Problems solved by technology

The calculation conclusion of the relevant design manual shows that when the length of each lifting unit of the scaffold is six meters and the height of the frame is about 16 meters (covering five floors), the dead weight of the moving part reaches 45-65kN, accounting for about 80% of the total mass of the scaffold. This directly increases the difficulty of scaffolding installation, storage and transportation, and also has a direct impact on the safety, efficiency, and energy consumption of high-altitude lifting operations.
[0005] 2. With the improvement of modern design and construction level, high-rise commercial and residential buildings tend to be diversified in terms of structure and shape. The frame design of traditional scaffolding lacks technical statistics on the relevant dimensions of modern buildings, and it is difficult to adapt to various Due to various building shapes, it is difficult to assemble and disassemble the scaffold body; especially the size and structure of the bottom truss are single, and when encountering cornices, balconies, etc. protruding from the building's outer wall structure, or local changes such as non-right angles and arc turns, the scaffolding has to be aligned On-site cutting and re-welding of the body, not only labor-intensive and time-consuming, but also difficult to ensure safety design requirements

Embodiment Construction

[0059] In this embodiment of the guide rail-attached scaffold assembly frame structure, the main column and the truss frame are assembled by rods, frames and connectors.

[0060] In this example, the rod and frame are made of an aluminum alloy tube with an outer diameter of φ48mm and a wall thickness of 3.5mm.

[0061] The connecting bolts used in this example are all M16 bolts.

[0062] Rod 1 such as figure 1 as shown, figure 1 1a is the front view of the bar, and 1b is the side view of the bar. The two ends of the bar 1 are stamped into a plate with a width of 72mm to 74mm. There is a longitudinal long hole 18mm×22mm in the center of the plate. Symmetry, front and rear symmetry. Divided into connecting rod 11, main column horizontal tie rod 34, main column diagonal tie rod 33, main column side tie rod 35 and bottom truss horizontal tie rod 24, bottom truss diagonal tie rod 23, bottom truss side tie rod 25 according to length.

[0063] The frame parts are divided into bot...

Abstract

The invention provides a guide rail type assembling frame body structure attached with a lifting scaffold. Each of a main stand column and a bottom truss is formed by assembling rod pieces, frame pieces and connecting pieces. Each frame piece is provided with upper and lower connectors and connecting wings; the rod pieces are connected with the frame pieces through the connecting wings to form cuboid basic units; the basic units of the main stand column are connected in a downward extending way through the upper and lower connectors to form the main stand column; the basic units of the bottom truss are connected through the connecting pieces in a transversely extending way to form the bottom truss; a main frame body is formed by connecting the main stand column and the bottom truss; and the upper and lower stand columns of the bottom truss of the main frame body are connected through a basis rod piece and a buckling piece, so as to finally form the guide rail type assembling frame structure attached with the lifting scaffold. The rod pieces and the frame pieces are made of tubular products. Vertical long-hole plate sheets are arranged at the centers of two ends of the rod pieces. The frame pieces are divided into a bottom truss frame piece, a bottom main stand column frame piece and an upper main stand column frame piece. A frame body disclosed by the invention is assembled by the standard frame pieces and the standard rod pieces and is convenient to store; and the total weight of equipment is low, the stability is improved, the variety of components is reduced and the batch production is easy to realize.

Description

technical field [0001] The invention relates to the technical field of lifting scaffolds for high-rise and super high-rise building construction, in particular to a rail-type assembled frame structure attached to lifting scaffolds. Background technique [0002] At present, the guide rail attached lifting scaffold has been widely used in the construction of high-rise and super high-rise buildings. This kind of lifting scaffold mainly includes three parts: frame structure, attached load-bearing structure and control system. The frame structure part includes vertical main columns, horizontal bottom trusses and connectors; the attached load-bearing part includes load-bearing beam system, guiding system, anti-fall system, etc.; the control part includes strong and weak current systems controlled by computer. The load-bearing beam system of the equipment is fixed on the load-bearing components of the building, and the jack is installed between the load-bearing beam and the frame ...
