The invention relates to a brand-new construction method of a mixed combined girder cable-stayed bridge. After the construction of the main tower, auxiliary piers, side piers, main bridge side span concrete beams and approach bridges, the mid-span steel girder members and prefabricated concrete decks of the cable-stayed bridges are transported from the ground via the approach bridges and main bridge side spans to Midspan. The truck crane also moves from the ground through the approach bridge and the side span of the main bridge to the front end of the completed combined beam in the mid-span, and lifts the components on the girder truck for cantilever construction. The bridge is hung with stay cables and tensioned for the first time. Construct the wet joints of the bridge deck, form the mid-span combined beam of this section, and repeat the construction until the main structure of the cable-stayed bridge is completed, and the bridge deck and the auxiliary structure of the main tower are constructed. The invention adopts the automobile crane, which can adapt to the construction of the wide bridge, and is convenient and flexible in use, and saves labor;

A method for erecting structures composed of rammed-earth. A method of rammed-earth building construction is disclosed wherein walls are post-tensioned to enhance the ability of the wall to receive lateral loading without failing in tension.

Post-tensioning rods are anchored to a concrete footing, and temporary forms erected alongside the footing. A protective sleeve is disposed around each post-tensioning rod. An earthen mixture is placed between the forms and around the sleeves, and rammed by compaction in a series of stacked courses. When the rammed-earth wall has obtained the desired height, it is topped with a concrete bond beam through which the post-tensioning rods extend. Using the bond beam as a brace against which a retaining plate may push, retaining plates are disposed upon the bond beam and around the threaded upper ends of each rod. A nut is threaded upon each rod and tightened against the retaining plate to draw the rod into tension. The torque applied to the nut thus loads the wall in compression via the plates and bond beam. Thus compressed, the rammed-earth wall is less susceptible to tension failure.

Masonry walls of buildings supported on concrete foundations are strengthened against destructive wind and seismic forces by spaced elongated members inserted inside the hollow masonry walls. The spaced elongated members are secured to the continuous masonry bond beam and the foundation. Tension means at the top of the masonry wall make the elongated members taut creating a continuous tension load path from bond beam to the foundation.

A pre-cast concrete wall system that incorporates a truss ledge for positioning a building floor system at a below-grade location.

A floor truss system can be supported on the upper bond beam with the truss ledge forming a concrete below-grade surface externally of the floor trusses. Galvanized steel stud facings incorporating fold-up reinforcing bar supports are used on the interior surface of the vertical wall beams. Insulated access holes are formed through the vertical beams for the passage of wiring and plumbing behind the wall finish to be fastened to the stud facings.

The invention discloses a main beam side-span closure construction method for a bond beam cable-stayed bridge. Suspension splicing installation is not conducted on a side-span tail end beam section. A tail-section steel beam is spliced and constructed through a landing steel pipe support. End cross beam reinforced concrete is constructed through a scaffold. A side-span closure opening is additionally formed between the side-span tail end beam section and a sub-tail end beam section. Through reverse pre-deviation of an end cross beam (including a support top board) and jacking reset of the end cross beam, the problem about matching of a bond beam and a standard bond beam section after the end cross beam is poured is effectively solved.

A method of constructing a masonry infill in a load bearing structure comprises the steps of: laying one or more courses of masonry (7) in the infill space; partitioning off a casting space having as its base the then uppermost course of masonry (22); the casting space extending from one side of the infill space to the other; positioning reinforcing material (14) in the casting space; securing an end of the reinforcing material to the load bearing structure; filling the casting space with concrete (20), and laying one or more further courses of masonry on top of the filled casting space. The reinforced concrete forms a bond beam which strengthens the masonry. The reinforcing material may be rebar, secured to a load-bearing frame of the building by a cleat (16) having pockets (12) for reception of the rebar ends. Optionally the reinforcement may be tensioned, to pre-stress the bond beam. The bond beam may also be used to strengthen bonded, load-bearing masonry panels in bending, without being secured to an adjacent load-bearing structure.

Disclosed is a modular poured concrete wall system that addresses the needs not optimally met by the prior art, where inexpensive small light interlocking forms are quickly and readily assembled, to produce the desired aesthetically pleasing appearance of a brick wall system. The forms remain in place as part of the final structure and finished surface of the walls. Thus, a footer track assembly is affixed to a standard concrete footer or foundation. Then the modular forms are assembled upon the footer track, stacked together to produce the appearance of a brick wall. As each row or two of forms are assembled, the forms are filled with concrete. Following the concrete pour, additional forms are assembled on the top of the prior forms, to produce additional rows. By repeating this process, the full height of the wall can be quickly reached. The method may include steel rebar, such as for horizontal bond beams and for vertical strength. In an alternative embodiment, curved modular forms may be assembled to produce a circular column, where the exterior surface is finished as a decorative brick appearance.
