A special-shaped pole

Abstract

The present invention discloses a special-shaped upright pole, which relates to the technical field of scaffolding, and includes a load-bearing square steel, a cast steel joint and an anti-torsion component. The load-bearing square steel is bolted up and down, and the cast steel joint is fixedly connected to the side end of the load-bearing square steel. A slot is provided at the side end of the cast steel joint, and a pin is inserted on the cast steel joint. A rivet is provided on the pin below the cast steel joint. The present invention installs an anti-torsion component at the side end of the load-bearing square steel, and cooperates with the cast steel joint with a slot. When occasional cracking and disconnection occur, the twisted load-bearing square steel drives the cast steel joint at the side end to rotate within the range of the concave guide rail on the transition disc until the side end of the cast steel joint abuts against the corresponding convex position, thereby blocking the continued twisting trend of the load-bearing square steel, ensuring the structural stability of the scaffolding, and avoiding the safety hazards caused by chain distortion.

Description

Technical Field

[0001] The invention relates to the technical field of scaffolding, and in particular to a special-shaped vertical pole. Background Art

[0002] Scaffolding is a temporary construction tool set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly for construction workers to work up and down or for the maintenance of the peripheral safety net and the installation of components at high altitudes. Its main structure includes horizontal and vertical horizontal and diagonal poles and vertical poles as well as scaffolding boards.

[0003] For the load-bearing vertical poles that play a major role, most of them use O-shaped cross-section beams. After long-term disassembly and assembly, cracks may occur at the stress concentration points where they are connected. Although occasional cracking and disconnection do not affect the horizontal and vertical structural strength of the overall frame, there is a tendency of torsional stress at this point, and the torsional strength requirements for the overall frame are relatively high. Once chain distortion occurs, it will bring great safety hazards to production. Summary of the invention

A slot is provided at the side end of the cast steel joint, and a pin is inserted on the cast steel joint. A rivet is provided on the pin below the cast steel joint. The anti-torsion component is installed on the side end of the load-bearing square steel through a connecting pipe, and is used to enhance the connection strength of the scaffolding while increasing the anti-torsion strength.

[0006] Preferably, the anti-torsion component includes a load-bearing upright and a transition disc, the side end of the load-bearing upright is fixedly connected to the connecting pipe, a connecting hole is provided on the load-bearing upright, and the internal thread of the load-bearing upright is provided with reinforcing ribs, the transition disc is fixedly set on the load-bearing upright, a fan-shaped concave guide rail is provided on the side end of the transition disc, a mounting hole and a buffer hole are provided on the concave guide rail, a twist-off section is provided between the mounting hole and the buffer hole, the concave guide rail is placed in a slot, and the pin is inserted in the mounting hole.

[0008] Preferably, the projection of the transition disc in the horizontal direction covers the slot.

[0009] Preferably, the buffer holes are disposed on both sides of the mounting hole.

[0010] The advantages of the present invention are: by installing an anti-torsion component on the side end of the load-bearing square steel, in conjunction with a cast steel joint with a slot, when an occasional crack or disconnection occurs, the twisted load-bearing square steel drives the cast steel joint at the side end to rotate within the range of the concave guide rail on the transition disc until the side end of the cast steel joint abuts against the corresponding raised position, thereby blocking the continued twisting trend of the load-bearing square steel, ensuring the structural stability of the scaffolding, and avoiding the safety hazards caused by chain distortion.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 4 As shown, a special-shaped vertical pole includes a load-bearing square steel 1, a cast steel joint 2 and an anti-torsion component 3. The load-bearing square steel 1 is bolted up and down, and the cast steel joint 2 is fixedly connected to the side end of the load-bearing square steel 1. A slot 4 is opened at the side end of the cast steel joint 2, and a pin 5 is inserted on the cast steel joint 2. A rivet 6 is arranged on the pin 5 below the cast steel joint 2. The anti-torsion component 3 is installed on the side end of the load-bearing square steel 1 through a connecting pipe 7, and is used to enhance the connection strength of the scaffolding while increasing the anti-torsion strength.

[0018] In this embodiment, the anti-torsion component 3 includes a load-bearing upright rod 31 and a transition disc 32, the side end of the load-bearing upright rod 31 is fixedly connected to the connecting pipe 7, a connecting hole 33 is provided on the load-bearing upright rod 31, and a reinforcing rib 34 is provided on the internal thread of the load-bearing upright rod 31. The transition disc 32 is fixedly set on the load-bearing upright rod 31, and a fan-shaped concave guide rail 35 is provided on the side end of the transition disc 32. The concave guide rail 35 is provided with a mounting hole 36 and a buffer hole 37, and a twist-off section 38 is provided between the mounting hole 36 and the buffer hole 37. The concave guide rail 35 is placed in the slot 4, and the pin 5 is inserted in the mounting hole 36.

[0019] It should be noted that the load-bearing square steel 1 and the load-bearing vertical rod 31 are both made of steel or aluminum alloy, the reinforcing rib 34 is made of steel, and a weakened structural opening is provided on the torsion-off section 38, so that the load-bearing square steel 1 breaks and the torsion-off section 38 breaks synchronously after the torsion-off section 38 breaks.

[0020] In this embodiment, the connecting pipe 7 and the cast steel joint 2 are respectively placed at the upper and lower parts of the load-bearing square steel 1 , so as to facilitate the rapid alignment of adjacent load-bearing square steels 1 and load-bearing vertical poles 31 .

[0021] In this embodiment, the projection of the transition disc 32 in the horizontal direction covers the slot 4, and the buffer holes 37 are placed on both sides of the mounting hole 36, so that after the load-bearing square steel 1 is broken and dislocated, the cast steel joint 2 can accurately abut against the end protruding position of the concave guide rail 35 on the corresponding transition disc 32 within the range of the buffer hole 37 on one side of the dislocation torsional trend, thereby blocking the continuation of the trend torsional.

[0022] Working process and principle: During use, the present invention installs the load-bearing square steel 1 one by one through port alignment, and the lower port of the torsion-resistant assembly 3 installed on the upper part thereof automatically aligns with the upper port of the torsion-resistant assembly 3 on the next group of special-shaped uprights, and the internal reinforcing ribs 34 are rotated to complete the fixed connection of the two connected load-bearing uprights 31, and at the same time, the transition disc 32 of the next group is aligned to the slot 4 on the previous group of cast steel joints 2, and the pin 5 is inserted into the cast steel joint 2 and the installation hole 36 and then fastened and assembled by the rivet 6, so that the installation of the two connected groups of special-shaped uprights is completed, and the installation of the scaffolding is completed in cooperation with the horizontal and oblique rods and the scaffolding board;

[0023] When the scaffold is in use and fracture and dislocation occur at the joint, the connection between the connecting pipe 7 and the torsion-resistant component 3 and the torsion-breaking joint 38 are fractured at the same time, and the twisted load-bearing square steel 1 drives the cast steel joint 2 at the side end to rotate within the range of the concave guide rail 35 on the transition disc 32, until the side end of the cast steel joint 2 abuts against the corresponding raised position, thereby blocking the load-bearing square steel 1 from continuing to twist. Under the premise of not affecting the structural strength of the overall frame in the horizontal and vertical directions, it is only necessary to disassemble and replace the special-shaped vertical pole group that has fracture and dislocation.

[0024] Based on the above, the present invention installs an anti-torsion component 3 on the side end of the load-bearing square steel 1, which cooperates with the cast steel joint 2 with a slot 4. When an occasional crack or disconnection occurs, the twisted load-bearing square steel 1 drives the cast steel joint 2 at the side end to rotate within the range of the concave guide rail 35 on the transition disc 32 until the side end of the cast steel joint 2 abuts against the corresponding raised position, thereby blocking the continued twisting trend of the load-bearing square steel 1, ensuring the structural stability of the scaffolding, and avoiding the safety hazards caused by chain distortion.

[0025] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
