An expansion joint connects structural elements of a building structure to fill a space between the structural elements themselves. The expansion joint has a plate body and a deformable body flanked or adjacent to the plate body along the longitudinal direction. The deformable body includes two superimposed and structurally independent portions connected to each other in a removable way, or configured for a removable connection with one another.

An image processing method and system, a storage medium and a moving system are provided, and the image processing method includes: obtaining a 2D depth array D.sub.p having depth information of a target object; calculating to obtain a depth vector D=[d.sub.1, d.sub.2, d.sub.3, . . . , d.sub.i, . . . , d.sub.n], in which an element d.sub.i is an average value of elements of the i.sup.th row in the 2D depth array; calculating to obtain an edge determination vector D=[d.sub.1, d.sub.2, d.sub.3, . . . , d.sub.i, . . . , d.sub.n1], in which an element d.sub.i=|d.sub.id.sub.i+1|; calculating an average value d.sub.0=(|d.sub.2d.sub.1|+|d.sub.3d.sub.2|+ . . . +|d.sub.n1d.sub.n2|)/(n2); and comparing an absolute value |d.sub.id.sub.i+1| with d.sub.0 to identify an edge of the target object, in which in a situation where |d.sub.id.sub.i+1| is greater than d.sub.0, it is determined that the elements of the i.sup.th row in the 2D depth array D.sub.p correspond to the edge of the target object.

A waterproof sheet which is for application to a site to be waterproofed in order to prevent rainwater infiltration thereinto and retard deteriorations which proceed with time, the waterproof sheet comprising: a base layer that comprises a silicone rubber composition reinforced with reinforcing fibers and that has physical properties including high strength; and a pressure-sensitive silicone adhesive layer that has been formed on one surface of the base layer and that has a low hardness and is highly tacky. The waterproof sheet provided by the present invention less breaks than conventional waterproof sheets because of the reinforcement layer, and can conform to cracks or dislocations occurring in the surfaces to which the waterproof sheet has been applied, due to the pressure-sensitive adhesive layer formed on one surface. Since the waterproof sheet includes silicones as main components and is hence excellent in terms of weatherability, heat resistance, and freeze resistance, this waterproof sheet can retain the function required of waterproof sheets, over a longer period.

A pier maintenance system and a structural maintenance system are provided. The pier maintenance system is configured to maintain elongate members of the pier (e.g. piles). The pier maintenance system includes a delivery module, configured to navigate between the elongate members; and a maintenance module, coupled to the delivery module, and configured to navigate along the elongate members, to maintain the pier.

A work platform system for implementation in relation to a structure, as well as subsystems and components thereof and methods of implementation and use relating thereto, are disclosed herein. In at least one embodiment, the work platform system includes a first pair of flexible elements and a second pair of flexible elements, where a respective first end of each of the flexible elements is coupled at least indirectly to a first support component and a respective second end of each of the flexible elements is coupled at least indirectly to a second support component. The work platform system can further include a plurality of panel structures supported upon the flexible elements, a suspension component, and a clamp structure coupled to at least one of the first pair of flexible elements and the second pair of flexible elements. The work platform system can include one or more support extension.

A SAFE (SUICIDE AND FALL ESTOP) which is intended to prevent suicide attempts or accidents that may result in death by free fall from high structures such as bridges, viaducts and buildings that allow passage through obstacles such as rivers and elevations and can be used as a high security element to prevent falling during maintenance of said structures, bridges, viaducts automatically or manually.

A device for attachment to a bridge support bracket is adapted to be connected to an end of a support bracket horizontal component and to an end of a support bracket vertical component. The device comprises a support adapted to be attached to the end of the horizontal component, a sliding tube adapted to be attached to the end of the vertical component, and a mounting tube attached to the support for mounting the sliding for sliding movement relative to the support. A slot is in the side of the mounting tube, and a nub is attached to the sliding tube and extends through the slot. The nub has a threaded opening therein, and a threaded rod extends through and engages the threaded opening, the threaded rod being mounted for rotation but not vertical movement relative to the support, for moving the vertical piece vertically relative to the support.
