Description

Anti-floating hollow mould box

Technical Field

The utility model relates to a sandwich floor on an empty stomach, concretely relates to anti hollow mould box that floats.

Background

The hollow sandwich floor slab is a composite hollow floor slab formed by adopting a prefabricated hollow mould box as an inner mould and burying the hollow mould box in a concrete floor slab. The hollow mould box is prefabricated by adopting light refractory materials, plays a role of an inner mould plate during construction, is left in the floor after the construction is finished to form the hollow sandwich floor with the reinforced concrete floor structure, so that the floor has higher economic index, better stress performance and longer fire resistance limit, and the sound insulation, heat insulation, vibration reduction, energy conservation and environmental protection performance of the floor are greatly improved.

The existing mold box is mostly prepared from gypsum, fiber gypsum or cement mortar, and is easy to float upwards in the process of pouring concrete. In order to solve the problem, the intellectual property bureau of China announces an inorganic flame-retardant composite box body with the announcement number of 201762874 for filling a hollow floor slab in 2011, 3, 16, a light solid box body and a hard shell layer covering the outer surface of the light solid box body, wherein a through cast-in-situ guide hole is formed in the light solid box body, and an anti-floating pull piece is arranged at the upper end opening of the cast-in-situ guide hole. The guide of cast-in-place concrete is carried out through the cast-in-place guide hole that begins to for it is closely knit to insert the vibrting spear to the concrete vibration, simultaneously, effectively releases the produced buoyancy of concreting in-process through cast-in-place guide hole, and fixes the box on the bottom plate muscle through anti superficial pull piece, further promotes anti buoyancy. Although the above-mentioned mode can resist floating to a certain extent, its anti-floating effect is still not good enough, and in addition, the interior of this box body is only supported by foam, and its strength is not enough.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide an anti hollow mould box that floats that anti is effectual, and intensity is high.

In order to solve the technical problem, the utility model discloses a following technical scheme:

an anti-floating hollow mold box comprises an upper mold box and a lower mold box, wherein the upper mold box and the lower mold box are detachably connected to form a cavity structure with a hollow middle part; an upper vertical cylinder and a lower vertical cylinder are respectively arranged in the cavities of the upper die box and the lower die box, and the end parts of the upper vertical cylinder and the lower vertical cylinder are connected to form a supporting part with an anti-floating hole inside. Therefore, after the lower die box is made of the fine aggregate concrete, the lower die box is heavy, has high anti-floating performance and good flame retardant performance, has the same components with floor concrete to be poured, and can be well mixed with cast-in-place concrete. The fiber net cloth layer and the wire netting arranged in the lower die box can effectively increase the strength of the lower die box and prevent the lower die box from deforming under pressure. The upper die box is made of gypsum, so that the weight is moderate, the flame retardant property is better, and the strength and the toughness of the fiber mesh fabric layer contained in the upper die box can be effectively improved. After an upper vertical cylinder arranged in the upper die box and a lower vertical cylinder arranged in the lower die box are connected, the compressive strength of the die box can be effectively increased, the supporting part formed by connecting the upper vertical cylinder and the lower vertical cylinder and the anti-floating hole formed by the hollow parts on the upper die box and the lower die box can effectively release buoyancy generated in the cast-in-place process, and meanwhile, the vibrating rod can be used for vibrating concrete under the die box after being inserted, so that the concrete is more compact.

Furthermore, the upper die box consists of a top surface and a lower frame body which is fixed on the outer edge of the top surface and is integrally formed with the top surface, and the lower die box consists of a bottom surface and an upper frame body which is fixed on the outer edge of the bottom surface and is integrally formed with the bottom surface; the upper frame body and the lower frame body are both rectangular, the upper end of the upper frame body is provided with an annular groove or a plurality of grooves at intervals, and the lower end of the lower frame body is provided with one or a plurality of socket-and-spigot bulges which are inserted into the grooves. Like this, go up the diaphragm capsule and fix through the mode of socket joint with lower diaphragm capsule to make and go up diaphragm capsule and lower diaphragm capsule junction and have better leakproofness, improve the wholeness ability of diaphragm capsule.

Further, the upper vertical cylinder and the lower vertical cylinder are fixed through sleeving. Like this, it cup joints fixedly with lower section of thick bamboo to stand on, and fixed mode is simple, convenient, and the leakproofness is good.

Furthermore, the lower end of the upper vertical cylinder and the upper end of the lower vertical cylinder are both provided with a rabbet, and the upper vertical cylinder and the lower vertical cylinder are fixedly inserted through the rabbet. Therefore, the upper vertical cylinder and the lower vertical cylinder are inserted through the tongue-and-groove, the sealing performance is good, and the connection is convenient.

Furthermore, the outer edge of the top surface of the upper die box is bent downwards, and the bottom surface of the lower die box is bent upwards to form an arc-shaped concave table. Therefore, after the die boxes are fully paved, a space with a narrow middle part and wide upper and lower ends is formed between the adjacent die boxes, and after concrete is poured, the concrete poured between the adjacent die boxes is mutually occluded with the die boxes, so that the die box has better stability.

Furthermore, the thickness of the middle part of the top surface of the upper die box and the bottom surface of the lower die box is larger than that of the outer side. Therefore, the middle part of the die box has the largest bearing force and has better compression resistance.

Furthermore, an anti-floating piece is arranged in the anti-floating hole and comprises an iron wire and a steel nail fixed at the lower end of the iron wire. Like this, can further improve the anti floating performance after the diaphragm capsule installation through anti floating, make the diaphragm capsule fix at the bottom of the slab muscle, prevent effectively that the displacement appears because of concrete lateral pressure at concreting in-process diaphragm capsule. And the steel nails and the iron wires are adopted as anti-floating pieces, so that the manufacturing cost is low. In addition, during the use, only need to fix the steel nail on the lower bolster, the ligature of iron wire upper end is on the board gluten to make the face muscle form the support pressure to the diaphragm capsule upper end, prevent the diaphragm capsule come-up, it is comparatively convenient to adopt above-mentioned anti-floating member operation, also can not influence concrete placement.

Compared with the prior art, the utility model discloses the anti hollow diaphragm capsule that floats that obtains has following advantage:

1. the upper die box is connected with the lower die box, and the lower die box is made of fine aggregate concrete, so that the self weight is large, the floating resistance is good, and the upper die box can be well fused with cast-in-place concrete.

2. After an upper vertical barrel arranged in the upper die box is connected with a lower vertical barrel arranged in the lower die box, the compression strength of the die box can be effectively increased, a supporting part formed after the lower vertical barrel is connected with the upper vertical barrel and can form an anti-floating hole with a buoyancy releasing effect together with through holes in the upper die box and the lower die box, and a vibrating rod can be inserted into the anti-floating hole to vibrate.
