Example Embodiment

[0037] Example 1: A connection assembly of closed-loop pipe and plate, such as Figure 1-2 , Including a cylindrical connecting column 1, one end of the connecting column 1 is provided with a rectangular movable groove 11, a rotating shaft 2 is fixed in the movable groove 11, and a rectangular force block 3 is sleeved on the rotating shaft 2 to receive the force. The center of the block 3 deviates from the center of the shaft 2. As the force-bearing block 3 has a uniform texture, its center of gravity and center are at the same end of the shaft 2; when the force-bearing block 3 and the connecting column 1 are on the same straight line, the center of gravity of the force-bearing block 3 is close The bottom of the movable groove 11. The length of the force receiving block 3 is greater than the diameter of the connecting column 1, so that after the force is rotated, the movable grooves 11 at both ends can abut the inner wall of the connecting hole 61 on the closed loop pipe 6; the...

Example Embodiment

[0043] Embodiment 2: A connection assembly of closed-loop pipe and plate, such as Figure 5 The difference from Embodiment 1 is that a guide part 34 is fixed on the side of the force receiving block 3 close to the cut 32. The cross section of the guide part 34 is a right-angled triangle, and the slope of the guide part 34 and the slope of the cut 32 face the same direction.

[0044] Such as Figure 4 , A blocking member 13 is fixed on the inner side wall of the movable groove 11 near the bottom of the groove. The blocking member 13 is a cylindrical protrusion that abuts the side wall adjacent to the force receiving surface 31 in the force receiving block 3; the blocking member 13 is formed by It is made of rubber and is glued to the side wall of the movable groove 11. When the force receiving block 3 abuts against the blocking piece 13, the blocking piece 13 is compressed, and the force receiving block 3 cannot be deflected under the condition of only gravity. When the force recei...

Example Embodiment

[0049] Embodiment 3: A connection assembly of a closed-loop pipe fitting and a plate. The difference from Embodiment 1 lies in: Figure 7 , A limit post 14 is fixed in the movable groove 11, and when the force receiving block 3 and the connecting post 1 are on the same straight line, the limit post 14 abuts the force receiving surface 31.

[0050] When inserting the installation hole 71, hold the connecting column 1, the force receiving surface 31 of the force receiving block 3 faces downwards, and when the force receiving block 3 extends into the closed loop pipe fitting 6, rotate 180 degrees so that the force receiving surface 31 of the force receiving block 3 Upward, at this time, the force receiving block 3 rotates inside the closed loop pipe 6 due to the eccentricity of gravity. Pull back the connecting column 1 so that the force-receiving surface 31 abuts against the inner wall of the connecting hole 61 of the closed-loop tube 6, sleeve the elastic washer 4 on the connecting...

Abstract

The invention provides a closed-loop pipe and plate connection assembly. The assembly comprises a connection column, a moving groove and a stressed part, wherein the moving groove is formed in one endof the connection column, the stressed part is rotationally connected in the moving groove and used for penetrating a connecting hole to enter a closed-loop pipe, the stressed part comprises a stressed surface used for abutting against the inner wall at the connection hole of the closed-loop pipe, and an external thread is formed in the connection column and connected with a nut. The connecting hole is formed in the closed-loop pipe, an installation hole is formed in a plate, the diameter of the connecting hole is equal to that of the installation hole, and the connecting hole is concentric with the installation hole; the diameter of the connection column is slightly smaller than the diameter of the connecting hole. The stressed part stretches into the closed-loop pipe, and the stressed part is driven to rotate through external force or self weight, so that the stressed surface abuts against the inner wall at the connecting hole of the closed-loop pipe; then the nut is rotated to makethe nut abut against the plate, and therefore, quick connection of the closed-loop pipe and the plate is achieved.

Description

technical field [0001] The invention relates to a building connection structure, in particular to a connection assembly of a closed-loop pipe and a plate. Background technique [0002] The main skeleton material of the light steel structure house is a light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology. After accurate calculation and the support and combination of auxiliary parts, it has a reasonable bearing capacity to replace the traditional house structure. . [0003] Due to the high cost and long construction period of traditional houses, light steel houses are becoming more and more popular. [0004] The beams and columns of light steel houses generally use non-closed-loop fittings such as I-shaped steel and C-shaped steel, and are similar to closed-loop pipe fittings such as square steel. Due to the narrow internal space of closed-loop pipe fittings, the connection holes on the side walls of closed-loop pipe fittings are basi...
