The invention discloses a steel-concrete slab-column structure system which comprises a concrete layer and a node framework structure of steel girders and steel columns and used for supporting the concrete layer, wherein the framework structure comprises a plurality of steel columns, steel girders connected between every two steel columns and connection assemblies used for connecting the steel columns and the steel girders. The steel beams comprise top flange plates, bottom flange plates and webs arranged between the top flange plates and the bottom flange plates and used for supporting the top flange plates and the bottom flange plates. The concrete layer comprises a prefabricated concrete layer arranged on the lower flange plates and a cast-in-place concrete layer arranged on the prefabricated concrete layer, and the cast-in-place concrete layer is formed by pouring concrete and a two-way reinforcement fabric. The steel-concrete slab-column structure system is convenient to operate on site, large in rigidity, strong overall and good in the anti-seismic property.

The invention provides a no-avoidance three-dimensional parking garage having the advantages of safety and convenience for parking and no need of embedding guide rails. The no-avoidance three-dimensional parking garage comprises guide rails and vertical column devices, wherein the vertical column devices comprise mobile cars capable of walking on the guide rails; vertical columns capable of rotating are arranged on the mobile cars, and are provided with lifting bases capable of being lifted on the vertical columns; and trays for car parking are fixed on the lifting bases. The no-avoidance three-dimensional parking garage further comprises a base; the guide rails are respectively arranged at the left and right ends of the base; and the vertical column devices are respectively arranged on the guide rails at the left and right ends. The no-avoidance three-dimensional parking garage is provided with the left and right two vertical column structures, and the upper/lower-layer parking can be finished outside the garage without needing to enter the lower-layer garage, so that the parking is safe and convenient; the no-avoidance three-dimensional parking garage is provided with a parking video device and a remote controller for use convenience; and the vertical column devices at the left and right ends are combined as a whole by the base without needing other counterweights, and the guide rails are directly arranged on the base, so that the strength can be guaranteed without embedding the guide rails.

The invention discloses an amorphous alloy transformer with a circular iron core and a short-circuit-resistant structure, and a manufacturing method thereof. Each iron core column is a circle formed by combining four single iron cores which are the same in structure and have right-angled stepped sections, and side columns on the two sides are semicircles formed by combining two right-angled stepped single iron cores which are the same in structure; and coils are mounted on the three main columns to form a transformer body. The method comprises the following steps: adopting a three-phase five-column structure; designing a manufacturing tool; optimally designing upper and lower clamping piece structures; assembling the main column iron core and the side column iron cores by using the manufacturing tool, opening the openings of the main column iron core and the side column iron cores, vertically placing the lower parts of the main column iron core and the side column iron cores on the manufacturing tool in a manner that the openings face upwards, and sleeving the coils into the iron cores from top to bottom after the iron cores are arranged; and after the iron core lamination is finished, installing the upper clamping piece and the lower clamping piece, and overturning the transformer body once to make the iron cores opened downwards and suspended on the coils. The production timeis shortened, a large amount of manufacturing cost is saved, the coil sudden short circuit passing rate is increased, and the state grid high-standard requirement is better met.
