The invention relates to a method for displacing a ceiling formwork (10) for a nearest concreting section (9), wherein first (11) and second (12) supporting devices for supporting the ceiling formwork (10) are arranged below the nearest concreting section (9). Said supporting devices each have a shuttering position (EP) and a stripping position (AP), wherein the ceiling formwork is raised to a concreting level in the shuttering position (EP) and lowered relative to the concreting level in the stripping position (AP). The first supporting device (11) is moved into the stripping position and the second supporting device is moved into the shuttering position, and a collision protection element (15, 15) is arranged between the second supporting device (12) and an end face (17, 17) of the ceiling formwork (10) when the end face (17, 17) of the ceiling formwork (10) strikes the second supporting device (12) after passing over the first supporting device (11), so that the collision protection element (15, 15) forms a flank (15a) rising in the displacement direction (VR) for guiding the ceiling formwork (10) in the displacement direction (VR). The end face (17, 17) of the ceiling formwork (10) is then liftedguided by the collision protection element (15, 15)to the concreting level so that the ceiling formwork (10) passes over the second supporting device (12).

The invention relates to a supporting device (14, 14, 14, 15, 15, 15) for the construction industry. Said device has a fixing element (14a, 15a) which rests against a side wall (2a) and is fixed at a fixing point (FP) of the side wall (2a). Said device also has a cantilever (14b1, 14b2, 14c; 15b1, 15b2, 15c-15e) which is connected to the fixing element (14a, 15a) and, when the fixing element (14a, 15a) is in the fixed state, projects from the side wall (2a) such that a load element (10) can rest against a bearing point (AP) of a bearing element (14b1, 14b2; 15b1, 15b2) of the cantilever. The load element (10) can now be displaced in a displacement direction (VR) substantially parallel to the side wall (2a) relative to the cantilever and, when the load element (10) rests against the bearing element of the cantilever, the cantilever is coupled to the load element (10) such that a displacement force component acts on the cantilever in the displacement direction (VR) when the load element (10) is displaced, said displacement force component resulting in a torque on the cantilever. The device also comprises an anti-rotation element (16, 16, 17, 17) which is connected to the cantilever. When the load element (10) is displaced, another end of the anti-rotation element should rest against the side wall (2a) in order to counteract the torque.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

A pre-fabricated deck panel includes a plurality of corrugations extending transversely along a length, and a pre-fabricated end dam on at least one end of the panel. The end dam extends to a height of the corrugations. The panel may further include at least one pre-fabricated side edge dam on at least one side of the panel. The side edge dam extends to height above the corrugations.

A steel-concrete composite bridge deck slab using inverted U-shaped shear connectors and a method for constructing the same are provided. The steel-concrete composite bridge deck slab includes a bottom steel plate and a bridge deck concrete layer, wherein inverted U-shaped perforated steel plate units are arranged on an upper surface of the bottom steel plate, and bar-mat reinforcements are arranged at upper ends of the inverted U-shaped perforated steel plate units.

A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.

The bridge construction system and method according to the present invention provides a lightweight, efficient, economical, long-lasting, and easily implemented composite steel structure that can be filled with concrete in place for the construction of pedestrian and smaller road bridges, specifically those found in rural areas. The bridge construction system of the present invention is unique in that it is a steel-frame reinforced composite bridge with decking and rebar caging that provides a permanent, non-removable form for poured-in-place concrete. The composite nature of the bridge allows for installation of the bridge to take place in one day, while the entire process from site preparation such as grading and excavation to cleanup takes a week or less. The quick installation of the bridge is designed to have a minimally invasive impact on the surrounding environment.

A platform panel is disclosed. The panel includes a core having a top surface and a bottom surface. The core has a composite skin disposed on the top surface and the bottom surface of the core. Further, recessed pockets having a fastener port. Moreover, the panel includes a first hinge member disposed on a first side of the core, and a second hinge member disposed on an opposing side of the core in relation to the first hinge member.

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.
