Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aggregate having a rectangular cross section in the up-down direction (X-axis), the left-right direction (Y-axis) and the front-rear direction (Z-axis).
Such as a shaft), a triaxial clamp that intersects at right angles to each other, especially a triaxial that is suitable for assembling frames and shelves for storage protection of containers and equipment used in hospitals and various laboratories. For clamps.

[0002]

2. Description of the Related Art As a typical example of a so-called triaxial clamp for joining three aggregates extending in the X-axis, Y-axis and Z-axis directions at their intersections, a practically open type 63-
An example is a triple clamp as described in Japanese Patent No. 94255 or Japanese Utility Model Laid-Open No. 62-203346.

In this conventional triple clamp, a clamp for vertically holding a vertical pipe and a clamp for horizontally holding a horizontal pipe are connected to each other in an orthogonal state, and further orthogonal to the horizontal pipe. A clamp for gripping a horizontally arranged pipe is connected to the clamp of the vertical pipe at right angles, and a fastening means is provided at the opening of each clamp. The triaxial clamp having such a structure is mainly applied to an outdoor assembly made of a pipe material having an outer diameter of 25 mm or more, for example, an assembly scaffold at a construction site or a greenhouse cultivation house.

On the other hand, a pipe of an assembled structure formed by a thin pipe material having an outer diameter of 20 mm or less, such as a frame or a shelf for storage and protection of containers and equipment used in a hospital or various laboratories. A pair of cast clamps shaped like a three-blade propelling screw are preferably used for the connection of, and the screw-shaped clamps are fitted from the inside and outside of the intersection of the three axes, and the central part By tightening the screws, the intersections of the three pipe materials can be joined.

[0005]

However, the former clamp described above has the advantage that the three pipes are individually gripped and thus has a large bonding force, but the structure is complicated and the manufacturing cost is high. Further, since the shape of the clamp is large, the clamp protrudes at the joint portion, which is unreadable. Therefore, this type of clamp is generally used for an assembled scaffolding frame for construction as described above, and is not suitable as a clamp for a frame body used indoors.

On the other hand, the latter screw type clamp is convenient for an indoor assembly frame because of its simple structure and good appearance of the connecting portion. However, since the aggregate used for the frame and shelves is a pipe material with a circular cross section, and because it has a simple clamp structure, the pipe material can easily rotate in the circumferential direction even when fastened, and external force and vibration are further applied. It is easy to induce loosening of the joints, and if the discovery of looseness is delayed, there is always anxiety that it will cause a frame or shelf collapse accident.

The present invention has been made for the purpose of providing a triaxial clamping device which uses square members having a rectangular cross section as aggregates and which can easily and firmly connect the triaxial intersections of the rectangular members. is there.

A clamp device at a crossing portion of a rectangular aggregate having a cross section which is arranged in the vertical direction, the horizontal direction, and the front-rear direction and intersects with each other, and the clamp device is fitted to the aggregate in the vertical direction. The first member includes a first member, a second member that supports the aggregate in the left-right direction and the front-rear direction, and a third member that fixes the aggregate in the left-right direction and the front-rear direction supported by the second member. Is the outermost 3 of the aggregate
Of the second member having a fitting portion including a central surface portion that faces one surface and left and right side surface portions, and a front end that further extends forward from the lower portions of the left and right side surface portions and has an engaging portion at the end of the second member. A support portion and a support surface of an aggregate in the front-rear direction, which is formed by bending outward from the upper end of one side surface portion, are provided, and the second member has a U-shaped vertical cross section. A vertical wall that can be fitted to the opening side of the fitting portion of one member, a horizontal plane that supports the aggregate in the left-right direction, an upper end of the vertical wall that is bent parallel to the horizontal plane, and has a screw hole at the center position, and the horizontal direction. The mounting surface of the third member located on the upper surface side of the aggregate, and further provided on the lower surface side of the horizontal surface is a pressing means for fixing the first member to the aggregate in the vertical direction. The member has a screwing surface mounted on the mounting surface of the second member and an upper surface mounted on the mounting surface. A crown portion that is located above the mounting portion of the first member and that presses and clamps the front-rear direction aggregate that is located on the support surface from the upper surface side, and the left and right portions that are located above the horizontal surface of the second member. A triaxial clamping device for square aggregates, characterized in that a hanging tongue for pressing and fixing the aggregates in a predetermined direction is provided.
