Definitions

  • This invention relates principally to a concrete structure comprising reinforced concrete columns and concrete floors, and to a method of constructing same.
  • the invention also relates however to a metal joint for use in jointing columns together in such a structure, to a method of casting concrete columns, and to a deck unit for use in casting concrete columns.
  • the customary practice at present is for concrete columns to be individually cast in situ, which involves the erection of formwork for each column, pouring concrete into the erected formwork, waiting for the concrete to set and then dismantling the formwork, all of which is time-consuming and labour-intensive.
  • GB 591,431 discloses pre-cast concrete columns which are located above one another. Because reinforcing bars extend from both columns, however, both columns have to be located in situ prior to pouring a concrete floor, for example.
  • FR 1186339 relates to coupling members between concrete columns.
  • GB 1039126 (Laing) relates to joints between structural members.
  • GB 591431 (Lee) relates to reinforced concrete columns.
  • US 5253460 (Simenoff) relates to column assemblies.
  • US 4081935 (Wise) relates to a building structure utilizing precast concrete elements.
  • a first part-joint, or female part-joint, 20 comprises a female part-joint plate 21, a backing plate 22, a locating tube 23 and an end plate 24.
  • the joint plate 21 and the backing plate 22 are welded together, both being substantially square in overall shape as shown in FIG. 1.
  • the joint plate 21 and backing plate 22 are of steel.
  • Joint plate 21 is relatively thick and extremely strong. It is provided with four (or more) holes 25, which are internally tapped or screw-threaded.
  • the joint plate 21 is generally ring-shaped having a relatively wide, circular cut-out 26 with four equiangularly spaced ears, flanges or ledges 27 around the inside periphery thereof.
  • the backing plate 22 extends across substantially the whole of the underside of the joint plate 21, including the hole 26. At the centre of the backing plate 22 is a relatively small hole 28, of substantially the same diameter as, and co-axial with the locating tube 23, which is welded to the underside of the backing plate 22 and depends downwardly from the latter.
  • the end plate 24, as its name suggests, is located at, and fixed to, the bottom end of the tube 23.
  • the backing plate 22 has four (or more) holes 29, which are untapped, in alignment with the holes 25 of the joint plate 21.
  • the female part-joint 20 comprises a stop 30, the function of which will be explained hereinafter, welded to the underside of the end of one of the ears, flanges or ledges 27 as shown in FIGS. 1 and 2.
  • a second part-joint, or male part-joint, 31 comprises a male part-joint plate 32 and a locating pin 33.
  • the male part-joint plate 32 is substantially circular in shape, except for four equiangularly spaced, outwardly projecting, ears, flanges or ledges 34 (adapted to engage the female part-joint 20 between the backing plate 22 and the four ears, flanges or ledges 27).
  • the male part-joint plate 32 is provided with four (or more) internally tapped, or screw-threaded holes 35 which are equiangularly spaced apart. At the centre of the male part-joint plate 32 is a relatively small hole 36.
  • the locating pin 33 has at its upper end a reduced diameter portion 37, which fits inside the central hole 36 of the male part-joint plate 32.
  • the reduced diameter locating pin portion 37 is welded to the male part-joint plate 32 inside the hole 36, so that the male part-joint 31 of FIGS. 3 and 4, like the female part-joint of FIGS. 1 and 2, is effectively a unitary structure.
  • the male part-joint plate 32 is formed by being cut-out from the inside of the female part-joint plate 21, thereby forming the cut-out 26 with the ledges 27 in the latter and forming the ledges 34 in the former.
  • the female part-joint, or first part-joint, 20 When, in use as described hereinafter, the female part-joint, or first part-joint, 20 is mated with the male part-joint, or second part-joint, 31 the bottom surface 38 (FIG. 4) of the male part-joint plate 32 rests directly upon the backing plate 22 (FIG. 2) of the female part-joint 20.
  • the backing plate 22 itself is, in use, backed and fully supported by floor concrete, as will become apparent from the following description.
  • Each female part-joint 20 and each male part-joint 31 is marked with a unique serial number, which has to be visible as the two part-joints 20, 31 are connected together, so as to join together two adjacent concrete columns, in the eventual concrete structure, as will be described below.
  • FIG. 5 illustrated in phantom outline is the upper end 51 of a precast concrete column 50, Also shown in phantom outline (see also FIG. 6) are reinforcement bars, or “rebars”, 52 and cross-links 54, interconnecting the rebars 52.
  • the rebars 52 and the cross-links 54 are embedded in a conventional manner in the precast column 50 at the time of casting the column 50, described hereinafter.
  • the top of the column is referenced 55. Resting upon the top of the column 55 is the underside 57 of a concrete floor 56.
  • the top side 58 of the concrete floor 56 is also shown in phantom outline.
  • the backing plate 22 of the female part-joint 20 is fully supported by concrete of the floor 56, and can therefore support the male part-joint plate 32 (see above).
  • the bottom end 61 of a second precast concrete column 60 is also shown in phantom outline.
  • the second concrete column 60 is cast with rebars 62 and cross-links 64 by way of reinforcement.
  • the reinforcement of the concrete columns 50, 60 is conventional.
  • anchor members 66 are fixed to the joint plate 21 of the female part-joint 20 and anchor the female part-joint 20 to the column 50 by extending downwardly from the joint plate 21 into the concrete of column 50, being embedded therein during the casting of the column 50.
  • the anchor members 66 are in the form of strong steel rods, the upper ends of which are screw threaded as shown and are screwed into the four (or more) tapped holes 25 at the comers of the joint plate 21.
  • a lock nut 68 is strongly tightened against the underside of the joint plate 21 so that the anchor member 66 cannot become loose and unscrew from the joint plate 21.
  • the anchor members 66 project above the top 55 of the column 50, so that the joint plate 21 is spaced above the top 55 of the column 50 (by the thickness of the concrete floor 56).
  • anchor members 70 anchor the male part-joint plate 31 to the bottom end 61 of column 60.
  • 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.
  • the annular bottom base 75 of the upper column 60, surrounding the male part-joint plate 31, is relieved so that, even when the male part-joint plate 31 rests inside the female part-joint plate 21, the bottom face 75 of upper column 60 is spaced above the top surface 58 of concrete floor 56 and does not rest upon the latter, all the vertical load being transmitted through the male part-joint plate 31 to the backing plate 22, backed by concrete of the floor 56.
  • the ears, flanges or ledges 27, 34 of the female and the male part-joint plates 21, 32 respectively function to withstand strong tension forces and/or bending moments at the joint between the lower and upper columns 50, 60.
  • the lower anchor bars 66 are holding the female part-joint plate 21 spaced above the top 55 of column 50.
  • the concrete floor 56 is cast, or laid, so that concrete of the floor 56 completely fills the space between the joint plate 21 and the top 55 of column 50.
  • the concrete is allowed to set, to form the floor 56 as shown.
  • the joint plate 21 is flush with the top surface 58 of floor 56.
  • starter bars there is no need for so-called "starter bars" to project upwardly from the floor 56 to form the next column 60.
  • the top of the floor 56 is flat and uninterrupted by any impedimenta, which can considerably facilitate the use of special machinery, not shown, for placing and finishing the floor slab 56, prior to positioning the next column 60 directly on top of the joint plate 21.
  • the column 60 is simply lifted by crane and positioned directly over the joint plate 20. To locate the position of column 60 laterally, the locating pin 33 of the male part-joint 31 is introduced through the hole 28 into the locating tube 23 of the female part-joint 20. Then the column 60 is lowered, with the ledges 34 being guided past the ledges 27, until the bottom 38 of the male part-joint plate 32 rests upon the backing plate 22, which is supported by the concrete of the floor 56. The column 60 is then rotated through a small angle about its vertical axis, to move the ledges 34 underneath the ledges 27, until one ledge 34 abuts the stop 30.
  • the close manufacturing tolerances of the male and female part-joints 20, 31 result in the lower end 61 of the upper column 60 being held tightly in position and prevent the upper column 60 from leaning over.
  • the concrete base 81 itself is laid. Well before the concrete of the base 81 has been placed, the required position of the column 50 is determined and four vertical bolts 82 inside four respective, commercially available, tubes 83 are embedded as shown in the concrete of the base 81, with the bolt heads 84 resting at the bottoms of the tubes 83 against the undersides of four washers 85.
  • the tubes 83 serve to keep the concrete away from intimate, pressing contact with the bolts 82. so that the bolts 82 can be laterally adjusted in position if necessary, even after the concrete of the base 81 has set, or has started to set.
  • base plate 86 At the time of precasting the column 50, its bottom end 80 has, anchored to it, a base plate 86. More particularly, base plate 86 has, welded to it, four (or more) anchor members in the form of metal bars 87, of which only two bars 87 are shown.
  • the anchor bars 87 just like the anchor bars 66, 67 (FIG. 5) extend into and are embedded in the concrete of column 50 when the latter is cast, thereby anchoring the base plate 86 to the bottom 80 of column 50.
  • the base plate 86 As seen in the plane of FIG. 6, the base plate 86 is slightly wider than the column 50.
  • the base plate 86 is substantially longer than the width of column 50, that is, as seen in the direction normal to the plane of FIG. 6, and extends beyond the column 50 on both sides.
  • the base plate 86 is formed with holes to receive the bolts 82, the positions of the said holes corresponding to the positions of the bolts 82, which are outside of the column 50.
  • the column 50 is hoisted by crane into position, over the bolts 82, which are guided through the holes in the base plate 86, whereupon a nut 88 is put onto each bolt 82.
  • Layer 89 is a layer of grouting interposed in well-known manner between the concrete base 81 and the metal base plate 86.
  • the floor 56 and the upper column 60 can be respectively laid and erected as already described with reference to FIG. 5.
  • FIGS. 7 to 12 in that order, illustrate diagrammatically the successive stages of constructing a structure in accordance with the invention.
  • FIG. 7 illustrates the first stage, which is the laying of the concrete floor 81 (FIG. 6) incorporating the bolts 82 in their tubes 83.
  • FIG. 8 illustrates the second stage, which is the erection of the first column 50 (FIGS. 5 & 6) with its female part-joint 20, the joint plate 21 being spaced above the top 55 of column 50.
  • FIG. 9 illustrates the third stage, which is the laying of the floor 56, so that joint plate 21 is flush with the top floor surface 58.
  • FIG. 10 illustrates the fourth stage, which is the erection of the second column 60.
  • FIG. 10 illustrates the top of the second column already fitted with a female anchor 90 which is similar to the female part-joint 20 of FIGS. 1, 2 and 5 and which is anchored in exactly the same way during the precasting of column 60.
  • FIG. 11 illustrates the laying of another floor 91 on top of column 60, just as floor 56 was laid on column 50, whilst FIG. 12 shows the erection of a third column 92 just like column 60. This can be repeated for as many columns and floors as required, subject to stress and strength limitations, of course. It is assumed that the structure will terminate with a floor, not shown, at the top of the structure.
  • FIGS. 5 to 12 that is - show a single "column of columns" 50, 60, 92
  • the intention is that the invention shall be of use where a structure is to have an array of columns, distributed across the structure, at each floor level, so that each column at the bottom shall have one or more other columns directly above it, each adjacent pair of columns, one above the other, being mutually interconnected by a metal joint, through a respective concrete floor at the level where the two columns meet.
  • each and every pair of mutually adjacent columns - that is, any and every two columns that will be one directly on top of the other, at the same time, with the metal connectors already connected up as the concrete sets, then to disconnect the columns after the concrete has hardened, and later to ensure that the same two columns are connected together end-to-end in the same way - in particular, in the same relative angular, or rotational, positions relative to the column axes - in the eventual concrete structure.
  • the part-connectors 20, 31 are marked with unique serial numbers.
  • 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.
  • the bottom end column (such as column 50) will be taken of each line of columns.
  • the next column (such as column 60) will be taken of each line of columns.
  • the third column (such as column 92) will be taken of each line of columns, and so on.
  • FIGS. 13 and 15 illustrate an arrangement of apparatus for casting the three columns 50, 60 and 92, and a fourth column 93, in a line, already interconnected by three connectors 20, 31, as described above and as shown.
  • the apparatus comprises several identical deck units 100 arranged side-by-side in a line as shown, with infills 102a to 102f arranged between certain adjacent deck units 100 as shown to accommodate required variations in the lengths of the columns 50, 60, 92 and 93.
  • FIG. 14 illustrates a slightly different arrangement of deck units 100 and one infill 102g, for making the bottom most column 50 a different length if required.
  • the apparatus comprises (FIG. 13) walers, or waling members 104, supported by the deck units 100 when casting the columns.
  • the apparatus also (FIG. 13) comprises adjustable side shutters 106.
  • Longitudinally extending timber infill 110 (FIGS. 13 and 15) is used where necessary, for example, with columns 92 and 93, to make them smaller in width than the lower columns 50, 60.
  • the stop-ends 111, 113 and the parts 115, 117 have to be replaced after each casting operation. That is, a fresh set is required for each line of columns.
  • Back-to-back pairs of rolled-steel-channels 112 are arranged as shown in FIG. 15, to provide structural rigidity.

  • all the sockets 200 are aligned along the tops of the columns, so that the positions of the sockets 200 can be used later as references in order to ensure that the columns in each line are reconnected, at the time of erecting the concrete structure, in the same angular relationship or rotational position.
  • FIGS. 24 and 25 show the rebars 204, 206 and 208 in full lines, it will be appreciated that the rebars are actually embedded in the concrete, out of sight. Indeed, whilst rebars 204 and 206 are embedded at a relatively shallow angle, so as to be relatively near the surface 210 of the concrete column, the rebar 208 is relatively deeply embedded, so as to distribute the load through the thickness of the column when the column is lifted by the ringbolt 202.

  • the deck units 112 After the columns have hardened, or set, one or other (but not all simultaneously) of the deck units 112 can be lowered, that is, the upper base 120 can be lowered, after the side panels 116, 118 have been "struck", or opened out, so that straps (not shown) can be passed around the column, where the upper base 120 has been lowered, and the straps can be hung from the hooks 198 of the "A"-frames 190.
  • each column can then be rotated about its axis, supported by the straps from the "A"-frames 190, through 45°, so as to disconnect the column from the remainder of the line of columns.
  • each column can be transported - by crane, fork-lift truck or whatever - to a storage site, where each column is stored until required for use.
  • each column it is preferred for each column to be stored in an individually recorded location so that the right column can be quickly retrieved when wanted. 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.
  • One is not limited to casting only one column at a time.
  • the only limitation is that any column being cast is already connected, at the time of casting, to the column which will be immediately below it in the structure, so that proper vertical alignment of the columns can be ensured.
