A flanged conduit support for forming openings in a poured concrete structure. The flanged conduit support includes a flange and a hub with a socket. A ganging means on the flanged conduit support enables the joining and locking of two or more supports together in a spaced relationship. The ganging means includes a male snap member with a tab and a tapered end and the female snap member includes a receiving slot. The flanged conduit support provides a means for rapidly securing a first end of conduit to a form and capping the opposite ends of the conduit to prevent the entry of concrete during the concrete pour. A removable cap may be removed after the concrete cures to provide one or more open pathways for running electrical cables through the horizontal floors or vertical walls.

A keywell form retention assembly includes post that having a bottom end and a top end. The post has a front side and a back side. A plurality of mounting holes extends through the front and back sides. The mounting holes receive fasteners to mount the post to a cement form. A sleeve is attached to the top end of the post. An arm has a first end and a second end. The arm extends through the sleeve and is movable forward or rearward through the sleeve. A leg is attached to and extends downwardly from the arm adjacent to the first end. An anchor plate is attached to the leg. The anchor plate has a mounting aperture extending therethrough to receive a coupler to engage a panel. The anchor plate retains the panel such that that panel abuts and stabilizes a keyway form.

Disclosed herein is a connecting device for connecting an assembly of adjacent panels, wherein the connecting device has a body comprising at least two portions, each portion having means for anchoring the connecting device into a respective recess in one of the panels of the assembly, which, when the panels are so assembled, the connecting device is receivable in a void formed by the recesses of the panels thereby joining the panels together and wherein the connecting device is configured to selectively connect an assembly of two, three or more panels.

A drain has a cup with a fluid outlet to be connected to a conduit, wherein the cup accommodates a water trap. The cup has an axial channel along the circumference, the channel is open upwards and limited by a bottom, a channel wall and a cup wall. The drain further has a circumferential drain wall adapted to fit into the channel, whereby the drain wall is arranged axially movable in the channel, a casting framework arranged releasable around the outer circumference of the drain wall, the framework has a radial extension, and the drain wall has an outward radial flange at an upper end, the radial extension of the flange is equal or less than the radial extension of the framework. A method and a kit of parts for installing such a drain are also disclosed.

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.

A first firestop device and a second firestop device, each comprising a housing. The housing of the first firestop device has a connection side with a plurality of connection elements and the housing of the second firestop device has a complementary side with a complementary element. The connection elements are each arranged at a different location on the connection side of the housing of the first firestop device, so that a position of the first firestop device relative to the second firestop device, when the connection side of the housing of the first firestop device is interlocked with the complementary side of the housing of the second firestop device, is selectable by selecting which of the connection elements of the first firestop device is connected to the complementary element of the second firestop device.

A blockout apparatus, for use in creating passageways through prefabricated concrete structural members, has at least one hanger members integrally molded with the blockout apparatus as a dome projecting above the body of the blockout member that can be used to support conduits inserted through the passageway. A wedge nut can be inserted into the hanger members and twisted to lock the wedge nut in place. The wedge nut can be installed before the blockout apparatus is positioned within the concrete form for the manufacture of the prefabricated concrete structural member, or after the concrete structural member has been formed. Typical usage of the blockout apparatus is to create passageways through the T-Beam of Double-T panels so that conduits can pass through the void corresponding to the blockout apparatus. Mounting devices that support the conduits can be engaged with the wedge nut and provide support for one or multiple conduits.

A sleeve assembly is provided comprising an inner tubular member and at least one outer sleeve that receives at least a portion of the inner tubular member. The outer sleeve may longitudinally telescope with the inner tubular member to move between a non-expanded position and at least one expanded position. In some embodiments, the inner tubular member comprises a first locking component and the at least one outer sleeve comprises a second locking component that interlocks with the first locking component to secure the outer sleeve in the non-expanded position and/or at least one expanded position. Related methods for making a sleeve assembly are also provided.
