Description

       

  Construction en acier pour cintres et voûtes.

  
Il est connu de recouvrir de grands locaux ou. espaces, par exemple de grands halls, en employant dés fermes en arbalète ou

  
des fermes à contre-fiches en tôle d'acier. De. telles couvertures exigent des quantités considérables de fers profilés qui rendent

  
la construction lourde et coûteuse, en particulier quand il s'agit de recouvrir, ponter des surfaces de grande portée. Même la construction de plus petits ponts, par exemple pour le pontage de chemins, cours d'eau, etc. exige, malgré la portée plus petite, une quantité relativement grande de pièces de construction pour absorber la charge et garantir la sécurité, de l'ouvrage.

  
L'objet de la présente invention est une construction en

  
acier pour cintres et voûtes, obviant aux défauts mentionnés. ceci est obtenu, conformément à 1* invention, en employant, pour l'absorption des fortes charges développées dans de tels ouvrages., des pièces de construction qui, par suite de leur grande résistance à la traction, peuvent transmettre ou absorber une grande force. Dans ce sens, on utilise par exemple des fils d'acier étirés à froid

  
ou améliorés, ou des câbles ou torons de tels fils, ainsi que des barreaux en aciers alliés et non alliés améliorés.

  
Au dessin annexé est représenté, en deux formes différentes de réalisation, un toit cintré en tôle d'acier, fait des dits éléments de construction.

  
Un cintre 1 fait de tôles ou bandes d'acier, est relié à ses extrémités à des cornières 2. Entre les deux cornières 2, un câble 3 du type mentionné. est tendu par tendeurs 5 de telle manière que le cintre soit amené sous une tension additionnelle.

  
De ce fait, les charges qui agissent sur le cintre dans la direction de la flèche I sont transmises au câble tendeur 3 par la tôle ou la bande cintrée 1. Pour empêcher que des forces agissant latéralement dans la direction de la flèche II déterminent un déplacement. du cintre dans le sens de la flèche III, il est encore prévu des câbles tendeurs 4 s'étendant diagonalement, et reliés au cintre 1 par des appliques 6. Pour déterminer un raidissement plus accentué du cintre, on peut prévoir des lamelles de tôle 7, montées à écartements déterminés dans le dessus du cintre et reliées à celui-ci de manière connue par soudure.

REVENDICATIONS.

  
1. Construction en acier pour cintres et voûtes, caractérisée en ce que le-cintre ou la voûte se compose de tôles ou bandes d'acier (1) placées sous tension préalable en direction horizontale par des parties appropriées (3) de tension.



  Steel construction for hangers and vaults.

  
It is known to cover large premises or. spaces, for example large halls, by using firm dice in crossbow or

  
steel sheet strut trusses. Such covers require considerable quantities of profile irons which make

  
heavy and expensive construction, especially when it comes to covering, bridging large span surfaces. Even the construction of smaller bridges, for example for bridging paths, waterways, etc. requires, despite the smaller span, a relatively large amount of construction parts to absorb the load and ensure the safety of the work.

  
The object of the present invention is a construction in

  
steel for arches and arches, obviating the defects mentioned. this is obtained, in accordance with the invention, by employing, for the absorption of the strong loads developed in such works., construction parts which, owing to their great tensile strength, can transmit or absorb a great force. . In this sense, for example, cold drawn steel wires are used

  
or improved, or cables or strands of such wires, as well as bars of improved alloy and non-alloy steels.

  
In the accompanying drawing is shown, in two different embodiments, a curved sheet steel roof, made of said construction elements.

  
A hanger 1 made of steel sheets or strips is connected at its ends to angles 2. Between the two angles 2, a cable 3 of the type mentioned. is tensioned by tensioners 5 so that the hanger is brought under additional tension.

  
As a result, the loads acting on the hanger in the direction of the arrow I are transmitted to the tension cable 3 by the bent sheet or band 1. To prevent forces acting laterally in the direction of the arrow II from determining a displacement . of the hanger in the direction of arrow III, there are also provided tensioning cables 4 extending diagonally, and connected to the hanger 1 by brackets 6. To determine a more accentuated stiffening of the hanger, it is possible to provide sheet metal strips 7 , mounted at specified spacings in the top of the hanger and connected to it in known manner by welding.

CLAIMS.

  
1. Steel construction for hangers and vaults, characterized in that the hanger or vault consists of steel sheets or strips (1) placed under pretension in horizontal direction by appropriate tension parts (3).
