Problems solved by technology
However, after this formwork component is applied to the cast-in-place concrete hollow floor, the formed floor will inevitably be equipped with components such as various lines, and often needs to drill holes on the newly repaired floor, and it is difficult to install. Repair is very troublesome

Embodiment Construction
[0096] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0097] As shown in the accompanying drawings, the present invention comprises a reinforced concrete 1 and an open box 2. The open box 2 is wrapped in the reinforced concrete 1. The open boxes 2 are arranged alternately. Reinforced concrete upper plate 4, under which is cast-in-situ reinforced concrete lower plate 5, upper box plate 6 and surrounding formwork 7 to form an open box 2, characterized in that the surrounding formwork 7 is partially or completely compressible or / and stretchable Formwork 8, at least one side or two sides or three sides or four sides surrounding formwork 7 is the keel type formwork that keel 13 and formwork are combined into a whole, and vertical or horizontal keel 13 supports upper box plate 6. In each drawing, 1 is reinforced concrete, 2 is open box 2, 3 is cast-in-place reinforced concrete rib, 4 is upper plate of cast-in-pl...

A cast-in-situ concrete hollow plate comprises reinforced concretes (1) and opening boxes (2), the opening boxes (2) are packed in the reinforced concrete (1) and are separated-arranged, the cast-in-situ reinforced concrete ribs (3) are arranged between one another, the cast-in-situ reinforced concrete upper plate (4) is arranged thereon and the cast-in-situ reinforced concrete lower plate (5) isarranged thereunder, the upper box board (6) and the surrounding formwork (7) surrounds the opening box (2), and the invention is characterized in that the surrounding formwork (7) is the formwork (8) which is partly or totally compression-deformable or / and drawing-deformable. In this way, the surrounding framework is the framework which is partly or totally compression-deformable or / and drawing-deformable, the opening box is leaded to bear a certain impact deformation and is not easily damaged, and the formwork can be drawn according to the request, the construction application can be facilitated and the construction difficulty can be reduced, at the same time the opening box has the characters of simple structure, high strength, deformation resistance, excellent vibration resisting property, high production efficiency, low cost and the like, and the hollow plate is suitable for various building roofs, building covers, walls, base plates and hollow bridges.
Description
(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow 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 construction, whi...
