The bricks 200 are stacked alternately so that the bricks 200 adjacent to the left and right are arranged intermittently in each stage so that the sides overlap each other.

The brick 200 is a building material in which clay or the like is placed in a mold and baked in a kiln, and is mainly used for stacking rectangular parallelepiped shapes to form an outer wall. Nowadays, it is sometimes attached as a finishing material like tiles to the surface of the outer wall of wooden or reinforced concrete structures. In addition, antique bricks obtained when an old building is demolished may be reused as sliced bricks cut into plates.

The brick 200 has a horizontally long rectangular parallelepiped shape, and is placed on a support metal fitting fixed to a base material 110 of the outer wall 100. The support metal fitting is a set of a vertically long dowel metal fitting 400 and an auxiliary plate 500, and a plurality of the support metal fittings are arranged at predetermined intervals in the horizontal direction, and a plurality of bricks 200 can be placed vertically.

Of the bricks 200, in the first-stage brick 200a, the first left end side is placed on the first support metal fitting, the right end side is placed on the second support metal fitting, and the second left end side is placed on the third support metal fitting. The right end side is placed on the fourth support metal fitting, and a space is provided between the first and the second. The first left end side of the second stage brick 200b is placed on the second support metal fitting, and the right end side is placed on the third support metal fitting, and the first stage brick 200a is laterally displaced by half. If the third stage is the same as the first stage, the stages are staggered.

The right end side of the brick 200a of the first stage and the left end side of the brick 200b of the second stage are placed on the second support metal fitting, and a part overlapping the brick 200a and the brick 200b is generated. Connect to.

As shown in FIGS. The lower dowel hole 220b is opened. The dowel holes 210b and 220b on the right end side of the brick 200a in the first stage and the dowel holes 210a and 220a on the left end side of the brick 200b in the second stage are vacated in a straight line.

The upper dowel hole 210 is drilled deep to the vicinity of the center of the brick 200, and the lower dowel hole 220 is drilled shallower than the upper dowel hole 210. The dowel pin 600 is inserted from the upper dowel hole 210 of the brick 200b to the lower dowel hole 220 of the brick 200a above it. The upper dowel hole 210 is not penetrated through the lower dowel hole 220 so that the dowel pin 600 does not come off.

The support metal fitting is fixed to the base material 110 by the fastener 120. The fastener 120 may be formed by embedding a plug in the base material 110 and screwing a screw or the like into the plug. Further, the brick 200 placed on the support metal fitting is attached to the base material 110 with an adhesive 130 such as an elastic system.

A joint material 300 is filled between the second-stage brick 200b and the first-stage brick 200a above the second-stage brick 200b so as to surround the dowel pin 600. As shown in FIG. 3, mortar or the like may be used for wet construction, or as shown in FIG. 4, chloroprene rubber or the like may be used for dry construction.

FIG. 6 is a plan view (a) plan view (b) front view (c) right side view showing a metal fitting for a dowel used in a method for constructing an openwork brick wall material. FIG. 7 is a plan view (a) plan view (b) front view (c) right side view showing an auxiliary plate used in a method for constructing an openwork brick wall material.

As shown in FIG. 5, the support metal fittings are formed by arranging auxiliary plates 500 on the rear side of the dowel metal fittings 400 and stacking them in the front-rear direction. The auxiliary plate 500 may be formed so as to overlap the front side of the dowel metal fitting 400, or the support metal fitting in which the dowel metal fitting 400 and the auxiliary plate 500 are integrally molded may be used.

The support metal fitting has an empty space 440 for adhering the brick 200 and the base material 110 by cutting out a mounting plate 430 for mounting the brick 200 from the back plate 410 of the dowel metal fitting 400 that comes into contact with the base material 110. The adhesive 130 is entwined by forming a bridge 530 with the auxiliary plate 500 so as to float from the base material 110 in the empty space 440.

When the dowel metal fitting 400 and the auxiliary plate 500 are overlapped, the bridge 530 of the auxiliary plate 500 is passed through the empty space 440 of the dowel metal fitting 400 and protrudes to the front side of the dowel metal fitting 400. By passing the bridge 530 through the adhesive 130 between the brick 200 and the base material 110, peeling of the adhesive 130 is suppressed.

Further, the retaining hole 460 of the dowel metal fitting 400 and the through hole 540 of the auxiliary plate 500 are holes for passing the fastener 120 for fixing the support metal fitting to the base material 110, and can be pulled out to the base material 110. All you have to do is align them.

As shown in FIG. 6, the dowel metal fitting 400 secures a space between the brick 200 and the base material 110 by providing the side plates 420 in which the left and right ends of the vertically long back plate 410 are bent forward and erected. At the same time, a space for accommodating the head of the fastener 120 for fixing the support metal fitting to the base material 110 is secured.

By cutting out the back plate 410 of the dowel metal fitting 400 in an inverted U shape and making a pin hole 450 in the mounting plate 430 protruding horizontally to the front side, when the brick 200a is placed on the mounting plate 430, the lower part is The dowel pins 600 protruding upward from the side bricks 200b are penetrated, and the bricks 200 can be connected up and down.

The empty space 440 formed by cutting out the mounting plate 430 serves as a gap for passing the adhesive 130 from the base material 110 to the brick 200 at the place where the support metal fittings are arranged. It also serves as a gap for passing the bridge 530 of the auxiliary plate 500.

As shown in FIG. 7, the auxiliary plate 500 is provided with a bridge 530 and a gap 520 at a position overlapping the empty portion 440 of the dowel fitting 400 with respect to the vertically long rear plate 510. When the gap 520 is opened, the bridge 530 may be formed by intermittently leaving a plurality of (for example, two) vertical line-shaped portions and pressing them so as to push them up to the front side.

FIG. 10 is a diagram illustrating a situation in which bricks are exchanged in an outer wall constructed by a method of constructing an openwork brick wall material.

As shown in FIGS. 8 and 9, in the dowel pin 600, a spring material 620 that can be contracted to a length equal to or longer than the length of the lower dowel hole 220 is attached under the shaft body 610. As the spring material 620, a coil spring or the like having the same diameter as the shaft body 610 of the dowel pin 600 is used.

When constructing a new outer wall 100, the bricks 200 may be stacked in order from the bottom. The brick 200 may be placed on the mounting plate 430 of the dowel metal fitting 400, and the dowel pin 600 may be passed through the pin hole 450 and the upper dowel hole 210 so that the brick 200 can be inserted into the lower dowel hole 220 of the brick 200 to be placed on the upper side.

As shown in FIG. 10, when replacing the brick 200a in the middle of the existing outer wall 100, the dowel pin 600b is pushed into the upper dowel hole 210 of the lower brick 200b already placed, and the dowel metal fitting 400 is used. The mounting plate 430 is used to maintain the contraction of the spring material 620 of the dowel pin 600b. The pin hole 450 of the mounting plate 430 may be opened / closed, or a shutter such as a plate material may be interposed to close the pin hole 450.

The dowel pin 600a is inserted into the upper dowel hole 210 of the brick 200a to be replaced, and the brick 200a is fitted while maintaining the contraction of the spring material 620 of the dowel pin 600a by using the upper brick 200c already placed.

When the brick 200a is fitted, the dowel pin 600a is released from the contraction of the spring material 620 and enters the lower dowel hole 220 of the upper brick 200c. Further, by opening the pin hole 450 of the mounting plate 430 on which the brick 200a is placed, the contraction of the spring material 620 of the dowel pin 600b is released, and the brick 200a enters the lower dowel hole 220 of the brick 200a.

According to the present invention, even if the stacked bricks are partially damaged, only the damaged bricks can be replaced without reassembling the entire bricks. Only the brick to be replaced can be removed by destroying it, and a new brick can be fitted while being supported from above and below.

Examples of the present invention have been described above, but the present invention is not limited thereto. For example, it can be applied not only to openwork brickwork but also to other brickwork. Further, it can be applied not only to bricks but also to wall materials such as tiles, resins, woods and stones.
