Description

Inner supporting die with arch structure Technical Field The invention belongs to the technical field of constructional engineering, and particularly relates to an inner supporting die with an arch structure. Background The arched girder structure revetment is the protection roadbed and prevents the important structure of soil erosion and water loss, along with the increasingly developing of facilities such as building, water conservancy, traffic, and the arched revetment is constructed with cast in situ concrete's mode mostly, among the prior art, the interior support mould commonality that uses is relatively poor, mould self weight is big, assembly operation is very complicated in the work progress, and disassemble back and transportation waste time and energy, in addition, when small batch (trial production) production, need make many sets of moulds, the cost is higher, it is also very inconvenient to use. Although the die products of the assembly type structures are improved, reasonable adaptation cannot be conveniently carried out according to actual working conditions, the die body does not form a system, stress is mainly concentrated on a key structure, damage is very easy to occur, service life and use reliability are low, self-locking cannot be formed due to the fact that all structural components cannot be mutually supported, and stability of the whole structure is not easy to guarantee. There is therefore a need for improvements over existing mold products. Disclosure of Invention In view of the above, the present invention is directed to overcoming the defects in the prior art, and provides an inner support mold with an arch structure.
