Embodiment Construction

[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1~4 As shown, the present invention provides a kind of closed water air bag 1 that can isolate high and low grade concrete, comprising:

[0028] A water-tight airbag sheath 11 sealed into a sealed cavity;

[0029] It is connected to the inflation valve 12 on the outer skin of the water-tight air bag.

[0030] Here, the water-closing airbag of the present invention can be placed between the concrete with high and low grades to be isolated. Since the skin of the water-closing airbag after inflation has a certain softness, it can fill the gap between the steel bar and the protective layer, and can effectively isolate the high and low grades. Concrete, convenient and reliable; the invention is simple to operat...

Abstract

The invention provides a water closing airbag capable of isolating high and low grade concrete and a mounting method of the water closing airbag. The water closing airbag can be placed between the to-be-isolated high and low grade concrete, due to the fact that the surface of the inflated water closing airbag has certain softness, a gap between a steel bar and a protective layer can be filled, thehigh and low grade concrete can be effectively isolated, and thus convenience and reliability are achieved. The water closing airbag is easy to operate, field manufacturing is easy, and the field operation difficulty of workers is lowered; the common quality problem of appearance color difference of the high and low grade concrete is solved, repair in the later stage is reduced, and the construction quality is improved; and the phenomenon of super pouring of the high grade concrete is effectively inhibited, and waste of materials is greatly reduced.

Description

technical field [0001] The invention relates to a water-tight air bag capable of isolating concrete with high and low marks and an installation method thereof. Background technique [0002] According to the structural design concept of strong columns and weak beams, when the concrete strength of beams, slabs and columns and walls is different, they must be poured separately, that is, the concrete of the beams and slabs must be poured after the column walls are poured. [0003] The traditional construction technique is to insert the silver-plated closing mesh vertically or obliquely into the beam to stop the flow of concrete. However, this process needs to cut the corresponding mesh according to the cross-sectional size of the beam before installing the silver-plated mesh, and pre-drill the holes according to the arrangement of the steel bars, and penetrate them at the same time as the stirrups when the steel bars are bound. [0004] Because the existing process itself is di...
