This invention provides a method for constructing ultra-high-rise buildings with ultra-long span simply supported floor slabs without support, comprising: hoisting and connecting structural steel columns; hoisting structural steel beams and connecting them to the corbels of the structural steel columns; laying floor slabs; welding studs to the top of the structural steel beams to fix the galvanized bottom formwork of the floor slabs; installing lower reinforcing bars; installing additional lower reinforcing bars on the floor slabs at the breaks or perpendicular intersections with the structural steel beams; installing upper reinforcing bars; installing additional upper reinforcing bars on the floor slabs at the breaks or perpendicular intersections with the structural steel beams; and pouring concrete. This invention eliminates the need for traditional full-span scaffolding support, enabling the construction of reinforced concrete for simply supported floor slabs exceeding the maximum unsupported span at high altitudes. It shortens the construction period, saves on scaffolding material usage and erection costs, avoids instability in ultra-high support scaffolding, ensures safety during high-altitude operations, fully utilizes the original design's upper and lower chord reinforcing bars and additional upper and lower reinforcing bars, requires no additional construction materials, and is environmentally friendly.

The utility model relates to outer rotor motor technical field discloses a riveting transmission structure of outer rotor brushless motor for electric treadmill, including outer rotor casing and the end cap of setting in the end part of outer rotor casing, the end part of outer rotor casing exceeds the end face of end cap and exceeds the portion and forms the limit rivet point abutting to the outer end face of end cap through riveting cutting inwards bending, the outer end face of end cap is equipped with the limit rotation clamping groove of rivet point jointing for preventing end cap and outer rotor casing from generating relative rotation, the riveting transmission structure of outer rotor brushless motor for electric treadmill of the utility model, the limit rivet point of inwards bending can carry out axial location to the end cap on outer rotor casing, and the jointing cooperation between limit rivet point and limit rotation clamping groove can play the effect of limiting rotation, thereby effectively improving the connection stability between end cap and outer rotor casing. The limit rivet point formed through riveting cutting can improve the processing efficiency and the utilization rate of outer rotor casing raw material, thereby reducing the production cost.

The utility model provides a lockable ball valve, include: valve body, the inside of valve body is provided with from top to bottom coaxial connection's electronic lock head, valve stem, valve ball, the lower part of valve body contains the threaded connection valve body one, valve body two, the both sides of valve ball are provided with a PTFE valve seat respectively, every PTFE valve seat is respectively embedded in valve body one, valve body two, the utility model structure is simple and reasonable, and the integrity is strong, through the design of the upper cavity structure of valve body, combines the special electronic lock head structure design, can prevent others unauthorizedly open pipeline valve privately, ensures the safe operation of pipeline system, the upper cavity of valve body can place electronic lock head, can install hand wheel, not only can realize the unlocking and unlocking of valve through electronic lock head, but also can install hand wheel and use as ordinary ball valve, realize one valve two uses, not only saves equipment procurement cost, but also saves installation cost and time, good applicability, it is favorable to popularization and application.

This utility model discloses a common-enclosure busbar, including an enclosure, an upper bracket, and a lower bracket disposed within the enclosure. Each upper and lower bracket is equipped with an insulated support block. The upper and lower brackets support both ends of the copper busbar conductor via the support blocks. By setting the upper and lower brackets within the enclosure and respectively providing support blocks, and using insulated support blocks to support both ends of the copper busbar conductor, the copper busbar conductor only contacts the support blocks. Since the support blocks are made of insulating material, insulation performance is guaranteed without additional insulation treatment, adapting to various insulation requirements. During installation, the copper busbar conductor can be easily pushed in by aligning it with the support blocks of the upper and lower brackets. Similarly, during disassembly, the copper busbar can be quickly pulled out, reducing workload and eliminating the need for hardware, fasteners, and screws, thus saving on corresponding materials and installation costs.

This utility model belongs to the field of shipbuilding, specifically a steel plate cutting device for shipbuilding. It includes a ventilation pipe, with uniformly distributed filter pipes fixedly connected to the inner side of the top of the ventilation pipe. A first sealing ring is fixedly connected to the middle of the inner side of the filter pipe, and a filter screen is fixedly connected to the bottom of the first sealing ring. A cleaning component is provided inside the filter screen, and a second sealing ring is fixedly connected to the bottom of the filter screen. The second sealing ring is fixedly connected to the filter pipe, and a storage component is provided inside the second sealing ring. This utility model provides a steel plate cutting device for shipbuilding that collects dust through a storage pipe, and simultaneously allows for cleaning of the dust inside the storage pipe by removing a second bolt, eliminating the need for purchasing and installing an external dust removal system. Furthermore, it simplifies the production line layout, avoiding complex operation and equipment coordination problems caused by dust removal equipment.
