Description
The present invention relates to a wedge anchor for reinforcing a coarse wall and a method for reinforcing a coarse wall using the wedge bolt. More particularly, the present invention relates to a wedge bolt, a first wedge portion inserted into an end portion of the wedge bolt, Wherein the reinforcing wedge anchor is configured such that the outer periphery of the first wedge portion which is subjected to the urging force by the advancement of the wedge bolt bulges and is brought into close contact with the inner periphery of the through- Reinforcing wedge anchor, and a method for reinforcing a masonry wall using the wedge anchor.
Generally, in order to form the exterior decoration of the masonry wall, a concrete jaw or a steel bracket is installed or fixed on the body structure for every layer, and then a stucco brick is stacked on the upper part of the main body structure so that a concrete jaw or a steel bracket pays a vertical load of the stucco, To be transferred to the structure.
However, when the vertical structure is not matched during the construction of the concrete structure, the brackets are omitted and the exterior stucco bricks are stacked. As a result, the settlement and cracking of the masonry wall due to the stucco brick load, Exterior stucco bricks fell off, which often caused breakage of the parked vehicle or safety accidents of passers-by.
Also, the upper part of the lintel, which is just above the window, has a problem in that cracks or bricks are frequently detached due to structural weakness.
The conventional method proposed for solving the above problem is a method of reinforcing a coarse wall of Korean Registered Patent No. 10-628510 (2006.09.26.), As shown in FIG. 1, in which a part of the coarse- A reinforcing fin press-fitting step of selecting a brick replacement section and connecting the masonry wall and the proof wall using a reinforcing fin on the brick replacement section; Replacement brick removal step of breaking brick joints to remove replacement bricks; A reinforcing bracket mounting step of fixing the reinforcing bracket to the load bearing wall body in conformity with the lower end face of the upper furnace wall located at the upper end of the replacement section; An angle and a hanger installation step of hanging a brick built up on the upper part of the window by hanging using an angle and a hanger; And a finishing step of finishing the brick by sequentially stacking the bricks on the angle and filling the replacement section with new bricks.
However, the conventional method for reinforcing a coarse wall has a problem that a sufficient fixing force can not be exerted on the reinforcing fin by simply pressing the reinforcing pin between the coarse wall and the load bearing wall in the reinforcing pin press-in step.
That is, when the reinforcing fin is inserted between the masonry wall and the load bearing wall, the reinforcing pin inserted due to external factors such as vibration or shock generated during the process of removing the masonry wall to be repaired is released, There is a problem that the function is lost.
In addition, it is possible to prevent the occurrence of overburden phenomenon in the existing masonry wall due to external factors such as vibration or shock generated during the maintenance process with the reinforcing pin inserted, or in the case of severe masonry, There is a problem that it is dropped.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a reinforcing wedge anchor comprising a wedge bolt, a first wedge portion inserted into an end portion of the wedge bolt, and a gap holding portion inserted into the wedge bolt, So that the outer peripheral edge of the first wedge portion, which is subjected to the urging force by the advancement of the wedge bolt, can be brought into close contact with the inner circumferential edge of the through-hole of the force-proof wall while the outer peripheral edge of the wedge bolt bulges to maintain a firm fixing force, and And to provide a method of reinforcing a masonry wall.
Another object of the present invention is to provide a reinforcing wedge anchor capable of maintaining a firm fixing force by forming a second wedge portion on the reinforcing wedge anchor and by pressing the outer periphery of the second wedge portion by the urging force of the wedge bolt, And a method of reinforcing a masonry wall using the wedge anchor.
It is a further object of the present invention to provide a reinforcing wedge anchor which is inserted into a plurality of through holes formed in a masonry wall so that the existing masonry wall stone is prevented from falling out during repairing of the masonry brick, The present invention provides a wedge anchor for reinforcing a masonry wall and a method for reinforcing a masonry wall using the same.
It is still another object of the present invention to provide a wedge anchor for reinforcing a reinforcing wedge anchor that is inserted into the through hole and further includes an adhesive injecting step for injecting an adhesive into the through hole, Method.
It is a further object of the present invention to provide a method of manufacturing a reinforcing wedge anchor, which further includes a through-hole finishing step of inserting a finishing material into the through-hole into which the reinforcing wedge anchor is inserted so that the foreign material and the through- A wedge anchor for reinforcing a masonry wall, and a masonry wall reinforcing method using the same.
In order to accomplish the object of the present invention, there is provided a wedge anchor for reinforcing a masonry wall reinforcement to prevent dropping of an existing masonry wall during a repair process when repairing the masonry wall, A wedge bolt having a groove formed therein, a wedge formed at an end of the fixed shaft, and a wedge bolt formed at an end of the fixed shaft; A first wedge portion having a receiving space formed on an inner side thereof so as to insert an end of the wedge bolt, a fastening portion fastened to the spiral portion at one side, and an extension guide hole for facilitating expansion by an urging force on an outer circumference; And a gap retaining portion inserted into the fixing shaft of the wedge bolt to press the first wedge portion by a pressing force advancing by the rotation of the wedge bolt so that a fixed fixing force is exerted on the periphery of the through- .
In the present invention, the wedge anchors for reinforcing a masonry wall are inserted into the wedge bolts and are partially cut at one side so that they are swelled up by the pushing force acting by advancing the wedge bolts and are brought into close contact with the inner periphery of the through holes of the rough bricks And a second wedge portion on which at least one second wedge is formed.
In the present invention, it is preferable that at least one first wedge is provided on the outer circumference of the first wedge portion so as to be brought into close contact with the inner circumferential edge of the through-hole of the proof wall to swell due to the urging force of the wedge bolt, Do.
