Bailey Type Bridge Scaffolding Rigid And Flexible Structure And Strong Impact Resistance
Introduction of Bailey Type Bridge Scaffolding
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.
Fabrication and Components:
The steel components for Bailey bridge scaffolding, such as chords, transoms, and bracing members, are precisely fabricated using techniques like cutting, punching, and welding.
Standardized, interchangeable components are produced to facilitate rapid assembly and disassembly on-site.
Strict quality control measures are implemented during the fabrication process to ensure dimensional accuracy and structural integrity.
| Comparison of technical performance of support construction | ||
| Support type | Bowl buckle type full hall bracket | Bailey beam column bracket |
| Stress structure | The force condition is simple, and the force analysis is relatively simple. | The way of force transmission is clear, but the force analysis is complicated. |
| Safety performance | When the height is too high, it will affect the overall stability, and when the geological conditions are complex, the foundation treatment workload is large, and the uneven settlement will reduce the overall safety. There are more construction personnel, large labor intensity, easy to occur safety accidents, single components, poor impact resistance. | The large number of components is small, it is easier to ensure the construction safety, the use of machinery is more, easy to occur mechanical safety accidents, the structure is rigid and flexible, and the impact resistance is strong. |
| Topographic condition | When the terrain is steep, it is difficult to smooth the surface, and it is too difficult to deal with the rock-soil joint. | Less topographic influence. |
| Difficulty of construction | It is difficult to deal with the foundation, and easy to set up and remove the support. | The construction situation is more complicated, the lifting of components is difficult, and the dismantling is not easy. |
| Economic performance | The basic processing cost is high, the material input is large, but it is more single, The number of personnel requirements are large, the investment in mechanical equipment is relatively small, the construction speed is slow, the total cost of the bracket is high, and the economy is low. | The basic processing cost is relatively low, the material investment is relatively less, but the form is more, the personnel requirements are less, but the quality of personnel is high, the mechanical equipment investment is larger, the construction speed is faster, the total cost of the bracket is lower, and the economy is higher. |
| Performance of Bailey Bar | ||||
| Name | Materials | Cross section pattern | Cross-sectional area (cm2) | Theoretical allowable Carrying capacity (kN) |
| Chord | Q355 | ][10 (Channel steel) | 25.48 | 560 |
| Vertical bar | Q355 | I 8 (I Steel) | 9.52 | 210 |
| Diagonal bar | Q355 | I 8 (I Steel) | 9.52 | 171 |
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.
Maintenance and Inspection of Bailey Type Bridge Scaffolding :
Regular inspections of the Bailey bridge scaffolding are crucial to identify any damage, wear, or deterioration of the components.
Preventive maintenance, such as touch-up painting or component replacement, is carried out to maintain the structural integrity and safety of the bridge.
Record-keeping and documentation of the bridge's history, including any repairs or modifications, are essential for ensuring its reliable performance.
Application of Bailey Type Bridge Scaffolding
Disaster Response and Recovery:
Providing temporary bridge solutions in the aftermath of natural disasters, such as floods, earthquakes, or landslides.
Enabling emergency access and restoration of transportation links during crisis situations
Temporary Bridge Construction:
Constructing temporary bridges during the construction or repair of permanent bridge structures.
Providing a cost-effective and efficient solution for short-term bridge requirements, such as during road construction or maintenance.
