The above step is referred to as the brick removing step (S1), and FIG. 2 shows that the uppermost bricks T ₁ and T ₂ and the lowermost bricks F ₁ and F ₂ are removed in this step. As shown in FIG. 2, the positions where the uppermost bricks T ₁ and T ₂ and the lowermost bricks F ₁ and F ₂ are removed are indicated by T ₁ ′, T ₂ ′ and F ₁ ′, F ₂ ′. Will be produced. The auxiliary support 1 to be described later supports the upper and lower masonry walls Hb and Lb through the space formed by the upper and lower pairs on the left and right sides.

When the brick removal step (S1) is completed, the auxiliary support installation step (S2) proceeds.

Prior to the description of the auxiliary support installation step S2, the auxiliary support 1 used in the present invention will be described with reference to FIGS. 10 to 14.

As shown in FIG. 10, the auxiliary support 1 for the reinforcement work of the masonry wall according to the present invention includes a support pillar 10 extending in a longitudinal direction and formed of a length-adjustable structure, and an upper / lower support bracket ( 20, 30 and the fixing member 40. FIG. 11 shows the support column 10, FIG. 12 shows the upper and lower support brackets 20 and 30, and FIG. 13 shows the support member 40, respectively.

First, the support column 10, as shown in Figure 11, consists of a support member 12 and the length adjusting member (14). The support member 12 is formed in a long hollow cylindrical shape extending in the longitudinal direction, the inner thread is formed with a female thread. One end of the support member 12 (upper end in the drawing of the present invention) is opened to screw with the length adjusting member 14, which will be described later, and the inlet portion is the thickness of the overall length of the support member for strength. A thicker reinforcement member is further formed. The other end of the support member (lower end in the drawing of the present invention) is formed with a hinge hole (H) for hinge engagement with the lower support bracket (30).

In addition, the length adjusting member 14 has a diameter corresponding to the inner diameter of the support member 12 and is formed in a cylindrical shape long in the longitudinal direction. In addition, the male thread is formed on the outer circumferential surface of the length adjusting member 14, and the length is adjusted by screwing with the female thread and the thread formed on the inner circumferential surface of the support member 12. In addition, one end (the upper end in the drawing of the present invention) of the length adjusting member 14 is formed with a hinge hole (H) to hinge the upper support bracket (20).

An upper support bracket 20 and a lower support bracket 30 are hingedly attached to upper and lower portions of the support pillar 10 formed of the support member 12 and the length adjusting member 14, respectively.

Next, the upper and lower support brackets 20 and 30 will be described with reference to FIG. 12.

The upper support bracket 20 is formed of a plate-shaped main plate 21 having a predetermined length in the lateral direction, as shown in Fig. 12A, and on one side The connection hole 27 for passing and connecting the fixing member 40 mentioned later is formed. The connection hole 27 does not serve to fix the fixing member 40 to the upper support bracket 20. Moreover, since the outer circumferential surface of the fixing member 40 is formed of a male thread, the fixing member 40 It is preferable that it is formed to have a tolerance that is larger than the diameter. The other side of the main plate 21 is provided with a support plate 22 for directly contacting and supporting the brick to be supported (in the case of the present invention, A brick shown in FIG. 1). The support plate 22 is preferably rotatably formed by hinge coupling, rather than being fixedly attached to the upper support bracket 20 in order to apply to changes in various working environments during reinforcement work. The hinge structure 23 used in the present invention may be formed of a hinge structure commonly used in the art.

In addition, the upper support bracket 20 is perpendicular to the main plate 21, a pair of engaging walls 24 extending in the longitudinal direction (lateral direction) of the main plate 21 is formed, the pair of Hinge holes H 'are formed at predetermined positions of the engaging wall 24, respectively. The periphery of the hinge hole H 'formed on the coupling wall 24 is formed to be thicker than the overall thickness of the coupling wall 24, that is, to form a boss to form the edge of the hinge hole H'. It is preferable to form to reinforce. In addition, the interval of the pair of coupling wall (H ') is the length adjustment for the hinge coupling with the hinge hole (H) formed in one end of the length adjusting member 14 (upper end in the drawing of the present invention). It is preferable that they are formed at intervals that can accommodate the diameter of the member 14. Since the outer circumferential surface of the length adjusting member 14 is formed of a male thread, it is preferable that the length adjusting member 14 is formed with an allowable tolerance so that the length adjusting member 14 is easily interposed, but the diameter of the length adjusting member 14 and the coupling If the distance between the walls 24 is large, a large load is applied to the fixing pins hinged, so that it is preferable that the wall 24 be formed to generally correspond to the diameter of the length adjusting member 14.

Further, a reinforcing member 25 is further formed on the lower surface of the main plate 21 of the upper support bracket 20 to reinforce the main plate 21. In the embodiment of the present invention, the reinforcing member 25 is formed in a predetermined shape between the coupling walls 24, but the reinforcing member 25 is not limited to being formed between the coupling walls 24.

In addition, since the structure of the lower support bracket 30 shown in FIG. 12 (b) is formed in almost the same configuration as the upper support bracket 30, the detailed description thereof will be omitted. However, the pair of coupling walls 24 and the reinforcing member 25 formed on the lower surface of the upper support bracket symmetrically with the upper support bracket 20 are a pair of coupling walls 34 on the upper surface of the lower support bracket 30. ) And the reinforcing member 35 is formed, and the hinge structure 23 formed on the upper surface of the upper support bracket 20 and the support plate 22 are formed by the hinge structure on the lower surface of the lower support bracket 30. 33) is formed and has a support plate (32).

Next, the sequence of joining the auxiliary support for reinforcement work of the masonry wall according to the present invention will be described with examples.

First, a hinge hole (H) formed at one end of the length adjusting member (14), which is the upper portion of the support column (10), and a hinge hole (a) of a pair of coupling walls (24) formed at the bottom surface of the upper support bracket (20) H ') is arranged in a row and hinged to the fixing pin 50, the washer 51 and the release prevention pin (52). In addition, a hinge hole H formed at the other end of the support member 12, which is a lower portion of the support pillar 10, and a hinge hole H of the pair of coupling walls 34 formed on the upper surface of the lower support bracket 30. ') Arranged in a row and hinged to the fixing pin 60, the washer 61 and the release prevention pin (not shown). At this time, the support plate 22 provided in the upper support bracket 20 and the support plate 32 provided in the lower support bracket 30 are coupled to face each other.

In addition to the above combination, the fixing member 40 shown in detail in FIG. 13 is interposed through the connection holes 27 and 37 formed at one end of the upper and lower support brackets 20 and 30, and the upper and lower portions are connected to each other. By adjusting the length of the nuts (42, 44), to fix a section of the masonry wall to be constructed. The fixing member 40 has a predetermined diameter and is formed in a cylindrical shape long in the longitudinal direction, the male thread is formed on the outer peripheral surface. Nuts 42 and 44 screwed to the upper and lower ends of the fixing member 40 are female threads formed on the inner circumferential surface thereof to be screwed with male threads formed on the outer circumferential surface of the fixing member 40. It is not limited. In the present invention, but shown a circular nut, it is also possible to facilitate the operator's convenience, such as a butterfly nut (butterfly nut).

Next, the auxiliary support installation step (S2) for installing the auxiliary support (1) configured in this way to the masonry wall will be described. 3 to 4 show the step of installing the auxiliary support used in the present invention on the masonry wall. However, in order to clearly and clearly show the present invention, the assembly configuration of the auxiliary support provided on the right side in the drawings is omitted. However, this is an auxiliary support having the same structure as the auxiliary support installed on the left side in the drawing is assembled in the same way and attached to the masonry wall.

In order to apply the auxiliary support 1 configured as described above to the brick replacement portion Db, as shown in FIG. 3, first, the length of the support pillar 10 is extended to the length adjusting member 14. The length adjusting member 14 or the supporting member 12 is rotated to extend the section length selected as the brick replacement portion Db. One end of the length adjusting member 14 is provided with an upper support bracket 20, and the other end of the support member is provided with a lower support bracket 30, the upper / lower support brackets (20, 30) are assembled The length may be adjusted while the upper and lower support brackets 20 and 30 are separated. However, since the fixing member 40 is not possible to adjust the length if it is assembled at this stage, the support pillar 10 is extended to a predetermined length and then coupled in the auxiliary support fixing step S4 described later.

In the same manner as described above, the support column is connected to the lower surface Tf ₁ of the upper masonry wall Hb, which is a direct support surface at the brick replacement portion Db, and the upper surface Ff ₁ of the lower masonry wall Lb. The support plates 22 and 32 of the upper support bracket 20 and the lower support bracket 30 respectively extend to be in contact with each other. That is, the upper support plate 22 extends near the bottom surface Tf ₁ of the upper masonry wall Hb, and the lower support plate 32 extends near the upper surface Ff ₁ of the lower masonry wall Lb.

This step is called the auxiliary support installation step (S2) and is shown in FIG.

Next, in the support column 10 having the upper and lower support brackets 20 and 30 extended in length as described above, a connection hole 27 formed in one end of the upper and lower support brackets 20 and 30. The upper nut 42 and the lower nut 44 are screwed to the upper and lower ends of the fixing member 40, respectively, by passing the fixing member 40 through the fixing member 40, and the auxiliary supporting member together with the supporting pillar 10. It consists of (1).

As shown in FIG. 5, the auxiliary support 1 configured as described above rotates the upper / lower nuts 27 and 37 in the tightening direction Cd to replace the auxiliary support 1 with the brick replacement portion Db. The lower surface Tf ₁ of the upper masonry wall Hb and the upper surface Ff ₁ of the lower masonry wall Lb are fixed to each other. At this time, when tightening the upper and lower nuts 42, 44, it is preferable to evenly tighten, so that the load is applied evenly over the entire auxiliary support (1).

As described above, the operation of installing and fixing the auxiliary support 1 to the brick replacement portion (Db) is as follows.

Referring to FIG. 14, first, the support pillar 10 in a state in which the upper support bracket 20 and the lower support bracket 30 are coupled is extended in the longitudinal direction D ₁ of the masonry wall of the section in which the brick is to be replaced. . In the extending method, the length adjustment member 14 hinged to the upper support bracket 20 may be rotated to extend in the longitudinal direction. After extending approximately the length of the masonry wall to be constructed (in the embodiment of the present invention between A ₁ brick and B ₁ brick), and then rotate the upper nut 42 and the lower nut 44 in the tightening direction to the upper support plate ( 22) Ensure that the lower support plate 32 is secured to the A ₁ brick and to the B ₁ brick. This is because the upper support bracket 20 operates on the principle of the lever centering on the fixing pin 50 by tightening the upper nut 42. That is, since the upper support bracket 20 is rotatable in the R ₁ direction with the fixing pin 50 as the axis, the _{one end} of the upper support bracket 20 is lowered down on the line D ₂ by tightening the upper nut 42. For this reason, the other end of the upper support bracket 20, that is, the portion provided with the support plate 22 goes up in the direction of A ₁ brick and is in firm contact with each other. In addition, the upper support plate 22 is also connected to the upper support bracket 20 by the hinge structure 23, so that the plane of the support plate 22 is kept horizontally in contact with the A ₁ brick firmly.

Also in the lower support bracket 30, similarly to the upper part, by tightening the lower nut 44, the lower support bracket 30 rotates in the R ₂ direction about the fixing pin 60 of the lower support bracket 30, thereby lowering the support bracket 30. One end of the rises, and as a result, the other end of the lower support bracket 30 descends in the direction of B ₁ brick, and the lower support plate 32 is also connected to the lower support bracket 30 by the hinge structure 33. , While the lower support plate 32 is kept horizontal, it is in firm contact with the B ₁ brick.

3 to 4, the right side auxiliary support has been omitted for the sake of brevity and clarity, but the installation of the right side support is the same as the installation of the left side support. That is, reference numerals A ₁ -A ₂ , B ₁ -B ₂ , T ₁ -T ₂ , T ₁ '-T ₂ ', F ₁ '-F ₂ ', Tf ₁ -Tf ₂ and Ff ₁ -Ff ₂ Corresponding to each. This is the same also in description mentioned later.

As described above, the auxiliary support 1 is firmly fixed, and can be safely performed in the next step of removing the replacement brick (S4).

After performing the auxiliary support fixing step (S3), to remove the bricks to be replaced of the replacement brick portion (Db). As shown in FIG. 6, since the auxiliary support 1 is connected to the auxiliary support so that the load of the upper masonry wall Hb is applied to the lower masonry wall Lb, the bricks of the brick replacement portion Db are removed. Even if the upper masonry wall (Hb) can be maintained without falling down. Removal of the replacement section bricks (Db) is made of a bangsing to crush the joint using a tool such as grinder, and then to remove the bricks of the replacement section.

This step is called a replacement section brick removal step (S4). At this time, when removing the bricks of the brick replacement portion (Db) it is preferable to remove the bricks by crushing the joint of the above-described method, but may be removed by other methods commonly used in the art. However, as described above, it should be removed in a manner that does not affect the secondary support (1) that is fixed.

5 to 6 shows the auxiliary support 1 is installed one by one left / right, it is preferable to use an appropriate number of auxiliary support 1 according to the length of the replacement section.

As described above, after removing all the bricks to be replaced, a brick filling step S5 of stacking new bricks is performed. After all the bricks of the brick replacement portion Db are removed, the section is cleaned in a conventional manner in the art, and as shown in FIG. 7, a new brick is formed by injecting mortar to form a joint. By stacking them, they create masonry walls made of new bricks.

This step is called brick filling step (S5).

As shown in Fig. 6 or 7, after forming the masonry wall with new bricks in the brick replacement portion (Db) except for the portion where the support plates 22, 32 of the auxiliary support 1 is interposed, The upper masonry wall in which the auxiliary support 1 was removed from the brick replacement portion Db while the mortar was hardened to some extent, and the remaining empty space, that is, the upper support bracket 20 of the auxiliary support 1 was interposed. space below the bottom surface of the _{(Hb) (T 1 ',} T 2') and the auxiliary support (1), the lower support bracket 30 is disposed lower masonry wall (Lb), the top surface above the space (F ₁ ', F of which was the Finish the reinforcement of the brick replacement part (Db) by putting new bricks in ₂ ').

When removing the auxiliary support 1, in the opposite direction of the auxiliary support fixing step S3, the upper nut 42 and the lower nut 44 provided at the upper and lower ends of the fixing member 40 are loosened (the tightening direction). The upper and lower support plates 22 and 32 are rotated in a direction opposite to Cd, so that the upper and lower surfaces Tf ₁ and Tf ₂ of the upper masonry wall Hb and the upper surface Ff ₁ of the lower masonry wall Lb. , Ff ₂ ).

This step is called an auxiliary support removing step (S6), and after removing the auxiliary support (1) by filling the new bricks in the empty space (T ₁ ', T ₂ ', F ₁ ', F ₂ '), respectively Finish the reinforcement of the brick replacement part. 9 shows an masonry wall filled with new bricks in T ₁ ′, T ₂ ′, F ₁ ′ and F ₂ ′. This step is referred to as finishing masonry step (S7).
