Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a high-strength lightweight steel grating. Background Technology

[0002] As a material used in industrial buildings, the strength and weight of steel grating are important indicators for measuring its performance. With the increasing requirements for material performance in industrial buildings, traditional steel gratings are heavy while meeting strength requirements, which increases the burden on the building structure and is not conducive to lightweighting and energy conservation. In recent years, some lightweight steel gratings have appeared on the market, but the degree of lightweighting is limited while ensuring strength, and cannot fully meet the needs of modern industrial buildings.

[0003] A search revealed Chinese patent publication number CN218091204U, which discloses a steel grating comprising a mounting frame and a grid plate. The grid plate includes several vertical bars and several horizontal bars. One side of the grid plate is hinged to the mounting frame. A receiving block is fixedly connected to the mounting frame, and the receiving block has several receiving grooves. The ends of several vertical bars are rotatably engaged in the receiving grooves. Locking components for locking the vertical bars are provided on the vertical bars and the receiving block. This application aims to improve the ease of use of the steel grating. However, in actual use, while the vertical bars and receiving blocks enhance ease of use, they do not adequately guarantee the lightweight and high strength of the steel grating, resulting in safety hazards in practical applications and hindering its large-scale promotion and application. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-strength lightweight steel grating, aiming to improve the defects of existing technologies that cannot adequately guarantee the lightweight and high strength of steel gratings, resulting in safety hazards in practical applications and making it difficult to promote and apply on a large scale.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength lightweight steel grating, comprising a mounting frame, wherein multiple load-bearing flat steels are fixedly connected to the front side of the inner wall of the mounting frame, and the bottom walls of the multiple load-bearing flat steels are provided with engaging grooves, and the top walls of the load-bearing flat steels are threadedly connected with multiple high-strength bolts, and the bottom of the load-bearing flat steels are provided with multiple transverse flat steels, the tops of the transverse flat steels are provided with multiple mounting grooves at equal intervals, the bottom ends of the multiple high-strength bolts respectively penetrate the interior of the corresponding load-bearing flat steels and are threadedly connected to the mounting grooves, the tops of the multiple transverse flat steels respectively engage with the corresponding engaging grooves, and an anti-compression mechanism is provided on the left side of the inner wall of the mounting frame.

[0006] The above technical solution enables multiple load-bearing flat steel bars and transverse flat steel bars to form a square grid structure through the connection of high-strength bolts, thereby achieving the lightweight effect of steel-chrome plates, reducing the burden on building structures, improving construction efficiency, and then optimizing the connection effect between load-bearing flat steel bars and transverse flat steel bars to improve load-bearing capacity, increase load-bearing area, and avoid potential safety hazards in practical applications.

[0007] As a further description of the above technical solution: The anti-compression mechanism includes a gel plate layer. The left side of the gel plate layer is fixedly connected to the left side of the inner wall of the mounting frame. An anti-compression layer is fixedly connected to the right side of the gel plate layer. An anti-compression plate is fixedly connected to the left side of the inner wall of the anti-compression layer. Multiple arc-shaped grooves are opened on the right side of the anti-compression plate. Protective pads are fixedly connected inside the arc-shaped grooves. Support strips are fixedly connected to the front and rear ends of the right side of the anti-compression plate.

[0008] The above technical solution improves the thermal insulation effect between the mounting frame and the steel grating by connecting the gel plate layer, reduces the impact of temperature changes at the connection point, and provides compressive protection for the outer wall of the steel grating by connecting the compressive layer, thus extending the service life of the steel grating.

[0009] As a further description of the above technical solution: The shape of each of the aforementioned load-bearing flat steel bars is trapezoidal, and the width of the upper base of the trapezoid is smaller than the width of the lower base.

[0010] The above technical solutions increase the load-bearing area and improve the load-bearing capacity.

[0011] As a further description of the above technical solution: The cross-sections of the multiple transverse flat steel bars are all rectangular, and the height of the rectangle is less than the height of the trapezoid of the supporting flat steel bar.

[0013] As a further description of the above technical solution: Multiple positioning holes are equidistantly provided on the front side of the multiple transverse flat steel bars, and multiple reinforcing ribs are slidably connected to the front side of the mounting bracket. The rear ends of the multiple reinforcing ribs respectively penetrate the interior of the bearing flat steel bar and engage with the positioning holes.

[0014] The above technical solution further improves the strength and stability of the overall structure through the connection of reinforcing ribs.

[0015] As a further description of the above technical solution: Multiple partition strips are fixedly connected to the middle right side of the pressure-resistant plate, and the partition strips are arranged at equal intervals.

[0016] The above technical solution enables pressure to be distributed through the connection of multiple separators.

[0017] As a further description of the above technical solution: The pressure-resistant mechanism also includes a buffer layer, the right side of which is fixedly connected to the right side of the inner wall of the mounting frame.

[0018] The above technical solution further improves the buffering effect by connecting the buffer layer.

[0019] As a further description of the above technical solution: Each of the high-strength bolts has a rubber ring fixedly connected to its center, and the high-strength bolts are arranged symmetrically at equal intervals.

[0020] The above technical solution reduces rotational damage to the top of the load-bearing flat steel caused by the high-strength bolts, thanks to the connection of the rubber ring.

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.

[0026] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a high-strength lightweight steel grating, including a mounting frame 1. Multiple load-bearing flat steels 3 are fixedly connected to the front inner wall of the mounting frame 1. Each load-bearing flat steel 3 has a locking groove 6 on its bottom wall. The locking groove 6 improves the connection stability between the horizontal flat steels 5 and the load-bearing flat steels 3. Multiple high-strength bolts 4 are threaded to the top wall of the load-bearing flat steel 3. Multiple horizontal flat steels 5 are provided at the bottom of the load-bearing flat steel 3. The connection of the horizontal flat steels 5 is achieved through the multiple high-strength bolts 4, ensuring that the preload can guarantee the connection effect of the steel grating. Multiple installation grooves 10 are equidistantly provided on the top of the horizontal flat steels 5. The bottom ends of the multiple high-strength bolts 4 penetrate the interior of the corresponding load-bearing flat steel 3 and are threaded to the installation grooves 10. Thus, with the multiple load-bearing flat steels 3 and multiple horizontal flat steels 5 forming a square grid structure, the burden on the building structure is reduced, and construction efficiency is improved. The tops of the multiple horizontal flat steels 5 are respectively engaged with the corresponding locking grooves 6. A pressure-resistant mechanism 2 is provided on the left side of the inner wall of the mounting frame 1. Specifically, by engaging multiple load-bearing flat steels 3 with transverse flat steels 5, a preliminary fixing effect can be achieved. By using multiple high-strength bolts 4 to penetrate the interior of the load-bearing flat steels 3 and threadedly connect them to the mounting grooves 10 at the top of the transverse flat steels 5, a square grid structure can be constructed, thereby achieving lightweighting, effectively reducing the burden on the building structure, and improving construction efficiency. Through the cross-sectional shapes of the load-bearing flat steels 3 and transverse flat steels 5, the load-bearing area of ​​the steel grating is further increased, thereby improving its load-bearing capacity, reducing the overall weight of the steel grating, and ensuring the stability and safety of the overall structure, making it easy to promote and apply on a large scale in a wider range.

[0027] Reference Figure 1 , Figure 3 and Figure 5 The anti-compression mechanism 2 includes a gel plate layer 201. The left side of the gel plate layer 201 is fixedly connected to the left side of the inner wall of the mounting frame 1, and the right side of the gel plate layer 201 is fixedly connected to an anti-compression layer 202. With the connection of the gel plate layer 201, the heat insulation effect of the mounting frame 1 can be improved, thereby achieving the effect of protecting the connection between the load-bearing flat steel 3 and the outer wall of the transverse flat steel 5. An anti-compression plate 203 is fixedly connected to the left side of the inner wall of the anti-compression layer 202. Multiple arc-shaped grooves 204 are opened on the right side of the anti-compression plate 203. Protective pads 205 are fixedly connected inside the arc-shaped grooves 204. Then, with the connection between the anti-compression plate 203 and multiple protective pads 205, the damage of external pressure to the steel grating can be reduced. Support bars 206 are fixedly connected to the front and rear ends of the right side of the anti-compression plate 203. Specifically, the connection of the gel plate layer 201 can improve the thermal insulation performance of the outer wall connection of the load-bearing flat steel 3 and the transverse flat steel connection 5. This improvement reduces the adverse effects of temperature changes on the connection, thereby improving the overall performance. With the assistance of the pressure-resistant layer 202, the connection of the pressure-resistant plate 203 and multiple protective pads 205 further enhances the protection of the outer wall of the steel plate, reducing the deformation and damage that external pressure may cause to the steel plate, thereby extending the service life of the steel plate.

[0028] Reference Figure 2 and Figure 4 The shape of each of the multiple load-bearing flat steels 3 is trapezoidal, and the width of the upper base of the trapezoid is smaller than the width of the lower base; the cross-section of each of the multiple transverse flat steels 5 is rectangular, and the height of the rectangle is smaller than the height of the trapezoid of the load-bearing flat steel 3; multiple positioning holes 8 are equally spaced on the front side of each of the multiple transverse flat steels 5; multiple reinforcing ribs 9 are slidably connected to the front side of each of the mounting brackets 1; the rear ends of the multiple reinforcing ribs 9 pass through the interior of the load-bearing flat steel 3 and engage with the positioning holes 8. Specifically, by setting the shape of multiple load-bearing flat steels 3 to trapezoidal with the upper base width being smaller than the lower base width, the load-bearing area of ​​the steel grating is increased, thereby improving its load-bearing capacity. By setting the cross-section of multiple transverse flat steels 5 to rectangular with the height of the rectangle being smaller than the trapezoidal height of the load-bearing flat steel 3, the overall weight of the steel grating is reduced. Furthermore, by using multiple reinforcing ribs 9, the strength and stability of the overall structure are further improved.

[0029] Reference Figure 2 , Figure 3 and Figure 5 Multiple partition strips 207 are fixedly connected to the middle right side of the pressure-resistant plate 203, and the multiple partition strips 207 are arranged at equal intervals; the pressure-resistant mechanism 2 also includes a buffer layer 208, and the right side of the buffer layer 208 is fixedly connected to the right side of the inner wall of the mounting frame 1; multiple high-strength bolts 4 are fixedly connected to the middle of the rubber rings 7, and the multiple high-strength bolts 4 are arranged at equal intervals symmetrically. Specifically, multiple separators 207 improve the effect of dispersing pressure, buffer layer 208 further increases the buffering effect inside the steel grating, and multiple rubber rings 7 reduce the rotational damage of the high-strength bolts 4 to the top of the bearing flat steel 3.

[0030] Working principle: By engaging multiple load-bearing flat steels 3 with transverse flat steels 5, a preliminary fixing effect is achieved. Subsequently, multiple high-strength bolts 4 penetrate the interior of the load-bearing flat steels 3 and are threadedly connected to the transverse flat steels 5, forming a square grid structure. This achieves lightweighting, reduces the structural load on the building, and improves construction efficiency. The cross-sectional shapes of the load-bearing flat steels 3 and transverse flat steels 5 increase the load-bearing area of ​​the steel grating, improve its load-bearing capacity, and reduce the overall weight of the steel grating, thereby ensuring the stability and safety of the overall structure and facilitating large-scale application. Furthermore, the connection of the gel plate layer 201 improves the heat insulation effect at the connection between the mounting frame 1 and the outer wall of the connection between the bearing flat steel 3 and the transverse flat steel 5, thereby reducing the impact of temperature changes on the use of the connection. At the same time, the connection of the pressure-resistant layer 202, and the connection between the pressure-resistant plate 203 and multiple protective pads 205, enhances the protection of the outer wall of the steel chrome plate, reducing the damage caused by external pressure and thus increasing the service life of the steel chrome plate.
