Problems solved by technology

However, at the transverse corners of the formwork, where the cast-in-place concrete hidden ribs intersect with the cast-in-place concrete upper slab, the stress on the floor is more complicated, the stress is concentrated, and cracks are easy to occur, or even cracked and damaged.

Embodiment Construction

[0072] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0073] As shown in the drawings, the present invention includes a prefabricated thin plate 1, a formwork 2, a hidden rib 3, and an upper plate 4. Each prefabricated thin plate 1 is arranged horizontally at intervals, and a formwork 2 is fixed on the prefabricated thin plate 1. Adjacent prefabricated thin plates 1 or Hidden ribs 3 are arranged between the mold shells 2, and the upper plate 4 covers the mold shells 2 and is integrated with the hidden ribs 3. It is characterized in that all transverse corners of the mold shells 2 are set as transverse arcs Shaped corner 5, the cast-in-place concrete forms reinforcing ribs 6 at the intersection of cast-in-place concrete hidden ribs 3 and upper plate 4 at the transverse arc-shaped corner 5, and spacer braces 30 are arranged between formwork shells 2. figure 1 It is a structural schematic diagram of Embodimen...

Abstract

The invention provides a hollow floor of combined reinforced concrete, which comprises precast thin plates (1), shutterings (2), a hidden rib (3) and an upper plate (4). Each of the precast thin plates (1) is horizontally arranged at interval, the shutterings (2) are fixed on the precast thin plate (1), the hidden rib (3) is arranged between the adjacent precast thin plates (1) or the shutterings (2), and the upper plate (4) is covered on the shutterings (2) and is connected with the hidden rib (3) into a whole. The hollow floor of the combined reinforced concrete is characterized in that all transverse corner parts of the shutterings (2) are evenly arranged into transverse arc angles (5), a reinforced rib (6) is formed at a crossing part of the cast-in-place hidden rib (3) and the upper plate (4) by cast-in-place concrete, and an interval stay (30) is arranged between the shutterings (2). Therefore, the hollow floor of the combined reinforced concrete is applicable to various hollow floor slabs, roofs, walls, foundation base plates and open web bridge using cast-in-place reinforced concrete or pre-stressing reinforced 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 200410002334.9, 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...
