This technology has the advantages of high efficiency, environmental protection, and energy saving. It is widely used in high-rise buildings, industrial plants, commercial facilities and other fields. Compared with traditional cast-in-place concrete structures, prefabricated building steel structures have higher construction efficiency, lower energy consumption and less waste emissions. At the same time, they can also improve the seismic resistance and durability of buildings. With the continuous advancement and promotion of technology, the application prospects of prefabricated building steel structures are becoming more and more broad.

[0003] After searching, the application number is CN202322157628.X. A kind of building prefabricated steel structure, which relates to the technical field of steel structure, includes an auxiliary mechanism, and the top of the auxiliary mechanism is fixedly installed with a mounting mechanism. In the present invention, the mounting mechanism includes two drag steel plates, the tops of the two drag steel plates are fixedly installed with fixed blocks, the tops of the two fixed blocks are provided with round holes, the inner surfaces of the two round holes are fixedly inserted with rotating shafts, the outer surfaces of the two rotating shafts are movably sleeved with rotating blocks, the outer surfaces of the two rotating shafts are fixedly sleeved with fixing rings, the tops of the inner walls of the two drag steel plates are in contact with a transverse steel plate, the tops of the transverse steel plates are provided with two fixing holes, and the outer surfaces of the two fixing blocks are movably inserted inside the two fixing holes, and the connection between the transverse steel plate and the two drag steel plates is completed by rotating the two rotating blocks. This installation process is simple and the cycle is short, thereby improving the work efficiency of the installation of the prefabricated steel structure.

[0004] Application number CN202321315998.5 discloses an assembled steel structure load-bearing component, including a longitudinal load-bearing beam and a transverse load-bearing beam, wherein the inner side wall of the upper end of the longitudinal load-bearing beam is sleeved with a U-shaped slide member, the outer side of the U-shaped slide member is fixedly connected with a U-shaped supporting groove, the upper and lower ends of the U-shaped slide member away from the U-shaped supporting groove are penetrated and sleeved with a slide bar, the outer top end of the slide bar is fixedly connected with a limit plate, the inner peripheral surface of the limit plate is fixedly connected with a spring, the inner top end of the slide bar away from the limit plate is fixedly connected with a supporting roller component, the middle part of the U-shaped slide member away from the U-shaped supporting groove is threadedly connected with a support screw, and the inner top end of the support screw is rotatably connected with a friction damping disk through a rotating shaft. The present invention can be used to dismantle the transverse load-bearing beam when it is necessary to do so without the need for lifting equipment, and the transverse load-bearing beam can also be dismantled by driving the U-shaped slide member to slowly move downward.

[0005] Although the above-mentioned steel structure is easy to assemble and disassemble, the supporting area of ​​the crossbeam is fixed and cannot be changed. When the support on the top of the steel structure is too heavy, the contact area between the crossbeam and the support is small, and the load-bearing force it receives cannot be dispersed, which easily causes bending and damage to the steel structure. In addition, when assembling the crossbeam, it is generally necessary to place the two ends of the crossbeam on the top of the vertical beam respectively, and then install them with tools such as bolts. However, before the crossbeam and the vertical beam are assembled, manual or mechanical equipment is required to support or suspend the crossbeam to prevent the contact ends of the crossbeam and the vertical beam from shaking and deviating, which affects the assembly. Therefore, the operation is cumbersome, time-consuming and labor-intensive. Summary of the invention

[0037] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0038] like Figures 1 to 6 As shown, this embodiment proposes an assembled composite steel structure, including two symmetrically arranged vertical beams 1 and a horizontal beam 2 arranged between the tops of the two vertical beams 1, a locking component is provided between the vertical beam 1 and the horizontal beam 2, which can limit and fix the horizontal beam 2 when the horizontal beam 2 is erected on the top of the vertical beam 1, the locking component includes a guide component arranged between the vertical beam 1 and the horizontal beam 2 for limiting the horizontal beam 2, a fixing box 4 arranged on the outside of the vertical beam 1 near the top, and a locking component arranged inside the fixing box 4 for fixing the horizontal beam 2 and the vertical beam 1, a bearing component for increasing the contact area between the horizontal beam 2 and the support is provided on the top of the horizontal beam 2, the bearing component includes a support plate 3 detachably arranged on both sides of the top of the horizontal beam 2 and a fixing component arranged at the bottom of the horizontal beam 2, and a support component for dispersing the bearing force of the support plate 3 is also provided at the bottom of the vertical beam 1;

[0039] When the steel structure needs to be installed, the two side ends of a cross beam 2 are first respectively placed between the tops of the two vertical beams 1. When the end of the cross beam 2 contacts the top of the vertical beam 1, the cross beam 2 can be guided and limited by the provided guide component to prevent the cross beam 2 from shaking and deviating from the top of the vertical beam 1 to affect the assembly. When the end of the cross beam 2 completely contacts the top of the vertical beam 1, the cross beam 2 and the vertical beam 1 can be immediately fixed by the provided locking component, which not only saves time and manpower, but also prevents the cross beam 2 from shaking when in contact with the vertical beam 1 to affect the assembly. In addition, when the object supported by the steel structure is too large, Or when it is too heavy, two support plates 3 can be installed on both sides of the top of the beam 2 respectively, and the support plates 3 and the beam 2 can be fixed by fixing parts. At the same time, the entire beam 2 and the bottom of the support plates 3 can be stably supported, which can not only increase the contact area between the beam 2 and the supported object, but also improve the supporting effect on the object; at the same time, through the setting of the support assembly, the pressure on the beam 2 and the support plate 3 can be dispersed into multiple smaller pressures and act on both sides of the bottom plate 12, thereby preventing the beam 2 from bending due to excessive pressure, and further improving the supporting effect of the steel structure.

[0040] Specifically, Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10 , Fig.11 and Fig.12 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the guide component includes a mounting groove 101 opened at the top of the vertical beam 1 and matched with the end of the horizontal beam 2, a plurality of guide grooves 102 opened at the bottom wall of the mounting groove 101, and a plurality of guide posts 9 arranged at the bottom of both sides of the horizontal beam 2;

[0041] The locking component includes a fixing column 5 slidably arranged on the inner wall of the fixing box 4 and a compression spring 501 arranged between the fixing column 5 and the inner bottom wall of the fixing box 4. The side walls of the vertical beam 1 and the horizontal beam 2 are provided with fixing holes 203 that match the fixing column 5.

[0042] When the two side ends of the cross beam 2 are butted against the mounting groove 101 at the top of the vertical beam 1, the guide column 9 at the bottom of the cross beam 2 will first be inserted into the guide groove 102 at the bottom of the mounting groove 101 and continue to slide down. At this time, the cooperation between the guide column 9 and the guide groove 102 can guide and limit the downwardly moved cross beam 2 to prevent the cross beam 2 from being offset due to shaking and unable to accurately butt against the mounting groove 101. When the cross beam 2 enters the mounting groove 101, it will first contact the fixing column 5 and squeeze the fixing column 5 into the fixing box 4 to compress the compression spring 501. When the end of the cross beam 2 is completely in contact with the mounting box 101, the fixing column 5 will be pressed into the fixing box 4 to compress the compression spring 501. After the inner walls of the mounting groove 101 abut against each other, the fixing holes 203 on the side walls of the horizontal beam 2 and the vertical beam 1 will overlap and be flush with the fixing column 5. At this time, the compression spring 501 will be released from the force and drive the fixing column 5 to bounce into the fixing hole 203 to lock and fix the horizontal beam 2 and the vertical beam 1. As a result, the horizontal beam 2 can be self-locked when it is erected on the top of the vertical beam 1, and the erected horizontal beam 2 can also be limited. This not only prevents the horizontal beam 2 from shaking and displacing to affect the installation work, but also does not require workers to use a large number of screws and nuts to lock and assemble the vertical beam 1 and the horizontal beam 2, thereby saving time and manpower.

[0043] In addition, the locking component also includes a bolt 6 threadedly arranged on the side wall of the fixing box 4 and a pull rope arranged between the screw-in end of the bolt 6 located on the inner side of the fixing box 4 and the fixing column 5; when the cross beam 2 and the vertical beam 1 need to be disassembled, the bolt 6 can be rotated toward the outside of the fixing box 4, and the fixing column 5 can be pulled back into the fixing box 4 and disengaged from the fixing hole 203 by the pull rope. At this time, the cross beam 2 is loosened, and the cross beam 2 can be removed from the top of the two vertical beams 1.

[0044] The side wall of the vertical beam 1 is also provided with a buffer reset member, which includes a fixed frame 7 arranged on the outside of the vertical beam 1, a slide plate 8 slidably arranged inside the fixed frame 7, and a buffer spring 701 arranged between the bottom of the slide plate 8 and the inner bottom wall of the fixed frame 7, wherein the side walls at both ends of the cross beam 2 are also provided with convex plates matching with the slide plate 8; when the cross beam 2 is placed to the top of the vertical beam 1, the convex plates on the side walls of the cross beam 2 will contact with the slide plate 8, at this time, the downwardly moving cross beam 2 will squeeze the slide plate 8 to slide toward the inside of the fixed frame 7, and the buffer spring 701 can buffer the downwardly moving cross beam 2. The end of the horizontal beam 2 is prevented from directly colliding with the top of the vertical beam 1 and being damaged. Moreover, if the horizontal beam 2 is manually lifted and placed on the top of the vertical beam 1, the reaction force of the buffer spring 701 can save labor, making it easier for workers to stably set up the horizontal beam 2 on the top of the vertical beam 1 for installation. In addition, when the fixing column 5 is pulled out of the fixing hole 203 by the pull rope, the buffer spring 701 will be released from the force and drive the slide plate 8 to bounce upward, thereby pushing the horizontal beam 2 to move upward and separate from the vertical beam 1, thereby increasing the disassembly speed of the horizontal beam 2.

[0045] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.13 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, both sides of the top of the crossbeam 2 are provided with fixing grooves 201 for installing the support plate 3, the inner wall of the fixing groove 201 is provided with a plurality of limiting holes 202, and the side wall of the support plate 3 is provided with a plurality of limiting columns 301 matched with the limiting holes 202;

[0046] The fixing parts include a reinforcing rib plate 10 with a triangular structure, a plurality of steel bars 1001 arranged on the top of the reinforcing rib plate 10, a positioning plate 1003 arranged on the side wall of the reinforcing rib plate 10, and a plug plate 1002 arranged on the top of the positioning plate 1003. A plurality of steel bars grooves 303 corresponding to the steel bars 1001 are provided in the middle of the bottom of the support plate 3, and a slot 302 matching the plug plate 1002 is provided at the bottom edge of the support plate 3.

[0047] The fixing member also includes a triangular plate 11 disposed on both sides of the bottom of the positioning plate 1003 and a mounting plate 1101 disposed at the end of the triangular plate 11;

[0048] When the support area of ​​the top of the beam 2 needs to be increased, the limiting column 301 of the side wall of the support plate 3 is inserted into the limiting hole 202 on the inner wall of the fixing groove 201 at the top of the beam 2, and the support plate 3 can be inserted on both sides of the top of the beam 2. At this time, the reinforcing rib plate 10 is abutted against the bottom of the beam 2, which not only allows the steel bar column 1001 at the top of the reinforcing rib plate 10 to be inserted into the steel bar groove 303 at the bottom of the support plate 3, but also allows the plug plate 1002 at the top of the positioning plate 1003 to pass through the interior of the beam 2 and be inserted into the slot 302 at the bottom of the support plate 3, and then the positioning plate 1003 is fixed by a plurality of screws. The 003 thread is installed at the bottom of the cross beam 2, so that it can not only fix the support plate 3, but also increase the supporting strength of the cross beam 2 through the reinforcing rib plate 10, to prevent the support plate 3 from being separated from the cross beam 2 due to excessive shear force. At the same time, a number of screws can be used to connect the mounting plate 1101 to the inner wall of the vertical beam 1. Therefore, the reinforcing rib plate 10 and the vertical beam 1 can be connected through the set triangular plate 11, so as to further improve the supporting effect of the cross beam 2 and the vertical beam 1, and the supporting component is also easy to install and disassemble, and thus convenient to transport and carry.

[0049] like Figures 1 to 7 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the support assembly includes a bottom plate 12 arranged at the bottom of the vertical beam 1, a moving seat 13 slidably arranged on both sides of the top of the bottom plate 12, a pressing seat 14 slidably arranged on both sides of the vertical beam 1, a support column 15 movably arranged between the moving seat 13 and the pressing seat 14, and a pressing component arranged between the support plate 3 and the pressing seat 14;

[0050] The extrusion component includes a pressure column 16 detachably mounted between the support plate 3 and the pressure seat 14 and a reinforcing column 17 movably arranged between the pressure column 16 and the bottom of the support plate 3;

[0051] When the steel structure needs to be installed, the pressing seat 14 is moved downward, and the supporting column 15 drives the moving seat 13 to slide toward both sides on the top of the bottom plate 12. A slide groove can be opened on the bottom plate 12, and the moving seat 13 is set inside the slide groove, which can improve the sliding stability of the moving seat 13. After the supporting column 15 drives the moving seat 13 to abut against the edge of the slide groove, the two ends of the pressing column 16 are respectively installed at the top of the pressing seat 14 and the bottom edge of the support plate 3 by screws, and then the hinge seat is installed near the middle of the side wall of the pressing column 16 and the bottom of the support plate 3, and the hinge seat is fixed between the two hinge seats. A reinforcing column 17 is movably installed so that the reinforcing column 17, the pressure column 16 and the support plate 3 form a triangular structure, thereby improving the stability of the support plate 3, and the pressure on the support plate 3 and the cross beam 2 will be dispersed to multiple support columns 15 and the bottom plate 12, so as to avoid the cross beam 2 and the support plate 3 from being bent and damaged due to excessive pressure, and the vertical beam 1 and the bottom plate 12 are also installed together by screws and nuts. Therefore, the vertical beam 1, cross beam 2, load-bearing components and support components in the present application can be installed and disassembled, thereby facilitating the disassembly and transportation of the steel structure.

[0052] The working principle of the present invention is as follows: when the steel structure needs to be installed, the two side ends of a cross beam 2 are first respectively placed between the tops of the two vertical beams 1. When the end of the cross beam 2 contacts the top of the vertical beam 1, the guide column 9 at the bottom of the cross beam 2 will first be inserted into the guide groove 102 at the bottom of the installation groove 101 and continue to slide down, so as to guide and limit the downwardly moved cross beam 2 to prevent the cross beam 2 from being offset due to shaking and unable to accurately abut against the installation groove 101. When the end of the cross beam 2 completely abuts against the inner wall of the installation groove 101, the cross beam 2 is The fixing holes 203 on the side walls of the beam 2 and the vertical beam 1 will overlap and be flush with the fixing column 5. At this time, the compression spring 501 will be released from the force and drive the fixing column 5 to bounce into the fixing hole 203 to lock and fix the horizontal beam 2 and the vertical beam 1. Therefore, when the horizontal beam 2 is erected on the top of the vertical beam 1, the two can be self-locked, and the erected horizontal beam 2 can also be limited. This not only prevents the horizontal beam 2 from shaking and displacing to affect the installation work, but also does not require workers to use a large number of screws and nuts to lock and assemble the vertical beam 1 and the horizontal beam 2, thereby saving time and manpower.

[0053] Moreover, when the cross beam 2 is placed on the top of the vertical beam 1, the convex plate on the side wall of the cross beam 2 will contact the slide plate 8. At this time, the downwardly moving cross beam 2 will squeeze the slide plate 8 to slide toward the inside of the fixed frame 7, and the buffer spring 701 can buffer the downwardly moving cross beam 2 to prevent the end of the cross beam 2 from directly colliding with the top of the vertical beam 1 and being damaged. Moreover, if the cross beam 2 is manually lifted and placed on the top of the vertical beam 1, the reaction force of the buffer spring 701 can also save labor, making it convenient for workers to stably place the cross beam 2 on the top of the vertical beam 1 for installation. In addition, when the fixing column 5 is pulled out of the fixing hole 203 by the pull rope, the buffer spring 701 will also be released from the force to drive the slide plate 8 to bounce upward, thereby pushing the cross beam 2 to move upward and separate from the vertical beam 1, thereby increasing the disassembly speed of the cross beam 2.

[0054] When it is necessary to increase the supporting area of ​​the top of the beam 2, the limiting column 301 of the side wall of the supporting plate 3 can be inserted into the limiting hole 202 on the inner wall of the fixing groove 201 at the top of the beam 2, and the supporting plate 3 can be inserted on both sides of the top of the beam 2. At this time, the reinforcing rib plate 10 is abutted against the bottom of the beam 2, which not only allows the steel bar column 1001 at the top of the reinforcing rib plate 10 to be inserted into the steel bar groove 303 at the bottom of the supporting plate 3, but also allows the plug plate 1002 at the top of the positioning plate 1003 to pass through the interior of the beam 2 and be inserted into the slot 302 at the bottom of the supporting plate 3. Then, the positioning plate 1003 is threadedly installed on the bottom of the beam 2 through a number of screws, which not only fixes the support plate 3, but also improves the supporting strength of the beam 2 through the reinforcing rib plate 10 to prevent the support plate 3 from being separated from the beam 2 due to excessive shear force. At the same time, the mounting plate 1101 can be connected to the inner wall of the vertical beam 1 by a number of screws. Therefore, the reinforcing rib plate 10 and the vertical beam 1 can be connected through the set triangular plate 11, thereby further improving the supporting effect of the beam 2 and the vertical beam 1.

[0055] After the cross beam 2 is installed between the two vertical beams 1, the pressure seat 14 is moved downward, and the moving seat 13 is driven by the support column 15 to slide toward both sides on the top of the bottom plate 12. When the support column 15 drives the moving seat 13 to abut against the edge of the bottom plate 12, the two ends of the pressure column 16 are respectively installed at the top of the pressure seat 14 and the bottom edge of the support plate 3, and then a reinforcing column 17 is movably installed between the side wall of the pressure column 16 and the bottom of the support plate 3 near the middle, so that the reinforcing column 17, the pressure column 16 and the support plate 3 form a triangular structure, thereby improving the stability of the support plate 3, and the pressure exerted on the support plate 3 and the cross beam 2 will be dispersed to multiple support columns 15 and the bottom plate 12, thereby avoiding the cross beam 2 and the support plate 3 being subjected to excessive pressure and bending damage, and the vertical beam 1 and the bottom plate 12 are also installed together by screws and nuts, so the vertical beam 1, cross beam 2, load-bearing assembly and support assembly in this application can be installed and disassembled, so it is convenient to disassemble and transport the steel structure.

[0056] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; all technical solutions and improvements that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
