Problems solved by technology

However, this kind of thin-walled box mold car shell component, as a whole thin-walled box component, takes up a lot of space during transportation, the quantity of each transportation is small, and the transportation cost is high, which undoubtedly increases the production cost of the thin-walled box and cast-in-place steel bars. The construction cost of the concrete hollow slab, therefore, the development of a new type of hollow member has been urgently needed

Abstract

A hollow member is composed of polyhedral external wall(1), cavity polyhedron(3), hinge(2) and T-shaped reinforcing rib(4). Said polyhedral external wall(1) encloses cavity polyhedron(3), intersecting line of said external wall(1) is hinge(2), parallel or intersected T-shaped reinforcing rib(4) are arranged on internal or external surface of said external wall(1). It can be used for various hollow plates of cast-in-situ reinforced concrete or pre-stressed reinforced concrete, hollow beamless building roof, basic baseboard, wall and bridges.

Description

(1) Technical field [0001] The invention relates to a hollow component. (2) Background technology [0002] At present, in the prior art, the hole-forming member of the cast-in-place reinforced concrete hollow slab is a permanent mandrel, such as paper tubes, plastic tubes, metal bellows, hollow form shells, and lightweight materials for mandrels. These tubular mandrels or hollow components are mainly considered to evacuate the concrete and reduce the weight of the hollow slab. 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...
