(Effects of the Invention) As explained above, in the dry building of the present invention, a gap is formed between the plurality of threaded rods installed on the ridgepole and the roof board at the locations where they pass through the ridge of the roof, The top plate of the ridge stand placed on the ridge part and the top plate of multiple ridge center members placed in a layered manner on the top of the ridge stand through the main body part are required outside the through holes of the draw rod. Ventilation holes are provided according to the requirements, and it is attached to a part of the uppermost ridge member 01 through a naso I screwed into each threaded rod and fixed to the ridge part together with the ridge stand and the ridge member. The same hole as that of the center member is provided in the cover support part H to be attached, and the uppermost part is provided with the uppermost part through the cover member and spacer which cover the negative part of this cover support member. A crown tile is provided to which the cover support part (A) is fixed, and a narrow passage is formed between the cover support part (A) and the cover member to prevent the air from the ridge part rising from the ventilation holes of the ridge stand and each wire core part 4A from passing through. The baffle plate has a large number of air holes through which the air that has passed through this baffle plate part flows out from the cover member, and the air that flows out from these air holes exits into the inside of the crown tile. At this time, by providing a cover support part that extends in the direction of the crown tile and narrows the passage, the air in the ridge passes through the baffle plate part, which is a narrow passage, and the F part of the cover support part, and flows into the crown tile. After that, it flows out of the dry building through the gap at the bottom of the crown tile formed by sliding, so the ridge can be constantly ventilated.Also, during typhoons, etc., the gap at the bottom of the crown tile flows out. When wind and rain enters the ridge, the cover support member prevents the wind and rain from entering the cover member, and the baffle plate prevents the wind and rain from entering the ridge member. This can prevent corrosion of wood in the ridge and ceiling, making the house last longer.

In addition, even in a dry type building in which an upper ridge center member is attached to the bottom of the second ridge member, and a cup member is provided to cover the upper part of the upper ridge center member, a cup communicating with the ridge member is installed. Since the inside of the member and the outside air side are communicated via a spacer fixed to the lower part of the wing surface of the cover member, the ridge can be ventilated, and the baffle plate provided on one member allows ventilation of the ridge. can prevent rainwater from entering.

Further, by providing grooves into which the legs of the cover member fit in the spacer support portion of the spacer support member, the cover portion H can be easily attached to the spacer support member, and the time for attaching the cover portion H can be shortened.

Furthermore, when fixing the spacer to the roof tile, it is possible to use wood screws, etc. by inserting it into the spacer support member through the engagement groove, or by clamping it on the inside of the roof tile with a clamping piece. The work time can be shortened compared to fixing the spacer to the roof tile.
