The present invention relates to a method of reinforcing a masonry wall piled up externally, and more particularly, to remove some of the external bricks of the masonry wall, the portion of the masonry wall using a reinforcing bracket, etc. It relates to a masonry wall reinforcement method to reinforce the strength of the masonry wall by transmitting.

In general, when stacking the external stucco of masonry walls, concrete jaws or steel brackets are installed or fixed on the main structure for each floor, and then the bricks are stacked on the upper part of them so that the concrete jaws or steel brackets bear the vertical load of the stucco bricks. It was constructed to be delivered to the structure.

However, if the verticality does not match when constructing the concrete structure, the external bricks are stacked without the brackets, so the flaw of the masonry subsidence, cracking, and batching occurs due to the self-loading of the bricks. It was often the case that exterior stucco bricks were dropped off, causing damage to parked vehicles or accidents for pedestrians.

In addition, the lintel portion immediately above the window had a problem that the crack or dropout of the brick frequently occurs due to structural fragility.

The present invention is to solve the above-mentioned problems, and in particular, to provide a reinforcing method for reinforcing the lintel portion where the defect occurs.

It is an object of the present invention to provide a reinforcement method that can firmly reinforce an exterior masonry wall in which cracks have occurred.

Another object of the present invention is to provide a masonry wall reinforcing method for improving the durability of the exterior masonry wall by effectively distributing the load of the exterior masonry wall to the bearing wall side.

Another object of the present invention is to provide a masonry wall reinforcement method to prevent the bricks of the lintel portion from leaving by fixing the bricks stacked on the lintel portion to the angle fixed to the bearing wall.

In order to achieve the above object, the present invention provides a masonry wall reinforcement method for replacing and reinforcing a part of a masonry wall in which a crack has occurred.

Reinforcing pin press-fit step of connecting the masonry wall and the bearing wall using a reinforcement pin on the top of the brick replacement section; A replacement brick removing step of removing the replacement section brick by crushing the joint of the replacement section brick; Reinforcing bracket installation step of fixing the reinforcing bracket to the bearing wall in accordance with the lower surface of the upper masonry wall located in the upper portion of the replacement section;

An angle and a hanger installation step of fixing the bricks stacked on the lintel by using an angle and a hanger; And a finishing masonry step of stacking bricks on the replacement section and stacking bricks on the replacement section.

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

The reinforcement work of the masonry walls begins with selecting the sections to be replaced and then fixing the top of the sections to the bearing walls.

1 is a perspective view and a cross-sectional view showing a state drilled with an electric drill (D) on the upper end of the brick replacement section, Figure 2 is a state in which the masonry wall is fixed to the bearing wall by pressing a reinforcement pin into the through hole drilled by the electric drill. Perspective and sectional views.

As shown, the wall of the building consists of a masonry wall forming an exterior and a bearing wall I supporting the building therein. The drawing shows the lintel part on the upper side of the window (W) where defects frequently occur, and shows a state in which five stages (marked by hatching) on the upper side of the window (W) are selected as a replacement section.

When the replacement section is selected, drill the through hole (H) using the electric drill (D) at a predetermined interval (approximately five bricks) to the brick (B1) immediately above the replacement section, and press-fit the reinforcement pin (P) in the shape of a screw. do. The reinforcement pins P may be additionally installed at the bottom of the upper masonry wall BU from the uppermost part B1 to 4 to 6 steps. In this case, the installation position P1 is installed at the center of the B1 reinforcement pins P. It is desirable to.

Since the reinforcement pin (P) supports the load of the inverted triangle shape due to the structural characteristics of the masonry wall, the reinforcement pin (P) is additionally pressed into the portion where the loads supported by the reinforcement pins (P) located below the B1 end overlap. If this happens, the load applied to the reinforcement pins installed in the B1 stage is reduced, resulting in the effect of load distribution. The number of rows for pressing the reinforcement pins is determined according to the height and load of the upper masonry wall of the replacement section.

When the reinforcement pins P are press-fitted in this way, the masonry wall BU of the upper portion of the replacement section is connected through the bearing wall I and the reinforcement pins P, so that the masonry wall of the upper portion BU is removed even if the brick of the replacement section is removed. ) Will not collapse. In addition, since the reinforcement pins (P) remain unremoved even after replacement construction, the load of the upper end of the replacement section is continuously distributed to the bearing wall (I), resulting in a full load due to the weight of the masonry wall. The occurrence of can be prevented.

The diameter of the through hole (H) is smaller than the diameter of the screw-shaped reinforcing pin (P) so that the reinforcing pin (P) can be firmly fixed to the through hole.

3 is a perspective view and a cross-sectional view showing a state in which the brick of the replacement section is removed and the reinforcing bracket is installed.

As shown, since the reinforcing pin P is inserted to connect the upper masonry wall BU to the replacement section with the bearing wall I, the upper masonry wall BU does not collapse even when the brick of the replacement section is removed. Can be maintained. The replacement section brick is removed by crushing the joint using a tool such as a grinder, and then removing the brick in the replacement section. The shredding of joints and wedges at regular intervals ensure that the broken parts of the joints are kept at regular intervals so that the blade of the grinder is not caught between the joints.

As shown, the lower end of the replacement section upper masonry wall (BU) fixed using the reinforcement pin (P) is supported by the reinforcement bracket 100 once again. The reinforcing bracket 100 has a substantially L-shaped cross section so that the vertical portion is fixed to the bearing wall I so that the horizontal portion supports the lower end of the masonry wall in the upper portion of the replacement section. The reinforcement bracket 100 is installed at regular intervals and connects each reinforcement bracket 100 with a wire member 200 so that the reinforcement bracket 100 and the wire member 200 support the bottom of the entire B1 end. Provides a structure to

Figure 4 is an exploded perspective view showing the structure of the reinforcing bracket used in the present invention.

The masonry wall reinforcement bracket 100 used in the present invention is composed of an L-shaped main bracket 110 and an auxiliary bracket 120 coupled to the main bracket 110.

The main bracket 110 is composed of a vertical portion 112 attached to the bearing wall (I) and a horizontal portion 114 coupled with the auxiliary bracket 120, the vertical portion 112 and the horizontal portion 114 is Combined to have approximately L-shaped cross sections. The horizontal portion 114 is formed with a fastening hole 115 formed in the longitudinal direction, the length adjustment hole 122 corresponding to the fastening hole 115 is also formed in the auxiliary bracket 120.
