Description

Technical Field

[0001] This utility model belongs to the technical field of I-beam and column technology, specifically an I-beam and column connection structure. Background Technology

[0002] I-beams, also known as steel beams, are long steel bars with an I-shaped cross-section, mainly composed of two flanges (upper flange and lower flange) and a web in the middle.

[0003] In modern construction engineering, I-beams are widely used in beam and column structures due to their excellent mechanical properties, such as high bending strength and good load-bearing capacity, as well as relatively high economic efficiency. As a key node in the building structural system, the performance of I-beam beam-column connections directly affects the overall safety and stability of the building.

[0004] The connection methods for I-beams and columns are typically welding, bolting, and a combination of bolting and welding. During the installation of I-beams and columns, the I-beams are usually hoisted horizontally and then mated with the columns at a high altitude. However, traditional I-beam-column connections lack accurate and reliable positioning structures for the I-beams and columns, requiring repeated adjustments to the hoisting position and height. This makes the mating and installation inconvenient, inefficient, and significantly increases safety risks due to prolonged work at height. Utility Model Content

[0005] To address the problems of traditional I-beam-column connections, which lack accurate and reliable positioning structures, resulting in inconvenient installation, low construction efficiency, and significantly increased safety risks due to prolonged high-altitude work, this invention provides an I-beam-column connection structure.

[0006] This utility model is achieved through the following technical solution:

[0007] An I-beam-column connection structure includes an I-beam column and an I-beam, and further includes:

[0008] A first mounting plate is fixedly connected to the flange of the I-beam column. A positioning slot is provided on the upper side of the first mounting plate, and chamfers are provided on both sides of the upper part of the positioning slot.

[0009] An extension that is connected to the end of the web of the I-beam and protrudes outwards, with the lower part of the positioning slot able to be engaged and positioned with the extension;

[0010] A second mounting plate is horizontally and vertically fixedly connected to the first mounting plate. The second mounting plate can fit against and support the lower flange of the I-beam and be fixedly connected.

[0011] A seventh mounting plate is fixedly connected to both sides of the web of the I-beam. A sixth mounting plate, which can be fixedly connected to the first mounting plate, is vertically fixed to one end of the seventh mounting plate near the I-beam column.

[0012] A further improvement of this utility model is that a third mounting plate is fixedly connected to the upper wing plate of the I-beam, and a vertical fourth mounting plate is fixedly connected to one end of the third mounting plate near the I-beam column. The lower part of the fourth mounting plate is provided with a locking part that can engage with the upper part of the positioning slot for positioning, and the fourth mounting plate can be fixedly connected to the wing plate of the I-beam column.

[0013] A further improvement of this utility model is that a fifth mounting plate is fixedly connected to the side of the fourth mounting plate away from the I-beam column, and the lower part of the fifth mounting plate can be fixedly connected to the upper part of the first mounting plate.

[0014] A further improvement of this utility model is that a first stiffening plate is provided to support the lower side of the first mounting plate and the second mounting plate.

[0015] A further improvement of this utility model is that a second rib is provided to support the connection between the upper side of the third mounting plate and the fourth mounting plate.

[0016] A further improvement of this utility model is that a third rib is provided to support the connection between the sixth mounting plate and the seventh mounting plate.

[0017] A further improvement of this utility model is that a number of I-beam reinforcing plates are fixedly connected between the two flanges of the I-beam column, and the I-beam reinforcing plates correspond to the installation positions of the I-beam beams.

[0018] A further improvement of this utility model is that the extension is integrally formed with the web of the I-beam.

[0019] Further improvements to this utility model include: the first mounting plate is bolted to the flange of the I-beam column; the second mounting plate is bolted to the lower flange of the I-beam; the third mounting plate is bolted to the upper flange of the I-beam column; the seventh mounting plates on both sides are bolted to the web of the I-beam column; the fifth mounting plate, the fourth mounting plate, and the flange of the I-beam column are bolted together; and the sixth mounting plate, the first mounting plate, and the flange of the I-beam column are bolted together.

[0020] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0021] During the installation of the I-beam column and I-beam, the I-beam is lifted so that the extension is positioned above the positioning slot. The lifted I-beam is then slowly lowered, and the extension, guided by the chamfered top of the positioning slot, falls into the lower part of the slot, achieving engagement and positioning. At this point, the second mounting plate is precisely aligned with and supports the lower flange of the I-beam, and the two are fixedly connected by welding or bolts. Similarly, the sixth mounting plate is aligned with the flange of the I-beam column, and the two are fixedly connected by welding or bolts. This I-beam column connection structure, through the guiding positioning of the extension via the positioning slot, ensures the accuracy and reliability of the I-beam and I-beam column docking, improving the convenience and efficiency of the installation and reducing the safety risks associated with prolonged high-altitude operations. Furthermore, the second mounting plate supports and fixes the lower flange of the I-beam, and the sixth mounting plate is aligned and fixed with the flange of the I-beam column, ensuring a reliable and stable connection between the I-beam and I-beam column.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] like Figure 1-5 As shown, this utility model discloses an I-beam-column connection structure, including an I-beam column 1 that is vertically fixed and installed, and an I-beam 2 that is horizontally installed. This I-beam-column connection structure also includes:

[0031] The first mounting plate 3 is fixedly attached to the wing plate of the I-beam column 1 (right wing plate of 1-3 in the figure). The upper part of the first mounting plate 3 is provided with a positioning groove 32. The upper part of the positioning groove 32 is open and has a large chamfer, thus forming a Y shape.

[0032] An extension 21 is connected to the end of the web of the I-beam 2 and protrudes out (protruding from the two flanges of the I-beam 2). The lower part of the positioning slot 32 can be engaged and positioned with the extension 21.

[0033] A second mounting plate 4 is horizontally and vertically fixedly connected to the middle of the first mounting plate 3. The second mounting plate 4 can fit and support the lower wing plate of the I-beam 2 and be fixedly connected.

[0034] The seventh mounting plate 9 is fixedly connected to both sides of the web of the I-beam 2. The end of the seventh mounting plate 9 closest to the I-beam column 1 is vertically fixedly connected to the sixth mounting plate 8, which can be fixedly connected to the first mounting plate 3.

[0035] The second mounting plate 4 is welded and fixed to the first mounting plate 3, and the first mounting plate 3 is pre-installed and fixed to the outer side of the wing plate of the I-beam column 1; the sixth mounting plate 8 is welded and fixed to the seventh mounting plate 9 (or is an angle steel), and the seventh mounting plate 9 is pre-installed and fixed to both sides of the web plate of the I-beam beam 2; when the I-beam column 1 and the I-beam beam 2 are connected and installed, the I-beam beam 2 is lifted up so that the extension 21 is on the upper side of the positioning slot 32, and the lifted I-beam beam 2 is slowly lowered. Under the guidance of the chamfer on the upper part of the positioning slot 32, the extension 21 falls into the lower part of the positioning slot 32, realizing the engagement and positioning of the extension 21 with the lower part of the positioning slot 32; at this time, the second mounting plate 4 is just attached to the lower wing plate of the I-beam beam 2 for support, and the two are fixedly connected by welding or bolting. Similarly, at this time, the sixth mounting plate 8 is attached to the wing plate of the I-beam column 1, and the two are fixedly connected by welding or bolting. This I-beam-column connection structure, through the positioning slot 32 guiding and positioning the extension 21, can achieve the accuracy and reliability of the docking positioning of the I-beam 2 and the I-beam column 1, improve the convenience and efficiency of docking and installation, and reduce the safety risks caused by long-term high-altitude operations; through the second mounting plate 4 supporting and fixing the lower wing plate of the I-beam 2, and through the sixth mounting plate 8 fitting and fixing the wing plate of the I-beam column 1, the reliable and stable connection between the I-beam 2 and the I-beam column 1 can be achieved.

[0036] The length of the extension 21 (i.e., the protrusion distance) is the same as the thickness of the positioning slot 32 (first mounting plate 3), which facilitates the extension 21 to fall (slide) and connect with the surface of the wing plate of the I-beam column 1, so that the ends of the two wing plates of the I-beam beam 2 are in contact with the first mounting plate 3, and at the same time, the ends of the extension 21 are in contact with the wing plate of the I-beam column 1, so as to achieve reliable and stable connection.

[0037] In another embodiment of this utility model, a third mounting plate 5 is fixedly connected to the upper flange of the I-beam 2. A vertical fourth mounting plate 6 is fixedly connected to one end of the third mounting plate 5 near the I-beam column 1. The lower part of the fourth mounting plate 6 has a locking part that can engage with the upper part of the positioning slot 32 for positioning, and the fourth mounting plate 6 can be fixedly connected to the flange of the I-beam column 1. The fourth mounting plate 6 is welded to the third mounting plate 5 (or is made of angle steel). The third mounting plate 5 is pre-installed and fixed to the upper part of the upper flange of the I-beam 2. The fourth mounting plate 6 is positioned by engaging with the upper part of the positioning slot 32 through the lower locking part, effectively preventing shaking and displacement. The fourth mounting plate 6 is fixedly connected to the flange of the I-beam column 1 (by welding or bolting), forming a tight whole, improving the mechanical performance of the I-beam-column connection structure, thereby enhancing the overall safety and stability of the building.

[0038] Furthermore, the thickness of the fourth mounting plate 6 is the same as that of the first mounting plate 3, which effectively facilitates the docking process, and the alignment of the fourth mounting plate 6 with the first mounting plate 3 is used to determine whether the I-beam column 1 is fully docked.

[0039] Furthermore, the fourth mounting plate 6 is fixedly connected (welded or bolted) to the side away from the I-beam column 1 by a fifth mounting plate 7. The lower part of the fifth mounting plate 7 can be fixedly connected (welded or bolted) to the upper part of the first mounting plate 3. This effectively enhances the stability of the connection, enabling the connection structure to withstand greater loads, improving the overall integrity of the structure, and helping to improve the performance of key nodes in the building structural system.

[0040] A second stiffening plate 51 supports the connection between the upper side of the third mounting plate 5 and the fourth mounting plate 6. A fifth mounting plate 7 is welded to both sides of the second stiffening plate 51. This enhances the structural strength of the connection between the third mounting plate 5 and the fourth mounting plate 6, effectively dispersing stress at the connection and preventing deformation or damage due to stress concentration. This ensures the reliability of the connection between the upper flange of the I-beam 2 and the I-beam column 1. Furthermore, by strengthening the connection between the third mounting plate 5 and the fourth mounting plate 6, the connection between the upper flange of the I-beam 2 and the flange of the I-beam column 1 becomes more stable, further improving the stability of the entire I-beam-column connection structure. When the building structure is subjected to various loads, they can work together better, ensuring the integrity of the structure and thus improving the overall safety and stability of the building.

[0041] A first stiffening rib 31 is provided to support the lower sides of the first mounting plate 3 and the second mounting plate 4. The first stiffening rib 31 effectively enhances the structural strength of the connection between the first mounting plate 3 and the second mounting plate 4, preventing deformation or damage to the connection due to stress concentration, thereby improving the load-bearing capacity and stability of the entire I-beam column connection structure.

[0042] A third stiffening plate 81 supports the connection between the sixth mounting plate 8 and the seventh mounting plate 9. This reinforcement effectively strengthens the connection between the sixth mounting plate 8 and the seventh mounting plate 9, preventing damage due to excessive stress and ensuring the reliability of the connection structure. The reinforcement of the connection node between the web of the I-beam 2 and the flange of the I-beam column 1 significantly improves the stability of the entire I-beam-column connection structure at this location. When the building structure is subjected to external forces, it can better transfer and disperse stress, enhancing the overall connection structure's resistance to deformation and damage.

[0043] Among them, several H-beam column reinforcing plates 11 are welded between the two flanges of the H-beam column 1, arranged vertically and at intervals. The H-beam column reinforcing plates 11 correspond to the installation positions of the H-beam beam 2. The structural reinforcement of the connection parts of the H-beam beam 2 improves the stiffness and strength of the connection points of the H-beam column 1, enhances the load-bearing capacity and stability of the H-beam column 1 itself, and enables it to better resist deformation when bearing the load transmitted from the H-beam beam 2, preventing the H-beam column 1 from local instability or failure due to excessive stress.

[0044] The extension 21 is integrally formed with the web of the I-beam 2. That is, the extension 21 is part of the web of the I-beam 2. Compared with forming the extension 21 by splicing or other methods, the integrally formed structure eliminates the weak links that may exist at the splicing points and avoids the problem of insufficient connection strength caused by the splicing process, thereby improving the reliability of the connection between the extension 21 and the web of the I-beam 2.

[0045] The first mounting plate 3 is bolted to the flange of the I-beam column 1; the second mounting plate 4 is bolted to the lower flange of the I-beam 2; the third mounting plate 5 is bolted to the upper flange of the I-beam column 1; the seventh mounting plates 9 on both sides are bolted to the web of the I-beam column 1; the fifth mounting plate 7, the fourth mounting plate 6, and the flange of the I-beam column 1 are bolted together; and the sixth mounting plate 8, the first mounting plate 3, and the flange of the I-beam column 1 are bolted together. This bolted connection method eliminates the need for complex welding equipment and processes during the installation of the I-beam beam-column connection structure, simplifying the operation and allowing construction personnel to easily assemble the components, thus improving construction efficiency. Furthermore, in later maintenance, repairs, or structural modifications, if disassembly of the I-beam beam-column connection structure is required, the bolted connection facilitates quick disassembly, reducing maintenance costs and difficulty. Bolted connections allow for precise control of the tightness of the connection between components by adjusting parameters such as bolt tightening torque. This ensures the installation accuracy of the I-beam-column connection structure. Compared to welding, which can be affected by factors such as thermal deformation, bolted connections are more conducive to ensuring accurate alignment between the I-beam 2 and I-beam column 1, guaranteeing the quality of the entire connection structure and thus ensuring the safety and stability of the building structure. Furthermore, standardized bolted connections provide better versatility and interchangeability for the components of the I-beam-column connection structure, which helps improve the maintenance efficiency and service life of the building structure.

[0046] Furthermore, all bolts used are high-strength bolts to ensure the strength of the connection.

[0047] In this I-beam column connection structure, when installing the I-beam column 1 and the I-beam 2, the I-beam 2 is lifted up so that the extension 21 is on the upper side of the positioning slot 32. The lifted I-beam 2 is then slowly lowered, and the extension 21 falls into the lower part of the positioning slot 32 under the guidance of the chamfer on the upper part of the positioning slot 32, thus achieving the engagement and positioning of the extension 21 with the lower part of the positioning slot 32. At this time, the second mounting plate 4 is attached to and supports the lower wing plate of the I-beam 2, and the two are fixedly connected by welding or bolts. Similarly, at this time, the sixth mounting plate 8 is attached to the wing plate of the I-beam column 1, and the two are fixedly connected by welding or bolts. This I-beam-column connection structure, through the positioning slot 32 guiding and positioning the extension 21, can achieve the accuracy and reliability of the docking positioning of the I-beam 2 and the I-beam column 1, improve the convenience and efficiency of docking and installation, and reduce the safety risks caused by long-term high-altitude operations; through the second mounting plate 4 supporting and fixing the lower wing plate of the I-beam 2, and through the sixth mounting plate 8 fitting and fixing the wing plate of the I-beam column 1, the reliable and stable connection between the I-beam 2 and the I-beam column 1 can be achieved.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
