[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 assembled by prefabricated reinforced concrete -shaped components or channel-shaped components, as shown in the patent No. ZL03248350.3 and a utility model patent titled "A Reinforced Concrete Assembled Floor". This kind of floor is composed of multiple reinforced concrete prefabricated components. The holes on both sides under the longitudinal rib of the component are connected with multiple reinforced concrete prefabricated components, and the groove-shaped concrete overhead slab with the opening facing downward is filled in the groove of the assembled floor slab to form a hollow floor slab, and then concrete is poured on the elevated slab to fill it up. Since the assembled floor slab has holes and steel bars on both sides under the longitudinal rib of the reinforced concrete prefabricated member, the assembled slab can bear two-way loads. However, when the assembled slab bears a large load, it is easy to produce two-way The difference in force and strain 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 ...
