Description

Technical Field

[0001] This utility model relates to the field of building components technology, specifically to an H-shaped light steel component for light steel prefabricated buildings. Background Technology

[0002] Prefabricated light steel structures are widely used in residential and public buildings due to their advantages of fast construction speed, environmental friendliness, energy saving, and high space utilization. H-shaped light steel components, as the core load-bearing parts of prefabricated light steel structures, are mainly used in frame structures such as beams and columns, and their performance directly affects the overall safety and stability of the building. However, traditional H-shaped light steel components suffer from insufficient strength at the connection between the web and flange plates during use, making them prone to deformation and cracking under long-term loads, affecting the stability and service life of the building structure. To ensure the lifespan of traditional H-shaped light steel components, some steel components are fitted with reinforcing parts. Traditionally, these reinforcing parts are assembled onto the steel components using welding or threaded connections, resulting in a cumbersome, time-consuming, and labor-intensive installation process, which fails to meet the needs of efficient construction in prefabricated light steel structures. Therefore, developing a high-strength, easy-to-install H-shaped light steel component is key to solving the pain points of existing technologies. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an H-shaped light steel component for prefabricated light steel buildings. By setting a reinforcing component at the connection between the web and the flange, the main body of the reinforcing component is a reinforcing block with a right-angled triangular cross-section. The reinforcing block abuts between the web and the flange, which can effectively enhance the strength of the H-shaped light steel component and prevent deformation. Moreover, the reinforcing block is easy to assemble and disassemble, has good stability, and is convenient to use, thus solving the problems of unsatisfactory strength and easy deformation of current H-shaped light steel components.

[0004] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A lightweight steel H-shaped prefabricated building component includes a steel component body, which is composed of a web and flanges integrally formed on both sides of the web. Reinforcing components are provided at the connection points between the web and the flanges to enhance the strength of the steel component body. Each reinforcing component includes a reinforcing block with a right-angled triangular cross-section. The right-angled sides of the reinforcing block are respectively attached to the web and the flange. An upper reinforcing plate protrudes from the side of the reinforcing block closest to the flange, and a lower reinforcing plate protrudes from the side closest to the web. A fixing module is provided in a slot on one side of the upper reinforcing plate, and the fixing module is connected and fixed to the corresponding flange, enabling quick assembly and fixing of the reinforcing components on the steel component body.

[0005] Furthermore, a boss protrudes from the center of the web plate, and positioning grooves are formed on both sides of the boss. One side of the reinforcing block and the lower reinforcing plate are adapted to the corresponding positioning grooves, and one side of the lower reinforcing plate abuts against the boss.

[0006] Furthermore, the positioning groove of the web plate is fixedly connected with equidistantly distributed round rods along the length of the web plate, and the ends of the round rods are coaxially fixed with screws. The lower reinforcing plate is provided with round holes that are adapted to the round rods at the corresponding positions, and the screws are threaded with a first clamping nut, one side of which abuts against the lower reinforcing plate.

[0007] Furthermore, the reinforcing block has a hollow cavity with a right-angled triangular cross-section, and multiple reinforcing ribs are fixedly connected to the hollow cavity of the reinforcing block, the reinforcing ribs being arranged along the length direction of the reinforcing block.

[0008] Furthermore, the flange plate is fixedly connected to the side near the web plate with equidistant T-shaped guide rails, and the reinforcing block has equidistant T-shaped grooves on one side, which are adapted to the T-shaped guide rails.

[0009] Furthermore, the fixing module includes a fixing plate, a plug rod fixedly connected to one side of the fixing plate, and a threaded rod coaxially fixed to one end of the plug rod. A second clamping nut is threadedly connected to the threaded rod. A hidden groove is provided on one side of the flange plate, and the upper reinforcing plate and the flange plate are provided with insertion holes adapted to the plug rod at the corresponding hidden grooves. The plug rod is inserted into the insertion holes, and the second clamping nut is threadedly connected to the threaded rod with one side abutting against the flange plate. The second clamping nut is located in the hidden groove.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides an H-shaped light steel component for prefabricated light steel buildings, which has the following beneficial effects: 1. This utility model, by setting a reinforcing component at the connection between the web and the flange, has a core component that is a reinforcing block with a right-angled triangular cross-section. The right-angled triangular structure itself has extremely strong resistance to deformation. Its two right-angled sides are closely attached to the web and the flange respectively, which can effectively disperse the stress generated by the component when bearing load, and avoid the deformation and cracking problems at the connection between the web and the flange caused by stress concentration. At the same time, the reinforcing block has a hollow cavity with a right-angled triangular cross-section inside, and multiple reinforcing ribs are fixedly connected in the hollow cavity along the length of the reinforcing block. While reducing the self-weight of the component and reducing material costs, it further enhances the overall structural strength of the reinforcing block, thereby improving the load-bearing capacity and resistance to deformation of the entire steel component. Furthermore, one side of the lower reinforcing plate abuts against the boss, which plays a limiting role. This method provides a strong guarantee for the overall safety and stability of light steel prefabricated buildings and effectively extends the service life of the building.

[0011] 2. This utility model, by setting T-shaped guide rails and round rods, enables the reinforcing block to be accurately assembled into the positioning groove of the web plate. By setting a fixing module, the reinforcing block and the upper reinforcing plate can be quickly assembled into the flange plate. The assembly is convenient and easy to use on site.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, an embodiment of the present invention proposes an H-shaped light steel component for prefabricated light steel buildings, including a steel component body 1. The steel component body 1 is composed of a web 3 and flange plates 6 integrally formed on both sides of the web 3. Reinforcing components 2 for strengthening the steel component body 1 are provided at the connection between the web 3 and the flange plates 6. The reinforcing components 2 include reinforcing blocks 201 with right-angled triangular cross sections. The right-angled sides of the reinforcing blocks 201 are respectively attached to the web 3 and the flange plates 6. An upper reinforcing plate 207 is provided on the side of the reinforcing blocks 201 near the flange plate 6, and a lower reinforcing plate 203 is provided on the side near the web 3. A fixing module 208 is provided at the hollow groove 206 on one side of the upper reinforcing plate 207. The fixing module 208 is connected and fixed to the corresponding flange plate 6, realizing the quick assembly and fixing of the reinforcing components 2 on the steel component body 1.

[0016] It should be noted that the reinforcing block 201, with a right-angled triangular cross-section, utilizes the mechanical properties of the triangular structure, namely "strong stability and outstanding shear and compressive strength." Through the two right-angled sides, it is closely attached to the web plate 3 and the flange plate 6, transforming the longitudinal and transverse loads borne by the component into dispersed stress within the reinforcing block 201, thus avoiding stress concentration that could damage the connection. The upper reinforcing plate 207 and the lower reinforcing plate 203, as extensions of the reinforcing block 201, not only increase the contact area between the reinforcing block 201 and the steel component body 1 (further improving the force transmission efficiency), but also provide a space for fixing the hollow groove 206 of the upper reinforcing plate 207. Together with the fixing module 208, it achieves "precise alignment + rapid locking," eliminating the need for high-temperature operations or complex threaded connections required by traditional welding, thus meeting the core requirement of "efficient construction" in light steel prefabricated buildings.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, a boss 4 protrudes from the center of the web 3, and positioning grooves 9 are formed on both sides of the boss 4. One side of the reinforcing block 201 and the lower reinforcing plate 203 are adapted to the corresponding positioning grooves 9, and one side of the lower reinforcing plate 203 abuts against the boss 4.

[0018] It should be noted that the boss 4 at the center of the web 3 not only enhances the longitudinal stiffness of the web 3 (reducing the bending deformation of the web 3 under load), but also forms a "rigid limiting" structure through the design of the lower reinforcing plate 203 abutting against the boss 4. When the component is under load, if the reinforcing block 201 tends to move towards the center of the web 3, the boss 4 will generate a reverse supporting force on the lower reinforcing plate 203, preventing the reinforcing block 201 from displacing, ensuring that the reinforcing block 201 is always in the "optimal stress position" and continuously plays a reinforcing role at the connection.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the positioning groove 9 of the web plate 3 is fixedly connected with equidistantly distributed round rods 5 along the length direction of the web plate 3, and the ends of the round rods 5 are coaxially fixed with screws 10. The lower reinforcing plate 203 is provided with round holes 204 that are adapted to the round rods 5 at the corresponding positions of the round rods 5, and the screws 10 are threaded with a first clamping nut 205, one side of the first clamping nut 205 abutting against the lower reinforcing plate 203.

[0020] It should be noted that during the assembly of the reinforcing block 201, the lower reinforcing plate 203 is fitted onto the round rod 5 through the round hole 204 to achieve precise positioning. Then, the first clamping nut 205 is threaded onto the screw 10. By rotating the first clamping nut 205, one side of it abuts against the lower reinforcing plate 203, thereby achieving the clamping and fixing of the lower reinforcing plate 203. The round rod 5 and the screw 10 can achieve the limiting function during the assembly of the reinforcing block 201, and also achieve its fixing. The assembly accuracy is high and the use effect is good.

[0021] like Figure 3 As shown, in some embodiments, the reinforcing block 201 has a hollow cavity with a right-angled triangular cross section, and multiple reinforcing ribs 202 are fixedly connected to the hollow cavity of the reinforcing block 201. The reinforcing ribs 202 are arranged along the length direction of the reinforcing block 201.

[0022] It should be noted that the reinforcing ribs 202 can disperse the stress on the reinforcing block 201, increase the overall strength of the reinforcing block 201, and make it less prone to deformation.

[0023] like Figure 2 and Figure 4 As shown, in some embodiments, the flange plate 6 is fixedly connected to the side of the web plate 3 with T-shaped guide rails 8 distributed at equal intervals, and the side of the reinforcing block 201 is provided with T-shaped grooves 209 distributed at equal intervals, the T-shaped grooves 209 being adapted to the T-shaped guide rails 8.

[0024] It should be noted that the T-slot 209 can slide along the length of the T-rail 8 to provide "linear guidance" for the reinforcing block 201, ensuring that the reinforcing block 201 can be quickly and accurately positioned along the height of the flange plate 6 (without needing to repeatedly adjust the position, thus improving assembly efficiency).

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, the fixing module 208 includes a fixing plate 2081, a plug rod 2082 fixedly connected to one side of the fixing plate 2081, and a threaded rod 2083 coaxially fixed to one end of the plug rod 2082. A second clamping nut 2084 is threadedly connected to the threaded rod 2083. A hidden groove 7 is provided on one side of the flange plate 6. The upper reinforcing plate 207 and the flange plate 6 are provided with insertion holes 11 that are adapted to the plug rod 2082 at the corresponding hidden groove 7. The plug rod 2082 is inserted into the insertion hole 11. The second clamping nut 2084 is threadedly connected to the threaded rod 2083 and one side of it abuts against the flange plate 6. The second clamping nut 2084 is located in the hidden groove 7.

[0026] It should be noted that, firstly, after the insertion rod 2082 of the fixing module 208 is inserted into the insertion hole 11 of the upper reinforcing plate 207 and the flange plate 6, a "lateral through-type" connection is formed, mechanically locking the upper reinforcing plate 207 and the flange plate 6 (limiting the relative displacement between the two); while the threaded rod 2083 and the second clamping nut 2084 are threadedly engaged, and the fixing plate 2081, the upper reinforcing plate 207, and the flange plate 6 are tightly pressed together by axial pressure, eliminating the gaps between the three and ensuring efficient load transfer; secondly, the flange plate 6 The concealed groove 7 design completely houses the second clamping nut 2084, which on the one hand prevents the nut from being exposed to rain and dust (extending its service life), and on the other hand keeps the surface of the flange plate 6 flat (not affecting subsequent building decoration construction, such as wall installation and pipeline layout). In addition, the setting of the fixing plate 2081 expands the area of ​​the nut pressure, preventing local compression deformation of the flange plate 6 when the nut is tightened, and allows for large-area locking and fixing of the upper reinforcing plate 207 on the flange plate 6, with good locking effect.

[0027] The working principle and usage steps of this utility model are as follows: The operator holds the reinforcing component 2, aligning the T-shaped groove 209 on one side of the reinforcing block 201 with the T-shaped guide rail 8. Then, the operator slowly slides the reinforcing component 2 along the length of the T-shaped guide rail 8 until one side of the reinforcing block 201 and the lower reinforcing plate 203 fit into the positioning grooves 9 formed on both sides of the boss 4 on the web plate 3, and one side of the lower reinforcing plate 203 abuts against the boss 4, completing the initial positioning of the reinforcing component 2. During this process, the circular hole 204 is aligned with the circular rod 5, and the circular rod 5 is inserted into the circular hole 204 until the screw 10, which is coaxially fixed at the end of the circular rod 5, is fully exposed. Then, the first clamping nut 205 is taken and threaded onto the screw 10. The first clamping nut 205 is rotated clockwise using a wrench until the first clamping nut 205... One side of the upper reinforcing plate 207 is tightly abutted against the lower reinforcing plate 203 to fix the lower reinforcing plate 203, thereby completing the fixation of the lower part of the reinforcing component 2. Then, the insertion rod 2082 on one side of the fixing plate 2081 in the fixing module 208 is aligned with the insertion hole 11, and then the insertion rod 2082 is slowly inserted until the threaded rod 2083, which is coaxially fixed at one end of the insertion rod 2082, is fully inserted into the hidden groove 7, and the fixing plate 2081 is tightly attached to the upper reinforcing plate 207. The second clamping nut 2084 is taken out and threaded onto the threaded rod 2083. The second clamping nut 2084 is rotated clockwise with a wrench so that one side of the second clamping nut 2084 is tightly abutted against the flange plate 6, thus completing the fixation of the upper reinforcing plate 207. At this point, the assembly and fixation of the reinforcing component 2 on the steel component body 1 is completely completed.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
