The invention belongs to the field of buildings, and provides a lamination transitional construction method for a concrete heat insulation curtain wall. The lamination transitional construction method comprises a cast-in-place concrete heat insulation curtain wall construction process and a rear concrete heat insulation curtain wall construction process. The method comprises the steps that a heat insulation plate of the cast-in-place concrete heat insulation curtain wall is fixed, a main structure formwork is erected, an EPS plate is arranged in the position of a cast-in-place concrete panel at the interface of the rear concrete heat insulation curtain wall in a filled mode, concrete is not poured into the cast-in-place concrete panel at the position of the EPS plate temporarily, and an overlapped notch is formed; after the filling wall is poured, a heat insulation plate of the rear concrete heat insulation curtain wall and a heat insulation plate of the cast-in-place concrete heat insulation curtain wall horse tooth stubbles which are staggered; a reinforcing mesh is hung on the heat insulation plate of the rear concrete heat insulation curtain wall, and concrete is smeared on the heat insulation plate of the rear concrete heat insulation curtain wall. According to the method, construction cracks at the interface are scattered within the area of a certain width on the junction of the interface, so that the interface seam width is decreased to be within the tolerance range, and the durability of the concrete heat insulation curtain wall is guaranteed.

The invention provides a bionic heterogeneous integrated bone-cartilage repair bracket and a preparation method thereof. It is a multi-layer structure bracket material, which includes from top to bottom: a hyaline cartilage layer, made of two biological phases of hyaluronic acid and chitosan Capacitive materials are interwoven to form an interpenetrating porous structure; the calcified cartilage layer is composed of chitosan and nano-hydroxyapatite to form an orientation gradient porous structure; the subchondral bone layer is composed of chitosan and nano-hydroxyphosphorus A homogeneous porous structure formed by hybridization of limestone; an integrated multi-layer repair scaffold material with bone-cartilage heterogeneous structure was constructed by in situ synthesis method combined with directional freezing technology. The composite material synthesized by the invention combines the advantages of each component, has good antibacterial properties, biocompatibility, and the effect of in situ inducing two-way regeneration of bone and cartilage; the bonding force of the interface is enhanced, thereby realizing the integration of the scaffold structure change.

The invention discloses an integrated self-driven all-textile gesture recognition data glove, which is characterized in that it includes a glove base, a self-powered strain sensing part, and a flexible and weakly sensitive conductive yarn; the base yarn for weaving the glove base is elastic Insulating yarn, the self-powered strain sensing part is arranged in several sensing areas of the glove base, and the self-powered strain sensing part is connected to the control circuit through the flexible and weakly sensitive conductive yarn. The sensor of the data glove of the present invention is flexible and fibrous under the condition of satisfying the electrical performance, so as to meet the mechanical performance used in the textile weaving process, realize the structural integration of sensor detection and glove material, and improve the possibility of batch production. At the same time, the self-driven passivation of the detection circuit can effectively reduce the burden on the equipment and simplify the circuit, and also avoid the use restrictions caused by charging or replacing the battery.

The invention provides a self-locking valve. The self-locking valve comprises a valve body with an inlet and an outlet; a main channel is arranged in the valve body and provided with a main valve seat; the main channel comprises an inlet side and an outlet side which are located on the two sides of the main valve seat; a main valve element matched with the main valve seat is arranged on the inletside of the valve body; the valve body is internally provided with a reset spring for applying action force on the main valve element to force the main valve element to be closed and further providedwith a back pressure cavity; the back pressure cavity communicates with the outlet side through a control channel; the control channel is internally provided with a control valve seat and a corresponding control valve element; the valve body is provided with an electromagnet used for driving the control valve element to act; the electromagnet comprises an armature and a valve rod arranged on the armature; the armature is provided with a mounting hole extending in the reciprocating moving direction of the armature; and the valve rod is connected, fastened and assembled in the mounting hole through threads.

The invention provides a composite sandwich structure, comprising a main body structure (1) and a concentrated-tip-force diffusion block (2), wherein the main structure (1) comprises a first upper panel (101), a first lower panel (102) and a main core material (103) located between the two panels; the concentrated-tip-force diffusion block (2) and the lower panel (102) are glued and jointed via aglue film to form a wedge-shaped member; and the wedge-shaped member is laid between the first upper panel (101) and the second lower panel (102). The composite sandwich structure is molded by pressurized curing in a baking oven. According to the composite sandwich structure and the manufacturing method thereof in the invention, one end can bear concentrated force; and the manner of combined-structure secondary curing is employed, so the composite sandwich structure can be cured and molded in the baking oven, cost increase due to curing in an autoclave is avoided, and a low-density core material is protected from collapse under the action of high pressure of the autoclave.
