An integral scaffolding node

Abstract

The invention provides an integral scaffold joint used for connecting a horizontal rod onto a vertical rod of a scaffold. The integral scaffold joint comprises a sleeve and two fastener joints, and the inner diameter of the sleeve is matched with the outer diameter of the vertical rod of the scaffold; the two fastener joints are fixed to the upper and lower portions of the sleeve respectively, each fastener joint comprises two fasteners, one fastener joint is used for connection with a transverse horizontal rod, and the other fastener joint is used for connection with a longitudinal horizontal rod. Each fastener comprises a fixing block, a large fastening ring, a small fastening ring, a lock piece, a lock chain, a wedge and a lock catch, each fixing block is fixedly connected with the sleeve, and each large fastening ring and each small fastening ring are connected with the corresponding fixing block through hinge pins respectively; each lock piece is fixed to a free end of the corresponding large fastening ring and connected with the corresponding lock chain through a shaft, and each lock chain is connected with the corresponding wedge through a shaft on the corresponding wedge; each lock catch is fixed to a free end of the corresponding small fastening ring, and each wedge is used for being fastened onto the corresponding lock catch. The integral scaffold joint has the advantages of quickness in mounting, simple structure and convenience in use.

Description

Technical field [0001] The invention relates to the field of scaffolding, in particular to an improved scaffolding node, which can be used for lap jointing of scaffolding in construction. Background technique [0002] Scaffolding refers to various supports erected on the construction site to provide workers with an operating platform and solve vertical and horizontal transportation. At present, the common scaffolds include fastener type steel pipe scaffolding, bowl buckle type steel pipe scaffolding, socket type steel pipe scaffolding, portal type scaffolding, etc. Among them, the fastener type steel pipe scaffold is the most common, but the following problems occur in the application process: [0003] (1) The traditional fastener type scaffold connects the horizontal rod and the vertical rod through two fasteners on a node, and transmits force through the fasteners, but the sliding stiffness and bending stiffness of the fasteners are weak, which greatly reduces the The be...

AI Technical Summary

Problems solved by technology

[0003] (1) The traditional fastener-type scaffold connects the horizontal rod to the vertical rod through two fasteners on a node, and transmits force through the fasteners, but the anti-sliding stiffness and bending stiffness of the fasteners are weak, which greatly reduces the Increased the bearing capacity of fastener scaffolding;

[0004] (2) Traditional fastener-type steel pipe scaffolding is usually equipped with one vertical and horizontal stress-bearing horizontal rod. Due to the fixed steel pipe specifications of the scaffold, the bending strength of the stressed horizontal rod is insufficient, making it difficult for fastener-type steel pipe scaffolding to be applied to heavy loads;

[0005] (3) Sometimes in order to improve the bending strength of the stressed horizontal bar on the top floor, when it is necessary to connect a vertical bar with multiple stressed horizontal bars, multiple fasteners are required, and the connection structure is complex and the connection effect is poor, resulting in the same The force-bearing horizontal rods in the direction are not at the same horizontal height, so that the load on the operating platform cannot be uniformly transmitted to the horizontal rods, which reduces the vertical stiffness of the scaffold and affects the construction accuracy and construction safety.
