The left side of the outer wall plate is combined with the lower side of the upper outer wall plate 40A (and the lower outer wall plate 40B), and a vertical gap S2 is formed at the joint.
Then, as understood from the figure, the horizontal gap S1
And the gap S2 in the vertical direction are continuous gaps.

[0007] Rainwater enters the gaps S1 and S2. However, the caulking agent 45A driven into the surface of the lower solid mounting portion 44A on the upper side of the lower outer wall plate 40B abuts against the back surface of the upper solid pattern forming portion 41A on the lower side of the upper outer wall plate 40A to seal. Since the portion is formed, it is avoided that the rainwater that has entered the horizontal gap S <b> 1 bypasses the vertical direction and reaches the back surface of the outer wall plate 40. Similarly, it is avoided that the rainwater that has entered the vertical gap S <b> 2 circumvents the back surface of the outer wall plate 40 by bypassing in the horizontal direction.

On the other hand, the rainwater that has entered the gap S1 moves in the horizontal direction and reaches the vertical gap S2,
It flows down through the gap S2. By the way, as shown in FIG. 7, the fastener 30 is disposed at the joint of the outer wall plate 40, but the upward fastening of the fastener 30 on the inclined surface of the solid mounting portion 42 of the upper construction board 40 </ b> A. The inner surface of the piece 33A is almost in close contact, so that rainwater flowing down the vertical gap S2 does not enter the inside of the upper fitting portion 50A (a very small amount, if any), and is locked upward. Over the upper side of the piece 33A, it flows down further, and the upward locking piece 3
It enters into a space Sa having a substantially triangular cross section formed by the front side of 3A, the front side of the downward locking piece 33B, and the back side of the upper solid pattern forming portion 41 of the upper building board 40A.

As described above, the sealing portion between the back surface of the upper solid pattern forming portion 41A on the lower side of the upper outer wall plate 40A and the surface of the lower solid mounting portion 44A on the upper side of the lower outer wall plate 40B is formed by the caulking agent 45. Therefore, the rainwater that has entered the space Sa having a substantially triangular cross section as described above does not flow downstream as it is,
a. The retained rainwater moves in the left-right direction in the space Sa, and the retaining pieces 33A, 3A
It leaks from the side edge of 3B, and flows out into the space above the horizontal caulking agent 45A cast on the surface side of the lower mounting portion 44 on the upper side of the lower construction board 40B. Rainwater that has entered the upper fitting portion 50A is also similarly locked by the locking pieces 33A,
It leaks out from 33B or the side edge of the horizontal piece 32 and flows out into the space. The space is a space that communicates with the back surface of the outer wall plate 40, and the rainwater that has entered the space goes around the back surface of the building plate 40 and damages the building plate. SUMMARY OF THE INVENTION An object of the present invention is to provide an improved fastener capable of positively avoiding rainwater from flowing into the back surface of a building board as described above, which may occur in a conventional fastener. .

A fastener according to the present invention for solving the above-mentioned problems comprises a substrate, a horizontal piece erected on the substrate, and an upward bent bent obliquely upward from the tip of the horizontal piece. A fastener comprising a locking piece and a downward locking piece bent obliquely downward from the tip of the horizontal piece, wherein at least the tip of the upward locking piece is a flat plate bent downward. It is characterized by having.

In the fastener according to the present invention having the above-described structure, the rainwater flowing down the vertical gap S2 and climbing over the leading edge of the upward locking piece is bent downward at the tip of the upward locking piece. It flows down along the surface of the flat plate portion formed as described above. The flat plate portion is in contact with the back surface side of the upper solid pattern forming portion of the upper building board, and does not spread in the horizontal direction, but actively from the gap formed at the vertical joint portion of the left and right building boards. Is discharged toward the surface side. Therefore, it is possible to prevent rainwater that has entered through gaps in the horizontal direction and the vertical direction from flowing to the back side of the building board.

The flat plate portion may be a flat surface parallel to the substrate, and may have a vertical cross-sectional shape bulging to the side opposite to the substrate. In the latter case, the contact of the flat plate portion with the back side of the west part of the upper handle can be further ensured, and the spillage of rainwater on the back side can be more reliably avoided. In a preferred aspect, the substrate is provided with an urging means for urging the plate material to be fastened toward the back surface of the downward locking piece. This makes it possible to stabilize the attachment of the plate member and the fastener. Further, in a preferred embodiment, the substrate is provided with rising pieces extending to the back side at the upper end edge and the lower end edge. Thereby, it is easy to form an air circulation space between the fastened building board and the support on the skeleton side, and it is possible to easily prevent the occurrence of dew condensation and the like.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a fastener according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a fastener.
The fastening member 10 is made of a metal material such as iron or stainless steel. The lower edge of the rectangular substrate 11 is a rising piece 1 bent to the back side, and the upper edge is inclined obliquely to the back side. And a horizontal piece 3 at the end thereof. Holes 4 and 5 are provided in the rising piece 2 and the horizontal piece 3 and are used for nailing to a base material 61 of a building.

The central portion of the substrate 11 is cut and raised in a U-shape. The cut and bent piece is first bent 90 degrees forward to form a horizontal piece 12A, and then bent obliquely upward to engage upward. The stop piece 13A is formed, and then, the flat portion 14 is bent downward from the tip of the upward locking piece 13A.
The horizontal piece 12A and the upward locking piece 13A perform the same functions as the horizontal piece 32 and the upward locking piece 33A in the conventional fastener 30 shown in FIG.

The left and right portions of the substrate 11 are also cut and raised in a U-shape, and the cut and bent pieces are bent forward by 90 degrees at substantially the same height as the horizontal pieces 12A to form horizontal pieces 12B.
Then, it is bent obliquely downward and the downward locking piece 13
B. The horizontal piece 12B and the downward locking piece 1
3B performs the same function as the horizontal piece 32 and the downward locking piece 33B in the conventional fastener 30 shown in FIG.

Below the left and right cut and raised portions, laterally extending cut and raised pieces 6 and 6 functioning as urging means.
Are formed in a cantilever shape, and the cut-and-raised pieces 6, 6 are twisted such that an upper edge 6b is located at a front position with respect to a lower edge 6a. Above the cut-and-raised portion at the center, there is formed a concave portion 7 facing the back surface, and a hole 8 is formed on the bottom surface. The depth of the recess 7 is substantially the same as the height of the rising piece 1 of the substrate 11. In the drawing, reference numeral 9 denotes a concave groove for securing the strength of the substrate 11.

FIGS. 2 and 3 are views for explaining a state in which the outer wall plate 40 shown in FIG. 8 is fastened by using the fastening fitting 10, and the outer wall plate is described in the same manner as described with reference to FIG. 40A and 40B are fastened. The relationship between the outer wall plates 40A and 40B in the fastened state is the same as that described with reference to FIG. Therefore, the same members are given the same reference numerals here, and detailed description is omitted.

As shown in FIG. 2, in the fastening member 10, the tip of the upward locking piece 13A is bent downward to form the flat plate portion 14, and when the outer wall plate 40 is fastened, The flat plate portion 14 comes into contact with the rear surface of the upper solid pattern forming portion 41A of the upper outer wall plate 40A. Therefore, the space Sa having a substantially triangular cross section as described with reference to FIG. 7 is not formed, and the rainwater flowing down the vertical gap S2 existing at the joint portion between the left and right outer wall plates is
It flows out to the surface side while flowing down the flat plate portion 14. For this reason, rainwater does not stay around the locking piece, which tends to occur in the conventional fastener, and rainwater is reliably prevented from spilling on the back surface of the outer wall plate.

Further, the outer wall plate 40 is pressed toward the back surface of the downward locking piece 13B by the cut-and-raised pieces 6 and 6 extending in the lateral direction functioning as urging means.
Attachment of the fastener 10 to the fastener 0 is stabilized. Further, since the cut-and-raised pieces 6, 6 are twisted so that the upper edge 6b is located at the front position with respect to the lower edge 6a, it is easy to insert the fastener 10 into the outer wall plate 40. further,
Since the upper edge and the lower edge of the substrate 11 are provided with the rising pieces 1 and 2 extending to the back surface side,
Air flow space Sc between 0 and the frame 61 side (see FIG. 2)
Is formed, it is possible to easily prevent the occurrence of dew condensation or the like on the back surface of the outer wall plate 40.

FIG. 4 is a perspective view showing another embodiment of the fastener according to the present invention. In this embodiment, one U-shaped cut-and-raised piece is provided at the center of the substrate 11, and the cut-and-raised piece is provided. The strip is first bent forward 90 degrees to form a horizontal strip 12.
A, and then bent obliquely upward to form an upward locking piece 1
3A, and then bent downward from the tip of the upward locking piece 13A to form a flat plate portion 14. Further, the lower end of the flat plate portion 14 is bent obliquely upward on the back side to further lower the downward locking piece. 13B. The other configuration is almost the same as that of the fastener 10 shown in FIG. Here, the downward locking piece 13B performs the same function as the downward locking piece 33B in the conventional fastener 30 shown in FIG.

The manner of use of this fastener is substantially the same as that shown in FIG. 1, and the rainwater flowing down the vertical gap S2 existing at the junction between the above-mentioned left and right outer wall plates. Wrapping around the back of the outer wallboard is likewise reliably avoided.

FIG. 5 is a perspective view showing still another embodiment of the fastener according to the present invention. The fastener 10 has a wide cut-out portion below the left and right cut-and-raised portions. As a result of the wide cutout, the cut-and-raised pieces 6 and 6 extending in the lateral direction functioning as the urging means of the fastener shown in FIG. 1 are not formed, but are formed by the cut-and-raised pieces of the left and right portions of the substrate 11. The lower portion 13B of the horizontal piece 12B and the downward locking piece 13B is formed by bending a portion near the lower end side of the downward locking piece 13B inward, thereby increasing the strength of the downward locking piece 13B. Stabilization of the attachment between the plate 40 and the fastening fitting 10 is ensured.

Further, the recessed portion 7 formed above the cut-and-raised portion at the center and directed toward the back surface is made longer in the lateral direction, thereby increasing the resistance of the entire fastener 10 to twisting and pressing force. . In this way, the nailing is actively performed at a position near the center of the fastener, so that the strength is greatly increased as compared with the conventional method of nailing mainly at the horizontal piece 3. This makes it possible to fix the fastener to the waistline or the like. As a result, the holding strength of the outer wall plate is greatly improved. In addition, as a result of the horizontally elongated shape, a plurality of (three in the figure) holes 8 can be formed therein, and the degree of freedom of fastening the fastening fitting 10 to the base material 61 is increased. . Also,
Thereby, it is not necessary to provide the hole 5 for nailing in the horizontal piece 3 at the tip, and processing is facilitated.

The manner of use of this fastener is also substantially the same as that shown in FIG. 1, and the rainwater flowing down the vertical gap S2 existing at the joint between the left and right outer wall plates described above. Wrapping around the back of the outer wallboard is likewise reliably avoided. In the fastening device according to the present invention, a fastening hole (for example, in the illustrated case, a hole provided in the inclined piece 2 and the horizontal piece 3 at the tip thereof) for attaching the fastening tool to the base material. The number and formation position of the holes 4, 5, and the holes 8) provided in the recessed portions 7 are arbitrary, and may be determined as appropriate according to the fastening strength required for the fastener. Further, it is optional to use which hole to nail.

[0025]

In the fastener according to the present invention, rainwater flowing down the vertical gap where the joint between the left and right outer wall plates exists flows out reliably to the front side at the fastener. For this reason, rainwater does not stay around the locking piece of the fastener, which tends to occur in the conventional fastener, and the rainwater is prevented from flowing around the back surface of the outer wall plate.
