The invention discloses a fabricated frame square timber sash-graphite polyphenyl-reinforced foamed ceramic plate combined wallboard and a manufacturing method thereof, which are mainly used as a peripheral wall panel of a light steel frame structure. The wood-wood composite board is formed by assembling an inner leaf frame square wood frame lattice and bamboo plywood combined inner leaf board, an outer leaf frame square wood frame lattice and reinforced foaming ceramic board combined outer leaf board and a sandwich graphite polystyrene board. The inner and outer leaf frame square timber sash is formed by connecting square timbers through node steel plates. The reinforced foamed ceramic plate is formed by compositing a foamed ceramic plate with a decorative surface layer and a high-ductility mortar plate with a shear key, and the high-ductility mortar plate is composed of a built-in steel wire mesh with the thickness not smaller than 20 mm, steel plate strips welded to the periphery of the steel wire mesh and a swallow tail meshing type frame on the periphery of the steel wire mesh. The assembly type frame square timber sash-graphite polyphenyl-reinforced foaming ceramic plate combined wallboard has the integrated functions of structure, heat preservation, decoration and enclosure, has the technical characteristics of light weight, good anti-seismic and fire-resistant performance and convenience and rapidness in assembly and construction, and has two anti-seismic defense lines.

The utility model discloses a strip type CFRP cloth hoop concrete beam which comprises CFRP longitudinal bars, CFRP cloth strips and steel stirrups. The CFRP cloth strips are made of carbon fiber cloth and epoxy resin glue and replace traditional steel bar stirrups to help concrete to resist shear, the three steel bar stirrups are arranged at the two ends and the midspan of a beam, only play a role in fixing a steel bar framework and have little help to structural stress, and the CFRP cloth strips are folded three times in the width direction to form a W-shaped section. A self-locking structure is formed through meshing of the wave crests and the wave troughs and vertically surrounds the outer sides of the longitudinal bars to form closed anti-shearing rings, and finally the CFRP cloth hoop steel bar framework is formed. Interface bonding is enhanced through folding self-locking and epoxy resin synergistically, the shear bearing capacity and corrosion resistance are remarkably improved, and the composite plate is suitable for corrosion environments such as ocean engineering and chemical engineering plants and has the advantages of being light in weight, easy to assemble and low in maintenance cost.

The utility model relates to an equal-strength steel truss reinforcing structure of a structural damage PC box girder, and belongs to the technical field of building structure reinforcing. Comprising a steel truss with the same strength as a PC box girder, and the steel truss is of a cuboid space steel truss structure; a plane truss is arranged on the face, opposite to the steel truss, of the web plate, and the plane truss and the steel truss are fixed to the two sides of the web plate through opposite-pull screws. The steel truss is located on the inner side or the outer side of the web. Anchor bolts and steel gaskets are further arranged on the opposite-pull screws to reinforce and fix the steel trusses and the plane trusses and anchor the opposite-pull screws. And the opposite-pull screws are arranged at the joints of the chord members in the steel truss. A steel-concrete transition connecting section is arranged at the end part of the steel truss and is fixed through an opposite-pull screw rod; and the number of the opposite-pull screws on the transition connecting section is determined according to the tensile force borne by the steel truss chord member and the tensile force which can be borne by a single opposite-pull screw. The equal-strength steel trusses are arranged on the box girder in the damaged area, and meanwhile small original structure damage and a strong reinforcing effect are guaranteed.

The invention discloses an L-shaped wooden column-hole-hidden graphite hardwood-graphite layer-along column foundation stone seismic isolation system which is mainly used for seismic isolation and self-resetting of the bottom of a wooden structure L-shaped wooden column. The shock insulation system is composed of an L-shaped wooden column, three pieces of hole-hidden graphite hardwood, three pieces of concave spherical surface column foundation stones with limiting edges, a graphite layer and three annular tempered glass sealing plates. The L-shaped wooden column is formed by connecting three round timbers through square timber ladders and bamboo plywood. The hole-hidden graphite hardwood is composed of a convex spherical section, a thick cylindrical section, a graphite-hidden hole and a thin cylindrical connecting key which are integrally processed. The graphite layer can reduce the friction force between the convex spherical surface of the hole-hidden graphite hardwood and the concave spherical surface of the column foundation stone. The concave spherical surface of the column foundation stone can enable the L-shaped wooden column to reset automatically after an earthquake, and the limiting edge of the column foundation stone can limit excessive displacement of the bottom of the L-shaped wooden column in the vibration process. And the annular toughened glass sealing plate can be sealed and waterproof. The seismic isolation system has the advantages that seismic isolation at the bottoms of the L-shaped wooden columns reduces the seismic action of an upper structure, and self-resetting after an earthquake achieves structural toughness seismic resistance.

The utility model relates to prefabricated building technical field discloses prefabricated building beam column joint connecting piece, including beam column, the outside fixed connection of beam column has fixed frame, the periphery of fixed frame all is fixedly connected with connecting block, the outside sliding connection of connecting block has H type steel, the outside sliding connection of H type steel has bolt, the outside sliding connection of H type steel has damping assembly, damping assembly includes rotating block, the inside rotation of rotating block is connected with rotating board, the top fixed connection of rotating board has spring, the top fixed connection of rotating board has damper, the outside sliding connection of H type steel has connecting plate. In the utility model, realize the installation effect of H type steel, rely on damper and spring synergic energy consumption, have the advantage that assemble convenient, maintain convenient, wide application range and can optimize the whole life cycle cost.
