Description

TECHNICAL FIELD

[0001] The utility model relates to a steel structure beam column technical field especially relates to a steel structure factory building beam column. BACKGROUND

[0002] In industrial plant construction, large equipment support structure assembly, plant renovation and expansion, and subsequent maintenance and repair, the ease of installation, connection stability, and structural safety of steel structure beams and columns directly affect the load-bearing capacity and long-term reliability of the overall plant structure. With the expansion of industrial production scale and the upgrading of plant functional requirements, steel structure plants increasingly demand higher assembly efficiency and stability for beams and columns: large plants require rapid connection and fixing of multiple sets of I-beams and columns to shorten construction cycles; heavy equipment workshops require beams and columns with strong load-bearing capacity to cope with equipment operating loads; and renovated and expanded plants require flexible and adaptable beam-column connection structures. However, current methods for connecting beams and columns in most steel structure plants either rely on single bolt fixation, which is prone to loosening and deformation under long-term stress; or lack precise positioning structures, requiring repeated calibration of hole positions during installation, resulting in low work efficiency; or lack additional reinforcement and protection designs, making it difficult to remedy loosening of the initial fixing structure. This places higher demands on the positioning accuracy, fixing stability, and installation convenience of steel structure beams and columns, urgently requiring structural optimization and innovation to meet the diverse usage needs of industrial scenarios. CN217175205U discloses a method for fixing I-beams in factory steel structures using a combination of rectangular beams / columns, triangular support plates, bracing plates, and U-shaped frames. However, this method suffers from significant shortcomings in installation efficiency and stability. The core structure comprises rectangular beams / columns, triangular support plates, bracing plates, U-shaped frames, I-beam frames, and main and auxiliary clamps. The U-shaped frames and bracing plates form I-beam slots. After the I-beam frame is inserted into the slot, it is fixed using bolts and nuts with multiple sets of fixing holes. The main and auxiliary clamps are further reinforced with clamps. During operation, the I-beam frame is inserted into the I-beam slot, aligned with the fixing holes, and then tightened with bolts and nuts. The main and auxiliary clamps, through protrusions and clamps in conjunction with the fixing slots, provide additional support to the outer wall of the bracing plate. While this method can meet the beam-column connection requirements of the foundation, it suffers from significant deficiencies in positioning efficiency, fixing reliability, and ease of operation, failing to meet the demands of efficient construction and long-term stable load-bearing. The steel structure beams and columns of the factory building described in announcement number CN217175205U suffer from low installation efficiency, insufficient structural stability, and high operational difficulty. It lacks a dedicated rapid positioning structure; the I-beams require repeated calibration of multiple sets of fixing holes after insertion into I-beam slots to complete bolt installation, significantly extending the construction period. The fixing method is simplistic, relying solely on bolts and nuts to connect the fixing holes. Under long-term exposure to factory loads or environmental vibrations, the bolts are prone to deformation and loosening, leading to a continuous decline in structural stability. After the initial fixing structure loosens, there is a lack of effective secondary reinforcement mechanisms to promptly fill connection gaps, posing safety hazards. Furthermore, the device involves multiple sets of linearly arrayed fixing holes, making the threaded installation process cumbersome. It requires precise manual alignment of multiple sets of holes and individual bolt tightening, greatly increasing the difficulty and intensity of manual work, making it unsuitable for large-scale factory construction or high-altitude operations. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0004] This utility model adopts the following technical solution: a steel structure factory beam and column, including a steel beam main frame and an overlapping platform. The overlapping platform is fixedly installed at the top of the steel beam main frame. A triangular beam is fixedly installed at the bottom of the overlapping platform. One end of the triangular beam is fixedly installed on the side of the steel beam main frame. A fixing block is fixedly installed above the overlapping platform. A limit rod and a motor are fixedly installed on the surface of the fixing block. A bidirectional lead screw is fixedly installed at the output end of the motor. A positioning plate is threadedly connected to the surface of the bidirectional lead screw. A protrusion is fixedly installed on the surface of the positioning plate. A positioning hole is opened on the surface of the positioning plate.

[0005] Preferably, the positioning plates have two sets threaded connections to both ends of the bidirectional lead screw. An I-shaped steel beam abuts between each pair of positioning plates. The protrusions perfectly fit the side grooves of the I-shaped steel beam, and a limiting plate is fixedly installed on one side of the protrusions. Here, the motor drives the bidirectional lead screw to move the two sets of positioning plates relative to each other. The protrusions precisely fit the side grooves of the I-shaped steel beam, and the limiting plate quickly forms a limiting slot. Unlike reference devices, there is no need for repeated hole calibration, allowing for direct and rapid positioning of the I-shaped steel beam. After positioning, the lead screw locks, completing the first step of fixing, significantly improving installation efficiency. Simultaneously, the limiting plate restricts the lateral displacement of the steel beam, enhancing structural stability from the positioning stage.

[0006] Preferably, the positioning holes penetrate the positioning plate, the protrusion, and the side groove of the I-beam. A threaded rod is threaded into the positioning hole, and a fastening nut is threaded to the end of the threaded rod. The threaded rods are arranged in a linear array and threaded into the positioning holes on the outer surface of the positioning plate. Here, the linearly arrayed positioning holes, threaded rods, and fastening nuts cooperate to complete the second-step fixing by passing through the pre-reserved installation holes in the side groove of the steel beam. Compared to the single bolt fixing of the reference device, the connection is tighter and the operation is more convenient. The motor drive replaces some manual operation, reducing the difficulty and complexity of manual work. The two-step fixing mechanism also avoids the long-term bolt deformation problem caused by the single fixing method of the reference device, further improving structural stability.

[0007] Preferably, there are four sets of overlapping platforms, arranged in a circular array around the top of the main steel beam frame. Each set of overlapping platforms has a set of I-beams fixedly installed, with both ends of the I-beams secured by the overlapping platforms. Here, the four sets of circularly arrayed overlapping platforms can simultaneously accommodate the installation of four I-beams, and both ends of the steel beams are secured by the overlapping platforms. Compared to the reference device, this facilitates the orderly arrangement of multiple steel beams. The standardized overlapping platform structure facilitates mass production and installation, solving the problem of inconsistent coordination when installing multiple steel beams in the reference device, and significantly improving versatility and ease of installation.

[0008] Preferably, a support column is fixedly installed at the top of the main steel beam frame, and a diagonal brace is fixedly installed on the outer surface of the support column. An upper mating block is fixedly installed at the end of the diagonal brace, and a lower mating block abuts against the lower surface of the upper mating block. The upper and lower mating blocks are connected by two sets of threaded rods and fastening nuts. Here, the upper and lower mating blocks are locked by the threaded rods and fastening nuts, providing a third non-end locking for the steel beam. This compensates for the deficiency of the reference device having only one locking mechanism, effectively preventing initial loosening due to long-term stress, improving structural safety, and the supporting effect of the diagonal brace also enhances the load-bearing capacity of the mating blocks, making the locking more reliable.

[0009] Preferably, the limiting space formed between the upper and lower mating blocks is consistent with the cross-section of the I-beam. Four sets of the upper and lower mating blocks are arranged in a circular array and installed on the diagonal bracing around the support column. Here, the mating blocks are adapted to the cross-section of the steel beam, providing precise and stable additional support to the upper surface of the steel beam. This solves the problem that the reference device only supports the ends of the steel beam and the extension portion is insufficiently supported, resulting in more even stress distribution on the steel beam. The four sets of circularly arranged mating blocks correspond one-to-one with the overlapping platform, further ensuring the overall stability and coordination after the installation of multiple steel beams.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a highly efficient and stable connection system for the beams and columns of a steel structure factory building is formed by a steel beam main frame, an overlapping platform, a motor, a two-way lead screw, a positioning plate, a protrusion, and a threaded rod. During installation, the I-shaped steel beam is placed between two sets of positioning plates. The motor is started to drive the two-way lead screw to rotate, causing the positioning plates to move relative to each other. This allows the protrusion to precisely fit with the side groove of the I-shaped steel beam, and the limiting plate forms a limiting slot to complete the rapid positioning. The lead screw locks, achieving the first step of fixation. Subsequently, the threaded rod is passed through the positioning holes of the positioning plate, the protrusion, and the side groove of the I-shaped steel beam, and the fastening nut is tightened to complete the second step of fixation. This solution utilizes a rapid positioning structure consisting of a motor-driven bidirectional lead screw and a positioning plate protrusion, eliminating the need for repeated hole calibration as required by the reference device and significantly improving installation efficiency. The linearly arrayed threaded rods, in conjunction with the positioning holes, provide a tighter connection and easier operation compared to the reference device's single bolt fixation. The motor drive reduces manual operation, lowering the difficulty and complexity of the work. The two-step fixing mechanism avoids the long-term bolt deformation problem caused by the single fixing method in the reference device, improving structural stability and reducing safety hazards through multiple stages of positioning and fixing.

[0011] 2. In this utility model, a multi-layered reinforcement and collaborative support system for the beams and columns of a steel structure factory building is formed by the support columns and diagonal bracing beams at the top of the main steel beam frame, along with upper and lower mating blocks and multiple sets of overlapping platforms. After the I-shaped steel beams are initially fixed, the upper mating blocks at the ends of the diagonal bracing beams around the support columns abut against the upper surface of the steel beams. After the mating blocks are installed, the upper and lower mating blocks are locked with threaded rods and fastening nuts, achieving a third non-end fixation of the steel beams. Four sets of overlapping platforms arranged in a circumferential array correspond one-to-one with the mating blocks, fixing the two ends and extensions of the four I-shaped steel beams respectively. Compared with the limitations of the reference device, which only has one locking mechanism and only supports the ends of the steel beams, this solution effectively prevents the initial fixation from loosening due to long-term stress through the third locking of the upper and lower mating blocks, thus improving structural safety. The combination of diagonal bracing beams and mating blocks provides effective support for the extensions of the steel beams, solving the problem of uneven stress. The collaborative design of multiple standardized structures facilitates the unified and coordinated installation of multiple steel beams, significantly improving versatility and installation convenience, and adapting to the needs of large-scale factory construction.

Detailed Implementation

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Example 1 See Figures 1-3 A steel structure factory beam and column system includes a main steel beam frame 1 and an overlapping platform 2. The overlapping platform 2 is fixedly installed at the top of the main steel beam frame 1, and a triangular beam 3 is fixedly installed at the bottom of the overlapping platform 2. One end of the triangular beam 3 is fixedly installed on the side of the main steel beam frame 1. A fixing block 201 is fixedly installed above the overlapping platform 2. A limit rod 202 and a motor 203 are fixedly installed on the surface of the fixing block 201. A bidirectional lead screw 204 is fixedly installed at the output end of the motor 203. A positioning plate 205 is threadedly connected to the surface of the bidirectional lead screw 204. A protrusion 206 is fixedly installed on the surface of the positioning plate 205, and a positioning hole 207 is opened on the surface of the positioning plate 205. The positioning plate 205 has two sets of threads respectively connected to the two ends of the bidirectional lead screw 204. Each pair of positioning plates 205 abuts against an I-beam 4. The protrusion 206 is fully adapted to the side groove of the I-beam 4. A limit plate 208 is fixedly installed on one side of the protrusion 206. The positioning hole 207 penetrates the positioning plate 205, the protrusion 206, and the side groove of the I-beam 4. A threaded rod 209 is threaded into the positioning hole 207. A fastening nut 210 is threaded at the end of the threaded rod 209. The threaded rod 209 is threaded in a linear array into the positioning hole 207 on the outer surface of the positioning plate 205. There are four sets of overlapping platforms 2, which are distributed in a circumferential array around the top of the main steel beam frame 1. Each set of overlapping platforms 2 is fixedly installed with a set of I-beams 4. Both ends of the I-beams 4 are fixed by the overlapping platform 2. During installation, the I-beam 4 is first placed between two sets of positioning plates 205. The motor 203 is then started, driving the bidirectional lead screw 204 to rotate. This causes the two sets of positioning plates 205 to move relative to each other, allowing the protrusion 206 to precisely fit into the side groove of the I-beam 4. This, combined with the limiting plate 208, quickly forms a limiting slot, directly achieving rapid positioning of the I-beam 4 without the need for repeated hole calibration. After positioning, the lead screw locks in place, completing the first step of fixing and significantly improving installation efficiency. Subsequently, the threaded rod 209 is passed through the positioning holes 207 in the positioning plates 205, protrusion 206, and side groove of the I-beam 4. The fastening nut 210 is then tightened to complete the second step of fixing. The linearly arrayed threaded rods 209 engage with the positioning holes 207, resulting in a tighter connection compared to traditional single bolt fixing. Furthermore, the motor 203 drive replaces some manual operation, reducing the difficulty and complexity of manual work. Meanwhile, the four sets of overlapping platforms 2 arranged in a circular array can simultaneously accommodate the installation of four I-beams 4. Both ends of the I-beams 4 are fixed through the overlapping platforms 2, which facilitates the orderly layout of multiple steel beams. The standardized structure of the overlapping platforms 2 also facilitates mass production and installation, solving the problem of difficulty in unified coordination when installing multiple steel beams in the traditional way. This significantly improves versatility and ease of installation. The two-step fixing mechanism also avoids the problem of long-term stress bolt deformation caused by the single fixing method in the traditional way, improving the structural stability from multiple aspects such as positioning and fixing.

[0016] Example 2 refer to Figures 1-4 A support column 5 is fixedly installed on the top of the main steel beam 1. A diagonal brace 6 is fixedly installed on the outer surface of the support column 5. An upper mating block 601 is fixedly installed at the end of the diagonal brace 6. A lower mating block 602 abuts against the lower surface of the upper mating block 601. The upper mating block 601 and the lower mating block 602 are connected by two sets of threaded rods 209 and fastening nuts 210. The limiting space formed between the upper mating block 601 and the lower mating block 602 is consistent with the cross-section of the I-shaped steel beam 4. Four sets of upper mating blocks 601 and lower mating blocks 602 are arranged in a circumferential array and installed on the diagonal brace 6 around the support column 5. After the I-beam 4 is initially fixed in two steps via the overlapping platform 2, the upper mating block 601 at the end of the diagonal tie beam 6 around the support column 5 naturally abuts against the upper surface of the I-beam 4. At this time, the lower mating block 602 is placed against the lower surface of the I-beam 4, aligning the upper and lower mating blocks 601. The two are then threadedly connected and locked by two sets of threaded rods 209 and fastening nuts 210, achieving the third non-end fixing of the I-beam 4. This effectively prevents the initial fixing from loosening due to long-term stress, compensates for the shortcomings of the traditional single-set locking mechanism, and improves structural safety. The limiting space between the upper and lower mating blocks 601 and 602 is consistent with the cross-section of the I-beam 4, forming precise and stable additional support for the upper surface of the I-beam 4. This solves the problem of insufficient support for the traditional only ends and extensions of the steel beam, making the stress on the steel beam more even. Four sets of mating blocks arranged in a circular array correspond one-to-one with the overlapping platform 2, further ensuring the overall stability and coordination after the installation of multiple steel beams, and adapting to the needs of large-scale factory construction.

[0017] Working Principle: During the installation of the beams and columns of this steel structure factory building, the motor 203 drives the bidirectional lead screw 204 to move the positioning plate 205, so that the protrusion 206 matches the side groove of the I-beam 4 to form a limiting slot, completing the first step of rapid positioning and fixing. Then, the linearly arrayed threaded rods 209 cooperate with the positioning holes 207 to complete the second step of reinforcement and fixing. Finally, the support column 5, the diagonal tie beam 6, and the upper and lower mating blocks are used to achieve the third non-end locking and additional support for the I-beam 4. The four sets of circumferentially arrayed overlapping platforms 2 and the mating blocks work together to achieve the orderly installation and stable fixing of multiple I-beams 4. The whole process does not require complex calibration and tedious manual operation, which not only improves the installation efficiency and reduces the difficulty of operation, but also solves the problems of unstable fixing, uneven stress, and poor versatility of traditional structures through multiple fixing and collaborative support mechanisms, ensuring the overall stability and safety of the beams and columns of the steel structure factory building, and adapting to diverse factory building construction needs.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
