A device (2) for thermally insulating a building wall (1) from the outside, being applicable in particular to walls and roofs, includes, starting from the wall, a layer (3) of impermeable rigid insulation, spacers (4) and a perforated rigid facing sheet (6) at a distance from the layer (3) of rigid insulation so as to form an air gap (7) between the facing sheet and the layer (3) of rigid insulation. A layer (8) of granular insulation (9) in divided form is contained in synthetic textile bags (10) placed in the air gap (7). A method for implementing such a device is also described.
摘要:
An acoustic structure that includes a honeycomb having cells in which septum caps are located. The septum caps are formed from sheets of flexible material that may be perforated before or after the material is inserted into the honeycomb. The flexible material is sufficiently flexible to allow folding into the shape of a septum cap. The flexible material is also sufficiently stiff to provide frictional engagement and locking of the septum cap to the honeycomb cell when the cap is inserted into the honeycomb during fabrication of the acoustic structure. An adhesive is applied to the septum caps after the caps have been inserted into the honeycomb cells to provide a permanent bond.

The present disclosure describes use of filamentous algae to form insulating construction materials which provide thermal and noise insulation. Algae from the order Zygnematales, the Cladophorales, or the Ulotrichales can be dried and formed for use as insulating material. Algae mass can be combined into several layers, using a binder to attach the layers to each other. A composite material of algae mass and an additive can be used and form the body of insulation panels having honeycomb-shaped chambers, which are sealed by a foil that is laminated onto the body.Various plants for cultivating algae for use in construction material are disclosed. Plants utilizing gravity harvest comprise cultivation ponds located at a slope, wherein the ponds can be opened to allow algae and water to flow downhill through a collector grill. Plants utilizing net harvest, overflow harvest or rake harvest are described. Carbon dioxide injection concepts utilizing direct and indirect injection of carbon dioxide into algae cultivation ponds are disclosed. An algae harvesting machine is disclosed. Control concepts for controlling the growth of algae in an algae cultivation plant are described.

A waterproof heat-insulation construction method aims to spread a layer of waterproof heat-insulation powder through a waterproof heat-insulation module on a work surface to form waterproof and heat insulation effect thereof. The method comprises the steps of: first, anchoring at least one waterproof heat-insulation module which can be arranged on the work surface; then holding the waterproof heat-insulation powder in the waterproof heat-insulation module in contact with the work surface to form a waterproof heat-insulation layer. The invention also provides a corresponding waterproof heat-insulation module which can be constructed in a modular fashion to achieve waterproof and heat insulation effect for buildings.

An acoustic structure that includes a honeycomb having cells in which septum caps are located. The septum caps are formed from sheets of acoustic material and include a resonator portion and a flange portion. The flange portion has an anchoring surface that provides frictional engagement of the septum caps to the honeycomb cells when the caps are inserted into the honeycomb during fabrication of the acoustic structure. An adhesive is applied to the anchoring surface of the septum caps after the caps have been inserted into the honeycomb cells to provide a permanent bond.

A honeycomb acoustic unit is provided, the unit comprising first and second honeycomb layers, the layers being made of honeycomb core, each being formed by metallurgical bonds, and a deformable septum having two opposing sides, the first and second honeycomb layers being metallurgically bonded to the two opposing sides of the deformable septum.
摘要:
A sound-eliminating board including sequentially bonded sound transmissible top layer, rigid sound-eliminating middle layer, and elastic sound-eliminating bottom layer. The sound transmissible top layer allows sound waves to penetrate through it into the rigid sound-eliminating middle layer, which includes a plurality of checkered partitions to define a plurality of open-topped small compartments. Sound waves penetrated into the rigid sound-eliminating middle layer reflect repeatedly in the small compartments to result in energy dispersion and counterbalanced energy due to overlapped amplitude of reflected sound waves, and are finally eliminated. In case of any residual low-frequency sound waves that penetrate through the rigid sound-eliminating middle layer into the elastic sound-eliminating bottom layer, they are further eliminated in the bottom layer.
摘要:
An acoustically significant composite panel having a general sound-absorbing face (or a general sound-diffusing face) and a tuned sound-absorbing face. Such a panel includes a sandwich or composite of a first layer of molding media, a honeycomb of cells and a second layer of molding media. The first layer has at least one or more apertures in it that convert the corresponding cells into Helmholtz resonators. These Helmholtz resonators can be tuned to the same or different frequencies. The second layer is generally sound-absorbing. A general diffuser structure can be attached to the second layer. These panels can be attached to the walls and/or ceilings of a room to control its sonic quality. Also, these panels can be suspended vertically below a ceiling to control noise.
