[0002] The door and window for super-low-energy buildings, also known as passive door and window, is mainly composed of door and window profiles, glass forms, hardware and heat insulation sealing strips. The door and window profiles are mainly made of plastic steel profiles to manufacture and process door and window frames, the configured glass is vacuum Low-E sunshade fully tempered glass, and the hardware and heat insulation sealing strips are selected from products of high quality in the door and window industry to assist the passive door and window. The high configuration materials meet the requirements of passive house high-standard energy-saving door and window and door and window installation.

[0003] The traditional passive door and window structure is assembled by plastic steel or aluminum alloy profiles with multiple sealing strips in the middle. The multiple sealing strips separate the inner and outer profiles to achieve good thermal insulation and air tightness. Thus, the passive door and window is heavy and the structure is complex. Meanwhile, most of the existing passive door and window structures adopt an external hanging structure. The external hanging structure needs to be fixed and installed after being delivered to the installation position. The delivery process is prone to damage. The delivery method is labor-intensive.

[0004] Therefore, there is an urgent need for a super-low-energy door and window structure that is easy to install and has good thermal insulation and air tightness. SUMMARY

[0005] The application aims to solve the problems in the prior art. The door and window structure for super-low-energy buildings and the construction method are proposed. The inner frame and the outer frame are connected by the connecting piece, and the two have a certain pulling effect to ensure that the glass is stably clamped between them. The connecting piece and the heat preservation structure can form a heat insulation bridge structure between the inner frame and the outer frame, form several sealing structures, ensure the practicability of the super-low-energy building, and have good thermal insulation and air tightness. The structure of the application is simpler than the previous door and window structure, the weight is greatly reduced, and the installation steps are also simpler.

[0006] To achieve the above purpose, the application adopts the following technical solutions:

[0007] The utility model provides a kind of door and window structure for ultra-low energy consumption building, including installation in the interior of aperture outer frame and inner frame, outer frame and inner frame relative side are provided with for installing multilayer glass containing area, the outer frame and inner frame between containing area peripheral area are installed with connecting piece, when inner frame and outer frame are connected by connecting piece, present mutual pulling state, connecting piece installation area peripheral and the outer frame and inner frame between containing area and connecting piece installation area are provided with heat preservation structure, heat preservation structure is suitable for effect connecting piece keeps pulling state while separating outer frame and inner frame and cooperates connecting piece to form heat insulation bridge structure, inner frame, outer frame outer edge portion and aperture are installed with sealing structure between, sealing structure includes moisture-proof heat insulation pad, connecting plate and waterproof air barrier film sequentially arranged from aperture side wall to inner frame, outer frame outer edge, connecting plate is installed in aperture by expansion bolt and penetrates moisture-proof heat insulation pad, waterproof air barrier film is arranged between inner frame, outer frame outer edge area and connecting plate, sealing structure also includes sealing glue that wraps moisture-proof heat insulation pad, connecting plate and waterproof air barrier film outer side end and wraps moisture-proof heat insulation pad, connecting plate inner side end.

[0008] In use, connecting piece is installed between inner frame and outer frame, by inner frame and outer frame mutually close, after inner frame and outer frame mutually close certain distance, connecting piece can pull effect to inner frame and outer frame, automatically hold multilayer hollow glass in containing area, ensure the stability and safety of door and window structure before installing sealing structure and relevant finish layer, connecting piece and heat preservation structure are made of moisture-proof heat insulation material, after installation, heat preservation structure forms heat insulation bridge structure in inner frame and outer frame cooperates connecting piece, forms several sealing structures, ensure the airtightness and heat preservation of structure, in turn ensure the heat insulation and heat preservation effect of door and window, the structure and installation step of the scheme are simple and easy to operate, more practical, lower economic cost, heat preservation structure effect connecting piece keeps pulling effect to ensure the double stability and reliability of structure.

[0009] Further scheme, the relative side of outer frame and inner frame is provided with connecting groove, the both ends of connecting piece are provided with flexible connecting structure respectively and the end of flexible connecting structure can freely enter corresponding connecting groove.In, flexible connecting structure needs to be extruded close to each other when entering connecting groove, after entering connecting groove, it is formed hooking effect with connecting groove by its elasticity.Flexible connecting structure expands to both sides and forms hooking area with the slot position of connecting groove, in turn can ensure the sealing installation effect of inner frame and outer frame.

[0010] Further, the connecting piece includes a deformation part one, a deformation part two and a hooking part. The deformation part one is integrally connected between two hooking parts for connecting the inner frame or the outer frame. The deformation part two is integrally connected between two hooking parts for connecting the inner frame and the outer frame. The deformation part one and the hooking parts at both ends of the deformation part one form a flexible connecting structure. When the connecting piece connects the inner frame and the outer frame, the bending angle of the deformation part one decreases, and the bending angle of the deformation part two increases inwardly and is greater than 180°. The two hooking parts of the deformation part one are pressed against each other, the bending angle of the deformation part one increases, and after the hooking parts enter the connecting groove, the deformation part one first drives the hooking parts to abut against the upper side and the lower side of the connecting groove under the condition of elastic deformation of the deformation part one. The deformation part one still has a tendency to restore the initial state and will have a tendency to drive the two ends to spread outwardly to push the hooking parts to the side of the slot opening. The hooking parts are preliminarily hooked and fixed to the slot opening position of the connecting groove. At the same time, the deformation part two will gradually increase the bending angle and tend to present a stable form as the distance between the inner frame and the outer frame decreases. The ends of the deformation part two will press the end portions of the hooking parts to the two sides. In cooperation with the deformation part one, the hooking parts and the slot opening position of the connecting groove will achieve a strong hooking effect. The materials of the deformation part one, the deformation part two and the hooking part are consistent. The thickness of the deformation part one gradually increases from the middle to both ends. The thickness of the deformation part two gradually increases from the middle to both ends. The thickness of the hooking part is consistent and is the largest among the three.

[0011] Further, the upper part and the lower part of the connecting groove are provided with slope guide structures. When the deformation part one enters the connecting groove, the bending angle decreases outwardly. The hooking parts first abut against the upper part and the lower part of the connecting groove and move towards the opening of the connecting groove along the slope guide structures. The hooking parts form a hooking form with the connecting groove, and the bending angle of the deformation part two increases. In this scheme, during the hooking process of the connecting piece and the inner frame and the outer frame, the hooking parts first move to the two sides. After abutting against the upper part and the lower part of the connecting groove, the hooking parts move towards the side of the slot opening under the action of the deformation part one. At the same time, the deformation part two bends inwardly and increases the bending angle and acts on the hooking parts to rotate by a certain angle. The whole connecting piece pulls the inner frame and the outer frame to approach each other, thereby ensuring the stability and reliability of the hooking structure.

[0012] Further, the connecting piece is provided with an auxiliary pressing piece and an internal support structure inside. The auxiliary pressing piece is suitable for pulling the hooking parts inwardly to tightly adhere to the inner wall of the connecting groove after the connecting piece connects the inner frame and the outer frame. The internal support structure is suitable for outwardly pressing the auxiliary pressing piece and inwardly pulling the two deformation parts two after the connecting piece connects the inner frame and the outer frame.

[0013] Further, the internal support structure includes a circular column in the middle and an outer extrusion sheet and an inner pulling sheet arranged outside the circular column, the outer extrusion sheet is in a curved state in a natural state and in a stable linear state in a working condition, and the inner pulling sheet is in a linear state in a natural state and in a stable curved state in a working condition.

[0014] The auxiliary pressing sheet is in an inner curved state in a natural state, and when the working condition is deformed, one end of the deformation part is extruded outward, the second deformation part is bent inward at a large angle, the hooking part is rotated by a certain angle, the auxiliary pressing sheet is first converted from the inner curved state to the outer curved state and is attached to the outer side of the first deformation part, the outer extrusion sheet is converted from the original curved state to the stable linear state, and the inner pulling sheet is converted from the linear state to the stable curved state, thereby ensuring the stability of the structure.

[0015] Further, the outer frame and the inner frame are provided with slope structures on opposite sides, the heat preservation structure includes a heat preservation gas separation body clamped between the outer frame and the inner frame, the heat preservation gas separation body is provided with mounting structures matched with the slope structures, the slope structures of the outer frame and the inner frame are provided with retreat stop structures one, and the heat preservation gas separation body is provided with retreat stop structures two matched with the retreat stop structures one for installation. The retreat stop structures one and the retreat stop structures two are matched and subjected to the outward thrust of the second deformation part. The heat preservation gas separation body can move from the area between the inner frame and the outer frame to the side close to the connecting piece when the inner frame and the outer frame gradually approach, and will first move to the side close to the second deformation part when entering, and will bend and deform the second deformation part inward to break the stable curved state of the second deformation part when moving to a certain distance, and will drive the hooking part to move a small distance in the slot, so that the retreat stop structures one and the retreat stop structures two are matched to realize locking after the installation of the inner frame and the outer frame, thereby further ensuring the installation stability and reliability of the inner frame and the outer frame.

[0016] A construction method of a door and window structure for ultra-low energy consumption buildings, the construction steps are as follows:

[0017] Step one: before installing the door and window, the following construction is made on the indoor side: the connecting plate is fixed to the hole close to the outer side by penetrating the moisture-proof heat insulation pad with expansion bolts;

[0018] Step two: the waterproof gas separation film is bonded to the outer edge of the outer frame, the outer frame is installed on the connecting plate from the inside to the outside, the connecting piece is installed in the connecting groove on the inner side of the outer frame, and the three-layer hollow glass is placed in the holding area;

[0019] Step 3: Adhere the waterproof and airtight membrane to the outer edge of the inner frame. When installing the inner frame from the inside out, first squeeze the corresponding hook parts on the connectors to bring them closer together until the flexible connection structure of the connectors is fully inserted into the connecting groove. Under its own elasticity, the first deformation part expands to both sides, and the bending angle of the first deformation part decreases. As the inner frame gradually moves towards the outer frame, the second deformation part bends inward at a larger angle, which is greater than 180°. At the same time, the hook part and the connecting groove are hooked together, or the outer extrusion plate changes from a naturally bent state to a stable linear state under working conditions. The inner pull tab changes from a linear state under natural conditions to a stable bending state under working conditions. As the outer frame and inner frame approach each other, the insulation structure gradually approaches the deformation part two. First, it approaches the deformation part two along the guide structure between the inner frame and the outer frame and contacts the deformation part two. Then, it continues to press outward to install the inner frame. The insulation structure deforms the inner top of the deformation part two. Then, under the action of the deformation part two, the anti-retraction structure one and the anti-retraction structure two are matched and locked. Finally, the insulation structure is clamped between the outer frame and the inner frame. At this time, the inner frame and the outer frame are in a state of mutual tension through the connector and in a state of locking through the insulation structure.

[0020] Step Four: The outer side end portions of the moisture-proof and heat-insulating pad, the connecting plate and the waterproof and air-proof film and the inner side end portions of the moisture-proof and heat-insulating pad and the connecting plate are all wrapped and sealed by sealing glue. Figure 1 The waterproof and breathable membrane is then wrapped with sealant on the inside. On the outside of the opening, the waterproof and breathable membrane, insulation board, and window sill are installed in sequence. Foam material is used to fill the gap between the insulation board and the window sill. Finally, the finishing layer is applied to both the outside and inside of the opening.

[0044] In the above embodiment, the following improvements are made: as shown in the drawings, Figure 13 , Figure 14 and Figure 8 As shown in the drawings, the inside of the connecting piece 30 is provided with an auxiliary pressing piece 34 and an internal support structure, the auxiliary pressing piece 34 is suitable for pulling the hooking part 33 of the flexible connecting structure inwardly to tightly adhere to the inner wall of the connecting groove 100 after the connecting piece 30 connects the inner frame 20 and the outer frame 10, and the internal support structure is suitable for outwardly extruding the auxiliary pressing piece 34 and inwardly pulling the two deformation part twos 32 after the connecting piece 30 connects the inner frame 20 and the outer frame 10.

The three-layer hollow glass is placed in the holding area 110;

[0052] Step three: The waterproof and air isolation film 80 is bonded to the outer edge of the inner frame 20. When the inner frame 20 is installed from inside to outside, the flexible connecting structure of the connecting piece 30 first enters the inside of the connecting groove 100. As the distance between the inner frame 20 and the outer frame 10 gradually decreases, the bending angle of the deformed part one 31 decreases, the bending angle of the deformed part two 32 increases inward and is greater than 180°, the hooking part 33 and the connecting groove 100 are in a hooked state, the heat preservation structure 50 moves towards the slot of the connecting groove 100, the outer extruded sheet 36 changes from the bending state in the natural state to the stable linear state in the working condition, and the inner pulling sheet 37 changes from the linear state in the natural state to the stable bending state in the working condition. The heat preservation structure 50 gradually approaches the deformed part two 32 during the approach of the outer frame 10 and the inner frame 20, first completely enters the guide structure between the inner frame 20 and the outer frame 10, deforms inward on the deformed part two 32, and then the stop structure one 12 and the stop structure two 52 are adapted and locked under the action of the deformed part two 32. Finally, the heat preservation structure 50 is clamped between the outer frame 10 and the inner frame 20;

A construction method for a door and window structure for ultra-low energy consumption buildings as described in claim 5, characterized in that, The construction steps are as follows: Step 1: Before installing doors and windows, perform the following construction on the indoor side: fix the connecting plate to the outside of the opening by passing expansion bolts through the moisture-proof and heat-insulating pad; Step 2: Adhere a waterproof and airtight membrane to the outer edge of the outer frame, install the outer frame from the inside out onto the connecting plate, and install the connector in the connecting groove on the inner side of the outer frame. Place the triple-glazed glass in the storage area. Step 3: Adhere the waterproof and airtight membrane to the outer edge of the inner frame. When installing the inner frame from the inside out, first squeeze the corresponding hook parts on the connectors to bring them closer together until the flexible connection structure of the connectors is fully inserted into the connecting groove. Under its own elasticity, the first deformation part expands to both sides, and the bending angle of the first deformation part decreases. As the inner frame gradually moves towards the outer frame, the bending angle of the second deformation part increases and exceeds 180°.

The pull tab changes from a linear state under natural conditions to a stable bending state under working conditions. As the outer frame and inner frame approach each other, the insulation structure gradually approaches the second deformation part. The insulation structure first approaches the second deformation part along the guide structure between the inner frame and the outer frame, and contacts the second deformation part. Then it continues to press outward to install the inner frame. The insulation structure deforms the inner top of the second deformation part. Then, under the action of the second deformation part, the first and second anti-retraction structures are matched and locked. Finally, the insulation structure is clamped between the outer frame and the inner frame. At this time, the inner frame and the outer frame are in a state of mutual tension through the connector and in a locked state through the insulation structure. Step 4: Seal the outer ends of the moisture-proof and heat-insulating pad, connecting plate, and waterproof air-tight membrane, as well as the inner ends of the moisture-proof and heat-insulating pad and connecting plate, with sealant. Wrap the waterproof air-tight membrane with the sealant on the inner side. Install the waterproof breathable membrane, insulation board, and window sill in sequence on the outside of the opening.
