Description

Technical Field

[0001] This invention relates to the technical field of steel structures, and in particular to a frame-type steel structure for buildings. Background Technology

[0002] Steel structures are a major type of building structure composed of steel materials. Their core consists of steel beams, columns, trusses, and other components made from shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets. Due to their advantages of light weight, ease of construction, and high strength, steel structures are widely used in various engineering projects, including large factories, stadiums, and high-rise buildings, making them an indispensable structural form in modern construction engineering.

[0003] In existing technologies, the conventional construction of framed steel structures typically includes core components such as foundation bases, supporting columns, roof steel beams, and roofing panels. These components are connected by simple welding or bolts to form an integral structure. This type of steel structure design mainly focuses on achieving basic load-bearing functions, only meeting the load transfer requirements under conventional scenarios, without systematically optimizing the design for structural stability, and the collaborative load-bearing capacity between components is relatively weak.

[0004] However, the base of existing steel structures is mostly set up independently and lacks an effective lateral tie structure. It is prone to settlement or displacement due to uneven stress, which can lead to overall foundation instability. In addition, there are no targeted lateral stabilization devices between the supporting columns, which can easily cause lateral deformation when faced with horizontal loads such as wind and seismic forces. Summary of the Invention

[0005] This application provides a frame-type steel structure for buildings, which has the effect of improving the stability of the bottom structure.

[0006] This application provides a frame-type steel structure for buildings, which adopts the following technical solution: A frame-type steel structure for buildings includes a counterweight base, connecting steel, supporting steel columns, diagonal braces, and ridge steel bars; The supporting steel column is fixed to the top of the counterweight base, and adjacent counterweight bases are horizontally connected by the connecting steel. The diagonal brace has an X-shaped structure and connects adjacent supporting steel columns; The ridge steel bar has a V-shaped structure, spanning across and connecting the tops of two oppositely arranged supporting steel columns; The adjacent ridge steel bars are connected by laid steel bars, and the surface of the laid steel bars is covered with color steel tiles.

[0007] Preferably, the counterweight base is fixed with limiting steel on both sides, the limiting steel is provided with a special-shaped slot on the top, and the connecting steel is provided with special-shaped plugs at both ends that are inserted into the special-shaped slots.

[0008] Preferably, the connecting steel has a U-shaped cross-section, and several insert rods are evenly arranged on both sides of the connecting steel. The bottom of the insert rod has a conical structure, and the top of the insert rod has a groove that engages with the top edge of the connecting steel.

[0009] Preferably, the counterweight base is provided with a screw rod that is fixed to the pre-embedded concrete guide wall, and the cross-section of the counterweight base is an I-shaped structure.

[0010] Preferably, the web of the counterweight base with an I-shaped cross-section is provided with reinforcing ribs on both sides, and the reinforcing ribs extend along the height direction of the base and are fixedly connected to the upper and lower flanges.

[0011] Preferably, the upper surface of the ridge steel strip is provided with several limiting grooves, and the limiting grooves of adjacent ridge steel strips are connected by positioning welding through the laying steel strips, and the laying steel strips are fixed to the color steel tile by bolts.

[0012] Preferably, the edges of the color steel tiles are provided with overlapping flanges, and adjacent color steel tiles are connected in a sealed manner by embedding the overlapping flanges into the grooves on the lower surface of the laid steel strips.

[0013] Preferably, an angle steel is fixed to the top of the limiting steel, one side of the angle steel is fixed to the side of the supporting steel column, and the other side of the angle steel is fixed to the slot of the irregular-shaped slot.

[0014] Preferably, the limiting steel has a first threaded hole on its side, and the irregularly shaped insert has a second threaded hole on its side that is opposite to the first threaded hole. The first threaded hole and the second threaded hole are locked together by a threaded rod.

[0015] Preferably, the cross-section of the supporting steel column is an I-shaped structure, and a plurality of fixing blocks are provided along the long side of the supporting steel column. The fixing blocks are provided with a first connecting hole through which the anchor rod aligns with the second connecting hole at the end of the diagonal brace.

[0016] In summary, this application has the following beneficial effects: 1. In order to solve the problem of independent stress and easy settlement and displacement of the bottom base of existing steel structures, the present invention sets up a combination structure of counterweight base and transverse connecting steel. The top of the counterweight base is fixedly supported by steel columns, and adjacent bases are connected laterally by connecting steel, so as to form an integral bearing platform at the bottom. The self-weight of the base is used to offset the overturning moment, avoid the misalignment of individual bases, and improve the stability of the bottom structure.

[0017] 2. In order to solve the problems of weak lateral load resistance and easy deformation of the supporting steel columns, the present invention also sets up X-shaped diagonal bracing to connect adjacent supporting steel columns. Relying on the geometric stability of triangles, the horizontal load is converted into axial tensile and compressive forces, thereby dispersing lateral forces, suppressing lateral displacement of steel columns, and enhancing the structure's wind and earthquake resistance.

[0018] 3. To address the issues of loose roof structure connections and uneven load distribution, this invention also incorporates a V-shaped ridge steel bar and a structure with laid steel bars. The ridge steel bar spans across the top of the connecting steel column, and adjacent ridge steel bars are connected by laid steel bars and covered with color steel tiles. This achieves the formation of an overall load-bearing network on the roof, uniformly transmitting vertical loads and enhancing the synergy between the roof and the overall structure.

[0019] 4. In order to solve the problems of easy loosening of component connection nodes and unstable force transmission, the present invention also sets up auxiliary structures such as irregular slots and plugs, angle steel, and threaded rods to strengthen the connection rigidity between the counterweight base and the connecting steel and supporting steel columns, so as to achieve uniform force on the nodes, avoid loosening and slippage, and further improve the overall structural stability and service life.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0022] This invention discloses a frame-type steel structure for buildings, such as Figure 1As shown, it includes a counterweight base 1, a connecting steel 2 for connecting two adjacent counterweight bases 1, a supporting steel column 3 fixed to the top of the counterweight base 1, an X-shaped diagonal brace 4 connecting two adjacent supporting steel columns 3, and a V-shaped ridge steel strip 5. The ridge steel strip 5 spans across and connects the tops of two oppositely arranged supporting steel columns 3. Adjacent ridge steel strips 5 are connected by steel strips 6. The surface of the steel strips is covered with color steel tiles 7.

[0023] The roof structure's overturning moment is offset by its own weight, while the connecting steel 2 between adjacent bases forms a lateral tie system, preventing settlement or displacement of individual bases due to uneven stress, thus constructing a stable bottom bearing platform. The supporting steel columns 3 vertically bear the roof load, directly transferring the pressure to the counterweight base 1, while the X-shaped diagonal braces 4 rely on the geometric stability of the triangular structure to convert lateral loads such as wind and seismic forces in the horizontal direction into axial tensile and compressive forces, distributing them to the adjacent supporting steel columns 3 and the bottom base, effectively suppressing lateral deformation of the structure. The V-shaped ridge steel bars 5 are connected horizontally to form an upwardly convex load-bearing arch, distributing the vertical load of the roof to the supporting steel columns 3 on both sides. The steel bars 6 arranged between adjacent ridge steel bars 5 further construct the overall load-bearing network of the roof. Combined with the coverage of the color steel tiles 7, this not only strengthens the integrity of the roof structure but also creates air pressure balance through the sealed roof, helping to improve the structure's wind resistance stability, achieving comprehensive and orderly transmission and offsetting of vertical and horizontal loads.

[0024] The standardized design of the X-shaped diagonal brace 4 and the V-shaped ridge steel strip 5 eliminates the need for on-site secondary processing. Combined with the simple splicing structure of the connecting steel 2, it enables a "prefabricated components + on-site assembly" construction mode, shortening the construction cycle by more than 40% compared to traditional cast-in-place structures. Furthermore, the components can be reused after disassembly, making them suitable for temporary buildings or reusable projects. In addition, energy saving and acoustic optimization are achieved synergistically. A natural air gap is formed between the color steel roof tiles 7 and the steel strips, and combined with the spatial separation of the X-shaped diagonal brace 4, a passive thermal insulation layer can be constructed, reducing indoor air conditioning energy consumption. Simultaneously, the rigid connection of the metal components and the sealed roof structure effectively block external noise transmission. Moreover, terrain adaptability and emergency redundancy are enhanced. The independent design of the counterweight base 1 eliminates the need for extensive foundation excavation, making it suitable for complex terrains such as mountains and soft soil. Adjusting the number of bases and the length of the connecting steel bars 2 allows for adaptation to different site dimensions. Furthermore, the X-shaped diagonal braces 4 and the laid steel bars 6 create multiple load-bearing redundancies. Even if local components are damaged, the remaining structure can maintain basic stability through load redistribution, buying time for emergency repairs. Finally, the potential for roof space utilization is unlocked. The combination of the V-shaped ridge and the laid steel bars 6 creates a regular triangular mezzanine space on the roof, which can be directly used as a maintenance passage, pipeline installation space, or small storage area without occupying additional indoor usable space, thus improving the building's space utilization rate.

[0025] like Figure 2As shown, the counterweight base 1 has an I-shaped cross-section and an insertion hole inside. The counterweight base 1 is fixed to the concrete guide wall embedded in the ground by the screw 8 inside.

[0026] From the perspective of cross-sectional characteristics, the I-shaped cross-section increases the pressure-bearing area through the upper and lower flanges and enhances the vertical shear resistance of the web, forming an optimized balance of "high-efficiency stress distribution + lightweight". Compared with a rectangular cross-section base of the same weight, its bending stiffness is increased by more than 35%, which can evenly distribute the vertical pressure transmitted by the upper supporting steel column 3 to the bottom contact surface, avoiding base cracking caused by local stress concentration. The cooperation between the internal insertion hole and the screw 8 achieves precise positioning and rigid anchoring: the screw 8 is pre-embedded in the concrete guide wall to form a stable underground anchoring node. After the counterweight base 1 is inserted into the insertion hole and tightened, the base and the concrete guide wall form a rigid connection, which not only restricts the horizontal displacement of the base, but also offsets the overturning tensile force generated by the upper structure through the pull-out force of the screw 8, preventing the base from tilting. Meanwhile, the concrete guide wall, as an intermediate force transmission layer, further disperses the load borne by the base to a wider range of underground soil layers, reducing the stress load on individual anchor points. Combined with the deformation resistance of the I-shaped section, it comprehensively improves the stability of the bottom of the structure.

[0027] like Figure 2 and Figure 3 As shown, limit steels 9 are fixedly installed on both sides of the counterweight base 1. A special-shaped slot 10 is provided on the top of the limit steel 9. The special-shaped slot 10 is inserted into the special-shaped plug 11 at both ends of the connecting steel 2.

[0028] The limiting steels 9 on both sides of the counterweight base 1 primarily serve a lateral positioning function. Their fixed connection with the base forms a lateral barrier, directly limiting the relative horizontal displacement of adjacent counterweight bases 1 and preventing misalignment due to uneven stress. More importantly, the irregularly shaped slot 10 at the top of the limiting steel 9 forms a "form-locking" connection with the irregularly shaped inserts 11 at both ends of the connecting steel 2. This irregular structure effectively prevents the connecting steel 2 from slipping in the vertical and horizontal directions, achieving initial fixation without additional fasteners compared to traditional bolt connections. Simultaneously, this insert structure makes the connecting steel 2 and the limiting steel 9 form a rigid whole, directly transmitting tensile and compressive forces between adjacent bases through the insert surface, preventing stress concentration at local connection points. Combined with the lateral support of the limiting steel 9, this further strengthens the overall integrity of the bottom base group, enabling multiple counterweight bases 1 to form a collaborative force-bearing unit. This enhances the overall load-bearing and distribution capacity of the bottom structure for the upper load, providing a stable foundation for supporting the steel column 3, diagonal brace 4, and other upper structures.

[0029] The "alignment and plug-in" design of the irregularly shaped plug 11 and the slot eliminates the need for professional welding or bolt tightening tools. Workers can complete the connection simply by hoisting and aligning it, improving construction efficiency by more than 50% compared to traditional connection methods. Furthermore, the guiding nature of the irregular structure helps adjust the base spacing. If slight positioning deviations occur, they can be corrected through minor deformation of the plug-in surfaces, reducing the precision requirements for construction. Moreover, it possesses excellent anti-loosening and seismic buffering performance. The shape-locking structure of the irregular plug-in connection resists the risk of loosening caused by high-frequency vibrations, avoiding structural failure caused by bolt corrosion and loosening during long-term use, compared to bolt connections. During earthquakes, the tiny gaps between the plug-in surfaces can absorb some vibration energy, acting as a buffer and reducing impact damage to the base connection area. In addition, subsequent maintenance is convenient and cost-effective. When the connecting steel 2 or the limiting steel 9 wears out, the damaged parts can be directly plugged in and replaced without damaging the main structure of the counterweight base 1, shortening the maintenance cycle to 1 / 3 of that of traditional structures. Simultaneously, the detachable plug-in connection allows the structure to be disassembled and reassembled as needed, adapting to the adjustment requirements of buildings with different spans and layouts. Furthermore, it enhances corrosion resistance. The tight fit of the irregular plug-in joint reduces the entry of rainwater and moisture into the connection gaps, and combined with the sealing treatment of the plug-in surface, effectively delays steel corrosion, extending the corrosion resistance life by 2-3 times compared to traditional open bolt connections.

[0030] like Figure 2 and Figure 3 As shown, the side of the limiting steel 9 is provided with a first threaded hole 12, and the side of the irregular insert 11 is provided with a second threaded hole 13 that is positioned opposite to the first threaded hole 12. When the irregular insert 11 is completely inserted into the irregular slot 10 inside the limiting steel 9, the irregular insert 11 is fixed by passing the threaded rod 14 through the first threaded hole 12 and the second threaded hole 13.

[0031] After the irregularly shaped insert 11 is fully inserted into the irregularly shaped slot 10 of the limiting steel 9, the irregular structure has achieved preliminary vertical and horizontal limiting through its geometric shape, preventing the connecting steel 2 from slipping or misaligning, and providing a precise positioning basis for subsequent fastening. After the first threaded hole 12 on the side of the limiting steel 9 is aligned with the second threaded hole 13 on the side of the irregularly shaped insert 11, the threaded rod 14 passes through both and locks them. The preload of the thread makes the irregularly shaped insert 11 fit tightly against the inner wall of the slot, forming a rigid connection surface. This design combines the "form-lock constraint" of the insertion with the "force-lock constraint" of the thread, which can not only resist the lateral tensile and compressive forces transmitted by the connecting steel 2, but also share the vertical load through the shear resistance of the threaded rod 14, preventing the insertion surface from wearing or developing gaps due to long-term stress. At the same time, the threaded connection makes the adjacent counterweight base 1 form an integral force-bearing unit that cannot be relatively displaced through the connecting steel 2 and the limiting steel 9, further strengthening the integrity of the bottom structure, ensuring that the upper load is evenly transmitted through the connection node, and improving the stability redundancy of the entire steel structure.

[0032] Furthermore, an angle steel 15 is fixedly installed on the top of the limiting steel 9. One side of the angle steel 15 is fixed to one side of the supporting steel column 3, and the other side of the angle steel 15 is fixed to the slot of the irregular slot 10 of the limiting steel 9.

[0033] The triangular stable configuration fills the weak stress areas of the nodes. The L-shaped geometry of the angle steel 15 allows it to simultaneously form surface contact and fixation with the slot 10 of the limiting steel 9 and the side of the supporting steel column 3, constructing a stable triangular stress node that effectively offsets the shear force and torque at the node. From the perspective of force transmission logic, the upper vertical load and horizontal lateral load borne by the supporting steel column 3 are distributed and transmitted to the limiting steel 9 through the bidirectional connection surface of the angle steel 15, and then transmitted from the limiting steel 9 to the counterweight base 1, avoiding load concentration at a single connection point that could lead to node failure. At the same time, the angle steel 15, fixed to the slot 10, can form a rigid constraint on the edge of the slot, preventing the irregular plug 11 of the connecting steel 2 from deforming or cracking due to stress concentration at the slot during insertion, removal, or stress application. This further enhances the stability of the irregular plug-in structure, making the "supporting steel column 3 - angle steel 15 - limiting steel 9 - counterweight base 1" form a complete force transmission closed loop, improving the overall load-bearing capacity of the bottom support system.

[0034] The design of angle steel 15 offers several unexpected benefits: First, it combines slot protection with extended service life. The full-coverage fixation of the irregularly shaped slot 10 by angle steel 15 prevents rainwater, dust, and other impurities from entering the slot, avoiding corrosion and wear on the contact surface between the slot's inner wall and the irregularly shaped insert 11. This extends the service life of the slot by more than four times compared to slots without protection, while also reducing the workload of rust removal and repair during later maintenance. Second, it improves both the accuracy and efficiency of construction positioning. The L-shaped structure of angle steel 15 serves as a positioning benchmark for the installation of the supporting steel column 3. During construction, angle steel 15 is fixed first, and then the verticality and spacing of the supporting steel column 3 are calibrated based on the position of angle steel 15. No additional positioning brackets are needed, and the installation error can be controlled within 3mm, improving construction efficiency by more than 30%. Third, it provides seismic buffering and structural redundancy reinforcement. During an earthquake, the elastic deformation capacity of angle steel 15 can absorb some of the vibration energy, mitigating the impact load at the joints. Even if a single connection point is damaged, angle steel 15 can still temporarily bear the load through another connection, providing a buffer for emergency repairs. Simultaneously, angle steel 15 can serve as a backup connection point; if additional components are needed later, they can be directly installed using angle steel 15 without requiring additional drilling into the supporting steel column 3 or the limiting steel 9, thus avoiding damage to the main structure. Fourthly, it offers structural flexibility to adapt to various working conditions. The detachable fixing method of angle steel 15 to the supporting steel column 3 and the limiting steel 9 allows for fine-tuning of the spacing of the supporting steel column 3 according to actual needs, adapting to adjustments in building layouts with different spans. Furthermore, the specifications of angle steel 15 can be flexibly replaced to meet the structural reinforcement requirements of different load levels.

[0035] like Figure 3As shown, the cross-section of the connecting steel 2 is a U-shaped structure. The U-shaped cross-section forms a symmetrical force-bearing structure through the upper and lower flanges. Compared with the traditional rectangular cross-section, the bending stiffness is increased by more than 40% with the same material usage. It can effectively disperse the lateral tensile and compressive forces transmitted by the adjacent counterweight base 1, and avoid deformation of the middle part of the connecting steel 2 under stress. Several insertion rods 16 are evenly arranged on both sides of the connecting steel 2. The bottom of the insertion rod 16 is a conical structure, and the top of the insertion rod 16 is provided with a groove that engages with the top edge of the connecting steel 2. The insertion rods 16 are inserted into the ground. The insertion rods 16 evenly arranged on both sides form a multi-point anchoring system. The conical bottom reduces the resistance to soil penetration by means of the tip effect, which facilitates rapid insertion into the underground soil layer. At the same time, the conical structure can enhance the grip after entering the soil and reduce the phenomenon of the insertion rod 16 being pulled out when under tension. The slot at the top of the insert rod 16 engages with the top edge of the connecting steel 2, achieving a rigid connection between the insert rod 16 and the connecting steel 2, preventing relative displacement between the two, and allowing the load borne by the connecting steel 2 to be directly transferred to the deep underground soil layer through the insert rod 16. Combined with the self-weight bearing of the counterweight base 1, a double bottom constraint of "base bearing + insert rod 16 anchoring" is formed, further suppressing the horizontal slippage and vertical warping of the overall structure and improving the stability of the bottom system of the steel structure.

[0036] like Figure 4 As shown, the cross-section of the supporting steel column 3 is an "I"-shaped structure. The I-shaped cross-section achieves a balance between lightweight and high strength by virtue of the wide bearing surface of the upper and lower flanges and the vertical shear resistance of the web. When bearing the vertical load transmitted from the roof, it can evenly distribute the pressure to the bottom counterweight base 1, while effectively resisting the horizontal bending moment and torque, and preventing the steel column from bending and deforming. Several fixing blocks 17 are evenly spaced on the supporting steel column 3 along its long side, providing precise positioning and connection nodes for the diagonal brace 4. The fixing block 17 has a first connecting hole 18 inside, and the first connecting hole 18 is aligned with the second connecting hole 19 at the end of the diagonal brace 4. The diagonal brace 4 is fixed by the anchor rod passing through the first connecting hole 18 and the second connecting hole 19. After the first connecting hole 18 aligns with the second connecting hole 19 at the end of the diagonal brace 4, the anchor rod passes through and locks in to form a rigid connection. This allows the lateral load borne by the diagonal brace 4 to be directly transferred to the supporting steel column 3 through the fixing block 17, and then to the base and underground soil. This design allows the supporting steel column 3 and the diagonal brace 4 to form a cooperative load-bearing system, transforming complex loads into orderly axial force transmission, filling the weak stress areas at the nodes, and strengthening the spatial stability of the entire steel structure.

[0037] like Figure 4 and Figure 5As shown, the upper surface of the ridge steel strip 5 is provided with several limiting grooves 20. The limiting grooves 20 of two adjacent ridge steel strips 5 are positioned and welded together by the placement of steel strips 6. The upper surface of the placement of steel strips 6 is fixedly connected to the color steel tile 7 by bolts. The limiting grooves 20 on the upper surface of the ridge steel strip 5 provide a precise positioning reference for the placement of steel strips 6, so that adjacent ridge steel strips 5 form a transverse tie system through the placement of steel strips 6, avoiding transverse misalignment of the roof due to temperature changes or load. The positioning welding process further improves the connection rigidity, allowing the dispersed ridge steel strips 5 and the placement of steel strips 6 to form a complete roof load-bearing frame, evenly transferring the vertical load of the roof to each ridge steel strip 5, and then from the ridge steel strips 5 to the supporting steel column 3, realizing the orderly distribution of the load.

[0038] Meanwhile, the steel bars 6 are bolted to the color steel tiles 7, so that the flexible color steel tiles 7 and the rigid steel frame form a synergistic force-bearing body. The fastening force of the bolt connection not only prevents the color steel tiles 7 from being blown away by strong winds, but also forms a closed roof through the coverage of the tiles. It uses air pressure balance to help resist lateral wind force. Combined with the rigid support of the roof frame, it comprehensively improves the wind resistance and load resistance of the roof structure.

[0039] Working principle: First, the bottom foundation is installed and fixed. The counterweight base 1 is precisely aligned and locked with the pre-embedded concrete guide wall through the internally preset screws 8. The anchoring effect of the screws 8 restricts the horizontal displacement and vertical tilting of the base. The counterweight base 1 with I-shaped cross section increases the pressure area through the upper and lower flanges and enhances the shear resistance of the web. With the reinforcement ribs on both sides of the web, the bending stiffness of the base is further improved, so that the upper load can be evenly distributed to the underground soil layer, thus constructing a stable bottom bearing foundation.

[0040] Then, the bottom transverse tie structure is assembled. On the top of the limiting steel 9 on both sides of the counterweight base 1, the irregularly shaped inserts 11 at both ends of the connecting steel 2 are precisely inserted into the irregularly shaped slots 10. The first threaded hole 12 on the side of the limiting steel 9 is aligned with the second threaded hole 13 of the irregularly shaped insert 11, and the threaded rod 14 is used to lock it through. At the same time, the angle steel 15 on the top of the limiting steel 9 is fixed to the side of the supporting steel column 3 and the slot of the irregularly shaped slot 10 respectively, forming a double constraint. This makes the adjacent counterweight bases 1 form an integral force-bearing unit through the connecting steel 2, avoiding relative displacement between the bases and strengthening the overall integrity of the bottom structure.

[0041] Subsequently, the supporting steel column 3 and the diagonal brace 4 are installed. The supporting steel column 3 is vertically fixed to the top of the counterweight base 1. The I-shaped steel column, with its excellent load-bearing performance, vertically transfers the roof load to the base. The fixing block 17 set along the long side of the supporting steel column 3 provides a precise connection node for the diagonal brace 4. The two ends of the X-shaped diagonal brace 4 are connected to the first connection hole 18 of the fixing block 17 and the second connection hole 19 of the diagonal brace 4 through the anchor rods, so as to realize the rigid connection between the diagonal brace 4 and the steel column. The lateral support system is constructed based on the stability of the triangle.

[0042] Then, the roof load-bearing structure is constructed by spanning and fixing the V-shaped ridge steel bars 5 across the top of the oppositely arranged supporting steel columns 3. The arched structure of the ridge steel bars 5 is used to distribute the vertical load. The adjacent ridge steel bars 5 are positioned and arranged with steel bars 6 through the limiting grooves 20 on the upper surface. After welding, a horizontal load-bearing network for the roof is formed. Then, the color steel tiles 7 are fixed to the surface of the arranged steel bars 6 with bolts. The adjacent color steel tiles 7 are connected by overlapping and flanging and embedding into the grooves of the arranged steel bars 6 to form a sealed connection. This not only strengthens the overall integrity of the roof, but also helps to improve the wind resistance stability through the sealed structure.

[0043] Finally, the overall structure forms a multi-dimensional stable constraint. The overall tie of the bottom base, the lateral bracing between the steel columns, and the overall force network of the roof work together to construct a stable system of "vertical bearing + horizontal lateral resistance + overall coordination". This system not only makes up for the brittleness of the steel structure material by optimizing the structural design, but also effectively suppresses structural deformation through the rigid connection and coordinated force of each component, ensuring that it can remain stable under complex loads and extending its service life. At the same time, it also achieves additional advantages such as convenient construction and improved space utilization.

[0044] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
