Description

Telescopic down tube of adjustable length and disc type scaffold who has this down tube

Technical Field

The utility model relates to a scaffold frame field, concretely relates to telescopic down tube of adjustable length and disc type scaffold frame that has this down tube.

Background

As society continues to advance, the construction industry also continues to advance in new directions. The novel technology, the novel material and the novel process are continuously developed and utilized in the building industry, and the disc type scaffold has wider application prospect due to the advantages of safer and more efficient erection and the like. The disc type scaffold is a novel scaffold, is introduced from Europe in the eighties of the last century, is an upgraded and updated product after a bowl buckle type scaffold, is also called as a chrysanthemum disc type scaffold system, a plug disc type scaffold system, a wheel disc type scaffold system, a buckle disc type scaffold, a LAYHER frame (a leiya frame, the basic principle of the scaffold is invented by Germany LAYHER company, so the scaffold is also called as the leiya frame by the industry), is widely applied to support and storage designs of general viaducts and other projects, tunnel projects, plants, elevated water towers, power plants, oil refineries and other plants and special plants, and is also applied to street-crossing bridges, span shed frames, goods shelves, chimneys, water towers, indoor and outdoor decorations, large concert stages, background frames and stands, viewing platforms, modeling frames, stair systems, stage erection at evening, stadium stands, and the like. The connecting disc of the scaffold is a disc with the diameter of 133mm and the thickness of 10mm, 8 holes are formed in the disc, Q345B steel pipes with the diameter of 48 multiplied by 3.5mm are used as main component upright posts, discs are welded on the upright post steel pipes at intervals of 0.60m, the novel and attractive disc connecting rod is used as a main component, and meanwhile, the bottom of each upright post is connected with an adjustable base. The cross bar is made by welding buckle joints with bolts at two ends of the steel pipe, and the inclined bar is made by hinging the buckle joints with the bolts at two ends of the steel pipe.

However, in the existing disk scaffold market, the inclined rods of the produced disk scaffold are all in common specifications and are fixed in length, so that the non-standard inclined rods cannot be leased and must be purchased in a customized mode, and the construction cost is increased. For example, due to the limitations of field environment and design height, non-standard pitches may occur, such as unusual pitches of 500mm, 700mm, 1000mm, and the like, and at this time, the conventional vertical diagonal bar cannot be used, so that the situation that a support system is incomplete occurs in the erection process, a construction unit has to take reinforcement measures, and resource investment waste and acceptance inspection lag are caused.
