A grating system provides enhanced see through characteristics and typically includes longitudinal deep bars, axial crossbars, axial filler bars between the crossbars and longitudinal joining bars which join the crossbars and filler bars to one another. The deep bars are part of a first subassembly and the other bars are part of a second subassembly which may be lowered to join the two subassemblies to one another. The crossbars and filler bars are typically seated on the deep bars. The joining bars are typically above and aligned with the deep bars. The upper surfaces of the crossbars and filler bars are usually substantially flush with one another. The grating system is configured to support vehicular and pedestrian traffic. |

A connector apparatus includes first and second spaced apart generally coplanar walls and a support between the first and second walls. The first wall includes a first guiding surface and a first stopping surface extending at a first angle to the first guiding surface. The second wall includes a second guiding surface opposite at least a portion of the first guiding surface and generally facing towards the first guiding surface, a second stopping surface extending from the second guiding surface and away from the first guiding surface, and a third stopping surface extending at a second angle to the second stopping surface. The support has a fourth stopping surface, and the fourth stopping surface is disposed at third and fourth angles to the first and third stopping surfaces respectively. |

Disclosed is a grating, and more particularly a grating capable of easily and firmly fixing a second partition member to a frame member and a first partition member. This grating includes fixing projections formed at regular intervals along a longitudinal direction of the first partition members on both sides of the first partition member and on inner sides of the frame member that face a side of the first partition member; and second partition members installed between the first partition members and between the first partition member and the frame member respectively, the second partition members having insertion slots into which the fixing projections are inserted, the insertion slots being bent to subsequently contact with the first partition members facing each other or the first partition member and the frame member facing each other so that the fixing projections are inserted into the insertion slots. |

The invention relates to a road finisher with a chassis having a front bucket for receiving packing material and a conveying device for conveying the packing material from the bucket to a rear spreader screw arrangement which is arranged transversely with respect to the longitudinal axis of the road finisher and in front of a consolidation plank which is extendable, the consolidation plank, which is connected to the chassis via pulling arms and floats on the packing material, being divided centrally in the direction of the longitudinal axis into two plank halves, the consolidation plank being provided with a device for adjusting the inclination of two halves with respect to each other and having outer side cheeks. In order to counteract twisting of the consolidation plank and opening of the gap between the two plank halves, a clamping device, the clamping force of which can be set by a cylinder articulated on the chassis, is arranged between the chassis and the lower region of the outer side cheek. |

A grid plate of plastic material, with a rough, slippage-impairing top side and a rib-reinforced bottom side. The individual grid plates are kept together by a lockable, but again disconnectable, plug-in connection. The grid plates serve as fastening elements for parking places, road embankments, road ramps, and the like. |

An airport runway has a grid structure for supporting aircraft during take-off and landing. The grid structure extends over a liquid reservoir and comprises bars defining therebetween spacings extending downwardly through the grid structure and in open communication with the reservoir, which has means, e.g. expansible chambers, for raising the level of liquid in the reservoir through and above the grid structure to remove snow and ice from the latter. Barriers around, and above the level of, the grid structure confine the liquid.

A pair of rectangular dished plates are ring-hinged together at their adjacent edges and each provided with spaced upper cross battens, the second plate also having cross battens thereunder and being similarly hinged to a ground tread having spaced upper and lower cross bars; the first plate is placed in the ground and against the tire of a mired automobile wheel, and when the wheel is driven, it grips the battens to drag the plates thereunder until the plates and ground tread anchor at the ground opening formed by the rotating wheel, and so permit the wheel to ride in and up the track so formed.

A grating construction in which the grating members include upper portions defining vertical slots and lower portions defining angular slots, the spacing being such that any particle having a width and length less than the spacing of the upper portions will pass through the lower portions; however, the angular relation between the upper and lower portions prevents passage of an elongated member therethrough.

This invention provides a novel floor system which has outstanding advantages in structures, such as powerhouses, nuclear power plants, chemical plants and other such large structures whereby an adequate floor is provided with a sizeable reduction in deadweight. The deadweight design of these structures exceeds the liveweight capacity designs due to the fact that a minimum number of personnel are involved in the operation os such plants. A grating is provided whereby the weight can be reduced materially and/or the span materially lengthened so that the resulting floor support and columns is also reduced. In addition to the reduction in the weight of members, the number of support members for the new floor design is reduced materially, thereby saving additional weight and cost.
