Definitions
- the present invention refers to a disposable forinwork for insulated masonry in reinforced concrete .
- the American patent No. 5,390,459 refers to a disposable formwork for masonry in reinforced concrete which comprises two polystyrene panels which face each other and which are limited towards the outside by respective lateral surfaces, and at least two formwork spacers which are co-moulded together with the polystyrene panels, and which present respective pairs of terminal end plates, which extend in such a way as to abut the relative lateral surfaces, occupying all the height of the lateral surfaces themselves .
- the formwork spacers are generally made of plastic material, and the formworks are assembled to one another in such a way as to create walls which are provided with a number of vertical plastic bands, which are defined by the union between the terminal end plates in order to provide greater structural stability to the walls themselves, and which define discontinuities on the external surfaces of the walls which are otherwise constituted by the polystyrene of which the panels are made.
- the aim of the present invention is to produce a disposable formwork for insulated masonry in reinforced concrete which will be free of the above- described disadvantages.
- the formwork comprising two polystyrene panels which face each other and which are limited towards the outside by respective lateral surfaces, and at least two formwork spacers which are assembled together with the polystyrene panels, and presenting respective pairs of terminal end plates : the formwork being characterised by the fact that the terminal end plates extend in such a way as to abut the relative lateral surfaces and partially occupy a height of the lateral surfaces themselves.
- An additional aim of the present invention is also to produce a disposable formwork for insulated masonry in reinforced concrete, which will present a low volume in the transport phase, and which also be easy and quick to install.
- the hinges of the formwork spacers render any configuration whatsoever of the formwork instable, apart from the collapsed configuration.
- the disposable formwork for insulated masonry in reinforced concrete comprises, in addition, two hinges which are associated with each formwork spacer in order to permit the collapse of the disposable formwork itself in a transport configuration, and movement blocking devices of the hinges themselves in order to block the two polystyrene panels in a stable placement configuration.
- FIGURE 1 is an elevated lateral view of a first preferred form of embodiment of a disposable formwork for insulated masonry in reinforced concrete produced according to the present invention
- - FIGURE 2 is a plan view of the disposable formwork which is shown in FIGURE 1 in an operating placement configuration
- - FIGURE 3 is a plan view of the disposable formwork which is shown in FIGURE 1 in an operating
- FIGURE 4 is a lateral elevation view of the disposable formwork which is shown in FIGURE 1;
- FIGURES 5 and 6 illustrate, in perspective views, a detail of the disposable formwork which is shown in FIGURE 1 in respective operating configurations:
- FIGURES 7, 8 and 9 are frontal elevation schematic views, with some parts removed for reasons of clarity, of the same number - three - of preferred forms of embodiment of the disposable formwork which is shown in FIGURE 1;
- FIGURE 10 illustrates a perspective view from above of a detail of the disposable formwork which is shown in FIGURE 1; and - FIGURE 11 illustrates, on an enlarged scale and with some parts removed for reasons of clarity, a detail which is shown in FIGURE 10.
- the number 1 refers to a disposable formwork for insulated masonry in reinforced concrete in its entirety.
- the formwork 1 presents a major longitudinal axis A, and comprises two polystyrene panels 2 which face each other and are parallel to each other and to the axis A itself.
- the panels 2 are delimited towards the outside by respective external lateral surfaces 2e, and are both limited towards the inside by respective lateral surfaces 2i which are provided with a number of vertical recesses R.
- the recesses R extend for the whole of a height H of the panels 2, and present a shape in the form of a
- Each panel 2 which is preferably of a parallelepiped shape, is, in addition, delimited by an upper surface 2s and a lower surface 2f, which are parallel to each other and transverse to the relative surfaces 2i and 2e, and, with the aim of assembling a panel 2 itself with other panels 2, present a number of quadrangular bulges 3 and notches 4 which are arranged in rows parallel to the axis A in such a way that, as is illustrated in FIGURE 2, the bulges 3 and the notches 4 in one row are staggered in relation to the bulges 3 and the notches 4 in the adjacent row or
- the formwork 1 comprises two or more formwork spacers 10 which are preferably but not necessarily assembled by means of co-moulding to the panels 2, and each comprise, as is illustrated in FIGURES 4, 5 and 6, a respective intermediate crosspiece 11, and two anchoring portions 12 which are arranged at opposite ends of the crosspiece 11.
- each spacer 10 comprises two connecting hinges 13, which connect each portion 12 to the crosspiece 11, and which are suitable for permitting the rotation of each portion 12 in relation to the crosspiece 11 itself around a
- the crosspiece 11 comprises two bridge elements 11a and lib, which present an equal flattened shape, and which are arranged on the same plane and are parallel to each other, and are at a determined distance from each other in such a way as to define a window 14 in relation to each other, which is also
- the elements 11a and lib each comprise, and on each free longitudinal side, three flattened support
- each portion 12 is
- the plate 18 is arranged in such a way as to abut the surface 2i of the panel 2, and is provided, on the opposite side to the fins 20, with a rigid rib 21 which is transverse to the plate
- the elastic pins 22 are inserted inside the holes 16a of the relative bodies 16, and each comprise two forked teeth 23 which face each other in order to form an open notch 24, and, for each tooth 23, a blocking undercut 25 which is arranged outside the body 16 in order to axially block the body 16 and the pin 22 themselves.
- each plate 18 may be provided, in the place of the relative plate 19 and the relative connecting fin 20, with a grooved rib in the shape of a swallow' s tail in such a way that it can be firmly inserted inside a relative recess R.
- a grooved rib in the shape of a swallow' s tail in such a way that it can be firmly inserted inside a relative recess R.
- the plate 19 is arranged outside the panel 2 in order to permit the easy identification of the position of the relative formwork spacer 20 along the panel 2 itself, and is arranged in such a way as to completely abut the surface 2e of the panel 2 itself.
- the plate 19 presents a length L of dimensions which are less than the height H of a panel 2, or rather of dimensions which are less than the distance between the surfaces 2e and 2f of the panel 2 itself.
- the different dimensions of the length L and the height H permit the panels 2 to be placed one over the other in order to form the above-mentioned continuous band of plastic, but leave between one plate 18 and two equally vertical plates 19 a space of dimensions which are sufficient to permit the direct adhesion of the plaster to the polystyrene of the panels 2.
- FIGURE 3 the hinges 13, which permit the rotation of each portion 12 in relation to the relative crosspiece 11, consequently permit both the collapse of the formwork 1 in a transport configuration, in which the two panels 2 are arranged next to each other, and the positioning of the formwork 1 itself in a placement configuration (see FIGURE 2) corresponding to the homologous placement configuration of the spacers 10, and in which the two panels 2 are arranged at a distance from each other which is equal to the length of the crosspiece 11.
- each body 16 comprises a flat frontal face 161 which is arranged opposite the body 16 itself in relation to the relative element 11a or lib, and two flat lateral faces 162, which are arranged parallel to each other and transverse to the face 161, and which are connected to the face 161 itself by means of two arch-shaped cams 163.
- Each body 16 together with a relative pin 22 and together with the body 16 and the pin 22 which are arranged on the same axis B forms a hinge 13, and each body 16 is always arranged with its own surface 16s abutting the relative plate 18, and the faces 161
- each pin 22 defines a blocking element of the relative position between the crosspiece 11 and the portions 12, permitting both the safe transport of the panel 2, as well as a correct and rapid positioning of the panel 2 itself.
- the surfaces 162 present in plan view a shape which is substantially that of a rectangular trapezoid, while the surface 161 presents
- the surfaces 161 and 162 are both arranged with their own major bases on the same side of the body 16 and confer s substantially conical development on each cam 163.
- the plates 19 are no longer completely outside the panel 2, but comprise a portion 19' which is embedded inside the panel 2, and a portion 19" which is exposed outside the panel 2 itself and which is integral with the embedded portion 19' .
- the plates 19 no longer have a completely flat geometry, but present a central concavity 30 defining the portion 19' , and two end fins 31, which define the portion 19", and are arranged outside and abutting the panel 2.
- the fins 31 are connected to a base 32 of the concavity 31 by respective connecting portions 33 which are oblique both in relation to the fins 31 and in relation to the base 32 themselves.
- the plates 19 present a configuration which is a mirror image of the configuration of the plate 19 which is shown in FIGURE 7 and, thus, the fins 31 are
- the plates 19 present a Greek fret configuration, in which the portion 19' and the portion 19" are alternated in relation to each other, and are connected by portions 33 which are transverse to the portions 19' and 19".
