DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

Hereinafter, the technical structure of the present invention will be described in detail with reference to the preferred embodiments.

1 is a perspective view of a multi-joint type bracing structure of the present invention.

1, the multi-joint type brace structure 1 of the present invention includes a reinforcing frame 10 in the form of a frame-like quadrangular frame and a brace 30 (FIG. 1) having one end joined at the edge of the outer surface of the reinforcing frame 10 And an elastic pad 20 formed at a joint portion between the brace 30 and the reinforcing frame 10.

The reinforcement frame 10 is made of H-shaped steel and can be formed in a frame-like rectangular frame shape so that a conventional window frame is maintained in the internal space 11 when the conventional building is reinforced or installed in an opening of a new- And a window can be installed in the internal space 11 newly.

It is preferable that the reinforcing frame 10 is made of H-shaped steel having large second-order cross-sectional modulus and economical efficiency. Since the reinforcing frame 10 is formed in the shape of a quadrangular frame, the coupling between the vertical member and the horizontal member can be combined using various known joining methods such as welding and bolting.

Since the reinforcing frame 10 is formed by using H-shaped steel to form a quadrangular frame, a plate-like plate or a bent plate (not shown) is formed on each inner edge of the reinforcing frame 10 to connect the vertical surface and the horizontal plane of the reinforcing frame 10 Shaped reinforcement members 12 made of steel or the like can be combined to reinforce the respective corners.

Each of the four corners outside the reinforcing frame 10 is connected to a brace 30 and each corner of the reinforcing frame 10 between the brace angle 31 of the brace 30 and the reinforcing frame 10 engaging portion The elastic pad 20 is formed.

The elastic pad 20 deforms and absorbs the stress primarily when the elastic pad 20 is subjected to external stress such as compression or tensile at the opening of the building.

The elastic pad 20 can use various known products such as a high-damping rubber for absorbing vibration energy, and an elastomer remarkable in elasticity.

An elastomer is also called an elastomer, and is a polymer compound that has a property of stretching several times when pulled by an external force and returning to its original length when an external force is removed.

Figure 2 is a perspective view of a brace of the present invention, Figure 3a is a perspective view of a multi-joint link of a brace, and Figure 3b is a side cross-sectional view of Figure 3a.

2, the brace 30 includes a supporting angle 31 for engaging with the reinforcing frame 10, a corner angle 32 for engaging with a fixing channel 40 provided at the opening, and a supporting angle 31 And a multi-joint link 33 connecting the corner angle 32 with the corner angle 32.

3, a multi-joint link according to an exemplary embodiment of the present invention includes a plurality of bolt holes 331a are formed at least at one end thereof and bolt holes 331a are perforated, A bolt hole 332a is drilled at both ends and both ends of the bolt hole 332a are perforated so as to be spaced apart from each other on both sides of the length member 331 so as to correspond to the bolt hole 331a of the long member A viscoelastic member 333 disposed at an interval between the elongated member 331 and the overlapped member 332 and joining the elongated member 331 and the overlapped member 332, a bolt hole 331a, 332a And a bolt member 334 which penetrates through the elongated bolt hole 331a, the bolt hole 332a, and the viscoelastic member 333.

In this embodiment, a plate-shaped steel member having both ends of the elongated member 331 is used. A bolt hole 331a is formed in at least one end of the elongated member 331 so as to allow bolt connection with the overlock member 332. At this time, the bolt hole 331a is inserted into the bolt hole 331a of the bolt member 334 Diameter. When two or more length members 331 are used, bolt holes 331a should be drilled at both ends of the length member 332. [ The plurality of length members 331 are arranged in the same line with intervals so that the end portions of the bolt holes 331a are punched.

A plate-shaped steel member having both ends is used as the overlock member 332, and a bolt hole 332a for connection with the elongated member 331 is formed at both ends. The bolt hole 332a is formed to be larger than the diameter of the bolt member 334 and the bolt hole 332a of the overtop member 332 is inserted into the bolt hole 331a of the length member 331, Are disposed on both sides of the length member 331 at intervals. That is, the overlock member 332 is formed in such a shape as to be padded on both sides of the length member 331 spaced apart to connect the length member 331.

The point-ball-and-wire member 333 is disposed at a distance between the length member 331 and the overlapped member 332, and serves to primarily bond them.

As the viscoelastic member 333, a high damping rubber may be used. The high-damping rubber is prepared by adding additives such as fillers, vulcanizing agents, antioxidants and plasticizers to natural rubber and / or carbon black, and then vulcanizing the mixture at a predetermined temperature and a heat. At this time, the viscosity and elasticity of the highly damped rubber are controlled by adjusting the ratio of the additive added to the natural rubber or / and the carbon black. The high damping rubber has both elastic and viscous properties, and it provides additional stiffness when used as a vibration damping device in a material structure with good stability. It also increases the energy dissipation ability to control vibration of the structure by earthquake or wind It is a material suitable for the following.

The viscoelastic member 333 is bonded by applying any method known in the art, such as vulcanization bonding.

The viscoelastic member 333 is a means for connecting the elongated member 331 and the overlock member 332 and serves to absorb vibration energy by elastic deformation described later.

The bolt member 334 has a smaller diameter than the bolt holes 331a and 20a and penetrates through the elongated bolt hole 331a and the bolt hole 332a and the viscoelastic member 333 to form the elongated member 331, (332). The bolt hole 331a and the bolt hole 332a are made larger than the diameter of the bolt member 334, so that the bolt connection is not completely coupled. This is to induce the carbon and plastic deformation of the steel members after the carbon and plastic deformation of the viscoelastic member 333 described later.

The operation of the multi-joint link 33 of the present invention constructed as described above is as follows.

When the earthquake load or the wind load is transmitted to the structure, displacement and vibration occur in the structure. At this time, the viscoelastic member 333 of the vibration suppression device absorbs and damps displacement and vibration to secure stability and usability of the structure. That is, when a wind load or a weak seismic load is applied, the viscoelastic member 333 elastically resiliently resists resistance and absorbs and attenuates the horizontal load. The viscoelastic member 333 using the high-damping rubber can appropriately select the properties of the high-damping rubber material in order to stably perform the performance as the vibration damping member such as the horizontal stiffness, the vertical stiffness and the limit performance. The area can be adjusted.

When large horizontal loads exceeding the abrasive and plastic deformation capacity of the viscoelastic member 333 such as a strong earthquake load are generated, the steel members are plastically deformed to dissipate the energy. In the stage where the deformable capacity of the viscoelastic member 333 is already lost, the elongated member 331 made of a steel, the overlapped member 332 and the bolt member 334 are plastically deformed to absorb and attenuate energy.

4 is a schematic diagram showing the behavior of the multi-joint link of the present invention.

The multijoint link 33 of the present invention is characterized in that a plurality of connection rotary shafts are formed. The multi-joint link pads the overlock member 332 to the spaced apart portion while keeping the length member 331 apart, so that the connection does not occur in one portion but occurs in two portions. So that the deformation between the members may be made in the same direction as shown in Fig. 3A or in the other direction as shown in Fig. 3B. 3A, the viscoelastic member 333 and the steel members resist the clockwise twisting of both the upper and lower connection rotary shafts with respect to the overlapping member 332. In the case of FIG. 3B, Clockwise at the rotating shaft and counterclockwise at the lower connecting rotating shaft.

Unlike vertical loads such as fixed loads and working loads, wind loads and seismic loads can not predict their directionality, and dynamic loads continue to oscillate, so the behavior of the damping elements can not be expected in a certain direction. Accordingly, the multi-joint link 33 according to the present invention allows the vibration damping member itself to have various connection rotation shafts and to behave in various directions about the connection rotation axis with respect to unpredictable directionality and continuous vibration of the horizontal load.

5 is a perspective view of another embodiment of a multijointed link of the present invention.

In this embodiment, unlike the previous embodiment, the length member 331 is selected as a member having a multiaxial cross-section capable of providing multi-directional joining surfaces. For example, a rectangular steel pipe having a biaxial cross section provided by two pairs of joint surfaces shown in Fig. 5 may be selected. When connecting the overlock member 332 and the elongated member 331, the direction of the joining surface is changed in order with respect to the multi-axial direction of the end surface of the elongated member. That is, the upper Gusset member 332 shown in Figure 5 is composed of the connection in the first joint surface (a) about the first axis (A 1) of the elongated body (331) cross-section, of the lower Gusset member 332 Is connected at the second abutment surface (b) to the second axis (A 2 ) of the longitudinal member section. Such a connection in the axial direction enables the multi-axis behavior of the vibration damping member.

The multijoint link 33 according to the present invention is characterized in that the direction of displacement is not limited in a planar manner. That is, the joint between the members constituting the vibration suppression device does not correspond to one-directional displacement in a plan view but can be deformed into multiple axes, so that three-dimensional displacement behavior can be expected.

In general, the structural design for lateral loads is such that wind loads and seismic loads can not predict their directionality, so that a planar vibration device acting as a single axis is installed in various directions along the axial direction of the building according to the building shape.

The multijoint link 33 according to the present invention is advantageous in that it can be economically designed since it is not necessary to install a vibration suppression device in various directions on a building plane since one vibration suppression device can be operated with multiple axes.

In the above description and the example shown in the above, a rectangular steel pipe having a biaxial cross section is used as the long member 331, but the present invention is not limited thereto and a long member 331 having a multiaxial cross section of more than two axes can be used. If hexagonal cross sections with three axes or octagonal cross sections with four axes are used, it is possible to expect the displacement behavior for the 3-axis and 4-axis by joining while changing the joining faces in three directions and four directions respectively.

The link 33 of the brace 30 is formed such that one end and the other end of the link 33 are engaged with the outer edge of the supporting angle 31 and the outer edge of the corner angle 32 So that they have a shape cut in the same shape so that they can be easily combined.

At one end of the link 33, the supporting angle 31 is coupled to the other end of the corner angle 32 by various known methods such as welding.

Since the support angle 31 and the corner angle 32 are coupled to the corners of the reinforcing frame 10 and the openings respectively, the support angle and the corner angle are formed to be in the form of a straight line, 32 are formed with a plurality of anchor coupling holes 323 so as to be easily coupled to the anchor bolts 44 of the fixed channel 40. [

The link 33 allows the elastic pad 20 to deform and absorb the stress first when the building is subjected to external stress such as compression or tensile force so that the link 33 of the secondary bracing 30 absorbs the stress .

6 is a view schematically showing an opening reinforcing structure using the multi-joint type brace structure of the present invention.

As shown in FIG. 6, the opening reinforcing structure using the multi-joint type brace structure of the present invention reinforces an existing RC structure, such as a school, by reinforcing an opening made up of the column 8 and the beam or slab 9, A reinforcing frame 10 formed in the form of a frame made of H-shaped steel at the central portion of the fixed channel 40 constituting the fixed channel 40 on the outer side surface of the opening portion and a reinforcing frame 10 formed on the edge of the reinforcing frame 10, And the brace 30 are combined with each other, so that the multi-joint type brace structure 1 is assembled.

The brace 30 formed at each corner of the reinforcing frame 10 at the time of the occurrence of the stress F such as earthquake or the like can be obtained by providing the multi-joint type brace structure 1 with the fixing channel 40 provided at the opening portion, So that the tensile force T and the compressive force C are shared. That is, when the external stress such as compression or tensile is applied, the elastic pad 20 is deformed and absorbed firstly by the stress, so that the secondary bracing 30 absorbs the stress so that the structural stability can be induced. The fixed channel 40 can receive a shear resistance and exhibit high shear strength and shear stiffness to effectively increase the shear reinforcement effect.
