Description

The present invention relates to a heat insulating and waterproof structure having a plurality of heat insulating materials laid on a base such as a building and a waterproof sheet laid on the heat insulating material, a heat insulating tool used for the heat insulating and waterproof structure, and heat insulating waterproof. Regarding the heat insulation and waterproof construction method for laying the structure.

A foaming material is used as a heat insulating material in a heat insulating and waterproof structure on the roof of a building or the like. Foaming materials include soft foaming materials such as polyethylene and hard foaming materials such as polystyrene and polyurethane, but in the case of a heat insulating and waterproof structure on the roof, it is possible to walk on the waterproof sheet laid on the heat insulating material. Since it is required, a hard foaming material is used. Conventionally, a heat insulating material made of a hard foaming material such as polystyrene or polyurethane has been fixed to a base by using an anchor member. Specifically, the heat insulating material is mechanically (physically) fixed to the base by driving an anchor member through which the heat insulating material is penetrated into the base.

However, with such mechanical fixing means, noise and vibration are inevitably generated because there is a work of drilling a hole in the concrete as a base. In the case of renovation work, people live in the building, which is a big problem.

In addition, usually, the number of heat insulating materials to be laid on the base is prepared according to the area of the base and spread so as not to create a gap, but in most cases, the base has unevenness. However, when a hard foaming material is used as the heat insulating material, when a plurality of heat insulating materials are arranged on a ground surface, a step is generated between the adjacent heat insulating materials. If there is a step between the heat insulating materials arranged on the base, when the waterproof sheet is laid on the step, the step between the adjacent heat insulating materials appears on the surface of the waterproof sheet, and the appearance is deteriorated.

In Patent Document 1, in order to prevent a step from appearing on the surface of the waterproof sheet due to the unevenness of the base, a slope member is arranged so as to straddle two adjacent heat insulating materials, and the slope member and heat insulating material are arranged. A tarpaulin is laid on the material.

However, in the heat insulating and waterproof structure of Patent Document 1, although the step on the surface of the waterproof sheet is improved, the heat insulating material is fixed to the base by the conventional fixing method in which the anchor member is driven. , The problem of vibration has not been solved.

Therefore, the present invention is used for a heat insulating and waterproof structure that can be constructed without making a hole in the base and that can suppress a step on the surface of the waterproof sheet even if the base is uneven, and a heat insulating and waterproof structure thereof. It is an object of the present invention to provide a heat insulating tool and a heat insulating and waterproofing method for constructing the heat insulating and waterproof structure.

A head that is inserted into the through hole from the side opposite to the lower plate and has a diameter larger than the diameter of the through hole, and is located on the lower plate side of the head and smaller than the diameter of the through hole. It has a diameter and has a shaft portion that is screwed into the lower plate and is connected to the lower plate. By providing a convex portion on the surface of the lower plate on the base side, the lower plate and the base are provided. A gap is formed between the shaft portion and the shaft portion, and the shaft portion penetrates the lower plate and extends to a gap between the lower plate and the base plate .

According to this configuration, the upper plate and the lower plate of the heat insulating tool are arranged so as to sandwich the abutted ends of two adjacent heat insulating materials.

Therefore, the lower plate and / and the upper plate and the plurality of protrusions connect the two adjacent heat insulating materials. Since the plurality of heat insulating materials are integrated in this way, it is possible to prevent the heat insulating material from being misaligned without fixing the heat insulating material to the base. Therefore, the heat insulating and waterproof structure can be constructed without making a hole in the base.

Since the upper plate and the lower plate can be easily connected by the connecting member in this way, the construction work can be reduced.
Further, from the viewpoint of fixing the lower plate to the shaft portion, it is preferable that the shaft portion penetrates the lower plate. However, when the surface of the portion of the base that overlaps the lower plate is flat, the gap between the lower plate and the base is small. Therefore, even if the heat insulating tool is configured so that the shaft portion penetrates the lower plate, the shaft portion may come into contact with the base and the shaft portion may not penetrate the lower plate. On the other hand, in the present invention, since the convex portion is provided on the surface of the lower plate on the base side, even when the surface of the portion overlapping the lower plate of the base is flat, the space between the lower plate and the base is formed. A gap is formed in the portion overlapping the shaft portion. Thereby, the heat insulating tool can be configured so that the shaft portion penetrates the lower plate.

It is a top view which shows the state before laying the waterproof sheet of the heat insulation waterproof structure shown in FIG. It is sectional drawing of the heat insulation waterproof structure which concerns on 2nd Embodiment of this invention. It is a top view which shows the state before laying the waterproof sheet of the heat insulating spinning structure shown in FIG.

Hereinafter, the first embodiment of the present invention will be described.
FIG. 1 is a cross-sectional view of the heat insulating and waterproof structure 1 of the first embodiment. The heat insulating and waterproof structure 1 is provided on a base 100 such as the roof of a building. The base 100 is made of, for example, concrete. As shown in FIG. 1, the surface of the base 100 may have unevenness (unevenness). The heat insulating and waterproof structure 1 has a plurality of heat insulating materials 2, a plurality of heat insulating tools 3, and a waterproof sheet 8.

The plurality of heat insulating materials 2 are laid on the base 100. As shown in FIG. 2, the heat insulating material 2 has a square plate shape (a plate shape having a quadrangular view in a plan view). Note that FIG. 2 is a plan view showing a state before laying the waterproof sheet 8 of the heat insulating waterproof structure 1 of FIG. The plurality of heat insulating materials 2 are arranged so that the boundaries are in a grid pattern. The length of the short side of the heat insulating material 2 is, for example, 500 to 1000 mm, and in that case, the length of the long side is, for example, 800 to 1300 mm. The heat insulating material 2 may be square. The thickness of the heat insulating material 2 is, for example, 20 to 200 mm. The material of the heat insulating material 2 is, for example, rigid polyurethane foam, rigid polystyrene foam, phenol foam, or the like. Phenolic foam has better heat insulation performance than rigid polyurethane foam and rigid polystyrene foam. While many plastics melt when exposed to heat, phenolic resins are heat resistant and cure with heat. Rigid polyurethane foam has a structure in which a gas having extremely low thermal conductivity is confined in independent fine bubbles, and therefore has higher heat insulating performance than rigid polystyrene foam. The higher the heat insulating performance of the material of the heat insulating material 2, the thinner the thickness of the heat insulating material 2 can be. The heat insulating material 2 is preferably adhered to the base 100 with a first adhesive (not shown). As the first adhesive, for example, an adhesive that does not use an organic solvent such as a polyurethane-based adhesive or a modified silicon-based adhesive is used.

More specifically, each heat insulating tool 3 connects four heat insulating materials 2 arranged so as to form a cross at the boundary. It is preferable that the heat insulating tool 3 is arranged at all the positions where the boundaries of the plurality of heat insulating materials 2 intersect. Each heat insulating tool 3 has a lower plate 4, a plurality of protrusions 5, an upper plate 6, and a connecting member 7.

The lower plate 4 is arranged between the abutted ends of the two adjacent heat insulating materials 2 and the base 100. More specifically, the lower plate 4 is arranged between the abutted corners of the four heat insulating materials 2 arranged so that the boundaries form a cross and the base 100. The thickness of the lower plate 4 is, for example, 2 to 5 mm. The lower plate 4 has a square shape in a plan view and has a side length of, for example, 100 to 200 mm. The shape of the lower plate 4 may be a shape other than a square shape such as a rectangular shape or a circular shape.

As shown in FIG. 1, the plurality of protrusions 5 are provided on the lower plate 4. As shown in FIG. 2, four protrusions 5 are provided on one lower plate 4. The four protrusions 5 are arranged so as to be located at the four vertices of the square. The tip of the protrusion 5 is tapered and pointed. The four protrusions 5 are inserted into the corners of the four heat insulating materials 2 arranged so that the boundaries form a cross. Therefore, the four heat insulating materials 2 are connected via one lower plate 4 and four protrusions 5. The protrusion 5 does not penetrate the heat insulating material 2. That is, the length of the protrusion 5 is shorter than the thickness of the heat insulating material 2. When the thickness of the heat insulating material 2 is the above-mentioned thickness, the length of the protrusion 5 is, for example, 15 to 30 mm. The diameter of the protrusion 5 is, for example, 8 to 12 mm. The protrusion 5 is preferably made of the same material as the lower plate 4.

The top plate 6 is placed on the abutted ends of two adjacent insulations 2. More specifically, the upper plate 6 is arranged so that the abutting corners of the four heat insulating materials 2 arranged so as to form a cross boundary are sandwiched between the upper plate 6 and the lower plate 4. Will be done. A through hole 6a is formed in the central portion of the upper plate 6. The upper plate 6 has a circular shape in a plan view, and its diameter is, for example, 65 to 100 mm. The shape of the upper plate 6 may be a shape other than a circular shape such as a square shape or a rectangular shape.

The connecting member 7 connects the lower plate 4 and the upper plate 6. The connecting member 7 is arranged between the abutted ends of two adjacent heat insulating materials 2. More specifically, the connecting member 7 is arranged between the abutted corners of the four insulating materials 2 arranged so that the boundaries form a cross. The connecting member 7 is a screw. The connecting member 7 has a head portion 7a and a shaft portion 7b in which a thread groove is formed. The diameter of the head portion 7a is larger than the minimum diameter of the through hole 6a of the upper plate 6. The diameter of the shaft portion 7b is smaller than the minimum diameter of the through hole 6a of the upper plate 6. The connecting member 7 is inserted into the through hole 6a of the upper plate 6 from above. The head portion 7a of the connecting member 7 is locked to the upper plate 6. The shaft portion 7b of the connecting member 7 is connected to the lower plate 4 in a state of being screwed into the lower plate 4. The shaft portion 7b of the connecting member 7 preferably penetrates the lower plate 4, but may not penetrate. The connecting member 7 is not driven into the base 100. The connecting member 7 may be a so-called tapping screw, or may be a so-called self-drill screw in which the tip end portion of the shaft portion 7b is formed in a drill shape. A pilot hole may be formed in the lower plate 4 in advance, but when the connecting member 7 is a tapping screw, the connecting member 7 can penetrate the lower plate 4 without making a pilot hole. By screwing the connecting member 7 into the lower plate 4, a screw thread is formed on the lower plate 4, so that the connecting member 7 can be screwed and fixed to the lower plate 4. The diameter of the shaft portion 7b of the connecting member 7 is, for example, 3 to 8 mm. The length of the shaft portion 7b of the connecting member 7 in the longitudinal direction is equal to or greater than the thickness of the heat insulating material 2. When the thickness of the heat insulating material 2 is the above-mentioned thickness, the length of the shaft portion 7b of the connecting member 7 in the longitudinal direction is, for example, 20 to 210 mm. When the shaft portion 7b penetrates the lower plate 4, the shaft portion 7b preferably protrudes by at least 1 mm or more from the lower surface of the lower plate 4, and more preferably by about 5 mm.

As shown in FIG. 1, the waterproof sheet 8 is laid on a plurality of heat insulating materials 2 and a plurality of upper plates 6. The waterproof sheet 8 has flexibility. The material of the waterproof sheet 8 is EPDM (ethylene / propylene / diene copolymer), IIR (butyl rubber), NR (natural rubber), SBR (styrene / butadiene rubber), CR (chloroprene rubber), NBR (acrylonitrile / butadiene rubber). ), HNBR (hydrogenated acrylonitrile-butadiene rubber), CSM (chlorosulphonized polyethylene) and the like, and may be a thermoplastic elastomer, polyethylene, polypropylene, polyvinyl chloride and other synthetic resins. Although it depends on the area of the construction site, the waterproof sheet 8 may be one integrally molded sheet or may be a plurality of integrally molded sheets bonded together. The thickness of the waterproof sheet 8 is preferably 1.0 to 2.5 mm. If the thickness is less than 1.0 mm, the strength may be insufficient and the waterproof sheet 8 may be easily broken. On the other hand, if the thickness exceeds 2.5 mm, a step becomes large at the joint portion when the sheets are connected, which may deteriorate the appearance, which is not preferable. Further, as the waterproof sheet 8, a sheet made of the above-mentioned rubber or synthetic resin is embedded with a reinforcing cloth made of glass fiber, polyester fiber or the like to improve mechanical strength or dimensional stability. You may. The waterproof sheet 8 is adhered to the heat insulating material 2 by a second adhesive (not shown). As the second adhesive, for example, an adhesive containing chloroprene rubber, butyl rubber, or the like is used. When the heat insulating material 2 is other than polystyrene foam, a solvent-based adhesive using an inorganic solvent as a solvent can be used as the second adhesive. Further, regardless of the material of the heat insulating material 2, as the second adhesive, a water-based adhesive using water as a solvent or a solvent-free adhesive that is cured by a chemical reaction without using a solvent can be used.

Next, the heat insulating and waterproofing method for laying the heat insulating and waterproof structure will be described.

(Lower plate placement process)
First, the layout of the plurality of heat insulating materials 2 arranged on the base 100 is determined. Then, the lower plate 4 is temporarily arranged at a position where the corner portions of the four heat insulating materials 2 are abutted and arranged on the base 100.

(Insulation material placement process)
The first adhesive is partially applied to the heat insulating material 2. When the unevenness of the base 100 is large, the first adhesive is applied to the concave portion of the base 100, or a large amount of the first adhesive is applied to the portion of the heat insulating material 2 arranged on the concave portion. Next, the four protrusions 5 provided on one lower plate 4 are inserted into the corners of the four heat insulating materials 2, and the corners of the four heat insulating materials 2 are arranged on the lower plate 4. To do. Then, the heat insulating material 2 is pressed against the base 100 and adhered to the base 100.

(Top plate placement process)
Next, the upper plate 6 is arranged on the abutted corners of the four heat insulating materials 2.

(Connecting process)
Subsequently, the connecting member 7 is inserted between the through hole 6a of the upper plate 6 and the abutted corners of the four heat insulating materials 2. Then, the connecting member 7 is screwed into the lower plate 4 by a driver and connected to the lower plate 4.

In the same procedure, the remaining heat insulating material 2 and the heat insulating tool 3 are arranged. After arranging all the lower plates 4 and all the heat insulating materials 2 on the base 100, the upper plate 6 and the connecting member 7 may be arranged.

(Waterproof sheet placement process)
Next, the second adhesive is applied to the entire upper surface of the plurality of heat insulating materials 2 and the upper surface of the plurality of upper plates 6 using a roller brush, a hand brush, or the like. Subsequently, the waterproof sheet 8 is arranged on the plurality of heat insulating materials 2 and the plurality of upper plates 6 and rolled and bonded.

The heat insulating and waterproof structure 1, the heat insulating tool 3, and the heat insulating and waterproofing method of the first embodiment have been described above.
According to the first embodiment, the upper plate 6 and the lower plate 4 of the heat insulating tool 3 are arranged so as to sandwich the abutted ends of the two adjacent heat insulating materials 2. Further, a plurality of protrusions 5 are provided on at least one of the upper plate 6 and the lower plate 4, and the plurality of protrusions 5 are provided on two heat insulating materials 2 arranged between the upper plate 6 and the lower plate 4, respectively. One or more are plugged in. Therefore, the lower plate 4 and / and the upper plate 6 and the plurality of protrusions 5 connect the two adjacent heat insulating materials 2. Since the plurality of heat insulating materials 2 are integrated in this way, it is possible to prevent the heat insulating material 2 from being displaced without fixing the heat insulating material 2 to the base 100. Therefore, the heat insulating and waterproof structure can be constructed without making a hole in the base 100.

Further, the upper plate 6 is arranged on the abutted ends of two adjacent heat insulating materials 2. Therefore, even if the base 100 is uneven, no step is generated in the portion of the waterproof sheet 8 arranged on the upper plate 6. Further, the abutted ends of the two adjacent heat insulating materials 2 are sandwiched between the upper plate 6 and the lower plate 4 connected by the connecting member 7. Therefore, even if the base 100 is uneven, it is possible to reduce the step between the abutted ends of the adjacent heat insulating materials 2 between the upper plate 6 and the lower plate 4. As a result, even if a part of the abutted ends of the adjacent heat insulating materials 2 is not covered with the upper plate 6, it is possible to prevent a step from being generated in that part. Therefore, it is possible to prevent a step from being generated on the surface of the waterproof sheet 8.

Before arranging the upper plate 6 on the heat insulating material 2, the heat insulating material 2 is arranged on the lower plate 4 arranged on the base 100. A plurality of protrusions 5 are provided on the lower plate 4. Therefore, at this time, since the protrusion 5 provided on the lower plate 4 is inserted into the heat insulating material 2, it is possible to prevent the lower plate 4 from being displaced with respect to the heat insulating material 2. Therefore, construction is easy.

The heat insulating tool 3 connects four heat insulating materials 2 arranged so as to form a cross-shaped boundary. Four heat insulating materials 2 can be connected by one heat insulating tool 3. Since a plurality of heat insulating materials 2 can be connected by a small number of heat insulating tools 3, the construction work can be reduced.

The connecting member 7 connecting the upper plate 6 and the lower plate 4 is arranged between the abutted ends of the two heat insulating materials 2. Therefore, even if there is only one connecting member 7 that connects the lower plate 4 and the upper plate 6, between the upper plate 6 and the lower plate 4 so that the force is evenly applied to the two adjacent heat insulating materials 2. Two heat insulating materials 2 can be sandwiched.
More specifically, the connecting member 7 connecting the upper plate 6 and the lower plate 4 is arranged between the abutted corners of the four heat insulating materials 2. Therefore, even if there is only one connecting member 7 that connects the lower plate 4 and the upper plate 6, there are four connecting members between the upper plate 6 and the lower plate 4 so that the force is evenly applied to the four heat insulating materials 2. The heat insulating material 2 can be sandwiched. Since the number of connecting members 7 can be reduced, the construction work can be further reduced.
