A securing system includes a fastener and a tape. The fastener includes a main body portion having a first end and a second end, a curved portion extending from the first end, first and second legs extending from the second end, and a roller extending between the first and second legs. The tape may extend around the roller and may be self-adhering.

A concrete construction (100) made by 3D concrete printing that contains: two or more layers (102, 106) of cementitious material extruded one above the other, and at least one elongated steel element (104, 108) reinforcing at least one of the two or more layers. The elongated steel element (104, 108) is provided with a first crimp. Due to the crimp, a good anchorage in concrete is obtained and the anchorage force is predictable, since the standard deviation of the anchorage force is very small. The elongated steel element can be a single steel wire with a diameter D, the amplitude of the crimp ranges from 1.05×D to 5.0×D. The elongated steel element can also be a steel with steel filaments having a maximum diameter d. The amplitude of the crimp ranges from 1.05×d to 5.0×d.

A curved panel part includes: a curved panel made of metal; and a reinforcement joined to the curved panel and made of a plurality of FRP layers including continuous fibers, in which each of the plurality of FRP layers has a single fiber direction, at least one layer out of the plurality of FRP layers has a fiber direction different from that of another layer, in the plurality of FRP layers, a proportion of layers having an angular difference in the fiber direction of 30° or more is 15% or more of all of the layers, and when calculating, by defining a maximum principal curvature direction of the curved panel as a 0° direction and a direction orthogonal to the 0° direction as a 90° direction, each of a 0° direction component and a 90° direction component regarding the fiber direction of each FRP layer of the reinforcement joined to the curved panel, by using a trigonometric function, an expression (1) is satisfied.

A horseshoe having a front end and a back end includes a base plate having a first stiffness, an intermediate layer having a second stiffness, the second stiffness being less than the first stiffness, the intermediate plate being disposed adjacent the base plate, a top plate disposed adjacent the intermediate layer and a heel wedge capable of articulating relative to the base plate.

A pad for protective garments comprises an outer layer of heat and flame resistant material, and inner layer of heat and flame resistant material, and a cushioning layer disposed therebetween. The cushioning layer is produced from a non-newtonian material. A pad assembly may be formed using the pad along with a piece of flexible material attached thereto. The pad, or the pad assembly including the pad, may be used with protective garments such as firefighter turnout gear.

Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

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.

Disclosed are interlocking elongate composite bamboo industrial mats having an upper layer with two or more elongate laminated composite bamboo panels, an intermediate layer with a plurality of elongate laminated composite bamboo panels arranged in parallel and perpendicular to the laminated composite bamboo panels in the upper layer, and a bottom layer with a plurality of elongate laminated composite bamboo panels arranged in parallel to the upper layer. The three layers are secured together with fasteners consisting of a bolt, an outward-facing concave washer engaged with the bolt head, and a sleeve nut having an outward-facing washer engaged with the sleeve nut head. The interlocking elongate composite bamboo industrial mats are configured to interlock end-to-end or alternatively, side-to-side. Each of the elongate laminated composite bamboo panels comprises a plurality of kiln-dried glue-dipped elongate asymmetrically fractured bamboo strips compressed into a solid panel devoid of air spaces.
