DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skylight (toplight, skylight), and more particularly to a large-area skylight provided on an inclined roof of a building or the like.

[0002]

2. Description of the Related Art Conventionally, some buildings such as buildings have skylights provided on an inclined roof. Such a skylight is a daylighting window provided on the roof of a building, and is widely used in recent years because it can be used as a building having a larger amount of daylight than a daylight from a window on a wall surface and having an excellent design. It was started.

[0003] As a construction method of such a skylight, a unit construction method and a knockdown construction method are known. In the unit construction method, a plurality of units are formed by fitting a panel such as glass into a rectangular frame made of vertical and horizontal members at a factory, and a skylight is assembled by sequentially arranging these units at a construction site. In the knockdown method, each of the long vertical frame material, the long horizontal frame material, and the panel is individually brought to a construction site, and at this construction site, each frame material is joined in a lattice shape, and these are joined together. The skylight is assembled by fitting the panel into the opening defined by the frame material.

[0004]

However, when a plurality of units are arranged along the vertical direction (direction along the water gradient) and the horizontal direction (direction perpendicular to the water gradient) by the unit construction method, Since joints exist continuously over the entire circumference of the unit, there has been a problem that the water stopping process of the joints becomes complicated. In addition, below the skylight, a vertical gutter and a horizontal gutter receiving the rainwater are often provided so that the water stopping performance is maintained even if the rainwater leaks from the joint. There is a problem that a water gradient in a different direction perpendicular to the water gradient must be provided, and this gutter must be communicated with the down gutter, which makes installation of the gutter at a construction site troublesome.

On the other hand, according to the knockdown method, since each component is individually brought to the construction site, it is difficult to perform the construction at the construction site in a short construction period. Furthermore, according to the knockdown method, although there are no continuous long joints or gutters below the joints, the connection between the vertical frame material and the horizontal frame material has a complicated structure. It is not easy to apply water stoppage treatment. Therefore, the complexity of the water stopping process cannot be completely eliminated, and there is a limit to improving the water stopping performance.

An object of the present invention is to provide a skylight capable of improving water stoppage and workability at a construction site.

[0007]

The skylight of the present invention reduces the number of joints by devising the shape and the like of the constituent members.
It is intended to achieve the above object. In particular,
The skylight of the present invention is a skylight provided on a sloped roof portion, and a unit frame is formed from a pair of vertical frame materials arranged along the slope and a blind material arranged in advance between the vertical frame materials. The vertical frame members of the plurality of unit frames are connected to each other at one end to form an opening section defined by each vertical frame member and the seamless material, and a panel is arranged in this opening portion. Things.

According to the present invention, since the skylight is assembled by connecting one ends of the vertical frame members to each other, the joint in the horizontal direction has a short length only between the ends of the vertical frame members. There will only be joints. In addition, by performing the water stopping process of the connection portion between the vertical frame material and the seamless material, for example, in advance at a factory or the like, even if the structure of the connection portion is complicated, the water stopping process can be performed efficiently and reliably. . Therefore, the water stopping process at the construction site becomes easy, and the conventional complexity is eliminated.
In addition, since there is no need for a horizontal gutter because there is no long joint in the horizontal direction, the trouble of installing the horizontal gutter can be omitted, and if the vertical frame material and the seamless material are connected in advance at a factory or the like, for example, the construction site In this case, it is only necessary to connect the unit frames or fit the panel into the opening between the connected unit frames, so that the skylight can be quickly constructed and the workability on the site is improved.

In the skylight of the present invention, at least one of the plurality of unit frames is connected to each of the vertical frame members in advance by a plurality of blind members.
A panel may be arranged in advance in an opening defined by each vertical frame material and each seamless material. In such a case, a part of the panel constituting the skylight is fitted in advance in a factory or the like, for example, whereby the number of panels fitted in the construction site is reduced, and the on-site work is further reduced.

In the present invention, the openings may be formed as a plurality of openings by at least one longitudinal middle aggregate disposed between the blanks. In such a case, the rigidity of the skylight is improved by providing the longitudinal middle aggregate.

Further, in the skylight of the present invention, each vertical frame member is
A plurality of vertical members arranged on a straight line with a gap between each other,
And a joint sleeve for connecting the vertical members, and these joint sleeves may be slidably connected to at least one of the vertical members connected via the joint sleeve. . When the vertical frame material thermally expands with an increase in temperature, the dimensional elongation at that time is remarkably exhibited particularly in the longitudinal direction. But,
When the vertical members constituting the vertical frame are connected by a slidable joint sleeve, the expansion due to the expansion of each vertical member is absorbed by the gap between the vertical members due to the sliding of the joint sleeve. Therefore, the entire vertical frame material is hardly affected by the temperature. In addition, the size of the unit frame is determined in units of a module of a predetermined size, but if the vertical frame material is composed of a plurality of vertical materials, the vertical frame material is manufactured by a continuous integral shape. You don't have to. For this reason, a vertical frame member longer than that of a case where the unit frame is manufactured by an integral member can be obtained, and a large module unit frame can be manufactured.

In the skylight of the present invention, a plurality of unit frames are arranged side by side at right angles to the inclination, and a gutter is formed along joints between the vertical frame members of the unit frames arranged side by side. It may be provided. In such a case, the unit frame is also arranged in a direction orthogonal to the inclination (water gradient), and even if a skylight with a larger area is formed, the unit frame is formed along the joints between the vertical frame members facing each other in the horizontal direction. Since the gutter is provided, even if rainwater leaks from the joint, the rainwater is surely drained to the downstream side. At this time, since the gutters are provided along the joints, the gutters automatically have a water gradient in the same direction as the water gradient of the skylight. Workability is not hindered.

[0013] In the skylight of the present invention, the gutter is an upper primary gutter provided integrally with at least one of the vertical frame members facing each other via joints, and each of the vertical frame members. And a secondary gutter arranged at a lower position of the second gutter. In such a case, even if rainwater overflows from the primary gutter, it can be received by the secondary gutter, so that leakage of rainwater is more reliably prevented, and the water stopping performance is further improved.

Further, in the skylight of the present invention, a seal member is disposed at a position above the gutter between joints between the unit frames, and the joint between the unit frames and the joint along the inclination are formed along the inclination. The intersection with the orthogonal joints is concealed by a cover member fixed to one of the unit frames forming the intersection, and the periphery of the cover member and each unit frame and the seal member forming the intersection are connected to each other. It is preferable that another seal member is interposed between them.

The seal member disposed at the joint is repeatedly compressed by the thermal expansion or contraction of each unit frame, and the effect is particularly remarkable at the intersection of the joint. That is, at the intersection of the joints, peeling of the seal member is promoted by repeated compression. Therefore, if the intersection is concealed by a cover member and another seal member is interposed between the peripheral edge of the cover member and each unit frame and the seal member, the other seal member can be thermally expanded or contracted by the unit frame. Therefore, there is no gap between the seal member and the cover member, the unit frame, and the previous seal member. Therefore, no rainwater is applied to the intersection of the joints surrounded by the seal member, and even if the seal member filling the intersection is peeled off, the water stoppage does not decrease. Furthermore, by concealing the intersection with the cover member, deterioration of the seal member due to ultraviolet rays is prevented, so that the durability of the seal member against repeated compression is improved, and the seal member is more difficult to be peeled off.

In this embodiment, the skylight 10 is constructed as follows. First, in the factory,
A plurality of unit frames 11 are assembled from the vertical frame member 15, the blind material 16, the vertical middle aggregate 17, and the glass panel 19. At this time, the joint sleeve 20 is arranged on one end side of the vertical frame member 15, and the gutter member 30 constituting the primary gutter 36 is arranged on the vertical frame member 15A in advance.
Next, the on-site construction members such as the unit frame 11 and the glass panel 14 are carried to the construction site.

At the construction site, the gutter member 34 is bridged and fixed to a plurality of receiving objects 65 provided on the building frame 3, and the gutter members 34 are connected to each other by the connecting member 37 to complete the secondary gutter 40. . Thereafter, the unit frames 11 are placed on the receiving surface 66 of the metal receiving object 65, and are arranged side by side in the vertical and horizontal directions.
Are connected via a joint sleeve 20. At this time, the gutter member 30 of each unit frame 11
The primary gutter 36 is completed by connecting them with a connecting member 35. Further, the longitudinal middle aggregate 13 and the glass panel 14 are arranged in the openings 12 formed by disposing the unit frames 11.

Next, at each joint 21 and 22, sealing members 53 and 55 are arranged between the vertical frame members 15 which are close to and opposed to each other to perform a water stopping process. Finally, the intersection C of each joint 21 and 22 is formed. It is concealed by a cover member 61 and sealed by a seal member 62.

According to the present embodiment, the following effects can be obtained. That is, in the skylight 10, the connection of the unit frames 11 arranged in the vertical direction is performed at the end A of the opposed vertical frame member 15, and therefore the horizontal joint 21 is about the width dimension of the combined vertical frame members 15. And the long horizontal joints existing in the conventional unit construction method can be omitted. In addition, since the water stopping process can be performed in advance at the factory at the intersection of the vertical frame member 15 and the blind material 16, the water stopping process can be performed efficiently and reliably, and the on-site processing is unnecessary. . Therefore, at the construction site, the joint processing can be greatly simplified and easily performed, and the waterproofness can be improved.

Then, the intersection C between the peripheral edge of the aluminum plate 59 constituting the cover member 61 and each of the joints 21 and 22 is formed.
A continuous seal member 62 is disposed between each unit frame 11 forming the seal member. However, since the seal member 62 is disposed at a position where the seal member 62 is not repeatedly subjected to compression, the seal member 62 is extended. It can be kept in close contact for a period. For this reason, no rainwater is applied to the intersection C surrounded by the seal member 62, and the seal member 5
Even if peeling occurs at 3, 55, rainwater does not leak from intersection C.

At this time, since the intersection portion C is concealed by the cover member 61, the sealing materials 53B and 55B filled in the joints 21 and 22 are prevented from being deteriorated by ultraviolet rays. 55 is hardly peeled off even when repeatedly subjected to compression due to expansion and contraction of the unit frame 11, and can maintain good water stopping performance.

Each of the joints 21 and 22 is connected to each of the gutters 3.
6 and 40, and since the unit frame 11 is pre-fabricated at the factory, after the unit frame 11 is arranged at the construction site,
3 and the glass panel 14 only need to be incorporated, and a conventional gutter can be dispensed with, and the installation work of the gutter can be omitted. Therefore, compared with the conventional unit construction method or the knockdown construction method, the skylight 10 can be constructed on site more quickly, and workability on site can be improved.

Furthermore, since the joint sleeves 20 are provided in advance in the vertical frame members 15 of the unit frame 11 at the factory, when the unit frames 11 are arranged along the vertical direction at the construction site, the connecting members are required. Can be saved separately. Further, the connection operation may be performed by sliding the joint sleeve 20 to engage with the vertical frame member 15 of the unit frame 11 on the downstream side, and the connection operation can be easily performed. At this time, the joint sleeve 20
Of the vertical frame material 15 can be absorbed by the gaps between the vertical frame materials 15, and the internal stress in the unit frame 11 can be absorbed. Is less likely to occur.

Since the primary and secondary gutters 36 and 40 are provided below the vertical frame member 15, even if rainwater leaks from the joints 21 and 22, the rainwater can be drained reliably. Further, since the primary gutter 36 and the secondary gutter 40 are separated, even if rainwater overflows from the primary gutter 36,
Rainwater can be reliably received, and the water stoppage can be further improved. At this time, the gutter members 30 and 34 constituting the primary and secondary gutters 36 and 40 are joined at positions shifted from the horizontal joints 21.
Water stoppage can be reliably maintained.

Then, the gutter member 30 is previously set at the factory by the vertical frame material 1.
5A, the primary gutter 36 can be easily formed at the construction site, and the gutter member 34 is bridged between the receiving members 65 so that the secondary gutter 40 along the water gradient can be formed. Since it can be easily formed, the installation work of the primary and secondary gutters 36 and 40 can be performed without trouble, and it is possible to prevent the workability on the site from being hindered.

Further, since the longitudinal windows 13 and 17 are used for the skylight 10, the rigidity of the entire skylight 10 can be increased. In particular, since the unit frame 11 was configured using the longitudinal middle aggregate 17, the unit frame 11
When transported from the factory to the construction site, it can be easily handled without being distorted due to lack of rigidity.

Further, since the maintenance pipe 77 is provided on the outer periphery of the skylight 10, a rope or the like is laid between the maintenance pipes 77, and the work is performed using the rope to clean or repair the skylight 10. Maintenance can be performed safely.

The connecting portion between the maintenance pipe 77 and the connecting member 78, that is, the maintenance pipe 77
Since the welded portion between the second tubular member 82 and the second tubular member 82 is hidden by the first tubular member 81 of the connecting member 78, no trace of the bead is exposed, and the appearance of the maintenance pipe 77 can be improved.

FIGS. 13 and 14 show a unit frame of a skylight according to a second embodiment of the present invention. Note that the same reference numerals are given to the same components as those in the above-described embodiment, and detailed description thereof will be simplified or omitted.

In FIGS. 13 and 14, each vertical frame member 115 of the unit frame 111 has an upstream vertical member 116, a downstream vertical member 117, and a vertical member
6 and 117 are connected to each other. A gap is formed between the vertical members 116 and 117, and the vertical members 116 and 117 and the joint sleeve 118 are connected by two bolts 119 and three bolts 119, respectively.

Of the three bolts 119 connecting the downstream vertical member 117 and the joint sleeve 118, two bolts 119 A are formed in the long holes 1 formed in the vertical member 117.
The bolt 119B which is inserted into the unit frame 20 and is indicated by a two-dot chain line is used at the time of assembling the unit frame 111 at a factory, and is removed after the unit frame 111 is arranged at the construction site. The gap between the vertical members 116 and 117 is set in advance at the factory by the sealing material 1.
At 21 and the like, a water stopping process is performed.

When such a unit frame 111 is used, the following effects are obtained in addition to the effects of the above-described embodiment. That is, when the skylight is completed, the vertical members 116 and 117 constituting the vertical frame member 115 are formed.
Of the vertical members 117 on the downstream side, the joint sleeve 11 is formed only by bolts 119A inserted into the long holes 120.
8, when thermal elongation or the like occurs in each of the vertical members 116 and 117, the joint sleeve 118 is connected to the long hole 1.
20 along the major axis direction, and the elongation of each
It becomes absorbed in the gap between 16, 117. Accordingly, the amount of thermal elongation generated at the upper and lower ends of the vertical frame member 115 can be reduced, so that the compressive force acting particularly on the horizontal joint can be reduced, and peeling at the intersection of the joint can be suppressed more effectively. Further, by suppressing the thermal elongation, the internal stress in the unit frame 111 can be further reduced.

The vertical frame member 115 is formed by each of the vertical members 116, 1
Since it is composed of 17 pieces, there is no need to manufacture it with a continuous and integral shape. For this reason, it is possible to make the vertical frame member 115 longer than in the case where the vertical frame member 115 is made of an integral material, and to make the unit frame 11 larger.

FIG. 15 shows a unit frame of a skylight according to a third embodiment of the present invention. In this embodiment, the same reference numerals are given to the same components as those in each of the above embodiments, and detailed description thereof will be simplified or omitted.

In FIG. 15, the unit frame 211
Is composed of a pair of vertical frame members 215 and a single blind material 16 connecting them, and does not include a glass panel for factory construction as in the above embodiments. That is, when this unit frame 211 is used, the unit frame 211 is assembled in advance in a factory or the like by using the vertical frame members and the blind material 16, and all the glass panels 14 constituting the skylight are fitted at the construction site.

Even in such an embodiment, the water stopping performance and workability at the site can be sufficiently improved as compared with the conventional unit construction method and knockdown construction method. In addition, since the type of the panel is only the glass panel 14 for on-site construction, management of the members and the like can be easily performed.

The present invention is not limited to the above embodiment. For example, in the first and second embodiments, in the pair of unit frames 11 and 111 arranged along the vertical direction, each of the vertical frame members 15 and 115 is connected by three seamless members 16, In the third embodiment, each of the vertical frame members 215 is connected by one seamless material 16, but the number of the seamless materials connecting the vertical frame materials is arbitrary. However, if a plurality of blanks are used as in the first and second embodiments, a plurality of panels can be fitted in the factory in advance, and the number of panels for on-site construction can be reduced to reduce the number of on-site panels. It is preferable to do so because the effect of reducing the work can be obtained. Further, for example, the skylight may be configured by combining unit frames having different numbers of blanks, such as combining the unit frames 11, 111, and 211 in each embodiment.

Further, in the first and second embodiments, one longitudinal middle aggregate 17 is used between each seamless material 16 of the unit frames 11 and 111. The number of medium aggregates may be determined as appropriate in consideration of the size of the skylight and the required rigidity, etc. In addition, when sufficient rigidity can be secured with the vertical frame material or the blind material, the third implementation is carried out. As in the embodiment, the longitudinal middle aggregate may be omitted. Note that the same applies to the longitudinal middle aggregate 13 for on-site construction described in the first embodiment.

The unit frame disposed at the lowermost or uppermost position of the skylight may have a structure in which the lower and upper ends of the vertical frame members are connected by horizontal members instead of the structure as in the above-described embodiments. Good. That is, for example, in the unit frame arranged at the lowermost end of the skylight, by connecting another unit frame only to the upstream side, an opening for fitting a panel for on-site construction may be formed.
In the unit frame arranged at the uppermost end, another unit frame may be connected only to the downstream side to form an opening.

Further, the structures of the cover member 61 and the joint sleeves 20 and 118 are not limited to those of the first and second embodiments, but may be appropriately determined in consideration of the cross-sectional shape of the vertical frame member or the like. The structure may be used. For example, the above-described cover member 61 is composed of a fixing member 58 and an aluminum plate 59, and the fixing member 58 is a single unit frame 1
Although it is designed to be screwed to 1, an aluminum plate may be simply disposed via a sealing member without using a fixing member. In the joint sleeves 20, 118, the elongated holes 27, 12 provided on the side of the vertical frame members 15, 115 are provided.
Although it was slidable by 0, such a long hole may be provided on the joint sleeve side. However, the cover member and the joint sleeve are not indispensable to the present invention, and can be omitted as appropriate in implementing the present invention. However, by using a cover member and a joint sleeve,
This is preferable because the effects described above can be obtained.

In the first embodiment, the primary gutter 36 and the secondary gutter 40 are provided. However, the present invention includes a vertical gutter provided with any one of them. It is. However, by providing the primary gutter and the secondary gutter separately, the water stoppage may be improved.

The planar shape of the entire skylight of the present invention is not limited to a rectangle as in the first embodiment, but may be any other polygon, circle, ellipse, etc. Alternatively, it may be arbitrarily determined in consideration of the overall shape of the building and the like.

[0067]

As described above, according to the present invention, the connection of the unit frames arranged along the slope is performed by connecting the ends of the vertical frame members constituting these unit frames. In addition, it is possible to improve the water stopping performance by making the horizontal joint formed at the connection portion short. Also, since the unit frame is made by connecting the vertical frame material in advance with a blind material at the factory, at the construction site,
It is only necessary to fit a panel for on-site construction after disposing each unit frame, and there is an effect that workability on the site can be improved.
