Production method and production device of non-dismantling non-metal bottom plate fixed die laminated plate

Abstract

The invention relates to a production method of a non-dismantling non-metal bottom plate fixed die laminated plate and a production device for the non-dismantling non-metal bottom plate fixed die laminated plate by adopting the method. The method comprises the steps of bottom plate arrangement, cushion block arrangement, mesh arrangement, truss arrangement, truss fixing and the like, wherein the device adopts corresponding manipulators of an assembly line or other machines capable of executing related work to carry out operation of each step. The method and the device have the beneficial effects that the process is simple and convenient, the production period is short, the cost is low, the produced non-dismantling non-metal bottom plate fixed die laminated plate can be used as a permanentformwork for a floor and a roof, the cast-in-situ concrete layer is not dismounted after being consolidated, the production cost is low, the field construction is convenient, the formed floor has quality and texture meeting the habits of people, and the decoration is convenient.

[0002] Using the fixed formwork as the bottom formwork of the floor (including the roof) for concrete pouring can save the formwork disassembly process, which helps to simplify the construction process and improve construction efficiency. The existing floor formwork is a reinforced truss concrete formwork composite slab. It consists of a number of steel trusses arranged in parallel and a prefabricated concrete layer prefabricated at the bottom of the steel truss. The precast concrete layer is equipped with longitudinal steel bars and transverse steel bars according to the structural requirements. The cast-in-place concrete layer on the floor is consolidated with the precast concrete layer. However, in practice, this kind of reinforced truss-concrete fixed-form laminated slab has certain defects: first, the lower concrete layer is prefabricated in the factory, which not only greatly prolongs the production cycle, but also requires the addition of conventional mechanical processing equipment. In addition, a series of special equipment and facilities such as concrete mixing, pouring and curing have been added, which has greatly increased the floor area, greatly increased the load-bearing capacity requirements of the factory building, and seriously deteriorated the working environment, which in turn made the cost of this precast concrete Much higher than the cost of pouring concrete on site, and significantly increase other related costs such as transportation and storage; the second is to connect the reinforcement (usually the longitudinal and / or transverse reinforcement in the precast concrete layer is extended from the end or side ) is often hindered by the steel bars on the support (usually reinforced beams or walls) during on-site installation. Because the connecting steel bars are consolidated on the precast concrete layer, the exposed part is short and not easy to bend, so it is necessary to bypass the support It is very difficult to block the seat steel bars. In practice, the connecting steel bars often have to be cut off, which will seriously affect the connection strength. , will still cause a large amount of formwork removal work; Fourth, the bond strength between the prefabricated and cast-in-place concrete layers is significantly lower than the concrete strength of one operation, which affects the quality of the floor slab and is prone to cracks

In addition, when a metal plate is placed on the bottom of the precast concrete slab, although it is convenient or simplifies the related process, the workload of removing the metal plate is very large, and the removed metal plate usually has a lot of damage, which affects its reuse and causes certain damage. Waste, although the exposed steel truss reinforcement after removing the metal plate may not be visible from the outside after sealing, the sealing material cannot form an effective protective layer thickness, and the bonding strength between the sealing material and the surrounding materials is also low, which is easy to appear Problems such as surface peeling and steel corrosion exposure
