Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to horizontal reed exterior materials used as roofing materials for newly constructed buildings, roof repairs of existing buildings, and other exterior materials covering external walls. As shown in Figure 1, there are retaining parts (1a) on the eaves and ridge sides, respectively.

(1b) Stepped roofing material (1). As shown in Fig. 2, this stepped roofing material (1) has a retaining part (1b) of the roofing material (1) on the ridge side fixed to the shedding board (2). ) to the retaining part (1) of the roofing material (1) on the eaves side
By engaging a), the roofing is sequentially applied toward the ridge side.

Such a stepped roofing material (1) may have strength problems such as being unable to withstand the weight of the roofing material, which may be placed on top of the roofing material during construction.

In order to solve these problems, a horizontal reed exterior material that combines a hanger (3) and a roofing material (4) as shown in FIG. 6 has been prototyped and is being studied. The end of this hanger (3) has a substantially inverted triangular shape, and one end extends inward almost horizontally, then makes a U-turn downwards and folds back.
), the other end is gently extended outward, the end is made a U-turn downwards, and then folded back to form a retaining/fixing part <3b). The roofing material (4) has one end tied with a hanger (
3), the other end is inserted into the engaging/fixing part (3b), and is fixed onto the roofing board (2) with a nail (5).

Although the exterior material constructed in this manner has greater strength than that shown in FIG. 1, it has the following problems.

As shown in Figure 3, simply inserting the roofing material (4) into the retaining part (6a) at the tip of the hanger (3) will not allow rainwater to leak into the triangular bag-shaped part (6c) of the hanger (3). Cracks, etc. get in there. For this reason, it is possible to provide a drainage hole in a part of the triangular bag-shaped part (6c), but the drainage hole is located at the top (in use, at the bottom).
If it is not, it will not be possible to drain the water completely. Also, if there is a hole at the top, it is fine if it is not long after construction, but as time passes, dust etc. may accumulate and block the drain hole.

If water is not drained completely, the hanger will quickly corrode and lose its economic efficiency. In addition, in cold regions, if moisture enters in the winter, it will repeatedly freeze and thaw, causing phenomena such as gas leaks.

In addition, the other end of the hanger (3) is gently extended as a retaining/fixing part, but this shape requires a large amount of material for the hanger (3), and the effective size of the roofing material also increases. becomes smaller, resulting in poor economic efficiency.

The present invention was devised in view of this situation, and provides a horizontal reed exterior material that is excellent in rain protection, strength, economic efficiency, and safety.

Next, the present invention will be explained based on examples thereof.

FIG. 4 is a side view of a hanger according to an embodiment of the present invention.

This hanger chain has a triangular bag section at its tip, and one end of the bag extends almost horizontally inward, then makes a U-turn downwards and folds back to form a retaining section (10a). . On the other hand, the other end of the triangular bag portion extends slightly outward, is bent downward, and is further bent outward, so that the cross section has a tl ladder shape. Then, the end portion is extended outward and folded back downward in an inverted S-shape, leaving a nailing type dimension, to form a fixed fixing portion (10b).

FIGS. 5(a) and 5(b) are side views of a roofing material according to an embodiment of the present invention, respectively. The roofing material α in the same figure (&) has one end bent downward into a U-shape, and the end further made a U-turn to form an almost S-shaped retaining part (11 m).
Then, from the midway extending from the S-shaped top of the retaining part (11a), it is further extended slightly downward with a smooth inclination, and the position where the square apex of the hanger comes from the end. Fold the engaging part (1) upward slightly to return to its original position.
A semicircular protruding water return rib (11e) is provided between the bent position and the end of the retaining portion (11b,) where the retaining portion (1b) is formed. In the roofing material 01) shown in FIG. 6(b), the angle of the sloped part at the center is made large, the area of the sloped part is made small, and the area of the horizontal part is increased. Each of these roofing materials CIL (11A) is constructed so that its height matches the center height H of the retaining portions (10a) and (10b) of the hanger a1.

Next, the construction procedure will be explained based on FIGS. 6 to 8.

First, fasten the flat part of the tie-down/fixing part (10b) of the hanger member from above to the baseboard (2) or rafters with nails (5) or screws (Figure 6). Next, the roofing material←9

(
Figure 7). Insert the engaging part (11b) of the roofing material αη into the upper part of the S-shaped part of the retaining/fixing part (10b) of the hanger θO, and connect the roofing material (11) and the hanger (1). At one time, the roofing boards (2) are fixed to the base material such as oak or rafters with nails (5) or screws (Figures 8 and 6).

Repeat the above steps from the eaves to the ridge to cover the roof.

In addition, although the above-mentioned example is an example of the case where it is used as a roofing material, the member according to the present invention can also be used as an exterior material, and in that case, proceed from the foundation side upwards.

Here, the results of the strength test of the above embodiment (the configuration shown in FIG. 8) are shown in comparison with the configuration shown in FIG. 5 as follows.

Table 1 (Negative pressure uniformly distributed load test) The test results shown in Table 1 are for the roofing material when a uniformly distributed load is applied to the roofing material from the direction of the roof board in the configuration shown in Figures 6 and 8. It shows the bending rigidity of the central part. This deflection rigidity refers to the load per unit area when the central part of the roofing material is deflected by 1 (m) under a load within the elastic limit.

Moreover, the above test results indicate the average value of several test materials.

As is clear from the above description, the following useful effects are obtained according to the present invention.

(a) The cross-sectional shape of the hanger is a combination of a triangle and a trapezoid, which improves the strength17.

(b) Since the strength is improved, the width of the hanger can be made smaller and the material used for the hanger can be saved.

Since the width of the hanger is smaller, the effective width of the roofing material can be increased, and the amount of material used per unit area can be saved, which is economical.

(b) Since the tip of the roofing material on the eaves side (retention part) wraps over the hanger, rainwater does not get inside the hanger. Therefore, there is no corrosion from inside the hanger due to rust or freezing in winter, and the service life can be extended.

In addition, since there is no need to drill holes in the hanger, the number of processing steps can be reduced and it can be manufactured economically.

(E) When the engaging part of the roofing material is inserted into the engaging part of the hanger, the lifting of the roofing material due to the suction force of the wind is suppressed to a smaller extent than when the roofing material made of a flat plate is directly inserted (see Figure 6). has been confirmed by experiment. Therefore, safety against external forces is improved.
