3 and 4, a load reinforcing brace according to the present invention is a brace for reinforcing a support load by being coupled to an architectural structure. The brace includes a first reinforcement member 10 coupled between the structures to reinforce a support load, A second reinforcing member 20 coupled between the structure and reinforcing a supporting load to be coupled with the first reinforcing member 10 and a second reinforcing member 20 coupled to an end of the first reinforcing member 10, A first engaging member 30 for engaging the reinforcing member 10 to the structure and a second engaging member 30 for engaging the end of the second reinforcing member 20 to couple the second reinforcing member 20 to the structure. The first reinforcing member 10 and the second reinforcing member 20 have first support members 2 and 12 formed to have predetermined lengths and predetermined lengths, And the first support portion Wherein the first reinforcing member (10) and the second reinforcing member (20) are cross-coupled in an "X" shape, and the first reinforcing member The first and second facing parts 4 and 14 and the second facing parts 8 and 18 are formed on the supporting members 2 and 12 and the second supporting members 6 and 16, The first face-to-face engaging portions 4 and 14 and the second face-to-face engaging portions 8 and 18 are both formed by pressing and deforming the first and second supporting members 2 and 12 and 6 .

As shown in FIG. 17, the brace is a mechanical structure for reinforcing a supporting load by being coupled to a column 200 part for constructing a building.

The brace includes a first reinforcing member 10 for forming an overall "X" shape and a second reinforcing member 20 for overlapping the first reinforcing member 10.

A first engaging member 30 and a second engaging member 40 are coupled to ends of the first reinforcing member 10 and the second reinforcing member 20 and the first and second engaging members 40 And the brace is installed by being coupled to the column 200.

Here, the first reinforcing member 10 and the second reinforcing member 20 are formed by overlapping two supporting members, and the supporting members include a base portion 2-1 and an upstanding portion Quot; A " or "C"

The first reinforcing member 10 and the second reinforcing member 20 are formed by overlapping the two first support members 2 and the second support member 6 as described above to form one angled reinforcing member The support load can be increased as compared with the case.

Since the rising portion 2-2 having substantially the same shape as that of the base portion 2-1 is vertically formed, the rising portion 2-2 can be bent with respect to the bending load acting on the bottom portion 2-1, A very large resistance can be exhibited.

That is, when a load is applied to the base portion 2-1, the base portion 2-1 provides a resistance against the load by the thickness of the base portion 2-1. However, the rising portion 2-2 has a width The entire direction can provide a resistance against a load acting on the base portion 2-1.

The first and second supporting members 2 and 12 and the second supporting members 6 and 16 have first and second facing members 4 and 14 and a second facing member 8, Respectively.

The face-to-face engaging portions 4, 14, 8, 18 are formed to couple the first and second support members 2, 12 and the second support members 6, 16 at a predetermined distance from each other, The two reinforcing members 10 and 20 may be cross-coupled in the "X" form in the overlapped state.

Since the first and second support members 2 and 12 and the second support members 6 and 16 are formed with the same angle as the first support member 2, And the second support member 6 will be described as examples.

The face-to-face engaging portions 4 and 8 formed on the first and second support members 2 and 6 are both connected to the base portion 2-i of the first and second support members 2 and 6, 1 and 6-1 to form recesses in the base portions 2-1 and 6-1, and at the same time, protrusions are formed on the opposite sides.

Thus, when the two support members 2, 6 are in face-to-face engagement, the two face-to-face engaging portions 4, 8, which are formed to protrude from the facing side, Can be overlapped with each other.

The face-to-face engaging portions 4 and 8 are formed by deforming the base portion 2-1 of the angle using a metal. At this time, a fastening opening 4-1 for bolt fastening is formed on the face- Are simultaneously formed.

Thus, in the worksite where the load-reinforcing brace according to the present invention is to be installed, the support members 2, 6 in the state where the two face-to-face engaging portions 4, 8 are formed are overlapped with each other, -1), the reinforcing members 10 and 20 can be formed.

By forming the facing portion 4 by deforming the base portion 2-1, a kind of permanent plastic deformation is generated in the portion where the facing portion 4 is formed, so that a greater load bearing capacity is obtained.

Therefore, when an external force is applied to the reinforcing member 10, the face-to-face engaging portion 4 having a larger supporting force through plastic deformation as described above can provide a reaction force against an external force, .

In order to effectively provide a supporting force against an external force together with the gap keeping function, the face-to-face coupling portion of the support member is formed in a range of 1m to 1.2m (P).

If the period P is shorter than 1 m, the work for forming the face-to-face engaging portion 4 on the support member 2 becomes excessively large, thereby reducing the production yield of the support member 2, If the period P exceeds 1.2 m, the effect of increasing the support load by the face-to-face engaging portion 4 which is permanently deformed can not be sufficiently exhibited.

Therefore, by forming the face-to-face engaging portion 4 in the above-mentioned periodic range on the support member 2 formed of a steel material, the support member 2 can be used as a spacer, Can be optimized.

As shown in FIGS. 5 to 7, the concave portion of the base portion 2-1 formed by the face-to-face engaging portion 4 has a substantially rectangular shape in plan view and a substantially trapezoidal shape in a side end view.

Here, it is preferable that the side surface 4-3 of the trapezoid in the trapezoidal side end face is inclined to a range of 16 to 20 degrees with respect to the horizontal line.

In addition, in the trapezoidal space, each corner portion is preferably formed in a round shape instead of an angular shape.

As described above, the trapezoidal space edge portion is smoothly formed in a round shape, and the inclination of the side surface 4-3 is formed in the above range, thereby preventing stress from concentrating on the facing surface engaging portion 4, It is possible to prevent the base portion 2-1 from being broken by the mold when the engaging portion 4 is formed.

The width W3 corresponding to the bottom of the trapezoid in the concave space represented by the trapezoidal shape on the side end face is approximately 3 to 4 times larger than the width W4 corresponding to the upper side of the trapezoid .

In addition, the height d1 of the trapezoid in the trapezoidal concave portion may be in the range of about 0.5 cm to 1 cm.

Here, the width W2 of the concave portion is formed to be 2/3 to 4/5 of the width W1 of the base portion 2-1. Therefore, when the face contact portion 4 is formed, 1) can be prevented while maximizing the support load increasing effect by the plastic deformation.

6, protrusions are formed on the bottom surface of the base portion 2-1, and the protrusions of the two support members 2 and 6 are protruded from the base portion 2-1, Respectively.

By forming the protrusions 4-2 on the protrusions, when the two protrusions are abutted to each other, by increasing the frictional force by the protrusions 4-2 formed on the protrusions, the vibration externally applied is attenuated . ≪ / RTI >

The projections and depressions formed on the surface of the protrusions may be formed in a fine lattice shape in the form of a sperm pore.

Alternatively, as shown in Fig. 8, the shock absorbing member 70 may be disposed between the two protrusions to be brought into contact with each other, so that the shock absorbing member 70 may be configured to attenuate impacts or vibrations externally applied thereto.

In addition, it may be configured to more effectively attenuate impacts or vibrations by engaging the shock absorbing members of the synthetic resin material in a state where the bolts and nuts that couple the two face-to-face engaging portions 4 and 8 are disposed.

The impact absorbing members are preferably formed by compressing a synthetic resin such as polyurethane foamed.

On the other hand, in order to easily secure the engagement position of the two support members 2, 6 to be brought into contact with each other at the work site, the surface projecting from the face-to-face engaging portions 4, Concave and convex portions may be formed.

That is, a straight concave-convex portion formed along the direction perpendicular to the paper surface in FIG. 9 is formed on the surface of the protruding portion, and the concave portion formed on the protruding portion of the upper base portion 2-1 and the lower base portion 6-1, The two protrusions can be interlocked with each other by adjusting the width or the interval of the convex portions formed on the support portion, so that the coupling position can be sensed by sensing the two support members against each other.

That is, only when the two support members 2, 6 are disposed at the predetermined engagement position, the width or the interval of the concave-convex portion is formed so that the straight concave-convex portions formed on the two projections can be engaged with each other, And is configured to sense the binding position sensibly in the field.

Alternatively, the surface of the impact absorbing member 70 sandwiched between the two projections may have a straight concavo-convex portion formed thereon. By adjusting the interval or width of the concavo-convex portion, the position of the impact absorbing member 70 can be easily secured when the projections come into contact with the projections.

As shown in Fig. 10, by inserting the shock absorbing members 60, 70 and 90 between the base portions 2-1 and 6-1 of the two support members 2 and 6, And may be configured to attenuate external force and vibration applied to the member (10).

10, the No. 80 shock absorber is an impact absorbing member disposed at a portion where the connecting member 50 is engaged, the No. 90 shock absorbing member is an impact absorbing member disposed at a portion where the connecting member 30 is engaged, The impact absorbing member 60 is disposed between the connecting member 50 and the face-to-face engaging portion 4 and between the two face-to-face engaging portions.

The two support members can be slightly moved in the direction toward each other by the shock absorbing members 60, 70, 90 and the vibration applied to the reinforcing member 10 is attenuated.

The shock absorbing members 60, 70, 80, and 90 may be integrally formed, or may be divided and disposed between the support members.

In order to allow the bolts and nuts for fastening the two support members and the two support members constituting the reinforcement member 10 to flow, as shown in Fig. 14, the fastening openings 4 -1 may have a width slightly larger than the diameter of the bolt, and may be formed in the form of a long hole having a length longer than the width.

Thus, by allowing the bolt to flow somewhat in the fastening opening 4-1, the bolt is prevented from being broken even in the case of the vibration action by the earthquake.

The shock absorbing member 90 is disposed between the first reinforcing member 10 and the first engaging member 30 so as to be engaged with the first reinforcing member 10, It is possible to prevent the vibration transmitted from the pillars of the building from being transmitted to the reinforcing member 10.

The fastening opening 9 formed in the reinforcing member 10 and the engaging member 30 may also have a width somewhat larger than the diameter of the fastening bolt and may be formed as a long hole having a length longer than the width.

The first engaging member 30 and the second engaging member 40 are respectively fitted to end portions of the first reinforcing member 10 and the second reinforcing member 20 and the first engaging member 30 And the first reinforcing member 10 and between the second engaging member 40 and the second reinforcing member 40 may be formed at predetermined intervals.

Thus, the coupling members 30 and 40 can be slightly moved in the axial direction of the bolt while being fitted to the ends of the reinforcing members 10 and 20, so that the vibration from the coupling members 30 and 40 It can be prevented from being directly transmitted to the reinforcing members 10 and 20.

Fig. 11 is a perspective view of the load-reinforcing brace according to the present invention with a " c "cross-sectional shape, and Fig. 12 is a perspective view of a support member used for the brace.

13, the coupling member may further include a first coupling plate 30 formed in a plate shape and a second coupling plate 35 coupled in a direction perpendicular to the coupling plate 30 have.

The second engaging plate 35 and the pillar 200 can be stably held in a wide surface contact state by providing the second engaging plate 35 in addition to the case where only the first engaging plate 30 is provided. .

As shown in Fig. 16, the second engaging plate 35 may be formed of a pair of "a " cross-sectional shape angle members.

As a result, by engaging with the first engaging plate 30 in a state where an impact absorbing member (not shown) is disposed between a pair of the second engaging plates 35, 2 coupling plate 35. In this case,

Alternatively, the second coupling plate formed of the angle member may be formed with an elongated fastening opening 42 having a width slightly larger than the diameter of the fastening bolt and a length longer than the width of the fastening bolt, By allowing the first engaging plate 40 to flow somewhat between the two second engaging plates 35 by engaging the plate 40, the vibration from the second engaging plate 35 is attenuated, And may be configured to be transmitted to the first coupling plate 40.

3 and 4, the first supporting member 12 and the second supporting member 16 of the second reinforcing member 20 are divided around the first reinforcing member 10, The first support member 12 and the second support member 16 formed may be coupled via the connecting member 50. [

The connecting member 50 is disposed between the first supporting member 2 and the second supporting member 6 of the first reinforcing member 10 and the surface of the connecting member 50 is provided with a concave / .

Thus, when vibration is applied in a state where the connecting member 50 is engaged with the supporting members, the friction force is increased by the concave-convex portion so that the vibration can be attenuated for a while.

A connection opening 52 in the form of an elongated hole through which the bolts for coupling the first support member 2 and the second support member 6 of the first reinforcing member 10 can be slightly moved is formed in the connecting member 50).

Thus, the bolts for coupling the first and second support members 2 and 6 are configured to be able to flow somewhat inside the connection opening 52, so that the vibration between the two reinforcement members 10 and 20 To some extent mitigate transmission.

In order to further increase the maximum support load of the brace according to the present invention, tension members 95 are provided between the first engagement member 30 and the adjacent engagement members at the second engagement member, as shown in FIG. 18 Can be installed.

Thus, it is possible to more reliably prevent the reinforcing members 10, 20 from buckling by an external force applied.
