摘要： A can plaza assembly is configured to provide electrical distribution at a location. The can plaza has a box, further comprising a side wall opening and joined to a lid. A plurality of cans is arranged inside the can plaza. Conduits project outward from each can. Fittings are joined to the conduit and extend through the side wall opening of the box. Foam fills the box around the cans and the conduits, such that the foam does not completely cover the cans. Rebar is arranged twelve inches on center each way from the cans on top of the foam. Concrete fills upon the rebar and foam up to an upper edge of the can. Electrical wires are routed through the conduits and cans provide the electrical distribution at the location.

摘要： A bracket holds a rigid or flexible tube during the pouring of a concrete slab. The bracket has a base and a housing connected to the base. The tube curves around a first tube support on the housing before passing through an opening in the bottom of the housing. The tube and any members inside the tube are cut off so they end inside the housing and are then covered by a housing cap. The base is fastened to a form for the concrete slab. The height of the housing relative to the base is adjusted to place the cap at the planned surface of the concrete slab. After the concrete slab is formed the cap is removed and the cut members inside the housing are connected to other members or devices.

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： The invention relates to a feed-through member (1) which is to be mounted in a wall element or floor element and comprises a tube element (2) that includes a first (23) and a second (24) tube element section. Said tube element sections (23, 24) can be moved relative to one another in the conducting direction (21) in such a way that the length of the tube element (2) is adjustable, a blocking mechanism (26, 32; 51, 61) being provided which at least partly prevents the tube element sections (23, 24) from moving when same are in the relative positions.

摘要： The present invention provides a floor through-passage molding apparatus adapted for a floor construction, which comprises a forming sleeve, a first covering plate assembly, a second covering plate assembly and a plurality of retaining assemblies. Said forming sleeve has a sleeve wall defining a hollow channel, a first opening and a second opening. Said first and second covering plate assemblies are respectively disposed on the first and second openings of said forming sleeve. Said plurality of retaining assemblies passes through the hollow channel of said forming sleeve, and are respectively retained with the first and second covering plate assemblies by a plurality of corresponding retaining holes formed on said first and second covering plate assemblies, wherein positions of the plurality of corresponding retaining holes distributed on said first covering plate assembly or said second covering plate assembly jointly define at least one plane.

摘要： A cast iron pipe sleeve is provided at each end with a tight-fitting metal disk. A threaded steel rod is screwed into a nut welded in the center of the inside face of a solid disk. The disk rests against the outer edge of the sleeve and the rod extends through the interior of the sleeve and out through a hole in the center of the opposite disc and further through a hole in one of the form walls. A long bar or channel provided with a center hole is placed over the end of the rod and across two external studs on the form wall. As a nut is tightened onto the end of the rod against the channel, the sleeve is drawn securely and squarely against the form wall. After the other form wall is secured in place tightly against the solid disc end of the sleeve, the concrete is poured and cured, the exterior nut is removed, the form walls are removed, and the discs and rod are removed to be reused. The sleeve remains cast in the concrete as a cylindrical passage through the thickness of the concrete for pipes. One alternate embodiment provides an interior disc bolted within the sleeve. Another embodiment provides a sleeve extending completely through the form with a bent bar bolted to the form a distance of two sides of the sleeve.
摘要翻译： 每个端部都设有铸铁管套，配有紧密的金属盘。 将螺纹钢棒拧入焊接在固体盘内表面中心的螺母。 光盘靠在套筒的外边缘上，杆延伸穿过套筒的内部并穿过相对盘的中心的孔，并进一步通过一个形式的壁中的一个孔。 设置有中心孔的长条或通道放置在杆的端部上并且穿过成形壁上的两个外部螺柱。 当螺母紧固到杆的端部靠在通道上时，套筒被牢固地平直地拉到形成壁上。 在另一个形式的壁紧紧地固定在套筒的固体盘端上之后，混凝土被浇注并固化，除去外部螺母，去除形状的壁，并且将盘和杆移除以重复使用。 套筒保持浇注在混凝土中作为圆柱形通道穿过管道的混凝土厚度。 一个替代实施例提供一种螺栓连接在套筒内的内部盘。 另一个实施例提供一种完全延伸穿过该形状的套筒，其中弯曲的杆被螺栓连接成套筒两侧的距离。
