The present invention relates to a metal triangular panel which is a member constituting a dome-shaped building, a dome-shaped building constructed using the same, and a method for constructing the dome.

Conventionally, dome-shaped buildings have been built as temporary houses in emergency or remote areas, and have been used as small-scale houses. In general life, a large number of dome-type structures such as multi-purpose halls are infiltrated.

The dome-type building is generally called a fuller dome or a geodesic dome. As a structure, there is a structure in which a steel frame is arranged radially from the top of the dome to construct a circular dome frame. However, there are problems such as the use of many components of the dome and a long construction period due to the complexity of the building process.
Therefore, a technique for constructing a dome-shaped building using a wooden panel has been disclosed as a solution to the problem of the steel structure. For example, as in Patent Document 1, a wooden triangular panel is used as a constituent member, a wooden polygon panel is formed, and the dome-shaped building is constructed by combining the polygon panels.

According to such a known technique, since a dome-shaped building is constructed by combining panels, the construction process can be omitted and the construction period can be shortened compared to the case where a framework is constructed. Further, the number of components can be reduced, and the construction cost can be reduced and the construction can be facilitated.
Moreover, the prior art of the following patent document 2 and the patent document 3 is disclosed as a prior application by the same applicant as this application.

It is a member used to join the frame member 2 and the purlin 5. The gusset plate 3 and the frame member 2 are fixed by welding, and the main building 5 is fastened with a nut by inserting a bolt into the hole 4. Moreover, when the frame material 2 and the gusset plate 3 are fixed by welding, the gusset plate 3 having a shape that facilitates welding may be used. In addition, the bolt nut 7 is a bolt and a nut, and should just be able to be inserted in a hole and to fasten members. Moreover, it uses for description by separate description like a volt | bolt and a nut.

The main building 5 is a structural member that supports the base plate 8. The purlin 5 propagates the load of the base plate 8 to the frame material 2. The purlin 5 has holes formed at the periphery of both ends. Bolts are inserted into holes formed in the peripheral portions at both ends, fastened with nuts, and connected to the gusset plate 3. Moreover, the main building 5 should just be a member which can support the base plate 8 and can be connected with the gusset plate 3, and the shape of the main building 5 is not limited. For example, what is necessary is just to be shape | molded in the shape which has the surface which can support the base plate 8, and the surface which can be joined to the gusset plate 3. FIG.

The plate 6 is a steel plate used for joining components. The plate 6 is fixed to the frame by welding. It is a member used to join the frame member 2 and the base plate 8 relating to the frame. It is a plate-like member having a shape that allows the frame body constituted by the inclined frame member 2 and the field plate 8 having a planar shape to be joined.

The field board 8 is a part of the roof member, and is a member that supports the finishing material of the roof. The field board 8 may be a structural plywood that is a plywood used as a structure that supports a structure of a building. Alternatively, a fire-resistant field board 8 such as a fire-resistant wood wool cement board may be used. Further, the field plate 8 may be a single triangle.
The field board 8 is supported and fixed by the main building 5 and the plate 6. For example, holes may be formed at predetermined locations on the purlin 5, the plate 6, and the base plate 8 and fastened with screws or the like.

The finishing material 10 is a part of the roof member, and is a surface member that constitutes the exterior of the triangular panel 1 and the dome-type building. The finishing material 10 is plate-shaped, and is fixed to be coated on the outer surface of the field board 8. For example, the outer front portion of the base plate 8 is covered with the finishing material 10, a hole is formed with a drill or the like, and they are fixed to each other with the screws 9. The screw 9 is tightened in the hole with a tapping screw or the like.
The finishing material 10 may be a thin plate steel plate made of metal or a slate obtained by processing slate into a thin plate shape. When the finishing material 10 is a steel plate, it is a thin steel plate having a thickness of about 0.4 mm and may be a galvalume steel plate.

Next, the Example which forms the triangular panel 1 using the structural member which concerns on the triangular panel 1 is demonstrated.
First, arrangement | positioning of the frame material 2 which comprises a frame is demonstrated.
FIG. 2 is a view showing the shape of the frame body of the triangular panel 1 constituted by the frame material 2 and the arrangement of the frame material 2 constituting the frame body.
Fig.2 (a) is the figure which showed arrangement | positioning of the frame material 2 which comprises a frame. A gusset plate 3 is fixed to the frame member 2 constituting the two sides of the triangular frame. The gusset plate 3 may be either fixed to the frame member 2 after the frame is formed, or formed to be fixed to the frame member 2 in advance.
FIG. 2B is a view showing a predetermined portion or a cross section of the frame. The AA ′ cross section is a cross section of the frame member 2 constituting the two sides of the frame. The BB ′ cross section is a cross section of the frame member 2 to which the gusset plate 3 is fixed. The C range is a range around the apex of the triangular frame. Further, when forming the triangular frame body, the frame member 2 is configured such that two opposing faces of a substantially U-shaped shape are positioned in the inner direction of the triangle.

Next, the inclination of the frame member 2 related to the frame will be described.
The frame body is formed by inclining the frame material 2 and arranging it in a triangular shape and fixing the frame materials 2 to each other by welding. This inclination is an inclination from the vertical direction, and the vertical direction is a vertical direction with respect to the horizontal direction.
FIG. 3A is a cross-sectional view of the frame member 2 constituting the frame, and is a view showing a cross section taken along the line AA ′ in FIG. The frame member 2 is arranged with the frame member 2 inclined so that the surface constituting the frame body side surface forms a slope in the frame member. Moreover, all the three side surfaces which concern on a triangular frame are formed in the slope. That is, the three frame members 2 forming the triangular frame body are all inclined.

For example, it is assumed that the side surface of the frame body forms a slope inclined at an angle θ from the vertical direction. This is a case where the frame body 2 is formed by inclining the frame material 2 so that the surface of the frame material 2 constituting the side surface of the frame body has an inclination angle θ.
Moreover, since the frame material 2 is substantially U-shaped, two opposing surfaces other than the surfaces constituting the frame body side surface related to the frame material 2 extend in a direction having an angle from the horizontal direction. If the frame member 2 has a substantially U-shaped shape at a right angle, in the horizontal direction, the two opposite surfaces other than the surfaces constituting the side surfaces of the frame body are inclined at the elevation angle θ.

Next, fixation by welding of the gusset plate 3 and the frame member 2 will be described.
FIG. 3B is a diagram showing the shape of the gusset plate 3. FIG. 3C is a cross-sectional view taken along the line BB ′ in FIG. 2B and shows a portion where the gusset plate 3 is fixed to the frame member 2.
In the gusset plate 3 and the frame member 2, the peripheral portion of one end of the gusset plate 3 is fixed to the portion surrounded by the substantially U shape of the frame member 2 by welding. Since the gusset plate 3 is a substantially V-shaped planar plate member, a part of the gusset plate 3 protruding from the frame member 2 can protrude in the horizontal direction. This is because the frame member 2 constituting the frame body depends on the inclination angle and the substantially V-shaped angle of the gusset plate 3. Note that the angle at which the frame member 2 is inclined and the angle at which the gusset plate 3 is formed into a substantially V shape need not be specified. In the triangular panel 1 according to the present invention, it is only necessary that the side surface of the frame body is an inclined slope, and a part of the gusset plate 3 protruding from the frame material 2 due to fixation extends in the horizontal direction.

Next, fastening of the purlin 5 and the gusset plate 3 will be described.
FIG. 4A is a diagram showing the arrangement of the purlin 5. The gusset plate 3 fixed to the frame member 2 by welding and the purlin 5 are fastened and fixed by bolts and nuts. FIG. 4 (b) is a diagram showing fastening portions of the frame member 2, the gusset plate 3, and the purlin 5. FIG.4 (c) is drawing which expanded D range in Fig.4 (a).
The gusset plate 3 fixed to the frame member 2 is arranged to be a pair of opposed positions. The purlin 5 is fastened to the pair of gusset plates 3. Holes for inserting bolts are formed in the peripheral portions of both ends of the purlin 5. Thereby, a bolt is inserted in the hole formed in the gusset plate 3 and the purlin 5 and fastened and fixed by the nut. The purlin 5 fastened to the gusset plate 3 is disposed at a position where the purlins 5 are parallel to each other. Further, when the lower side in FIG. 4 is referred to as a bottom side and described, the triangle-shaped bottom side and the purlin 5 are arranged in parallel positions. That is, the gusset plate 3 is paired at a position parallel to the bottom and is fixed to the frame member 2.

Next, fixation of the frame material 2 and the plate 6 will be described.
FIG. 5A is a diagram in which the plate 6 is arranged on the frame member 2. The plate 6 is arrange | positioned in the surface by the side of the outer surface of the roof which concerns on the frame material 2 which comprises a frame. Moreover, it adheres to all the three frame materials 2 which comprise a triangular frame.
The frame material 2 and the plate 6 may be either fixed by welding, or may be formed by forming holes and fastening by bolts and nuts.

FIG. 5B is a cross-sectional view taken along the line EE ′ in FIG. 5A, showing a cross section of a portion where the frame member 2 and the plate 6 are fixed.
The plate 6 is a biplanar plate-like member, and is formed by bending so that the opposite angles of the two planes have an obtuse angle. Further, the surface of the plate 6 that protrudes from the frame member 2 toward the inner side of the triangle protrudes so as to form a horizontal plane. In the plurality of plates 6 fixed to the frame, any protruding surfaces are on the same plane. Further, a part of the plate 6 that projects from the frame member 2 toward the inside of the triangle is a wing member that receives the path plate 8.
This is because the two opposing surfaces related to the frame material 2 are formed in a direction having an angle from the horizontal direction by arranging the frame material 2 related to the frame body to be inclined. When fixing a field plate 8 to be described later, in a frame having an inclination angle and an elevation angle by the frame member 2, it is not stable to support the field plate 8 having a planar shape. Therefore, a member having a structure in which the frame body receives the path plate 8 on the same plane is necessary.

Next, arrangement | positioning of a roof member is demonstrated.
FIG. 6 is a diagram in which the field plate 8 is arranged on the frame. The screw 9 is illustrated for illustration and is not limited to the arrangement according to FIG. Moreover, although the example using the four field boards 8 was shown, this invention is not limited to this. The field board 8 is supported by the main building 5 and the plate 6.

FIG. 6B is a diagram showing the arrangement of the finishing material 10 constituting the outer surface portion of the triangular panel 1.
A plate-like finishing material 10 is arranged and fixed parallel to the bottom side of the triangular panel 1. In the finishing materials 10, a partially overlapping portion is formed. For example, there is a joining method called goby bonding or goat fastening.
In this case, the overlapping part is formed concentrically from the center of each polygon formed by the triangular panel 1. However, the present invention is not limited thereto, and a portion where the finishing material 10 overlaps may be formed on a line parallel to the oblique side of the triangular panel 1. At this time, all the overlapping portions are formed concentrically around the top of the dome-shaped building.
In any case, the finishing material 10 disposed and fixed on the top side of the dome-shaped building forms the outer surface of the overlapping portion. Thereby, water flows smoothly from the water surface to the water surface, and water does not enter.

The triangular panel 1 according to the present embodiment is formed by having the configuration described above.

Next, the case where several types of frames are formed by combining the frame members 2 related to the frame will be described. Further, several types of triangular panels 1 are formed by several types of frames. Further, a polygon formed by a plurality of types of triangular panels 1 will be described.

The frame constituting the triangular panel 1 is formed in an isosceles triangular shape by two types of frame members 2 having different lengths. Moreover, the frame material 2 which comprises two equal sides of an isosceles triangle shape is arrange | positioned at the same inclination.
In detail, the frame material 2 which comprises two equal sides which concerns on an isosceles triangle is formed in the arrangement | positioning at the same inclination. Further, in the frame member 2 that forms one side different from the isosceles side, the frame member 2 is disposed at an inclination angle different from the inclination of the frame member 2 that forms the isosceles side.

The polygonal body formed by the triangular panel 1 is of two types, a pentagonal body and a hexagonal body. For this reason, the triangular panel 1 requires different combinations of side lengths and inclination angles related to the isosceles triangular frame.
Here, the description will be made by defining the frame material 2 as a meaningful frame material including the length of the frame material 2 and the inclination angle when forming the frame body. For example, the first frame member 2a, the second frame member 2b, the third frame member 2c, the fourth frame member 2d, and the fifth frame member 2e are defined depending on the length and the inclination angle at the time of arrangement.
The formation of a triangular frame by combining these will be described.

First, description will be made of five types depending on the difference in length and inclination.
In the polygon formed by joining the triangular panels 1 to each other, a frame material forming a joining surface for five lines connecting five vertices from the center point of the pentagon and six line segments connecting six vertices from the center point of the hexagon There is a frame material that forms a joint surface. In the pentagon, there is a frame material that forms five sides of a pentagon. Further, the hexagonal body includes a frame material that forms a side that joins the hexagonal body among the six sides of the hexagonal shape, and a frame material that forms a side that joins the pentagonal body among the sides of the hexagonal body.

In addition, the joining of the frame members 2 is fastened by bolts and nuts. Although not shown in FIG. 1, holes for inserting bolts are formed in the frame material 2 at predetermined locations on the surface constituting the frame side surface of the triangular panel 1. Since a hole is formed in any frame material at the joint portion where the side surfaces of the frame body are abutted, fastening with bolts and nuts is possible.

Next, a description will be given of a frame constituted by a combination of five types of frame materials.
For example, there is an isosceles triangular frame composed of one first frame member 2a constituting a base that is a different side and two second frame members 2b constituting two equal sides. When a polygonal body is formed by the isosceles triangle, the second frame members 2b are joined together, and the first frame member 2a constitutes a side of the polygonal body.
In addition, there is an isosceles triangular frame composed of one fourth frame member 2d constituting a base which is a different side and two third frame members 2c constituting two equal sides. When a polygonal body including the isosceles triangle is formed, the sides of the polygonal body become the fourth frame member 2d that forms a base of a different side in the isosceles triangle shape.
Furthermore, there is an isosceles triangular frame body composed of one fifth frame member 2e forming a base that is a different side and two third frame members 2c forming two equal sides. When a polygonal body partially including the isosceles triangle is formed, the side of the polygonal body becomes the fifth frame member 2e that forms the base of one side different in the isosceles triangular shape.

Next, the construction method of the dome-shaped building using the polygon formed by the triangular panel 1 will be described.
The polygonal body will be described with reference to the description that the plural types of triangular panels 1 are formed based on the difference in the length of the frame member 2 and the difference in the inclined angle.

First, the types of the triangular panel 1 will be described.
The first triangular panel has an isosceles triangular shape, and the bases of different one sides are constituted by the first frame member 2a and the two equal sides are constituted by the second frame member 2b. In the second triangular panel, the bottoms of different sides are constituted by the fourth frame member 2d, and the two equal sides are constituted by the third frame member 2c. In the third triangular panel, the bottoms of different sides are constituted by the fifth frame member e, and the two equal sides are constituted by the third frame member 2c.

Next, a polygon formed by several types of triangular panels 1 will be described.
The pentagon is formed using only the first triangular panel. That is, a pentagon having the first frame member 2a as a side is formed.
In the construction of the dome-shaped building, as will be described later with reference to FIG. 7, in the dome structure according to the present invention, the pentagonal body has a structure that always contacts only the hexagonal body.

The hexagonal body has a configuration in which the second triangular panel and the third triangular panel are alternately arranged. That is, the hexagonal side has a shape in which the fourth frame member 2d and the fifth frame member 2e appear alternately.
Further, as illustrated in FIG. 7, the hexagonal body has a structure in contact with the pentagonal body and both polygonal bodies of the hexagonal bodies.

Next, a method for constructing a dome-shaped building will be described.
As a procedure for assembling the dome, first, the foundation work and the waist wall are placed by the conventional method, the foundation is installed and fixed, and the wall of the building is made. At this stage, the dome structure is structured so that no additional external force is exerted.
Further, as shown in FIG. 7A, the triangular panel 1 is grounded by a pentagonal body that forms a pentagonal shape that is connected to a bolt that is a fastening means by a dowel joint. Five sets of these pentagons are supported from the back on an assembly base.
And as shown in FIG.7 (b), five sets of hexagons which form a hexagon are assembled | attached to the said pentagon. Finally, as shown in FIG. 7C, the pentagonal body at the top of the dome is assembled to the hexagonal body to complete.

As described above, the triangular panel 1 having the structure according to the present invention makes it easy to construct a dome-shaped building.

Moreover, the structural member of the triangular panel 1 is a metal member, and by using a fire-resistant member, it becomes a structure excellent in fire resistance and corrosion resistance compared with the conventional wooden triangular panel.
Moreover, the frame material 2 which comprises the frame of the triangular panel 1 may be aluminum, and there exists an effect which can reduce building material cost.
