Perforated Sliding Bearing Type Z

By suitable selection of the bearing thickness, the bearing can accommodate large vertical forces as well as large rotational deformations. 

The splitting tensile stresses are calculated taking the provisions of DIN 4141, Part 14 Section 5.2 in accordance with Book 339, DAfStb.

Installation

In precast construction, all types of Perforated TM Bearings are placed centrally on the bearing support surface and no special constructional measures are required. This applies whether the bearing module is below or on top. In in-situ concrete construction, the edge distance to the outside edge of the structural elements must be at least 40 mm and the plan area of the bearing must be enclosed by reinforcement. Any chamfers on the edges of structural elements must be taken into account in determining the edge distance. (Figure 5)

Attention should be paid to the following:

• The sliding direction of the bearing must align with the movement direction of the structural element.
• In in-situ construction, the sliding gap must not be concreted over.
• The bearing must always be able to slide.
• In steel and timber construction, the edge distance must be at least 40 mm.
