A system for sealing a space defined between a modular wall and a permanent structure includes a sealing material connected to the permanent structure and the modular wall and spanning the space defined therebetween. The sealing material is configured to transform from an expanded state to a recovered state in response to a stimulus to form a seal. The stimulus can be, for example, heat, whereby heating the sealing material at or above the transition temperature for the sealing material causes the sealing material to transition from the expanded state to the recovered state.

An approved dynamic construction is used for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction. The exterior wall construction includes a curtain wall configuration defined by an interior wall glass surface including one or more aluminum framing members, where the vision glass extends to the finished floor level below. The dynamic, thermally insulating and sealing system includes a first element for receiving the insulating elements, and is positioned in the zero spandrel area of a glass curtain wall construction including only vision glass, to maintain thermally insulating and sealing of the safing slot during exposure to fire and heat as well as movement in order to maintain a complete seal extending across the safing slot.

To provide a surface treatment device having improved treatment quality of surface treatment using a foamable material, a surface treatment device includes, a moving body which can move along a surface of a processed object, a first spray device which is provided on the moving body and sprays a first material Sf having foamability on the surface of the processed object, and a second spray device which is provided on the moving body and sprays a second material Sc for covering the surface of the first material on a area of the surface of the processed object after spraying the first material from the first spray device and the first material is foamed.

An approved dynamic construction is used for effectively thermally insulating and sealing of a sating slat between a floor of a building and an exterior wall construction. The exterior wall construction includes a curtain wall configuration defined by an interior wall glass surface, including one or more aluminum framing members. In particular, a process is useful for assembling a fireproof system within a stick build exterior dynamic curtain wall façade, which includes glass, especially vision glass extending to the finished floor level below.

An approved dynamic construction is used for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction, wherein the exterior wall construction includes a curtain wall configuration defined by an interior wall glass surface including one or more aluminum framing members, wherein the vision glass extends to the finished floor level below. The dynamic, thermally insulating and sealing system includes a first element for receiving the insulating elements and positioned in the zero spandrel area of a glass curtain wall construction including only vision glass to maintain thermally insulating and sealing of the safing slot during exposure to fire and heat as well as movement in order to maintain a complete seal extending across the safing slot.

A vertical seal for use with a first and second exterior panels, the vertical seal including a first pair of opposed sides and a second pair of opposed sides. The second pair of opposed sides extend between the first pair of opposed sides, and the second pair of opposed sides have bends formed therein such that first pair of opposed sides are moveable towards each other under pressure. When the vertical seal is positioned between the first and second exterior panels and a seal is formed therebetween. An exterior wall system includes a plurality of exterior panels, a plurality of vertical seals operably connected between horizontally adjacent exterior panels and a plurality of horizontal seals between vertically adjacent panels.

A box assembly includes a box, a door, an opener, and an insulation material. The box is configured to be installed on a curtain wall. The door encloses an interior space of the box. The opener is configured to open the door. The insulation material is in a compressed state in the interior space when the door is closed. The insulation material is configured to transition to an uncompressed state when the opener opens the door. When the door is opened, the insulation material at least partially extends from the interior space into a safing slot adjacent the curtain wall when the box is in an installed state and the door is opened.

A structure-lining apparatus for lining one or more surfaces of a structure formed from curable material cast in a form. The apparatus comprises a plurality of panels. The panels are connected at their respective edges in an edge-to-edge connection to provide a structure-lining surface. A plurality of anchoring components project from the panels into the liquid material during fabrication of the structure. The anchoring components each comprise one or more anchoring features which are encased in the material as the material solidifies to thereby bond the anchoring components to the structure. The plurality of anchoring components comprises one or more connector-type anchoring components for connecting to corresponding connector-type anchoring components on adjacent edges of a corresponding edge-adjacent panel to connect the edge-adjacent panels in an edge-adjacent relationship. The apparatus comprises one or more breakaway components on at least one of the plurality of panels.

A waterstop assembly for use as embedded components in at least a pair of adjacent concrete slabs, defining elongated first and second waterstop panels including a main body sheet to which is mounted by coextrusion or insertion to both of its opposite top and bottom ends a soft expansible flange made from hydrophilic thermoplastic material. Each hydrophilic soft flange has such an expansion capability as to provide strong radially outward pressure applied by the soft flange against the adjacent concrete slabs, thus providing watertight interconnection therebetween. A welding block is taken in sandwich between overlapping transitional end portions of the first and second waterstop panels. Integral ridge and groove connectors interconnect the welding block with the waterstop panels. Resistance wires connected at one end to an electric power source fuse the welding block and the first and second waterstop panels, wherein a watertight joint is formed therebetween. An upright steel post is mounted spacedly parallel to a corresponding one of first and second waterstop panels, and a transverse anchor arm transversely spacedly retaining waterstop panel in upright operational condition parallel to the steel post before and during first concrete pour.
