Description

Technical Field

[0001] The utility model relates to the field of truss node design, in particular to a staggered splicing node structure of a C-shaped double-spliced ​​structural member. Background Art

[0002] With the popularization of zinc-aluminum-magnesium high-strength anti-corrosion coatings, more and more photovoltaic engineering applications have chosen zinc-aluminum-magnesium coated steel; this material has 30 years of anti-corrosion ability and the unique quality of self-healing and anti-scratch damage, making it the preferred anti-corrosion steel in humid environments; since welding will damage the zinc-aluminum-magnesium coating, the prior art (announcement number: CN220620718U, announcement date: 2024.03.19) discloses a double-jointed C-type composite column for assembled photovoltaic sheds, which completes the assembly of the component body by docking and assembling two thin-walled steel components, and installs the main beam between the column ears of the two thin-walled steel components to complete the locking. No welding operation is required, which avoids the various disadvantages brought about by the welding process in the prior art, will not damage the surface structure, ensures anti-corrosion ability, and is suitable for relatively humid environments.

[0003] In the above solution, C-type double columns are used in shed-type photovoltaic brackets. With its efficient production process, flexible and convenient installation method, and anti-corrosion performance without welding throughout the whole process, it is very popular in the market and has promoted the prefabricated application of shed-type BIPV power stations. The rich photovoltaic application scenarios also require bracket products to be able to achieve modular and flexible assembly.

[0004] The modular assembly BIPV system allows a limited number of standard beam-column components to be applied to various scenarios with space requirements. To achieve this goal, many places need to realize beam splicing or even column splicing. For example, if the modular components can be transported to the roof of a high-rise building using a freight elevator and then spliced, it will greatly improve efficiency and reduce construction costs. Another example is that if the large-span truss beam-column component system can be assembled on site, the economic benefits of the transportation link will be significant. However, as we all know, columns are the most important components of the structural system. Designers often have great safety concerns about column splicing, and beam splicing should also be selected as much as possible at the location where the bending moment is close to zero, which leads to the contradiction between modular splicing and strength safety of structural components.

[0005] Therefore, it is necessary to design a new staggered splicing node structure of C-type double-jointed structural members to solve the above problems under the premise of ensuring the splicing strength. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The utility model can be applied not only to the splicing between beams, but also to the rigid support connection, as well as to the splicing of columns and the assembly of large-span trusses. The utility model can realize the large-scale pre-production and storage logistics management of the parts of the module assembly BIPV bracket, and can also overcome the vertical transportation problem of high-rise roof BIPV installation; it can greatly reduce the number of assembled structural parts, further increase the applicable space of standard parts, and further promote the large-scale development of module assembly BIPV technology; the utility model can also be applied to the BIPV and BAPV fields of industrial and commercial roofs, providing a simple, flexible, economical and efficient bracket solution; it can also be applied to other non-photovoltaic panel trellis structures.

[0050] like Figure 1-7 As shown, the staggered splicing node structure of the C-shaped double-jointed structural member of the utility model includes a component body 1 and a plurality of through bolts 2; the component body 1 includes a plurality of front C-shaped steels 11 and a plurality of rear C-shaped steels 12, and the front and rear ends of the through bolts 2 respectively pass through the front C-shaped steels 11 and the rear C-shaped steels 12 to complete the locking; a front splicing seam 3 is formed between two adjacent front C-shaped steels 11, and a rear splicing seam 4 is formed between two adjacent rear C-shaped steels 12, and the front splicing seam 3 and the rear splicing seam 4 are staggered with each other; a front inner sleeve 5 is sleeved and fixedly installed in two adjacent front C-shaped steels 11, and a rear inner sleeve 6 is sleeved and fixedly installed in two adjacent rear C-shaped steels 12;

[0051] The principle is: utilize the front splicing seam 3 and the rear splicing seam 4 that are staggered front and back to assemble the component body 1. The staggered splicing seams can make each node on the component body 1 achieve the technical effect of being separated but not separated, realize the purpose of stable splicing, and ensure the overall continuity of the component body 1 structural parts at the same time.

[0052] Furthermore, the middle portion of the through bolt 2 is arranged to pass through the front inner sleeve 5 or the rear inner sleeve 6; thus, the assembly strength of the entire component body 1 can be ensured and the service life is increased.

[0053] Furthermore, a front inner sleeve bolt 7 is fixedly installed between the front inner sleeve 5 and the two adjacent front C-shaped steels 11, and a rear inner sleeve bolt 8 is fixedly installed between the rear inner sleeve 6 and the two adjacent rear C-shaped steels 12; the inner sleeve bolts can be used to install and fix the inner sleeve, thereby improving the overall strength of the component body 1.

[0054] Furthermore: the front C-shaped steel 11 and the rear C-shaped steel 12 are bent into a C-shaped structure, and the edges on both sides of the front C-shaped steel 11 and the rear C-shaped steel 12 are bent to form inward-turned flanges 9, and the inward-turned flanges 9 of the front C-shaped steel 11 and the rear C-shaped steel 12 are arranged to abut against each other, so that the stability of the component body 1 after assembly is higher.

[0055] like Figure 8 As shown, optionally: the cross-section of the front inner sleeve 5 adopts a C-shaped structure, and the C-shaped structure of the front inner sleeve 5 covers the inner side of the front C-shaped steel 11; the cross-section of the rear inner sleeve 6 adopts a C-shaped structure, and the C-shaped structure of the rear inner sleeve 6 covers the inner side of the rear C-shaped steel 12; the inner sleeve can be installed by thickening and extending the C-shaped steel, and then installed and locked with bolts, which can ensure the stable splicing between the two adjacent C-shaped steels.

[0056] like Fig. 9 As shown, optionally: the cross-section of the front inner sleeve 5 adopts a C-shaped structure, and the front inner sleeve 5 and the front C-shaped steel 11 form a U-shaped structure; the cross-section of the rear inner sleeve 6 adopts a C-shaped structure, and the rear inner sleeve 6 and the rear C-shaped steel 12 form a U-shaped structure; this installation method can make the opening of the C-shaped steel closed, and the strength can be effectively improved.

[0057] like Fig.10 As shown, optionally: the front inner sleeve 5 and the rear inner sleeve 6 are both made of rectangular square tubes; the rectangular square tubes can be used as inner sleeves for splicing and assembly to ensure their assembly strength.

[0061] During the splicing and assembly, when the C-shaped steel on one side is spliced, since the front splicing seam 3 and the rear splicing seam 4 are staggered, the other side can remain intact when the C-shaped steel on one side is spliced, so that the double-spliced ​​components at the splicing point are not completely disconnected, and the continuity of the component body 1 can still be maintained; the disconnected part is locked and reinforced with an inner sleeve and bolts. The inner sleeve can be made of a rectangular square tube or C-shaped steel. The inner sleeve connection method can increase the bending resistance of the splicing point, and the bolts can increase the shear and tensile resistance of the splicing point.

[0062] When one section of the front C-shaped steel 11 or the rear C-shaped steel 12 in the component body 1 is disconnected, it can be connected and assembled into a whole through the front inner sleeve bolts 7, the rear inner sleeve bolts 8, the through bolts 2 and the front inner sleeve 5 and the rear inner sleeve 6. After the front C-shaped steel 11 or the rear C-shaped steel 12 is spliced, it is assembled using the through bolts 2 to further strengthen the splicing point and achieve complete and continuous structural reinforcement.

[0063] like Figure 11-22 As shown, the utility model also provides specific installation positions of bolts in 12 implementation cases, which can ensure stable assembly while facilitating on-site assembly of bolts, thereby accelerating the assembly efficiency of photovoltaic brackets. In addition to the above 12 implementation cases, the utility model can also install bolts to other positions, among which it can be determined that: the through bolts 2 pass through the front C-shaped steel 11, the rear C-shaped steel 12, the front inner sleeve 5 and the rear inner sleeve 6 to complete the locking, the front inner sleeve bolt 7 passes through the front C-shaped steel 11 and the front inner sleeve 5 to complete the locking, and the rear inner sleeve bolt 8 passes through the rear C-shaped steel 12 and the rear inner sleeve 6 to complete the locking.
