Machine (10) and method to produce structural elements for the building trade made of cement material with one or more inserts (12) made of polymer material. The machine (10) comprises at least a molding member, a loading unit (15) for loading the inserts (12) and a depositing member (16) to deposit the cement material. The molding member is open at the upper part and the loading unit (15) and the depositing member (16) are selectively positionable above the molding member in order to load and deposit from above, respectively, the inserts (12) and the cement material into the molding member, in order to achieve the structural elements.

L'invention a pour objet un procédé de fabrication d'un mur à coffrage intégré du type comprenant deux peaux béton délimitant entre elles un espace de coulée de béton, lesdites peaux étant reliées entre elles et maintenues écartées l'une de l'autre à l'aide de connecteurs, ledit procédé comprenant les étapes de : - coulée de béton pour la réalisation d'une première peau béton ; - plantage d'une première extrémité desdits connecteurs dans ladite première peau béton ; - séchage de ladite première peau béton ; - coulée de béton pour la réalisation d'une deuxième peau béton ; - retournement de ladite première peau de façon à orienter lesdits connecteurs vers le bas ; - plantage de l'autre extrémité, dite deuxième extrémité, desdits connecteurs dans ladite deuxième peau béton ; - séchage de ladite deuxième peau béton,
caractérisé en ce qu 'il comprend, consécutivement à ladite étape de mise en place desdits connecteurs dans ladite première peau béton, une phase de transmission d'ultrasons dans ledit béton par l'intermédiaire desdits connecteurs en vue d'entraîner une mise en vibrations dudit béton au voisinage de la première extrémité desdits connecteurs.

The present invention relates to a method and apparatus for producing a composite structure comprising a sheet metal bottom plate (6) and a concrete layer (18). The upper surface of the bottom plate (6) is provided with anchors (15) for anchorage to the overlying concrete, and the concrete layer (18) is cast over the bottom plate (6), and the concrete layer (18) is shaped by taking it through a bordered casting space (1, 5, 10, 13) and compacting it by virtue of a vibrating motion applied on at least one form wall of the casting space, said movement providing a vibrating area (7, 8) on said casting space.

The invention is concerned with a method and a mould for the casting of large-size concrete objects or elements for compacting the high-viscosity casting mix, the mould (3 or 17) comprising a bottom (8 or 24) and side walls (6,7) as well as, additionally, a deck (9 or 25) for bringing the high-viscosity casting mix present in the mould (3 or 17) mechanically under pressure. According to the invention, repeated parallel dislocations back and forth are produced in the various regional zones of the mechanically pressurized high-viscosity casting mix (1) present in the mould (3 or 17), and in particular in parallel dislocation planes (2) of the casting mix. This is achieved by pivoting two opposite mould (3 or 17) walls (4, 5) or wall portions (20, 21, 22, 23) in synchronism and always in the same direction in relation to each other or in relation to their corresponding portions provided in pairs, which pivoting takes place around shafts (10, 11 or 28, 29) placed at a distance from one another, included in the planes of the said mould walls, and being parallel to each other and to the parallel dislocation planes (2) of the casting mix (1).
摘要:
A plurality of inlet-side octagonal cells and outlet-side quadrangular cells partitioned by partition walls on an upper surface and a lower surface are opened in a green honeycomb molded body in which a plurality of through-holes partitioned from each other by the partition walls are open in an end surface of a columnar body. Four outlet-side quadrangular cells having a smaller opening area adjoin around one inlet-side octagonal cell through the partition walls. The partition walls are joined together and the inlet-side octagonal cells are opened while closing the outlet-side quadrangular cells on the inlet side and the outlet-side quadrangular cells are opened while closing the inlet-side octagonal cells on the outlet side in a particulate-matter-removing filter such as a diesel particulate filter.
摘要:
The method of manufacturing a honeycomb structured body of the present invention includes forming a ceramic block by binding multiple pillar-shaped honeycomb fired bodies with adhesive layers interposed therebetween. The honeycomb fired bodies each have many cells longitudinally disposed in parallel with each other and cell walls between the cells. Each cell wall of the honeycomb fired bodies has a thickness of 0.1 to 0.2 mm and each peripheral wall of the honeycomb fired bodies has a thickness of 0.25 to 0.5 mm. The ceramic block forming includes binding the multiple honeycomb fired bodies on a support by piling up the honeycomb fired bodies successively. The binding includes: determining a placing position where a primary honeycomb fired body is to be placed; fixing a position of an end face of at least one secondary honeycomb fired body by applying force to the end face of the secondary honeycomb fired body, the secondary honeycomb fired body being a honeycomb fired body whose side face is to be opposite to a side face of the primary honeycomb fired body below the placing position; and placing the primary honeycomb fired body on the placing position with the position of the end face of the secondary honeycomb fired body being fixed. The fixing further includes first positioning or second positioning based on the number of secondary honeycomb fired bodies before the fixing, the secondary honeycomb fired bodies each being placed on a position where a side face of the secondary honeycomb fired body is opposite to a side face of the primary honeycomb fired body to be placed. When the at least one secondary honeycomb fired body includes one secondary honeycomb fired body, the first positioning is performed to fix a position of an end face of only the single secondary honeycomb fired body. When the at least one secondary honeycomb fired body includes multiple secondary honeycomb fired bodies, the second positioning is performed to fix positions of first end faces of only the multiple secondary honeycomb fired bodies so as to align the positions of the first end faces of the multiple secondary honeycomb fired bodies.
