Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of doors and windows, and particularly provides a door and window glass bearing structure and a door and window comprising the same. BACKGROUND

[0002] At present, a door and window mainly comprises a door and window frame and a door and window glass installed in the door and window frame, and 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 preservation performance and the bearing capacity of the door and window frame are very important. In order to improve the heat preservation 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, so that the left profile, the right profile, the upper profile and the lower profile of the door and window frame all comprise an indoor side profile, an outdoor side profile and a heat insulation material connected between the indoor side profile and the outdoor side profile. At the same time, in order to improve the glass bearing capacity of the door and window frame, a supporting plate component is arranged in the door and window frame and abuts against the door and window glass directly below. For example, a profile and a glass body are disclosed in a Chinese utility model patent with the publication number CN214365651U, and the glass body supporting plate is assembled directly below the door and window glass. However, the prior art has the following defects:

[0003] 1. After the glass body supporting plate is installed in the indoor side profile of the lower profile, there is a gap between the glass body supporting plate and the indoor side profile. Thus, after the door and window glass is installed subsequently, under the double effects of the gravity of the door and window glass borne by the glass body supporting plate and the gap between the glass body supporting plate and the indoor side profile, the free end of the glass body supporting plate away from the indoor side profile is prone to sagging and to be lapped with the outdoor side profile of the lower profile, heat transfer is caused, the adverse phenomenon of a connecting bridge is caused between the indoor side profile and the outdoor side profile of the lower profile, the heat insulation effect of the lower profile is damaged, and finally the overall heat preservation performance of the door and window frame is damaged.

[0004] 2. Since the door and window glass cannot directly contact the glass body supporting plate of the aluminum profile, a glass pad needs to be placed on the top surface of the glass body supporting plate when the door and window glass is installed, and the glass pad is separated between the bottom surface of the door and window glass and the top surface of the glass body supporting plate. However, the glass pad is only placed on the top surface of the glass body supporting plate, and there is no other connection relationship between the two. Thus, before the door and window glass is installed and during the installation process of the door and window glass, the glass pad and the glass body supporting plate are prone to relative movement, so as to change the stress distribution of the glass body supporting plate after the door and window glass is installed, and affect the overall bearing effect of the door and window frame. SUMMARY

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present application is to provide a door and window glass bearing structure that effectively avoids the indoor and outdoor connection of the lower profile caused by the overlapping of the glass bearing component and the non-contact material in the lower profile (i.e., the indoor side profile or the outdoor side profile that does not contact the glass bearing component).

[0006] To achieve the above-mentioned purpose, the present application provides a door and window glass bearing structure, which comprises a lower profile and a glass bearing component, both of which are used to assemble at the lower end of the door and window glass. The lower profile comprises an indoor side profile, a thermal insulation material, and an outdoor side profile connected in sequence along the indoor and outdoor direction. One of the indoor side profile and the outdoor side profile is a bearing fixing material for fixed installation of the glass bearing component, and the other is a non-contact material that does not contact the glass bearing component. The glass bearing component comprises a bearing main body portion for bearing the door and window glass, and a limiting installation portion fixed at one end side of the bearing main body portion facing the bearing fixing material. The limiting installation portion comprises an installation main body portion, a first limiting protrusion portion protruding from the outer periphery of the installation main body portion toward the bearing fixing material, and a second limiting protrusion portion protruding upward from the top of the installation main body portion.

[0007] The bearing fixing material comprises a side profile main body located at the outer periphery side of the limiting installation portion, a bottom side profile main body located at the lower side of the limiting installation portion, and a profile hook portion fixed to the side profile main body and distributed above the bottom side profile main body. An installation groove is formed between the side profile main body, the bottom side profile main body, and the profile hook portion, and an installation opening is located at the end of the installation groove away from the side profile main body.

[0008] When the limiting installation portion is inserted into the installation groove away from the end of the bearing main body portion, the end of the first limiting protrusion portion away from the bearing main body portion is in abutting cooperation with the outer wall surface of the side profile main body, the end of the second limiting protrusion portion toward the bearing main body portion is in abutting cooperation with the inner wall surface of the profile hook portion, and the bottom of the installation main body portion is in abutting cooperation with the outer wall surface of the bottom side profile main body. A gap is formed between the glass bearing component and the thermal insulation material and the non-contact material.

[0009] The lower profile in the present application is a broken bridge profile, and the glass bearing structure of the door and window is a glass support structure for supporting the glass of the door and window with the broken bridge profile. In the glass bearing structure of the door and window involved in the present application, the glass bearing component is installed on the bearing fixed material through the limiting installation part to realize the overall installation of the glass bearing component on the bearing fixed material, and the fixed installation of the glass bearing component in the lower profile is realized. In particular, after the limiting installation part of the glass bearing component is installed in the installation groove of the bearing fixed material, the first limiting protrusion is abutted and matched with the main body of the side profile, the second limiting protrusion is abutted and matched with the profile hook part, and the installation main part is abutted and matched with the main body of the bottom profile, three-point limiting is realized, the movement of the glass bearing component in the indoor and outdoor directions and the downward movement are constrained; and after the door and window glass is installed, the glass bearing component bears the gravity of the door and window glass, through the abutment and matching of the first limiting protrusion with the main body of the side profile, the abutment and matching of the second limiting protrusion with the profile hook part, and the abutment and matching of the installation main part with the main body of the bottom profile, the movement of the glass bearing component in the indoor and outdoor directions and the downward movement are constrained, and the gravity of the door and window glass can be reliably transmitted to the bearing fixed material. Therefore, the glass bearing component will not move relative to the bearing fixed material when the glass bearing component is installed, and after the door and window glass is installed and installed. On the one hand, it reliably ensures that the glass bearing component always hangs above the upper side of the heat insulation material and the non-contact material, effectively avoids the overlapping of the bearing main part of the glass bearing component with the non-contact material and / or the heat insulation material of the lower profile due to the deviation, thereby effectively avoiding the connection of the broken bridge profile constituting the lower profile, ensuring the heat insulation performance of the lower profile, and ensuring the heat preservation performance of the door and window; on the other hand, the optimal stress distribution of the glass bearing component is reliably ensured, and finally the stress of the lower profile is reasonable, ensuring the bearing capacity of the lower profile.

[0010] Further, one end of the first limiting protrusion away from the bearing main part is provided with a first limiting plane, and the first limiting plane is in surface contact with the outer wall surface of the side profile main body; one end of the second limiting protrusion towards the bearing main part is provided with a second limiting plane, and the second limiting plane is in surface contact with the inner wall surface of the profile hook part; the bottom of the installation main part is provided with a third limiting plane, and the third limiting plane is in surface contact with the outer wall surface of the bottom profile main body. In this way, the first limiting protrusion and the side profile main body, the second limiting protrusion and the profile hook part, and the installation main part and the bottom profile main body are all in surface contact, have a larger contact area, more reliably constrain the movement of the glass bearing component, and more reliably transmit the gravity of the door and window glass to the lower profile by the glass bearing component, finally effectively improve the stress rationality of the whole door and window, and prolong the service life of the whole door and window.

[0011] Further, the bottom surface of the glass load-bearing component is provided with an inclined surface, which covers the bottom surface of the load-bearing body part and part of the bottom surface of the mounting body part, the inclined surface is arranged in a manner that it is inclined upwardly away from the load-bearing fixing material, and the inclined surface forms a gap between the glass load-bearing component and the thermal insulation material and the non-contact material. In this way, the suspended structure of the glass load-bearing component relative to the thermal insulation material and the non-contact material is simplified, and the production cost of the glass load-bearing component is reduced.

[0012] Further, the mounting opening allows the first limiting protrusion and the second limiting protrusion to enter the mounting groove from one side of the mounting groove. Based on this, when the limiting mounting part is mounted into the mounting groove away from the one end of the load-bearing body part, the second limiting protrusion is first clamped into the mounting groove through the mounting opening, and then the one end of the glass load-bearing component away from the load-bearing fixing material is rotated downwardly, in this process, the first limiting protrusion is clamped into the mounting groove through the mounting opening until the limiting mounting part is mounted in place in the mounting groove; after the one end of the limiting mounting part away from the load-bearing body part is mounted into the mounting groove, the first limiting protrusion, the second limiting protrusion, and part of the mounting body part are accommodated in the mounting groove, and the mounting body part is arranged in the mounting opening. Therefore, when the glass load-bearing component is mounted, the glass load-bearing component is mounted on the load-bearing fixing material in a rotating manner, and the one end of the limiting mounting part away from the load-bearing body part is clamped into the mounting groove through the mounting opening while the glass load-bearing component is rotated downwardly, so that the load-bearing body part of the glass load-bearing component gradually approaches the non-contact material and the thermal insulation material during the mounting process of the glass load-bearing component, which more effectively avoids the load-bearing body part from overlapping with the non-contact material and / or the thermal insulation material during the mounting of the glass load-bearing component, and avoids the lower profile bridge.

[0013] Further, a limiting assembly is arranged between the limiting mounting part and the load-bearing fixing material; after the one end of the limiting mounting part away from the load-bearing body part is mounted into the mounting groove, the limiting assembly limits the movement of the limiting mounting part relative to the load-bearing fixing material. The preferred structure of the limiting assembly is that the limiting assembly includes a first connecting hole arranged in the mounting body part, a second connecting hole arranged in the bottom profile body, and a limiting piece fixed in the first connecting hole and the second connecting hole. The limiting assembly more reliably limits the deviation of the glass load-bearing component after being mounted on the load-bearing fixing material, ensures that the glass load-bearing component does not move relative to the load-bearing fixing material during and after the subsequent installation of the door and window glass, guarantees the initial stress distribution, and ensures the rationality of the stress of the lower profile.

[0014] Preferably, the first connecting hole is a counterbore, and the limiting piece is a countersunk limiting component, which avoids the upper end of the limiting piece being higher than the top surface of the mounting body part, so that the limiting piece does not interfere with the subsequent installation of the door and window glass.

[0015] Further, the glass bearing component is an integral molding and is an aluminum profile, facilitating production of the glass bearing component and making the glass bearing component have good structural strength.

[0016] Further, the door and window glass bearing structure further comprises a glass pad block, which is arranged on the top surface of the bearing main body and is fixedly connected with the bearing main body. By arranging the glass pad block, the door and window glass is prevented from directly contacting the glass bearing component of the aluminum profile; in particular, the glass pad block is fixedly connected with the bearing main body, and the glass pad block will not be offset relative to the bearing main body of the glass bearing component when the door and window glass is installed and after installation, so that the stress distribution of the glass bearing component after installation of the door and window glass is not changed, and the stress rationality of the lower profile is reliably ensured.

[0017] Preferably, the glass pad block is a self-adhesive pad block, which is fixedly attached with the bearing main body, facilitating fixed installation of the glass pad block and reducing cost.

[0018] The present application provides a door and window, which can be a fixed door and window that cannot be opened or an openable door and window that can be opened and closed. When the door and window is a fixed door and window, the door and window comprises a fixed outer frame, a door and window glass fixed to the fixed outer frame, and a door and window glass bearing structure as described above, which is arranged between the lower end of the door and window glass and the fixed outer frame, so that the lower profile in the door and window glass bearing structure is the profile in the fixed outer frame that is fitted at the lower end of the door and window glass. When the door and window is an openable door and window, the door and window comprises a fixed outer frame, a door leaf movably installed in the fixed outer frame, and a door and window glass bearing structure as described above, the door leaf comprises a leaf frame and a door and window glass fixed to the leaf frame, and the door and window glass bearing structure is arranged between the lower end of the door and window glass in the door leaf and the leaf frame, so that the lower profile in the door and window glass bearing structure is the profile in the leaf frame that is fitted at the lower end of the door and window glass.

[0019] As described above, the door and window glass bearing structure and the door and window according to the present application have the following beneficial effects:

[0020] This application ensures that the glass load-bearing components do not move relative to the load-bearing fixing material during installation of the glass load-bearing components, as well as during and after the installation of the door and window glass. This is achieved through the abutting cooperation between the first limiting protrusion and the side profile body, the abutting cooperation between the second limiting protrusion and the profile hook, and the abutting cooperation between the mounting body and the bottom profile body. On the one hand, it reliably ensures that the glass load-bearing components are always suspended above the thermal insulation material and non-contact material, effectively preventing the load-bearing body of the glass load-bearing components from overlapping with the non-contact material and / or thermal insulation material of the lower profile due to displacement. This effectively prevents the formation of a thermal break profile bridge in the lower profile, ensuring the thermal insulation performance of the lower profile, and thus ensuring the thermal insulation performance of the door and window. On the other hand, it reliably ensures the optimal stress distribution of the glass load-bearing components, ultimately making the stress on the lower profile reasonable and ensuring the load-bearing capacity of the lower profile.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0067] This application provides a door and window glass load-bearing structure, and a door and window equipped with the door and window glass load-bearing structure.

[0068] For ease of description, in the following embodiments, the directions are defined as follows: the width direction of the door / window is defined as the left-right direction, the height direction is defined as the up-down direction, and the thickness direction is defined as the front-back direction. The thickness direction of the door / window is also the indoor / outdoor direction, with the outdoor side being the front direction and the indoor side being the back direction. Based on this, Figure 1 and Figure 11 In the view shown, the left and right sides of the paper are the front and back directions, respectively; the top and bottom sides of the paper are the top and bottom directions, respectively; and the front and back sides of the paper are the left and right directions, respectively.

[0069] like Figure 1 As shown, or as Figure 11 As shown, the window and door glass load-bearing structure of the present invention includes a lower profile 20 and a glass load-bearing component 30, both used for mounting on the lower end of the window and door glass 10. The length direction of the lower profile 20 and the glass load-bearing component 30 is consistent with the width direction of the window and door, both being in the left-right direction. The lower profile 20 is a thermally broken profile, so the window and door glass load-bearing structure is a glass support structure used to support the window and door glass 10 by the thermally broken profile. The thermally broken profile constituting the lower profile 20 includes an interior profile 23 distributed on the rear side, an exterior profile 22 distributed on the front side, and a thermal insulation material 21 fixedly embedded between the interior profile 23 and the exterior profile 22; the thermal insulation material 21 is preferably PK material, and the interior profile 23 and the exterior profile 22 are preferably both integrally formed aluminum profiles.

[0070] Furthermore, of the indoor profile 23 and the outdoor profile 22, one is a load-bearing fixing member 40 for the fixed installation of the glass load-bearing component 30, and the other is a non-contact member 110 that does not contact the glass load-bearing component 30. Thus, the door and window glass load-bearing structure has two embodiments. In the first embodiment of the door and window glass load-bearing structure, as... Figure 1 As shown, the glass load-bearing component 30 is fixed to the indoor profile 23 and does not contact the outdoor profile 22. In this case, the indoor profile 23 constitutes the load-bearing fixing member 40, and the outdoor profile 22 constitutes the non-contact member 110. In the second embodiment of the door and window glass load-bearing structure, as... Figure 11 As shown, the glass load-bearing component 30 is fixed to the outdoor profile 22 and does not contact the indoor profile 23. In this case, 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 door and window glass load-bearing structure and the second embodiment of the door and window glass load-bearing structure are mirror images of each other. The preferred structure of the lower profile 20 and the glass load-bearing component 30 will be described below using the first embodiment of the door and window glass load-bearing structure as an example.

[0071] like Figure 1 , Figure 6e and Figure 7e As shown, the glass load-bearing component 30 includes a load-bearing main body 31 and a limiting installation part 32 fixed on the indoor side (i.e., the rear side) of the load-bearing main body 31; wherein, the window glass 10 is installed above the load-bearing main body 31, and the load-bearing main body 31 supports the window glass 10. The top surface of the load-bearing main body 31 is a horizontal plane. The limiting installation part 32 is installed on the indoor side profile 23, thereby installing the glass load-bearing component 30 as a whole on the indoor side profile 23, or in other words, fixing the glass load-bearing component 30 as a whole in the lower side profile 20.

[0072] In particular, such as Figure 1As shown, the indoor profile 23 (i.e., load-bearing fixing member 40) includes a side profile body 41 located on the indoor side (i.e., rear side) of the limiting installation part 32, a bottom profile body 42 located below the limiting installation part 32, and a profile hook 43 fixed on the outdoor side (i.e., front side) of the side profile body 41; the profile hook 43 is generally inverted L-shaped, having a horizontal section extending forward horizontally from the front wall surface of the side profile body 41, and a vertical section extending downward vertically from the front end of the horizontal section. The straight section is suspended above the bottom profile body 42; thus, a mounting groove 44 and a mounting opening 45 located at the outer end (i.e., front end) of the mounting groove 44 are formed between the side profile body 41, the bottom profile body 42, and the profile hook 43. The mounting groove 44 is formed on the front side of the side profile body 41, the upper side of the bottom profile body 42, and the inner circumference of the profile hook 43. The mounting opening 45 is formed between the vertical section of the profile hook 43 and the bottom profile body 42. Figures 2 to 5 As shown, the limiting installation part 32 includes an installation main body part 321, a first limiting protrusion 322 protruding rearward from the indoor side of the installation main body part 321 toward the interior, and a second limiting protrusion 323 protruding upward from the top of the installation main body part 321.

[0073] When installing the glass load-bearing component 30 onto the interior profile 23, the interior end (i.e., the rear end) of the limiting mounting part 32 is inserted into the mounting groove 44 of the interior profile 23. Once the interior end of the limiting mounting part 32 is inserted into the mounting groove 44 and properly installed, as... Figure 1 As shown, the first limiting protrusion 322, the second limiting protrusion 323, and the rear end portion of the mounting body 321 are all accommodated in the mounting groove 44, and the mounting body 321 simultaneously passes through the mounting opening 45; in particular, the indoor end (i.e., the rear end) of the first limiting protrusion 322 is connected to the front outer wall surface of the side profile body 41, the outdoor end (i.e., the front end) of the second limiting protrusion 323 is connected to the inner wall surface (i.e., the rear wall surface of the vertical section) of the profile hook portion 43, and The bottom of the mounting body 321 abuts against the upper outer wall of the bottom profile body 42, and the glass load-bearing component 30 (i.e., the front part of the load-bearing body 31 and the mounting body 321) located directly above the insulation material 21 and the outdoor profile 22 (i.e., the non-contact material 110) is suspended above the insulation material 21 and the outdoor profile 22, thus forming a gap 90 between the glass load-bearing component 30 and the insulation material 21 and the outdoor profile 22. The outer wall of the side profile body 41 that abuts against the rear end of the first limiting protrusion 322 and the inner wall of the profile hook 43 that abuts against the front end of the second limiting protrusion 323 are both groove walls of the mounting groove 44.

[0074] In the door and window glass load-bearing structure of the present invention, after the glass load-bearing component 30 is installed on the indoor profile 23, three-point limiting is achieved through the abutment cooperation between the rear end of the first limiting protrusion 322 and the side profile body 41, the abutment cooperation between the front end of the second limiting protrusion 323 and the profile hook 43, and the abutment cooperation between the lower end of the mounting body 321 and the bottom profile body 42. Thus, after the glass load-bearing component 30 is installed, and during and after the subsequent installation of the door and window glass 10, the three-point limiting structure between the rear end of the glass load-bearing component 30 and the indoor 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 profile 23. Based on this, on the one hand, it reliably ensures that the load-bearing main body 31 and part of the mounting main body 321 of the glass load-bearing component 30 are always suspended above the thermal insulation material 21 and the outdoor profile 22. There is a gap 90 between the glass load-bearing component 30 and the thermal insulation material 21 and the outdoor profile 22, and they do not contact or overlap. In particular, it effectively prevents the load-bearing main body 31 of the glass load-bearing component 30 from overlapping with the outdoor profile 22 and / or the thermal insulation material 21 of the lower profile 20 due to displacement, thereby effectively preventing the formation of a thermal break profile bridge in the lower profile 20, ensuring the thermal insulation performance of the lower profile 20, and thus ensuring the thermal insulation performance of the doors and windows. On the other hand, it reliably enables the glass load-bearing component 30 to transfer the weight of the door and window glass 10 to the indoor profile 23, avoiding changes in its stress distribution due to the displacement of the glass load-bearing component 30, thereby ensuring the optimal stress distribution of the glass load-bearing component 30, making the stress on the lower profile 20 reasonable, and ensuring the load-bearing capacity of the lower profile 20.

[0075] Clearly, the load-bearing structure of the window and door glass involved in this application effectively ensures the optimal thermal insulation performance of the lower profile 20 and effectively reduces heat loss from the lower profile 20, which is conducive to the implementation of energy-saving and environmental protection policies. At the same time, it reliably ensures the overall energy-saving effect of the window and door, allowing for an increase in the overall size and area of ​​the window and door while maintaining a certain energy consumption, thereby expanding the indoor view and lighting, and enhancing the product competitiveness of the window and door. Furthermore, the load-bearing structure of the window and door glass involved in this application also effectively ensures the optimal load-bearing effect of the lower profile 20, improves the overall stress rationality of the window and door, and extends the overall service life of the window and door.

[0076] Furthermore, such as Figures 2 to 5As shown, the rear end of the first limiting protrusion 322 is provided with a first limiting plane 324, which contacts the front outer wall surface of the side profile body 41. The front end of the second limiting protrusion 323 is provided with a second limiting plane 325, which contacts the inner wall surface of the profile hook 43. The bottom of the mounting body 321 is provided with a third limiting plane 326, which contacts the upper outer wall surface of the bottom profile body 42. Thus, the first limiting protrusion 322 and the side profile body 41, the second limiting protrusion 323 and the profile hook 43, and the mounting body 321 and the bottom profile body 42 are all in surface contact, with a large contact area, which more reliably restrains the front-back movement and downward movement of the glass load-bearing component 30, avoids bridging, and at the same time enables the glass load-bearing component 30 to more reliably transfer the weight of the door and window glass 10 to the indoor profile 23, ultimately effectively improving the overall thermal insulation performance and stress rationality of the door and window, and extending the overall service life of the door and window.

[0077] Preferably, such as Figures 2 to 5 As shown, the length direction of the first limiting protrusion 322 and the second limiting protrusion 323 is consistent with the length direction of the glass load-bearing component 30, and their lengths are equal. Simultaneously, the length directions of the first limiting plane 324, the second limiting plane 325, and the third limiting plane 326 are also consistent with the length direction of the glass load-bearing component 30, and their lengths are also equal. Thus, 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 form a continuous extending structure along the length direction of the glass load-bearing component 30. This improves the reliability of the surface contact between the first limiting protrusion 322 and the side profile body 41, the second limiting protrusion 323 and the profile hook 43, and the mounting body 321 and the bottom profile body 42, thereby improving the limiting and stopping effect of the glass load-bearing component 30 after it is installed in place.

[0078] Preferably, such as Figures 2 to 5 As shown, the first limiting plane 324, the second limiting plane 325, and the third limiting plane 326 are triangularly distributed. After the glass load-bearing component 30 is installed in place, the contact points between the first limiting protrusion 322 and the side profile body 41, the contact points between the second limiting protrusion 323 and the profile hook 43, and the contact points between the mounting body 321 and the bottom profile body 42 are also triangularly distributed, ensuring the limiting effect on the glass load-bearing component 30.

[0079] Preferably, the glass load-bearing component 30 is a one-piece molded part made of aluminum profile, which facilitates the production of the glass load-bearing component 30 and also gives the glass load-bearing component 30 good structural strength. Of course, in other embodiments, the glass load-bearing component 30 can also be made of stainless steel profile.

[0080] Furthermore, the mounting opening 45 of the indoor profile 23 allows the first limiting protrusion 322 and the second limiting protrusion 323 of the glass load-bearing component 30 to enter the mounting groove 44 from the outdoor side of the mounting groove 44. Based on this, when the indoor end of the limiting mounting part 32 is inserted into the mounting groove 44, as... Figure 6a and Figure 6b , Figure 7a and Figure 7b ,as well as Figure 8 As shown, the second limiting protrusion 323 and the first limiting protrusion 322 are successively inserted into the mounting groove 44 through the mounting opening 45, thereby realizing the rotational installation of the glass load-bearing component 30 into the mounting groove 44 of the indoor profile 23 on the front side of the indoor profile 23. Specifically, as Figure 6a and Figure 7a As shown, first, position the glass load-bearing component 30 at a large tilt angle, and then insert the second limiting protrusion 323 into the mounting groove 44 through the mounting opening 45; then rotate the front end of the glass load-bearing component 30 downwards. During this process, as... Figure 6b , Figure 7b and Figure 8 As shown, the second limiting protrusion 323 gradually approaches the rear wall surface of the vertical section of the profile hook 43, and the first limiting protrusion 322 is inserted into the mounting groove 44 through the mounting opening 45 and gradually approaches the front wall surface of the side profile 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 43. Then the rear end of the limiting mounting part 32 is completely embedded in the mounting groove 44, and the limiting mounting part 32 is installed in the mounting groove 44. At this time, 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 body 41, and the third limiting plane 326 at the lower end of the mounting body part 321 abuts against the upper wall surface of the bottom profile body 42. Since the glass load-bearing component 30 is installed on the indoor profile 23 by rotation, while rotating the glass load-bearing component 30 downwards, the indoor end of the limiting installation part 32 is inserted into the installation groove 44 through the installation opening 45. During the installation of the glass load-bearing component 30, the load-bearing main body 31 of the glass load-bearing component 30 gradually moves downwards towards the outdoor profile 22 and the heat insulation material 21, which more effectively avoids the load-bearing main body 31 from overlapping with the outdoor profile 22 and / or the heat insulation material 21 during the installation of the glass load-bearing component 30, and avoids bridging of the lower profile 20.

[0081] Furthermore, such as Figure 2 , Figure 4 and Figure 5As shown, the bottom surface of the glass load-bearing component 30 is provided with an inclined surface 33. The inclined surface 33 covers the entire bottom surface of the load-bearing main body 31 and part of the front bottom surface of the mounting main body 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 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 mounting main body 321. The inclined surface 33 is inclined upward as it gets further away from the indoor profile 23, or in other words, the inclined surface 33 is inclined forward and upward. The inclined surface 33 creates a gap 90 between the glass load-bearing component 30 and the thermal insulation material 21 and the outdoor profile 22, thereby suspending the load-bearing main body 31 and part of the mounting main body 321 above the thermal insulation material 21 and the outdoor profile 22. In this way, the structure of suspending the load-bearing main body 31 and part of the mounting main body 321 relative to the thermal insulation material 21 and the outdoor profile 22 is simplified, and the production cost of the glass load-bearing component 30 is reduced.

[0082] Furthermore, such as Figure 1 As shown, a limiting component is provided between the limiting mounting part 32 and the interior profile 23. When the interior end of the limiting mounting part 32 is inserted into the mounting groove 44, the limiting component restricts the movement of the limiting mounting part 32 relative to the interior profile 23, thereby restricting the lateral movement of the glass load-bearing component 30 in its length direction. By using the limiting component to more reliably restrict the offset of the glass load-bearing component 30 after it is installed on the interior profile 23, it is ensured that the glass load-bearing component 30 will not move relative to the interior profile 23 during and after the subsequent installation of the door and window glass 10, thus ensuring the initial force distribution and the rationality of the force on the lower profile 20.

[0083] Furthermore, the preferred structure of the limiting component is as follows: Figure 1 and Figure 2 As shown, the limiting components are divided into left and right groups. Each group of limiting components includes a first connecting hole 327 in the mounting body 321, a second connecting hole 46 in the bottom profile body 42, and a vertically arranged limiting member 50. The limiting member 50 is fixed in the first connecting hole 327 and the second connecting hole 46. Preferably, the first connecting hole 327 is a countersunk hole, and the limiting member 50 is a countersunk limiting component 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 mounting body 321, so that the limiting member 50 will not interfere with the subsequent installation of the 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 components can also be multiple limiting blocks protruding upward from the top surface of the bottom profile body 42, and the limiting blocks are inserted into the mounting body 321.

[0084] Furthermore, such as Figure 1As shown, the load-bearing structure of the window and door glass also includes a glass pad 60, which is disposed on the top surface of the load-bearing main body 31 and fixedly connected to it. By providing the glass pad 60, direct contact between the window and door glass 10 and the glass load-bearing component 30 of the aluminum profile is avoided. In particular, the fixed connection between the glass pad 60 and the load-bearing main body 31 ensures that the glass pad 60 will not shift relative to the load-bearing main body 31 during and after the installation of the window and door glass 10, thus maintaining the stress distribution of the glass load-bearing component 30 after installation and reliably ensuring the reasonable stress distribution of the lower profile 20. There are various methods for fixing the glass pad 60 to the load-bearing main body 31, such as adhesive fixing, screw fixing, or snap-on fixing. In this embodiment, the glass pad 60 is a self-adhesive pad, which is adhesively fixed to the load-bearing main body 31, facilitating the installation of the glass pad 60 and reducing costs.

[0085] In summary, the assembly process of a load-bearing glass structure for doors and windows with the above-mentioned structure includes the following steps:

[0086] S1, such as Figure 6a and Figure 7a As shown, the glass load-bearing component 30 is tilted forward and upward relative to the horizontal surface at a large tilt angle, thereby inserting the second limiting protrusion 323 into the mounting groove 44 from the mounting opening 45 of the indoor profile 23.

[0087] S2, such as Figure 6b , Figure 7b and Figure 8 As shown, while rotating the glass load-bearing component 30 downwards, the rear end of the limiting mounting part 32 is engaged in the mounting groove 44 through the mounting opening 45. During this process, the first limiting protrusion 322 is inserted into the mounting groove 44 from the mounting opening 45 of the indoor profile 23. As the glass load-bearing component 30 continues to rotate, 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 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 mounting body part 321 abuts against the upper wall surface of the bottom profile body 42, forming multi-point limiting to restrict the continued rotation of the glass load-bearing component 30. At this point, the glass load-bearing component 30 is engaged in the mounting groove 44, and the rear end of the limiting mounting part 32 is completely embedded in the mounting groove 44.

[0088] S3, such as Figure 6c and Figure 7c As shown, the flat-head screws are screwed into the first connecting hole 327 in the mounting body 321 and the second connecting hole 46 in the bottom profile body 42 in sequence to complete the installation of the limiting member 50.

[0089] S4, such asFigure 6d and Figure 7d As shown, the self-adhesive glass pad 60 is attached and fixed to the top surface of the load-bearing main body 31 in the glass load-bearing component 30, completing the fixed installation of the glass pad 60; thus, the assembly of the door and window glass load-bearing structure is completed. Afterwards, as... Figure 6e and Figure 7e As shown, the window glass 10 is assembled onto the lower profile 20.

[0090] The aforementioned door and window glass load-bearing structure adopts a multi-component combination structure consisting of a lower profile 20, a glass load-bearing component 30, a limiting component 50, and a self-adhesive glass pad 60. This improves the mobility of the glass load-bearing component 30 and the glass pad 60 in the prior art, effectively preventing damage to the heat insulation effect of the lower profile 20 due to the overlap between the glass load-bearing component 30 and the outdoor profile 22 and / or the thermal insulation material 21 in the lower profile 20, and reliably ensuring the optimal thermal insulation performance and load-bearing effect of the lower profile 20.

[0091] Since Embodiment 1 and Embodiment 2 of the door and window glass load-bearing structure are mirror images of each other, in Embodiment 2 of the door and window glass load-bearing structure, if... Figure 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 located 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 installation of the door and window glass 10, 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, as well as 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, reliably ensuring the connection between the glass load-bearing component 30 and the thermal insulation material 21 and the indoor profile 23. There are gaps 90° and no contact or overlap, which effectively prevents the load-bearing main body 31 of the glass load-bearing component 30 from overlapping with the indoor side profile 23 and / or thermal insulation material 21 of the lower profile 20 due to displacement. This effectively avoids the formation of a thermal break profile bridge in the lower profile 20, ensuring the thermal insulation performance of the lower profile 20, which in turn ensures the thermal insulation performance of the doors and windows. Furthermore, it reliably ensures the optimal stress distribution of the glass load-bearing component 30, making the stress on the lower profile 20 reasonable and ensuring the load-bearing capacity of the lower profile 20.

[0092] Furthermore, this application also provides two embodiments of a door or window equipped with the aforementioned load-bearing structure for the door or window glass. The door or window can be a fixed, non-openable type or an openable, closable type. Two preferred embodiments of the door or window are provided below.

[0093] Example 1 of the door and window embodiment is a fixed door and window that cannot be opened. Based on this, as follows: Figure 9 or Figure 10 As shown, the first embodiment of the door and window includes a fixed outer frame, door and window glass 10 fixed to the fixed outer frame, and the aforementioned load-bearing structure for the door and window glass. The fixed outer frame is fixed to the building and mainly includes an upper outer frame profile 71 mounted on the upper side of the door and window glass 10, a lower outer frame profile 72 mounted on the lower side of the door and window glass 10, a left outer frame profile mounted on the left side of the door and window glass 10, and a right outer frame profile mounted on the right side of the door and window glass 10. The upper outer frame profile 71, the lower outer frame profile 72, the left outer frame profile, and the right outer frame profile are all thermally broken profiles. In the first embodiment of the door and window, the load-bearing structure for the door and window glass is configured between the lower end of the door and window glass 10 and the lower outer frame profile 72 of the fixed outer frame. The lower profile 20 in the load-bearing structure for the door and window glass is also the lower outer frame profile 72 mounted on the lower end of the door and window glass 10 within the fixed outer frame. In addition, when the first embodiment of the door and window has multiple door and window glass panels 10, such as... Figure 10 As shown, in the two adjacent window glass panels 10, the lower outer frame profile 72 installed on the lower side of the upper window glass 10 and the upper outer frame profile 71 installed on the upper side of the lower window glass 10 are a common profile.

[0094] Example 2 of the door and window embodiment describes an operable, closable door and window. The opening mechanism of this type of door and window can be casement, outward, or inward. Based on this, as follows... Figure 9 As shown, the second embodiment of the door and window includes a fixed outer frame, a door and window sash movably installed on the fixed outer frame, and the aforementioned door and window glass load-bearing structure. The fixed outer frame is fixed to the building; the door and window sash includes a sash frame and door and window glass 10 fixed to the sash frame. The sash frame mainly includes an upper sash frame profile 81 mounted on the upper side of the door and window glass 10, a lower sash frame profile 82 mounted on the lower side of the door and window glass 10, a left sash frame profile mounted on the left side of the door and window glass 10, and a right sash frame profile mounted on the right side of the door and window glass 10. The upper sash frame profile 81, the lower sash frame profile 82, the left sash frame profile, and the right sash frame profile are all thermally broken profiles. In the second embodiment of the door and window, the door and window glass load-bearing structure is located between the lower end of the door and window glass 10 and the lower sash frame profile 82 of the sash frame. Therefore, the lower profile 20 in the door and window glass load-bearing structure is also the lower sash frame profile 82 mounted on the lower end of the door and window glass 10 in the sash frame.

[0095] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0096] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
