Description

Functional support structure and construction method using the same, and construction structure constructed according to the construction method{Functional supporter and constructing method for a protrusion of construction structure using the same, and the construction structure constructed by the method}

The present invention relates to a functional support structure, a method for constructing a building structure using the same, and a building structure constructed according to the construction method, and more specifically, it is capable of effectively reinforcing the support structure in a portion without a protrusion, and is stable and stable. It relates to a functional support structure capable of easily constructing a building structure, a method of constructing a building structure using the same, and a building structure constructed according to the building method.

In general, in order to construct a reinforced concrete building, a frame is formed by reinforcing the reinforcing bar, and after installing a plurality of formwork on the outside of the frame, concrete is poured over a certain period of curing to construct the frame of the building.

At this time, when pouring concrete, formwork is used so that it can be cured to the external shape of the building frame.

The formwork is composed of a number of wood panels, which not only takes a lot of time to manufacture, but also has been damaged in the process of removing the formwork after the concrete curing is finished, so it cannot be reused. And once it was used, it could not be recycled.

Accordingly, in recent years, construction of high-rise and large-scale buildings is increasing, and large formwork (so-called "gang form") is used for concrete pouring of such high-rise buildings.

The gang form uses an inner formwork and an outer formwork made of large steel.

Republic of Korea Utility Model No. 20-365833 is a prior art showing the structure of a conventional gang form, the conventional gang form comprises a steel plate having a predetermined area and a gang form frame (Gang Frame) that reinforces the bottom surface of the steel plate. Crane hook for lifting, cage installed to allow the worker to work outside the formwork, safety rail to prevent the worker from falling, and installed to allow the worker to walk through the space of the cage Work scaffolding and the like are integrally installed on the outside of the gang form.

This gang form consists of a plurality of constructions to construct the outer wall of the building, and each gang form has a weight of about 3 to 4 tons, and is a large structure having a height of about 9m, which is a situation that is moved using a tower crane.

The gang form constructed as described above can be lifted using the tower crane installed at the construction site. Since the tower crane cannot continue to be used, the rest of the bolts, except the fixed bolt fixed to the lower side, are first released, and then the tower crane Hook the hook on the lifting hook and release the fixing bolt fixed on the lower side. Then, using the tower crane, the gang form is pulled upward.

On the other hand, the construction structure using such gang form is in a trend of changing from a flat planar structure to a three-dimensional structure having various protrusions in order to enhance the external design.

However, in order to form various protrusions on the building structure, due to the interference between the protrusions and the gang form, the existing method could not form the protrusions, and there was a hassle of constructing the protrusions separately from the construction of the building structure. In addition, a separate installation structure for forming the protrusions is required, and the workability is lowered and the construction cost is increased.

Accordingly, the applicant has registered the technology for the construction of the protrusions of the building structures through the Korean Patent Office Registration Patent Publication No. 10-1911415.

However, there may or may not be a protrusion in the building structure. In the case of a part without a protrusion, it is necessary to develop a technology to supplement it in that stable construction is possible only by supporting means.

Referring to these drawings, the present invention can effectively reinforce the support structure in the portion without the protrusion 130, so that it is possible to construct a building structure stably and easily, and the following gang form assembly 100 is applied for this purpose. .

That is, as for the construction of the wall 10 of the building structure, the gang form assembly 100 according to the present embodiment includes a plurality of alform units 110 and a gang form unit 120 disposed between the alform units 110. Can be.

Alform unit 110 serves as a framework for the construction of the wall 10 of the building structure. Alform unit 110 has a shape of a plate-shaped body, a plurality of stacked, installed in the vertical direction for the wall 10 construction.

A support piece 111 protruding in the horizontal direction is formed at an upper end of the alform unit 110. The height of the alform unit 110 may be made to be the same height as the height at which the protrusion 130 starts in the building structure. That is, the protrusion 130 is constructed starting from the end of the alform unit 110.

The alform unit 110 disposed at the bottom may be installed at a height of three levels from the ground on which the building structure is installed to secure space for the installation of the gang form assembly 100. Accordingly, a space for installation of the gang form assembly 100 is secured through the alform unit 110 installed up to the third floor level, so that an operator can easily perform the assembly and installation work of the gang form assembly 100.

The gang form unit 120 serves as a basic frame for constructing the protrusion 130 on the wall 10 of the building structure.

Gang-form unit 120 is disposed between the al-form units 110 in a state that can be moved up and down along the building structure. Inside the gangform unit 120, an installation space 125 for forming the protrusion 130 is formed.

The gang form unit 120 includes a reference gang form 121 and a protruding gang form 123. The reference gang form 121 extends upwardly and protrudes thicker than the thickness of the protrusion 130 at one end of the support piece 111. The reference gang form 121 extends and protrudes the wall 10 of the building structure constructed through the Alform unit 110 upwardly to be thinner than the thickness of the protruding part 130 so as to place the reference surface 131 on the wall 10 of the building structure. The space is partitioned for molding. The reference surface 131 means a point at which the protrusion 130 starts at the wall 10 of the building structure.

Through the cage 140 and the safety rail 150, the operator can easily move and safely perform the work for the construction of the protrusion.

On the other hand, the protruding gang form 123 can be moved up and down along the building structure through separate equipment. At this time, the equipment for moving up and down the protruding gang form can be implemented through a crane mainly used in a construction site.

Hereinafter, a brief look at the construction method.

First, a standard for installation of the gang form unit 120 is prepared by setting an outer surface area of the protrusion 130 to be formed in the building structure (S11).

The protruding gang form 123 is a structure that moves up and down along the building structure, and when its standard is set as the outer surface of the wall 10 of the building structure, a collision with the gang form unit 120 moving up and down is expected. Therefore, the outer surface area of the protruding portion 130 is used as a reference for the installation of the protruding gang form 123 of the gang form unit 120, so that the protruding gang form 123 of the gang form unit 120 does not collide with the protruding part 130 in the process of moving up and down.
