Embodiment Construction
[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0064] As shown in the accompanying drawings, the present invention includes a prefabricated thin plate 1, a formwork 2, a hidden rib 3, and an upper plate 4. A formwork 2 is fixed on the prefabricated thin plate 1, and a dark space is arranged between adjacent prefabricated thin plates 1 or formworks 2. The rib 3 and the upper plate 4 cover the formwork 2 and are connected with the hidden rib 3 as a whole. It is characterized in that a connecting piece 5 is provided between the formwork 2 and the prefabricated thin plate 1, and is connected and fixed with each other. Part 5 is at least one of iron wire, weldment, bolt and ferrule. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a prefabricated thin plate, 2 is a formwork, 3 is a hidden rib, 4 is an upper plate, and 5 is a conne...

A combined reinforced concrete hollow floor comprises a prefabricated thin plate (1), a formwork (2), a concealed rib (3) and an upper plate (4). The prefabricated thin plate (1) is fixed with the formwork (2). The concealed rib (3) is arranged between the adjacent prefabricated thin plates (1) or the formworks (2). The upper plate (4) is covered on the formwork (2) and is integrated with the concealed rib (3). The invention is characterized in that a connecting piece (5) is arranged between the formwork (2) and the prefabricated thin plate (1) and is connected together for fixing. The connecting piece (5) is at least one component in iron wire, welding component, bolt and cutting sleeve. In this way, the hollow floor is suitable to be used for various hollow building roofs, building covers, walls, base plates and hollow bridge of the cast-in-situ reinforced concrete or prestressed reinforcement concrete.
Description
[0001] This application is a divisional application of an invention patent application with an application date of January 6, 2004, an application number of 200410002337.2, and a title of “A Composite Reinforced Concrete Hollow Floor Slab”. (1) Technical field [0002] The invention relates to a composite reinforced concrete hollow floor slab. (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, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many b...
