The invention discloses a TSV solid-phase hole filling interconnection method and structure, and relates to the technical field of semiconductor packaging. The TSV solid-phase hole-filling interconnection method comprises the steps of S1, silicon through hole etching and deposition, S2, copper column insertion and fixation, S3, surface treatment and interconnection construction and S4, electrical testing and process feedback, a complex electroplating production line is abandoned, the through holes are filled through plastic deformation of the solid copper columns, the inherent hole and seam problems of an electroplating method are avoided, and the TSV solid-phase hole-filling interconnection method is suitable for large-scale production. The high-purity solid copper columns are high in mechanical strength and are tightly and mechanically interlocked with the inner walls of the through holes through plastic deformation, and the anti-fatigue capacity of the interconnection structure under the thermal cycle load is improved by combining the insulating layer and the barrier layer, so that reliable vertical interconnection is obtained, thermal expansion coefficient mismatch of copper and silicon is effectively avoided, and the reliability of the interconnection structure is improved. Stress is generated on the interface in the electroplating process and the subsequent thermal cycle.

The utility model discloses a direct-touch type ground splicing structure, and relates to the field of ground stone installation, the direct-touch type ground splicing structure comprises a fine aggregate concrete layer, a thick daub bonding layer and stone plates which are sequentially laid on a reinforced concrete floor layer from bottom to top, and expansion joint strips are arranged between the stone plates; an expansion joint strip is arranged on the surface of the stone plate, an auxiliary assembly used for auxiliary positioning is arranged outside the expansion joint strip, an arc groove is formed in one side of the surface of the stone plate, and arc plates matched with the arc groove are fixedly connected to the two sides of the expansion joint strip correspondingly. When the supporting plate is located in the positioning piece, the supporting plate is opened through the elastic force of the torsional spring and abuts against the inner wall of the positioning piece, the expansion joint strip is clamped, the position of the expansion joint strip is more stable, and position deviation caused after the expansion joint strip is impacted can be prevented.

The utility model belongs to marble composite board field especially, it is a kind of multilayer co-extrusion weather-resistant organic artificial marble composite board, aiming at the spacing control difficulty of existing marble composite board: uneven gap when stone slab splicing, affect overall flatness and aesthetic property;Risk of thermal expansion and cold shrinkage: the problem of insufficient installation stability, present and propose the following scheme, including stone slab main part, the stone slab main part includes base plate, the upper layer resin plate of base plate top is sequentially laminated and bonded, lower layer resin plate, reinforcing plate and rubber plate, the second installation slot of accommodating lower layer resin plate, reinforcing plate and rubber plate is set in the upper layer resin plate bottom, in the utility model, when four stone slab main parts are spliced, connecting block realizes automatic alignment by mutual interference, ensure that gap is even;Connecting block thickness is much smaller than stone slab main part, after installation, the side connecting block can be quickly removed through easy-to-disassemble component (connecting broken groove, first strip broken groove, second strip broken groove), form reserved gap.

The utility model belongs to the field of building construction technology, and disclose a form plate structure for construction concrete column, include: a plurality of form plates, a plurality of support frames are supported in the outside of a plurality of form plates respectively, and a plurality of constraint pieces are arranged in the corner position of two adjacent form plates respectively, every constraint piece includes two installation ports, two first splicing pieces and second splicing piece, the second splicing piece is provided with two splicing parts, and two splicing parts embed two installation ports respectively and splice with corresponding first splicing piece respectively, to realize the connection and fixation of two adjacent form plates. The utility model utilizes the support frame to support the form plate, so that the form plate is stable and does not move during pouring construction, two adjacent form plates are connected and fixed through the constraint piece, and are arranged at the corner of two adjacent form plates, so that two adjacent form plates are closely attached and difficult to separate, to cope with the lateral pressure when pouring concrete, and the corner gap can be effectively avoided.

The utility model discloses a kind of dismounting floor for sports venue, by a plurality of floor units splicing, floor unit includes the panel, bearing plate, combined keel layer and shock-absorbing layer sequentially arranged from top to bottom, the periphery side of panel is provided with lock catch structure, the both ends of bearing plate are respectively provided with semicircular tenon and the semicircular groove matched with semicircular tenon, adjacent floor unit is connected by magnetic attraction component;Magnetic attraction component includes switch type magnetic base and ferrous suction accessory, switch type magnetic base is arranged in the side edge of bearing plate bottom surface, ferrous suction accessory is L-shaped flake structure, is formed by integral fixed part and suction part, fixed part is arranged in the side edge of bearing plate bottom surface another side, switch type magnetic base and ferrous suction accessory's suction part magnetic attraction connection;When the dismounting floor is subjected to stronger impact force, adjacent floor unit is connected by the strong magnetic connection of switch type magnetic base and ferrous suction accessory's suction part, can effectively avoid the phenomenon that floor is opened seam.
