定义
A structural steel plate component that serves as the primary load-bearing interface between a jib crane's vertical column and the concrete foundation. It distributes operational loads (vertical, horizontal, and moment forces) from the crane structure to the foundation while providing precise alignment and anchorage points for the column base.
工作原理
The foundation plate functions as a rigid load transfer mechanism that converts concentrated crane loads into distributed foundation pressures. It provides a flat, level mounting surface for the jib crane column while incorporating anchor bolt holes for secure attachment. The plate's thickness and dimensions are calculated to prevent bending under maximum crane loads and to maintain structural integrity throughout the crane's operational life.
材料
ASTM A36 structural steel plate or equivalenttypically with minimum yield strength of 250 MPa and tensile strength of 400-550 MPa. Surface may be hot-dip galvanized or painted with corrosion-resistant coatings for environmental protection.
Thickness
20-50 mm
Dimensions
Custom based on crane capacity (typically 600x600 mm to 1200x1200 mm)
Load Capacity
Designed for 1.5x maximum crane load
Surface Finish
Mill scale removed, blasted to Sa 2.5
Anchor Bolt Holes
4-8 holes with 25-36 mm diameter
Flatness Tolerance
±1.5 mm over entire surface
标准
ISO 12488-1DIN 15018ISO 4301-1DIN 4114

常见问题

What is the purpose of grouting under a jib crane foundation plate?

Grout fills the gap between the foundation plate and concrete foundation, ensuring full bearing contact and preventing stress concentrations. It provides uniform load transfer and compensates for minor surface irregularities.

How are anchor bolts sized for jib crane foundation plates?

Anchor bolts are sized based on maximum uplift and shear forces, with typical diameters of 25-36 mm. They must extend sufficiently into the concrete foundation (minimum 12x bolt diameter) and include proper embedment and edge distance per structural calculations.

Can foundation plates be reused when relocating a jib crane?

Foundation plates are generally not reusable due to potential deformation from previous loading and difficulty in removing embedded anchor bolts. New plates are recommended for crane relocations to ensure structural integrity.
