JPH08303030A - Airtight structure using metallic heat insulating panel for roof and exterior wall - Google Patents

Abstract

PURPOSE: To simplify a structure and easily execute a construction work by using a metallic heat insulating panel for the roof and exterior wall of the building where airtight and heat insulating functions are required for a clean room or the like, and obviating a pressurizing chamber. CONSTITUTION: A heat insulating panel made of a heat insulating material such as hard urethane foam sandwiched with aluminum plates, painted steel plates or the like is used to form the roof 1 and exterior wall 2 of the building where airtight and heat insulating functions are required for a clean room or the like. The connected end of heat insulating panels 1 and 2 is fitted with a joint section of irregular form, hook type or the like, and a packing sheet is attached to the joint section for maintaining airtightness. Then, the air pressurized with a blower 3 is sent to a clean room 5 along an arrow direction via a filter 4 on a ceiling, and drawn into the blower 3 via a suction port 6 formed on a floor, thereby circulating the air. According to this construction, a building does not need to have a double structure, and the clean room 5 can be inexpensively constructed.

Description

Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention relates to the structure of roofs and outer walls in buildings such as clean rooms and fumigation warehouses that require airtightness and heat insulation.

[0002]

2. Description of the Related Art For example, in a clean room, a pressure chamber is provided on the ceiling of the clean room, and pressurized air passes through a filter installed on the ceiling of the clean room. The air is circulated to operate by circulating the air from the suction port narrowed to the blower, but the pressure becomes higher than the external pressure in the pressurizing chamber. Therefore, in order to secure these pressure differences, it must be airtight against the external pressure.

For this reason, conventionally, a pressure chamber separate from the building has been provided in the lower part of the roof and the upper part of the clean room. FIG. 4 is a diagram of a conventionally used clean room. A pressure chamber is provided above the filter 4 installed on the ceiling of the clean room 5 separately from the building, and air is blown into the clean room 5 from the blower 3 via the duct 3a. The pressure chamber and the building have a double structure.

[0004]

The conventional method for providing a separate pressure chamber inside a building has a complicated structure,
Since the construction is also complicated and the cost is high, recently, there is a case where a ceiling in which concrete or concrete is placed on a deck plate is constructed and used as it is as a pressure chamber. However, since it is heavy and the construction is complicated, and when the heat insulating material is applied, it is necessary to wait for the hardening of the concrete to apply the heat insulating material, and further to perform waterproofing, so that the construction period is long and the construction cost is high. Further, in the case of the pressure chamber, there is a problem that the air contained in the fine gaps existing in the concrete bulges to the outer surface.

In a clean room using a recent fan filter unit, a negative pressure is generated in the chamber, but it can be applied to that case as well.

The present invention has been devised to solve these problems.

[0007]

[Means for Solving the Problems] In a structure requiring airtightness and heat insulation, a metal heat insulation panel is used for the roof and the outer wall, and a metal heat insulation panel is used for the roof and the outer wall. The main purpose is the airtight structure used.

[0008]

The operation of the airtight structure using the heat insulating panel made of metal for the roof and the outer wall of the present invention is as follows.

(A) Since the roof and the pressure or negative pressure chamber are not duplicated, the structure is simple.

(B) Compared with the case where a pressure or negative pressure chamber is constructed by using concrete directly on the roof or concrete on the deck plate, the weight is lighter and the structure and construction are simplified. It

(C) By using concrete directly on the roof,
There is no bulging of the waterproof surface due to bulging of air contained in the concrete gap due to pressurization as in the case of configuring the pressurizing chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of an airtight structure using a metal heat insulating panel of the present invention will be shown below with reference to the drawings.

FIG. 1 is a view showing a cross section of an airtight structure of a clean room. The roof of the building is composed of a metal heat insulating panel 1 for roof, and the outer wall is assembled by a metal heat insulating panel 2 for outer wall. The air pressurized by the blower 3 passes through the filter 4 installed on the ceiling of the clean room 5 through the pressure chamber constituted by the roof heat insulating panel 1 along the arrow, passes through the clean room 5, and passes through the clean room 5. Air is circulated by being sucked by the blower 3 from the suction port 6 narrowed in the floor.

FIG. 2 is a sectional view of the metallic heat insulating panel 1 for a roof. For example, on the outer plate 7 such as aluminum plate or painted steel plate,
For example, a heat insulating material 8 such as a rigid polyurethane foam is sandwiched. The metal insulation panel is of suitable size and has fittings 9 at both ends. In addition, packing 10
Hold and seal. FIG. 3 is a cross-sectional view of the outer wall metal heat insulating panel 2, and the reference numerals are the same as those in FIG.
