Description

Technical Field

[0001] This utility model belongs to the field of invisible protective net installation technology, specifically relating to an invisible protective net profile structure. Background Technology

[0002] With the development of the modern construction industry, invisible protective netting, as a building protection device that combines safety and aesthetics, has been widely used in residential and commercial buildings. Its main function is to provide safety protection for buildings by fixing the protective netting wires through a profile structure, while minimizing the impact on the building's appearance. However, existing invisible protective netting profile structures have many technical defects in practical applications, affecting the safety, durability, and ease of installation of the protective netting, making it difficult to meet the high requirements of modern buildings for protective devices.

[0003] Currently, protective netting profiles primarily rely on screws for support. When these screws loosen or fall off due to rust or oxidation, the netting loses its support, posing a significant safety hazard. The profiles are secured with single-layer reinforcing ribs; under significant impact, these screws are prone to tilting and deformation, causing the netting to collapse and become unable to withstand external forces. The side covers are fixed by drilling through them with self-tapping screws, leaving exposed holes and protruding screw heads. This not only affects the product's appearance but also only serves to conceal imperfections, failing to improve the netting's performance. When fixing standard guide rails, expansion bolts are required. Drilling these holes can cause friction between the drill bit and the guide rail, damaging it and hindering installation, thus reducing work efficiency. Exposed screws, constantly exposed to the environment, are susceptible to wind, sun, rain, and moisture, accelerating rust and oxidation and shortening the netting's lifespan.

[0004] In view of this, we propose an invisible protective net profile structure to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems in the prior art, such as insufficient support of invisible protective net profiles leading to safety hazards, weak impact resistance, poor aesthetics, inconvenient installation and easy damage to guide rails, easy aging and short lifespan of screws, unstable fixing of steel wires, and lack of safety redundancy design.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A type of invisible protective netting profile structure, comprising:

[0008] The profile guide rail has rubber pad screws arranged in an orderly manner to cooperate with the installation and support of the protective net steel wire. The top plate of the profile guide rail has straight grooves at equal intervals between the inlet and outlet positions of the protective net steel wire, and the top plate of the profile guide rail has openings at equal intervals that communicate with the straight grooves.

[0009] The side cover is fixed to the profile guide rail by a snap-fit ​​mechanism;

[0010] After the side cover is placed on the profile guide rail, the protective wire mesh and rubber gasket screws are sealed in the profile cavity formed by the profile guide rail and the side cover.

[0011] The profile guide rail is equipped with a thickened reinforcing rib A and two raised reinforcing ribs B located symmetrically arranged in the profile cavity of the profile guide rail. When the rubber pad screw is installed, it is drilled through the reinforcing rib A and then limited and connected between the two raised reinforcing ribs B to form a support for the end of the rubber pad screw.

[0012] The profile guide rail is designed with double-layer reinforcement (a thickened outer reinforcement A and two symmetrically arranged inner reinforcements B). After the rubber pad screw is installed, it penetrates the first reinforcement (reinforcement A) and then gets into the two small raised reinforcements (reinforcement B) to form support for the end of the rubber pad screw.

[0013] Preferably, the outer side of the top plate and the outer side of the bottom plate of the profile guide rail are provided with locking positions A and B respectively, and the inner side of the top plate and the inner side of the bottom plate of the side cover are provided with locking strips A and B that are fastened together with locking positions A and B respectively.

[0014] Preferably, when fixing the profile guide rail, the straight groove and opening provide operating space for the mounting screws that pass through the profile guide rail, so that the drill bit can drive the screws at an angle or straight on the profile guide rail.

[0015] As a preferred embodiment, after the side cover is fitted with the profile guide rail, the side cover covers the opening and exposes the straight groove. When the rubber pad screws become loose and fall off, the closed cavity formed by the top plate of the profile guide rail and the side cover provides secondary restraint for the protective net wires, so that the protective net wires will not directly detach from the profile due to the rubber pad screws falling off, thus providing secondary support for the protective net.

[0016] Preferably, the rubber-coated screw includes a screw body and an I-shaped rubber washer fitted onto the screw body. The I-shaped rubber washer is used to cooperate with the installation of the protective net wire.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] (1) The invisible protective net profile structure, through the "I"-shaped structure formed by the double-layer reinforcing ribs and rubber pad screws, can disperse the shear force and torque on the rubber pad screws, reduce the degree of tilting deformation of the rubber pad screws, and limit the wrapping of the steel wire by the rubber pad screws to prevent the steel wire from shifting and slipping, thereby improving the stability of the fixation. When the rubber pad screws loosen, the top plate of the profile guide rail and the straight groove form a limiting structure to prevent the rubber pad screws from falling off. In addition, the secondary support of the aluminum alloy profile creates a "double insurance" protection mechanism. The closed cavity formed by the side cover and the profile guide rail isolates the rubber pad screws from the external environment, slows down the rusting and oxidation rate of the rubber pad screws and aluminum alloy profiles, and improves the aging problem of the steel wires due to ultraviolet radiation. The overall tensile strength is improved, and it can withstand greater impact force, making it especially suitable for humid, coastal and high-frequency vibration scenarios.

[0019] (2) The snap-on side cover design requires no tools; it can be fixed simply by pressing, significantly reducing installation time compared to traditional self-tapping screws. This offers significant advantages for high-altitude operations or batch construction. Disassembly is easy; simply pry open the snap-on mechanism for easy inspection and replacement of the wire or rubber pad screws, reducing maintenance costs. The straight grooves and openings of the profile guide rail provide operating space for angled or straight driving of the screws, adapting to different wall materials such as concrete and tiles. The equidistant arrangement of the straight grooves can also serve as installation marks, ensuring uniform spacing of the rubber pad screws, improving the uniformity of force distribution, avoiding installation inconvenience caused by the guide rail structure, solving the problem of easy damage when drilling traditional guide rails, and improving work efficiency.

[0020] (3) The side cover fits seamlessly with the profile guide rail via a snap-fit ​​mechanism, resulting in a smooth and flat appearance. After covering, it completely conceals the rubber gaskets, screws, and steel wires, creating an "invisible" effect. This eliminates the large gaps left by traditional side covers, which easily trap dirt and grime. The self-tapping screws used to fix the side cover are exposed, resulting in an unsightly appearance and no enhanced protection. This design meets the aesthetic requirements of modern architectural decoration. The closed cavity design not only enhances the protective performance but also prevents dust accumulation or rainwater seepage from the gaps, ensuring the product remains clean for a long time.

[0029] 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.

[0030] The following combination Figures 1 to 7 This application will be described in further detail.

[0031] This application discloses an invisible protective net profile structure, including a profile guide rail 1 and a side cover 6. The side cover 6 is fixed to the profile guide rail 1 by a snap-fit ​​method. The outer side of the top plate and the outer side of the bottom plate of the profile guide rail 1 are respectively provided with a snap-fit ​​position A9 and a snap-fit ​​position B10. The inner side of the top plate and the inner side of the bottom plate of the side cover 6 are respectively provided with a snap-fit ​​strip A11 and a snap-fit ​​strip B12 that are fastened to the snap-fit ​​position A and the snap-fit ​​position B10.

[0032] The snap-fit ​​structure eliminates the need for tools such as rubber pads, screwdrivers, and wrenches; the side cover 6 and the profile guide rail 1 can be fixed simply by pressing. Compared to traditional self-tapping screw fixing methods, installation time is shortened, making it especially suitable for high-altitude operations or batch construction scenarios. Disassembly is easy; simply pry open the snap-fit, facilitating later inspection and replacement of the protective net wire 2 or rubber pad screws, thus reducing maintenance costs.

[0033] The precise fit between clip A and clip A, and clip B and clip B, ensures a tight connection between the side cover 6 and the profile guide rail 1, preventing dust accumulation or rainwater seepage. This also results in a smooth, flat appearance, enhancing the overall aesthetics of the product (traditional fixing with rubber pad screws 3 leaves exposed holes, affecting visual appeal). The side cover 6 completely conceals the rubber pad screws 3 and steel wire of the profile guide rail 1, creating an "invisible" effect that meets the aesthetic requirements of modern architectural decoration.

[0034] The profile guide rail 1 has rubber-coated screws 3 arranged in an orderly manner to install and support the protective wire mesh 2. The profile guide rail 1 has thickened reinforcing ribs A8 and two symmetrically arranged raised reinforcing ribs B7 located within the profile cavity of the profile guide rail 1. During installation, the rubber-coated screws 3 are driven through the reinforcing ribs A8 and then positioned between the two raised reinforcing ribs B7, forming support for the end of the rubber-coated screw 3. The rubber-coated screw 3 includes a screw body 31 and an I-shaped rubber pad 32 fitted onto the screw body 31. The I-shaped rubber pad 32 is used to cooperate with the protective wire mesh 2 for winding installation (e.g.,...). Figure 7 (As shown).

[0035] The reinforcing ribs on the profile guide rail 1 used to fix the rubber pad screws 3 have a double-layer design (an outer thickened reinforcing rib A7 + two symmetrically arranged inner reinforcing ribs B8). The rubber pad screws 3 are fixed by penetrating both layers of reinforcing ribs. When the protective net is impacted, the force exerted on the rubber pad screws 3 is more evenly distributed across the entire profile through the double-layer reinforcing ribs. Secondly, after the protective net is impacted, the deformation of the rubber pad screws 3 is reduced due to the double-layer reinforcing ribs providing support from both the front and rear. The double-layer reinforcing rib design achieves stronger support for the protective net by evenly dissipating force and stably locking the deformation of the rubber pad screws 3. Figure 4 and Figure 6 As shown, the protective wire mesh 2 is installed on the rubber pad screw 3, which is supported and limited by two layers of reinforcing ribs.

[0036] The double-layer reinforcing ribs 7, in conjunction with the rubber-coated screws 3, disperse the shear force and torque on the rubber-coated screws 3 when the protective net is impacted (such as by external force or wind vibration), reducing the degree of tilting deformation of the rubber-coated screws 3 (compared to the single-layer reinforcing rib design), ensuring a more stable fixation of the steel wire. The rubber-coated screws 3 form a wrapping and limiting effect on the steel wire, preventing the steel wire from shifting or slipping at the fixing point of the rubber-coated screws 3, which is especially suitable for high-frequency vibration environments (such as the protection of exterior windows in high-rise residential buildings). The double-layer reinforcing ribs 7 evenly distribute the force on the rubber-coated screws 3, preventing excessive stress at a single point from causing the rubber-coated screws 3 to break, thus improving the fatigue life of the rubber-coated screws 3.

[0037] After the side cover 6 is placed on the profile guide rail 1, the protective wire mesh 2 and the rubber pad screws 3 are sealed in the profile cavity formed by the profile guide rail 1 and the side cover 6.

[0038] After the side cover 6 is fastened, it encloses the steel wire within the profile cavity. When the rubber pad screw 3 loosens due to external force, the snap-fit ​​structure between the side cover 6 and the profile guide rail 1 helps to limit the displacement of the steel wire. Combined with the secondary support of the aluminum alloy profile, this forms a "double insurance" protection mechanism. The enclosed profile cavity isolates the rubber pad screw 3 from the outside air, rain, and moisture, which reduces the rate of rust and oxidation of the rubber pad screw 3 (compared to the exposed rubber pad screw 3 design), making it especially suitable for use in humid or coastal areas. The side cover 6 blocks direct sunlight, preventing the steel wire from aging and becoming brittle due to ultraviolet radiation, thus extending the service life of the protective net. The enclosed cavity formed by the profile guide rail 1 and the side cover 6 is equivalent to "encapsulating" the steel wire, rubber pad screw 3, reinforcing rib 7, and other components within a rigid structure, thereby increasing the overall tensile strength of the protective net and enabling it to withstand greater impact forces.

[0039] The top plate of the profile guide rail 1 is provided with straight grooves 4 at equal intervals between the inlet and outlet of the protective wire mesh 2, and the top plate of the profile guide rail 1 is provided with openings 5 ​​at equal intervals that communicate with the straight grooves 4.

[0040] When the profile guide rail 1 is fixed, the straight groove 4 and the opening 5 provide operating space for the mounting screw 13 that passes through the profile guide rail 1, so that the drill bit can drive the screw 13 at an angle or straight.

[0041] The evenly spaced straight grooves 4 serve as installation markers, ensuring uniform spacing of the rubber pad screws 3, improving the uniformity of stress on the protective mesh, and avoiding localized stress concentration. The straight grooves 4 and openings 5 ​​provide the drill bit with operating space for inclined or vertical drilling, adapting to the installation needs of different wall materials (such as concrete and tiles), avoiding the limitation of a single installation angle due to the guide rail structure. Traditional guide rails do not have straight grooves 4 and openings 5, requiring the drill bit to be angled during drilling, which is inconvenient. The current straight grooves 4 and openings 5 ​​provide the drill bit with operating space for inclined or vertical drilling, making operation convenient.

[0042] After the side cover 6 is closed with the profile guide rail 1, the side cover 6 covers the opening 5 and exposes the straight groove 4. When the rubber pad screw 3 becomes loose and falls off, the closed cavity formed by the top plate of the profile guide rail 1 and the side cover 6 provides secondary restraint for the protective net wire 2, so that the protective net wire 2 will not directly detach from the profile due to the rubber pad screw 3 falling off, thus providing secondary support for the protective net.

[0043] When the rubber pad screw 3 loosens, the top plate of the profile guide rail 1 and the straight groove 4 form a limiting structure. Even if the rubber pad screw 3 comes out partially, it will be stuck by the straight groove 4 and will not fall off (in traditional designs, if the rubber pad screw 3 falls off, it will fall directly). The double support structure greatly enhances the overall safety of the protective net. Even if the rubber pad screw 3 loosens and falls off, the top plate of the profile guide rail 1 can provide a second support to prevent the protective net from collapsing.

[0044] This invisible protective net profile structure, through designs such as snap-fit ​​connection, double-layer reinforcing ribs 7, closed cavity, and straight groove 4 limiting, solves the pain points of traditional protective nets from multiple dimensions, including mechanical support, ease of installation, environmental adaptability, and safety redundancy. It not only improves product performance but also meets the comprehensive needs of modern buildings for aesthetics, safety, and durability, and has significant practical value and market competitiveness.

[0045] The specific steps for installing this invisible protective netting profile structure are as follows:

[0046] I. Installation Preparation

[0047] Materials and tools: Prepare 1 profile guide rail, 6 side covers, 2 protective wire mesh, 13 mounting screws (select 3 expansion rubber pad screws or 3 self-tapping rubber pad screws according to the wall material), electric drill, 3 rubber pad screwdrivers, spirit level, tape measure, and marker pen.

[0048] Wall survey: Confirm the installation location (such as window or balcony edge), check the wall flatness with a spirit level, and address any obvious unevenness in advance. Use a tape measure to measure the length and height of the installation area to determine the number and location of the profile guide rail 1 splices, ensuring a uniform overall layout.

[0049] Profile pretreatment: According to the measured dimensions, use a cutting machine to cut the profile guide rail 1 to the appropriate length. Check whether the straight groove 4 and opening 5 of the profile guide rail 1 are intact, and remove internal burrs and debris. On the top plate of the profile guide rail 1, use a marker pen to mark the installation points of the rubber washer screws 3 according to the position of the straight groove 4, ensuring uniform spacing (generally, a spacing of 30-50cm is recommended, which can be adjusted according to the load-bearing requirements of the protective net).

[0050] II. Fixing of Profile Guide Rail 1

[0051] Positioning and Drilling: Attach the profile guide rail 1 to the wall according to the marked positions. Use a spirit level to calibrate the horizontal and vertical alignment, ensuring the profile guide rail 1 is installed correctly. Using the straight groove 4 and opening 5 as references, use an electric drill to drill holes in the wall through opening 5. For concrete walls, use an impact drill to drill holes for expansion joint screws 3; for tile or wooden walls, you can directly drill holes for self-tapping screws 3. When drilling, the drill bit can be used to choose between angled or straight drilling through the straight groove 4 and opening 5 to adapt to different wall materials and avoid a single installation angle due to the limitations of the guide rail structure.

[0052] Fixing the guide rail: Pass the mounting screws 13 through the straight groove 4 and the opening 5, and screw them into the wall hole. First, fix the screws 13 at both ends, and then fix the middle screws 13 in sequence to ensure that the profile guide rail 1 is tightly fitted to the wall. During the fixing process, use a spirit level to check the flatness of the profile guide rail 1 at any time. If there is any deviation, adjust the tightness of the screws 13 in time.

[0053] III. Steel Wire Installation and Support

[0054] Wire threading: Insert the protective net wire 2 into the inlet position at one end of the profile guide rail 1, and pass it through each rubber pad screw 3 in sequence. During threading, the rubber pad screw 3 forms a wrapping and limiting effect on the wire, preventing the wire from shifting or slipping at the fixing point of the rubber pad screw 3.

[0055] Secure the rubber pad screws 3: At each rubber pad screw 3 location, tighten the rubber pad screw 3 with a screwdriver to ensure a tight fit between the double-layer reinforcing ribs and the rubber pad screw 3, providing support for the rubber pad screw 3. The double-layer reinforcing ribs 7, in conjunction with the rubber pad screw 3, can disperse the shear force and torque on the rubber pad screw 3, reducing the degree of tilting deformation of the rubber pad screw 3 and ensuring a more stable wire fixation.

[0056] IV. Side Cover 6 Installation

[0057] Alignment of clips: Align the clip A of the side cover 6 with the clip A of the profile guide rail 1, and the clip B with the clip B to ensure precise positioning. The precise fit between the clips and clips ensures a tight connection between the side cover 6 and the profile guide rail 1, preventing dust accumulation or rainwater seepage through gaps.

[0058] Press-fit: No tools such as rubber pads, screwdrivers, or wrenches are needed. Simply press the side cover 6 evenly to securely fasten clip A to clip A and clip B to clip B. During installation, press from one end to the other to ensure a seamless fit between the side cover 6 and the profile guide rail 1, enhancing the overall aesthetics of the product. After the side cover 6 is in place, it completely conceals the rubber pads, screwdrivers, and steel wires of the profile guide rail 1, giving the product an "invisible" effect.

[0059] V. Inspection and Debugging

[0060] Overall inspection: After installation, check whether the snap connection between the side cover 6 and the profile guide rail 1 is tight, and whether there is any looseness or gap. Observe whether the profile guide rail 1 is firmly fixed, and whether there is any tilting or shaking.

[0061] Steel wire tension test: Gently pull the protective net steel wire 2 to check whether the steel wire is firmly fixed and whether there is any loosening or slippage. For high-frequency vibration environments such as exterior window protection of high-rise residential buildings, it is necessary to focus on testing the stability of the steel wire under vibration.

[0062] Rubber pad screw 3 limit verification: Simulate the situation of rubber pad screw 3 being loose, check whether the top plate of profile guide rail 1 and straight groove 4 play a limiting role for the loose rubber pad screw 3, and ensure that the rubber pad screw 3 cannot fall out of straight groove 4 and detach from profile guide rail 1.

[0063] VI. Maintenance and Precautions

[0064] Routine maintenance: Regularly check whether the snap connection between the side cover 6 and the profile guide rail 1 is loose. If it is loose, press it to tighten it in time. Check whether the rubber gasket screws 3 are rusted or oxidized. For humid or coastal areas, the inspection frequency can be increased.

[0065] Disassembly and maintenance: When it is necessary to inspect or replace the protective net wire 2 or the rubber pad screw 3, simply pry open the buckle to remove the side cover 6, which facilitates later maintenance and reduces maintenance costs.

[0066] Safety Tips: When working at heights, wear safety belts and other protective equipment to ensure construction safety. During installation, avoid using tools such as electric drills to prevent damage to the profile guide rail 1, which may affect product performance.

[0067] 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.
