Embodiment Construction

[0071] The present invention will be further described below in conjunction with the drawings and embodiments.

[0072] As shown in the drawings, the present invention includes an upper plate 1, a surrounding side wall 2, a lower bottom plate 3. The upper plate 1, a surrounding side wall 2, and a lower bottom plate 3 form a closed polyhedral cavity mold shell member, which is characterized by the lower bottom plate At least one light trough box 4 is arranged on 3, and the opening of the light trough box 4 faces out of the lower bottom plate 3. figure 1 It is a schematic diagram of the structure of Embodiment 1 of the present invention. In the drawings, 1 is the upper plate, 2 is the surrounding side wall, 3 is the lower bottom plate, and 4 is the lamp slot box. In the following drawings, the same numbers have the same descriptions. Such as figure 1 As shown, the upper plate 1, the surrounding side walls 2 and the lower base plate 3 enclose a closed polyhedral cavity mold shell m...

Abstract

A permanent mold shell structural member consists of upper plate (1), periphery side walls (2) and lower plate (3), they enclose a polyhedral cavity structural member, at least one light-slot case is placed on lower plate, whose opening faces to lower plate and at least two cavities are arranged longitudinally on bar-like lower plate. It's convenient, fast, simple and efficient. It can be used for in-situ pouring reinforced concrete or pre-stressed reinforced concrete hollow building cover, roof, wall, base plate, hollow bridge and beamless building cover.

Description

[0001] This application is a divisional application of the invention patent application whose application date is October 27, 2003, the application number is 200310104258.8, and the name is "a permanent formwork member". (1) Technical field [0002] The invention relates to a permanent mold shell component. (2) Background technology [0003] At present, the cast-in-situ concrete hollow floor is a widely used floor structure, and the light permanent tire mold filled in it has a hollow tube and a cavity mold shell component. For example, the applicant applied for a patent number ZL99249798.1 on November 29, 1999, 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 board, the surrounding side walls, and the lower bottom enclose a polyhedral cavity. Another example is the applicant’s application number 01140106....
