A multiple support wall structure according to the present invention includes: a pair of top and bottom support plates that has a plurality of rectangular projective islands separated by lattice-shaped projections protruding in the shape of a go board, and protruding upward in the opposite direction to the lattice-shaped projections; and a intermediate reinforcing plate that is disposed between the top and bottom support plates, has upward projective insertions protruding in a shape corresponding to the rectangular islands to be fitted in the rectangular islands of the top support plate, has top grooves formed laterally and longitudinally between the upward projective insertions to fit the lattice-shaped projections, has downward projective insertions formed in the same shape as but in the opposite direction to the upward projective insertions in spaces diagonally adjacent to the upward projective insertions, and has bottom grooves formed laterally and longitudinally between the downward projective insertions.

The present invention relates to a double backbone core for automated hollow door manufacture and a door comprising same. The double backbone core comprises an expandable core component comprising two backbones with relatively smaller cells running parallel to one another along the length dimension of the door, wherein the core is formed from a plurality of interconnected strips.

A double wall panel member for use in a panel wall is provided which includes a tongue-configured end and a groove-configured end. The panel member includes a first outer wall spaced laterally from a second outer wall, and the groove-configured end has a first groove wall portion extending from the first outer wall and a second groove wall portion extending from the second outer wall, where the first groove wall portion extends further outward than the second groove wall portion. When connected, the wall panel members are assembled with the groove end pointing or oriented upward (not downward) and the tongue end pointing or oriented downward (not upward).

For forming a sound absorption/insulation honeycomb panel by stacking an air-permeable material, a honeycomb material filled with a sound absorption material and a reflector, and adhesively joining these materials, it is hard to join the honeycomb material and the air-permeable material adhesively due to a thin wall surface of the honeycomb material and a resultant line to surface adhesive joint therebetween, causing a problem of low adhesive strength. By using a water absorption honeycomb material, an adhesive joint is formed with an adhesive joint area increased by dipping an end of a wall surface of a cell forming the water absorption honeycomb material into a water-soluble adhesive, making the end flexible over a fixed period of time, and then pressing the end strongly against an air-permeable material as a counterpart of the adhesive joint to deform a tip into an inverted T-shape.
