Abstract

The invention discloses an inflatable mandrel supporting structure convenient to disassemble and assemble. The inflatable mandrel supporting structure can support an inflatable mandrel, improve the guiding and limiting effects on a protective cover, improve pouring convenience, enable the size and orientation of an inflation inlet to be consistent through the arrangement of the protective cover, reduce concrete pouring interference and improve appearance quality after forming. And meanwhile, the inflatable core mold is limited before pouring, floating displacement of the inflatable core mold during use is prevented, and the problems that the installation height of the core mold is not uniform, and the transverse distance is changed are solved.

Description

technical field

[0001] The invention relates to the field of building construction, in particular to an inflatable mandrel support structure that is easy to assemble and disassemble. Background technique

[0002] In the construction of hollow floors, there are many forms of fillers, such as light and high-strength materials, and inflatable mandrels. Because the inflatable mandrels can be recycled and reused, they are environmentally friendly and reliable, making them widely used in hollow floors. During the construction of the roof.

[0003] At present, there are mainly the following problems and shortcomings in the process of using the inflatable mandrel: in the construction of the hollow floor of the inflatable mandrel, in order to facilitate the recycling of the inflatable mandrel, it is often necessary to open an inflation port on the side of the inflatable mandrel, and place the inflatable mandrel The air pipe of the mold is uniformly protruded from this inflation port...
