  • the anchor members 70 are likewise in the form of strong steel rods, whose bottom ends are screw threaded and are screwed into the holes 35, with a respective lock nut 73 on each rod 70 tightened against the top of the male part-joint plate 31 to prevent the anchor rod becoming loose and unscrewed.
  • the upper .anchor members 70 are embedded in the concrete of the column 60 during the casting of the column 60, so as to anchor the male part-joint 30 to the bottom 61 of column 60.

  • a given structure is to be, say, four columns high, then the columns themselves are preferably cast in lines of four; a record is made of the serial numbers of the three pairs of part-connectors between the four columns, and the relative order in which they are connected together; the columns (and/or connectors) may be marked in some way so that their relative rotational or angular positions before disconnection are known; and the four columns are temporarily stored, or racked, after being cast, in individually known positions, so that the columns can be individually retrieved later, as and when they are wanted, for eventual erection in the self-same lines of four columns each. This is best done by keeping records on computer.
  • this structure may for example have, at each level, longitudinal rows of, say, six columns each and transverse rows of four columns each, so that there are twenty- four columns at each level. This means that one has to cast twenty-four lines of columns with four columns in each line.

If the individual location in storage of each column is sufficiently reliably recorded, individual marked identification of each column, and/or of the part-connectors 20, 31 becomes superfluous, and vice versa. However, it might be thought prudent to identifiably mark each column, and/or the part-connectors 20, 31 in any case, in order to ensure correct connection subsequently.
  • a modified method of casting the columns instead of casting all four columns 50, 60, 92 and 93 simultaneously, they are cast in stages, for example, one or two (or even three) at a time. If one wished to cast the columns one at a time, one would start with column 50. Then, after the concrete of column 50 has fully set, one places column 50 adjacent where column 60 is to be cast, with the female part-connector 20 of column 50 already connected to the male part-connector of column 60, and casts column 60. Then, after the concrete of column 60 has fully set, one disconnects it from column 50, removes column 50, places column 60 where column 50 was previously placed, and proceeds to cast column 92 adjacent to column 60 in the same way as column 60 was cast adjacent to column 50.

  • rebars 52' extend correspondingly further along column 50'.
  • sockets (not shown) are embedded in the column in substantially the same way as the sockets 200 in FIG. 24, with the load distributed through the column by bent rebars similar to the rebars 204, 206 and 208 of FIGS. 24 and 25; bolts (221) for securing the brackets 220 are then screwed into the sockets.
  • FIG. 28 illustrates a modification to part of FIG. 15 for casting columns 60' and 92'. More particularly, in place of the two stop-end plates 1 1 1 , 1 13 and the struts 1 15 and supports 1 17, there is but a single stop-end plate 1 11 ' which accommodates the connector 20, 31. The small clearance between the adjacent ends of columns 60', 92' is just the thickness of the stop-end plate 11 1 '.
  • FIGS. 26, 27 and 28 is not believed to be as good, overall, as the arrangement described with reference to, and illustrated in, FIGS. 1 to 25. However, it is included in order to show that, although spacing adjacent ends of the concrete columns apart is preferred, it is not absolutely essential.

Abstract

Des colonnes de béton alignées (50, 60, 92, 93) coulées simultanément sont préalablement reliées entre elles par des connecteurs métalliques à deux parties (20, 31), à savoir une partie inférieure (20) ancrée sur chaque colonne inférieure ou au sommet de celle-ci (50, 60, 92) et une partie supérieure (31) ancrée sur chaque colonne supérieure ou au sommet de celle-ci (60, 92, 93). Les colonnes (50, 60, 92, 93) sont ensuite séparées par séparation des connecteurs métalliques (20, 31) et stockées dans un ordre connu, pour être ultérieurement reliées à nouveau dans le même ordre, dans un ouvrage en béton avec plancher en béton. L'ordre en question est le suivant: chaque ligne de colonnes verticales (50, 60, 92, 93) de la structure finale est identique à la ligne de colonnes verticales (50, 60, 92, 93) coulées au tout début de l'opération. Dans l'ouvrage proprement dit, une fois que le premier niveau de colonnes (50) a été dressé, on pose le premier plancher de béton (56) sur les sommets des colonnes (50) en remplissant l'espace compris entre le sommet (55) de chaque colonne inférieure (50) et une plaque (21) faisant partie de la partie inférieure du connecteur (20), de telle sorte que ladite plaque (21) se trouve à fleur de la surface supérieure (58) du plancher (56), ce qui permet d'aligner la deuxième colonne (60). On dresse ensuite le deuxième niveau de colonnes préablablement moulées (60) en reliant les connecteurs métalliques (20, 31).
