Description
CORPS DE CONSTRUCTION A ARMATURE EN TOLE EN PARTICULIER POUR PUITS ET GALERIES
DE MINES ET PROCEDE DE FABRICATION.
Des corps de construction, en particulier des plaques et des poutres, fabriqués au moyen de matières de charge ou d'addition telles par exemple que du sable, du gravier, des scories, cendres, pierres ponces naturelles et artificielles, farine de bois, tourbe, paille ou analogue en combinaison avec des liants, tels par exemple que du ciment, de la chaux, du gypse, des bitumes ou analogues, regoivent fréquemment, pour augmenter leur résistance, des armatures, le plus souvent sous forme de tiges d'aciers rondes, toiles
en acier ou analogues. Pour réaliser une économie de poids, on a également utilisé comme armatures des tôles minces lisses ou perforées. Pour l'obtention des résistances les plus élevées, ces armatures ne suffisent pas dans de nombreux cas d'application, et un retour aux armatures à tiges de fer rondes aurait pour conséquence dans ces cas une augmentation notable de la section et du poids du fer, et par conséquent du prix de la construction.
Dans les corps de construction connus jusqu'à présent, munis d'armatures en tôles lisses ou également perforées, se présente l'inconvénient que l'armature, en cas d'apparition éventuelle d'une pression latérale, favorise une séparation ou un cisaillement du corps de construction à hauteur de l'armature. La cause doit en être recherchée dans le fait que la surface d'adhérence entre le métal et le corps de construction est trop petite et que le corps de construction est en outre divisé par l'armature de tôle. On a également tenté de perforer les armatures de tôle pour obtenir de cette façon une liaison entre les parties du corps de construction disposées de part et d'autre de l'armature. Mais de cette manière, l'armature en tôle est de nouveau affaiblie.
En conséquence, conformément à la présente invention, on propose un corps de construction constitué de matières de charge et de liants dont la
CONSTRUCTION BODY WITH SHEET FRAME IN PARTICULAR FOR WELLS AND GALLERIES
OF MINING AND MANUFACTURING PROCESS.
Building bodies, in particular plates and beams, made from fillers or additives such as for example sand, gravel, slag, ash, natural and artificial pumice stones, wood flour, peat , straw or the like in combination with binders, such as for example cement, lime, gypsum, bitumens or the like, frequently receive, to increase their strength, reinforcements, most often in the form of steel rods round canvases
made of steel or the like. To save weight, thin smooth or perforated sheets were also used as reinforcements. To obtain the highest strengths, these reinforcements are not sufficient in many application cases, and a return to reinforcements with round iron rods would result in these cases in a notable increase in the section and weight of the iron. , and therefore the price of construction.
In the construction bodies known until now, provided with reinforcements made of smooth or also perforated sheets, there is the drawback that the reinforcement, in the event of possible appearance of a lateral pressure, promotes separation or shearing. from the construction body to the height of the reinforcement. The cause should be sought in the fact that the adhesion surface between the metal and the construction body is too small and the construction body is further divided by the sheet reinforcement. An attempt has also been made to perforate the sheet metal reinforcements in order to obtain in this way a connection between the parts of the construction body arranged on either side of the reinforcement. But in this way, the sheet metal reinforcement is again weakened.
Accordingly, in accordance with the present invention, there is provided a building body consisting of fillers and binders whose
