[0001] The present invention relates to a load bar for supporting a building exterior material, and more particularly to a load bar for supporting an expanded metal provided outside a structure such as a building to secure the structural strength and safety of the load bar, To a road bar composite structure using an outrigger and a tension cable, which is provided with a tension cable that transmits horizontal force to a building structure while preventing sagging, maintains the horizontal state of an outrigger, and transmits a vertical load to a fixed bracket .

A structure for protecting a vehicle or a person outside the structure or structure by shielding the structure from the outside is known, while an expanded metal is installed outside the building structure so that the silhouette of the structure can be seen from the outside.

However, some of the architectural structures have an hourglass-shaped structure with a mid-section, so they are inclined from the upper part to the lower part to the reverse side, and when they are installed as a cantilever for reinforcing a conventional frame, As a result, it is difficult to reinforce the steel frame (frame), and when reinforcing the steel frame structure, it is impossible to show the silhouette of the building neatly because the steel frame of a large size is exposed to the outside, There is a problem that a large and thick steel frame is exposed when viewed from the outside or looking inside, thereby damaging the outside view.

As another conventional technique, the following shows the installation structure of the dust net provided in the building.

A beam 100, an upper support 200, a wire rope 300, a dust net 400 and an unfolding means 500.

A plurality of lower support beams 100 are arranged at a predetermined interval on the outer wall of the building 1 having a predetermined height and one end of the wire rope 300 is fixedly coupled to the lower support beam 100. At the lower side of the lower support beam 100, The structure 10 is installed so that people using the inside of the building 1 through the first floor can safely move.

A rear end of the lower support beam 100 is fixed to the outer surface of the building through an anchor, and a wire rope 300 is fixedly coupled to the front end.

The upper support 200 includes an upper support beam 210 protruding outward from an upper portion of the building 1 such that the lower end of the wire rope 300 is connected to the lower support beam 100, Is fixedly coupled to the upper support beam 210, and the dust net 400 is provided in the lateral direction between the wiilpees 300. Reference numeral 220 denotes a wire winch.

However, in such a conventional dust-chamber mounting structure, the upper support beam is squeezed due to the load of the dust net itself, and when the external force such as strong wind is applied to the dust net, the load due to the external force can not be properly dispersed, The seismic structure corresponding to vibration of an earthquake or the like can not be provided, and the dust network is disadvantageously detached or damaged from the upper and lower support beams.

The buffer spring 1060 is provided between the upper frame 1020 and the elastic supporting portion 1040 and between the lower frame 1030 and the elastic supporting portion 1040 to attenuate vibration.

The guide portion 1080 protrudes from the upper and lower surfaces of the elastic supporting portion 1040 and the inner upper surface of the lower frame 1030 when the inner surface of the upper frame 1020 is inserted. And functions to prevent the buffer springs 1060 from being bent in the lateral direction while fixing and supporting the buffer springs 1060.

The sealing member 1070 is a rubber material having elasticity and inserted and fixed in a groove formed at one end of the upper frame 1020 and the lower frame 1030. The sealing member 1070 seals the side surface of the elastic supporting portion 1040, 1050 to prevent the outside air from flowing into the inside of the vibration damping portion.

The buffer rubber 1010 is provided between a flange provided at the lower end of the fixed column 620 and the upper frame 1020 and has a function of absorbing vibration by elasticity and restoring force of the buffer rubber. 5 to 15 parts by weight of zinc oxide, 3 parts by weight of stearic acid, 15 parts by weight of softening agent, 25 parts by weight of calcium oxide, 35 to 65 parts by weight of carbon black, 0.5 to 7 parts by weight of sulfur, And 4 to 9 parts by weight of a process oil. Since the buffered rubber having the above composition has excellent compressibility, heat resistance, weatherability, abrasion resistance, and excellent strength characteristics, And has a function of continuously maintaining the effect of the vibration damping while minimizing damage.

As to the operation of the vibration damping unit,

When a vibration such as a strong wind or an earthquake occurs, the structure vibrates, and the vibration is transmitted to the upper fixing part 600 so that the fixed support 620 also vibrates.

When the vibration is transmitted, the upper and lower frames 1020 and 1030 of the vibration damping unit also oscillate with a certain amplitude up and down. When the upper frame 1020 is moved downward by the vibration, 1050 flows into the lower cushioning space 1050 through the circulation hole 1090 formed in the elastic supporting portion 1040 and air resistance is generated and the vibration is attenuated by the air resistance.

In addition, the vibration energy can be further absorbed by the elasticity and restoring force of the buffer spring 1060 in addition.

When the lower frame 1030 is moved upward by the vibration, the function of attenuating the vibration of the upper frame 1020 occurs in the reverse order, and the function and effect of attenuating and absorbing the vibration are obtained.
