The present invention relates to bars for load transmission, which if anchored in concrete slabs create a support between them, forming semi-rigid joints and accompanying the differential settlements of the foundation bed, as a result of the rotation in the vertical direction about the joint axis, and transmitting the load from a slab to the other, ensuring a perfect leveling of the surface thereof when occurring elastic movements of the foundations, and allowing the possibility of removing the slabs at any time and reuse them again, due to the telescopic effect of the bars. The telescopic function of the bar which allows its support between slabs created a new possibility of obtaining prefabricated floorings of easy manufacture and assembly in situ, creating a new concept in the construction of roads, ports, airports, railways, industrial areas, etc., which distinguishes the present invention from the closest state of the art.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

An embodiment is directed to a duct coupler for joining two segments of conduit. The duct coupler includes a coupler body. The coupler body is generally tubular and has an inner diameter generally corresponding to the outer diameter of a section of conduit measured at an annular locking rib positioned on the section of conduit. The duct coupler further includes one or more protrusions formed on the interior surface of the coupler body. Each protrusion is generally wedge shaped. The one or more protrusions are positioned to engage with at least one annular locking rib to retain the section of conduit within the coupler body. The duct coupler further includes a body gasket. The body gasket is generally tubular and positioned on the interior surface of the coupler body. The body gasket is positioned to form a seal between the inner wall of the coupler body and the outer wall of the section of conduit.

A stirrup module includes an outer stirrup set, an upper-opening stirrup set having an upper opening and provided in an opening of the outer stirrup of the outer stirrup set, and a lower-opening stirrup set having a lower opening and provided in the opening of the outer stirrup of the outer stirrup set. Wherein the upper opening and the opening of the outer stirrup are oriented in the same direction, the lower opening and the upper opening are in opposite directions to each other. Wherein the upper-opening stirrup set has a first bottom of stirrup opposite to the upper opening, and the first bottom of stirrup corresponds to the position of the lower opening; the lower-opening stirrup set has a second bottom rib opposite to the lower opening, and the second bottom rib corresponds to the position of the upper opening.

A hanger bracket for mounting a skewed beam at a junction of two adjacent beams includes a supporting section configured to support the skewed beam. Fixing flanges are substantially perpendicular to the supporting section and are configured for attaching the bracket to the adjacent beams. The fixing flanges lie in different planes to each other. Reinforcing faces are located between the supporting section and each of the fixing flanges. The reinforcing faces are inclined relative to the supporting section and fixing flanges. The hanger bracket includes holes in the supporting section or reinforcing faces configured to secure the skewed beam to the hanger bracket.

Reinforcing is disclosed comprising a reinforcing bar extending along a portion of the length of the reinforcing and a termination extending along an end portion of the reinforcing. The termination may have a body extending in a longitudinal direction and a lateral engagement face formed on the body. The engagement face may incorporate locking formations thereon arranged to interfit with a complementary shaped termination to form an interlock arranged to accommodate loading applied in the longitudinal direction.

A cementitious composite material for in-situ hydration includes a first layer having a nonwoven configuration and a cementitious material disposed within the first layer. The first layer has a first side and an opposing second side, and the first layer includes a plurality of discrete nodes spaced relative to one another along a first direction and a second direction. The cementitious composite material further includes a second layer disposed along the first side of the first layer and a third layer disposed along the opposing second side of the first layer and configured to prevent at least a portion of the plurality of cementitious particles from migrating out of the first layer. The cementitious material includes a plurality of cementitious particles, the first layer and the second layer include flexible materials, and the second layer is coupled to the first layer at the plurality of discrete nodes.
