  • the dimensions of the mating pin 410 and the top cavity 501 should be such that: there is an appropriate amount of space between the external surface of the mating pin 410 and the internal surface of the top cavity 501 for good adhesion between the surfaces, the relative alignment of the modules 100 to each other is sufficiently precise, and there is enough space for the adhesive to flow considering the viscosity of the adhesive.
  • the mating pin and adhesive joint system described above for the corner columns 110 can also be applied to joining of the intermediate columns 120 and crossbeams 140 and 146 to corresponding columns in adjacent frame modules 100.

  • the adhesive canister 420 is then placed in the mating pin 410.

  • actuator B540 which is free to move in its bore B404, presses down on the plunger head B423 of the adhesive canister B420, breaking the seals and forcing the adhesive from its canister, causing the epoxy and hardener components of the adhesive to begin to mix as they both pass through the canister outlet into the mixing nozzle.
  • At least one barrier B424 which may be made of a malleable plastic, keeps the two parts of the adhesive separate in an inner chamber B425 and an outer chamber B426.
  • the barrier B424 is cut and peeled back, and the plunger head B423 keeps the inner and outer chambers B425 and B426 sealed as it forces the two parts of the adhesive down through the chambers B425 and B426 and the mixing nozzle B430.
  • the two parts of the adhesive mix together and flow through the mixing nozzle B430, through the nozzle cavity (or dispensing bore) B413, through the horizontal (end face) distribution channels B414 and the vertical (side face) distribution channels B415 to fill an annular volume 900.
  • the annular volume 900 is defined by the outer wall of the mating pin B410, the inside wall of the top cavity A501, the inner end surface of the top cavity A501, and the abutting surface of column base B400.
  • the mating pin arrangement may be used for some or all of the column joints between frame modules. Further fastening systems may also be used to fix the frame modules together at different contact points, and they may be attached to horizontally adjacent modules as well as modules above and below.

Abstract

Des modes de réalisation de la présente invention concernent un module de construction pour une structure de construction et des colonnes de bois de construction et des agencements de raccordement pour de telles structures de construction. Des modes de réalisation exemplaires concernent un module de construction comprenant : une colonne de bois de construction pour agir en tant que support de charge verticale pour le module, la colonne comprenant une partie de mortaise à une extrémité de la colonne et une partie de tenon à une extrémité opposée de la colonne, la partie de mortaise et la partie de tenon ayant des formes complémentaires ; et un conteneur disposé dans l'extrémité opposée est agencé de manière à être actionné en réponse à la réception d'une partie de tenon d'une colonne de bois de construction d'un module de construction adjacent dans la partie de mortaise à une extrémité, le conteneur comprenant un premier composant adhésif dans une première partie du conteneur et un deuxième composant adhésif dans une deuxième partie du conteneur, où, lorsque le conteneur est actionné, les premier et deuxième composants sont amenés à être mélangés pour former une composition adhésive de fixation de bois de construction et distribués pour fixer le module de construction au module de construction adjacent.
