Problems solved by technology

Although this kind of floor slab can save a lot of formwork and speed up the construction process, because the formwork is separated from the prefabricated thin plate, and there is no reinforcement in the formwork, the overall strength and rigidity of the formwork are poor, and the formwork is prone to rupture The phenomenon brings inconvenience to the construction, so it is urgently needed to develop a new type of hollow ribbed floor slab

Embodiment Construction

[0058] The present invention will be further described below in conjunction with drawings and embodiments.

[0059] As shown in the accompanying drawings, the present invention includes a structural base plate (1), a cavity formwork (2), a cast-in-place reinforced concrete hidden rib (3), and a cast-in-place reinforced concrete upper plate (4), and is characterized in that the structural base plate (1 ) is connected with the cavity formwork (2) to form a polyhedron structure, and there are reinforcing ribs (5) on the cavity formwork (2). as attached figure 1 shown.

[0060] The present invention is also characterized in that the plate thickness of the structural bottom plate (1) is greater than the wall thickness of the cavity formwork (2), and there are reinforcing ribs (6) or reinforcing nets (7) in the cavity formwork (2) or structural bottom plate (1). ) or a combination of the two, the reinforcing bars (6) are steel bars, prestressed steel bars, steel wires, steel fiber...

Abstract

The floor slab includes bottom plate, hollow form board, in-situ steel bar reinforced concrete hidden ribs and in-situ steel bar reinforced concrete upper plate; and features that the structure bottom plate and hollow form board are connected to form polyhedral structure and that there are reinforcing ribs in the hollow form board. Owing to the structural bottom plate and hollow form board connected into one integral and the hollow form board with reinforcing ribs, the hollow member for the floor slab with hidden and dense ribs has high strength and rigidity and not easy to break, and the floor slab has simple structure, high strength, light weight and easy construction.

Description

(1) Technical field [0001] The invention relates to a hollow-core floor slab with concealed ribs. (2) Background technology [0002] At present, most buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity of the floor is poor, which is not conducive to earthquake resistance, and cracks in the gaps and water seepage often occur. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid and hollow). Although the problems of earthquake resistance and cracking have been solved, a large number of templates are used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construct...
