Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0060] As shown in the accompanying drawings, the present invention includes cast-in-place reinforced concrete, cavity formwork components, and the cavity formwork components include an upper plate 1, surrounding side walls 2, lower bottom plate 3, flanges 4, upper plate 1, surrounding side walls 2. The lower bottom plate 3 forms a closed cavity, and the raised edge 4 protrudes from at least one outer side of the lower bottom plate 3. It is characterized in that at least one side of the raised edge 4 is a laminated layer raised edge, and the laminated layer raised edge includes at least one layer The prefabricated layer 5 has a side wall 2 around the opening with an outer flanging edge, and the outer flanging edge is a prefabricated layer with a raised edge of the laminated layer. In each accompanying drawing, 1 is an upper plate, 2 is a surrounding sid...

Abstract

The invention provides a cast-in-situ concrete cored building floor which includes a cast-in-situ reinforced concrete member and a cavity shuttering member; the cavity shuttering member includes an upper plate (1), a surrounding side wall (2), a lower soleplate (3) and a rising edge (4); the upper plate (1), the surrounding side wall (2) and the lower soleplate (3) enclose a closed cavity, wherein the rising edge is protruded to at least one side from the lower soleplate (3). The invention is characterized in that at least one side rising edge (4) is an overlapped rising edge which includes at least one layer of prefabricated layer (5); the surrounding side wall (2) with an opening at one side is provided with an outward turning edge which is a prefabricated layer of the overlapped rising edge. The invention is applicable for constructing the hollow building floor, house floor, wall, foundation mat or hollow bridge with cast-in-situ reinforced concrete or pre-stressed reinforced concrete, and is especially suitable for the construction of hollow flat slab floor.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of October 21, 2003, an application number of 200310101176.8, and a title of "A Cavity Formwork Component". (1) Technical field [0002] The invention relates to a cast-in-situ concrete hollow floor. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application n...
