Abstract

The present invention relates to a cavity mold-shell structural member which consists an upper plate (1), periphery side walls (2) and a lower plate (3), wherein the upper plate (1), the periphery side walls (2) and the lower plate (3) enclose a polyhedral hollow-cavity mould-shell structural member. At least one among the periphery side walls (2) and the lower plate (3) is made form light material (4) which is foam plastic, and the upper plate, periphery side walls and lower plate are all made from foam plastic. At least one among the periphery side walls (2) and the lower plate (3) is provided with at least a slice of a superposed layer. The cavity mold-shell structural member can be used for in-situ pouring reinforced concrete or pre-stressed reinforced concrete building cover, roof, base plate, wall, bridge and beamless building cover.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of September 15, 2003, the application number of 03157899.3, and the title of "A Cavity Formwork Component". (1) Technical field [0002] The present invention relates to a cavity formwork member. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. 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 the ...
