The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

The present invention relates to the creation of thermally insulating materials derived from cellulosic materials by selectively depolymerizing the materials anatomy. Cellulosic materials may be comprised of three main biopolymers: lignin, hemicellulose, and cellulose. The present invention relates to the chemical and physical removal of lignin and hemicellulose, while leaving the cellulose unaltered to induce increased porosity within the material and the material's macrostructure matrix for use as thermal and acoustic insulation. The increased porosity will be due to the creation of closed cell voids within the cellulosic matrix. These voids will increase the thermal and acoustic insulating performance of the cellulosic materials. The selective removal of secondary biopolymers from cellulosic materials allow for isolation of other value added products that can be regenerated through fewer reactions/steps. This is a novel advantage over other similar processes that dissolve cellulose completely, making it harder to extract and isolate secondary off-stream products.

A multi-layer fire-resistance treatment (FRT) panel for use as structural sheathing. The wood structural panel may be OSB or plywood, coated or treated during the manufacturing process with a product that provides fire resistance. The treatment may be integrated with the material forming the wood structural panel, or may be a coating layer applied to the mat or mat layer. A burn-through layer also may be applied. A protective layer comprising a resin-impregnated paper overlay may be applied on one or both sides of the panel.

A second insertion plate extends from the inner surface of the face plate at the bottom edge of the face plate. A concealment portion extends from the inner surface of the face plate along the first and second side edges of the face plate. The concealment portion may include an upper section positioned above the first insertion plate and spaced from the first insertion plate by a first gap and a lower section of positioned below the second insertion plate and spaced from the second insertion plate by a second gap.

This disclosure refers to a formwork system which comprises: two or more insulating panels for receiving a fluid concrete structuring material between said panels; at least two sections to fit each other in a said panel; one or more connecting devices which comprise two extremities each for connection to a section to join two panels; wherein each panel has four ends including an upper end and a lower end opposite the upper end; wherein the panels comprise a cavity to fit one or more sections along the length of the upper end of each panel; wherein the panels comprise a cavity to fit sections along the length of the lower end of each panel; wherein the sections comprise a lateral flashing with a plurality of holes; wherein the connecting devices comprise a plurality of hooks, at their extremities, to enter in said holes of the section.

A composite building system comprising a structural frame and walls which is made of pultrusion fiber reinforced polymer (PFRP) material. PFRP provides increased performance, strength, protection, and longevity for mobile and fixed building structures, enclosures or vehicles, commonly found in residential, commercial, industrial, healthcare, aerospace, government defense, energy, and agriculture sectors. The PFRP material comprises fibers embedded in a resin matrix. Exemplary fibers are glass, carbon, and synthetic fibers. PFRP products can be formed using a pultrusion method that eliminates outgassing. An intumescent fire barrier can be applied to the PFRP to meet National Fire Protection Association fire endurance codes and standards. The composite building system increases personal safety while reducing weight, labor costs, construction time, and total cost of ownership over the life of the structure while being resistant to ballistic, seismic, corrosion, rotting, impact, and insect damage. In addition, a wall and wall assembly consisting of the PFRP material is impervious to water and air and does not require an exterior finish coating. The PFRP wall and wall assembly can be designed to be versatile, allowing for use with both PFRP structural framing and traditional framing materials, such as concrete, steel, and wood.

A booth includes an internal space configured to be used by a user, a door which is controlled to unlock in an electric-powered manner when an information is detected based on a user operation, and a monitor screen which is used in order to project an image output from a device brought by the user.

Described herein are building panels and surface covering systems useful for spaces requiring acoustic control and design flexibility, and methods to prepare the same. Such building panels and surface covering systems comprise an building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising a body having an upper surface opposite a lower surface and side surfaces extending there-between; backing having a first side opposite a second side and comprising denim web and a low-melt polyester bicomponent fiber; wherein the first side of the denim web backing is in contact with the upper surface of the body; and wherein the denim web backing has a web basis weight from about 1150 to about 1350 g/m.sup.2. In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

An oblong cantilevered support includes a pair of latitudinally spaced apart oblong resilient members connected by a pair of longitudinally spaced apart blocks. The longitudinal spacing between the blocks can be adjusted. One or both of the members can have a tapered profile causing the stiffness of the member to vary along its length. Adjusting the spacing between the blocks and/or sliding a variable stiffness member longitudinally with respect to the blocks can adjust the stiffness of the overall support. Each member can be made from a unitary piece of fiber composite material such as a carbon fiber infused polymer wherein the orientations of the fibers are varied to provide both bending and torsional strength and stiffness that varies along the length of the member. The tapered geometry can be formed by a pair of parallely spaced apart oblique trapezoidal truncated pyramids interconnected by a webbing strip.

A protective enclosure for equipment located outside, such as, for example pipeline and wellhead valves, dewatering pumps, etc. includes a wall frame assembly constructed of a plurality of vertical frame members that are connected together at their tops and bottoms by a plurality of angle-iron members. Wall assemblies comprising insulated wall panels that are connected in a side-by-side relation by tongue-and-grove couplings are attached to the wall frame with the bottoms thereof supported on angle-iron members that connect the bottoms of the vertical frame members. A roof assembly can be attached to the wall frame in a stationary fashion or in a movable fashion to allow the roof to open, permitting access into the enclosure for servicing equipment housed therein. The enclosure has other features as described in the specification in further detail.
