Problems solved by technology
However, there is no reinforcing structure in the formwork components in this floor slab, the overall strength and stiffness of the formwork components are relatively poor, and the overall strength and stiffness of the corresponding floor slabs are relatively poor. During the construction process of the floor slab, the formwork components are prone to damage. , and at the same time, it cannot participate in the force and force transmission of the cast-in-place concrete hollow floor

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 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 the formwork 2 is provided with reinforcing ribs 5, and the prefabricated thin plate 1 contains reinforcements 6. The prefabricated thin plate 1 It is larger than the formwork 2 fixed on it, protrudes outside the formwork 2, and is arranged close to each other to become a superimposed formwork of the hidden rib 3. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying ...

Disclosed is a combined forced concrete hollow floor, which comprises prefabricated thin plates (1), shutterings (2), invisible ribs (3) and upper plates (4), the prefabricated thin plate (1) is fixed with the shuttering (2), the invisible ribs (3) are arranged between adjacent prefabricated thin plates (1) or shutterings (2), the upper plate (4) covers on the shuttering (2), and is integrated with the invisible rib (3). The combined forced concrete hollow floor is characterized in that the shutterings (2) are provided with reinforced ribs (5), and the prefabricated thin plates (1) comprise reinforcements (6), are larger than the shutterings (2) fixed thereon, extend outside the shutterings (2) and are arranged abut against each other to form laminated formwork for the invisible ribs (3). the laminated slab is adapted to laminated building floor, roof, wall, base plate and bridge made by cast-in-situ reinforced concrete or prestressed reinforced concrete, especially hollow girderless floor and ribbed floor.
Description
[0001] This application is a divisional application of the patent application with the application number 2004100023353 and the application date being January 6, 2004, and the title is "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 buil...
