Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0069] 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 at least one of the prefabricated thin plate 1 or the formwork 2 is provided with a fixed positioning member 5, and 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, and the reinforcement 6 in the prefabricated thin plate 1 extends into the inverted T-shaped cast-in-place co...

Abstract

A combined reinforced concrete hollow floor slab, comprising a prefabricated thin slab (1), formwork (2), concealed ribs (3), and an upper slab (4), the formwork (2) is fixed on the prefabricated thin slab (1), adjacent There are hidden ribs (3) between the prefabricated thin plates (1) or the formwork (2), and the upper plate (4) covers the formwork (2) and is connected with the hidden ribs (3) as a whole, which is characterized in that At least one of the prefabricated thin plate (1) or the formwork (2) is provided with a fixed positioning member (5), the prefabricated thin plate (1) is larger than the formwork (2) fixed thereon, and protrudes from the formwork (2) ) and are arranged close to each other to become a superimposed template of the hidden rib (3), and the reinforcement (6) in the prefabricated thin plate (1) extends into the inverted T-shaped cast-in-place concrete hidden rib (3) for anchoring. It is suitable for various hollow floors, roofs, walls, foundation slabs and hollow bridges of cast-in-place reinforced concrete or prestressed reinforced concrete.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of January 6, 2004, the application number of 2004100023156, and the 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 bu...
