Description

External scaffold joint structure [

The present invention relates to an external scaffold joint structure, and more particularly, to an external scaffold joint structure that is coupled to a slab of a structure to enable the exterior finish work of the structure to be performed safely and efficiently.

Generally, the construction of the building is to construct the frame of the building by constructing columns, beams and slabs according to various structural systems such as steel frame and reinforced concrete. After completing the frame construction, various kinds of tiles, stone, Finishes are constructed to finish the exterior walls of the building.

In the case of such a finishing work, as a work is performed mainly from the outside of the building, installation of a temporary work bench including a work platform and a safety guardrail so that the worker can climb up the work and attach the finishing material or fix the finishing material .

A representative example of a hypothetical workbench is an external scaffolding structure. The external scaffolding structure includes a scaffolding, a pedestal, a safety guardrail, and the like, which are provided on the ground with underlaying hardware, and the height of the scaffolding column is gradually increased as the height of the building increases.

However, as the height of the scaffold increases, the external scaffold structure may have a problem such that the load caused by the scaffold, the safety guardrail, the worker, and the like gradually increases, and the high-scaffold column is buckled.

In addition, the horizontal distance between the scaffold and the slab of the building differs depending on the height, unlike the design, so that it is difficult to securely connect to the designed horizontal member or the like.

In addition, there is a problem that when a large load such as wind load acts on the external scaffold structure due to the unstable structure connecting the scaffold structure to the slab of the building, an accident occurs because the scaffold structure is separated from the slab.

Therefore, it is necessary to develop an external scaffolding structure that can maintain the rigidity even if the large scaffolding is applied even if the height of the external scaffold increases.

An outer scaffolding structure according to an exemplary embodiment of the present invention includes a first member 20 vertically penetrating a slab 10 of a building; A first engaging member (30) coupled to a lower side of the first member (20) and supported under the slab (10); A second engaging member (32) coupled to the upper side of the first member (20) and supported on the upper side of the slab (10); A second member (40) coupled to the first member (20) on the upper side of the second engagement member (32) and extending outward in the horizontal direction; And a third member 50 coupled to the outside of the second member 40 and installed vertically.

This embodiment improves the joining structure of the external scaffold, thereby making it possible to safely construct the finish work for installing various finish materials such as tiles, stones, and concrete panels on the outside of the building.

The first member 20 may be installed through the slab 10 of the building. The slab (10) of the building may be provided with a through hole through which the first member (20) can be inserted. After completion of the construction, the through hole may be filled with concrete and returned to a circular shape. The first member 20 may be formed as a hollow hollow tube, a square tube or the like. Further, the first member 20 may be formed of a hollow steel bar or the like. The first member 20 may be a screw formed on the outer circumferential surface or a screw formed on the outer circumferential surface. The first engaging member 30 or the second engaging member 32, which will be described later, can be welded or screwed to the first member 20.

The first engaging member 30 may be welded or screwed to the lower side of the first member 20. The first engaging member 30 may be integrally formed with the first member 20. The first engaging member 30 may be a bolt head integrally formed with the first member 20. A washer having a diameter larger than that of the bolt head may be provided on the inner side of the bolt head, that is, on the side of the slab 10. This washer can prevent breakage of the slab (10) by abutting the slab (10) with a large area. The first engaging member 30 can be coupled to the first member 20 and supported on the lower side of the slab 10. The first engagement member 30 may interact with the second engagement member 32 to be described later so that the first member 20 is firmly coupled to the slab 10. The first engaging member 30 may be a nut coupled with the first member 20 whose outer circumferential surface is formed by a screw. Also, a washer may be provided on the inner side of the nut, that is, on the side of the slab 10.

The second engagement member 32 can be welded or screwed on the upper side of the first member 20, that is, on the upper side of the slab 10. The second engaging member 32 can be coupled to the first member 20 and supported on the upper side of the slab 10. The second mating member 32 may allow the first member 20 to be securely coupled to the slab 10. The second engagement member 32 may be a nut coupled to the first member 20 or may be a nut and a washer.

A reinforcing member 60 having a predetermined thickness may be further provided between the slab 10 and the second engaging member 32. The reinforcing member 60 may be formed of a cast concrete. The reinforcing member 60 may be formed of a synthetic resin block, a precast concrete block, or the like. The reinforcing member 60 may be formed with a through hole through which the first member 20 passes. The reinforcing member 60 can increase the stability of the external scaffold effectively by corresponding to the external force acting on the slab 10 through the first member 20 by reinforcing the thin slab 10.

The adhesion preventive member 70 may be provided between the slab 10 and the reinforcing member 60 when the reinforcing member 60 is formed of cast concrete. The adhesion preventive member 70 may be formed of lattice-shaped vinyl or the like. The lattice-shaped attachment preventing member 70 allows the reinforcing member 60 to be appropriately attached to the slab 10 and can be easily removed after completion of the construction.

When the reinforcing member 60 is formed of a synthetic resin block or a precast concrete block, the reinforcing member 60 can be quickly installed and dismantled. In this case, a rubber plate 80 may be provided between the reinforcing member 60 and the slab 10. The rubber plate 80 prevents breakage of the slab 10 and enables the reinforcing member 60 to be closely attached to the slab 10 so that the coupling of the scaffold can be stably maintained during the construction.

The second member 40 can be engaged with the first member 20 on the upper side of the second engagement member 32. [ The second member 40 may be coupled with the first member 20 and extend horizontally outward. The second member (40) may be configured as a pair provided on both sides of the first member (20). The second member 40 may be formed of a round or rectangular long tube 42. A pair of circular or rectangular end pipes 44 provided on both sides of the first member 20 may be further provided on the pair of long pipes 42 of the second member 40. The end pipe 44 may be coupled to the long pipe 42 in a direction orthogonal to the long pipe 42 on the upper side or the lower side. The end pipe 44 may be welded or threaded to the long pipe 42. That is, the second member 40 may be composed of a pair of long pipes 42 and a pair of short pipes 44, and may be in contact with all four directions of the first member 20. A plurality of fastening holes may be formed in the pair of long-length pipes 42 along the longitudinal direction. A pair of short pipes (44) can be screwed into the plurality of fastening holes. That is, the end pipe 44 is selectively coupled to the required position in the plurality of fastening holes formed in the long pipe 42, so that the external scaffold can be easily installed regardless of the distance between the external scaffolding and the building.

A pair of closing rings 46 may be coupled to the long pipe 42 of the second member 40. A pair of closing rings 46 can be engaged around the long pipe 42. A pair of closing rings 46 can be screwed into a plurality of fastening holes formed in the long pipe 42. Accordingly, by adjusting the engagement position of the pair of closing rings 46, it is possible to cope with the distance between the outside scaffolding and the building.

The long pipe 42 of the second member 40 may be coupled with a closed ring 46 having a coupling hole formed at the center thereof. The first member 20 may be inserted into the coupling hole. One closing ring 46 can be screwed into a plurality of fastening holes formed in the long pipe 42. Therefore, by adjusting the engagement position of one closing ring 46, it is possible to cope with the distance between the outside scaffolding and the building.

The second member 40 may be disposed on the upper side of the second engagement member 32 or may be spaced apart from the second engagement member 32 by a predetermined distance. A circular tube (not shown) may be inserted into the first member 20 when the second member 40 is spaced from the upper side of the second engagement member 32 by a predetermined distance.

The third member 50, which is vertically installed at the outer end of the second member 40, can be coupled to the scaffold. The third member 50 may be coupled directly to the second member 40, or may be coupled to the second member 40 via a horizontal post. The coupling of the second member 40 and the third member 50 can be achieved by welding, threading, coupling using an associated coupling device, or the like. The lower end of the scaffold column, which is the third member 50, can be provided with an underlay iron that can support an external scaffold on the ground. Steel pipes, logs, H beams, etc. can be used for the underfitting. Therefore, the external scaffold can be more securely supported by being firmly supported not only on the slab 10 but also on the ground. In addition, a work footrest, a safety guardrail, and the like can be installed at a joint edge portion of the third member 50 and the second member 40. Thus, the worker can easily finish the exterior wall surface of the building from the outside scaffold.

The slab 10 of the building is provided with the first member 20 penetrating through the first member 20 in a direction perpendicular to the slab 10 of the building and the slab 10 is inserted into the slab 10 through the first coupling member 30 and the second coupling member 32. [ Since the first member 20 is firmly supported and the second member 40 is positionally adjustably connected to the first member 20, the distance between the outer scaffolding and the outer wall surface of the building can be adjusted, Since the external scaffold can be installed and coupled directly to the slab 10, even if the height of the external scaffold increases, it is possible to prevent the external scaffold from buckling because the load is not concentrated on the external scaffold. Therefore, It is safe and easy to finish the exterior wall of the building.
