Inflation mandrel supporting structure convenient to disassemble and assemble

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...

Problems solved by technology

[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, which is convenient for air pressure inspection; because the air pipe of the inflatable mandrel may be poured and fixed during the concrete pouring process, resulting in the problem of increased cost of drawing the mold, so the protection of the air pipe is usually covered by the air pipe at present. The protective cover connected to the inflatable port is used to protect the air pipe during concrete pouring. After the concrete pouring is completed, the protective cover is removed, and the inflatable mandrel is taken out after the inflatable mandrel is deflated. At the same time, concrete is used to repair the protection The hole produced by the cover, perfect the follow-up process, in order to recycle the inflatable mandrel, hard plastic is often used to set the inflatable port as a protective cover, and the arrangement and fixing of the inflatable port is the control point of the pouring process, due to the relationship between the inflatable port and the protective cover The connection is a soft connection, which leads to the phenomenon that the protective cover is prone to tilting during the construction process, resulting in difficulties in pouring, poor quality of forming and perception, and waste of repaired concrete in the later stage; at the same time, there is a pressure difference during concrete pouring for different sizes of air-filling ports Different situations lead to the deformation of the air inlet due to the impact of concrete pouring; and because the buoyancy of the inflatable mandrel is relatively large when the concrete is poured, the inflatable mandrel floats during the construction process, resulting in construction quality that does not meet the requirements. If the mold is not installed with a fixing device, it is easy to have different installation heights of the core mold and changes in the lateral distance, which will lead to problems such as difficulty in concrete blanking, insufficient protective layer, and poor finished product effect.
