[0001]

[Industrial applications]

 The present invention relates to a heat insulating material for double floors.

[0002]

[Prior art]

 Conventionally, a double floor with integrated support legs has been used for an OA floor, etc. and must be installed directly on the concrete slab, so there is a space between the double floor and the concrete slab. This space serves as a passageway or a place of habitat for mice, and the mice bite the wiring, causing problems in office automation equipment or damage such as electric leakage and fire. In addition, in the event of a fire, there is a problem that the fire runs through the space and the fireproof partition on the floor is not useful and the fire spreads.

[0003]

[Problems to be solved by the device]

 SUMMARY OF THE INVENTION An object of the present invention is to provide a support leg-integrated double-story heat insulating material composed of a mineral fiber and a resin, which solves the above problems.

[0004]

[Means for Solving the Problems]

 The above-mentioned problem is a space where the legs of the double-floor with integrated support legs can be inserted by making the flat shape of the double-floor with integrated support legs of the present invention a plane shape and the height of the legs of the double-floor with integrated support legs set to be thick. It is solved by a non-combustible double-floor heat insulating material characterized by having 2 to 6 sections. The present invention seals the space other than the wiring part with a heat insulating material made of a mineral fiber in the space that becomes the path of the mouse, the place of habitat or the path of the fire, and makes the space of the wiring part a closed space to allow the mice to enter and exit. It also closes the space that serves as the passage for the fire in the event of a fire.

The non-combustible double-floor heat insulating material of the present invention has a length of about 1 mm to 50 mm and a fiber diameter of about 1 μ to 20 μ, which is made into a fiber by a known manufacturing method using blast furnace slag, basalt or scrap glass as a raw material. Phenolic resin or melamine resin is sprayed onto mineral fibers such as rock wool and glass wool to bond and laminate the fibers, and a 40-200 kg / m ³ laminate molded to a desired thickness is formed into a desired double floor. Cut and mold according to.

The present invention will be described with reference to the drawings based on an embodiment. 1 and 2 show an example of a double floor in a schematic view and a plan view, showing the height of the legs and the position of the legs. 3 and 4 are a plan view and a side view of the heat insulating material for the double floor of the present invention in the case of the double floor shown in FIGS. According to the height of the legs and the position of the legs of the double floor shown in FIGS. 1 and 2, 40 to 200 kg / m ³ of the mineral fiber laminate was cut and molded as shown in FIGS. The double floor insulation of the present invention is obtained.

FIG. 5 is a partial view of one use example of the heat insulating material for double floor of the present invention. In FIG. 5, the insulation material for the double floor, which is divided into four parts in the wiring part, is omitted, but if the wiring is thin, it may not be omitted due to the elasticity of the insulation material.

The double-layered heat insulating material of the present invention is characterized by being divided into 2 to 6, but it is determined by a balance between easy handling and minimizing the space generated for wiring and the like. However, in general, four divisions are suitable for handling, space, and ease of manufacture.

The heat insulating material for a double floor of the present invention is made of mineral fibers such as rock wool and glass wool, which are sprayed with a phenol resin or a melamine resin and bonded and laminated between the fibers. It is used for fire protection. In addition, the heat insulating material obtained by the present invention may be laminated with paint, decorative paper, etc., if necessary.

[0010]

[Action]

 The heat insulation material for the double floor of the present invention uses mineral fibers such as rock wool and glass wool, so it has excellent fire resistance, and is compatible with the double floor mold and the legs of the double floor. The only space is to prevent mice from entering and leaving, and also to prevent fire from running between the double floor and the concrete slab during a fire. In addition, it also has the effect of heat insulation because it can prevent the circulation of air.

[0011]

【Example】

 For the double floor (size 500 × 500 × 20 mm, leg height h = 100 mm) of FIGS. 1 and 2, 250 mm × 250 mm × 100 mm rock wool insulation material (manufactured by Nitto Boseki Co., Ltd.) The heat insulating material of the present invention was obtained by cutting and molding into four parts. FIGS. 3 and 4 show a case where four heat insulating materials are combined and arranged in a shape corresponding to a double floor.

[0012]

[Effect of device]

 The space between the double floor and the concrete slab can be filled with heat insulating material without impairing the advantages such as wiring of the double floor, so there is no space for mice to enter or leave, and no fire will run during a fire.
