Description

Technical Field

[0001] The present application relates to the technical field of wall insulation, and in particular to an exterior wall composite XPS extruded board insulation system. Background Art

[0002] At present, with the introduction of modern economic concepts and social and economic development concepts, energy conservation and environmental protection have become very important topics in the field of construction. Measures such as adding insulation layers to building exterior walls and using thermal insulation broken bridge structural profiles for door and window frame structures all have one purpose, which is to reduce the temperature difference between indoor and outdoor areas of buildings. The insulation layer usually uses composite XPS extruded board, which is a layer of specific composite material covered on the surface of the XPS substrate, and has high compressive strength, thermal insulation, low water absorption and aging resistance.

[0003] In the prior art, the thermal insulation effect of the building exterior wall is relatively good, and the heat loss is usually caused by the window frame. In order to reduce the heat loss of the window frame, high-quality double-layer or multi-layer window frame glass is usually used to reduce the heat loss; however, there is no corresponding thermal insulation measure at the joint between the insulated building exterior wall and the window frame, and the heat is easily and quickly conducted to the outside, causing heat loss. Summary of the invention

[0004] In order to reduce heat loss at the exterior wall window frame, the present application provides an exterior wall composite XPS extruded board insulation system.

[0005] The present application provides an exterior wall composite XPS extruded board insulation system, which adopts the following technical solutions:

[0006] An exterior wall composite XPS extruded board insulation system, comprising:

[0007] The main wall is formed with reserved window holes;

[0008] A fixed frame is arranged at the reserved window hole, connected to the main wall, and has a snap-in groove on the outside;

[0009] A window frame is arranged at the reserved window hole, the window frame is provided with heat-insulating bolts, the fixing frame is provided with heat-insulating nuts, and the window frame and the fixing frame are detachably connected through the heat-insulating bolts and the heat-insulating nuts;

[0010] A heat insulation board is arranged on the main wall and extends into the clamping groove of the fixing frame;

[0011] A protective layer, disposed on the thermal insulation board via an adhesive layer;

[0012] The heat preservation mechanism comprises a base body arranged on the fixed frame, a first heat preservation board is slidably arranged on the fixed frame, an expansion bag is arranged on the base body, the expansion bag is connected to the first heat preservation board and drives the first heat preservation board to press against the window frame, and the expansion bag is filled with heat preservation expansion material.

[0013] By adopting the above technical scheme, when installing the window frame, a fixing frame is embedded in the wall, and then the window frame is adjusted horizontally and vertically. The window frame is then fixed by tightening the insulation bolts and insulation nuts. The base and the expansion bag are then installed. Then, an expansion insulation layer is formed by filling the expansion bag with insulation expansion material. The expansion bag drives the first insulation board to press against the window frame, reducing the gap between the window frame and the first insulation board. At the same time, the first insulation board and the expansion bag squeeze the window frame to reduce the vibration of the window and the window frame caused by external vibration. The expansion bag is convenient for filling the expansion material densely. Compared with ordinary foaming agents, it is convenient to remove and better fill the gap between the window frame and the wall. It will not overflow due to excessive amount, and can maintain beauty and easy handling. The setting of the expansion bag has a heat insulation effect, and the outer wall of the expanded expansion bag has slight elasticity after expansion, which is convenient to drive the first insulation board to fix the window frame circumferentially, so as to achieve better heat insulation effect, reduce the heat loss from the window frame to the outside, and reduce the generation of cold bridge effect.

[0014] Optionally, a pressing plate is detachably connected to the fixing frame, and the pressing plate is used to fix the window frame and the base. The pressing plate is elastic, and a position abutting against the window frame is bent outward by a reaction force of the window frame.

[0015] By adopting the above technical scheme, after the window frame is installed, the base is then installed and fixed, and the expansion bag and the first insulation board are installed on the base, and the base is fixed with a pressing plate. The end of the pressing plate away from the base is slightly bent in the direction away from the window frame and pressed against the window frame. When the expansion bag expands, it drives the pressing plate to bulge outward, so that the end of the pressing plate presses against the window frame, and the window frame is squeezed and fixed again, further reducing the shaking and vibration of the window frame; and the setting of the pressing plate limits the first insulation board and the expansion bag, and limits their movement direction, so that they can better limit the window frame and maintain the insulation effect.

[0016] Optionally, a plurality of slots are formed on the side wall of the first heat-insulating plate close to the expansion bladder, and a plurality of connecting columns are formed on the expansion bladder, and the connecting columns are inserted into the slots.

[0017] By adopting the above technical solution, when the expansion bag expands, the connecting column expands along with it, so that the first insulation board and the expansion bag form a whole, and the expansion bag expands and squeezes the first insulation board, so that the first insulation board is pressed against the pressure plate and the window frame, so that the gap between the window frame, the pressure plate and the fixed frame can be filled more tightly, and the conduction of heat can be blocked, so that the insulation effect can be improved, and a trapezoidal transition can be formed to reduce the generation of cold bridge effect and reduce the transfer of heat to the wall.

[0018] Optionally, an expansion groove is formed at one end of the slot away from the expansion bag, and the connecting column expands in the expansion groove.

[0019] By adopting the above technical solution, the expansion groove is set, so that the connection between the expanded expansion bag and the first insulation board is tighter after expansion, reducing the possibility of separation, and the setting of the expansion groove makes the expansion bag press against the first insulation board when expanding.

[0020] Optionally, a heat insulation mechanism is provided between the window frame and the fixed frame, and the heat insulation mechanism comprises:

[0021] A plurality of heat-insulating supports are provided, and are located between the window frame and the fixing frame, and are used to reduce the contact between the window frame and the fixing frame;

[0022] An expansion strip is arranged on the fixing frame and abuts against the window frame, and is used for sealing a gap between the fixing frame and the window frame.

[0023] By adopting the above technical scheme, when the window frame is fixed and installed, a heat insulation support is installed between the fixed frame and the window frame, so that the window frame and the fixed frame are not in direct contact, thereby reducing heat loss caused by heat conduction between the frame body of the fixed frame and the frame body of the window frame. At the same time, the expansion strip closes the gap between the window frame and the fixed frame to reduce heat transfer and the entry of water, and can play a certain stabilizing role on the window frame. The heat insulation mechanism, heat insulation bolts, heat insulation nuts, expansion bag and the first insulation board fix the window frame in the circumferential and width directions, making the window frame more firmly fixed. By setting the heat insulation support, expansion bar, first insulation board and expansion bag, the resonance of the window frame driven by the wall can be reduced, the vibration damage to the glass can be reduced, and the stability of the window frame can be increased to improve safety.

[0024] Optionally, a receiving groove is provided on the fixing frame, an elastic groove bar is bonded in the receiving groove, the expansion bar is arranged on the elastic groove bar, and the receiving groove is filled with expansion heat-insulating material.

[0025] By adopting the above technical scheme, when the window frame is driven close to the fixed frame by the heat-insulating bolts and the heat-insulating nuts, the expansion strip is driven by the extrusion force to drive the elastic groove strip to move toward the fixed frame, thereby reducing excessive extrusion of the expansion strip and at the same time reducing the damage to the expansion strip caused by extrusion of the window frame and the fixed frame. When filling the insulation material, the elastic groove strip drives the expansion strip to press against the window frame, so that the sealing effect and partial supporting effect of the expansion strip are kept stable, and the contact between the expansion strip and the window frame is uniform, which can reduce the unevenness of direct contact, extend the service life of the expansion strip and maintain its thermal insulation effect.

[0026] Optionally, a slide groove is provided on the fixing frame, the heat-insulating nut is slidably connected in the slide groove, and the slide groove is filled with a first heat-insulating layer.

[0027] By adopting the above technical scheme, the sliding groove is set to facilitate the installation of window frames with different window frames and different drilling positions, and at the same time it can reduce the installation problems caused by construction errors. By filling the first thermal insulation layer, the first thermal insulation layer further fills the gap between the window frame and the fixed frame, and at the same time can stabilize the window frame and improve the thermal insulation effect. In addition, multiple thermal insulation components further isolate the heat conduction between the window frame, the fixed frame and the outside world, so that the thermal insulation effect is improved and its stability is maintained.

[0028] Optionally, the fixing frame is embedded in the main wall, a filling cavity is formed in the fixing frame, and the filling cavity is filled with a second heat insulation layer.

[0029] By adopting the above technical solution, by filling the second thermal insulation layer in the fixed frame, the fixed frame is further insulated to form multiple barriers to heat loss, thereby improving the thermal insulation effect. At the same time, the elastic groove bars in the accommodating groove are further supported to stabilize the rear end.

[0030] Optionally, a thermal insulation gasket is added at the contact position between the thermal insulation nut and the slide groove, and the thermal insulation gasket slides in the slide groove along the depth direction of the slide groove. A pre-compression plate slides in the accommodating groove, and the pre-compression plate is connected to the thermal insulation gasket.

[0031] By adopting the above technical solution, when connecting the thermal insulation nut and the thermal insulation bolt, the thermal insulation nut approaches the window frame, driving the thermal insulation gasket to approach the window frame, and the thermal insulation gasket drives the pre-compression plate to pre-compress the elastic groove strip in the accommodating groove, thereby reducing the window frame driving the expansion strip to excessively retract into the elastic groove strip, thereby improving the stability of the expansion strip, maintaining the thermal insulation and waterproof effects, and being able to limit the expansion direction of the expansion strip when it expands when encountering water, thereby improving the waterproof effect and thermal insulation effect.

[0032] Optionally, a support assembly is provided on the heat-insulating bolt, and the support assembly includes:

[0033] The rotating head is set at the end of the insulation bolt.

[0034] The support screw is reversely threadedly connected to the end of the insulation nut away from the insulation bolt, and is plugged into the rotating head. An insulation spring is provided at the end away from the rotating head. As the rotating head rotates, the support screw presses the insulation spring tightly into the slide groove.

[0035] By adopting the above technical scheme, when the insulation nut and the insulation bolt are connected, as the insulation bolt rotates, the insulation bolt drives the support screw through the rotating head to tighten in the slide groove, thereby supporting the insulation nut and improving the stability of the insulation nut. It can reduce the activity of the insulation nut when filling the expansion material, and can reduce the chance of the insulation bolt loosening and the window frame shaking, so that the thermal insulation effect can be maintained.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. When installing the window frame, a fixing frame is embedded in the wall, and then the window frame is adjusted horizontally and vertically. Then, the window frame is fixed by tightening the insulation bolts and insulation nuts. Then, the base and the expansion bag are installed. Then, an expansion insulation layer is formed by filling the expansion bag with insulation expansion material. The expansion bag drives the first insulation board to press against the window frame, reducing the gap between the window frame and the first insulation board. At the same time, the first insulation board and the expansion bag squeeze the window frame, reducing the vibration of the window and the window frame caused by external vibration. The expansion bag is convenient for filling the expansion material densely. Compared with ordinary foaming agents, it is convenient to remove and better fill the gap between the window frame and the wall, and it will not overflow due to excessive, so it can maintain beauty and be easy to handle. The setting of the expansion bag has a heat insulation effect, and the outer wall of the expanded expansion bag has slight elasticity after expansion, which is convenient to drive the first insulation board to fix the window frame circumferentially, so as to achieve a better heat insulation effect, reduce the heat loss of the window frame to the outside, and reduce the generation of cold bridge effect.

[0038] 2. When the window frame is driven close to the fixed frame by the heat-insulating bolts and the heat-insulating nuts, the expansion strip is driven by the extrusion force to move the elastic groove strip toward the fixed frame, thereby reducing excessive extrusion of the expansion strip and at the same time reducing the damage of the expansion strip caused by the window frame and the fixed frame. When filling the insulation material, the elastic groove strip drives the expansion strip to press against the window frame, thereby maintaining the sealing effect and partial support effect of the expansion strip stable, and making the contact between the expansion strip and the window frame uniform, thereby reducing the non-uniformity of direct contact, extending the service life of the expansion strip and maintaining its thermal insulation effect;

[0039] 3. When connecting the insulation nut and the insulation bolt, as the insulation bolt rotates, the insulation bolt drives the supporting screw through the rotating head to press against the slide groove, thereby supporting the insulation nut and improving the stability of the insulation nut. This can reduce the movement of the insulation nut when filling the expansion material, and can reduce the chance of the insulation bolt loosening and the window frame shaking, so that the thermal insulation effect can be maintained.

When installing the window frame 300, the surface of the fixed frame 200 is first cleaned, and then the insulation nut 400 is slid into the slide groove 220 through the installation hole 260, and then the elastic groove bar 930 is bonded to the accommodating groove 210, and the expansion bar 920 is installed in the elastic groove bar 930, and then the insulation support 910 is pressed against the window frame 300, and the insulation bolt 500 is passed through the second penetration hole and the first penetration hole, and then the window frame 300 is driven to approach the fixed frame 200, and the insulation bolt 500 and the insulation nut 400 are connected, and then the window frame 300 is slowly opened. The thermal insulation bolt 500 is slowly rotated to fix the window frame 300 on the fixed frame 200. Without tightening the thermal insulation bolt 500, the window frame 300 is adjusted so that the horizontal and vertical directions meet the requirements, and then the thermal insulation bolt 500 is tightened. In the process of tightening the thermal insulation bolt 500, the thermal insulation nut 400 approaches the window frame 300, and the thermal insulation nut 400 drives the thermal insulation gasket 960, the connecting rod 990 and the pre-compression piece 970 to slide. The pre-compression piece 970 squeezes the elastic groove strip 930 so that the expansion strip 920 is pressed against the window frame 300; and in the process of tightening the thermal insulation bolt 500, the thermal insulation bolt 500 drives the rotating head 982 to rotate, and the rotating head 982 drives the support screw 981 and the thermal insulation spring piece 983 to press against the bottom of the groove 220.

[0060] Then, according to the distance between the main wall 100 and the window frame 300, the base 810 is cut, the base 810 is pressed against the fixed frame 200, the pressure plate 840 is pre-installed, and the fixed frame 200 is filled with expansion insulation material, and the filling is carried out from the bottom so that it is fully expanded and rises until the fixed frame 200, the slide groove 220 and the accommodating groove 210 are all filled with expansion insulation material; the pressure plate 840 is removed, and then the expansion bag 820 and the first insulation board 830 are placed between the window frame 300 and the base 810, and then the pressure plate 840 is installed again, and then the expansion bag 820 is filled with expansion insulation material, so that the expansion bag 820 expands and drives the first insulation board 830 to press against the window frame 300, and at this time, the pressure plate 840 is squeezed to increase the pressing force of the pressure plate 840 on the window frame 300.

[0061] Then, the insulation board 600 is installed on the outside of the main wall 100, and the insulation board 600 is snapped into the snap-in groove 250 of the fixed frame 200. Then, the protective layer 700 is installed. After the overall construction on the outside of the main wall 100 is completed, the insulation board 600 and the protective layer 700 are constructed at the position of the pressure plate 840.
