Problems solved by technology
[0003] In the past, wire mesh interception and partitions were used to intercept, but they could not be dismantled later, and the intercepted materials and components could not be recycled. The steel wire mesh and partitions were a one-time investment, and the cost was high; and due to the airtightness and strength of the steel mesh Limited, after the concrete is poured, the steel wire mesh is easily broken by the concrete, and the quality of the concrete construction cannot be guaranteed

The invention discloses a construction method for preventing mixed pouring of high-grade concrete and low-grade concrete, which comprises the following steps of: installing air bags, and after beam-column joint steel bars are bound, placing a plurality of uninflated air bags in gaps among the steel bars; inflating, namely communicating the air conveying branch pipes of the row inflating pipes with the inflating ports of the air bags one by one, and inflating the air bags through the air conveying main pipe of the row inflating pipes; pouring high-grade concrete, making the air bags expand after being inflated to compactly fill gaps between the steel bars, and then pouring high-grade concrete of the beam column joints; pouring low-grade concrete, after the high-grade concrete is condensed, air in the air bag is released, so that the air bag is shrunk and is separated from the high-grade concrete, the low-grade concrete is poured after the air bag is pulled out, and the low-grade concrete and the high-grade concrete are connected together; and recovering the air bag, cleaning and recovering the air bag for later use.
Description
technical field [0001] The invention relates to the technical field of a construction method for building anti-height mark concrete mixed pouring, in particular to a construction method for anti-height mark concrete mixed pouring. Background technique [0002] In building construction, columns, walls, beams, and slabs need to be poured with concrete of different strengths. When concretes of different strengths are mixed together, the structural performance is poor, which affects safety. Therefore, it is necessary to intercept when pouring concrete of different strengths. [0003] In the past, wire mesh interception and partitions were used to intercept, but they could not be dismantled later, and the intercepted materials and components could not be recycled. The steel wire mesh and partitions were a one-time investment, and the cost was high; and due to the airtightness and strength of the steel mesh Limited, after the concrete is poured, the steel wire mesh is easily broke...
