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.

The invention relates to a roadway track (10) for a vehicle (T), said roadway track having a roadway face and being suitable for being rolled up and designed to be placed on a ground and presenting a rolled-up position and a deployed position in which said roadway track extends substantially parallel to the ground.

The roadway track comprises at least a first track portion (14) and a second track portion (16), the first and second track portions being connected to each other by a pivot connection (18) having a pivot axis (A) that extends in a direction that is substantially perpendicular to the roadway face, whereby the first track portion can pivot relative to the second track portion about the pivot axis so as to form a bend (V).

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.

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.

A mat of revetment blocks formed with interior revetment blocks having interlocking arms and sockets. The mat has opposing sides formed with revetment toe blocks having either an arm or socket that interlocks with a socket or arm of the interior revetment blocks. The toe blocks each have an outer linear edge that forms a linear border of the mat. The toe blocks rest on respective anchor portions that extend into the ground. The mat can be used to form a roadway.

A rig mat system includes a plurality of rig mats each comprising a rectangular frame and one or more billets supported by the rectangular frame, a link configured to releasably couple the plurality of rig mats together, the link including a link frame comprising a base plate having a plurality of laterally extending arms, and a plurality of connector assemblies releasably connectable to the plurality of arms of the link frame, wherein each connector assembly comprises an externally threaded fastener, an internally threaded nut configured to threadably connect to the externally threaded fastener, and a washer positionable about the fastener and having an elongate central aperture.

A paving slab. The paving slab has a unitary body made of concrete-based material, the body having sidewalls extending between top and bottom faces, providing the body with a thickness. The top face is provided with longitudinal false joints defining rows extending from a first to a second side of the unitary body. The first side has a staggered outline and the second side has a stepped outline, the first and second sides being able to engage with respective first and second sides of an adjacent slab shaped as the paving slab, but rotated by 180 degrees. When several of the slabs are assembled on a surface, it creates an illusion that the surface is covered by individual plank pavers randomly assembled.

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.

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.

A paving machine for reducing transition marks in a mat. The paving machine may comprise a frame, a tow arm, a screed assembly, a sensor and a controller. The screed assembly includes a main screed plate and an extension plate. The main screed plate is configured to pave a first surface section of the mat. The extension plate includes an extension trailing edge having an inner end. The extension plate is configured to pave a second surface section of the mat. The sensor is configured to sense transition marks in the mat proximal to an intersection between the first and second surface sections and to transmit data indicative of such to the controller. The controller may be configured to determine from the data received from the sensor when the inner end is disposed above or below the first plane, and move the inner end to the first plane.
