Problems solved by technology

However, when the formwork components in this floor slab are produced, it is inconvenient to make, the production efficiency is low, and it is not convenient for assembly line production. Especially in the transportation and construction process, the formwork transportation is extremely inconvenient, and the overall formwork components occupy a lot The transportation space wastes a lot of transportation resources and increases the transportation cost, and the formwork is easily damaged due to bumps, extrusions and collisions during transportation, and the corresponding cost is high. Therefore, the corresponding cast-in-place concrete hollow slab has high cost, so , the development of a new type of cast-in-place concrete hollow slab is urgently needed

Embodiment Construction

[0075] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0076]As shown in the accompanying drawings, the present invention comprises a reinforced concrete 1, a prefabricated thin plate 2, and a cavity formwork member 3. The cavity formwork member 3 is arranged on the prefabricated thin plate 2. The bottom surface is flush, the cast-in-place reinforced concrete ribs 4 formed by cast-in-place reinforced concrete 1 are formed between the cavity formwork members 3, and the cast-in-place concrete laminated layer 5 formed by cast-in-place reinforced concrete 1 is formed on the cavity formwork member 3 , and connected with the cast-in-place reinforced concrete ribs 4, the cavity formwork member 2 includes an upper plate 6, surrounding side walls 7, and the upper plate 6 and surrounding side walls 7 form an open cavity formwork, which is characterized in that the cavity The cavity formwork member 3 has at least two ...

Abstract

Disclosed is a cast-in-situs concrete hollow slab, which comprises a reinforced-bar concrete (1) a prefabricated thin panel (2) and hollow shuttering members (3), arranged on the prefabricated thin panel (2), the lower floor of the prefabricated thin panel (2) is aligned with the floor of the cast-in-situ hollow slab, a cast-in-situ reinforced-bar rib (4) is formed between the hollow shuttering members (3) of the cast-in-situ reinforced bar concrete (1), a cast-in-situ overlapping layer (5) is formed above the hollow shuttering members (3) of the cast-in-situ reinforced bar concrete (1), and is connected to the cast-in-situ reinforced bar concrete ribs (4), the hollow shuttering members (2) comprise an upper board (6) and peripheral side panels (7), the upper board (6) and the peripheral side panels (7) encloses an open hollow form, characterized in that at least two of the hollow shuttering members (3) are pasted by prefabricated panels (8).

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur in the gaps, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during const...
