Description

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 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 vents are assembled using standardized parts, the height of the small roof cannot be freely adjusted according to the structure of the building.

This invention was made based on the above-mentioned circumstances, and the height of the small roof forming the ventilation hole can be arbitrarily adjusted at the time of construction, thereby creating a slight vertical difference in the length direction of the roof. The purpose of the present invention is to provide a ventilation ridge structure in which the ridge part can be made horizontal.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing a ventilation ridge structure that is an embodiment of this 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 parallel to each other 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 plate-shaped first base material 8 made of a material with good sound insulation and heat insulation properties is provided on the upper surface of the plurality of main buildings 4.
is laid, and the first base material 8 is fixed to the main building 4 with an appropriate bonding member. On the upper surface of the spread first base material 8, a plurality of elongated support members 5 are arranged parallel to each other along the inclination direction of the roof main body 1.

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 similar to other first base materials arranged symmetrically around the ridge. A predetermined distance is provided between the support member 8A and the upper end of the other support member 5A in the inclination direction.

As shown in FIG. 2, 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 supporting members 5 and 5A, which are arranged parallel to each other from the ridge toward the eaves, have their ends abutted against the side surfaces of the narrow width portions 7 on the wide width portions 6 of the adjacent support members 5.
A plate-shaped second base material 9 made of a material with good sound insulation and heat insulation properties is placed. 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 coincides with the upper end surface of the support member 5. Therefore,
The roof portion, which is symmetrically formed around the ridge and is basically formed by the support member 5, the first base material 8, and the second base material 9, has a structure of an atrium 11 at the ridge. A plurality of roof sheets 10 are covered on the upper surface of the second base material 9. This roof board 10 is made by folding the upper edge 10A of a strip-shaped iron plate toward the upper side to form a chevron-shaped cross section, and by folding the lower edge to form a hook-shaped cross section toward the lower surface. 9, the main roof panels 10 are arranged so that the upper edge 10A of the chevron-shaped cross section faces upward, and one of the main roof panels 1
The edge of the chevron-shaped cross section at 0 is the main roof board 1
The main roof panels 10 are connected to each other by crossing the edges of the hook-shaped cross sections of other main roof panels 10 located above the main roof panels 10, thereby connecting the roof main body 1 with a plurality of main roof panels 10. It is like being covered.

The ventilation building 2 is configured as follows.

That is, a plurality of columns 12 are arranged on the upper surface of the ridgepole member 3 at appropriate intervals, for example, 150 to 200 cm, along the ridge direction, and the columns 12 are erected higher than the roof main body 1 through the atrium 11. do.

The support 12 has a rectangular cylindrical shape, and has a first screw hole 13 formed above the side surface. As shown in FIG. 3, a height adjusting member 14 having a U-shaped cross section in the direction of the ridge is inserted into the upper opening of the pillar 12, and a first horizontal member abuts on the outer surface of the pillar 12. A bolt 13A with a short leg is screwed into the second screw hole opened in 15 and the first screw hole 13, and by screwing the bolt 13A, the end of the leg of the bolt 13A strongly presses the side surface of the height adjustment member 14. Press this height adjustment member 1
4 is fixed to the pillar 12. Bolt 1 to be screwed together
Since the tip of the bolt 13A presses the side surface of the height adjusting member 14, any position on the side surface of the height adjusting member 14 can be pressed with the tip of the foot of the bolt 13A. Therefore, the support 1 of the height adjustment member 14
Since the fixing position to 2 can be adjusted steplessly, the height of each height adjusting member 14 can be adjusted as desired. Note that instead of the first screw hole and the second screw hole described above, a nut is fixed to the outer surface of the first horizontal member 15, and the bolt screwed onto the nut is passed through the hole made in the first horizontal member 15 and the support column 12. , the tip of the bolt may be crimped onto the height adjusting member 14. After the height of the height adjustment member 14 is set during construction of the roof, the height adjustment member 14 and the support column 12 may be integrated by welding or the like.

The first horizontal member 15 described above is a horizontally elongated plate-shaped body, and both ends in the longitudinal direction are bent into an L-shape, and the whole has a U-shape. It is attached to the support column 12 with the piece 15A facing toward the ridge.

The height adjusting member 14 has its opening upper end connected to the support column 12.
The pillar 12 should protrude so that it is higher than the upper end.
As shown in FIGS. 1 and 3, the open upper end of the height adjustment member 14 supports the rectangular tubular second horizontal member 16 in a sandwiched manner.

A square tubular first vertical member 17 is attached to both ends of the second horizontal member 16, and when viewed from the ridge direction, the second horizontal member 16 and the first vertical members 17 at both ends form an H shape. It's summery.

A rectangular cylindrical second vertical member 19 is attached to the outer surface of a portion of each first vertical member 17 below the first horizontal member 16 via an appropriate number of spacers 18A, 18B, for example. Also, the first left and right
At the upper end of each of the vertical members 17, metal rafters 20 are supported which are mountain-shaped when viewed in the direction of the ridge and have a hat-shaped cross section.

Since a plurality of supports 12 are arranged on the ridgepole member 3 at appropriate intervals along the ridge direction, the first vertical member 17, the second vertical member 19 and the metal rafter 20
are also arranged along the ridge direction.

A roof board 21 is laid on the top surface of the plurality of metal rafters 20 arranged through a base board (not shown) and a waterproof roofing material (not shown), and the roof of the ventilation ridge 2 is constructed. Form.

As shown in Fig. 4, the ridge portion of the roof of the ventilation ridge 2 is constructed by overlapping the edges of the roof plates 21 laid on each slope of the roof, and placing the edges of one roof plate 21 on the other roof. The end edge of the other roof board 21 is bent so as to be wrapped around the end edge of the board 21 to prevent rain from leaking from the ridge part.

The eaves part of the roof of ventilation building 2 is made of metal rafters 2.
A long arabesque member 22 is attached to the lower end of the slope along the ridge direction. That is, the inclined lower end of the metal rafter 20 is connected to the U-shaped portion 22A of the arabesque member 22.
At the same time, the eaves portion is housed in such a way that the lower end of the roof plate 21 is wrapped around the extending portion 22B extending in front of the U-shaped portion 22A.

A plurality of water guide plates 23 are vertically attached to the outer and inner surfaces of the second vertical member 19.

The water guide plate 23 is a plate-like member that is elongated along the ridge direction. As shown in FIG. 1, the cross section in the transverse direction is formed by bending the end edge to form a first inclined part 23A, and in the vicinity of the central part in the transverse direction, the first inclined part 23A is inclined in the direction of inclination. The first flat part 2 is bent in a direction away from the slanted part 23B to form a second slanted part 23B, and the first plane part 2 is bent in a direction away from the slanted part 23B.
3C, and bend the second inclined part 23B in the opposite direction to the first flat part 23C to form the first flat part 2.
A second plane part 23D is formed parallel to 3C, and an edge part of the second plane part 23D is formed into a second inclined part 23B.
The third inclined part 23E is formed by bending the third inclined part 23E in a direction away from the inclined direction of the second inclined part 23B on the same side as the second inclined part 23B. Then, with the first sloped part 23A positioned upward and the third sloped part 23E positioned downward, the second plane part 23D is brought into close contact with the inner and outer surfaces of the second vertical member 19, and the water guide plate 23 is positioned in the second position. Vertical member 1
9, and the plurality of water guide plates 23 are installed along the vertical direction so that the third inclined part 23E of the upper water guide plate 23 and the first inclined part 23A of the water guide plate 23 immediately below face each other. 2 arranged vertically on the vertical member 19.

A long waterproof sheet, such as a rubber sheet 24, is attached to the lower end of the inner surface of the second vertical member 19 along the ridge direction. The lower end of the rubber sheet 24 is suspended over the main roof board 10, and the upper end of the rubber sheet 24 is suspended over the second vertical member 19.
The rubber sheet 24 is sandwiched between the inner surface of the second vertical member 19 and the lowest water guide plate 23 of the water guide plates 23 arranged on the inner surface of the second vertical member 19.
Attach to. Therefore, in the second vertical member 19,
Even if rainwater infiltrates into the pair of water guide plates 23 that are attached to face each other with this in between, the rainwater flows down through the second vertical member 19, and then,
It will be guided by the rubber sheet 24 and will flow down onto the main roof board 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 into the ventilation building 2 through the atrium 11. The user exits outdoors through the opening in the guide plate 23, thereby making it possible to ventilate the indoor space.

In addition, in the case of rainy weather, even if rainwater falls into the water guide plate 23, the rainwater will flow through the second slope portion 23B, second flat portion 23D, and third slope portion 23E, and the water guide plate located below In this way, the rainwater flows down the arranged water guide plates 23, and finally flows through the rubber sheet 24 to the main roof board 10, so that the rainwater that has fallen flows into the ventilation building 2. There is no possibility of infiltration. In addition, in the ventilation ridge 2, a water return member is attached to the first horizontal member 15 and engages with the uppermost main roof board 10 on the sloped surface of the roof among the main roof boards 10 covering the roof main body 1. 25, so even if ventilation building 2
Even if rainwater intrudes into the water return member 2
5 can prevent rainwater from entering indoors.

In addition, the screw hole 1 opened in the upper part of the support 12
Since the height adjustment bolt 13A is screwed into the height adjustment member 3, the height of the ventilation ridge 2 can be adjusted to a certain extent by changing the mounting position of the height adjustment member 14 to the support column 12 steplessly during construction. For example, even if the ridgepole member 3 has a vertical difference along the ridge direction, the ventilation ridge 2 can be made horizontal by adjusting the vertical position of each height adjusting member 14 with a water string.
Moreover, after adjusting the height of each height adjustment member 14,
The height adjustment member 14 and the support column 12 may be welded into one piece on site.

Furthermore, the belt 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. The pillars 12, height adjustment members 14, horizontal members, vertical members, etc. are not limited to the shapes shown in the drawings, and C-shaped steel or any other shapes may be used.

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 this invention. Nor.

Instead of attaching the water guide plate 23 to the second vertical member 19 as in the previous embodiment, the water guide plate 23 may be attached to the second vertical member 19 as shown in FIG. That is, the water guide plate 23 shown in FIG. 5 has the same shape as the water guide plate 23 in the previous embodiment. Then, the third inclined portion 23E is moved upwardly, and the first
The water guide plate 23 is attached to the outer surface of the second vertical member 19 with the inclined part 23A positioned downward, and the first inclined part 23A of the upper water guide plate 23 and the third inclined part of the lower water guide plate 23 are attached. The plurality of water guide plates 23 are connected to the second vertical member 19 so that the water guide plates 23E and 23E face each other.
Arrange on the outer surface of. The manner in which the water guide plates 23 are attached and arranged on the inner surface of the second vertical member 19 is the same as in the previous embodiment.

If the method of attaching and arranging the water guide plate 23 as shown in FIG. This is convenient because it makes it easier to fall upwards.

As detailed above, according to the ventilation ridge structure according to the present invention, the height adjustment member is fixed by the bolt that is screwed into the column, so by arbitrarily varying the pressing position of the bolt, it is possible to The height of the second horizontal member attached to the support can be adjusted to make the overall height the same. As a result, even if there is some vertical difference in the length direction of the ridge, the ventilation ridge can be installed horizontally at an appropriate height, which is not only structurally reasonable, but also allows the ventilation amount to be adjusted. can. Therefore, ventilation can be performed with an amount of ventilation depending on the nature of the building, such as a gymnasium or factory building.
