Description

Technical Field

[0001] The invention relates to the technical field of passive window installation, in particular to a low-energy consumption external passive window installation structure. Background Art

[0002] Passive doors and windows usually refer to door and window systems that do not require external power or human intervention. Their operation mainly relies on natural forces, physical structures or environmental changes, and realizes some automated and intelligent functions, which improves the convenience and efficiency of the door and window system. This type of door and window system is designed with more emphasis on convenience, safety and energy saving. Building energy consumption is divided into two major energy consumptions, namely construction energy consumption and operating energy consumption. While pursuing strict calculation results to reduce operating energy consumption or relevant technical standards, the construction energy consumption of the building cannot be ignored.

[0003] For example, "CN117403990A" is an external passive window installation structure for the renovation of existing buildings, which includes a window frame and a clamping assembly. The clamping assembly is installed on the window frame, and the clamping assembly includes a sliding plate, a fixed claw and a rotating claw. The sliding plate is fixedly connected to the window frame, and a fixed sliding groove is provided in the fixed claw. The sliding plate is inserted in the fixed sliding groove, and the length of the sliding plate is less than the length of the sliding groove. The rotating claw is rotatably connected to the fixed claw, and a rotating sliding groove is provided on the rotating claw. When the rotating claw is rotated to be in the same plane as the fixed claw, the fixed sliding groove is connected to the rotating sliding groove, so that the sliding plate slides into the rotating sliding groove. The window frame is fixed by limiting the fixed claw and the rotating claw, thereby avoiding drilling holes in the walls of old buildings and avoiding installing the window frame while damaging the walls of old buildings. The present application has the effect of facilitating the installation of passive windows on old buildings;

[0004] In order to achieve the goal of energy conservation and carbon reduction, higher requirements are placed on the energy-saving efficiency of buildings. However, the actual external window installations in current projects all use homemade all-metal materials, which cannot achieve insulation conditions. A large number of cold and hot bridges are formed between the external windows and the main walls, which is fatal to buildings with strict requirements for energy conservation. Summary of the invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that a self-made all-metal exterior window cannot achieve insulation conditions when installed externally, a large number of cold and hot bridges are formed between the exterior window and the main wall, causing a large amount of heat loss.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a low-energy consumption external passive window installation structure, which includes a support bracket for supporting a window body and a fixing member for positioning the side and top of the window body, a window frame is provided on the outside of the window body, and the window frame is assembled and connected to the outside of a structural wall through the support bracket and the fixing member respectively, a window groove for installing the window body is provided on the structural wall, and a thermal insulation layer is provided on the outside of the structural wall, the support bracket is assembled and connected to the structural wall below the window groove through a first expansion bolt, the fixing member is arranged in an L-shaped structure, one side of the fixing member is assembled and connected to the top and side of the window frame through a self-tapping screw, the fixing member is provided with an installation groove for inserting the self-tapping screw, and there are multiple installation grooves, the other side of the fixing member is assembled and connected to the structural wall through a gasket, and one side of the fixing member is assembled and connected to the structural wall through a second expansion bolt, the window frame is provided with a thermal insulation member on the outside, the fixing member, the support bracket and the window frame are all located inside the thermal insulation member, the side wall of the thermal insulation member is assembled and connected to the thermal insulation layer, and a waterproof and air-proof film is laid between the structural wall at the window groove and the inner side of the window body.

[0009] Furthermore, the gasket is assembled and connected to the outer side of one side of the fixing part, one end of the gasket is set to be of the same length as the end face of the fixing part, the sum of the thickness of the window frame and the height of the fixing part is adapted to the length of the gasket, and during installation, the end face of the gasket is just located on the structural wall at the window groove, which can just separate the structural wall from the window frame and the fixing part to avoid heat transfer.

[0010] Furthermore, the fixing part is a galvanized part, the gasket is a high-strength polyurethane gasket, and the thermal conductivity of the high-strength polyurethane is 0.02-0.04 W / (m·K).

[0011] Furthermore, a bolt hole is provided on the outer side of the support bracket, and one end of the first expansion bolt passes through the bolt hole and penetrates the support bracket to be assembled and connected with the structural wall, and the provided bolt hole is used to accommodate the end face of the first expansion bolt.

[0012] Furthermore, the outer side of the insulation component is flush with the outer side of the insulation layer, and the inner side of the insulation component is bonded to the surface of the fixing component, the end face of the second expansion bolt, the end face of the self-tapping screw, the outer wall of the window frame and the insulation layer through an adhesive layer.

[0013] Furthermore, one end of the thermal insulation component connected to the window frame completely covers the outer wall of the window frame, thereby reducing the contact between the window frame and the external environment, thereby further avoiding the thermal bridge effect between the structural wall and the window frame.

[0014] Furthermore, the first expansion bolt and the second expansion bolt are both low thermal conductivity expansion bolts. Since the expansion bolts installed in the prior art are usually made of metal, the metal material directly penetrates between the fixing parts and the structural wall. The heat in the structural wall will be conducted to the metal fixing parts through the metal bolts, thereby forming an obvious thermal bridge effect and causing rapid heat loss. The low thermal conductivity expansion bolts can effectively prevent this from happening.

[0015] Furthermore, the waterproof and air-barrier membrane is laid at the corner connection between the structural wall and the window in the window groove. The waterproof and air-barrier membrane can effectively improve the air tightness and waterproof performance, prevent heat loss, moisture penetration and condensation, reduce the influence of thermal bridge effect on thermal insulation performance, and at the same time protect the structural wall and insulation parts, thereby extending the service life of the window groove connection.

[0016] Furthermore, a waterproof layer is laid at a corner of one end where the outer wall of the thermal insulation component is connected to the window frame, and one end of the waterproof layer is assembled and connected to the window body. The waterproof performance of the window body is ensured by the provision of the waterproof layer.

[0017] Furthermore, a waterproof slope is provided between the end face of the waterproof layer at the lower end of the window groove and the window body, and a rain edge is provided below the waterproof layer at the upper end of the window groove. The rain edge is inclined outward at 30 degrees. The waterproof slope can avoid the problem of water accumulation at the connection between the waterproof layer and the window body causing reduced sealing of the window body. Most of the rainwater can be drained to the outside through the rain edge, reducing the situation where rainwater flows into the lower connection.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention adopts high-strength polyurethane material as a gasket between the L-shaped galvanized fixing part and the wall. The gasket is integrated with the L-shaped galvanized fixing part as a part connecting the fixing part and the main body. The gasket made of high-strength polyurethane material can effectively eliminate the formation of cold bridges and form insulation conditions. It is suitable for cantilever installation of external windows of ultra-low energy consumption, near-zero energy consumption, zero energy consumption and other buildings, improves the thermal insulation performance of the external windows, and avoids the formation of cold bridges at the junction of the external windows and the wall.

[0020] 2. The present invention provides a plurality of installation grooves on one side of the fixing member, thereby facilitating fine-tuning of the distance between the window frame and the structural wall, making installation more convenient.

[0021] 3. In the present invention, both the first expansion bolt and the second expansion bolt are low thermal conductivity expansion bolts. The low thermal conductivity expansion bolts can effectively reduce the thermal bridge effect formed by the heat of the structural wall being conducted to the metal fixings through the metal bolts.

[0022] 4. The thermal insulation component and the thermal insulation layer of the present invention are seamlessly bonded and connected to ensure the continuity of the thermal insulation structure and reduce the loss of indoor heat. In addition, the gasket provided on one side of the fixing component is made of high-strength polyurethane material, which can effectively reduce the heat conduction efficiency of the window frame.

[0023] 5. The thermal insulation component of the present invention covers and wraps all the fixing components and the edges of the window frame, thereby reducing the contact between the window frame and the external environment, thereby further avoiding the thermal bridge effect between the structural wall and the window frame.

An insulation part 13 is provided on the outside of the window frame 4, and the fixing part 3, the support bracket 2 and the window frame 4 are all located inside the insulation part 13. The side wall of the insulation part 13 is assembled and connected to the insulation layer 7, and a waterproof and air-proof membrane 14 is laid between the structural wall 5 at the window groove 6 and the inner side of the window 1.

[0036] like Figure 1-Figure 5 As shown, the gasket 11 is assembled and connected to the outer side of one side of the fixing member 3, one end of the gasket 11 is set to be equal in length to the end face of the fixing member 3, the sum of the thickness of the window frame 4 and the height of the fixing member 3 is adapted to the length of the gasket 11, and during installation, the end face of the gasket 11 is just located on the structural wall 5 at the window groove 6, which can just separate the structural wall 5 from the window frame 4 and the fixing member 3 to avoid heat transfer.

[0037] like Figure 1-Figure 5 As shown, the fixing part 3 is a galvanized part, and the gasket 11 is a high-strength polyurethane gasket 11, and the thermal conductivity of the high-strength polyurethane is 0.02-0.04 W / (m·K).

[0038] like Figure 1-Figure 5As shown, a bolt hole 15 is provided on the outer side of the support bracket 2, and one end of the first expansion bolt 8 passes through the bolt hole 15 and penetrates the support bracket 2 to be assembled and connected with the structural wall 5. The provided bolt hole 15 is used to accommodate the end face of the first expansion bolt 8.

[0039] like Figure 1-Figure 5 As shown, the outer side of the insulation member 13 is flush with the outer side of the insulation layer 7, and the inner side of the insulation member 13 is bonded to the surface of the fixing member 3, the end face of the second expansion bolt 12, the end face of the self-tapping screw 9, the outer wall of the window frame 4 and the insulation layer 7 through the adhesive layer 16.

[0040] like Figure 1-Figure 5 As shown, one end of the thermal insulation member 13 connected to the window frame 4 completely covers the outer wall of the window frame 4, thereby reducing the contact between the window frame 4 and the external environment, thereby further avoiding the thermal bridge effect between the structural wall 5 and the window frame 4.

[0041] like Figure 1-Figure 5 As shown, the first expansion bolt 8 and the second expansion bolt 12 are both low thermal conductivity expansion bolts. Since the expansion bolts installed in the prior art are usually made of metal, the metal material directly penetrates between the fixing member 3 and the structural wall 5. The heat in the structural wall 5 will be conducted to the metal fixing member 3 through the metal bolts, thereby forming an obvious thermal bridge effect, causing rapid heat loss. The low thermal conductivity expansion bolts can effectively prevent this from happening.

The rain edge 19 is inclined outward at 30 degrees. The waterproof slope 18 is provided to avoid the problem of water accumulation at the connection between the waterproof layer 17 and the window body 1 causing reduced sealing of the window 1. The rain edge 19 can drain most of the rainwater to the outside, reducing the situation where rainwater flows into the connection below.

[0045] Working principle: When installing the window 1, first place the support bracket 2 on the outside of the structural wall 5 below the window groove 6, and fix it to the structural wall 5 with the first expansion bolt 8, and then face the side of the plurality of fixings 3 with gaskets 11 toward the structural wall 5, and use the second expansion bolt 12 to fix it to the structural wall 5, and place the window frame 4 on the outside of the window 1 stably on the support bracket 2, and the outer wall of the window frame 4 just slides and fits with the side of the plurality of fixings 3 away from the structural wall 5. At this time, the self-tapping screws 9 are used to penetrate the fixings 3 and assemble the window frame 4. By setting a plurality of installation grooves 10 on one side of the fixings 3, it is convenient to adjust the installation position of the self-tapping screws 9 between the window frame 4 and the corresponding fixings 3, so as to achieve the purpose of fine-tuning the distance between the window frame 4 and the structural wall 5, and assemble After that, an insulation member 13 is sleeved on the outer wall of the window frame 4, so that the insulation member 13 covers and wraps all the fixing members 3 and the edges of the window frame 4, and the insulation member 13 is seamlessly glued and connected to the insulation layer 7 to ensure the continuity of the insulation structure and reduce the loss of indoor heat. In addition, a gasket 11 is arranged on one side of the fixing member 3, wherein the gasket 11 is made of high-strength polyurethane material, which can effectively reduce the thermal conduction efficiency of the window frame 4, and provides a huge supporting effect for the realization of ultra-low energy consumption, near-zero energy consumption, zero energy consumption and other buildings. In addition, the gasket 11 only exists on one side in contact with the fixing member 3 and the structural wall 5, while the gasket 11 is not arranged on the other side, which not only directly blocks the direct contact between the structural wall 5 and the fixing member 3 and the window frame 4, but also saves the cost of the gasket 11, and has the advantages of simple materials, low cost and low manufacturing difficulty.
