Abstract
Description
Technical Field
[0001] This utility model relates to steel structure technology, and more specifically, to steel beams for steel structures. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Steel structures are formed by splicing together components such as steel columns, steel beams, and steel trusses. Among them, steel beams are generally horizontally connected between adjacent steel columns. In actual production, C-shaped steel is usually used to make steel beams.
[0003] According to Chinese Patent No. CN219508985U, a steel structure beam is disclosed. Its key technical features are: it includes two structural beam bodies, which are arranged in a C-shape and are arranged opposite to each other. Each structural beam body is composed of a central vertical plate and horizontal plates on the upper and lower sides. The vertical plate has horizontal holes at equal intervals, and the horizontal plates have longitudinal holes at equal intervals. A connecting component is installed between the two structural beam bodies.
[0004] The above solution addresses the problem that the existing two C-shaped steel beams are only fixed together by bolts, resulting in low connection strength and poor stability. However, installing the connecting components requires opening many holes on the upper and lower ends of the structural beams, which can reduce the strength of the structural beams themselves and potentially shorten their service life.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide steel beams for steel structures.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel beam for steel structure, including two C-beams, the openings of the two C-beams are arranged opposite to each other, a plurality of circular holes for bolts to pass through are opened in the middle of the C-beams, and fasteners are detachably connected to the upper and lower sides of the two C-beams, the fasteners being used to align the top surfaces of the two C-beams and make them fit tightly together.
[0008] The present invention is further configured such that: the fastener includes two abutting blocks respectively mounted on two C-beams, and a threaded post for adjusting the spacing between the two abutting blocks passes through them.
[0009] The present invention is further configured such that: the abutting block includes a connecting part and an abutting part fixed to one end of the connecting part, the abutting part is perpendicular to the connecting part, the threaded post is threadedly connected to the connecting part, and the end of the abutting part away from the connecting part is provided with an anti-disengagement hook for preventing the abutting part from disengaging.
[0010] The present invention is further configured such that a rubber pad is provided on the side wall of the contact part used to contact the C-beam.
[0011] The present invention is further provided with rough surfaces on the side walls of the two C-beams facing each other to increase their maximum static friction.
[0012] The present invention is further configured such that: a shear plate is fixed to the connecting part of one of the abutting blocks, and a groove for the shear plate to be embedded is provided on the connecting part of the other abutting block.
[0013] The present invention is further configured such that hexagonal grooves are provided at both ends of the threaded column.
[0014] The present invention is further configured such that: the shear plate is made of YG8 hard alloy, and the outer surface of the C-beam is coated with anti-rust paint.
[0015] In summary, this utility model has the following beneficial effects: When installing two C-beams, bolts are first used to fix the two C-beams. Then, the required number of fasteners can be installed on the two C-beams according to the actual use scenario. The fasteners ensure that the top and bottom surfaces of the two C-beams are aligned while also ensuring a tight fit between the two C-beams. This effectively restricts the two interlocking C-beams in both the horizontal and vertical directions, thereby improving the connection strength of the two C-beams. This solution eliminates the need to drill holes in the top and bottom surfaces of the C-beams, which can significantly improve the strength of the top and bottom surfaces of the C-beams. It also reduces the drilling time in the top and bottom surfaces of the C-beams, and simplifies the processing of the C-beams, resulting in higher production efficiency. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] Steel beams for steel structures, such as Figure 1As shown, the device includes two C-beams 1 with their openings facing away from each other. Several circular holes 2 for bolts to pass through are provided in the middle of each C-beam 1. Fasteners are detachably connected to the two C-beams 1, aligning their top surfaces and ensuring they are tightly fitted together. When installing the two C-beams 1, bolts are first used to fix them in place. Then, the required number of fasteners can be installed on the two C-beams 1 according to the actual application scenario. The fasteners ensure that the top and bottom surfaces of the two C-beams 1 are aligned while also ensuring a tight fit, effectively restricting the two C-beams 1 in both the horizontal and vertical directions, thereby improving the connection strength. This design eliminates the need for drilling holes in the top and bottom surfaces of the C-beams 1, significantly improving their strength and reducing drilling time. It also simplifies the manufacturing process of the C-beams 1, resulting in higher production efficiency.
[0021] like Figure 2As shown, the fastener includes two clamping blocks respectively mounted on two C-beams 1. A threaded post 3 for adjusting the spacing between the two clamping blocks passes through them. The two ends of the threaded post 3 have symmetrically arranged threads. During the installation of the fastener on the two C-beams 1, the symmetrically arranged threads allow the two clamping blocks to move towards each other by rotating one end of the threaded post 3. This simplifies the installation process by requiring only one rotation of the threaded post 3 to achieve a tight fit between the two clamping blocks and the C-beams 1, making the fastener installation process convenient and easy to operate. Simultaneously, the threaded post 3 connects... The two clamping blocks, due to the self-locking effect of the threaded connection, prevent the threaded post 3 from rotating after rotation, thus preventing the two clamping blocks from moving away from each other. This allows the fastener to effectively restrain the two C-beams 1, improving the connection strength of the two C-beams 1. The clamping block includes a connecting part 4 and an abutting part 5 fixed to one end of the connecting part 4. The abutting part 5 is perpendicular to the connecting part 4. The threaded post 3 is threadedly connected to the connecting part 4. The end of the abutting part 5 away from the connecting part 4 is provided with an anti-disengagement hook 6 to prevent the abutting part 5 from disengaging. During the installation of the fastener... The anti-disengagement hook 6 needs to be secured to the C-beam 1. During the final tightening of the threaded post 3, the anti-disengagement hook 6 prevents the contact part 5 from detaching from the C-beam 1. This eliminates the need for the user to hold the contact part 5 during the final tightening process. The side wall of the contact part 5 that contacts the C-beam 1 is equipped with a rubber pad 7. During the tightening process, the rubber pad 7 contacts the C-beam 1 and is compressed and deformed under external force. The rubber pad 7 generates internal stress due to its material properties, allowing it to recover its original shape. This ensures that the rubber pad 7 effectively fills the gap between the C-beam 1 and the C-beam 1. The gap between the contact parts 5 allows the contact parts 5 to better abut the two C-beams 1. In addition, during the use of the steel beams, external vibrations will be transmitted to the C-beams 1, and the rubber pad 7 can effectively absorb the vibrations, thereby reducing the possibility of rigid collision between the contact parts 5 and the C-beams 1. The side walls of the two C-beams 1 facing each other are provided with rough surfaces to increase their maximum static friction. The rough surface design makes the static friction between the two C-beams 1 larger after they are assembled with bolts, making it less likely for them to slide relative to each other, which is beneficial for the subsequent installation of fasteners.
[0022] like Figure 1 and Figure 2As shown, a shear plate 8 is fixed to the connecting part 4 of one of the clamping blocks, and a groove for the shear plate 8 to be embedded in the connecting part 4 of the other clamping block. Shear stress is easily generated at the splice of the two C-beams 1. The shear plate 8 can better withstand the shear stress generated at the splice, thereby improving the shear resistance of the fastener itself. Hexagonal grooves 9 are provided at both ends of the threaded column 3. The hexagonal grooves 9 make it easy to rotate the threaded column 3 with an Allen wrench, which facilitates the operation of the threaded column 3. The shear plate 8 is made of YG8 cemented carbide. The outer surface of the C-beam 1 is coated with anti-rust paint. The high shear strength of YG8 cemented carbide can effectively ensure the shear resistance of the shear plate 8. The anti-rust paint coating makes the outer surface of the C-beam 1 less likely to come into contact with air, thus making the outer surface of the C-beam 1 less likely to undergo oxidation reaction with moisture and oxygen in the air, which can improve the service life of the C-beam 1.
