Adjustable steel pipe scaffold

Abstract

The invention relates to an adjustable steel pipe scaffold. The adjustable steel pipe scaffold comprises a vertical rod and a cross rod, wherein the vertical rod is composed of a plurality of verticalrod unit pieces, and the cross rod is composed of a plurality of cross rod unit pieces. Each vertical rod unit piece comprises an upper half rod body and a lower half rod body, and the lower half rodbodies can be rightly inserted firmly in the upper half rod bodies. Disc buckles are arranged at the upper end and the lower end of each upper half rod body in a sleeving mode correspondingly, a plurality of mounting holes are evenly distributed in each disc buckle, each cross rod unit piece comprises a first end rod body, a middle rod body and a second end rod body which are sequentially connected in an inserted mode, each middle rod body at least comprises a connection rod body, each connection rod body comprises a first connection section and a second connection section, one end of each first end rod body is fixedly connected with a screw rod, each first connection section is rightly inserted firmly in the corresponding first end rod body, each second end rod body comprises an inserting section and a fixed section, each fixed section is fixedly connected with a screw rod, and each inserting section is rightly inserted firmly in the corresponding second connection section. The adjustable steel pipe scaffold is convenient to mount, dismount and transport, and wide in application range.

Description

technical field [0001] The invention relates to a scaffold, in particular to an adjustable steel pipe scaffold. Background technique [0002] Scaffolding is an indispensable and important construction tool in the construction industry. It is mainly used for construction workers to work up and down, peripheral safety net enclosures and high-altitude installation components. In the early days of the founding of New China, scaffolding in my country was mainly made of bamboo and wood materials. my country has introduced steel pipe scaffolding, which has brought the development of scaffolding technology into a new stage; with the overall development of my country's construction industry, various formwork support frames have been popularized in construction, including fastener-type steel pipe scaffolding, portal scaffolding and recent years. A batch of buckle-type and bowl-type scaffolding that emerged in the future are the most widely used. [0003] Fastener-type steel pipe scaffo...

AI Technical Summary

Problems solved by technology

[0003] Fastener-type steel pipe scaffolding is a scaffold that splices vertical and horizontal steel pipes together with bolt-fastened fastening connectors; fastener-type steel pipe scaffolding has the advantages of convenient assembly and disassembly and strong applicability during construction, and is widely used in engineering In practice; but there are still defects such as fasteners are easy to lose, and the connection quality of fastener nodes is significantly affected by the quality of the fastener itself and the operation of workers; at the same time, the safety of this type of scaffold is low, and the collapse of the fastener-type steel pipe scaffold Accidents happen frequently

[0004] Portal scaffolding is composed of portal frame, cross support, connecting rod, hanging buckle scaffolding board or horizontal frame, locking arm, etc., and then set horizontal reinforcement rod, scissors brace, sweeping rod, sealing rod, bracket and base And adopt a standardized steel pipe scaffolding that connects the wall parts to the main structure of the building; the portal scaffolding has a reasonable structure, good mechanical performance, can make full use of the strength of the steel, and has a high bearing capacity; but the frame size has no flexibility and the price is relatively expensive , the economy is not high

[0005] As a new type of scaffolding, disc-buckle scaffolding and bowl-buckle scaffolding have been widely used in practical projects in recent years. Compared with traditional fastener-type scaffolding and door-type scaffolding, the connection method is novel and reliable, and the assembly and disassembly speed is fast. Scaffolds of various specifications can be built according to different actual needs; however, in the face of industrialization of construction and high labor costs, this type of scaffold still has a low degree of standardization of component sizes, serious restrictions on component size and high component quality And other issues
