Description

Technical Field

[0001] This utility model relates to the field of corner strip technology, specifically a corner strip that is easy to install. Background Technology

[0002] An external corner strip is a decorative trim used to treat the external corners of walls. It is usually made of materials such as PVC, aluminum alloy, and stainless steel. It is long and narrow with a 90-degree fan-shaped arc on one side. In decoration, the external corner strip can protect the corners of the walls and prevent damage to the edges of the tiles. At the same time, it can make the corners of the walls more beautiful and neat, enhancing the decorative effect. The installation of external corner strips is very convenient, saving labor, time and materials.

[0003] Corner strips made of different materials each have their own characteristics. PVC corner strips are affordable and come in a variety of colors; aluminum alloy corner strips are sturdy and durable with a good texture; stainless steel corner strips are corrosion-resistant, rust-proof, and have a long service life. The length of corner strips is generally around 2.5 meters, and the appropriate size can be selected according to the thickness of the tiles. There are large and small corner strips, which are suitable for tiles of different thicknesses. In short, corner strips are a practical and beautiful decoration material.

[0004] Chinese Utility Model Patent Publication No. CN106381984B discloses: a corner strip that is easy to construct. This corner strip improves construction convenience, provides precise angle control, and results in good wall quality. Plaster or glue can be applied between the third and fourth strips to enhance the aesthetics and waterproofing of the corner. However, it does not have a dividing groove for the corner strip, requiring it to be cut during construction. This requires a high level of skill from the workers and is prone to damaging the board or causing chipping at the edges, which seriously affects the aesthetics. Any mistakes will increase the waste of the board. Furthermore, the lack of a curved structure for the corner strip means that if a 45° chamfer is strictly followed in actual operation, a thin and sharp right angle will be formed, posing a risk of cuts and making it susceptible to damage from impacts. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an external corner strip that is easy to construct, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is as follows: a corner strip that is easy to construct, comprising a wall, an embedded plate on the outer side of the wall, a corner strip on the side of the embedded plate away from the wall, a corner strip reinforcing plate inside the corner strip, a through-hole nail hole on the side of the embedded plate away from the wall, a steel nail extending into the wall through the nail hole, a fixing post one fixedly installed on the side of the embedded plate away from the wall, slots on both sides of the fixing post one, a fixing post two installed on the side of the corner strip near the fixing post one, a buckle on the inner side of the fixing post two, a partition groove on the inner surface of the corner strip and the reinforcing plate, a connecting seat fixedly installed on the outer side of the straight edge of the corner strip, a leveling layer partition and a decorative panel on the outer side of the corner strip, a connecting groove on the side of the leveling layer partition and the decorative panel near the corner strip, and an insertion cavity inside the corner strip.

[0007] Preferably, the dividing grooves are distributed at equal intervals on the inner surfaces of the corner strip and the reinforcing plate, and the dividing grooves in the corner strip and the dividing grooves in the reinforcing plate are not located at the same level.

[0008] The above technical solution, by creating dividing grooves on the inner surfaces of the corner strips and reinforcing plates, facilitates on-site cutting by workers, eliminating the need for cutting machines and reducing time costs. The insertion and installation of the reinforcing plates strengthens the corner strips, preventing deformation and increasing their service life and safety.

[0009] Preferably, the cross-section of the slot is triangular, the cross-section of the buckle is triangular, the slot and the buckle are adapted to each other, and the number of slots and buckles is the same.

[0010] Through the above technical solution, by setting the slots and buckles to match, after the workers have installed the embedded plate, it can be quickly connected to the embedded plate through the buckles on the corner strip, which can achieve rapid positioning. By setting multiple sets of slots and buckles, deformation can be prevented.

[0011] Preferably, the corner strip is made of PVC material, and the cross-section of the corner strip is Y-shaped, with the included angle between the two sides being perpendicular.

[0012] Through the above technical solutions, the PVC corner strips greatly enhance the strength of the wall corners, effectively preventing cracking, significantly improving service life and safety performance. At the same time, they are easy to install, have low installation difficulty, and low cost. In addition, by setting the corner strips at a 90° angle between the two sides, they can more accurately fit the embedded plate design.

[0013] Preferably, the connecting seat has an "L" shaped structure, and the leveling layer partition and the decorative panel are plugged into the connecting seat. The connecting seat, the leveling layer partition and the decorative panel are provided in two identical sets, and the two sets of the connecting seat, the leveling layer partition and the decorative panel are distributed at 90°.

[0014] The above technical solution, by setting a connecting seat that matches the connecting groove on the leveling layer partition and the decorative panel, facilitates quick positioning by the workers. The leveling layer partition also makes it easier for workers to pour cement or other building materials. Furthermore, adhesive can be applied to the back of the leveling layer partition to bond the decorative panel, greatly reducing the workers' measurement time.

[0015] Preferably, the cross-sectional shape of the reinforcing plate is the same as that of the insertion cavity of the corner strip, and the reinforcing plate and the corner strip are installed by insertion.

[0016] With the above technical solution, the user can manually adjust the length of the reinforcing plate to be the same as that of the corner strip during construction. By inserting and installing it with the corner strip, the strength of the corner strip can be enhanced, preventing damage during use and effectively increasing the stability and service life of the corner strip.

[0017] Preferably, the embedded plate has a Y-shaped cross-section with the included angle between the two sides being perpendicular. The embedded plate is made of stainless steel and its height is the same as the height of the wall.

[0018] By using the above technical solution, and setting the included angle of the embedded plate to 90°, the embedded plate can better fit the wall during construction, making it easier for construction workers to fix the embedded plate. The vertical distribution also has a certain degree of stability, avoiding repeated corrections and positioning by construction workers. The stainless steel embedded plate is fixed to the formwork during construction, and then concrete is poured to form a solid structure, improving the overall stability.

[0032] 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.

[0033] Example 1: As Figure 1-7 As shown, this utility model provides a corner strip that is easy to construct, including a wall 1, an embedded plate 2 on the outer side of the wall 1, a corner strip 3 on the side of the embedded plate 2 away from the wall 1, a corner strip reinforcing plate 4 inside the corner strip 3, a through nail hole 5 on the side of the embedded plate 2 away from the wall 1, a steel nail 6 between the wall 1 and the embedded plate 2, and a fixing post 7 fixedly installed on the side of the embedded plate 2 away from the wall 1, with openings on both sides of the fixing post 7. The corner strip 3 has a slot 8, a fixing post 9 is provided on the side of the corner strip 3 near the fixing post 7, a buckle 10 is provided on the inner side of the fixing post 9, a partition groove 11 is provided on the inner surface of the corner strip 3 and the reinforcing plate 4, a connecting seat 12 is fixedly installed on the outer side of the straight edge of the corner strip 3, a leveling layer partition 13 and a decorative panel 14 are provided on the outer side of the corner strip 3, a connecting groove 15 is provided on the side of the leveling layer partition 13 and the decorative panel 14 near the corner strip 3, and an insertion cavity 16 is provided inside the corner strip 3.

[0034] Specifically, the dividing grooves 11 are evenly distributed on the inner surfaces of the corner strip 3 and the reinforcing plate 4. The dividing grooves 11 in the corner strip 3 and the dividing grooves 11 in the reinforcing plate 4 are not at the same level. The advantage is that by opening the dividing grooves 11 on the inner surfaces of the corner strip 3 and the reinforcing plate 4, it is convenient for construction personnel to cut on the construction site without the need to use a cutting machine, which reduces the technical requirements for construction personnel. Furthermore, by inserting and installing the reinforcing plate 4 inside the corner strip 3, the strength of the corner strip 3 is greatly enhanced.

[0035] Specifically, the cross-section of the slot 8 is triangular, and the cross-section of the buckle 10 is triangular. The slot 8 and the buckle 10 are compatible, and the number of slots 8 and buckles 10 is the same. The advantage is that by setting the slots 8 and buckles 10 to be compatible, after the workers have installed the embedded plate 2, it can be quickly connected to the embedded plate 2 through the buckles 10 on the corner strip 3, which can achieve rapid positioning. By setting multiple sets of slots 8 and buckles 10, deformation can be prevented.

[0036] Specifically, the external corner strip 3 is made of PVC material. The cross-section of the external corner strip 3 has a "Y" shaped structure, and the included angle between the two sides is perpendicular. The advantages are that the PVC material greatly enhances the strength of the wall external corner, effectively prevents cracking, significantly improves service life and increases the safety performance of the external corner. At the same time, it is easy to construct, with low construction difficulty and low cost. In addition, by setting the two sides of the external corner strip 3 to 90°, it can more accurately fit the design of the embedded plate 2.

[0037] Example 2: Figure 1-7 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, the connecting seat 12 has an "L" shaped structure. The leveling layer partition 13 and the decorative panel 14 are plugged into the connecting seat 12. There are two identical sets of connecting seats 12, leveling layer partition 13 and decorative panel 14. The two sets of connecting seats 12, leveling layer partition 13 and decorative panel 14 are distributed at 90°. The advantage is that by setting the connecting seat 12 to match the connecting groove 15 on the leveling layer partition 13 and decorative panel 14, it is convenient for workers to quickly position the components. Furthermore, the leveling layer partition 13 makes it easy for workers to pour cement or other building materials. Adhesive can be applied to the back of the leveling layer partition 13 to bond the decorative panel 14, which greatly reduces the measurement time for workers.

[0039] Specifically, the cross-sectional shape of the reinforcing plate 4 is the same as the insertion cavity 16 of the corner strip 3. The reinforcing plate 4 and the corner strip 3 are installed by insertion. The advantage is that during construction, the user can manually adjust the length of the reinforcing plate 4 to be the same as that of the corner strip 3. By inserting it into the corner strip 3, the strength of the corner strip 3 can be strengthened, avoiding damage during use and effectively increasing the stability and service life of the corner strip 3.

[0040] Specifically, the embedded plate 2 has a "Y" shaped cross-section with the included angle between the two sides being vertically distributed. The embedded plate 2 is made of stainless steel and its height is the same as that of the wall 1. The advantage is that by setting the included angle of the embedded plate 2 to 90°, the embedded plate 2 can better fit the wall 1 during construction, making it easier for construction workers to fix the embedded plate 2. The vertical distribution also provides a certain degree of stability, avoiding repeated corrections and positioning by construction workers. The stainless steel embedded plate is fixed to the wall 1 during construction, and then concrete is poured to form a solid structure, improving the overall stability.

[0041] Working principle: During use, construction workers use steel nails 6 to fix the embedded plate 2 to the outside of the wall 1 through the nail holes 5. The dimensions of the corner strip 3 and reinforcing plate 4 can be quickly adjusted through the partition grooves 11 on the inner surfaces of the corner strip 3 and reinforcing plate 4. Then, the reinforcing plate 4 is inserted into the inside of the corner strip 3, increasing its strength and making it less prone to damage. The slots 8 on the fixing column 7 and the clips 10 on the corner strip 3 are matched, and the number of slots 8 and clips 10 is the same, enabling rapid installation of the embedded plate 2 and corner strip 3. The multiple sets of slots 8 and clips 10 help prevent deformation. The leveling layer partition 13 and the finishing layer can be quickly installed through the connecting seats 12 on both sides of the corner strip 3. The board 14 facilitates quick positioning by workers, and the gap between the leveling layer partition 13 and the wall 1 allows workers to easily pour cement or other building materials. Adhesive can be applied to the other side of the leveling layer partition 13 for bonding the decorative panel 14. The corner strip 3 is made of PVC, which improves its strength, effectively prevents cracking, and extends its service life. It is easy to construct, has low construction difficulty, and low cost. The corner strip 3 has a 90° arc structure, and the arc is set on the outer surface of the corner strip 3, which effectively avoids users from hitting the right-angle corner strip 3 and being scratched, greatly improving safety and making it very suitable for widespread use.

[0042] 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.
