Description

[Detailed Description of the Invention] <Industrial Application Fields> The present invention relates to a connecting waste board for horizontal roofing materials that is attached to the connecting portion of horizontal roofing materials that constitute the roof surface of a building. It is easy to use, can be used in any connection part, and is designed to reliably prevent rainwater from entering through the connection part.

<Prior Art> As is well known, waste boards are attached to the joints of horizontal roofing materials forming the roof surface of buildings to prevent rainwater from entering. For example, there is a type of waste board described in Japanese Utility Model Publication No. 57-36741, and this waste board has receiving grooves formed on the left and right sides that open laterally as inserting parts for the edges of the roofing materials arranged on the left and right. A supporting portion is provided in the longitudinal direction at approximately the center in the width direction, and a plurality of shallow groove-shaped guide portions are formed on the left and right sides of the supporting portion parallel to the supporting portion and allowing rainwater to flow down in the direction of inclination,
A bent piece is formed at the front end to fit into the engaging portion of the roofing material.

<Problems to be Solved by the Invention> However, since the above-mentioned conventional scrap board is attached to the edge of the roofing material from the lateral direction of the receiving groove, it cannot be used in connection parts where there is no room for lateral movement. In addition, since the engagement between the folded piece and the engagement part formed on the roofing material is shallow, it is easy to come off, and the roofing material may be rolled up by strong winds, or the tip of the folded piece may not fit into the engagement part formed on the rear end of the roofing material. If the roof is located at the rear of the roof, rainwater may penetrate through the bent pieces and seep into the attic.

(Means for Solving the Problems) The present invention was proposed in view of the above, and consists of horizontally covering roofing materials having a locking portion at the front end and an engaging portion at the rear end. In a roof that is connected by a scrap board and the engaging part of the roofing material located at the upper level is engaged with the engaging part of the roofing material located at the lower level. The vertical length of one half is longer than the height of the rear opening of the locking part, and the vertical length of the other half is the height of the rear opening of the locking part. This is a shorter version.

<Function> The vertical length of the bent piece provided at the front end of the waste board is made so that one half is longer than the height of the rear opening of the locking part of the roofing material, and the other half is shorter than the height of the rear opening. Therefore, the bent piece of one side of the waste board can be firmly fitted into the locking part of one of the left and right roofing materials, and the other roofing material can be attached from the front of the waste board to shorten the length. The other half of the folded piece can be housed within the movable part of the roofing material.

b, and a second mountain portion 3C formed by bending the tip of the first mountain portion 3b, and an engagement space 4 is formed between the base 3a and the hill portions 3b, 3c and the upper surface of the roofing material 1. Form.

On the other hand, the engaging portion 3 is located at the front end along the longitudinal direction of the roofing material l.
A folded locking portion 5 is formed in a bent manner on the lower surface side opposite to the above. The locking portion 5 consists of a substantially vertical bent piece 5a facing downward from the front end of the roof material 1, and a folded piece 5b extending rearward from the lower end of the bent piece 5a. The protrusion 5c is provided. Therefore, the locking portion 5 has an inner height H.
A rear opening 6 is formed.

To roof the roofing material 1 made as described above, the roofing material 1 is arranged horizontally, each edge 2.2 is butted against each other, and a scrap board 7 is placed at the connecting part of the roofing material 1.1 formed by the butting. At the same time, the locking part 5 at the front end of the roofing material 1 located at the upper stage is engaged with the engaging part 3 at the rear end of the roofing material 1 located at the lower stage.

Therefore, the waste board 7 according to the present invention is provided with a downwardly bent piece 8 that fits into the locking part 5 of the roofing material 1 at the front end, and the longitudinal length h1 of one half of the bent piece 8 is The vertical length h2 of the other half is shorter than the height H of the rear opening 6 of the locking part 5 of the roof material 1.

Further, in the embodiment shown in FIGS. 1 to 3, a support portion 9 is provided in the depth direction approximately at the center of the waste board 7 in the width direction. Support part 9
These are for configuring left and right receiving grooves 1O110 that open in opposing lateral directions into which the edge 2.2 of the roofing material 1 can be inserted. Further, the waste plate 7 is provided with a plurality of shallow groove-shaped guide portions 11 parallel to the support portion 9. This groove-shaped guide portion 11
It is composed of a plurality of folded lines 12a, 12b, and f2c formed in the same direction. Note that the support part 9 in the embodiment of the drawings is clamped by the folding strips 12a, 12a located at the innermost side of the folding strips 12 appropriately provided on the scrap board 7, but other fastening strips 12a and 12a In addition, the support part 9 does not need to be provided over the entire depth of the waste board 7, and may be provided at an appropriate length at a key point. , a front opening 13 on the upper surface side of the rear end of the waste plate 7.
A receiving portion 14 is provided.

In order to construct the roof of a building with the scrap board 7 and the roofing material 1 formed as described above, the edge 2 of the roofing material l is
The bent piece 8 is inserted into the receiving groove 10 on the side having the long vertically elongated h1. At this time, if a foam material 15 having heat insulating and sound damping properties is attached to the lower surface of the roofing material 1, the hook part z6 provided at the entrance of the receiving groove 10 will bite into the foam material 15 and the roofing material 1 It becomes difficult to pull out. Then, a half portion of the folded piece 8 of the waste board 7 having a long longitudinal length h1 is fitted into the locking part 5 of the roofing material 1, so that the roofing material 1 and the waste board 7 are joined together. Then, the locking part 5 of the roofing material 1 with the scrap board 7 attached thereto is engaged with the engaging part 3 at the rear end of the roofing material 1 located at the lower stage. That is, in the engagement space 4 of the engagement part 3 of the roofing material 1, the roofing material l located at the upper stage is
The folded piece 5b of the locking portion 5 is inserted. Then,
The other roofing material l that connects left and right is attached to the other half of the folded piece 8 of the waste board 7, and the vertically long h2 of the other half of the bent piece 8 of the waste board 7 is the locking part of the roofing material l. Since the roof material 1 is formed shorter than the height 5, the roof material 1 can be easily installed from the front. That is, if the roofing material 1 is slid from the front to the rear while inserting the edge 2 of the roofing material 1 into the receiving groove lO of the support part 9 of the waste board 7, the inside of the locking part 5 at the front end of the roofing material 1 can be slid. One hand of the folded piece 8 of the waste board 7 is inserted, and the engaging part 3 at the rear end of the roof material 1 engages with the receiving part 14 at the rear end of the waste board 7. Therefore, it is possible to connect the roofing material 1 without moving it laterally, and it can also be used for descending ridges or rising parts of roofs where there is no room to move the roofing material 1 laterally. Incidentally, if necessary, a cover material (not shown) is applied to the upper surface of the support portion 9.

As described above, when the waste board 7 is interposed between the connecting parts of the left and right adjacent roofing materials 1 and 2, rainwater flowing in from the connecting part of the roofing materials 1 and 1 flows down the top surface of the waste board 7. Since the rainwater falls onto the upper surface of the roofing material l located at the lower level, rainwater can be discharged to the outside of the roof. At this time, the vertical length h1 of one half of the bent piece 8 is formed to be longer than the height H of the rear opening 6 of the locking part 5 of the roof material 1, and the bent piece 8 and the rear opening 6 are strengthened. Since the bending piece 8 does not come off from the roofing material 1, rainwater can be reliably guided to the upper surface of the lower roofing material 1. Further, even if rainwater flows laterally and exceeds the first groove-shaped guide portion 11a, the second and third groove-shaped guide portions 11b and llc, which are provided in plurality, prevent further infiltration. Therefore, all the rainwater that enters from the connecting portion of the roofing material 1 can be discharged to the upper surface of the roofing material 1 located at the lower level, and the rainwater does not seep into the attic.

As described above, according to the present invention, roofing materials 1.
1 can be attached to the scrap board 7 from the front, which not only greatly simplifies construction, but also allows it to be used in areas that cannot be moved laterally, such as on rising parts of roofs, descending ridges, valleys, etc. Can be done.

The first upright surface 17a of the stepped portion 17 and the bent piece 5a of the locking portion 5 are neatly aligned flush with each other.

On the other hand, for the roofing material 1.1 adjacent to the left and right, the same waste boards 7 as in the embodiments shown in FIGS. 1 to 3 described above are used. That is, a rear opening 6 is provided in the locking portion 5 of one roof material l.
The roofing material l and the waste board 7 are joined by fitting one half of the bent piece 8 of the waste board 7, which has a vertical length h1 longer than the height H of the roof material l. Next, other roofing material l to be connected to the left and right is attached from the front to the other half of the bent piece 8, which has a vertical length h2 shorter than the height H of the rear opening 6 of the locking part 5, and is connected. do.

Therefore, according to the embodiment described above, not only can roofing be done without moving the roofing material l laterally, but also
In the roof thatched as described above, even if rainwater due to wind and rain rises on the roofing material 1 against the slope from the eaves side toward the ridge, the first upright surface 17 of the stepped portion 17 of each roofing material
A functions as a water return and prevents rainwater from rising. Therefore, it is possible to prevent a large amount of rainwater from spraying or accumulating at the connecting part between the locking part 5 and the engaging part 3, and it is possible to prevent rainwater from flowing from the connecting part of the vertically adjacent roofing materials 1 and 1. Infiltration can be effectively prevented. Furthermore, even if the connecting part between the locking part 5 and the engaging part 3 gets wet, the receiving part 3e is formed in the shape of a mountain at the end of the engaging part 3, thereby blocking the intrusion of rainwater due to capillary phenomenon. Furthermore, if the receiving portion 3e formed in the engaging portion 3 is formed into a plurality of mountain shapes, the effect of blocking rainwater will be further enhanced. In addition, roofing material 1
