Post-cast strip inflatable arc angle rectangular flexible pipe side mold support construction method

Abstract

The invention relates to a post-cast strip side mold support construction method; an inflatable arc angle rectangular flexible pipe is arranged in a gap between an upper layer steel bar and a lower layer steel bar in the post-cast strip position; in inflation, the arc angle rectangular flexible pipe is extruded by the upper and lower layer steel bars so as to fill the gap caused by the steel bars;the soft pipe is inflated to form an air column so as to space the concrete; the cross section outer contour of the arc angle rectangular flexible pipe is an arc-shaped rectangular shape; the arc angle rectangular is a rectangular with four arc-shaped corners, and is an axially symmetrical and centrosymmetric geometric figure; the arc angle rectangular flexible pipe comprises a soft pipe outer wall and a soft pipe inner wall; the soft pipe outer wall cross section is the cross section contour of the arc angle rectangular flexible pipe, i.e., an arc angle rectangular; the soft pipe inner wallcomprises an upper pipe inner wall, a lower pipe inner wall and a common inner wall; the area enclosed by the upper pipe inner wall and the lower pipe inner wall is an air pump pressurization area; anarea enclosed by the soft pipe outer wall, the lower portion of the upper pipe inner wall and the upper portion of the lower pipe inner wall is an air connection area; the common inner wall has a constant pressure hole. The method employs the inflatable arc angle rectangular flexible pipe support, is good in moulding effect, high in construction quality, and high in efficiency.

Description

technical field [0001] The invention relates to a post-casting tape inflatable arc angle rectangular hose side form support construction method. Background technique [0002] With the rapid development of social economy in the new era, the development of my country's construction industry is also showing a trend of rapid development. In order to meet the needs of social development at the present stage, especially the needs of architectural functions and appearance, high-rise main buildings and low-rise skirt buildings are often connected together, and the scale of engineering buildings gradually tends to be super-long and super-large. The use of post-pouring tape construction technology can not only improve construction efficiency, improve building quality, but also improve appearance. At present, inflatable polyester fiber reinforced mesh + PVC coated hose (round) is usually used as side form support in post-casting belt construction technology, but with the increasing re...

Problems solved by technology

At present, inflatable polyester fiber reinforced mesh + PVC coated hose (round) is usually used as side form support in post-casting belt construction technology, but with the increasing requirements for the overall structural quality of engineering buildings in modern society High, the current construction technology is obviously unable to do what it wants, so in order to ensure the construction quality, improve the construction efficiency and reduce the construction cost, it is necessary to carry out technical innovation on the support of the post-cast belt side form
