Improved scaffold

Abstract

The invention discloses an improved scaffold. Mainly, a bracket structure is formed by upright tubes, cross bars, diagonal members, scaffold floors and connecting mechanisms; the connecting mechanisms comprise U-shaped clamping parts, inserted pin parts, C-shaped clamping parts, T-shaped clamping parts and sleeves; each inserted pin part is of a flat and long shaped sickle structure formed by a straight big section and an arc small section; each straight big section is a structure of which one end is gradually necked down; each arc small section is supported at the corresponding necked end of the corresponding straight big section; the cross bars and the upright tubes are matched by the C-shaped clamping parts and the U-shaped clamping parts and are in stable joint connection by the self-locking of the inserted pin parts; the diagonal members and the upright tubes are matched by the T-shaped clamping parts and the U-shaped clamping parts and are subjected to stable joint locking by the matching of the inserted pin parts and T-shaped bayonets; the sleeves are fixedly connected to one end parts of the upright tubes; the inner diameters of the sleeves are matched with the outer diameters of the upright tubes; and each two upright tubes are stably connected up and down in a sleeve insertion mode. Compared with the prior art, according to the scheme, a stable and reliable scaffold with excellent comprehensive performances is formed.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to an improved scaffold. Background technique [0002] Scaffolding is an indispensable structural tool in building construction. Usually, scaffolding mainly includes bases, vertical rods, horizontal rods, diagonal rods and scaffolding boards. Among them, vertical rods are vertical rod structures that mainly bear construction and other loads. The cross bar includes a large cross bar arranged longitudinally along the scaffold and a small cross bar arranged transversely along the scaffold. Rods, cross bars, and oblique rods constitute the scaffolding bracket, and the scaffolding boards are laid between the layers of the scaffolding as a standing support surface and a platform for displaying tools and materials. The overall stability of the scaffolding bracket is related to the connection performance between the various components. The connection includes the connection between th...

Problems solved by technology

[0003] For example, a kind of scaffolding with steel pipe fasteners is more commonly used at present. The nodes are connected by steel pipe fasteners. Although it is more economical and more flexible to erect, it has the disadvantages that the fasteners are easy to lose, the node fasteners transmit load eccentrically, and the holding force depends on Manpower, difficult to control, prone to slippage, the connection quality of the fastener nodes is significantly affected by the quality of the fastener itself and manual operation, slow installation speed, etc.

For example, in the existing An Degu scaffold, the joints are connected by bolts and locked. It does not have the defects described in the steel pipe fastener scaffolding, and it is light and convenient, easy to assemble and disassemble, but the self-locking performance of the bolts is poor, which seriously affects the entire system. The stability of scaffolding

However, the existing scaffold boards widely use bamboo string boards, which are generally in the shape of long strips and arranged along the large horizontal bars of the scaffold. This structure has certain difficulties in transferring and moving, and its lateral sealing is not tight and the surface is not smooth. , the workers are not stable in walking and are prone to fall; moreover, when the bamboo string piece scaffolding board is installed, it is generally fixed on the scaffolding with iron wire, which has poor stability, is flammable and not fireproof, and has certain potential safety hazards, and the weight of the single block itself is very small. Large, and the bamboo slices have strong water absorption, which invisibly increases the burden on the scaffolding in rainy days

[0004] Therefore, the existing scaffolding lacks a structural design with excellent comprehensive performance. In view of this, the inventor has conducted in-depth research on the problems existing in the existing scaffolding, and this case arises from this
