcing bar and the concrete structure, are expanded into a whole. On the premise of ensuring quality, the construction method can utilize steel bar processing machinery to process the wall reinforcing bar, and the installation of the wall reinforcing bar requires only an electric drill or an electric hammer, a hand hammer, a brush and an open spanner, thus having simple operation.

Description

technical field [0001] The invention relates to a method for embedding tie reinforcement bars between a concrete structure and a rear wall during building construction, in particular to a construction method for tie rod expansion bolts rear wall reinforcement construction. Background technique [0002] The commonly used wall reinforcement construction methods in existing building construction are: [0003] 1 Embedded in concrete structure [0004] 1.1 Directly pre-embedded tension bars in concrete structures [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. This method has a certain impact on the force of the concrete structure during the chiseling process, especially on the visual quality; at the same time, the pre-embedded steel bars are prone ...

Problems solved by technology

The disadvantage is that there are currently no finished products on the market for sale, and at the same time, there is no on-site processing conditions. When ordering off-site processing, all the tension bars need to be manufactured and transported to the factory for processing, and then transported to the construction site for use. The transportation volume increases. , while the sleeve needs to be customized
