Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] 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 prefabricated thin plate 1 is provided with a hanging part 5, a junction box 6, a light box box 7, and a wire pipe 8. At least one of the fire sprinkler head 9, the alarm 10, the water pipe 11, and the air outlet 12. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the drawings, 1 is the prefabricated sheet, 2 is the formwork, 3 is the hidden rib, 4 is the upper plate, 5 is th...

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 ribbetween 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, at least one of hanging piece junction box,light slot box, line tube, fire protection spraying cock annunciator(10),water pipe(11), and a place with a draught(12).Thus, no longer need to beat the bore to drill for fixing the above-mentioned accessories on the building plank, construction is very simple;the same time, it will not affect the external appearance quantity of the building plank ceiling, and repairing easy saved fitment expense.

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...
