Title (EN) METHOD AND APPARATUS FOR THE MANUFACTURE OF BUILDING STRUCTURAL BLOCKS
(FR) METHODE ET APPAREIL DE FABRICATION DE BLOCS DE STRUCTURE DE CONSTRUCTION
Abstract: front page image
(EN)A method and an apparatus for the manufacture of building structural members of straw material in block form. The straw material is collected and oriented so that strong connection is obtained in the horizontal direction as well as in the vertical direction in block form. The block (21) of straw material is placed in a heating oven (4, 6) located in the apparatus, grasped by transferring arms (9) along the short sides thereof in its center point, rotated before suitable heating sources (3) until the complete block (21) has received a temperature of between 80 and 130 C. The so heated block (21) of straw material in heated condition is transferred to a press (17-20), wherein the block (21) is compressed in vertical and horizontal direction and then the heated and compressed block (21) is cooled to the temperature of the surroundings with maintained compression force.
(FR)Methode et appareil de construction d"elements de structure de construction en materiau de paille sous forme de bloc. La paille est amassee et orientee de sorte qu"une liaison solide soit obtenue dans le sens horizontal et dans le sens vertical sous forme de bloc. Le bloc (21) de paille est place dans un four de chauffage (4, 6) situe dans l"appareil, saisi par des bras de transfert (9) sur ses petits cotes en son point central, tourne devant des sources de chaleur appropriees (3) jusqu"a ce que le bloc entier (21) atteigne une temperature de 80 a 130 C. Le bloc ainsi chauffe (21) de materiau de paille est transfere a chaud vers une presse (17-21), ou le bloc (21) est comprime dans le sens vertical et dans le sens horizontal puis le bloc chauffe et comprime (21) est refroidi a temperature ambiante en maintenant la force de compression.
