Description

Technical Field

[0001] This utility model relates to the field of interior decoration, and specifically to a recessed floor trim.

[0002] summary

[0003] This utility model provides a portable, split-type snap-on installation device for baseboards, designed to solve the problem of adjustable installation when there are errors in the level of the junction between the floor and the hard-decorated wall, or when there is a large gap between the floor tiles or flooring and the hard-decorated wall. Background Technology

[0004] During interior decoration construction, gaps or level differences ranging from 2-10mm often occur at the junction of the floor tiling layer (such as floor tiles or flooring) and the hard-decorated walls due to construction errors. Traditional integrated baseboards, due to their fixed structure, cannot effectively compensate for these errors, resulting in problems such as poor finishing and visual unevenness, which seriously affects the overall aesthetics of the interior decoration.

[0005] Currently, existing technologies typically address these issues by filling with adhesive or on-site cutting and correction. However, filling with adhesive is not only inefficient but also prone to aging and cracking, affecting aesthetics and service life; on-site cutting and correction requires advanced construction skills and makes it difficult to guarantee cutting accuracy, also resulting in poor aesthetics.

[0006] Furthermore, traditional integrated skirting boards have poor error compatibility, unable to simultaneously compensate for verticality errors in hard-decorated walls exceeding 3mm and floor gaps exceeding 2mm. Moreover, during construction, latex paint application and skirting board installation must be carried out simultaneously, which easily leads to a finished product contamination rate exceeding 15%.

[0007] While existing split-type skirting boards allow for separate installation, the L-shaped brackets lack a dedicated structure for positioning plasterboard, resulting in a 12% cracking rate of latex paint at corners. Furthermore, these skirting boards rely solely on clip-on connections, posing a high risk of dislodgement under vibration, and thus failing to meet the stability requirements of practical use. Utility Model Content

[0008] The purpose of this invention is to provide a portable, split-type snap-on mounting lead wire to solve the aforementioned problems in the prior art.

[0009] The portable split-type snap-on mounting lead wire provided by this utility model specifically includes the following structure:

[0010] Asymmetrical cross-section aluminum alloy bracket formed by continuous bending: This bracket consists of an upper fixed wing plate, a middle web plate, and a lower load-bearing wing plate. The middle web plate extends laterally, connecting the upper fixed wing plate and the lower load-bearing wing plate into a single unit. The lower load-bearing wing plate is fixedly connected to the hard wall using fasteners. The inner side of the upper fixed wing plate forms a through-type limiting groove with the inner side of the hard wall, used for positioning and fixing the plasterboard. After the lower load-bearing wing plate is connected to the wall with fasteners, its bottom end can tightly abut against the floor paving layer, providing stable support for the entire skirting board structure.

[0011] Gypsum board: Its size is adapted to the limiting groove, making it suitable for embedding in the limiting groove and forming a mechanical interlocking structure with the aluminum alloy bracket to enhance overall stability.

[0012] Latex paint layer: Covers the outer surface of the upper fixed wing plate and the surface of the gypsum board, serving both decorative and protective purposes.

[0013] Aluminum alloy skirting board: It is fixed to the outer side of the lower load-bearing wing plate with an adhesive layer. It is used to cover the gap between the floor paving layer and the hard wall, and its position can be adjusted according to actual needs.

[0014] In some embodiments, the limiting groove has a depth of 1.5-2 mm and a width of 3-5 mm, and is provided continuously along the length of the bracket. This dimensional design ensures an interference fit between the gypsum board and the limiting groove, further improving the connection strength between the gypsum board and the aluminum alloy bracket, thereby enhancing the adhesion of the latex paint layer.

[0015] In some embodiments, the bottom end of the lower bearing wing plate is provided with a polyurethane elastic sealing gasket. This sealing gasket has good elasticity and sealing performance, which can effectively compensate for the difference in ground level. When there is a ground level difference of about 2mm, it can still be tightly pressed against the surface of the floor tiles to prevent dust, moisture and other substances from entering the gaps, while improving the sealing and aesthetics between the skirting board and the ground.

[0016] In some embodiments, the lower support wing plate is provided with screw holes and / or nail positioning slots. These structures enable rapid positioning and fixing of the aluminum alloy bracket to the rigid wall, greatly improving construction efficiency. Construction workers can choose to use screws or nails for installation according to the actual situation, making the operation simple and quick.

[0017] In some embodiments, the aluminum alloy baseboard is an inverted L-shape. This shape design not only better conceals the gap between the floor paving layer and the hard wall, but also makes the transition between the baseboard and the hard wall and floor more natural and smooth, enhancing the overall aesthetics of the interior decoration.

[0018] In some embodiments, the outer wall surface of the upper fixed wing plate is provided with barbed micro-protrusions. These micro-protrusions can significantly increase the contact area between the upper fixed wing plate and the latex paint layer, thereby improving the adhesion of the latex paint layer. Tests have shown that the adhesion between the wing plate surface with micro-protrusions and the latex paint can reach 1.8 MPa, significantly reducing the paint film cracking rate compared to smoother surfaces. Optionally, the micro-protrusions can adopt parabolic, trapezoidal, or honeycomb hexagonal structures, etc., which can also enhance adhesion.

[0019] In some embodiments, the angle between the middle web plate and the upper fixed wing plate is 90°±2°, and the angle between the middle web plate and the lower bearing wing plate is 90°±2°. The wall thickness of the aluminum alloy bracket is 1.2-1.5mm. This angle and wall thickness design ensures both the structural strength and stability of the aluminum alloy bracket and provides it with a certain degree of elastic deformation capability. It can accommodate a verticality error of ±5mm in the hard-decorated wall and a ground gap error of ±3mm, effectively solving the problem of traditional skirting boards being sensitive to construction errors.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The asymmetric aluminum alloy bracket's elastic deformation capability allows for tolerance to ±5mm verticality errors in hard-wall installations and ±3mm floor gap errors, solving the problem of traditional skirting boards being sensitive to construction errors. Actual testing showed that it maintains good sealing even with an 8mm gap, effectively ensuring both the aesthetics and practicality of the interior decoration.

[0022] The mechanical interlocking between the limiting groove and the embedded plasterboard improves the adhesion of the latex paint layer by more than 40%. Meanwhile, the barbed micro-protrusions on the outer wall of the upper fixed wing plate further enhance adhesion to the latex paint layer, significantly reducing cracking at corners and improving the lifespan and decorative effect of the baseboard.

[0023] The split design separates the hard surface preparation and baseboard installation processes. Construction workers can first prepare the hard surface and apply latex paint, then install the aluminum alloy baseboards after the paint has cured, effectively avoiding contamination of the finished product. The gun-nail positioning grooves on the lower load-bearing flange enable rapid positioning, greatly improving construction efficiency. Furthermore, the dual fixing method of adhesive layer and mechanical clips showed no dislocation during vibration testing, demonstrating improved reliability compared to a pure clip connection method, ensuring the stability and safety of the baseboards during use.

[0026] This embodiment provides a portable split snap-on mounting baseboard, the specific structure of which includes a continuously bent asymmetrical cross-section aluminum alloy bracket, gypsum board 4, latex paint layer 5 and aluminum alloy baseboard 9.

[0027] The aluminum alloy bracket includes an upper fixed wing plate 1, a middle web plate 2, and a lower load-bearing wing plate 3. The middle web plate 2 extends laterally to connect the upper fixed wing plate 1 and the lower load-bearing wing plate 3. The lower load-bearing wing plate 3 is fixedly connected to the hard wall 6 by fasteners. The inner side of the upper fixed wing plate 1 and the inner side of the hard wall 6 form a through-type limiting groove. After the lower load-bearing wing plate 3 is connected to the wall by fasteners, its bottom end abuts against the ground paving layer 8. The gypsum board 4 is suitable for embedding in the limiting groove. The latex paint layer 5 covers the outer surface of the upper fixed wing plate 1 and the gypsum board 4. The aluminum alloy skirting board 9 is fixed to the outer facade of the lower load-bearing wing plate 3 by an adhesive layer 10.

[0028] For example, the middle web plate 2 forms a 90°±2° angle with the upper fixed wing plate 1 and the lower bearing wing plate 3, and the wall thickness is 1.35mm±0.05mm. A 4mm×1.8mm limiting groove is provided on the inner side of the upper fixed wing plate 1, and the gypsum board 4 is interference-fitted with the limiting groove to ensure that the gypsum board 4 is stable and reliable after installation. Testing shows that the adhesion strength between the latex paint layer 5 and the upper fixed wing plate 1 is ≥1.2MPa. When the outer wall surface of the upper fixed wing plate 1 has barbed micro-protrusions, the adhesion between the wing plate surface with the micro-protrusions and the latex paint reaches 1.8MPa, significantly reducing the cracking rate of the paint film compared to a smooth surface. The micro-protrusions can adopt parabolic, trapezoidal, or honeycomb hexagonal structures, etc.

[0029] The bottom of the lower load-bearing wing plate 3 integrates a polyurethane sealing strip with a Shore hardness of 45±5. The polyurethane sealing gasket at the bottom can be tightly pressed against the surface of the floor tiles, effectively compensating for a 2mm floor drop. A thick gypsum board 4, matching the size of the groove, is embedded in the limiting groove, ensuring that the gypsum board 4 is flush with the outer surface of the upper fixed wing plate 1. Then, putty is applied, and after the putty dries, a latex paint layer 5 is applied, covering the corner area of ​​the upper fixed wing plate 1 and the gypsum board 4, ensuring a beautiful and consistent decorative effect.

[0030] The lower support flange 3 is equipped with screw holes and wide nail slots, allowing construction personnel to choose the appropriate fixing method according to the actual situation. After the latex paint has cured, apply adhesive to the back of the inverted L-shaped aluminum alloy baseboard 9, and press it to the vertical surface of the lower support flange 3 to complete the installation of the entire baseboard.

[0031] Exemplarily, this embodiment provides an installation process for baseboards: First, using M4 self-tapping screws or brad nails, the aluminum alloy bracket is fixed to the hard wall 6 through the screw holes and brad nail positioning grooves on the lower support wing plate 3. Then, plasterboard 4 is inserted into the limiting groove, and latex paint is applied to the outer surface of the upper fixing wing plate 1. After the floor is laid and the latex paint is fully cured, MS adhesive (with an initial tack > 0.5 MPa and a final strength > 2.0 MPa) is applied to the back of the aluminum alloy baseboard 9, and the aluminum alloy baseboard 9 is installed on the lower support wing plate 3. The two are then pressed together to ensure a tight connection, completing the adhesive installation.

[0032] Tested according to GB / T 23446-2009:

[0033] Water tightness: This baseboard can withstand 0.3MPa water pressure without leakage, effectively preventing moisture from entering the gaps in the wall and floor, and protecting the indoor environment.

[0034] Thermal cycling (-20℃-80℃): After 50 cycles, the seam change rate is <0.15%, indicating that the skirting board has good structural stability under different temperature environments and will not deform or crack due to temperature changes.

[0035] Impact resistance: In a drop test with a 500g steel ball from a height of 1m, the lead wire showed no deformation, demonstrating strong impact resistance and the ability to withstand various collisions in daily use.

[0036] The above embodiments fully verify the reliability and adaptability of this utility model in engineering practice, and it is particularly suitable for the standardized installation requirements of prefabricated decoration. Its split-type baseboard structure facilitates better connection between the corners of the hard-decorated wall and the latex paint, improving the decorative effect; on the other hand, it facilitates the installation and adjustment of the baseboard, reducing construction difficulty and improving construction efficiency. The aluminum alloy bracket, as one of the key components of this utility model, features a continuous groove design that facilitates adhesion to latex paint, and the aluminum alloy material has excellent corrosion resistance and strength, effectively ensuring the product's service life and providing a stable installation foundation. In actual use, the user first fixes the aluminum alloy baseboard bracket to the wall, choosing to use screws, nail guns, or other methods for fixing as needed. Then, the plasterboard 4 is inserted into the upper recess, and the latex paint surface is applied for masking. Finally, depending on the depth or horizontal gap between the floor tiling layer and the wall, the aluminum alloy baseboard 9 is adjusted back-to-back or horizontally at the exposed aluminum alloy baseboard bracket at the bottom to complete the entire installation process.
