STEEL

Case study : Centre Pompidou Paris, France (1971-1977) Post Modern

In order to think beyond the basic joints such as welding, nut and bolt and screws. Case studies of famous steel buildings were taken to understand how a joinery can also work in different ways.

WOOD

LAP JOINT WITH MORTIS AND TENON As an inital exercise to get familiar with the material, a joinery was choosen and then made by us in the workshop.

Here a Basic Lap joint is made, which then is locked by a third member.

The joint is basicaly a furniture joint, mostly used in beds, chairs and cots. But if the size of members is increased it could also be used in buildings, the vertical member acts as column while the horizontal members become the beams.

LIMITATIONS: Could only be used at right angled edges.

WOOD

MODIFIED LAP JOINT AIM: To use smaller sized members and to have a system that allows the structure to expand at different angles.

In order to overcome its limitation, new joint was made, which allows expansion in many directions, which thiss change in the module, now when its repeated, allows a formation of flat truss system , which could be used as an over hang ceiling .

LIMITATION: Alot of wood is being scooped out.

WOOD & STEEL Joinery allowing multi-angular grid Limitation of previous joint was tried to be overcome by adding steel to play, here a simple joint is made which allows expansion in multiple directions similar to lap joint, but also has a flexiblity of angles.

All the members being attached with a pin joint, have opportunity of having different angles, which are then fixed when module is repeated.

LIMITATION: Could only expand in a flat plane and not go in third dimension.

10

Multiplying the module

Single module

Single module has a pin joint and can have different angles as desired, while multiplication of the modules, the joint gets fixed.

Building a form 11

RECIPROCAL FRAME Further solving the problem

The previous module could not form a three dimensional form, going in similar direction, considering lap joints, reciprocal frame structures were studied and researched upon.

Reciprocal structures were choosen beccause they fullfill both the criteria of using small size member and expansion in multiple directions.

12

Understanding different possible grids to form a reciprocal structure

Forming a 3D form by mixing two grids.

Red marked frame is the idea derived from the process of multiplying the grid further.

13

FRAME ITERATION Deriving a square frame that can create an easy reciprocal From the process of making and research of trying different reciprocal frame structures, this joinery frame came into action, where a simple steel square frame can be used to make a reciprocal frame.

Steel is taken for the frame because the structure would be under emense pressure when loaded, so for stability steel suits best.

Each frame gives different angles and different lock to the reciprocal member.

14

The gap marked in red determines the angle reciprocal member will get, less the gap steeper the angle.

The more radius of the curve allows the reciprocal member to rest properly

FORMATION OF MODULE Adding Bamboo to frame

Further Bamboo sticks are added to the square module, members in one square frame are locked by near next square frame by reciprocal system.

One module needs 5 such square to form a stable structure, when this module is repeated, a further bigger space is created.

LIMITATION: Ground clearaance is realy less in comparision to the members used.

MODULE ITERATION Changing the module to increase floor space

PLAN

The arrangement of modules is changed by bring a new square frame in play, which gives a more slant angle, creating more space on the ground.

JOINERY DETAILS FRAME DETAIL 12 MM MS Square Rod is used to make the frame.

Particular Radius is given to the edge, which helps the bamboo to rest properly.

BAMBOO TO FRAME DETAIL Bamboo with 6cm dia is taken here in the module

21

BAMBOO TO SHADING CLOTH Leminated cotton canvas cloth is used for shadding.

Loop in the cloth

Dome nut

The cloth has a loop at its edges,these loops are hung in a dome nut, thereby being locked onces fixed.

BAMBOO TO GROUND The end condition has a pin joint so as to allow the angular moment for the Bamboo Which is attatched to a 12mm steel plate so that its fixed to the ground.

FINAL MODEL - 1:10 scale

23

ADDING LAYERS Foundation, plinth & roofing

By fixing the module to the ground and by adding roof to the structure, it creates a place for shade with a clear ground space.

As a singular unit, structure can be used for making a pavilion

24

POLY-FUNCTIONALITY Depending on number of modules

When the modules are repeated, a temporary structure is formed with a huge ground clearance, this structure can then be used in situations of MELAS, CIRCUS, PUBLIC GATHERINGS.
