Description

The present invention relates to simple structures such as platforms for expositions and glamping, temporary work stages such as temporary scaffolding for construction, temporary promenades, wooden decks of buildings, and other various stages, in which the stage frame has a truss structure. .

A truss structure is a structural type in which members are connected to each other in a triangular shape, and both ends of the members are pin-jointed to form a triangular shape, so even if external force is applied, only axial force is generated.

For example, if a force is applied to a quadrilateral, the quadrilateral will bend due to the force, but on the other hand, a triangle will not "bend" but will undergo deformation such as "shrinking" or "stretching" in response to the force. A bending moment acts on a member that undergoes the deformation of ``bending'', but only axial force acts on the deformation of ``shrinking or elongating''.

Even if the members are of the same size, the latter is overwhelmingly more advantageous when it comes to a member to which a bending moment acts and a member to which only axial force acts. In other words, an efficient cross section can be selected for a member on which only axial force is applied.

In this way, the advantages of the truss structure are shown below.
・Only axial force acts between members.
-Thus, it is possible to construct structures using thin members.
・Buildings can be created using light and thin members, and are attractive from a design standpoint.
This can be mentioned.

On the other hand, the pedestal for the stage is usually formed of pillars or pillars and beams, and there is no one that uses a truss structure for this.

A disadvantage of truss structures is that construction is cumbersome. A truss structure requires members such as an upper chord member, a lower chord member, a bundle member, and a diagonal member, and where the members intersect, the joints tend to become complicated.

Furthermore, when constructing a stage frame with a truss structure, there has been no concept of forming it in modules or cubes.

Purpose of the Invention It is possible to solve the disadvantages of the above-mentioned conventional examples, and to obtain a novel stage frame that is formed with a truss structure without pillars or beams.Furthermore, by using modules, parts can be procured in factory production. The purpose of the present invention is to provide a truss-structured stage that can be constructed by combining only modules without using members other than modules as connecting members, improves prefabrication, and allows easy and quick construction.

To achieve the above object, the present invention first constructs a stage pedestal by combining tetra modules in which the ridgeline portion of a regular tetrahedron is formed by a frame having an elongated joint surface, and a floor plate is laid on the top surface of the stage pedestal. ,Secondly, the tetra module forms a truss structure, in which the ridgeline part of a regular tetrahedron is formed by a frame with an elongated joint surface, the four vertices are equilateral triangular planes or regular hexagonal planes, and the tetrahedron is formed into a cubic cube. The frame is inscribed in the surface. Thirdly, the lower side of the stage mount is sloped to match the inclined surface on which it is installed. Fourthly, the frame of the Tetra module can be assembled in a manner that can be disassembled. Fifthly, the Tetra module The gist of this is to assemble modules so that they can be separated from each other via joint blocks.

According to the present invention as set forth in claim 1, it is possible to realize an unprecedented and novel stage in which the entire stage frame is formed with a truss structure.

The tetra module forms a truss structure, and the ridgeline portion of the regular tetrahedron is formed by a frame having an elongated joint surface. Therefore, the tetra modules can be combined by joining the elongated joint surfaces of the frames.

Furthermore, when combining tetra modules, the frames that form the ridgeline parts of the regular tetrahedron overlap each other, making them double, increasing strength, and if this is the diagonal part of the truss structure, the truss structure itself is strong. becomes.

In addition, the four vertices of the tetra module are equilateral triangular planes or regular hexagonal planes, so when the tetra modules are combined, these apex parts collide to form a three-dimensional space, or a space in which a joining block can be inserted. A stable joint is obtained as a truss structure.

In addition, if the four vertices are regular triangular planes, you can expect the strength of the tetra module itself, and if the four vertices are regular hexagonal planes, the frame will be assembled with one side of the regular hexagon in between and the remaining three sides as connecting sides. This makes it easy to connect the frames that form the sides.

In addition, since it is based on tetra modules, it is possible to construct a truss structure by combining only modules without using connecting members other than modules, and assembly can be performed easily and quickly with less man-hours, and prefabricated. will improve.

Furthermore, when assembling modules, the frames that form the ridge lines of the regular tetrahedron overlap each other, making them double, increasing strength, and if this is the diagonal part of a truss structure, the truss structure itself is strong. becomes.

Additionally, it is possible to construct a temporary stage that matches the terrain while preserving it without altering it.

According to the second aspect of the present invention, by treating the tiger module as a cubic cube, it is possible to assemble a so-called block product, and furthermore, by combining a plurality of cubes to form a large cube, the number of construction man-hours can be reduced. can be achieved.

According to the present invention as set forth in claim 3, when assembling the stage pedestal with tetra modules, the lower side of the pedestal has an inclination by arranging the tips of the tetra modules in steps, so that the lower side of the pedestal has an inclination. You can build a stage stand.

According to the present invention as set forth in claim 4, by assembling the frame so that the tetra module can be disassembled, the tetra module itself can be easily assembled on site by joining the members, and it is also easy to assemble during relocation etc. The stage can also be dismantled easily.

According to the present invention as set forth in claim 5, since the tetra modules are separably assembled via the joint block, even if the tetra modules are manufactured in a factory, the truss structure using the tetra modules can be assembled and dismantled on site. can be done easily.

As described above, the truss structure stage of the present invention has no pillars or beams and has a truss structure, which is a novel stage frame.Also, by using modules, parts can be procured during factory production. This makes it possible to construct a structure by combining only modules without using members other than modules as connecting members, improving prefabrication and making construction easier and faster.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of a stage having a truss structure according to the present invention, which is composed of a stage pedestal 10 and a floor plate 11 laid thereon.

Although the illustrated example is a stage built on a slope, the stage of the present invention can be anything that has a floor plate on a pedestal, such as a wooden deck, a simple structure, a monument, etc. Various structures such as objects, temporary stages, etc. can be targeted.

The stage pedestal 10 of the truss-structured stage of the present invention is constructed by combining tetramodules 1 each having a frame 3 having a slender joint surface at the ridgeline portion of a regular tetrahedron, and the tetramodule 1 will be explained first. As shown in FIGS. 2 and 3, the tetra module 1 has a frame 3 having a slender joint surface 2 at the ridgeline portion of a regular tetrahedron α, and four vertices 4 made of regular triangular or regular hexagonal flat plates. 2 shows a case where the apex 4 is a regular triangle, and FIG. 3 shows a case where the apex 4 is a regular hexagon.

A regular tetrahedron has four vertices and six sides, and the angle between the lines connecting the center of the regular tetrahedron and the vertices of the regular tetrahedron is 109.5 degrees.

The elongated joint surface 2 of the frame 3 is a surface obtained by cutting out the sides (ridge lines) of a regular tetrahedron, and the angle formed by the plane is a slope in the width direction of the elongated joint surface 2 with respect to the center of the regular tetrahedron. It's something that doesn't exist. Further, the width of the elongated joint surface 2 depends on the extent of the scraping described above, but is not particularly limited.

The tetra module 1 is a regular tetrahedron, but more precisely, it is assumed to be a regular tetrahedron, and the ridgeline portion of the regular tetrahedron is formed by a frame 3 having an elongated joint surface 2. The ends were connected with flat plates and assembled into a regular tetrahedral frame. Note that all frames 3 have the same length.

In the tetra module 1, the frames 3 are connected to each other by equilateral triangular flat plates 5 or regular hexagonal flat plates 6, so that the four vertices are equilateral triangular planes or regular hexagonal planes. FIG. 10 shows a development in the case of connection using a regular hexagonal flat plate 6.

The tetra module 1 may be made of steel, cast iron, SUS, aluminum, wood, resin, etc., but metal or wood is preferable for the stage frame.

Further, the manufacturing method of the tetra module 1 includes welding, bolting, bending, casting, etc. The regular triangular flat plate 5 or the regular hexagonal flat plate 6 may be formed as a joint member of the frame 3 with a joint piece.

The tetra module 1 can be assembled with the frame 3 disassembled. If the frame 3 is made of wood and the tetra module 1 is made of wood, a dowel joint as shown in FIG. 14 or a mortise-tenon joint as shown in FIG. 15 can be used.

In the case of dowel joints, the regular hexagonal flat plate 6 is a thick block body, with dowels 12 protruding from the ends of the frame 3, which are inserted into dowel holes 13 provided in the regular hexagonal flat plate 6. .

In the case of a mortise and tenon joint, the regular hexagonal flat plate 6 is a thick block body with a tenon 14 projecting from the end of the frame 3, which is inserted into a mortise groove 15 provided in the regular hexagonal flat plate 6.

When the frame 3 of the tetra module 1 is made of metal such as steel, cast iron, SUS, or aluminum, the equilateral triangular or hexagonal flat plate 6 is configured as a joint member having a joint piece 6a, as shown in FIG. By fastening with bolts and nuts 16, the tetra module 1 can be assembled so that the frame 3 can be disassembled. In the illustrated example, the frame 3 is formed of a square tube or an angle material, and the joint piece 6a is inserted into the end of the frame 3 and fixed.

As shown in FIG. 4, the tetra module 1 can be regarded as a cubic cube 12, in which the ridgeline portion of a regular tetrahedron is formed by a frame 3 having an elongated joint surface, and the four vertices are formed by an equilateral triangular plane 5 or a regular hexagonal plane. 6, the frame 3 is inscribed in the surface of the cube.

In this way, we decided to create cubic cubes using modules that would serve as unit structures, and to connect the cubes to each other. A module can be compared to one of the "structural units" that form a crystal structure, and by multiplying it, a truss structure can be formed.

In order to construct a module that can be used as a cube and to combine this module to construct a three-dimensional truss structure, the frame 3 which becomes the ridgeline part of the polyhedron is connected to the elongated joint surface 2 of the member having the elongated joint surface 2. This is done by joining.

As a result, it has become possible to construct a three-dimensional truss structure by combining only modules without using components other than modules as connecting members, improving prefabrication and making assembly easier and faster with fewer man-hours. .

Modules can be multiplied by connecting them to each other, but since they are connected surface to surface, the direction is determined and it is possible to assemble them stably.

Furthermore, when assembling the modules, the frames 3, which are the ridgeline parts of the polyhedrons, overlap each other and become double, increasing the strength.If this is the diagonal part of the three-dimensional truss structure, the three-dimensional truss structure itself will be strong. Become something.

In addition, each module is constructed by joining the frames serving as the ridgeline portions at their elongated joint surfaces, so that a multilayer stable truss structure can be assembled by stacking the modules not only in the lateral direction but also in the vertical direction.

Furthermore, since a stable truss structure with variable shape can be constructed by simply connecting modules, it is possible to easily respond to changes in specifications and space changes after construction.

11 and 12 show an even larger cube 12 constructed by combining four cubes 13 of the tetra module 1. The tetra module 1 has frames 3 having elongated joint surfaces 2 lined up, and the elongated joint surfaces 2 By facing outward, the cube 12 is configured as a flat block body consisting of an upper surface X, a lower surface Y, and a side surface Z.

Next, the formation of the stage frame 10 of a truss-structured stage using the tetra module 1 will be described.

The tetra modules 1 are assembled by joining each other as unit modules to form a truss structure, and as shown in FIG. 13, frames 3 having elongated joint surfaces 2 are joined by overlapping each other at the elongated joining surfaces 2.

In addition, in order to overlap frames 3 having elongated joint surfaces 2 and fix them using the parts of the frames 3, it is possible to connect them by fastening with bolts and nuts 16 as shown in FIGS. 17 and 18. It is.

Moreover, the tetra modules 1 can also be assembled so as to be separable from each other. 17 and 18 show an example of this, in which a joint block 17 having a regular hexagonal plane that matches the regular hexagonal plane 6 is interposed in a space where the regular hexagonal planes 6 of the tetra module 1 are assembled. A rectangular flat surface 6 was fixed to this with bolts 18. FIG. 17 shows a case where the joint block 17 is spherical, and FIG. 18 shows a case where it is hemispherical.

When forming the stage frame 10 of a truss-structured stage using the tetra module 1, it can be constructed by arranging the cubes 12 side by side or stacking them.

Figure 1 shows a case where the stage is installed on an inclined surface, and the tetra module 1 can be assembled from the bottom with a step, so that the lower side of the stage pedestal 10 can be sloped to match the slope on which it is installed. Ta. Note that it is also possible to use one without such an inclination.

The stage is completed by laying a floor plate 11 on the upper surface of the stage frame 10, and a laying iron plate is laid on the floor plate 11 and fixed with commercially available connecting fittings. In addition, various materials such as lining boards, wooden pallets, etc. can be used. The floorboard 11 is arranged on the tetramodule 1 constituting the stage frame 10 and fixed with bolts and nuts or other means.

The stage of the present invention can be easily installed and dismantled if the tetra modules 1 constituting the stage mount 10 are assembled so that the frame can be disassembled, or if the tetra modules are assembled separably from each other via joint blocks. , also suitable for relocation.

For the joint block 17, a half-split spherical part of a truncated plane consisting of 8 hexagonal faces and 6 square faces is used, but as shown in FIG. It's fine to use one.

By using the half-split type, the floor surface (floorboard installation surface) can be smoothed as shown in FIG. 19, and the stage end can be shaped by spanning the beam 19 through the joint block 17. be able to.

In addition, when installing the stage stand 10 of the stage on a slope as shown in FIG. 1, a stake 20 with a head pedestal 21 as shown in FIG. 24 is installed (see FIG. 22), and The stage pedestal 10 is assembled thereon as shown in FIG.

The pedestal 21 plays a role similar to that of the joint block 17.

In recent years, luxury camping called glamping has become popular, and the surface on which the dome tent is set up requires a floor surface called a platform, which is currently constructed using the traditional wooden floor construction method.

In glamping, there is a need for a more novel and attractive way to appeal, and the truss structure stage of the present invention makes it easy to construct a multi-tiered or multi-layered platform for such glamping, and improves visibility. This makes it possible to create an excellent glamping layout plan.

By creating a highly transparent platform (stage) with a truss structure, it is possible to plan to maximize the surrounding scenery. Depending on how you display it, it feels like you're floating in the air. By minimizing on-site land preparation work, it is possible to plan glamping projects while minimizing the destruction of nature.
