Description

Technical Field

[0001] This invention relates to the field of decoration and renovation technology, specifically to a stepped edge component and a method for installing stepped wall panels. Background Technology

[0002] Patent CN211817192U discloses a stepped wall, which includes a component that is embedded and fixed to a first wall panel and another component that is embedded and fixed to a second wall panel. The two components are connected by a snap-fit ​​structure of a protrusion and a groove.

[0003] The above solution has the following drawbacks: it uses two components (metal encapsulation and connector) to fix the two wall panels respectively, and the two components need to be snapped together. If there is a slight horizontal / vertical deviation in the installation of the wall panels, or if there is a dimensional error in the processing of the snap protrusions and grooves, it is very easy to encounter situations where the snapping is not smooth, loosening after snapping, or even failure to snap together. If there are errors in the processing of the components and the ends of the wall panels, it will be difficult to connect and fix the components to the wall panels. It also requires high requirements for the manufacturing and processing technology of the two components and a high level of skill from the construction personnel. Summary of the Invention

[0004] The purpose of this invention is to provide a stepped edge trim component that has low production and processing requirements and is easy to install.

[0005] To achieve the above objectives, the present invention employs a stepped edge component, comprising a first connecting portion for connecting to a first wall panel and a second connecting portion for connecting to a second wall panel. An integrally formed first connecting segment perpendicular to the connection between the first and second connecting portions is provided between the first and second connecting portions. The first connecting portion forms a laterally open fixing groove. The second connecting portion has a support segment for supporting the front side of the second wall panel. The extension direction of the support segment is the same as the opening direction of the fixing groove, and the support segment is fixed to the second wall panel by fasteners.

[0006] The first connecting portion, first connecting segment, and second connecting portion of the component of this invention are integrally formed structures, eliminating the need for high-precision mating structures such as protrusions and grooves, as well as the need for butt-fitting operations between the two parts of the component, thus lowering the requirements for component manufacturing and processing. Furthermore, it eliminates the need for high-precision alignment of the two wall panels, the need for machining grooves at the ends of the wall panels, and the need for further processing of the wall panels, further reducing the dimensional accuracy requirements for the first and second connecting portions of the component, and making installation easier.

[0007] During installation, simply embed the entire end of the first wall panel into the fixing groove, and then attach the second wall panel to the support section and fix it with fasteners. The integrated structure of the components provides a natural positioning benchmark for the wall panel installation. There is no need for construction personnel to manually and repeatedly calibrate the relative positions of the two wall panels or the docking positions between the components, which greatly reduces the calibration difficulty during installation. Even less skilled construction personnel can achieve stepped wall panel installation.

[0008] Preferably, the first connecting portion includes a second connecting segment extending forward, a front fixing segment extending in the left-right direction, and a rear fixing segment. One end of the front fixing segment and one end of the rear fixing segment are integrally connected through the second connecting segment to form the fixing groove with a lateral opening. The front fixing segment is shorter than the rear fixing segment.

[0009] The front fixing section is shorter than the rear fixing section, making the front contact surface of the fixing groove shorter and the rear contact surface longer. The long rear contact surface provides the main vertical positioning reference for the first wall panel, ensuring the overall verticality of the wall panel installation. The short front contact surface reserves a small adjustment gap. If there are dimensional deviations in the processing of the end of the first wall panel (such as uneven thickness or uneven end), or if there are slight horizontal deviations in the on-site installation, the first wall panel will not get stuck due to hard contact on the front side when it is embedded in the fixing groove, which greatly reduces the accuracy requirements for wall panel processing and on-site installation.

[0010] Preferably, the front end of the first connecting segment is connected to the other end of the rear fixing segment, and the rear end of the first connecting segment is connected to the offset end of the support segment.

[0011] When the second wall panel is fitted with the fixing groove, the first connecting part will be subjected to force and the force will be transmitted to the first connecting section. This invention connects the first connecting section and the rear fixing section at a point away from the bottom of the fixing groove, so that the lateral force on the first connecting part will be transmitted to the first connecting section after passing through a longer rear fixing section. This can avoid the lateral force directly impacting the connection point, prevent cracking at the connection point between the first connecting section and the first connecting part, and reduce the overall deformation of the component caused by excessive local stress.

[0012] Preferably, one of the two adjacent surfaces of the front and rear fixed sections is provided with an elastic co-extruded layer, and the other surface is provided with bite teeth continuously arranged in the left-right direction.

[0013] The continuously arranged interlocking teeth along the left and right direction will mechanically engage with the end face of the first wall panel after it is embedded in the fixing groove. The elastic co-extruded layer (such as rubber or soft plastic elastic material) on the opposite side will be squeezed and deformed when the first wall panel is embedded, filling all the tiny gaps between the fixing groove and the wall panel. This eliminates the abnormal noise caused by the gaps during use (hard contact friction caused by thermal expansion and contraction / slight vibration), and also forms a continuous clamping force on the first wall panel through the rebound force, strengthening the tightness of the connection. The fixing effect of the combination of the two is more stable than that of a purely rigid connection, and the first wall panel will not loosen or shift even after long-term use.

[0014] Preferably, the front fixing section is provided with the biting teeth, and the end of the front fixing section with the biting teeth is provided with barbs.

[0015] A barb is provided at the end of the meshing tooth surface of the front fixed section. After the wall panel is embedded in the fixing groove, the barb will be inserted into the surface / gap of the wall panel in the opposite direction, forming a one-way locking structure, which further restricts the shaking of the first wall panel relative to the component.

[0016] Preferably, the support section includes a first support section located directly behind the first connecting portion and a second support section located to the side of the first connecting portion. The second support section is fixed to the second wall panel by fasteners and is located directly behind the first wall panel.

[0017] Preferably, the first connecting portion and the second connecting portion form a placement groove that opens to one side for placing the light strip, and the opening direction of the placement groove is opposite to the opening direction of the fixing groove.

[0018] The present invention also discloses a method for installing a stepped wall panel using the above-mentioned stepped edge trimming component, comprising the following steps: S1. Install the first leveling keel and the second leveling keel on the wall to complete the leveling treatment of the first leveling keel and the second leveling keel, so that there is a front-to-back difference between the first leveling keel and the second leveling keel; S2. Fix the second wall panel at the second leveling keel; S3. Fix the edge trimming step component to the front side of one end of the second wall panel; S4. Apply adhesive to the first leveling keel so that the first wall panel is close to the first leveling keel; S5. Move the first wall panel horizontally and embed the end of the first wall panel into the edge trim component.

[0019] Preferably, after step S3 or step S5, a light strip is arranged on the edge-sealing step member.

[0020] This invention has the advantages of requiring lower requirements for component production and processing, facilitating installation, and requiring lower skill levels from construction personnel. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Example 1

[0026] Depend on Figures 1 to 3 As shown, this embodiment discloses a stepped edge trim component 300, including a first connecting portion for connecting to a first wall panel 100 and a second connecting portion for connecting to a second wall panel 200. An integrally formed first connecting segment 1 perpendicular to the connection between the first and second connecting portions is provided. The first connecting portion forms a laterally open fixing groove 20. The second connecting portion has a support segment 3 for supporting the front side of the second wall panel 200. The extending direction of the support segment 3 is the same as the opening direction of the fixing groove 20, and the support segment 3 is fixed to the second wall panel 200 by fasteners 30. A decorative layer 4 is provided on the surfaces of the stepped edge trim component 300 that are not in contact with the first wall panel 100 or the second wall panel 200. The decorative layer 4 serves both decorative and protective functions.

[0027] The first connecting part includes a second connecting section 21 extending forward, a front fixing section 22 extending in the left and right direction, and a rear fixing section 23. One end of the front fixing section 22 and one end of the rear fixing section 23 are integrally connected through the second connecting section 21 to form a side-opening fixing groove 20. The front fixing section 22 is shorter than the rear fixing section 23.

[0028] The front end of the first connecting section 1 is connected to the other end of the rear fixing section 23, and the rear end of the first connecting section 1 is connected to the support section 3 at the off-end. The support section 3 includes a first support section 31 located directly behind the first connecting section and a second support section 32 located to the side of the first connecting section. The second support section 32 is fixed to the second wall panel 200 by fasteners. The second support section 32 is located directly behind the first wall panel 100, and the second support section 32 is provided with a relief groove 321 that opens forward to allow the bolt head of the fastener to pass.

[0029] The rear end face of the front fixing section 22 is provided with continuously arranged biting teeth 221 in the left-right direction. In this embodiment, the length of the front fixing section 22 in the left-right direction is 15-25mm. The biting surface of the biting teeth 221 is an arc surface with an arc diameter of 0.5-1mm, and the gap depth between adjacent biting teeth 221 is 0.2-0.5mm. The above arrangement makes the rear end face of the front fixing section 22 closer to a plane, which facilitates the insertion of the end of the first wall panel 100. The end of the surface of the front fixing section 22 with the biting teeth is provided with barbs 222.

[0030] An elastic co-extruded layer 231 is provided at the front end face of the rear fixed section 23, and the length of the rear fixed section 23 in the left-right direction is 1.5 to 2.5 times the length of the front fixed section 22 in the left-right direction.

[0031] In this embodiment, the first connecting portion and the second connecting portion form a placement groove 40 that opens to one side for placing the light strip 400. The opening direction of the placement groove 40 is opposite to the opening direction of the fixing groove 20. The placement groove 40 is formed between the rear fixing section 23, the first connecting section 1 and the supporting section 31. Example 2

[0032] Depend on Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the edge-trimming step component in this embodiment does not have a placement groove for arranging light strips. In this embodiment, the end of the support section 3, the end of the rear fixing section 23, and the rear end of the second connecting section 21 are integrally connected by a third connecting section 10, and a cavity is formed between the rear fixing section 23, the third connecting section 10, the support section 31, and the first connecting section 1. Example 3

[0034] S1. Install a first leveling keel 51 and a second leveling keel 52 on the wall 600 to complete the leveling process of the first leveling keel 51 and the second leveling keel 52, so that there is a front-to-back difference between the first leveling keel 51 and the second leveling keel 52.

[0035] S2. Fix the second wall panel 200 at the second leveling keel 52 with structural adhesive.

[0036] S3. Fix the edge trimming step component 300 to one end of the front side of the second wall panel 200.

[0037] S4. Apply structural adhesive to the first leveling keel 51, and before the structural adhesive cures, make the first wall panel 100 close to the first leveling keel 51.

[0038] S5. Before the structural adhesive cures, move the first wall panel 100 horizontally and embed the end of the first wall panel 100 into the fixing groove 20 of the edge-trimming step component 300. After step S3 or S5, place a light strip 400 in the placement groove 40 of the edge-trimming step component 300.
