The present invention is press-fitted into the inner wall and fastening the fix holder to the fix, and then connect a separate fix to the rear of the fix holder to connect the indented fix in the left and right direction and connect the fix near the center of the fix holder It is related with the masonry reinforcement method that can connect the fix in the up and down direction and can reinforce it with only the fix, fix holder and bracket without the need for additional parts.

A masonry wall is an architectural structure that builds a wall by stacking stones, bricks, concrete blocks, etc., and is a smooth structure of brick, stone, and concrete block structures without reinforcement. Also called. In general, the durability (耐久性) is excellent, especially the stone is a structure that has been used for a long time. In Western Europe, where there are few earthquakes, structural methods are used, and arches and domes, which are excellent in design, have been completed for a long time, and brick structures are still widely used.

The brick structure is not only stacking bricks but also stacking bricks on the outer surface of the inner wall made of concrete, etc., and the bonding force between the inner wall and the brick is very important. When the binding force between the inner wall and the brick wall falls, the brick that has been stacked may be collapsed by an earthquake, impact or wind pressure.

Therefore, it is necessary to closely bond the masonry with the inner wall to prevent various safety accidents caused by the collapse of the brick.

Therefore, the present invention is to solve the conventional problems as described above, and after pressing the fix on the inner wall and fastening the fix holder to the fix by connecting a separate fix to the rear of the fix holder in the left and right direction It is an object of the present invention to provide a masonry reinforcement method that can reinforce the masonry wall by connecting the press-fitted fixtures in the vertical direction by connecting the fix near the center of the fix holder.

In order to achieve the above object, the present invention is a method for reinforcing the masonry wall, a fix-indentation process for pressing a fixed distance fixed to the inner wall of the masonry wall along the circumference of the building, a fix holder at the rear end of the fixes pressed into the inner wall It is based on a method of performing a fix holder fastening process for fastening, a fix left and right connecting process for connecting the rear ends of the fix holders to a release-plated steel wire having a separate fix or irregularities.

Here, when the masonry reinforcing method is constructed on the already constructed masonry wall, before the process of fixing the press, crush the joint around the brick of the portion to be pressed into the fixed interval along the circumference of the building to extract the brick, extract After extracting and removing the joints by removing the joints in the lower part of the bricks arranged on both sides of the wealth by 1/3 depth, after the fixation left and right connection process, the extracted bricks are again placed in the extraction unit. In addition, a brick insertion and mortar injection process for injecting mortar is performed along the joint portion which has been removed in the circumferential direction of the building and around the brick.

Here, after the brick insertion and mortar injection process is carried out, the phosphorus reinforcement fix is driven into the upper part of the window.

In addition, when the masonry reinforcing method is constructed on a new construction masonry, the lower brick masonry process of masonry until the height of the building to which the fix is pressed, just before the fix-indentation process, and after the fix left and right connection process, The upper brick masonry process is carried out to mason the bricks above the height of the pressed building.

In this case, the fix up and down connection process is performed to connect another fix to the center portion of the fix holder in the height direction of the building together with the right and left connection process. Mortar is injected into the hole while masonry so as to penetrate the hole formed in the hole.

The fixation includes a plurality of wings protruding outwardly from a predetermined spacing position around the mandrel and the mandrel, the center of which has a screw wound along the longitudinal direction of the fix about the mandrel, the fixer holder Has a cylindrical cylindrical portion and a plurality of wing accommodation portions projecting outward at predetermined intervals such as the wings around the cylindrical portion to accommodate the plurality of wings, wherein the wing accommodation portion is like a screw along the longitudinal direction of the cylindrical portion; When the pitch of the wing and the pitch of the wing receiving unit coincide with each other, the fixation is performed while the fix and the fix holder are relatively rotated when the fix and the fix holder are fastened in the longitudinal direction.

Here, it is preferable that the wing and the wing accommodation portion consists of two or three.

Here, when the fixation and the fix holder is fastened, there is a gap between the wing and the wing receiving portion, a space exists between the mandrel and the tubular portion, and when inserting a mortar to bury the fix holder and forming a joint. The rear end of the fix holder is exposed to the outside of the joint so that the inside and the outside of the masonry wall are ventilated.

Here, the end of the fix holder is formed with a through hole drilled in the vertical direction in the longitudinal direction of the fix holder, by inserting a release-plated iron wire having a separate fix or irregularities formed in the through hole of the fix holder in the fixation right and left connection process Connect the release plated wire with a separate fix or irregularities.

In addition, the bracket is used in the fixing up and down connection process, the bracket has an elastic fastening portion that is elastically fastened to the central portion of the fix holder, a through hole formed on the side of the fastening portion, the connection of the fix holder and another separate fix In this case, the elastic fastening part is inserted into the center of the fix holder to fasten the bracket and the fix holder, and the fixation to be connected in the vertical direction is inserted into the through hole of the bracket.

Hereinafter, an embodiment of a reinforcing method of a masonry wall according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a shape view (FIG. 1A) and a cross-sectional view (FIG. 1B, FIG. 1C) of a fix 1 used in a masonry wall reinforcement work according to an embodiment of the present invention, and FIG. 2 is the fix 1 of FIG. 1. Fig. 2A and Fig. 2B and Fig. 2C are diagrams of the fix holder 2 used together.

Fix (1) is a metal material of high strength that is not corrosive to moisture, etc., and consists of a center axis 11 and a plurality of wings 12 protrude outward at a predetermined interval around the axis, the wing 12 is It is made of a shape wound like a screw along the longitudinal direction of the fix (1) around the mandrel (11). There is no limit to the number of wings 12, but it is advantageous in that two wings (see FIG. 1C) or three (see FIG. 1B), as shown in the figure, satisfy both strength and simplification of structure at the same time. There is a face.

The fix holder 2 is made of a metal material that does not corrode moisture, for example, stainless steel, aluminum, brass, or plastic material, and protrudes outward at a predetermined interval around the cylindrical tubular portion 21. A plurality of, preferably two (see FIG. 2C) to three (see FIG. 2B) wing receptacles 22 corresponding to the number of the wings 12 are like screws along the longitudinal direction of the fix holder 2. It is made of a wound shape. At both ends of the fix holder 2, there are formed through holes 23 that are opened laterally. The through hole 23 is in the shape of a circular hole having a diameter enough to fit the wings 12 of the fix 1.

Here, the pitch P by the blade | wing 12 of the fix 1, and the pitch P by the blade accommodation part 22 of the fix holder 2 correspond.

3 is an exemplary view showing a fastening example of the fix 1 of FIG. 1 and the fix holder 2 of FIG. 2, and FIG. 3A shows a state in which the fix 1 is connected in the longitudinal direction through the fix holder 2. 3B shows a state in which the fixes 1 are connected to each other in a direction perpendicular to each other through the fix holder 2, and FIGS. 3C and 3D are cross-sectional views in a state in which the fix 1 and the fix holder 2 are fastened. 3A is a cross-sectional view illustrating the ZZ cross section in FIG. 3A. 4 is a physical diagram in a separated state and a fastened state of the fix 1 of FIG. 1 and the fix holder 2 of FIG. 2.

As shown in FIG. 3A, the fix 1 may be inserted into and fastened to the fix holder 2. Referring to FIGS. 3C to 3D, the wings 12 of the fix 1 are shaped to be fitted into the wing receiving portion 22 of the fix holder 2 while maintaining a slight gap G. Accordingly, when the fixer 1 and the fixer 2 are relatively rotated as if the screws are fastened, the fixer 1 may be inserted into the fixer 2. Geometrically, the length from the center of the fix 1 to the end of the wing 12 is longer than the length from the center of the fix holder 2 to the outer surface of the tubular portion 21, so that the wing 12 has a wing receiving portion. Interfering with the boundary between the 22 and the tubular portion 21, the fix 1 is to be fixed in the fix holder (2). Once the fix holder 2 is installed on the masonry wall, since the outside of the fix holder 2 is covered with mortar, the fix holder 2 is not deformed even if the fix 1 moves and presses the fix holder 2, so that the fix holder 2 is not deformed. (1) is more firmly supported by the fix holder (2).

In addition, the through-hole 23 formed at the end of the fix holder 2 after the fix holder 2 is rotated and fastened in a state in which the fix 1 is pressed into the inner wall C such as a concrete wall and fixed. Through this, another fix 1 can be penetrated in a direction perpendicular to the lateral direction of the fix holder 2, that is, the longitudinal direction of the fix 1 pressed into the wall. Alternatively, instead of another fix 1, it is also possible to use a release-plated iron wire having irregularities formed so that the adhesion to mortar is improved.

Since the fix (1) and the fix holder (2) has a shape in which the wing 12 and the wing receiving portion 22 are wound like a screw in the longitudinal direction, respectively, only the rotation relative to both members is fastened as the screw is engaged. This can be done very simply. In addition, since the pitch of the fixer 1 and the fixer 2 of the present application is relatively long compared to the pitch of the screw of a general mechanical element, even if the fixer 1 and the fixer 2 are fastened to each other by only about one pitch, the longitudinal direction It can be tightened very firmly. When viewed in cross-sectional shape, the blades 12 and the wing receiving portion 22 in the fix 1 and the fix holder 2 increase the cross-sectional coefficient of the member to increase the bending rigidity of the member.

In addition, if only the above-described fix (1) and the fix holder (2), as shown in Figure 3a, by fixing two fixes (1) on both sides of the fix holder 2, the length of the fix (1) can be easily extended, Figure 3b As such, the fix 1 can be inserted into the through hole 23 of the fix holder 2, so that the fix 1 and the fix 1 may be perpendicular to each other.

Also, as shown in FIGS. 3C to 3D, when the fix 1 and the fix holder 2 are fastened, there is a gap G between the wing 12 and the wing receiving portion 22. When the fix 1 and the fix holder 2 are used, the vibration generated in the building can be absorbed to some extent by the gap G, and it is possible to cope with thermal expansion of the material due to the change of the season or the like. In addition, the space S between the mandrel 11 of the fixer 1 and the tubular portion 21 of the fixer 2 enables the ventilation of moisture or air to prevent corrosion due to water trapping. It can also ventilate the hot heat of the space walls to the outside in summer.

Hereinafter, a repair method for reinforcing a masonry wall using the fix 1 and the fix holder 2 described above will be described.

FIG. 5 is a view showing the masonry wall W to be repaired using the fix 1 and the fix holder 2 of FIGS. 1 and 2, FIG. 6 is a detailed perspective view of the portion A of FIG. It is a figure which shows the procedure of the method of reinforcing and repairing a masonry wall using the fix 1 and fix holder 2 of FIG.

In order to reinforce and repair the masonry wall, the brick B of the wall W to be repaired is extracted at regular intervals in the circumferential direction of the building, and the joint M of the remaining unextracted brick in the depth direction is about 1/3 of the depth direction. After removal, the fixation 1 is rotationally press-fitted into the inner wall C (material such as concrete) of the extraction section E, and after the fixer 2 is fastened from the rear end thereof, the rear end of the fix holder 2 Inserting a separate fix (1) in the circumferential direction of the building through the through holes (23) formed in the, so that the fix (1) fixed to each of the plurality of extraction section (E) is a separate fix in the circumferential direction of the building again It can be fixed by (1). It is also possible to use a release-plated iron wire having irregularities instead of the separate fix 1 as described above.

In detail, first, as shown in FIG. 7A, the joint M around the brick B of the portion E to which the fix 1 is to be pressed is crushed and removed, and the corresponding brick is extracted, and then the extraction unit is extracted. The joints (M) at the bottom of the bricks (B) arranged on both sides of (E) are crushed and removed by about one third the depth of the bricks as shown in part D (brick extraction and joint removal process). Although only one brick is illustrated in the drawing, one to three bricks may be extracted to secure a work space.

Thus, the bricks are extracted at regular intervals in the circumferential direction of the building, and the joints are dug deeply in the circumferential direction of the building. .

Next, as shown in FIG. 7B, the fix holder 2 is rotated into the rear of the press-fitted fixer 1 and fastened so that the through-holes 23 at the rear end of the fix holder 2 face both sides. . In this case, the length of the fix holder 2 is made to be about the depth of the brick 2 so that the front end of the fix holder 2 is positioned to the inner surface of the brick B and the rear end is exposed to the outer surface of the brick B. (Fixholder fastening process). As will be described later, this allows the both ends of the fix holder 2 to be exposed out of the joint so that the space between the fix 1 and the fix holder 2 (S; see FIG. 3C) serves as a vent, and at the same time, the construction can be performed without missing materials. Provide an indicator that allows the supervisor to verify that the commitment has been made in good faith.

Next, as illustrated in FIG. 7C, the fixer 1 is inserted through the through hole 23 at the rear end of the fix holder 2 and disposed along the joint part which has been removed in the circumferential direction of the building. The fix 1 is continuously inserted through the through hole of the rear end of another fix holder fixed to the neighboring brick extraction unit. If the fix 1 is short, another fix holder is used as described above with reference to FIG. 3A. Fixes can be linked together (fixed left and right linking process).

After going through the process shown in FIGS. 7A to 7C along the circumferential direction of the building, the brick B extracted as shown in FIG. 7D is again placed in the extraction unit E, and then the surroundings of the brick B and the building The joint is formed by injecting mortar along the joint portion removed in the circumferential direction of (brick insertion and mortar injection process). At this time, both ends of the fix holder (2) to protrude to the outside of the joint by mortar to ensure good ventilation and easy supervision of the supervisor. Note that when the joint M is large in thickness, the bonding force between the bricks B may be weakened. Therefore, it is preferable to limit the outer diameter of the fix holder 2 to within about 10 mm to prevent the joint thickness from increasing.

And if the repair is done in the upper part of the window directly into the upper part of the window (10) to the upper part of the window.

Through the above-described process, the fixer embedded in the inner wall is firmly connected to the circumferential direction of the building by the fix holder and the fix again, and the mortar is reinjected and fixed to this part, so that the masonry wall is reinforced and repaired very strongly.

The above method describes the repairing method that can be used in the case of the already applied masonry wall, but the reinforcement of the masonry wall is not necessarily used only for the repair of the already completed building, and it can be applied to the construction of new wall. Is self explanatory.

In the case of the stretched wall, the process of crushing the joint M and extracting the brick B, and the joint M at the lower part of the bricks B arranged on both sides of the extraction unit E are performed. It does not need to go through the process of crushing and removing by 3 depths (brick extraction and joint removal process), and extracts the brick (B) extracted after the installation of the fix (1) and the fix holder (2). ), It is not necessary to carry out the process of injecting mortar (brick inserting and mortar injecting process) along the joint portion which has been removed around the brick (B) and in the circumferential direction of the building.

That is, in the case of the stretched wall, as shown in FIG. 7A, in the state in which the brick B is stacked only up to the M1 stage (lower brick masonry process), that is, before the stages of the M2 or more stages are still stacked, the above-described fix-indentation process, After the fix holder fastening process and the fix right and left connection process, the process of masonry the M2 or more stages (the upper brick masonry process) may be performed.

In addition, in the case of the expansion wall, in addition to the above-described method, it is possible to further reinforce the building in the height direction.

FIG. 8 is a perspective view illustrating a method of reinforcing and expanding a masonry wall using the fix 1, the fix holder 2, and the bracket 3 of FIGS. 1 and 2, and FIG. 9 is a front view of the masonry wall of FIG. 8. 9A and a side view (FIG. 9B is a QQ cross section of FIG. 9A, and FIG. 9C is a RR cross section of FIG. 9A). FIG. 8 is a masonry wall under reinforcement and expansion, and the brick and the joint of the portion F are omitted for convenience of description.

When reinforcing the masonry wall while reinforcing in the up and down direction, a brick (B) having a hole (BH) formed thereon and a bracket (3) that can be fastened to the fix holder (2) while fixing a fixation extending in the up and down direction are used. do. The bracket 3 includes an elastic fastening portion 32 which can be fastened to the fix holder 2 by elasticity, and a through hole 31 formed on the side of the elastic fastening portion 32.

Stretching masonry is a process of stacking bricks (B) from the bottom one by one, thus eliminating the hassle of removing bricks and joints and installing bricks and joints again, as in the already completed walls. The fix 1 may be further installed in the height direction of the building through the formed hole BH.

In detail, after masonry (B) to the X1 stage brick (B) is not yet masonry in the X2 stage by inserting the fix (1) into the inner wall (C) (fix press-in process), this fix The fix holder 2 is fastened to the rear of the (1). At this time, the through hole 23 of the fix holder 2 is rotated and adjusted so as to penetrate in the circumferential direction (left and right directions) of the building (fix holder fastening process).

In this state, a separate fix 1 is inserted into the through hole 23 of the fix holder 2 along the circumferential direction of the building (fixed left and right connection process), and an elastic body is formed in the middle of the fix holder 2. Insert the bracket (32) by inserting the bracket (3) and through the through hole 31 formed in the bracket (3) by inserting another additional fix (1) in the direction of the height of the building (fixed up and down connection process) . Here, the bracket 3 is sufficient if it has a part connected to the fix holder 2 and a part through which another separate fix is penetrated, and is not necessarily limited to the shape shown in the drawing, and it is necessarily press-fitted. This does not have to be.

In the upper brick masonry process, mortar is formed between the X1 and X2 stages and the brick (B) between the X1 and X2 stages by stacking the bricks (B) at the X2 stage while fitting the holes (BH) into the fixed (1) connected in the vertical direction. In addition, mortar is also injected into the hole BH of the brick B through which the fixer 1 installed in the up-down direction passes. Bricks (B) from X3 to X8 are similarly stacked and mortar is injected into the joint and the hole of the brick.

Before stacking the bricks (B) in the X9 stage, the fix indentation process, the fix holder connection process, the right and left fixation and the up and down connection process may be performed, and then the mortar injection and the upper brick masonry process may be continued again.

The vertical connection process of the fix 1 connects the fixes 1 press-fitted to the inner wall C up and down as in the left and right connection process of the fix 1.

When laying bricks, as shown in Fig. 9b, the up-and-down fix 1 passes through a hole formed at the left side of the brick at one stage of the brick, and passes through a hole formed at the right side of the brick at the next stage, and again at the next stage. It can be masonry in such a way as to pass through the hole formed on the left side of the passage, through the hole formed in the center of the brick at one stage of the brick, as shown in Figure 9c, and then through the joint between the brick and the brick at the next stage and then again It may be arranged to pass through a hole formed in the center of the brick at the stage. That is, the method of masonry may be any method that allows the fix 1 to penetrate in the vertical direction. However, the method of masonry is preferably made within the allowable thickness of the joint allowed by the masonry wall in consideration of the thickness of the fix 1 and the fix holder 2 and the maximum allowable thickness of the joint.

When building bricks, the work is carried out by the masons, who are not familiar with the use and construction of fixes and fix holders. It may be cumbersome to explain, and even if it is described, it is not desirable to work in a state where the construction is not familiar with the use of the tool. Therefore, masons do only minimal work on fixes and fix holders, and the rest of the work can be considered by trained workers who can professionally handle fix and fix holders. In other words, the work to be done is a way to professional dualize the work of masons and fix holder workers.

10 is a perspective view showing still another example of the fix holder used in the masonry wall reinforcement method of the present invention.

Compared with the fix holder of FIG. 2, the fix holder 2 of FIG. 10 has a difference in that the slit 24 is formed instead of the through hole 23 of the fix holder of FIG. 2. That is, one side of the fix holder 2 is provided with a pair of slits 24 formed in the shape of the end T of the fix holder 2 and opened in the longitudinal direction of the fix holder 2 by a length h. have. The slit 24 has a gap u enough to fit the wings 12 of the fix 1.

When the fix holder 2 of FIG. 10 is connected perpendicularly to the fix holder 2, the fix holder 2 penetrates the fix 1 through the through hole 23 as in the case of the fix holder of FIG. 2. Contrary to this, the fix 1 can be placed sideways at the open end T of the fix holder 2 so that the fix 1 can be positioned on the innermost side of the slit 24 via the slit 24. have. This method is more convenient for operation than inserting the fix 1 through the through hole 23 as shown in Figs. 2 and 3, in particular the fix holder 2 between the brick B and the brick B. The fix 1 can be connected vertically with respect to the fix holder 2 even when it is embedded in the joint, thereby providing convenience to the work.

FIG. 11 is a perspective view and a triangular perspective view of a cap used with the fix holder of FIG. 10, and FIG. 12 is a perspective view showing a fastening example of the fix holder of FIG. 10 and the cap of FIG. 11.

If you want to use the method of inserting the fix holder (2) in the joint between the bricks (B) and inserting the fix (1) through the slit 24, the joint mortar for the joint when embedding the fix holder (2) in the joint There is a need for a configuration that prevents the inside of the fix holder 2 through the slit 24 of the fix holder 2. Therefore, in this method, the fix holder 2 and the cap 4 which can be used as a set are used.

The cap 4 can be inserted into and detached from the end portion T in which the slit 24 is formed in the fix holder 2, and shields the slit 24 when inserted, thereby injecting mortar when injecting the joint of the brick wall. The slit 24 is prevented from flowing into the fix holder 2.

The cap 4 has a base portion 41 having a rectangular shape that is substantially long left and right, both side portions 42 having a substantially joint thickness formed on both sides of the base portion 41, and a slit 24 at the center of the base portion 41. And an approximately cylindrical insertion portion 43 inserted into the fix holder with a length h (see FIG. 11B) corresponding to the length h (see FIG. 10B), and the side portions 42 and the insertion portion. And a connecting portion 44 which connects 43 and has a thickness u (see FIG. 11B) corresponding to the spacing u (see FIG. 10) of the slit.

There are two fastening methods of the cap 4 and the fix holder 2, which are shown in FIG. First, reference is made to FIG. 12A. The slit 24 of the fix holder 2 with the cap 4 in a state in which the base portion 41 of the cap 4 is left and right aligned with the slit 24 of the fix holder 2 aligned to the left and right. ), The gap between the slit 24 of the fix holder 2 and the thickness of the connecting portion 44 of the cap 4 are equal to u, so that the connecting portion 44 of the cap 4 is the fix holder. It fits in the slit 24 of (2). The fix holder 2 may then be engaged with the cap 4 such that its end T reaches the base 41 of the cap 4. As a result of this coupling, the length h of the insertion portion 43 of the cap 4 is equal to the length of the slit 24 of the fix holder 2, so that the slit 24 of the fix holder 2 is the insertion portion. It is shielded by 43.

Another fastening method of the cap 4 and the fix holder 2 will be described with reference to FIG. 12B. The slit 24 of the fix holder 2 with the cap 4 in a state where the base portion 41 of the cap 4 is aligned vertically with the slit 24 of the fix holder 2 aligned to the left and right. When inserted into the forming portion, since the connecting portion 44 of the cap 4 interferes with the end T of the fix holder 2, unlike the above coupling method, the fix holder 2 has an end portion T of the cap ( It may be engaged with the cap 4 until it interferes with the connection 44 of 4). As a result of this coupling, the slit 24 of the fix holder 2 is shielded by the insert 43 with the innermost side opened by t. This is because, as shown in FIG. 11B, the height of the connecting portion 44 that interferes with the end T of the fix holder 2 is t. The opened innermost t part of FIG. 12B is a space for the fix 1 inserted in the direction perpendicular to the longitudinal direction of the fix holder 2 through the slit 24 (FIGS. 13E and 13F). Reference).

Hereinafter, an example of the reinforcement expansion / construction method of the masonry wall using the fix 1, the fix holder 2, and the cap 4 described above will be described.

FIG. 13 is a view illustrating a procedure of a masonry wall reinforcement expansion and contraction method using the fix of FIG. 1, the fix holder of FIG. 10, and the cap of FIG. 11.

First, as shown in (a), the inner wall (C) is already erected, and in the process of stacking bricks (B) on the outside, the bricks are stacked on the X1 th stage, and then joined as shown in FIG. 12A thereon. Put the cap (4) and the fix holder (2). At this time, the base portion 41 of the cap 4 or the end portion T of the fix holder 2 is located approximately around the corner of the brick B, and the base portion 41 of the cap 4 is long left and right. To be placed. Preferably, the thickness v of the base 41 of the cap 4 (see FIG. 11B) should approximately match the height of the joint between the brick and the brick.

The reason why the base 41 of the cap 4 is elongated is that, in the state where the fix holder 2 and the cap 4 are coupled as shown in FIG. 12A, the masonry is simply the base 41 of the cap 4. Just to align the left and right on the brick (B), the slit 24 of the fix holder (2) is to be placed on the brick (B) aligned in the left and right state.

Here, the fix holder 2 is positioned to pass over the hole BH of the brick B, and every fixed interval (for example, 5 to 6 units of the brick B to the left and right) along the circumference of the brick wall. Place a plurality.

In this state, as shown in (b), the bracket 3 is fitted in the position on the hole BH of the fix holder 2. The bracket 3 includes an elastic fastening portion 32 for fastening with the fix holder 2 and a through hole 31 formed at one side of the elastic fastening portion 32. The through hole 31 is in communication with the hole (BH).

Next, as shown in (c), the fix 1 is inserted in the vertical direction through the through hole 31 of the bracket 3. After inserting the fix 1, mortar is inject | poured into the hole BH of the brick B in which the fix 1 was inserted. Subsequently, the masonry positions the mortar so that the plurality of fix holders 2 placed on the brick B of the X1 th stage are embedded about two-thirds from the inner wall, that is, the slit (from the inner end of the fix holder 2). 24) Place mortar until before (see m1) and pile up brick (not shown) at the top. In this case, the holes formed in the bricks of the upper end are stacked so that the fixes 1 inserted into the brackets 3 can pass through them. Of course, the mortar is injected into the hole of the brick passing through. When a predetermined stage (for example, bricks 5 to 6) is stacked on the top of the X1 stage brick, the bricks are embedded while the fix holder 2 is embedded at regular intervals by repeating the above steps (a) to (c). I'm masonry. Here, in the coupling process of the bracket (3) and the fix (1), the fix (1) that has already been excreted from the lower end through the hole 31 of the bracket (3).

Here, it is apparent to those skilled in the art that even if the non-fixed-plated iron wire having irregularities is formed in the through hole 31 of the bracket 3, the fix holders 2 may be connected in the vertical direction. .

This is what masons can do.

After the mortar is hardened, professional workers are fixed to the inner wall.

In the masonry wall immediately before the workers work, the fix 1 connected through the bracket 3 of the fix holder 2 connects the fix holder 2 in the up and down direction, as shown in (c) of FIG. 13. The fix holder 2 is embedded in the joint between the bricks with the cap 4 covering the end portion T in the horizontal direction.

Figure 13 (d) is shown by omitting the brick stacked on top of the X1 stage. Referring to (d) of FIG. 13, the workers find the cap 4 that appears between the bricks, extract the cap 4, and then insert the drill into the end T of the fix holder 2 to insert the drill through the inner wall (the fix holder 2). The hole CH is drilled in C). The diameter of the hole CH is about 1.5 to 2 mm smaller than the diameter of the fixer 1 to be described later to be embedded in the inner wall C. Then, the fixer 1 is driven into the hole CH by using a tool (not shown) through the fixer 2. The fix holder 2 is now secured to the inner wall C now.

Next, as shown in (e), the fix 1 is pushed into the innermost part of the slit 24 through the slit 24 of the fix holder 2. In this way, the fix holders 2 are connected to each other in the left and right directions. It will be apparent to those skilled in the art that even if the slit 24 is used using a release-plated iron wire having irregularities instead of the fix 1, the fix holders 2 may be connected in the left and right directions.

Finally, as shown in (f), the cap 4 is now vertically inserted with respect to the end T of the fix holder 2 (as shown in FIG. 12B), and the mortar is not yet filled. Inject mortar into the mortar part (m2). By fitting the cap 4 here, mortar is prevented from entering the inside of the fix holder 2 through the slit 24.

Once the mortar has been injected, the cap 4 is finally removed.

Through this process, the fix holders 2 buried in the mortar of the bricks and tightly connected to the bricks are strongly connected to the inner wall C, and the fix holders 2 are also fixed to each other by the fixings 1 and the like in the vertical direction. It is connected.

Therefore, the wall masonry using the above fix, fix holder, cap, etc. is structurally solid.

The cap 4 fitted to the fix holder 2 in step (a) of FIG. 13 aligns the direction of the slit 24 of the fix holder 2 and at the same time (c) inside the fix holder 2. This prevents the mortar from entering, and in step (d) it makes it very easy for workers to locate the buried fix holder (2). In addition, the cap 4 fitted to the fix holder 2 in step (f) prevents mortar from flowing into the fix holder 2 and the fix holder 2 at the position indicates that the work has been completed. The state is an indicator. Therefore, the cap 4 used together with the fix holder 2 not only enables the internal space S of the fix holder 2 to serve as a vent, but also provides great convenience in operation.

The preceding masonry sequence was designed to allow masons from (a) to (c), and (d) to (f) to allow fix holders to work with fix holders who are not good at handling fix holders. The steps are taken to minimize the burden and hassle and to finish and maximize the work efficiency by those who can handle fix holders professionally. Of course, in this reinforcement method, the process of connecting the fix holder 2 in the vertical direction of the building (process shown in FIGS. 13B and 13C) may be omitted.

On the other hand, this reinforcement method can be used in the post-repair work of the masonry wall already completed. In this case, although it is difficult to connect the fix holder 2 in the up and down direction, it is possible to connect the fix holders 2 to each other in the circumferential direction of the building through the following process.

First, remove 1/3 of the joint to install the fix holder (2) along the perimeter of the building, and then fix the inner wall and fix the remaining 2/3 joint part from the position where you want to install the fix holder. Perforate 1 ~ 2mm larger than the diameter.

Next, an adhesive such as epoxy is applied to the outer surface of the fix holder and inserted into and fixed to the perforated portion of the joint. Of course, in this case, as shown in FIG. 13A in a state in which the cap 4 is coupled as shown in FIG. 12A, both side portions 42 of the cap 4 are arranged in the circumferential direction of the building so that the fix holder 2 is fixed. ), The slit 24 can be positioned accurately to both the left and right sides.

Once the fix holder is fully secured, it drills a hole for fixing the fix in the inner wall through the inside of the fix holder and drives the fix. Then, through the slit 24 formed at the rear end of the fix holder, a release-plated iron wire having another fix or irregularities is inserted in the vertical direction of the fix holder.

Then, the cap 4 is inserted into the rear end of the fix holder 2 as shown in FIGS. 12B and 13F, and then mortar is re-injected into 1/3 of the joint that was first removed.

Finally remove the cap (4).

Through such a process, it is also possible to reinforce and repair the already completed masonry wall using the fix holder 2 shown in FIG. 10.

In the above-described masonry reinforcement methods, in the case of the joint end where the fix holder 2 is installed, the end of the fix holder 2 is exposed by forming the joint into a depth of about 10 mm from the outer surface of the brick. While not deteriorating the appearance of the yin and yang can be harmonious in appearance and at the same time the fix holder (2) can easily check the position of the buried joint can be easy to follow-up management.

As described above, the masonry wall reinforcing method of the present invention can be reinforced reinforcement repair or reinforcement expansion and contraction by firmly fixing the fixation to the inner wall along the circumference of the building and connecting them to each other by means of a fix holder and other fixes. In particular, it is possible to reinforce only by fix, fix holder and bracket without needing many parts, which provides construction convenience to the construction worker, and is fixed integrally with mortar due to the appearance of the wing of the fix and the wing receiving part of the fix holder. In addition, a gap may be provided between the wing of the fix and the wing receiving portion of the fix holder, thereby preventing corrosion and cracking due to interference overcoming and aeration due to a difference in thermal expansion.

The present invention is not limited to the described embodiments, and various modifications and changes can be made to those skilled in the art without departing from the spirit and scope of the present invention. Such modifications or modifications may be made to the present invention. It belongs to the claims of the.
