Description

{Apartment Masonry Wall Reinforcement Device}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a masonry wall reinforcing apparatus for a masonry used for binding an inner wall and a brick, and more particularly to a masonry wall reinforcing apparatus for a masonry which improves the binding force between the inner wall and the brick,

Generally, the masonry wall which is made by stacking the bricks in a certain pattern is made to contact with the mortar. Since it is convenient to carry to the work site and is easy to handle, it is widely applied to the wall construction in which the load is not applied after the frame construction. There is also an advantage that it is possible to burrow various pipe easily because it is simpler than the reinforced concrete when grooving or perforating the surface of the wall.

When the heat insulating material is disposed between the wall and the inner wall, it is difficult to join the brick with the inner wall with mortar, so that the wall is connected to the inner wall using the reinforcing device.

An example of such a conventional wall reinforcing apparatus is shown in Figs. 1 and 2. With reference to this, a wire-fitting plate 1 having a concave-convex cross-sectional shape having grooves 1a, 1b, 1c and protrusions 2 formed continuously in the longitudinal direction is placed on the bricks 3 The ends of the wire strands 4 are inserted into the wire fitting plates 1 through the hooks 7 of the brackets 6 fixed to the inner wall 5 by spreading the end portions of the dried wire strands 4 in a loop form, 1b formed on the brick 3 and the straight wire 8 is horizontally inserted into another groove 1c formed in the wire fitting plate 1 and then the mortar is uniformly placed on the brick 3 So that the wire 8, the wire-fitting plate 1, and a part of the steel wire loop 4 are covered with a thickness.

However, in the conventional technique, since the wire loop 4 and the wire 8 are loosely fitted in the grooves 1a, 1b, and 1c formed in the wire-fitting plate 1, 4 and the wire 8 are frequently detached from the grooves 1a, 1b, 1c, and there is a problem that it is inconvenient to construct them carefully in consideration of this.

Particularly, when the bricks 3 are covered with mortar, the joint portions between the wire rope 4 and the wire 8, which are fitted in the grooves 1a, 1b and 1c of the wire fitting plate 1, It is very difficult to confirm the departure site. Also, when it is constructed in a detached state, there is a problem that it leads to a construction failure.

In addition, since the end of the steel wire loop 4 must be widened when the steel wire loop 4 is hooked to the bracket 6, the operation is very inconvenient and the working time becomes long. There is a problem in that the engagement plate 7 formed on the bracket 6 is easily bent into an arc shape and the engagement is loosened.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a masonry wall reinforcing apparatus for masonry houses which can firmly fix a brick to an inner wall.

In order to accomplish the object of the present invention, there is provided a masonry wall reinforcing apparatus for a dwelling, comprising: a pair of vertical guides formed in parallel with each other at left and right edges of a wall surface fixing bracket, A pair of coupling bars symmetrically joined to each other in a horseshoe shape and connecting the wall surface fixing bracket to the bricks; A brick-tightening portion formed at the front of the coupling bar and closely attached to the upper surface of the brick; A twisted twisted portion formed at a rear end of the brick tight portion; A pair of corrugated bands laminated and joined to the upper surface of the brick-tightened portion, each having a plurality of steel wire insertion grooves; A steel wire retaining piece formed by partially cutting the steel wire insertion groove from a side edge thereof and inclining the lower end thereof upward; A rear surface tightening part formed in a direction opposite to the rear end of the coupling bar and closely attached to an outer surface of the vertical guide part; And a locking jaw which is bent rearwardly from the rear close contact portion and hooked to an end of the vertical guide portion. A curling joint joined to each other by being looped from the engaging jaw and spaced apart from a front surface of the wall surface fixing bracket; And corner engaging portions which are bent in a trapezoidal shape in mutually opposite directions from the curling joining portions and are in close contact with the front surface of the wall surface fixing bracket and whose ends are caught at the inner corners of the vertical guiding portions.

The present invention is characterized in that an outward upward bent portion bent upward from a front side end portion of the brick tight contact portion; A notch formed at an upper end of the outer upwardly bent portion; An inner upwardly bent portion that is bent upward from a front side end portion of the pleated band and overlaps with a rear side of the outer upwardly bent portion; A front engaging piece which is bent horizontally at the upper end of the inner upwardly bent portion and then bent downward again so as to be engaged with the notch portion; A downward bent portion bent downward from left and right edges located at the rear of the corrugate band and closely engaged with the left and right side surfaces of the brick tight portion; A "U " -shaped brick latching portion which is engaged with a brick hole formed in the brick; A slide unit horizontally extending from one upper end of the brick latch unit and slid in a lateral direction in a state of being inserted into two steel wire insertion grooves positioned on a straight line in the wrinkle band to adjust a latching position of the brick latch unit; And a rotation preventing portion extending parallel to the same direction as the slide portion from the other upper end of the brick retaining portion and preventing the rotation of the brick retaining portion while being inserted into a steel wire insertion groove different from the steel wire insertion groove into which the slide portion is inserted have.

As described above, according to the present invention, when the coupling bars joined to each other are coupled to the wall surface fixing bracket, since the rear surface contact portion, the engagement protrusions and the corner engagement portion are aligned with the upper ends of the vertical guide portions, The connection of the bar and the wall fixing bracket can be performed very quickly and conveniently.

When a tension is applied to the coupling bar in a direction away from the inner wall due to an earthquake or other external force, the vertical guide portion receives a force in a horizontal direction perpendicular to the longitudinal direction, Since it is bent so as to have a cross section, the resistance against bending is greatly increased compared with the conventional one.

There is an effect that the steel wire can be prevented from coming off because the steel wire is hooked to the steel wire holding piece when the steel wire is inserted into the steel wire insertion groove formed in the corrugated band bonded to the brick tight portion.

When the front connecting piece formed on the inner upwardly bent portion of the wrinkle band is hooked on the notched portion formed on the outer upward bent portion in a state where the inner upwardly bent portion formed in the wrinkle band is in close contact with the outer upwardly bent portion formed in the brick- It is possible to prevent the front side end portion from flowing in the front, back, left, and right directions, thereby making it possible to more conveniently and quickly position the pleated band.

If the downwardly bent portions formed on the rear side of the wrinkle band are brought into close contact with the both side faces of the brick tightening portion, the rear end of the wrinkle band can be prevented from flowing in the lateral direction, .

Since the rear surface of the corner engaging portion, which is caught by the inner corner portion of the vertical guide portion, is also brought into close contact with the front surface of the wall surface fixing bracket, there is an effect that a more firm bonding force can be obtained.

There is an effect that the connection of the coupling bars can be made more firmly by the curling joints which are rolled in the form of a loop and brought into close contact with each other and then joined together.

Since the rear surface of the curling joint is spaced from the front surface of the wall surface fixing bracket, it is possible to prevent the rear joint portion of the curling joint from interfering with the front surface of the wall surface fixing bracket.

Since the brick hole engagement position of the brick engagement portion can be adjusted while being moved in the lateral direction by the slide portion, there is an effect that the operation of engaging the brick engagement portion into the brick hole can be facilitated.

There is an effect that the brick latching portion can be prevented from rotating around the slide portion by the rotation preventing portion.

Furthermore, in the present invention, since the steel wire retaining piece has an elastic force, when the steel wire is to be separated from the steel wire insertion groove, the steel wire retaining piece can be easily separated from the steel wire insertion groove by pushing the steel wire retaining piece outwardly by using an elongated tool.

It is possible to facilitate the spot welding of the corrugated band and the brick-welded portion by using flat portions provided on the front and rear sides of the corrugated band.

When the lower end of the corrugated band is welded to the brick-tightened portion when the corrugated band and the brick-tightened portion are joined to each other, it is possible to prevent the corrugated band from being deformed while being stretched in the longitudinal direction, .

After the brick hooking portions 70 and 80 are caught in the brick holes, the position adjusting operation is stopped and the brick tightening portions 32 and 42, the folding bands 50 and 60 positioned on the brick 10, The steel wire 12, the brick retaining portions 70 and 80, the slide portions 72 and 82 and the rotation preventing portions 74 and 84 are covered with a brick bonding agent such as mortar, (14) are coupled through the coupling bars (30, 40).

The steel wire 12 inserted in the steel wire insertion grooves 51 and 61 is pressed against the steel wire retaining pieces 51 and 61 by a force in a direction in which the brick 10 is moved away from or close to the inner wall 14 due to an earthquake or other external force, 52) 62, the binding between the steel wire 12 and the brick 10 is strengthened.

The tensile force applied to the coupling bars 30 and 40 in the forward and backward directions is applied to the corner engaging portions 37 and 47 and the vertical guiding portion 22 engaged with the inner corner portions of the vertical guide portions 22 and 24, And the right and left horizontal swings of the coupling bars 30 and 40 are supported by the rear face contact portions 34 and 44 which are in close contact with the front face of the vertical guide portions 22 and 24, (35) (45) which are engaged with the engagement protrusions (35).

Since the corner engaging portions 37 and 47 are also supported on the front face of the wall surface fixing bracket 20, the supporting force is further improved. As shown in the enlarged view of FIG. 4, the end portions of the curling joining portions 36 and 46 The welding beads W3 and W4 formed on the rear contact portions 34 and 44 can prevent the rear contact portions 34 and 44 from spreading between the engagement protrusions 35 and 45 while the opened curling joint portions 36 and 46 are opened Can be prevented.
