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.

A production method for a waterproof and wear-resistant composite floor, comprising: first manufacturing a PVC composite layer preform (3); then performing a corona treatment and a punching treatment on a soft cushion layer (2); and finally, compounding, at one time, the PVC composite layer preform (3), the soft cushion layer (2) and a waterproof substrate layer (1) into one. Said process is simple and easy to implement, shortening the production cycle, reducing the manpower and material resources required by the production process and reducing the production cost; moreover, the waterproof and wear-resistant composite floor produced has a simple structure, and also has very good waterproof and wear-resistant performance; in addition, the waterproof and wear-resistant composite floor will not swell, and will also not split into layers or deform easily.

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 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.

The present disclosure is a method and apparatus for protecting building-related elements from collision damages. The apparatus can be designed to withstand high-impact collisions such as those caused by errant operation of heavy equipment. The method and apparatus are intended to be applicable to buildings already constructed and do not have to be implemented or considered before or during building design. In one exemplary embodiment, the apparatus can protect downspouts of warehouse sprinkler systems from collision damage that could result in pipe eruption.

A floor coating, which is prepared from 55-70% by weight of an epoxy-modified polyurethane resin, 5-10% by weight of Al.sub.2O.sub.3, 10-25% by weight of SiC, 0.4-1% by weight of a leveling agent, 0.3-1% by weight of a dispersant, 5-10% by weight of a solvent and 0.2-0.8% by weight of a curing agent. A degree of polymerization of the epoxy-modified polyurethane resin is 80-100. A scratch-resistant floor and a preparation method thereof are also disclosed herein.

An anti-explosion flooring material is disclosed. The material is prepared by foaming, modification and rust prevention treatment of an iron alloy material and other auxiliary materials having components in percentage by weight: 85% of iron, 8% of manganese, 6% of silicon, and the rest amount of carbon. Because a foaming agent and rare earth are added, the static conducting performance of the flooring material is improved.

A corner protector member for establishing and finishing a transition between a first surface, a second surface and a third surface, the first, second and third surfaces forming an inside corner. One corner protector embodiment includes a read face portion oriented inwardly in relation to the inside corner, which is securable to the inside corner, and from which integrally extends an external frontal or basal face portion, the lateral edges of which are securable alone or with the addition of an integral pin or barb to the inside corner, positively locking and engaging with the interior corner surfaces so as to firmly anchor therein and thereto.

A formable trim strip for use in connection with drywall applications includes two or more layers, including a trim strip body and a backing paper. The trim strip body extends along a body axis and has a top surface and a bottom surface. The trim strip body comprises a polymer material. The backing paper includes a portion secured to the bottom surface of the trim strip body without an intervening layer of adhesive material. The trim strip body is coated onto the portion of the backing paper when a temperature of the trim strip body is within the melting point range such that the bottom surface of the trim strip body contacts the portion of the backing paper. As the trim strip body cools to a temperature below the melting point range, the portion of the backing paper bonds to the bottom surface of the trim strip body.
