Inflating mould for concrete filling

Abstract

The invention provides an inflation forming die used for concrete padding, comprising a flexible die wall (1) and an inflation plug-in module (2), wherein the flexible die wall (1) is closed to form a forming die. The invention is characterized in that the inflation plug-in module (2) is an inflation connector which can automatically close when a plug-in module is drawn out, and the flexible die wall (1) is provided with the inflation connector. Therefore, an inflation mandrel can be transported under a deflated state, and can be inflated and mounted at the construction field, thereby facilitating the transportation and greatly reducing the transportation cost; moreover, the inflation connector which is arranged on the forming die and can automatically close when the plug-in module is drawn out is advantageous to the prevention of gas leakage for the forming die on the position of the inflation connector; meanwhile, a padding component has the characteristics of light self-weight, low cost, good shakeproof performance, simple, convenient and quick production, convenient transportation and so on so as to achieve the aim of the invention, is applicable to a cast-in-situ concrete hollow floor, a cast-in-situ concrete roof, a cast-in-situ foundation slab, a cast-in-situ concrete wall body and a cast-in-situ concrete hollow bridge, in particular to a cast-in-situ concrete hollow flat slab.

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
