Embodiment Construction

[0062] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0063] 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 ribs 3 and the upper plate 4 cover the formwork 2 and are connected with the hidden ribs 3 as a whole. It is characterized in that the four sides of the prefabricated thin plate 1 are provided with anti-crack structures 5 . 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 an anti-crack structure. In the following drawings, those with the same number have the same description. Such as...

Abstract

A kind of combined hollow building plank with reinforcing steel bar in it, comprises the prefabricate lamella, the mould hull, the hidden rib, the upper plank, the mould hull fixed on the prefabricate lamella, setting the hidden rib between prefabricate lamella and the mould hull ,and close together to them, overlaying the upper plank on the mould hull, and connect with the hidden rib for the integral whole, Its characteristic lie in setting crack defend construction on all sides of prefabricate lamella, thus, the strength of intersection which connect prefabricate lamella with cast-in-place concrete hidden rib is high. it's not easy to come forth of craze, even affecting the external appearance quantity of the building plank ceiling etc., in addition, the building plank still has the character of structure is simple, the strength is high, the anti- transform, anti- vibrate the function is good, construction convenience etc.

Description

(1) Technical field [0001] The invention relates to a composite reinforced concrete hollow floor slab. (2) Background technology [0002] 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 buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during cons...
