Description

Technical Field

[0001] A decorative strip for covering joints in building walls and a method for using and installing the same relate to covering and beautifying joints in building walls, and in particular to a decorative strip for covering joints in building walls bonded with a non-chemical adhesive and a method for using and installing the same. Background Art

[0002] Wall trim is a commonly used decorative material in the construction industry, primarily used to cover and enhance gaps between internal and external wall materials, corners, and windows. Currently, these types of wall trim are typically applied after wall construction, plastering, and painting are complete. These strips are invariably bonded to the wall using chemical adhesives. Because the antioxidant properties of chemical adhesives are affected by factors such as temperature, humidity, and dust, their adhesion is extremely unstable in certain environments. Even after eliminating these environmental factors that can affect chemical adhesive oxidation, numerous factors, including the wall's flatness and roughness, the compatibility of the wall material or trim with the chemical adhesive, and construction quality, can affect the strip's adhesion. In conclusion, the decorative strips bonded with chemical adhesives are currently prone to yellowing of the adhesive seams, debonding and warping, and falling off of the decorative strips after a period of time after the decoration construction is completed. The occurrence of the above-mentioned problems not only affects the aesthetic appearance of the building wall decoration, but also may cause falling objects from high altitudes and certain safety accidents if the falling of the decorative strips on the building exterior wall is not handled in a timely manner. Currently, many wall panels have decorative layers attached to their surfaces, and the installation flatness and firmness of the decorative strips are required to be high. However, the chemical adhesives available on the market are all formaldehyde glue or urea-formaldehyde glue. The stronger the bonding force, the higher the formaldehyde or urea-formaldehyde content in the glue. The contradiction between the firmness of the decorative strip installation and the harmful substance content of the chemical adhesive is very prominent in the building decoration industry. At present, there is no decorative strip for wall seam beautification that is both firmly installed and environmentally friendly in the field of building decoration materials. Summary of the Invention

[0003] To address the above-mentioned issues, the present invention provides a decorative strip for covering seams in building walls and a method for its use and installation. The decorative strip comprises a cover plate and a tenon strip, the tenon strip being fixedly mounted on the cover plate and provided with a tensioning structure. The decorative strip also comprises a corner joint, the tenon strip b being fixedly mounted on the corner joint and provided with a tensioning structure. The decorative strip of the present invention departs from the traditional chemical adhesive bonding method used by conventional decorative strips. Instead, the decorative strip is physically bonded to the wall using an adhesive slurry or grouting slurry that is more compatible with building wall materials and more environmentally friendly.

[0004] Specifically, during the construction of building wall panels, when the wall panel bonding slurry has not yet solidified, the tenon strips provided on the decorative strips are inserted into the joints between the wall panels or between the wall panels and the beams, columns, and the ground; or after the wall panel bonding slurry has solidified, the tenon strips and the tensioning structure on the decorative strips are fixedly bonded to the joints between the wall panels or between the wall panels and the beams, columns, and the ground through the grouting slurry, so as to realize the function of the decorative strips to cover and beautify the connection seams of the building walls.

[0005] In order to enhance the physical tensile strength between the decorative strip and the wall panel bonding slurry or the grouting slurry, a tensioning structure is provided on the tenon strip and can be provided as a single tensioning structure.

[0006] Specifically, the single-body tensioning structure is a barb at the lower end of the tenon, several hooks on the tenon, the tenon is arranged in a trapezoidal shape that is wide on the outside and narrow on the inside, the tenon is arranged in an S shape, several through holes are provided on the tenon, and several concave tooth structures with a circular defect less than half of the full circle are provided on the lower end surface of the tenon b.

[0007] In order to further enhance the physical tensile strength between the decorative strip and the wall panel bonding slurry or the grouting slurry, a tensioning structure is provided on the tenon strip, which can be configured as a composite tensioning structure.

[0008] Specifically, the composite tensioning structure is provided by simultaneously providing a barb at one end of the tenon and a through hole on the tenon, providing a plurality of barbs on the tenon and a through hole, providing a plurality of through holes on a tapered tenon with a wide outer surface and a narrow inner surface, or providing a plurality of through holes on an S-shaped tenon.

[0009] The present invention provides a decorative strip for covering gaps in building walls, comprising an L-shaped internal corner decorative strip I1, a flat decorative strip 2, an L-shaped internal corner decorative strip II3, and an L-shaped external corner decorative strip 4. Its corner connectors include an L-shaped adapter, a T-shaped adapter, a T-shaped tee adapter, a four-way adapter 54, a external corner miter tee adapter 55, a internal corner flat tee adapter 56, and a internal corner miter tee adapter 57.

[0010] Specifically, the tenon of the L-shaped internal corner decorative strip Ⅰ1 is arranged parallel to any side of the covering plate, and is used to cover and beautify the gap between the wall panel and the beam, column, and ground, or to cover and beautify the internal corner gap in the 90-degree corner of the wall panel.

[0011] Specifically, the tongue and tongue of the flat decorative strip 2 is arranged along the vertical direction of the covering plate, and is used to cover and beautify the horizontal wall gaps between two wall panels or between a wall panel and a beam, column, or ground.

[0012] Specifically, the tenon strip of the L-shaped internal corner decorative strip II3 is arranged along the direction of the bisector of the outer side angle of the covering plate, and is used to cover and beautify the 45-degree miter internal corner gap in the 90-degree corner of two wall panels.

[0013] Specifically, the tenon strip of the L-shaped external corner decorative strip 4 is arranged along the inner side angle bisector direction of the covering board, and is used to cover and beautify the 45-degree miter external corner gap in the 90-degree corner of two wall panels.

[0014] The ends of the four decorative strips, L-shaped internal corner decorative strip Ⅰ1, flat decorative strip 2, L-shaped internal corner decorative strip Ⅱ3 and L-shaped external corner decorative strip 4, are connected in three ways: 45-degree bevel connection, 90-degree plug-in connection or three-side 45-degree bevel connection.

[0015] In order to enhance the decorative effect of the decorative strip and make it consistent with the indoor and outdoor decoration style, the surface patterns and designs of the decorative strip are enriched. The decorative strip also includes a decorative panel, which is covered on the outer surface of the cover plate.

[0016] Specifically, (1) the decorative panel is clamped at both ends of the cover plate by a clamp head to achieve the connection between the decorative panel and the cover plate. (2) the decorative panel d is inserted into the cover plate slot by a clamp claw to achieve the connection between the decorative panel and the cover plate.

[0017] Preferably, the shape of the decorative panel d of the L-shaped inner corner decorative strip I1, the flat decorative strip 2, the L-shaped inner corner decorative strip II3, and the L-shaped outer corner decorative strip 4 is consistent with the shape of the covering plate a.

[0018] The buckling mode of the cover plate a and the decorative panel d of the four decorative strips is adopted in the above installation method, that is, they are used separately or installed as a whole after buckling or installed separately and then buckled.

[0019] Specifically, decorative strips are not used independently of decorative panels; instead, the cover plate independently covers and beautifies the wall gaps. During installation, the decorative panel is first snapped onto the outer surface of the cover plate. The decorative panel and cover plate are then cut and installed together. Alternatively, the cover plate can be cut and installed separately. After the adhesive or grouting slurry has cured, the decorative panel, cut into its various angles, is snapped onto the outer surface of the cover plate.

[0020] The present invention provides a decorative strip for covering seams in building walls and a method for using and installing the same. The beneficial effect is that the decorative strip includes a cover plate and a tenon strip, and the cover plate and the tenon strip together form a T-shaped structure, so that the decorative strip has higher physical performance indicators such as shear resistance and warping resistance. The decorative strip is combined with the wall body using a wall panel bonding slurry or a grouting slurry. The bonding slurry and the grouting slurry are more compatible with building wall materials. Not only is the bonding force stronger than traditional chemical adhesives, but they are also more environmentally friendly. A tensioning structure is provided on the tenon strip, so that the connection strength between the decorative strip and the bonding slurry or the grouting slurry is higher. The composite tensioning structure provided on the tenon strip further strengthens the connection strength between the decorative strip and the bonding slurry or the grouting slurry. The decorative strip can be used alone or in combination with a decorative panel. The installation method of snapping together after split installation can effectively avoid damage and scratches to the decorative pattern on the outer surface of the decorative strip during the construction process.
