A device for assisting to secure a bridge support bracket to a beam, the device comprising: a support frame, a hook to secure the support frame to the beam, a clamp to grasp and hold the bracket, and a pivot axle to pivotally connect the clamp to the support frame. When attaching at least two spaced apart such devices to the beam, then clamping a support bracket in each of the at least two spaced apart devices, both support brackets can be pivoted to a position where wood boards attached to the top of the support brackets are held in a not horizontal position. By then placing a wood stud in a position where it spans the two support brackets and attaching the wood stud to the respective bracket wood boards, a workman can then further pivot the support brackets to where the wood boards extend horizontally away from the beam.

The present invention makes it possible for sounding of an inspection location on an outer wall of a building or the like to be performed using a simple operation. A user interface device accepts an input for designating an inspection location. The mobile robot device flies autonomously and moves to the inspection location, on the basis of the input into the user interface device and the current location of the mobile robot device. The mobile robot device inspects the inspection location using an inspection means such as a sounding means.

A bridge detecting vehicle with two foldable arms, including: a vehicle body, slewing mechanisms, horizontal and vertical arms and telescopic arms. One end of the two horizontal arms is respectively arranged on the slewing mechanisms, and the other end of the two horizontal arms is respectively connected to the two horizontal arms. A crossed arm is provided between the two horizontal arms. The two vertical arms are respectively connected to the two horizontal arms via ball joints. A detecting device is respectively provided at rear ends of the two telescopic arms.

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.

An imaging support device (10) includes an imaging point specification unit (22) that specifies an imaging point of a structure on the basis of drawing information, an imaging planning unit (24) that generates imaging plan information including at least one of imaging position information or imaging range information of an imaging device at each imaging of the structure on the basis of the specified imaging point and image quality information, an actual imaging information-acquisition unit (28) that acquires actual imaging information including at least one of actual imaging position information or actual imaging range information of the imaging device at each imaging of the structure, and an imaging support information-generation unit (30) that combines the imaging plan information and the actual imaging information with the drawing information and allows a display unit (13) to display combined information.

The present invention provides a structure member specification device and a structure member specification method capable of easily and accurately acquiring member identification information indicating a member included in an image of a structure captured by an imaging device when the structure is inspected. The structure member specification device acquires first space information on the structure in a local coordinate system image captured by an imaging device, and transforms the acquired first space information into second space information in a global coordinate system; prepares a member table in which third space information on each member that constitutes the structure in the global coordinate system and member identification information indicating each member are registered in an associated manner; specifies, on the basis of the transformed second space information and the third space information registered in the member table, the third space information corresponding to the second space information; and acquires member identification information corresponding to the specified third space information.

Disclosed are an imaging plan generation device, an imaging plan generation method, and a program that generate an imaging plan for efficiently imaging captured images for use in inspection of a bridge without omission. An imaging plan generation device (400) includes a space information acquisition unit (401) that acquires space information of a panel, a first decision unit (403) that decides a plurality of deck slab imaging positions and postures of a camera based on the space information of the panel, a second decision unit (405) that decides, based on the space information of the panel, a plurality of steel member imaging positions and postures of the camera in imaging a plurality of joint portions of steel members with the camera, and an imaging plan generation unit (407) that generates an imaging plan of a camera-equipped mobile robot based on the plurality of deck slab imaging positions and postures decided by the first decision unit and the plurality of steel member imaging positions and postures decided by the second decision unit.

A platform disposed below at least one bridge main cable and method of erection thereof. The platform comprises a plurality of elongate decking support beams extending cross-wise of and disposed below the main cable and decking applied thereto. In accordance with one embodiment, a plurality of slings are spaced longitudinally of the main cable, and each extends around the main cable and is attached at its ends to a respective one of the support beams. A guy is attached to at least one of the slings for restraining the sling from slippage along the length of the main cable. In accordance with another embodiment, a plurality of main cable clamps are grippingly attached to the main cable and are spaced longitudinally of the main cable. At least one pair of elongate members sre each attached at one end to a respective one of the main cable clamps and at an other end to the respective support beam.

An erected platform which contains parallel lines of trusses connected end-to-end and method of erecting thereof, as illustrated in FIGS. 20 to 23. Each truss has two sides for chords respectively, with apertures or eyelets at the ends. First and second other trusses for a pair of parallel lines respectively are connected by positioning a first other truss adjacent the decking laid on an existing platform portion. Apertures on first respective sides of the first other truss and one of the existing trusses are connected by a first pin and the first other truss swung into an end-to-end position with the one existing truss and a second pin inserted in apertures on second respective sides of the first other truss and the one existing truss. The first pin is removed and the first other truss swung out of the way so that the second other truss may be attached. The second other truss is positioned adjacent the existing decking and similarly connected end-to-end with the other existing truss. The first other truss is then swung back into position for end-to-end attachment to the one existing truss and the second pin re-inserted.

A foldable quad-chord truss which can be connected end-to-end with like trusses. The chords of each pair of chords are rigidly attached, and connector members intermediate the ends are each swivelly attached to each of the chords of each chord pair to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to beams or connector members thereof which beams may extend between a parallel pair of the trusses.
