Embodiment Construction

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

[0073] 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, the upper plate 4 covers the formwork 2, and is connected with the hidden rib 3 as a whole, which is characterized in that the prefabricated thin plate 1 is provided with at least one of the convex structure 5 or / and the concave structure 6 , Groove 10 is arranged on formwork 2. 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, 5 is a convex structure, and 6 is a concave structure. In t...

Abstract

The invention provides a combined reinforced concrete hollow floorslab, comprising a precast thin slab (1), a formwork (2), a hidden rib (3) and an upper slab (4), wherein, the formwork (2) is fixed on the precast thin slab (1); the hidden rib (3) is arranged between adjacent precast thin slabs (1) or formworks (2); and the upper slab (4) is covered on the formwork (2) and is connected with the hidden rib (3) into a whole. The invention is characterized in that at least one of a convex structure (5) or / and a concave structure (6) is arranged on the precast thin slab (1), and grooves (10) are arranged on the formwork (2). Therefore, the combined reinforced concrete hollow floorslab is applicable to various hollow floors, roofs, walls, foundation slabs and hollow bridges of cast-in-situ reinforced concrete or prestressed reinforced concrete, in particular to hollow flat slabs and ribbed slab floors.

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 200410002328.3, 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...
