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 cavity formwork member for cast-in-place concrete hollow slabs is urgently needed

Embodiment Construction
[0081] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0082]In the present invention, as shown in the accompanying drawings, the cavity formwork component 3 includes an upper plate 6 and surrounding side walls 7, and the upper plate 6 and the surrounding sidewalls 7 form an open cavity formwork, which is characterized in that the cavity formwork At least two of the components 3 are assembled by prefabricated panels 8, and there are at least two conjoined prefabricated panels in the prefabricated panels 8. The prefabricated panels 8 are assembled into an open cavity or a closed cavity. There are connecting pieces 9 between them, and at least one of the prefabricated panels 8 is provided with at least one of stiffeners 15 , stiffeners 16 or cables 17 . In each drawing, 1 is reinforced concrete, 2 is prefabricated thin plate, 3 is cavity formwork member, 4 is cast-in-place reinforced concrete rib, 5 is cast-i...

The invention provides a cavity shuttering member used for a cast-in-situ concrete hollow slab. The cavity shuttering member (3) includes an upper plate (6) and a surrounding side wall (7) that form an open cavity shuttering. The invention is characterized in that at least two of the cavity shuttering members (3) are pieced together by prefabricated slabs (8) which includes at least two connected prefabricated slabs; the prefabricated slabs (8) form an open cavity or a closed cavity and are connected together by a connecting piece (9), at least one of a reinforcing lever (15), a reinforcing ribbed sheet (16) or a cable (17) is arranged on at least one of the prefabricated slabs (8). In this way, the invention is applicable to constructing a hollow building floor, a house floor, a wall, a foundation mat and a hollow bridge with cast-in-situ reinforced concrete or pre-stressed reinforced concrete, and is especially suitable for the construction of a hollow flat slab floor.
Description
[0001] This application is a divisional application of an invention patent application with an application date of June 6, 2005, an application number of 200510075799.1, and a title of "a cast-in-place concrete hollow slab". (1) Technical field [0002] The invention relates to a cavity formwork component for cast-in-place concrete hollow slabs. (2) Background technology [0003] 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 pr...
