Description
Bailey Type Bridge Scaffolding generally adopts Bailey panel as the bearing member. Compared with the bowl buckle scaffold has obvious advantages. Bailey plate is also called Bailey frame, Bailey beam or truss.
Bailey panel has the characteristics of simple structure, convenient transportation, quick erection, large load, good interchangeability and strong adaptability.
Bailey Type Bridge Scaffolding is composed of steel pipe column, sand box, distribution beam, Bailey beam, bottom mold, side mold and support.
Bailey Type Bridge Scaffolding can be divided into ordinary type and reinforced type.
When the frame is provided with continuous vertical scissor braces from bottom to top at intervals of 5m to 8m along the outer periphery and inside longitudinally and horizontally, continuous horizontal scissor braces are provided at the intersection plane at the top of the vertical scissor braces, and the spacing between the horizontal scissor braces and the bottom plane of the frame or adjacent horizontal scissor braces is not more than 8m, it is defined as a common full-length support frame.
When the spacing of the continuous vertical scissors is not more than 5m, and the spacing of the continuous horizontal scissors is not more than 6m from the bottom plane of the frame or the spacing of the adjacent horizontal scissors, it is defined as a strengthened full-room support.
Steel pipe column
A. Steel pipe columns are generally made of spiral steel pipes with a diameter of 1000mm, which play a role in transmitting the beam structure's self-weight, support load and construction load to the foundation. In order to ensure the stability of the steel pipe columns, the adjacent steel pipe columns are connected with 10-channel steel. The top of the column is supported by the distribution beam, and the lower part is supported on the cap or foundation.
B. The bottom end of the steel pipe column is welded with 10mm thick 110×110cm steel plate, and the four corners are fixed with expansion bolts. In order to strengthen the stability of the steel pipe column, a "well" font support is arranged in the end of the steel pipe column. The top and middle of the steel pipe column are fixed on the pier with 20 channels of steel.
3. In order to facilitate the removal of the bottom die, side die and Bailey beam, an adjustable height sand box is installed between the top of the steel column and the I-steel. The height of the sand box is 0.5m.
4. The distribution beam plays the role of distributing structural load, support load and construction load to the steel pipe column.
5. The single panel Bailey is generally 3m long and 1.5m high, and the Bailey is connected with a pin between the Bailey panels, and the Bailey beam is connected with a flower window to strengthen its torsion resistance
Bailey panels can be used for highway Bridges, assembling gantry cranes, guide beams, bridge erecting machines, hanging baskets, etc. Bailey truss combination gantry crane, the use of prefabricated highway steel bridge components to assemble gantry, and its span and column height can be adjusted to adapt to different work sites, widely used in highway, railway, municipal, construction, water conservancy and other construction projects, bridge construction prefabrication yard lifting and transporting prefabricated components, bridge pier side loading girder and other on-site construction operations.
