Description

Technical Field

[0001] The utility model relates to the technical field of casement windows, in particular to a fixing structure of a casement window. Background Technique

[0002] The casement window is a common window style in civil residential houses. The opening and closing of the window sash moves along a certain horizontal direction, so it is named "casement window". The casement window includes a window frame and a window sash. The common installation of the casement window is to first put the window frame into the wall hole, adjust the flatness and then fix and connect it with screws. After the fixation, cement slurry is injected into the gap between the wall and the window frame from the indoor side to fill it. Since the cement slurry is in a fluid state, referring to a hidden drainage casement window profile with the publication (announcement) number: CN215761365U, it can be seen that the connecting surface of the current casement window frame facing the wall hole does not have a structure for storing cement slurry, which easily causes the cement slurry to flow away during the process of filling the window frame with cement slurry, resulting in a sense of hollowness in some areas of the window frame after installation, affecting the user experience. Therefore, foaming glue is now mostly used instead of cement slurry, but its stability and reinforcement are not as good as those of cement. Therefore, how to make a window frame structure that can prevent the loss of cement slurry is an urgent problem to be solved in the industry. Content of the Utility Model

[0003] The utility model aims to provide a fixing structure of a casement window to prevent the loss of cement slurry during the process of filling the window frame.

[0004] To achieve the above object, the utility model provides the following technical solution: a fixing structure of a casement window, including a window frame, the window frame includes an outdoor profile, an indoor profile and a broken bridge glue. The front and rear sides of the outdoor profile protrude in the thickness direction to form a first surrounding edge, thereby forming a first accommodating groove. The front and rear sides of the indoor profile protrude in the thickness direction to form a second surrounding edge, thereby forming a second accommodating groove. At least one internal corner groove is provided at the bottom of the first accommodating groove and the second accommodating groove. The broken bridge glue is arranged at the cross-section between the indoor profile and the outdoor profile, and a third accommodating groove is arranged outside the broken bridge glue.

[0005] Further, the internal corner groove gradually inclines towards the outdoor side from its groove opening to the groove bottom.

[0006] Further, the height of the first surrounding edge on the side of the outdoor profile close to the indoor side is equal to the height of the second surrounding edge, and the height of the first surrounding edge on the side of the outdoor profile close to the outdoor side is higher than the height of the second surrounding edge.

[0007] Further, a first bending part extending towards the first accommodating groove is provided at the end of the first surrounding edge, and a second bending part extending towards the second accommodating groove is provided at the end of the second surrounding edge.

[0008] Furthermore, the broken bridge glue is disposed in the middle of the cross section.

[0009] Furthermore, a frosted surface is provided on the inner side of the third accommodation groove.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: the first accommodation groove, the second accommodation groove and the third accommodation groove provided can provide a larger accommodation cavity for accommodating cement slurry. At the same time, the provided internal angle groove can store the cement slurry. Moreover, after the cement slurry enters the internal angle groove, it will be resisted by the cement slurry in the first accommodation groove or the second accommodation groove at the notch of the internal angle groove, thereby preventing the loss of the cement slurry in the internal angle groove. And after drying, the concrete cement and the internal angle groove are hooked with each other, which can further improve the connection stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0017] As shown in the attached drawings, a fixed structure of a casement window of the present utility model includes a window frame 1. The window frame 1 includes an outdoor profile 11, an indoor profile 12, and a thermal break sealant 13. The front and rear sides of the outdoor profile 11 protrude in the thickness direction to form a first surrounding edge 14, thereby forming a first accommodation groove 140. The front and rear sides of the indoor profile 12 protrude in the thickness direction to form a second surrounding edge 15, thereby forming a second accommodation groove 150. At least one internal corner groove 145 is provided at the bottom of the first accommodation groove 140 and the second accommodation groove 150. The internal corner groove 145 gradually inclines towards the outdoor side from the groove opening to the groove bottom. The thermal break sealant 13 is disposed at the cross-section between the indoor profile 12 and the outdoor profile 11. A third accommodation groove 160 is provided outside the thermal break sealant 13. A sub-frame is also provided on the indoor profile 12 and the outdoor profile 11, and is connected to the window sash 33 / screen sash through the sub-frame.

[0018] A fixed structure of a casement window of the present utility model provides a larger accommodation cavity to accommodate the cement slurry 2 through the recessed first accommodation groove 140, second accommodation groove 150, and third accommodation groove 160 provided on the outside of the window frame 1. It should be noted that the overall width of the window frame 1 remains unchanged. The first accommodation groove 140 and the second accommodation groove 150 are realized by compressing the profile cavity, so that the window frame 1 has a larger space to accommodate the cement slurry 2. At the same time, the provided internal corner groove 145 can store the cement slurry 2. Since the workers mostly inject the cement slurry 2 from the indoor side, the internal corner groove 145 inclined towards the outdoor side is more conducive to the entry of the cement slurry 2. At the same time, the inclined opening design of the internal corner groove 145 can relieve part of the direct downward pressure of the internal cement slurry 2. Moreover, after the cement slurry 2 enters the internal corner groove 145, it will be blocked by the cement slurry 2 in the first accommodation groove 140 or the second accommodation groove 150 at the groove opening of the internal corner groove 145, thereby preventing the loss of the cement slurry 2 in the internal corner groove 145, thus achieving the effect of preventing the loss of the cement slurry 2. And after drying, the concrete cement and the internal corner groove are hooked to each other, which can further improve the connection stability. This structure is also applicable to the use of foaming sealant.

[0019] Reference Figure 2 , the internal corner groove 145 gradually inclines towards the outdoor side from its groove opening to the groove bottom. The cement slurry 2 is injected into the gap between the window frame 1 and the window opening from the indoor side towards the outdoor side. The special inclination structure is beneficial to the entry of the cement slurry 2 and makes it difficult for the cement slurry 2 entering the internal corner groove 145 to flow out. The internal corner groove 145 structure in the shape of Figure 4 can also be adopted, which can better prevent the cement slurry 2 entering the interior from flowing out, but the production grooving process is relatively complex.

[0020] In this embodiment, the height of the first perimeter 14 on the side of the outdoor profile 11 close to the interior is equal to the height of the second perimeter 15, and the height of the first perimeter 14 on the side of the outdoor profile 11 close to the exterior is higher than the height of the second perimeter 15, which means that the first perimeter 14 of the outdoor profile 11 on the side close to the exterior protrudes beyond the other baffles, which is more conducive to blocking the cement slurry 2 from flowing out from the exterior. At the same time, during the installation of the window frame 1, it is necessary to first place the window frame 1 into the wall hole and level it by using spacers. The spacers mainly play a role in positioning the window frame 1 during the leveling and fixing of the window frame 1. The spacers are inserted into the gap from the interior side, and the protruding first perimeter 14 can abut against the spacers to prevent the spacers from protruding beyond the exterior, thereby preventing the risk of the spacers falling out of the exterior.

[0021] In this embodiment, a first bending portion 144 extending towards the first accommodating groove 140 is provided at the end of the first perimeter 14, and a second bending portion 155 extending towards the second accommodating groove 150 is provided at the end of the second perimeter 15, which is more conducive to blocking the loss of the cement slurry 2.

[0022] In this embodiment, the broken bridge sealant 13 is provided in the middle of the cross-section. It should be noted that the existing broken bridge sealants 13 are both provided in two, respectively provided on both sides in the height direction of the cross-section to disconnect the connection between the profiles, and the two broken bridge sealants 13 cooperate with the interior profile 12 and the outdoor profile 11 to form a heat insulation cavity. Now, the broken bridge sealant 13 located on the outer side is moved to the middle of the cross-section to form a third accommodating groove 160; a frosted surface 131 is provided inside the third accommodating groove 160, which can increase the adhesion of the cement slurry 2.

[0023] The above embodiments are the preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made thereto shall fall within the protection scope of the present invention.
