Problems solved by technology

However, there is no reinforcing structure in the cavity formwork member, so the overall strength and rigidity of the cavity formwork member are relatively poor, and the cavity formwork member is prone to damage. After being applied to the cast-in-place concrete hollow floor, it is also Unable to participate in the force bearing and transmission of the hollow floor

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and lower bottom 3; The bottom 3 protrudes from at least one surrounding side wall 2 to form a pick plate 4, which is characterized in that at least one piece of stiffening rib 5 is arranged in the cavity formwork member, and the lower bottom 3 and the formwork 6 are superimposed to form a laminated lower bottom . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the upper plate, 2 is the surrounding side wall, 3 is the lower bottom, 4 is the pick plate, and 5 is the stiffener plate. 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 bottom 3 ...

Abstract

A cavity die shell member used in casting-in-place concrete includes a top plate, surrounding side walls and a bottom forming a polyhedron cavity shell brace member, among which, the bottom extends from at least one side wall to form a cantilever slab characterizing in setting at least one stiffening rib slab in the member. thus, the cavity die shell is strong and rigid, not easy to be broken and joints in the floor of tensile stress and transmission.

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...
