Definitions

  • the object of this invention is a building structure made of prefabricated elements according to the features of the precharacterising part of claim 1.
  • FR-A-1 565 754 discloses a building wall made of a number of wall panels which are aligned to form a wall. Such panels are provided with a lower and upper structural shapes which are connected together by means of tie rods which extend each along a vertical groove provided at about the vertical mid plane of the wall. Each of said tie rods is adapted but not bound to the panel mass along said groove.
  • USA Patent.2.924.962 to Nettle describes a solid concrete wall construction comprising a plurality of precast panels approached to one another which have each a pair of vertical terminal grooves and a number of vertical parallel vertical ducts; said grooves pertaining to a pair of adjoining panels being empty at their insides except for short keys whereby they are coupled together in cooperation with outer locking lugs.
  • each of the panels is provided along its upper edge with a horizontal channellike metal top profile open upwards and along its vertical sides with a channellike metal side profile such that a duct filled with concrete is defined between the vertical side profiles of a pair of adjoining panels as assembled in the building; said metal profiles both top horizontal and side vertical being unbedded in the concrete panel when this is cast into its form.
  • a normal type panel is provided to be used for the perimetral walls of the building- the building corners being excluded- and for the interior walls (the structure for bonding or grafting the latter to the peripheral walls being excluded) and two types of panels slightly different from the normal panel, of which one type is to be used for the building corners and the other for bonding or grafting an interior wall with a peripheral wall.
  • Special type panels are also provided in which apertures are provided for applying doors and windows thereto.
  • the building structure of this invention comprises as its basic structural element a rectangular prefabricated panel 5 made of reinforced concrete wherein a reinforcement is embedded which may comprise two parallel grids formed by steel rods 10 perpendicular to one another and to the panel sides; a channellike metal profile 19 built in along the side of each panel which is the top side of the panel when this is installed; a channellike metal profile 9 is built in along each of the panel sides which are the vertical sides when the panel is installed, which profile 9 extends from the lower end of the panel up to the level of the bottom of the channel 19; the above channels 19, 9 are embedded into the concrete mass when this is cast into the panel form.
  • a reinforcement which may comprise two parallel grids formed by steel rods 10 perpendicular to one another and to the panel sides; a channellike metal profile 19 built in along the side of each panel which is the top side of the panel when this is installed; a channellike metal profile 9 is built in along each of the panel sides which are the vertical sides when the panel is installed, which profile 9 extends from the lower end of the panel up
  • the horizontal channel 19 is shown in perspective in fig. 8 and in top view and longitudinal cross-section in figs. 8A and 8B. It is made of an upward open C iron sheet profile. According to an important aspect of the invention channel 19 near each of its ends is provided with two shoulders 27 projecting from the opposite vertical sides thereof which shoulders, as specified hereinafter, serve for connecting together two adjoining panels.
  • Vertical channel 9 is an iron sheet profile shown in perspective in Fig. 7B and in cross-section in fig. 7A. It extends downwards to reach the lower edge of the panel and upwards to reach the level of the bottom of channel 19.
  • Channel 9, in cross-section is formed by a rectangle lacking one of its longer sides while each of the shorter sides extend perpendicularly thereto for a length 9' slightly shorter than said shorter side and for a second length 9" equal to about the length of said shorter side and for a third length 9'" equal to about one third of the length 9" at an angle of about 120 deg, with respect thereto.
  • a series of undulating tongues 14 are formed by punching intended for being buried into the concrete mass of the panel for restraining the profile thereto.
  • a groove 7 is provided into which the upright leg of an inverted T iron shape 4 is to be received as explained hereinafter.
  • An indentation 7' will also be provided at the lower end of the vertical channellike profile 9 symmetrical with respect to the symmetry plane thereof for receiving the inverted T shape 4.
  • Panel 5 as described serves for making the walls of the building structure according to the invention and will be called hereinafter, "normal" panel.
  • corner panel 23 (fig. 10) is the same as the sides of a normal panel 5 while at the other edge, as shown in Fig.
  • the vertical profile 9 is not, as in panel 5, symmetrical to the median plane of the panel but lies on a plane perpendicular to the panel along the face border thereof to be joined to the edge of a normal panel 5 pertaining to the peripheral wall of the building at right angles with the wall which the corner panel 23 belongs.
  • the position of the metal channel 19 of the corner panel will be such that the outer surface of panel 5 will come flush to the outer surface of the edge of panel 23.
  • a square prismatic vertical duct 12 is defined by the respective profiles the same as with the case of a pair of normal panels.
  • the T graft panel 25 (fig. 11) is nearly similar to a normal panel 5 except for the fact that a very short end section is lacking of one of the panel upward projections between which the channel 19 is received.
  • the void left by said lacking section added to a similar void of the adjoining panel will provide enough space for fitting thereinto a plate 21 for connecting the interior wall to the peripheral wall.
  • Interior wall E is grafted to the peripheral wall F at the joining of two panels of the latter which panels must be justly of the T graft panel type.
  • any of the three panels as above may be lightened, while preserving its dimensions, by replacing a part of the concrete thickness with a lighter material such as synthetic foam and the like.
  • Special panels not described herein are made with apertures for installing windows and doors in the building walls. Such panels must anyway be provided at their upper edges with a means for connecting them to channels 19 of the adjoining panels and with profiles adapted for mating the profiles 9 of the adjoining panels and forming therewith the ducts through which tie rods 11 are to be led.
  • an anchoring clamp which comprises two symmetrical jaws coupled to one another by bolts 3 (fig. 2), the clamp overall dimensions being such that it can be received into duct 12.
  • an inverted T structural shape 4 is laid down of which the flanges are encompassed by the two jaws of the clamp.
  • a series of vertically elongated slots 6 are provided through the leg of shape 4 at a distance from one another equal to the horizontal size of the panel (when installed) but slightly displaced with respect to the mating plane of two adjoining panels vertical sides.
  • each slot 6 the hooked lower end of vertical tie rod 11 is inserted which rod is thus displaced as the related slot from the mating plane of the two adjoining panels whereby the rod extends vertically within one half of the duct 12 to reach near the level of the upper edge of the panel, the upper end of the rod being threaded.
  • the profiles 19 of two adjoining panels and the tie rod which extends upwards from duct 12 formed by the two vertical profiles 9 of said panels are jointed together.
  • the jointing is made by means of angled plates of which the horizontal arms engage the shoulders 27 projecting from the vertical inner sides of the profiles 19 of the respective panels to be joined, and the vertical arms are coupled by means of bolts 22 to one another.
  • the vertical tie rods extend through a hole of the horizontal arm of one of the plates and is fastened thereon by means of a nut 18 tightened on the threaded end section of tie rod 11.
  • a long angle plate 21 (fig. 12) is used which will be fitted into the profile 19 of that panel whose shoulders are nearer to tie rod 11 and a short angle plate (fig. 13C) will be fitted into the profile of the other panel.
  • a short angle plate (fig. 13C) will be fitted into the profile of the other panel.
  • the vertical arms 21' and 20' of the two plates will mate each other and be tightened together by means of bolt 22. This is feasible due to offset of tie rod 11 in as much as bolt 22 and nut 18 do not interfere with one another.
  • a normal panel 5 is to be joined to a corner panel 23 (fig. 10) a long plate similar to the preceding case is used for the normal panel (within whose periphery as shown in fig.
  • angle plate 24 of the type illustrated of in fig. 14C is used for the corner panel.
  • the vertical arm of plate 24 extends upwards from one side of the plate and when panels 5 and 23 are brought to mate together, said arm mates the vertical arm of angle plate 21.
  • Angle plates 21 and 24 are connected by means of a bolt 22 and plate 21 is connected to the rod 11 by of a nut 18.
  • a long angle plate 21 will be used for the normal panel and a short angle plate 20 for one of the graft panels 25 while for the other graft panel an angle plate 26 will be used having the same length as plates 21 and 24 but being provided with a vertical arm 26" at one of its sides in addition to a vertical arm 26' at one of its ends. Plates 21,20,24,26 will be connected together and to tie rod 11 as in the two preceding cases.
  • All the above angle plates are provided at each side of their horizontal arm with a notch 27' symmetrical to one another adapted for engaging the reciprocally facing shoulders 27 projecting from the two vertical walls of channel 19.
  • duct 12 Prior to applying the above angle plates, duct 12 will be filled with cement mortar. Prior to casting the mortar, any pipes or cables can be included in duct 12 the inlets and outlets of which can be made to extend from said duct through holes of which the duct walls are provided.
  • the system is changed for joining the upper channellike profiles 19 of two adjoining panels to one another.
  • each of the upper profiles 19 of a normal panel, corner panel and graft panel which in this embodiment will be respectively identified by reference numbers 5', 23', 25' is not provided near each of its ends with shoulders 27 reciprocally projecting from the inner sides of the channel for engaging the notches 27' of the appropriate angle plate.
  • all the connecting plates are flat and are fastened on bored and threaded blocks 38 which are welded on the lower surface of the bottom wall of channel 19 and thus buried into the panel concrete, when this is cast into the panel form. Said bottom wall is drilled at the location of each block for letting a head bolt 40 pass through and be screwed into block 38.
  • the connecting plates in the three cases of continuous wall, building corner and interior wall grafted to a peripheral wall are shown in plan view in figs. 9A, 10A, 11A respectively and are respectively identified by reference numbers 35, 37 and 39.
  • Plate 35 is shown in cross-section by figs. 5A and 6A. it has the shape of a rectangle of which one side is slightly shorter than the width of the bottom wall of profile 19.
  • plate 35 is disposed symmetrical with respect to the mating plane of the two panels to be joined together and has three holes along the centerline of the plate one of which, coincident with tie rod 11, is round and the other two 36, 36', coincident each with a block 38, are elongated in the direction of said centerline.
  • Plate 37 as shown in fig. 10A, has an "L" shape in plan view with a longer arm to be fitted into the upper channel 9 of a normal panel 5' and a shorter arm to be fitted into the upper channel 19 of a corner panel 23'.
  • Plate 37 is provided with two holes along the centerline of the longer arm, one of which is round and coincident with tie rod 11 and another 36 is elongated and coincident with a block 38 welded underneath of channel 19 pertaining to panel 5', the other hole 36' being elongated and coincident with a block 38 welded under the profile 19 pertaining panel 23'.
  • Plate 39 as shown in fig. 11A has a T shape in plan view with two equal arms shorter than the third arm perpendicular thereto.
  • the two shorter arms are to be fitted into respective channels 19 of two adjoining graft panels 25' of a peripheral wall and the longer arm is to be fitted into the upper channel of a normal panel 5' of an interior wall.
  • a round hole 36" is provided coincident with tie rod 11 and two elongated holes 36, 36' are provided coincident with the respective blocks 38 of the two graft panels 25'.
  • a floor (figs 16 and 17) is built on the upper edges of the ground story panels.
  • tie rods 11' are to be used for building the ground story instead of tie rods 11 as used for a single-storied building.
  • Tie rod 11' in fact must be long enough for surpassing the floor thickness in addition to the height of the ground story panels.
  • the upper section of tie rod 11' will be threaded for its length passing through the floor and, in addition, for a short length from the under surface of the floor downwards.
  • the floor will be made by laying a corrugated sheet 30-preferably with corrugations of trapezoidal cross-section-from one to the other of two parallel walls of the room to be covered by the floor; in case of a rectangular room the sheet corrugations will run parallel to the shorter sides of the rectangle.
  • the peripheral edges of sheet 30 will extend to rest only on the upwardly extending inner projections along the upper edges of the wall panels so that the channellike profiles 19 of the panels will be left uncovered.
  • Corrugated sheet 30 as set forth hereinafter, is intended for functioning as a form for casting the concrete mass of the floor and for cooperating therewith.
  • the downward facing furrows of the sheet will be closed at their ends by trapezoidal plates welded along their edges to the furrow profile for preventing any cement mortar from falling down when casting it over the corrugated sheet.
