1. Design purpose

The Box_Wood_Frame design is a solid and cost effective piece of furniture that can be piled up.

_images/pile_up_of_pieces_of_furniture.png

The pile-up feature is useful for:

  • rearranging interior
  • transporting the pieces of furniture
  • moving accommodation
  • And also, maybe, building straw house
  • it lets make big pieces of furniture out of small pieces of material
  • the conception is also cut in several small problematics
  • the big pieces of furniture can be easily dismount, transport and remount

The frame is made out of solid wood planks. The faces can then be closed with light plywood.

A module corresponds to one or several box of the grid. We focus on the concatenation of box along the x axis. N is the number of concatenated box (along the x axis).

2. Construction method

The planks are fixed by crenel and glue.

3. Design proposal

Wood frame plank list:

  • horizontal plank: 20x60
  • vertical plank: 20x30
  • diagonal: 10x30 (thiner to give space for the face plywood)

4. Box wood frame parameters

A module is defined by:

  • The box dimension (w*d*h): 300*300*300
  • The number of aggregated box: N*1*1

N is the length of the module. It is a number of boxes.

5. Plank outline description

Q is the number of required planks to build one module. It can depends on N, the length of the module.

5.1. plank01_xz_bottom

Q = 2

5.2. plank02_xz_top

Q = 2

5.5. plank05_z_side

Q = 2*(3+N)

5.6. plank06_zx_middle

Q = 2*(N-1)

5.7. plank07_wall_diagonal

Q = 4*(1+3*N)

5.8. plank08_tobo_diagonal

Q = 8*N

5.9. hole_cover

Q = 8*(N+1)

The plank09_hole_cover has an aesthetic functionality.

6. Diagonal plank reorientation

The planks are positioned in the cuboid assembly with the plank_place() function. To position the diagonal planks with this function, the diagonal planks must first be rotated of 45 degrees and affected with virtual length and width corresponding to the assimilated straight plank.
