[0002] At present, reinforced concrete assembled hollow-core slabs can withstand two-way loads, have good overall performance, do not require on-site formwork, and are low in cost and convenient in construction. Assembled hollow-core slabs are usually prefabricated with reinforced concrete Type components or channel components, such as the utility model patent No. ZL03248350.3, titled "A Reinforced Concrete Assembled Floor". There are holes under the longitudinal ribs, and the steel bars pass through the holes on both sides under the longitudinal ribs of the prefabricated components to connect multiple reinforced concrete prefabricated components, and fill the grooves of the assembled floor slabs with trough-shaped concrete overhead slabs with openings facing downwards to form a hollow floor slab , and then pour concrete on the elevated slab to fill it up. This assembled slab has holes and steel bars on both sides under the longitudinal rib of the reinforced concrete prefabricated component, so that this assembled slab can bear two-way loads. However, this assembled slab When the load bears a large load, it is easy to produce two-way force and strain differences, which makes the assembly parts prone to cracks

Embodiment Construction
[0078] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0079] As shown in the accompanying drawings, the present invention includes a trough member 1, which is characterized in that the trough member 1 is a cast-in-place trough member, and slot fillers 2 are arranged at intervals in the groove of the trough member 1, and two adjacent ones are arranged Between the slot-filling parts 2 is the rib cavity 3 that forms the rib in the transverse groove, the rib cavity 3 in the groove communicates with the transverse hole 5 in the longitudinal rib 4 in the groove, and the rib cavity 3 in the groove communicates with the horizontal hole 5 in the longitudinal rib 4 The transverse hole 5 constitutes a transversely penetrating rib mold cavity 3 in the groove, and the groove-shaped member 1 and the groove-filling part 2 form an integral member in the groove. In each accompanying drawing, 1 is a groove-shaped member, 2 ...
