Description

Technical Field

[0001] The utility model relates to the technical field of external corners, in particular to a high temperature resistant curved external corner. Background Art

[0002] A positive angle usually refers to a protruding wall corner, such as the angle formed by two walls at the turn of a walkway, or the four protruding corners on the outside of a building, as well as the angle between door and window openings and the wall. It is one of the structures of a building.

[0003] When scraping putty on the corners, workers need to hold the external corner strip with their hands, and then scrape putty on one end of the external corner strip, and then scrape putty on the other end of the external corner strip to fix the curved external corner body to the wall. However, this method is time-consuming and reduces the efficiency of workers in scraping putty. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-temperature resistant curved external angle to solve the problem mentioned in the above background technology that when scraping putty on the wall corner, workers need to hold the external angle strip with their hands, and then scrape putty on the external angle strip at one end, and then scrape putty on the external angle strip at the other end to fix the curved external angle body to the wall. However, this method is time-consuming and also reduces the efficiency of workers in scraping putty.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high temperature resistant curved external angle, comprising a curved external angle main body, both side end faces of the curved external angle main body are provided with a plurality of raised blocks in a linear array, the inner end face of the curved external angle main body is provided with four attachment layers, the attachment layers are provided with release paper for protecting the attachment layers, a reserved groove is provided between the raised blocks at both ends of the curved external angle main body, four first reserved holes in a linear array are provided on the surface of the curved external angle main body, a plurality of second reserved holes in a linear array are provided on the raised blocks, the thickness of the curved external angle main body is 5 mm,

[0006] By adopting the above technical scheme, the four release papers attached to the inner end surface of the curved outer corner body are torn off. When the release papers are torn off, the attachment layer is not protected. After the release papers are torn off, the inner corner of the curved outer corner body is aligned with the wall to be puttyed, so that the attachment layer drives the curved outer corner body to be attached to the wall corner. Because the attachment layer has a certain viscosity, the curved outer corner body can be better attached to the wall corner, and the curved outer corner body can be better prevented from warping when puttying. Then, because the reserved grooves are set between the raised blocks, the workers can make the curved outer corner body better fit with the wall corner when puttying. At the same time, the first reserved hole and the second reserved hole can better connect the putty to the wall through the first reserved hole and the second reserved hole, so as to ensure that the curved outer corner body is better fitted to the wall corner.

[0007] Preferably, connection blocks are fixedly installed at the top positions of both ends of the curved male angle body, and two connection grooves are provided at the bottom positions of both ends of the curved male angle body. The thickness of the connection block is 2.9 mm, and the width of the connection groove is 3 mm.

[0008] By adopting the above technical scheme, the connecting block installed on the top of the bent external angle is inserted into the connecting groove opened at the bottom of another bent external angle. Then, since the groove width of the connecting groove is 3 mm and the thickness of the connecting block is 2.9 mm, the connecting block can be inserted into the connecting groove, thereby extending the main body of the bent external angle, so that workers can better adapt the main body of the bent external angle to wall corners of different heights when scraping putty.

[0009] Preferably, a corner guard is provided at the right-angle end of the curved male corner body, and the corner guard is in an arc shape.

[0010] By adopting the above technical solution, the corner protector set by bending the right-angle end of the external corner body into an arc shape can prevent the end of the putty scraped from the corner from being sharp, thereby protecting objects or human bodies.

[0011] Preferably, a high temperature resistant coating is sprayed on the surface of the curved external corner body, and the material of the high temperature resistant coating sprayed on the curved external corner body is silica sol.

[0012] By adopting the above technical scheme, the surface of the bent external corner body is sprayed with silica sol, and the silica sol has good high temperature resistance, can make the coating firm, and has functions such as anti-fouling and dust-proof, aging-resistant, and fire-proof. It can better extend the service life of the bent external corner body, and also effectively increase the high temperature resistance of the bent external corner body.

[0013] Preferably, the curved male corner body is designed at a right angle, the distance between the two ends of the curved male corner body is 90°, and the material used for the curved male corner body is PVC material.

[0014] By adopting the above technical solution, the inner angle of the bent external corner body is 90° so that it can better fit between the wall corners. Since the material used for the bent external corner body is PVC material, PVC material has good durability, waterproof and moisture-proof, fire retardant and chemical corrosion resistance, and is environmentally friendly and non-toxic, it can better improve the service life of the bent external corner body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The high-temperature resistant curved external corner is made by tearing off the four release papers attached to the inner end surface of the curved external corner body. After the release papers are torn off, the attached layer has a certain viscosity, so the curved external corner body can be better attached to the wall corner, and the curved external corner body can be better prevented from warping when scraping putty. Then, the reserved grooves arranged between the raised blocks can enable the workers to better fit the curved external corner body to the wall corner when scraping putty, so as to ensure that the curved external corner body is better attached to the wall corner, thereby preventing the workers from needing to hold the curved external corner body with their hands when scraping putty on the wall corner.

[0017] 2. This high-temperature resistant curved external angle is inserted into a connecting groove opened at the bottom of another curved external angle through a connecting block installed at the top of the curved external angle. Since the groove width of the connecting groove is 3mm and the thickness of the connecting block is 2.9mm, the connecting block can be inserted into the connecting groove to extend the main body of the curved external angle, so that workers can better adapt the main body of the curved external angle to wall corners of different heights when scraping putty.

[0018] 3. This high-temperature resistant curved external corner is sprayed with silica sol on the surface of the curved external corner body, and the silica sol has good high-temperature resistance, can make the coating firm, and has functions such as anti-fouling and dust-proof, aging-resistant, and fire-proof. It can better extend the service life of the curved external corner body, and also effectively increase the high-temperature resistance of the curved external corner body.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] Please refer to Figure 1-4 , a high temperature resistant curved male angle, the end faces of both sides of the curved male angle body 1 are provided with a plurality of raised blocks 2 in a linear array, the inner end face of the curved male angle body 1 is provided with four attachment layers 3, and the attachment layer 3 is provided with a release paper 4 for protecting the attachment layer 3, and a reserved groove 5 is provided between the raised blocks 2 at both ends of the curved male angle body 1, the surface of the curved male angle body 1 is provided with four first reserved holes 6 in a linear array, and the raised blocks 2 are provided with a plurality of second reserved holes 7 in a linear array, the thickness of the curved male angle body 1 is 5 mm, and a corner guard 10 is provided at the right-angle end of the curved male angle body 1, and the shape of the corner guard 10 is arc-shaped, the curved male angle body 1 is designed at a right angle, and the spacing between the two ends of the curved male angle body 1 is 90°.

[0027] Working principle: When workers need to putty the corners of the wall, they generally need to use the positive angle to protect the corners of the wall, so as to prevent the corners from being damaged and thus extend the life of the corners. First, tear off the four release papers 4 attached to the inner end surface of the curved positive angle body 1. When the release papers 4 are torn off, the pasting layer is not protected. After the release papers 4 are torn off, align the inner angle of the curved positive angle body 1 with the wall to be puttyed, so that the attachment layer 3 drives the curved positive angle body 1 to be attached to the corner. Because the inner angle of the curved positive angle body 1 is 90°, it can better fit with the corner. Because the attachment layer 3 has a certain degree of viscosity, the curved positive angle body 1 can be better attached to the corner, and it can also better prevent the curved positive angle body 1 from warping when scraping putty, so that the worker does not need to hold the positive angle strip with his hand and then use putty to fix the positive angle strip when scraping putty on the corner. The situation is improved to improve the work efficiency of the workers. Then, because the raised blocks 2 are arranged at both ends of the bent external corner strip, the bent external corner body 1 can be better fitted with the wall corner. Then, the thickness of the bent external corner strip body is 5 mm. After the putty is scraped, the bent external corner body 1 can be better integrated with the wall without making the complete external corner body stand out. Then, because the reserved grooves 5 are arranged between the raised blocks 2, the workers can make the bent external corner body 1 better fit with the wall corner when scraping the putty. At the same time, the first reserved hole 6 and the second reserved hole 7 can better connect the putty with the wall through the first reserved hole 6 and the second reserved hole 7 to ensure that the bent external corner body 1 is better fitted to the wall corner. Then, because the corner guard 10 arranged at the right-angle end of the bent external corner body 1 is arc-shaped, the putty end point scraped from the wall corner can be prevented from being sharp, thereby protecting objects or human bodies.

[0028] Embodiment 2:

[0029] Please refer to Figure 1-4 A high temperature resistant curved male angle, wherein connecting blocks 8 are fixedly installed at the top positions of both ends of the curved male angle body 1, and two connecting grooves 9 are provided at the bottom positions of both ends of the curved male angle body 1. The thickness of the connecting block 8 is 2.9 mm, and the width of the connecting groove 9 is 3 mm.

[0030] Working principle: Since the heights of walls that need to be puttyed are different, the required lengths of the curved external angles are also different. If the length of the curved external angle main body 1 is not long enough when scraping putty, the connecting block 8 installed on the top of the curved external angle can be inserted into the connecting groove 9 opened at the bottom of another curved external angle. Then, since the groove width of the connecting groove 9 is 3mm and the thickness of the connecting block 8 is 2.9mm, the connecting block 8 can be inserted into the connecting groove 9 to extend the main body of the curved external angle, so that the workers can better adapt the curved external angle main body 1 to wall corners of different heights when scraping putty.

[0031] Embodiment 3:

[0032] Please refer to Figure 1-4 A high temperature resistant curved external corner, the material used for the curved external corner body 1 is PVC material, the surface of the curved external corner body 1 is sprayed with a high temperature resistant coating 11, and the material of the high temperature resistant coating 11 sprayed on the curved external corner body 1 is silica sol.

[0033] Working principle: The material used for the bent external corner body 1 is PVC material, because PVC material has good durability, waterproof and moisture-proof, fire retardant and chemical corrosion resistance, and is environmentally friendly and non-toxic. Then the high-temperature resistant coating 11 sprayed on the surface of the bent external corner body 1 is a silica sol, and the silica sol has good high-temperature resistance, and can make the coating firm, and has functions such as anti-fouling and dust-proof, aging-resistant, and fire-proof. It can better extend the service life of the bent external corner body 1, and also effectively increase the high-temperature resistance of the bent external corner body 1.
