The ridge portion of the bonding portion is protected by a sheet pile bar.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to the joining of the components of the wall of a small and simple dome-shaped house, and more particularly to the fixing structure of a plurality of inequilateral right-angled triangular panels of a fuller dome, fixing of a ridge line, and an airtight joining structure. .

[0002]

[Prior art]

Conventionally, in the case of long-term construction in emergencies or in remote areas, it can be used as a temporary inhabitant or as a warehouse or office, so it can be constructed (constructed) in a short time without requiring special tools etc. In addition, so-called prefabs (buildings) (houses) are widely used as small and simple buildings having considerable durability. The prefabricated building has a size of about 19.8 m ² (6 tsubo), and the roof and surroundings are made of metal plate, and the entrance and windows are attached to the front. There are also steel houses made of metal plates with a rather complicated structure.

[0003] However, prefabs require a large number of necessary components (parts). For example a minimum be those with 5 m ² most small in size, the roof, the side walls of the left and right and back, front wall with two windows and sliding doors, floors, requires more floor stone or the like, yet the size of the building Accordingly, the size and shape of these components change considerably, such as the necessity of windows on the side walls. As a result, it is not suitable for making emergency reserves, stockpiling, and expected production.

[0004] For this reason, a dome-shaped simple building with few such drawbacks has attracted attention.

Hereinafter, an example of the dome-shaped simple building will be described with reference to FIG.

As shown in FIG. 5, this dome-shaped building (having a roof) is basically composed of a timber frame roughly in the form of an equilateral triangle in order to reduce weight and prevent distortion. ing. In this figure, reference numeral 31 denotes wood of a predetermined length determined from the size of the building and the size of the triangle forming the dome of the building. 32 is an entrance door. 33 is a door handle. 34 is a stone stairway when entering the building. Reference numeral 35 denotes a wood contact point. At the contact points, the timber is firmly fixed to each other with metal stoppers having the necessary strength, thereby forming the framework of the building and thus supporting the dome-shaped building from the viewpoint of strength.

[0007] Then, a beam is passed between the frames, a roof is covered thereover, and a mutual machine is further arranged thereon. Then, a roofing is performed, a slate roofing, a flat metal roofing or the like is performed. A roof has been made.

However, since wood as an aggregate of a building is inferior in strength to metal, it has a thickness of at least about 10 cm and a length of 3.6 m or more. For this reason, there is considerable weight, and considerable labor is required for transportation and handling, and it is necessary to accurately build the foundation of the building. Furthermore, wood is quite expensive, and it takes time to store it in terms of moisture resistance, fire resistance and corrosion resistance. Difficult to reuse. And, of course, if it is made of metal bones, welding and special jigs and tools may be required for its connection, which is unsuitable as a simple building.

For this reason, the inventor of the present application has proposed an invention regarding a full-dome type simple building as shown in FIG. 6 in Japanese Patent Laid-Open No. Hei 10-282274.

As shown in FIG. 7, a fuller dome is conceptually a sphere formed by combining a plurality of types of regular polygons of a soccer ball, and in many cases a regular pentagon and a regular hexagon. It is a widely known fact that it can be composed, but it refers to a dome-shaped building constructed using this property of figures. In this building, a metal beam is provided at a portion corresponding to the side of the triangle obtained by dividing the regular polygon, and the beam bears the strength.

However, simply doing so is not suitable as a simple building as described above. For this reason, the inventor of the present application firstly divided the two types of regular polygons on the wall surface (dome membrane) of this building into isosceles triangles connecting the center and each side, as shown in FIG. As shown in the figure, this isosceles triangle is further divided into two types of right triangles having the same side (vertical side) sandwiching the right angle, and the right triangle is manufactured by a thin metal plate panel, and its peripheral portion is formed. Bent to act as a beam or bone. As a result, since it is a right-angled triangle that is originally line-symmetric, using a metal sheet that has been cut into a right-angled triangle upside down and using only one kind of material is sufficient.

In addition, apart from forming notches such as entrances and floor materials or windows for daylighting, the whole building has two types of regular polygons forming the dome, ie, two types of panels in principle. It is all that is needed.

FIG. 8 shows this relationship when the regular polygon is a regular hexagon. In this figure, (a) shows a state in which right-angled triangular panels 71 and 72, which are symmetrical with each other, are cut out from one plate, and (b) shows an equilateral triangle formed by combining two right-angled triangle panels. It shows how to do. In FIG. 7A, the peripheral portions 73 of two right-angled triangles are portions that bend as described above and perform the function of a beam.

In FIG. 2B, both ends 74 of the hypotenuse of the right-angled triangle panel or each vertex of the equilateral triangle are cut out in a slightly round shape. This is done in the context of the present invention, which will be described later.

Second, the right-angled triangular panels are joined to each other by temporarily bonding the bent peripheral portion with a double-sided tape or the like, and then using a normal metal fastener such as a bolt.

[0016] Furthermore, the dome-shaped building is lightweight and does not require labor or special jigs for transportation and assembly.

[0017]

[Problems to be solved by the invention]

 First, when assembling a right-angled triangle panel, many right-angled triangle panels are assembled at the center and the top of a regular polygon, but the fixtures and structure of this part pose a problem. That is, six right-angled triangle panels are gathered at the center of the regular polygon, which is twice the number of corners, and at each vertex, three regular polygons share the vertex. Further, in a dome-shaped building, these panels are not a flat group but a three-dimensional structure having a certain angle (tilt) with respect to each other.

For this reason, there is a problem that these many panels can be easily and firmly connected without using any special machine, tool or the like, and also ensure waterproofness and fireproofness.

Second, the connection of the sides of the right-angled triangle panels to each other is problematic.

Also, since each panel has a certain angle to each other, it is necessary to connect easily and firmly without using any special machine or tool, and to secure waterproofness, fireproofness, etc. is there.

In response to these requests, the inventor of the present application has given a tentative solution in the above-mentioned invention, and has disclosed it.

However, in recent years, it is possible to rapidly build a large number of buildings even in an emergency such as an earthquake or a large fire. In many remote areas, weather conditions are poor. After a large earthquake, there may be considerable aftershocks. Demands for high strength and water resistance are increasing.

In addition, even in the extreme case, even a non-technical engineer is required to be able to construct easily even an amateur.

Also, in the case of mass production in an emergency, some irregularities may occur in the products, and in transportation to remote areas, etc., the products may be slightly distorted. There is also.

For this reason, there has been a strong demand for the development of a technique that satisfies such a demand.

[0026]

 The present invention has been made to solve the above problems.

In order to achieve this object, in the present invention, in a portion where a large number of panels are gathered, flanges are arranged above and below the portion, and both flanges are suppressed by bolts and nuts. I am trying to fix it.

At the peripheral portion of the panel, a U-shaped or V-shaped connecting rod and a tapping screw are used to fix the panel.

In any of the above cases, the temporary bonding and the airtightness and liquid tightness of the building are achieved by a soft adhesive such as a double-sided adhesive tape.

Further, bolts and the like to be used are considered to contribute to rapid construction and structural reinforcement.

With the above configuration, the following operation is performed.

This is a joint structure of a portion where right-angled triangular panels of a fuller dome type simple building are assembled, and it is premised that the right-angled triangular panels are slightly notched at both ends of the oblique side for inserting fixing bolts. It is an assembly part hole formation type panel.

In principle, the upper flange made of metal having a thickness of about 0.6 to 2.3 mm has a shape protruding toward the outside of the building corresponding to the angle between the right-angled triangle panels. .

The fixing bolt is 6 mm or more, preferably 8 mm or more from the strength side, and its head is firmly fixed to the inner surface (building side) of the center portion of the upper flange by welding or bonding and attached. ing.

The lower flange has a convex shape toward the outside of the building corresponding to the angle between the right-angled triangle panels, and has a through hole for the body and screw portion of the bolt at the center. Shape.

As for the nut corresponding to the fixing bolt, the fixing bolt is inserted from the outside (side) of the building into the hole formed in the right triangular panel assembly, and a lower flange is further added to the inserted fixing bolt. After fitting from the inside (side), tighten the right triangle panel of the collecting part via the upper flange and lower flange, and of course, if necessary, also with washers.

[0039] The soft adhesive is supplied from the outside of the building at a stage where the fixing bolt is inserted into the hole formed in the right triangular panel gathering portion from the outside of the building and the upper flange of the right triangular panel of the gathering portion. Temporarily adheres to the bottom surface, and is airtight and waterproof when the building is used.

In the invention according to claim 2, the joint structure of the full-dome type simple building having the eyebolt, the upper adhesive means, the upper flange, the lower flange, the nut, and the soft adhesive at the portion where the right triangular panels are gathered. Wherein the right-angled triangle panel is a collective-hole-formed panel in which both ends of the hypotenuse are cut off, and an upper flange is formed to project outward corresponding to an angle between the right-angled triangle panels. It has a shape and an opening with a hole of an appropriate diameter for penetrating the eyebolt at the center, and the lower flange is convex to the outside corresponding to the angle between the right-angled triangle panels and is formed at the center. The eyebolt has a shape in which an opening for penetrating the eyebolt is opened. The eyebolt has a head portion facing the outer surface of the building, a central hole of the upper flange, and a panel assembly of the right triangle. The hole formed and the central hole of the lower flange are passed through in this order and attached, and thereafter, the right-angled triangle panel of the collecting portion is joined together with the nut via the upper flange and the lower flange. The upper bonding means is provided with the eyebolt inserted into the center hole of the upper flange, and both are temporarily (in the case of packing or the like) or are permanently bonded (in the case of welding), and together with the hole. The nut is of a size corresponding to the eyebolt, and the eyebolt is formed in the center hole of the upper flange and the hole formed in the right triangular panel gathering portion. Is screwed into the eyebolt while being inserted from the outside of the building through the hole of the lower flange inside the building, thereby tightening the three members. When the upper flange is attached to the right triangular panel gathering portion with the holes at both center portions aligned with each other, the soft adhesive material is applied to the surface of the right triangular panel of the gathering portion on the exterior side of the building. And the lower surface of the upper flange are temporarily bonded together to form an airtight and waterproof structure, which is a joint structure of a portion where right-angled triangular panels of a full-dome simple building are assembled. .

With the above structure, in the joint structure having the eyebolt, the upper bonding means, the upper flange, the lower flange, the nut, and the soft adhesive at the portion where the right-angled triangular panels of the full-dome simple building gather, Functions and effects are exhibited.

The right-angled triangular panel is a panel having a hole formed at a collecting portion, with both ends of the hypotenuse cut out.

The upper flange has a shape protruding outward corresponding to an angle formed between the right-angled triangle panels, and a shape having the hole for penetrating the eye bolt at the center.

[0044] The lower flange has a shape protruding outward corresponding to an angle formed between the right-angled triangle panels, and has a shape in which the eyebolt through-hole is opened at the center.

The eyebolt passes through the center hole of the upper flange, the hole formed in the right triangular panel assembly, and the center hole of the lower flange in this order, with the head of the eyebolt as the outer surface of the building. After that, the right triangle panel of the collecting portion is fastened together with the nut via the upper flange and the lower flange.

The upper bonding is performed independently of the upper flange and the eyebolt, such as a rubber packing-like soft material or a double-sided adhesive tape, or integrally with the upper flange and the eyebolt such as a welded portion or a build-up metal by welding. The means adheres the eyebolts in a state where the eyebolts are inserted into the center holes of the upper flanges, and also achieves airtightness and waterproofness.

The nut is of a size corresponding to the eyebolt, and the eyebolt is inserted from the outside of the building through the center hole of the upper flange and the hole formed in the right triangular panel assembly. Then, it is screwed into the eyebolt while penetrating the hole of the lower flange inside the building.

When the upper flange is attached to the right-angled triangular panel collecting portion with the holes at both center portions thereof aligned with each other, the soft adhesive material is provided on the right side of the right-angled triangular panel of the collecting portion at the outside of the building The lower surface of the upper flange is temporarily bonded, and airtight and waterproof.

According to a third aspect of the present invention, the soft adhesive has at least one of a double-sided adhesive tape and a waterproof packing made of neoprene rubber, plastic, or the like.

With the above configuration, the following operation is performed.

The soft adhesive is preferably a thick double-sided pressure-sensitive adhesive tape or a soft and weather-resistant material which is preferably used in combination with a pressure-sensitive adhesive tape or an adhesive in view of the play of the folded portion. It has at least one of the waterproof packings. In this way, temporary bonding of right-angled triangle panels during building construction and liquid-tight and air-tight maintenance during building use are performed.

In addition, the vibration of the membrane surface due to rain, wind, and ground (after-shock) is prevented, and the sound of rain and external sound is cut off.

In the case of a thick member, the backlash of the steel member is absorbed.

In addition, since almost the entire surface is covered with metal, nonflammability is naturally achieved.

[0055] In the invention according to claim 4, the peripheral structure of the right-angled triangle panel of the full-dome simple building is connected to each other, and the right-angled triangle panel is connected to the inside of the building. A peripheral-joining type panel which is bent to the side and has a hole for inserting a tapping screw at a bent portion thereof (to the lower side), wherein a portion existing between the bent portions of the two right-angled triangle panels to be bonded is: U-shape or V-shape: a part that is bent downward around the periphery of the panel, and a shape that allows the panels to be joined in response to the fact that each panel has an angle to each other. Includes U-shape and trapezoid with narrow lower side (but no upper side).部分 The portion of the panel located on the outside of the building on both sides is made of a thin steel plate or a soft metal such as aluminum or copper bent along the panel surface from both upper ends of the U-shaped or V-shaped portion. And a high-strength plastic or FRP-shaped joining rod, and temporarily bond the side of the joining rod to the bent part of the right-angled triangle panel, and also a soft adhesive material that is airtight and waterproof when used in buildings. The joining rod and the right-angled triangle panel were temporarily bonded with a soft adhesive, airtight and waterproofed, and then screwed into the tapping screw insertion hole in the bent part of the right-angled triangle panel. A self-tapping screw for mechanically and firmly fixing the joining rod and the right-angled triangular panel to each other; a both end located between the bent portion existing on the outer surface of the joining panel and the outer surface of the panel; On the part side It is characterized by having a sheet pile-shaped rod made of thin metal or the like to protect from outside bonding bar and location.

With the above configuration, the following operation is performed in the joint structure between the peripheral portions of the right-angled triangular panels of the full-dome simple building.

In the right triangle panel, the peripheral portion to be joined is simply bent downward or in a U-shape toward the inside of the building, and the portion bent downward, and if the U-shaped bend, is directed downward. This is a panel that can be joined to the peripheral part and has a hole for tapping screw insertion at a prescribed pitch in part.

The connecting rod has a U-shaped or V-shaped (including, inclusive of) a portion existing between the downwardly directed portions of the bent portions of the two right triangle panels to be bonded. The portions located on the outer surfaces of the panels on both sides are bent along the panel surface from both upper ends of the U-shaped or V-shaped portions.

The soft adhesive material temporarily bonds the side surface of the joining rod and the bent portion of the right-angled triangular panel, and at the same time, provides airtightness and waterproofness. It also mediates the joining of the two right triangle panels.

The tapping screw has a length of about 4 mm to 6 mm. After the joining rod and the right-angled triangular panel are temporarily bonded with the soft adhesive material and airtight and waterproofed, the right-angled triangular panel is bent. It is screwed in by using a screwdriver or a screwdriver from the tapping screw insertion hole in the provided part, and the joining rod and the right-angled triangle panel are mechanically and firmly fixed.

In principle, the sheet-like bar made of a thin metal plate having a thickness of about 0.4 to 0.8 mm has both ends located between the bent portion existing on the outer surface of the panel and the outer surface of the panel. It is located on the outside of the building to protect the connecting rod.

The soft adhesive has a double-sided pressure-sensitive adhesive tape having strong adhesive strength and durability.

The invention according to claim 4 is characterized in that the soft adhesive has a double-sided adhesive tape which is easy to handle and obtain. When the U-shaped bar is made of plastic or the like, it is a matter of course that measures (such as selection of material) are taken to make the adhesive strength appropriate.

According to the above configuration, the same operation as the device of the third aspect is performed.

[0065]

[Embodiment of the invention]

 Hereinafter, the present invention will be described based on its embodiments.

(First Embodiment) FIG. 1 shows a state of joining of a portion where a right-angled triangular panel of a small fuller dome type building shown in FIG. 7 invented by the present applicant is assembled. It is a diagram of a cross section orthogonal to the building wall surface (membrane) of this part.

FIG. 2 is a diagram of a plane parallel to the building wall of that part. FIG. 3 is a cross-sectional view perpendicular to the wall of the building, showing a state of joining the sides (ridges) of the right-angled triangle panel.

First, a description will be given of the joining of each panel at the portion where the vertices of a large number of right triangle panels are gathered, that is, at the center and vertices of a regular polygon.

In FIG. 1, reference numeral 1 denotes an upper (outer side) surface of a right triangle panel. 2 is a cross-section of the edge around the right triangle panel and the portion where the ridge line of the dome is bent downward (inside the building) from the strength and joint surface. This situation is shown in the sectional view taken along the line AA in FIG. Reference numeral 3 denotes an upper flange that covers a gathered portion of a number of panels from above. 4 is a bolt. 5 is a double-sided adhesive tape. Reference numeral 6 denotes a heat insulating / sound insulating material made of, for example, a polyurethane foam foamed at a factory in advance. Reference numeral 7 denotes a polyurethane foam cover plate. 8 is a lower flange. 9 is a spring washer. 10 is a nut.

FIG. 2 is a view of a portion where the triangular panels are assembled viewed from outside the building wall, that is, corresponds to the plan view of FIG. In this figure, the same components and parts as those in FIG. 1 are denoted by the same reference numerals.

Hereinafter, each unit will be described.

The upper flange, which is used for the set of triangular panels at the center of the regular polygon, has the same regular polygon shape as that of the set of right triangular panels at each vertex of the regular polygon. The shape used is a regular hexagonal shape, and in any case, it is previously bent at a factory along a ridge line such as a regular polygon.

That is, since each regular polygon forms the wall surface of a dome-shaped building, the center of each regular hexagon (and also the regular pentagon) has a shape slightly protruding to the outside of the building from its peripheral part. ing. Therefore, the faces of a regular (or isosceles in the case of a regular pentagon) triangle consisting of two adjacent vertices have some angle with each other, and thus the upper flange and the lower flange of the pair also have these angles. It has a shape and structure that is bent in a convex shape along the ridgeline of the equilateral triangle.

In the portion where the three regular polygons are gathered, not all of the two pairs or the like but all of the six right-angled triangle panels have a certain angle with each other. Each of these right-angled triangle panels has a shape and structure that is bent in a convex shape along the ridge line.

The bolt is made of steel in terms of cost, strength, etc., and its head is fixed to the lower surface of the upper flange by welding at a factory. The length of the panel corresponds to the part of the panel facing downward.

From the viewpoint of workability, the double-sided pressure-sensitive adhesive tape is preferably a circular or hexagonal sheet having a round hole in the center in advance, but may be a thin and rectangular one notched.

The spring washer serves to prevent the nut from loosening. The nut is, of course, paired with the above-mentioned bolt, but is preferably made of a material different from that of the bolt, such as copper alloy or SUS, in order to prevent sticking due to rust or the like.

Now, after temporarily fixing the U-shaped bent portion at the peripheral end of the right-angled triangular panel using a double-sided adhesive tape or the like, the upper panel, the lower flange, bolts, nuts, etc. are used to fix each panel. Is fixed.

In this procedure, at the center of the regular hexagon, where the vertices of the twelve right-angled triangular panels converge, as shown in FIG. There is a slight cutout. Therefore, the vertex of the right triangle panel has a round hole at the center of the regular polygon or the vertex of the regular polygon.

First, a double-sided adhesive tape is attached around the entire upper surface of the round hole. Alternatively, adhesive tape is used as such for temporary fixing of right triangle panels. After that, a mushroom-shaped bolt with a large umbrella, whose head is fixed to the lower part of the upper flange by welding, is inserted from the outer wall side of the building into the hole in the panel assembly.

Next, inside the building, the lower flange is fitted into a bolt inserted from the outside from below, and a washer is further fitted to prevent loosening, and then tightened with a nut.

Thus, the fixing of the panel assembly is completed.

Under this condition, the triangular panels are fixed to each other by the pressing force from the upper and lower flanges and the fitting of the upper and lower flanges by folding along the regular polygonal ridges. Will be done. At this time, since the upper and lower flanges have a thickness of about 0.6 to 2.3 mm, they can be pressed and have sufficient strength.

The liquid tightness between each panel and the upper flange in the panel gathering part and the water and rain resistance of the panel gathering part of the dome are secured by double-sided adhesive tape. Will be done.

At this time, the double-sided pressure-sensitive adhesive tape has a thickness of 0.1 mm or more, preferably 0.5 mm or more, or a laminate of a plurality of sheets or a waterproof cloth interposed therebetween. In this way, the play between the triangular panels and the upper flange and the slight irregularities in the bent portions of each panel are absorbed.

Further, at this time, since the upper flange and the upper surface of the panel do not come into direct contact with each other, the paint on the panel may be damaged due to rubbing between metals due to wind or vibration caused by an earthquake, or the like. There is no danger such as corrosion of the panel.

Next, the joining of the right-angled triangular panels at the edges or at the peripheral portions of the panels will be described.

In FIG. 3, the same components and parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. Reference numeral 11 in the drawing is a sheet pile bar. 12 is a U-shaped stick. 13 is a tapping screw.

The sheet pile is manufactured by bending a thin metal plate such as a tin plate. In the present embodiment, the U-shaped bar is a thin steel plate or a thin plate of copper or aluminum. Wood is not used for its corrosion resistance.

First, the temporary fixing will be described.

The U-shaped stick has double-sided adhesive tapes attached to both outer surfaces. Then, the two panels are glued to the downward-facing portions of the two right-angled triangular panels on both sides thereof, which are bent in a U-shape, thereby indirectly connecting the two panels to each other. Temporarily fix.

Next, for permanent fixing, a hole slightly larger than the diameter of the tapping screw is previously opened at a factory at a predetermined position on the side wall surface of the bent portion around the right-angled triangular panel. A self-tapping screw is screwed into the U-bar, and the U-bar and the two panels on both sides are firmly fixed. The use of self-tapping screws instead of bolts and nuts here means that no special tools are required to screw them into the metal, and that nuts that can be dropped down when working at high altitudes if not a professional craftsman That is to avoid.

At this time, the bent portion of the above-mentioned bar-shaped bar is fitted between the lower portion of the upper flat surface of the U-shaped bar and the upper surface of the right triangle panel. This prevents rainwater from entering the outside of the U-shaped portion of the U-shaped bar by the action of the double-sided adhesive tape.

Now, the function of the double-sided pressure-sensitive adhesive tape is that the surface where the right-angled triangular panel and the U-shaped bar are in contact with each other can be left with a gap even if fixed with tapping screws. The gap is eliminated by the elastic deformation of the tape, and at the same time, the airtightness of this portion is maintained, and at the same time, waterproofness and moistureproofness are obtained.

It is needless to say that the diameter and pitch interval of the tapping screws are appropriately selected according to the size of the building, the purpose of use, the period of use, and the like.

(Second Embodiment) This embodiment is different from the first embodiment in that a large number of right-angled triangular panels are joined together and fixed to the upper flange by fastening the upper flange and the lower flange. The difference is that a separate bolt is used, while a separate bolt is used.

FIG. 4 shows this state. In this figure, reference numeral 41 denotes an eyebolt. 51 is a packing.

[0098] As described above, when a full-dome type building is constructed using eyebolts, a film surface such as a regular polygonal shape, which is not necessarily lightweight, is used by using the eyebolts, for example, by using a vehicle-mounted crane. It can be lifted.

For this reason, it is possible to assemble a large number of right-angled triangular panels in the form of a regular polygon on the ground in advance, and it is possible to build more quickly and in large quantities in an emergency such as an earthquake.

Next, after a major earthquake, there is a tendency for aftershocks with a very large seismic intensity, and winds tend to be strong in remote areas such as polar and desert areas near the top of alpine mountains. However, by connecting the piles and eye bolts that have been separately driven into the ground in advance with ropes, sufficient reinforcement of the building can be achieved. This not only greatly contributes to the mental stability of people living in the dome, especially after a major earthquake, but also makes it possible to use ropes to dry wet or laundry. .

In the present embodiment, the eyebolt and the upper flange are separated from each other. However, it is needless to say that the eyebolt and the upper flange may be fixed in advance by welding at a factory and air-tight (liquid) tight. In particular, this is preferable when hanging with a crane or the like.

Although the present invention has been described based on the embodiments, it goes without saying that the present invention is not limited to these embodiments. That is, for example, the following may be performed.

1) The heat insulating material on the lower surface (inside the room) of the right triangle panel is made of glass wool or sheet in a thin vinyl sheet in order to prevent scattering of the broken fine core wire from the viewpoint of cost. Glass wool with a protective film.

Further, glass wool wrapped with aluminum foil is used to improve fire resistance and reduce costs.

Alternatively, a styrofoam plate or sheet is used.

2) A V-shaped rod is used for joining the edges of the right triangle panel.

3) The both ends of the peripheral portion of the right-angled triangle panel are not bent in a U-shape but are simply planes without bent portions. (Accordingly, in this case, the bolt is screwed down to near the head.) 4) The bend around the right-angled triangular panel is not U-shaped. It is simply bent downward for ease.

5) As shown in FIG. 4, in the U-shaped bending, the upper and lower corners are rounded with a radius of about 5 mm to absorb backlash and irregular length of the bent portion.

6) Double-sided adhesive tape is also used on the upper surface of the lower flange and the lower surface of the U-shaped bent portion of the panel to further absorb backlash and irregular lengths.

7) An adhesive such as araldite or another material such as a wire is used as necessary. 8) Aluminum foil, which is also used for food packaging, is used as a polyurethane foam cover plate.

9) By further attaching a weather-resistant single-sided adhesive tape from the outside of the sheet pile bar, further corrosion prevention is achieved.

[0112] 10) The present invention is also applied to the joining of right-angle portions where four right-angled triangular panels are gathered. (Accordingly, in this case, notches for forming holes for bolt penetration are provided at all three vertices of the right triangle panel.)

[0113]

[Effect of the invention]

 As described above, according to the present invention, the upper flange and the lower flange are manufactured separately from the panel as a fixture for the gathered portion of right-angled triangle panels such as the center of a predetermined regular polygon, Further airtightness and water resistance can be ensured, and strength is also obtained.

Further, a sheet-like bar is used to join the ridges of the right-angled triangular panel, and a thick double-sided adhesive tape is inserted between the U-shaped bar or V-shaped bar and the right-angled triangular panel. It has good waterproofing, waterproofing properties, etc. In addition, by inserting polyurethane or styrofoam material on the back side of the panel with adhesive, etc., the vibration-proof effect, heat-insulating effect, and sound-insulating effect are great.

Most parts can be reused except for some parts such as a double-sided adhesive tape. (The joining rod can also be reused by changing the position of the tapping screw.

Further, since steel parts and the like are connected via a double-sided adhesive tape or the like, some looseness and irregularity of the parts can be absorbed at the time of construction, which is suitable for mass production in an emergency.

Further, welding, a crane, electric power, and the like are convenient at the construction site, but are not indispensable, so they are suitable for construction in an emergency or in a remote place.

In addition, since no particularly complicated tools and parts are used, construction is possible even without a specialized engineer or craftsman.

Further, when the eyebolt is used to fix the right-angled triangle panel, it can be used for suspending when a crane can be used for lifting the building membrane surface at the time of construction. It becomes very easy.

Also, since it can be used to reinforce a building, the flexibility and use in building and using a fuller-dome type building are expanded accordingly.
