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

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.

The invention pertains generally to a low-pressure (100-250 psi) process of seaming adjacent seams of artificial turf using a one-component or a two-component polyurethane adhesive using an apparatus which employs a payoff spool of base material in the front of the apparatus and an activation trigger adjacent the handle to begin the application of polyurethane spray foam adhesive by connectivity between the application trigger and the foam spray gun trigger.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, and a support foot for supporting the system relative to a ground surface, wherein the first part has a pair of vertically opposed longitudinal rails, and the support foot has an engagement formation which has an unlocked orientation for inserting the formation between the opposed rails to abut against the first part and a rotated, locked orientation wherein the formation is locked by the rails against lateral withdrawal from the first part.

For the construction of synthetic grass playing fields, a plurality of panels (1, 1′, 1″) are manufactured by injection molding and stacked in groups (50). Each stacked group (50) is placed on a distributor vehicle (90) moved along a covering direction (Z), so that the panels (1) which compose the group (50) are able to rotate relative to each other with respect to a main direction (X) orthogonal to the covering direction (Z), so that a row of panels is constructed.

A crane mat having first and second side beams or boards; a core structure made of pine or other softwoods, eucalyptus, solid plastic or elastomeric members, or hollow thermoplastic, thermosetting plastic or elastomeric members that optionally include a filler or internal reinforcing structure; external components including an upper and/or lower layers of one or more elongated members to protect the core structure, and a plurality of joining members that attach the outer side members to the core structure. Another crane mat can be made of just the solid plastic or elastomeric members, or hollow thermoplastic, thermosetting plastic or elastomeric members that each include a plurality of spaced lateral apertures passing therethrough; and joining members that include a rod that passes through the aligned lateral apertures to hold the members together in the mat. These crane mats may also include lifting elements of the types described herein.
