Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for joining exterior face plates on horizontal roofs, exterior walls, etc. of buildings.

[Conventional technology]

Conventionally, as a face plate joining device for the exterior of a horizontal roof, there has been one shown in Japanese Patent Application Laid-Open No. 59-233060. The face plate joining device is shown in FIGS. 10 to 14.
As shown in the figure, a large number of roof face plates 1 are horizontally roofed on rafters on the building frame side via base material using hangers (not shown), and the face plates 1 are attached in the direction of the eaves, that is, in the vertical direction. They are joined together, and the lateral joining is done as follows. That is, the edges of adjacent double-sided boards 1 are placed opposite each other with a joint gap 2 between them, and a waste board 3 that spans both sides of the joint gap 2 is arranged on the back side of the double-sided board 1. The protrusions 4 protruding toward the surface side provided at 3 are arranged opposite to each other on the outside in the lateral direction of the joint gap 2, and the tips of the left and right hypotenuses 6 of the joint 5, which has a substantially horizontal K-shaped cross section, are connected to the protrusions 4. 4
are engaged and held, respectively, and loosely insert the edge of the double-sided plate 1 between the horizontal side 7 and the oblique side 6 of the joint 5,
The horizontal side 7 located above the double-sided plates 1, 1 is held from the front side by the joint cover 8, and the opposite side edges 9 of the joint cover 8 are connected to the horizontal side 7 and the double-sided plate 1.
By inserting the end edge portions of these face plates 1 between the horizontal side 7 and oblique side 6 of the joint 5, the joint cover 8 is interposed.

Further, as shown in FIGS. 11 and 12, engaging portions 10 and 11 are formed on the upper and lower sides of the disposable plate 3, and engaging portions 12 and 1 are formed on the upper and lower sides of the joint cover 8.
3 is formed, and the upper engaging portions 10 and 12 are engaged with the upper engaging portion 14 of the intermediate face plate 1, together with the engaging portion on the lower side of the face plate adjacent above, and the lower engaging portion By engaging the portions 11 and 13 with the upper engaging portion of the downwardly adjacent face plate and the lower engaging portion 15 of the intermediate face plate 1, the face plate 1 to be laterally roofed is vertically leveled. They are joined with a slope, and the face plates 1 are arranged in a staggered manner.

FIG. 14 shows another conventional exterior face plate joining device. This joining device has a groove 16 in the width direction,
A first joint plate 3 is formed by bending and forming a single metal plate with the upper and lower sides 18 and 19 doubled so that the outer side of the concave groove 16 is inclined backwards and the joint plate 3 has a cross section that is almost an inverted E-shape.
This device has the same configuration as the exterior face plate joining device shown in FIGS. 10 to 13, except that it is used instead of the joint and joint cover shown in FIGS. 0 to 13.

[Problem that the invention seeks to solve]

The conventional exterior face plate joining device described above connects the flat opposing edges of horizontally adjacent face plates with a joint and a joint cover, or with a joint plate having an approximately inverted square-shaped cross section.
The type shown in Figures 10 to 13 requires a joint and a joint cover, so the number of parts is large, and the type shown in Figure 14 has joint plates on the top and bottom sides. Since the metal plate was bent in double layers, a large metal plate was required and the processing was troublesome.The joints and joint covers or joint plates were expensive, and both edges of the face plate were bent on the front and back sides. Due to the sandwiching, the joining operation is troublesome and time consuming, and the apparatus becomes expensive. Furthermore, since both end edges of the face plate and the joint cover or joint plate are in contact with each other with a step in the front and back direction, dust and dirt can easily adhere to and accumulate on the contact parts, causing a poor appearance.
Since the deposit 17 contains water, there is a problem in that the paint deteriorates early, leading to the occurrence of rust.

The present invention was made to solve the above-mentioned problems, and it reduces the cost of parts and the work required for joining work, and also prevents dust and dirt from accumulating between the joint plate and the face plate, so it can be used for a long time. It is an object of the present invention to provide a face plate joining device for the exterior of a building that does not damage the appearance or cause rust due to waving.

[Means for solving problems]

The face plate joining device for the exterior of a building according to the present invention is fixed to the building frame side and laterally roofed, and a joint gap of a predetermined width is provided between the edge portion bent to the back side of the laterally adjacent double-sided plate. A sacrificial board facing each other and spanning both sides of the joint gap is arranged on the back side of the double-sided board, and a joint board made of an elastic material supported on the surface of the sacrificial board is positioned in the vertical and horizontal directions in the joint gap. and is pressed by the face plate.

[Effect]

The exterior face plate joining device according to the present invention does not sandwich the opposing edges of laterally adjacent double-sided plates from the front and back sides with joint plates, but instead connects the opposite edges of the adjacent double-sided plates to the back side of the adjacent double-sided plates. The bent edges are placed opposite to each other with a joint gap between them, and a waste board that spans both sides of the joint gap is placed on the back side of the double-sided board, and an elastic plate is supported on the surface of the waste board. Position the joint plates made of the material both vertically and horizontally in the joint gaps,
Because it is pressed by the face plate,
Because the joint plates are pressed by the vertically adjacent face plates, there are no gaps between the contact surfaces, making it difficult for water to enter the interior.Even if some rainwater does enter through the gaps in the joint plates, The rainwater flows down the surface of the joint plate, and even if it slightly leaks onto the surface of the waste board, the ridges of the waste board prevent it from leaking to the outside in the lateral direction of the waste board, and there is no difference in level from the joint board and the waste board. Since the rain is guided downward to the surface of the adjacent face plate, no leakage occurs.

In addition, since the joint plate may have a simple shape made of an extrusion molded product of rubber or synthetic resin, this invention was first published in Japanese Patent Application No. 118872-1987 (filed on May 18, 1988, JP-A-63-1989). 284347) proposed in which joint plates were made of bent metal products, it can be made at a lower cost, and it is easier to carry out the construction without having to bend the upper and lower ends of the joint plates in advance. Because it can be easily bent, it is easy to join the face plates, and capillary action is less likely to occur between the joint plate made of elastic material and the face plate and waste plate made of metal plates than between metal plates. This makes it difficult for dust and dirt to accumulate between the face plate and the joint plate, and therefore, the appearance is less likely to be damaged.

〔Example〕

The first embodiment of the present invention will now be described with reference to FIGS. 1 to 3.

In FIG. 1, reference numeral 1 denotes a face plate made of a painted net plate or the like, and the face plate 1 is provided with an edge portion 22 bent at right angles from the plate surface 21 to the back side. A folded portion 22a is formed. 3

It has a side wall 30 corresponding to the bent edge 22 on the back surface side, and has a flat surface 31 extending from the lower end of the side wall 30.

Incidentally, since the joint plate 20 shown in FIG. 3 is made of an elastic material, the engaging portions 24 and 25 of the joint plate corresponding to the engaging portions 12 and 13 in FIG.
is used by folding it by hand as shown in the third figure. In addition, in the case of a single molded product,
It is formed in advance into the shape shown in the third figure.

As shown in FIGS. 1 and 2, the exterior face plate joining device having each member configured as described above has the following features:
The face plate 1 is fixed to the rafters or the like on the frame of the building using hangers in the same way as in the conventional case, and the roof is laterally roofed.
End edges 22 of laterally adjacent double-sided plates 1 are arranged to face each other with a joint gap 2 of a predetermined width in between. A sacrificial board 3 is disposed on the back side of the double-sided board 1 so as to straddle both sides of the joint gap 2. A joint board 20 is fitted into the joint gap 2, and the back surface of the joint board 20 is supported by the front surface of the sacrificial board 3 and bonded with an adhesive (not shown).
The edge portion 22 and folded portion 22a of the double-sided board 1 are pressed onto both sides of the side wall 30 and flat surface 31 of the joint board 20, and the joint board 20 is further pressed against the upper and lower end portions 24 as shown in FIG. , 25 is bent and the scrap board 3
are overlapped with the engaging parts at the upper and lower ends of the upper and lower ends, respectively, and
It has a step in the downward direction and is engaged with the engaging portion of the adjacent face plate. Therefore, the joint plate 20 is positioned and fixed in the horizontal and vertical directions by the adhesion, abutment, and engagement, and is pressed by the edge portions 22 and folded portions 22a of the face plates 1, 1.

In addition, when both side surfaces of the joint board 20 and the edge part 22 of the double-sided board 1 are made to contact|abut as needed, the adhesion|attachment of the joint board 20 to the waste board 3 may be omitted. Further, the joint plate 20 may be formed in advance into the shape shown in FIG. 3. Then, the face plate 1 is on the top,
They are arranged in a staggered manner with the joints positioned differently from those adjacent below, and the surface of the joint board 20 is placed on the same plane as the top plate of the double-sided board 1, giving it a good appearance. .

FIG. 4 shows a modification of the first embodiment, and this modification is more effective than the one shown in FIG.
The only difference from the first embodiment is that the number 3 is increased, but according to this configuration, there is a substantially triangular cross section between the edge 22 of the double-sided board 1 and the protrusion 23 of the waste board 3. A capillary phenomenon prevention gap 26 is formed. The same reference numerals in FIG. 4 as in FIG. 1 indicate corresponding parts.

In the second embodiment, as shown in FIGS. 5A, B, and 6, a folded part 22a is formed as a part of the edge part 22 from the tip edge of the edge part 22 of the double-sided plate 1 to the lower part of the face plate 21. There is. Further, the joint plate 20 is formed to have a width wider than the joint gap 2, and as shown in FIG. 6A, recesses 28 having a substantially inverted trapezoidal cross section are formed at both ends of the upper surface.

The joint board 20 is supported on the surface of the waste board 3, and both sides of the joint board 20 are connected to the protrusions 2 of the waste board 3.
3, and both sides of the joint plate 20 protruding to both sides of the joint gap 2 are inserted between the face plate 1 and the waste plate 3, and the bottom of the recess 28 of the joint plate 20 is connected to the side part of the face plate 21. A joint plate 2 is supported by the folded parts 22a and is placed between the folded parts 22a and the waste board 3.
0 is sandwiched, so that the joint plate 20 is positioned and fixed in the lateral direction.

Note that the configuration of the second embodiment other than the above is the same as that of the first embodiment.
This is similar to the example. And in the second example,
A folded portion 2 provided at the tip edge of the edge portion 22 of the face plate 1
Since the joint plate 20 is pivotally connected between the joint plate 2a and the sacrificial plate 3, the joint plate 20 can be reliably positioned and fixed by being held by the protruding edge 23a of the sacrificial plate 3.
In addition, what is shown in FIG. 5B is a partially cutaway perspective view of the joint plate 20 in which no recess is formed, and in this case, by using a relatively soft material,
The joint plate 20 interposed between the face plate 1 and the waste plate 3 is the sixth
Because it undergoes elastic deformation in almost the same way as the recess shown in Figure A,
Infiltration of rainwater can be reliably prevented at the contact points.

FIGS. 7, 8, and 9 show different modifications of the second embodiment. The one shown in FIG.
8 is formed on the upper part of the joint plate 20, and the side wall 28a of the recess 28 is supported by the side edge of the folded portion 22a of the face plate 1. In the one shown in FIG. 8, a recess 28 having a rectangular cross section is formed on the upper surface of the joint material 20, and the bottom of the recess 28 is supported by the lower edge of the end edge 22 of the face plate 1. Furthermore, in the configuration shown in FIG. 9, a recess 28 having an L-shaped cross section facing inward and an inverted L-shape opposite to that shown in FIG. from the end edge 22 of the plate surface 2
The joint plate 20 is supported by the side edge of the support portion 27 extending in one extension direction, and the surface of the center portion in the width direction of the joint plate 20 is arranged on the same plane as the surface of the plate surface 21 of the face plate 1. Note that the configurations shown in FIGS. 7, 8, and 9 other than those described above are the same as in the second embodiment,
The same reference numerals as in FIG. 5 in FIGS. 7 to 9 indicate corresponding parts. In the practice of the present invention, when the color of the joint plate 20 is different from the color of the face plate 1, a decorative cover of the same color as the face plate may be covered.

Although the present invention has been described above in the case where it is applied to a horizontal roof, the present invention can also be used on an exterior wall of a building by horizontally roofing the face plate and having the joint plates extending substantially vertically.

〔Effect of the invention〕

As explained above, according to the present invention, the edges of the laterally adjacent double-sided boards that are bent toward the back side are made to face each other with a joint gap provided between them, and to straddle both sides of the joint gap. A waste board is arranged on the back side of the double-sided board, and a joint board made of an elastic material supported on the surface of the waste board is positioned over both sides of the joint gap or fitted into the joint gap, and is positioned vertically and horizontally. Since it is pressed by the face plate, the elastic support of the joint plate prevents rainwater from penetrating, and even if rainwater mainly flows down the joint plate surface and leaks slightly onto the surface of the waste board, the waste board Because of the protrusions, rain does not leak to the outside in the lateral direction of the waste board, and is guided from the joint board and the waste board to the surface of the face plate adjacent to the lower part with a step difference, thereby preventing rain from leaking.

In addition, the joint plate can be made of a simple shape made of extrusion molded rubber or synthetic resin, so it can be made at low cost.Furthermore, the upper and lower ends 24 and 25 of the joint plate only need to be bent by hand during installation, making it easier to use than conventional joint plates. Since there is no need to perform such bending process in advance, the work of joining the face plates can be made easier.Furthermore, between the joint plate made of an elastic material and the face plate and waste plate made of a metal plate, the elastic force of the joint plate keeps the face plate Since the face plate and the joint plate are in close contact with each other, capillary action is difficult to occur, and therefore dust and dirt are difficult to accumulate between the face plate and the joint plate, which slows down the occurrence of rust and reduces the appearance. effective.
