Description

Truss joint

This creation department relates to trusses, especially a kind of truss joint.

The truss structure is a widely used engineering structure. No matter in houses, bridges, electric towers or outdoor stages, the application of truss can be seen; the truss is generally composed of multiple straight rod elements. The joint is used for connection. One of the common joints is the six-sided joint; the six-sided joint is usually a cube with six joints, hence the name. The six-sided joint is used to connect multiple straights in a right-angle relationship. The pole element occupies a pivotal position in the truss structure.

As shown in FIG. 10, it is a common existing six-sided joint, which includes six joint blocks 90 welded to each other. The six joint blocks 90 are approximately square, and each joint block 90 includes a joint surface 901, and Four connecting pieces 91 located at the four corners of the connecting block 90; the connecting surface 901 of each connecting block 90 is perpendicular to the connecting surface 901 of the four adjacent connecting blocks 90; the connecting piece 91 The six connecting blocks 90 are provided with solder joints for welding each other, and the two connecting blocks 90 are additionally connected by a connecting plate 80. The connecting plate 80 is welded to the two connecting blocks 90 to strengthen the six The strength of the connection between the blocks 90.

However, the existing six-sided joint has the following disadvantages: as shown in FIG. 11, since the six joint blocks 90 of the existing six-sided joint are welded to each other, the joint faces 901 of the six joint blocks 90 cannot be aligned with each other, as shown in FIG. As shown in 12, when the existing six-sided joint is applied to a truss structure, a plurality of straight rod elements 70 are respectively joined to the joint faces 901 of the six blocks 90, and the cross-sectional area of each straight rod element 70 is equal to The joints 901 of the connecting blocks 90 have the same area. Because the joints 901 of the six connecting blocks 90 cannot be aligned with each other, the existing six-sided joints are connected to the plurality of straight rod elements 70, the truss structure is The overall shape is uneven. When the above truss structure is used in outdoor stage construction, when the curtain is hung, the curtain will be uneven due to the uneven overall shape of the truss structure, which affects the look and feel.

In order to solve the problem that the six joint blocks of the existing six-sided joint are welded to each other, the joint faces of the six joint blocks cannot be aligned with each other. The uneven shape of the truss structure is used for outdoor stage construction. When the curtain is hung, the curtain will be uneven due to the uneven overall shape of the truss structure, which affects the look and feel. The purpose of this creation is to provide A truss joint that can make the overall appearance of the truss structure flat and easy to disassemble and assemble.

In the truss joint, the first plane and the second plane of each joint block are rounded squares.

In the truss joint, each of the joint blocks includes a plurality of setting holes, each of the setting holes is a screw hole, and each of the setting holes penetrates the first plane of the joint block and the second plane of the joint block.

In the truss joint, each of the joint blocks includes a through hole located in the middle of the joint block and penetrates the first plane of the joint block and the second plane of the joint block.

In the truss joint, each of the joint blocks includes four perforations, each of which penetrates through the first plane of the joint block and the second plane of the joint block, and the four perforations are respectively adjacent to four corners of the joint block .

In the truss joint, a plurality of setting holes of each joint block surround the through hole of the joint block.

In the truss joint, a plurality of counterbores and a plurality of screw holes of each joint block are arranged in a staggered manner.

The effect of the technical means of this creation can be improved in that: in the truss joint of this creation, each of the joint blocks is in the shape of a quadrangular pyramid, and the circumferential surfaces of the at least five joint blocks abut against each other and are consolidated by screws to form a cubic shape. Space, the first planes of the at least five joint blocks are aligned with each other, and when the plurality of straight rod elements in the truss structure are respectively combined with the first planes of the at least five joint blocks, the overall shape of the truss structure is flat, and when used in an outdoor stage When the curtain is set up, it will not affect the smoothness of the curtain.
