The invention belongs to the technical field of building construction, and discloses a construction method of a high-altitude super-large-span negative-curvature flexible steel roof structure. Comprising the following steps that the periphery of a negative curvature flexible steel roof of a radial net structure formed by longitudinal main beams and transverse secondary beams is connected with four steel roof trusses of an east truss, a south truss, a west truss and a north truss correspondingly; the temporary supporting jig frame and the transverse main beam are used as temporary pulling knots; two transverse main beam supporting jig frames are installed, and positioning and splicing are conducted according to the distribution positions of transverse main beams; the transverse main beams are welded and spliced into a whole at the positions of the transverse main beam supporting jig frames; socket type expansion joints used for releasing deformation in the east-west direction are arranged on the transverse secondary beams at the ends of the south side and the north side of the longitudinal main beam. And after the longitudinal main beams and the transverse secondary beams of the roof are all installed, the jig frame unloading process is carried out, and the accurate and efficient installation process of the whole roof truss is completed. The whole unloading process can be precisely controlled, and construction safety is ensured.

A prefabricated multi-ribbed channel-shaped plate is provided with staggered first horizontal ribs, second horizontal ribs, first vertical ribs and second vertical ribs at the lower part of the plate body, the first horizontal ribs are provided with bending forming ribs and prestressed steel wires, the second horizontal ribs are provided with first U-shaped forming ribs and prestressed steel wires, and the second vertical ribs are provided with second U-shaped forming ribs, and the connection strength performance of the horizontal ribs and the vertical ribs is improved through the horizontal ribs and the vertical ribs in the plate body. The multi-rib structure is adopted, the two side edges are half ribs, the middle part is a full rib, a spatial grid structure is formed, the overall stiffness and bearing capacity are enhanced, the integrity and deformation resistance of the multi-ribbed plate are improved, and the multi-ribbed plate is suitable for large-span heavy-load working conditions, such as industrial plants, large public buildings and the like, and can bear a large live load. In buildings, such as residences and office buildings, which are sensitive to layer height, the multi-ribbed plate can reduce the structural height, improve the building headroom, realize the design of no column and no wall in a large space, and improve the spatial experience. Not only can the plate bottom cracking and deflection deformation problems be greatly reduced during construction and use, the user experience is improved, but also the needs of different users are met.

The utility model discloses a poultry egg husking device, which belongs to the technical field of poultry egg processing equipment, and comprises a pressure conveying roller and two husking rollers which are respectively and rotatably arranged on a rack, each husking roller comprises a core shaft which is rotatably arranged on the rack, each core shaft comprises a transmission end and a mounting end, a transmission gear is fixedly arranged at each transmission end, and a transmission shaft is fixedly arranged at each mounting end. The transmission gear is sleeved on the mandrel, the mounting end is sleeved with a rubber sleeve, the rubber sleeve and the pressing conveying roller jointly form an effective poultry egg shelling area, and the shaft diameter of non-shelling effective areas on two sides of the rubber sleeve is larger than the diameter of the mandrel at the position of the rubber sleeve. The poultry egg shelling roller solves the technical problems that a shelling roller is poor in bending resistance, and poultry eggs are damaged due to the fact that the poultry egg shelling roller is prone to deformation during shelling, and is widely applied to poultry egg shelling.

The utility model relates to the technical field of building construction, concretely relates to a support variable cross section channel shape composite component, including panel and two strip shape, two the strip shape fixed in the position of the two sides bottom of the panel along the length direction, the strip shape includes side plate section and two eaves beam sections, two the eaves beam section is fixed in the both ends of side plate section, and the thickness of eaves beam section is greater than the thickness of side plate section. The utility model forms eaves beam section through thickening the vertical edge both ends position of panel, makes its eaves beam section have certain thickness, can bear enough pressure under the bending moment, to enhance the support carrying capacity, and the thickness of side plate section is less than the thickness of eaves beam section, reduces material cost and structure deadweight, and the hoisting operation is convenient, solves the technical problem that the edge structure of the existing channel shape component cannot satisfy the lightness of deadweight of eaves beam and the integrity structure requirement of beam simultaneously.
