A segmental joint of cast-in-place UHPC bridge beam. The joint comprises a female joints at an end of a first segment and male joints at an end of a second segment, wherein each female joints and the male joints are correspondingly connected to form a tongue-and-groove connection, and each of the male joints is of a structure with big outer part and small inner part. The beam segment joint of the present disclosure improves the structural strength of the bridge and facilitates on-site construction, which not only applies to the joint connection between the segmental cast-in-place UHPC beam segments and the construction of the segmental cast-in-place UHPC beam segment, but also to joint connection of UHPC bridge deck of UHPC-steel composite beam and of full UHPC bridge deck of UHPC composite box girder with corrugated steel webs and to UHPC bridge deck construction.

A bridge overhang bracket assembly includes a top member having an upper surface. The top member and a diagonal member are pivotally attached proximate to respective distal and upper ends thereof. The diagonal member and a side member are pivotally attached proximate to respective lower and bottom ends thereof. A connection element is mounted to the top member and is pivotally attached to a top end of the side member. The connection element is translatable along the top member to adjust a longitudinal position of the connection element relative to the top member. The connection element does not extend above the upper surface of the top member.

A chipping robot has a chipping gun attached to the end of a multi-axis robotic manipulator mounted on a powered, movable, platform that can be raised and lowered to access the underside of structures that may be substantial distances above the ground, for example, the underside of an elevated highway. The entire assembly is maneuverable under the work area and the platform may raised to access the concrete. Once the work area is in reach of the arm, the device is able to use numerous tools to complete essential steps of chipping portions of the concrete.

A method for displacing a ceiling formwork for a nearest concreting section, wherein first and second supporting devices for supporting the ceiling formwork are arranged below the nearest concreting section. Said supporting devices each have a shuttering position and a stripping position, wherein the ceiling formwork is raised to a concreting level in the shuttering position and lowered relative to the concreting level in the stripping position. The first supporting device is moved into the stripping position and the second supporting device is moved into the shuttering position, and a collision protection element is arranged between the second supporting device and an end face of the ceiling formwork when the end face of the ceiling formwork strikes the second supporting device after passing over the first supporting device, so the collision protection element forms a flank rising in the displacement direction for guiding the ceiling formwork in the displacement direction.

A lowering system for lowering ceiling formworks during the removal of formworks of a building ceiling, comprising a reciprocating piston and a support base, and a locking device, wherein the reciprocating piston is slidably mounted in the support base, and can be pushed from an extended working position to a lowered position, and can be locked in the extended position by means of the locking device. The locking device has a pivot bearing and an eccentric lever, wherein the eccentric lever is rotatably mounted in the pivot bearing, and the reciprocating piston and the support base are supported against each other in the working position by means of the eccentric lever.

The present disclosure relates to a segmental joint of cast-in-place UHPC bridge beam, and belongs to the field of bridge structure. The joint comprises a plurality of female joints disposed at an end of a first segment and a plurality of male joints disposed at an end of a second segment, wherein each female joints and the male joints are correspondingly connected to form a tongue-and-groove connection, and each of the male joints is of a structure with big outer part and small inner part. The beam segment joint of the present disclosure not only applies to the joint connection between the segmental cast-in-place UHPC beam segments and the construction of the segmental cast-in-place UHPC beam segment, but also to joint connection of UHPC bridge deck of UHPC-steel composite beam and of full UHPC bridge deck of UHPC composite box girder with corrugated steel webs and to UHPC bridge deck construction.

A supporting device for the construction industry. Said device has a fixing element which rests against a side wall and is fixed at a fixing point of the side wall. Said device also has a cantilever which is connected to the fixing element and, when the fixing element is in the fixed state, projects from the side wall such that a load element can rest against a bearing point of a bearing element of the cantilever. The load element can now be displaced in a displacement direction substantially parallel to the side wall relative to the cantilever and, when the load element rests against the bearing element of the cantilever, the cantilever is coupled to the load element such that a displacement force component acts on the cantilever in the displacement direction when the load element is displaced, said displacement force component resulting in a torque on the cantilever.

An automated concrete bridge paver with an ability to provide effective control of a concrete paver by a remotely locatable concrete bridge paver operator 202, which includes a fixed operator control station and a mobile wireless remote operator control station 210 which can be used when the remotely locatable concrete bridge paver operator 202 leaves the operator control station 204. Mobile wireless remote operator control station 210 includes a video screen which can display live video images from a plurality of remote wireless camera and sensor pods 212, which can be fixed on the paver or moved about the paver on an articulated arm, with or without a human basket.

An apparatus for adjusting a haunch height includes a support angle, a rod or bar, a coupler, and a bolt. The support angle includes a horizontal portion and a vertical portion, and the vertical portion includes a plurality of holes spaced apart from each other. At least one end of the rod or bar is threaded. The coupler includes an internal threading. The bolt is configured to extend through one of the plurality of holes in the support angle and into a portion of the coupler.

An apparatus for adjusting a haunch height and related systems and methods are described. The apparatus may include a support angle. The support angle may include first and second flanges, a surface of the first flange including a hole. The apparatus also may include a coil rod and a rotatable nut.
