Description

Masonry Wall Binding Device}

The present invention relates to an architectural masonry wall binding device used to bind an interior wall and a masonry wall, and more specifically, to an architectural masonry wall binding device that improves the binding force between a masonry wall and an interior wall.

In general, masonry walls are made by stacking bricks in a certain pattern and are joined together using mortar. Bricks for masonry wall construction are convenient to transport to the work site and are easy to handle, so they are widely applied to the construction of internal walls that do not bear load after frame construction. It also has the advantage of being able to simply bury various pipes because the work of digging or drilling grooves on the surface of a masonry wall is simpler than that of reinforced concrete.

When such a masonry wall is installed with an insulating material between it and the inner wall, it is difficult to join the masonry bricks and the inner wall with mortar, so a binding device is used to connect the masonry wall and the inner wall.

An example of such a conventional masonry wall binding device is shown in Figures 1 and 2. Referring to this, the wire insertion plate (1), which has a concavo-convex cross-sectional shape having grooves (1a), (1b) (1c) and protrusions (2), is formed to be continuous in the longitudinal direction, is placed on the brick (3). In this state, the end of the steel wire hook (4) rolled into a loop is spread and hung by inserting it into the locking plate (7) of the bracket (6) fixed to the inner wall (5).

Afterwards, the end of the steel wire ring (4) is inserted into the grooves (1a) and (1b) formed in the wire fitting plate (1), and the straight wire (8) is inserted into the other groove (1c) formed in the wire fitting plate (1). After inserting in the horizontal direction, mortar is covered with a uniform thickness on the brick (3) to bury part of the wire (8), wire insertion plate (1), and steel wire ring (4).

However, this prior art is configured to loosely fit the steel wire ring (4) and the wire (8) into the grooves (1a) (1b) (1c) formed in the wire fitting plate (1), so during masonry work, the steel wire ring ( There is a problem that 4) and the wire (8) are often separated from the grooves (1a) (1b) (1c), so there is an inconvenience that requires careful construction.

In particular, when the brick (3) is covered with mortar, the joint portion of the steel wire ring (4) and the wire (8) inserted into the grooves (1a) (1b) (1c) of the wire insertion plate (1) is buried in the mortar and is not visible. Therefore, it is difficult to check the detached part, and if it is constructed in a detached state, there is a problem that leads to poor construction.

In addition, when hanging the steel wire hook (4) on the bracket (6), the ends of each steel wire hook (4) must be widened and hung, which makes the work cumbersome and delays the work time. When an external force is applied to the wire insertion plate (1) before the mortar hardens and the wire insertion plate (1) slides in a direction closer to the inner wall (5), the connection between the steel wire ring (4) and the bracket (6) becomes loose. There is a problem with loss of support.

In other words, since the prior art is designed to obtain bonding force through hardened mortar, there is a problem in that it does not have any bonding force until the mortar hardens.

The present invention includes a steel wire embedded groove (21) formed at a certain depth on the upper surface of the brick (20); It includes an open groove 22 formed toward the edge of the brick 20 at the rear of the steel wire buried groove 21.

For example, the steel wire embedding groove 21 may be formed in a rectangular shape around the brick hole 23 formed in the center of the upper surface of the brick 20, as shown in FIG. 4. The steel wire buried groove 21 can be formed to have a certain depth and width.

The steel wire embedding groove 21 is formed to have a width larger than the diameter of the steel wire ring 40 below, so that a binder such as mortar can smoothly penetrate into the steel wire embedding groove 21.

For example, the open groove 22 can be formed to have the same depth as the steel wire buried groove 21. The open groove 22 is open toward the rear of the brick 20 and can be formed to have a constant width.

The present invention includes a wall fixing plate (30) installed on the inner wall (10); A lower plate (31) extending horizontally from the bottom of the wall fixing plate (30) toward the brick (20); A steel wire holder (32) formed in an inverted U shape at the front end of the lower plate (31); The upper bent portion of the steel wire holder 32 includes a pair of steel wire insertion grooves 33 formed in parallel at regular intervals.

The wall fixing plate 30, the lower plate 31, and the steel wire holder 32 can all be formed as a single piece using a metal plate with a certain thickness. Nail holes 30h for installing the wall fixing plate 30 on the inner wall 10 can be drilled into the wall fixing plate 30 using concrete nails 11.

The width of the steel wire insertion groove (33) corresponds to the diameter of the tension wire (41). The spacing between the steel wire insertion grooves 33 is formed at the same spacing as the spacing between the tension wires 41 composed of a pair.

The present invention includes a rectangular through hole 34 formed with a certain width in the lower plate 31 and the wall fixing plate 30; A pair of semicircular grooves (35) formed on the left and right edges of the through hole (34); It extends downward from the front end of the through hole 34 and includes a steel wire engaging piece 36 whose lower end is located directly below the semicircular groove 35.

As shown in Figures 5 and 7, the through hole 34 is cut downward after cutting a part of the wall fixing plate 30 and the lower plate 31 in a U-shape to form the steel wire stopping piece 36. This is a perforated hole that remains when bending the portion to form the steel wire locking piece (36).

The inner diameter of the semicircular groove (35) corresponds to the diameter of the hook (42). As shown in FIGS. 7 and 9, the steel wire stopping piece 36 can be formed in an inclined shape that gets closer to the inner wall 10 as it goes downward.

When the hook 42 passes through the locking hole 39 and the semicircular groove 35, the steel wire locking piece 36 contacts the bottom of the hook 42 and is elastically deformed, and the rear end of the hook 42 is the steel wire locking piece. When the lower end of the steel wire latching piece 36 is reached, the steel wire latching piece 36 is restored to its original shape by elastic restoring force, and the hook 42 is caught on the lower end of the steel wire latching piece 36.

The present invention includes a steel wire ring (40) in the form of an open loop that is inserted and embedded in a steel wire embedding groove (21); A pair of tension wires (41) extending in parallel from the rear end of the steel wire ring (40) toward the inner wall (10), passing through the opening groove (22) and inserted into the steel wire insertion groove (33); It extends vertically downward from the rear end of the tension wire 41 and includes a U-shaped hook 42 that passes through the semicircular groove 35 and is caught on the steel wire catching piece 36.

The steel wire ring 40, tension wire 41, and hook can be integrally formed from a steel wire having a certain diameter as shown in FIGS. 4 and 8. As shown in Figure 4, the steel wire ring 40 can be formed in a rectangular shape, and the tension wire 41 can be formed in parallel.

The hook 42 can be formed at the same interval as the tension wire 41, and can be formed by bending at a right angle downward.

The present invention includes a latch bar (50) inserted into the space formed between the inner ceiling of the steel wire holder (32) and the tension wire (41) to prevent the tension wire (41) from being separated; It includes a wire catcher 51 formed in a C-shaped arc at one end of the latch bar 50 to surround a portion of the circumference of the tension wire 41.

The latch bar 50, wire catcher 51, steel wire guide 52, and handle 53 are made of spring steel with a certain width and thickness and can be formed into one piece by bending.

The latch bar 50 corresponds to the inner width of the steel wire holder 32. The wire catcher 51 is formed in a C shape as shown in Figure 10, so that when the tension wire 41 enters the wire catcher 51, the entrance opens, and the tension wire 41 enters the wire catcher 51. When it enters the inside and the center is aligned, the wire catcher 51 is restored to its original shape by elastic restoring force. At this time, separation of the latch bar 50 can be prevented by the wire catcher 51 in close contact with the outer peripheral surface of the tension wire 41.

The present invention includes a steel wire guide portion 52 that is formed to be inclined downward at the end of the wire catcher 51, meets the tension wire 41, and slides to open the entrance of the wire catcher 51; It includes an L-shaped handle 53 formed at the end of the steel wire guide portion 52.

As shown in FIG. 10, the steel wire guide portion 52 may be formed in an inclined shape that moves away from the tension wire 41 as it goes downward. When assembling the wire catcher 51 to the tension wire 41, the entrance of the wire catcher 51 is opened by the steel wire guide portion 52.

The handle 53 can be formed, for example, by extending horizontally in the reverse direction from the bottom of the steel wire guide 52 and then bending the end portion upward.

The present invention includes a pair of side plates (37) formed vertically toward the upper side from the left and right edges of the lower plate (31); A pair of upper plates 38 that extend horizontally from the top of the side plate 37 in opposite directions and meet each other, and are spaced at regular intervals in the vertical direction from the lower plate 31; It is formed to cross the boundary line of the upper plate 38, and includes a locking hole 39 whose both ends overlap the semicircular groove 35 in the vertical direction.

As shown in FIGS. 6 and 7, the side plate 37 is made by folding the metal plate that was integral with the lower plate 31 upward and then folding the upper part of the side plate 37 horizontally in the direction facing each other at a certain height to form the upper plate ( 38) can be molded.

As shown in FIG. 6, the locking hole 39 can be formed by forming a U-shaped groove drilled on the edge of the upper plate 38 to form a slot when both upper plates 38 meet.

As shown in FIG. 8 of the accompanying drawing, forming a spot welding portion 38b at the border of the upper plates 38 can prevent the gap between the upper plates 38 from widening.

Hereinafter, the operation according to the present invention will be described in detail based on the attached drawings.

Install the wall fixing plate (30) on the inner wall (10) using concrete nails (11). When the steel wire ring 40 is inserted into the steel wire embedding groove 21 formed in the brick 20 and the hook 42 is inserted into the semicircular groove 35 through the hanging hole 39, the tension wire 41 is connected to the steel wire. It is inserted into the steel wire insertion groove 33 formed in the holder 32.

At this time, when the lower end of the hook 42, which has passed through the locking hole 39 and the semicircular groove 35, meets the steel wire locking piece 36, the steel wire locking piece 36 is elastically deformed and the hook 42 continues to descend. When the hook 42 is located at the lower end of the steel wire latching piece 36, the steel wire latching piece 36 is restored to its original shape by elastic restoring force, and the hook 42 is caught at the lower end of the steel wire latching piece 36.

When the tension wire 41 is caught at the bottom of the steel wire insertion groove 33, the hook 42 is caught at the bottom of the steel wire catching piece 36, so the vertical movement of the tension wire 41 and the hook 42 is stopped. . At this time, if you hold the handle (53) integrated with the latch bar (50) with your hand and insert the latch bar (50) into the space formed by the inside of the steel wire holder (32) and the tension wire (41), the tension wire (41) It is possible to prevent separation from the steel wire holder (32).

If the handle 53 is pushed harder when the steel wire guide 52 is in contact with the tension wire 41, the steel wire guide 52 slides on the tension wire 41. At this time, the entrance of the wire catcher (51) opens and the tension wire (41) enters the inside of the wire catcher (51).

When the tension wire 41 enters the inside of the wire catcher 51, the wire catcher 51 recovers its original shape by elastic restoring force and the wire catcher 51 comes into close contact with the outer peripheral surface of the tension wire 41. The latch bar 50 can be prevented from being separated from the steel wire holder 32 by the wire catcher 51 biting the outer peripheral surface of the tension wire 41.

On the other hand, when an earthquake occurs and a force acts in the left and right horizontal directions in the longitudinal direction of the brick 20, a pair of tension wires 41 are inserted into the steel wire insertion groove 33, and the steel wire holder 32 is Since it is formed in an inverted U-shaped double wall structure, the left and right horizontal bending and movement of the tension wire 41 can be greatly reduced.

When an earthquake occurs and force is applied in the direction of the thickness of the masonry wall, tensile force is applied to the tension wire 41 through the steel wire ring 40 connected to the brick 20. At this time, the hook 42 is firmly hung on the locking hole 39 formed in the upper plate 38 and the semicircular groove 35 formed in the lower plate 31, so that the masonry wall can be prevented from being easily separated from the inner wall 10.

When an earthquake occurs and the masonry wall vibrates in the vertical direction, force acts in the vertical direction on the tension wire 41 through the steel wire ring 40 connected to the brick 20. At this time, the tension wire 41 is hung at the bottom of the steel wire insertion groove 33, so it resists the force acting in the downward direction, and the hook 42 is hung at the bottom of the steel wire holding piece 36, so it resists the force acting in the upward direction. resist.
