Shear force anchor for transmitting shear forces transversely to the longitudinal direction of a structural element within structural elements made primarily of concrete, comprising: a connection section for introducing at least one shear force into the shear force anchor which is connected to at least one load introduction section, which can be contacted to the structural element to transmit at least one force component in the direction of the shear force to be transmitted to the structural element. In order to transmit large shear forces while at the same time having a slim design of the structural element, the connection section is additionally spaced in the direction of the shear force to be transmitted from the load introduction section.

Various embodiments of the present disclosure provide a load transfer plate and a load transfer plate pocket that co-act to transfer vertical or substantially vertical loads from one concrete slab to an adjacent concrete slab in an enhanced manner by minimizing the air gaps in the concrete slab in which the load transfer plate pocket is positioned.

Various embodiments of the present disclosure provide a load transfer plate and load transfer plate pocket that co-act to transfer vertical or substantially vertical loads from one concrete slab to the adjacent slab in an enhanced manner by optimizing the positions of the load transfer plate relative to the adjacent concrete slabs for load transfers between the adjacent concrete slabs.

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.

Various embodiments of the present disclosure provide a cast-in-place concrete slab load transfer and slab connection apparatus and method of employing same.

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. 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 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.

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.
