Description

  The present invention relates to a roof or wall repair spray construction structure.

  Traditionally, roofs or walls of factories, warehouses, gymnasiums, etc. have been constructed by corrugated slate, or metal folded plates, tiles, concrete, mortar, etc. There has been a need for periodic repairs for damage to occur, rain leaks from attachments and damages, loss of aesthetics, or enhancement of thermal insulation.

In particular, in the case of a slate thatched roof, its strength is significantly reduced, and when an operator gets on it for repair work, the degraded slate breaks frequently and crashes occur frequently. Screamed by the Ministry of Labor and the Ministry of Land, Infrastructure and Transport, it is still an important issue of occupational accidents in the construction industry.
In addition, the conventional slate structure contains carcinogenic asbestos, and dust is scattered to the surroundings and workers during repair, and it is widely taken up as an environmental problem due to difficulty in processing waste materials. . In addition, in recent years, in order to prevent global warming, repairs to improve the heat insulation performance of these old structures and to save energy in air conditioning are becoming increasingly necessary.

Conventional examples to solve these problems have also been proposed, but none of them emphasized strength at the time of repair or after repair, and did not prevent the above-described crash prevention disaster. .
In addition, regarding waterproofness, if cracks occur in the top coat layer on the surface due to secular change, rainwater enters the fine pores of the heat insulation foam layer, and cracks and alterations occur due to freezing, etc. Was supposed to destroy.

  As an example, there is “JP-A-7-166655”. However, as described above, attention is not paid to prevention of falling due to deterioration of the strength of the substrate, so that the reinforcement strength when the operator gets on is secured. Therefore, there was no fall disaster prevention measure due to strength deterioration for that purpose, and the problem was not actually solved.

Furthermore, since the top coat layer on the surface is a paint curtain layer, it is difficult to have a sufficient curtain thickness. On the other hand, deterioration due to sunlight such as ultraviolet rays, rain, snow, etc., aging Always occurs and cracks occur in the topcoat layer. If that happens, rainwater will enter the fine holes in the heat-insulating foam layer from the cracks, and cracks and alterations may occur due to freezing, etc., destroying the heat-insulating foam layer, and returning the water to the heat-insulating foam layer may hinder safety. However, it has not been a solution to these problems, and improvements were strongly desired.
JP-A-7-166655

  As described above, the present invention provides a repair structure that solves the problems associated with roof and / or wall repair.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention. Details will be described below with reference to the drawings.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a structure after construction in the construction process order, and FIG. 2 is a cross-sectional view perpendicular to the corrugation of the substrate.
Explaining the overall schematic process and structure, a non-metallic material such as slate, concrete, a waterproof sheet, a wooden material, or a base material 1 of a roof or wall of a metal building is fixed to a supporting beam 2. .
A heat insulating foam layer 3 made of a resin foam material such as polyurethane is sprayed on the surface of the substrate 1.

  Next, a reinforced waterproof layer 4 made of a high-strength resin such as polyurethane having quick drying properties and ductility is sprayed on the surface of the heat insulating foam layer 3.

  Next, the surface of the reinforced waterproof layer 4 is a surface layer of one or a plurality of layers by any one of solar resistance such as ultraviolet light resistance, fire resistance, jumping fire resistance, and heat insulation, or a combination thereof. 5 is applied or sprayed.

Next, details of each process and structure will be described.
The heat-insulating foam layer 3 is a material composed of a foamed resin material such as polyurethane, and usually a main agent such as isocyanate and urethane prepolymer and a curing agent such as polyol and polyamine are mixed at a mixing ratio of approximately 1: 1. Mix and foam, add fillers, additives, etc., and spray with a special optimum nozzle sprayer.
In particular, in order to enhance the effect of the present invention, the heat insulating foamed layer 3 can be prevented from entering moisture and can be improved in heat insulation properties by using independent pores.

The heat insulating foam layer 3 has a density of 20 to 70 kg / m ³ , a compressive strength of ³ to 5 kgf / cm ² , exhibits strength in 10 to 60 seconds after spraying, and has a certain reinforcing effect. is doing.
Further, since the thermal conductivity is as small as 0.015 to 0.025 W / mK, extremely high heat insulation can be exhibited.
The thickness of the heat insulating foam layer 3 is desirably about a minimum of 5.0 mm to a maximum of 100 mm.
This is because at 5.0 mm or less, waterproofness and heat insulation performance are insufficient and the effect cannot be exhibited. Moreover, when it is 100 mm or more, the weight becomes heavy, and an excessive load is applied to the substrate 1, and the construction cost becomes high.
More desirably, it is 10 mm to 50 mm.

As described above, since the thickness can be taken sufficiently, it has advantages of high heat insulation, high waterproofness, and high soundproofing.
Moreover, since the base material 1 can be seamlessly coated by spraying, asbestos, which is a carcinogenic substance, can be contained from being scattered, and no waste material of asbestos is generated. The same applies to the reinforced waterproof layer 4.
In addition, since the curtain thickness can be freely adjusted because it is a spray construction, for example, as shown in FIGS. 8, the edge part side surface of the base material 1 and / or the edge part side surface of the heat insulation foam layer 3 can be covered, and discontinuous parts, such as a connection part, can be covered seamlessly. The same applies to the reinforced waterproof layer 4.
Moreover, since the heat insulation foaming layer 3 has cushioning properties, even if the flying object by a typhoon or a strong wind hits a roof directly, it can absorb an impact and can prevent damage. The same applies to the reinforced waterproof layer 4.
In addition, since a flame retardant can be added, it conforms to the performance evaluation standards of flame retardant materials specified in Article 1, Item 6 of the Building Standards Act Construction Order, and the flame retardant third grade test specified in JIS A1321, even for fire. It has flame resistance.
Moreover, since it is an instantaneous curing type, the construction time is short and the work can be performed efficiently.
Further, in consideration of the generation of odors and the environment, no organic solvent such as toluene or xylene can be added.
In addition, since no chlorofluorocarbon gas is used, the ozone depletion coefficient can be made ◯. The same applies to the reinforced waterproof layer 4.

Next, the reinforcing waterproof layer 4 will be described. This layer is the layer that exhibits the features of the present invention most.
As an example, the material is usually mixed with a main component such as isocyanate and urethane prepolymer and a curing agent such as polyol and polyamine at a mixing ratio of about 1: 1, and a filler, an additive, etc. are added. The spraying work is performed by using a special nozzle spray machine with an optimal special nozzle.
In FIG. 3, the result of the physical-property measurement according to JIS A-6021 "paint coating waterproofing agent for buildings" which is an example of the experimental data of the reinforced waterproof layer 4 is shown.
In the tensile properties at break shown in this data, the tensile strength is 2.3 N / mm ² , and the reinforced waterproof layer 4 of the structure of the present invention has a significant strength of 18.0 N / mm ^2. Yes. The elongation at break is 480% against the standard value of 450% or more.
The tensile properties after the deterioration treatment are all conforming to the standard values, indicating that they are not easily deteriorated.
However, the reinforced waterproof layer 4 in the present invention includes the range of this data, and is not limited to this data.
Accordingly, the tensile strength reinforcement waterproof layer 4 in the present invention has a minimum 10.0 N / mm ² ~ up 50.0N / mm ² or less of a high strength.
This is because the reinforcing effect is insufficient at 10.0 N / mm ² or less. Further, the reason why the maximum value is 50.0 N / mm ² is that, in terms of strength, it is not necessary any more than the load of the operator, and the cost is high.
Further, the reinforced waterproof layer 4 in the present invention can exhibit high waterproofness as well as high strength by spraying at a minimum thickness of 0.5 mm or more to 10 mm or less.

The reinforced waterproof layer 4 is a material that is quick-drying, has high strength, and is extensible. Therefore, the worker can get on it for 2.0-15 seconds after spraying, and it is a highly safe construction method, preventing all the stepping-on accidents due to the slate breakage during the above repair work It is possible to demonstrate innovative features.
The reinforced waterproof layer 4 has extensibility, and as shown in FIG. 3, the elongation at break is 480%, and the reinforced waterproof layer 4 is damaged even if the substrate 1 such as a slate breaks. You can follow without.
However, the reinforced waterproof layer 4 in the present invention includes the range of this data, and is not limited to this data.
Therefore, the elongation percentage of the reinforced waterproof layer 4 in the present invention can exhibit a minimum of 400% to a maximum of 800%.
This is because the heat insulating foam layer 3 exhibits a great feature of reinforcing weak points that are difficult to prevent from being damaged. This is also a point that exhibits a large performance difference that is not in the structure of the cited patent document.

Moreover, since the thermal conductivity is as small as 0.015 to 0.025 W / mK, extremely high heat insulation can be exhibited. Therefore, the energy saving effect can reduce the heating and cooling costs, and can contribute to the prevention of global warming.
Moreover, high heat insulation can also exhibit the dew condensation prevention effect by raising the inner surface temperature of the base 1 in winter.
Next, as for waterproof performance, when the reinforced waterproof layer 4 is not provided, the guaranteed lifetime value is normally 10 years. However, due to the improved waterproof property of the reinforced waterproof layer 4, the guaranteed lifetime value may be 20 years. it can.
This is because, as in the above-described conventional example, the surface layer is subject to deterioration due to sunlight, ultraviolet rays, rain, snow, etc., aging, and cracks due to long-term use. Then, rainwater enters the fine openings of the heat insulating foam layer from the cracks, and cracks and alterations occur due to freezing and the like, destroying the heat insulating foam layer, but these are prevented by the reinforcing waterproof layer 4 on the surface layer side. Is achieved by
The thickness of the reinforced waterproof layer 4 is preferably about 0.5 mm to 10 mm.
This is because at 0.5 mm or less, the reinforcing strength, waterproofness and heat insulation performance are insufficient.
On the other hand, when the thickness is 10 mm or more, the strength is sufficient, and the spraying construction time is increased, which impedes efficiency and increases the construction cost.
More desirably, the thickness is 1.0 mm to 5.0 mm.

Next, the surface of the reinforced waterproof layer 4 is one or a plurality of surface layers by any one of sunlight resistance such as ultraviolet light resistance, fire resistance, jumping fire resistance, heat insulation, etc., or a combination thereof. 5 is applied or sprayed.
The surface layer 5 has a spark performance that counteracts a spark such as sparks. Therefore, it is possible to provide a fireproof structure that prevents the occurrence of fire on the roof of the building in the Article 22 of the Building Standards Act.
Further, a material having sunlight resistance such as ultraviolet resistance is applied by painting or spraying.
Due to this effect, the reinforced waterproof layer 4 and the heat insulating foam layer 3 can prevent deterioration from ultraviolet rays and the like, and can exhibit a long-term alteration preventing effect.
Moreover, sunlight can be reflected by the thermal barrier paint and a heat insulation effect can be exhibited.
The surface layer 5 can be coated with a roller or a brush, or with an airless sprayer.

The thickness of the surface layer 5 is preferably about 20 microns minimum to 1.0 mm maximum.
This is because, when the thickness is 20 microns or less, the resistance to sunlight, such as ultraviolet rays, fire resistance, fire resistance, or heat insulation is insufficient.
On the other hand, when the thickness is 1.0 mm or more, cracks are generated due to thermal expansion of the reinforced waterproof layer 4 and the like, and the construction time becomes excessive and the construction cost increases.
More preferably, it is 20 microns to 60 microns.
The construction method of the present invention, the heat-insulating foam layer 3, the reinforced waterproof layer 4 and the surface layer 5 of the construction structure have extremely high weather resistance due to the construction thereof, and without losing elasticity even at a low temperature of -50 ° C. Elasticity can be maintained even at high temperatures of ℃.

FIG. 4 and FIG. 5 are cross-sectional views showing that it is possible to seamlessly carry out the installation of the fixture 7 such as a bolt for attaching the substrate as described above. FIG. 5 shows a repaired state when the bolt protection cap 8 is provided.
FIG. 6 shows a repair method when there is a discontinuous portion such as the opening 1a damaged by the slate which is the substrate 1. It is possible to cover the opening 1a seamlessly by covering the opening 1a with a repair material 9 such as a cloth or a synthetic resin sheet and spraying the heat insulating foam layer 3 thereon. In addition to this, the discontinuous portion is the same for the connecting portion of the substrate 1, the corner processing portion, and the like.

Next, as shown in FIGS. 7 and 10, the end side surface 1 b of the substrate 1 is waterproofed with the heat insulating foam layer 3 and the reinforcing waterproof layer 4, or the end side surface 3 b of the heat insulating foam layer 3 is covered. Further, waterproofing can be performed with the reinforced waterproofing layer 4. Although these are local examples, the other discontinuous portions that normally cause water leakage can be protected seamlessly.
4 and FIG. 5, the rust is generated due to long-term corrosion. By the method of the present invention, oxygen is blocked to cover the rust and corrosion. Can be prevented.

Hereinafter, the second embodiment of the present invention is applied to a non-metallic material such as a slate, concrete, a waterproof sheet, a wooden material, or a base material of a roof or wall of a metal building.
The primer layer 6 is formed on the surface by painting or spraying, and the heat-insulating foam layer is sprayed on the surface of the primer layer 6 by spraying a quick-drying heat-insulating foam layer 3 made of a resin foam material such as polyurethane. The degree of adhesion to the substrate 1 of 3 is improved.
FIG. 8 is a perspective view showing the structure after construction in the construction process order, and FIG. 9 is a cross-sectional view perpendicular to the corrugation of the substrate. FIG. 10 shows a repair structure in which the end side surface 1b of the substrate 1 in Example 2 is waterproofed with the heat insulating foam layer 3 and the reinforcing waterproof layer 4, or the end side surface 3b of the heat insulating foam layer 3 is covered. It is sectional drawing.

  The primer layer 6 is not essential, but usually, the surface of the roof substrate 1 is often attached with algae, mold, dust, latency and the like. Although it may be omitted, overall, the adhesion of the heat insulating foam layer 3 can be improved by providing the primer layer 6. As the material, an aqueous or oily primer or the like or a mixture thereof is selected. The primer layer 6 can further enhance the aforementioned asbestos sealing effect.

Example 3 of the present invention eliminates the heat-insulating foam layer 3, forms the primer layer 6 on the surface of the substrate 1 by painting or spraying, and directly applies the reinforcing waterproof layer 4 to the surface by spraying. The surface layer 5 is constructed on the surface.
FIG. 11 is a perspective view showing the structure after construction in the construction process order, and FIG. 12 is a cross-sectional view perpendicular to the corrugation of the substrate.
If comprised in this way, since there is no heat insulation foaming layer 3, construction thickness can be reduced significantly and drastic cost reduction can be aimed at by the reduction of a weight and the great shortening of construction time.

In this embodiment, as shown in the enlarged schematic diagram of the structure in FIG. 13, the material of the heat insulating foam layer 3 and / or the reinforcing waterproof layer 4 is made of a short glass fiber, a short carbon fiber, or a short dimension. The reinforcing fiber 10 such as stainless steel or metal fiber such as titanium is mixed. For the wire diameter, length, and the like of the reinforcing fiber 10, the optimal effect can be selected and used according to the material, and the reinforcing effect can be adjusted. For example, in the case of glass fiber or carbon fiber, the wire diameter of the strand is 3 to 20 microns (μm), and it is mixed alone or twisted to 0.5 to 2.0 mm ( mm) fiber bundle. By making the length of the strands or fiber bundles 1 to 30 mm (mm), it is easy to be mixed into the material of the heat insulating foam layer 3 and / or the reinforced waterproof layer 4, and a great reinforcement It can give an effect.
Due to the reinforcing effect of these reinforcing fibers 10, the heat insulating foam layer 3 and / or the reinforced waterproof layer 4 can exhibit higher strength, the construction thickness can be reduced, the weight can be reduced, and the construction time can be greatly shortened. The cost reduction effect which reduces the fee for using the resin material can be obtained.

In the present embodiment, the surface of the reinforced waterproof layer 4 is mixed with the surface layer 5 of a material having solar resistance such as ultraviolet rays and / or a material having fire resistance and flying resistance. The layer 5 is omitted, and the surface-reinforced waterproof layer 11 is the top surface.
For example, the resistance to sunlight such as ultraviolet rays can be enhanced by mixing an acrylic or two-component polyurethane resin or the like. As an example of the material of the surface reinforcing waterproof layer 11, for example, a material mixed with a product name “Saraseine T” (registered trademark) manufactured by Asahi Glass Polyurethane Building Materials Co., Ltd. (registered trademark) is used.
In addition, the fire resistance and jump fire resistance of the surface-reinforced waterproof layer 11 is imparted by mixing silica sand having a particle diameter of 0.2 to 0.3 mm (mm) φ, usually called No. 7 silica sand. I can do it.
Then, the surface layer 5 can be omitted due to these durability performances, and the direct surface reinforcing waterproof layer 11 can be made the uppermost surface.
In this embodiment, since the process and material of the surface layer 5 can be reduced, there is an effect of cost reduction by reducing the usage amount of the resin material of the surface layer 5 and efficiency by significantly shortening the construction time.

  As described above, as described above, by providing a repair structure having an extremely large number of features for the roof or wall of a building, as described above, a new technology can be obtained by reducing costs and shortening construction time. Along with contributing to the revitalization of the industry due to increased demand, it also demonstrates the effects of industrial accidents, asbestos environmental problems, energy-saving measures to prevent global warming, and the resolution of current problems.

(registered trademark) is used.
In addition, the fire resistance and jump fire resistance of the surface-reinforced waterproof layer 11 is imparted by mixing silica sand having a particle diameter of 0.2 to 0.3 mm (mm) φ, usually called No. 7 silica sand. I can do it.
The surface layer 5 can be omitted and the surface reinforcing waterproof layer 11 can be directly used as the uppermost surface due to these durability performances.
In this embodiment, since the process and material of the surface layer 5 can be reduced, there is an effect of cost reduction by reducing the usage amount of the resin material of the surface layer 5 and efficiency by significantly shortening the construction time.
