Embodiment 1

[0033] This embodiment provides a method for preparing a prefabricated ribbed concrete composite slab, the steps comprising:

[0034] S1. Small concrete blocks are poured in advance;

[0035] S2. Pre-pouring of truss concrete: if figure 1 As shown, a truss concrete mold is placed on the formwork surface; a certain number of poured small concrete blocks are placed on the truss concrete mold, and every two small concrete blocks are separated by a certain distance; poured in the truss concrete mold concrete;

[0036] S3. Pouring forming of laminated slabs: such as figure 2 with image 3 As shown, the laminated slab mold is placed on the other mold table and assembled; the steel mesh sheet is placed in the laminated slab mold; a certain number of suspension rings are bound on the steel mesh sheet, and the pouring completed steel truss concrete; concrete is poured into the composite slab mold to obtain the prefabricated ribbed concrete composite slab.

[0037] During the prod...

Embodiment 2

[0040] Such as Figure 4 As shown, this embodiment provides a prefabricated ribbed concrete composite slab, comprising: a base plate 1, a plurality of upper chord ribs 2 perpendicular to the base plate 1 and a plurality of suspension rings 4 fixed on the upper surface of the base plate 1; The upper chord rib 2 includes a plurality of web ribs 3 arranged between the bottom plate 1 and the upper chord rib 2 , and a plurality of rectangular holes are formed between the plurality of web ribs 3 .

[0041] Preferably, during the production and construction of the bottom plate 1, steel mesh is used to cast members instead of manual binding; and there is no reinforcement on all sides. If reinforcement is required, an additional level of steel is added, and the mold does not need to be opened during production. .

[0042] Preferably, the number of the upper chord ribs 2 is four.

[0043] Preferably, the number of web ribs 3 disposed between the bottom plate 1 and a single upper chord...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated ribbed concrete composite slab and a preparation method thereof. Background technique [0002] With the rapid development of the modern construction industry, more and more large-scale buildings are being built. As the main material of modern buildings, how to use reinforced concrete scientifically and rationally has become the focus of research in the construction industry. Prefabricated reinforced concrete laminated slabs are an irreplaceable part of modern buildings, but most of the existing precast concrete laminated slabs have difficulties in site construction, low factory production efficiency, and thick floor slabs. Therefore, there is an urgent need for a prefabricated ribbed concrete laminated slab and a preparation method thereof. Contents of the invention [0003] The object of the present invention is to provide a prefabricated ribb...
