BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof outer wall structure suitable for a building requiring air tightness such as a clean room.

[0002]

2. Description of the Related Art In a conventional building in which the outer wall and the roof of the building are made of different members, a gap called a door is formed at the joint between them. For this reason, when airtightness is required for the building, a face door plate for closing the face door is provided and all the remaining gaps are filled with caulking material. In addition, since airtightness and heat insulation are required in clean rooms, etc., the roof and outer wall members are covered with heat-insulating panels, and urethane foam etc. are sprayed on the entire surface to finish the interior finish. Was there.

[0003]

However, in order to completely seal the joining portion between the outer wall and the roof, the caulking material must be sufficiently filled so that no gap remains, which is troublesome and complicated. Work has to be done, and a great deal of time and money has to be spent. Also,
It was difficult to confirm the state of the caulking material filled in the gap from the outside, and ensuring the airtightness was left to the experience and intuition of the operator. Further, when the building is required to have heat insulating properties, it is necessary to spend time and money for the work of providing the interior finish having heat insulating properties on the inside of the roof member and the outer wall member, and the construction period is prolonged. There was a problem that construction costs would rise.

The present invention has been made in view of the above-mentioned problems, and provides an inexpensive roof outer wall structure which reliably seals the joint between the outer wall and the roof, has high airtightness, and can be installed in a short period of time. The purpose is to

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the roof outer wall structure of the present invention is applied to a clean room which is required to have airtightness and heat insulation will be described below with reference to the drawings. Figure 1
FIG. 3 is a perspective view showing a schematic structure of a roof outer wall structure in a clean room to which the present invention is applied.

The roof 10 and the outer wall 12 of the clean room of this embodiment are formed by bending a folding plate 16 as shown in FIG.
A plurality of the folded plates 16 are arranged in parallel and joined together to be integrally formed. This folded plate 16 is conventionally used as a roof member. For example, a strip-shaped plated steel plate having a thickness of about 0.6 to 1 mm is formed in a groove shape along the longitudinal direction thereof, and has a flat bottom portion 16a and both side edge portions thereof. Slope part 1 bent up from
6b and. A small hook 16c is provided on the upper end of each of the sloped portions 16b, and a plurality of folding plates 16 are provided.
Folding plates 1 adjacent to each other when the grooves are arranged in parallel with each other.
The six pieces are joined by hook joints in which one small hook 16c is overlapped with the other small hook 16d and bent.

The folding plate 16 is the roof 1 of the clean room.
It has a length that forms 0 and the outer wall 12, and at the boundary position between the roof 10 and the outer wall 12, they form a predetermined angle by radial processing and are bent in an arc shape.

The plurality of folded plates 16 are
H-shaped steel 30 and square steel pipe 32 that form the frame of a clean room
In the state where it is placed on, it is connected by the hook joint described above. At this time, as shown in FIG. 3, a hanging member 34 is provided at a predetermined position of the hook joint portion 18, and by this hanging member 34, the folding plate 16 has a shape substantially the same as that of the folding plate 16 in the frame of the clean room. It is fixed via an eggplant tight frame 36.

An outer peripheral member 24 is provided on the hook joint portion 18 with an aluminum foil tape 20 so as to wrap the small hooks 16c and 16d from the outside, and the gap between the folded plates 16 is sealed.
Is formed.

That is, the roof 10 and the outer wall 12 are formed into a continuous and seamless peripheral surface by radially processing a folding plate 16 made of a strip-shaped single member, and a plurality of folding plates 16 are arranged in parallel. It is sealed with no gap between them. Therefore, it is possible to form a clean room having no gap between the roof 10 and the outer wall 12.

Since the hooked portion 18 between the folded plates 16 is simply sealed with the aluminum foil tape 20, workability is improved,
Since a labor-intensive work such as filling of caulking material as in the past is not required, a clean room having air tightness can be constructed in a short period of time and at low cost. further,
Since the aluminum foil tape 20 is attached so as to wrap the small hooks 16c and 16d from the outside, the operation can be performed while visually checking the attached state, so that the gap can be reliably sealed.

In the above-mentioned embodiment, the hooked portion 18 is sealed with the aluminum foil tape 20, but not limited to the aluminum foil tape, stainless tape, vinyl tape, clean tape or the like may be used. Also, this hook 18
May be sealed with a sealing material 38 as shown in FIG. 5 without using such a tape. In this way, when the hooked portion 18 is sealed from the outside of the clean room with the tape or the sealing material 38, even if gas or the like is generated from the tape or the sealing material 38, the gas does not contaminate the inside of the clean room.

Further, since the clean room is required to have not only the airtightness but also the heat insulating property, the roof outer wall structure of this embodiment has a double structure as shown in FIG.

That is, outside the outer peripheral member 24 formed of the folded plate 16, outer peripheral members 24 formed in the same manner as the folded plate 16 are arranged at intervals. Here, between the outer peripheral members 24 located inside and outside, a saddle 26 serving as a spacing member is provided at an appropriate position, and a sealed space 28 is formed between the outer peripheral members 24. Further, in this space 28, glass wool 22 which is a heat insulating material is provided and held by a well-known glass wool stopper pin 36. At this time, the hooked portion 18 of the outer peripheral member 24 having a double structure does not necessarily need to be provided with a tape or a sealing material.

According to this roof outer wall structure, a double-provided outer peripheral member 24 having no gap makes it possible to realize a clean room having higher airtightness, and a space formed between the outer peripheral members 24. With 28 and the glass wool 22 provided in the space 28, high heat insulation can be ensured.

Further, by simply arranging the glass wool 22 in the space 28, a high heat insulating property can be provided without performing a complicated work such as a conventional spraying work which requires curing. The excellent workability can shorten the construction period and also the construction cost.

[0023]

As described above, according to the present invention,
Since the roof and the outer wall are formed by bending a plate-shaped member, the roof and the outer wall can be reliably closed, and a low-cost roof outer wall structure that can be installed in a short period of time and has high airtightness is realized. be able to.

Further, since a plurality of folded plates are used and the folded plates are connected and sealed with the aluminum foil tape, a higher airtightness can be secured.

Further, a high heat insulating property can be secured only by forming a space between two plate-like members and interposing a heat insulating material between them.
