Problems solved by technology

This formwork member is in the cast-in-place concrete hollow slab, and the formed cast-in-place concrete hollow slab often needs to be installed with components such as air-conditioning ducts, and it is necessary to drill holes in the newly repaired cast-in-place concrete hollow slab, which is difficult to install. And it is very troublesome to repair; at the same time, it also reduces the clear height of the floor, affects the beauty of the ceiling, and increases the decoration cost

Embodiment Construction

[0081] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0082] As shown in the accompanying drawings, the present invention includes reinforced concrete 1, formwork components 2, the formwork components 2 are wrapped in the reinforced concrete 1, the formwork components 2 are arranged alternately, and there are cast-in-situ reinforced concrete ribs 3 between each other, and the formwork The component 2 includes an upper plate 4, a surrounding side wall 5, and a lower bottom plate 6. The upper plate 4, the surrounding side walls 5, and the lower bottom plate 6 form a closed polyhedral cavity formwork member, which is characterized in that the formwork member 2 is At least one air duct 7 is provided, and the air duct 7 runs through the surface of the formwork member 2 to form at least two ventilation openings 8 . In each drawing, 1 is reinforced concrete, 2 is formwork member, 3 is cast-in-place reinforced con...

Abstract

The invention is a cast-in-site concrete hollow slab, comprising reinforced concrete and form components, where the form components are wrapped in the reinforced concrete, and staggeredly arranged, cast-in-site reinforced concrete ribs are arranged between them, and each form component comprises top plate, peripheral side wall and infrabasal plate, which compose a closed polyhedral cavity form component, and it is characterized in that: the form component is provided with at least an air duct which runs through the surface of the form component so as to compose at least two intakes. And the invention is applied to cast-in-site reinforced concrete or prestressed reinforced concrete hollow floor systems, house covers, walls, foundation slabs 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, the cast-in-place concrete hollow slab is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor slab" pat...
