Embodiment Construction
[0060] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0061]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 or / and the surrounding side walls 2. It is characterized in that at least one side raised edge 4 is a laminated layer raised edge, and the overlapping The layer flange comprises at least one prefabricated layer 5, and at least one of the upper plate 1 or / and the surrounding side walls 2 is or has a detachable movable part. In each accompanying drawing, 1 is an upper plate, 2 is a surrounding side wall, 3 is a lower bottom pl...

A cast-in-situs hollow floor plate comprises cast-in-situs reinforced bar concrete and a hollow cavity formwork component which comprises an upper board (1), a surrounding lateral wall (2), a lower bottom board (3), and a cantilever slab (4), wherein a sealed cavity is surrounded by the upper board (1), the surrounding lateral wall (2), and the lower bottom board (3), and the cantilever slab (4) extends from at least one outer side of the lower bottom board (3) or / and the surrounding lateral wall (2). The invention is characterized in that at least one side of the cantilever slab (4) is a cantilever slab with overlapping layers. The cantilever slab with overlapping layers comprises at least one prefabricated layer (5), and at least one of the upper board (1) or / and the surrounding lateral wall (2) is or is provided with a removable moveable component. The invention is suitable for the employment in hollow boards, hollow floors, roofs, foundation bottom board, walls, and hollow bridges of cast-in-situ reinforced concrete or inherent stress reinforced concrete, in particular to hollow floors without beams.
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-place concrete hollow 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 application n...
