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.

This utility model discloses a waterproof computer power supply, belonging to the field of computer power supply technology. It includes: a power supply body with a storage groove inside; a wiring harness groove, a side groove, and a heat dissipation groove on one side of the power supply body; a power cord inside the wiring harness groove; and a connecting wire harness on the other side of the power supply body. This utility model incorporates a pull-out sealing mechanism. This design utilizes a pull-out structure to achieve sealed protection for the power supply. When the power supply is in use, the pull-out structure can be pulled out and quickly positioned according to the usage area, ensuring normal operation of the power supply. When not in use, it can seal the power supply, preventing external moisture and water from entering, thus extending the power supply's lifespan and safety, and improving its practical application.
