DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation building structure that can be easily manufactured by assembling parts that can be mass-produced in a factory on-site, and whose height above the floor can be adjusted as appropriate. .

Conventionally, when installing ventilation holes in the roof ridges of factories, warehouses, gymnasiums, etc., the method used was to build louvers or small roofs on top of the main building or rafters and install the ventilation holes, but this method did not meet the standards. Since the ventilation openings are assembled using standardized parts, it is not possible to freely adjust the height of the small roof according to the character of the building.

This invention was made based on the above-mentioned circumstances, and an object thereof is to provide a ventilation ridge structure in which the height of a small roof forming a ventilation opening can be arbitrarily adjusted.

The outline of this invention for achieving the above object is as follows:
The insertion body is inserted into the atrium formed in the ridge part of the roof main body, and a plurality of columns are erected along the ridge direction and the height of the insertion body is fixed so as to be adjustable, and the height is adjusted to the same height. A long support member extending in the ridge direction is fixed to the body, and a horizontal member having at both ends thereof at least a pair of vertical members supporting the roof of the ventilation ridge is attached to the long support member. It is characterized by being placed and fixed so as to be perpendicular to the .

Next, the present invention will be described with reference to one embodiment along with the drawings.

FIG. 1 is a sectional view showing a ventilation ridge structure according to an embodiment of the present invention.

As shown in FIG. 1, the ventilation structure has a symmetrical configuration with respect to a perpendicular line passing through the ridge, and forms a ventilation ridge 2 above the roof main body 1.

The roof main body 1 is constructed as follows. That is, one end of a diagonal chord member (not shown) is placed on the ridgepole member 3, and a plurality of chord members that are inclined from one end to the other end are arranged in parallel along the ridge direction. A plurality of metal purlins 4 having a channel-shaped cross section are arranged on the string members at appropriate intervals in a direction perpendicular to the longitudinal direction of the string members.

A plurality of plate-shaped first base materials 8 made of a material with good sound insulation and heat insulation properties are laid on the upper surface of the plurality of main buildings 4, and the first base materials 8 are connected to the main buildings 4 with suitable joining members. Fix it. On the upper surface of the spread first base material 8, a plurality of elongated support members 5 are arranged parallel to each other according to the slope of the chord members.

The first base material 8 and the support member 5 both have their upper ends aligned in the inclination direction of the roof main body 1, and their upper ends are connected to another first base material arranged symmetrically around the ridge. 8A and the upper end of the other support member 5A in the inclination direction,
A predetermined interval is provided.

As shown in FIG. 3, when viewed from the inclination direction of the roof main body 1, the support members 5, 5A have a wide portion 6 that is wide in the transverse direction, and a wide portion 6 that protrudes from the upper surface of the wide portion 6. In this embodiment, the wide width part 6 has a lower part open and a flange extending from side to side. It has a structure in which the upper part of the part 7 is closed.

The support members 5 and 5A arranged parallel to each other in the direction of the ridge are connected to the wide part 6 of the adjacent support member 5.
A plate-shaped second base material 9 made of a material with good sound-insulating and heat-insulating properties is placed on top, with its end abutting against the side surface of the narrow width portion 7 . Therefore, an air layer is formed between the first base material 8 and the second base material 9. Further, the upper end surface of the second base material 9 in the inclination direction coincides with the upper end surface of the support member 5 in the longitudinal direction. Therefore, the supporting member 5, the first base material 8 and the second base material 8 are arranged symmetrically around the ridge.
The roof portion formed based on the base material 9 has a structure with an atrium 11 at the ridge. A plurality of roof sheets 10 are covered on the upper surface of the second base material 9.
The present roofing board 10 is made by, for example, folding one end 10A of a band-shaped iron plate so as to form a chevron-shaped cross section on the upper surface side, and folding the other end edge 10B so as to form a hook-shaped cross section on the lower surface side. Following the slope of the base material 9,
The main roof boards 10 are arranged so that one end edge 10A of the chevron-shaped cross section is upward, and the end edge 10A of the chevron-shaped cross section of one main roof board 10 is placed above the main roof board 10.
The main roof boards 10 are connected to each other by crossing over the edge 10B of the hook-shaped cross section of the main roof board 10 located above, thereby covering the roof body 1 with a plurality of main roof boards 10. It's becoming like that.

The ventilation building 2 is configured as follows.

That is, a plurality of supports 12 are arranged on the upper surface of the ridgepole member 3 along the ridge direction at appropriate intervals, for example, at intervals of 250 cm.

In this embodiment, the height of the upper end of the support column 12 is adjusted to be approximately the same as the upper end of the second base material 9.

This support 12 has a rectangular cylindrical shape, and as shown in FIG. 4, a nut 13 is provided on at least one side surface. This nut 13 is provided to mount a bolt to enable stepless adjustment of the height of the insert body, which will be described later. As shown in FIG. 1, substantially L-shaped angle plates 14 with vertically bent tips are horizontally attached to both sides of the support column 12 along the ridge direction. One end 15A of the water-shielding plate 15 is formed by bending the substantially central portion of the main roof plate 10 into a substantially L-shape.
The main roofing board 10 is laid on the top surface of the second base material 9.
By locking it to one end of the chevron-shaped cross section of the water shield plate 15, the almost central part of the water shield plate 15 that stands up vertically is fixed to the vertical surface of the angle plate 14, and the water shield plate 15 is secured to the vertical surface of the angle plate 14, so that the water shield plate 15 can not penetrate into the ventilation building 2.

A plurality of metal rafters 26 are also arranged along the ridge direction.

A roof board 28 is laid on the top surface of the plurality of arranged metal rafters 26 via a base board (not shown) and a waterproof roofing material (not shown), and the roof of the ventilation ridge 2 is constructed. Form.

The ridge portion of the roof of the ventilation ridge 2 overlaps the edges of the roof panels 28 laid on each slope of the roof, and wraps the edge of one roof panel 28 with the edge of the other roof panel 28. The edge of the other roof plate 28 is bent to prevent rain from leaking from the ridge.

The eaves part of the roof of ventilation building 2 is made of metal rafters 2.
An elongated arabesque member 29 is attached to the lower end of the sloping part 6 along the ridge direction. That is, the inclined lower end of the metal rafter 26 is sealed with the U-shaped portion of the arabesque member 29, and the inclined lower end of the roof board 28 is wrapped around the key portion 29B extending behind the U-shaped portion 29A. Install the eaves part.

A plurality of water guide plates 30 are attached to the outer and inner surfaces of the second vertical member 25 along the vertical direction.

The water guide plate 30 is a long plate-like member extending in the ridge direction. As shown in FIG. 1, the cross section in the transverse direction is formed by bending the edge to form a first inclined part 30A, and in the vicinity of the central part in the transverse direction, the first inclined part 30A is inclined in the direction of inclination. The first flat part 3 is bent in a direction away from the slanted part 30B to form a second slanted part 30B, and the first plane part 3 is bent in a direction away from the slanted part 30B.
0C, and the second inclined portion 30B is bent in the opposite direction to the first flat portion 30C to form the first flat portion 3.
A second plane part 30D is formed which is flat with 0C, and an edge part of the second plane part 30D is formed into a second inclined part 30B.
The third inclined part 30E is formed by bending the third inclined part 30E in a direction away from the inclined direction of the second inclined part 30B on the same side as the second inclined part 30B. Then, with the first sloped part 30A positioned upward and the third sloped part 30E positioned downward, the second plane part 30D is brought into close contact with the inner and outer surfaces of the second vertical member 25, and the water guide plate 30 is placed in the second position. Vertical member 2

A long waterproof sheet, such as a rubber sheet 31, is attached to the lower end of the inner surface of the second vertical member 25 along the ridge direction. The lower end of the rubber sheet 31 is suspended over the main roof board 10, and the upper end of the rubber sheet 31 is suspended over the second vertical member 25.
The rubber sheet 31 is sandwiched between the inner surface of the second vertical member 25 and the lowest water guide plate 30 of the water guide plates 30 arranged on the inner surface of the second vertical member 25.
Attach to. Therefore, in the second vertical member 25,
Even if rainwater infiltrates into the pair of water guide plates 30 that are attached so as to sandwich and face each other, the rainwater will run down the second vertical member 25, and then be guided by the rubber sheet 31 to the main roof board. It will flow down to 10.

Since the ventilation ridge structure is configured as described above,
Indoor air rises into the ventilation building 2 through the atrium 11, and then the air inside the ventilation building 2 rises through the arranged first vertical member 23, second vertical member 25, and water arranged in the second vertical member 25. It exits outdoors through the gap between the guide plates 30, thereby making it possible to ventilate the indoor space.

In addition, in the case of rain, even if rainwater falls into the water guide plate 30, the rainwater will flow through the second slope portion 30B, second flat portion 30D, and third slope portion 30E, and the water guide plate located below In this way, the rainwater flows down the arranged water guide plates 30, and finally flows through the rubber sheet 31 to the main roof board 10, and the rainwater that has fallen into the ventilation building 2. No infiltration. In addition, inside ventilation building 2,
Of the main roofing sheets 10 covering the roof body 1,
Water shielding plate 1 engaged with the uppermost main roof plate 10 on the sloped roof surface and attached to the angle plate 14
5 is provided, even if rainwater infiltrates into the ventilation building 2, the water shielding plate 15 can prevent the rainwater from infiltrating indoors.

In addition, since a height adjustment bolt 17 is screwed into a nut 13 on the side of the support column 12, the height of the ventilation building 2 can be adjusted steplessly by varying the height of the insert 16 during construction. Even if the ridgepole member 3 has a vertical difference along the ridge direction, the ventilation ridge 2 can be installed horizontally by adjusting the height of the individual inserts 16.

Furthermore, the full load of the ventilation ridge 2 is not applied to the main building 4 or the support members 5, 5A, but is applied to the purlin member 3 via the support column 12, and the purlin member 3 is supported by a strong support column (not shown). Therefore, the ventilation building 2 can be stably and reliably supported.

Note that the support column 12, the insert body 16, and the elongated support member 1

Although one embodiment of this invention has been described in detail above, this invention is not limited to the above embodiment, and it goes without saying that it can be implemented with appropriate modifications within the scope of the gist of the invention. Nor.

Instead of attaching the water guide plate 30 to the second vertical member 25 as in the previous embodiment, the water guide plate 30 may be attached to the second vertical member 25 in the following manner. That is, the water guiding plate 30 having the same shape as that in the above embodiment is used, and the third inclined portion 3 is
The water guide plate 30 is attached to the outer surface of the second vertical member 25 so that 0E is located upward and the first inclined part 30A is located downward, and the first inclined part 30A of the upper water guide plate 30 and the lower water guide Third inclined portion 30E of plate 30
A plurality of water guide plates 30
are arranged on the outer surface of the second vertical member 25. The manner in which the water guide plates 30 are attached and arranged on the inner surface of the second vertical member 25 is the same as in the previous embodiment.

If such a method of attaching and arranging the water guide plate 30 is adopted, snow that has fallen on the water guide plate 30 will fall onto the main roof shingle 10 due to the slope of the second slope portion 30B in areas with heavy snowfall. This is convenient because it becomes easier.

FIGS. 6 and 7 show another embodiment of the present invention, in which the height is adjusted by inserting the inserts 16 into each of the upright columns 12 at appropriate intervals, and attaching the columns 12 with tapping screws 17'. After fixing the and insert body 16,
Two Cs are attached to the base plate 18 provided at the upper end of each insert 16.
The steel-shaped long support members 19, 19 are spanned backwards, and the base plate 18 and the both long support members 19, 1 are connected by bolts 21A passed between both the long support members 19, 19.
Both elongated support members 19, 19 are fixed by tightening a presser plate 20 disposed on the upper surface of the support member 9. Then, the horizontal member 21 is arranged perpendicularly on the upper surface of both the long support members 19, 19, and the horizontal member 21 and the long support member 1
9 and 19 are integrated with a fastener 32. This fastener 3
