Description

Technical Field

[0001] This utility model relates to the field of corner protection technology, and in particular to a corner protection net. Background Technology

[0002] Corner guards are protective devices installed at the corners of buildings (such as interior and exterior corners, stairwell corners, and column corners). They are typically made of metal (such as stainless steel or galvanized steel), plastic, or rubber, and come in various forms, including mesh, strips, or angles. They are attached to the right angle or protruding part of the corner using fasteners (such as screws or adhesive), forming a physical protective layer. Corners are protruding parts of buildings and are easily subjected to impacts during daily activities (such as furniture moving, pedestrians falling, children playing, and vehicle scratches). Over time, this can lead to wall damage, paint peeling, cracks, and even affect structural stability. Corner guards can buffer impacts, extend the lifespan of corner guards, and reduce maintenance costs.

[0003] In existing technologies, some corner protection nets adopt a spliced ​​design, and generally use plastic corner protectors or wire mesh corner protectors. The nets themselves are weak and cannot withstand strong impacts. They are prone to local loosening or even breakage due to uneven force distribution, and cannot achieve efficient force transmission and dispersion. In addition, the contact area of ​​the nets with the wall surface is small, which makes it easy for the nets to fall off completely. Therefore, in order to address the above shortcomings, a new type of corner protection net is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a corner protection net, which aims to improve the problem that some corner protection nets in the prior art are prone to breakage and fall off as a whole, resulting in a reduced service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corner guardrail includes a metal right-angle steel. The bottom left and right ends of the metal right-angle steel are provided with guardrail mechanisms. Each of the two guardrail mechanisms includes a side steel. The top ends of the two side steels are respectively located at the bottom left and right ends of the metal right-angle steel. The interior of each of the side steels is provided with a round hole. The interior of the left and right ends of the metal right-angle steel is provided with multiple trapezoidal openings.

[0007] As a further description of the above technical solution:

[0008] Both of the aforementioned protective netting mechanisms also include side steel 2. The top ends of the two side steel 2 are respectively located at the bottom left and right ends of the metal right angle steel. The side steel 2 has a round hole 2 inside. The left and right ends of the metal right angle steel have multiple trapezoidal openings 2 inside. A plastic strip is clamped on the top side of the metal right angle steel.

[0009] As a further description of the above technical solution:

[0010] Both of the aforementioned protective netting mechanisms also include side steel three, the tops of the two side steel three are respectively located at the bottom left and right ends of the metal right angle steel, the side steel three has a circular hole three inside, and the left and right ends of the metal right angle steel have multiple triangular openings inside;

[0011] As a further description of the above technical solution:

[0012] Both of the aforementioned protective netting mechanisms also include side steel fours, the top ends of the two side steel fours are respectively located at the bottom left and right ends of the metal right angle steel, the side steel fours have a circular hole four inside, and the left and right ends of the metal right angle steel each have multiple semi-circular openings inside.

[0013] As a further description of the above technical solution:

[0014] The side steel is trapezoidal in shape.

[0015] As a further description of the above technical solution:

[0016] The side steel plate 2 is trapezoidal in shape.

[0019] As a further description of the above technical solution:

[0020] The shape of the side steel four is semi-circular.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, any one of the side steels (one, two, three, and four) is integrally forged with a right-angled metal steel shape, enabling efficient force transmission and dispersion when subjected to stress. This effectively prevents localized loosening or even breakage caused by uneven stress. Simultaneously, the outward-curving design of the side steels increases the contact area between the protective netting and the wall surface. The round holes in the side steels allow cement to pass through, making the netting more secure and preventing it from falling off entirely. This significantly improves the structural stability and service life of the protective netting, better protecting the corners of the walls. Attached Figure Description

[0033] 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.

[0034] Example 1

[0035] Reference Figure 1This utility model provides an embodiment of a corner protection net, comprising a metal right-angle steel bar 1. The metal right-angle steel bar 1 is made of steel and is right-angled, providing stable support for the entire corner protection net. A plastic strip 2 is fastened to the top side of the metal right-angle steel bar 1. The fastening method utilizes the elasticity of the plastic strip's opening to ensure a firm connection between the plastic strip 2 and the metal right-angle steel bar 1. The plastic strip 2 can prevent the sharp edges of the metal right-angle steel bar 1 from deforming after a severe impact to the corner. The plastic strip 2 is made of soft plastic, which can alleviate the impact and also rebound to its original state. Protective net mechanisms 3 are provided at both the left and right ends of the bottom of the metal right-angle steel bar 1. The protective net mechanisms 3 at the left and right ends are symmetrically distributed, forming protection for the corner from both sides. Both protective net mechanisms 3 include side steel bars 311. The side steel bars 311 are trapezoidal in shape. The trapezoidal structure of the side steel bars 311 makes them more stable under stress and can better disperse external forces. The tops of the two side steel bars 311 are respectively set at the bottom left and right ends of the metal right angle steel 1. They are integrally forged to form a single unit with the metal right angle steel 1, enhancing the structural continuity. Several of the side steel bars 311 have round holes 312 inside. These holes not only reduce the weight of the side steel bars 311 but also facilitate subsequent installation and fixing. Multiple trapezoidal openings 313 are formed inside the left and right ends of the metal right angle steel 1. These trapezoidal openings 313 correspond to the shape of the side steel bars 311, ensuring the strength of the metal right angle steel 1 while increasing the contact area between the protective netting and the wall.

[0036] Example 2

[0037] Reference Figure 2 Both protective netting mechanisms 3 also include side steel plates 321. These side steel plates 321 are trapezoidal in shape, and their trapezoidal structure helps improve the overall stability of the protective netting mechanism 3. Furthermore, the entire corner protective netting is integrally forged, eliminating the need for additional connection processes between components, resulting in a more robust structure. The tops of the two side steel plates 321 are respectively located at the bottom left and right ends of the metal right-angle steel 1. Through integral forging, the side steel plates 321 and the metal right-angle steel 1 form a stable overall structure. Because it is integrally forged, the connection between the two is tight, effectively transmitting and dispersing external forces. The side steel 2 321 has a circular hole 2 322 inside. The circular hole 2 322 can reduce the overall weight while ensuring the structural strength of the side steel 2 321. It also provides convenience for possible subsequent installation or other functional expansion. The left and right ends of the metal right angle steel 1 have multiple trapezoidal openings 2 323 inside. The design of the trapezoidal openings 2 323 echoes the structure of the side steel 2 321. It will not weaken the strength of the metal right angle steel 1 too much, and can further optimize the stress situation of the overall structure. Moreover, because it is integrally forged, the edges of these openings are smoother, avoiding the problem of stress concentration.

[0038] Example 3

[0039] Reference Figure 3 Both protective netting mechanisms 3 include side steel plates 331. These side steel plates 331 are triangular in shape, and their stable triangular structure provides reliable support for the protective netting mechanism 3, effectively resisting external impacts. Furthermore, the entire corner protective netting is integrally forged, eliminating seams and significantly improving structural stability. The tops of the two side steel plates 331 are respectively positioned at the bottom left and right ends of the metal right-angle steel 1. Through integral forging, the side steel plates 331 provide symmetrical support to the metal right-angle steel 1 from both sides. Because they are integrally forged, the connection between the side steel plates 331 and the metal right-angle steel 1 has high strength, allowing for even force distribution throughout the structure. The side steel plates 331 have internal circular holes 332. The design of these circular holes 332 does not compromise the overall stability of the side steel plates 331, reduces structural weight to some extent, and facilitates subsequent installation and fixing operations. Multiple triangular openings 333 are provided inside both ends of the metal right angle steel 1. The triangular openings 333 are adapted to the shape of the side steel 331. While ensuring the structural strength of the metal right angle steel 1, the overall stress distribution is further optimized. Moreover, due to the integral forging, the edges of the triangular openings 333 are smooth and flat, avoiding the occurrence of stress concentration.

[0040] Example 4

[0041] Reference Figure 4 Both protective netting mechanisms 3 also include side steel plates 341. These side steel plates 341 are semi-circular in shape and have an arc-shaped structure, which provides a buffering effect when subjected to external impact, reducing direct impact on the corners of the walls. Furthermore, the entire protective netting is manufactured using a one-piece forging process, without any splicing marks, resulting in stronger structural stability. The tops of the two side steel plates 341 are respectively located at the bottom left and right ends of the metal right-angle steel 1. This symmetrical layout allows the protective netting mechanism 3 to evenly distribute external forces from both sides. Due to the one-piece forging process, the connection between the side steel plates 341 and the metal right-angle steel 1 has high strength, reducing the possibility of loosening or breakage. The side steel plates 341 have internal circular holes 342. These holes reduce the overall weight of the side steel plates 341 and facilitate the installation and fixing of the protective netting without affecting its structural strength. Multiple semi-circular openings 343 are provided inside both the left and right ends of the metal right angle steel 1. The shape of the semi-circular openings 343 corresponds to that of the side steel 4 341. While ensuring the supporting performance of the metal right angle steel 1, the overall stress structure is further optimized. Moreover, due to the integral forging and pressing, the edges of the semi-circular openings 343 are smooth, which avoids stress concentration and extends the service life of the protective net.

[0042] Working principle:

[0043] The working principle of Embodiment 1 is as follows: the plastic strip 2 on the metal right-angle steel 1 prevents the sharp edges of the metal right-angle steel 1 from deforming after a severe impact. The plastic strip 2 is made of soft plastic, which can alleviate the impact and also rebound to its original state. After installation, the side steel 311 utilizes the mechanical properties of the trapezoidal structure to disperse the external force along the inclined side. The integral forging ensures efficient and uniform force transmission. The round hole 312 reduces weight without interfering with the force dispersion path. The trapezoidal opening 313 echoes the shape of the side steel 311, further optimizing the overall force distribution and forming all-round protection.

[0044] The working principle of Example 2 is that the side steel 321 relies on the stability of the trapezoidal structure to resist external forces from multiple directions, and the integral forging ensures the direct transmission of force and avoids local damage. The round hole 322 reduces weight and reserves deformation space. It buffers external forces through small deformation. The trapezoidal opening 323 echoes the structure of the side steel 321, ensuring the support strength while guiding the transmission of force and improving the stability under stress.

[0045] The working principle of Example 3 is that the side steel 331, with its triangular stability, can withstand a large impact. It is integrally forged to form a solid whole, and the external force is evenly distributed to all parts of the metal right-angle steel 1. The round hole 332 reduces weight without compromising stability, and the triangular opening 333 is adapted to the shape of the side steel 331 to help disperse stress and enhance the stability of the structure under stress.

[0046] In Example 4, the side steel 341 utilizes an arc-shaped structure to disperse the impact force along the arc, while absorbing energy through slight deformation, reducing the force transmitted to the corner. One-piece forging ensures uniform stress transmission, avoiding localized concentrated damage. The circular hole 342 provides space for arc-shaped deformation to enhance cushioning, and the semi-circular opening 343 echoes the shape of the side steel 341, ensuring support performance and guiding force transmission, thus optimizing the cushioning effect.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
