Description

[Detailed description of the invention] TECHNICAL FIELD This invention relates to architectural structures.

Specifically, the present invention relates to a lightweight building structure that can be used as both a roof structure and a wall structure of a building.

The aim is to provide an extremely useful building structure that is lightweight, earthquake resistant, fire resistant, thermally insulating and soundproof.

Traditionally, it has been thought that it is preferable to use building materials with a large self-weight for earthquake-resistant building structures, but subsequent research has shown that as buildings become taller, lightweight building materials actually have better earthquake resistance. As a result, it has been newly introduced into the earthquake resistance law of the Construction Law.

However, conventional construction material needles do not have this kind of lightness,
For example, roofing materials include Japanese tile finish, Color Best board finish, single finish, metal plate tile bar finish, and slate finish, but these are unsuitable for the times, and do not have good soundproofing properties and are resistant to rain. It has many drawbacks, such as the sound echoing inside the room, the cracks caused by the steps, being weak against shock, not safe against strong winds, and poor durability, with surface makeup fading and deterioration such as efflorescence after 1 to 8 years. It was something.

On the other hand, conventional wall structures include earthen walls, concrete walls, mortar walls, etc., but all of them have a large weight and crack due to automobile vibrations, earthquake vibrations, strong wind vibrations, ground subsidence, etc. within 1 to 2 years after new construction. This makes it easy to have areas where the spear shin has come off or where the mortar has come off. In other words, if a large amount of cement is used, it will be strong, but shrinkage cracks will occur and mortar cracks will form within a year when it dries, and because it has a large self-weight, it will be weak against earthquakes and vibrations. Also, the quality may vary depending on the brand, and the slump W10 (vertical plane) condition may deteriorate depending on the ratio of water and cement.
There are major defects in the building structure due to the wall surface.

With the above points in mind, the present inventor has conducted extensive research in order to obtain a lightweight architectural structure suitable for the new earthquake resistance method, which has excellent heat insulation properties, does not deform due to pressurized heating, and has excellent fire resistance and sound insulation properties. As a result of repeated efforts, the present invention was achieved.

That is, a board selected from plywood, board, slate, etc. is bonded to both sides of a synthetic resin foam board via an adhesive layer, and a polyurethane coating layer is provided on the surface of both boards, and the outer surface is Urethane caulking is applied to this and the four end faces of the plate, and the surface of the synthetic rubber sheet is coated with KFi.
A sandwich that can be harvested on roofs and walls, characterized in that a polyurethane resin is applied and a sprayed finish layer is applied to the surface, and a sprayed finish layer is also applied to the inner surface of the polyurethane coating layer. This led to the invention of a type of lightweight architectural structure.

The present invention will be explained with reference to the drawings.

The first section is l'i! of the basic structure of the structure of the present invention. It is a sectional view of a perspective view showing an example.

As shown in this figure, the present invention has a synthetic resin foam board (1) in the center, and a board (3) ri) is bonded to both sides of the board via an adhesive layer (2) (S'). The surface of the plate (3) (a) on both sides is covered with a polyurethane coating layer (

6] is applied to prevent water from entering from this end face.

Further, a polyurethane resin (7) is applied to the surface of the synthetic rubber sheet (5), and a finishing layer (8) is provided on the surface by spraying.

On the other hand, spraying is also applied to the inside surface of the polyurethane coating layer (j), that is, the surface C that will be the indoor side during construction (inner surface side).
i>.

The structure of the present invention has a sandwich type structure as described above, and this structure #i can be used both as a roof structure and as a wall structure.

The synthetic resin foam board (1) in the structure of the present invention is preferably a synthetic resin foam commercially available under trademarks such as "Styrofoam" and "Kanelite Foam".
The thickness is preferably about #'i5 to 50111.

In addition, as the plate (3) (3) in the present invention, plywood such as plywood, panel board, slate board, board board, etc. are mentioned, and plywood board, panel board, etc.' are preferable for roof structures, and slate board , board is preferred for wall construction. However, it is not limited to these, and both sides of the sandwich do not need to be made of the same material (3) (a), but may be of the same or different materials. be.

In addition, the thickness of this plate (3) (,?) is 5~801E
ml is preferred.

As the adhesive layer (2) (<d) for bonding the plate (3) (,?) to both sides of the synthetic resin foam board (1), an epoxy adhesive gives excellent results.

The polyurethane coating layer (4) (1) provided on the surface of the plate (3) (J) may be a prototype polyurethane resin layer and may be uniformly coated with a roller or the like.

Furthermore, the synthetic rubber sheet (5) attached to the outer surface is
If it has a thickness of 0.5 to 5 m and is attached with a neoprene adhesive, it will be good.

In order to provide waterproofness to the joint part of the synthetic rubber sheet (5) and the four end faces of the synthetic resin foam board (1) and the board (3) (i), 1. The urethane caulking (6) to be applied may be a corrugated urethane caulking material. - Then apply urethane caulk to the joint part of the synthetic rubber sheet (5) and then apply polyurethane resin (

Furthermore, the finishing layer (8) (FO
Preferred methods include spraying using epoxy or acrylic resin lysine as the main material, or spraying using a polyurethane foam patch injection method.

In order to make the present invention more specific, examples will be explained in accordance with the steps of template structure construction and wall surface structure construction.

(1) Roof Structure Construction Procedure Example ゛゛ First Step Board (3) Two panel boards are used as the boards (3) ta), a primer is applied to the back side of the panels, and the primer is completely dried. Next, as an adhesive for the adhesive layers (2) and (4), the same as Nisudine Graft Taki 22A manufactured by Tansui Kagaku ■ (Na
A 2 to 1 mixture of 22B is applied over the dried primer. On the other hand, synthetic resin foam board (1)
For this, use a styro-ohm, apply the same adhesive as above to the back side of the styro-ohm, attach it to the adhesive side of one of the control panel boards, and then apply the same adhesive to the front side of the styro-ohm. Then attach another panel board in the same way.

In this way, a sandwich-like plate is obtained, which is then pressed under pressure to completely adhere to it. Afterwards, let it air naturally for one day to ensure complete adhesion. FIG. 2 is a cross-sectional view of the product thus obtained.

2nd step Apply urethane caulking (6-inch urethane sealant "Dick Seal" 1000, made by Dainippon Ink Co., Ltd.) to the four end faces of the above sandwich-like plate, and apply the styroam and spring. Adds waterproofness to the edge of the board.

This is because water can enter through even the smallest gaps and cause leaks.

It takes about 18 hours to completely dry this urethane caulking (6) by natural drying.

8th step As the polyurethane coating layer (4) (4'),
Using Soflan R (-corrugated urethane resin) from Lan Kako C Co., Ltd., dilute the stock solution with twice the amount of Dorol, apply this solution to the rollers to uniformly spread it on one side at a time. Apply to.

In other words, wait until one side is dry before applying it to the other side. One side requires about 2 days of natural drying to completely dry.

A cross-sectional view of FIG. 8 shows what the second and eighth steps have been completed.

Fourth step: Apply epoxy or acrylic as a material for the bamboo spray finishing layer (s) to the inner surface (the indoor side) of the sandwich-like board on which the polyurethane coating layer (4) (4') has been applied. For spraying, adjust the viscosity of the above-mentioned Soflan R and Doruol to the resin ricin so that it has a viscosity suitable for spraying, mix it from raw, adjust the coating liquid, and spray it with a spray gun to a thickness of about 0.5mm. Spray paint on 5 to 10 ff. This ricin spray may be applied in various patterns.

The finishing layer sprayed with ricin exhibits almost non-combustible properties in the event of a fire, resulting in good fire prevention results.

It takes several days.

FIG. 4 is a cross-sectional view of the finished product after completing the fourth process.

Fifth step: Apply the sandwich-like plates obtained in the above manner to the field corner of the roof.
9). In this case, the above-mentioned glue spraying is set with the side facing down and the Soflan R coating layer facing up, and then stopped with the nail a1. Nail αO
The length of the barberry aO is 5 to 101, and using a wooden drill, drill a nail Q from the top of the Soflan R coating layer so that the head of this barberry aO does not protrude.
Drill a hole approximately 8 ff deep at the location where 1) is to be punched. After this set is completed, the eaves drain plate αp is nailed to the lowermost end surface (the length of the nail is 8 to 15111 cm) (see Fig. 5).

The second eave drain plate αυ is a metal plate with a U-shaped cross section, for example, and its width, thickness, and shape vary depending on the place of use, and another eave drain plate is attached to the corner portion.

In the sixth step, approximately 1 cW of the tip of the eaves drain plate αυ is left and the synthetic rubber sheets (5) are successively pasted from the bottom.

This synthetic rubber sheet (5) is commercially available from, for example, Toyo Rubber Co., Ltd., and is available in lengths of 10 m and 20 m, and its width is 120 cm. Depending on the design, a long synthetic rubber sheet may be attached as is, or it may be cut and attached as appropriate.

This pasting method involves first applying a synthetic rubber adhesive onto the Soflan R coating layer, and then applying the same adhesive to the synthetic rubber sheet (
5) Also apply to the back side. When both are dry, paste them together and apply synthetic rubber seams.) (The joint part of 53 comrades is overlapped with about 103 to completely prevent rainwater from entering. In addition, leave about 1 clI of the eaves drainage board αυ. This is to prevent the synthetic rubber sheet (5) from peeling off in the event of a disaster such as a typhoon.

Next, the remaining 1 cIl of this eaves drainage board, the joint between this part and the synthetic rubber sheet (5), and the joint between the synthetic rubber sheet (5) were coated with the end face of the sandwich-like board. The same urethane caulking is applied.

Step 7: Apply polyurethane resin (
7), using the same Soflan R as in the polyurethane coating layer (4) (4'l), mix this Soflan R stock solution with 8 times the amount of Dorol and apply it with a roller. Apply it evenly with a swipe.

This application creates a urethane film, and the top layer is sprayed as a finishing layer (
This is to strengthen the adhesion with the synthetic rubber sheet (6), and must be done after the synthetic rubber sheet (6) is completely dry. ,
Further, preferable results can be obtained one day after mixing Soflan R stock solution and Doluol in a ratio of 1:8.

8th step After the above Soflan R film has completely dried, the finishing layer (
8) As an aside, epoxy or acrylic glue is used for painting.

First, a mixture of the above-mentioned Soflan R stock solution and Drol in a ratio of 1:3 is mixed with ricin paint while adjusting the viscosity appropriately to obtain a viscosity suitable for spraying.

Then, the paint is sprayed to a thickness of 0.5 to 111W using a spray gun and allowed to dry completely.

Of course, this spraying may be performed to finish in various patterns.

Further, the reason why urethane resin is mixed with the ricin paint is to obtain adhesion to the synthetic rubber sheet (5) and to create a structure that is resistant to discoloration, weathering, and other peeling.

``This spraying is not limited to this epoxy-based or acrylic-based lysine for the finishing layer (8), and the foaming batch injection method may be used for urethane-based spraying, which is suitable for small-scale construction. The spraying in the fourth step and the spraying in the eighth step do not necessarily need to use the same resin spear, and the spraying of different materials may be used as a finishing layer.

FIG. 5 is a partially cutaway view of the roof structure after the eighth step (the urethane caulking part is omitted). However, (A) in FIG. 5 shows the entire structure shown in FIG. 4 after the fourth step of Fi has been completed.

(11) Example of a wall structure construction procedure The procedure for constructing a wall structure in the present invention is almost the same as the roof structure construction procedure example described above, except for the plate (3).
As for (3), it is preferable to use a slate board for the outside surface and a boat board for the inside surface, rather than plywood.

This slate board includes plywood slate, cement slate,
There are asbestos slates, etc. Boat boards include gypsum board, Glaster gypsum board, asbestos gypsum board, wood wool cement board, wood chip cement board, etc.

First step: Primer is applied to the back side of the slate board as the board (3), and after drying, an epoxy adhesive is applied as the adhesive layer (2) using a roller. Similarly, mK Glimmer is applied to the back of the gypsum board as the board (3), and after drying, the same adhesive is applied to the roller using a screwdriver.

Also, a styro-ohm is used as the synthetic resin foam board (1), and its outer surface g! Apply the same adhesive to the ll (outdoor side surface) using a roller and attach it to the adhesive-coated surface of the slate board. Next, the same adhesive is applied to the inner surface 1111 (m, which is the indoor side) of the styro-ohm, and it is bonded to the adhesive-coated surface of the above-mentioned gypsum board.

The sandwich-like plates thus obtained were pressed together to make them stick together and left for one day.

Nao, what is the shape of the styro-ohm? 'a, for example, thickness 5~5Qsw, width u 45~200ts, length Fi
Examples include those with a length of 60 to 800 cm.

Second step: The four end faces of the above-mentioned sand plate are treated with furetane caulking (6) in the same manner as in the case of the roof structure.

Eighth Step: Apply a polyurethane coating layer (4) (4'') on the outer slate board surface and the inner gypsum board surface of the sandwich board in the same manner as in the roof structure described above and dry completely.

Note that FIGS. 2 and 3 shown in the roof structure described above are also shown in the same drawings in this wall structure. In other words, FIG. 2 is a sectional view when the first step is completed, and FIG. 3 is a sectional view when the eighth step is completed.

After completing the fourth and eighth steps, the sandwich-like plate is set on the wall.

Figures 6 to 9 show this situation, and Figures 6 and 7 show the case where it is installed on a steel structure, and Figure 6 II'iR.
When installed by tightening bolts with an L-shaped plate (toward) on steel,
Figure 7 shows how it is attached directly to the H steel (2) with bolts α◆.

In addition, Figures 8 and 9 show how it is attached to a wooden pillar (top) erected on a foundation (top) with nails αη, and in Figure 8, the upper and lower beams are installed so that the , Fig. 9 shows the upper and lower beams (to) being installed so as to cover them as well.

Note that in FIGS. 6 to 9, (l indicates a semi-finished product of the structure of the present invention that has been completed up to the eighth step.

5th step Spray the Soflan R membrane surface of the plasterboard board, which is the inner side of the sandwich board set on the wall surface as described above, which is the indoor side, as a finishing layer (d). Spray the resin lysine as a finishing layer or polyurethane foam patch. Spraying by injection method applies a finishing layer.

Step 6: On the other hand, the outer surface of the slate board, R1l.
The same adhesive for the #i roof structure is applied to the 11th side and dried, the same adhesive is applied to the back side of the synthetic rubber sheet (5) and dried, and the two are bonded together.

(5) (7) The overlap of the joint part is 5
~10 cM width is preferred. Further, the synthetic rubber sheet (5) may be applied either vertically or horizontally.

Seventh step: Mutual joints 1 of the synthetic rubber sheets (5); the same urethane caulking as used for the roof structure is applied to provide waterproofness and prevent water from entering.

8th step Polyurethane resin (
As 7), apply Soflan R as above. This is a process in which the next step of spraying with the resin lysine is to perfect the adhesion with the finishing layer (8).

9th Step Wait until the polyurethane resin coating on the top surface of the synthetic rubber sheet (5) is completely dry, then spray epoxy or acrylic resin lysine as the finishing layer (8) in the same way as for the roof structure. is processed. This spraying is the finishing layer (8)
Once it dries, the wall structure of the present invention is completed.

Part (C) in Figures 6 and 7 shows the urethane caulking part that was waterproofed after construction.

As mentioned above, the construction procedure for both roof structures and wall structures is to set the semi-finished structure of the present invention structure on the roof or wall surface, and then perform further processing to complete the structure of the present invention. Although an example has been shown, the procedure is not limited to such a procedure. It is also possible to set the sheets one by one.

Furthermore, the wall structure of the above embodiment may be used as a roof structure, and the roof structure may be used as a wall structure.
The design and construction should be done appropriately depending on the four seasons in Japan and the construction area.

Honshizukumei is lightweight because its main material is a lightweight synthetic resin foam board, and the plates attached to both sides in a sandwich-like manner are rigid, strong, and resistant to heat and pressure. It is completely waterproof because it is coated with a synthetic rubber sheet, and the finishing layer is made of resin such as lysine, making it fireproof and almost non-flammable. It is extremely effective, as it can almost completely prevent fires caused by flying sparks.

In addition, the structure of the present invention is notable for its light weight, so it exhibits a high degree of earthquake resistance, and the synthetic resin foam board has excellent heat insulation properties, so it has a large energy-saving effect and is effective in preventing snow accumulation in winter, and is also soundproof. It is highly flexible and prevents noise pollution and noise, making it possible to live comfortably.

Furthermore, since most of the interlayer parts of the structure of the present invention have a polyurethane coating layer with excellent anti-scratch properties, the interlayer parts have excellent durability and maintain reliable quality for a long period of time. .
