A cable-stayed suspension bridge structure suitable for super long spans by comprising a horizontally arranged main bridge main beam, wherein vertical main towers are arranged at ends of the main bridge main beam, and each main tower is anchored by stay cables; a main bridge vertical support and a longitudinal elastic damping stopper are arranged at positions of the main bridge main beam close to the main tower, and the main beam is kept stable longitudinally by virtue of the geometric stiffness of the cable force of the stay cable and the longitudinal elastic damping stopper.

A mobile bridge module includes a reinforcement applied in a non-destructive manner. This might alternatively and/or additionally be defined as a non-destructively reinforced mobile bridge module.

A truss frame for a bridge and/or support includes two elongated, parallel longitudinally-extending post pipes having an outer circumference; two parallel crossbars extending perpendicularly to the post pipes; and a length-adjustable elongated diagonal element. The parts are hingedly and detachably bolted to one other. Two parallel connecting plates secured near each post pipe end extend away from one another on a common, imaginary plane containing the post pipe and crossbar longitudinal axes. Each crossbar and diagonal element has opposite ends hingedly and detachably bolted to a connecting plate. At least two rosettes are welded to each post pipe at a distance from one another corresponding to an integer multiple of a module scaffold modular size. A connecting body is welded to the connecting plate near at least two post pipe ends associated with the same crossbar and surrounds the respective post pipe outer circumference.

A bridge span assembly can include multiple bridge spans, each of which can include a frame, a stabilizing member for engaging with construction equipment, and a coupling joint for attaching the frame to construction equipment with an elongate member. By attaching the bridge span assembly to construction equipment with the stabilizing member and coupling joint, an operator can place the bridge span assembly over an obstacle using only the construction equipment. The construction equipment or other equipment can then safely traverse the obstacle without causing damage to the obstacle or the construction equipment.

A slab bridge structure having improved rigid connection strength between bridge girders and concrete piers. The slab bridge structure has a rigid connection structure in which slab concrete (3) is poured between side surfaces of bridge girders (1) arranged in line in a bridge width direction, throughout a longitudinal direction of the bridge girders, connection concrete (12) in which bridge girder portions (1) supported by a bridge seat (2a) of a concrete pier (2) that supports the bridge girders are embedded is further added onto the bridge seat, and the slab concrete and the concrete pier are concrete-joined through the connection concrete, the slab bridge structure further includes: a connecting rod (13) embedded in the concrete pier and projecting upward from the bridge seat of the pier; and a connecting plate (14) connecting upper end portions of the adjacent bridge girder portions.

A high-damping rubber isolation bearing, an intelligent bearing and a bearing monitoring system are disclosed. The high-damping rubber isolation bearing comprises a top bearing plate, a bottom bearing plate, a high-damping rubber bearing body and a base plate, wherein at least one pressure sensing unit is arranged between the top bearing plate and the base plate, or between the bottom bearing plate and the base plate. The intelligent bearing includes a data acquisition unit, a data output unit and the high-damping rubber isolation bearing. The data acquisition unit transmits the bearing pressure measured by the at least one pressure sensing unit to the data output unit. The bearing monitoring system includes a data acquisition unit, a data output unit, a monitoring center and the high-damping rubber isolation bearing.

A hollow profile (1, 15), in particular crane girder for a crane (14), wherein the hollow profile (1, 15) has a cavity (2) and an outer wall (3) bounding the cavity (2), and at least one fastening element (4) protruding from the outer wall (3) for the, preferably re-releasable, fastening of at least one add-on part (5) to the hollow profile (1, 15), wherein the outer wall (3) has at least one passage opening (6), which opens into the cavity (2), for the fastening element (4), and an intermediate space between that portion (36) of the outer wall (3) which bounds the passage opening (6) and the fastening element (4) which is guided through the passage opening (6) is sealed with a sealing compound (7).
