Construction method of horizontal construction joint stagnant water steel plate not penetrating stirrups at buttress column

Abstract

The invention discloses a construction method of a horizontal construction joint stagnant water steel plate not penetrating stirrups at a buttress column. The method comprises the following steps of arranging column ears on the outside of the buttress column connected to a basement outdoor wall, wherein the column ears are in a structure of a conversion channel used for the installation of the horizontal construction joint stagnant water steel plate, and a stagnant water steel plate is embedded and installed during the construction; directly bypassing and installing the a stagnant water steelplate next to the buttress column between the column ears, and then converting back to the original basement outdoor wall horizontal construction joint after passing the buttress column; using the column ears as the conversion path for the installation of the stagnant water steel plate at the buttress column to avoid the requirement of overall disconnection of the stirrups at a column densification zone when the stagnant water steel plate is installed at the buttress column; and after the installation of the stagnant water steel plate is completed, welding the stagnant water steel plate again,and after the installation of the stirrups in the later stage, carrying out the traditional construction of welding and sealing on the opening. The construction method of the horizontal constructionjoint stagnant water steel plate not penetrating stirrups at the buttress column abandons the traditional installation and construction method of the horizontal construction joint stagnant water steelplate at the "buttress column", is convenient and fast in construction, reduces the quality hazards, and effectively saves the construction cost.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method in which a waterproof steel plate does not penetrate through a stirrup at a horizontal construction joint at a buttress column. Background technique [0002] The waterproof quality of basement structural engineering has always been the focus of quality control in the construction industry, and the waterproof quality of basement exterior wall structures is the main content of each construction project management. Due to the construction needs of the outer wall of the basement, horizontal construction joints need to be set on the wall. How to do a good job in the construction of the horizontal construction joints to ensure that the backfilling of the underground construction in the later stage is completed, and there will be no pressure seepage at the construction joints of the outer wall will be the project quality management. The point. During...

Problems solved by technology

Problems in these two methods: 1. The stirrups in the encrypted area of ​​the "buttress column" need to be completely disconnected, and the stirrups must be welded after the water-stop steel plate is installed

The quality of the welded stirrups cannot be guaranteed

pose certain hidden dangers to the structural safety

2. Because the thickness of the common water-stop steel plate is about 3mm, whether
