A tie shear connector for use with insulating composite panel structures having a first structure layer and second structure layer, comprising an elongated body having an interior cavity passage formed therethrough from at least one end, and at least one aperture configured to enable the flow of a fluidic hardenable material into a portion of the interior cavity passage. The tie shear connector can also comprise at least on placement pin to aid in depth penetration of the tie shear connector.

A concrete surface with a cold joint, dowel slip system and method for forming that surface are provided. Baseplates having tubular projections are fastened to at least one first form using fasteners extending part way into the first form, with the first form forming part of a periphery of a first concrete slab. When the first form is removed, the baseplates, projections and fasteners remain embedded in the first concrete slab. Slip dowels are inserted into the tubular projections and a second concrete is poured adjoining the first concrete slab, with the second concrete embedding the slip dowels, backplates and projecting distal ends of the fasteners and forming a cold joint.

A mechanical connector for securing a dowel rod to a frame of a dowel bar assembly as well as a dowel bar assembly are detailed. Each embodiment of the mechanical connector includes a portion to receive the dowel bar. A second portion of the mechanical connector engages the frame of the dowel bar assembly. A third portion of the mechanical connector engages a separate part of the frame further stabilizing the mechanical connector and frame.

A floor dowel sleeve has a body portion with a top wall, a bottom wall, two side walls, and an end wall that together to surround an interior cavity. The interior cavity is configured to receive a dowel plate at an opening in the body portion opposite the end wall. Spacing elements are disposed at each of the two side walls and are configured to interface with opposing edges of the dowel plate to provide a space between the dowel plate and interior surfaces of the two side walls. The spacing elements each have a pair of legs that integrally protrude from the side wall into the interior cavity and interconnect to form a spacing chamber. The spacing elements are each configured to flex into the spacing chamber upon lateral horizontal movement of the dowel plate within the interior cavity.

An enamel coated steel dowel bar and a method of manufacturing said enamel coated steel dowel bar for use in joining together and stabilizing concrete slabs by drilling a first hole at a first end of an axis of the dowel bar, drilling a second hole at a second end of the axis of the dowel bar, configuring a first end plug into the first hole of the dowel bar, configuring a second end plug into the second hole of the dowel bar, attaching a first end cap over the first end plug and the first hole, and attaching a second end cap over the second end plug and the second hole, wherein a pin is removably attached to the first hole and the second hole to mount the dowel bar during an enamel coating process and wherein the dowel bar is slidably attached to the first end cap and the second end cap.

A floor dowel sleeve is provided that includes a rectangular-shaped body portion having a cavity that is configured to receive a dowel plate that spans across a seam between concrete slabs. A pair of break-away interior walls extend within the cavity from the opening to the end wall of the sleeve. The interior walls extend between two opposing (horizontal) walls of the exterior side walls and are continuously spaced from the other two opposing (vertical) walls of the exterior side walls. The body portion is configured to receive the dowel plate in the cavity between the break-away interior walls, where the break-away interior walls are configured to at least partially break-away from the exterior side walls upon lateral horizontal movement of the dowel plate within the cavity.

Various embodiments of the present disclosure provide a cast-in-place concrete slab load transfer apparatus and method of manufacturing same. In various embodiments, the concrete slab load transfer apparatus includes a plurality of load transfer dowels each having a top surface and a bottom surface, a basket supporting the load transfer dowels, and a plurality of welds including a plurality of breakable welds connecting the bottom surfaces of the load transfer dowels to the basket.

A floor dowel sleeve is provided that includes a rectangular-shaped body portion having a cavity that is configured to receive a dowel plate that spans across a seam between concrete slabs. A pair of break-away interior walls extend within the cavity from the opening to the end wall of the sleeve. The interior walls extend between two opposing (horizontal) walls of the exterior side walls and are continuously spaced from the other two opposing (vertical) walls of the exterior side walls. The body portion is configured to receive the dowel plate in the cavity between the break-away interior walls, where the break-away interior walls are configured to at least partially break-away from the exterior side walls upon lateral horizontal movement of the dowel plate within the cavity.

Various embodiments of the present disclosure provide a joint edge assembly and method of positioning and installing joint edge assembly for adjacent concrete slabs. The method includes positioning the joint edge assembly in an offset position from the joint. The method of various embodiments also includes using a plurality of height adjusters or plates fixed to the slab engagement surface of the one of the joint edge members to adjust or assist in adjusting the height of the joint edge assembly relative to the formwork and relative to the plane of the top surfaces of the concrete slabs.

Presented herein is a connector forming a joint between first and second surfaces. The connector includes a hollow male member embedded in a first surface. The male member has open ended protrusion extending therefrom. A hollow female member to be embedded in second surface. The female member has a mating opening for receiving the protrusion and a flexible sealing means for forming a fluid tight seal between the female and male members. When installed, a tendon forms part of the first surface and extends through protrusion into female member. Prior to grouting, movement of the tendon during settling of first surface is facilitated by the male and female member, without breaking the fluid tight seal formed by flexible sealing means. Also presented is a method of forming a joint between a vertical surface and a horizontal surface.
