Embodiment Construction

[0069] The present invention will be further described below in conjunction with the drawings and embodiments.

[0070] 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 enclose a hollow body, which is characterized by the upper plate 1, the surrounding side wall 2 or at least one base of the lower bottom plate 3 is laminated with at least one laminated layer 4, the laminated layer 4 is laminated with the base as a whole, and at least one vertical groove 5 is provided on at least one peripheral side wall 2 of the cavity . 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, 4 is the laminated layer, and 5 is the vertical groove. In the following drawings, the same numbers have the same descripti...

Abstract

The invention is a kind of formwork component; it includes the upper board, around sidewalls, subjacent bottom board, all of which combines the hollow cavity, the character lies in: at least one base layer of the upper board, the around sidewalls and the subjacent board has at least a folding layer, and the folding layer and the base layer combines the integer. There sets at least a vertical slot at one or more around sidewalls of the cavity. Thus, the component is easy to be produced with a high efficiency; the cost is low, and there forms a pier, pole or strengthening rib in the slot, thus it improves the mechanism performance of building floor, It applies to hollow building floor, house floor, wall, base bottom board and hollow bridge which are poured bar concrete currently or prestressed bar concrete.

Description

(1) Technical field [0001] The invention relates to a mold shell component. (2) Background technology [0002] At present, cast-in-situ concrete hollow floor is a widely used floor structure, and the light permanent tire mold filled in it has hollow tubes and mold shell components. 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 plate, the surrounding side walls and the lower bottom enclose a polyhedral cavity. Another example is the applicant’s application number 01140106.0, publication number CN1356442, and invention patent application named "a cavity structure formwork for cast-in-situ reinforced concrete floor slabs" on November 23, 2001. The formwork component disclosed Including "the upper plate, the surround...
