The application discloses an assembled teaching building corridor structure and belongs to the technical field of building structure engineering, which comprises two groups of beam bodies, the bottom end of the beam body is provided with two groups of positioning mechanisms which are far away from each other, the top of the beam body is provided with a limiting groove, the upper part of the two groups of beam bodies is provided with a plurality of groups of prefabricated plate body mechanisms, the bottom end of the prefabricated plate body mechanism is fixedly provided with two groups of limiting blocks, the two groups of limiting blocks are respectively inserted into the corresponding limiting grooves, two groups of through holes are formed in the prefabricated plate body mechanism, the two groups of through holes of the two groups of adjacent prefabricated plate body mechanisms are communicated, a prestressed steel strand is arranged in the plurality of groups of through holes which are communicated and located in the same row, the two ends of the plurality of groups of prefabricated plate body mechanisms are provided with end sealing plates, the bottom of the end sealing plate is provided with a plurality of groups of high-strength bolts II, the two ends of the prestressed steel strand are arranged in the two groups of end sealing plates and are fixedly provided with steel sleeves; the application greatly reduces the single-piece transportation weight of the large-span corridor component, thereby reducing the component transportation cost.

This invention belongs to the field of dialysis powder preparation, specifically relating to a porous, fast-dissolving sugar-containing dialysis powder and a method for preparing the porous, fast-dissolving sugar-containing dialysis powder based on freeze-drying spray. The method includes the following steps: (1) concentrating the sugar-containing dialysis solution to obtain a concentrated solution; (2) atomizing the concentrated solution and freezing the resulting atomized droplets to obtain solid ice crystal particles; (3) sublimating and drying the solid ice crystal particles under reduced pressure to obtain the porous, fast-dissolving sugar-containing dialysis powder. This dialysis powder is prepared using a specific freeze-drying spray technology, possessing the characteristics of porous particles, uniform composition, and rapid dissolution, while significantly reducing transportation volume and cost.
