Description

TECHNICAL FIELD The present invention relates to a mounting structure for applying decorative material to the outer wall of a building.

Various decorative materials are applied to the outer walls of buildings. For example, a band-shaped decorative material called a decorative dozashi is used as a parting material that hides the boundary between the first and second floors on the outer wall of a building. Instead of fixing directly to the outer wall using screws, etc., the decorative dojishi is attached to the outer wall by locking it to the mounting bracket fixed to the outer wall so that the heads of the screws do not appear on the exterior. It can be attached to the outer wall by hiding the metal fittings.

As a mounting structure for such a decorative material, Patent Document 1 discloses a structure for mounting an architectural exterior decorative panel to an outer wall surface using a mounting bracket, in which an engaging convex portion of the decorative panel is fixed to the building skeleton. A mounting structure is described in which the mounting bracket is pushed into a receiving recess of the mounting bracket from above for fixing. In addition, Patent Document 2 discloses a mounting structure for attaching a decorative material to a building frame using a mounting bracket, in which the hanging part provided by the decorative material is attached to a receiving part provided with the mounting bracket and having an opening facing upward. A mounting structure for insertion from above is described.

JP-A-7-269067 Japanese Patent Application Laid-Open No. 2002-013286

The mounting structure described in Patent Literature 1 has a problem that it does not have a structure for forcibly preventing the vertical movement of the decorative panel after the decorative panel is mounted.

In the mounting structure described in Patent Document 2, the receiving portion of the mounting bracket has a tongue-shaped piece inside, and the protruding portion provided on the hanging portion of the decorative material is inserted into the receiving portion over the tongue-shaped piece. As a result, the suspended portion is prevented from slipping upward from the receiving portion after the decorative material is fixed to the mounting bracket. The mounting bracket of Patent Document 1 has a shape suitable for manufacturing by extrusion molding of aluminum or the like, whereas the mounting bracket of Patent Document 2 is manufactured by pressing a stainless steel plate, and by pressing, the decorative material is formed. It is easy to form a tongue-shaped piece as a pull-out prevention means. However, in the mounting structure of Patent Document 2, it is necessary to use a countersunk head screw so that the projecting portion of the screw that fixes the mounting bracket to the building does not interfere with the mounting of the decorative material. The manufacturing cost is increased because the screw holes are tapered for embedding and the body plate is lifted from the outer wall of the building by the thickness of the taper.

If you use more common panhead screws to secure the mounting bracket to the building, you will not need to make complicated screw holes. is restricted. In Patent Document 1, a screw hole is provided directly below the receiving portion. On the other hand, when the mounting bracket is manufactured by press working as in Patent Document 2, in order to reduce the size of the mounting bracket while maintaining the strength, the lower part of the upper receiving part is punched out and bent. Since a punched hole remains directly below the upper receiving portion, a screw hole cannot be formed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting structure for a decorative material which is provided with means for preventing the decorative material from coming off and which can be installed using a pan head screw or the like. do.

A mounting structure for a decorative material according to the present invention is a mounting structure for mounting a decorative material on an outer wall of a building using a mounting bracket. The mounting bracket includes a main body plate, connecting portions extending forward from both left and right ends of the main body plate, and end plates extending substantially parallel to the main body plate in the width direction from front ends of the connecting portions. have The body plate includes a first receiving portion having an opening facing upward, and a screw hole for inserting a fixture. The end plate includes a pressing portion that presses the decorative material forward. The decorative member has a first hanging portion inserted into the first receiving portion from above, and is pushed forward by the pressing portion while the first hanging portion is inserted into the first receiving portion. .

Here, the front refers to the direction opposite to the building in the state where the facing materials and mounting brackets are installed. Further, in this specification, the term "rear" refers to the opposite direction to the front, and the terms "up, down, left, and right" refer to the directions viewed from the front (outdoor side) with the decorative materials and mounting brackets installed.

Preferably, the mounting bracket is made of one metal plate.

Preferably, the pressing portion is formed of a tongue-shaped piece that is punched out from the end plate and protrudes obliquely forward and downward.

According to the mounting structure of the decorative material of the present invention, the body plate of the mounting bracket is recessed one step backward from the end plate. There is no interference with the heads of screws, etc. when installing materials. In particular, when the second hanging portion is provided on the lower side of the first hanging portion, and the mounting bracket has the first receiving portion and the second receiving portion corresponding to the hanging portion, the second hanging portion on the lower side is screwed. Interference problems with the head may arise and the structure of the present invention is particularly effective. Further, in a state in which the first hanging portion is inserted into the first receiving portion, the first hanging portion is pressed forward by the pressing portion and sandwiched between the front inner wall of the first receiving portion. The portion is prevented from slipping upward from the first receiving portion.

1 is a cross-sectional view showing a mounting structure for a decorative material according to an embodiment of the present invention; FIG. It is A: Front view, B: Bottom view, C: Right side view of the mounting bracket in one Embodiment of this invention. 1 is a vertical cross-sectional view of a decorative material in one embodiment of the present invention; FIG.

Referring to FIG. 1, a decorative material mounting structure 10 of one embodiment will be described. The decorative material of this embodiment is a decorative trunk. The decorative material 30 is constructed so as to hide the boundary between the outer wall 42 of the first floor of the building and the outer wall 43 of the second floor. First, the mounting bracket 20 is fixed to the building skeleton 41 using fasteners such as screws 44 and attached to the building outer wall surface 40 . The decorative material 30 is locked to the mounting bracket by inserting the hanging parts 32 and 33 into the receiving parts 22 and 24 of the mounting bracket from above. Since the decorative material hides the entire mounting bracket, the mounting bracket does not appear in the appearance after construction. In addition, a waterproof material may be applied to the upper back surface side of the decorative material 30 to close the gap with the outer surface of the building.

Referring to FIG. 2, the mounting bracket 20 has a body plate 21, left and right connecting portions 27, 27, and left and right end plates 28, 28. As shown in FIG. The connecting portion extends forward from both left and right ends of the body plate. The end plate extends laterally outward from the front end of each of the left and right connecting portions in the width direction.

The body plate 21 is a flat portion fixed to the outer wall surface 40 of the building, and includes a first receiving portion 22 and a second receiving portion 24 having openings facing upward. The upper first receiving portion is formed by punching out a portion of the body plate into a substantially rectangular shape, leaving the upper side, and bending the punched portion. A punched hole 23 remains on the lower side of the first receiving part. The second receiving portion on the lower side is formed by punching out a portion of the body plate into a substantially rectangular shape, leaving the lower side, and bending the punched portion. A punched hole 25 remains on the upper side of the second receiving part. Both the first receiving portion and the second receiving portion have upward openings into which the first drooping portion 32 and the second drooping portion 33 of the decorative material 30 are inserted.

The number of receiving parts may be one, but preferably two receiving parts are arranged vertically. This is because the posture of the engaged decorative material 30 is stabilized. Further, the problem of interference with the screw head is highly likely to occur when two or more hanging portions are provided in the vertical direction and two or more corresponding receiving portions are provided. Therefore, the mounting structure of this embodiment is particularly preferably applied when the decorative material has two or more hanging portions in the vertical direction and the mounting bracket has two or more corresponding receiving portions.

The body plate 21 is provided with screw holes 26 for fasteners. Two or more screw holes are preferably provided. This is because the posture of the mounting bracket 20 is stabilized when fixed to a building. The position where the screw hole is provided is not particularly limited. The shape of the screw hole does not require tapering or the like, and may be a hole that is simply punched out.

The connecting portions 27 , 27 extend forward from both left and right ends of the body plate 21 .

The end plates 28, 28 extend laterally outward from the front ends of the left and right connecting portions, respectively. The end plates are parallel to the body plate 21 . Note that "parallel" does not have a strict meaning, but may be roughly parallel.

The end plate 28 includes a pressing portion 29 that presses the decorative material 30 forward. Preferably, the pressing portion is formed of a tongue-shaped piece that is formed by punching out a portion of the end plate into a substantially rectangular shape, leaving the upper side, and protruding obliquely forward and downward by bending. The pressing portions are positioned on both sides of the first receiving portion 22 and both sides of the second receiving portion 24 . The pressing portion elastically presses forward the drooping portions 32, 33 of the decorative material inserted into the receiving portions 22, 24 against the inner walls in front of the receiving portions. As a result, the decorative material 30 locked to the mounting bracket 20 is firmly fixed without rattling. Further, since the tongue-shaped piece of the pressing portion protrudes forward and obliquely downward from the end plate, it is possible to prevent upward movement of the drooping portion once inserted into the receiving portion.

From the shapes of the body plate 21, the connecting portion 27, and the end plate 28, when the mounting bracket 20 is viewed as a whole, the body plate portion is recessed rearward from the end plate. If the depth of the recess, that is, the distance between the front surface of the main body plate and the front surface of the end plate in the direction perpendicular to the outer wall of the building, is larger than the amount of protrusion of the head of the screw 44 from the front surface of the main body plate, when attaching the decorative material 30, Since the rearmost part (building side) of the back surface of the decorative material is always in front of the screw head, the two do not interfere with each other. The depth of the recess is preferably 3 to 5 mm because the head of the screw commonly used at construction sites projects less than 3 mm from the front surface of the main body plate.

The mounting bracket 20 is preferably made of a single metal plate and formed by press working. The type of metal is not particularly limited as long as it can be press-worked, and for example, a steel plate, a stainless steel plate, an aluminum plate, or the like can be used. If the mounting bracket is formed from a single metal plate, there is no risk of deterioration in strength due to deterioration of joints. In addition, molding of the mounting bracket by press work facilitates molding of the pressing portion 29 in particular. The press work includes cutting, punching, drilling, notching, bending, folding, and the like.

The overall contour of the mounting bracket 20 is preferably substantially rectangular, for example, without missing or protruding portions. It is because it is hard to deform|transform at the time of handling. Further, in order to reduce the size while maintaining the required strength, it is preferable that the punched hole remains in the center of the receiving portion. That is, the punched hole 23 for forming the upper first receiving portion 22 is located below the first receiving portion, and the punching hole 25 for forming the lower second receiving portion 24 is located below the second receiving portion. preferably remain above the

Referring to FIG. 3, the decorative material 30 is a long member having a uniform cross section and extending in a direction perpendicular to the plane of FIG. The decorative material 30 has a design surface 31 that appears in the appearance after construction as the front side, and has a first drooping portion 32 and a second drooping portion 33 that protrude from the back surface and extend downward. The first hanging portion and the second hanging portion are respectively inserted into the first receiving portion 22 and the second receiving portion 24 of the mounting bracket 20 from above. The decorative material is usually made of an inorganic material, preferably a cement-based extruded product having a specific gravity of about 0.75 to 2.0. The decorative material 30 is attached to the receiving portions 22 and 24 by placing the hanging portions 32 and 33 against the end plate 28 of the mounting bracket fixed to the outer wall surface 40 of the building and moving downward along the end plate. It can be inserted from above.

The mounting structure of the decorative material of the present invention is applied to decorative materials such as parting materials, decorative gables, fascias, gables, etc., which are used for the outer walls of general residential buildings.

Moreover, the present invention is not limited to the above-described embodiments, and various modifications are possible within the technical scope of the present invention.

For example, an example of the mounting bracket is shown in FIG. 2 of the above embodiment, but since there is no restriction on the position of the screw hole 26 in the mounting bracket used in the present invention, even if the length in the vertical direction is further shortened, good. As a result, it can be used in combination with a decorative material having a narrower vertical width.
