Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an integral structure of a roof and a roof base, and an external insulation and waterproof construction method by integrating the roof and the roof base, and more particularly, to a roof and its roof base. The present invention relates to a structure that integrates a roof base provided at the lower part of a roof, and an external insulation and waterproof construction method for constructing the roof and roof base to externally insulate and waterproof a structure such as a house.

(Prior Art) In general, methods for insulating structures such as houses include methods for insulating the inner walls of the structure and methods for insulating the outer walls, more specifically, the outside of the outer walls. In the past, the former method was generally adopted because it was difficult to install it on the exterior wall side due to the flexibility of the insulation material, but in recent years it has been noted that there is a significant difference in insulation effectiveness. is,
Rather, the latter method is increasingly being adopted.

By the latter construction method, as a structure constituting the roof and the roof base below it, conventionally, as shown in FIG. A heat insulating material 11 is installed between the body 10 and 10, and a concrete panel 12 is installed on the outside thereof.
There is a structure that includes a structure.

(Problems to be Solved by the Invention) However, such a structure has the following problems.

(B) That is, the columnar bodies 1o are provided outside the foundation 1b, and the heat insulating material 1 is pre-formed between the columnar bodies 10 and 10.
1 is incorporated, and a pre-formed concrete panel 12 is provided on the outside.
o. The insulation material 11, the concrete panel 12, and the roofing material 8b are not integrated, and gaps are created between these components. As a result, moisture permeates and condensation occurs in the gaps due to moisture, etc., resulting in waterproofing. Her sexuality was severely impaired.

(b) Particularly in the structure described above, the roofing material 8b itself is composed of an aggregate of single roof finishing materials such as so-called shingle materials that are separate from the roof foundation, so that the roof material 8b itself is made up of a single roof finishing material such as a so-called shingle material that is separate from the roof foundation. Water penetration was also significant, and from this point of view, the lack of waterproofness had become a serious problem that could not be ignored.

(c) Furthermore, since the roofing material is composed of an aggregate of a single roof finishing material, the construction of the roofing material itself is extremely complicated.

(d) Furthermore, as a result of the above-mentioned gaps being created between each component, the gaps become air retention layers and radiant heat is stored, and as a result, this air layer becomes abnormally high temperature. Despite this, there was a problem in that the insulation effect was impaired.

Of the above two construction methods, the present invention is an external insulation construction method that insulates the outer wall, particularly an external insulation waterproofing construction method that is constructed by integrating the roof and the roof base while taking waterproofing aspects into consideration, and It is made as an integral structure, and the entire roof and roof base form an integral heat-insulating and waterproof layer with no gaps, thereby providing insulation based on the generation of condensation and heat retention. The purpose is to significantly improve waterproofing, especially the waterproofing effect.

(Means for Solving the Problems) The present invention was made to solve the above problems in order to achieve the above object, and the means for solving the problems are to insulate the upper surface of the foundation. The roof is coated with urethane as a material, and the coated upper surface is coated with mortar as a base material made of black magnetic pearlite mixed with chips and fiber materials to form an integral roof base, and the roof is placed on the top surface of the roof base. By integrally providing a waterproof layer as a material and integrating the roof material and the roof base, external insulation and waterproofing can be achieved.

(Function) In other words, since the roofing material, base material, heat insulating material, etc. are integrally constructed and formed as a single heat-insulating and waterproof layer, there is naturally a gap between each component that makes up the roof material and the roof base. There are no gaps, so there is no condensation or heat storage like in the past, and the waterproofing and heat insulation properties are improved, and the roofing material itself is composed of a waterproof layer that is integrated into the roof base. This prevents moisture from penetrating into the roof base, and since the urethane that makes up the insulation material has waterproof properties, even if moisture penetrates into the roof base, the roof base will not absorb moisture. It will not be affected by moisture,
Therefore, efforts have been made to particularly improve waterproofness.

Furthermore, since the black foundation stone pearlite contained in the mortar itself is composed of closed cells, there is no internal water absorption and the water absorption power is small, and the chips and fiber materials mixed in the mortar have excellent water absorption power. , which further contributes to improving waterproofness.

(Example) Regarding embodiments of the present invention, first, an example of an external insulation and waterproof construction method by integrating a roof and a roof base will be described.

First, as shown in Figure 1, a concrete foundation 1
Anchor bolts 2 are driven into the foundation 1, and then urethane foam is sprayed onto the foundation 1 as a heat insulating material, thereby painting the foundation 1 integrally with urethane. As a result, as shown in FIG. 2, urethane is integrally constructed as a heat insulating material 3 on the foundation 1.

Next, as shown in Fig. 3, a wire mesh 4 is arranged on the top of the urethane 3, and then, as shown in Fig. 4, a plurality of joint bars 5 are arranged at equal intervals across the width of the roof. Set up

Next, aggregate for mortar is prepared by mixing a polyamide-based fiber material 13 with rubber attached to the surface as shown in Figure 6 (b) in Kuronseki pearlite, which is composed of closed cells and has a low water-absorbing power and has water-absorbing power only on the surface. mixed with river sand, cement, and water,
The mortar obtained by stirring is applied to the upper surface of the heat insulating material 3 with a trowel to integrally apply the coating. At this time, the wire mesh 4 and the joint rods 5 are buried in the mortar, and the mortar allows the base material 6 to be integrally applied to the upper surface of the heat insulating material 3, as shown in FIG. .

An example of the composition of the arsenite pearlite contained in the mortar is as follows.

Silicon dioxide 75.41% Aluminum oxide 12.85% Diiron trioxide 0.64% Magnesium oxide 0.36% Sodium oxide 3.7
0% Potassium oxide 4.55% Calcium oxide 0.82% Then, by painting the base material 6, the integrated construction of the roof base 7 is completed, and then a long piece of synthetic rubber is wrapped separately into a roll. Figure 6 shows waterproof N8 as a roof material made of a waterproof sheet of
By integrally adhering it to the upper surface of the roof base 7, that is, the upper surface of the base material 6, as in (a), the integral construction of the roof base and the roof is completed.

The integral structure of the roof and roof base formed by the above-mentioned construction method, that is, the external insulation and waterproofing construction method by integrating the roof and the roof base, is as described above.
A concrete foundation 1, a heat insulating material 3 made of urethane coated on the foundation 1, and a base material made by mixing river sand, cement, and water with mortar aggregate made of IT stone perlite mixed with fiber material. A roof base 7 is integrally formed with the roof base 6, and a waterproof layer 8 as a roofing material made of a waterproof sheet is integrally provided on the upper surface of this roof base.

That is, the roof base can be integrally constructed by spraying or painting the heat insulating material 3 on the foundation 1 and painting the base material 6, and the waterproof layer 8 made of a waterproof sheet can be integrally attached to the roof base. As a result, there are no gaps between the foundation 1, heat insulating material 3, base material 6, and waterproof layer 8, which are the constituent members.This prevents internal condensation from forming in the gaps, and prevents the roofing material itself from forming. Since it is made of a waterproof sheet, it also prevents moisture from penetrating into the roof base, which significantly improves the overall waterproofing effect.

In particular, the black four stone pearlite contained in the mortar of the base material 6 has closed cells and has low water absorption power, and the urethane as the insulation material 3 has waterproof properties, so it also has secondary properties on the roof base material 7 side. This results in a waterproof effect.

In the above embodiment, the waterproof layer 8 is formed of a synthetic rubber waterproof sheet, but the material of the waterproof sheet may be other than synthetic rubber, such as vinyl chloride resin. The waterproof layer 8 does not necessarily need to be formed using a waterproof sheet; for example, a waterproof layer made of asphalt or resin may be formed as a roofing material by coating asphalt or waterproof resin on the base material 6. . In short, it is sufficient that the waterproof layer 8 as a roofing material is provided integrally with the roof base 7.

In the above embodiment, the foundation 1 is made of concrete, but the material of the foundation 1 is not limited to this, and may be made of iron plate, for example.

Further, in this embodiment, the anchor bolt 2 is driven before the urethane coating, but the step of driving the anchor bolt 2 is by no means an essential step.

Moreover, the process of arranging the wire mesh 4 and the joint bars 5 is by no means an essential configuration.

Further, in this embodiment, the urethane is applied onto the base 1 by spraying, but the means for applying the urethane is not limited to spraying, and may be applied, for example, by coating. In short, it is sufficient that urethane is provided as the heat insulating material 3 on the upper surface of the foundation 1 by painting.

Furthermore, in this embodiment, the base material 6 is composed of a special mortar aggregate as described above mixed with cement, river sand, and water, but it is never necessary to mix cement, river sand, and water at the same time. Instead, it is sufficient that the base material 6 is made of mortar aggregate made of Kuromeite pearlite mixed with chips, fibers, etc. Note that the means for applying the base material 6 is not limited to the application using a trowel as in the embodiment.

In addition, in the above embodiment, the polyamide fiber material is mixed with the heloitic pearlite, but the type of fiber material is not necessarily a problem, and it is not limited to fiber materials, and even chips that are cut pieces of rubber can be used. Well, it is by no means limited to fibrous materials, and the material is never in question.

Furthermore, the composition of the Noborite pearlite contained in the mortar is not limited to the examples.

(Effects of the Invention) (A) As in the case of ridges, the present invention is capable of integrally constructing a roof base by coating the foundation with urethane as a heat insulating material and mortar as a base material. In addition, a waterproof layer as a roofing material is integrally provided, and the roofing material and roofing material are integrated to perform external insulation and waterproofing, so each component of the roofing material and roofing material is a single piece of insulation. It forms a waterproof layer, which prevents the formation of gaps between each component as in the past, thereby preventing the occurrence of condensation, and the roofing material itself is a waterproof layer integrated into the roof base. This prevents moisture such as rainwater from penetrating into the roof base, and even if it does, the urethane that makes up the heat insulating material is waterproof, and the urethane contained in the mortar of the base material is Because stone perlite has water resistance and fiber materials have water-retaining capacity, a secondary waterproofing effect occurs even in the roof base, which is an exceptional product that significantly improves the waterproofing effect of the entire roof and roof base compared to conventional methods. It has come to have a remarkable effect.

(b) Also, as mentioned above, since there are no gaps between each component, heat is not stored in the gaps as in the past,
Moreover, since the black perlite contained in the base material itself has heat insulating properties, the overall heat insulating effect is significantly improved compared to the conventional method.

(C) Furthermore, since the roofing material is not composed of a single aggregate of roof finishing materials as in the past, but is composed of a waterproof layer consisting of a single layer, the construction of the roofing material itself is also conventional. It has the advantage of being much easier than

(d) Furthermore, since it is an integrated construction method in which urethane is used as a heat insulating material and mortar is used as a base material, and a waterproof sheet or painted roofing material is integrally installed on the roof base, for example, curved shapes, etc. Even if there is a change in the slope of the roof, the construction can be carried out flexibly in accordance with the change, and the construction work is simple and quick, so it has the great practical benefit of being suitable for new construction and renovation work.

(e) In any case, the present invention provides an unprecedented integrated structure in which the roof and the roof base are integrated as one structure, and by such integration, not only external insulation but also
We have now been able to provide an innovative construction method that can waterproof the entire roof and roof base.
