Description

Technical Field

[0001] This utility model relates to the field of H-beam technology, and in particular to a new type of earthquake-resistant H-beam. Background Technology

[0002] H-beams are steel sections with an H-shaped cross-section, also known as universal steel beams, wide-flange (side) I-beams, or parallel-flange I-beams. They have wider flanges and no slope on the inner side of the legs, making them easy to combine and connect with other components. They have a large section modulus and good properties, making them an economical steel profile and an ideal load-bearing frame steel for building structures. They have advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and have been widely used. Utility model patent application number CN201920587217.5 discloses a novel earthquake-resistant I-beam, comprising a first supporting beam, characterized in that: a web supporting vertical beam is fixedly connected to the bottom of the first supporting beam; a first C-shaped supporting steel plate is fixedly connected to one side of the web supporting vertical beam; a second C-shaped supporting steel plate is fixedly connected to the other side of the web supporting vertical beam; a second supporting beam is fixedly connected to the bottom of the web supporting vertical beam; a first fixing connecting block is fixedly connected to one side of the bottom of the first supporting beam; a second fixing connecting block is fixedly connected to the other side of the bottom of the first supporting beam; a third fixing connecting block is fixedly connected to one side of the top of the second supporting beam; a fourth fixing connecting block is fixedly connected to the other side of the top of the second supporting beam; one end of the first C-shaped supporting steel plate is fixedly connected to the first fixing connecting block. The system is as follows: one end of the first C-shaped support steel plate is fixedly connected to the second fixed connecting block; one end of the second C-shaped support steel plate is fixedly connected to the third fixed connecting block; and the other end of the second C-shaped support steel plate is fixedly connected to the fourth fixed connecting block. The first and second support beams each have several first mounting holes. The first, second, third, and fourth fixed connecting blocks each have second mounting holes. The diameters of the first and second mounting holes are equal. Fixing bolts are installed inside the first and second mounting holes. Both the first and second mounting holes have positive threads, and the outer surface of the fixing bolts has reverse threads, which are compatible. However, the first and second C-shaped support steel plates are connected and fixed using multiple fixing bolts, requiring a large number of bolts. This makes the installation and disassembly of the first and second C-shaped support steel plates cumbersome and time-consuming. Utility Model Content

[0003] This invention aims to solve the problems existing in the prior art by providing a new type of earthquake-resistant H-beam, which can improve the overall strength of the H-beam and effectively resist earthquakes. It is simple to install and easy to disassemble, saving time and manpower and improving operational efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This novel earthquake-resistant H-beam includes a web, a first flange, and a second flange. The web, the first flange, and the second flange are connected and fixed by welding. A first C-shaped plate is provided on one side of the web, and a second C-shaped plate is provided on the other side of the web. The first flange has two inwardly rolled edges with an inner groove inside. The second flange also has two inwardly rolled edges. The first C-shaped plate has two first protruding strips on its side, which are respectively inserted into the first flange and the second flange. In the inner groove, the second C-shaped plate has two second protruding strips on its side. These two second protruding strips are respectively inserted into the inner grooves of the first and second wing plates. Mounting holes are provided on the outer side of the inwardly rolled edge. The mounting holes have a convex structure. Threaded grooves are provided on the side of the first protruding strip. Fixing bolts are installed inside the mounting holes and connected to the threaded grooves. There are multiple mounting holes, threaded grooves, and fixing bolts. Multiple threaded grooves are also provided on the side of the second protruding strip. The first C-shaped plate is inserted between the first and second wing plates, and the two first protruding strips respectively enter the inner grooves of the two inwardly rolled edges until... Two first protruding strips are fully inserted into the inner groove. Multiple threaded grooves and multiple mounting holes are aligned with each other. Multiple fixing bolts are obtained, and multiple fixing bolts pass through multiple mounting holes. Multiple fixing bolts are threadedly connected to multiple threaded grooves. The first C-shaped plate is between the first wing plate and the second wing plate and is difficult to detach. The second C-shaped plate is inserted into the first wing plate and the second wing plate on the other side. Two second protruding strips are respectively inserted into the inner grooves of the two inwardly rolled edges until the two second protruding strips are fully inserted into the inner groove. Multiple threaded grooves and multiple mounting holes are aligned with each other. Multiple fixing bolts are obtained, and multiple fixing bolts pass through multiple mounting holes. Multiple fixing bolts are threadedly connected to multiple threaded grooves. The second C-shaped plate is difficult to detach between the first wing plate and the second wing plate. The insertion method keeps the first C-shaped plate and the second C-shaped plate between the web plate, the first wing plate and the second wing plate, reducing the number of fixing bolts used. The installation is simple, efficient and quick. Tightening all fixing bolts completes the fixing of the first C-shaped plate and the second C-shaped plate. During the application of H-beams, the support for tensile and compressive strength is increased, the overall strength of H-beams is improved and earthquake resistance is effectively enhanced. The installation is simple and the disassembly is easy, saving time and manpower and improving operational efficiency.

[0005] To further improve the design, the fixing bolt is an internal hex bolt with its head hidden inside the mounting hole. This provides effective protection for the fixing bolt within the mounting hole and reduces external contact.

[0006] Further improvements include a first rounded corner on the side of the first wing plate and a second rounded corner on the side of the second wing plate. The addition of the first and second rounded corners reduces the sharp right-angled edges of the H-beam's overall sides, improving protection and increasing safety.

[0007] To further improve the design, the inner rolled edge is provided with a third rounded corner, and the inner groove, the first convex strip, and the second convex strip are also provided with a third rounded corner. The third rounded corner not only improves protection but also increases the contact surface between the first convex strip, the second convex strip, and the inner groove.

[0008] To further improve the design, the web plate is welded with internal support members on its side. There are four support members, two of which are welded to the first wing plate and the other two are welded to the second wing plate. The four support members further improve the overall strength of the web plate, the first wing plate and the second wing plate, and prevent the web plate, the first wing plate and the second wing plate from breaking and separating under stress.

[0009] To further improve the design, the cross-section of the support member is an isosceles triangle, and the support member has a triangular inner hole. All four support members have triangular inner holes, which ensures overall strength while reducing overall weight.

[0010] The beneficial effects of this utility model are: The first C-shaped plate is inserted between the first and second wing plates. Two first protrusions enter the inner grooves of the two inwardly rolled edges until they are fully inserted. Multiple threaded grooves align with multiple mounting holes to obtain multiple fixing bolts. These bolts pass through the mounting holes and are threaded into the threaded grooves. The first C-shaped plate is positioned between the first and second wing plates and is difficult to detach. The second C-shaped plate is inserted between the first and second wing plates on the other side. Two second protrusions enter the inner grooves of the two inwardly rolled edges until they are fully inserted. Multiple threaded grooves align with multiple mounting holes to obtain multiple fixing bolts. The mounting holes are aligned with each other to obtain multiple fixing bolts. These bolts pass through the mounting holes and are threaded into the threaded grooves. The second C-shaped plate is difficult to detach between the first and second flanges. The insertion method keeps the first and second C-shaped plates between the web, the first flange, and the second flange, reducing the number of fixing bolts required. Installation is simple, efficient, and quick. Tightening all fixing bolts completes the fixing of the first and second C-shaped plates. During application, the H-beam increases its tensile and compressive strength, improves its overall strength, and effectively resists earthquakes. Installation is simple, disassembly is easy, saving time and manpower and improving operational efficiency.

[0011] The overall strength of the web, first wing plate and second wing plate is further improved by four support members to prevent the web, first wing plate and second wing plate from breaking and separating under stress. All four support members are provided with triangular inner holes to ensure overall strength while reducing overall weight. Attached Figure Description
