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.

The present invention relates to a variably dimensionable bridge (10) comprising pre-engineered components provided in a kit. The pre-engineered components are constructed of fibre reinforced polymer (FRP) composite material and include at least one floor module (14) for providing a floor; at least two girders (12) for providing opposing substantial vertical sides; and at least two cross beams (16) to lend support to the girders (12). Also described, is a method for constructing a bridge (10) of variable dimensions comprising the use of pre-engineered components provided in a flat-pack kit.

A composite I-truss is provided, that comprises a pair of top and bottom flanges and an extending intermediate web having a first end secured to the first flange and a second end secured to the second flange. Each flange comprises one or more longitudinal beams secured to the flange connectors. The web comprises at least a pair of flange connectors extending away from the flange and toward the web. The web comprises a plurality of linking struts located at a plurality of longitudinal positions along a length of the I-truss and connecting the flange connectors of the first flange to the flange connectors of the second flange.

An apparatus comprising a gangway having a proximal end and a distal end. A cage assembly is connected to the distal end of the gangway. The apparatus further comprises a container spotting system including a camera mounted such that its field of view will show a hatch cover of a container when the hatch cover is in a predetermined location. Video electronics are in electrical communication with the camera. The container spotting system further includes a display device in electrical communication with the video electronics, the display device being operative to show at least a selected portion of the field of view of the camera. The camera may comprise an outdoor dome camera mounted to an underside of the gangway.

A walkway structure includes a first frame spaced apart from the ground in a vertical direction and extending in a first horizontal direction, a footboard located on a side surface of the first frame and comprising at least one first hole, at least one bracket coupled to the footboard and the first frame, and a first coupler configured to couple the bracket to the first frame, wherein the bracket includes a first plate coupled to the footboard, a second plate coupled to the first plate, and a third plate coupled to the second plate, wherein a lower surface of the third plate is in contact with an upper surface of the first frame.

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 cable detection robot and a working method thereof, wherein the cable detection robot includes: a first main body, a second main body, and a rotatable mechanism. The first main body and the second main body each include a support, a driving apparatus, and a holding apparatus; the driving apparatus includes a first wheel and a driving motor, to drive the first wheel to move along a cable through the driving motor; the holding apparatus is symmetrically arranged on two sides of the support, each side includes a first servo motor, connecting to a supporting wheel group; the supporting wheel group is perpendicular to a surface of the cable, the holding apparatus holds or is separated from the cable through rotation of the first servo motor, and relative positions of the first main body and the second main body are adjusted through the rotatable mechanism to implement obstacle surmounting.

The invention includes a work platform and support system that includes a hub and joist configuration, wherein the hubs and joists are capable of articulation, or pivoting. One method of installation allows for sections of new work platform system to be extended from an existing suspended work platform system. The system is also capable of supporting, without failure, its own weight and at least four times the maximum intended load applied to it.

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.
