Design data structure: fastener type steel pipe scaffold planks laid rules

Design data structure: fastener type steel pipe scaffold planks laid rules
(1) the scaffold should be covered, spread, leave the metope of 120 ~ 150 mm.
(2) the docking or lap shall conform to the norms. Scaffolding probe diameter of 3.2 mm galvanized steel wire fixed on the supporting rods.
(3) in the corner, ramps platform of scaffold board and mouth should be connected to the transverse horizontal pole reliable, prevent slippery.
(4) from the top operation layer under the scaffolding of plan, appropriate every 12 m spread a layer of scaffolding.

Frame Scaffolding Used in the Construction Site

图片
Scaffolding is mainly composed of main frame, horizontal box, cross brace frame scaffolding, adjustable base, etc. Frame scaffold first developed by the United States, and 60 s, Europe, Japan and other home has application and development of this type of scaffolding. Frame scaffolding  with simple installation and load-bearing performance good, safe and reliable use, etc. Frame scaffolding in all kinds of new type of scaffolding, the earliest development, use the most, also in Europe and the United States, Japan and other countries, its consumption accounts for about 50% of all kinds of scaffolding. Beginning in the late 70 s, China successively introduced from Japan, the United States, Britain and other countries and the use of this scaffolding. Frame scaffolding a variety of uses: used for buildings, halls, Bridges, overpass, tunnel and other template supporting roof or fly die within the frame. For high-rise building inside and outside the gate scaffolding. Used for mechanica...

Construction safety management: fastener type steel pipe scaffold erection of safety technical requirements

Construction safety management: fastener type steel pipe scaffold erection of safety technical requirements According to the use of the experience at home and abroad and economic rationality, single pipe column the fastener scaffold erection height should not be more than 50 m. More than 50 m high has the following two common practice: 1) the lower part of the scaffold with double tube pillar, upper with single pipe column, single pipe section height under 35 m. 2) halved the scaffold from the bottom of the column, column from the standing on the height of the larger under 35 m.

Housing construction project: scaffolding working conditions have what characteristic

图片
Housing construction project: scaffolding working conditions have what characteristic 1, by load variation. 2, fasteners, belong to semi-rigid connection nodes and node rigid size is associated with fastener quality, installation quality, node performance there is a big variation. 3, scaffolding structure and component of initial defects, such as initial bending of bar, rust, erection size error is larger, the eccentric load, etc. 4, and the wall connection, bigger binding variation on the scaffold. The above accumulation and statistical data, the study of the problems of the lack of system does not have independent probability analysis condition, so the structural resistance adjusting multiplied by the coefficient of less than 1 its value system with using the safety factor of the calibration. Therefore, the specification adopts the design method of essentially belongs to half probability, half experience. The structure of the scaffold to satisfy the provisions of this specificati...
