Insulation devices, methods and related construction techniques are provided. An exemplary device may include a body having a plurality of openings defining an openwork, to allow the passage of air therethrough when placed in contact with insulation material. The device may further include a plurality of spacer struts and/or spacing depressions fixedly attached to the body. The struts may be configured to maintain a predetermined distance between a first side of the insulation material and a building surface. The body and struts act together to define and maintain a space between the first side of the insulation material and the building surface, for example, for ventilation. The building surface can be the bottom face of a roof, an insulated attic floor, wall sheathing or a soundproofed demising wall, for example. The spacer device can be capable of being transported and stored together with, or as a separate item from, the insulation material, and can also be stored in nested layers. The device can also be stored in rolled form. The openwork of the device can additionally or alternatively include a sheet of entangled net filaments or other similar material.

A rugged noise muffler system is configured to substantially surround sound-emitting openings in a working unit or structure, to absorb sound emitted from the sound-emitting openings. A barrier component, formed as a housing, covers a sound emitting opening to inhibit sound from emanating from the housing, except at an open end of the housing. Each sound emitting opening in the working unit or structure requires a housing positioned over same. The housing includes a hood portion and an elongate portion that includes the open end of the housing. The inner surfaces of the hood portion and an elongate portion are lined with sound absorbing material. The emitted sound first enters the hood portion, is partially absorbed therein and any unabsorbed sound passes into and is substantially absorbed in the elongate portion as the sound travels towards the open end of the housing.

A method of assembling a building unit in accordance with a floor plan of a building using prefabricated components may include installing a first prefabricated floor panel in a first position of the building unit, the first floor panel being selected from a first plurality of prefabricated floor panels having a same first width; installing a second prefabricated floor panel in a second position of the building unit, the second floor panel being selected from a second plurality of prefabricated floor panels having a same second width; and installing a third prefabricated floor panel in a third position of the building unit, the third floor panel being selected from a third plurality of prefabricated floor panels. The floor panels in the third plurality of prefabricated floor panels may have different widths. The third floor panel may be selected such that a sum of the widths of the first, second, and third floor panels corresponds to the total width of the building unit in accordance with the floor plan.

An isolation block is useful for sealing a flute of a fluted metal deck and a movement joint between the metal deck and an adjacent wall configuration. The isolation block includes a flute sealing portion adapted to snugly fit into one of the flutes of the fluted metal deck, a joint sealing portion for sealing a movement joint, and a corrugation sealing portion for sealing a corrugation between adjacent fluted deck elements or in one of the fluted deck elements.

The invention(s) disclosed herein include(s) various panels, components of panels, partitions, systems, and/or methods that increase acoustic insulation. For example, some embodiments include a movable partition where the interface between two panels includes various gaskets, damping elements, and/or perforations that mitigate sound transmission from one side of the partition to the other. In one or more embodiments, the partition and/or panel(s) include one or more upper and/or lower drops seals having a gasket that significantly impedes sound from entering a window associated with the panel(s), which in some embodiments leads to a cavity/region relative to which the drop seal is retractable/extendable.

A joint-sealing tape for sealing a joint between a first building part and a second building part contains an elongated connecting element and at least two sealing elements which have a predetermined geometry and are positioned on the connecting element, spaced apart, side-by-side and running in the longitudinal direction of the connecting element.

An object is to provide a soundproofing structure which exhibits high soundproofing performance in a broad frequency band, can be miniaturized, can ensure ventilation properties, and has a light transmittance, and a cylindrical structure, a window member, and a partition member including this soundproofing structure. Provided is a soundproofing structure including: a soundproofing cell which includes a frame having a frame hole portion passing therethrough and a film that covers the frame hole portion and is fixed to the frame, in which the film has a plurality of through-holes passing therethrough in a thickness direction, an average opening diameter of the through-holes is in a range of 0.1 m to 250 m, and a vertical direction of a film surface is disposed so as to be inclined with respect to a direction of a sound source to be soundproofed.

A bin is described for use on a robotic picking system grid. The bin is capable of removing liquids from beneath a robotic picking system following spillages or sprinkler deployments.

The invention relates to a drywall construction system comprising a plurality of metal profiles which at least on one side are panelled using dry construction boards. At least on this one side spring rails are arranged between the metal profiles and the dry construction boards. The invention is suitable, in particular, for improving sound insulation in lightweight steel constructions.

A modular, reusable temporary enclosure system is particularly suited for the renovation of buildings having stacked concrete floors supported by steel and/or concrete columns. The system consists of a set of track components, one fastened to the floor, and one fastened to the ceiling. Columns assembled from rigid panels are supported and aligned between these components. The panel edges are connected to one another by an interfacing spline assembly. To ensure that the components can be brought up to the construction site by elevator, individual panels are shorter than the full distance between the floors.
