Description

Technical Field

[0001] The utility model belongs to the technical field of door and window frames, and in particular relates to a spliced ​​door and window frame structure. Background Art

[0002] As people's requirements for building lighting increase, the window designs in building doors and windows are getting bigger and bigger. In order to increase the area of ​​doors and windows, the industry often uses two door and window frames to splice. At present, there are two main ways to splice two door and window frames. One way is to add a thermal break frame material between the two door and window frames. This method has a simple structure, but the visible surface of the thermal break frame material is too wide, and the length of the screws required for connection is long, which affects the stability. At the same time, there are also problems of wasting materials and difficult positioning and assembly. Another way is to use frame strips for splicing, but the existing frame strip structure has the problem of poor sealing performance. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0026] Example 1

[0027] like Figures 1 to 4 As shown, this embodiment designs a spliced ​​door and window frame structure, including a left window frame 2, a right window frame 1, an outer splicing strip 4 and an inner splicing strip 5 and other components.

[0028] The left window frame 2 is spliced ​​to the left side of the right window frame 1, and the left window frame 2 and the right window frame 1 are placed side by side. The high-strength screws passing through the left window frame 2 and the right window frame 1 can tighten the two together. The gap formed between the left window frame 2 and the right window frame 1 is the splicing seam. Since in the structure of this embodiment, there is no need to install a thermal insulation frame material at the splicing seam, the distance between the left window frame 2 and the right window frame 1 can be effectively reduced, thereby improving the stability after splicing.

[0029] The outer splicing strip 4 is installed on the outdoor side of the splicing seam, the inner side of the outer splicing strip 4 extends into the splicing seam and is fixedly connected to the left window frame 2 or the right window frame 1; the outer side of the outer splicing strip 4 extends out of the splicing seam, the part of the outer splicing strip 4 extending to the left is abutted against the outer side surface of the left window frame 2 through the first sealing strip 3, and the part of the outer side of the splicing strip extending to the right is abutted against the outer side surface of the right window frame 1 through the second sealing strip 6.

[0030] Specifically: the outer splicing strip 4 includes two main parts, an L-shaped strip portion 41 and a T-shaped strip portion; wherein the cross-section of the T-shaped strip portion is T-shaped, and the cross-section of the L-shaped strip portion 41 is L-shaped, as shown in the accompanying drawings; the outer side of the longitudinal part of the T-shaped strip portion is connected to the middle part of the transverse part of the T-shaped strip portion, and the inner side of the longitudinal part of the T-shaped strip portion is connected to the middle part of the transverse part of the L-shaped strip portion 41; the longitudinal part of the L-shaped strip portion 41 is connected to the left window frame 2 or the right window frame 1, and the L-shaped strip portion 41 can be connected to the left window frame 2 or the right window frame 1 by screws, thereby realizing the installation and fixation of the outer splicing strip 4.

[0031] The left and right sides of the transverse part of the T-shaped strip portion are bent inward, that is, the left half and the right half of the transverse part are respectively bent in the direction of the L-shaped strip portion 41 to form an arc shape, thereby forming two sealing strip installation grooves 421 between the transverse part of the T-shaped strip portion and the longitudinal part of the T-shaped strip portion; the first sealing strip 3 and the second sealing strip 6 are respectively installed in the two sealing strip installation grooves 421, and the two sealing strip installation grooves 421 can limit the first sealing strip 3 and the second sealing strip 6 to ensure that the first sealing strip 3 and the second sealing strip 6 can be pressed onto the left window frame 2 and the right window frame 1.

[0032] An L-shaped curved edge 11 is respectively arranged at the left outer edge of the right window frame 1 and the right outer edge of the left window frame 2. The transverse portion of the L-shaped curved edge 11 is flush with the outer side surface of the left window frame 2 or the right window frame 1. The longitudinal portion of the L-shaped curved edge 11 is perpendicular to the outer side surface of the left window frame 2 or the right window frame 1. The free end of the L-shaped curved edge 11 (i.e., the inner side edge of the longitudinal portion of the L-shaped curved edge 11) is arranged with a first inclined surface 111. The transverse portion of the L-shaped strip portion 41 is arranged with a second inclined surface 411. Two second inclined surfaces 411 are respectively provided on the left and right sides of the portion; the first inclined surface 111 of the left window frame 2 and the second inclined surface 411 on the left side cooperate with each other, and the first inclined surface 111 of the right window frame 1 and the second inclined surface 411 on the right side cooperate with each other, so that when the left window frame 2 and the right window frame 1 are brought close to each other, the outer splicing strip 4 is driven to move toward the inner side of the splicing seam room, so that the T-shaped strip portion of the outer splicing strip 4 presses the first sealing strip 3 and the second sealing strip 6 to the outer sides of the left window frame 2 and the right window frame 1.

[0033] The inner splicing strip 5 is installed on the indoor side of the splicing seam. The inner splicing strip 5 is T-shaped as a whole. The inner side of the inner splicing strip 5 extends to the left and right directions respectively, and blocks the inner side surfaces of the left window frame 2 and the right window frame 1; the outer side of the inner splicing strip 5 extends into the splicing seam and is fixedly connected to the left window frame 2 or the right window frame 1.

[0034] Specifically, the inner splicing strip 5 includes a Z-shaped strip portion 51 and a flat strip portion 52; the inner side of the Z-shaped strip portion 51 is vertically connected to the middle of the flat strip portion 52; the outer side of the Z-shaped strip portion 51 extends into the splicing seam and is connected to the left window frame 2 or the right window frame 1 by screws.

[0035] The left side edge of the flat strip portion 52 extends to the left edge of the inner side surface of the left window frame 2, and the right side edge of the flat strip portion 52 extends to the right edge of the inner side surface of the right window frame 1, so that the left and right sides of the flat strip portion 52 are used to respectively cover the inner side surfaces of the left window frame 2 and the right window frame 1.

[0036] The left and right edges of the flat strip portion 52 are processed into a third bevel 521, and the third bevel 521 is used for chamfering the left and right sides of the flat strip portion 52. The flat strip portion 52 is not only used to shield the joint seam and the inner side surfaces of the left window frame 2 and the right window frame 1, but also can reduce the sharp edges on the flat strip portion 52 to avoid scratching the user.

[0037] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
