An edge protection system including a first expandable armoured joint to protect a first joint extending in a first direction, a second expandable armoured joint to protect a second joint extending in a second direction and an intersection module including a cover plate located at an intersection of the first expandable armoured joint and the second expandable armoured joint.

Edge protectors are useful to be cast into the edges of concrete slabs to prevent spalling thereof after shrinkage has occurred and a gap has formed between adjacent slabs. An alternative edge protector (10) is described which comprises a first folded sheet having, in use, an upper (35) and a lower portion (25), the fold being on a first side of the first folded sheet and being alignable, in use, with the sidewall of the slab, the upper portion being planar and being arrangeable, in use, with its upper surface coplanar with the upper surface of the slab, the lower portion extending at least partially under the upper portion in a direction away from the fold, and continuing from the end of the lower portion in the same general direction, without any further folds or bends greater than 90 degrees, as an anchor portion (20) such that the anchor portion is arrangeable within the slab.

An edge protection system including a first expandable armoured joint to protect a first joint extending in a first direction, a second expandable armoured joint to protect a second joint extending in a second direction and an intersection module at an intersection of the first expandable armoured joint and the second expandable armoured joint, wherein the intersection module has an indicator to enable a user to ensure correct orientation of the intersection module.

An expansion joint cover for insertion in an expansion gap comprising a first frame section for attachment to a substrate at one side of the expansion gap, the first frame section having a flat surface; a second frame section for attachment to a substrate at an opposite side of the expansion gap, the second frame section having a first connector; a centre section configured to span the expansion gap and slide on the flat surface of the first frame section, the centre section having a second connector; and a linkage section configured to engage with the first and second connectors to connect the centre section to the second frame section, wherein the linkage section can pivot within the first and second connectors to allow movement of the centre section with respect to the second frame section.

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.

A transition construction for bridging a building joint between two component parts of a building with at least one cover element that at least partially covers the building joint. The cover element is attached to a component part of the building via an anchoring structure, wherein the anchoring structure is configured such that the at least one cover element is selectively supported.

A free movement, arris protection, construction joint has a pair of arris protection members formed complementarily from strips of sheet with a continuous trapezium wave form. A divider one of the members is typically 100 mm deep for a nominal 0.1 m deep slab. The other one is typically 50 mm deep. The members are of steel plate. The wave form is comprised of flanges extending in the length of the joint and of webs angled to the flanges and the length of the joint. The flanges are spaced on opposite sides of a mid-plane of the joint. The members are bolted together with flangible nylon bolts, with their top (in use) edges flush. Welded to the outer ones of the flanges are L strips having apertures in their flats extending from the flanges for anchoring the joint to its slabs.
