Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a heat insulating / insulating work heat insulating plate used for construction work of a heat insulating / waterproof layer on a roof of a building or the like.

[Conventional technology]

As conventional heat insulation boards for heat insulation work, there are plate-like ones that are cut to a predetermined size and attached to the work surface one by one at the construction site, and continuously unwound on the work surface during construction. There is a wide and long plate type that is attached in a spiral shape. The plate-shaped material cut into a predetermined size is often made of a relatively hard plate material such as a rigid polyurethane foam, an organic rigid foam material such as rigid polyethylene foam, an inorganic foam material such as foam glass, and the dimension is 605 mm. × 910 m
It's a relatively large plate, although it can be carried around at 457mm x 700mm, 305mm x 457mm, etc. The wide and long plate wound in a spiral shape is made of a hard plate material like the above, and has a width of about 1 m or more and is a wide plate with asphalt roofing bonded to at least one surface as a face material. In the case of a long heat insulating plate that is relatively hard, it is a product that is wound in a spiral shape for convenience of storage, transportation, and construction, and the product is wound at equal intervals in the length direction and is orthogonal to the length axis. Then, a large number of parallel cut lines extending in the width direction are provided.

[Problems to be solved by the device]

The above-mentioned conventional heat-insulating plate that is attached one by one is large and relatively hard as described above, so that if the work surface is not a flat surface, it will not partially adhere even if it is pressed and adhered. Also, some parts do not adhere well. In particular, after heat-insulating and waterproofing, the surface to be repaired after the waterproof layer to be repaired has been peeled off after years of repair, and the surface to be repaired is prominently uneven. The adhesive area of the material is reduced. In any of the above cases, the poor adhesion of the heat insulating plate causes the warping of the heat insulating plate, which is accompanied by the inconvenience of often breaking the waterproof tank attached to the upper surface thereof. Further, when the conventional wide and long spiral heat insulating plate is used, the adhesive such as molten asphalt may be unwound on the surface to be worked, unrolled, and rolled for continuous sticking, Although the workability of attachment is better than that of a type of heat-insulating plate that is attached one by one, the heat-insulating plate that is long in the width direction and is divided into a number of sheets to be attached is extremely long in the width direction. Since it is a plate, since it is a relatively hard plate, adhesion failure in the width direction with respect to the work surface is likely to occur, and therefore there is the inconvenience that problems such as warping and breakage of the waterproof layer accompanying this are inevitable. .

[Means for Solving the Problems]

The present invention eliminates the above-mentioned drawbacks of the conventional large-sized heat insulating plate, fits well to the work surface, provides good adhesion over the entire surface, and maintains good heat insulating property. In addition, it provides an insulation board for insulation and waterproofing work that can be obtained at low cost,
In a heat insulating plate for heat and waterproof construction, comprising a heat insulating plate and a face material integrally laminated on at least one surface of the heat insulating plate, a plurality of parallel cut lines intersecting with each other on the surface to be attached to the work surface of the heat insulating plate. It is formed by engraving a large number of divided surfaces surrounded by.

[Action]

When the insulation board for heat insulation and waterproofing work of the present invention is pressure-bonded to the work surface with an adhesive, the surface to be adhered is preliminarily parallel and several other free movements can be made by intersecting cut lines. Since the dividing surface is engraved, even if there are irregularities on the surface to be constructed, the dividing surface corresponding to each of these surfaces conforms to the construction surface part, so that good adhesion can be achieved over the entire surface. Is obtained and adhesion failure is eliminated.

In addition, since several other dividing surfaces are carved by a large number of parallel and intersecting cutting lines, it is possible to obtain a product having a dividing surface of a certain size arranged regularly and maintaining good heat insulation. Highly efficient, reliable and inexpensive. Further, since the depth of the cut line can be appropriately changed, various products having different degrees of freedom of the dividing surface can be obtained.

In this case, the parallel score lines are carved at equal intervals over the entire surface so that a plurality of intersecting score lines are formed in the length direction and the width direction of the heat insulating plate material. When crossed along the vertical and horizontal directions, a large number of divided planes of square or rectangular grids arranged in the vertical and horizontal directions are obtained.
Further, in particular, when unwinding a spiral long plate, since the dividing planes which are correctly arranged in the vertical and horizontal directions in the unwinding direction and the direction orthogonal thereto are attached to the work surface, it is smooth and favorable. The application can be made evenly over the whole area. Also, in this case, the length of one side of the rectangular dividing surface is about 200 m at maximum.
When it is set to about m, each divided surface has an extremely small area, so the pressing force is likely to act sufficiently on the entire surface, the adaptability of each individual surface to the construction surface is increased, and good adhesion is performed more sufficiently. be able to.

Furthermore, when the depth of each score line is to reach the interface between the heat insulating plate and the face material integrated with the heat insulating material from the surface to be attached to the work surface of the heat insulating material, the movement of each divided surface In addition, the long type heat insulating material for heat insulating and waterproofing work can be wound more smoothly and satisfactorily.

A product in which the heat insulating properties of the heat insulating plate 1 are maintained well can be obtained. In the illustrated embodiment, the present invention has a thickness of 30 mm, a length of 605 mm, and a width of 605 mm.
It is applied to a large heat insulating plate A, which is formed by integrally adhering an asphalt roofing face material 2 having a thickness of 3 mm to a heat insulating plate material 1 having a thickness of 10 mm. Approximately 10 to 2 in the width direction of the cut lines 4,4 ...
Cut lines 4,4 ...

A large number of square-shaped divisional surfaces 3a, 3a ... Are engraved. In this case, the dividing surfaces 3a, 3a having a rectangular shape, a square shape or the like are formed by appropriately selecting an interval between the cut lines 4, 4 extending in the width direction and an interval between the cut lines 4, 4 extending in the length direction. To do so.

In the example shown in the drawing, the surface 3 to be attached is divided into 6 equal parts with a width of 605 mm divided by 5 parallel cut lines 4 at equal intervals, and a length of 910 mm is divided into 8 parallel cut lines 4 at equal intervals. Divide into 9 equal parts and omit
An example of engraving on a large number of divided surfaces 3a of a 100 mm × 100 mm square is shown. Generally, the interval between these score lines 4 and 4 is appropriately selected according to the size of the large size, but the maximum is about 200 mm × 200
The size is preferably limited to about mm, and about 100 mm × 100 mm is particularly preferable. As a result, the adaptability of the entire surface of each divided surface 3a to the work surface can be ensured. These parallel score lines 4,
4 ... does not necessarily have to be parallel to the side of the heat insulating plate 1, and may be a score line inclined with respect to the side.
A diamond-shaped dividing surface may be formed by these intersections.

The cutting depth of each cutting line 4 is selected as desired, whereby the dividing surface 3 having different degrees of freedom according to the depth of the dividing pieces 5, 5 ...
We can obtain various products with a, 3a. The illustrated embodiment preferably extends over the entire thickness of the heat insulating plate 1. That is, it is preferable to reach from the surface 3 to be attached to the interface between the surface material 2 on the surface and the heat insulating plate material 1 that is fixedly bonded to the surface material 2. As a result, a divided surface 3a is obtained which is cut over the entire length of the heat insulating material 1 and is deeply separated from each other and has the maximum freedom of movement. The divided surface 3a has the best adaptability during pressing. Become.

However, if a sufficient degree of freedom is sufficient for the dividing surface 3a,
Needless to say, the depth of the cut line 4 can be set to an appropriate depth that does not reach the interface.

A large number of the above-described heat insulating and heat insulating boards A of the present invention are prepared at the construction site, and one sheet is prepared by a conventional method on the surface to be constructed such as a concrete foundation through the surface coated with the adhesive such as molten asphalt. After laying one by one and laminating them one after another, the waterproofing work is completed by forming at least one waterproof layer such as asphalt roofing on the upper surface. Is the surface to be attached to the work surface in advance.
Since it is engraved on a, 3a ..., even if the underlying surface is not flat, it is a divided surface 3a, 3 that can move independently and independently.
By a, the surface is finely adapted to face and face each other, so that the attachment is performed well, and the partial defective adhesion that occurs with the conventional heat insulating plate is eliminated. Further, since the facing surfaces of the adjacent split pieces 5, 5 are in contact with each other, good heat resistance can be imparted to the work surface.

3 and 4 show another embodiment, in which the heat insulating plate 1
The present invention is applied to a heat insulating plate A for heat and waterproof construction in which a face material 6 is integrally provided on a back surface 3 to be attached to the surface to be constructed. The face material 6 provided on the back surface is generally made of a glass fiber nonwoven fabric, a synthetic fiber nonwoven fabric, or a core material such as a paper sheet impregnated with asphalt. As one of the production examples, in order to obtain a product of a heat insulating plate material 1 in which both sides of a rigid urethane foam are coated with face materials 2 and 6, a polyisocyanate, a polyol and a catalyst are provided between two long top and bottom face materials. It is obtained by a continuous production method in which a mixed liquid of a foam material is supplied and the foam is heated to form a foam.

Thus, in this embodiment, in the heat insulating and waterproofing work heat insulating plate A, the face material 6 formed on the back surface of the heat insulating plate material 1 becomes the surface 3 to be attached to the work surface. In this embodiment, the spacing between the score lines 4 and 4 extending in the length direction, which are provided in parallel at equal intervals, is set so that the score lines 4 extending in the width direction and provided in parallel at equal intervals. Smaller than the interval of 4,
As a result, a large number of rectangular divided surfaces 3a, 3a ... Are engraved.

More specifically, in the disclosed example, the width 605 mm of the surface 3 to be attached is divided into 12 equal parts by the 11 cut lines 4 in the same large-sized heat insulating and waterproofing board A for heat insulating and waterproofing work as in the above-mentioned embodiment, and the result is , About 5
It was engraved on each of the 0 mm × 100 mm rectangular divided surfaces 3a, and was formed into a surface having a finer adaptability to the work surface.
FIG. 5 is a plan view of a concrete rooftop of an uneven building using a large number of heat insulating boards A for heat insulating and waterproofing work of the present invention, which are attached one by one through a molten asphalt adhesive coated surface C. , An example in which an asphalt waterproof layer D is laminated and pressure-bonded with a desired layer to perform heat insulating and waterproofing work. In this case, even if the work surface has a concave surface as shown in FIG. Each divided surface 3a formed on the surface 3a to be adhered of the heat insulating plate A individually conforms to the concave surface portion so that good adhesion can be performed without a gap therebetween.

FIG. 6 shows still another embodiment of the present invention, which is applied to a wide and long heat insulating plate for heat and waterproof construction. In this embodiment, from the face material 6 of the wide and long plate A, which is composed of the wide and long foamed heat insulating plate material 1 made of a hard polyurethane foam having a thickness of 25 mm and the face materials 2 and 6 integrally provided on both surfaces thereof. On the surface 3 to be adhered to the surface to be constructed, a plurality of parallel pieces extending over the entire thickness of the face material 6 and the heat insulating plate material 1 and extending over the entire width thereof at regular intervals in the length direction. Are provided, and a plurality of parallel cut lines 4, 4 ... that extend along the entire length thereof with a constant interval in the width direction are provided. 4, 4 and 4 are directly applied, and a number of rectangular dividing surfaces 3a, 3a, which are surrounded by the intersecting cut lines 4, 4, are formed. The distance between the score lines is preferably in the range of 50 to 100 mm. A plurality of parallel cut lines extending in the width direction, which are carved at regular intervals in the length direction of the long plate, are carved by the rotation of the traveling rotary blade. The plurality of parallel cut lines extending in the length direction, which are formed at regular intervals in the width direction, are formed by a fixed rotary blade. That is, for example, the traveling rotary blade uses a blade interval set to an interval of 50 to 100 mm, the fixed rotary blade uses a blade interval set to an interval of 100 to 200 mm. Is used to obtain a rectangular dividing surface 3a composed of a large number of rectangular parallelepiped dividing pieces 5, and thus a predetermined product can be obtained easily and quickly with certainty, and mass production can be performed efficiently and inexpensively.

In the illustrated example, the distance between the cut lines 4 and 4 parallel to each other in the length direction of the long plate is 50 mm, and the distance between the cut lines 4 and 4 parallel to each other in the width direction is parallel. The spacing was 100 mm, and each split surface had approximately 50 mm x 100 mm.

Thus, in the wide and long heat insulating plate A of the present invention, the split pieces 5, 5 ... Having the split surfaces 3a, 3a ... Of the same shape and the same size are integrally formed on the face material 2 on the surface thereof over the entire length thereof. Obtained as a long product in a state of being connected and held. Thus, as shown in FIG. 6, it can be well wound in a spiral shape for storage and transportation, and at the time of heat insulation and waterproofing, it is unwound from one end at the construction site as shown in FIG. 7 and melted on the work surface. The asphalt adhesive or the like can be continuously applied and laid down. At this time, the surface 3 to be applied is finely divided into separate divided surfaces 3a, 3a ... As a result, since it is possible to adapt to the uneven surface of the work surface, it is possible to obtain a good sticking work that is evenly and well adhered over the entire width and length.

Thus, by laminating and sticking a waterproof layer such as asphalt roofing on the upper surface by a conventional method, it is possible to maintain a stable and favorable waterproof heat insulating construction layer without peeling or warping of the heat insulating plate A for a long period of time. .

If necessary, the face material 2 on the surface has one side edge portion in the lengthwise direction formed by extending a polymerization bonding margin that is projected outward from the side surface of the heat insulating material 1 on the lower surface. May be. In this case, at the time of the construction, the overlapped adhesion margin is superposed on the upper surface of one side edge of the face material of the heat insulating plate which is adhered adjacently, and the joint is subjected to molten asphalt to obtain a good seal portion. To help.

As a result of various examinations, in order to obtain a uniform and good entire surface attachment, the size of each divided surface 3a formed on the surface 3 to be attached of the heat insulating plate A of the present invention is about 200 or less per side at maximum. Those having a small area are particularly preferable.

[Effect of device]

As described above, according to the present invention, a face material is provided on at least one surface of the heat insulating plate, and a large number of parallel cut lines are made to intersect with each other on the surface to be attached to the work surface of the heat insulating plate. Since it is engraved on a large number of dividing surfaces that are surrounded by intersecting cutting lines, a large number of independent dividing pieces that can move freely to face each part of the work surface are formed uniformly in a regular manner. The obtained heat insulating and waterproofing insulating plate is easily, quickly and surely obtained, and has the effect of enabling mass production of highly efficient and inexpensive products. In addition, since the cutting depth of the cutting line can be adjusted appropriately, it is possible to produce various products having different degrees of freedom in the dividing surface. Thus, when using this heat insulating plate and adhering to a desired work surface, it is possible to adapt and adhere to each of the divided surfaces of each divided piece in accordance with the shape of the work surface. Such partial adhesion failure of the heat insulating plate can be eliminated and good adhesion can be achieved over the entire surface to be worked. Therefore, after waterproofing the upper surface, the heat insulating plate is partially peeled off. , There is no warp,
As a result, there is an effect such that a waterproof adiabatic construction can be obtained in which a certain water tank after construction has a long life without breakage and the heat insulation property is excellently maintained.

Moreover, since these divided pieces are formed by the score lines, the facing surfaces of the divided pieces can be applied to the work surface in a state of being in contact with each other, so that the heat insulating plate material is good against the work surface. It has the effect of imparting excellent heat insulating properties.

In this case, each division surface is a square and the length of one side is about 200 m.
When the length is m or less, the area is small, the conformability is good over the entire surface of the work surface at the time of pressing and sticking, and particularly in the case of a square shape, uniform sticking can be obtained very well, and a large number of intersecting strips can be obtained. When the depth of is equal to the entire thickness of the heat insulating material, there is an effect that the flexibility of the divided piece is maximized.
