Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and particularly provides a load-bearing structure for door and window glass and a door and window comprising the load-bearing structure for door and window glass. Background Art

[0002] Currently, doors and windows mainly include a door and window frame and door and window glass installed in the door and window frame. The door and window frame is mainly composed of a left profile, a right profile, an upper profile and a lower profile. In a door and window system, the heat insulation performance and load-bearing capacity of the door and window frame are very important. In order to improve the heat insulation performance of the door and window frame, the left profile, the right profile, the upper profile and the lower profile of the door and window frame all adopt broken bridge aluminum profiles. Then, the left profile, the right profile, the upper profile and the lower profile of the door and window frame all include an indoor profile, an outdoor profile and a heat insulation material connected between the indoor profile and the outdoor profile. At the same time, in order to improve the glass load-bearing capacity of the door and window frame, a support plate component is arranged in the door and window frame to abut against directly below the door and window glass; for example, a profile and a glass fan body disclosed in a Chinese utility model patent with the authorization publication number of CN214365651U is provided with a glass body support plate directly below the door and window glass. However, the prior art has the following defects:

[0003] 1. After the glass body support plate is installed in the indoor profile of the lower profile, there is a gap between the glass body support plate and the indoor profile. Thus, after the door and window glass is installed subsequently, under the dual action of the glass body support plate bearing the gravity of the door and window glass and the gap between the glass body support plate and the indoor profile, it is easy to cause the free end of the glass body support plate away from the indoor profile to sag and lap with the outdoor profile of the lower profile, resulting in heat transfer, thereby causing a bad phenomenon of bridging between the indoor profile and the outdoor profile of the lower profile, damaging the heat insulation effect of the lower profile, and finally damaging the overall heat insulation performance of the door and window frame.

[0004] 2. Since the door and window glass cannot be in direct contact with the glass body support plate of the aluminum profile, glass pads need to be placed on the top surface of the glass body support plate first when installing the door and window glass. The glass pads are separated between the bottom surface of the door and window glass and the top surface of the glass body support plate. However, the glass pads are only placed on the top surface of the glass body support plate, and there is no other connection relationship between the two; thus, before and during the installation of the door and window glass, the glass pads and the glass body support plate are very likely to move relatively, thereby changing the force distribution of the glass body support plate after the door and window glass is installed and affecting the overall load-bearing effect of the door and window frame. Summary of the Utility Model

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a load-bearing structure for door and window glass, which can effectively avoid the formation of an indoor-outdoor bridge in the lower profile due to the overlap between the glass load-bearing component and the non-contact material (i.e., the indoor profile or the outdoor profile that does not contact the glass load-bearing component) in the lower profile.

[0006] To achieve the above purpose, the present utility model provides a load-bearing structure for door and window glass, including a lower profile and a glass load-bearing component, both of which are used for assembling at the lower end of the door and window glass. The lower profile includes an indoor profile, a heat insulation material, and an outdoor profile that are sequentially connected in the indoor-outdoor direction. One of the indoor profile and the outdoor profile is a load-bearing fixing material for fixedly installing the glass load-bearing component, and the other is a non-contact material that does not contact the glass load-bearing component. The glass load-bearing component includes a load-bearing main body for carrying the door and window glass, and a limit installation part fixedly arranged on one end side of the load-bearing main body facing the load-bearing fixing material. The limit installation part includes an installation main body part, a first limit protrusion protruding from the outer periphery of the installation main body part towards the load-bearing fixing material, and a second limit protrusion protruding upwards from the top of the installation main body part.

[0007] The load-bearing fixing material includes a side profile main body located on the outer peripheral side of the limit installation part, a bottom profile main body located on the lower side of the limit installation part, and profile hooks fixed to the side profile main body and distributed above the bottom profile main body. An installation groove and an installation opening located at one end of the installation groove facing away from the side profile main body are formed between the side profile main body, the bottom profile main body, and the profile hooks.

[0008] After the end of the limit installation part away from the load-bearing main body is inserted into the installation groove, one end of the first limit protrusion facing away from the load-bearing main body abuts against the outer wall surface of the side profile main body, one end of the second limit protrusion facing the load-bearing main body abuts against the inner wall surface of the profile hook, and the bottom of the installation main body part abuts against the outer wall surface of the bottom profile main body. A gap is formed between the glass load-bearing component and the heat insulation material and the non-contact material.

[0009] The lower profile in the present application is a thermally-broken profile, and the door and window glass load-bearing structure is a glass support structure for the thermally-broken profile to support the door and window glass. In the door and window glass load-bearing structure involved in the present application, the glass load-bearing component is installed as a whole on the load-bearing fixing material by installing the limiting mounting part on the load-bearing fixing material, thereby realizing the fixed installation of the glass load-bearing component in the lower profile. In particular, after the limiting mounting portion of the glass load-bearing component is installed into the mounting groove of the load-bearing fixing material, three-point limiting is achieved through the abutment and cooperation between the first limiting protrusion and the side profile body, the abutment and cooperation between the second limiting protrusion and the profile hook, and the abutment and cooperation between the mounting body and the bottom profile body, thereby restricting the movement of the glass load-bearing component in the indoor and outdoor directions and downward movement; and after the door and window glass is installed, the glass load-bearing component bears the gravity of the door and window glass, and through the abutment and cooperation between the first limiting protrusion and the side profile body, the abutment and cooperation between the second limiting protrusion and the profile hook, and the abutment and cooperation between the mounting body and the bottom profile body, thereby restricting the movement of the glass load-bearing component in the indoor and outdoor directions and downward movement, and reliably transmitting the gravity of the door and window glass to the load-bearing fixing material. Therefore, in the present application, when the glass load-bearing components are installed, and when and after the door and window glass is installed, the glass load-bearing components will not move relative to the load-bearing fixing materials; on the one hand, it is reliably ensured that the glass load-bearing components are always suspended above the thermal insulation material and the non-contact material, effectively avoiding the load-bearing main body of the glass load-bearing components from overlapping with the non-contact material and / or the thermal insulation material of the lower profile due to offset, thereby effectively avoiding the connection of the broken bridge profile constituting the lower profile, ensuring the thermal insulation performance of the lower profile, and thus ensuring the thermal insulation performance of the doors and windows; on the other hand, it is reliably ensured that the glass load-bearing components are optimally distributed, ultimately making the force on the lower profile reasonable, thereby ensuring the load-bearing capacity of the lower profile.

[0010] Furthermore, the first limiting protrusion is provided with a first limiting plane at one end facing away from the load-bearing main body, and the first limiting plane is in surface-to-surface contact with the outer wall of the side profile body; the second limiting protrusion is provided with a second limiting plane at one end facing the load-bearing main body, and the second limiting plane is in surface-to-surface contact with the inner wall of the profile hook; the bottom of the installation main body is provided with a third limiting plane, and the third limiting plane is in surface-to-surface contact with the outer wall of the bottom profile body. In this way, the first limiting protrusion and the side profile body, the second limiting protrusion and the profile hook, and the installation main body and the bottom profile body are all in surface contact, with a larger contact area, which can more reliably constrain the movement of the glass load-bearing components, and enable the glass load-bearing components to more reliably transfer the gravity of the door and window glass to the lower profile, ultimately effectively improving the rationality of the force of the doors and windows as a whole, and extending the service life of the doors and windows as a whole.

[0011] Furthermore, an inclined surface is provided on the bottom surface of the glass load-bearing member. The inclined surface covers the bottom surface of the load-bearing main body portion and a part of the bottom surface of the installation main body portion. The inclined surface is inclined in such a way that it slopes upward as it is farther away from the load-bearing fixing material. The inclined surface forms a gap between the glass load-bearing member and the heat insulation material and the non-contact material. In this way, the suspended structure of the glass load-bearing member relative to the heat insulation material and the non-contact material is simplified, and the production cost of the glass load-bearing member is reduced.

[0012] Furthermore, the installation opening allows the first limiting protrusion and the second limiting protrusion to enter the installation groove from one side of the installation groove. Based on this, when the end of the limiting installation portion away from the load-bearing main body portion is inserted into the installation groove, first make the end of the second limiting protrusion away from the load-bearing main body portion snap into the installation groove through the installation opening, and then rotate the end of the glass load-bearing member away from the load-bearing fixing material downward. During this process, the first limiting protrusion snaps into the installation groove through the installation opening until the limiting installation portion is installed in place in the installation groove; after the end of the limiting installation portion away from the load-bearing main body portion is inserted into the installation groove, the first limiting protrusion, the second limiting protrusion, and a part of the installation main body portion are all accommodated in the installation groove, and the installation main body portion passes through the installation opening. Therefore, when installing the glass load-bearing member in this application, the glass load-bearing member is installed on the load-bearing fixing material in a rotating manner. While rotating the glass load-bearing member downward, the end of the limiting installation portion away from the load-bearing main body portion snaps into the installation groove through the installation opening. Then, during the installation process of the glass load-bearing member, the load-bearing main body portion of the glass load-bearing member gradually moves downward closer to the non-contact material and the heat insulation material, more effectively avoiding the overlap of the load-bearing main body portion with the non-contact material and / or the heat insulation material during the installation of the glass load-bearing member, and avoiding the lower profile connecting bridge.

[0013] Furthermore, a limiting component is provided between the limiting installation portion and the load-bearing fixing material; after the end of the limiting installation portion away from the load-bearing main body portion is inserted into the installation groove, the limiting component restricts the movement of the limiting installation portion relative to the load-bearing fixing material. The preferred structure of the limiting component is: the limiting component includes a first connection hole opened in the installation main body portion, a second connection hole opened in the bottom profile main body, and a limiting member, and the limiting member is fixed in the first connection hole and the second connection hole. The glass load-bearing member is more reliably restricted from shifting after being installed on the load-bearing fixing material through the limiting component, ensuring that the glass load-bearing member will not move relative to the load-bearing fixing material during and after the subsequent installation of the door and window glass, guaranteeing the initial force distribution and ensuring the reasonable force-bearing of the lower profile.

[0014] Preferably, the first connection hole is a counterbore, and the limiting member is a countersunk head limiting component, avoiding the upper end of the limiting member being higher than the top surface of the installation main body portion, so that the limiting member will not interfere with the subsequent installation of the door and window glass.

[0015] Further, the glass load-bearing member is an integrally formed aluminum profile, which facilitates the production of the glass load-bearing member and also endows the glass load-bearing member with good structural strength.

[0016] Further, the door and window glass load-bearing structure further includes a glass cushion block, which is arranged on the top surface of the load-bearing main body and fixedly connected to the load-bearing main body. By providing the glass cushion block, direct contact between the door and window glass and the glass load-bearing member of the aluminum profile is avoided; in particular, since the glass cushion block is fixedly connected to the load-bearing main body, the glass cushion block will not shift relative to the load-bearing main body of the glass load-bearing member during and after the installation of the door and window glass, and thus the force distribution of the glass load-bearing member after the installation of the door and window glass will not be changed, reliably ensuring the rationality of the force on the lower profile.

[0017] Preferably, the glass cushion block is a self-adhesive cushion block, and the glass cushion block is adhesively fixed to the load-bearing main body, which facilitates the fixed installation of the glass cushion block and reduces costs.

[0018] The present application provides a door and window, which can be a non-openable fixed door and window or an openable opening and closing door and window. When the door and window is a fixed door and window, the door and window includes a fixedly arranged fixed outer frame, door and window glass fixed to the fixed outer frame, and the door and window glass load-bearing structure as described above. The door and window glass load-bearing structure is arranged between the lower end of the door and window glass and the fixed outer frame, and the lower profile in the door and window glass load-bearing structure is the profile assembled at the lower end of the door and window glass in the fixed outer frame. When the door and window is an opening and closing door and window, the door and window includes a fixedly arranged fixed outer frame, a door and window sash movably installed in the fixed outer frame, and the door and window glass load-bearing structure as described above. The door and window sash includes a sash frame and door and window glass fixed to the sash frame. The door and window glass load-bearing structure is arranged between the lower end of the door and window glass in the door and window sash and the sash frame, and the lower profile in the door and window glass load-bearing structure is the profile assembled at the lower end of the door and window glass in the sash frame.

[0019] As described above, a door and window glass load-bearing structure and a door and window according to the present utility model have the following beneficial effects:

[0020] During the installation of the glass load-bearing component and during and after the installation of the door and window glass, the glass load-bearing component will not move relative to the load-bearing fixed material through the abutment and cooperation between the first limiting protrusion and the side profile body, the abutment and cooperation between the second limiting protrusion and the profile hook, and the abutment and cooperation between the installation body and the bottom profile body. On the one hand, it is reliably ensured that the glass load-bearing component is always suspended above the heat-insulating material and the non-contact material, and the load-bearing body of the glass load-bearing component is effectively prevented from overlapping with the non-contact material and / or the heat-insulating material of the lower profile due to offset, thereby effectively avoiding the connection of the broken bridge profile constituting the lower profile, ensuring the thermal insulation performance of the lower profile, and thus ensuring the thermal insulation performance of the doors and windows. On the other hand, it is reliably ensured that the glass load-bearing component is optimally distributed, and finally the force on the lower profile is reasonable, ensuring the load-bearing capacity of the lower profile.

When an element is referred to as "connected to" another element, it can be directly connected to the other element or it can also be indirectly connected to the other element through an intermediate element.

[0066] In addition, in this application, the descriptions involving "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0067] This application provides a load-bearing structure for door and window glass, and a door and window configured with this load-bearing structure for door and window glass.

[0068] For the convenience of narration, in the following embodiments, the definitions of each direction are as follows: the width direction of the door and window is defined as the left-right direction, the height direction of the door and window is defined as the up-down direction, the thickness direction of the door and window is defined as the front-back direction, the thickness direction of the door and window is also the indoor-outdoor direction, and the outdoor side direction is the front direction, and the indoor side direction is the back direction. Based on this, Figure 1 and Figure 11In the views shown, the left and right sides of the paper surface are the front direction and the rear direction respectively, the upper and lower sides of the paper surface are the upward direction and the downward direction respectively, and the front and back sides of the paper surface are the left direction and the right direction respectively.

[0069] As Figure 1 shown, or as Figure 11 shown, the window and door glass load-bearing structure involved in the present utility model includes a lower profile 20 and a glass load-bearing member 30 both for being assembled at the lower end of the window and door glass 10. The length directions of the lower profile 20 and the glass load-bearing member 30 are consistent with the width direction of the window and door, both being the left-right direction. The lower profile 20 is a broken bridge profile, and then the window and door glass load-bearing structure is a glass support structure for supporting the window and door glass 10 with the broken bridge profile. The broken bridge profile forming the lower profile 20 includes an indoor profile 23 distributed at the rear side, an outdoor profile 22 distributed at the front side, and a heat insulation material 21 fixedly embedded between the indoor profile 23 and the outdoor profile 22; the heat insulation material 21 is preferably a PK material, and the indoor profile 23 and the outdoor profile 22 are preferably both integrally formed aluminum profiles.

[0070] Furthermore, among the indoor profile 23 and the outdoor profile 22, one is a load-bearing fixing material 40 for fixedly installing the glass load-bearing member 30, and the other is a non-contact material 110 that does not contact the glass load-bearing member 30. In this way, the window and door glass load-bearing structure has two embodiments. In the first embodiment of the window and door glass load-bearing structure, as Figure 1 shown, the glass load-bearing member 30 is fixed to the indoor profile 23 and does not contact the outdoor profile 22. At this time, the indoor profile 23 constitutes the load-bearing fixing material 40, and the outdoor profile 22 constitutes the non-contact material 110. In the second embodiment of the window and door glass load-bearing structure, as Figure 11 shown, the glass load-bearing member 30 is fixed to the outdoor profile 22 and does not contact the indoor profile 23. At this time, the outdoor profile 22 constitutes the load-bearing fixing material 40, and the indoor profile 23 constitutes the non-contact material 110. The first embodiment of the window and door glass load-bearing structure and the second embodiment of the window and door glass load-bearing structure are front-back mirror images. The following takes the first embodiment of the window and door glass load-bearing structure as an example to describe the preferred structures of the lower profile 20 and the glass load-bearing member 30.

[0071] As Figure 1 、 Figure 6e and Figure 7eAs shown, the glass load-bearing member 30 includes a load-bearing main body portion 31 and a limit installation portion 32 fixedly provided on the indoor side (i.e., the rear side) of the load-bearing main body portion 31. Among them, the door and window glass 10 is installed above the load-bearing main body portion 31, and the load-bearing main body portion 31 bears the door and window glass 10. The top surface of the load-bearing main body portion 31 is a horizontal plane. The limit installation portion 32 is installed on the indoor side profile 23, thereby installing the glass load-bearing member 30 as a whole on the indoor side profile 23. Or rather, the glass load-bearing member 30 is fixedly installed as a whole in the lower side profile 20.

[0072] In particular, as Figure 1 shown, the indoor side profile 23 (i.e., the load-bearing fixing material 40) includes a side profile main body 41 located on the indoor side (i.e., the rear side) of the limit installation portion 32, a bottom profile main body 42 located below the limit installation portion 32, and a profile hook portion 43 fixedly provided on the outdoor side (i.e., the front side) of the side profile main body 41. The profile hook portion 43 is generally in an inverted L shape, having a horizontal section extending forward horizontally from the front wall surface of the side profile main body 41 and a vertical section extending vertically downward from the front end of the horizontal section. The vertical section is suspended above the bottom profile main body 42. Thus, an installation groove 44 and an installation opening 45 located at the outdoor side end (i.e., the front end) of the installation groove 44 are formed between the side profile main body 41, the bottom profile main body 42, and the profile hook portion 43. That is, the installation groove 44 is formed on the front side of the side profile main body 41, the upper side of the bottom profile main body 42, and the inner peripheral side of the profile hook portion 43, and the installation opening 45 is formed between the vertical section of the profile hook portion 43 and the bottom profile main body 42. As Figures 2 to 5 shown, the limit installation portion 32 includes an installation main body portion 321, a first limit protrusion 322 protruding backward toward the indoor from the indoor side of the installation main body portion 321, and a second limit protrusion 323 protruding upward from the top of the installation main body portion 321.

[0073] When installing the glass load-bearing member 30 on the indoor side profile 23, the indoor side end (i.e., the rear end) of the limit installation portion 32 is inserted into the installation groove 44 of the indoor side profile 23. When the indoor side end of the limit installation portion 32 is inserted into the installation groove 44 and is installed in place, as Figure 1As shown, the first limiting protrusion 322, the second limiting protrusion 323, and the rear end of the installation body 321 are all accommodated in the installation groove 44, and the installation body 321 is simultaneously penetrated in the installation opening 45; in particular, the indoor side end (i.e., the rear end) of the first limiting protrusion 322 and the front side outer wall surface of the side profile body 41, the outdoor side end (i.e., the front end) of the second limiting protrusion 323 and the inner wall surface of the profile hook 43 (i.e., the rear wall surface of the vertical section), and The bottom of the installation body 321 is in contact with the upper outer wall of the bottom profile body 42, and the glass load-bearing component 30 (i.e., the front section of the load-bearing body 31 and the installation body 321) located directly above the heat insulating material 21 and the outdoor profile 22 (i.e., the non-contact material 110) is suspended above the heat insulating material 21 and the outdoor profile 22, so that a gap 90 is formed between the glass load-bearing component 30 and the heat insulating material 21 and the outdoor profile 22. The outer wall of the side profile body 41 in contact with the rear end of the first limiting protrusion 322 and the inner wall of the profile hook 43 in contact with the front end of the second limiting protrusion 323 are both groove wall surfaces of the installation groove 44.

[0074] In the door and window glass load-bearing structure of the utility model, after the glass load-bearing component 30 is installed on the indoor side profile 23, three-point limiting is achieved through the abutment and cooperation between the rear end of the first limiting protrusion 322 and the side profile body 41, the abutment and cooperation between the front end of the second limiting protrusion 323 and the profile hook 43, and the abutment and cooperation between the lower end of the installation body 321 and the bottom side profile body 42. In this way, after the glass load-bearing component 30 is installed, and when and after the subsequent door and window glass 10 is installed, the three-point limiting structure between the rear end of the glass load-bearing component 30 and the indoor side profile 23 effectively restricts the forward and backward movement of the glass load-bearing component 30 in the indoor and outdoor directions, and restricts the downward movement of the glass load-bearing component 30, so that the glass load-bearing component 30 will not move relative to the indoor side profile 23. Based on this, on the one hand, it is reliably ensured that the load-bearing main body 31 and the partial installation main body 321 of the glass load-bearing component 30 are always suspended above the heat insulating material 21 and the outdoor profile 22, and there is a gap 90 between the glass load-bearing component 30 and the heat insulating material 21 and the outdoor profile 22, and none of them are in contact or overlapped. In particular, it is effectively avoided that the load-bearing main body 31 of the glass load-bearing component 30 is offset and overlapped with the outdoor profile 22 and / or the heat insulating material 21 of the lower profile 20, thereby effectively avoiding the thermal insulation profile bridge constituting the lower profile 20, ensuring the thermal insulation performance of the lower profile 20, and also ensuring the thermal insulation performance of the doors and windows; on the other hand, the glass load-bearing component 30 reliably transfers the gravity of the door and window glass 10 to the indoor profile 23, avoiding the change of its force distribution due to the offset of the glass load-bearing component 30, thereby ensuring the optimal force distribution of the glass load-bearing component 30, making the force on the lower profile 20 reasonable, and ensuring the bearing capacity of the lower profile 20.

[0075] Obviously, the load-bearing structure of the door and window glass involved in the present application effectively ensures the best heat preservation performance of the lower profile 20, effectively reduces the heat flow loss of the lower profile 20, and is conducive to the promotion of energy conservation and environmental protection. At the same time, it reliably ensures the overall energy-saving effect of the doors and windows. Under the condition of certain energy consumption, the overall size and area of the doors and windows can be enlarged, thereby expanding the indoor vision and lighting, and enhancing the commercial competitiveness of the doors and windows. Moreover, the load-bearing structure of the door and window glass involved in the present application also effectively ensures the best load-bearing effect of the lower profile 20, improves the force rationality of the overall doors and windows, and extends the service life of the overall doors and windows.

[0076] Further, as Figures 2 to 5 shown, a first limiting plane 324 is provided at the rear end of the first limiting protrusion 322, and the first limiting plane 324 is in surface contact with the front outer wall surface of the side profile main body 41. A second limiting plane 325 is provided at the front end of the second limiting protrusion 323, and the second limiting plane 325 is in surface contact with the inner wall surface of the profile hook portion 43. A third limiting plane 326 is provided at the bottom of the installation main body portion 321, and the third limiting plane 326 is in surface contact with the upper outer wall surface of the bottom profile main body 42. In this way, the first limiting protrusion 322 and the side profile main body 41, the second limiting protrusion 323 and the profile hook portion 43, and the installation main body portion 321 and the bottom profile main body 42 are all in surface contact and cooperation, having a large contact area, more reliably restricting the forward and backward movement and downward movement of the glass load-bearing member 30, avoiding bridging, and at the same time enabling the glass load-bearing member 30 to more reliably transfer the gravity of the door and window glass 10 to the indoor profile 23, ultimately effectively improving the overall heat preservation performance and force rationality of the doors and windows, and extending the service life of the overall doors and windows.

[0077] Preferably, as Figures 2 to 5 shown, the length directions of the first limiting protrusion 322 and the second limiting protrusion 323 are the same as the length direction of the glass load-bearing member 30, and the lengths are equal. At the same time, the length directions of the first limiting plane 324, the second limiting plane 325 and the third limiting plane 326 are also the same as the length direction of the glass load-bearing member 30, and the lengths are also equal. In this way, the first limiting protrusion 322, the second limiting protrusion 323, the first limiting plane 324, the second limiting plane 325 and the third limiting plane 326 are continuous extension structures in the length direction of the glass load-bearing member 30, improving the reliability of the surface contact and cooperation between the first limiting protrusion 322 and the side profile main body 41, the second limiting protrusion 323 and the profile hook portion 43, and the installation main body portion 321 and the bottom profile main body 42, and thus improving the limiting and stopping effect after the glass load-bearing member 30 is installed in place.

[0078] Preferably, as Figures 2 to 5As shown, the first limiting plane 324, the second limiting plane 325 and the third limiting plane 326 are triangularly distributed. After the glass bearing member 30 is installed in place, the abutting and mating points of the first limiting protrusion 322 and the side profile body 41, the abutting and mating points of the second limiting protrusion 323 and the profile hook portion 43, and the abutting and mating points of the installation main body portion 321 and the bottom profile body 42 are also triangularly distributed, ensuring the limiting effect on the glass bearing member 30.

[0079] Preferably, the glass bearing member 30 is an integrally formed part and is an aluminum profile, which facilitates the production of the glass bearing member 30 and also enables the glass bearing member 30 to have good structural strength. Of course, in other embodiments, the glass bearing member 30 can also be a stainless steel profile.

[0080] Further, the installation opening 45 of the indoor profile 23 allows the first limiting protrusion 322 and the second limiting protrusion 323 of the glass bearing member 30 to enter the installation groove 44 from the outdoor side of the installation groove 44. Based on this, when the indoor side end of the limiting installation portion 32 is inserted into the installation groove 44, as Figure 6a and Figure 6b 、 Figure 7a and Figure 7b 、as well as Figure 8 shown, the second limiting protrusion 323 and the first limiting protrusion 322 are successively snapped into the installation groove 44 through the installation opening 45, realizing the front-side rotational installation of the glass bearing member 30 into the installation groove 44 of the indoor profile 23. Specifically, as Figure 6a and Figure 7a shown, first, the glass bearing member 30 is placed at a relatively large inclination angle, and the second limiting protrusion 323 is snapped into the installation groove 44 through the installation opening 45; then, the front end of the glass bearing member 30 is rotated downward. During this process, as Figure 6b 、 Figure 7b and Figure 8As shown, the second limiting protrusion 323 gradually approaches the rear wall surface of the vertical section in the profile hook portion 43, and the first limiting protrusion 322 is snapped into the installation groove 44 through the installation opening 45 and gradually approaches the front wall surface of the side profile main body 41. Until the second limiting plane 325 at the front end of the second limiting protrusion 323 abuts against the inner wall surface of the profile hook portion 43, the rear end of the limiting installation portion 32 is completely embedded in the installation groove 44, and the limiting installation portion 32 is installed in place in the installation groove 44. At this time, the first limiting plane 324 at the rear end of the first limiting protrusion 322 just abuts against the front wall surface of the side profile main body 41, and the third limiting plane 326 at the lower end of the installation main body portion 321 just abuts against the upper wall surface of the bottom profile main body 42. Since the glass load-bearing member 30 is installed on the indoor profile 23 in a rotating manner, while rotating the glass load-bearing member 30 downward, the indoor side end of the limiting installation portion 32 is snapped into the installation groove 44 through the installation opening 45. Then, during the installation process of the glass load-bearing member 30, the load-bearing main body portion 31 of the glass load-bearing member 30 gradually approaches the outdoor profile 22 and the heat insulation material 21 downward, more effectively avoiding the overlap of the load-bearing main body portion 31 with the outdoor profile 22 and / or the heat insulation material 21 during the installation of the glass load-bearing member 30, and avoiding the bridging of the lower profile 20.

[0081] Furthermore, as Figure 2 , Figure 4 and Figure 5 shown, the bottom surface of the glass load-bearing member 30 is provided with an inclined surface 33. The inclined surface 33 covers the entire bottom surface of the load-bearing main body portion 31 and a part of the front bottom surface of the installation main body portion 321, that is: the front end of the inclined surface 33 extends forward to the front end of the bottom of the load-bearing main body portion 31, and the rear end of the inclined surface 33 extends backward to the front end of the third limiting plane 326 at the bottom of the installation main body portion 321. The inclined surface 33 is inclined in a manner that the farther away from the indoor profile 23, the higher it is, or rather, the inclined surface 33 is inclined forward and upward. The setting of the inclined surface 33 creates a gap 90 between the glass load-bearing member 30 and the heat insulation material 21 and the outdoor profile 22, so that the load-bearing main body portion 31 and a part of the installation main body portion 321 are suspended above the heat insulation material 21 and the outdoor profile 22. In this way, the structure for realizing the suspension of the load-bearing main body portion 31 and a part of the installation main body portion 321 relative to the heat insulation material 21 and the outdoor profile 22 is simplified, and the production cost of the glass load-bearing member 30 is reduced.

[0082] Furthermore, as Figure 1As shown, a limiting component is provided between the limiting installation part 32 and the indoor profile 23. After the indoor side end of the limiting installation part 32 is inserted into the installation groove 44, the limiting component restricts the movement of the limiting installation part 32 relative to the indoor profile 23, thereby restricting the left - right movement of the glass load - bearing component 30 in its length direction. By the limiting component, the deviation of the glass load - bearing component 30 after being installed on the indoor profile 23 is more reliably restricted, ensuring that the glass load - bearing component 30 does not move relative to the indoor profile 23 during and after the installation of the subsequent door and window glass 10, guaranteeing the initial force distribution and ensuring the reasonable force - bearing of the lower profile 20.

[0083] Further, the preferred structure of the limiting component is as follows: As Figure 1 and Figure 2 shown, there are two groups of left - right limiting components. Each group of limiting components includes a first connection hole 327 opened in the installation main body part 321, a second connection hole 46 opened in the bottom profile main body 42, and a vertically arranged limiting member 50. The limiting member 50 is fixed in the first connection hole 327 and the second connection hole 46. Preferably, the first connection hole 327 is a counterbore, and the limiting member 50 is a countersunk - head limiting part 51 (such as a flat - head screw), to prevent the upper end of the limiting member 50 from being higher than the top surface of the installation main body part 321, so that the limiting member 50 does not interfere with the installation of the subsequent door and window glass 10. Of course, in other embodiments, the limiting member 50 can also be a pin. In addition, in other embodiments, the limiting component can also be multiple limiting blocks protruding upward from the top surface of the bottom profile main body 42, and the limiting blocks are inserted into the installation main body part 321.

[0084] Further, as Figure 1 shown, the door and window glass load - bearing structure further includes a glass cushion block 60. The glass cushion block 60 is arranged on the top surface of the load - bearing main body part 31 and is fixedly connected to the load - bearing main body part 31. By providing the glass cushion block 60, it is avoided that the door and window glass 10 directly contacts the glass load - bearing component 30 of the aluminum profile. In particular, since the glass cushion block 60 is fixedly connected to the load - bearing main body part 31, the glass cushion block 60 does not shift relative to the load - bearing main body part 31 of the glass load - bearing component 30 during and after the installation of the door and window glass 10, and thus does not change the force distribution of the glass load - bearing component 30 after the installation of the door and window glass 10, reliably ensuring the reasonable force - bearing of the lower profile 20. There are various fixing methods for the glass cushion block 60 and the load - bearing main body part 31, such as adhesive fixing, screw fixing, or snap - type fixing. In this embodiment, the glass cushion block 60 is a self - adhesive cushion block, and the glass cushion block 60 is adhesively fixed to the load - bearing main body part 31, which is convenient for the fixed installation of the glass cushion block 60 and reduces costs.

[0085] In summary, the assembly process of the door and window glass load - bearing structure with the above - mentioned structure includes the following steps:

[0086] S1. As Figure 6a andFigure 7a As shown, the glass load-bearing member 30 is tilted forward and upward relative to the horizontal plane and at a relatively large tilt angle, whereby the second limiting protrusion 323 is inserted into the installation groove 44 from the installation opening 45 of the indoor-side profile 23.

[0087] S2. As Figure 6b , Figure 7b and Figure 8 shown, while rotating the glass load-bearing member 30 downward, the rear end of the limiting installation part 32 is snapped into the installation groove 44 through the installation opening 45; during this process, the first limiting protrusion 322 is inserted into the installation groove 44 from the installation opening 45 of the indoor-side profile 23. Along with the continuous rotation of the glass load-bearing member 30, the first limiting plane 324 at the rear end of the first limiting protrusion 322 abuts against the front wall surface of the side profile main body 41, the second limiting plane 325 at the front end of the second limiting protrusion 323 abuts against the inner wall surface of the profile hook part 43, and the third limiting plane 326 at the lower end of the installation main body part 321 abuts against the upper wall surface of the bottom-side profile main body 42, forming multi-point limiting to restrict the continuous rotation of the glass load-bearing member 30; thus far, the glass load-bearing member 30 is snapped in place in the installation groove 44, and the rear end of the limiting installation part 32 is completely embedded in the installation groove 44.

[0088] S3. As Figure 6c and Figure 7c shown, the flat head screws are sequentially screwed into the first connection hole 327 in the installation main body part 321 and the second connection hole 46 in the bottom-side profile main body 42 to complete the installation of the limiting member 50.

[0089] S4. As Figure 6d and Figure 7d shown, the self-adhesive glass cushion block 60 is pasted and fixed on the top surface of the load-bearing main body part 31 in the glass load-bearing member 30 to complete the fixed installation of the glass cushion block 60; thus far, the assembly of the door and window glass load-bearing structure is completed. After that, as Figure 6e and Figure 7e shown, the door and window glass 10 is assembled on the lower-side profile 20.

[0090] The above-mentioned door and window glass load-bearing structure adopts a multi-component combined structure composed of the lower-side profile 20, the glass load-bearing member 30, the limiting member 50, and the self-adhesive glass cushion block 60, which improves the mobility of the glass load-bearing member 30 and the glass cushion block 60 in the prior art, effectively prevents the heat insulation effect of the lower-side profile 20 from being damaged due to the overlap of the glass load-bearing member 30 with the outdoor-side profile 22 and / or the heat insulation material 21 in the lower-side profile 20, and reliably ensures the best heat preservation performance and load-bearing effect of the lower-side profile 20.

[0091] Based on the fact that the first embodiment of the door and window glass load-bearing structure and the second embodiment of the door and window glass load-bearing structure are front-back mirror structures, then in the second embodiment of the door and window glass load-bearing structure, asFigure 11 As shown, the side profile body 41, the bottom profile body 42 and the profile hook 43 are structural features of the outdoor profile 22. The side profile body 41 is distributed on the outdoor side (i.e., the front side) of the limiting installation part 32, and the profile hook 43 is fixed on the indoor side (i.e., the rear side) of the side profile body 41. After the glass load-bearing component 30 is installed on the outdoor profile 22, and during and after the subsequent door and window glass 10 is installed, the three-point limiting structure between the front end of the glass load-bearing component 30 and the outdoor profile 22 effectively restricts the forward and backward movement of the glass load-bearing component 30 in the indoor and outdoor directions, and restricts the downward movement of the glass load-bearing component 30, so that the glass load-bearing component 30 will not move relative to the outdoor profile 22, and reliably ensures the glass load-bearing component 30 and the insulation material 21 and the indoor profile 23. There is a gap 90 and there is no contact overlap, especially effectively avoiding the load-bearing main body 31 of the glass load-bearing component 30 from overlapping with the indoor side profile 23 and / or the insulation material 21 of the lower side profile 20 due to offset, thereby effectively avoiding the connection of the broken bridge profiles constituting the lower side profile 20, ensuring the thermal insulation performance of the lower side profile 20, and thus ensuring the thermal insulation performance of the doors and windows, and then reliably ensuring the best force distribution of the glass load-bearing component 30, so that the force on the lower side profile 20 is reasonable, ensuring the bearing capacity of the lower side profile 20.

[0092] Furthermore, the present application also provides a door and window, in which two embodiments of the above-mentioned door and window glass load-bearing structure are installed.

[0094] Door and window embodiment 2, door and window embodiment 2 is an openable door and window, and the opening method of the openable door and window can be horizontal opening, outward opening or inward opening. Based on this, Figure 9 As shown, the second embodiment of the door and window comprises a fixed outer frame, a door and window leaf movably mounted on the fixed outer frame, and the above-mentioned door and window glass load-bearing structure.
