Prefabricated ribbed concrete laminated slab and preparation method thereof
The invention relates to a preparation method of a prefabricated ribbed concrete laminated slab. The preparation method of the prefabricated ribbed concrete laminated slab comprises the steps that S1,small concrete blocks are poured in advance; S2, truss concrete is poured in advance; and S3, the laminated slab is formed through pouring. The invention further relates to the prefabricated ribbed concrete laminated slab obtained through the preparation method. According to the preparation method of the prefabricated ribbed concrete laminated slab, as ribs are not exposed from four sides, the field construction difficulty is reduced; as a mold does not need to be punched, the repeated utilization rate of the mold is increased, and cost is reduced; upper chord ribs and web member ribs are poured and hardened in advance, the upper chord ribs and the web member ribs are inserted into a bottom plate after bottom plate concrete pouring is completed, steel bars in web members are anchored in the bottom plate, and therefore, the production difficulty is effectively lowered, and the production efficiency is enhanced; through the upper chord ribs and the web member ribs, the bending resistance of the bottom plate is effectively improved, and favorable conditions are created for support-free operation; in the field construction process, when a beam is a prefabricated beam, support-free operation is completely achieved; when the beam is a cast-in-place beam, only end supporting is needed, and supporting is not needed in the middle; and therefore, the difficulty and cost of the construction field are reduced; and as the prefabricated part is 50 mm in thickness and the cast-in-place part is 70 mm in thickness, the plate thickness is reduced, the clear height of a building is increased, the structural load is reduced, and the total concrete amount is reduced.
本发明涉及一种预制带肋混凝土叠合板的制备方法，步骤包括：S1、小砼块预先浇筑；S2、桁架砼预先浇筑；S3、叠合板浇筑成形。本发明还涉及一种由上述制备方法得到的预制带肋混凝土叠合板。本发明四面不出筋，降低现场施工难度；模具无需开孔，增加了模具的重复使用率，降低成本；上弦肋和腹杆肋预先浇筑硬化，在底板混凝土浇筑完成后，把上弦肋和腹杆肋插入底板，腹杆内的钢筋锚固在底板中，有效降低了生产难度，提高了生产效率；上弦肋和腹杆肋有效增大了底板的抗弯能力，为免支撑创造有利条件；在现场施工过程中，梁为预制梁时，完全实现免支撑，梁为现浇梁时，只需要在端部支撑，中部无需支撑，降低了施工现场的难度和成本；预制50mm、现浇70mm，减少了板厚，增加了建筑净高，降低了结构荷载，减少了总混凝土量。
