Description

Technical Field

[0001] This invention relates to the field of building renovation technology, and in particular to a window system and construction method that meet the different functional requirements of existing building renovation. Background Technology

[0002] In recent years, due to the rapid development of urbanization in my country and the near saturation of urban construction, the renewal of existing buildings has become imperative, and a large number of existing buildings in cities are facing the issue of functional replacement. A series of problems arising from the change of building function have become prominent, especially concerning the window and door systems of buildings with distinctive architectural styles. The challenge lies in how to maintain the existing architectural style while simultaneously meeting the requirements for lighting, waterproofing, ventilation, and energy conservation according to the desired function. Currently, both domestically and internationally, the renovation of existing buildings with distinctive architectural styles often involves the drastic replacement of window and door systems with new materials due to energy-saving requirements, resulting in the loss of historical information and damage to the architectural style.

[0003] Existing technologies often involve the drastic replacement of existing buildings with new materials. While this may meet the requirements for lighting, waterproofing, ventilation, and energy conservation in the renovated buildings, it damages the cultural heritage of the existing architecture. New door and window systems, being made of new materials, contrast sharply with the old materials used in existing buildings, creating a distinctive style that does not align with the aesthetic characteristics of renovating culturally significant existing buildings. Furthermore, the use of new materials does not conform to my country's green building development philosophy. Summary of the Invention

[0004] Based on the above analysis, the embodiments of the present invention aim to provide a window system and construction method that meet the different functional requirements of existing building renovation, so as to solve the problems of damage to the appearance of existing buildings and lack of energy conservation and environmental protection caused by the use of new materials in the process of existing building renovation.

[0005] On the one hand, the present invention provides a window system that meets the different functions of existing building renovation, including window units, the window units being disposed in window openings in existing exterior walls, the window units including a first window unit and / or a second window unit, the first window unit being used to meet the indoor lighting requirements after building renovation, and the second window unit being used to meet the indoor ventilation requirements after building renovation.

[0006] Furthermore, the first window unit includes a first existing exterior window and a first aluminum alloy glass window, wherein the first existing exterior window is located outside the first aluminum alloy glass window.

[0007] Furthermore, the second window unit includes a second existing exterior window and a second aluminum alloy glass window, with the second existing exterior window located outside the second aluminum alloy glass window.

[0008] Furthermore, the second existing exterior window does not have a window sash installed.

[0009] Furthermore, the first existing exterior window includes a wooden window frame, and the inner eaves of the wooden window frame are provided with a protective layer.

[0010] Furthermore, the first existing exterior window also includes a window sash, and the periphery of the window sash is provided with strong adhesive.

[0011] Furthermore, the first aluminum alloy glass window includes an iron base, which is fixedly connected to the existing exterior wall.

[0012] Furthermore, the first aluminum alloy glass window also includes a finished aluminum alloy window, which is mounted on the iron foot.

[0013] On the other hand, the present invention provides a construction method for a window system that meets different functional requirements under the renovation of existing buildings, the steps of which include:

[0014] Step 1: Foundation construction;

[0015] Step 2: When there is a need for natural lighting, the existing exterior wall, the first existing exterior window, and the first aluminum alloy glass window are used as a combination; when there is a need for ventilation, the existing exterior wall, the second existing exterior window, and the second aluminum alloy glass window are used as a combination.

[0016] Furthermore, when there is a need for natural lighting, the following steps are included:

Detailed Implementation

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0035] In my country, apart from historical buildings, there are a large number of existing buildings with certain cultural characteristics. These buildings resonate with the surrounding neighborhoods and should avoid being "violently" renovated using new materials. Instead, the existing building facades should be used to improve the building's life-cycle utilization rate. This will achieve the goals of lighting, waterproofing, ventilation, and thermal insulation while preserving the existing architectural style, making the buildings more green, culturally significant, and belonging to the community.

[0036] Example 1

[0037] A specific embodiment of the present invention, such as Figures 2-5 As shown, a window system is disclosed to meet different functions of existing building renovation. The system includes window units, which are installed in window openings in the existing exterior wall 1. The window units include a first window unit, a second window unit, and / or a third window unit. The first window unit is used to meet the indoor lighting requirements after the building renovation, the second window unit is used to meet the indoor ventilation requirements after the building renovation, and the third window unit is used to meet the indoor lighting requirements when there is no ventilation or lighting after the building renovation.

[0038] In this embodiment, the renovation of an existing building involves placing the first window unit, the second window unit, and / or the third window unit on the existing exterior wall. This allows the interior of the existing building to meet the needs for lighting, ventilation, and / or no ventilation and no lighting, thus fulfilling multiple functional requirements within the existing building. Furthermore, construction workers can modify the existing building according to actual needs, selectively installing the first window unit, the second window unit, and / or the third window unit on the existing exterior wall, thereby expanding the application scope of the window system.

[0039] like Figure 2 , Figure 3As shown, the first window unit includes an existing exterior window 2 and an aluminum alloy glass window 3. Both the existing exterior window 2 and the aluminum alloy glass window 3 are installed on the existing exterior wall 1, with the existing exterior window 2 located outside the aluminum alloy glass window 3. The existing exterior window 2 includes a window sash 21 and a wooden window frame 22. The existing exterior wall 1 has a window opening, and wooden blocks 20 are provided on both sides of the window opening. The wooden blocks 20 are wooden blocks retained from the existing exterior wall 1. The wooden window frame 22 is fixed to the wooden blocks 20 by wooden nails 24, and the window sash 21 is installed on the wooden window frame 22. The glass is installed on the window sash 21. The inner edge of the wooden window frame 22 has a protective layer, which is a layer of putty. The perimeter of the window sash 21 is covered with strong adhesive, and the outer side of the window sash 21 is provided with nails, with at least two nails on each frame edge, so that the window sash 21 and the wooden window frame 22 are firmly installed.

[0040] In this embodiment, the window sash 21 is fixedly connected to the wooden window frame 22 by bonding and nailing, which avoids the large damage caused by the installation method of setting grooves on the wooden window frame 22 and ensures the relative integrity of the existing wooden window frame 22.

[0041] like Figure 3 As shown, the aluminum alloy glass window 3 includes an iron base 30 and an aluminum alloy finished window 31. The iron base 30 is fixed to the existing exterior wall 1 by plastic expansion bolts. The aluminum alloy finished window 31 is installed on the iron base 30. Foam material is filled between the aluminum alloy finished window 31 and the existing exterior wall 1, and the connection between the two is sealed with sealant.

[0042] In order to reduce thermal bridges and improve thermal insulation performance, a second insulation board 42 is provided between the existing exterior window 2 and the aluminum alloy finished window 31. The second insulation board 42 is fixed to the inside of the window opening of the existing exterior wall 1 with adhesive. Preferably, the thickness of the second insulation board 42 is 30mm.

[0043] In this embodiment, a first insulation board 14 is provided on the inner side of the existing outer window 2 as a base plate for the aluminum alloy finished window 31, which reduces the cold bridge of the window, improves the insulation performance, and increases the energy saving.

[0044] like Figure 2 , Figure 5 As shown, the second window unit differs from the first window unit in that the second window unit does not include the window sash 21, that is, the window sash 21 is not placed inside the wooden window frame 22. Other structures and beneficial effects are the same as the first window unit, and will not be described in detail here.

[0045] like Figure 2 , Figure 4As shown, the third window unit differs from the first window unit in that it uses an integrated insulation panel 4 to replace the prefabricated aluminum alloy window 31, resulting in a change in the installation structure. Other structural features and beneficial effects are the same as the first window unit and will not be elaborated upon here. The differences between the third and first window units are explained below:

[0046] like Figure 4 As shown, the third window unit also includes an integrated insulation board 4, which is located inside the existing exterior window 2. A second insulation board 42 is provided between the integrated insulation board 4 and the existing exterior window 2. The integrated insulation board 4 is located within a rigid steel frame.

[0047] The rigid steel frame is formed by a first angle steel 40 and a second angle steel 41. The two side plates of the first angle steel 40 are respectively attached to the inner side of the existing exterior wall 1 and the side of the window opening. The second angle steel 41 is stacked on top of the first angle steel 40 and fixed with No. 10 expansion bolts 12, and connected to the existing exterior wall 1. Adjacent No. 10 expansion bolts 12 are spaced 600mm apart. One side plate of the first angle steel 40 and one side plate of the second angle steel 41 are attached parallel to each other, and the other side plate of the first angle steel 40 and the other side plate of the second angle steel 41 are collinear. The sum of the lengths of the collinear side plates of the first angle steel 40 and the second angle steel 41 is greater than the thickness of the integrated insulation board 4 to ensure a stable placement space for the integrated insulation board 4.

[0048] The integrated insulation board 4 includes a third insulation board 43 and a second calcium silicate board 44. The second calcium silicate board 44 is provided on both sides of the third insulation board 43. The existing building style logo is affixed to the second calcium silicate board 44 facing the outside.

[0049] The integrated insulation board 4 in this embodiment is an independent 100mm thick insulation board with calcium silicate boards on both sides. It is connected to the internal insulation board system at the top and bottom and fixed with the upper and lower steel frames and the local insulation system on both sides. It is combined with the existing exterior wall to form an upgraded version of the existing exterior wall that can replace the internal insulation board system. The exterior side of the integrated insulation board is affixed with the existing building style logo, which further improves the continuity of the existing building style.

[0050] To fix the finished aluminum alloy window 31 and the integrated thermal insulation board 4, a first calcium silicate board 17 is provided on the inner side of the existing exterior wall 1. The first calcium silicate board 17 is fixed to the keel support 13 by cement nails 18, and the keel support 13 is fixed to the existing exterior wall 1 by 10th expansion bolts 12. Here, the 10th expansion bolts 12 are spaced 350 mm vertically and 600 mm horizontally along the existing exterior wall 1. A first thermal insulation board 14 is provided between the existing exterior wall 1 and the first calcium silicate board 17. The first thermal insulation board 14 is fixed to the inner side surface of the existing exterior wall 1 by a thermal insulation board adhesive, and the first thermal insulation board 14 is in frictional contact with the 10th expansion bolts 12 to improve the stability of the connection of the first thermal insulation board 14. A wire mesh 15 is provided on the inner side of the first thermal insulation board 14, and the wire mesh 15 is fixed to the first thermal insulation board 14 by matching thermal insulation nails, and the interior wall latex paint 16 is applied externally.

[0051] The first calcium silicate board 17 is in a "U" shape, and a first thermal insulation board 14 is arranged in the space between it and the existing exterior wall 1. The distance between the corner board of the first calcium silicate board 17 and the second thermal insulation board 42 is equal to the thickness of the finished aluminum alloy window 31 or the integrated thermal insulation board 4.

[0052] In this embodiment, setting the first calcium silicate board 17 in a "U" shape not only provides a placement space for the first thermal insulation board 14 and the wire mesh 15, but also forms a placement space for the finished aluminum alloy window 31 or the integrated thermal insulation board 4 in combination with the second thermal insulation board 42, making the placement of the first thermal insulation board 14, the first calcium silicate board 17, the second thermal insulation board 42, the finished aluminum alloy window 31 and the integrated thermal insulation board 4 compact, and improving the space utilization rate.

[0061] Step 1.5: Re-roughen the inner surface of the existing exterior wall 1, and reserve No. 10 expansion bolts 12 at vertical intervals of 350mm and horizontal intervals of 600mm to fix the keel support component 13 of the calcium silicate board of the exterior decoration material.

[0062] Step 1.6: Apply the insulation board adhesive to the inner side of the first insulation board 14 and fix it to the existing exterior wall 1. At the same time, make friction contact with the reserved No. 10 expansion bolts 12 to improve stability.

[0063] Step 1.7: Use matching insulation nails to fix the wire mesh 15 onto the first insulation board 14, and then apply interior wall latex paint 16 to the outside.

[0064] Step 1.8: Hang the first calcium silicate board 17 on the keel support 13 and fix it with cement nails 18.

[0065] Step 2: When there is a need for natural lighting, the existing exterior wall 1, the existing exterior window 2, and the aluminum alloy glass window 3 are combined to achieve this, and step 2.1 is executed; when there is a need for ventilation, the existing exterior wall 1, the existing exterior window 2 (excluding window sash 21), and the aluminum alloy glass window 3 are combined to achieve this, and step 2.2 is executed; when there is no need for natural lighting or ventilation, the existing exterior wall 1, the existing exterior window 2, and the integrated insulation board 4 are combined to achieve this, and step 2.3 is executed.

[0066] Step 2.1: The renovation will utilize existing exterior walls 1, existing exterior windows 2, and aluminum alloy glass windows 3 to meet the lighting requirements. The construction steps include:

[0067] Step 2.1.1: Install the existing exterior window 2, and use special wooden nails 24 to fix the repaired wooden window frame 22 to the retained wooden bricks 20 of the existing exterior wall 1.

[0068] Step 2.1.2: After the existing exterior window 2 is secured, install the glass window sash 21.

[0069] To ensure the integrity of the existing wooden window frame 22 and avoid using a grooved installation method that would damage the wooden window frame 22, the window sash 21 is fixed by adhesive and nailing.

[0070] The specific steps include:

[0071] Step 2.1.2.1: Cut the glass according to the existing wooden window frame 22 for later use.

[0072] Step 2.1.2.2: Apply a layer of putty to the inner edge of the wooden window frame 22 to protect it.

[0084] Step 2.2.2: Fix a 30mm thick second insulation board 42 to the inside of the window opening with adhesive to serve as the inner module base plate, reduce cold bridges, improve insulation performance, and increase energy efficiency.

[0085] Step 2.2.3: Install the finished aluminum alloy window 31.

[0086] Since the existing exterior wall 1 does not have any embedded iron parts, the following construction steps will be adopted:

[0087] Step 2.2.3.1: Fix the iron foot 30 to the existing exterior wall 1 using plastic expansion bolts.

[0088] Step 2.2.3.2: Install the finished aluminum alloy window 31 into the iron foot 30. To facilitate the replacement of the finished aluminum alloy window 31, the outer frame of the finished aluminum alloy window 31 is detachably connected to the window opening.

[0089] Step 2.2.3.3: Fill the gap between the outer frame of the finished aluminum alloy window 31 and the existing exterior wall 1 with foam material in layers, and then seal the joint with sealant.

[0090] Step 2.2.3.4: Conduct a spray test on the installed windows to check their sealing performance.

[0091] Step 2.3: The existing exterior wall 1, existing exterior windows 2, and integrated insulation board 4 are combined in a construction process to achieve a renovation without the need for natural light or ventilation. The construction steps include:

[0092] Step 2.3.1: Install the existing exterior window 2, and use special wooden nails 24 to fix the repaired wooden window frame 22 to the retained wooden bricks 20 of the existing exterior wall 1.

[0093] Step 2.3.2: After the existing exterior window 2 is secured, install the glass window sash 21.

[0094] To ensure the integrity of the existing wooden window frame 22 and avoid using a grooved installation method that would damage the wooden window frame 22, the window sash 21 is fixed by adhesive and nailing.

[0095] The specific steps include:

[0096] Step 2.3.2.1: Cut the glass according to the existing wooden window frame 22 for later use.

[0097] Step 2.3.2.2: Apply a layer of putty to the inner edge of the wooden window frame 22 to protect it.

[0098] Step 2.3.2.3: Apply strong adhesive to the perimeter of the glass window sash 21, and place the glass window sash 21 with strong adhesive inside the opening of the wooden window frame 22 and press lightly to bond the perimeter of the glass to the base putty.

[0099] Step 2.3.2.4: Fix small nails along the outside of the glass window sash 21 at 300mm intervals, with at least 2 nails on each frame edge; the nailing sequence is: top edge of wooden window frame 22, bottom edge of wooden window frame 22, and both sides of wooden window frame 22.

[0100] Step 2.3.3: Fix a 30mm thick second insulation board 42 to the inside of the window opening with adhesive to serve as the inner module base plate, reduce cold bridges, improve insulation performance, and increase energy efficiency.

[0101] Step 2.3.4: Reserve No. 10 expansion bolts 12 every 600mm around the window opening, and nail at least 2 bolts at each window opening edge; stack 50mm thick first angle steel 40 and 100mm thick second angle steel 41 and fix them with the reserved No. 10 expansion bolts 12 to form a rigid steel frame at the window opening.

[0102] Note that the sum of the lengths of the first angle steel 40 and the second angle steel 41 should be greater than the thickness of the integrated insulation board 4.

[0103] Step 2.3.5: Install the integrated insulation board 4.

[0104] Apply strong adhesive to all four sides of the integrated insulation board 4, insert it into the rigid steel frame formed in step 4, and fix the integrated insulation board 4. One side is based on the 30mm thick second insulation board 42, and the other side is secured by the corner plate of the existing calcium silicate board 17 in the exterior wall 1.

[0105] In this embodiment, the first calcium silicate board 17, shaped like the letter "U", provides space for the first insulation board 14 and the wire mesh 15. At the same time, the corner plate of the first calcium silicate board 17, combined with the second insulation board 42, forms a space for the aluminum alloy finished window 31 or the integrated insulation board 4. This makes the first insulation board 14, the first calcium silicate board 17, the second insulation board 42, the aluminum alloy finished window 31, and the integrated insulation board 4 compactly arranged, thus improving space utilization.

[0106] The integrated insulation board 4 is composed of a 100mm thick third insulation board 43 and two second calcium silicate boards 44 on both sides. The second calcium silicate board 44 on the indoor side is the same as the first calcium silicate board 17 in the existing exterior wall 1 system. The second calcium silicate board 44 on the outdoor side is affixed with the existing building style logo.

[0107] In this embodiment, the integrated insulation board 4 is combined with the existing exterior wall to form an upgraded version of the existing exterior wall that can replace the internal insulation board system. The exterior side of the integrated insulation board is affixed with the existing building style logo, which further enhances the continuity of the existing building style.

[0108] The window system provided in this embodiment satisfies the requirements of lighting, waterproofing, ventilation, and thermal insulation and energy saving in the renovated building. It is particularly evident in the renovation of existing buildings with distinctive architectural features, protecting the building's existing cultural context and spirit, and enhancing the sense of belonging for subsequent users and surrounding residents. At the same time, the rational use of the exterior windows of existing buildings improves the utilization rate of materials throughout the building's life cycle, saves resources, and achieves the efficiency of existing green buildings.

[0109] The window system provided in this embodiment, based on the needs of indoor functional space replacement, considers combining existing exterior walls, existing windows with glass, and aluminum-plastic glass windows when lighting is required, ensuring that the existing building appearance remains unchanged on the outside; when ventilation is required, consider combining existing exterior walls, existing windows without glass, and aluminum-plastic glass windows to reduce manual operation and increase ventilation efficiency; when lighting and ventilation requirements are not high, consider combining existing exterior walls, existing windows with glass, and integrated insulation panels to save energy and maintain the building appearance while keeping it warm.

[0110] The window system provided in this embodiment overcomes the incongruity of new materials with the appearance of existing buildings, improves the utilization rate of existing buildings throughout their entire life cycle, and has strong potential for promotion in a large number of general existing buildings with certain cultural characteristics in Chinese cities.
