Description
"Machine to carry out a self-bearing reticulated panel"
* * * *
DESCRIPTION
The present invention relates to a machine to carry out a self-bearing reticulated panel.
WO-96/31314 describes a system to carry out building panels comprising means for forming structural blocks of foamy material as polystyrene, means for cutting said blocks, means to carry out reticulated reinforcement structures consisting of variously braided rods, means for coupling said reticulated structures with the structural blocks, and means for attaching cross members to the reticulation so as to form a three- dimensionally reinforced panel.
US-4614013 describes a method for forming structural panels reinforced with a reticulation consisting of variously braided steel rods passing the panel. First, said method provides to carry out the reinforcement reticulation consisting of rectilinear rods connected by "zigzag" rods adapted to define a three-dimensional reinforcement within the panel, thereafter the placement of said reticulation within a suitable seat adapted to allow pouring the foamy material of the panel still in a flowable state. Once the filling step of the seat, which usually has a shape adapted to obtain a parallelepiped panel, has ended, the foamy material cools down, expands thereby integrally encompassing the reticulation crossing it.
This method to carry out reinforced panels, also found in U.S. patents US-3305991, US-3555131 and US-3838241, has the drawback of having to cast the foamy material in a flowable state, that is, at high temperatures, within a clearly defined mold with the finished reticulation inserted therein. The interactions that generate between panel and reticulation subsequent to the quick cooling of the foaming material are difficult to foresee and disadvantageous structural tensions could therefore generate, besides breaks at the welding points. Moreover, the reinforcement reticulation must be
completed prior to the coupling with the panel, by electro-welding, with a consequent poor geometrical accuracy of the reticulation meshes. Accordingly, the mechanical resistance properties, for example to seismic phenomena, are very limited. Very resistant and heavy foamy materials should therefore be used in order to obviate these drawbacks, thereby impairing the transportability of the finished reinforced panel.
The object of the present invention is to provide a machine to carry out a panel of foamy material adapted to be coupled at the solid state with a reinforcement reticulation in a simple, dimensionally accurate manner and with limited costs.
A further object of the present invention is to provide a process to carry out a simple, repeatable self-bearing reticulated panel and which should ensure easy transportability thereof, preserving the bearing properties of the panel.
Yet another object of the present invention is to provide an anti- seismic light self-bearing reticulated panel and with high heat insulation capabilities.
According to the invention, such object is achieved with a machine to carry out through slits in a parallelepiped panel in a solidified foamy material, characterized in that it comprises a base frame supporting a horizontal guide along which two motor driven trolleys move, to each trolley a vertical plate supporting a plurality of rods for reinforced concrete being fixed, between the two plates being provided a vertical upright suitable to sustain the panel to pierce with said rods for reinforced concrete.
According to the invention, such a further object is achieved with a process to carry out a self-bearing reticulated panel comprising a panel in solidified foamy material and a reticulated reinforcement structure with transversal rods crossing said panel, characterized in that it provides the carrying out of the solid panel, the carrying out of through slits passing said solid panel with form and dimension substantially corresponding to said
transversal rods, the assembly of said solid panel with said reticulated structure occurring lodging said transversal rods in said slits.
According to the invention, such yet further object is achieved with a self-bearing reticulated panel comprising a panel in solidified foamy material and a reticulated reinforcement structure with transversal rods crossing said panel, characterized in that said panel provides through slits suitable to lodge said transversal rods.
These and other features of the present invention will appear more clearly from the following detailed description of a practical embodiment thereof, made by way of a non-limiting example with reference to the annexed drawings, wherein:
figure 1 shows a front view of a machine according to the present invention in an open quiescent position;
figure 2 shows a front view of the machine of figure 4 in closed operating position;
figure 3 shows a side view of the machine;
figure 4 shows a perspective view of a block with formed slits;
figure 5 shows a top plan view of the block of figure 4;
figure 6 shows a side view of the block of figure 4;
figure 7 shows a front perspective view with side split of a mounted self-bearing reinforced panel;
figure 8 shows a rear perspective view of the panel of figure 7;
figure 9 shows a top plan view of the panel of figure 7;
figure 10 shows a side partially sectional view of the panel of figure 7; figure 11 shows an enlarged view of rod A of figure 10.
A machine 1 to carry out slits 2 in a parallelepiped panel 3 in a solidified foamy material, for example polystyrene, comprises a base frame 4 supporting a horizontal guide 5 along which two motor 16 driven trolleys 6 move.
A vertical plate 7 supporting a series of rods for reinforced concrete 8
of triangular shape is fixed to each trolley 6 as shown in figure 1. A vertical upright 14 is provided between the two plates 7, external to the space occupied by the rods for reinforced concrete 8, suitable to sustain the polystyrene panel 3 to be pierced with said rods 8 that can be warmed by means of electric supply means, for example wires 91 run through by current regulated by transformer and thermostat 92.
A three-dimensional reinforcement reticulation 10 (figures 7-10) suitable to be associated to panel 3 with plaster 32 is provided with two end reticulations 11 with substantially flat meshes 12 connected by slanted cross rods or frets 13 of shape substantially corresponding to the rods for reinforced concrete 8 of machine 1.
Machine 1 carries out slits 2 in panel 3 as follows.
Once panel 3 to be pierced has been placed on upright 14 with trolleys 6 in open position, as shown in figure 1, a common computerized control means of the PLC type controls the warming of the rods for reinforced concrete 8. Once the desired temperature has been reached, the approach of the two trolleys 6 is controlled up to reach the position of figure 2 with the rods for reinforced concrete 8 piercing panel 3. At the end-of-stroke point of figure 2, the rods for reinforced concrete 8 take the same position that will be taken by the slanted rods 13 of the reinforcement reticulation 10 after the final assembly.
After few seconds, the PLC controls the return of trolleys 6 to the position of figure 1 , removing the rods for reinforced concrete 8 from panel 3 which at the end of the process therefore exhibits slits 2 suitable to lodge the slanted rods 13.
Advantageously, the rods for reinforced concrete 8 have a slightly larger diameter than the slanted rods 13 of reticulation 10 due to the warming. Accordingly, an interspace 17 is formed between slanted rod 13 and panel 3 within slit 2 (figure 11). Even after laying plaster 32 onto the laid reticulated panel 50, this allows a better heat insulation. Moreover, the
non adhesion of the polystyrene to the slanted rod 13 by interspaces 17 allows a better anti-seismic behavior since panel 3 is more flexible and elastic.
The assembly of panel 3 with slits 2 and the reinforcement reticulation 10 occurs as follows.
A first reticulation 11 with flat meshes 12, carried out with filled welding on a horizontal plane, is laid; said first reticulation 11 is provided with slanted rods 13 crosswise said plane, welded with filling to said first reticulation 11. The arrangement of the slanted rods 13 corresponds to that of slits 2 of panel 3 so as to allow an easy coupling. Panel 3 with slits 2 is then placed on top of the flat reticulation 1 1 inserting the slanted rods 13 into slits 2.
A second reticulation 11 with flat meshes 12 is placed on top of panel 3 and the oblique rods 13, protruding from slits 2, are welded with filling to said second reticulation 1 1. The resulting panel 3 is perfectly "packed" between two flat reticulations 11 rigidly connected by slanted rods 13 crossing the panel.
Advantageously, there are no problems of dimensional variations due to the cooling of polystyrene since panel 3 is already formed prior to the assembly with the reinforcement reticulation. Accordingly, interspace 17 remains as well, which carries out the function of air bearing that ensures an increase in heat insulation of the self-bearing reticulated panel 50 according to the present invention.
Equally advantageously, it is possible to assemble the reticulated structure 10 to panel 3 without hazardous casting of foamy material in the semi-liquid state. The whole is carried out in cold conditions without any risks for the operator. The assembly may be carried out at the factory or at the building site.
