Description

Assembled scaffold

Technical Field

The utility model relates to an assembled scaffold.

Background

The scaffold is a working platform which is erected for ensuring that each construction process is smoothly carried out. The scaffold is divided into an outer scaffold and an inner scaffold according to the erected positions; the scaffold can be divided into a wood scaffold, a bamboo scaffold and a steel pipe scaffold according to different materials; the scaffold is divided into a vertical rod type scaffold, a bridge type scaffold, a door type scaffold, a suspension type scaffold, a hanging type scaffold, a lifting type scaffold and a climbing type scaffold according to the structural form.

In the early 80 s of the last century, various types of scaffolds such as door type scaffolds, bowl-buckled scaffolds and the like are introduced from foreign countries in China. The door type scaffold has been widely applied in many domestic projects to obtain better effect, and the door type scaffold is not widely popularized and applied due to the product quality problem of the door type scaffold. A lot of door type scaffold production plants are built in China, and most products are processed according to the drawings of foreign merchants. The bowl-buckled scaffold is the most popularized scaffold in novel scaffolds, but the use range is not wide, and the scaffold is only applied in partial regions and partial projects.

Since the 90 s, some domestic enterprises have introduced foreign technologies, and developed various novel scaffolds, such as bolt-type scaffolds, CRAB module scaffolds, disc-type scaffolds, square-tower scaffolds, and various types of scaffold. In 2013, domestic professional scaffold production enterprises have more than one family, mainly in areas without stannum, Guangzhou, Qingdao and the like. Technically, scaffold enterprises in China already have the capability of processing and producing various novel scaffolds. But the domestic market has not yet formed, and the knowledge of construction enterprises to novel scaffold is not enough yet.

With the appearance of a large number of modern large-scale building systems in China, the fastener type steel pipe scaffold can not meet the requirement of building construction development, and the rapid development, popularization and application of the novel scaffold are urgent. Practice proves that the novel scaffold is safe and reliable in construction and high in assembly and disassembly speed, the steel consumption of the scaffold can be reduced by 33%, the assembly and disassembly efficiency is improved by more than two times, the construction cost can be obviously reduced, and the construction site is civilized and neat.

The scaffold boards are also called scaffold pieces and are laid on scaffolds and operation frames, so that workers can walk above the scaffold boards, transfer materials and construct construction work conveniently, and the scaffold boards are a building material which can be used for temporary turnover. The scaffold board can be made of steel, wood, bamboo, aluminum alloy, plastic and other materials.

Wooden scaffold boards are the most common type of scaffold boards, and are often made of fir or pine. The thickness of the wooden scaffold board is not less than 50mm, the width of the board is 200-250 mm, and the length of the board is 3-6 m. In order to prevent the end of the scaffold board from being damaged in the using process, 10 # iron wires can be tightly hooped at the positions 80mm away from the two ends of the scaffold board, or iron sheets with the thickness of 0.4-0.6mm are used for wrapping and hooping. Wooden scaffold boards are commonly used for bamboo, wooden scaffold, fastener-type steel pipe scaffolds and independent chutes with large loads, and are less used for movable scaffolds, various tool-type scaffolds and door-type scaffolds. The wooden scaffold board has the characteristics of wide application range, simple paving method, convenient disassembly and better foot feeling of constructors in use. As the environment protection policy is vigorously pursued in the country in the past, the sources of materials are relatively reduced, and the usage amount of the materials is gradually reduced year by year.

The bamboo basketry sheet scaffold board is the most common scaffold board in southern areas and is usually made by longitudinally splitting adult moso bamboos or phyllostachys pubescens in more than two years of growth period into bamboo sheets with the width of 30 mm. The longitudinal ribs of the bamboo basketry sheet scaffold board are not less than 5, each channel is double, the transverse ribs are reversely and alternately arranged, and the intersection points of the longitudinal ribs and the transverse ribs at the end parts of the four sides are firmly tied by iron wires through the drilled holes. And binding two double-sided reinforcing bars with the width of 40mm with iron wires along the longitudinal direction of each bamboo basketry piece scaffold board, and fixing the bamboo basketry piece scaffold boards by round nails. The bamboo basketry board has a length of 1.5-2.5 m and a width of 0.8-1.2 m. When the bamboo basketry sheet scaffold board is used for an inclined road board, the transverse ribs are used as the longitudinal ribs and are used as anti-skid measures. Bamboo basketry sheet scaffold boards are commonly used for laying bamboo and wood scaffold, fastener type steel pipe scaffold and chute, and have the advantages of wide material source, low price and convenient assembly and disassembly, but have the defects of dense spacing of bearing rod pieces, easy adhesion of construction waste, poor strength and less turnover times.

The bamboo string piece scaffold board is a common scaffold board. Adult moso bamboo or phyllostachys pubescens in the growing period is split into bamboo chips with the width not less than 50mm, and is made by screwing bolts through the parallel bamboo chips, the length of the bamboo string chip scaffold board is 2, 0-3. Om, the width is 0.25-0.3 m, and the board thickness is not less than 50 mm. The bamboo string piece scaffold board is suitable for bamboo, wood and fastener type steel pipe scaffolds, and has the characteristics and the application range similar to those of the bamboo basketry piece scaffold board, but the strength and the turnover use times are slightly larger than those of the bamboo basketry piece scaffold board.

Steel plate scaffold boards are a common type of scaffold board. The angle steel scaffold plate and the hot-dip galvanized steel scaffold plate are divided, and the angle steel scaffold plate and the angle steel screen plate are corrosion-resistant and anti-flaming hot-dip galvanized steel springboards.

The stair installed on the existing scaffold is mostly of an integrated structure, the structure is not only self-heavy, and is difficult to install, but also the whole stair needs to be replaced together once the parts on the stair are damaged, and the maintenance cost is greatly increased.
