Abstract

The connection of concrete foundation post sections comprises terminal rings on the sections (1,6) with complementary mating surfaces (7,8) for connection in loose soils without the need for bonding by welding. Preferably, the top (4) and bottom (3) rings have rods (2,5) acting as reinforcement for the cement. Surfaces are made conical, and are bonded by pressing. ADVANTAGE - This design increases speed, economy and precision while excluding ring deformation.

RIVENDICAZIONI 1. Dispositivo per congiungere rapidamente, senza saldature, spezzoni di palo in cemento provvisti all'estremità di anelli, spezzoni da infiggere nel terreno per consentire la costruzione di fondamenta di edifici su terreni soffici, caratterizzato dal fal-to che gli anelli (3, 4) fissati all'estremità degli spezzoni (1, 6) sono reciprocamente incastratali cioè provvisti di superfici complementari (7, 8) tali da permettere l'incastro reciproco stabile a pressione, senza dover ricorrere a saldature.1. Device for quickly joining, without welding, sections of concrete pole provided with rings at the ends, sections to be driven into the ground to allow the construction of foundations for buildings on soft ground, characterized by the fact that the rings (3, 4) fixed to the ends of the sections (1, 6) are mutually interlocked, i.e. provided with complementary surfaces (7, 8) such as to allow stable reciprocal interlocking under pressure, without having to resort to welding. 2. Dispositivo secondo la rivendicazione 1, caratterizzato da un anello inferiore (3) e da un anello superiore (4) provvisti di ancoraggi in tondino (2 e 5) atti a costituire armatura per il cemento dei rispettivi spezzoni di palo e di superfici coniche complementari (7 e 8), reciprocamente incastrabili in modo definitivo e stabile senza dover ricorrere a saldature.2. Device according to claim 1, characterized by a lower ring (3) and an upper ring (4) provided with rod anchors (2 and 5) able to form reinforcement for the concrete of the respective pole sections and conical surfaces complementary (7 and 8), mutually interlocking in a definitive and stable way without having to resort to welding. DESCRIZIONEDESCRIPTION La presente invenzione ha per oggetto un dispositivo per congiungere rapidamente, senza saldature, spezzoni di palo in cemento, provvisti all'estremità di anelli, spezzoni da infiggere nel terreno per consentire la costruzione di fondamenta di edifici su terreni soffici.The present invention relates to a device for quickly joining, without welding, sections of concrete pole, provided at the ends with rings, sections to be driven into the ground to allow the construction of building foundations on soft ground. Sono noti dispositivi di agganciamento che adempiono la funzione sopra spiegata e che prevedono di applicare allo spezzone di palo superiore un anello inferiore e allo spezzone di palo inferiore un anello superiore e di congiungere stabilmente i due anelli mediante saldatura.Coupling devices are known which perform the function explained above and which provide for applying a lower ring to the upper pole section and an upper ring to the lower pole section and to join the two rings stably by welding. Essi presentano svantaggi sostanziali di cui i più importanti sono:They have substantial disadvantages of which the most important are: - maggiore difficolatà di costruzione dato che gli anelli, in lamiera saldata, sono facilmente deformabili;- greater construction difficulty since the rings, in welded sheet metal, are easily deformable; - maggior costo di fabbricazione per conferire alla lamiera una forma perfetta;- higher manufacturing cost to give the sheet a perfect shape; - maggior tempo e spese di posa per provvedere alla saldatura degli anelli;- more time and installation costs to provide for the welding of the rings; - minore precisione di agganciamento.- lower locking accuracy. Tutti questi invonvenienti sono superati dal dispositivo se-5 condo la presente invenzione.All these drawbacks are overcome by the device according to the present invention. Il dispositivo è caratterizzato dal falto che gli anelli fissati alle estremità degli spezzoni sono reciprocamente incastrabili cioè provvisti di superfici complementari tali da permettere l'incastro reciproco stabile a pressione, senza dover ricorrere a sal-10 dature.The device is characterized in that the rings fixed to the ends of the sections are mutually interlocking, ie provided with complementary surfaces such as to allow stable mutual interlocking under pressure, without having to resort to welding. Secondo una preferita forma di realizzazione, il dispositivo in oggetto, comprende un anello inferiore e un anello superiore provvisti di ancoraggi in tondino atti a costituire armatura per il cemento dei rispettivi spezzoni di palo e di superfici coniche complementari, reciprocamente incastrabili in modo definitivo e stabile senza dover ricorrere a saldature.According to a preferred embodiment, the device in question comprises a lower ring and an upper ring provided with rod anchors suitable for forming reinforcement for the concrete of the respective pole sections and with complementary conical surfaces, mutually interlocking in a definitive and stable way without having to resort to welding. A maggior chiarimento il disegno allegato rappresenta la suddetta preferita forma non limitativa di realizzazione del di-20 spositivo in oggetto.For further clarification, the enclosed drawing represents the aforementioned preferred non-limiting embodiment of the device in question. La parte meccanica di detto dispositivo consiste in un anello maschio (3) ed un anello femmina (4). I due anelli, d'acciaio, sono fabbricati a mezzo di laminazione a caldo. Le superfici coniche (7) e (8), servono a congiungere i due anelli, pressando-25 li uno nell'altro.The mechanical part of said device consists of a male ring (3) and a female ring (4). The two steel rings are manufactured by means of hot rolling. The conical surfaces (7) and (8) serve to join the two rings, pressing them 25 one into the other. A questo punto la pressione che tiene agganciati gli anelli è tale da rendere la saldatura dei medesimi superflua.At this point the pressure that keeps the rings hooked is such as to make their welding superfluous. Prima di essere agganciati tra di loro, l'anello maschio (3) e l'anello femmina (4) sono cementati all'estremità dei pali di ce-3o mento (1) e (6), usando gli ancoraggi in tondino (2) e (5) che fanno da aramatura per il cemento.Before being hooked together, the male ring (3) and the female ring (4) are cemented into the end of the concrete piles (1) and (6), using the rod anchors (2 ) and (5) which form the armor for the concrete. La forma degli anelli 3 e 4 e soprattutto degli incastri 7 e 8 potrà variare, come pure quella dei tondini 2 e 5, compatibilmente con quanto rivendicato, senza uscire dall'ambito di pro-35 tezione del brevetto. .The shape of the rings 3 and 4 and above all of the joints 7 and 8 may vary, as well as that of the rods 2 and 5, compatibly with what is claimed, without departing from the scope of protection of the patent. . vv 1 foglio disegni1 drawing sheet
