Technical Field

[0001] The invention relates to the technical field of building metal supporting components, in particular to a building component with a cross-shaped structure and an installation method thereof. Background Art

[0002] Cross-shaped building elements generally refer to columns or beams with a cross-shaped cross section used in building structures. This type of element is called a cross-shaped column or beam in the construction industry, depending on its role in the structure. In the case of a cross-shaped column, its cross section presents a cross shape consisting of four perpendicular intersecting limbs. Cross-shaped building elements are used in buildings where structural efficiency, space utilization, and aesthetic effects are sought.

[0003] For example, a cross-shaped steel column can provide higher load-bearing capacity and better torsion resistance, and is suitable for buildings that bear large loads. Steel column structure refers to a column made of steel used in a building or engineering structure, and it is an important part of a steel structure building. Steel columns are one of the main load-bearing components of a building due to their high load-bearing capacity, good ductility, earthquake resistance, and fast construction speed. They support the weight of the building and possible external loads.

[0004] A cross-shaped steel column structure with Chinese patent application number 201320413484.3 includes a first I-beam beam, a second I-beam beam and a third I-beam beam, the first I-beam beam and the second I-beam beam are assembled and fixed by a first fixing component and a second fixing component, the first I-beam beam and the third I-beam beam are assembled and fixed by a third fixing component and a fourth fixing component, wherein the three first shock-absorbing rubber layers of the first fixing component and the three second shock-absorbing rubber layers of the second fixing component can play a good shock-absorbing and buffering role between the first I-beam beam and the second I-beam beam, the three third shock-absorbing rubber layers of the third fixing component and the three fourth shock-absorbing rubber layers of the fourth fixing component can play a good shock-absorbing and buffering role between the first I-beam beam and the third I-beam beam.

[0005] When existing cross-shaped building components are used to form steel structural columns, it is not convenient to flexibly adjust them according to different building needs and load conditions, which easily leads to the diameter of the steel structural columns being too large or too small, making it difficult to meet the internal space and load-bearing requirements of the building. Summary of the invention

[0006] The technical problem to be solved by the present invention is that the existing cross-shaped building components are not easy to flexibly adjust to meet different building requirements and load conditions when forming steel structure columns, which easily leads to the diameter of the steel structure columns being too large or too small, making it difficult to meet the internal space and load-bearing requirements of the building.

[0015] Preferably, a plurality of triangular teeth are fixedly mounted on the surface of the assembly table, a triangular groove cooperating with the triangular teeth is provided on the inner wall of the adjustment frame, and the triangular groove is movably sleeved on the surface of the triangular teeth to limit the adjustment frame.

[0016] Preferably, a limiting screw is movably connected to the adjustment frame, a second threaded hole is opened on one side of the assembly platform, and the limiting screw extends to the inner cavity of the second threaded hole and is threadedly connected to the inner wall thereof.

[0017] Preferably, the top and the bottom of the regulating frame are both provided with a second connecting platform, and the second connecting platform is provided with a second connecting hole.

[0018] Preferably, a plurality of L-shaped bent plates are fixedly connected to the surface of the bearing mechanism.

[0019] A method for installing a building component with a cross-shaped structure comprises the following steps:

[0020] S1. Use the square tube as the foundation, ensure that the round tube is located in the center, and weld the support plate and the cross-shaped reinforcement frame to reinforce the round tube to enhance the stability of the internal structure of the central support mechanism;

[0021] S2, placing the installation sleeve on the surface of the square tube, and then passing the clamping plate through the clamping slot and welding it to the inner wall of the installation sleeve to achieve preliminary positioning of the installation sleeve;

[0022] S3, installing the assembly platform on the surface of the installation sleeve, using a fixing screw to pass through the through hole and threadedly connect with the first threaded hole of the square tube to fix the assembly platform, so as to fix the bearing mechanism and provide secondary reinforcement for the reinforcement mechanism;

[0023] S4. According to the diameter requirement of the steel structure column, adjust the cooperation between the triangular teeth and the triangular groove to ensure the stability of the position of the adjustment frame. When a large-diameter steel structure column is required to bear a larger load, the triangular groove is sleeved on the outermost triangular tooth surface. When a small-diameter steel structure column is required to increase the internal space of the building, the triangular groove is sleeved on the innermost triangular tooth. When the adjustment of the adjustment frame is completed, the limit screw is passed through the adjustment frame and screwed into the second threaded hole. The limit screw applies pressure to the adjustment frame and the triangular groove, so that the triangular groove is stuck on the surface of the triangular teeth to fix the adjustment frame.

[0024] S5. Select pull pieces of different specifications according to the extension length of the adjustment frame, and then use welding equipment to fix the welding block on the fixed plate to ensure that the pull piece is firmly connected. Then, weld the pull piece to the surface of the adjustment frame to reinforce the adjustment frame for the second time to prevent the adjustment frame from loosening from the surface of the assembly table and ensure that the position and angle of the bearing mechanism are correct.

[0025] S6. After the four bearing mechanisms are installed, a cross structure is formed, so that the building components have no weak axis and have relative stability in all directions, reducing the problems caused by structural asymmetry;

[0026] S7, using the first connection hole on the first connection platform and the second connection hole on the second connection platform, connecting adjacent components by bolts or welding to ensure the integrity of the structure, to form a complete steel structure column, and installing different numbers of building components according to the required length of the steel structure column;

[0027] S8. After the installation is completed, the L-shaped bent plate is welded to the surface of the assembly table to wrap the bearing mechanism, the reinforcement mechanism and the central support mechanism;

[0028] S9. After all assembling is completed, a comprehensive inspection is conducted, including the connection firmness of each component, the verticality and flatness of the structure, and whether it meets the design requirements;

[0029] S10. Perform final tightening and sealing on all connection points to prevent moisture and corrosive substances from entering the structure and affecting its life.

[0030] Beneficial effects of the present invention:

[0031] 1. The present invention can adjust the cooperation between the triangular teeth and the triangular grooves according to the diameter requirements of the steel structure column to ensure the stability of the position of the adjustment frame. When a large-diameter steel structure column is needed to bear a larger load, the triangular groove is sleeved on the outermost triangular tooth surface. When a small-diameter steel structure column is needed to increase the internal space of the building, the triangular groove is sleeved on the innermost triangular tooth. When the adjustment of the adjustment frame is completed, the limit screw is passed through the adjustment frame and screwed into the second threaded hole. The limit screw applies pressure to the adjustment frame and the triangular groove, so that the triangular groove is clamped on the surface of the triangular tooth to fix the adjustment frame. Small-diameter building components The deadweight is lighter, which is especially important for high-rise buildings and long-span structures because they can reduce the burden on the lower structure and foundation. Moreover, inside the building, the small diameter occupies less space, which can create a larger open space and improve space utilization. Large-diameter building components have a larger cross-sectional area and can therefore withstand greater loads, making them suitable for structures that require high bearing capacity. Moreover, the large cross-section provides better structural stability and can resist the influence of lateral forces such as wind loads and earthquakes. Large cross-sections tend to have better ductility, which means that under dynamic loads such as earthquakes, they can absorb more energy and reduce the risk of structural damage.

[0032] 2. The present invention provides a solid central skeleton through the combination of square tubes and round tubes, which enhances the longitudinal stability of the entire component and ensures the strength and rigidity of the structure when subjected to vertical and horizontal loads. The support plate and the cross-shaped reinforcement frame further enhance the bearing capacity of the central support mechanism, enabling it to effectively disperse and transfer the load and support a heavier building structure. The arrangement of the cross-shaped reinforcement frame not only increases the bending resistance of the structure, but also improves the torsional resistance.

[0033] 3. The present invention increases the rigidity and stability of the overall structure by using a reinforcing mechanism in coordination with a central supporting mechanism. The use of a fixing plate, a welding block and a pulling member further strengthens the key parts of the structure, ensuring the strength of the structure when subjected to various loads. The cooperation of the welding block and the pulling member ensures a reliable connection between the reinforcing mechanism and the bearing mechanism, which is particularly important when subjected to dynamic loads. The mounting sleeve is inserted into the slot through a clamping plate, further increasing the stability of the connection between the mounting sleeve and the square tube.

[0034] 4. The present invention can evenly distribute and transfer the load from the upper structure through the coordinated use of the assembly platform and the adjustment frame, ensuring that the entire building components can bear and safely disperse the weight and pressure. The four-way layout of the bearing mechanism and the close integration with the reinforcement mechanism provide all-round support for the building, enhance the overall stability and wind and earthquake resistance of the structure. The bearing mechanism ensures that it can remain stable under various conditions through the coordinated action with the limit screw and the fixing screw, providing a guarantee for the safety of the building.

DETAILED DESCRIPTION

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0048] Embodiment 1, as Figure 1-11 As shown, this embodiment provides a building component with a cross-shaped structure, including a central support mechanism 100, and the central support mechanism 100 includes a square tube 101.

[0049] A circular tube 102 is provided at the center of the inner cavity of the square tube 101, and support plates 104 are fixedly connected to the left and right sides and the front and back sides of the circular tube 102. The side of the support plate 104 away from the circular tube 102 is fixedly connected to the inner wall of the square tube 101, and a cross-shaped reinforcement frame 103 is fixedly connected to the surface of the support plate 104 and the inner wall of the square tube 101.

[0050] Through the combination of square tubes 101 and round tubes 102, a solid central skeleton is provided, which enhances the longitudinal stability of the entire component and ensures the strength and rigidity of the structure when subjected to vertical and horizontal loads. The support plates 104 and the cross-shaped reinforcement frames 103 further enhance the carrying capacity of the central support mechanism 100, enabling it to effectively disperse and transfer loads and support heavier building structures. The arrangement of the cross-shaped reinforcement frames 103 not only increases the bending resistance of the structure, but also improves the torsional resistance.

[0051] It also includes a reinforcing mechanism 200, which is fixedly mounted on the surface of the central supporting mechanism 100. The reinforcing mechanism 200 includes a mounting sleeve 201 mounted on the surface of the square tube 101. The four corners of the surface of the mounting sleeve 201 are fixedly connected to a fixing plate 203. The surface of the fixing plate 203 is fixedly connected to a welding block 205. A pulling piece 206 is fixedly connected to one side of the welding block 205.

[0052] The square tube 101 is provided with slots 105 on both sides, front and back, and a plurality of clamping plates 208 are fixedly connected to the inner wall of the mounting sleeve 201 . The clamping plates 208 penetrate the slots 105 and extend to the inner cavity of the square tube 101 .

[0053] Four corners of the top and bottom of the installation sleeve 201 are provided with first connection platforms 204 , and first connection holes 202 are opened on the first connection platforms 204 .

[0054] By using the reinforcing mechanism 200 and the central supporting mechanism 100 in coordination, the rigidity and stability of the overall structure are increased; the use of the fixing plate 203, the welding block 205 and the pulling member 206 further strengthens the key parts of the structure, ensuring the strength of the structure when subjected to various loads; by using the welding block 205 and the pulling member 206 in coordination, a reliable connection between the reinforcing mechanism 200 and the bearing mechanism 300 is ensured, which is particularly important when subjected to dynamic loads; the mounting sleeve 201 is inserted into the slot 105 through the clamping plate 208, further increasing the stability of the connection between the mounting sleeve 201 and the square tube 101.

[0055] It also includes a supporting mechanism 300, there are four supporting mechanisms 300, and they are installed on the left and right sides and the front and back sides of the reinforcing mechanism 200. The supporting mechanism 300 includes an assembly table 301 arranged on the surface of the installation sleeve 201, and an adjustment frame 304 is movably sleeved on the surface of the assembly table 301. The end of the pulling member 206 away from the welding block 205 is fixedly connected to the surface of the adjustment frame 304.

[0056] A first threaded hole 106 is formed on the surface of the square tube 101 , a through hole 207 is formed on the surface of the mounting sleeve 201 , and a fixing screw 302 is installed on the assembly platform 301 . The fixing screw 302 passes through the through hole 207 and is threadedly connected to the first threaded hole 106 .

[0057] A plurality of triangular teeth 309 are fixedly mounted on the surface of the assembly table 301 , and a triangular groove 307 for use with the triangular teeth 309 is opened on the inner wall of the adjustment frame 304 . The triangular groove 307 is movably sleeved on the surface of the triangular teeth 309 to limit the adjustment frame 304 .

[0058] A limiting screw 303 is movably connected to the adjusting frame 304 , a second threaded hole 308 is opened on one side of the assembly platform 301 , and the limiting screw 303 extends to the inner cavity of the second threaded hole 308 and is threadedly connected to the inner wall thereof.

[0059] A second connection platform 305 is provided at the top and the bottom of the adjustment frame 304 , and a second connection hole 306 is opened on the second connection platform 305 .

[0060] According to the diameter requirement of the steel structure column, the cooperation between the triangular teeth 309 and the triangular grooves 307 is adjusted to ensure the stability of the position of the adjustment frame 304. When a large-diameter steel structure column is needed to bear a larger load, the triangular grooves 307 are sleeved on the surface of the outermost triangular teeth 309. When a small-diameter steel structure column is needed to increase the internal space of the building, the triangular grooves 307 are sleeved on the innermost triangular teeth 309. When the adjustment of the adjustment frame 304 is completed, the limiting screw 303 is passed through the adjustment frame 304 and screwed into the second threaded hole 308. The limiting screw 303 applies pressure to the adjustment frame 304 and the triangular grooves 307, so that the triangular grooves 307 are stuck on the surface of the triangular teeth 309. To fix the adjustment frame 304, small-diameter building components have a lighter deadweight, which is especially important for high-rise buildings and long-span structures because they can reduce the burden on the lower structure and foundation, and inside the building, the small diameter occupies less space, which can create a larger open space and improve space utilization. Large-diameter building components have a larger cross-sectional area and can therefore withstand greater loads, making them suitable for structures that require high bearing capacity. In addition, the large cross-section provides better structural stability and can resist the effects of lateral forces such as wind loads and earthquakes. Large cross-sections tend to have better ductility, which means that under dynamic loads such as earthquakes, they can absorb more energy and reduce the risk of structural damage.

[0061] By using the assembly platform 301 and the adjustment frame 304 in coordination, the load from the upper structure can be evenly distributed and transmitted, ensuring that the entire building components can withstand and safely disperse the weight and pressure. The four-way layout of the bearing mechanism 300 and its close integration with the reinforcement mechanism 200 provide all-round support for the building, enhancing the overall stability and wind and earthquake resistance of the structure. The bearing mechanism 300 works in coordination with the limit screw 303 and the fixing screw 302 to ensure that it can remain stable under various conditions, thus providing a guarantee for the safety of the building.

[0062] A plurality of L-shaped bent plates 400 are fixedly connected to the surface of the supporting mechanism 300 .

[0063] The L-shaped bent plate 400 can tightly connect the bearing mechanism 300, the reinforcing mechanism 200 and the central supporting mechanism 100 to form a more solid and unified whole, thereby improving the rigidity and stability of the structure. The L-shaped bent plate 400 can effectively resist bending and twisting forces due to its shape. When applied to building components, it can enhance its ability to resist lateral forces, such as wind and earthquake forces. The L-shaped bent plate 400 provides additional support at the corners and intersections of the structure, helps to disperse and transfer loads, reduces local stress concentration, and improves the bearing capacity of the overall structure. The installation of the L-shaped bent plate 400 can improve the appearance of the building components, making their surface more flat and smooth. The wrapping effect of the L-shaped bent plate 400 can protect the internal structure from external impact or corrosion, thereby extending the service life of the components.

[0066] S2, sleeve the installation sleeve 201 on the surface of the square tube 101, then pass the clamping plate 208 through the clamping slot 105 and weld it to the inner wall of the installation sleeve 201 to achieve preliminary positioning of the installation sleeve 201;

[0068] S4. According to the diameter requirement of the steel structure column, the cooperation between the triangular teeth 309 and the triangular grooves 307 is adjusted to ensure the stability of the position of the adjustment frame 304.

When a small-diameter steel structure column is required to increase the internal space of the building, the triangular grooves 307 are sleeved on the innermost triangular teeth 309. When the adjustment of the adjustment frame 304 is completed, the limiting screw 303 is passed through the adjustment frame 304 and screwed into the second threaded hole 308. The limiting screw 303 applies pressure to the adjustment frame 304 and the triangular grooves 307, so that the triangular grooves 307 are stuck on the surface of the triangular teeth 309 to fix the adjustment frame 304.

[0069] S5. Select pull pieces 206 of different specifications according to the extension length of the adjustment frame 304, and then use welding equipment to fix the welding block 205 on the fixing plate 203 to ensure that the pull piece 206 is firmly connected. Then, weld the pull piece 206 to the surface of the adjustment frame 304 to perform secondary reinforcement on the adjustment frame 304 to prevent the adjustment frame 304 from loosening from the surface of the assembly table 301, and ensure that the position and angle of the bearing mechanism 300 are correct.

[0070] S6. After the four bearing mechanisms 300 are installed, a cross structure is formed, so that the building components have no weak axis and have relative stability in all directions, thus reducing the problems caused by structural asymmetry;

Using the square tube (101) as a foundation, ensuring that the round tube (102) is located at the center, and welding a support plate (104) and a cross-shaped reinforcement frame (103) to reinforce the round tube (102) to enhance the stability of the internal structure of the central support mechanism (100); S2, sleeve the installation sleeve (201) onto the surface of the square tube (101), then insert the clamping plate (208) through the clamping groove (105) and weld it to the inner wall of the installation sleeve (201), so as to achieve preliminary positioning of the installation sleeve (201); S3, installing the assembly platform (301) on the surface of the installation sleeve (201), using a fixing screw (302) to pass through the through hole (207) and threadedly connect with the first threaded hole (106) of the square tube (101), so as to fix the assembly platform (301), fix the bearing mechanism (300) and perform secondary reinforcement on the reinforcement mechanism (200); S4. According to the diameter requirement of the steel structure column, the cooperation between the triangular clamping teeth (309) and the triangular groove (307) is adjusted to ensure the stability of the position of the adjustment frame (304). When a steel structure column with a large diameter is required to bear a larger load, the triangular groove (307) is sleeved on the surface of the outermost triangular clamping teeth (309). When a steel structure column with a small diameter is required to increase the internal space of the building, the triangular groove (307) is sleeved on the innermost triangular clamping teeth (309). After the adjustment of the adjustment frame (304) is completed, the limiting screw (303) is passed through the adjustment frame (304) and screwed into the second threaded hole (308). The limiting screw (303) applies pressure to the adjustment frame (304) and the triangular groove (307), so that the triangular groove (307) is clamped on the surface of the triangular clamping teeth (309) to fix the adjustment frame (304). S5. Select pulling pieces (206) of different specifications according to the extension length of the adjusting frame (304), and then use a welding device to fix the welding block (205) on the fixing plate (203) to ensure that the pulling piece (206) is firmly connected. Then, the pulling piece (206) is welded to the surface of the adjusting frame (304) to perform secondary reinforcement on the adjusting frame (304) to prevent the adjusting frame (304) from loosening from the surface of the assembly table (301), thereby ensuring that the position and angle of the bearing mechanism (300) are correct. S6. After the four bearing mechanisms (300) are installed, a cross structure is formed, so that the building components have no weak axis and have relative stability in all directions, thereby reducing problems caused by structural asymmetry; S7, using the first connection hole (202) on the first connection platform (204) and the second connection hole (306) on the second connection platform (305), connecting adjacent components by bolts or welding to ensure the integrity of the structure, thereby forming a complete steel structure column, and installing different numbers of building components according to the required length of the steel structure column; S8. After the installation is completed, the L-shaped bent plate (400) is welded to the surface of the assembly platform (301) to wrap the bearing mechanism (300), the reinforcement mechanism (200) and the central support mechanism (100); S9. After all assembling is completed, a comprehensive inspection is conducted, including the connection firmness of each component, the verticality and flatness of the structure, and whether it meets the design requirements; S10. Perform final tightening and sealing on all connection points to prevent moisture and corrosive substances from entering the structure and affecting its life.
