A portable fencing track that is readily assembled and disassembled at different venues includes a series of modular panels disposed adjacent to one another and interconnected to form an elongated central fencing floor. A piste or strip of electrically conductive material is placed and positioned with respect to the elongated central floor, and a perimeter floor is arranged so as to surround the central floor and the piste or strip. A threshold, preferably adjoining each of the modular panels located adjacent to the perimeter flooring, has lateral and end sections overlying adjacent portions of the strip and the perimeter floor, and at least one of the threshold sections defines a channel to receive wiring. Support elements are mounted to each of the floor panels and the perimeter floor to resiliency support the floor panels and the perimeter floor on a base surface and minimize damage over time to the ankles or hips of fencers. A process of assembling the track is also discussed.

An impact-absorbing device and a structure for blocking noise between floors by using same are proposed. The impact-absorbing device has a body (100) including an upper cylinder (120), of which the inside is empty and which has an opening opened downward, and a lower container (140), of which the upper end is inserted into the upper cylinder (120), so that the length thereof can extend and contract has an elastic support (160) formed in the transverse direction inside the upper cylinder (120) and/or the lower container (140), and includes a transmitting body (180), which is supported by the elastic support (160) so as to transmit, to the elastic support (160), impact applied to the upper cylinder (120), and thus impact is absorbed since the elastic support (160) is elastically deformed by the transmitting body (180) while the length of the body (100) is reduced due to the impact.

The present invention relates to: a floor tile including a fabric material, and comprising a balancing layer, a noise prevention layer, a functional sheet layer, a fabric material layer, and a surface coating layer; and a manufacturing method thereof and more specifically to a floor tile including a fabric material and a manufacturing method thereof, the floor tile being a functional tile having a natural texture and a three-dimensional effect possessed by the fabric material, having excellent durability, preventing delamination of the fabric material layer, exhibiting excellent mechanical properties such as tensile strength, and enhancing cleaning facilitation.

A multilayer acoustic and shock absorbing cushion, consisting of a buffer layer, two waterproof moisture-permeable layers respectively mounted on the corresponding two sides of the buffer layer, and two surface layers respectively mounted on each side of the waterproof moisture-permeable layers away from or at a distance from by the buffer layer. The buffer layer, each of the waterproof moisture-permeable layers, and each of the surface layers are needle punched and bonded to form a single body. The multilayer acoustic and shock absorbing cushion of the present invention is primarily used in building partitions and wall systems to prevent noise and vibration produced when household residents are doing physical activities from disturbing other neighbors. The multilayer acoustic and shock absorbing cushion is further provided with advantages including acoustic and shock absorbing functions, anti-efflorescence ability, and good cement bonding stability.

A method of reducing sound transmission in a building constructed using horizontal cross laminated timber (CLT) panels to provide a floor of the building and a floor assembly are described. In an implementation, the method includes: attaching a plurality of energy transmission control mounts to a ceiling side of one or more of the cross-laminated timber panels using fasteners; attaching a plurality of furring channels to the energy transmission control mounts; and attaching a cross laminated timber sheet to the plurality of furring channels to form an exposed ceiling layer.

A load distributing and absorbing system that lies below a superstructure material which is exposed to percussive forces. The load distributing and absorbing system is interposed between the superstructure material and a foundation. The system has a barrier layer that lies below the superstructure material and an underlayment infrastructure positioned below the barrier layer. Included in the underlayment infrastructure are hat-shaped absorbing members.

The present invention provides an impact absorbing flooring that reduces an impact caused by falling of a user. The impact absorbing flooring includes a structural layer having a plurality of impact absorbing structures, each of which is a truncated pyramid-shaped structure and has a recess on a side of the truncated pyramid that is substantially not horizontal to a ground surface.

A floor assembly for a performance space is disclosed. The assembly has a planar resilient floor board supported above a base board on a primary support system comprising a plurality of resilient (preferably elastomeric) supports. A secondary support system comprises a plurality of fixed support members and a plurality of movable support members. Each movable support member is movable in a direction parallel to the plane of the floor board between a first position spaced from a corresponding fixed support member such that the floor board is unsupported by the support members and a second position in contact with the corresponding fixed support member such that the floor board is supported by the support members. In the first position, the floor board is in a sprung configuration and in the second position, the floor board is in an unsprung configuration. The invention therefore provides a performance floor which is switchable between sprung and unsprung configurations.

A vibration absorption device for acoustic insulation for a building structure comprises an absorbent cushion and a vibration isolation cushion. The building structure is selected from a ceiling structure, a floor structure and a partitioning structure separating two adjacent building compartments or a building compartment and the external environment. The absorbent cushion comprises sound absorbing material and the vibration isolation cushion comprising vibration isolation material. The vibration isolation cushion overlies and is laminated to the absorbent cushion. The vibration isolation cushion is rigid relative to the absorbent cushion. The absorbent cushion is supple relative to the vibration isolation cushion. The vibration absorption device is mountable to the building structure, to isolate vibrations and to provide acoustic insulation between the two separated and adjacent building compartments.
