Abstract

An aerating moulding bed used for filling comprises an aerating air bag membrane (1) and a framework (2). The aerating moulding bed is characterized in that: the aerating air bag membrane (1) is a tubular member, and the framework (2) is arranged on the membrane wall of the aerating air bag membrane (1). Therefore, the aerating moulding bed is transported in an unaerated state and then is aerated and mounted on a construction site, thereby realizing convenient transportation and substantially reducing transportation cost; moreover, the framework arranged on the aerating moulding bed reinforces the mechanical property and the integrity of a moulding bed member, and increases the overall strength of the moulding bed member; meanwhile, a filling member has the characteristics of light deadweight, low cost, excellent shock resistance, simple, convenient and quick production and convenient transportation, etc., thereby achieving the aim of the invention. The aerating moulding bed is suitable to be used in hollow floor, roof, base slab, wall body and open frame bridge made of castinplace reinforced concrete, and is particularly suitable to be used in hollow beamless floor made of the castinplace reinforced concrete.

Description

(1) Technical field [0001] The invention relates to a pneumatic tire mold for filling. (2) Background technology [0002] At present, in the existing technology, the hole-forming components of cast-in-place hollow slabs are permanent mandrels, such as paper tubes, plastic tubes, metal bellows, and lightweight materials for mandrels. Small floor weight. For example, the patent number applied by the applicant is ZL99249755.8, and the name is a utility model patent named "fiber-reinforced thin-walled cylinder for filling cast-in-place reinforced concrete". It includes a hollow pipe body and a plug. The end is closed to form a thin-walled tube with a closed cavity, and at least one of the hollow tube body and the plug contains reinforcements such as fibers. The production mold of this kind of thin-walled pipe is complicated, and it is inconvenient to carry, and because of its fixed shape and large volume, it takes up a large amount of transportation space during transportation...
