摘要:
A structural frame for a building, comprising: adjacent first and second columns; at least one precast concrete floor slab having first and second corner indents located in two adjacent corners and a first elongated edge beam defined between the first and second corner indents, the first elongated edge beam being disposed between the first and second columns such that the first and second columns are received in the first and second corner indents and that the first elongated edge beam abuts the first and second columns; and a first tendon assembly extending between the first and second columns and adapted to be tensioned to compress the first elongated edge beam between the first and second columns, the first tendon assembly including at least one left cable and at least one right cable located symmetrically on either sides of a vertical center plane of the first and second columns.

The present invention relates to a grid deck with shear-resisting plates and the assembly of the grid decks. The shear-resisting plates are pre-cast in the grid deck and protrude from the side surfaces thereof. When the grid decks with shear-resisting plates are assembled, they are laid on the beams with the shear-resisting plates contacting the beams and without the grid decks contacting the beams.

A prefabricated modular reinforced concrete building system includes panel assemblies for foundations, walls, decks, and roofs designed to be built out in a manufacturing facility, shipped to a job site, and filled with concrete. Panel assemblies incorporate a space frame to ensure structural integrity during shipping and during concrete fill. Space frames can include structural columns, rebar mats, spacers, straps, and skin panels. Panel assemblies may be manufactured to contain architectural interior/external finishes, windows/doors, and pre-installed utility distribution systems.
摘要:
A modular construction system and having a plurality of precast concrete caissons, and having a planar floor portion formed on each caisson, downwardly dependent caisson walls surrounding the floor portion, inward and outwardly directed wall surfaces on the caisson walls, with the floor portion and the inward surfaces of the walls together defining a downwardly open hollow space, rebars embedded in the caisson floor portion and in the caisson walls, and, precast concrete locking formations formed on the outwardly directed surfaces of the walls. Also disclosed is a method of precasting caissons, and a method of building construction using precast caisson, and poured in place beams and precast wall panels and poured in place frames.

A unit structural member 20 for building utilizes an M-shaped channel 1 which includes a center U-shaped channel section 2 and right and left U-shaped channel sections 6, 5 continuously formed to share right and left side plates 4, 3 of the center U-shaped channel section 2. A channel trench 7 of the center U-shaped channel section 2 and respective channel trenches 9, 8 of the right and left U-shaped channel sections 6, 5 are opened in opposite directions. The unit structural member 20 for building is constituted with a pair of longitudinal beams 15 formed of long pieces of material of the M-shaped channel 1 in parallel at an established distance and a number of lateral beams formed of short pieces of material of the M-shaped channel 1 in parallel laterally between the parallely-arranged longitudinal beams 15 at established distances in the longitudinal direction of the longitudinal beams 15.
摘要:
A device for forming, reinforcing, joint sealing and edge protecting of a concrete slab panel, wherein the concrete slab panel having a volume, a length, a width, and a surface. The device comprising of an elongated post having a body, a top end and a bottom end with a plurality of elongated grooves extending along the body; a mounting frame has a length, a width and a thickness. The mounting frames having a connecting means to connect the mounting frame to the posts. The present invention eliminates the needs for saw-cut lines for crack inducement and acts as a joint sealer for the concrete slab to relieve the tensile stresses.

摘要:
A floor structure (1) of the type having “crossed reinforcement rods” is described comprising:a) a plurality of composite construction elements (2) arranged side by side and comprising: a1) an elongated body (3) made of expanded plastic material provided with an upper face (3a); a2) at least one reinforcing section bar (4) longitudinally extending in the elongated body (3) and having an upper portion (4c) protruding from the upper face (3a) of the body (3); b) a substantially reticular reinforcement metal structure (10) of a concrete casting (9), supported by the upper portion (4c) of the aforementioned at least one reinforcing section bar (4) at a predetermined distance from the upper face (3a) of the elongated body (3) made of expanded plastic material.Advantageously, the floor structure (1) exhibits lightness and self-supporting characteristics and allows to achieve a substantial reduction of the labor and costs for its manufacture.
摘要:
A structural two-way truss slab of egg-crate form is provided with manufactured pans that have openings in the sidewalls thereof with interconnecting members between the openings. The arrangement is such that the pan can remain in place and thus provide a finished ceiling effect. The system further provides an ability to run air-conditioning, electrical, plumbing and other conduits through the slab itself after the slab has been poured. The slab is structurally equivalent to conventional two-way slabs but is of less gross weight.
