Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a ventilation insulation board for a roof, which is used to constitute the roof base of a so-called air circulation type house.

(Problems to be solved by the prior art and the invention) In recent years, all rooms are surrounded by a ventilation space that communicates with each other, and by circulating cool air and warm air in the ventilation space,
BACKGROUND ART The development of air-circulating houses that are configured to improve the livability of the house and exhibit energy-saving effects is underway.

The ventilation insulation board used to form the roof base of such houses was developed in the 1980s.
What is disclosed in Publication No. 68207 has been proposed.
The board was intended to form a roof base similar to the roof base formed by installing roofing boards by pushing and fitting the boards between adjacent tarpaulins, but the following: I had a problem like this.

In other words, when using this board, when pushing and fitting it between adjacent talukis, if there is variation in the width between the talukis due to some warping or twisting of the talukis, it is difficult to fit the board tightly between the talukis. There was a problem in that it could not be fitted in the correct position, resulting in heat loss due to poor adhesion. In addition, it was necessary to lay a waterproof sheet material on the top surface of the roof base formed by fitting the board, as in the past.
There was room for improvement in terms of labor saving in roof construction.

The object of the present invention is to provide a roof ventilation insulation board that can solve these problems.

(Means for Solving the Problems) The ventilation insulation board for the roof (hereinafter referred to as the ventilation insulation board) 1 in the air circulation type house of the present invention is arranged between adjacent talli 2, 2 in an inclined state that matches the slope of the roof. The upper surface of the main body 3 of the board, which is a ventilation insulation board for a roof to be attached, is made of synthetic resin foam and has side vertical walls 9, 9 and a lower vertical wall 10 raised on both side edges and the lower edge of a rectangular plate-shaped substrate 7. A plate 6 constituting the roof base is attached to the top of the wall so as to cover the recess 26 formed by the vertical wall, thereby forming a vacant space 29 with an open upper end 27. Both side portions are fixed pieces 30, 30 that extend outward from the side walls 9, 9 and are placed on and fixed to the upper surfaces of the tarpaulins 2, 2, and on the upper surface of at least one side wall 9, A continuous groove 21 with open upper and lower ends is provided, and the outer part bordering on the groove 21 is a movable piece 2 that can be elastically deformed inward.
2, the outer surface 25 of the movable piece 22 is an inclined surface whose upper edge 25a is located slightly outward than the lower edge 25b, and a waterproof sheet material 31 is attached to the entire upper surface of the plate 6. It is characterized by:

(Function) However, in order to install the ventilation heat insulation board 1 between the adjacent tarpaulins 2, 2, as shown in FIGS. 2, 2, and the fixing pieces 30, 30 on both sides of the plate body 6 are placed and fixed on the upper surfaces of the tarpaulins 2, 2. At that time, even if there is a variation in the width between the tarpaulins due to some warping or twisting of the tarpaulin, such variation is absorbed by the appropriate inward elastic deformation of the movable piece portion 22. As a result, the board main body 3 is fitted tightly between the talukis 2, 2. And, due to the plate bodies 6... of the ventilation insulation boards 1... arranged in parallel in this way,
As shown in FIG. 6, a roofing surface portion 39 covered with a waterproof sheet material 31 is formed.

(Example) An example of the present invention will be described below based on the drawings.

In Figures 1 to 7, the ventilation insulation board 1 of the present invention
A plate body 6 is attached to the upper surface part 5 of the board main body 3, which is fitted between the adjacent tarukis 2 and 2 (see Figures 5 and 6).
This is the one that has been installed. The board main body 3 is entirely constructed using synthetic resin foam such as expanded polystyrene, and has side vertical walls 9, 9 on both longitudinal side edges and the lower end edge of the substrate 7, which is in the form of a rectangular plate that is long in the vertical direction.
And the lower standing wall 10 is raised, and the upper surfaces 11, 11 of the side standing walls 9, 9 and the upper surface 12 of the lower standing wall 10 are substantially flush with each other. In this embodiment, the upper surface of the upper end portion of the substrate 7 in the inclined direction is formed into an inclined surface 13 so that the thickness of the upper end portion becomes gradually thinner toward the upper end, and the central portion of the lower vertical wall 10 is formed into an inclined surface 13. The reinforcing ribs 15 are integrated with the substrate 7 and extend in the vertical direction, and the upper surface 16 of the ribs 15 is approximately the same as the upper surfaces 11, 11, 12 in the portion from the lower end to the lower edge 17 of the inclined surface 13. It is flush with the surface, and the inclined surface 13 is inclined parallel to the inclined surface 13. The lower standing wall 10 includes side standing walls 9, 9
The lower vertical wall 10 slightly protrudes downward from the lower ends 19, 19, and its lower surface is formed into an inclined surface 20 so that the thickness of the lower vertical wall 10 becomes gradually thinner toward the lower end.

Further, a continuous groove 21 whose upper and lower ends are open is provided on the upper surface of the side vertical walls 9, 9, and the outer part bordering on the groove 21 is a movable piece that can be elastically deformed inward. 22, and its upper surface 23 has an outer edge 23a located slightly lower than an inner edge 23b so that the movable piece 22 can be smoothly deformed without being hindered by the attached plate 6 as described later. (Fig. 3), and the outer surface 25 of the movable piece 22 is
The upper edge 25a of the outer surface 25 is an inclined surface located slightly outward than the lower edge 25b (third
figure). Note that even if the groove width of the split groove 21 varies between the talukis due to warping or twisting of the taluki, such variation is absorbed by the inward elastic deformation of the movable piece portion 22. It is set to the extent that

The plate body 6 includes side vertical walls 9, 9 and a lower vertical wall 1.
It is applied to the upper surface part 5 of the board main body 3 so as to be in contact with the upper surfaces 11, 12, 16 so as to cover the recess 26 formed by the board body 3, and is attached by means such as adhesive, As shown in FIGS. 1 and 7, a cavity 29 with an open upper end 27 is formed. The plate body 6 is made of plywood or the like having a strength sufficient to constitute a roof base by itself, and the upper and lower ends of the plate body 6 are connected to the tops of the side vertical walls 9 and 9, respectively. , is made to coincide with the lower edge, and its side parts are
Fixed pieces 30, 30 are placed and fixed on the upper surfaces of the tally plates 2, 2 by projecting outward from the side vertical walls 9, 9, and the amount of overhang of the fixed pieces 30, 30 is the width of the top surface of the tally plates 2. It is set to about half of that.

The waterproof sheet material 31 is made of a synthetic resin sheet with excellent waterproof properties such as nylon or polyester, and extends over the entire surface of the upper surface 32 of the plate 6 and overlaps two sides sandwiching one of the lower corners. It has an overhanging portion 33 and is attached by adhesive or other means.

However, in order to construct a roof using the ventilation insulation boards 1 according to this embodiment, first, the ventilation insulation boards 1 are sequentially attached between adjacent tarpaulins 2, 2, for example, from the eaves to the ridges. At that time, as shown in FIG. 7, the main body 3 of the board is pushed and fitted between the talukis 2, 2 so that the empty chamber 29 opens upwardly. Due to the appropriate inward elastic deformation, variations in the width between the talukis caused by warping or twisting of the talukis are absorbed, and as a result, the board main body 3 is fitted tightly between the talukis 2, 2. It will be.
In the fitted state, the fixing piece 30 placed on the upper surface of the diaphragm 2 is nailed and fixed to the diaphragm 2. As shown in FIG. 7, the ventilation insulation board (particularly designated as 1b) installed directly above the ventilation insulation board (particularly designated as 1a) is installed between the talcs so that the ends of the upper and lower plates 6, 6 are in contact with each other. At this time, the ends of the upper and lower side vertical walls are in contact with each other, and both inclined surfaces 13 and 20 face each other vertically with a ventilation gap 34 formed therebetween. In this manner, the ventilation insulation board 1 of the present invention is sequentially installed vertically, horizontally, and horizontally between the tarpaulins, and at this time, as shown in FIGS. By overlaying the protruding portion 33 on the waterproof sheet material 31 of the opposite edge (side edge 35 or upper edge 36) of the adjacent ventilation insulation board, the waterproof sheet material 31 is formed as shown in FIG. A raised surface portion 39 of the roofing material 37 is formed, which covers the roof material 37 and ensures watertightness at the joint portion of the plate bodies. If necessary, a release paper is pasted on the entire or part of the lower surface of the protruding portion 33 via an adhesive layer, and by peeling off the release paper, the protruding portion 33 is waterproofed at the opposite edge. It may also be adhesively fixed to a sheet material.

In addition, in the roof construction examples shown in Figures 6 and 7,
The lower end of the roof base board 6 located at the lowest end is made to coincide with the lower end of the lower standing wall 10. Furthermore, as the roof base board located at the lowest end, a roof base board configured similarly to that shown in FIG. 1 may be used, in which case,
For example, the protruding portion 34 (shown in FIG. 6) from the lower end 19 of the side wall 10 of the lower wall 10 is cut off, and the plate 6
The lower end of is in contact with the inside of the fascia plate 38.

Incidentally, the operation of the roof constructed in this way will be explained as follows, taking the winter season as an example. That is, if there is sunlight on the roof surface, the air in the empty room 29 is heated through the roof material 37 and the plate 6. The warmed air in the cavity 29 rises and is discharged from the ventilation gap 34 into the attic 40, and instead, the low-temperature air in the attic 40 flows into the cavity 29 from the ventilation gap 34. , the air will convect as shown by the arrows in FIG. 7, and heat will be stored in the building. Conversely, at night, the air within the cavity 29 is cooled and remains stationary within the cavity 29, forming an insulating roof.

FIG. 8 shows another embodiment of the ventilation insulation board 1 of the present invention, in which only one side vertical wall 9 is provided with a dividing groove 21. Also, waterproof sheet material 31
is attached only to the upper surface 32 of the plate 6. However, in order to construct a roof using the ventilation insulation board 1 according to this embodiment, it is necessary to use the ventilation insulation board 1.
are attached sequentially from top to bottom, left and right between the panels, and a waterproof tape made of synthetic resin or the like is pasted to the connecting parts of the plates to form a roofing surface covered with a waterproof sheet material, and the roofing material is A roof is constructed by covering the raised surface with roofing materials.

(Effect of idea) The present invention has the following excellent effects.

The roof underlayment board of the present invention has movable pieces on both sides, so when the main body of the board is pushed and fitted between adjacent talukis, the taluki may be warped or twisted to some extent. Even if there is variation in width, this variation is absorbed by appropriate inward elastic deformation of the movable piece. As a result, the main body of the board is tightly fitted between the talukis, and heat loss due to poor adhesion is prevented. Furthermore, since the main body of the board is made of synthetic resin foam, it itself has excellent heat insulation properties.

Due to the synergy of these factors, the ventilation insulation board of the present invention contributes to improving the performance of air circulation type buildings.

The ventilation insulation board of the present invention has a plate forming the roof base section attached to the upper surface of the main board, and both sides of the plate serve as fixed pieces, and a waterproof sheet material is attached to the upper surface of the board. As a result of the sticking structure, by sequentially attaching the ventilation insulation boards vertically and horizontally between the tarpaulins, a roofing surface portion covered with the waterproof sheet material can be formed. Therefore, by directly covering the roofing material such as tiles on the roofing surface, it is possible to construct a roof that exhibits an efficient ventilation and heat insulation effect.

As described above, when using the ventilation insulation board of the present invention, it is possible to not only omit the work of installing roofing boards, but also simplify the work of laying waterproof sheet materials, thereby saving labor in roof construction.
