A decorative molding which is easy to install and fix

Abstract

This utility model relates to the field of decorative molding technology, specifically a decorative molding that is easy to install and fix. It includes a decorative molding body, with silicone pads inserted at each of the four corners of the body. Double-sided adhesive sponge is inserted into the surface of each silicone pad. The surface of the decorative molding body has adhesive grooves, and both ends have adhesive-holding grooves. The advantages are: when the decorative molding with applied adhesive is pressed onto the wall, the double-sided adhesive sponge quickly bonds to the wall while the adhesive is still wet, achieving pre-positioning of the decorative molding. Simultaneously, the contact between the silicone pads and the wall increases the friction between the decorative molding body and the wall, effectively preventing the decorative molding from falling off due to external force or its own weight during the adhesive drying process. This greatly improves the stability and accuracy of installation, reducing the number of adjustments and rework during installation.

Description

Technical Field

[0001] This utility model relates to the field of decorative moldings, specifically a decorative molding that is easy to install and fix. Background Technology

[0002] In the field of interior and exterior decoration, decorative moldings, as an important decorative element, are widely used in the decoration of walls, ceilings, and other parts, serving to beautify spaces, divide areas, and conceal structural defects. However, traditional methods of installing decorative moldings have many problems, seriously affecting installation efficiency and quality.

[0003] On the one hand, traditional installation methods lack effective pre-positioning measures. During installation, workers usually need to manually support the decorative moldings while waiting for the adhesive to dry and cure to achieve a fixed effect. However, during this period before the adhesive dries, the decorative moldings are highly susceptible to displacement, tilting, or even detachment due to external force, uneven wall surfaces, or worker errors. This not only leads to inaccurate installation positions and affects the decorative effect but may also damage the decorative moldings, increasing construction costs and time.

[0004] On the other hand, the bonding strength between adhesive and decorative moldings / walls in traditional installation methods is insufficient. Ordinary decorative moldings have relatively smooth surfaces, and after applying adhesive, the adhesive tends to flow downwards under gravity, resulting in uneven distribution and insufficient filling of the gaps between the moldings and the wall. Furthermore, the adhesive relies solely on simple contact surfaces for bonding, lacking an effective mechanical interlocking structure. Over long-term use, factors such as temperature and humidity changes, and vibration can easily lead to problems like delamination and detachment, affecting the lifespan and safety of the decorative moldings.

[0005] While some improved decorative molding installation structures exist on the market, most are complex, increasing production difficulty and cost; others have poor pre-positioning effects, failing to effectively prevent the moldings from detaching during adhesive drying; still others are insufficient in enhancing adhesive bonding strength, failing to fundamentally solve the problem of easy detachment. Therefore, developing a decorative molding that is easy to install and fix, effectively pre-positions, and firmly bonds to the wall is of significant practical importance. Utility Model Content

[0006] The purpose of this utility model is to provide a decorative molding that is easy to install and fix, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a decorative line that is easy to install and fix, comprising a decorative line body, wherein silicone pads are inserted into the four corners of the decorative line body, and double-sided sponge adhesive is inserted into the surface of the silicone pads. The surface of the decorative strip body is provided with glue - hanging hair grooves, and glue - clamping grooves are provided at both ends of the decorative strip body.

[0008] Preferably, edge grooves are provided at the four corners of the decorative strip body, silicone cushion blocks are fixed inside the edge grooves, and the thickness of the silicone cushion blocks is equal to the depth of the edge grooves.

[0009] Preferably, the surface of the silicone cushion block is provided with notch grooves, double - sided sponge glue penetrates through the notch grooves and is fixed on the surface of the edge grooves, the thickness of the double - sided sponge glue is greater than that of the silicone cushion block, and a release paper sheet is provided at one end of the double - sided sponge glue away from the edge groove.

[0010] Preferably, the glue - clamping groove is a "convex" - shaped groove, there are two glue - clamping grooves in each group, and the two glue - clamping grooves are both distributed inside the glue - hanging hair groove.

[0011] Preferably, the length of the long side of the glue - hanging hair groove is equal to the length of the long side of the decorative strip body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The decorative strip that is convenient for installation and fixation proposed by the present utility model presses the decorative strip smeared with glue on the wall surface. At this time, the glue is not dry, and the double - sided sponge glue can quickly bond with the wall surface to achieve the pre - positioning of the decorative strip. At the same time, the silicone cushion block contacts the wall surface, increasing the friction between the decorative strip body and the wall surface, effectively preventing the decorative strip from falling off due to external force or its own gravity during the drying process of the glue, greatly improving the stability and accuracy of installation, and reducing the adjustment times and rework rate during the installation process.

[0013] The glue - hanging hair groove is opened on the surface of the decorative strip body, and the length of the long side is equal to the length of the long side of the decorative strip body. When glue is smeared on one side of the decorative strip that needs to contact the wall surface, the glue can hang on the glue - hanging hair groove, effectively avoiding the problem of uneven distribution caused by the dripping of the glue, enabling the glue to fill more evenly between the decorative strip and the wall surface, and enhancing the bonding effect.

[0014] The glue - clamping grooves opened at both ends of the decorative strip body are "convex" - shaped grooves, there are two in each group and they are distributed inside the glue - hanging hair groove. Part of the glue will soak into the glue - clamping grooves. When the glue cures, a "convex" - shaped clamping block is formed between the glue - clamping grooves and the wall surface.

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a decorative line that is easy to install and fix, including a decorative line body 1, with silicone pads 3 inserted at each of the four corners of the decorative line body 1, and double-sided sponge adhesive 5 inserted on the surface of the silicone pads 3; a side groove 2 is provided at each of the four corners of the decorative line body 1, the silicone pads 3 are fixed inside the side groove 2, and the thickness of the silicone pads 3 is equal to the depth of the side groove 2; a notch 4 is provided on the surface of the silicone pads 3, and the double-sided sponge adhesive 5 passes through the notch 4 and is fixed to the surface of the side groove 2, the thickness of the double-sided sponge adhesive 5 is greater than the thickness of the silicone pads 3, and a release paper 6 is provided at the end of the double-sided sponge adhesive 5 away from the side groove 2.

[0018] When installing the decorative line body 1, in order to pre-position the decorative line body 1 on the wall to prevent it from falling off, the release paper 6 is peeled off from the surface of the double-sided sponge adhesive 5, and then the decorative line body 1 with glue is pressed onto the wall. At this time, the glue is not dry, and the decorative line body 1 is temporarily attached to the wall by the double-sided sponge adhesive 5. The silicone pad 3 contacts the wall to increase the friction between the decorative line body 1 and the wall, preventing the decorative line body 1 from falling off.

[0019] To improve the firmness of the decorative molding body 1 when fixed to the wall with glue, the following is proposed: The surface of the decorative line body 1 is provided with a glue-hanging hair groove 8, and both ends of the decorative line body 1 are provided with glue-locking grooves 7. The glue-locking grooves 7 are in the shape of a "convex" groove. Each group of glue-locking grooves 7 has two, and the two glue-locking grooves 7 are both distributed inside the glue-hanging hair groove 8. The length of the long side of the glue-hanging hair groove 8 is equal to the length of the long side of the decorative line body 1.

[0020] When glue is applied to the side of the decorative line body 1 that needs to contact the wall, the glue hangs on the glue-hanging hair groove 8 to prevent the glue from flowing down, and part of the glue soaks into the glue-locking grooves 7. When the glue solidifies, a "convex"-shaped clamping block is formed between the glue-locking grooves 7 and the wall, further preventing the decorative line body 1 from falling off.

[0021] Usage method of the decorative line convenient for installation and fixation: This decorative line convenient for installation and fixation is applicable to various indoor and outdoor wall decoration scenarios, such as the wall decoration of the living room and bedroom in a family residence, the wall beautification of a shopping mall and a hotel in a commercial place, and the wall decoration of an office and a meeting room in an office area, etc. Taking the wall decoration of the living room in a family residence as an example, the length of the living room wall is usually 3 - 6 meters, and the height is about 2.5 - 3 meters. Using this decorative line can enhance the beauty and layering of the wall.

[0022] Use sandpaper (with a mesh number of 120 - 180) to polish the wall to remove impurities such as dust, oil stains, and loose particles on the wall. For the uneven parts on the wall, use putty for repair. The drying time of the putty depends on the ambient temperature and humidity, generally 2 - 4 hours. After the putty is completely dry, polish the wall with sandpaper again to make the flatness error of the wall not exceed ±2 mm. Wipe the wall with a wet cloth to remove the dust generated by polishing. After the wall is dry, proceed to the next installation step. Check whether the decorative line body 1 is damaged, deformed, etc. If cracks, bending and other problems are found on the decorative line, it should be replaced in time. Check whether the silicone cushion block 3 is firmly inserted into the side groove 2, whether the double-sided sponge glue 5 completely penetrates the notch groove 4 and is fixed on the surface of the side groove 2, and whether the release paper 6 is intact.

[0023] Accurately measure the length and height of the wall using a measuring tape. Determine the installation location and quantity of the decorative moldings based on the measurements. For example, if the wall length is 4.5 meters, use two 2.5-meter-long decorative moldings joined together. Use a level to determine the horizontal line for the installation of the decorative moldings on the wall, and mark the upper and lower boundary lines on the wall with a pencil, ensuring the boundary line error does not exceed ±1mm. Pick up the decorative molding body 1 and clean the surface of the double-sided adhesive sponge 5 with release paper remover, ensuring the surface is free of dust and impurities. Carefully peel the release paper 6 off the surface of the double-sided adhesive sponge 5, moving gently to avoid damaging the double-sided adhesive sponge. The thickness of the double-sided adhesive sponge 5 is generally 1-2mm thicker than the silicone pad 3 to ensure a good temporary bonding effect. Use a caulking gun to evenly apply neutral silicone adhesive to the side of the decorative molding body 1 that will contact the wall, with a thickness of approximately 3-5mm. Ensure the adhesive fully fills the adhesive groove 8. The long side of the adhesive-coating groove 8 is equal to the long side of the decorative strip body 1, effectively holding the adhesive and preventing it from running. Some adhesive will seep into the retaining groove 7, which is a U-shaped groove. Each set of retaining grooves 7 has two, both located inside the adhesive-coating groove 8. After the adhesive cures, a U-shaped retaining block is formed between the retaining groove 7 and the wall, further preventing the decorative strip body 1 from detaching. After applying more adhesive, press the decorative strip body 1 back onto the wall, ensuring full contact between the adhesive and the wall, and squeeze out any excess adhesive. Use a scraper to clean up any squeezed-out adhesive, ensuring the decorative strip adheres tightly to the wall with a surface flatness error not exceeding ±1mm. After the adhesive has fully cured (generally 24-48 hours, depending on ambient temperature and humidity), check that the decorative strip body 1 is securely installed. Gently shake the decorative molding body 1 by hand. If there is no obvious shaking and no separation between the adhesive and the wall or the decorative molding, the installation is considered successful. When applying the adhesive, ensure even distribution to avoid areas that are too thick or too thin. Gently press the decorative molding body 1, with the adhesive applied, onto the wall according to the marked positions, ensuring a tight fit. While the adhesive is still wet, the decorative molding body 1 is temporarily bonded to the wall using double-sided sponge adhesive 5. Simultaneously, the silicone pad 3 contacts the wall to increase friction and prevent the decorative molding body 1 from detaching. Immediately after installation, use a level to check if the decorative molding body 1 is level. If it is not level, gently move the decorative molding body 1 to adjust it before the adhesive is fully cured (generally within 10-15 minutes). The adjustment range should not exceed ±2mm. Wait for the adhesive to initially cure (approximately 30-60 minutes, depending on the ambient temperature and adhesive type). During this time, the double-sided sponge adhesive 5 provides temporary fixation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
