DETAILED DESCRIPTION OF THE INVENTION [Industrial Applications 1] The present invention relates to a large heat-insulating, waterproof and anti-vibration mat to be laid on the roof of a reinforced concrete building, and a method for laying the same.

[Jubei technology] There were mats and methods for laying them that had the functions of heat insulation, waterproofing, heat insulation, soundproofing, and vibrationproofing.

However, recently, there has been a demand for roofs of reinforced concrete buildings that have the three functions of heat insulation, waterproofing, and soundproofing/vibration proofing.

In order to meet these demands, as shown in Fig. 6, a first waterproof layer 8 is constructed on the concrete slab 2, and then a buffer mat 9 such as glass wool is laid down.
A polyethylene sheet 10 is laid on top of that, and then a protective mortar 11 is placed, and a second waterproof layer 12 is placed on top of that.
After construction, protective concrete 7 was poured.

[Problem to be solved by the invention] However, the above-mentioned conventional construction requires a large number of man-hours. In addition to many drawbacks, there were also the following drawbacks:

1) Waterproofing for the first and second layers requires approximately two weeks of drying time until the moisture level of the underlying concrete or mortar falls below approximately 5%. It is easily influenced by the weather, which has a large impact on the construction period.

2) There are many types and quantities of materials used, many man-hours, and many types of jobs, which has a large impact on the overall construction process.

3) Asphalt thermal waterproofing etc. causes pollution such as smoke and odor to the surrounding area.

The present invention was made in order to solve the above-mentioned problems, and its purpose is to perform heat insulation, waterproofing, and vibration proofing with a small number of steps, and to adjust the degree of dryness of the base concrete and mortar. To provide a large heat-insulating, waterproof and anti-vibration mat and a method for laying the same, without being a shadow or causing pollution such as smoke or odor to the surrounding area.

[Means for Solving the Problems 1] The large heat-insulating, waterproof and anti-vibration mat of the present invention is made of high-density glass wool, rock wool, various natural/synthetic resin fibers, foamed resin, etc., which have heat insulating properties and appropriate cushioning properties. A plurality of rectangular heat-insulating cushioning materials are arranged at predetermined intervals on a waterproof rubber-based, synthetic resin-based, or rubber-asphalt-based wide and long waterproof sheet, and are made of the same material as the waterproof sheet. It is characterized by being wrapped in a covering waterproof sheet.

Furthermore, the method for laying the large heat-insulating, waterproof and anti-vibration mat of the present invention is to lay the side edges of adjacent wide and long waterproof sheets abutting each other on a concrete slab, and to use the abutted portions for joining. It is characterized in that they are joined by a waterproof sheet, and further characterized in that a groove mat is fitted into the groove portion formed between the heat-insulating and cushioning materials of the laid mat.

The above-mentioned groove mats are made by wrapping a heat-insulating and cushioning material such as high-density glass wool, rock wool, various natural/synthetic resin fibers, or foam resin-based materials with a vinyl chloride or polyethylene sheet. has been done.

Another feature is that a non-woven fabric or synthetic resin molded net is laid on the mat as an insulating protective layer, and protective concrete is placed on top of the non-woven fabric or synthetic resin molded net.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In Figures 1 and 2, 1 is a long mat, which is composed of a heat insulating cushioning material 1a, a wide and long waterproof sheet 1b surrounding it, and a covering waterproof sheet 1c. ing.

The insulation cushioning material 1a is made of one or a combination of materials such as high-density glass wool, rock wool, various natural/synthetic resin fibers, or foamed resin, and has appropriate cushioning properties. It is necessary to have heat insulation properties.

For cushioning properties, the density is 60 to 120 kg/m'
It is preferable that the static and dynamic spring constants per unit area are both about 2.0 to 8.0 (106NlI1'').

In addition, as for the heat insulation property, the thermal conductivity is 0.05 (Kcal
/III・hr・'C) The following are desirable.

The heat insulating buffer material 1a has, for example, 900 mtsX
600■ rectangular, 100-200+n+a
Multiple sheets are arranged at intervals. This interval may be any interval as long as it can secure a folding allowance so that the elongated Masoto 1 can be easily folded and transported.

The wide and long waterproof sheet 1b is made of a rubber-based, rubber-asphalt-based, synthetic resin-based, or other waterproof sheet. The thickness of the wide long waterproof sheet 1b is preferably about 2 mm for economical reasons, and is a wide long sheet configured to extend, for example, about 300 mm on both sides of the heat insulating cushioning material 1a. be.

-L-coated waterproof sheath} 1c is the above-mentioned wide and long waterproof sheath}
The same material as 1b is used, but the thickness may be slightly thinner, about 0.5 to 1 mm.

Both of the above waterproof sheets} 1b and lc do not necessarily have to be excellent in ozone resistance, ultraviolet ray resistance, etc., since protective concrete is placed on the mat 1, and when the protective concrete is placed, it will not break. It is sufficient if the material has a certain tensile strength, tear strength, or alkali resistance.

The covered waterproof sheet 1c is covered with the heat insulating cushioning material 1a, and its peripheral portion is joined to the wide and long waterproof sheet 1b by overlapping. These waterproof sheets}1b. The method of joining 1c differs depending on the type of waterproof sheath 1b. For example, if the waterproof sheet is a vulcanized rubber sheet, an adhesive is applied to the joint surface with a non-vulcanized rubber tape interposed, and heated and rolled using a roller or hot press. If the waterproof sheet is a self-welding type vinyl chloride sheet or a deteriorated bitumen sheet, the surface can be slightly melted by using adhesive or flame, and then it can be joined by self-welding. Alternatively, it can be joined by self-welding. do.

The mat 1 is stored and transported in a compactly folded state as shown in FIG.

Next, a method of laying the mat will be explained.

First, as shown in FIG. 4, a mat 1 is laid on a concrete slab 2. The side edges of the wide and long waterproof sheets 1b of the adjacent mats 1 are butted against each other, and the butt portions are bonded with a joint sheet 2' having a width of approximately 2001III1 using adhesive or the like. Join.

When the laying of the mat 1 is completed, as shown in FIG. 5, the mat 3 for large grooves and the mat 4 for small grooves are respectively fitted into the grooves formed in the openings of the heat insulating cushioning material 1a. These groove mats 3 and 4 are constructed by wrapping the same material as the heat insulating cushioning material 1a in a vinyl chloride or polyethylene sheet approximately 200 microns thick.

Once the groove mats 3 and 4 have been set, an insulating protective layer 5 of nonwoven fabric, synthetic resin molded net, asphalt flat plate, etc. is laid on top of the mats, and then reinforcing bars 6 are placed and protective concrete 7 is laid. Pour concrete. 7a is an expansion joint.

[Effect of the invention 1 (1) Since mats can be laid quickly on young slab concrete regardless of its dryness, interior work on the lower floor can be started early, resulting in significant savings. It is possible to shorten the construction period.

(2) Three functional effects of heat insulation, waterproofing, and cushioning can be obtained with one installation.

(3) Insulation 1/I is laid on the mat before the protective concrete is placed, so it provides protection during the work of placing the protective concrete, prevents concrete from flowing into the gaps between the mats, and prevents the thermal protection of the protective concrete layer. It is possible to effectively deal with movements caused by expansion and contraction.

(4) There is no risk of emitting pollution such as smoke or odor.

(5) There is no risk of fatigue rupture of the waterproof layer due to the movement of cracks in the concrete structure, as is the case with the pasting method.

(6) The matte method of the present invention can be used on rooftops of apartment complexes, floors that serve as playgrounds, simple sports fields, or setback balcony floors, community plazas installed on rooftops and intermediate floors of high-rise housing, and machines such as pump rooms. It can be applied to the floors of rooms, the roofs of school buildings, the floors of restaurant kitchens and air conditioning equipment rooms installed on the roofs and intermediate floors of hotels and office buildings, and the floors of parking areas of complex buildings.
