Description

Mould for reserving small holes in concrete structure

Technical Field

The utility model relates to a formwork assembly, in particular to a mould for reserving small holes in a concrete structure.

Background

With the demands of production and living, building structure walls, columns and floors need to be provided with more equipment and facilities. In order to ensure the beauty of the building and the reliability of the structure, the first party and the design house increasingly adopt the form of reserving holes in the structure in the design process for later-stage fixed installation equipment. The traditional construction method for the reserved holes comprises the following steps: and adopting a wood template to form a mould, and using a crowbar to demolish in a violent manner after concrete is poured. By adopting the traditional construction method, the periphery of the die is usually not completely dismantled, the bottom die can not be dismantled even, the forming quality of the reserved holes is poor, and the installation precision of subsequent equipment can not be ensured seriously. The concrete with the reserved hole edges and corners is easily damaged by adopting the crowbar to violently remove the reserved hole templates, so that the appearance quality is affected, and the workload of secondary repair is increased. In addition, the embedded template is basically deformed and destroyed after being removed by the violence of the crowbar, and cannot be reused.

The template is a metal template, a fixedly connected square pipe is arranged on the inner side of the metal template, and the fixedly connected square pipe is connected with the metal template through a square pipe buckle.

The metal template, the fixedly connected square tube and the square tube buckle are all made of aluminum alloy.

The bottom die and the side die are formed by splicing three templates left and right, wherein the middle template is wide in upper part and narrow in lower part, and is connected with the adjacent templates through wedge-shaped seams.

And a steel wire limiting groove is formed in the outer side of the template and 1/3 of the position away from the die opening, and the pulling steel wire is embedded in the steel wire limiting groove.

All the side dies of the die are bound together by binding steel wires.

The utility model has the advantages and positive effects that: through adopting the structure that becomes zero with die block and side modeling, created the necessary condition for taking out of template, through adopting the pulling steel wire that sets up the inside traction on the template, for the template breaks away from concrete structure and provides the atress guarantee, make the template can thoroughly demolish smoothly under the assistance of crowbar, guarantee the construction quality of reservation hole, ensure the precision of later stage equipment installation. Meanwhile, the appearance quality of the reserved holes is better after the die is removed, the corner concrete cannot be damaged, the secondary repairing work is reduced, and the labor cost is saved. The method is simple in dismantling operation, free of damage after the template is dismantled, reusable, economical and environment-friendly.

Detailed Description

For a further understanding of the utility model, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings in which:

referring to fig. 1 to 6, a mould for reserving small holes in a concrete structure is composed of a bottom mould and side moulds, wherein the bottom mould and the side moulds are formed by splicing and fixedly connecting a plurality of templates left and right, each template is provided with a drawing steel wire 2, the drawing steel wires 2 are transversely wrapped on the back surfaces of the templates, two ends of the drawing steel wires extend into a mould cavity, and the middle part of the drawing steel wire is embedded on the back surfaces of the templates.

The bottom die and the side die are integrated into zero, necessary conditions are created for taking out the die plate, a pulling steel wire capable of being pulled inwards is arranged on the die plate, and a handle is provided for taking out the die plate, so that the die is convenient to disassemble, the forming quality of the reserved holes can be ensured, the die is not damaged after the die is disassembled, and the die can be reused.

In this embodiment, the template is a metal template, and a square pipe 3 is fixedly connected to the inner side of the metal template, and the square pipe 3 is fixedly connected to the metal template through a square pipe buckle 4. The die is convenient to disassemble. Furthermore, the metal templates, the fixedly connected square tubes 3 and the square tube buckles 4 are all made of aluminum alloy, so that the metal templates are light in weight and convenient to detach. The bottom die and the side die are formed by splicing three templates left and right, wherein the middle template is wide in upper part and narrow in lower part, and is connected with the adjacent templates through wedge-shaped seams. The templates are connected through wedge-shaped seams, so that the templates are convenient to tightly combine, and slurry leakage is avoided. And a steel wire limiting groove 1 is arranged at the outer side of the template and 1/3 of the position away from the die opening, and the pulling steel wire 2 is embedded in the steel wire limiting groove 1. The drawing steel wire is arranged at the position 1/3 of the die opening, is nearer to the die opening, is convenient to exert force, so that the template is separated from the concrete structure, and is nearer to the broadside of the middle template, and the template can be prevented from being damaged.
