Definitions

This invention relates to devices for connecting together a supporting layer and a supported layer, separated by continuous insulation or by an air chamber, in infill panels, in accordance with the pre-characterising part of the respective independent claims.
the known support device which passes through the entire thickness of the insulation to rigidly connect the outer layer to the inner layer only at one point, requires the provision of a plurality of "lacing" members in the form of retention elements inserted into the casting to prevent the two layers separating from each other while enabling them to slide to a limited extent due to temperature variation.
the central connection device and the perimetral retention devices have numerous drawbacks.
the first is that relating to heat transmission.
the central device because of the dimensions of the central device and the fact that it passes totally through the panel (ie the supporting, supported and intermediate layers), it creates a thermal bridge which generally considerably reduces the thermal insulation characteristics of the panel.
the retention devices also cause further by no means negligible heat dispersion.
connection system relates to the fact that, depending on the thickness of the supported and supporting layers and of the insulating layer, support and retention devices constructed and sized for the purpose must be used. It is therefore necessary to produce support and retention devices of different dimensions to satisfy design specifications. This inevitable affects the order time and involves the need to hold in store devices dimensioned for a vast range of thicknesses of the supporting, supported and insulating layers.
An object of this invention is to provide a system for connecting the two panel layers together which reduces heat dispersion to a minimum and uses support and retention devices of the same dimensions for any type of panel, ie which are designed for forming panels in which the supported layer, the supporting layer and the insulation of air chamber are of variable thickness.
the connection system comprises a retention device allowing unidirectional movement plus retention devices able to withstand a considerable weight during removal from moulds and, whatever the insulation thickness, to always allow a high degree of movement between the two layers (ie movements of the order of 2 cm, which are normal for the temperature difference between the outside and inside in panels of more than 10 metres in height), so as to drastically reduce the number of retention devices compared with the known art, but without any loss in functionality.
connection system consisting of a support device which can also become a unidirectional sliding device, and by retention devices in accordance with the characterising part of the independent claims.
Figures 1-4 show a prefabricated infill panel comprising a supported outer layer 1, a supporting inner layer 2, and an insulating intermediate layer 3.
the panel layers are separated by continuous insulation or a thermal cut-off and are constructed of usual materials for this purpose, such as concrete or other similar material.
the insulating layer is constructed for example of a polystyrene or polyurethane insulating material, or is in the form of a ventilated air chamber or a combination of insulation and an air chamber.
the supporting layer 2 can also comprise a lightening insert 2A, for example polystyrene.
the panel comprises fixed support devices ( Figures 3 and 5A-C), support devices partly slidable unidirectionally ( Figures 4, 6, 7A, 7B), and retention devices 6 ( Figures 8, 9).
the fixed support devices 4 comprise a substantially pin-shaped body 8 ( Figures 5B, 5C), for example a 40 mm diameter rod of galvanized or stainless steel.
pin means an elongate body with a cross-section of any polygonal shape (circular in the example).
the pin-shaped body 8 comprises a recessed annular portion 7 ( Figures 5B, 5C) for improving the anchoring of the body within the panel.
a T-shaped (in front view) fixing head 9 of greater width L than the pin diameter D and joined lowerly to the pin body 8.
the head 9, which has a greater surface area than the body of the pin, performs simultaneously the function of distributing the weight of the outer layer over a greater metal surface and of anchoring the device to the suspended layer.
a concrete reinforcement element 10 which is in the form of a spring in the example ( Figures 3, 4, 6), can be secured to the pin body 8.
this element rests against a disc 11 ( Figure 6) which before the supporting layer is cast can slide along the body of the fixed pin and abut against the inner wall 3A of a pocket 3B provided in the insulating material.
that portion T ( Figure 6) of the body 8 lying between the disc 11 and the end 8A must be totally embedded in the concrete.
a part of the insulating layer is removed in order to form the pockets 3B (as shown in Figures 3 and 4). In this manner, the pin always has a fixed nominal loading capacity, independently of the thickness of the insulating layer.
the pin does not totally pass through either the supported panel 1 or the supporting panel 2, but penetrates into and engages only a distance M of the thickness S1 of the supported panel and in addition has an insulating disc at its front. In this manner the pin reduces to a minimum the "thermal bridge" between the outside and inside of the construction element, to ensure a more effective thermal insulation the known devices.
the support device with unidirectional sliding 5 comprises a body 8 identical to that of the aforedescribed device 4, the head 9 being however inserted into a rectilinear guide 12 having a C-shaped profile to engage the head 9 of the pin, so that when installed the pin is able to undergo a longitudinal movement along the guide, but not a transverse movement relative to the guide.
the supported layer can freely expand longitudinally, without any deformation of the entire panel due to prevented expansion, and which remains always supported by the support devices.
the supported panel can be connected for example by providing two fixed connection pins 4, which carry all the weight of the supported layer in two central positions indicated by the arrows C, and two unidirectional sliding pins 5 in two more extreme positions, indicated by the arrows E, but lying on the same longitudinal line L on which the fixed pins are provided.
the retention devices 6 comprise substantially a flexible cable 13, for example of 4 mm diameter stainless steel, bent to form an eyelet 13' and closed for this purpose by a ring or splice 14.
a central portion of the cable is housed in a plastic tube 15.
This tube is pointed at one end, and at its other end comprises a collar 15A acting as a stop for a cylindrical spacer 16 mounted on the tube and constructed of a yieldable and easily cut material, such as polystyrene.
the ends of the cable 13 could also be untwisted (as in Figure 9).
the spacer 16, of previously adjustable depth, enables the device to be accurately positioned relative to the position of the insulation.
the use of a stainless steel cable instead of a stainless steel rod offers a much higher resistance to traction and does not present the problem of fatigue due to the daily temperature cycles, so allowing larger displacement of the supported layer relative to the supporting layer.
the number of retention devices required is much reduced, with considerable saving both in working time and in material cost.
the smaller number of retention devices results in reduced heat dispersion.
the retention devices are of fixed dimensions, and hence independent of the insulation thickness. In this respect, the dimensions of the spacer 16 can be modified if the thicknesses of the layers 1, 2, 3 makes it necessary.
connection system formed by the fixed support devices 4, the sliding support devices 5 and the retention devices 6, according to the invention panels can be formed which do not deform outwards, and offer high insulation and/or ventilation, with thermal bridges absent.
the same support and retention devices 6 can also be used on panels of different supported layer, supporting layer and insulating layer thicknesses.
connection devices 4 and 5 and the retention devices 6, according to the invention could also be used in combination with retention devices or support devices of the known art respectively.
the aforedescribed embodiment is provided by way of non-limiting example and that numerous modifications are possible all falling within the same inventive concept, for example the form of the head 9 or of the anchoring end 7 could be different from that illustrated, and the spring 10 could be replaced by other reinforcement elements conventional to the expert of the art, for example one or more logs extending from the body 8.
the head 9 instead of in the guide 12 the head 9 could be inserted in a rectilinear element of yieldable material, for example a polystyrene parallelepiped having substantially the same dimensions as the guide 12.
the cable 13 could be replaced by another conventional element suitable for the purpose, for example flexible braiding.
