Description

{Cable Wall System using Reinforced Concrete Fixture}

The present invention relates to a cable wall system using a reinforced concrete fastener, and more particularly, to a cable wall system using a reinforced concrete fastener, wherein a plurality of vertical cables are provided in a normal direction of a glass panel, and a plurality of horizontal cables are provided perpendicularly to the vertical cable, The present invention relates to a cable wall system using a reinforced concrete fastener, in which the earth supports vertical and horizontal cables, pressurizes and fixes the glass panel, and has a cable fixture at one end of the vertical cable, and is fixedly embedded in a reinforced concrete slab.

Curb wall systems have been widely used to secure the wide view and openness of high - rise buildings, as the rise in land prices is accompanied by a rise in land prices due to the increase in urban population and the development of industrial society.

Especially, in the case of the ground floor, it is important to secure a wide view between the long and short sides of a lobby space such as a commercial facility or an exhibition space, so that a curtain wall system using a glass panel is generalized.

Meanwhile, the curtain wall system described above generally comprises an expensive aluminum-made transom, a mullion, and structural support members for structurally supporting the glass panel to fix the glass panel.

As a result, the overhead of the structure except for the glass panel causes the load to be burdened as well as the openability to deteriorate, and the workability is lowered, so that the air is lengthened and the construction cost is increased. Furthermore, it has been very difficult to apply it to a lobby space where it is important to secure a high floor height.

On the other hand, there is a rod wall system using a cable and a vertical round bar, but there is a non-economical feature that a structural support member such as a vertical round bar and a horizontal plate is still required, and the cable has a function of supporting a lateral load of the horizontal plate I was just doing it.

D.P.G. System (Dot Point Glazing System), however, in order to secure the floor height, a structure supporting member for supporting it must be accompanied with the same problem.

Accordingly, a cable wall system using only a cable and a junction was introduced. However, in the conventional cable wall system, a single horizontal cable and a vertical cable are combined using a joint and the glass is supported by using the joint.

Prior art documents using such a cable wall system are disclosed in Korean Patent Laid-Open Publication No. 10-2009-0027002 'Glass Wall Construction Clamp' (Published on Mar. 16, 2009), Korean Patent Registration No. 10- 1014645 'External glass supporting device for building exterior wall using cable' (registered on Feb. 08, 2011).

However, in the above prior art documents, the openness, the workability, and the economical efficiency can be secured by using only the cable and the junction. However, in order to fix the cable, a method of supporting the cable by fixing a bracket or anchor bolt to the steel frame can be used There was nothing.

It is difficult to apply this method to reinforced concrete structures that make up most of the buildings, and there is a disadvantage that it is not possible to apply the cable wall system to the reinforced concrete structures that have been installed.

In addition, the conventional cable wall system has structural limitations in application to the high floor height of the lobby space.

That is, even though the cable wall system can be applied to a space having a height of 9.2 meters or more, in this case, the diameter of the cable must be at least 100 mm, which results in inefficiency that is no different from conventional structural support members there was.

FIG. 1 shows a cable wall system according to the prior art, in which a single horizontal and vertical cable supports a glass panel via a metal support, and a bracket or anchor bolt or the like is fixed to a steel frame I had no choice but to use cable support.

Therefore, the prior art documents have been able to secure both openness, workability, and economy by using only the cable and the junction, but it has been difficult to apply to the reinforced concrete structure that occupies the majority of the buildings, and the reinforced concrete structure There is a drawback that the cable wall system can not be applied.

In addition, since the glass panel has to be pressed and fixed only by the tensile force, there is a structural limitation that it is difficult to apply to a high floor space such as a lobby space.

That is, if the cable wall system is applied to a space having a height of more than 9.2 meters, it is possible to implement but the cable must have a diameter of at least 100 mm. As a result, inefficiency there was.

At this time, the horizontal cable 20 is provided at right angles to each of the plurality of vertical cables 10, and can provide additional compression force while guiding the vertical cables 10.

Therefore, unlike the prior art in which only tensile force is exerted by using a single cable, it is possible to effectively pressurize the cable, and the cable can be formed to have a diameter of about 15.2 mm even in a space having a height of over 9.2 meters.

Thus, since the diameter of the cable can be reduced by about 85%, the cable material can be saved, the construction cost can be reduced, and only a plurality of cables and a joint support hole are required for supporting the glass panel G, It is possible to reduce the load burden on the structure except for (G).
