A method for making a prefabricated, prestressed module includes arranging one or more steel beams atop a supporting formwork element in a direction transverse to the supporting formwork element and arranging one or more precast deck elements across the one or more steel beams to create a substantially continuous surface. The one or more precast deck elements have pockets for receiving connectors that protrude from the one or more steel beams. The method also includes arranging the supporting formwork element to allow the one or more steel beams to bend into a cambered shape to impart compressive stresses to a bottom flange of the one or more steel beams and tension stresses to a top flange of the one or more steel beams and inserting grout into the pockets to hold the cambered shape and to bond the one or more precast deck elements to the connectors and the top flange.

The invention relates to a lowering system (10) for lowering ceiling formworks (70) during the removal of formworks of a building ceiling, comprising a reciprocating piston (14) and a support base (18), and a locking device, wherein the reciprocating piston (14) is slidably mounted in the support base (18), 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 (16), wherein the eccentric lever (16) is rotatably mounted in the pivot bearing, and the reciprocating piston (14) and the support base (18) are supported against each other in the working position by means of the eccentric lever (16).

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

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.

The present invention relates to a method of batch-casting high-fluidity high performance concrete and low-fluidity high performance concrete, wherein the method is capable of batch-casting high-fluidity high performance concrete for forming a girder portion of a bridge and low-fluidity high performance concrete for forming a deck plate portion of the bridge by using a concrete casting apparatus. Accordingly, the construction cost can be reduced and the construction period can be shortened. In addition, because a cold joint does not occur, durability can be improved, and thus the life of the bridge can be increased.

A Bailey beam for reinforcement is composed of Bailey panels, stiffening rods, bolts, anchor bolts, a prestressing tendon and anchorages. The components of the Bailey beam are all prefabricated in a factory, and are assembled and hoisted on site. The prestressing tendon is arranged in a lower chord of the Bailey beam, and is anchored to the stiffening rods at both ends. The Bailey beam slides towards both ends during prestress tensioning. In this case, the Bailey beam is lifted as a whole, and the prestressing force is applied to a lower edge of the Bailey beam, resulting in an inverted arch of structure, closing up of cracks and a decrease in downward deflection. After the completion of the prestress tensioning, sealing is performed by fixing fillers, a sealing steel plate and injecting solidifiable materials.
