摘要： A pre-stressed concrete pipe is made by casting a concrete pipe inside a metal cylinder and then being pre-stressed by injecting solidifying compound under pressure into the boundary between the metal cylinder and concrete pipe, and includes a pair of end rings within the metal cylinder, each having a metal ring with an annular groove and an elastic band having a curved end to provide a rounded corner on the concrete pipe. After the solidifying compound is solidified, the concrete pipe retains the compression increasing its strength to withstand pressure, and moments caused by external loads. The pre-stressed concrete pipe further includes a bell ring mounted at one end and a spigot ring having a gasket ring at the other end. A bell clamp is mounted on the bell ring.

摘要： The components forming the layers of a composite pipe are successively introduced into a rotary drum (1). Initially, a plastic reinforcing lyaer (8), including a fiber reinforcement, is introduced into the drum, the ends of the drum (1) being bounded by rings. A concrete core layer (16) is then introduced and the length of the core layer (16) is shortened relative to that of the drum (1) by shaping rings fixed to the drum ends. The shaping rings are then replaced by other shaping rings (20, 21) so that, on either side of the core layer (16), two annular spaces (22, 23) are formed which are filled by a socket material (24, 25) of the same composite as the reinforcing layer (8). Thus, at one pipe end a socket end (28) is formed and at the other pipe end a spigot end (30) is formed, each such end being located within the composite pipe wall thickness. After introducing a second reinforcing layer (26), the production of the composite pipe is completed. By producing the socket connecting elements (28, 30) simultaneously with the construction of the composite pipe, a reliable and rational production of the composite pipe with its socket connecting elements (28, 30) is achieved. By shaping a shoulder (33) on the spigot end (30), when sliding together two composite pipes, the socket end (28) is centered. Simultaneously, an annular space (34) is formed, in which can be inserted an elastic seal (35) for drip-tight sealing.

摘要： A device is described for positioning a reinforcing cage within a cylindrical concrete pipe form. The device comprises a horizontally movable slide which may be moved inwardly into the form for engagement with the cage. A cam is secured to the slide for moving the slide inwardly and outwardly relative to the form. An air cylinder is pivotally connected to the cam for pivotally moving the cam. An adjustable stop is located in the pivotal path of the cam to limit the inward movement of the slide. A plurality of the devices are mounted on the form in a radially spaced and vertically spaced manner.

摘要： A mould arrangement for shaft rings or the like in which the hat-shaped mould core comprises a core segment consisting of a cover portion with, adjacent thereto, a wall portion which is adapted for displacement horizontally into a closed position completing the shaped contours of the mould core and inwardly into a release position for removal of the form work. The mould core has a fit-in device for the cementing in of projecting elements, above all climbing irons, from the interior into the concrete part which is to be formed and during the shaping process. In addition to the core segment, the fitting-in device has for each climbing iron a housing, a clamping device associated therewith, and a clamping drive common to all these. Together with these parts, the core segment is detachably and exchangeably so mounted on the remainder of the mould core that it can be coupled to or uncoupled from the horizontal translatory drive. Thus, while retaining the rest of the mould core, the core segment can be exchanged for a different one. As a result the investment costs for individual mould cores are substantially reduced.
摘要翻译：一种用于轴环或类似物的模具装置，其中帽形模芯包括由相邻的盖部分组成的芯部分，该壁部分适于水平位移到闭合位置，从而完成成形轮廓模芯，并且内部进入释放位置以移除模板工作。模具芯具有用于将突出元件（尤其是攀岩铁）从内部粘合到待形成的混凝土部件中以及在成型过程中固定的装配装置。除了芯部段之外，安装装置具有用于每个爬铁的壳体，与其相关联的夹紧装置以及所有这些共同的夹紧驱动装置。与这些部件一起，芯部分可拆卸地且可交换地安装在模芯的其余部分上，从而可以将其与水平平移驱动器联接或分离。因此，在保持模芯的其余部分的同时，可以将芯部段更换成不同的芯部。因此，单个模芯的投资成本大大降低。

摘要： An apparatus is disclosed for centering a reinforcing mesh which is in a pipe or conduit form for manufacturing reinforced concrete pipe or conduit. In order to automatically center the reinforcing mesh in a simple and reliable fashion, a plurality of mesh centering units are provided which are distributed at spaced intervals around the perimeter of the form. Each of these units comprises at least one radially outwardly extending member which penetrates through a receiving slot into the form to a depth which is adjustable depending on the external diameter of the reinforcing mesh. When the concrete introduced into the form is compacted, the member can be retracted to an inactive position from the operating position, in which it biases against the centered mesh.

摘要： A hard outer member generally centered on an axis and having a concave inner surface is injection molded of a relatively hard synthetic resin to have on its inner surface at one end a recess formed with a radially throughgoing passage. Parts of the mold in which this member is molded are then displaced before the resin has time to cure and another softer synthetic resin is injected through this radially throughgoing passage to form in the recess a relatively soft seal having a sprue extending through the passage. The seal therefore adheres in surface contact with the inner surface at the recess and the sprue further ensures excellent holding of the seal on the member.
