The application discloses a full-wrapping concrete truss structure and a construction method thereof, and belongs to the technical field of building structures. The full-wrapping concrete truss structure comprises a steel pipe truss assembly arranged between a plurality of steel plates, a wrapping assembly arranged outside the steel pipe truss assembly, and a concrete layer arranged outside the wrapping assembly. The construction method comprises the following steps: S1, preparing a top chord, a bottom chord, a vertical rod and a horizontal rod, wrapping the rods with a reinforcing mesh and welding to obtain a steel pipe truss shell; S2, arranging a diagonal web member assembly inside the shell and arranging a connecting mesh outside the shell to form a steel pipe truss monomer; S3, bolt connecting a plurality of monomers and bolt connecting the steel plates and the monomers at edges to form a steel pipe truss structure; and S4, vibrating the steel pipe truss structure after concrete partition pouring to obtain the full-wrapping concrete truss structure. The application can realize full wrapping of the steel pipe, ensure that the concrete layer is tightly bonded with the steel pipe, and improve the stability and safety of the structure.

The utility model belongs to the technical field of laser processing, and relates to a laser cutting machine tool. The laser cutting machine tool comprises a tool body and a dust extraction system, the tool body comprises an inner supporting plate, an outer supporting plate and a bottom plate, the outer supporting plate is fixed to the bottom plate, reinforcing ribs are arranged between the inner supporting plate and the outer supporting plate, the inner supporting plate and the outer supporting plate are fixedly connected with the reinforcing ribs respectively, and the dust extraction system is installed on the tool body and comprises a dust extraction pipeline. A part of the dust suction pipeline is embedded into the bed body, the top face of the dust suction pipeline is fixedly connected with the inner supporting plate, one side face of the dust suction pipeline is fixedly connected with the reinforcing ribs, and the side face, away from the reinforcing ribs, of the dust suction pipeline is provided with a suction opening and protrudes out of the inner supporting plate. According to the technical scheme provided by the invention, the laser cutting machine tool can have higher dust extraction efficiency.

The utility model relates to a mold for injection molding of a product, which comprises a front mold core, a rear mold core and an injection molding runner, and the rear mold core is in butt joint with the front mold core to form an injection molding cavity between the rear mold core and the front mold core; the injection molding runner is communicated with the injection molding cavity, a cavity sprue formed by connecting the injection molding runner and the injection molding cavity is located on the ground side of the injection molding cavity, and the mold is further provided with a first exhaust hole communicated with the injection molding cavity. The cavity sprue is located on the ground side of the mold, glue is fed from the ground side and then enters the injection molding cavity, melt is gradually stacked layer by layer upwards, air in the injection molding cavity can be effectively exhausted, and bubbles are not prone to occurring after a product is formed. Ground side glue feeding is adopted, the periphery of the cavity pouring gate is filled with melt at the beginning, the melt is tightly attached to the surface of the injection molding cavity, after the melt around the cavity pouring gate is cooled and formed, CD grains are not prone to being formed when the melt is continuously injected, and the quality problems that the appearance face is rough, wrinkles or the CD grains are obvious are effectively solved.

The invention provides a high-stability metro station enclosure structure and a construction method thereof, and belongs to the technical field of metro station enclosure structures, the high-stability metro station enclosure structure structurally comprises a deeply-buried anti-seepage shear wall, an enclosure base platform is poured on the top surface of the deeply-buried anti-seepage shear wall, and an enclosure shear wall is vertically poured on the right side of the top surface of the enclosure base platform; a plurality of anti-outward-pushing edges are longitudinally poured on the left side face of the enclosure base station at intervals, tension longitudinal edges are longitudinally poured on the outer sides between the anti-outward-pushing edges, and a plurality of H-shaped steel beams are deeply buried at the lower ends of the tension longitudinal edges at intervals. In addition, as the bottom of the abutment generally does not have a lateral water seepage prevention function, transverse water seepage of the bottom surface of the abutment is caused.

The utility model discloses a high-magnification overcurrent row and a battery module. The battery module comprises a mounting frame, the mounting frame comprises two side plates and two end plates, and a mounting space is defined by the two side plates and the two end plates; the plurality of battery cells are uniformly arranged in the mounting space; and the high-magnification overcurrent row is connected with the plurality of battery cells in a welding manner. The high-magnification overflowing row comprises an integrated component, wherein the integrated component comprises a main body part and a connecting part; the connecting part is located at the end of the integrated component; the connecting part is narrower than the main body part; the metal sheets are stacked on the connecting part, and the connecting part and the metal sheets are made of different materials. As the width of the connecting part is smaller than that of the main body part, the cross section of the connecting part can be increased by stacking the metal sheets at the connecting part, so that the requirement of high-magnification overcurrent is met.

This invention provides an atomizer and an electronic atomizing device. The atomizing device includes an atomizer comprising an oil cup and an atomizing component. The atomizing component is installed at the bottom of the oil cup and forms a liquid storage chamber with the oil cup. The atomizing component includes a support and a flat oil guide body and a sheet-shaped heating element vertically or inclinedly disposed inside the support. The oil guide body has opposing liquid absorption and atomization surfaces, and the heating element is disposed on the atomization surface of the oil guide body. An air outlet channel is formed within the oil cup. The atomizing component has an atomization chamber located on one side of the atomization surface and a connecting channel connecting the atomization chamber and the air outlet channel. The wall of the connecting channel is recessed away from the central axis of the atomizer to form a clearance cavity. The clearance cavity formed by this design can increase the cross-section of the connecting channel, saving material, thereby allowing the overall thickness of the atomizer to be thinner while ensuring smooth airflow.
