Problems solved by technology

[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 basically consistent with the diameter of bolts. , the cap of the nut or bolt cannot enter the connection hole, and the connection cannot be formed

Embodiment 1

[0037] Embodiment 1: A connection assembly of a closed-loop pipe fitting and a 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 bearing block 3 is rotated and socketed on the rotating shaft 2. The center of the block 3 deviates from the center of the rotating shaft 2, and because the texture of the stressed block 3 is uniform, its center of gravity and the center are at the same end of the rotating shaft 2; The groove bottom of movable groove 11. The length of the force-bearing block 3 is greater than the diameter of the connecting column 1, so that its two ends extend out of the movable groove 11 after being rotated under force, and can abut against the inner wall of the connecting hole 61 on the closed-loop pipe fitting 6; the height of the force-bearing block 3 is less than that of the con...

Embodiment 2

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

[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, and it resists the side wall adjacent to the force receiving surface 31 in the force receiving block 3; the blocking member 13 is formed by Made of rubber, and bonded to the side wall of the movable groove 11, when the force block 3 abuts on the block 13, the block 13 is compressed, and the force block 3 cannot be deflected under the condition of gravity alone through friction. When the force bearing block 3 and...

Embodiment 3

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

[0050] When inserting into the installation hole 71, hold the connecting column 1, the force-bearing surface 31 of the force-bearing block 3 faces downward, and when the force-bearing block 3 extends into the closed-loop pipe fitting 6, turn 180 degrees so that the force-bearing surface 31 of the force-bearing block 3 Upward, at this moment, the force-bearing block 3 rotates eccentrically in the closed-loop pipe 6 due to its own gravity. Pull back the connecting column 1 so that the force bearing surface 31 abuts against the inner wall of the connecting hole 61 of the closed-loop pipe fitting 6, put the elastic washe...

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...
