Description

[Technical Field]

[0001] The present invention relates to a support structure for exterior materials that reinforces exterior materials to prevent them from cracking and prevents them from scattering even if they do crack. [Background technology]

[0002] There are two methods for attaching exterior materials such as tiles to the exterior walls of buildings: the wet method, which uses water, and the dry method, which does not use water. The wet method is a method in which the exterior material is attached directly to the base material with mortar, while the dry method is a method in which the exterior material is attached indirectly with an elastic adhesive to supporting metal fittings fixed to the base material.

[0003] In dry tiling methods, a gap is created between the back of the tile and the base material, so if the tile receives an external impact, it may break, and pieces of the broken tile may fly around.

[0004] Therefore, as a measure to prevent shattering, butyl tape or the like is attached to the entire back of the tiles, or fiberglass mesh is applied with adhesive to prevent pieces from falling off even if the tiles break.

[0005] As described in Patent Document 1, an invention is also disclosed that relates to a suitable anti-scattering construction method that prevents the scattered or falling of crushed blocks or tiles, even if the blocks or tiles for the exterior walls of buildings such as offices or apartment buildings or detached houses are crushed. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-023870 Summary of the Invention [Problem to be solved by the invention]

[0007] The invention described in Patent Document 1 involves coating the backside of a ceramic block or tile with moisture-permeable and waterproof properties with a primer, and then heating, laminating, and fixing a reinforcing sheet made of a spunbonded long synthetic fiber nonwoven fabric laminated with a thermally adhesive nonwoven fabric via the thermally adhesive nonwoven fabric side.While this is effective in preventing broken tiles from flying apart, it does not mitigate impact on the tiles, increase their strength, or prevent them from cracking.

[0008] Furthermore, when a building shakes due to an earthquake or other event, distortion can occur, potentially causing the exterior material to crack. Therefore, support brackets are sometimes attached to the center of the base material to allow them to rotate, allowing them to adapt to shaking. However, as the exterior material becomes larger, the edges of the support brackets are more likely to peel off due to wind pressure, etc., so if the ends of the support brackets are fixed to the base material, they will no longer be able to absorb distortion caused by vibrations.

[0009] Therefore, the present invention aims to provide an exterior material support structure that reinforces exterior materials to prevent them from cracking and prevents them from scattering even if they do crack. Another aim is to ensure the earthquake resistance and wind pressure resistance of buildings. [Means for solving the problem]

[0010] In order to solve the above problems, the exterior material support structure of the present invention comprises a base material that is fixed to the exterior wall of a building, a horizontal support bracket that spans the front of the base material from the left end to the right end, an exterior material that is supported by the support bracket and has its back surface bonded to the base material with an elastic adhesive that is entangled with the support bracket, a reinforcing board that is bonded to the back surface of the exterior material above or below the support bracket, and a board holding bracket for engaging the reinforcing board to the support bracket, wherein one end of the board holding bracket is bent into a crank shape and is sandwiched between the base material and the support bracket, and the other end is inserted elastically between the exterior material and the reinforcing board.

[0011] Furthermore, in the exterior material support structure, the board holding fitting is characterized in that one end thereof is bent upward and downward into a crank shape and sandwiched between the exterior material and the reinforcing board, and the other end thereof is inserted elastically between the base material and the support fitting.

[0012] The exterior material support structure also comprises a base material fixed to the exterior wall of the building, a horizontal support bracket that spans the front of the base material from the left end to the right end, an exterior material that is supported by the support bracket and has its back surface bonded to the base material with elastic adhesive entangled with the support bracket, and a reinforcing board that is bonded to the back surface of the exterior material above or below the support bracket, and the support bracket has its tip bent so that its top and bottom are raised above the base material and is sandwiched between the exterior material and the reinforcing board.

[0013] The exterior material support structure also comprises a base material fixed to the exterior wall of the building, a horizontal support bracket spanning the front of the base material from the left end to the right end, an exterior material supported by the support bracket and having its back surface bonded to the base material with an elastic adhesive entangled in the support bracket, a reinforcing board bonded to the back surface of the exterior material above or below the support bracket, and a board holding bracket whose tip is bent into a hook shape and is inserted elastically between the exterior material and the reinforcing board, and the board holding bracket is equipped with an adjustment plate that presses like a spring from the reinforcing board against the base material to even out any unevenness in the base material.

[0014] The exterior material support structure also comprises a base material fixed to the exterior wall of the building, a horizontally long support bracket placed on the front of the base material, an exterior material supported by the support bracket and having its back surface bonded to the base material with an elastic adhesive entangled in the support bracket, a reinforcing board bonded to the back surface of the exterior material above or below the support bracket, and a board holding bracket whose one end is bent so that the top and bottom are raised from the base material and whose end is sandwiched between the exterior material and the reinforcing board, and whose other end presses against the left end of the support bracket and the right end of the adjacent support bracket from the front so that the top or bottom is cushioned.

[0015] The external material support structure is also characterized in that a gap is provided between the board holding fitting and the underside of the reinforcing board, with a buffer material interposed therebetween.

[0016] In addition, the external material support structure is characterized in that the support fitting has a bridge formed thereon to ensure a gap so that the elastic adhesive can be entangled.

[0017] In addition, in the external material support structure, the support fitting is characterized in that it is provided with a claw on which the external material can be placed when bent and erected. [Effects of the Invention]

[0018] According to the present invention, by increasing the strength of the exterior material using a reinforcing plate, the exterior material can be reinforced to prevent cracking, and even if the exterior material does crack, the fragments can be prevented from scattering.

[0019] In addition, even with large exterior materials, the edges of the support fittings will not peel off due to wind pressure or other factors, causing flapping noises, and even when large vibrations such as earthquakes occur, distortion in the base material and support fittings that secure the exterior materials is suppressed, allowing the exterior materials to follow the shaking.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Components having the same function will be assigned the same reference numerals, and repeated explanations may be omitted. The outside of a building will be referred to as the front, and the inside as the back. [Example]

[0022] Fig. 1 shows (a) a front view, (b) a plan view, and (c) a cross-sectional side view of an exterior wall using the exterior material support structure of the present invention, with tiles visible through the view. Fig. 2 shows (a) a front view, (b) a plan view, and (c) a side view of an enlarged portion of an exterior wall using the exterior material support structure. Fig. 3 shows (a) a perspective view of a support bracket used in an exterior wall using the exterior material support structure, and (b) an exploded view of the side of the exterior wall. Fig. 4 shows (a) a front view, (b) a plan view, (c) a side view, and (d) a perspective view of a board holding bracket used in an exterior wall using the exterior material support structure.

[0023] As shown in Figure 1, the exterior material support structure comprises a base material 210 fixed to the exterior wall 100 of a building, a horizontally long support bracket 300 that runs across the front of the base material 210 from the left end to the right end, an exterior material 200 that is supported by the support bracket 300 and has its back surface bonded to the base material 210 with elastic adhesive 220 entangled in the support bracket 300, a reinforcing board 230 that is bonded to the back surface of the exterior material 200 above or below the support bracket 300, and a board holding bracket 400 for engaging the reinforcing board 230 to the support bracket 300.

[0024] As shown in Figure 2, the base material 210 is attached to the front of a plurality of pillar materials 110, such as pillars or partitions arranged at intervals, by sandwiching a plurality of furring strips 130 between two structural plywood panels 120 to ensure a space. The structural plywood panels 120 are wall materials used to create load-bearing walls, and improve earthquake resistance, wind resistance, airtightness, soundproofing, and other properties. The furring strips 130 are wall materials used to improve breathability and strength, and may be provided at the positions of the pillar materials 110. Screws 140 are driven through the base material 210 to the pillar materials 110.

[0025] 3(a), the support bracket 300 is a bracket extending laterally for supporting the exterior packaging material 200, and is arranged intermittently above and below, and is used to place the upper exterior packaging material 200 on top or hang the lower exterior packaging material 200a. When multiple base materials 210 are arranged side by side, the support bracket 300 may be attached so as to straddle adjacent base materials 210.

[0026] The support bracket 300 has a contact plate 310 that contacts the base material 210, an upper end plate 320 formed by bending the upper part of the contact plate 310 forward, and a lower end plate 320a formed by bending the lower part of the contact plate 310 forward. The upper end plate 320 and the lower end plate 320a ensure a space between the base material 210 and the exterior material 200.

[0027] Bridges 340 are formed on the support bracket 300 to ensure a gap so that the elastic adhesive 220 can be entangled. For example, when providing bridges 340 at the top and bridges 340a at the bottom of the support bracket 300, gaps can be created by making cuts at the top and bottom and pushing them forward.

[0028] The support fitting 300 is provided with claws 330 on which the exterior packaging material 200 can be placed when folded and erected. For example, concave cuts (on the left, right, and bottom) can be made in the support fitting 300, and the support fitting 300 can be rotated upward and erected to a horizontal position. The claws 330 may be provided with ribs for reinforcement.

[0029] When the support bracket 300 is placed between the upper exterior material 200 and the lower exterior material 200a, the claws 330 are placed in an upright position, and when the support bracket 300 is placed on the back side of the exterior material 200, the claws 330 are placed in a reclined position.

[0030] Additionally, a processed portion 350 is formed in the support bracket 300. The support bracket 300 is placed against the base material 210 and fastened with screws 140, and elongated holes 350 or round holes 350a are drilled in the support bracket 300 so that it can be aligned with the positions of the pillar material 110 and furring strips 130. Also, embossed protrusions 350b may be provided to reinforce the spaces between the claws 300.

[0031] The exterior material 200 is a tile or the like that decorates the exterior wall 100 and protects it from wind, rain, fire, etc. It is placed on, hooked onto, or fastened to a support bracket 300, and then adhered to the base material 210 using an elastic adhesive 220. The elastic adhesive 220 hardens into a rubber-like material that has adhesive strength and flexibility, and is silicone-based or the like.

[0032] As shown in FIG. 3(b), the reinforcing board 230 is a plate material that is attached to the rear surface of the exterior packaging material 200 with adhesive 240 to reinforce the exterior packaging material 200, and may be a shell board (magnesium plate) containing magnesium.

[0033] In the case of the dry construction method, there is a gap between the back surface of the exterior material 200 and the base material 210, so the exterior material 200 is prone to cracking due to external impact. By attaching butyl tape or fiberglass mesh to the entire back surface of the exterior material 200, it is possible to prevent fragments from scattering even if the exterior material 200 is hit by a flying object such as a stone and cracks after it has been finished as the exterior wall 100.

[0034] The exterior material 200 is not prevented from cracking itself, and it is difficult to protect it from cracking during transportation before construction, especially when the size of the exterior material 200 is large. However, by attaching the reinforcing board 230 to the exterior material 200 so as to fill the gap between the exterior material 200 and the base material 210, both cracking of the exterior material 200 and scattering of fragments can be prevented.

[0035] Since a support bracket 300 is also present on the back side of the exterior material 200, a reinforcing board 230 can be attached to the back side of the upper exterior material 200 above the support bracket 300, and a reinforcing board 230a can be attached to the back side of the lower exterior material 200a below the support bracket 300.

[0036] The exterior material 200 and the reinforcing board 230 are bonded with adhesive 240, and the exterior material 200 and the base material 210 are bonded with elastic adhesive 220 that can absorb vibrations, but the reinforcing board 230 is not bonded to the base material 210. When vibrations such as earthquakes occur, the exterior material 200 and the base material 210 are not locked and can move independently, which improves earthquake resistance.

[0037] As shown in Figure 4, the board holding bracket 400 has an upper vertical plate 410, a middle horizontal plate 420 bent horizontally from the upper vertical plate, a lower vertical plate 430 bent vertically from the middle horizontal plate, and a spring-shaped retainer 440 made by slightly bending the upper end of the upper vertical plate 410.

[0038] The board holding fitting 400 is a fitting for inserting the reinforcing board 230 in a kendon style and holding the reinforcing board 230. The board holding fitting 400 has a crank-shaped bent end, the lower vertical plate 430, which is sandwiched between the base material 210 and the support fitting 300, and the other end, the upper vertical plate 410, which is inserted elastically between the exterior material 200 and the reinforcing board 230.

[0039] By fixing the support bracket 300 with the screws 140, the board holding bracket 400 with the lower vertical plate 430 sandwiched therebetween is also fastened, and the reinforcing board 230 can be inserted between the upper vertical plate 410 and the base material 210.

[0040] Both the upper board-holding metal fitting 400 and the lower board-holding metal fitting 400a have a space between them and the reinforcing boards 230, 230a, but a buffer material 250 is interposed between them and the underside of the upper reinforcing board 230. This makes it possible to absorb shock even if the metal fitting moves due to vibration. Note that a buffer material 250 may also be interposed between them and the top surface of the lower reinforcing board 230a. [Example]

[0041] Fig. 5 shows an enlarged view of a portion of an exterior wall using the exterior material support structure of the present invention, with (a) a front view with tiles visible through it, (b) a plan view, and (c) a side cross-sectional view. Fig. 6 shows (a) a front view with the claws raised, (b) a plan view, (c) a side view, (d) a front view with the claws lowered, (e) a plan view, and (f) a side view of a support bracket used in an exterior wall using the exterior material support structure. Fig. 7 shows (a) a front view, (b) a plan view, (c) a side view, and (d) a perspective view of a board holding bracket used in an exterior wall using the exterior material support structure.

[0042] As shown in Figure 5, in the exterior wall 100a, one end (upper vertical plate 610) of the board holding bracket 600 is bent up and down in a crank shape and sandwiched between the exterior material 200 and the reinforcing board 230, and the other end (lower vertical plate 630) is inserted elastically between the base material 210a and the support bracket 500.

[0043] Various materials can be used for the base material 210a, such as wood, RC (reinforced concrete), ALC (autoclaved lightweight concrete) panel, ECP (extruded cement board), and C-channel (shaped steel).

[0044] As shown in Figure 6, the support bracket 500 has a contact plate 510 that rests against the base material 210a, an upper horizontal plate 520 whose upper side is bent forward, an upper front plate 510a bent further upward, a lower horizontal plate 520a bent forward from the lower side of the contact plate 510, a lower front plate 510b bent downward from that, and a lower end plate 520b bent further backward.

[0045] The support bracket 500 is also formed with processed portions 550, including elongated holes 550 for screws 140, round holes 550a, square holes 550b for reducing weight and for passing and entangling elastic adhesive 220, cutouts 550c, and notches 560. Cutouts 550c are recessed to provide claws 530 that can rotate to a horizontal position. Cutouts 560 make it easier to insert lower board holding bracket 600a.

[0046] As shown in Figure 7, the board holding bracket 600 has an upper vertical plate 610, a middle horizontal plate 620 bent horizontally from the upper vertical plate, a lower vertical plate 630 bent vertically from the middle horizontal plate, and spring-like retainers 640 bent forward on the left and right sides of the lower vertical plate 630.

[0047] From the upper side of the support bracket 500, the board holding bracket 600 is inserted between the upper front plate 510a and the base material 210a, and from the lower side of the support bracket 500, the board holding bracket 600a is inserted between the lower front plate 510b and the base material 210a.

[0048] The board holding fittings 600, 600a are supported by the elasticity of the retainer 640, and the reinforcing boards 230, 230a attached to the backside of the exterior materials 200, 200a are held by the board holding fittings 600, 600a. By interposing a buffer material 250 between the board holding fittings 600 and the reinforcing board 230, movement is absorbed and it is possible to follow vibrations. [Example]

[0049] Fig. 8 shows (a) a front view, (b) a plan view, and (c) a side cross-sectional view of an exterior wall using the exterior material support structure of the present invention, with the tiles visible through the view. Fig. 9 shows (a) a front view, (b) a plan view, and (c) a side view of an enlarged portion of an exterior wall using the exterior material support structure. Fig. 10 shows (a) a front view, (b) a plan view, (c) a side view, and (d) a perspective view of a support bracket used in an exterior wall using the exterior material support structure, with the claws raised. Fig. 11 shows (a) a front view, (b) a plan view, (c) a side view, and (d) a perspective view of a support bracket used in an exterior wall using the exterior material support structure, with the claws lowered.

[0050] As shown in Figure 8, the exterior material support structure includes a base material 210a fixed to the exterior wall 100b of the building, a horizontally long support bracket 700 that runs across the front of the base material 210a from the left end to the right end, an exterior material 200 that is supported by the support bracket 700 and has its back surface bonded to the base material 210a with elastic adhesive 220 entangled in the support bracket 700, and a reinforcing board 230 that is bonded to the back surface of the exterior material 200 above or below the support bracket 700.

[0051] 9, the support fittings 700 are bent so that the top and bottom are raised above the base material 210a, and the ends are sandwiched between the exterior material 200 and the reinforcing board 230. The reinforcing board 230 is held by the support fittings 700 without using any hod holding fittings.

[0052] As shown in Figure 10, the support bracket 700 with its claws 730 raised has a contact plate 710 that rests against the base material 210a, an upper horizontal plate 720 with its upper side bent forward, an upper front plate 710a bent further upward, a lower horizontal plate 720a with the lower side of the contact plate 710 bent forward, and a lower front plate 710b bent downward from that.

[0053] The support bracket 700 also has bridges 740 formed thereon for entangling the elastic adhesive 220. For example, the bridges 740 are formed using square holes 750b formed in the upper part of the support bracket 700, and the bridges 740a are formed using notches 750c and cutouts 750d formed in the lower part of the support bracket 700.

[0054] The processed portion 550 of the support bracket 500 also includes an elongated hole 750 for the screw 140, a round hole 750a, a square hole 750b for passing and entangling the elastic adhesive 220, a notch 750c, and a cutout 750d. The cutout 750d is cut in a concave shape to provide a claw 730 that can rotate to a horizontal position. In order to insert the reinforcing board 230a from below, the lower end of the lower front panel 710b is not bent backward, and the notch 750c is also left open.

[0055] As shown in FIG. 11, the support fitting 700a with the tabs 730 folded down is in a state where the outer packaging material 200a is large, the support fitting 700a is placed on the back side of the outer packaging material 200a, and there is no need to place the outer packaging material 200a on it.

[0056] The reinforcing board 230 is inserted between the upper front plate 710a and the base material 210a of the support bracket 700, and the reinforcing board 230a is inserted between the lower front plate 710b and the base material 210a. A buffer material 250 is interposed between the upper horizontal plate 720 and the lower end of the reinforcing board 230. [Example]

[0057] Figure 12 shows (a) a front view, (b) a plan view, and (c) a cross-sectional side view of an exterior wall using the exterior material support structure of the present invention, with tiles visible through the view. Figure 13 shows (a) a front view, (b) a plan view, (c) a side view, and (d) a perspective view of a board holding bracket used in an exterior wall using the exterior material support structure.

[0058] As shown in Figure 12, the exterior material support structure comprises a base material 210b fixed to the exterior wall 100c of the building, a horizontally long support bracket 300 that runs across the front of the base material 210b from the left end to the right end, an exterior material 200 that is supported by the support bracket 300 and has its back surface bonded to the base material 210b with elastic adhesive 220 entangled in the support bracket 300, a reinforcing board 230 that is bonded to the back surface of the exterior material 200 above or below the support bracket 300, and a board holding bracket 800 whose tip is bent into a hook shape and is inserted elastically between the exterior material 200 and the reinforcing board 230.

[0059] When the base material 210b is RC (reinforced concrete), the surface is often not flat and has irregularities such as bumps and grooves, so the board holding bracket 800 is provided with an adjustment plate 820 that presses against the base material 210b in a spring-like manner from the reinforcing board 230 to smooth out any irregularities in the base material 210b.

[0060] The board holding fitting 800 engaged with the reinforcing board 230 above the support fitting 300a is fixed to the base material 210b with screws 140a, and the board holding fitting 800a engaged with the reinforcing board 230a below the support fitting 300a is fixed with screws 140a. When no exterior material 200 is to be placed on the support fitting 300a, the support fitting 300a is laid down with the claws 330 not raised.

[0061] It is also possible to prevent the exterior packaging material 200 from falling by using a long, pin-shaped fall prevention metal fitting 150. For example, one end of the fall prevention metal fitting 150 may be attached to the base material 210b with adhesive 240a or hooked onto a support metal fitting 300a to fix it, and the other end of the fall prevention metal fitting 150 may be made into a claw shape so that the exterior packaging material 200 can be placed on it or hung by hooking it.

[0062] As shown in Figure 13, the board holding bracket 800a has a front plate 810 that is placed against the back surface of the reinforcing board 230, an adjustment plate 820 whose left and right sides are bent diagonally backward to make it elastic, a locking plate 830 that is hook-shaped to hang the front plate 810 on the reinforcing board 230, a retainer 840 that is made spring-shaped by slightly bending the lower end of the locking plate 830, and a fastening hole 850 that is drilled to fasten it to the base material 210b with a screw 140a.

[0063] Since unevenness is adjusted by the board holding metal fittings 800, 800a, even if the base material 210b has irregularities or is tilted, the adjusting plate 820 comes into contact with the base material 210b in a spring-like manner, and the exterior material 200 is supported without tilting.

[0065] As shown in Figure 14, the exterior material support structure comprises a base material 210 fixed to the exterior wall 100d of the building, a horizontally long support bracket 300 placed on the front of the base material 210, an exterior material 200 supported by the support bracket 300 and having its back surface bonded to the base material 210 with elastic adhesive 220 entangled in the support bracket 300, a reinforcing board 230 bonded to the back surface of the exterior material 200 above or below the support bracket 300, and a board holding bracket 900 whose one end is bent so that the top and bottom are raised above the base material 210 and which is sandwiched between the exterior material 200 and the reinforcing board 230.

[0066] As shown in Figure 15, the other end (lower front plate 910b) of the board holding bracket 900, 900a presses the left end of the support bracket 300 and the adjacent right end of the support bracket 300 from the front so that movement is absorbed by the cushioning material 250, 250a above or below during vibration.

[0067] The board holding bracket 900 is fixed to the base material 210 with screws 140a after cushioning material 250 is placed on the upper side between the two support brackets 300, and the board holding bracket 900a is fixed to the base material 210 with screws 140a after cushioning material 250a is placed on the lower side between the two support brackets 300.

[0068] As shown in Figure 16, the board holding bracket 900 has a contact plate 910 that is placed against the base material 210, an upper horizontal plate 920 whose upper side is bent forward, an upper front plate 910a that is bent further upward, a lower horizontal plate 920a that is bent forward from the lower side of the contact plate 910, and a lower front plate 910b that is bent downward from that.

[0069] The processed portion 930 of the board holding bracket 900 includes a long hole 930 and a round hole 930a for the screw 140. A buffer material 250 is placed below the lower horizontal plate 920a to absorb distortion caused by movement of the support bracket 300.

[0070] As shown in Figure 17, the board holding bracket 900a has the same shape as the board holding bracket 900, but turned upside down, and a buffer material 250a is placed on the upper side of the upper horizontal plate 920 to absorb distortion caused by movement of the support bracket 300.

[0071] 18, in response to building movement due to vibrations such as an earthquake, each support bracket 300 attempts to rotate around the screw 140 fastened to the base material 210, causing significant distortion at the ends of the support brackets 300. Even if two adjacent support brackets 300 move differently, a space is provided between the board holding brackets 900, 900a that hold them in place to ensure a range of movement, and the buffer material 250 absorbs the distortion that accompanies this movement.

[0072] If the exterior material 200 is large, the ends of the support bracket 300 are also susceptible to the effects of wind pressure, etc., but peeling or curling up due to not fixing the ends with screws 140 to ensure the movement of the support bracket 300 can be avoided by pressing down from the front with the lower front plate 910b of the board holding bracket 900, 900a.

[0073] According to the present invention, by increasing the strength of the exterior material using a reinforcing plate, the exterior material can be reinforced to prevent cracking, and even if the exterior material does crack, fragments can be prevented from scattering.

[0074] Furthermore, even with large exterior materials, the edges of the support fittings will not peel off due to wind pressure or other factors, causing flapping noises, and even in the event of large vibrations such as an earthquake, distortion in the base material and support fittings that secure the exterior material is suppressed, allowing the exterior material to follow the shaking.

[0075] Although the embodiments of the present invention have been described above, the present invention is not limited to these. [Explanation of symbols]
