Definitions
- This invention relates to modular building components of pre-cast concrete construction such as are disclosed in my prior U.S. Patent 5,081,805, PRECAST CONCRETE BUILDING UNITS AND METHOD OF MANUFACTURE THEREOF, issued January 21, 1992.
- My prior patent discloses a free standing pre-cast concrete building unit of u-shaped cross-section with a generally plain top section or web from opposite edges of which extend a pair of spaced generally parallel flanges or leg sections.
- the bases of the legs are provided with complementary male and/or female members to provide interlocking shear keys when two identical units are assembled in leg to leg inverted relationship to complete top and bottom halves or sides of a room.
- the outside top edges of each unit are formed with complementary alternating tabs and voids of rectangular configurations to provide interlocking of the adjoining edges of identical units when placed in diagonally adjacent top to top inverted relationship.
- first aspects of the present invention provide a joint for installation between building components as defined in claims l or 3.
- Such joints present a unique way of joining the units in stacked form to provide a structural assembly of the units which can completely withstand minor earthquakes or hurricanes and minimize dislocation or damage to the structure in the case of serious earthquakes.
- This concept protects the fixtures and contents of the units as well as the occupants and the integrity of the units themselves.
- the units are connected together in a manner that will provide attachment structures between the units that yield before the stresses on the unit reach a level that would destroy the integrity of the primary structural components.
- the units may be mounted on rectangular rubber pads which absorb the low dynamic motion caused by earthquakes, the units also being connected by high strength bolts that are designed to yield prior to the failure point of the concrete components.
- plates are bolted to individual components in recesses formed at their corners.
- the plates have apertures to receive shear bolts between the units and to sandwich a heavy rubber block or pad adhesively secured between the plates.
- the bolts shear, absorbing energy, and then if there is more unexpended energy, the units may further shift laterally with respect to each other on the rubber pads, by deforming the pad.
- Each step absorbs quake energy and takes away from the stresses that otherwise would be directed to the monolithic walls themselves. This minimizes displacement and destruction of the units.
- the connections will progressively fail before any failure of the units themselves.
- An alternative connection between units includes a first crank arrangement which in an earthquake is alignable with the direction of lateral ground movements, and optionally a second crank arrangement carried by the first which converts further lateral ground movements into vertical movement of the unit.
- Such an earthquake attenuation system is automatically reloaded or primed for any following quakes. Unless the quake exceeds the limits of the attenuator device, the attenuator components bring the building components back to the original pre-quake positions without the necessity of a crane to restack the components together as in many prior cases. In addition, it is not necessary to repair or change parts each time the quake occurs.
- the floor slabs and walls are fabricated to include a sandwiched layer of low density (e.g. foamed polystyrene) or insulation material usually from two to six inches (50-100 mm) thick.
- low density e.g. foamed polystyrene
- insulation material usually from two to six inches (50-100 mm) thick.
- the units may be fabricated thicker, achieving greater rigidity and strength. Lighter units also reduce the building inertia, in turn reducing earthquake imposed forces.
- the slabs of polystyrene foam have spaced openings of about five inches (13 mm) diameter generally on two foot (0.6 m) centres which are subsequently filled with concrete to form keys tying the two reinforced layers of concrete together.
- Appropriate concrete reinforcing bars pass through these openings and are tied into reinforcing grids in each of the lateral concrete slabs.
- the openings in the polystyrene are provided with smooth rounded edges to facilitate the flow of concrete through the polystyrene foam and thereby connecting the outer layers of the slab to each other.
- the resultant product is a unitary unit with integral insulation with the opposed spaced concrete slabs keyed together with reinforcing pins that are surrounded with up to 3 inches (100 mm) of concrete to form a wall structure.
- insulated, lighter, and more rigid floor and ceiling slabs are obtained by incorporation of spaced, parallel polystyrene cylinders. These may be supported during moulding on cut and bent ends of wire mesh reinforcing material incorporated into the slab above and below the cylinders. In between the cylinders, the solid concrete is in the form of I-beam cross sections. Typically, the polystyrene provides sound deadening to the floor and ceiling portions of the resulting half unit and additionally makes the resulting unit much lighter without any loss of strength.
- the polystyrene cylinders are suspended in the concrete generally about two inches (50 mm) from the top and bottom surfaces of the slab.
- the resultant slab is lighter than prior slabs, the I beam cross sectional configuration strengthens the capability to withstand stress and lessens the size of cranes needed for the erection job. Also, because of both the lightness and stiffness of the slabs one can span longer distances beyond the usual limits.
- An additional aspecr of the system provided according to the present invention is the joining of multiple units together or connecting them to other building components by means of extended steel reinforcement in the form of loops facilitating the addition/connection of other concrete elements, advantageously without the appearance of any construction joints, simulating poured in place concrete. This minimizes a major deficiency in pre-cast concrete construction, that of visible connections of units.

- Fig. 40 is a perspective view from below of a unit for use with the columns of Fig. 39;
- Fig. 41 is a perspective view from below of two units as in Fig. 36 secured together side-by-side.
- FIG. 1 shows reinforcing rods and a polystyrene insert prior to forming a wall slab.
- the unit is generally referred to as 2.
- the outside wall forms at 4 and 6 are spaced, depending upon the thickness of the final wall desired, usually two to three inches (50- 75 mm) from the respective reinforcing bar grids 8 and 10.
- a four inch (100 mm) slab of polystyrene foam 12 has openings 14 formed therein with the edges 16 thereof rounded off as shown in Figs. 4 and 5 in order to facilitate the flow of liquid concrete as the unit is formed.
- Reinforcing bars 18 pass through each of the openings 14 and are appropriately tied into the respective reinforcing grids 8 and 10 of the lateral panels as shown at 20 in Figs. 2, 3, and 4.
- the openings are generally located on two foot (0.6m) centres and are generally about five inches to seven inches (130-180 mm) in diameter.
- Fig. 4 shows the cross section of the wall with the forms 4 and 6 in place as the concrete 24 is poured and showing the vertical reinforcing bars 22 crossing the horizontal bars 26 with the bars 18 connecting the grids 8 and 10 through the openings 14 in the polystyrene slab 12 which are now filled with concrete, connecting two sections of concrete together forming the unified wall.
- Liquified concrete 24 is poured in as shown in Fig. 3.
- Fig. 5 shows a cross section of the completed wall with the forms 4 and 6 removed and the two layers 28 and 29 of the concrete connected with concrete fingers 30 extending through the openings 14.
- the resulting wall is very strong, rigid and lighter to move because of the foamed polystyrene which also serves as heat and sound insulation for the walls between the units.
- FIG. 6 forms 31 and 32 for a ceiling or floor panel 54 are shown with upper and lower reinforcing bar grids 33 and 35 cut and the resulting bar ends turned inwardly and outwardly as indicated at 40, 42, 44 and 46.
- the inwardly turned ends such as 40, 46 penetrate into the sections of polystyrene 48, 50 and 52 respectively so as to hold them in place during the concrete pour.
- Outwardly turned ends such as 42, 44 may optionally be used to position the grids 33, 35 relative to the forms 31, 32.
- the assembled foam unit is shown ready for pouring in Figs. 7 - 9.
- Fig. 8 shows an end view of the polystyrene units 48, 50, and 52 in place connected to the reinforcing bar grids 34 and 36 in Fig. 7.
- Fig. 9 shows a cross section through lines 9-9 of Fig. 8. After the pour, the same view in Fig. 8 will appear as in Fig. 10 with the completed slab 54. It is noted that polystyrene will serve to both deaden noise, lighten the resulting unit 54, and also that much of the concrete is in the form of parallel I beam units resulting in greater strength for unit weight. Instead of the polystyrene cylinders running transversely as shown in Fig. 8, they could run normal to the plane of the page as shown. In a further alternative, one of the cut reinforcing bar grids could be turned 90° in its own plane, from the position illustrated in Figs. 6 and 7. The cuts in adjacent bars can be staggered. Further uncut bars can be provided in the grid, parallel to and between the polystyrene cylinders.
- FIG. 11 A reinforcing bar grid 60 for a semi-room unit is shown in Fig. 11, the bars being crisscrossed for wall grids 68 and 70 and base grid 66 and looped at their ends 72 and 74 respectively.
- the loops 72 and 74 all extend from the edges of the base 82 and walls 78 and 80 of the poured unit 76 as shown in Fig. 12 to facilitate joining the units together as indicated in Fig. 13 where two units 76A and 76B are being joined together.
- Fig. 14 shows a form surrounding abutted wall edges at one side of the units, the loops 72 overlapping within the form as shown for the exposed wall edges.
- Fig. 15 is a cross-section of the form taken along lines 15-15 of Fig. 14.
- units 76A and 76B can be joined utilizing apertures 86 made by placing PVC cylinders in the form when units 76 are poured. These are utilized for tying the joining forms together as described below.
- the two units 76A and 76B are joined by overlapping their looped edges 72 and 74 as shown in Figs. 14 and 15 with the form 90 comprising sides 96 and 98 used to connect the two looped edges together.
- Bolts are passed through respective holes 97 and 99 in the form walls 96 and 98 and through PVC tubes 86 in the respective sections 76A and 76B for holding the form 90 in place.
- the ends 100 and 102 of the form 90 are tilted so as to slope downwardly and inwardly as shown in Figs. 13, 15 and 16.
- the form 90 has movable plates 106 and 107 at the ends to facilitate pouring the concrete.
- electrical outlets 84 and conduits 85 may be placed (Fig. 13).
- the units may be joined in various formats such as shown in Fig. 17 where units 76A and 76B are joined at the section 94 as shown. Various other configurations may readily be accomplished.
- Figures 18 through 23 illustrate a mechanism for securing completed units together in structures to minimize or prevent harm to the structural units, their contents, and occupants in earthquakes and hurricanes.
- an upper unit 120 is joined to a lower unit 124.
- the top unit 120 has at its lower corner a recess 122 as shown with a corresponding recess 126 in an upper corner of the lower unit 124.
- the unit 124 has reinforcing mesh 128 with additional rods 130, 132, and 133.
- the reinforcing rods 130, 132, and 133 are welded to a plate 162 in wall 124 and corresponding reinforcing bars 130', 132', and 133' in the top unit 120 are welded to a plate 160.
- Metallic U shaped members 140 and 142 respectively are bolted to plates 136 and 138 by bolts 134 or the bolts 134 may be sunk directly into the concrete of units 120 and 124. Normally the plates 136 and 138 respectively are welded to plates 160 and 162 respectively.
- the base 150 of the part 140 has arms 152 and 154 which correspond to parts 152' and 154' in the member 142.
- the parts 150 and 150' are bolted together by high tension bolts 144 which pass through apertures in the flanges 156, 156' and 158, 158' and nuts 145 as best shown in Figs. 20 and 21.
- a heavy duty Neoprene rubber block 146 In between the members 150 and 151' is a heavy duty Neoprene rubber block 146 which is compressed slightly as the bolts 144 are tightened, drawing flanges 156, 156' and 158, 158' towards each other.
- Fig. 20 is an enlarged perspective view of the unit.
- Fig. 23 is a view showing it together with the extra reinforcing rods 130, 132, 133, 130', 132,' 133' welded to the base plates 160, 162.
- the units 120 and 124 following a quake which reaches a magnitude severe enough to shear the bolts 144, the units 120 and 124 have shifted laterally with respect to each other. The movement is resisted by deformation of the heavy duty Neoprene rubber pad 146.
- Quake energy is absorbed in shearing the bolts 144 and deforming the block 146, as well as in sliding friction between the units 120, 124.
- the integrity of the units 120 and 124 is preserved as the connections are designed to deform and absorb energy at forces below those which would destroy the units 120, 124.
- the bolts 144 replaced and, if necessary, new Neoprene blocks inserted and glued between the respective plates 150 and 151'.
- the units can be interconnected by rigid links or stops providing a suitable degree of lost motion: if a very severe earthquake occurs, the links or stops will prevent vertically stacked units from toppling, perhaps at the expense of some structural damage to the units themselves.
- FIG. 24 through 29 Another earthquake energy absorbing device is shown in Figs. 24 through 29.
- An upper unit 170 is joined to a lower unit 174 the upper unit 170 corner having a recess 172 and the lower unit 174 corner having a recess 176 to accommodate the device.
- Reinforcing bars 178, 180 and 182 shown in phantom in the wall section 170 are welded to plate 216 to which the device is mounted.
- a similar plate 217 is shown on bottom section 174.
- a shaft 218 having a bumper stop 220 mounted thereon and a coil spring 222 secured between bumper 220 and a plate 190 pivotally mounted thereon.
- the plate 190 has an aperture 192 therein in which a shaft 194 is rigidly secured. At its lower end the shaft 194 is attached to a fixture 196 through which a cross bar 198 is rotatably received.
- the bar 198 is secured in recesses 204 and 206 in vertically oriented wheels 200 and 202 respectively which in turn are rotably mounted on the horizontal ends 212 and 214 respectively of upright pins 208 and 210 which are secured to a plate 211 which is pivotally mounted on a shaft 215 and secured by a nut 213. At its base shaft 215 is welded to the mounting plate 217.
- the device serves to initially orient the crank or eccentric formed by plate 190 and shaft 194 in the direction of lateral movement of the quake thereby absorbing energy as it turns, and simultaneously orienting the crossbar 198 transversely of the direction of quake movement.
- Such initial orientation can be seen by comparing Figs. 26 and 27, wherein the direction of quake movement is normal to the page.
- the spring 222 in Fig. 28 is compressed as the shaft 218 is driven downwardly. Quake energy is absorbed by such compression and also by contact of the spring 222 and plate 190 with the bumper stop 220. Frictional or other damping may be provided against movement of plate 190 along shaft 218 and against rotation of plates 190, 211 about shafts 218, 211 respectively.
- the eccentric cross bar 198 has been rotated to a higher position in Fig. 28 and then downwardly in Fig. 29.
- Figs. 30-34 show an improved, high strength joint configuration for use in uniting abutted corners of my U- shaped building units.
- the floor slab 302 of a unit 304 is connected to a wall slab 306 of the unit 304 by a series of lands 308 extending half way across the thickness of wall slab 306.
- Between the lands 308 are a series of indentations 310 which extend across the whole thickness of the wall slab 306 to leave small through gaps 312 between the wall and floor slabs.
- the lands and indentations are produced by incorporating suitable inserts and packing pieces into the moulding form.
- Reinforcing bars 314 are arranged to run from the floor slab through the lands 308 and into the wall slab 306 as indicated by dotted lines 314' in Fig. 30. Further reinforcing bars 316 are arranged to run from the floor slab 302 out into the indentations, forming exposed loops 318, and back into the wall slab 306. The encased portions of the bars 316 are indicated by dotted lines 316' in Fig. 1.
- pairs of units are assembled corner-to-corner, a given unit being inverted with respect to its neighbour, the vertical faces of the lands 318 of neighbouring units being abutted.
- the indentations 310 of the assembled units thereby co-operate to define void spaces 320, within which the reinforcement loops 318 of the respective units overlap.
- a locking bar 322 is then threaded through the overlapping loops 318 to form an interlocking reinforcement network.
- Wet concrete can then be poured and compacted through the uppermost gaps 312 to fill the void spaces 320.
- the lower gaps 312 can be used to check that the void spaces are being properly filled, after which they are plugged, for example by lengths of timber secured in the angle between the wall and ceiling slabs.
- a very strong unitary structure is obtained, having an effectively continuous tensile reinforcement network formed by the crossed and interlinked bars 316.
- the indentations 310 should be made to occupy as large a proportion as possible of the total depth d (Fig. 30) of the unit.
- the total depth of the lands 318 should therefore be minimised, providing just sufficient strength to hold the wall and floor slabs of the unit together during moulding, transportation and final placement.
- it can be braced by an internal framework 324, Fig. 35 of, for example, steel tubing or timber.
- a strap 326 may be secured around the unit, between the free ends of the wall slabs 306.
- plastics tubes 328 may be moulded into the unit 304 to form through holes in the wall slabs aligned along an axis which passes approximately through the centre of gravity of the unit.
- a support bar 330 can be inserted through the tubes 328 with its ends projecting outwardly of the wall slabs 306, to which ends a sling 332 and spacer beam 334 can be attached, for suspending the entire assembly from a crane hook 336.
- a typical unit weighing several tonnes can be oriented and guided into place by a single workman, the unit 304 being rotated as necessary about the axis of the crane wire 338 and the axis of the support bar 330.
- Figs. 36-41 show a modified form of my building unit for use in structures having vertical support columns 340, for example high-rise buildings or multi-storey car parks.
- Unit 342 shown in Fig. 36 like the building unit ⁇ disclosed in my US Patent No. 5081805, is of generally U-shaped cross-section but has wall slabs 344 of comparatively reduced height, for example about 0.6 m. These act as stiffening flanges for a floor slab 346.
- the unit 342 has cut-outs 348 made by appropriate inserts in the forming mould. These cut-outs co-operate with ledges 350 provided on the support columns to support the unit at a desired height.
- Tongues 352 between the cut-outs at opposite ends of the units project between pairs of the support columns 340, the tongues of adjacent units abutting to form a continuous floor surface. Corners 354 of the unit 346 rest on the ledges 350 to which they are secured, for example by studs 356 and nuts 358.
- Fig. 40 shows a unit 360 modified for use with columns interconnected by crossbeams 362, Fig. 39.
- One end of the projecting tongue 364 is continued to lie flush with the outer edge of wall slab 366.
- Pairs of such units 360 are arranged side-by-side in mirror image fashion with their walls 366 abutted and their projecting tongues 364 resting on the cross beams 362, once again forming a continuous floor surface.
- Fig. 41 shows a pair of units 342 like those of Fig. 36, interconnected for support by only four columns 340 instead of six.
- Steel trusses 368 are bolted in place between the wall slabs 344 at the ends of each unit.
- the abutting wall slabs 344 and adjacent ends of the trusses 368 are also bolted together.
- the cut-outs 370 at the outer corners of the interconnected units accommodate the support columns 340, whereas the central cut-outs 372 are plugged by suitable infill.
- three or more units 342 may be interconnected side-by-side in like manner.
- the ledges 350 or other support formations are provided at suitable spacings on the columns 340 (typically 2.5-3.5 m) to give the required floor separations.
- the space between the depending wall slabs 344 can be used to accommodate building services such as electric cables, pipework and ducting. This space can if necessary be screened off from the room space below by a suspended ceiling.
- the system of units and columns shown in Figs. 36- 41 can thus be used to create large open-plan areas.
