The present invention relates to aprocess of producing solid and hollow reenforced' concrete constructions such-as concrete poles and the like, and has for its object to prevent as much as possible fine cracks in the con-'- crete, which soon damage the latter and render the construction useless.
These hairline cracks, which develop in a very troublesome manner in the existing type of reenforced concrete constructions,are prevented, according to the present invention, by tensloning reenforcement bars up to their elastic limit before the, concrete is rammed and by compressing the-still liquid concrete l bymeansofa press plate guided by the rethe accompanying drawing of a pole, in which Figure 1 is a view of the reenforcement bars under tension; Fig. 2,"aperspective view of the lower tension plate; Fig.3, a view of the finished pole; Fig. 4:, a section on the'line the nuts 4. The ends of the reenforcement bars are attached by the nuts 5 to the tension plate 6 provided with the books 7 which .en-
gage the eyelets Qarranged in a wall 8 or the like. The'head plate 1 is fitted with an eyelet 1O hooked up with a tensioning device ll comprising a sort of tackle which in turn has a hook adapted to engage the eye let 12 arranged in a wall or the like; Both the tension plate 6 and the press plate 3 ha ve a central aperture 13 through which/a core 14: (Fig. 5) can be inserted to obtain a hollow pole. l
The process of producing reenforced concrete constructions according to this inven-, V tionf consists 1n tensiomng the reenforcement the core is the radial projections 15 for the purpose of providing the requisite climbing One form of the invention isv illustrated in bars 2 to their elastic limit by means of the l tightening device 11', inserting the core 14 through the apertures 13 0f the press and 7 tension plates 3 and-6, and in arranging in openings 16, whereupon the reenforcement;
bars'are covered helically with the wire 17.
Over and around the tensioned reenforcement bars 2, wich have, been provided with the cores 14 and l5, the mold 18 is arranged so that liquid concrete canbe successively rammed intoit, whereupon it is gradually being closed and its parts are tightened by 'means" of the screws'19. As soon as this has 6 been done, the nuts 4 of the press plate 3 are tightened as far as possible so that the press plate 3 can be shifted on the reenforcement bars? in the direction of arrow Ito compress the still liquid concretemass 20, Q the water containediin the latter escaping" through the mold 18 or on the two face sides,
soth at the concrete becomes Very d e and V is free from pOI'0S1ty,
After the concrete-mass2O has hardened Y completely the nuts& ofthe'tension plate 3 are tightened as much as possible while the tightening devicell is relieved. Thereen-f' forcement bars 2 are thus enclosed inten-i sioned condition in the concrete,-and the tensile stress still present in th'em is absorbed or taken up by the set concrete ascompressive stress.
7 Aside from forced concrete constructions canjbe produced in this manner and will be superior T to the prevailing types employing untensioned reenforcements in so far as. they will show much greater strength at lower-weight.
The number of reenforcement means used as well as the shape and cross section of the constructions can be altered to suit repoles all other kinds'of 'reen- I quirements Without affecting the inventionl V V The process of reenforcing concrete consisting in forming a body of concrete with the reenforcement embedded therein, in tensioning the reenforcement upto its elastic limitbefore theconcrete is rammed, in com V Signature.
pressing the still liquid concrete by suitable, apertured means guided by the reenforcement,-and finally in releasing the tensioning means after the concrete has set.
