. Pre-tensioned prestressed hollow plate beams are currently widely used. Used in various bridges, it has the characteristics of simple structure, clear force, easy production, transportation and installation. At the same time, hollow plate girders can be prefabricated into various shapes according to the design shape of the bridge to meet the different needs of various bridges. However, the original internal molds used in the production process were wood molds, bamboo molds, and steel molds. With the improvement of construction technology and the requirements for construction progress and cost, they can no longer meet the construction requirements.
.Rubber inflatable mandrel is a new type of support mold for pouring concrete. It is vulcanized by combining rubber and fiber fabric. It has high tensile strength, elasticity, softness and air tightness. Both ends are equipped with air inlets. Inlet and outlet and equipped with pressure gauge. After being filled with compressed air, concrete components that meet the design requirements can be prefabricated and cast-in-situ under various working conditions. This type of mold is particularly suitable for concrete pouring requirements for over-long and large-diameter hollow components and hollow components with special-shaped cross-sections. It is simple and easy to operate, light to install, easy to disassemble, and flexible in turnover. It has good aging resistance and has a wide range of applications. It can be used repeatedly for many times. Its advantages and strengths are also shown in reducing costs and accelerating construction progress. The hollow part of the bridge plate girder is drawn out using an inflatable rubber mandrel.
. Advantages of inflatable mandrels for precast concrete hollow slabs
The use of inflatable rubber mandrel technology can greatly speed up the precast construction progress of the entire slab beam.
Compared with the one-time investment of wooden formwork, the inflatable formwork can be used multiple times, and the construction is simple and convenient, saving a lot of material supply costs and the economic benefits are obvious.
The quality issues of precast hollow panels can be further ensured by controlling the quality issues of prefabricated hollow panels through strict core mold construction technology.
