Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and a lower bottom 3. The upper plate 1, surrounding side walls 2, and lower bottom 3 form a polyhedral cavity formwork member, and the lower bottom 3 is formed from at least one surrounding The side wall 2 protrudes to form the pick plate 4, which is characterized in that a chamfer 5 is provided at at least one vertical corner of the cavity formwork member, and the vertical chamfer 5 intersects the pick plate 4 perpendicularly. In the accompanying drawings, 1 is an upper plate, 2 is a surrounding side wall, 3 is a lower bottom, 4 is a pick plate, and 5 is a chamfer. In the following drawings, those with the same number will be explained. As shown in Figure 1, the upper plate 1, the surrounding side walls 2 and the lower bottom 3 encl...

Abstract

The present invention relates to a hollow cavity form member for in-situ pouring concrete. It includes upper plate, peripheral side wall and lower bottom plate. Said upper plate, peripheral side wall and lower bottom plate are connected together and formed into a polygonal hollow cavity form member, its lower bottom plate is extended from at least one peripheral side wall and is formed into a cantilever slab. It is characterized by that at least one vertical corner place of said hollow cavity form member is equipped with a chamfer; said vertical chamfer is vertically crossed with said cantilever slab. Said hollow cavity form member is applicable to construction of cast-in-situ reinforced concrete or prestressed reinforced concrete floor, roof, wall body, foundation baseplate and bridge. In particular, it is applicable to construction of beamless floor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 4, 2003, an application number of 03143751.6, and a title of "a cavity formwork component for cast-in-place concrete". (1) Technical field [0002] The invention relates to a cavity formwork component for cast-in-place concrete. (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 ...
