Abstract
A cast-in-situ concrete hollow floor slab, comprising cast-in-situ reinforced concrete, cavity formwork components, the cavity formwork components comprising an upper plate (1), surrounding side walls (2), lower bottom plate (3), and overhangs (4) , the upper plate (1), the surrounding side walls (2), and the lower bottom plate (3) form a closed cavity, and the raised edge (4) protrudes from at least one outer side of the lower bottom plate (3), and is characterized in that at least one side can be raised The edge (4) is the overhanging edge of the laminated layer, and the overhanging edge of the laminated layer includes at least one layer of prefabricated layer (5), and the cavity formwork member is also provided with internal corners (8), chamfers (9), grooves ( 10), at least one of pits (11), holes (12), boss modules (13), raised lines (14), male corners (15), and the closed cavity of the cavity formwork member is provided with At least one of stiffeners (16), stiffeners (17), and ribs (18). It is suitable for hollow floors, roofs, walls, foundation slabs and hollow bridges of cast-in-place reinforced concrete or prestressed reinforced concrete, especially for hollow beamless floors.
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...
