MECHANICS

5. ANCHORING

The anchors were chosen from a catalogue, making

sure their capacity would be able to support the selfweight

and the applied loads in the module.

They are two types of anchors. The first, connecting the

existing building to the U profile which is connected

to the module, is 10 mm diameter and 150 mm long,

attaching itself to the existing structural column. The

second type connects the U profile to the back plate

of the module. It is also 10 mm diameter and 50 mm

long. Using a steel metal sheet, bolts on both ends fix

the elements together.

6. U-PROFILE

The dimensions of the U-profile running along the

back face of the back plate of the module, where

dimensioned according to the necessary properties

for the anchoring earlier discussed. In such case, the

U-profile consists of a UAP (UPA 150X75X6), leaving a

150 mm gap in between the modules and the existing

building. In order to verify the profile was appropriate

for the loading conditions, the stress was calculated

according to the sectional area of the profile, and then

compared to the allowable stress for steel.
