Abstract
Description
- The object of this invention is a building structure made of prefabricated elements according to the features of the precharacterising part of
claim 1. - Building structures made of modular prefabricated elements are known. However, they suffer sometimes from various drawbacks such as the following:
- a. the basic elements are encumbrant and difficult to transport;
- b. the number of the basic structural elements and of the accessory elements for assembling them is excessive;
- c. welding on the spot of metal elements is required which implies a low reliability of the weldings and a troublesome work.
- 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.
- The above drawbacks are overcome in the building structure of the present invention in as much as a low number of modular elements (panels) and of assembling elements is used. No welding work is to be made on the spot.
- According to

Special type panels are also provided in which apertures are provided for applying doors and windows thereto.
- On assembling the panels, these are mounted in approached relation to one another and connected each to the adjoining panels by mechanical means which engage the upper channellike profiles of the panels. The panels are anchored to the reinforced concrete slab of the building by means of vertical tie rods the lower ends of which are hooked onto said slab by means of cramps buried into the slab concrete.

- With reference to the drawings 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 bysteel rods 10 perpendicular to one another and to the panel sides; achannellike metal profile 19 built in along the side of each panel which is the top side of the panel when this is installed; achannellike metal profile 9 is built in along each of the panel sides which are the vertical sides when the panel is installed, whichprofile 9 extends from the lower end of the panel up to the level of the bottom of thechannel 19; theabove channels - 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 theinvention channel 19 near each of its ends is provided with twoshoulders 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 ofchannel 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 asecond length 9" equal to about the length of said shorter side and for a third length 9'" equal to about one third of thelength 9" at an angle of about 120 deg, with respect thereto. - At regular distances along each of the two corners between
lengths 9' and 9" of the profile cross-section a series ofopenings 15 are provided for better fastening the profile to the concrete. - Along the side of the profile which in cross-section is the longer side of the rectangle, 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. Along the lower side of panel 5 agroove 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. - When a pair of said panels are installed side by side, a wellhole or shaft is formed between each pair of panels along their adjoining vertical sides which shaft is defined by the
respective channellike profiles 9 of the panels. Additional panels slightly different from the normal one are provided for making the building corners and for bonding or grafting an interior wall onto a peripherical wall. They will be named hereinafter "corner panel" and "T graft panel". One of the vertical edges of the corner panel 23 (fig. 10) is the same as the sides of anormal panel 5 while at the other edge, as shown in Fig. 10, thevertical profile 9 is not, as inpanel 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 anormal panel 5 pertaining to the peripheral wall of the building at right angles with the wall which thecorner panel 23 belongs. The position of themetal channel 19 of the corner panel will be such that the outer surface ofpanel 5 will come flush to the outer surface of the edge ofpanel 23. Whenpanels 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 thechannel 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 aplate 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 theprofiles 9 of the adjoining panels and forming therewith the ducts through whichtie rods 11 are to be led. - The system will now be described for anchoring the panels of the invention to the
foundation slab 1 of the building. Intofoundation slab 1, possibly provided with a grid of reinforcingrods 10, an anchoring clamp is embedded 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 intoduct 12. At the upper level of the foundation slab 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 verticallyelongated 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. Into eachslot 6 the hooked lower end ofvertical 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 theduct 12 to reach near the level of the upper edge of the panel, the upper end of the rod being threaded. At the upper edge of the panels theprofiles 19 of two adjoining panels and the tie rod which extends upwards fromduct 12 formed by the twovertical profiles 9 of said panels are jointed together. The jointing, both in the case of two normal panels and in the case of corner panels and graft panels, is made by means of angled plates of which the horizontal arms engage theshoulders 27 projecting from the vertical inner sides of theprofiles 19 of the respective panels to be joined, and the vertical arms are coupled by means ofbolts 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 anut 18 tightened on the threaded end section oftie rod 11. - In the case of two normal panels (fig. 6) 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 tierod 11 and a short angle plate (fig. 13C) will be fitted into the profile of the other panel. When the two panels are approached to one another the vertical arms 21' and 20' of the two plates will mate each other and be tightened together by means ofbolt 22. This is feasible due to offset oftie rod 11 in as much asbolt 22 andnut 18 do not interfere with one another. When anormal 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. 10 thetie rod 11 included) while anangle plate 24 of the type illustrated of in fig. 14C is used for the corner panel. The vertical arm ofplate 24 extends upwards from one side of the plate and whenpanels angle plate 21.Angle plates bolt 22 andplate 21 is connected to therod 11 by of anut 18. When a normal panel pertaining to an interior wall is to be joined to a pair ofT graft panels 25 pertaining to a peripheral wall, along angle plate 21 will be used for the normal panel and ashort angle plate 20 for one of thegraft panels 25 while for the other graft panel anangle plate 26 will be used having the same length asplates vertical arm 26" at one of its sides in addition to a vertical arm 26' at one of its ends.Plates 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 ofchannel 19. - 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 induct 12 the inlets and outlets of which can be made to extend from said duct through holes of which the duct walls are provided. - In a second embodiment of the invention the system is changed for joining the upper channellike profiles 19 of two adjoining panels to one another.
- According to said embodiment 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 withshoulders 27 reciprocally projecting from the inner sides of the channel for engaging the notches 27' of the appropriate angle plate. In this embodiment all the connecting plates are flat and are fastened on bored and threadedblocks 38 which are welded on the lower surface of the bottom wall ofchannel 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 ahead bolt 40 pass through and be screwed intoblock 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 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 ofprofile 19. As shown in fig. 9A,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 withtie rod 11, is round and the other two 36, 36', coincident each with ablock 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 theupper channel 9 of a normal panel 5' and a shorter arm to be fitted into theupper 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 withtie rod 11 and another 36 is elongated and coincident with ablock 38 welded underneath ofchannel 19 pertaining to panel 5', the other hole 36' being elongated and coincident with ablock 38 welded under theprofile 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. Along the common centerline of the shorter arms around hole 36" is provided coincident withtie rod 11 and twoelongated holes 36, 36' are provided coincident with therespective blocks 38 of the two graft panels 25'. - In all the three cases above described the connecting
plates respective blocks 38 and by a nut tightened on therespective rod 11. - When the building is a multistoried building according to an important aspect of the invention a floor (figs 16 and 17) is built on the upper edges of the ground story panels.
- To this purpose longer 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.
- Together with the corrugated sheet a reinforcement of the
floor slab 30' will be laid which comprises an upper array ofrods 16 and a lower array ofrods 29 the rods of the upper array being interlaced with rods running along the periphery of thefloor slab 30' between the outer and inner planes of the walls; the rods of the lower array having their ends bent at square angles and fitted into theprofiles 19 of the wall panels. Subsequently to applying a horizontal planking on the outer surfaces of the walls over an area corresponding to the thickness of the floor to be built to function as a formwork, a mass of concrete will be cast over the corrugated sheet and into theprofiles 19. Subsequent to the casting of the concrete mass and to the setting thereof an invertedT shape rail 31 will be laid on the top surface of thefloor slab 30' which rail lies on the vertical plane of shape 4 on which the lower ends of tie rod 11' are hooked. At the position where eachtie rod 11 energes fromslab 30' the upright leg ofrail 31 is cut away for a short length to provide a space for a hole 31' through the flange ofrail 31 and for inserting a threadedsleeve 32 flanged at its lower end surrounding hole 31'.Tie rod 11, after passing through hole 31' extends upwards for a short threaded length which engages the inner threading ofsleeve 32 for one half of the length thereof, the remaining length of the sleeve inner threading being engaged by the threaded lower end of anextension 33 oftie rod 11.Extension 33 has a length equal to the height of a building story. - The building roofing is not described herein because is it not within the scope of the invention. It can be of any known type such a platform roof, a pent roof, a gable roof and so on. For anchoring the roof to the
building tie rods
