Description

The present invention relates to a joining apparatus that joins shaft members and joining base materials together for building construction, assembling machines and instruments, and the like.

Conventionally, in order to construct a structure such as a three-dimensional truss, there has been a joining device such as screw joining a shaft member to a sphere. (See Patent Documents 1, 3, and 4)

Japanese Patent Application Laid-Open No. 2002-37162 proposes a method of joining various shafts by joining shaft members to form a triangular pyramid unit frame, connecting the unit frames obliquely horizontally, vertically and so on to construct various buildings. (See Patent Document 6)

There has been a joining device that joins shaft members together by joining base materials, assembles a polygonal plane unit or a polyhedral unit, and joins the units together by joining the joining base materials.
(See Patent Document 2)

In Japanese Patent Laid-Open No. 2002-37162, it has been proposed that a shaft member having an arbitrary length is formed by expansion and contraction of a shaft tube tip member and joining of four types of shaft members having different lengths. (See Patent Document 6)

In order to construct a building structure using a log material, there has been a joining device for screwing a joining device having a bolt attached to the tip of the log material to a joining base material such as a mounting sphere. (See Patent Documents 5 and 7)

When joining a shaft member to a joining base material such as a sphere, conventionally, since the shaft member is directly screw-joined to the joining base material, the direction of the shaft member relative to the joining base material is constant. In addition, it is necessary to thread the joining base material, and since there are more types of joining devices, there is a difficulty in standardization.

FIG. 18 to FIG. 24 are examples of Japanese Patent Laid-Open No. 2002-371625. FIG. 18 is a perspective view of the artificial ground formed by connecting the triangular pyramid unit frames 3 obliquely and laterally. FIG. 19 is a plan view of an embodiment in which a house is built on an artificial ground constructed by connecting three triangular pyramid unit frames. FIG. 20 is a three-dimensional view thereof. FIG. 21 is a perspective view of a building constructed by connecting the triangular pyramid unit frames 3 vertically and horizontally and vertically. FIG. 22 shows a dome framework in which a triangular pyramid unit frame 80 ′ is connected in a circle and a floor set 85 ′ and a roof set 81 ′ are added. FIG. 23 shows a triangular pyramid unit frame 3 in which an inclined member (post) 2 and a truss beam 4 are combined. FIG. 29 shows a building constructed by joining it and the truss beam 4. Since the upper and lower ends of the inclined members 2, 77 ′, 79 ′ are hinge-joined, the height of the horizontal members 1, 76 ′ from the ground can be freely adjusted with the same joining device. See FIG. However, it is necessary to replace the joining device depending on the shape of the triangle formed by the horizontal member 1 or the shape of the unit frame. The large number of types of joining devices poses a difficulty in realizing material stock → assembly → disassembly → stock circulation.

An object of the present invention is to construct a triangular pyramid-shaped unit frame having an arbitrary shape by using a single type of joining device and a shaft member so that the shaft member can be bonded to the bonding substrate at an arbitrary angle.

When a frame is constructed using the joining apparatus of FIG. 23, a scaffold or a temporary mount is required. In addition, if there is tree planting at the bottom, it will fail to plant trees. It is desirable to assemble the unit frame on the ground suitable for assembling, and to bond them, that is, the bonding substrates.

There was also an attempt to join the joining base materials, but in the production and construction that the screw hole position and direction must be matched simultaneously at the contact point or a slightly separated position between the joining base materials such as spherical shapes. There was difficulty. In addition, when the joining base material is made into a sphere and a plurality of joining base materials are joined and joined together, there are problems in design and maintenance such as painting and cleaning.

Another object of the present invention is to facilitate joining by joining the bonding substrates to each other in terms of positional deviation and angle, and to integrally bond the bonding substrates in terms of design and maintenance. It is in.

The connecting device with bolts, anchor nuts, and sleeves attached to the tip of the shaft member requires precision because there is no device for adjusting the length of the shaft member, and the bolt and anchor nut are stored in the tip shaft tube. However, since it has the complexity of having a sleeve for bolt feeding, it cannot be said that it is suitable for joining small parts such as machine tools.

In Japanese Patent Application Laid-Open No. 2002-371625, a shaft tip member that is provided with a bolt hole at the tip and attached or integrally processed to a tip of a shaft tube with a hinge plate that is processed so as to be able to be hinge-joined with a joint base such as a joint metal A simple device that can be screwed to the tip of a shaft member made of an outer meridian tube and can adjust the length of the shaft member has been proposed. However, since the device for stopping the rotation of the tip member and fixing the shaft tip member to the shaft tube is missing, there is a possibility that the tip member may vibrate depending on the external force.

Another object of the present invention is to join the tip of the shaft member, which can be adjusted by screwing the shaft tip member to the tip of the shaft member, and fixing it after determining the required protrusion length and rotation angle. The purpose is to build a device and use it widely in buildings, machinery, etc. in accordance with the above purpose.

There has been a technique for constructing a building by attaching members such as bolts, anchor nuts, and sleeves to the end of the log material, and joining the log materials through joint hardware. This joining device requires precision because there is no device for adjusting the length of the shaft member, and has the complexity of housing a bolt and an anchor nut in the metal member at the tip and holding a bolt feed sleeve. For this reason, it is not envisaged to join small non-metallic parts such as lighting fixtures and everyday items.

Another object of the present invention is to create a joining device at the tip of a shaft member that can be adjusted in length by simply adding a device with a simple mechanism to the tip of a non-metallic shaft member such as wood or plastic. Is widely used for buildings, furniture, lighting fixtures, everyday items, etc. in accordance with the above purpose.

A bolt hole 11 is provided at the tip on the surface opposite to the spherical center of the joining base material 14 and a hinged bolt 13 processed so as to be able to be hinge-joined with the shaft member is screw-joined. The rotation angle is determined and fixed with the tightening nut 15. The end portions of the joining base material 14 are joined with the bolts 18 via the spheres 17.

The hole of the joining base material 14 through which the bolt 18 passes is made a larger hole than the bolt 18, and a partial spherical engraving is put on the tightening nut 19 side and the bolt head side, and the partial spherical shape is the same shape as the partial sphere on both sides of the bolt. The washer 20 is sandwiched.

The shaft tip member 25 is screwed to the tip of the shaft tube 28, and the shaft tip member 25 is clamped and fixed with a circular nut 26 having the same diameter as that of the shaft tube, with the required protruding length and rotation angle determined.

A bolt with a hinge is screwed to a joining base material, and this can be fixed at an arbitrary rotation angle with a tightening nut. Accordingly, the hinged shaft member from any direction and angle can be joined to the joining base material. Also, the hinged shaft members can be joined from any direction and angle.

The joining base material may be penetrated with a hinged bolt, and this may be fixed with a hinged nut or a tightening nut. Alternatively, the hinged wood screw may be screwed into a joining base material made of a non-metallic member such as wood or plastic and stopped at a necessary rotation angle.

By simply changing the number of hinge bolts and shaft members to be attached to the joining base material and joining them together, a shape and a framework that can be formed by a triangular shape such as a triangular shape, a triangular pyramid shape, etc. Can be built or built. Furthermore, if a rigid surface such as a plate material is added to a polygonal surface other than a triangular shape and the shape is maintained, an arbitrary shape and frame can be manufactured or constructed using the joining device and the shaft member. It is possible. It is possible to standardize the joining device according to the purpose of production or construction.

In the present invention, units such as a triangular pyramid unit frame are joined to each other. Therefore, the joining bases of the units are joined to each other by providing a wide width or by adjusting the lengths of the shaft member and the hinged bolt. It makes it easy by adjusting their angles and positions.

If the unit is a structural unit such as a triangular pyramid-shaped unit frame, Japanese Patent Laid-Open No. 2002-37162
As shown in FIG. 18 (parts of which are shown in FIGS. 18 to 24), it is easy to construct various structures by connecting the units two-dimensionally or three-dimensionally.

Since these buildings have truss structures, the cross section of the member can be minimized, and the weight of the member and resource saving can be achieved. Since the shaft member is joined by only one pin bolt, the assembly and disassembly of the member is easy, and the reuse of the member is easy.

Unlike conventional ball joints (shaft members are directly screwed to the spherical base material)
Since the structural units can be joined to each other, there is no need for a scaffold or a temporary mount, and it is easy to build a building in places where water and planting zones cannot enter.

The shaft tube of the shaft member and the hinged tip member are screwed together, and the protruding length of the tip member is set to the required length and fixed with a circular nut of the same diameter as the shaft tube, so the length of the shaft member can be adjusted In addition, it is possible to use a single shaft member by allowing manufacturing and construction errors and changing the length of the shaft member.

Since a non-metallic member such as wood or plastic can be used for the shaft member, the building can be constructed using a log material or the like. It can also be used for other structures such as furniture and lighting equipment.

From the above, it can be said that the construction method using the joining apparatus of the present invention is an extremely environmentally friendly construction method.

Compared to conventional ball joints and other joining devices, the details of the joints are simple details with a single pin bolt called a hinge joint, so it is also widely used for joining relatively small parts such as machines, instruments and furniture. Available.
