摘要:
A device (1) for manufacturing a three-dimensional object by a layer wise solidification of a building material at positions in the respective layers that correspond to the object is provided. A feed (96) that supplies the building material to a building space (10) in the device (1) and at least two filler portions (98a, 98b) that are provided at the feed (96) and are independent from one another are provided, wherein one connector (99a, 99b) is provided for each building material supply container (100a, 100b) in order to supply the building material from outside of the device (1).
摘要:
A method for manufacturing concrete panels by continuously pressing and an apparatus for carrying out the method. The concrete panels are successively manufactured by continuously feeding pallets onto a conveyor, feeding a concrete material onto the pallets, continuously pressure frames against the concrete material from the upper side and both lateral sides of the concrete material while imparting vibrations to the pressure frames, forming hollows in the concrete material by thrusting a rotary screw-type core rod therethrough to provide a panel shape hollow molding, and cutting the molded concrete material into a length corresponding to the length of each pallet. In the manufacture process, an organic or inorganic fiber material may be incorporated into the concrete material for the purpose of reinforcement of the finished products.
摘要:
Apparatus for mechanically forming a random rake finish on the surface of a cast panel utilizes counter rotating sets of tines which are projected into the material as a form is linearly moved. The apparatus thus is used to implement a unique method of providing a random rake or fuzzy finish on the surface of the cast panel.
摘要:
An apparatus for lining a container comprising a vibration-pressing mold to be placed on a refractory mix charged in the container, the outer shell of the mold being composed of a metal plate, a vibration-transfer frame provided on the inside of the metal plate, a plurality of vibrators provided on the vibration-transfer frame, an anti-vibration member provided on the upper end of the mold, a supporting frame for supporting the mold with the antivibration member inserted therebetween, a weight placed on the supporting frame, and a guide member for maintaining the mold in a stabilized posture during its sink-down into the refractory mix.
摘要:
Apparatus for forming in one operation a molded article having box-like sides such as a concrete meter box, and a molded covering lid therefor. A cavity in the shape of connected sides of a box is formed between an inner form and a surrounding outer form. An open top lid form rests on the top of the inner form, its outside surface extending out beyond the top of the inner form to define a shoulder and an upper extension of the cavity. The cavity and the lid form are filled with a settable material and vibrated. A power unit then raises the box-like article by engaging a pallet beneath the article at the bottom of the cavity, the box-like article being capable of carrying the lid form upwardly with it by engagement of the finished article with the shoulder of the lid form.
摘要:
A plant for manufacturing reinforced concrete elements in the shape of a case, having working stations connected by conveyors and which working stations mold an open top box, form a lid strip for said box and include concrete pouring stations, concrete vibrating stations, mould moving and lifting station, lid strip smoothing station and a station for cutting said lid strip into individual strips.
