Inflation mould for concrete filling

Abstract

An aerating moulding bed used for concrete filling comprises an aerating member (1), wherein the aerating member (1) is a basin-shaped member; and a basin wall (2) is formed by an aerating bag. The aerating moulding bed is characterized in that: the inner wall or/and the outer wall of the aerating member (1) is/are provided with a framework (3), a pull belt (4) or a pull rope (5). The aerating moulding bed is convenient for transportation and substantially reduces 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 concrete 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 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, the upper plate, the surrounding side walls, and the lower bottom form a polyhedral cavity, and the upper plate, the surrounding side walls, and the lower bottom contain fiber reinforcements. Another example is that the application number applied by the applicant on November 23, 2001 is 01140106.0, the p...

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 slabs" patent application for invention, which includes "upper plate, The surrounding side walls, lower bottom, upper plate, surrounding side walls, and lower bottom form a polyhedral cavity formwork member, and the upper plate, surrounding side walls, and lower bottom contain reinforcements such as fibers or steel wire mesh. The production of such components is complex. , it is inconvenient to carry, and because of its fixed shape and large volume, it takes up a lot of transportation space during transportation
