Escalib Mills MDs*: spiral staircase with side exit... he Escalib is a metal spiral stair tower with a side exit. The triangular step acts as a landing. in order for the steps to be leveled with the desired floor, a 90° rotation or more might be necessary. The stair tower is composed of a base, with 1 to 8 modules that are easy to assemble with a crane and a barrier gate at the top (maximum height 20m10). The build which uses only collective protection (no safety harness) is simple and fast with only 4 screws per module. Each module is fitted with fold-away guardrails that are attached at...

High performance and strength... o make it easier to size the anchor points and ground bearing for the Escalib, the ground load calculations and the forces at the anchor points are given for the various configurations. Assumptions: I - Wind action as in EN 1991-1-4: - f = 0.23 and Cf = 2.73 - vp : Wind speed (km/h). - qp : Peak wind pressure (daN/m²). 2 - Working load Q: - 8 persons per Escalib Mills module. - Up to a maximum of 20 for the complete stair tower. - Stair tower not to be used for winds of over 65 km/h. 3 - Weight (P) of Escalib Mills. if “d” is greater than 20 cm, wind bracing...

Example: An 8-module Escalib located in Paris is subject to a peak wind pressure qp of 54 daN/m2, corresponding to a wind speed of 107 km/h. In configuration I, the Escalib Mills is anchored every 3 modules. Each anchors must withstand the following stresses: - shearing: V = 300 daN, - pullout:T = 200 daN. “No entry” is displayed until the inspection report has been completed and inserted into the plastic pocket. NB :The holes drilled in the foot plates are to be used to nail through to wooden blocks when it is necessary to spread the load on the ground. They must not be used to anchor the...
