Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] 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 a pick plate 4, which is characterized in that at least one stiffener 5 is arranged in the cavity formwork member. figure 1It is a structural schematic diagram of Embodiment 1 of the present invention. 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 stiffener. In the following drawings, those with the same number have the same description. Such as figure 1 As shown, the upper plate 1, the surrounding side walls 2 and the lower bo...

Abstract

A cavity die shell member using a casting-in plate concrete includes a top plate, side walls and bottom forming a polyhedron cavity die shell component, among which, the bottom extends from a side wall to form a cantilever slab characterizing in setting at least one reinforcing rod in the component, therefore, the component is stronger and more rigid, not easy to be broken and bears and transmits stres with the floor.

Description

(1) Technical field [0001] The invention relates to a cavity formwork component for cast-in-place concrete. (2) Background technology [0002] 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 patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, and the name is called "combined concrete hidden rib floor cover plate" utility model patent, wh...
