Beam column section high-low grade concrete air bag stubble blocking device and construction method thereof

Abstract

The invention discloses a beam-column section high-low grade concrete air bag stubble blocking device and a construction method thereof.The beam-column section high-low grade concrete air bag stubble blocking device comprises a stubble blocking air bag, an air bag connecting end, an inflation end, a double-end threaded pipe, an inflation pipe and a deflation inserting piece, and the top of the stubble blocking air bag and the bottom of the inflation end are installed in a threaded mode through the air bag connecting end; the inflation end comprises a reserved end and a quick connection end, the bottom of the reserved end is in threaded connection with the top of the air bag connection end, and the top of the reserved end and the bottom of the quick connection end are movably installed. According to the stubble blocking device, after a deflation pipe is inserted into the inner side of the top of the reserved end, a downward pressing plug at the bottom of the deflation pipe pushes a plugging piece on the inner side of the reserved end downwards, so that airflow in a stubble blocking air bag is discharged through an air hole, and after a clamping ball is clamped in a fastening groove b, a deflation insertion piece always extrudes the plugging piece to the bottom, and the deflation state is kept; and in cooperation with the arrangement of a quick-connection end for inflation, the construction efficiency of concrete air bag stubble blocking can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a stubble-blocking device and a construction method of a beam-column section with a concrete airbag of high and low marks. Background technique [0002] Concrete pouring with different strength levels in construction projects needs to set up stubble blocking, but the traditional stubble blocking tools are mostly combined steel frame, the installation is extremely cumbersome and inefficient, and the construction quality of stubble blocking is difficult to guarantee, and when the stubble blocking barbed wire is not installed When it is good, it will cause waste of high-grade concrete, which will increase the construction cost and affect the construction quality. Based on the above description, the complete isolation of concrete of different strength grades in the core area of ​​beam-column joints has gradually become a technical bottleneck for cost control and qual...

Problems solved by technology

[0006] The purpose of the present invention is to provide a device for blocking stubble with concrete airbags with high and low marks on beam-column joints and its construction method, so as to solve the problem of inflating the isolation airbags one by one before concrete pouring after the isolation airbags proposed in the above-mentioned background technology are filled into the building structure , due to the shielding effect of steel bar binding and erecting formwork, the air bag that has not been inflated and shriveled is in the building compartment, and its inflation port is difficult to be aligned with the external inflation tube for inflation, and it is also very easy to inflate or deflate. The problem of the port falling off caused the on-site construction personnel to repeat the inflation operation many times, or connect an inflation tube before filling each isolation air bag, but this method of inflation and deflation requires a lot of inflatable soft tubes to be erected on site. pipe, which prolongs the time-consuming construction of concrete airbag stubble blocking and reduces the construction efficiency
