Description

  TECHNICAL FIELD The present invention relates to a wall structure comprising a wall tile for constructing an outer wall, a mounting bracket thereof, and a combination thereof, and a hook-type mounting in which the tile is provided on a wall base as a result of joining the tiles. The present invention relates to a configuration for hooking and mounting on a metal fitting.

  The present applicant has already disclosed a tile having a joint structure and a mounting structure thereof (Patent Documents 1 and 2). In addition to this, tiles having a consensus joint structure have been known (Patent Documents 3 to 6).

  That is, the structure is such that, out of the four sides of the tile, one of the two sides is formed with a solid (underlap) projecting from the back side edge of the tile, and the other two sides are projected to the front side of the tile. A solid (overlapping part) is formed.

  According to the tile having such a joint structure, since the back and surface of adjacent tiles overlap each other, the waterproofness of the vertical joint and the horizontal joint is excellent.

  By the way, there are a wet method using an adhesive and a dry method in which the tile is fixed without using an adhesive. Among these, when it is wet, it takes time for the adhesive to dry, and it is difficult to shorten the construction period.

  On the other hand, in the dry method, there is a method of nailing tiles on the horizontal trunk edge of the wall base, but it is troublesome to nail one by one, and the tile may break when nailing .

  As another dry fixing method, there is also a method of attaching a rail-shaped hook-type mounting bracket to the trunk column and hooking a tile on this mounting bracket. However, conventionally, since the concave portion for hooking the hook is provided on the back surface of the tile, the thickness of the tile at that portion is reduced, and the strength of the tile is reduced. In addition, the hooks of the metal fittings are often formed obliquely upward, and the concave portions of the tiles must be inclined at a corresponding angle, but in the press working which is a general molding method of tiles, In order to form such an inclined recess, a special mold and a mold release method are required.

  The present invention has been made in order to solve the above-mentioned problems. The object of the present invention is to provide a wall tile and its mounting bracket that are easy to mold and have excellent workability, and thus have good workability. It is to disclose a wall structure that can be constructed.

  In order to achieve the above-described object, in the present invention, a rectangular substrate portion having a tile thickness, an overlap portion that continues to the lower edge of the substrate portion through a back surface side step portion having a thickness of approximately half, A continuous underlap portion is formed integrally on the upper edge of the substrate portion via a surface side step portion having a thickness of approximately half, and a corner angle between the overlap portion and the back side step portion is formed below the tile. In addition, a slit that is cut perpendicularly to the substrate portion side and opened at the lower end and both left and right ends is provided, and the slit can be hooked from above by hooking on a hook-type mounting bracket provided on the wall base.

  The substrate portion is a base of the tile, and as a result, an underlap portion is provided on the upper edge and an overlap portion is provided on the lower edge. The underlap portion and the overlap portion can be provided upside down. However, in the case where a mounting bracket described later is applied, the upper edge is the underlap portion and the lower edge is the overlap portion.

  The slit on the lower side of the tile is a portion that hooks on the hook-type mounting bracket, and the cutting direction is vertical.By inserting the hook of the mounting bracket from the lower end opening of the slit, the tile is placed in a vertical posture. Can be fixed. Since the insertion of the hook into the slit is maintained by the weight of the tile, if the tile is lifted vertically, the hook is released, the tile can be removed from the mounting bracket, and remodeling and disassembly is easy. Furthermore, if the slit is provided over the entire length of the even angle and both left and right ends are opened, the tile can be slid left and right in this state after being hooked on the mounting bracket, and the position can be adjusted.

  In the present invention, it is essential to provide a hook latching slit on the lower side of the tile, but also on the upper side of the tile, an even angle between the underlap part and the surface side step part is cut vertically to the substrate part side. It is preferable to provide separate slits that are open at the top and left and right ends. This is because when the mounting bracket described later is applied, the upper slit functions as an escape portion when the upper edge underlap portion is inserted into the mounting bracket from below.

  These slits can be formed by, for example, inserting a plate material having the same thickness along the tile plane direction during press processing, extracting the plate material after pressing, and releasing the tile.

  On the other hand, the shape of the substrate portion may be a rectangular shape, and is not limited to a rectangular shape, and may be a parallelogram or a trapezoid. Moreover, although the shape of a surface or a back surface is not ask | required, it is preferable to provide the recess of the depth corresponding to the thickness of the attachment part with respect to the wall foundation | substrate of an attachment metal fitting in the back surface of a board | substrate part. This is because the thickness of the mounting portion of the mounting bracket is absorbed by this recess, and adjacent tiles can be securely fixed to the mounting bracket in a vertical posture without any step.

  In addition, the waterproofness of the horizontal joint is increased by the upper edge and the lower edge of the board part being joined together, but by providing the overlap part and the underlap part continuously on both the left and right edges of the board part, respectively. The waterproofness of the vertical joint can also be improved.

  Next, the following means is used in the present invention as a mounting bracket applied to the wall tile described above. That is, a rail-like metal fitting for mounting a plurality of wall tiles on the wall base in parallel on the left and right sides, a vertical plate-like mounting portion fixed to the wall base, and the wall body from one side of the mounting portion A receiving portion horizontally provided with a length corresponding to the stepped portion on the back side of the tile for tiles, and hooked on the lower slit of the wall tile vertically upward from the end of the receiving portion A hook portion.

  In this means, the mounting portion is a portion for fixing the metal fitting to the wall edge column of the wall base with a nail or a screw. The hook portion is a portion that is vertically inserted into the slit on the lower side of the tile, and the receiving portion is a portion that supports the step portion on the back side of the tile when the hook portion is inserted into the slit.

  Further, in such a mounting bracket, a hanging portion into which the underlap portion of the wall tile is inserted between the mounting portion and the mounting portion may be provided vertically at the end of the receiving portion. The hanging portion restrains the underlap portion and holds the tile in a vertical posture together with the lower hook portion.

  Furthermore, the mounting bracket may be integrated by welding or the like, but is preferably formed by bending a single metal plate. This is because a mounting bracket having a uniform strength can be produced in order to obtain a long rail mounting bracket having a left and right length of several tens of centimeters to several meters.

  In addition, as mentioned above, the waterproofness of the joints is ensured by fixing the tiles to the mounting brackets together, but in severe weather such as storms, there is a slight amount on the back side of the tiles. It is assumed that rainwater enters. Therefore, in the present invention, means for producing the mounting bracket by bending a corrosion-resistant plated steel sheet is used. According to this means, the necessary strength can be obtained, and even if rainwater enters the tile back side or the tile back side is condensed, the mounting bracket does not rust and can maintain durability for a long period of time. . In this respect, there is also stainless steel as a metal having the same strength and rust prevention property. In the present invention, other metals are not excluded, but from the viewpoint of cost, the above-described corrosion-resistant plated steel sheet is more advantageous than stainless steel. is there.

  Subsequently, the following means is used in the present invention as the wall structure in which the above-described wall tile and the mounting bracket are combined. That is, a plurality of the mounting brackets are arranged in series in the horizontal direction on the wall base, and further provided in parallel in a plurality of stages in the vertical direction, and the vertical interval between the mounting brackets is a hanging portion of the upper mounting bracket. Insert the underlap part of the wall tile from diagonally below between the mounting part and the vertical part so that the hanging part of the upper mounting bracket is inserted into another slit on the upper side of the tile. The back side stepped portion is positioned above the receiving portion of the lower mounting bracket, and then the hook portion of the lower mounting bracket is inserted into the slit on the lower side of the tile by its own weight. In the state, the underlap portion of the tile is constrained by the hanging portion of the upper mounting bracket, so that the interval for maintaining the tile in a vertical posture is set.

  According to this means, the tile can be held in the vertical posture by supporting the tile by the lower hook portion while restraining the underlap portion of the tile by the hanging portion.

  On the other hand, as another means, when a wall body is constructed by combining a tile not having a slit on the upper side and a mounting bracket having no drooping portion, a plurality of the mounting brackets in the lateral direction on the wall base. In addition to being provided in series in a plurality of stages in parallel in the vertical direction, the upper and lower intervals of the mounting brackets can be positioned between the upper and lower mounting brackets while maintaining the tile in a vertical posture. The hook portion of the mounting bracket is inserted into the slit on the lower side of the tile to be hooked, and the underlap portion of the tile is brought into contact with the overlap portion of the upper tile and is restrained. , The interval for maintaining the tile in the vertical posture is set.

  According to this another means, the underlap portion of the tile is constrained by the agreement with the overlap portion of the tile on the upper level, and this is chained by the tiles of all the steps, so that the above-described drooping portion as a whole. It is possible to construct a wall having the same strength as when the attached mounting bracket is applied.

  According to the present invention, as the wall tile to be applied to the hook-type mounting bracket, a vertical hook-hanging slit is provided on the lower side thereof, so that the tile can be easily operated by hooking the hook to the slit. Can be securely held in a vertical posture. In addition, since the slit is parallel to the planar direction of the tile, it is easier to form the slit than to form an inclined concave portion.

  Similarly, since the mounting bracket of the present invention is formed by molding a metal plate into a substantially H-shaped cross section, the wall tile can be easily mounted while maintaining a simple structure while maintaining a vertical posture. The tile can be securely fixed.

  And since the wall body structure of this invention combines these tiles for wall bodies and an attachment metal fitting, a wall body can be constructed | assembled with sufficient workability.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a wall structure according to an embodiment of the present invention. In the figure, 1 is a wall tile, and 2 is its mounting bracket. The mounting bracket 2 is fixed to a trunk edge column 3 provided at an appropriate interval as a wall base with nails, screws, or the like. The mounting bracket 2 is in the form of a long rail that is long on the left and right, and a plurality of mounting brackets 2 are provided on the left and right according to the span of the wall to be constructed, and are provided in a number of steps corresponding to the height of the wall. Then, the wall tiles 1 are sequentially hooked on the mounting bracket 2 provided in this manner from the lower stage to construct the wall body.

  FIG. 2 is a perspective view of the wall tile 1, (a) is a perspective view seen from the front side, and (b) is a perspective view seen from the back side. As shown in the figure, the wall tile 1 has an underlap portion 1a at the upper edge and the right edge, and an overlap portion 1b at the lower edge and the left edge. The underlap portion 1a and the overlap portion 1b are in a reciprocal relationship, and are formed to be approximately half the thickness of the substrate portion 1c at the center of the tile.

  And the slit fixed to the attachment metal fitting 2 is provided in the lower side and the upper side of the tile 1 for walls, and when this is demonstrated with the expanded sectional view shown in FIG. The overlap portion 1b is continuously formed on the lower edge of the substrate portion 1c via the back surface side step portion 1d, and the total length of the even angle C that is the inner angle between the overlap portion 1b and the back surface side step portion 1d. The slit 1e is provided so as to cut vertically to the substrate part 1c side.

  Similarly, on the upper side of the tile, the slit 1g is formed in the substrate portion 1c at the even angle C between the underlap portion 1a and the surface-side step portion 1f that are continuously formed on the upper edge of the substrate portion 1c via the surface-side step portion 1f. It is provided so as to cut vertically to the side.

  Each of the slits 1e and 1g has a predetermined depth and is provided across the entire width of the left and right sides of the tile. Therefore, both left and right ends are opened. Further, a recess 1h is provided on the lower side of the back surface of the substrate portion 1c so as to absorb the thickness of the mounting portion of the mounting bracket 2 described later.

  The approximate dimensions of the tiles exemplified here are 320 mm in overall width, 255 mm in vertical width, and 21.5 mm in thickness. The underlap portion 1a has a horizontal width of 300 mm (amount of protrusion from the substrate portion 1c of 15 mm), a vertical width of 230 mm (amount of protrusion of the substrate portion 1c of 20 mm), and a thickness (synonymous with the thickness of the back surface side step portion 1d) of 11 mm. It is. On the other hand, the overlap portion 1b has a horizontal width of 300 mm (amount of protrusion from the substrate portion 1c of 20 mm), a vertical width of 240 mm (amount of protrusion of the substrate portion 1c of 25 mm), and a thickness (synonymous with the thickness of the surface side step portion 1f). .5 mm. Further, regarding the slits 1e and 1g, the lower slit 1e has a depth of 10 mm and a width of 1.2 mm, and the upper slit 1g has a depth of 5 mm and a width of 0.7 mm. Furthermore, the recess 1h provided on the back surface of the substrate portion 1c is provided with a width of 40 mm and a depth of 0.5 mm upward from the back surface side step portion 1d. These dimensions are merely examples, and it goes without saying that the present invention is not limited to tiles having these dimensions.

  Next, details of the mounting bracket 2 will be described with reference to a cross-sectional view shown in FIG. The mounting bracket 2 is formed by bending a metal plate to have a corrosion resistance, and is roughly H-shaped in cross section. A vertical plate-shaped mounting portion 2a and a receiving portion 2b provided horizontally from one surface of the mounting portion 2a. And a hook portion 2c vertically upward from the end of the receiving portion 2b. Further, in this embodiment, a hanging portion 2d is provided vertically downward from the end portion of the receiving portion 2b, continuously from the hook portion 2c. Among these, the upper half part of the attaching part 2a and the hook part 2c are two-layered, and the lower half part of the attaching part 2a, the receiving part 2b, and the drooping part 2d have a single structure. And this mounting bracket 2 has the said cross-sectional shape over the left-right direction full length, and is formed in the elongate rail shape as mentioned above.

  The dimensions of the mounting bracket 2 are also exemplified. As applied to a tile having the above dimensions, the height of the mounting portion 2a is 65 mm, the width of the receiving portion 2b is 10 mm, and the receiving portion of the hook portion 2c. The height based on 2b is 8 mm, and the length based on the receiving portion 2b of the hanging portion 2d is 25 mm.

  The metal material is stainless steel, and a corrosion-resistant plated steel sheet having a plating layer made of zinc, aluminum, and magnesium can be cited as a good example.

  FIG. 5 is an enlarged cross-sectional view showing a state in which the tile 1 is attached to the attachment fitting 2. As shown in the figure, the upper tile 1 has a hook portion 2c hooked to the lower slit 1e by its own weight, and in this state, the back surface side step portion 1d is supported by the receiving portion 2b. And the overlap part 1b of a lower edge is extended below rather than the drooping part 2d.

  At the same time, the lower tile 1 has the upper edge underlap portion 1a inserted into the space 4 between the hanging portion 2d and the mounting portion 2a, and the forward falling is restrained by the hanging portion 2d. Moreover, the overlap part 1b of the upper stage tile 1 has overlapped with the agreement on the surface side of this underlap part 1a.

  In this way, according to the combination of the tile 1 and the mounting bracket 2 described above, the wall body is maintained while holding the tile 1 in a vertical posture by a simple operation of hooking the tile 1 to the hook portion 2c of the mounting bracket 2. Can be built. In addition, since the recess 1h is provided on the back surface of the tile 1 to absorb the thickness of the upper half of the two mounting portions 2a of the mounting bracket 2, even when the mounting bracket 2 is formed by bending a metal plate, The wall body can be constructed with the front surface being flush with the upper and lower tiles without any step difference.

  By the way, in the combination of the tile 1 and the mounting bracket 2 described above, the slit 1g on the upper side of the tile 1 does not function when the tile 1 is hooked on the mounting bracket 2 and fixed. However, in this structure, since the underlap portion 1a at the upper edge of the tile 1 is restrained by the hanging portion 2d of the mounting bracket 2, when the tile 1 is fixed, the lower slit 1e of the tile 1 is connected to the mounting bracket 2 It is necessary to insert the underlap portion 1a at the upper edge of the tile 1 inside the hanging portion 2d of the mounting bracket 2 before being hooked on the hook portion 2c. Therefore, in the present embodiment, a slit 1g is provided on the upper side of the tile 1 so as to allow the drooping portion 2d to escape.

  In this regard, the procedure for attaching the tile 1 according to the present embodiment will be described with reference to FIG. 6. First, the tile 1 is inclined with respect to the mounting bracket 2 provided at a predetermined interval on the wall base and arranged in parallel. The upper edge underlap portion 1a is inserted into the inside of the hanging portion 2d from below (a). Next, while returning the tile 1 to the vertical posture, the back surface side step portion 1d is lifted to a position where it does not interfere with the hook portion 2c of the lower mounting bracket 2 (b). Then, by inserting the underlap portion 1a deeper into the inside of the drooping portion 2d, the tile 1 is brought into a completely vertical posture, and alignment is performed so that the lower slit 1e corresponds to the hook portion 2c of the mounting bracket 2. (C). Finally, by slowly releasing the hand from the tile 1, the hook portion 2 c is inserted into the lower slit 1 e by the weight of the tile 1, and the attachment is completed as shown in FIG. 5 (d).

  Thus, in the case where the mounting bracket 2 has the drooping portion 2d, the drooping portion 2d in the process of inserting the underlap portion 1a of the upper edge of the tile into the inside ((b) and (c) of FIG. 6). In order to avoid interference due to the above, a slit 1g is also provided on the upper side of the tile.

  If this is regarded as the space between the upper and lower sides of the mounting bracket 2, the hook portion 2c is hooked on the slit 1e on the lower side of the tile and the upper edge underlap portion 1a is restrained by the hanging portion 2d as shown in FIG. The underlap portion 1a is set at an interval at which the underlap portion 1a is brought into contact with the overlap portion 1b of the upper tile.

  In addition, if the procedure of FIG. 6 is performed in reverse, the tile 1 can be removed from the mounting bracket 2. Accordingly, it is possible to easily replace the tile 1 with another one at the time of renovation and further dismantle the wall body.

  On the other hand, the tile 1 and the mounting bracket 2 can also omit the upper slit 1g and the hanging portion 2d as a modification. In this case, the upper and lower intervals of the mounting bracket 2 can be positioned between the upper and lower mounting brackets 2 while the tile 1 is in a vertical posture, and the hook portion 2c of the mounting bracket 2 is placed in the slit 1e below the tile by its own weight. The tile 1 is kept in a vertical posture by being inserted and hooked, and the underlap portion 1a of the tile 1 is brought into contact with and constrained by the overlap portion 1b of the tile 1 at the upper stage. Set the interval to be used.

  Even in this case, the underlap portion 1a of the tile 1 is constrained by the agreement with the overlap portion 1b of the tile 1 that is one level above, and this is chained by the tiles of all the steps, so that as a whole, It is possible to construct a wall body having the same strength as when the mounting bracket with the hanging portion is applied.

  Further, when the slit 1e on the lower side of the tile is provided over the entire length, the tile can be slid left and right along the hook portion 2c to adjust the position. However, as shown in FIG. On the lower side, a slit 11 may be formed with both left and right ends closed. Of course, the hook portion 21 of the mounting bracket 20 can also be provided with a plurality of hooks 21 having the same length as the slit 11 in the longitudinal direction. According to another embodiment of the present invention, the sliding of the left and right of the tile is restricted with the slit 11 hooked on the hook portion 21, so that the left and right sliding is suppressed for a long time for each tile, and the initial state of construction is ensured. Can be held in.
