Technical Field
[0001] This utility model relates to the field of steel structure frame technology, and in particular to a modular steel structure frame that is easy to assemble. Background Technology
[0002] A steel frame structure is a spatial skeleton system composed of steel (section steel, steel plates, etc.) as the main load-bearing components, connected by welding, bolting, or other methods. It is characterized by high strength, light weight, and good seismic performance, making it suitable for large-span, high-rise, and industrial buildings. The main body consists of steel columns, steel beams, steel trusses, and other components, with rigid or hinged connections at joints to form a stable load-bearing system. It combines the advantages of factory prefabrication and on-site assembly, conforms to green building principles, and requires anti-corrosion and fireproofing treatment to ensure durability.
[0003] A search revealed a steel structure frame (authorization announcement number: CN 218714846 U), which "includes mounting frames, an erection mechanism, and installation components. The mounting frames are in two sets arranged opposite to each other; the erection mechanism is located between the two sets of mounting frames and includes mounting rods, mounting plates, mounting ladders, and placement plates. Mounting rods are fixedly installed on the inner side of the mounting frames, mounting plates are erected between the two sets of mounting rods, and an installation ladder is fixedly installed at the bottom of the mounting plates. Two sets of placement plates are erected between the two sets of mounting frames, arranged vertically. This steel structure frame can be erected by inserting mounting nails into the ground to fix the connecting plates, setting up mounting frames inside the mounting cylinder, erecting mounting plates between the two sets of mounting rods, erecting placement plates between the two sets of mounting frames, and threading screws into threaded holes to install the frame. It can also release a protective net by turning a crank handle to protect against external objects."
[0004] Based on the aforementioned technologies, the applicant believes that existing steel structure frames mostly use bolts for installation and fixation. During the installation process, the bolts need to be tightened dozens of times with the aid of tools, which is labor-intensive and not conducive to rapid splicing and installation. Moreover, the bolts are exposed to the outside for a long time, and are prone to rust due to wind and sun exposure, making the frame difficult to dismantle. This makes it difficult to meet the needs of modular buildings. In response to the above problems, we have launched a modular steel structure frame that is easy to splice. Utility Model Content
[0005] This utility model discloses a modular steel structure frame that is easy to assemble, aiming to solve the technical problems of existing steel structure frames that mostly use bolts for installation and fixation. During the installation process, the bolts need to be tightened dozens of times with the help of tools, which is labor-intensive and not conducive to rapid assembly and installation. Moreover, the bolts are exposed to the outside for a long time, and are prone to rust due to wind and sun, making the frame difficult to disassemble.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A modular steel structure frame for easy assembly includes vertical columns, with horizontal columns on the outer side of each vertical column. A mounting sleeve is slidably connected to the outer side of each vertical column. A mounting block is fixedly connected to the side of the mounting sleeve away from the horizontal column. The mounting block contains a pushing mechanism and a locking mechanism that cooperate with each other. The pushing mechanism includes a fixing groove located on the side of the mounting block closest to the vertical column. A sliding frame is symmetrically slidably connected inside the fixing groove. A telescopic groove is symmetrically formed on one side of the fixing groove. A fixing plate is fixedly connected to one side of the inner wall of each of the two telescopic grooves. A pushing spring is fixedly connected to the other side of each of the two fixing plates. The other end of the pushing spring is fixedly connected to the sliding frame. Fixing holes are symmetrically formed inside the horizontal column.
[0008] The modular steel structure can be quickly assembled using the locking mechanism. The entire assembly process requires no welding or complicated tools; installation or disassembly can be completed simply by pushing and pulling, which greatly improves construction efficiency. The structure is simple and highly practical.
[0009] In a preferred embodiment, the locking mechanism includes a lifting groove symmetrically formed on both sides of the inner wall of the fixed groove. A fixed frame is symmetrically fixedly connected to the outer side of the mounting block. Sliding columns are slidably connected inside each of the two fixed frames. Limiting discs are fixedly connected to the outer sides of each of the two sliding columns. A pressing spring is sleeved on the outer side of each of the two sliding columns. The ends of the two sliding columns that are close to each other extend into the interior of the lifting groove and are fixedly connected to a pressing ball. Spherical grooves are formed on the sides of the two sliding frames that are far apart from each other. The spherical grooves and pressing balls cooperate with each other.
[0010] The locking mechanism, consisting of a lifting groove, a fixed frame, a sliding column, a limiting plate, a pressing spring, a pressing ball, and a spherical groove, forms a double locking mechanism to achieve self-locking, prevent the transverse column from accidentally coming out, and improve the overall frame's seismic resistance and safety.
[0011] In a preferred embodiment, slots are provided at equal intervals inside the vertical column, the size of the slots is consistent with the size of the horizontal column, the slots and the horizontal column are used in conjunction with each other, the inner wall of the slots is symmetrically fixedly connected with fixing plates, and the two fixing plates on the same side are symmetrically fixedly connected with reinforcing ribs, the reinforcing ribs are arranged in an X shape.
[0012] The slots inside the vertical columns match the dimensions of the horizontal columns. Combined with fixing plates and X-shaped reinforcing ribs, the joint strength is enhanced, load stress is distributed, and local deformation is prevented. It is especially suitable for high-rise or large-span steel structure scenarios.
[0013] In a preferred embodiment, the inner wall of the mounting sleeve is symmetrically provided with sliding grooves on both sides, and the vertical column is symmetrically fixedly connected with sliding rails on both sides, and the sliding rails and sliding grooves are used in cooperation with each other.
[0014] The sliding groove of the mounting sleeve slides in conjunction with the slide rail of the vertical column, enabling stepless adjustment of the horizontal column height to adapt to different floor height requirements. At the same time, the guide design of the slide rail avoids misalignment during splicing.
[0015] In a preferred embodiment, each of the two sliding pins has a pull ring fixedly connected to its opposite ends.
[0016] The pull ring at the end of the sliding column facilitates manual operation of the locking mechanism, allowing for unlocking and disassembly without tools, thus improving the reusability and maintenance efficiency of the modular frame.
[0017] In a preferred embodiment, the mounting sleeve is fixedly connected to a reinforcing sleeve for lateral support of the transverse column on the side near the transverse column.
[0018] Strengthening the sleeve wrapping the end of the transverse column increases the bending stiffness of the joint, reduces flexural deformation under transverse loads, and extends service life.
[0019] The modular steel structure frame provided by this utility model, which is easy to assemble, has the following advantages:
[0020] Firstly, the modular steel structure can be quickly assembled using the locking mechanism. The entire assembly process requires no welding or complex tools; installation or disassembly can be completed simply by pushing and pulling, greatly improving construction efficiency. The structure is simple and highly practical.
[0021] Secondly, the sliding groove of the mounting sleeve slides in conjunction with the sliding rail of the vertical column, realizing stepless adjustment of the horizontal column height to adapt to different floor height requirements. At the same time, the guide design of the sliding rail avoids splicing misalignment, and the pull ring at the end of the sliding column facilitates manual operation of the locking mechanism. Unlocking and disassembly can be carried out without tools, improving the reusability and maintenance efficiency of the modular frame. The sleeve wraps around the end of the horizontal column, increasing the bending stiffness of the node, reducing the flexural deformation under lateral load, and extending the service life.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0030] The modular steel structure frame disclosed in this utility model is easy to assemble and is mainly used in steel structure frame scenarios.
[0031] Reference Figures 1-6A modular steel structure frame that is easy to assemble includes a vertical column 1, a horizontal column 2 on the outer side of the vertical column 1, a mounting sleeve 3 slidably connected to the outer side of the vertical column 1, and a mounting block 4 fixedly connected to the side of the mounting sleeve 3 away from the horizontal column 2. The mounting block 4 has a pushing mechanism and a locking mechanism inside, which cooperate with each other. The pushing mechanism includes a fixing groove 51, which is opened on the side of the mounting block 4 near the vertical column 1. A sliding frame 52 is symmetrically slidably connected inside the fixing groove 51. A telescopic groove 53 is symmetrically opened on one side of the inside of the fixing groove 51. A fixing plate 54 is fixedly connected to one side of the inner wall of each of the two telescopic grooves 53. A pushing spring 55 is fixedly connected to the other side of each of the two fixing plates 54. The other end of the pushing spring 55 is fixedly connected to the sliding frame 52. A fixing hole 56 is symmetrically opened inside the horizontal column 2. The locking mechanism includes lifting grooves 61, which are symmetrically located on both sides of the inner wall of the fixed groove 51. Fixed frames 62 are symmetrically fixedly connected to the outer side of the mounting block 4. Sliding pillars 63 are slidably connected inside both fixed frames 62. Limiting discs 64 are fixedly connected to the outer sides of both sliding pillars 63. Pressing springs 65 are sleeved on the outer sides of both sliding pillars 63. The ends of the two sliding pillars 63 that are close to each other extend into the interior of the lifting groove 61 and are fixedly connected to pressing balls 66. Spherical grooves 67 are opened on the sides of the two sliding frames 52 that are far apart from each other. The spherical grooves 67 and pressing balls 66 cooperate with each other. Slots 7 are equidistantly opened inside the vertical column 1. The size of the slots 7 matches the size of the horizontal column 2. The slots 7 and the horizontal column 2 cooperate with each other. Fixed plates 8 are symmetrically fixedly connected to the inner wall of the slots 7. Reinforcing ribs 9 are symmetrically fixedly connected between the two fixed plates 8 on the same side. The reinforcing ribs 9 are X-shaped.
[0032] In this embodiment: the horizontal column 2 is inserted into the slot 7 of the vertical column 1. Because the slot 7 contains a fixing plate 8 and an X-shaped reinforcing rib 9, the horizontal column 2 can maintain stable alignment during insertion, preventing displacement. The mounting sleeve 3 slides with the slide rail 11 of the vertical column 1 via the sliding groove 10, allowing the horizontal column 2 to be adjusted up and down along the vertical column 1 to the desired height. When the horizontal column 2 is fully inserted, the pushing mechanism within the mounting block 4 begins to function: the sliding frame 52 contracts inward within the fixing groove 51 due to the pressure of the horizontal column 2, compressing the pushing spring 55 to store energy. When the horizontal column 2 is fully inserted, the pressing ball 66 moves out of the spherical groove 67... When the internal detachment occurs and the sliding frame 52 moves, the spherical groove 67 on its side aligns with the pressing ball 66. Under the action of the pressing spring 65, the pressing ball 66 automatically embeds into the fixing hole 56, forming a mechanical self-locking mechanism to prevent the transverse column 2 from accidentally retracting from the slot 7. The limiting plate 64 restricts the stroke of the sliding column 63, ensuring that the pressing ball 66 always maintains stable contact with the spherical groove 67. Through the locking mechanism, the modular steel structure can be quickly assembled. The entire assembly process requires no welding or complex tools; installation or disassembly can be completed simply by pushing and pulling, greatly improving construction efficiency. The structure is simple and highly practical.
[0033] In the above technical solution, considering that existing steel structure frames mostly use bolts for installation and fixation, requiring dozens of bolt tightening operations with tools during installation, resulting in a large workload and hindering rapid assembly, and that bolts exposed to the elements for extended periods are prone to corrosion, making the frame difficult to disassemble, the following specific operation is proposed to solve these problems:
[0034] Reference Figures 1-6 In a preferred embodiment, the inner wall of the mounting sleeve 3 is symmetrically provided with grooves 10 on both sides, and slide rails 11 are symmetrically fixedly connected to both sides of the vertical column 1. The slide rails 11 and the grooves 10 cooperate with each other. Pull rings 68 are fixedly connected to the ends of the two sliding columns 63 that are far apart from each other. A reinforcing sleeve 12 for lateral support of the horizontal column 2 is fixedly connected to the side of the mounting sleeve 3 near the horizontal column 2.
[0035] In this embodiment, the sliding groove 10 of the mounting sleeve 3 slides in conjunction with the sliding rail 11 of the vertical column 1, enabling stepless adjustment of the height of the horizontal column 2 to adapt to different floor height requirements. At the same time, the guide design of the sliding rail 11 avoids misalignment during splicing. The pull ring 68 at the end of the sliding column 63 facilitates manual operation of the locking mechanism, allowing for unlocking and disassembly without tools, thus improving the reusability and maintenance efficiency of the modular frame. The reinforced sleeve 12 wraps around the end of the horizontal column 2, increasing the bending stiffness of the joint, reducing flexural deformation under lateral loads, and extending the service life.
[0036] Working principle: When assembling this modular steel structure frame, the horizontal column 2 is first inserted into the slot 7 of the vertical column 1. Because the slot 7 contains a fixing plate 8 and an X-shaped reinforcing rib 9, the horizontal column 2 maintains stable alignment during insertion, preventing displacement. The mounting sleeve 3 slides with the slide rail 11 of the vertical column 1 via the sliding groove 10, allowing the horizontal column 2 to be adjusted up and down along the vertical column 1 to the required height. After the horizontal column 2 is fully inserted, the pushing mechanism in the mounting block 4 begins to function: the sliding frame 52 contracts inward under the pressure of the horizontal column 2 within the fixing groove 51, compressing the pushing spring 55 to store energy. When the horizontal column 2 is fully inserted, the pressing ball 66 disengages from the inside of the spherical groove 67. As the sliding frame 52 moves, the spherical groove 67 on its side aligns with the pressing ball 66. The pressing ball 66 automatically embeds into the fixing hole 56 under the action of the pressing spring 65, forming a mechanical self-locking mechanism to prevent the horizontal column 2 from accidentally retracting from the slot 7. The limiting plate 64 restricts the stroke of the sliding column 63, ensuring that the pressing ball 66 always maintains stable contact with the spherical groove 67. If disassembly is required, simply pull the pulling ring 68 outward to make the sliding column 63 drive the pressing ball 66 out of the fixing hole 56 to release the lock. The horizontal column 2 can then be pulled out in the opposite direction. The reinforcing sleeve 12 wraps around the end of the horizontal column 2 to enhance the bending resistance of the joint. The X-shaped reinforcing rib 9 inside the vertical column 1 effectively disperses stress and improves the overall load-bearing capacity and seismic performance of the structure. The entire splicing process does not require welding or complex tools; installation or disassembly can be completed simply by pushing and pulling, greatly improving construction efficiency.
[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
