“CASSERO A SCOMPARSA PER LA COSTRUZIONE DI SOLETTE DA “RETRACTABLE FORMWORK FOR THE CONSTRUCTION OF SLABS FROM
IMPIEGARE NELL'EDILIZIA" EMPLOY IN BUILDING "
La presente invenzione riguarda un cassero a scomparsa, preferibilmente realizzato in materiale plastico riciclato, per la fabbricazione di solette da utilizzare nelle costruzioni edili. The present invention relates to a retractable formwork, preferably made of recycled plastic material, for the manufacture of slabs to be used in building constructions.
Tali solette consistono in lastre di calcestruzzo armato, semplici o con nervature, e costituiscono la struttura portante di diversi elementi costruttivi come solai, ponti, fondazioni e simili. These slabs consist of reinforced concrete slabs, simple or with ribs, and constitute the load-bearing structure of various construction elements such as floors, bridges, foundations and the like.
Normalmente, la struttura risulta composta da due lastre piane, sovrapposte e distanziate con l'interposizione di nervature in calcestruzzo ortogonali fra loro e costituenti un collegamento fra le due lastre. Tale struttura deve soddisfare requisiti di resistenza ai carichi, ma al tempo stesso deve essere per quanto possibile leggera. L'alleggerimento della struttura si ottiene generalmente impiegando dei blocchi di materiale plastico, come polistirolo, che rimane inglobato nella gettata di calcestruzzo. Normally, the structure is composed of two flat slabs, superimposed and spaced apart with the interposition of orthogonal concrete ribs to each other and forming a connection between the two slabs. Such a structure must meet load resistance requirements, but at the same time it must be as light as possible. The lightening of the structure is generally obtained by using blocks of plastic material, such as polystyrene, which remains incorporated in the concrete casting.
Queste solette di tipo noto presentano degli svantaggi in quanto vengono prodotte lontano dai luoghi di impiego e in dimensioni standardizzate, in particolare per quanto riguarda le lunghezze, e quindi non consentono la necessaria adattabilità alle condizioni operative in cantiere. Inoltre, esse presentano problemi tecnici di trasporto dai luoghi di produzione ai cantieri in cui vengono impiegate, con relativi aumenti dei costi. These known type slabs have disadvantages in that they are produced far from the places of use and in standardized dimensions, in particular as regards the lengths, and therefore do not allow the necessary adaptability to the operating conditions on site. Furthermore, they present technical transport problems from the production sites to the sites where they are used, with relative cost increases.
Il brevetto EP 0 884 427 descrive una soletta realizzabile in cantiere con l'impiego di elementi scatolari (casseri a scomparsa) realizzati con materiali plastici riciclati che vengono incorporati in una gettata di calcestruzzo. Gli elementi scatolari sono costituiti da un contenitore a forma di piramide con la base maggiore aperta verso l'alto e chiudibile mediante un coperchio piano che si appoggia su elementi troncoconici che si ergono verticalmente aH'intemo del contenitore. Dal fondo chiuso del contenitore si estendono inferiormente dei piedini che possono inserirsi nelle maglie di una rete metallica che costituisce Tannatura della soletta. I bordi del coperchio e del contenitore sono dotati di linguette forate che consentono il fissaggio reciproco mediante viti o bulloni. Inoltre, nel coperchio viene inserito un risalto opportunamente profilato che serve per fissare al contenitore tubi, cavi elettrici o simili. Infine, elementi contigui possono essere collegati tra loro mediante piastrine di connessione o simili. Questa soluzione può essere realizzata in cantiere superando le limitazioni ed evitando gli inconvenienti della soluzione tradizionale precedentemente descritta. Tuttavia, risulta evidente che si tratta di una soluzione piuttosto complicata che richiede di assemblare molti pezzi separati, impiegando una notevole quantità di elementi di fissaggio. Ciò comporta molto lavoro di mano d'opera, lunghi tempi di allestimento e costi elevati. Patent EP 0 884 427 describes a slab that can be made on site with the use of box-like elements (retractable formworks) made with recycled plastic materials which are incorporated into a concrete casting. The box-shaped elements consist of a pyramid-shaped container with the main base open upwards and closed by means of a flat lid that rests on truncated cone elements that rise vertically inside the container. Feet extend from the closed bottom of the container which can be inserted into the meshes of a metal mesh which forms the tanning of the insole. The edges of the lid and the container are equipped with perforated tabs that allow mutual fixing by means of screws or bolts. Furthermore, a suitably profiled projection is inserted in the lid which serves to fasten pipes, electric cables or the like to the container. Finally, contiguous elements can be connected to each other by means of connecting plates or the like. This solution can be implemented on site overcoming the limitations and avoiding the drawbacks of the traditional solution described above. However, it is evident that this is a rather complicated solution which requires to assemble many separate pieces, using a considerable amount of fasteners. This involves a lot of labor, long set-up times and high costs.
Il brevetto WO 01/03898 descrive una soluzione analoga alla precedente in cui l'elemento scatolare è costituto da due semigusci che vengono sovrapposti e accoppiati mediante rispettivi elementi di riscontro. Anche in questo caso l'allestimento dei singoli casseri e il collegamento di casseri contigui si presenta difficoltoso. Patent WO 01/03898 describes a solution similar to the previous one in which the box-like element is constituted by two half-shells which are superimposed and coupled by means of respective abutment elements. Also in this case the preparation of the individual formworks and the connection of contiguous formworks is difficult.
Il brevetto WO 01/57335 descrive una soluzione diversa da quelle precedentemente citate, in quanto l'elemento di cassero a scomparsa è costituito da un corpo cavo con la cavità rivolta verso il basso, che viene disposto fra uno strato di rinforzo inferiore e uno strato di rinforzo superiore della soletta. Il corpo è dotato di distanziali lungo il suo bordo inferiore e quello superiore; inoltre, sono previsti dei rinforzi verticali che vengono montati fra blocchi di tre corpi cavi adiacenti. Questa soluzione è più semplice di quelle precedentemente citate ma presenta ancora qualche svantaggio, in particolare dovuto alla forma degli elementi che rende incerto il loro collegamento e la necessità di elementi di rinforzo nella posa in opera. Patent WO 01/57335 describes a different solution from those previously cited, since the retractable formwork element consists of a hollow body with the cavity facing downwards, which is arranged between a lower reinforcement layer and a layer upper reinforcement of the insole. The body is equipped with spacers along its lower and upper edges; furthermore, vertical reinforcements are provided which are mounted between blocks of three adjacent hollow bodies. This solution is simpler than those previously mentioned but still has some disadvantages, in particular due to the shape of the elements which makes their connection uncertain and the need for reinforcing elements during installation.
Scopo principale della presente invenzione è quello di proporre un nuovo tipo di cassero a scomparsa per la fabbricazione di solette da impiegare nelle costruzioni edili, in modo che queste, a parità di resistenza, risultino più leggere di quelle attualmente realizzabili. Il nuovo cassero deve, inoltre, essere producibile stampando un unico pezzo di materiale plastico riciclato, in modo da ridurre i costi di fabbricazione e di posa in opera. In definitiva, il nuovo cassero deve consentire di allestire in cantiere solette delle dimensioni richieste, con il minimo impegno di tempo e di mano d'opera, e quindi particolarmente economiche. The main purpose of the present invention is to propose a new type of retractable formwork for the manufacture of slabs to be used in building constructions, so that these, with the same resistance, are lighter than those currently achievable. The new formwork must also be manufactured by molding a single piece of recycled plastic material, in order to reduce manufacturing and installation costs. Ultimately, the new formwork must make it possible to set up slabs of the required dimensions on site, with the minimum commitment of time and manpower, and therefore particularly economical.
Questi scopi vengono raggiunti con un cassero secondo l'invenzione essenzialmente costituito da un corpo cavo di forma tronco-piramidale con il vertice verso l'alto, le cui superfici laterali presentano delle lesene incavate e la cui superficie è divisa in settori sagomati con una pluralità di rilievi. These purposes are achieved with a formwork according to the invention essentially consisting of a hollow body with a truncated pyramid shape with the vertex upwards, the lateral surfaces of which have recessed pilasters and the surface of which is divided into shaped sectors with a plurality of reliefs.
Vantaggi e caratteristiche del cassero secondo l'invenzione risulteranno evidenti dalla descrizione che segue, a titolo esemplificativo e non limitativo, con riferimento ai disegni allegati, in cui: Advantages and characteristics of the formwork according to the invention will become evident from the following description, by way of non-limiting example, with reference to the attached drawings, in which:

la Figura 9 mostra schematicamente, in vista assonometrica, un gruppo di casseri assiemati e annegati nel calcestruzzo. Figure 9 schematically shows, in an axonometric view, a group of formworks assembled and embedded in the concrete.
- la Figura 10 mostra in sezione secondo la linea D-D il gruppo di casseri assiemati di Figura 9. - Figure 10 shows in section along the line D-D the group of assembled formworks of Figure 9.
Il cassero a scomparsa mostrato nelle Figure da 1 a 7 è costituito da un unico corpo cavo 11, a forma tronco-piramidale aperto verso il basso. Il cassero 11 viene preferibilmente fabbricato utilizzando materiale plastico riciclato. The retractable formwork shown in Figures 1 to 7 consists of a single hollow body 11, with a truncated pyramid shape open downwards. The formwork 11 is preferably manufactured using recycled plastic material.
I quattro spigoli 12 verticali del corpo cavo 11, che costituiscono sostanzialmente delle lesene, sono smussati lungo una superficie conica o piramidale con il vertice verso il basso e la pareti laterali 13 sono leggermente inclinate rispetto al piano verticale, in modo da rendere i casseri facilmente impilabili per comodità di trasporto. Alla base di ciascuno spigolo verticale 12 è ricavato un piedino 14 di forma preferibilmente troncoconica e diretto verso il basso. I piedini 14 possono essere di lunghezza diversa, in funzione del tipo di soletta da ottenere, e consentono di distanziare il bordo inferiore del cassero 11 dal piano di appoggio della soleta, per consentire la collocazione di barre di armatura anche nella parte inferiore della soleta e per otenere un diverso spessore del calcestruzzo soto gli elementi del cassero. The four vertical edges 12 of the hollow body 11, which substantially constitute pilasters, are beveled along a conical or pyramidal surface with the vertex down and the side walls 13 are slightly inclined with respect to the vertical plane, so as to make the formworks easily stackable for convenience of transport. At the base of each vertical edge 12 there is a foot 14 preferably of a truncated cone shape and directed downwards. The feet 14 can be of different lengths, depending on the type of slab to be obtained, and allow the lower edge of the formwork 11 to be spaced from the support surface of the slab, to allow the placement of reinforcing bars also in the lower part of the slab and to obtain a different thickness of the concrete under the formwork elements.
Le lesene 12, particolarmente per la loro forma consentono una migliore impilabilità dei corpi 11 durante il trasporto e rimmagazzinamento. Esse possono essere ricavate anche sulle superfici laterali del corpo 11; in tale caso contribuiscono aH'irrigidimento del medesimo. The pilasters 12, particularly due to their shape, allow a better stackability of the bodies 11 during transport and storage. They can also be obtained on the lateral surfaces of the body 11; in this case they contribute to the stiffening of the same.
La superficie superiore 15 del corpo 11 è sagomata con due canali 16 e 17 ortogonali tra loro e rispeto ai lati della superficie, in detti canali potendo essere alloggiati eventuali elementi impiantistici quali tubi o cavi. I canali 16 e 17 dividono la superficie superiore 15 del corpo 11 in quattro setori provvisti di una pluralità di rilievi 18. Deti rilievi sono preferibilmente di forma parallelepipeda e sono orientati secondo due direzioni ortogonali tra loro e parallele alle diagonali della superficie 15. Preferibilmente, i rilievi 18 di due setori contrapposti lungo una diagonale sono disposti paralleli tra loro e ortogonali rispeto ai rilievi degli altri due setori contrapposti lungo l'altra diagonale della superficie 15. Tali rilievi 18 hanno lo scopo di irrigidire la superficie superiore del corpo 11, per consentire la sua calpestabilità da parte degli operatori durante le fasi di allestimento della soleta. Inoltre, essi costituiscono elementi distanziatori delle barre di armatura dalla superficie superiore del corpo 11. The upper surface 15 of the body 11 is shaped with two channels 16 and 17 orthogonal to each other and with respect to the sides of the surface, in said channels any plant elements such as pipes or cables can be housed. The channels 16 and 17 divide the upper surface 15 of the body 11 into four sectors provided with a plurality of reliefs 18. Said reliefs are preferably parallelepiped in shape and are oriented in two directions orthogonal to each other and parallel to the diagonals of the surface 15. Preferably, the reliefs 18 of two opposite setsors along a diagonal are arranged parallel to each other and orthogonal with respect to the reliefs of the other two opposing sets along the other diagonal of the surface 15. These reliefs 18 have the purpose of stiffening the upper surface of the body 11, in order to allow its walkability by operators during the stages of setting up the slab. Furthermore, they constitute spacer elements of the reinforcing bars from the upper surface of the body 11.
Al di soto della superficie 15 sono normalmente ricavate delle nervature di irrigidimento (non mostrate), che rinforzano ulteriormente la superficie superiore del corpo 11 per aumentarne la resistenza ai carichi di lavoro. Inoltre, la superficie 15 è dotata di alcuni fori 19 (Figura 2), le cui dimensioni devono essere convenientemente piccole per consentire lo sfiato dell'aria dalla cavità del corpo 11 ma non l'ingresso di calcestruzzo. Underneath the surface 15, stiffening ribs are normally formed (not shown), which further reinforce the upper surface of the body 11 to increase its resistance to working loads. Furthermore, the surface 15 is equipped with some holes 19 (Figure 2), the dimensions of which must be conveniently small to allow the air to be vented from the cavity of the body 11 but not the entry of concrete.
Un'ulteriore caratteristica del cassero 11 è rappresentata dal fatto che da ciascun lato del suo bordo inferiore si estende una linguetta piana 20, la quale è provvista, rispettivamente, di una pluralità di fori oppure di un perno per il collegamento con la corrispondente linguetta di un cassero adiacente. La pluralità di fori consente di definire secondo necessità la distanza tra i casseri adiacenti in modo da ottenere solette di dimensioni diverse. A further characteristic of the formwork 11 is represented by the fact that a flat tongue 20 extends from each side of its lower edge, which is provided, respectively, with a plurality of holes or with a pin for connection with the corresponding an adjacent formwork. The plurality of holes allows the distance between the adjacent formworks to be defined as needed in order to obtain slabs of different sizes.
La Figura 8 mostra, in vista assonometrica schematica, un esempio di quattro casseri 11 assiemati su un tavolato 30 di appoggio. Si può apprezzare la notevole semplicità dell'operazione richiesta e la facile adattabilità dei casseri alle dimensioni della soletta da ottenere. Basta infatti accostare i diversi corpi cavi Il e collegare le rispettive linguette 20 inserendo i perni delle une nei fori prescelti delle altre. Figure 8 shows, in a schematic axonometric view, an example of four formworks 11 assembled on a support plank 30. The remarkable simplicity of the required operation and the easy adaptability of the formworks to the dimensions of the slab to be obtained can be appreciated. In fact, it is sufficient to bring the different hollow bodies 11 together and connect the respective tabs 20 by inserting the pins of one into the selected holes of the others.
La Figura 9 mostra ancora in vista assonometrica schematica e parzialmente sezionata, una soletta ottenuta con l'impiego di casseri 11 secondo l'invenzione. Come si può notare, sul tavolato 30 di appoggio è stata disposta una rete metallica 31, che costituisce un'armatura inferiore di rinforzo, e sopra i corpi 11 è stata disposta una seconda rete metallica 32, che costituisce un'armatura superiore di rinforzo. La colata di calcestruzzo 33 riempie tutti gli spazi fra i casseri 11 e forma uno strato inferiore che incorpora l'armatura 31, potendo passare al di sotto dei casseri 11 che rimangono sollevati rispetto al tavolato 30 grazie alla presenza dei piedini 14. Il particolare disegno della superficie 15 dei casseri 11, visibile nelle figure e descritto in precedenza, facilita poi la incorporazione anche deH'armatura superiore 32 nella colata di calcestruzzo 33. Il calcestruzzo, infatti, penetrando tra i rilievi 18 della superficie 15 può avvolgere completamente le barre del'armatura. Figure 9 again shows in schematic and partially sectioned axonometric view, a slab obtained with the use of formworks 11 according to the invention. As can be seen, a metal mesh 31 has been arranged on the supporting plank 30, which constitutes a lower reinforcement armature, and above the bodies 11 a second metal mesh 32 has been arranged, which constitutes an upper reinforcement armature. The poured concrete 33 fills all the spaces between the formworks 11 and forms a lower layer which incorporates the reinforcement 31, being able to pass under the formworks 11 which remain raised with respect to the plank 30 thanks to the presence of the feet 14. The particular design of the surface 15 of the formworks 11, visible in the figures and described previously, also facilitates the incorporation of the upper reinforcement 32 into the pouring of concrete 33. The concrete, in fact, penetrating between the reliefs 18 of the surface 15 can completely envelop the bars of the 'armor.
La Figura 10, infine, mostra in sezione il gruppo di casseri assiemati di Figura 9, in modo da mettere in chiara evidenza la distribuzione e la penetrazione del calcestruzzo 33 tra i vari elementi componenti la struttura, in particolare incorporando completamente le barre di armatura 31 disposte al di sopra e al di sotto degli elementi di cassero. Finally, Figure 10 shows in section the group of assembled formworks of Figure 9, so as to clearly highlight the distribution and penetration of the concrete 33 between the various elements making up the structure, in particular by completely incorporating the reinforcement bars 31 arranged above and below the formwork elements.
