Description

Technical Field [0001] The present invention relates to a seismic retrofitting structure of infilled masonry wall and construction method,

The present invention eliminates the need to dismantle existing coarse-walled walls, and can improve the in-plane damping effect while preventing the collapse of the coarse-walled wall during an earthquake, and can prevent an increase in stiffness of the non- And a method of constructing the same.

Recently, seismic retrofitting and related technologies have been actively developed for buildings that do not have existing seismic design such as schools due to recent earthquake occurrence frequency and size increase.

For example, as shown in FIG. 1, there is a technique for a double-frame seismic reinforcing structure in which a reinforcing frame is fixed and reinforced in an opening of a frame formed of a column and a beam at the front of the building (Japanese Patent No. 10-1357054).

Since the above technique is reinforced only in the lateral direction of the building, that is, in the X-directional load, separate reinforcement is required for the longitudinal direction, i.e., the Y-directional load.

Accordingly, since the framed structure in the longitudinal direction is generally constituted by the roughly filled structural wall W1 which is weak against the earthquake, the projected wall W1 is removed and an anchor is installed on the frame. Then, the reinforced concrete structure (Refer to Fig. 3).

However, this construction is not possible to use the building during the construction due to the removal of the existing wall, and it takes a lot of work time because anchor, reinforcement, formwork installation and dismantling and concrete pouring work are involved. In addition, since the concrete must be placed in the frame in the state where the outer frame is held, it is difficult to cast the concrete.

In addition, if the masonry wall, which was previously designed as a non-bearing wall, is simply changed to a reinforced concrete structure, which is a rigid wall, it will increase the rigidity of the wall and increase the burden on the foundation. Accordingly, there is a problem that the foundation or the ground must be further reinforced or a separate damper must be installed.

In addition, FIG. 2 shows an example of a seismic strengthening structure of a masonry reinforced concrete structure capable of improving seismic performance by fixing a reinforcing plate, which is a metal plate, to both sides of a masonry filled wall without detaching the existing masonry filled wall, (Patent No. 10-1657481).

However, the above technique has a problem that the load of the foundation is increased because the rigid wall is rigidly reinforced and the rigidity of the wall is increased. In addition, in general, the roughness-filled wall is inferior in the accuracy of installation due to the non-bearing wall, so that the outer surface of the roughly-walled wall is uneven and it is difficult to closely fix the reinforcement plate.

In order to solve the above-mentioned problems, the present invention is constructed to enable the earthquake-proof reinforcement without demolishing the masonry-filled wall, thereby making it possible to use the building during the construction and to perform the complicated process according to the demolition and construction of the wall, Reinforced structure and a construction method thereof.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

FIG. 4 is a perspective view of a structure-reinforced quartz wall-reinforced structure of the present invention, and FIG. 5 is a side cross-sectional view of the structure-reinforced quartz wall-reinforced structure of the present invention.

As shown in Figs. 4 and 5, the structure-reinforced quartz wall-reinforced structure of the present invention comprises a rough fill wall 2 filled in a frame 1 composed of a column 11 and a beam 12; And a reinforcing plate (3) provided at both sides of the rough filler wall (2) in a longitudinal direction and spaced apart from the outer surface of the rough filler wall (2) by a predetermined distance. .

The rough filler wall 2 is filled in the frame 1 made up of the column 11 and the beam 12.

In the case of the first layer, the lower beam 12 refers to the slab 12 '.

Since the rough filler wall 2 is not demolished, there is no complicated process due to demolition and rework of the wall, and no problems such as an increase in air. In addition, buildings can be used during construction.

The reinforcing plate 3 is provided on both sides of the rough filler wall 2 in the longitudinal direction and is spaced apart from the outer surface of the rough filler wall 2 by a predetermined distance.

The reinforcing plate 3 is provided on the outer surface of the rough filler wall 2 and acts as a damper for dissipating energy itself against seismic loads.

Since the reinforcing plate 3 is spaced apart from the rough fill wall 2 by a predetermined distance, the rough fill wall 2 is not crossed. Therefore, the reinforcing plate 3 prevents the collapse of the masonry filled wall body 2 while allowing the cracks of the masonry filled wall body 2 in the seismic load action.

That is, the rough filler wall 2 with cracks also dissipates energy and does not increase the rigidity of the non-bearing wall structural filler wall 2 by allowing the cracks of the rough filler wall 2 to have no effect on other members .

The reinforcing plate 3 may be made of a steel plate or the like.

The reinforcing plates 3 can be joined in a plurality of rows according to the width of the rough filler wall 2.

The reinforcing plate 3 can be used not only in a building longitudinal wall but also in a lateral non-proof structural wall.

For example, the present invention can be applied to a wall between a hall and a classroom in a school building. When the present invention is applied to a wall between a classroom door and a window, it can be used without changing the size of a window or a door.

As described above, the present invention does not dismantle the existing masonry wall and can prevent the masonry wall 2 from collapsing during an earthquake, and improve the in-plane direction damping effect. In addition, since the rigidity of the unfitted wall member 2 is not increased, the additional load is not transferred to the other members, so that it is not necessary to further reinforce the foundation.

As shown in FIG. 5 and the like, a lower fixing plate 34 may be provided at the lower end of the reinforcing plate 3 to be vertically bent outward and fixed to the floor.

Accordingly, the lower fixing plate 34 is formed by bending the lower end of the reinforcing plate 3 so as to have an L-shape as a whole, and the lower fixing plate 34 can be firmly fixed to the floor with the anchor bolts.

At this time, the existing building may have some difference in floor height depending on floor level. Therefore, the length of the lower fixing plate 34 may be somewhat shortened, but the non-shrinking mortar G may be grouted at the lower portion of the lower fixing plate 34 to adjust the level to match.

Fig. 6 is a side sectional view showing the details of the upper fixing part, and Fig. 7 is a side sectional view showing the details of the lower fixing part.

6 and 7, a support plate 41 fixed to the outer surface of the upper part of the rough filler wall 2 and an upper beam 41 bent outward from the upper end of the support plate 41, An upper fixing part 4a composed of a fixing plate 42 coupled to the lower part of the rough filler wall 12 and a lower fixing part 4b fixed to the lower outer side face of the rough filler wall body 2, And the reinforcing plate 3 can be configured such that upper and lower portions are fixedly coupled to outer surfaces of the support plate 41 and the lower fixing portion 4b of the upper fixing portion 4a.

In other words, the upper fixing portions 4a can be coupled to both sides of the upper portion of the rough filler wall 2, respectively.

The upper fixing part 4a is composed of a supporting plate 41 and a fixing plate 42 and is formed as a whole.

The support plate 41 is fixed to the outer surface of the upper portion of the artificial filling wall body 2.

The upper portion of the reinforcing plate (3) is fixedly coupled to the outer surface of the support plate (41).

The fixing plate 42 is bent outward from the upper end of the supporting plate 41 and joined to the lower portion of the beam 12 of the frame 1. [

The fixing plate 42 can be fixed to the bottom surface of the beam 12 with an anchor bolt.

However, depending on the working direction, it may be difficult to directly apply the fixing plate 42 to the lower surface of the beam 12 with the anchor bolts. 6, the side fixing plate 43 may be coupled to the upper surface of the fixing plate 42 to cover the outer surface of the beam 12, and the side fixing plate 43 may be fixed to the side surface of the beam 12 with the anchor bolts.

And the lower fixing portion 4b can be coupled to both sides of the lower portion of the rough filler wall 2, respectively.

The lower portion of the reinforcing plate 3 is fixedly coupled to the outer surface of the lower fixing portion 4b.

That is, the upper fixing part 4a and the lower fixing part 4b fix the reinforcing plate 3 to the frame 1. More specifically, the upper and lower portions of the reinforcing plate 3 are fixed to the frame 1 by the upper fixing portion 4a and the lower fixing portion 4b, respectively.

Accordingly, when the frame 1 is deformed due to the occurrence of an earthquake, the reinforcing plate 3 deforms and dissipates energy.

When the reinforcing plate 3 is coupled to the outer surface of the supporting plate 41 of the upper fixing part 4a and the outer surface of the lower fixing part 4b, the reinforcing plate 3 is supported by the supporting plate 41 or the lower fixing part 4b The wall of the roughly filled wall body 2 can be separated from the outer wall of the roughly walled wall body 2.

When the reinforcing plate (3) is damaged, only the reinforcing plate (3) can be removed and replaced, so that it is easy to repair and reinforce.

When the lower fixing plate 34 is bent on the lower fixing portion 4b so that the lower fixing portion 4b is L-shaped and fixed to the upper surface of the slab 12 '(not shown), the reinforcing plate 3 It can be constructed in a simple planar shape.

The reinforcing plate 3 can be fixedly connected to the supporting plate 41 and the lower fixing portion 4b of the both side upper fixing portions 4a of the masonry filled wall body 2 by through bolts 7 respectively penetrating therethrough.

It is possible to simultaneously connect the upper portion of the roughly filled wall body 2 with the both side support plates 41 and the reinforcing plate 3 by using the through bolts 7. The lower portion of the roughly filled wall body 2 and the lower both side fixing portions 4b And the reinforcing plate 3 can be joined at the same time.

The fastening holes may be previously formed at positions corresponding to the support plate 41, the upper portion of the reinforcing plate 3 and the rough filler wall 2 so that the through bolts 7 can pass through. Similarly, a fastening hole through which the through bolts 7 can pass can be formed at positions corresponding to the lower fixing parts 4b and the lower part of the reinforcing plate 3 in advance.

The through bolts (7) maintain the gap between the side reinforcing plates (3). Thus, the reinforcing plate 3 supports the masonry filled wall body 2 so as not to collapse even after cracks have occurred in the masonry filled wall body 2.

FIG. 8 is a perspective view showing a coupling relation between the reinforcing plate and the first fixing plate, and FIG. 9 is a front view showing an embodiment of the insertion hole and the fastening hole formed in the reinforcing plate.

5, 8 and so on, at least one first fixing plate 5 may be provided between one side of the rough filler wall 2 and the reinforcing plate 3.

The first fixing plate 5 maintains a gap between the rough filler wall 2 and the reinforcing plate 3. In addition, since the outer surface of the roughly filled wall body 2 is supported, the roughly filled wall body 2 is prevented from collapsing after cracks are generated.

The plurality of first fixing plates 5 may be spaced apart from each other depending on the height of the rough filler wall 2. [

In addition, the first fixing plate 5 may be made of various materials such as a steel plate, a synthetic resin, a wood, and a rubber.

The reinforcing plate 3 can be fixedly coupled by through bolts 7 penetrating the first fixing plate 5 on both sides of the masonry filled wall body 2. [

The first fixing plate 5 supports the masonry filled wall body 2 together with the reinforcing plate 3 when cracks generated in the masonry filled wall body 2 intensify and the masonry filled wall body 2 tries to collapse to the out- Should be able to. Therefore, the first fixing plate 5 and the reinforcing plate 3 on both sides of the roughly filled wall body 2 should be connected to each other to maintain a gap therebetween.

That is, even after the cracks of the roughly filled wall body 2, the gap between the first fixed plate 5 and the reinforcing plate 3 on both sides of the roughly filled wall body 2 must be kept constant to properly support the roughly filled wall body 2 have.

Therefore, both the first fixing plate 5 and the reinforcing plate 3 on both sides can be fixed by using one through bolt 7.

For this purpose, a fastening hole through which the through bolts 7 can penetrate can be formed in advance at positions mutually corresponding to the first fixing plate 5, the reinforcing plate 3 and the rough filling wall body 2.

As the number of the through bolts 7 increases, the roughly filled wall body 2 is laterally restrained to increase rigidity. Therefore, it is preferable to minimize the gap between the side reinforcing plates 3 so as to maintain the gap therebetween.

8 and 9, the reinforcing plate 3 is formed with a fastening hole 32 to which the through bolt 7 is coupled, and a first fastening plate 32 is fastened to one side of the fastening hole 32, The insertion hole 33 into which the head or the nut of the through bolt 7 for fixing the bolt 7 to the roughly filled wall body 2 is inserted may be formed to communicate with the fastening hole 32. [

As described above, the upper fixing part 4a and the lower fixing part 4b are first installed and fixed to the masonry wall 2 and then the upper and lower parts of the reinforcing plate 3 are fixed to the upper fixing part 4a The reinforcing plate 3, the supporting plate 41 and the reinforcing plate 3 or the reinforcing plate 3 are fixed by the through bolts 7 in the state of being in close contact with the outer surface of the outer surface of the supporting plate 41 and the outer surface of the lower fixing portion 4b. , The lower fixing portion 4b and the rough filler wall 2 can be fastened.

However, since the first fixing plate 5 is in the form of a flat plate, it is difficult to fix it separately from the reinforcing plate 3.

After the reinforcing plate 3 is first installed and the first fixing plate 5 is sandwiched between the reinforcing plate 3 and the masonry filling wall 2 and the operator holds the first fixing plate 5 It is possible to consider a method of fastening and connecting the through bolts 7. However, it is difficult for the operator to hold the first fixing plate 5, which is relatively wide and heavy in weight, through the space between the reinforcing plate 3 and the masonry wall 2, to be.

Therefore, the first fixing plate 5 on both sides is temporarily fixed with the penetrating bolts 7 as shown in FIG. At this time, the first fastening plate 5 can be fastened by fastening the nut to the through bolt 7. The reinforcing plate 3 is attached to the outside of the first fixing plate 5 so that the head or nut of the through bolt 7 already fastened to the insertion hole 33 of the reinforcing plate 3 is inserted The rear reinforcing plate 3 is pushed to the side so that the trunk portion of the through bolt 7 is moved toward the fastening hole 32 side.

The first fixing plate 5 and the reinforcing plate 3 can be easily attached to the roughly filled wall body 2 without the additional attraction by fixing the reinforcing plate 3 on the basis of the through bolts 7 and the nuts in the outer side of the fastening holes 32. [ ) Can be combined.

FIG. 10 is a perspective view showing a coupling relationship between the reinforcing plate and the first fixing plate by the insert nut, and FIG. 11 is a side sectional view showing the rough filling wall to which the insert nut is coupled.

10 and 11, the reinforcing plate 3 and the first fixing plate 5 are formed with fastening holes 32 and 51 through which the through bolts 7 pass, respectively, The reinforcing plate 3 and the first fixing plate 5 are fixed to the inner circumferential surface of the fastening hole 51 of the plate 5 by an insert nut 8 fastened to the fastening holes 32 and 51 They can be combined with each other. At this time, the insert nut 8 has a cylindrical shape with both ends thereof opened so that the through bolts 7 can penetrate, and a thread is formed on the outer circumferential surface of the insert nut 8 so as to be screwed into the fastening holes 51 of the first fixing plate 5 And a flange portion 82 protruded outward at one end of the body portion 81 so as to be engaged with the outer side of the reinforcing plate 3.

The reinforcing plate 3 and the first fixing plate 5 can be provided on the rough filler wall 2 in a state where they are integrally joined together by a method such as an adhesive or welding.

However, in this case, if the reinforcing plate 3 is damaged due to an earthquake or the like, it is not economical since the unfixed first fixing plate 5 must be replaced at the same time.

Therefore, the reinforcing plate 3 and the first fixing plate 5 may be integrally formed with the insert nut 8 in advance, and then integrally formed on the wall 6.

That is, the insert nut 8 can be used so that the reinforcing plate 3 and the first fixing plate 5 can be detachably coupled to each other by means of the through bolts 7 so that they can be fastened to the rough wall body 2. have.

The through bolt (7) penetrates through the body portion (81) of the insert nut (8) and is fastenable.

It is preferable that the flange portion 82 of the insert nut 8 is formed in a polygonal shape so as to be screwed to the first fixing plate 5 by rotating it with a tool.

12 is a front view showing various embodiments of a reinforcing plate in which a cut-out hole is formed;

As shown in FIG. 12, the reinforcing plate 3 may have a plurality of cut-out holes 31 formed therein.

By forming a plurality of cut-out holes (31) through the reinforcing plate (3), the weight of the reinforcing plate (3) can be reduced and the weight can be reduced.

In addition, since the cross-sectional loss is artificially formed in the reinforcing plate 3, the deformation of the reinforcing plate 3 is naturally induced, and the energy dissipation due to the deformation of the reinforcing plate 3 is possible.

12 (a) to 12 (e), the size and spacing of the incising hole 31 can be variously configured. In addition, the shape of the cut-out hole 31 may be variously adopted, such as a polygon such as a rectangle, a circle or a hexagon.

FIG. 13 is a front view showing a state in which the reinforcing plate having the second fixing plate is engaged, and FIG. 14 is a cross-sectional view showing a state in which the reinforcing plate having the second fixing plate is engaged.

13 and 14, the cut-out hole 31 is formed in a plurality of rows in the transverse direction, and one side of the cut-out hole 31 is in close contact with the roughly filled wall body 2, And a second fixing plate 6 fixed to the reinforcing plate 3 may be coupled to the other side surface.

Since the rough filler wall bodies 2 are formed by laminating a plurality of separated bricks each in the upper, lower, left, and right sides, the entire rough filler wall 2 does not behave as a whole when cracks occur.

Therefore, it is necessary to connect and fix the reinforcing plate 3 at various points of the masonry filled wall body 2 in order to dissipate energy against deformation occurring in the roughly filled wall body 2 itself.

Therefore, by using the second fastening plate 6 having a narrow band shape to connect the roughly filled wall body 2 at a plurality of points, deformation of each part of the roughly filled wall body 2 can be prevented from being deformed to the reinforcing plate 3 To dissipate the energy.

The second fixing plate 6 is provided to transmit the deformation or stress of the masonry filled wall body 2 to the first fixing plate 6 for maintaining the interval between the masonry filled wall body 2 and the reinforcing plate 3 described above, (5).

In the embodiment of FIG. 13, the second fixing plates 6 are positioned between the upper and lower cut-out holes 31 and are arranged in a plurality of rows so as to be spaced apart from each other.

The second fixing plate 6 may be applied when the reinforcing plate 3 is installed or may be added when it is determined that additional reinforcement is required during use of the present invention.

The second fixing plate 6 is fixed to the roughly filled wall body 2 by an anchor bolt 9 which is anchored to the roughly filled wall body 2 through the reinforcing plate 3 and the second fixing plate 6 .

Since the second fixing plate 6 is for transmitting deformation of the masonry filled wall body 2, the second fixing plates 6 on both sides of the masonry filled wall body 2 are coupled with each other using the through bolts 7 no need. It is sufficient that the second fixing plate 6 is fixed to one side of the roughly filled wall body 2 by the anchor bolts 9, respectively.

On the contrary, when the reinforcing plates 3 on both sides are connected through the rough filler wall 2 for fixing the second fixing plate 6, the rough filler wall 2 is restrained and the rigidity of the wall is increased. desirable.

For this purpose, the reinforcing plate (3) and the second fixing plate (6) may be provided with through holes for passing through the anchor bolts (9) at mutually corresponding positions.
