Description

Technical Field

[0001] The utility model relates to the technical field of home decoration, and more specifically to a door and window accessory, and more specifically to a door and window casing. Background Art

[0002] In the field of building home decoration, for a building wall surface, it is usually necessary to make an opening in the wall surface to install a window or a door leaf. Usually, the inner end surface of the opening has stubble left by construction. In order to cover the stubble and to provide a window frame that serves as a basic frame for installing a window sash or a door leaf, it is necessary to install a door and window casing on the inner end surface of the opening, so as to cover the stubble and improve the aesthetics. And after the door and window casing covers the four inner end surfaces of the opening, a window frame is formed integrally (for further installing a window sash or a door leaf on the basis of the window frame).

[0003] The existing door and window casings can usually only cover the inner end surface of the opening, but cannot cover the vertical surface of the opening at the same time, thus greatly affecting the aesthetics. In addition, the existing door and window casings are usually very short and need to be spliced in multiple sections to cover the wall thickness of the entire inner end surface of the opening, so there will be many splicing gaps on the overall product, which also affects the aesthetics of the entire window frame to a certain extent.

[0004] Therefore, it is necessary for the industry to provide an improved door and window casing to overcome the defects of the existing technology. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and provide a door and window casing.

[0006] To meet the purpose of the utility model, the utility model adopts the following technical solutions:

[0007] A door and window casing for covering a door and window wall body, comprising: a plate body for covering the end surface of the door and window wall body and a fastening wall bent from one end of the plate body; the fastening wall is provided with a bayonet in the direction towards the other end of the plate body; the fastening wall is arranged to abut against the vertical surface of the door and window wall body.

[0008] Preferably, the inner side surface of the fastening wall extends towards the other end of the plate body to form a pair of extending walls, the ends of the pair of extending walls face each other to form two limiting walls, and the bayonet is formed between the two limiting walls.

[0009] More preferably, the end of the fastening wall away from the plate body extends towards the other end of the plate body to form an abutting wall. Optionally, the other end of the plate body forms a pair of plug-in plates spaced apart from each other by a certain distance.

[0010] Preferably, a wavy portion is formed on the inner surface of each plug-in board. Further preferably, the board body includes an outer wall and an inner wall arranged opposite to each other, and a support board for separating the outer wall and the inner wall is arranged between the outer wall and the inner wall.

[0011] Optionally, the fastening wall is formed by extending from one end of the board body in a direction from the outer wall towards the inner wall. Further optionally, one of the pair of extending walls partially overlaps with the inner wall.

[0012] Preferably, a gap is formed between the other extending wall of the pair of extending walls and the abutting wall. Further preferably, the height of the abutting wall relative to the fastening wall is greater than the height of the other extending wall relative to the fastening wall.

[0013] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0014] The door and window casing provided by the present utility model is jointly composed of an integrally formed board body and a fastening wall bent from one end of the board body. For a window wall or a door wall (hereinafter simply referred to as a door and window wall), it generally has an inner end face of the wall and a wall facade perpendicular to the inner end face of the wall. The board body has a certain length, such as a length consistent with the thickness of the building wall, so it can ensure that the board body completely covers the inner end face of the door and window wall, thereby covering the rough edges of the inner end face of the wall and forming a beautiful effect.

[0024] In the present utility model, the door and window casing is jointly composed of a plate body formed integrally and a fastening wall bent from one end of the plate body. For a window wall or a door wall (hereinafter simply referred to as a door and window wall), it generally has an inner end face of the wall and a wall facade perpendicular to the inner end face of the wall. The plate body has a certain length, which can ensure that the plate body completely covers the inner end face of the door and window wall, thereby covering the rough edges of the inner end face of the wall and forming a beautiful effect. The fastening wall abuts against the wall facade, thereby covering the transition part between the inner end face of the wall and the wall facade, which can also protect the wall corners from being damaged. The fastening wall can further enhance the stability of fixing the entire door and window casing to the door and window wall.

[0025] In one embodiment of the present utility model, referring to Figure 1 - 2c , a door and window casing 100 is provided for covering a door and window wall.

[0026] Specifically, in the field of building home decoration, for a building wall surface, it is usually necessary to make an opening in the wall surface to install a window or a door leaf. Usually, the inner end surface of the opening has rough edges left by construction. In order to cover the rough edges and to provide a window frame that serves as a basic framework for installing a window sash or a door leaf, it is necessary to install a door and window casing on the inner end surface of the opening, so as to cover the rough edges and improve the aesthetic appearance. Moreover, after the door and window casing covers the four inner end surfaces of the opening, an overall window frame is formed, which is used to further install a window sash or a door leaf on the basis of the window frame.

[0027] The door and window casing 100 includes a plate body 10 for covering the end surface of the door and window wall and a fastening wall 20 bent from one end of the plate body 10; the fastening wall 20 is provided with a bayonet 24 in the direction towards the other end of the plate body 10; the fastening wall 20 is arranged to abut against the vertical surface of the door and window wall.

[0028] For example, in the Figure 2a - 2c illustrated embodiment, an example of covering the door and window casing 100 on a wall 200 is shown. An opening (not labeled) is formed on the wall 200, the inner side of the opening of the wall 200 is the inner end surface 202 of the wall, and the surface of the wall 200 perpendicular to the inner end surface 202 of the wall is the wall vertical surface 204. As shown in the figure (also in combination with Figure 1 ), the plate body 10 covers the inner end surface 202 of the wall, and the fastening wall 20 covers and abuts against the wall vertical surface 204.

[0029] The plate body 10 has sufficient length, and for inner end surfaces of walls with different specifications and thicknesses, a variety of door and window casings 100 with different specifications can be designed. The door and window casings 100 with different specifications have plate bodies 10 with different lengths, so as to be able to adapt to different thicknesses of the inner end surfaces of the walls.

[0030] The fastening wall 20 and the plate body 10 can be integrally formed, thereby enhancing the structural strength of the entire door and window casing 100, reducing the overall deformation of the door and window casing 100, and further improving the installation stability. Since the fastening wall 20 covers the wall vertical surface 204, therefore, the corner part between the plate body 10 and the fastening wall 20 can protect the corner part of the wall between the inner end surface 202 of the wall and the wall vertical surface 204, and also improves the aesthetic appearance of the covered wall. In addition, the fastening wall 20 abuts against the wall vertical surface 204, so it can limit the offset and displacement of the plate body 10 on the inner end surface 202 of the wall, thereby ensuring the installation stability of the door and window casing 100.

[0031] In addition, the integrally formed plate body and the fastening wall also avoid the appearance of a large number of splicing gaps as in the prior art, thus greatly affecting the aesthetic degree of the overall structure.

[0032] Preferably, an inner side surface of the fastening wall 20 extends towards the other end of the plate body 10 to form a pair of extending walls 242, ends of the pair of extending walls 242 face each other to form two limiting walls 244, and a bayonet 24 is formed between the two limiting walls 244. The purpose of providing the bayonet 24 is to limit the 45-degree angle code. Specifically, since the wall opening has four inner end faces 202 of the wall body, and two adjacent inner end faces 202 of the wall body are perpendicular to each other, angle codes are needed to connect two window and door casings 100 that are perpendicular to each other. The angle code can be inserted into the bayonet 24, and the angle code is locked between the two window and door casings 100 by means of screws.

[0033] Preferably, one end of the fastening wall 20 away from the plate body 10 extends towards the other end of the plate body 10 to form an abutting wall 22. The abutting wall 22 is provided to abut against the wall body facade 204 so as to abut the entire fastening wall 20 against the wall body facade 204.

[0034] In addition, a pair of plug-in plates 18 spaced apart from each other by a certain distance can be formed at the other end of the plate body 10. A wavy portion 182 is formed on an inner surface of each plug-in plate 18. When the length of the plate body of the window and door casing 100 is smaller than the thickness of the inner end face 202 of the wall body, multiple window and door casings 100 need to be spliced together to be able to cover the entire inner end face 202 of the wall body. By inserting two ends of, for example, a fastening plate into a pair of plug-in plates 18 of corresponding window and door casings 100 respectively, the effect of connecting two window and door casings 100 by means of the fastening plate is achieved, and the depth at which the fastening plate is inserted into a corresponding pair of plug-in plates 18 of the corresponding window and door casing 100 is adjustable, so as to be applicable to inner end faces 202 of different thicknesses. The formation of the wavy portion 182 on the inner surface of the plug-in plate 18 can enhance the frictional force of the connection between the inner wall surface of the plug-in plate 18 and the fastening plate, thus ensuring stable connection and not being prone to slipping.

[0035] In one embodiment, the plate body 10 includes an outer wall 12 and an inner wall 14 arranged opposite to each other, and a support plate 16 separating the outer wall 12 and the inner wall 12 is arranged between the outer wall 12 and the inner wall 14. This setting increases the thickness of the entire plate body 10, thereby enhancing its structural stiffness, reducing its own deformation when installing a door leaf or a window sash, and at the same time, due to the adoption of a hollow structure (the two inner walls are arranged at intervals, and the support plate 16 is arranged between them), the weight of the entire window and door casing 100 is greatly reduced.

[0036] Preferably, the fastening wall 20 is formed by extending from one end of the plate body 10 in a direction from the outer wall 12 towards the inner wall 14. One of the pair of extension walls 242 partially overlaps with the inner wall 14. In addition, a gap is formed between the other extension wall 242 of the pair of extension walls 242 and the abutting wall 22. The existence of this gap greatly expands the operating space for installing the corner bracket, facilitating the construction personnel to use tools such as screwdrivers to fasten the corner bracket.

[0037] Optionally, the height of the abutting wall 22 relative to the fastening wall 20 is greater than the height of the other extension wall 242 relative to the fastening wall 20. This setting ensures that when the fastening wall 20 is wrapped around the wall facade 204, the corner bracket will not directly contact the wall facade 204, and provides sufficient operating space for installing the corner bracket, facilitating the construction personnel to fasten the corner bracket.

[0038] Those skilled in the art of the present technology can understand that the various operations, methods, steps, measures, and solutions in the processes discussed in this application can be alternated, changed, combined, or deleted. Further, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, changed, rearranged, decomposed, combined, or deleted. Further, those in the prior art having steps, measures, and solutions in the various operations, methods, and processes disclosed in this application can also be alternated, changed, rearranged, decomposed, combined, or deleted.

[0039] The above are only some embodiments of this application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this application.
