Abstract

PROBLEM TO BE SOLVED: To make a wall firm and dense, by forming a space with double structural plates and charging and foaming a resin in the space. SOLUTION: A sheet of structural plywood 1 constituting the center of a wall is held by outside studs 2-1 and inside studs 2-2 to integrally form a double- wall. In this time, holes 8 for injection of urethane and for spouting excessive urethane are made on the plywood 1. Sills are arranged prior to the erection of the wall and fixed by bolts, nuts, and metal blocks. Then, the column 4 is connected to the double-wall to erect it and bracings are fitted to the sills to temporarily fix them. Subsequently adjacent walls are erected in turn. Finally, the horizontality and verticality are confirmed and the adjacent parallel walls are fixed to the sills. After completion of the works, the external structural plywoods 3 are nailed at the whole face. A resin agent is injected in the space between the plywoods 1, 3. The resin is injected at first into the lowermost hole 8 to spout the foamed resin from the second hole. After visual confirmation thereof, the resin is injected in the next hole 8 and the procedure is reteated. In this way, the heat-insulation work is rapidly and easily executed and a high quality wall can be obtained.

2. Description of the Related Art 2 inches x 6 which is said to be strong against conventional earthquakes
Inch two-by-six and conventional construction methods are also supported by thickening the pillars. This is heavy, and the labor of the work is a burden on the Japanese people, and the room has been made smaller due to the larger cross section. The heat insulation is mainly made of fiber such as glass wool, which is weak against dew condensation and diverges slowly after containing water, causing internal dew condensation water to damage the body. A hard urethane foam resin plate with good performance created a gap during the construction of the on-site cutting, which made it impossible to achieve high confidentiality. The method of scraping each individual material has not been developed to make it earthquake-resistant and at the same time sensitive and economical at a popular mass price.

[0003]

[Problems to be Solved by the Invention]

I. Increasing the cross-sectional area by making the pillars thicker makes the room narrower and imposes a labor burden. B. The popularity of two-by-four is rising, but there are too many legal restrictions. C. Even though there are many types of building materials in the city, they are suffering from the problem of condensation. D. In order to improve the high confidentiality, both industrial products and on-site construction depend on the skill of the worker, and there are many worries about site management. E. As a result of extreme price competition, there is too much emphasis on sham makeup and there is a lack of emphasis on the structural body. C. It is impossible or inconvenient to connect the top, bottom, left and right with the industrial drum drum flash panel method, and I am worried about how to build it by destroying a part. D. The one-sided plywood covering manufactured by the factory is heavy and requires heavy equipment for handling. When the structure body is emphasized, the secrecy becomes late, and if it is brilliant, the body becomes late, and if the secrecy is mainly concerned, the workability of the body is deteriorated, and so on. The present invention has been made to solve these disadvantages.

[0004]

[Means for Solving the Problems] It has been confirmed by two-by-four, etc. that the single structural plywood as a building material has good seismic performance. It features an integrated structure to obtain compressive strength and heat insulation performance. FIG. 1 is a plan view of the structure, FIG. 2 is a perspective view, FIG. 3 is a front view, and FIG. 4 is an exploded view of the front view. The partial outline of the wood axis of the wall shows the relationship between the pillar (4), the stud vertical cross bar, the base (6) and the beam (7) in the front view of FIG. An outer stud (2-a) and an inner stud (2-b) are sandwiched and integrated with a structural plywood (1) that forms the center of the wall. The name of this shape is double wall. The connection may be nails, wood screws, adhesives alone or in combination. Make the required number in advance before building. The purpose of the double wall sandwiching the true structural plywood is that it can be easily fixed with nails or the like from the direction of the arrow as can be confirmed by disassembling the plan view of FIG. 1 and the front view of FIG. Prior to building, the pillar (4) and the double wall are connected with nails or the like. Or, after the pillars are built in a predetermined position, a double wall is attached later to build a skeleton, and the standing method is sequentially advanced. The outer plate (3) is attached as shown by the dotted arrow in FIG. 4 after the double wall connection. After completing the building, install the openings such as windows. The space of the outer plate (3) and the true plate (1) is a foam layer (9). Prior to filling the foaming agent, a predetermined number of injection holes are formed in the true plate (1). The holes are an injection hole and an extra spout hole, and a drill hole may be previously provided at the time of manufacturing the double wall. Inspect the entire wall and make sure there are no defects. The foaming machine is loaded on site and the nozzle of the machine tool is used to inject the hole (8) resin.
The resin causes a chemical reaction in the foam layer (8) and spouts from other holes. Visually check the filling in the spouted state. The structure of the double wall is the same, but the order of how to build and how to build the outer plate may be set as follows. Since the division method is excellent in speeding up, it becomes impossible to visually confirm the space portion (9) between the outer plate (3) and the true plate (1). The outer studs (2 to a) and the outer structural plywood (3) are fitted in advance. Also, the inner studs (2 to b) and the true structural plywood (1) are combined to make two halves. This is called a single wall,
The outside of the single wall and the inside of the single wall. As for the way of building, the pillar (4) and the outer portion of the single wall (2 to a and 3) are joined to build a skeleton, and the standing is proceeded. Then, the inner portions (2-B) of the single wall are firmly attached to form the original integrated double wall shape. Before attaching Shinbe (2-b),
Make sure that there are no inadequate connections on the outside of the single wall (2-a). The division method is effective for labor saving in mounting the outer plate (3) at a high place. The single wall is light and convenient to handle even when it is factory manufactured. This double wall can be used in both conventional frame construction method and frame wall construction method. It is a traditional Japanese style traditional and two-by-four eclectic double wall frame construction method. Make this single wall double to make it stronger by overlapping the double walls. Figure 1 Plan view and plywood (3) + studs (2-a) + plywood (1) + studs (2-
The double wall constructed in (b) is further repeated in the order of plywood + studs to select the desired number and make a strong multiple bearing wall. In the description, the structural board is the structural plywood,
Mainly, but not limited to, wood-based materials, and the same applies to studs and urethane foam resins. The construction method is the basic purpose, not the material. New products such as metals, resins, and carbon fibers, and all other new products will be positively adopted and materials will not be restricted.

[0005]

The present invention is a double-walled plate method of a wall for the purpose of satisfying high seismic resistance and high confidentiality, and is a method that can be manufactured at low cost.
The price is low, the environment is durable, the environment is comfortable, the energy is low, and the cost is low. It can be easily manufactured and has great merits according to the demand. This is a labor-saving method that is more efficient than conventional construction methods and two-by-four construction methods by making the highly earthquake-resistant construction walls into highly complete parts. For highly confidential and highly heat-insulating measures, it is rational to use the double-walled space constructed for high earthquake resistance as it is, and it is an excellent high-quality method that can be solved in one shot by short-time resin injection at the site. . Not only the vertical direction of the wall, but also the horizontal structure of the floor can be strengthened by diverting. In addition, the floor assembling method devised separately is used together to further strengthen the improvement of horizontal steel property.

[0006]

Embodiments of the present invention will be described below. It is a private house of wooden construction with a site area of 66 m ² , a building area of 49 m ² , and a ground floor of 147 m ² on the 3rd floor above ground, which is based on a newly-developed basement in 8 Higashiokyu, Arakawa-ku, Tokyo. There were many experimental elements of the invention, and all were processed on-site, but the site is small, so we will confirm the significance of the factory that was originally devised in advance. Taking a part of a building as an example, a double wall is 45m x 45x2700mm 450m on a true structural plywood 9mm (1).
The pitch was m. The studs are lined up on the foundation and plywood is combined to make a double wall with an air nailer. Prior to raising the wall, lay the bases and fix them with bolts and nuts. The structural pillar (4) and the double wall are joined together to build them up, and the braces are temporarily braced to the base. Subsequently, the adjacent walls are sequentially repeated. At the end, check the horizontal and vertical, and firmly fix it with the nails and bolts on the adjacent parallel direction and the base to build it. Pillar (4) Pillar (2-A.2-
B) When connecting the lower crosspieces (2 to a.2 to b) to the base (6), it was possible to freely damage the skeleton from the inner floor and the outer scaffold. The same procedure is repeated until the roof is built. After the completion, the outer structural plywood 9 mm (3) is entirely nailed. Partially try the single wall method to confirm that the workability is good. A hole (8) having a pitch of 450 mm and a diameter of 10 mm was formed in the true plate (1) with an electric drill as the injection and ejection holes of the urethane resin foam. At the same time, store windows, doorways, ventilation fans, and other openings. When urethane is injected, liquid starts to bubble from the bottom hole and the second hole blows out. While filling, visually inspect and repeat injection into the next hole to proceed. The foam spouts out of the nail holes, the knots of wood, and the joint gaps and fills all the gaps. The gap blocks the passage of minute air that cannot be seen visually.
After the solidification, excess metal drooping and becoming solid is easily removed with metal fittings. At the site, we will carry two foaming agent liquid drums and a machine into a two-ton truck, and extend the hose while it is still loaded until the roof is 12m high. The work amount is 45 mm in thickness, 200 m ² in wall area, and 4 artificial speeds for 2 days. The wall thickness is 90 mm, which is the same size as 4 inches of 2 x 4 inches, but the effective bearing area of the cross section of the plywood is 18 mm and the total area of the foam layer (9) is 6 inches thick wall of 2 x 6 inches. It is superior to the cross-sectional area compared to. The foamed resin used is characterized by an adhesive and compressive strength of both 3 tonnes per square meter. It will be completed at a low budget requested by the customer, and visitors will be allowed to have a sturdy structure. Highly confidential and high heat insulation, together with the hot water floor heating of the invention,
It provides a comfortable living environment that eliminates the cold of wintering, high insulation, small energy, low cost, and much more satisfying than the customer's year. The results are as described above.

[0007]

EFFECTS OF THE INVENTION By adopting the present invention, any of the conventional weak traders can make a better house in which the excellent earthquake resistance is equal to the earthquake-resistant advertisement of a specific trader such as a house maker. By using urethane foam that utilizes the space of the purpose-built earthquake-resistant, in addition to speeding up the work, you can easily make high-quality products that are highly confidential and highly insulating. Condensation does not occur on the inside of the wall, greatly improving the durability of the structural body. It is small and powerful, and has the effect of reducing the cross section of the wall to widen the room, but its performance has the rationality of firmly maintaining the effective bearing cross section.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is based on the fact that a structural plywood is sandwiched between an inner stud and an outer stud, and a double structural plywood is integrally formed by an outer structural plywood and an inner fireproof board. The present invention relates to a method of manufacturing a highly earthquake-resistant wall having rigidity.

Foaming resin is injected and filled in the gap between the true and outer sides of the wall, the compressive strength increases the impact fracture resistance, and the adhesive strength prevents the plywood from being distorted and the integral strength increases the rigidity to further increase the durability. Form an excellent wall.

In addition to the improvement of seismic resistance, the filling is a foam resin containing a large amount of still air, which has a highly confidential heat insulation, heat retention, prevention of dew condensation, excellent soundproofing effect, and quick and economical living environment.

[0004] The filling method has a multiple seismic resistant structure, which has many functions of obtaining seismic resistance without taking a wall thickness and maintaining a comfortable living environment, and has a low running cost and energy saving maintenance cost.

[0006]

2. Description of the Related Art 2 inches x 6 which is said to be strong against conventional earthquakes
Inch two-by-six and conventional construction methods are also supported by thickening the pillars. This is heavy, and the labor of the work is a burden on the Japanese people, and the room has been made smaller due to the larger cross section.

The heat insulation is mainly made of fiber such as glass wool, which is weak against dew condensation and diffusive after containing water, and internal dew condensation water damages the body. A hard urethane foam resin plate with good performance created a gap during the construction of the on-site cutting, which made it impossible to achieve high confidentiality.

As a method of scraping each of the individual materials, no method has been developed for constructing a structure having a strong endurance against earthquakes and having good airtightness.

[0009]

The expansion of the cross-sectional area for increasing the column size to increase the seismic resistance makes the room narrower and imposes a labor burden.

Although the popularity of two-by-four is rising,
There are too many legal restrictions to obtain a large opening and a large floor plan compared to the conventional construction method.

Although there are many types of building materials in the city, they are suffering from the problem of dew condensation, and both highly confidential products and industrial products depend on the technique of the site construction worker, and there are many worries about site management.

As a result of the extreme price competition, there is a tendency to emphasize the appearance of cosmetics, and the emphasis on the structural body is insufficient.

In the wall-mounted industrial drum drum flash panel system, it is impossible or inconvenient to connect the upper, lower, left and right sides, and it is anxious to build it by destroying part of it.

The one-sided plywood covering produced in the factory is heavy,
Requires heavy equipment for handling.

This is because if the structure frame of a building is emphasized, the secrecy is behind, if it is brilliant, the frame is behind, and if the secrecy is mainly, the workability of the frame is poor.

The present invention has been invented to solve these drawbacks.

[0017]

[Means for Solving the Problems] It has been confirmed by two-by-four, etc. that the single structural plywood as a building material has good seismic performance, and a structural board is provided with a gap to double the strength.

It is characterized by an integrated construction in which a foamed urethane foam is filled in the space between the plywood and the plywood to obtain adhesion, compressive strength and heat insulation performance.

FIG. 1 is a plan view of the structure, FIG. 2 is a perspective view, and FIG.
Is a front view, FIG. 4 is an exploded view of the front view, and description will be made based on these. A partial outline of the wooden axis of the wall shows the relationship between the vertical (horizontal) and horizontal crosspieces of the pillar (4) and the stud, the base (6) and the beam (7) in the front view of FIG.

It is called a double wall which is formed by sandwiching an outer stud (2-a) and an inner stud (2-b) on a structural plywood (1) which forms the center of the wall, and a nail, Use wood screws, glue, or a combination, and make the required number in advance before building.

The purpose of the double wall sandwiching the true structural plywood is
As can be seen by disassembling the plan view of FIG. 1 and the front view of FIG. 4, it can be easily fixed with nails in the direction of the arrow, and the pillar (4) and the double wall are joined with nails or the like prior to building. Or after building the pillars in place, later build a skeleton with double walls
After the double plywood (3) is joined to the outer plywood (3), the outer plywood (3) is attached as shown by a dotted arrow in FIG. 4, the building is completed, and the openings such as windows are housed.

The space of the outer plywood (3) and the true plywood (1) is a foam layer (9). Prior to filling the foaming agent, a predetermined number of injection holes are formed in the plywood (1). The holes are an injection hole and an extra spout hole, and a drill hole may be previously provided at the time of manufacturing the double wall. The whole wall is inspected and it is confirmed that there are no defects, and the resin is injected from the hole (8) with the tool nozzle of the foaming machine that is carried in, and the chemical reaction occurs in the foam layer (8) and the resin is injected from the other holes. Can be confirmed.

The construction of the double wall is the same, but the order of how to make and how to build is as follows. It is a division method with excellent speed, and the outer plywood (3) and the outer studs (2-
The outer single-sided panel of (a), the inner plywood (1), and the inner single-sided panel of the inner stud are divided into two parts to form a single wall.

As for the way of building, the pillar (4) and the outer single panel (2 to a and 3) are combined to assemble a skeleton, and the inner single panel (2 to b) is attached to the original integrated double wall. The split method is effective in saving labor for mounting the outer plywood (3) at a high place, and the single wall is manufactured in a factory and is convenient for handling.

The double wall is applicable to both the conventional frame construction method and the frame wall construction method, and is the traditional Japanese-style conventional and two-by-four eclectic double wall frame construction method.

The refractory board inside the double wall (5) is reinforced with plywood as a triple bearing wall.

The double wall is further overlapped to make it stronger.
Plan view and plywood (3) + studs (2-a) from outside
The plywood (1) + the studs (2 to b) are attached to the double wall repeatedly in the order of plywood + studs, and the desired required number is selected to make a strong multi-bearing wall.

A method of repeatedly forming a filling layer (9) and a non-filling gap layer of the foamed resin so as to have multiple functions so as to improve the function, and a method of forming the entire filling layer.

The structural board described above is a structural plywood and is mainly made of wood, but is not limited thereto. The studs and urethane of foamed resin are also the same, and the structure and method are the basic purpose and not the material. , New products such as metal, resin, carbon fiber, etc. and all other things will be positively adopted and materials will not be restricted.

[0030]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a double structure board system of a wall for the purpose of satisfying high earthquake resistance and high confidentiality, is a method that can be cheaply manufactured, and the price of a house where customers can request and place an order with peace of mind It is a person who has a cheap, durable and comfortable environment and saves energy and costs. It is a great advantage to provide a product that can be easily and easily manufactured according to the instruction of a conventional trader and that meets the customer's request.

By making the highly earthquake-resistant construction wall into highly complete parts, it is a labor-saving method that surpasses the conventional construction method and the two-by-four construction method, or has the efficiency of a composite construction. It is a rational one that uses the double-walled space that is constructed for high earthquake resistance as it is, and it is an excellent high-quality method that can be solved in one shot with a short time resin injection on site.

[0032] Not only in the vertical direction of the wall, but also in the vertical direction of the wall, it is further strengthened to improve the steel property of the floor in the horizontal direction.

[0033]

Embodiments of the present invention will be described below. Arakawa Ward, Tokyo, based on a newly designed basement, site area 66m ² , construction area 49m ² , 3rd floor above ground 147m
^In a private house of ² wooden construction, many experimental elements of the invention were used and all were processed on site, but the site is small, so the effectiveness in the original designed workshop is confirmed.

The example double wall is true structural plywood 9 mm
In (1), 45 × 45 × 2700 mm was used as a 450 mm pitch. Place the studs on the foundation, combine the plywood to make a double wall with a pneumatic nailing machine, line up the base before raising the wall, and fix it with bolts and nuts. The structural pillar (4) and the double wall are joined together to build them up, and the braces are temporarily braced to the base.
Subsequently, the adjacent walls are sequentially repeated. At the end, check the horizontal and vertical, and firmly fix it with the nails and bolts on the adjacent parallel direction and the base to build it.

When connecting the pillar (4) to the stud (2 to 2) to the base (6) and the lower bar (2 to 2) to the base (6), the skeleton can be freely damaged from the inner floor and the outer scaffold. I was able to do it without doing. The same procedure is repeated until the roof is built. After the completion, the outer structural plywood 9 mm (3) is entirely nailed.
Partially try the single wall method to confirm that the workability is good.

The urethane resin foam injection and spout holes are
Holes (8) having a pitch of 450 mm and a length of 10 mm were drilled in the true plate (1) with an electric drill. At the same time, store windows, doorways, ventilation fans, and other openings. Urethane injection starts from the bottom hole 2
Liquid foams and gushes from the second hole. While filling, visually inspect and repeat injection into the next hole to proceed. The foam spouts out of the nail holes, the knots of wood, and the joint gaps and fills all the gaps. The gap blocks the passage of minute air that cannot be seen visually. After the solidification, excess metal drooping and becoming solid is easily removed with metal fittings. At the site, we will carry two foaming agent liquid drums and a machine into a two-ton truck, and extend the hose while it is still loaded until the roof is 12m high. The amount of work is 45 mm thick
It is a total of 4 artificial speeds for 2 days with a wall area of 200 m ² .

The wall thickness is 90 mm, which is the same size as 4 inches of 2 × 4 inches, but the effective bearing area of the cross section of the plywood is 18 mm and the total area of the foam layer (9) is 6 of 2 × 6 inches.
It has a larger cross-sectional area than an inch-thick wall. The foamed resin used is characterized by an adhesive and compressive strength of both 3 tonnes per square meter.

It can be completed with a low budget requested by the customer, and the spectator can recognize its durable construction body. Highly confidential and highly heat-insulated, combined with other devised hot-water floor heating, provides a comfortable living environment that wipes out the cold of winter, and the cost of high insulation is much more pleasing than the customer's year. The results are as described above.

[0039]

The present invention is embodied in the form described above, and has the following effects.

By adopting the present invention, it is possible for a conventional contractor to create an excellent house in which super-quake-resistant ones are second to none.

With the purpose of seismic resistance, the urethane foam filling allows quick and easy heat insulation work, and makes it possible to make products of unparalleled quality.

The occurrence of dew condensation on the inside of the wall is prevented, and the durability of the structural body is greatly improved.

The wall is thin and strong, and its performance is the effective bearing cross-sectional area, which is rational to make the wall cross-section smaller and the room wider.

The highly airtight wall with high airtightness and high heat insulation has excellent sound insulation performance, and can be diverted for noise prevention only in airports, highways, high-speed railways and other areas along noise lines.
