The invention provides a construction method of a prefabricated multi-ribbed cavity floor, and belongs to the technical field of prefabricated multi-ribbed plate construction. The construction method of the prefabricated multi-ribbed cavity floor comprises the steps of full-hall scaffold building, main keel laying, overall leveling and the like. The construction method comprises the steps that S1, full-hall scaffold building is conducted, specifically, when a full-hall scaffold is built, vertical rods on the upper layer and the lower layer are required to be aligned, the vertical rods are uniformly arranged from the two sides of a cast-in-place ribbed beam, the vertical rods are arranged at the intersection positions of floor elastic bidirectional lines, and scaffold boards are laid under the vertical rods; S2, main keels are laid, specifically, when the main keels are installed, the main keels are required to be arranged in order and not to be inclined, and the two vertical rods at the intersection positions must abut against the main keels; and S3, overall leveling is conducted, specifically, after the main keels are laid, overall leveling is conducted according to control lines, and full-hall scaffold formworks are hoisted on the main keels. The cavity formworks are supported by placing the modularized cavity formworks which are machined and formed in a factory-like mode, and accurate and rapid installation of an upper plate of the prefabricated multi-ribbed plate is achieved by installing limiting square pipes.

The utility model provides a kind of formwork for station internal stand column diameter expansion construction, including steel hoop assembly and wooden formwork assembly;The wooden formwork assembly includes two semicircular templates, and two semicircular templates are formed into a whole circle by surrounding and splicing;The template includes melamine board layer, plywood layer, support batten layer and assembled batten layer from inside to outside in turn;The melamine board layer and plywood layer are fixed by adhesive method, for making the template inner surface even;The support batten layer is arranged around the outer periphery of the plywood layer by adhesive method, for whole circle support;The assembled batten layer is wrapped outside support batten layer for constraining the overall shape of the template;The steel hoop assembly includes a pair of semicircular steel hoops arranged in pairs, a pair of semicircular steel hoops are used for locking outside wooden formwork assembly, and each steel hoop assembly is arranged equidistantly along the length direction of wooden formwork assembly.The template has the advantages of improving construction efficiency and ensuring the appearance quality after stand column diameter expansion.

The utility model provides a fabricated ceiling plate connecting system. Comprising an assembly type suspended ceiling plate, and a step notch is formed in the side edge of the assembly type suspended ceiling plate; the buckle connecting piece comprises a lower hanging edge, a middle edge rib and an upper hanging hook, the lower hanging edge can be inserted into the step notch of the assembly type suspended ceiling plate and is attached to the assembly type suspended ceiling plate, and the middle edge rib can be attached to the back face of the assembly type suspended ceiling plate; the lower part of the triangular hooking keel is provided with at least one pair of lower turning hooks which are turned inwards, and the lower turning hooks can be buckled with the upper hooks of the buckle connecting pieces; the lower portion of the U-shaped hanging piece is provided with a triangular groove matched with the triangular hooking keel in shape, and the upper portion of the U-shaped hanging piece can be connected with a ceiling keel lead screw. And the ceiling joist screw rod is used for fixing and hanging the U-shaped hanging piece on an upper supporting structure of a ceiling. By optimizing the structural design, tight seam splicing and firm installation between the suspended ceiling plates are achieved, meanwhile, a single block is allowed to be rapidly disassembled, replaced or maintained, and the attractiveness of the overall appearance of the suspended ceiling is improved.

The utility model discloses a composite runner brick, and relates to the technical field of composite runner bricks, the composite runner brick comprises a runner brick main body, the two end parts of the outer wall of the runner brick main body are provided with mounting slots, and the mounting slots are internally provided with detachable mounting mechanisms; right-angle plates fixed to a mounting mechanism are arranged on the side walls of the two ends of the runner brick body, hexagonal nuts are fixedly arranged on the inner sides of the right-angle plates located at the ends of the runner brick body, and T-shaped screws are movably connected to the inner sides of the right-angle plates located at the other ends of the runner brick body in an inserted mode. According to the runner brick disclosed by the utility model, the mounting slots are formed in the runner brick main bodies and the mounting mechanisms are arranged in the mounting slots, so that when two runner brick main bodies are spliced, the two adjacent runner brick main bodies can be tightly pressed through the right-angle plates, the hexagon nuts and the T-shaped screw rods between the two adjacent mounting mechanisms; and the splicing seam between the runner brick main bodies is tighter, so that the use quality is improved.

The utility model discloses a building aluminum formwork abutted seam structure which comprises a first aluminum formwork, a second aluminum formwork, a fixing clamping piece and a clamping block, the second aluminum formwork is arranged on one side of the first aluminum formwork, and the clamping block and a clamping groove are arranged on the two sides of the first aluminum formwork and the two sides of the second aluminum formwork respectively. Fixing clamping pieces are evenly clamped into the upper portion of the connecting position of the first aluminum formwork and the second aluminum formwork, limiting grooves are evenly formed in the two sides of the interior of the first aluminum formwork and the two sides of the interior of the second aluminum formwork, reserved grooves are formed in the two sides of the interior of the fixing clamping pieces, and movable plates are evenly arranged in the reserved grooves through elastic pieces. And limiting blocks are arranged on the sides, close to the limiting grooves, of the movable plates. The first aluminum formwork, the second aluminum formwork, the clamping blocks, the clamping grooves and the fixing clamping pieces are installed, a physical barrier is formed through a concave-convex meshing structure, abutted seams are kept tight, the slurry leakage rate is reduced, meanwhile, bolts and tools do not need to be used, and the installation efficiency is improved.
