摘要： Described are improved devices and processes for manufacturing concrete articles, including concrete pipe. In one embodiment, the invention provides an apparatus that has a first platform that is located beneath the floor of a manufacturing facility. The first platform includes a top surface and is configured to move bi-directionally along an axis. Two form bases can reside on the top surface of the first platform, each form base further including a form core that extends vertically from the first platform through respective holes in a second platform that resides above the first platform at an elevation even with or just above the floor's surface. The second platform is configured to move bi-directionally with the first platform between one of two cranes disposed on either side of a concrete mixer. A form is placed over the first core, which is then positioned under the outlet of an auger that receives concrete from the mixer. After filling is complete, the first core is positioned under the first crane which provides ballast to compress the concrete, and the second core (with a form) is placed under the auger's outlet for filling. After compression of the first form complete, the form can be removed using an overhead crane, and the second core is relocated to the second crane for concrete compression.

摘要： A production system for automatically casting hollow bodies, in particular of concrete, in a casting mold, which comprises an inner mold (2), an outer mold (1), a bottom ring (3), and a top ring (4). Separate top rings (4) are used for the production, which remain on the top end of the pipe until the concrete has set sufficiently, to ensure that the shape and tolerances of the top end of the pipe are retained after casting. The system moreover includes a clamping chuck (15) for retaining the top ring during casting. The clamping chuck is equipped with a clamping device that includes a ring-shaped flexible hose and a slotted spring ring. When the hose is filled with compressed air from a compressed air source, it clamps the spring ring together around a gripping ring on the top ring.

摘要： An automated concrete pipe making machine that utilizes an automatic feeding system in which a feed tray and its feed pan are mounted on a carrier that moves from a retracted position into a feeding position where the feed tray is aligned with and locked to the pan at the top of the form or forms to be filled. At the appropriate time after the forms have been filled, the feed pan is withdrawn onto the feed tray, which is then unlocked from the top of the form and retracted.

摘要： The means for creating perforated concrete casing comprises a hollow cylindrical canister having a plurality of spaced apart rows of elongated openings formed therein. The elongated openings in each row are horizontally disposed and are vertically spaced. A first support means is secured to the outside surface of the canister adjacent each row of openings. A plurality of vertically spaced plates are mounted on each of the first support means and are selectively movable into and out of the openings of the associated row. A second support means extends upwardly through the canister and has a plurality of vertically spaced wedges mounted thereon. The second support means is movable towards the canister so that the wedges will penetrate the stiff concrete positioned adjacent the inside surface of the canister so as to create tapered perforations therein. Means is provided for rotating the canister so that the wedges may successively communicate with the row of perforations created by the plates on the first support means. The method comprises the steps of: (1) extending the plates on all of the first support means into the elongated openings formed in the canister; (2) depositing a layer of stiff concrete adjacent the inside surface of the canister so that the plates are imbedded therein; (3) removing the plates from the stiff concrete thereby creating rows of perforations in the concrete; (4) extending a row of vertically spaced apart wedges through the stiff concrete from the inside surface thereof so that the wedges communicate with the perforations so as to enlarge the same and to alter the shape thereof; (5) removing the wedges from the perforations; (6) repeating the wedging process until all of the perforations have been enlarged and altered; and (7) removing the canister from the stiff concrete.
摘要翻译：用于制造多孔混凝土外壳的方法包括一个中空圆筒形罐，其中形成有多个间隔开的细长开口的一排。每行中的细长开口水平设置并且垂直间隔开。第一支撑装置固定在靠近每排开口的罐的外表面上。多个垂直隔开的板安装在每个第一支撑装置上，并且可选择性地移入和移出相关行的开口。第二支撑装置向上延伸穿过罐并且具有安装在其上的多个垂直间隔开的楔形物。第二支撑装置可朝向罐移动，使得楔形物将穿过邻近罐的内表面定位的刚性混凝土，从而在其中形成锥形穿孔。提供了用于旋转罐的装置，使得楔形物可以连续地与由第一支撑装置上的板产生的一排穿孔连通。该方法包括以下步骤：（1）将所有第一支撑装置上的板延伸到形成在罐中的细长开口中; （2）在罐的内表面附近沉积一层刚性混凝土，使其嵌入其中; （3）从刚性混凝土中去除板，从而在混凝土中产生一排穿孔; （4）从其内表面延伸穿过刚性混凝土的一排垂直间隔开的楔形物，使得楔形件与穿孔连通，以便使其变大并改变其形状; （5）从穿孔中去除楔子; （6）重复楔入过程，直到所有穿孔被扩大和改变为止; 和（7）从刚性混凝土中取出罐。

摘要： Apparatus for ram forming monolithic plastic articles, which produces articles, such as clay pipe and fittings, without stress lines and without knit or bond lines. The apparatus includes a mold having an elongate cavity having an inside surface configuration corresponding to an outside surface of the article to be formed therein. Bore forming mandrels or rams are movable into the elongate cavity for forcing a compression formed mass of plastic clay to flow around the mandrels and fill the cavity and form the article with bores therein, the mandrels being removable from the cavity and the mold opened for removal of the article.
