An apparatus for connecting precast elements, wherein the apparatus includes a first part adapted for being cast into a first one of the precast elements, and the apparatus further includes a second part adapted for being cast into a second one of the precast elements, wherein the first part and the second part are arranged to receive a fastener for fastening the second precast element relative to the first precast element with the fastener crossing a joint between the precast elements at an angle to the joint.

The present application relates to a backer rod for sealing a void. The backer rod comprises an extruded polymer foam composed of crosslinked linear low density polyethylene and poly(ethylene-vinyl acetate) and contains an insecticide. Exemplar insecticides include termiticides such as bifenthrin, permethrin, deltamethrin, lambda-cyhalothrin, cypermethrin, alpha-cypermethrin, zeta-cypermethrin, tetramethrin, and cyfluthrin. The backer rod may be used as physical and chemical barrier to prevent the ingress of insects into a structure.

The sealing tape for sealing a joint comprises two foam strips of flexible foam, which are not formed as integral parts of each other, and which are arranged next to each other in the functional direction of the sealing tape. A film strip is arranged between the foam strips and is bonded to both foam strips. Adhesion sites between the film strips and the first foam strip are arranged only in an upper area of the first foam strip and in a lower area of the first foam strip, whereas, in an intermediate area between the upper area and the lower area of the first foam strip, the film strip is not adhesively bonded to the first foam strip.

There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, and at least two adhesion modifying zones disposed between the second major surface of the article and the first major surface of the liner, wherein both of a first and second adhesion modifying zones contact the first major surface of the liner, and wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided films made using these air and water barrier articles and building envelopes made using such films.

A joint-sealing element is useful for fireproof sealing of building-structure joints, especially for fireproof sealing of a joint between a first building part and a second building part, with a carrier element and a sealing profile disposed on this carrier element, wherein the disposed sealing profile contains an intumescent material.

The present invention relates to an acoustical and thermal decoupling system (10) in a form of a polymer tape that includes a closed-cell foam layer (12) having a front side and a reverse side, a pressure sensitive adhesive (14) coated on the reverse side of the closed-cell foam layer (12), and a release liner (16) covering the pressure sensitive adhesive (14) on the reverse side of the closed-cell foam layer (12). The acoustical and thermal decoupling system (10) may be installed directly to a structural member of a building by removing the release liner (16) from the reverse side of the closed-cell foam layer (12) and pressing the reverse side of the closed-cell foam layer (12) against the structural member, allowing the pressure sensitive adhesive (14) to bond the closed-cell foam layer (12) directly to the structural member.

A portable shelter with electromagnetic interference (EMI) protection includes a plurality of walls that define an interior space. The walls can be fixed or movable. An EMI protected edge connector joins at least two of the walls together. The EMI protected edge connector assembly can be fixed or hinged. The edge connector can include a metallic outer edge member with two legs and a separate metallic inner edge member with two legs to define an edge channel therebetween with: (i) the first outer leg and the first inner leg are arranged parallel and spaced-apart relative to each other; and (ii) the second outer leg and the second inner leg arranged parallel and spaced-apart relative to each other. The shelter walls can include an inner surface covered by a metallic foil inner layer. A first wall panel is received in a first portion of the edge channel with its metallic foil inner layer contacting the inner edge member and a second wall panel is received in a second portion of the edge channel with it metallic foil inner layer contacting the inner edge member.

A sealing tape roll comprises a sealing tape of flexible, compressible foam with at least one interior barrier layer. The sealing tape is wound up into the sealing tape roll in such a way that a top surface of one turn rests against a bottom surface of an adjacent turn of the sealing tape roll, and side surfaces of the sealing tape form end surfaces of the sealing tape roll. The sealing tape comprises a plurality of foam plies, which are arranged one above the other in a thickness direction between the bottom and top surfaces of the sealing tape. A barrier layer is between each pair of adjacent foam plies. The at least one barrier layer extends over at least 50% of the width of the sealing tape roll between the opposite end surfaces of the sealing tape roll and in a longitudinal direction of the sealing tape.

A sealing strip is prefabricated in the form of a sealing strip roll having a foam support which extends in a specified longitudinal direction, a width direction perpendicular to the longitudinal direction, and a thickness direction, wherein the foam support has a first primary surface defined by the longitudinal direction and the width direction and a second primary surface defined by the longitudinal direction and the width direction, the second primary surface lying opposite the first primary surface, and the foam support additionally has a first secondary surface defined by the longitudinal direction and the thickness direction and a second secondary surface defined by the longitudinal direction and the thickness direction. At least one secondary surface is coated with a sealing compound and/or at least one secondary surface is heat-treated.

An end seal member, which includes a contacting surface including a drainage cavity along the contacting surface. The end seal member also includes a seal material body including a central body protrusion projecting in a horizontal direction substantially orthogonal to the seal material body from an opposite face of the contacting surface. The end seal member also includes a first and second extending elements extending upward from the seal material body and a reinforcing metal plate within the seal material body. The contacting surface is substantially flat.
