Description

[Technical Field]

[0001] The present invention relates to a heat insulating structure and fittings at the joints of fittings. [Background technology]

[0002] Building fixtures such as sliding windows and doors typically include a fixed outer frame and at least two shoji screens movably attached to the frame. Each shoji screen includes a frame and a shoji panel attached within the frame, which is usually glass. The opening and closing of the building fixture is achieved by the movement of the shoji screen. Each shoji screen also has a joint, and when the building fixture is closed, the joints of two adjacent shoji screens intersect, forming the joint of the building fixture. In recent years, due to the influence of policies related to reducing CO2 emissions, there has been a demand for highly insulated building materials. In building materials, the joints are the areas with the greatest heat loss, meaning that the heat retention effect (or insulating capacity) of the joints is the weakest point of the building materials.

[0003] In the prior art, the insulation type at the joint of building materials, such as the insulating cover of building materials disclosed in the Chinese utility model with registered utility model number CN208734246U, uses the screen frame of the screen at the joint as an insulating bridge frame, and the insulating bridge frame includes an aluminum alloy profile body and a PA66 insulating material fixed and fitted inside the aluminum alloy profile body. These conventional insulation types have the following defects:

[0004] 1. The insulation technology is simple, and only achieves insulation through the insulation material contained within the insulated bridge profile. This has a low ability to prevent heat from being transmitted from the inside to the outside, which weakens the insulation ability of the joints and ultimately makes it difficult to improve the insulation effect of the entire building material.

[0005] 2. Because the insulation technology is realized only by the insulating bridge section, the gap between the indoor shoji section and the outdoor shoji section at the joint of the door and window is very small, and the two are very close to each other in the indoor and outdoor directions, which causes rapid heat loss. In addition, the insulation capacity is weak, so the temperature of the indoor shoji section at the joint is easily lowered, which makes it easy for condensation to form. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in view of the above, and aims to provide a heat insulating structure and fittings at the joints of fittings that improve the heat insulating capacity at the joints. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a heat insulating structure at the joint of a fitting including an inside joint portion provided on an indoor shoji screen and an outside joint portion provided on an outdoor shoji screen, wherein the inside joint portion includes an indoor-side joint portion shoji shape member of the indoor-side shoji screen and an inside insulating cover attached to the outdoor-side end face of the indoor-side joint portion shoji shape member, and a first hook portion is provided on the inside insulating cover, and the outside joint portion includes an outdoor-side joint portion shoji shape member of the outdoor shoji screen and an outside insulating cover attached to the indoor-side end face of the outdoor-side joint portion shoji shape member, and a second hook portion is provided on the outdoor-side joint portion shoji shape member or the outside insulating cover, Of the indoor-side joint shoji section profile and the outdoor-side joint shoji section profile, at least the indoor-side joint shoji section profile is an insulating bridge section profile, and when the indoor-side shoji and outdoor-side shoji sections are open, the first hook section and the second hook section are separated, and when the indoor-side shoji and outdoor-side shoji sections are closed, the first hook section is located on the outdoor side of the second hook section, and at least a portion of the two sections face each other in the indoor-outdoor direction, and the indoor-side joint shoji section profile, the indoor insulating cover, the outdoor insulating cover and the outdoor joint shoji section profile are positioned facing each other in order in the direction from the inside to the outside of the room, providing an insulating structure at the joint of the building materials.

[0008] In the thermal insulation structure at the joint of the fittings according to the present application, when the fittings are closed, the joint of the fittings is insulated in the indoor / outdoor direction by the indoor-side insulating bridge member (i.e., the indoor-side joint shoji member), the inner insulating cover, the outer insulating cover, and the outdoor joint shoji member, preventing heat from being transmitted from the indoors to the outdoors. The thermal insulation structure of the present application is a multi-layer thermal insulation structure in the indoor / outdoor direction, and the thermal insulation measures are at least the insulating bridge member and the inner and outer double insulating covers, and this multi-layer thermal insulation structure has the following advantages: 1. It effectively reduces heat loss at the joints and greatly improves the insulation capacity of the joints, which is beneficial to the promotion of energy-saving and environmental protection policies, meets the increasing demand for strict energy conservation in the construction industry, and enhances the product competitiveness of building materials. 2. The inner and outer insulating covers are located between the indoor joint shoji profile and the outdoor joint shoji profile, which increases the insulating capacity and increases the distance between the indoor joint shoji profile and the outdoor joint shoji profile in the indoor / outdoor direction, slowing down heat loss and making the indoor joint shoji profile less susceptible to condensation, improving the product performance of the building materials. 3. By improving the insulation capacity of the joints, the insulation coefficient of the entire building material can be effectively reduced, and the application area of ​​the building material can be expanded in the northern region. 4. Improving the insulation capacity of the joints effectively increases the energy-saving effect of the entire building, and allows the overall size and area of ​​the building to be expanded with a given amount of energy consumption, thereby increasing the view and lighting in the room. 5. The inner and outer insulating covers are located between the indoor and outdoor joint shoji shapes and are not exposed on the exterior of the fixture, ensuring the appearance of the fixture.

[0009] Furthermore, the structure of the indoor-side joint shoji frame and the inner heat-insulating cover is preferably such that the indoor-side joint shoji frame includes a frame main member and a frame auxiliary member, the frame main member has a first connection portion located on the indoor side of the frame auxiliary member and a second connection portion located on the outside of the frame auxiliary member along the width direction of the indoor-side shoji, the first connection portion and the second connection portion are fixedly connected to the frame auxiliary member, and the inner heat-insulating cover has an inner cover vertical portion extending linearly along the indoor-outdoor direction and a frame auxiliary member along the width direction of the indoor-side shoji The first inner cover horizontal portion extends from the inner cover vertical portion in a direction away from the second connection portion along the indoor shoji screen width direction, and the second inner cover horizontal portion extends from the inner cover vertical portion toward the second connection portion along the indoor shoji screen width direction, and the inner cover vertical portion and the shaped member auxiliary member, and the second inner cover horizontal portion and the second connection portion are all fitted and fixed together, and the first hook portion extends from the outdoor end of the inner cover vertical portion in a direction away from the second inner cover horizontal portion, and the first hook portion is located on the outdoor side of the first inner cover horizontal portion. The first inner cover horizontal portion and the second inner cover horizontal portion can effectively cover the indoor shoji screen joint portion in the indoor shoji screen width direction, reliably ensuring thermal insulation.

[0010] Furthermore, the fitting structure between the indoor side joint shoji profile and the inner insulation cover preferably has a first fitting protrusion at the indoor side end of the inner cover vertical section, a first fitting groove that accommodates the first fitting protrusion at the profile auxiliary section, a second fitting protrusion and a second fitting groove at the end of the second inner cover horizontal section away from the inner cover vertical section, the second connection section has a third fitting groove that accommodates the second fitting protrusion and a third fitting protrusion that is accommodated in the second fitting groove, and there are first movement gaps between the first fitting protrusion and the groove wall of the first fitting groove, between the second fitting protrusion and the groove wall of the third fitting groove, and between the third fitting protrusion and the groove wall of the second fitting groove, and the first movement gaps allow the inner insulation cover to be movably fitted into the profile main section and the profile auxiliary section. The movable fitting structure of the inner insulating cover allows the inner insulating cover to better undergo thermal expansion and contraction at different heating temperatures during the insulating process, and further enhances the insulating capacity at the joints of the building materials.

[0011] Furthermore, the second inner cover horizontal portion has a two-layer structure, an inner layer and an outer layer, in the indoor / outdoor direction, forming an internal cover space within the second inner cover horizontal portion, thereby further enhancing the insulating capacity at the joints of the building materials.

[0012] Furthermore, the structure of the outdoor joint shoji frame and the outdoor insulation cover preferably has a third connection portion provided on the indoor side of the outdoor joint shoji frame, close to the outer edge of the outdoor shoji frame along the width direction of the outdoor shoji frame, and the outdoor insulation cover includes an outdoor cover vertical portion extending linearly along the indoor-outdoor direction, a first outdoor cover horizontal portion extending from the outdoor cover vertical portion in a direction away from the third connection portion along the width direction of the outdoor shoji frame, and a second outdoor cover horizontal portion extending from the outdoor cover vertical portion toward the third connection portion along the width direction of the outdoor shoji frame, and the outdoor cover vertical portion and outdoor joint shoji frame, as well as the second outdoor cover horizontal portion and the third connection portion are all fitted and fixed, and the second hook portion extends from the indoor end of the third connection portion in a direction approaching the first outdoor cover horizontal portion, and the second hook portion is located on the indoor side of the second outdoor cover horizontal portion. The first outer cover horizontal portion and the second outer cover horizontal portion can effectively cover the outdoor joint shoji profile in the width direction of the outdoor shoji screen, thereby reliably ensuring the heat insulating effect.

[0013] Furthermore, the fitting structure between the exterior joint shoji frame and the exterior insulation cover preferably has a fourth fitting protrusion at the exterior end of the outer cover vertical section, a fourth fitting groove in the exterior joint shoji frame that receives the fourth fitting protrusion, a fifth fitting protrusion at the end of the second outer cover horizontal section away from the exterior cover vertical section, and a fifth fitting groove in the third connection section that receives the fifth fitting protrusion, with second movement gaps between the fourth fitting protrusion and the groove wall of the fourth fitting groove and between the fifth fitting protrusion and the groove wall of the fifth fitting groove, allowing the exterior insulation cover to be movably fitted into the exterior joint shoji frame. The movable fitting structure of the exterior insulation cover allows the exterior insulation cover to better thermally expand and contract at different heating temperatures during the insulation process, further improving the insulation capacity of the joint area of ​​the building materials.

[0014] Furthermore, the heat-insulating structure at the joint of the fittings further includes a first sealant fixed to the outside of the inner joint and a second sealant fixed to the inside of the outer joint, the first sealant being provided in close proximity to the outer edge of the inner shoji screen along the width direction of the inner shoji screen, and the second sealant being provided in close proximity to the outer edge of the outer shoji screen along the width direction of the outer shoji screen, so that when the inner and outer shoji screens are closed, the first sealant abuts against the outer joint and the second sealant abuts against the inner joint. By providing two additional sealants between the inner and outer joints, the flow of cold and warm air between the indoors and outdoors is effectively prevented.

[0015] Furthermore, the inner and outer insulating covers are both made of resin profiles, and the material of the resin profiles is rigid PVC. The inner and outer insulating covers made of resin profiles can effectively suppress heat conduction and further improve the insulating ability at the joints of the building fixtures.

[0016] Furthermore, a preferred structure for the indoor-side joint shoji section includes a main section, a secondary section, and first and second insulating materials that are perpendicular to each other. The main section has a first connecting portion located on the indoor side of the secondary section and a second connecting portion located on the outside of the secondary section along the width of the indoor-side shoji. The first insulating material is fixed between the first connecting portion and the secondary section along the thickness of the indoor-side shoji, and the second insulating material is fixed between the second connecting portion and the secondary section along the width of the indoor-side shoji. The inner insulating cover is attached to the second connecting portion and the secondary section. The insulating bridge section that makes up the indoor-side joint shoji section uses a 90° thermal break structure for the insulating material, improving the insulating effect and further enhancing the insulating capacity of the joint.

[0017] Furthermore, an insulating bridge cavity is formed between the main section and auxiliary section of the insulating bridge section, and the insulating bridge section has insulating foam material provided within the insulating bridge cavity, which further enhances the insulating capacity at the joints of the building components.

[0018] Furthermore, the indoor-side joint shoji screen section is an insulating bridge aluminum section, while the outdoor-side joint shoji screen section is a regular aluminum section. The indoor-side insulating bridge aluminum section, inner insulating cover, and outer insulating cover already provide excellent insulation at the joint. That is, the heat transfer coefficient obtained by the multi-layer insulation structure formed by the indoor-side insulating bridge aluminum section, inner insulating cover, outer insulating cover, and outdoor-side regular aluminum section is very close to the heat transfer coefficient obtained by the multi-layer insulation structure formed by the indoor-side insulating bridge aluminum section, inner insulating cover, outer insulating cover, and outdoor-side insulating bridge aluminum section. Thus, by simply using the indoor-side joint shoji screen section as an insulating bridge aluminum section, the present application can ensure insulation effectiveness and reduce costs.

[0019] The present invention further provides a fitting comprising a fixed outer frame and a plurality of shoji screens movably attached to the outer frame, with two adjacent shoji screens being an indoor shoji screen located on the indoor side and an outdoor shoji screen located on the outdoor side, and wherein a heat insulating structure is provided between the adjacent indoor shoji screen and outdoor shoji screen at the joint of the fittings.

[0020] Furthermore, the outer frame has first and second vertical frames located on both sides of the plurality of shoji screens along the width direction of the door, and each of the first and second vertical frames includes an indoor frame body, an outdoor frame body, and two third insulating materials arranged side by side and fixed between the indoor frame body and the outdoor frame body along the width direction of the door, and the indoor shoji screen further includes, along its width direction, an indoor shoji screen shape member provided opposite the indoor shoji screen shape member at the indoor joint, and a first shoji screen material attached between the indoor shoji screen shape member and the indoor shoji screen shape member, and the indoor shoji screen shape member is an insulating bridge shape member and has two fourth insulating materials arranged side by side along the width direction of the indoor shoji screen, and the outdoor shoji screen further includes, along its width direction, an outdoor shoji screen shape member provided opposite the indoor shoji screen shape member at the indoor joint, and a first shoji screen material attached between the indoor shoji screen shape member and the indoor shoji screen shape member, and the indoor shoji screen shape member is an insulating bridge shape member and has two fourth insulating materials arranged side by side along the width direction of the indoor shoji screen, and the outdoor shoji screen further includes, along its width direction, an outdoor shoji screen shape member. The system further includes an exterior shoji frame member arranged opposite the side joint shoji frame member, and a second shoji panel member attached between the exterior joint shoji frame member and the exterior shoji frame member, the exterior shoji frame member being an insulating bridge frame member and having two fifth insulating materials arranged side by side along the width direction of the exterior shoji frame, and insulating foam material being provided on the periphery of the first shoji frame member, the periphery of the second shoji frame member, between the two third insulating materials, between the two fourth insulating materials, and between the two fifth insulating materials, and when the interior shoji frame and the exterior shoji frame are closed, the outer peripheral region of the third insulating material in the first vertical frame is connected to the outer peripheral region of the fourth insulating material, and the outer peripheral region of the third insulating material in the second vertical frame is connected to the outer peripheral region of the fifth insulating material.

[0021] The building materials with the above structure can realize a continuous insulation line, greatly reduce heat loss, and reliably guarantee the insulation coefficient of the entire window.

[0022] As described above, the insulating structure and fittings at the joints of the fittings according to the present application have the beneficial effect of preventing heat from being transmitted from inside to outside the room when the fittings are closed, as the joints of the fittings are insulated in the indoor / outdoor direction by the insulating bridge member on the indoor side, the inner insulating cover, the outer insulating cover, and the outdoor joint shoji member.

[0023] The insulation structure of the present application is a multi-layer insulation structure in the indoor / outdoor direction, and the insulation measures include at least an insulating bridge profile and an inner and outer double insulating cover, and the multi-layer insulation structure has the following advantages: 1. It effectively reduces heat loss at the joints and greatly improves the insulation capacity of the joints, which is beneficial to the promotion of energy-saving and environmental protection policies, meets the increasing demand for strict energy conservation in the construction industry, and enhances the product competitiveness of building materials. 2. The inner and outer insulating covers are located between the indoor joint shoji profile and the outdoor joint shoji profile, which increases the insulating capacity and increases the distance between the indoor joint shoji profile and the outdoor joint shoji profile in the indoor / outdoor direction, slowing down heat loss and making the indoor joint shoji profile less susceptible to condensation, improving the product performance of the building materials. 3. By improving the insulation capacity of the joints, the insulation coefficient of the entire building material can be effectively reduced, and the application area of ​​the building material can be expanded in the northern region. 4. Improving the insulation capacity of the joints effectively increases the energy-saving effect of the entire building, and allows the overall size and area of ​​the building to be expanded with a given amount of energy consumption, thereby increasing the view and lighting in the room. 5. The inner and outer insulating covers are located between the indoor and outdoor joint shoji shapes and are not exposed on the exterior of the fixture, ensuring the appearance of the fixture.

[0029] The present application provides a thermal insulation structure at the joint of a fitting such as a sliding window or door, and a fitting including the thermal insulation structure at the joint of the fitting. For ease of explanation, in the following examples, the thickness direction of the fitting is defined as the front-to-back direction, the height direction of the fitting is defined as the up-down direction, and the width direction of the fitting is defined as the left-to-right direction. The thickness direction of the fitting also corresponds to the indoor / outdoor direction, with the outdoor direction being the front direction and the indoor direction being the rear direction. Based on this, in the drawing shown in FIG. 1, the front and back of the page are the front and rear directions, respectively, the left and right sides of the page are the right and left directions, respectively, and the top and bottom of the page are the up and down directions, respectively.

[0030] As shown in Figures 1 to 3, the fittings of the present application include a fixed outer frame 90 and multiple shoji screens attached to the outer frame 90 so as to be movable from side to side. The outer frame 90 is fixed to the window / door opening of a building, realizing fixed installation of the entire fittings in the building. The outer frame 90 includes a pair of vertical members arranged side by side and extending vertically, and a pair of horizontal members arranged side by side and extending horizontally. The number of shoji screens is two or more, for example, two, three, four, etc. Two adjacent shoji screens are an indoor shoji screen 10 located on the inside of the room and an outdoor shoji screen 20 located on the outside of the room. For ease of explanation, the following description will be given using an example in which two shoji screens are arranged in the fittings.

[0031] 1 to 3, the indoor shoji screen 10 includes an indoor shoji frame and a first shoji panel 120 attached to the indoor shoji frame, and the outdoor shoji screen 20 includes an outdoor shoji frame and a second shoji panel 140 attached to the outdoor shoji frame, and both the first shoji panel 120 and the second shoji panel 140 are preferably glass. The indoor shoji frame of the indoor shoji screen 10 and the outdoor shoji frame of the outdoor shoji screen 20 each include a pair of vertical members arranged side by side and extending vertically, and a pair of horizontal members arranged side by side and extending horizontally. If the right-side vertical member in the indoor shoji frame is defined as the indoor shoji profile 110, and the left-side vertical member in the indoor shoji frame is defined as the indoor joint shoji profile 30, the indoor joint shoji profile 30 and the indoor shoji profile 110 are arranged opposite each other on the left and right in the width direction of the indoor shoji 10, and the first shoji panel 120 is attached between the indoor joint shoji profile 30 and the indoor shoji profile 110. If the left-side vertical member in the outdoor shoji frame is defined as the outdoor shoji shape member 130, and the right-side vertical member in the outdoor shoji frame is defined as the outdoor joint shoji shape member 50, the outdoor shoji shape member 130 and the outdoor joint shoji shape member 50 are arranged opposite each other on the left and right in the width direction of the outdoor shoji 20, and the second shoji panel material 140 is attached between the outdoor joint shoji shape member 50 and the outdoor shoji shape member 130.

[0032] Furthermore, as shown in Figures 1 and 3, handle locks 150 are attached to the interior sides of both the indoor shoji frame 110 and the outdoor shoji frame 130. When the fitting is opened, the handle lock 150 is unlocked, allowing the indoor shoji frame 10 to move to the left and the outdoor shoji frame 20 to move to the right. When the fitting is closed, the handle lock 150 is locked, and the indoor shoji frame 10 is located at its rightmost position, sealingly joining with the right-side vertical member of the outer frame 90, while the outdoor shoji frame 20 is located at its leftmost position, sealingly joining with the left-side vertical member of the outer frame 90. At the same time, the left end of the indoor shoji frame 10 and the right end of the outdoor shoji frame 20 join to form the fitting joint. The thermal insulation structure at the joint of the fitting according to this application is provided at the left end of the indoor shoji frame 10 and the right end of the outdoor shoji frame 20.

[0033] As shown in Figures 3 and 4, the heat-insulating structure at the joint of the fittings according to the present application includes an inside joint portion 11 provided at the left end of the indoor shoji screen 10, and an outside joint portion 21 provided at the right end of the outdoor shoji screen 20. Here, the inside joint portion 11 includes an indoor shoji screen member 30 for the indoor shoji screen member on the left side of the indoor shoji screen 10, and an inside insulating cover 40 attached to the outdoor end face (i.e., the front end face) of the indoor shoji screen member 30 for the indoor shoji screen member, and a first hook portion 41 extending to the right is provided on the front side of the inside insulating cover 40. The exterior joint section 21 includes an exterior joint section shoji profile 50 on the right side of the exterior shoji screen 20 and an exterior insulating cover 60 attached to the interior end face (i.e., rear end face) of the exterior joint section shoji profile 50. A second hook section 51 extending toward the left is provided on the rear side of the exterior joint section shoji profile 50 or the exterior insulating cover 60. Of the interior joint section shoji profile 30 and the exterior joint section shoji profile 50, if at least the interior joint section shoji profile 30 is an insulating bridge profile, the exterior joint section shoji profile 50 may be an insulating bridge profile or a regular profile. An insulating bridge profile is a profile with insulating material fixed inside.

[0034] When the indoor shoji screen 10 and the outdoor shoji screen 20 are opened, i.e., when the fittings are open, the first hook portion 41 and the second hook portion 51 are separated, and the first hook portion 41 is located to the left of the second hook portion 51. When the indoor shoji screen 10 and the outdoor shoji screen 20 are closed, i.e., when the fittings are closed, as shown in Figures 3 and 4, the first hook portion 41 is located on the outdoor side (i.e., in front) of the second hook portion 51, and at least a portion of the first hook portion 41 and the second hook portion 51 face each other front to back in the indoor / outdoor direction, but the first hook portion 41 and the second hook portion 51 do not come into contact, making it easy to open the indoor shoji screen 10 and the outdoor shoji screen 20. Furthermore, when the indoor shoji screen 10 and the outdoor shoji screen 20 are closed, the indoor joint portion 11 and the outdoor joint portion 21 face each other in the front-to-back direction, i.e., the indoor shoji screen shape member 30, the indoor insulating cover 40, the outdoor insulating cover 60 and the outdoor shoji screen shape member 50 are positioned facing each other from back to front in the direction from inside the room to outside the room. In this way, at the joints of the fixtures, heat from the inside of the room can flow to the outside by passing through the indoor joint shoji shape 30, the inner insulating cover 40, the outer insulating cover 60, and the outdoor joint shoji shape 50 in that order, but in the indoor joint shoji shape 30, the inner insulating cover 40, the outer insulating cover 60, and the outdoor joint shoji shape 50, at least the indoor joint shoji shape 30, the inner insulating cover 40, and the outer insulating cover 60 act as heat barriers and insulators, effectively preventing heat from being transmitted from inside the room to the outside and realizing insulation at the joints of the fixtures.

[0035] Naturally, the insulation structure at the joint of the building materials in this application is a multi-layer insulation structure in the indoor and outdoor directions, and the insulation measures are at least an insulating bridge profile and double insulating covers inside and outside, and this multi-layer insulation structure has the following advantages: 1. It effectively reduces heat loss at the joints and greatly improves the insulation capacity of the joints, which is beneficial to the promotion of energy-saving and environmental protection policies, meets the increasing demand for strict energy conservation in the construction industry, and enhances the product competitiveness of building materials. 2. The inner insulating cover 40 and the outer insulating cover 60 are located between the indoor joint shoji profile 30 and the outdoor joint shoji profile 50, which increases the insulating capacity and increases the distance between the indoor joint shoji profile 30 and the outdoor joint shoji profile 50 in the indoor / outdoor direction, slowing down heat loss and making the indoor joint shoji profile 30 less susceptible to condensation, improving the product performance of the building materials. 3. By improving the insulation capacity of the joints, the insulation coefficient of the entire building material can be effectively reduced, and the application area of ​​the building material can be expanded in the northern region. 4. Improving the insulation capacity of the joints effectively increases the energy-saving effect of the entire building, and allows the overall size and area of ​​the building to be expanded with a given amount of energy consumption, thereby increasing the view and lighting in the room. 5. The inner heat insulating cover 40 and the outer heat insulating cover 60 are located between the indoor joint shoji frame 30 and the outdoor joint shoji frame 50, and are not exposed to the exterior of the fixture, thereby ensuring the appearance of the fixture.

[0036] Furthermore, in this embodiment, both the inner insulating cover 40 and the outer insulating cover 60 are made of resin profiles, and the material of the resin profiles is preferably rigid PVC. The inner insulating cover 40 and the outer insulating cover 60 made of resin profiles can effectively suppress heat conduction and further improve the insulating ability at the joints of the building components. Of course, in other embodiments, the material of the inner insulating cover 40 and the outer insulating cover 60 may be PA66 insulating material.

[0037] 4, 5, and 8, the indoor-side joint shoji profile 30 is an insulating bridge aluminum profile, and the outdoor-side joint shoji profile 50 is a regular aluminum profile. Therefore, only the insulating material is fixed inside the indoor-side joint shoji profile 30, and there is no insulating material inside the outdoor-side joint shoji profile 50. The indoor-side insulating bridge aluminum profile, the inner insulating cover 40, and the outer insulating cover 60 already provide excellent insulation at the joint. That is, the heat transfer coefficient obtained by the multi-layer insulating structure formed by the indoor-side insulating bridge aluminum profile, the inner insulating cover 40, the outer insulating cover 60, and the outdoor-side regular aluminum profile is very close to the heat transfer coefficient obtained by the multi-layer insulating structure formed by the indoor-side insulating bridge aluminum profile, the inner insulating cover 40, the outer insulating cover 60, and the outdoor-side insulating bridge aluminum profile. In this way, the present application ensures effective insulation, reduces costs, and enhances the overall competitiveness of the product simply by using an insulating bridge aluminum profile for the indoor-side joint section 30 and a regular aluminum profile for the outdoor-side joint section 50. Based on this structure, the insulating structure at the joint section of the fittings of the present application is a multi-layered insulating structure that combines multiple insulating technologies, consisting of an insulating bridge aluminum profile on the indoor side, a hard PVC resin material on the inside, a hard PVC resin material on the outside, and a regular aluminum profile on the outside, achieving the best insulating effect.

In addition, the first insulating material 36 and the second insulating material 37 are perpendicular to each other, and by using a 90° thermal break structure of the insulating material for the insulating bridge shape that makes up the indoor side joint shoji shape 30, the insulating effect is improved and the insulating capacity at the joint of the building materials is further increased.

[0039] Preferably, as shown in Figures 4 and 5, an insulating bridge cavity 38 is formed between the main section 31 and auxiliary section 32 of the indoor-side joint shoji section 30. The insulating bridge cavity 38 is located on the inner periphery of the first insulating material 36 and the second insulating material 37, and the indoor-side joint shoji section 30 has insulating foam material 80 provided within the insulating bridge cavity 38, thereby further improving the insulating capacity at the joint of the fittings.

Here, the inner cover vertical portion 42 and the shaped member auxiliary member 32, and the second inner cover horizontal portion 44 and the second connecting portion 312 are all fitted and fixed, so that the inner insulating cover 40 is attached to the front side of the shaped member auxiliary member 32 and the second connecting portion 312 of the indoor-side joint shoji screen member 30. The first hook portion 41 extends to the right from the front end of the inner cover vertical portion 42 in a direction away from the second inner cover horizontal portion 44, so that the first hook portion 41 is located on the outdoor side of the first inner cover horizontal portion 43. The second inner cover horizontal portion 44 is located on the front side of the second insulating material 37 and is close to the second insulating material 37. The right end of the first inner cover horizontal portion 43 extends beyond the left end of the first shoji panel material 120 to the right, and when the fixture is closed, the right end of the first inner cover horizontal portion 43 is flush with the right end of the exterior joint shoji shape material 50, and the left end of the second inner cover horizontal portion 44 is flush with the left end of the interior joint shoji shape material 30.As a result, the first inner cover horizontal portion 43 and the second inner cover horizontal portion 44 can effectively cover the interior joint shoji shape material 30 and the exterior joint shoji shape material 50 in the left-right direction, reliably guaranteeing insulation effects.

[0041] Furthermore, the fitting structure between the indoor joint shoji profile 30 and the inner insulation cover 40 is preferably, as shown in Figures 5 to 7, such that a first fitting protrusion 45 protruding to the left is provided at the rear end of the inner cover vertical portion 42, a first fitting groove 33 for accommodating the first fitting protrusion 45 is provided on the right side of the profile auxiliary member 32, a second fitting protrusion 46 protruding to the left and a second fitting groove 47 adjacent to the front side of the second fitting protrusion 46 are provided at the left end of the second inner cover horizontal portion 44, and a third fitting groove 34 for accommodating the second fitting protrusion 46 and a third fitting protrusion 35 accommodated in the second fitting groove 47 and protruding to the right are provided on the right side of the second connection portion 312. In particular, there is a first movement gap between the first fitting protrusion 45 and the groove wall of the first fitting groove 33, between the second fitting protrusion 46 and the groove wall of the third fitting groove 34, and between the third fitting protrusion 35 and the groove wall of the second fitting groove 47, and the first movement gap allows the inner insulation cover 40 to movably fit into the profile main member 31 and the profile auxiliary member 32. The movable fitting structure of the inner insulation cover 40 allows the inner insulation cover 40 to better thermally expand and contract at different heating temperatures during the insulation process, further improving the insulation capacity at the joints of the building materials.

[0042] Preferably, as shown in Figures 5 to 7, the second inner cover horizontal portion 44 has a two-layer structure, inner and outer, in the indoor / outdoor direction, forming an internal cover space 441 within the second inner cover horizontal portion 44, thereby further enhancing the insulating capacity at the joints of the building fixtures.

Here, the outer cover vertical portion 61 and the outdoor shoji screen member 50 at the outdoor joint, and the second outer cover horizontal portion 63 and the third connecting portion 52 are all fitted and fixed together, so that the outer insulating cover 60 is attached to the rear side of the outdoor shoji screen member 50 at the outdoor joint. The left end of the first outer cover horizontal portion 62 extends beyond the right end of the second shoji panel material 140 to the left, and when the fixture is closed, the left end of the first outer cover horizontal portion 62 and the left end of the indoor-side joint shoji shape material 30 are flush with each other, so that the first outer cover horizontal portion 62 and the second outer cover horizontal portion 63 can effectively cover the outdoor-side joint shoji shape material 50 and the indoor-side joint shoji shape material 30 in the left-right direction, reliably guaranteeing insulation effects.

[0045] Furthermore, the fitting structure between the outdoor joint shoji frame 50 and the outdoor insulation cover 60 is preferably such that, as shown in Figures 8 to 10, a fourth fitting protrusion 64 protruding to the right is provided at the front end of the outdoor joint shoji frame 50, a fourth fitting groove 53 that accommodates the fourth fitting protrusion 64 is provided at the left end of the outdoor joint shoji frame 50, a fifth fitting protrusion 65 that protrudes to the right is provided at the right end of the second outdoor cover horizontal portion 63, away from the outdoor cover vertical portion 61, and a fifth fitting groove 54 that accommodates the fifth fitting protrusion 65 is provided on the left side of the third connection portion 52. In particular, there is a second movement gap between the fourth fitting protrusion 64 and the groove wall of the fourth fitting groove 53, and between the fifth fitting protrusion 65 and the groove wall of the fifth fitting groove 54, and the second movement gap allows the outer insulation cover 60 to be movably fitted into the outdoor-exterior joint shoji frame member 50. The movable fitting structure of the outer insulation cover 60 allows the outer insulation cover 60 to better undergo thermal expansion and contraction at different heating temperatures during the insulation process, further improving the insulation capacity at the joint of the building materials.

[0046] Furthermore, as shown in Figures 4 and 5, the insulation structure at the joint of the building materials further includes a first sealing material 71 and a second sealing material 72, and when the first sealing material 71 is fixed to the outside of the inner joint portion 11, specifically to the left end of the front surface of the second inner cover horizontal portion 44 of the inner insulation cover 40, the first sealing material 71 is arranged close to the left end of the indoor shoji screen 10 along the width direction of the indoor shoji screen 10, and when the second sealing material 72 is fixed to the inside of the outer joint portion 21, specifically to the right end of the rear surface of the outdoor shoji screen profile 50, the second sealing material 72 is arranged close to the right end of the outdoor shoji screen 20 along the width direction of the outdoor shoji screen 20. When the indoor shoji screen 10 and the outdoor shoji screen 20 are closed, the first sealant 71 abuts against the outer surface (i.e., the rear surface) of the outer insulating cover 60 at the outer joint 21, and the second sealant 72 abuts against the outer surface (i.e., the front surface) of the inner insulating cover 40 at the inner joint 11. In this way, by adding two sealants between the inner joint 11 and the outer joint 21, the flow of cold air and warm air between the inside and outside of the room is effectively prevented.

[0047] Furthermore, as shown in Figures 1 and 3, if the right-side vertical member in the outer frame 90 is defined as the first vertical frame 91 and the left-side vertical member in the outer frame 90 is defined as the second vertical frame 92, the second vertical frame 92 and the first vertical frame 91 are arranged opposite each other on the left and right sides along the width direction of the building fixture, and are located on both the left and right sides of the indoor shoji screen 10 and the outdoor shoji screen 20, respectively.

The indoor shoji frame 110 is an insulating bridge frame, and has two fourth insulating materials 111 arranged side by side along the width direction of the indoor shoji 10 and extending from front to back, with insulating foam material 80 provided between the two fourth insulating materials 111. Additionally, insulating foam material 80 is provided between the right side of the first shoji panel 120 and the indoor-side shoji frame 110, and between the left side of the first shoji panel 120 and the indoor-side joint shoji frame 30.

Additionally, insulating foam material 80 is provided between the left side of the second shoji panel 140 and the outdoor shoji frame 130, and between the right side of the second shoji panel 140 and the outdoor joint shoji frame 50. In the front-to-back direction, the insulating foam material 80 provided on the right side of the first shoji panel 120 covers the fourth insulating material 111, the insulating foam material 80 provided on the left side of the first shoji panel 120 covers the first insulating material 36, the insulating foam material 80 provided on the right side of the second shoji panel 140 covers a part of the outer cover vertical portion 61 of the outer insulating cover 60, and the insulating foam material 80 provided on the left side of the second shoji panel 140 covers the fifth insulating material 131. When the indoor-side shoji panel 10 and the outdoor-side shoji panel 20 are closed, the outer peripheral region of the third insulating material 933 on the left side of the first vertical frame 91 communicates with the outer peripheral region of the fourth insulating material 111 on the right side of the indoor-side shoji frame 110, and the outer peripheral region of the third insulating material 933 on the right side of the second vertical frame 92 communicates with the outer peripheral region of the fifth insulating material 131 on the left side of the outdoor shoji frame 130. In this way, the dashed lines in Figure 3 are the insulation lines of the building fixtures, and it is clear that there are multiple insulation lines in a row, which allows the building fixtures to achieve a continuous insulation line, greatly reducing heat loss and ensuring the insulation coefficient of the entire window.

[0049] Preferably, the first insulating material 36, the second insulating material 37, the third insulating material 933, the fourth insulating material 111, and the fifth insulating material 131 according to the present application are all PA66 insulating materials, which have the effect of suppressing radiation and convection.

[0050] 3, the third insulating material 933 on the left side of the first vertical frame 91 is provided with a first seal abutment portion 94 extending to the left, a third seal material 73 is fixed to the inner surface of the rear edge of the indoor frame body 931 of the first vertical frame 91, a second seal abutment portion 112 extending to the right is provided at the rear edge of the indoor shoji frame member 110, and a fourth seal material 74 is fixed to the inner surface of the right end of the front edge of the indoor shoji frame member 110. When the indoor shoji frame 10 is closed, the third seal material 73 abuts against the rear surface of the second seal abutment portion 112, and the fourth seal material 74 abuts against the front surface of the first seal abutment portion 94. In this way, two seals are formed in the indoor / outdoor direction between the indoor shoji screen 10 and the first vertical frame 91, and these two seals are located on both the front and back sides of the communication area between the third insulating material 933 on the left side of the first vertical frame 91 and the fourth insulating material 111 on the right side of the indoor shoji screen profile 110, thereby effectively preventing the flow of cold and warm air between the indoor and outdoor spaces and reducing heat loss.

[0051] 3, the third insulating material 933 on the right side of the second vertical frame 92 has an insulating extension extending to the right, and a fifth sealing material 75 is fixed to the front surface of the insulating extension. The third seal abutment 95 extending to the right is provided on the right side of the exterior frame body 932 of the second vertical frame 92. The rear edge of the exterior shoji frame 130 has a fourth seal abutment 132 extending to the left, and a sixth sealing material 76 is fixed to the inner surface of the left end of the front edge of the exterior shoji frame 130. When the exterior shoji frame 20 is closed, the fifth sealing material 75 abuts against the rear surface of the fourth seal abutment 132, and the sixth sealing material 76 abuts against the front surface of the third seal abutment 95. In this way, two seals are formed in the indoor / outdoor direction between the outdoor shoji screen 20 and the second vertical frame 92, and these two seals are located on both the front and rear sides of the communication area between the third insulating material 933 on the right side of the second vertical frame 92 and the fifth insulating material 131 on the left side of the outdoor shoji screen profile 130, thereby effectively preventing the flow of cold and warm air between the indoor and outdoor areas and reducing heat loss.
