摘要： This disclosure describes devices and methods for forming voids in or adjacent concrete structures. In some embodiments, a device may include a structure. The structure may be substantially planar. The structure may include a plurality of channels extending therefrom. In some embodiments, the channels are closed at a first end distal from the structure. In some embodiments, the channels are open at a second end proximal to the structure. In some embodiments, the device may be formed from a molded pulp. The molded pulp may be configured to inhibit penetration of water. In some embodiments, the device may be configured to substantially support poured concrete during at least a portion of a curing process of the poured concrete.

摘要： A tank seal for use in cast concrete walls has a generally cylindrical main body portion with a stepped outside wall having first axially-extending portion, a second axially-extending portion having an outermost diameter less than an outermost diameter of the first axially-extending portion, and a radial ledge or step separating the first and second axially-extending portions. A wiper blade portion extends radially inwardly of the stepped outside wall, from an end of the second axially-extending portion opposite the radial ledge, terminating at a third end. A circular membrane or web extends across the third end, including at least one annular groove therein to facilitate removal of at least one circular portion of the web. The radial ledge collapses and the first axially-extending portion puckers in response to compressive force exerted on the tank seal in an axial direction, reducing the axial length of the tank seal.

摘要： A reusable and adjustable arch-forming assembly employing a flexible sheet for placing construction materials thereon for the purpose of constructing an arch. The assembly has a center pole with a vertex support and two cross beams mounted by their proximal ends in slidable members engaged around the center pole. Each cross beam has an arch end support at its distal end. An auxiliary support mechanism aids in setting the inclination of the cross beams with respect to the center pole and provides mechanical support for the cross beams at the set inclination. The arch is defined by a curvature assumed by the flexible sheet between the vertex support and the two end support mechanisms. Supplementary arrangements of the assembly permit one to prepare any desired arch structure by adjusting the curvature of the flexible sheet.
摘要翻译： 一种可重复使用和可调节的拱形成组件，其采用柔性片材将建筑材料放置在其上用于构造拱门。 该组件具有带有顶点支撑的中心极，并且两个横梁通过其近端安装在可围绕中心极的可滑动构件中。 每个横梁在其远端具有拱形端部支撑。 辅助支撑机构有助于设计横梁相对于中心极的倾斜，并且在设定的倾斜度下为横梁提供机械支撑。 拱形由由顶部支撑件和两个端部支撑机构之间的柔性片材所假定的曲率限定。 组装的补充布置允许通过调节柔性片的曲率来制备任何所需的拱形结构。

摘要： A formwork for a draft tube which includes ganged precast forms, each precast form corresponding to a curved segment of the draft tube. The precast forms are molded with continuous side plates extending thereabout and anchored in the precast concrete form and projecting beyond the surface opposite to the contact surface to provide a flange. A fastening means for attaching adjacent forms with a space therebetween to allow for stripping. A method includes determining the outline of the inner surface of the draft tube and dividing it into segments and preparing molds to make precast forms corresponding to each segment. The precast forms are assembled and shored to provide the draft tube ganged formwork, and concrete is poured about the draft tube formwork and is cured. The precast forms are stripped from the set concrete structure and reused in another draft tube formwork.

摘要： The oil and gas well pad foundation form system isolates a concrete pour from the well head and provides blockouts for piping installation. The system can be removed after concrete pour and set up and reused countless times. The system is provided in different sizes with blockouts in varying locations as desired. Multiple well heads can be prepared for within a given cellar, simultaneously.

摘要： A fitting for attaching ENT tubing to a concrete form has an inverted cup-like configuration with a bottom opening and an internal cavity within a fitting wall. A flange extends outwardly from the fitting wall around the bottom opening and has fastener-receiving holes for attaching the fitting to a plane surface of a concrete form. A socket extends through the fitting wall into the cavity for receiving an end portion of an ENT tube. The socket has a plurality of circumferentially-spaced resilient fingers that are inclined inwardly toward the socket axis for gripping an ENT tube. A pair of opposite fingers have teeth that are receivable in an annular groove in an end portion of a corrugated ENT tube. The teeth have rounded ends to facilitate ratcheting movement of the ENT tube end portion both into and out of the socket.
