A concrete dowel placement system and methods for making the same. The system allows for accurate and easy substantially-parallel or parallel placement of slip dowels within sections of concrete so that adjacent sections of concrete may be allowed to undergo thermal expansion and contraction while remaining in a common plane without cracking or faulting. The system includes a coupler and a sheath. The sheath is configured to be slidably extensible over the coupler and may be held to the coupler by friction. An outer surface of the sheath may be textured. Additionally, a method of constructing the concrete dowel placement system includes extruding material to form two tubes of different sizes. The tubes are then attached to each other, then material is extruded or injection molded to form a sheath. Alternatively, construction may include extruding material to form a tube, then removing some of the material from the tube in order to form a coupler.

The invention relates to a load-transferring connecting element (1) for establishing a connection between a first building element and a second building element. The load-transferring connecting element is adapted for transfer of forces between the two building elements. The load-transferring connecting element (1) comprises an elongated box-shaped main body (24), wherein a first end portion (3) of the load-transferring connecting element (1) is arranged for attachment into the first building element with a remaining second end portion (4) of the load-transferring connecting element (1) positioned so that it projects from the first building element. The second end portion (4) is adapted for being received in a cavity (13) arranged in the second building element, and is provided with an attachment area (5) for attaching lifting equipment (8) for handling the first building element.

A method and an arrangement for supporting a first floor element at a beam and a beam. The beam is provided with a supporting flange section configured to support the first floor element. The method includes supporting the first floor element on the supporting flange section so that a first space is formed between the first floor element and the beam, providing elongated transverse fittings in the beam, providing transverse reinforcements to extend between the beam and the first floor element. The elongated transverse fitting have a first free end at the first lateral side of the beam, and a first protective element is connected to the first free end of the elongated transverse fitting outside the web section of the beam.

A connector and a method of manufacturing a connector are provided for joining a precast concrete structure and a support structure such as a floor joist. An attachment member of the connector is assembled in a manner that allows forces to be transferred through a protrusion and aperture connection, which reduces the forces transferred through welded joints. As a result, the attachment member requires less welding and saves time and costs when installing the connector. In some embodiments, a support is secured to a horizontal plate which increases the rigidity of the horizontal plate and the ability of the horizontal plate to transfer forces from a support structure to a precast concrete structure.

Adjacent concrete wall panels are connected at the vertical joint by a shear connector structure that includes a metal connector angle embedded in a corner portion of one of the panels, and one or more threaded nuts or studs are welded to a flange of the angle. A metal shear connector plate has a hole for each threaded nut or stud and elongated holes or slots for the other concrete panel. After the panels are erected and positioned, the connector plate is bolted to the studs and self-tapping concrete anchor screws are inserted into the slots and threaded into holes formed in the other panel. The studs are formed by machinery weld studs to form a bore with threads at the welded end of each stud.

A concrete anchor assembly includes an anchor body including a rod portion and a head portion; the head portion extending laterally from said rod portion, the head portion including a threaded bore; and the rod portion including an internally threaded bore, the rod portion including an outside thread.

An anchor bolt fastener assembly with specialized connection capabilities and features for attaching building components to concrete slabs, walls, ceilings, and/or structural surfaces. Compression force can be established and maintained over time using a compression washer in combination with a specialized fastener stud that is designed to exploit the compression washer benefits. Methods of using exemplary embodiments include installing the anchor bolt fastener assembly relatively flush with the surface of the concrete slurry by direct insertion in the slurry using a specialized threaded anchor bolt float. Once the slurry hardens, the anchor bolt and anchor bolt float embedded in the concrete slurry cooperate with the specialized fastener stud to secure the building component to the concrete.

An anchor assembly for being embedded in concrete includes a metal plate including an opening, the metal plate including a top surface and bottom surface; the opening including a wall extending from the top surface or the bottom surface; and a threaded rod operably attached to the metal plate.

An anchor assembly (10) comprises an anchor (12) comprising a body (15) defining a cavity (16). The anchor (12) further comprises a reinforcing member (18) extending through the cavity (16) and outwardly from the body (15). The anchor assembly (10) further includes an insertion device (14) insertable into the cavity (16). The insertion device (14) comprises a securing member (49) movable between securing and non-securing positions. When the movable securing member (49) is in the securing position in the cavity (16), the securing member (49) can engage the reinforcing member (18) to secure the insertion device (14) to the anchor (12).
