Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a ridge structure for a building, and more particularly to a ridge structure for a building using roof board units with voids formed therein.

<Prior art> As is well known, in the ridge, which is the highest part of the roof where both the left and right roof surfaces that slope in a mountain shape meet the groove, the joint of the upper edge of the inner roof plate located at the upper end of the slope A ridge cover is placed along the ridge direction to prevent rainwater from seeping in. In addition, a base material made of wood wool cement board, hard foam urethane material, felt material, etc. is laid on the bottom side of the roof board to enhance soundproofing and heat insulation effects.

<Problems to be Solved by the Invention> However, in a roof on which a conventional base material is laid, a space is created between the roof board and the base material.

Air convection occurs within this space, and heat exchange via the air occurs between the outdoor side and the indoor side, impairing the heating and cooling effect on the indoor side.

Therefore, it may be possible to lay the base material twice,
Simply laying a double layer of base material not only does not allow the air in the gap to communicate with the outside air, but also doubles the effort required for two installations, prolonging the construction period and increasing material costs.

Means for Solving the Problems> The present invention has been proposed in view of the above, and consists of laying a base material on the upper surface of the rafters arranged in parallel along the slope of the roof surface formed in a mountain shape, and In a ridge where a roof plate is laid on the top surface of the material and a ridge cover is attached to the joint part of the inner roof plate located at the upper end of the slope, the E sub-base material has multiple spacers between the upper and lower substrates. Multiple voids were formed by intervening! ? The upper edge of the lower substrate of the roof board unit, which is located at the sloping end of the inner roof surface, is brought into contact with the upper edge of the bottom board along the ridge direction, and the above-mentioned gap is opened at the ridge part. be.

(Example) Below, the present invention will be described with reference to the embodiments shown in the drawings. First, the shedding board unit l used in the present invention includes, for example, a lower board 2 located on the ceiling side and a north board 3 located on the roof board side. A plurality of spacers 4 are interposed between them to form a plurality of gaps 5, and the lower substrate 2 and the upper substrate 3 are shifted by η in one diagonal direction. The outer edges of the substrates 2 and 3 extend or rearward of the outer edges of the other opposing substrate.Specifically, the length f direction of the rectangular lower substrate 2 made of plywood or the like is used. A ml spacer 4I is attached along one outer edge 6 of the sample.

This first spacer 41 covers approximately half of the width of the lower substrate 2.
It is made to protrude from one long side, and one outer edge 6 of the L-leg lower substrate 2 is the female long side 6a. 1- On the L surface of the lower substrate 2, a plurality of spacers 4 are arranged in parallel at appropriate intervals, approximately in a row, with the first spacer 4I as a reference, and the n-th spacer 41, That is, in the illustrated embodiment, the fifth spacer 45 and the outer edge 6 of the lower substrate 2 in the other hand direction
The distance between the spacers 4 is approximately equal to the distance between the spacers 4, in other words, the spacer 45 of the fifth Wi[1 is provided at a position t set back inward from the other long side of the lower substrate 2 by the distance of the spacer 4, The other outer edge 6 of the lower substrate 2 is defined as a male long side 6b.

Further, the length of each of the spacers 4 is made approximately equal to the length of the lower substrate 2 in the pitching force direction, and the top end and lower end of the spacer 4 are connected to the outer edge 6 of the lower substrate 2 in the direction of short hairs, that is, the length of the lower substrate 2 in the pitching force direction. Align it to the sides.

Then, on the upper surface of a plurality of spacers 4 arranged in parallel on the lower substrate 2, an upper substrate 3 of the same size made of plywood or the like is fixed to the upper surface of a plurality of spacers 4 arranged in parallel on the lower substrate 2, so that a plurality of spacers 4 extending in the direction of the pitcher's force are fixed. A void 5 is formed.

At this time, the upper substrate 3 is shifted from the L-leg lower substrate 2 in a diagonal direction and fixed. That is, one outer edge 7 of the upper substrate 3 is extended from the female long side 6a of the lower substrate 2 by the distance of the spacer 4, and the other outer edge 7 is placed about half on the fifth spacer 45. Thus, the upper substrate 3 is also formed with a male long side 7a and a female long side 7b. Further, the upper outer edge 7 in the short hair direction of the upper substrate 3 is set back by an appropriate width from the corresponding outer edge 6 of the lower substrate 2, and the lower outer edge 7 in the lateral direction is moved back from the corresponding outer edge 6 of the lower substrate 2. An eleventh connecting portion 8 is formed above and a second connecting portion 9 is formed below.

In addition, when there is a temperature difference between the outside of the lower substrate 2 and the outside of the upper substrate 3, the convection d of the void 5 is determined by the convection caused by turbulence, eddies, etc. of the air inside the air based on the temperature difference. It is preferable to set the thickness to about 5 to 15 mm so that no cracking occurs.6 If the roofing board unit 1 as described in 2 is produced in a factory in an integrated manner, it is possible to provide the roofing board unit 1 at a low cost.

On the other hand, at the construction site, elongated eaves hardware 12 is fitted in series along the needle direction to the inclined lower ends of the plurality of rafters 11 that are properly attached to the main building 10 at appropriate intervals.

Then, on the upper surface of each of the rafters 11, sheathing board units l are laid as a base material without any gaps in the slope direction and row direction of the roof 6, and each gap 5 of the sheathing board units l adjacent in the slope direction is
A plurality of communication passages 5' are formed in the inclination direction of the roof so that the five eaves and the ridge part communicate with each other in the inclination direction. At this time, in the girder direction, the male long side 6a and the female long side 6b of the lower substrate 2 of the laterally adjacent shedding board unit l fit together, and the female long side 7b of the upper substrate 3 is fitted. and the male long side 7a fit together, and in the inclination direction, the first connection part 8 and the second connection part 9 of the vertically adjacent roof board units 1.1
Since they fit together, positioning is easy and there is no gap.

Then, the first connecting portions 8 of the sheathing board units 1, 1 located at the sloped upper ends of both sides of the roof are butted against each other.

That is, the upper edge 2' of the lower substrate 2 is brought into contact with the groove at one ridge portion. At this time, since the upper edge 3' of the upper substrate 3 is set back from the upper edge 2' of the lower substrate 2, each communication passage 5' opens upward at the ridge portion.

In addition, the lower edge of the roofing board 22) l located at the lower end of the slope where the second connecting portion 9 is cut off is placed on the upper surface of the eaves hardware 12. In this way, even if rain leaks from the roof board onto the top surface of the roof board unit 1, it will flow down the top surface of the upper substrate 3 toward the eaves.

It is expanded in the longitudinal direction by the eaves hardware 12 and discharged laterally. Even if rainwater leaks from the joint of the upper substrate 3, the leaked rainwater will fall onto the upper surface of the lower substrate 2 through the communication path 5' (gap 5), and the leaked rainwater will fall onto the upper surface of the lower substrate 2 through the communication path 5' (gap 5), and the leaked rainwater will fall onto the upper surface of the lower substrate 2 through the communication path 5' (gap 5), and the leaked rainwater will fall onto the upper surface of the lower substrate 2 through the communication path 5' (gap 5). It flows through the passage 5' onto the upper surface of the eave hardware 12, flows laterally through the eave hardware 12, and is discharged. Therefore, rainwater does not seep into the ceiling, improving the rainwater effect.

After laying the roof board unit 1 on the rafters ll, the roof board 1
However, in the illustrated embodiment, a roofing 14 is interposed between the roofing board 13 and the shedding board unit 1, and the roofing board 13 is laid on the roofing 14. roof board 1
3 is installed by locking the downward locking portion 15 of the roof board 13 located one eave ahead with the locking piece 12a of the eaves hardware 12.

The upward engaging portion 16 is attached to the rafter 1 using a hanger or the like (not shown).
A roof board 13 that is attached to the roof panel 1 and located on the side of the eaves where it is attached.
The upward engaging part 16 engages the downward engaging part 15 of the roof board 13 adjacent to the line side, and one edge 13 of the roof board 13 located in one part of the roof is successively raised toward the ridge and is attached to the ridgepole 17.
It stops at . A ridge cover 19 having a space 18 inside is attached to the upper part of the second ridgepole 17.

The ridge cover 19 is a long material bent into a mountain shape, and has a downward hanging piece 20 in the longitudinal direction.
A folding piece 21 is provided by folding the lower end of 0 inward and upward. A space is provided between the lower end of the hanging piece 20 and the upper surface of the roof board 13, and a communication path 5' of the roof board unit 1 is provided.
Allows air to flow out to the outside.

In a roof where the roof board unit 1 as described above is installed as a base material, the air gap 5 formed in each roof board unit 1 is
communicate with each other in the inclination direction of the roof to form a plurality of communication passages 5', and each communication passage 5' opens above the lower substrate 2 at the ridge portion, so that when passing through each communication passage 5', Air can flow out to the outside. Even if there is a large temperature difference between the outside of the upper substrate 3 and the outside of the lower substrate 2, the width d of the gap 5 between the upper substrate 3 and the lower substrate 2 can be formed to such an extent that convection does not occur. Therefore, the air in the gap 5 does not convect and heat exchange does not occur, improving the heat insulation effect and improving the soundproofing effect.

In addition, if the communication path 5' of each roof board unit l is made obstructable within the ridge cover 19 of the ridge, the air flow can be adjusted as necessary, and heat insulation and soundproofing can also be controlled. It is.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be carried out as appropriate unless the configuration described in the claims is changed.
