Description

Combined mould for reserving holes of cast-in-situ concrete floor

Technical Field

The utility model belongs to the building field, specific theory relates to a novel, economic, environmental protection's hole reservation modular mold.

Background

With the continuous development of the building industry, various holes need to be reserved on the main structure of the building. As is known, according to the conventional sleeve reservation mode, the reserved sleeve is not easy to fix in the installation process of the hole reserved sleeve, the sleeve is not easy to remove by a person before the initial setting and the intermediate setting of the floor concrete, the foot print can be left on the concrete floor surface when the sleeve is forcibly removed by the person, the sleeve is under the action of the lateral pressure of the concrete, and the hole deformation and the concrete structure disturbance can be caused by shaking and pulling out the sleeve; when the work and the seeds are crossed, contradictions are often generated; the sleeve is removed after the plate surface concrete reaches the strength, the binding force generated by concrete solidification prevents the sleeve from being pulled out, so that the consumption rate of the sleeve in construction use and turnover is too high, great material waste is caused, the removal of the sleeve is limited by time, and the quality of a hole finished product and the survival surface of a floor slab is not ensured. In view of the actual situation of the current construction, the utility model discloses a use of combined mould for reserving holes of cast-in-place concrete floors, the time limit of dismantling the reserved sleeve is solved, the combined mould is designed into T-shaped structure and can be fully combined with the concrete in the use process, the reserved holes finished product has good quality, the concrete contact surface is firmly combined in the secondary pouring process, the floor surface has no footprint, the manpower is reduced, and the combined mould can be repeatedly used; the quality of the hole finished product meets the design specification requirement.

SUMMERY OF THE UTILITY MODEL

The installation of reserving the sheathed tube for solving current building construction floor face is fixed, demolish the in-process and consume the scheduling problem to concrete slab protection and reduction manpower and materials, the utility model provides a think about unique, novel in design, simple structure, low in cost, use nimble, have enough to meet the need the novel practical modular mold of reserving of use, it is applicable to the hole reservation work of floor face in the building construction process.

In order to achieve the above object, the technical solution of the present invention is as follows:

the utility model discloses a combined mould for reserving holes of cast-in-place concrete floors, which comprises a flexible filling material, a hard material, thick rubber and plastic heat-preservation cotton, a sealing adhesive tape, a plurality of iron nails and binding wires; wherein,

the rubber-plastic heat-preservation cotton is wrapped by a hard material and wound into a T-shaped structure;

the sealing adhesive tape wraps the rubber and plastic heat-insulating cotton and is tightly wound;

the flexible filling material fills the inner space of the hard material, and the box sealing adhesive tape is wound to seal the upper opening and the lower opening of the combined die;

a plurality of nails are fixed around the combined mould, and the nails and the fixed openings of the upper opening of the combined mould are positioned on the same vertical line;

one end of the binding wire is bound on one nail, and the other end of the binding wire penetrates through the fixing port and then is wound and bound on the other nail.

The utility model provides an effective technical scheme and beneficial effect that cast-in-place concrete floor hole reserves with modular mold for solving present ordinary reservation sleeve pipe shortcoming and not enough are: 1. the structure is simple: the combined mould for reserving the hole of cast-in-situ concrete floor slab is mainly composed of PVC or other hard materials, flexible filling materials, a small amount of rubber-plastic heat-insulating cotton and a box sealing adhesive tape, and the concrete method is shown in the attached drawing of the specification. When the concrete floor slab surface is covered, the whole stress of the plastic heat-insulating cotton is relieved by the plasticity of the plastic heat-insulating cotton, the casing can be easily pulled out at any time after the concrete reaches a certain strength, the concrete at the hole edge is not damaged, and the problems that the hole is damaged by the removal of a common casing in the early preservation mode and the foot mark is left on the concrete slab surface are solved; 2. flexible use and simple turnover: the combined mould for reserving the holes of the cast-in-place concrete floor is simple to use and operate, and can play a role in integral fixation by utilizing the iron nails and the binding wires; the combined mould can be dismantled at any time according to the needs, and can be recycled after being dismantled; 3, low manufacturing cost: the combined mould for reserving the holes of the cast-in-place concrete floor slab has the advantages that the price of materials of the main body part is low, for example, DN150 casing pipes are taken as the example, the cost of one combined mould is 5 yuan, the finished product can be recycled for many times, the cost is saved compared with the existing direct pre-buried casing pipes, the quality requirements of the design specifications on the size and the impression of the reserved holes are met, the labor cost is reduced, and meanwhile, the construction progress of subsequent processes is greatly improved.

Detailed Description

The modular mold of the present invention will be further described by way of example with reference to the accompanying drawings.

Referring to fig. 1, 2 and 3, the combined mold for reserving the holes of the cast-in-place concrete floor slab mainly comprises: hard materials 2, such as PVC; thick rubber and plastic heat-insulating cotton 3, a box sealing adhesive tape 4, an iron nail 5, a binding wire 6 and a flexible filling material 1; PVC or other hard materials 2 are wrapped by the rubber and plastic heat insulation cotton 3 and wound into a T shape, the T-shaped structure is fully combined with concrete in the hole reservation construction process, and the hole leveling quality is good; the sealing adhesive tape 4 is used for wrapping the rubber and plastic heat-insulating cotton 3 to be tightly wound, the sealing adhesive tape 4 not only has a fastening effect on the rubber and plastic heat-insulating cotton 3, but also has a smooth outer surface and can reduce the grinding force of a joint surface with concrete.

Referring to fig. 1 and 3, after a floor face template 9 is erected, firstly, the inner space of PVC or other hard materials 2 is filled with flexible filling materials 1, secondly, the upper opening and the lower opening of a combined type mold are tightly wound and sealed by using a box sealing adhesive tape 4, mortar is prevented from being poured into a sleeve, the combined type mold is placed at a reserved hole in the drawing design, binding wires 5 are bound on nails 6, the nails 6 are fixed around the combined type mold, the positions of the nails 6 and a fixing opening 10 of the upper opening of the combined type mold are located on the same vertical line, the other ends of the binding wires penetrate through the reinforcing opening 10 to be tightly bound, and the binding and binding are firm.

Referring to fig. 3, after the floor slab concrete reaches a certain strength, the mold can be dismantled at any time as required; before the combined mould is not dismounted, the edge of the hole can be protected; and (4) disassembling the mould after the binding wires are untied, and easily pulling the combined mould out of the concrete floor surface by pulling the No. 18 iron wire 7 on the mould.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
