[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof flat structure.

[0002]

2. Description of the Related Art FIG. 4 is an exploded view of a flat structure of a roof disclosed in Japanese Patent Publication No. 7-84783. As represented by the example in this figure, the conventional flat ridge structure has a ridge ventilation opening 101 along the longitudinal direction of the flat ridge with respect to a roof frame assembled using rafters 100 and the like.
The base plate 102 is attached so as to form a roof sheet, a tarpaulin (not shown) is laid on the upper surface of the base plate 102, and the roofing material 104 is roofed. The ventilation ridge member 105 (so-called ventilation passage forming member) is placed so as to extend over the upper portion, and the upper portion of the ventilation ridge member 105 is covered with an umbrella-shaped ridge wrapping material 106. It was

The above-mentioned ventilation ridge member 105 is designed so that its cross-sectional shape has a quadratic corrugation, and a bulging chevron portion 110 protruding at the center and a gate-shaped portion 111 protruding on both sides thereof are formed. Have And these bulging chevron parts 11
The inclined bottom portion 112 connecting the 0 and the gate-shaped portion 111 and the inclined bottom portions 113 provided on both outer sides of the gate-shaped portion 111 are used as fixing plates for the roof material 104. Also, the bulging chevron portion 11
The rising pieces 110a of 0 and the rising pieces 111a of the gate-shaped part 111 have different heights, and the ventilation port 11
5, 116 are formed.

For this reason, the ventilation passages 115 and 116 are formed between the roof material 104 and the ridge wrapping material 106 on both sides of the ridge ventilation opening 101 to form ventilation passages along the roof flow direction. Is. Such a ventilation ridge member 105 is formed into a predetermined cross-sectional shape by pressing or extruding after forming ventilation openings 115 and 116 in a necessary portion of a flat plate material by punching or the like. It is usually produced.

[0005]

As described above, in the conventional flat ridge structure, it is necessary to form many ventilation openings 115 and 116 in the ventilation ridge member 105 used as the ventilation passage forming member. So these vents 115,
It was a material loss corresponding to 116.
In addition, the ventilation openings 115 and 116 in this case are generally formed as long holes (not shown) along the longitudinal direction of the flat ridge, but the ventilation openings 115 and 115 are adjacent to each other, and Naturally, the space between the adjoining 116 and the ventilation port 116 could not be opened, and the opening area as a ventilation passage could not be effectively utilized.

On the other hand, since this type of ventilation ridge member 105 is connected to the ridge wrapping material 106, it is necessary to have a sufficient thickness in terms of strength. Of course, this thickness is necessary for the ventilation ridge member 105 as a whole. As a result, material costs have risen sharply, and handling, such as transportation, may be time consuming due to the weight. The present invention is
A roof that has been made in view of the above circumstances and that can reduce the material cost, facilitate handling and construction of flat ridges, and effectively utilize the opening area as a ventilation passage. It is intended to provide a flat building structure of.

[0007]

In order to achieve the above object, the present invention takes the following means. That is, the flat roof structure of the roof according to the present invention covers the ridge ventilation opening formed along the longitudinal direction of the flat roof ridge with the umbrella-shaped wrapping material over the entire length. Thus, the ventilation passages are formed between the roof material on both sides of the ridge ventilation opening and the wrapping material above and below the roof wrapping direction. And this structure has a 1st partition material and a 2nd partition material, and connects these 1st partition material and a 2nd partition material along the roof flow direction in the longitudinal direction several places of a flat ridge part. It has a connecting member for.

The first partition member is provided on the higher side in the roof flow direction in the ventilation passage, and is hung from the back surface side of the ridge wrapping material in a direction that blocks the roof flow direction. In addition, the first partition member is formed long along the longitudinal direction of the flat ridge. The second partition member is provided so as to stand on the lower side of the roof flow direction in the ventilation passage and in a direction that blocks the roof flow direction from the upper surface side of the roof material. Further, the second partition member is also formed long along the longitudinal direction of the flat ridge portion. Therefore, the first partition member and the second partition member are connected to each other by the connecting member so that they have a predetermined interval in the roof flow direction, and the lower end side of the first partition member and the second partition member are separated from each other. The upper end portion is held in a layout relationship in which it overlaps in level.

With such a structure, the first partition member and the second partition member can be held and the building wrapping material to be covered thereon can be held by the connecting members provided at a plurality of positions in the longitudinal direction of the flat ridge. You can do it. That is, it is possible to bear the overall strength burden only by the connecting member, and it is possible to reduce the weight and simplify the structure of the first partition member and the second partition member. Therefore, the material cost can be reduced and the handling and the construction of the flat building can be facilitated.

When viewed as a ventilation passage formed by this structure, the portion corresponding to the first partition member is not formed as a hole but as a gap formed between the lower end side and the roof member vertically. Alternatively, the portion corresponding to the second partition member may be formed not as a hole but as a gap formed between the upper end side of the second partition member and the upper and lower sides of the wrapping material. Therefore, material loss can be eliminated and the opening area of the ventilation passage can be effectively used. It should be noted that the first partition member and the second partition member can be made of materials that can be easily processed in terms of hardness and thickness, while the high-strength connecting member can be used as the first partition member and the second partition member. Since it is only provided in a scattered manner in the longitudinal direction of, the first partition material and the second partition material can be cut very easily according to the length of the flat roof ridge during the construction. There is also a side effect.

The first partitioning material is arranged on both sides of the ridge ventilation opening (that is, there are two), but these first partitioning materials mutually have an umbrella-shaped cross section of the building wrapping material. It may be connected and integrated via a transition plate portion provided along. This will lead to further simplification of the structure. The second partition member can be formed as a member having a standing height that extends from the upper surface side of the roof material to the rear surface side of the building wrapping material. In this case, it is assumed that the vent hole is formed at a predetermined height position of the plate surface of the second partition member (indicates a height position higher than the lower end side of the first partition member). At the lower end of the second partition,
It is assumed that the lower mounting piece that comes into contact with the upper surface of the roof material is bent, and that the upper mounting piece that comes into contact with the back surface of the building wrapping material is bent and formed at the upper edge of the second partition material. do it. That is, these two partition members, the lower mounting piece and the upper mounting piece may be integrally formed.

As a result, the simplification of the structure is further promoted. In addition, it is preferable that the second partition member has a drain hole near the lower end thereof. The first partition member and the second partition member may be formed of a material (e.g., a rubber plate or the like) having a strength enough to hold a predetermined shape by being connected to each other by a connecting member.
As a result, weight reduction and material cost reduction can be further promoted.

Therefore, centering on the ridge ventilation port 101,
The ventilation passages Y in two directions along the roof flow direction are formed between the roof material 104 on both sides of the roof material and the wrapping material 6 above and below. 2 and 3 show the ventilation passage forming member 5 described above. As is clear from FIG.
The first partition member 1 used for assembling the ventilation passage forming member 5 is formed so as to be bent downward on both sides of the crossing plate portion 10 having an umbrella-shaped cross section. That is,
There are two first partition members 1, and both of these first partition members 1 are connected and integrated via the transition plate portion 10.

The first partition member 1 is formed to be smaller than the height between the roof member 104 and the building wrapping member 6 (see FIG. 1).

Further, the umbrella-shaped cross-sectional shape of the crossing plate portion 10 is set to follow the umbrella-shaped cross-section of the ridge wrapping material 6 as an inclination angle, and the length in the roof flow direction is shorter than that of the ridge wrapping material 6. Has been formed. In addition, these first partition materials 1
The transition plate portion 10 is formed long along the longitudinal direction of the flat ridge portion.

For this reason, when a flat ridge structure is constructed using the ventilation passage forming member 5, the transition plate portion 10
Will be provided in a laminated shape (not in contact) so as to support the back surface side of the ridge wrapping material 6, and at this time, the first partition member 1 will be provided with the ridge ventilation opening 101 in the ventilation passage Y. It is positioned on both sides of the sandwich and on the higher side in the roof flow direction, and is provided so as to hang from the back surface side of the ridge wrapping material 6 in a direction that blocks the roof flow direction. As described above, the first partition member 1 is formed smaller than the height between the roof member 104 and the building wrapping member 6, so that the lower end side of the first partition member 1 extends to the roof member 104. Did not arrive,
A gap will be formed here, and this gap will be a part of ventilation passage Y.

The first partition member 1 and the transition plate portion 10 as described above.
Can be formed of a rubber plate (for example, EPDM), a thin sheet metal material, a resin plate, or a cloth. On the other hand, there are two second partition members 2 used for assembling the ventilation passage forming member 5, but these are formed separately from each other, unlike the case of the first partition member 1. Each second
The partition member 2 has a lower mounting piece 12 bent from the lower end side thereof, and an upper mounting piece 13 bent from the upper end side in the same direction as the lower mounting piece 12. The second partition member 2, the lower mounting piece 12, and the upper mounting piece 13 are integrally formed with a hook-shaped cross section.

The second partition member 2 has an upright height which extends from the upper surface side of the roof member 104 to the rear surface side of the ridge wrapping member 6 (see FIG. 1). Further, the second partition member 2 is formed with ventilation holes 15 composed of long holes or round holes at appropriate intervals along the longitudinal direction near the upper end side thereof, and at appropriate intervals along the longitudinal direction near the lower end side. Small-diameter drain holes 16 are formed at intervals. The second partition member 2, the lower mounting piece 12, and the upper mounting piece 13 are long along the longitudinal direction of the flat ridge.

For this reason, when a flat ridge structure is constructed using the ventilation passage forming member 5, the second partition member 2 is used.
Is positioned on the lower side in the roof flow direction (lower side position with a predetermined distance from the first partition member 1). In this state, the lower mounting piece 12 abuts on the upper surface of the roof member 104. It is used for fixing the second partition member 2 at this time,
In the ventilation passage Y, the roof member 104 is provided so as to stand from the upper surface side of the roof member 104 in a direction that blocks the roof flow direction. In addition, since the second partition member 2 has a standing height that reaches from the upper surface side of the roof member 104 to the rear surface side of the ridge wrapping member 6 as described above, the upper mounting piece 13 of the ridge wrapping member 6 is at this time. It comes into contact with the back surface and is used to fix it.

The ventilation hole 15 provided in the second partition member 2 is a part of the ventilation passage Y. Such second partition member 2, lower mounting piece 12 and upper mounting piece 1
3 can be formed of a rubber plate (for example, EPDM system), a thin sheet metal material, a resin plate, or a cloth. The connecting members 3 used for assembling the ventilation passage forming member 5 are provided at a plurality of locations in the longitudinal direction of the flat ridge, and are formed by crank-folding an elongated strip plate material along the roof flow direction into a predetermined shape. There is.

The top surface piece 23 is integrated so as to be bilaterally symmetric via the inclined upper end so that the whole has a mountain shape.

Therefore, the connecting member 3 is formed so as to cover the upper surface of the above-mentioned transition plate portion 10 on the back side (lower side) of the top surface pieces 23 on both sides, and at this time, the first member is formed on the inner surface of the first rising piece 20. The partition member 1 is held, and the outer peripheral surfaces of the interval holding piece 22 extending from the space holding piece 22 to the second upright piece 21 and the terminal piece 24 have the lower mounting piece 12, the second partitioning material 2, and the upper mounting piece 13 described above. The second partition member 2 is held by the outer surface of the second upright piece 21 at this time. Then, by being connected by the connecting member 3, the first partition member 1 and the second partition member 2 are held at a predetermined distance from each other in the roof flow direction. At the same time, the lower end of the first partition 1 and the second partition
The partition member 2 is maintained in a positional overlapping relationship with the upper end portion (which corresponds to the opening lower end of the vent hole 15 in the present embodiment since the vent hole 15 is provided). Become.

The connecting member 3 holds the first partitioning material 1 and the second partitioning material 2, and the strength required for connecting these to the wrapping material 6 (supporting the wrapping material 6). The material and the wall thickness are set so that In addition,
