Description

Scaffold structure, scaffold joint and quick installation self-locking type shaping scaffold

Technical Field

The patent of the utility model relates to a scaffold frame, concretely relates to scaffold structure still relates to a scaffold frame connects and installs from locking-type design scaffold frame fast.

Background

The scaffold is a framework system temporarily erected for meeting the requirements of construction operation in engineering construction, the steel pipe scaffold is a scaffold form commonly adopted in constructional engineering, and the stability of the scaffold depends on the safety of workers, the construction progress quality and the construction cost. The steel pipe scaffold technology is introduced as early as seventies in China. Along with the high-speed development of the building industry in China, the scaffold theory and the application also obtain the system development, wherein a fastener type scaffold, a bowl type scaffold, a disc type scaffold, a wheel type scaffold and a gate type scaffold are the mainstream steel pipe scaffold forms at present.

Scaffold: the building construction scaffold is composed of a rod piece or a structural unit and accessories through reliable connection, can bear corresponding load, has a safety protection function, provides a structural frame body of operation conditions for building construction, and comprises an operation scaffold and a support scaffold.

The scaffold mainly comprises a fastener type scaffold, a bowl buckle type scaffold, a disc buckle type steel pipe bracket, a door type steel pipe scaffold and the like,

the conventional fastener for steel pipes of the fastener type used for scaffolds is difficult to ensure the connection reliability, and the tightening torque of the fastener bolt is up to 65 N.m, so that the fastener cannot be damaged, and the torque is between 40 and 65 N.m when the fastener is used, as specified in Steel pipe scaffold fastener GB 15831. To the control of tightening torque, the scene mainly relies on specialized tool torque wrench to guarantee, however the torque wrench that the scene was equipped with has quantity not enough, misuse, execution dynamics a great deal of problem such as not enough, is difficult to guarantee to the tightening torque of fastener bolt.

On the main node (the connection point of the three rods of the longitudinal horizontal rod, the transverse horizontal rod and the vertical rod), there is an eccentricity, according to the force transmission path: scaffold board → horizontal pole → vertical pole, there is certain distance (at least one pipe diameter) between vertical pole axis and vertical pole axis, and the eccentric distance condition can't be avoided when the vertical pole atress exists. The auxiliary assembly management is troublesome, and the fastener is at the use, and on-the-spot except categorised right angle fastener, rotatory fastener, the butt joint fastener of being equipped with, easily loses when using and demolising, must be equipped with specialized tool torque wrench in the use.

If the traditional bowl buckle type node is adopted, although the defect of the buckle type part is overcome, the defects that the bowl buckle of the node is easy to deform and the U-shaped connecting pin is easy to lose exist. The existing disk buckle type connecting node overcomes the defects of a buckle type part, and has the defects of more auxiliary accessories and lost bolts. The door type scaffold has poor safety guarantee, low construction efficiency and limited application in basic construction engineering.

By adopting the traditional scaffold connecting node structure, more structural parts are easy to lose, and the management difficulty is increased; the node safety is difficult to guarantee; the construction process is more, and the work efficiency is low.
