Abstract:
A surface underlayment system and its method of manufacture that is sandwiched between an impact-receiving upper surface and a lower foundation. The energy absorbing system has subassemblies of interconnected modules that cooperate to absorb and distribute impact forces applied thereto. Each module has one or more frustoconical support structures. At least some of the frustoconical support structures have bases that underlie the upper impact-receiving surface such as a golf putting green, a football field, marine decking, and senior living flooring.
Abstract:
The present set of inventions relates to the field of building and in particular to building constructions and to processes for manufacturing building constructions comprising tensioned and non-tensioned tendons and can be used to construct residential, public and office buildings and constructions as well as for reconditioning or restoring the same.The technical result consists of the provision of relatively long-extended constructions or complicated shape constructions working as a single pre-tensioned construction and characterized by high carrying capacity, stability and rigidity.Said technical result is obtained by the fact that in a multi-component building member comprising at least two components and pre-tensioned tendons, each component is made as a tendons module comprising an initial and a final supporting elements with holes for the pre-tensioned tendons and with a stand for placing anchors and tensioning arrangements; and a reinforcing cage located between said supporting elements and comprising an upper and a lower elements in the form of a grid with a cellular structure, the cells having the shape of an equilateral polyhedron, and at least one median element under the form of a space reinforcement structure comprising inclined reinforcement bars forming equilateral polyhedral pyramids oppositely oriented in space, the pre-tensioned tendons of the first component being anchored at the initial and final supporting elements of the same, the pre-tensioned tendons of each following component being anchored at the final elements of the previous and the current components.Said technical result is obtained as well by the fact that in a process for assembling the multi-component building member, the median, the upper and the lower components of the tendons module are preassembled, attached between the initial and the final supporting elements, the tendons are inserted and then pre-tensioned, wherein, starting with the second tendons module of the construction, the anchor of the pre-tensioned tendons is mounted on the final supporting element of the previous tendons module, whereas a tensioning arrangement is mounted on the final supporting element of the pre-tensioned tendons module.
Abstract:
A modular plastic floor tile is formed by molding a body of a first polymer compound and overmolding features onto the body from a second polymer compound. The compounds may be different from each other in hardness and/or color. The overmolded features may include skins on the sides and bottoms of support member cores disposed below the tile lower surface.
Abstract:
A timber access mat having an electrical grounding feature includes an electrically conductive cover layer that is removably carried over the top of the body of the timber access mat. The electrically conductive cover layer can be formed from one or more sheets of expanded metal such as expanded steel. The layer is joined to a perimeter frame that includes offset connector tabs that allow mats to be positioned side-by-side. The connector tabs are paired with cable guides to protect the cable leads that connect the mats. The perimeter frame and conductive cover layer can be added to traditional timber access mats when electrical grounding is required and then removed and stored when not required.
Abstract:
A rig mat frame has at least two longitudinal frame members and at least two lateral frame members defining a deck insert opening therebetween. Each longitudinal frame member has a C-shaped channel facing the deck insert opening and extending along the length of the longitudinal frame member. At least one C-shaped channel has a longitudinally extending flange with a channel opening providing access into the C-shaped channel. A flange panel is removably fastened to the frame and closes the channel opening when the flange panel is fastened to the frame. A plurality of deck inserts are disposed within the frame and extend across the deck insert opening with the ends of each deck insert disposed in the C-shaped channels. And each of the plurality of deck inserts is removable from the C-shaped channels when the deck insert is positioned in alignment with the channel opening and the flange panel is disconnected from the frame.
Abstract:
A plastic floor tile is formed by molding a body of a first polymer compound and overmolding features onto the body from a second polymer compound. The compounds may be different from each other in hardness and/or color. The overmolded features may include raised pads on the upper surface of the tile. The pads on the upper surface may be injection-molded from the lower surface through through-holes, which are smaller in area than the area of the pads.
Abstract:
Modular floor tiles and modular floors are described herein. A modular floor tile may include a top surface layer, a plurality of edge surfaces, an interlocking mechanism for attachment to adjacent tiles, and a support system. The support system may additionally include a first rigid level and at least one resilient support member disposed under the top surface layer, the at least one resilient support member extending to a distance further from the top surface layer than the first rigid level. The at least one resilient support member may be compressible toward the top surface layer. A modular floor may include a plurality of interlocking tiles connected to one another. A method of forming a modular floor that includes an interlocking modular tile is also disclosed.
Abstract:
A connection surface that is disposed on at least a portion of a face of a structural unit comprises a first convex surface and a first concave surface arranged substantially along a first line. The shape of the first concave surface is complementary to the shape of the first convex surface. A second convex surface and a second concave surface are arranged substantially along a second line that is substantially parallel to the first line. The shape of the second concave surface is complementary to the shape of the second convex surface. The concave-convex order of the second line is reversed relative to the first line, such that the second convex surface corresponds with the first concave surface and the second concave surface corresponds with the first convex surface.
Abstract:
An interlocking building block, and procedure for constructing the same, having a planar locking mechanism and a spatial locking mechanism. The planar locking mechanism being a three-clawed piece built around an equilateral triangle with protruding arms and grooves corresponding to a circular arc. The protruding claws are rotated on a plane around a center of rotation. These align with grooves of another three-clawed piece to offer a locking mechanism, where the center point of the circular arc is identical to the center of planar rotation. The spatial locking mechanism may have a hexagonal prism placed next to the three-clawed piece and connected to the corners of the equilateral triangle, into which the three-clawed piece is placed so that the protruding claws extend beyond the hexagonal prism, or the spatial locking mechanism consists of protrusions ensuring a groove/taper connection and connecting grooves, so that each piece contains protrusions and grooves.
