    摘要: A sleeve for forming a channel through a concrete slab is described herein. The sleeve includes a sleeve body with top and bottom ends extending along a longitudinal axis, wherein the top end is wider than the bottom end. The sleeve includes an attachment flange attached to the bottom end that extends laterally outward with respect to the longitudinal axis. The attachment flange may be secured to a concrete form. An alternative sleeve has an attachment mechanism protruding from the first end of the sleeve body for facilitating the attachment of the sleeve body to a concrete form. In some embodiments, the sleeve can also include a removal mechanism disposed at the second end of the sleeve body to facilitate removal of the sleeve body from the concrete slab. Various sleeve configurations are described, some of which are reusable and some of which are one-time use only.

    摘要: The disclosure is directed to a method and system for securing a shoring deck to a column. The method includes providing a first beam bracing against a column, wherein the first beam is disposed at a first longitudinal axis that is perpendicular to a long axis of the column. The method includes coupling the first beam to first and second deck beams of a plurality of deck beams of a shoring deck. The method also includes providing a second beam bracing against the column and coupling the second beam to third and fourth deck beams of the plurality of deck beams. The method further includes positioning the first and second beams with respect to the column such that respective first and second longitudinal axes through the respective first and second beams are aligned at an acute angle with respect to each other.

    摘要: A pass-through head assembly is provided. The pass-through head assembly may include a central shaft, a plurality of support bars, a seat, and a seat support plate. The central shaft may extend between a first end plate and a second end plate. Each end plate may define an aperture that aligns with an interior cavity of the central shaft. The plurality of support bars may extend from the central shaft and the second end plate. The seat and seat support plate may each be circumferentially disposed about the central shaft and define apertures that are sized to allow the seat and the seat support plate to pass over the central shaft and the plurality of support bars. The seat may be configured to support one or more beams. The seat support plate may be disposed between the seat and the second end plate.

    摘要: A shoring system for concrete slabs is disclosed. One such system includes a drop head with a beam support member which can be moved between lower and upper positions, and a wedge member which locks the beam support member in its upper position by a translational, sliding movement thereof. Wedge member includes a narrower toe portion and a wider heel portion, and the toe portion is insertable past corresponding engagement surfaces on the post of the drop head, to support the wedge member in its upper position. The beam support member has a lower surface engaged by the wedge member and such lower surface is longitudinally spaced from the upper surface of the beam support member, so that there is open space between the wedge member and the bottom surfaces of beam supported by the upper surface of the beam support member.

    摘要: Apparatus is provided for vertically-extending construction column and horizontal construction beam assembly having beam-reference portion. Apparatus includes prop head assembly configured to be fixedly connected to vertically-extending construction column, and also configured to support horizontal construction beam assembly once the prop head assembly is fixedly connected to vertically-extending construction column. Prop head assembly includes first beam-locating feature and second beam-locating feature. First beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature configured to selectively receive, at least in part, the beam-reference portion. Second beam-locating feature is also configured to receive beam-reference portion once the beam-reference portion is inadvertently displaced away from first beam-locating feature and from vertically-extending construction column and toward second beam-locating feature.

    摘要: The invention relates to a ceiling table (10) for a partial formwork of a concrete ceiling. The ceiling table (10) has at least one formwork element, in particular multiple formwork elements, which can be assembled on a lower frame (16) of the ceiling table (10) in a nondestructive manner and which can be disassembled from the lower frame (16). The ceiling table (10) has a support skeleton (14) on which at least one formwork element, in particular multiple formwork elements, is/are arranged. The support skeleton (14) can have multiple braces which can be connected together and separated from one another in a nondestructive manner. The support skeleton preferably has a pair of main supports, in particular parallel running main supports, on which a pair of edge supports and at least one central support that is arranged between the edge supports are arranged. The edge supports and the central support run preferably parallel to one another. The invention further relates to a ceiling formwork comprising such a ceiling table (10).
