Combined construction mould for dust-free room air return slab and combined construction method thereof

Abstract

The invention relates to a combined construction mould for dust-free room air return slabs and a combined construction method thereof. An upper mould and a lower mould are fixedly connected into a whole body in a locking way through a locking piece to form a cylindrical mould. A force application handle is arranged on a cylindrical surface in the upper mould and the opening end of the upper mould can be tightly covered by a cover. A base extends from the edge of the opening of the lower mould. The construction method is that the combined construction mould is arranged on a building template according to the configuration of the air return holes of the slabs, the base is firmly nailed on the building templates through iron nails, the cover of the upper mould is tightly closed before grouting and is opened after the grouted concrete is set, the locking piece is unlocked, the upper mould is pulled out through a suspension device and finally a knocking tool is used for knocking and applying force to the lower mould to strip off the lower mould. The combined construction mould can be repetitively used and can be conveniently fixed and removed, so the construction cost is saved and the construction period is shortened.

Description

technical field [0001] The invention relates to a construction mold for a clean room return air floor and a construction method thereof, in particular to a construction mold that is arranged on a building formwork, and after the grouted concrete is solidified, the construction mold is removed and recycled for reuse. Complete the slab with return air holes. Background technique [0002] In the process of building a clean room, tens of thousands of equidistant air return holes will be opened on the floor of the clean room to form a return air floor. [0003] Please refer to shown in Fig. 1, it is the construction schematic diagram of the concrete floor that the construction of prior art has return air hole, at first erect steel pipe scaffolding 4 earlier, and set up building formwork 2 on the erected scaffolding, to constitute layering After the construction formwork is set up, the return air hole construction mold 1 will be discharged, positioned and fixed. After the dischar...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned construction of the concrete floor with return air holes still has disadvantages. After the construction, the construction mold for the return air holes will be left in the floor, which cannot be reused and needs to be manufactured repeatedly. This not only increases the cost, but also has no environmental protection effect.

[0005] This shows that above-mentioned existing mode still has many deficiencies, is not a good design, and urgently needs to be improved
