The present invention relates to a method for seismic reinforcement of a masonry wall, and more particularly, to an anchor for seismic reinforcement of a masonry wall using a reinforcing fiber and a method of seismic reinforcement for a masonry wall using the same.

Generally, the masonry wall has a structure in which bricks or concrete blocks are bonded by mortar. Masonry walls are used to build walls in buildings such as houses, warehouses and villas.

The masonry wall forms various walls using hexahedral bricks or concrete blocks. At this time, a mortar is placed on the bricks or blocks, and then new bricks or blocks are stacked on the bricks or blocks.

However, since the masonry wall of the building obtained from the masonry structure of the brick or block is generally formed on the outer surface of the bearing wall including concrete, when the vibration or earthquake occurs, the bonding force with the bearing wall is lost and a crack occurs. There is a problem that is broken.

In addition, by repeated and continuous micro-vibration cracks are generated in the mortar connecting the bricks and the bricks, and because the connection means between these bricks is not provided separately, the cracks may be raised in braille growth may cause large accidents have.

In order to solve this problem, the prior art, such as the Republic of Korea Patent No. 10-0628510 shown in Figure 1 is a through-hole through the masonry wall using an electric drill to form a through hole to at least a portion of the bearing wall and press-fit the reinforcement pin It was.

However, according to the prior art, the reinforcement pins are not sufficiently fixed to the bricks, and cracks are generated in the portions through which the reinforcement pins penetrate, causing a problem that the masonry wall collapses when an earthquake occurs.

In addition, according to the prior art, by forming a hole to the concrete of the bearing wall, a crack of the concrete is generated, a problem that the outer wall of the building collapses as well as the masonry wall when an earthquake occurs. In particular, in the case of old buildings, when holes are formed in the concrete wall surface of the bearing wall, the seismicity is greatly reduced.

Therefore, it is necessary to develop an earthquake-proof reinforcement method of the masonry wall so that the anchor is firmly attached to the masonry wall without causing cracking of the masonry wall and prevents the crack of the bearing wall.

The problem to be solved by the present invention is to provide a seismic reinforcement reinforcement method of the masonry wall is anchored firmly attached to the masonry wall without causing cracking of the masonry wall, prevent the cracking of the bearing wall to enable efficient seismic design.

Also, the terms 'comprise' or 'have' are intended to indicate that there is a feature, number, step, operation, component, part, or combination thereof described, or one or more other features, numbers, steps It is to be understood that the present invention does not exclude, in advance, the possibility of the presence or addition of any operation, component, part, or combination thereof.

In the present invention, "the longitudinal direction of the guide pipe" refers to the direction in which the through-hole is formed in the masonry wall. In addition, in the present invention, the "inward direction" refers to the direction from the masonry wall toward the bearing wall, and the "outward direction" refers to the direction from the bearing wall to the masonry wall. In addition, in the present invention, "thickness of the masonry wall" refers to the length of the direction in which the through-hole is formed in the masonry wall.

The inventors of the present invention have reviewed prior arts to prevent human injury caused by the collapse of the masonry wall of a building's outer wall by an earthquake, but the prior arts do not improve the seismic resistance of the building's outer wall by causing cracks in the bearing wall. I found a problem that makes it worse. Accordingly, the inventor of the present invention has developed a method for greatly improving the seismic resistance of the building outer wall by causing the adhesive to efficiently wet the gap formed in the aged building outer wall without causing cracking of the bearing wall.

The present invention provides a method for seismic reinforcement of a masonry wall constituting an outer wall of a building outside the bearing wall.

In one embodiment, (a) forming a through hole in at least one reinforcement position of the masonry wall; (b) introducing a guide tube into which the reinforcing fiber tube is inserted into the through hole; (c) injecting adhesive into the guide tube; And (d) drawing out the guide tube before the adhesive solidifies.

In this case, the through hole may penetrate the masonry wall and extend to the outside of the bearing wall, thereby not damaging the bearing wall.

In addition, the reinforcing fiber tube, the reinforcing fibers are twisted in the longitudinal direction of the guide portion includes a hollow portion formed with a tube and the silaose portion wherein the reinforcing fibers are released at one end of the hollow portion so that a plurality of silages extend freely.

For example, the adhesive may be moved in and out of the side of the hollow portion, and the hollow portion may be firmly fixed to the through hole.

For example, the silage part is introduced between the bearing wall and the masonry wall, and the adhesive flows between the bearing wall and the masonry wall along the silora part to firmly fix the bearing wall and the masonry wall. have.

For example, the silage part may be introduced into a gap formed in the bearing wall, and the adhesive may flow into the gap formed in the bearing wall along the silage part to improve the seismic resistance of the bearing wall.

For example, the reinforcing fiber tube is composed of aramid fibers, polyparaphenylene benzobisoxazole (PBO) fibers, polyarylate fibers, high toughness polyethylene (PE) fibers, carbon fibers, and combinations thereof Hybrid fibers.

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

Figure 2 shows a bobbin fiber tube and a guide tube according to an embodiment of the present invention.

The reinforcing fiber tube 10 is the reinforcing fibers are twisted in the longitudinal direction of the guide tube 20, the hollow portion 11 and the hollow fiber 11 is formed at one end of the hollow portion 11, the reinforcing fibers are loose and a plurality of thread free ends It includes a silora portion 12 extending to. The volume and length at the time of tension of the silage portion 12 are sufficiently drawn into the gap (2a in FIG. 3) between the masonry wall 1 and the bearing wall 2 and in the bearing wall 2. At the same time, it is preferable that the silage portion 12 of the portion in contact with the bearing wall 2 is so densely packed that the fixing of the reinforcing fiber tube 10 is not hindered.

For example, the length of the silage portion 12 may be 1/10 to 2/3 of the thickness of the masonry wall 1 when it is tensioned. When the length of the silage portion 12 is less than 1/10 of the thickness of the masonry wall 1, the gap formed between the masonry wall 1 and the bearing wall 2 and on the bearing wall 2 ( 2a) of FIG. 3, it may be difficult to sufficiently pull in, and when it is more than 2/3, a portion where the reinforcing fiber tube 10 and the bearing wall 2 come in contact is excessively densified by the threaded portion 12 and the reinforcing fiber tube. Fixing of the 10 in the through hole formed in the masonry wall 1 (1 a in FIG. 3) may be impeded.

As the reinforcing fiber tube 10, a reinforcing fiber having improved rigidity and heat resistance may be used than fibers for general clothing such as nylon and polyester. For example, the reinforcing fiber is a hybrid consisting of aramid fiber, polyparaphenylene benzobisoxazole (PBO) fiber, polyarylate fiber, high toughness polyethylene (PE) fiber, carbon fiber, and combinations thereof Fiber.

The aramid fibers may use para-aramid fibers and / or meta-aramid fibers, for example, using para-aramid fibers, or para-aramid fibers and meta-aramids. Combinations of fibers can be used. Aramid means a long chain synthetic aromatic polyamide in which an amide bond is directly attached to two aromatic rings in the para- or meta-position. Para-aramids include, for example, poly (para-phenylene terephthalamide) (“PPD-T”), poly (p-benzamide), and the like, and include, for example, those sold under the trade name ALKEX. Para-aramids include copolymers of para-aramid monomers such as poly (p-phenylene terephthalamide and 3,4'-oxydiphenylene terephthalamide). Meta-aramids include, for example, poly (meth-phenylene isophthalamide) (“MPIA”) sold under the trade name NOMEX.

The aramid fibers can be used, for example, hybrid fibers composed of a combination of para-aramid fibers and meta-aramid fibers, which hybrid fibers are combined or folded together in a combination operation or mixing operation of at least one fiber. It may refer to a combination of at least two base fibers made of different fiber materials that are twisted, laminated or cabled.

The base fiber refers to a filament or fiber bundle in the form as received from the base fiber manufacturer. The base fiber may or may not be twisted. The size of the base fiber and the size of the final hybrid fiber may be applied to a degree that can have a rigidity to support the wire mesh after being inserted into the through hole (1a) formed in the masonry wall (1). For example, about 250 to about 1500 d (denier) may be applied to the base fiber, and the hybrid fiber may be combined with one or two base fibers. For example, the size of the hybrid fiber may range from about 1,500 to 4,000 d.

In one example, the hybrid fiber may be formed by combining at least one base fiber of para-aramid fiber and at least one base fiber of meta-aramid fiber into a single fiber by any of a number of suitable methods. . In this case, the hybrid fiber uses a core yarn as a para aramid yarn, a covering yarn as a meta aramid spun yarn, and the form of the configuration is a para yarn of core yarn. It can take the form which spirally wraps 2 strands of meta aramid yarns which are covering yarns about 1 strand of aramid yarns. For example, the twist number of meta aramid yarns may have between 200 and 1000 TPM. If the number of twists of the yarn is less than 200TPM, the concentration of the yarn is lowered, the strength may be lowered if it exceeds 1000TPM.

For example, the surface fibers of the hybrid fiber cord may select a predetermined amount of each fiber such that the low modulus meta-aramid fibers at least partially cover, wrap, or protect the para-aramid with high modulus. have. In this case, the meta-aramid fibers can prevent the para-amide fibers from wearing themselves during repeated stress or pressure cycles or during impact and / or braiding or processing.

For example, the methods and machines used to twist and lay out the base fibers to form the hybrid fibers are not particularly limited. Suitable textile yarn machines include, for example, ring yarns, 2-for-1 yarns, direct cabler, and any other yarns known in the art. The base fibers or fibers may be blended together, laminated together, or twisted together at any convenient stage of the fiber or hose fabrication process. For example, hybrid fibers may be twisted and optionally treated with adhesive 30 prior to being placed in a braid for braiding the reinforcement layer of the hose.

In FIG. 2 again, the guide tube 20 may be, for example, a cylindrical steel pipe. The guide tube 20 guides the reinforcing fiber tube 10 into the through hole (1a of FIG. 3) formed in the masonry wall (1 of FIG. 3), and the length of the guide tube 20 is at least the masonry wall (1 of FIG. 3). Is longer than the length of the through hole (1 a in FIG. 3) formed in FIG.

Since the threaded portion 12 of the reinforcing fiber tube 10 does not maintain a constant shape, when the reinforcing fiber tube 10 is introduced into the through hole (1 a in FIG. 3) without using the guide tube 20, The portion 12 is pushed outward by the resistance of the outer wall of the through hole (1 a in FIG. 3), so that between the masonry wall (1 in FIG. 3) and the bearing wall (2 in FIG. 3) and the bearing wall (FIG. 3). The silage part 12 may be difficult to enter into the gap formed in 2) (2a of FIG. 3). Therefore, in the present invention, the silage portion 12 of the reinforcing fiber tube 10 using the guide tube 20 is between the masonry wall (1 in FIG. 3) and the bearing wall (2 in FIG. 3) and the bearing wall (FIG. 3). The gap formed in 2) of (2a of FIG. 3) can be sufficiently introduced.

3 to 10 show a seismic reinforcement method of the masonry wall according to an embodiment of the present invention.

In the seismic reinforcement method according to an embodiment of the present invention, the position of the seismic reinforcement portion of the masonry wall 1 is confirmed, and the through hole 1a is formed in the masonry wall 1 at the identified position, and the formed Remove foreign substances such as dust from the through hole (1a), the guide tube 20 is inserted into the reinforcing fiber tube 10 is inserted into the through hole (1a), and in the direction of the bearing wall (2) to the reinforcing fiber tube (10) Applying pressure, inserting the adhesive 30 into the guide tube 20, removing the guide tube 20 before the adhesive 30 solidified, and attaching the wire mesh fastening means 40 to the reinforcing fiber tube 10. It includes installing. EMBODIMENT OF THE INVENTION Hereinafter, it demonstrates concretely, drawing a drawing.

3 and 4 illustrate a method of forming a through hole in the masonry wall and cleaning the through hole according to an embodiment of the present invention.

Referring to FIG. 3, at least one or more reinforcement positions of the masonry wall 1 may be checked, and a through hole 1a may be formed at the reinforcement position. At this time, the through hole (1a) is formed so as to pass through the masonry wall (1) to the outside of the bearing wall (2). That is, according to the present invention, cracks due to damage of the bearing wall 2 can be prevented by not forming the through holes 1a in the bearing wall 2. For example, the through hole 1a may be formed to extend to the masonry wall 1 and the mortar portion 3, and may be formed as, for example, a drill 4. For example, the thickness of the masonry wall 1 and the mortar part 3 may be displayed on the drill 4 so that the drill 4 does not damage the bearing wall 2, and thus the limit drilling depth may be preset.

FIG. 4 (a) shows the cleaning method of the through hole 1a. For example, the air injector 5 can be used to shake off the through hole 1a or the sand or gravel from the mortar part 3. have. 4 (b) can be used to suck the sand or gravel in the through hole (1a) to the outside using the air inhaler (6). The process of cleaning the through hole 1a may facilitate the introduction of the guide tube 20 to be introduced thereafter, and increase the adhesive force of the silage part 12 of the reinforcing fiber tube 10. In order to achieve this same purpose, further grinding operations may be performed. Said further grinding operation is described later with reference to FIG.

Figure 5 shows a method for inserting the guide tube and the reinforcing fiber tube in the through hole according to an embodiment of the present invention, Figure 6 is a mortar portion of the reinforcing fiber tube according to an embodiment of the present invention of the mortar portion and the bearing wall It shows drawing into the gap 2a.

Referring to Figure 5, the guide tube 20 is inserted into the reinforcing fiber tube 10 is inserted into the through hole (1a). At this time, the guide tube 20 can be drawn up to the distal end of the through hole (1a). The guide tube 20 prevents the silage portion 12 from being pushed outward by the resistance of the outer wall of the through hole 1a when the reinforcing fiber tube 10 is drawn into the through hole 1a. The silage portion 12 is sufficiently introduced into the gaps 2a formed between the bearing walls 2 and in the bearing walls 2.

Referring to FIG. 6, after sufficiently introducing the guide tube 20 into the through hole 1a, the reinforcing fiber tube 10 is pressed inward, and the silage portion 12 of the reinforcing fiber tube 10 is masonry. The silage portion 12 is sufficiently introduced into the gap 2a formed between the wall 1 and the bearing wall 2 and in the bearing wall 2. Accordingly, the adhesive 30 introduced afterwards may be sufficiently wetted between the masonry wall 1 and the bearing wall 2 along the silage portion 12 and the gap 2a formed in the bearing wall 2.

Figure 7 shows a method for injecting the adhesive into the guide tube according to an embodiment of the present invention, Figure 8 shows a method for withdrawing the guide tube from the through hole after the adhesive is completed.

Referring to FIG. 7, the adhesive 30 may be introduced into the guide tube 20 using the adhesive injector 7 having the adhesive injection hose 7a, for example, into the reinforcing fiber tube 10. do. In addition, referring to FIG. 8, the guide tube 20 may be withdrawn from the through hole 1a before the adhesive 30 is solidified.

Adhesive 30 has a viscosity and elasticity, the adhesive 30 generally used for construction is made to be viscous in terms of adhesion. Therefore, when the adhesive is conventionally introduced into the through hole 1a, it is very difficult for the adhesive to flow between the masonry wall 1 and the bearing wall 2 or the gap 2a formed in the bearing wall 2. That is, when the adhesive is introduced into the through hole 1a by the conventional method, it is very difficult for the adhesive to wet the voids of the mortar portion 3 and the gaps 2a of the bearing wall 2.

However, according to the present invention, the threaded portion 12 is drawn between the load bearing wall 2 and the masonry wall 1, and the adhesive 30 adheres to the load bearing wall 2 along the threaded portion 12. It flows in between the walls 1, and can firmly fix the load-bearing wall 2 and the masonry wall 1, and can greatly improve the seismic resistance of the outer wall of a building.

In addition, according to the present invention, the silage part 12 is drawn into the gap 2a formed in the bearing wall 2, and the adhesive 30 is formed in the bearing wall 2 along the silage part 12. (2a) can flow into it. In this case, the bearing wall 2 may be made of concrete, and cracks may be generated in concrete over time, and the gap 2a may include such cracks. That is, the adhesive 30 which flowed in along the silage part 12 wets between the cracks of the bearing wall 2, and the adhesive 30 solidifies using the silage part 12 as a core, and therefore the bearing wall 2 It effectively bridges the cracks and greatly improves the seismic resistance of the building's exterior walls.

In addition, according to the present invention, the hollow portion 11 is a structure that allows the adhesive 30 to pass through the side, the side and the through hole (1a) of the hollow portion 11 after the guide tube 20 is drawn out After the adhesive 30 is filled between the outer walls of the coagulation, the hollow part 11 of the reinforcing fiber tube 10 may be firmly fixed to the masonry wall 1.

Figure 9 shows a method of installing a waterproof member in the reinforcing fiber tube according to an embodiment of the present invention.

Referring to FIG. 9 (a), before the reinforcing fiber tube 10 is completely fixed by the adhesive 30, a waterproof member 45 may be installed. The material of the waterproof member 45 is not particularly limited, and a steel material or a rubber material may be applied.

Referring to Figure 9 (b), the waterproof member 45 is applied to the form surrounding the hollow portion 11, if it has an area that can cover all the through holes (1a) formed in the masonry wall (1), its thickness And the shape is not particularly limited.

Since the adhesive 30 is viscous, a predetermined amount may flow out of the masonry wall 1 by the weight of the adhesive 30. Therefore, when the waterproof member 45 is inserted into the hollow portion 11 to cover the through hole 1a while covering the hollow portion 11, the waterproof member 45 is firmly fixed to the outer wall of the building by the adhesive 30. At the same time, the adhesive 40 does not flow out to the building exterior wall.

In addition, the waterproof member 45 is fitted to the hollow portion 11 so as to cover the through-hole 1a while surrounding the hollow portion 11, so that moisture does not flow into the through-hole 1a in a weather environment such as snow or rain. By doing so, the durability of the masonry wall 1 can be improved further.

Figure 10 shows a method of installing the wire mesh fastening means to the reinforcing fiber tube according to an embodiment of the present invention.

Referring to FIG. 10, the washer 43 and the nut 42 are inserted into the other end of the reinforcing fiber tube 10 protruding out of the masonry wall 1, and the bolt 41 is fastened to the nut 42. Bolt 41 may be fixed to the other end of the reinforcing fiber tube (10). Thereafter, the head 41 of the bolt 41, the bottom of the nut or the bottom of the washer is fixed in a net form as weave with the wire mesh 44, and external factors such as vibration or shock generated during the repair process of the masonry wall 1. This can prevent the brick of the existing masonry wall 1 from falling off.

11 illustrates a method of performing grinding on a through hole according to an embodiment of the present invention.

Referring to FIG. 11, after the through holes 1a are formed, the sidewalls of the through holes 1a and the mortar portion 3 may be ground with the wire brush 50. At this time, the grinding may be performed before the cleaning process of the above-described through hole 1a, for example, in FIGS. 3 and 4, and may be performed before the cleaning process of the through hole 1a, for example.

As an example, grinding may be performed using the wire brush 50. For example, the wire brush 50 includes a support 51 and a brush 52. The brush part 52 may include a steel wire, a reinforced fiber, a rubber material, or the like.

For example, the side wall of the through hole 1a is ground while the wire brush 50 is inserted into the through hole 1a as shown in FIG. 11 (a), and the through wire wire 50 as shown in FIG. 11 (b). While rotating in (1a), the brush portion 52 of the wire brush 50 can grind the portion of the gap 2a formed in the mortar portion 3 and the bearing wall 2, as shown in FIG. 11 (c). . Although not shown in the drawings, when the wire brush 50 is drawn out from the through hole 1a, the through hole 1a may be ground again.

In this case, the brush portion 52 may have a different length from the outside to the inside with respect to the central axis of the support 51. For example, the brush part 52 may have a shape in which the length of the outer side is longer than the length of the inner side. That is, since the brush portion 52 should have a strength that can be ground by applying a predetermined physical force to the through hole 1a and the mortar portion 3, the brush portion 52 when the density of the brush portion 52 is too high. May not reach sufficiently until the mortar portion (3).

Therefore, the outer length of the brush portion 52 is longer than the inner length is applied, and by rotating the wire brush 50 in the through hole (1a), even if the density of the brush portion 52 is not too high The brush portion 52 can efficiently grind to the gap 2a formed in the through hole 1a, the mortar portion 3, and the bearing wall 2.

That is, the seismic reinforcement method of the masonry wall according to the present invention further includes a method of grinding the through hole 1a using the wire brush 50 described above, whereby the reinforcing fiber tube 10 is more firmly formed in the through hole 1a. It is possible to greatly improve the durability of the outer wall of the building by being fixed.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings. However, since the above-described embodiments have only been described by way of example, the present invention is limited to the above embodiments. It should not be understood, the scope of the present invention will be understood by the claims and equivalent concepts described below.
