Embodiment Construction

[0137] The present invention will be further described below in conjunction with drawings and embodiments.

[0138] As shown in the accompanying drawings, the present invention is a concrete hole-forming mandrel, which includes a basin-shaped component 1. The basin-shaped component 1 is composed of a basin floor 4 and a basin side wall 5. The basin-shaped component 1 is also provided with a raised edge 3. A vertical groove 2 is provided on the wall 5 , and two basin-shaped components 1 are buckled together to form a closed cavity, which is characterized in that a hole tube 27 is arranged in the middle of the basin-shaped components 1 . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a basin-shaped member, 2 is a vertical groove, 3 is an overhang, 4 is a basin floor, 5 is a basin side wall, and 27 is a hole pipe. same. Such as figure 1 As shown, a raised edge 3 is also provided on the basin-shaped mem...

Abstract

The invention discloses a concrete pore-forming core mould. The concrete pore-forming core mould comprises basin-shaped members (1), wherein each basin-shaped member (1) consists of a basin bottom plate (4) and a basin side wall (5) and is also provided with a raised edge (3); the basin side wall (5) is provided with a vertical groove (2); the two basin-shaped members (1) are relatively closed to form a sealed cavity; and the core mould is characterized in that the middle part of the basin-shaped member (1) is provided with a porous pipe (27). Thus, the porous pipe can play a part in reinforcing the middle part of the basin-shaped member; moreover, when the core mould is applied to a floor, the concrete above and below the core mould can be connected integrally through the porous pipe by means of the pores, so the overall performance of the floor is improved; the basin side wall is provided with the vertical groove, which has an effect of structural reinforcement on the core mould per se, so the core mould is difficult to deform in the use; and when the pore-forming core mould is applied to cast-in-place concrete slabs, the aim of the invention is fulfilled. The core mould can be manufactured from materials such as plastic rubber, concrete, steel and the like, is suitable to be used in hollow floors, roofs, walls, base slabs and bridges of cast-in-place reinforced concrete or pre-stressed reinforced concrete, and is particularly suitable to be used in the hollow floors.

Description

(1) Technical field [0001] The invention relates to a concrete hole-forming mandrel. (2) Background technology [0002] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. 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 that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor slab" patent ...
