Technical Field
[0001] This utility model relates to a modular steel structure component that is easy to assemble, and belongs to the field of modular steel structure technology. Background Technology
[0002] Modular steel structure buildings are steel structure buildings that are assembled on-site, either wholly or partially, from modular units. The basic unit of a modular steel structure building is a standardized, prefabricated, assembled spatial building module that integrates architectural, structural, electromechanical, and interior functions. Most of the work is completed in the factory, and it meets the requirements for transportation, hoisting, testing, and maintenance. Modular steel structure assembly involves welding and installing components without interlocking joints, making the docking procedures during hoisting cumbersome. Utility Model Content
[0003] The purpose of this invention is to provide a modular steel structure component that is easy to assemble, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a modular steel structure component that is easy to assemble, including a bottom longitudinal beam, a bottom docking base, an upper longitudinal beam, an upper docking base, a vertical pole, and a welded crossbeam. The bottom docking base is positioned and welded at both ends of the bottom longitudinal beam, and the upper docking base is positioned and welded at both ends of the upper longitudinal beam. The bottom docking base is positioned and welded to the upper docking base through the vertical pole. The bottom longitudinal beam and the upper longitudinal beam are each horizontally welded with a welded crossbeam.
[0005] Preferably, the upper longitudinal beam is horizontally welded and installed with structural reinforcing rods.
[0006] Preferably, a concave mating frustum is welded to the top of the upright, and a mating through hole is machined at the center of the bottom of the concave mating frustum. A rectangular mating plug is positioned and welded to the bottom of the upright.
[0007] Preferably, the upper docking base consists of a positioning welding plate and a spherical docking rod, with the spherical docking rod vertically positioned and welded at the center of the positioning welding plate.
[0008] Preferably, the bottom docking base consists of a rectangular tube, mounting bolts, a cross-shaped structural reinforcement frame, and mounting through holes. The mounting through holes machined at the upper end of the rectangular tube are positioned and docked with the mounting bolts for installation. The cross-shaped structural reinforcement frame is installed inside the rectangular tube by positioning welding.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] A rectangular butt plug is welded to the bottom of the upright. The bottom butt base consists of a rectangular tube, mounting bolts, a cross-shaped reinforcing frame, and mounting through holes. The rectangular butt plug at the bottom of the upright is inserted into the rectangular tube of the bottom butt base. The cross-shaped reinforcing frame ensures structural strength, and the mounting bolts position and fix the upright in place.
[0011] The top of the pole is welded with a concave docking frustum. The bottom center of the concave docking frustum is machined with a docking through hole. The crane lifts the upper longitudinal beam and the spherical docking rod of the docking base slides into the docking through hole along the concave docking frustum. During the docking process, the spherical docking rod only needs to move to the concave docking frustum to complete the sliding precise hole docking. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] like Figures 1-5 As shown, a modular steel structure component that is easy to assemble includes a bottom longitudinal beam 1, a bottom docking base 2, an upper longitudinal beam 3, an upper docking base 4, a vertical pole 5, and a welded crossbeam 6. The bottom docking base 2 is positioned and welded at both ends of the bottom longitudinal beam 1, and the upper docking base 4 is positioned and welded at both ends of the upper longitudinal beam 3. The bottom docking base 2 is positioned and welded to the upper docking base 4 through the vertical pole 5. The bottom longitudinal beam 1 and the upper longitudinal beam 3 are respectively horizontally welded with welded crossbeams 6.
[0020] The upper longitudinal beam 3 is horizontally welded with a structural reinforcing rod 7, which serves to strengthen the structure of the upper longitudinal beam 3.
[0021] The top of the upright 5 is welded with a concave docking frustum 9, and the bottom center of the concave docking frustum 9 is machined with a docking through hole 10. A rectangular docking plug 8 is positioned and welded to the bottom of the upright 5. The rectangular docking plug 8 is inserted into the rectangular tube 13 of the bottom docking base for installation.
[0022] The upper docking base 4 consists of a positioning welding plate 11 and a spherical docking rod 12. The spherical docking rod 12 is vertically positioned and welded at the center of the positioning welding plate 11. When the crane lifts the upper longitudinal beam 3, the spherical docking rod 12 of the docking base 4 slides into the docking through hole 10 along the inner groove of the concave docking frustum 9. During the docking process, the spherical docking rod 12 only needs to move to the inner groove of the concave docking frustum 9 to complete the sliding precise hole docking.
[0023] The bottom docking base 2 consists of a rectangular tube 13, mounting bolts 14, a cross-shaped reinforcing frame 15, and a mounting through hole 16. The mounting through hole 16, which is machined at the upper end of the rectangular tube 13, is positioned and docked with the mounting bolts 14 for installation. The cross-shaped reinforcing frame 15 is installed inside the rectangular tube 13 by positioning welding. The cross-shaped reinforcing frame 15 improves the structural strength of the rectangular tube 13 and prevents deformation.
[0024] Specific usage: A modular steel structure component that is easy to assemble. The rectangular docking block at the bottom of the upright is inserted into the rectangular tube of the bottom docking base. The cross-shaped reinforcing frame ensures the structural strength. The mounting bolts position and fix the upright. The crane lifts the upper longitudinal beam and the spherical docking rod of the docking base slides into the docking through hole along the concave docking frustum. During the docking process, the spherical docking rod only needs to move to the concave docking frustum to complete the sliding precise hole docking. It is efficient, stable and safe.
[0025] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
