Connection Strapping

Manufacturer: Hellermann Tyton Product: Stainless Steel Cable Tie Type: MBT14XH (Metal Ball bearing Ties) Material: Stainless Steel Type SS316 Length:362mm, Width:12.3mm, Thickness:0.3mm Min. Tensile Strength: 715, 3200lbs Quantity: 148

Manufacturer: Hellermann Tyton Product: Cable Tie Installation Gun Model: MK9SST (Installation tool will be made available to rent from bamboo housing supplier)

A similar connection strapping system will be sourced in India to ensure cost effective construction of the bamboo house. The system should be validated to guarantee strength and usability.

Creating a Connection

At the point of purchase, a demonstration will be given detailing, how to select appropriate bamboo, how to use the installation gun and how to check that the connection is secure. Key Notes:

Keep the bamboo culms to the outside of the connection plate, apart from the floor beams.

When attaching the 'side' bamboo culms, leave enough space for the central bamboo culm.

Ensure that the cable tie is tightly wrapped around both the bamboo culm and connection plate.

Ensure that the cable tie is not twisted.

Do not over tighten the cable tie; this may cause the bamboo culm to crack

Ensure that the cable tie is properly and firmly crimped.

Modular Bamboo House Construction

The bamboo house structure is modular in design thus allowing multiple structures to be attached together creating a much larger structure. Attaching the bamboo houses together also makes the overall structure more stable as they support each other. The bamboo houses can be attached together with cable ties or with standard construction strapping as seen in the image below.

Product: Construction Strapping Material: Stainless Steel (Grade 304) Width: 10-20mm Thickness: 0.3-0.5mm

The bamboo houses can be clad with various different materials depending on the local resources.
