Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0062] 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 edged by overlapping the raised edges. The edge includes at least one prefabricated layer 5, and the protruding length of the prefabricated layer 5 is the same as or different from that of the laminated layer. In each accompanying drawing, 1 is an upper plate, 2 is a surrounding side wall, 3 is a lower bottom plate, 4 is an overhang, an...

Abstract

The invention provides a cast-in-situ concrete hollow building floor which includes a cast-in-situ reinforced concrete 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) form a closed cavity and the rising edge (4) is extended from at least one side of the lower soleplate (3). The invention is characterized in that at least one side rising edge (4) is an overlapped layer rising edge which includes at least one layer of prefabricated layer (5); the surrounding side wall (2) with an openingat one side is provided with an outward turning edge and the prefabricated outward turning edge is a prefabricated layer. 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 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 slab. (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 applicat...
