A system for attaching a flexible expansion joint to the surface of a building such as the floor of a building. The system for attaching the joint is configured to secure the joint and provide, in effect, a form up to which a top coat of material such as concrete or asphalt can applied over an existing floor structure. The system provides a universal base unit upon which common extension units can be attached and stacked to vary the height of the form for the surface coat.

An acoustic attenuation device having two inserts made of acoustically absorbent material, the two inserts being different from each other and being separated from each other so as to delimit between them a longitudinal slot, each insert including a front surface intended to be oriented towards a space to be acoustically attenuated; and two support elements which are made of substantially acoustically impermeable material and which at least partially delimit an internal cavity in which the two inserts are disposed, each support element including a cover part partially covering the front surface of a respective insert such that the front surfaces of the two inserts are partially exposed, the two cover parts delimiting at least one passage opening which emerges into the internal cavity and which is located at least partially opposite the longitudinal slot so as to clear an access to the longitudinal slot.

A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.

A free-expansion deformation seam structure applied to a floor, including: a first base, a second base, a cover plate, a first telescopic component and a second telescopic component. A bottom of the cover plate is provided with a first connection part and a second connection part, one end of the first telescopic component is clamped in the first clamping groove in the first base, the other end thereof is fixedly connected to the first connection part, one end of the second telescopic component is clamped in the second clamping groove in the second base, the other end thereof is fixedly connected to the second connection part, and the first telescopic component and the second telescopic component are capable of expanding and contracting in the horizontal direction of the expansion seam to drive the cover plate to slide on the first base and the second base.

A barrier strip for sealing a joint of a building structure to inhibit transmission of a fluid through the joint. The building structure has flooring and a wall including wall elements. The barrier strip comprises a first side of a first shape, corresponding to the profile of the flooring, and a second side of a second shape, being complementary to a profile of the wall element. The barrier strip is located intermediate to the flooring and the wall element with the first side of the barrier strip in contact with a part of the flooring and the second side is in alignment with the wall element to cooperatively engage with the profile of the wall element. The barrier strip seals the joint between the flooring and the wall element to inhibit the transmission of the fluid through the joint.

Tiles 21 and 22 are laid up with other tiles in the usual way at and along the joint 18, the joint 18 comprises a female strip 23 and a male strip 24 each of which have fastening flanges 25 and 26 and respective 90? walls 27 and 28. A slot or rebate in the female section 29 holds an expandable seal, typically in this case a hydrophilic seal. The female part and the male parts are assembled for relative movement so that a small gap perhaps 2 mm at 31 may be accommodated while the the upper plate section 23 still provides a contiguous coplanar link between the parts.

An expansion joint profile system for producing an expansion joint in the manufacture of a rigid floor covering includes a profile (1) comprising a first profile element (3) having a first support leg (5) provided for bearing on a substrate (18) and a first abutment leg (6) projecting upwardly therefrom. A second profile element (4) has a second abutment leg (6). A connection element (9) is formed in a ridge-like manner and extends in the longitudinal direction between the two profile elements (3, 4) and connects them to one another in the lower region. An insertion opening (10) is formed between the abutment legs and is open at the top and extends in the longitudinal direction (L). A sealing element (11) is formed in a T-shaped cross-section with a downwardly projecting insertion leg (12) for insertion into the insertion opening (10).

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.
