Description

[Detailed description of the invention] [Industrial application field] The present invention is based on the invention, which is a sloped straight ridgeline formed by two adjacent roof surfaces of a square roof or a hipped roof. This invention relates to an improvement in a roof board for a downhill roof, which has a patch on the back side of the adjacent ends of the roof boards and prevents rain from leaking between the adjacent ends.

[Conventional technology]

Conventional spoil boards for descending ridges have a flat rear end, and are simply fitted to the end of the roof board, and are not fixed to the rafters near the descending ridge. .

In other words, for square roofs or hipped roofs using horizontal roof shingles, the roof surface on one side of the descending ridge is raised from bottom to top using a known method, and then the roof surface on the other side of the descending ridge is roofed in the same way. Construction procedures are being followed, including raising the roof. To connect the roof panels for the descending ridge, attach the shingle boards for the descending ridge to the ends of the roof panels, fix the roof panels to the rafters with hangers, and move them from bottom to top to one side of the descending ridge. After the entire roof surface is thatched, insert the end of the roof board of the next roof surface into each descending ridge board from the side, and insert the decorative cover into the decorative cover support part of the descending ridge board from below. This is done by fitting.

Therefore, after the entire roof surface on one side of the descending ridge has been roofed, all the scrap boards for the descending ridge were placed consecutively along the descending ridge when moving on to roofing work on the next roof surface. However, the waste boards for the downhill are not fixed to the rafters, but are only fixed to the ends of the roof boards that have been previously installed due to the frictional resistance at the parts where they are fitted.

As yet another method, a pair of gutters formed in an approximately C-shaped cross section are butted together and placed on either side of the ridge of the roof along the entire longitudinal length of the ridge, with the lower legs of both gutters being arranged along the flow of the roof, a cap being fitted over the upper leg piece over the entire length of the gutters, spanning the upper leg pieces of both gutters, one end of a tile being inserted between the legs of each gutter, both widthwise ends of the cap being folded downward to form a gutters, and the tip of the upper leg piece of the gutters being engaged between the both ends of the cap and the gutters (see, for example, Utility Model Publication No. 1983-52219).

[Problem that the invention attempts to solve]

In the case of the former conventional example mentioned above, the ridge roof scrapboard is in a free state with respect to the rafters and is simply fixed to the end of the roof board by frictional resistance at the fitting site. It easily moves due to slight vibrations during construction, contact with other objects, etc., and the position and orientation of the downhill scrapboard is inconsistent. The entire board for the descending ridge is bent into a chevron-shaped cross section with the middle part in the width direction as the ridgeline, so if there is a certain amount of deviation in the position or direction, it will cause the next roof surface (the roof on the other side of the descending ridge) surface)
When constructing the roof, it became impossible to insert the end of the roof board into the waste board for the descending ridge, and therefore, when inserting the end of the roof board, it was necessary to correct the position and orientation of the waste board for the descending ridge. .

By the way, as is well known, roof shingles are manufactured with high precision under strict quality control through factory processing. Since it is cut off at a 45 degree angle, there is usually considerable variation in the angle and straightness of the cut. For this reason, once
Even if the position and orientation of the roof shingle is set correctly, when the end (cut) of the next roof shingle is inserted into the shingle shingle, the angle and straightness of the end of the roof shingle will be incorrect. Due to the error, the attitude of the downhill scrapboard is likely to change.

Therefore, the above-mentioned correction of the position and orientation of the descending ridge scrapboard is actually a very troublesome work, and the number of descending ridge scrapboards to be used for one descending ridge is, It can reach 20 to 50 pieces, so
The above correction work has a large impact on construction efficiency as a whole.

In addition, in the descending ridge, the waste board for the descending ridge is provided over the entire length of the descending ridge with a part wrapped, and the decorative cover is also provided continuously over the entire length of the descending ridge. Even if there is a slight deviation in the orientation of the scrap board, the decorative cover will form a zigzag pattern, which is very noticeable and unsightly. In addition, incorrect installation of the roof deck scrap boards and decorative covers can cause rain leaks.

In addition, the latter proposal described in the above-mentioned prior art section, as shown in Figures 4a and b of the publication, involves abutting the shell pieces of the drainer 1 over the entire length in the longitudinal direction of the descending ridge of the roof. Since the structure is such that rainwater easily enters through this abutting portion, there is a drawback that an effective waterproofing function cannot be exhibited.

The object of the present invention is to provide a waste board for a downhill that can eliminate these conventional drawbacks, has a simple structure with a small number of parts, and has good construction efficiency.

(Means for solving the problem) A waste board for the descending ridge that is applied to the back side of the adjacent ends of the roof plates located adjacent to each other on both sides of the descending ridge, and whose middle part in the width direction is the ridge line. It has a lower plate portion bent into a chevron-shaped cross section, and decorative cover support portions provided on the left and right sides along the ridgeline on the lower plate portion, and the decorative cover support portion is attached to a base plate fixed to the lower plate portion. It consists of a letter-shaped first hardware and a U-shaped second hardware that is not fixed to the lower plate.
A pair of positioning protrusions having an L-shaped cross section are fixed to a rear position of the decorative cover support part,
A waterproof gasket with a length spanning both of the protrusions is attached to the protrusion, and a raised plate for draining is bent at a position rearward of the positioning protrusion of the lower plate. The structure is characterized in that a mounting piece for fixing the drop board to the rafters is bent and continuous from the upper end of the standing board for draining toward the rear.

[Effect]

According to the above-mentioned configuration, by fixing the attachment pieces to the rafters with nails, drill screws, etc., it is possible to fix the downhill scrap board to the rafters.

Even if the mounting piece has a hole for a nail or drill screw, a pair of positioning protrusions with an L-shaped cross section are fixed to the upper surface of the lower plate at a position rearward from the decorative cover support part. Since a waterproof gasket is attached to the projecting piece, the length of which spans both projecting pieces is pasted, so this positioning projecting piece and the waterproof gasket prevent further rainwater from entering the roof from both ends of the roof. In order to effectively prevent infiltration, a raised board for draining is bent at a position rearward of the positioning protrusion of the lower board, and this waste board is folded backward from the rear end of the roof board.
A dead space is formed between the drainer and the standing plate, and this dead space functions as a rainwater receiving area in the unlikely event that rainwater enters.
No water leaks from the holes of the nails or drill screws.

Moreover, one roof board is covered by fitting the end of one roof board into the U-shaped first hardware fixed to the lower board part, and then the end part of the other roof board is fitted with the lower board part. A pair of roof plates formed with a U-shaped cross section by placing the other roof plate on the lower plate part of the waste plate while fitting a U-shaped second metal fitting that is not fixed to the roof plate. Unlike the conventional structure in which both members are fixed to the roof ridge and the ends of both roof panels are fitted into this, the workability of both roof panels can be significantly improved.

The number of parts is small because the mounting pieces are integrally bent and connected to the scrap board for the downhill.

[Effect of idea]

Since the present invention has the above-described configuration, it has the following effects.

(1) Even if there is a hole in the mounting piece, there is a standing plate for draining in front of it, so there is no risk of water leaking from the hole, and therefore the mounting piece can be fixed to the rafter with nails, drill screws, etc. By doing this, it is possible to fix the downhill scrapboard to the rafters.

Therefore, when roofing from the bottom to the top, or when roofing the other side of the roof, the roof shingles for the roof will not move unexpectedly, and the ends of the roof shingles processed on site will not move. Even if there is an error in the angle or linearity, the position and orientation of the downhill scrapboard can be maintained constant without being affected by this, greatly improving construction efficiency.

In addition, since the position and orientation of the downhill scrapboards are correct, the decorative covers are lined up in a straight line along the entire length of the downhill, and the decorative covers do not form a zigzag pattern, resulting in a beautiful appearance and high waterproof performance. is ensured.

(2) Since the mounting pieces are integrally bent and connected to the downhill scrapboard, the number of parts is small, there is no risk of losing the mounting pieces, and material management is easy.

(3) In particular, the present invention can effectively prevent rainwater from entering from both ends of the roof board into the shingle by the pair of positioning protrusions having an L-shaped cross section and the waterproof packing.

Furthermore, the dead space formed behind the roof board of the waste board serves as a space for receiving rainwater that may have entered the roof board, effectively preventing rainwater from entering the back of the roof board.

Therefore, compared to the conventional technology mentioned at the beginning,
Its waterproof effect is extremely excellent, and it has the advantage of being able to more effectively exhibit the waterproof performance described in (1) above.

(4) Furthermore, the present invention provides that the decorative cover support section
Since it is composed of a U-shaped first hardware fixed to the lower plate and a U-shaped second hardware not fixed to the lower plate, the U-shaped second hardware is attached to the bottom in advance. The disadvantage of workability when it is fixed to the board is that it involves lifting a so-called long roof board and inserting the ends into the U-shaped hardware that is already fixed in place, bending at the waist. There is no troublesome work, and the work is easy, as the second metal fittings are fitted to the edge of the other roof board in advance, and then the roof board is inserted into the waste board.
