Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to a method for installing a passive building insulation strip, an insulation strip installation node, and a door and window node. Background Art

[0002] As the world pays more and more attention to energy conservation, emission reduction and sustainable development, passive buildings have achieved extremely low heating and cooling energy consumption through their efficient building envelope and indoor environment design, and have received extensive attention and promotion. As an important part of the building envelope system, the thermal insulation performance of doors and windows is directly related to the energy-saving effect of the building. Therefore, the application of door and window insulation technology is particularly important in passive buildings.

[0003] As the key material between the door and window frames and the wall, the insulation strip forms a tight sealing connection between the door and window frames and the wall, effectively preventing indoor and outdoor air convection, heat transfer and rainwater leakage, and improving the air tightness of doors and windows. When installing the insulation strip, it is usually embedded in the gap between the door and window frames and the wall by pasting, snapping, etc., but this method is not firmly fixed, and it is easy to deviate or break during the concrete pouring process, and the molding effect is poor, which in a sense loses the role that the insulation strip should play. Some methods also use steel bars to pass through the insulation strips to fix them on the insulation board, or use wire tying to fix them, but similar methods cannot effectively fix them. At present, there is no systematic and clear installation and fixing method for the insulation strips of passive building doors and windows. The existing methods are also difficult to ensure the molding quality. Whether it is pasting, snapping, or anchoring through the insulation board, tying wires, etc., the insulation strips are fixed to the insulation board, but the insulation board itself is a flexible material and it is difficult to form a rigid connection with the insulation strip. During the pouring process, under the impact load of pouring and the force of vibration, it is easy to deviate or break, and it may even damage or deform the insulation board. It cannot meet the requirements of passive buildings for the air tightness, thermal insulation and other performance of doors and windows, and measures such as snapping and tying wires are costly, difficult to construct, time-consuming and labor-intensive, and the construction is complicated, labor-intensive and material-intensive.

[0039] like Figure 1 , Figure 4 as well as Figure 6 As shown, the present invention discloses a method for installing a passive building insulation strip, which is used to install an insulation strip 20 on a wall structure 10 of a passive building. The method includes: S1 to S3.

[0040] S1. Fix the insulation strip on the inner side of the wooden formwork to form a first formwork.

[0041] The insulation strip 20 is fixed on the inner side of the wood formwork 30 to form the first formwork. Specifically, the insulation strip 20 can be a longitudinal autoclaved sand aerated concrete block, which has the characteristics of fire retardancy, heat insulation, sound absorption and sound insulation, waterproof and anti-seepage, safety and durability. The insulation strip 20 is a key material between the door and window frame 50 and the wall, and forms a tight sealing connection between the door and window frame 50 and the wall, effectively preventing indoor and outdoor air convection, heat transfer and rainwater leakage, and improving the air tightness of the door and window. The wood formwork 30 can be made of plywood. The inner side of the wood formwork 30 is the side that contacts the concrete when pouring concrete, and the side opposite to the inner side of the wood formwork 30 is the outer side of the wood formwork 30. The insulation strip 20 is fixed on the inner side of the wood formwork 30, and one side of the insulation strip 20 is tightly fitted with the inner side of the formwork, so that the insulation strip 20 can contact and cooperate with the wall structure 10 of the passive building.

[0042] S2. Installing a wall formwork, wherein the wall formwork includes the first formwork.

[0043] The wall formwork is supported, wherein the wall formwork includes the first formwork. Specifically, the wall in this embodiment is an exterior wall in a passive building, and the doors and windows of the passive building are generally arranged on the exterior wall. The wall formwork may include a first formwork with a smaller area and a second formwork with a larger area. The first formwork is a formwork whose width matches the thickness of the wall, and the second formwork is a formwork whose length and height match the length and height of the wall. The formworks can be connected by connecting parts such as bolts and locating pins, and the wall formwork as a whole can be fixed in position by supporting parts such as scaffolding, so that the overall strength and stability of the formwork are relatively high. Fixing the insulation strip 20 on the formwork can effectively prevent the insulation strip 20 from being offset or broken during the wall pouring and vibration process, and relative to fixing the insulation strip 20 on the insulation board, there is no need to drill anchor holes on the insulation board, which can avoid damage or deformation of the insulation board.

[0044] S3. Concrete is poured inside the wall formwork to form a wall structure, and the thermal insulation strip is fixedly installed on the wall structure by the bonding force of the concrete.

[0045] Concrete is poured on the inner side of the wall formwork to form a wall structure 10, and the insulation strip 20 is fixedly installed on the wall structure 10 by the bonding force of the concrete. Specifically, on the inner side of the wall formwork, i.e., on the side with the insulation strip 20, when concrete is poured, the concrete wraps around the sides of the insulation strip 20 that are not in contact with the wooden formwork 30, so that after the concrete solidifies and hardens, the insulation strip 20 and the wall structure 10 are tightly fixed together, which can effectively improve the airtightness between the insulation strip 20 and the wall structure 10, thereby improving the thermal insulation performance of the passive building. Moreover, during the whole process, in addition to the bonding force provided by the concrete, the insulation strip 20 and the insulation board are not connected by steel bars, binding wires or clips. On the one hand, this avoids the loss of structural performance of the already flexible insulation board, such as drilling anchor holes. On the other hand, compared with fixing the insulation strip to the flexible insulation board, the formwork system with greater overall stability and strength (i.e., the system composed of the wooden formwork 30 and various connecting parts and supporting parts) can provide better support and rigid connection for the insulation strip 20. During the pouring and vibrating of concrete, the position of the insulation strip 20 will not shift.

[0046] In some embodiments, before the insulation strip 20 is fixed to the wooden formwork 30 to form the first formwork, the steps include:

[0047] Erection and tying of wall reinforcement;

[0048] Place the wall insulation board 12.

[0049] Install and tie the wall reinforcement; place the wall insulation board 12, specifically, as Figure 3 As shown, the wall structure 10 may include a base wall 11, a wall insulation board 12 and a protective layer 13. It should be noted that: Figure 3 The base wall 11 and the protective layer 13 in the figure only illustrate their positional relationship. In fact, at this step, the specific structure of the base wall 11 and the protective layer 13 has not yet been formed. As the main structure of the passive building, the base wall 11 plays the main load-bearing and enclosure role. This part of the wall has high strength requirements, and it is necessary to erect and tie the steel bars before the formwork is supported. The wall insulation board 12 can be a graphite polystyrene board, which has excellent thermal insulation and flame retardant properties, and is used to improve the overall thermal insulation performance of the wall structure 10. The protective layer 13 is arranged on the outside of the wall insulation board 12, that is, the wall insulation board 12 is arranged between the base wall 11 and the protective layer 13. The protective layer 13 is mainly used to prevent the base wall 11 and the wall insulation board 12 from being eroded. This part of the wall does not need to be reinforced, and concrete can be poured after the wall formwork is erected.

[0050] In some embodiments, Figure 2 and Figure 4As shown, the method of fixing the insulation strip 20 on the inner side of the wooden template 30 to form a first template includes:

[0051] S11, calculating the corresponding positions of the wooden formwork and the wall insulation board;

[0052] S12, marking the position of the wooden formwork corresponding to the wall insulation board to determine the fixing area of ​​the insulation strip;

[0053] S13, fixing the thermal insulation strip on the wooden formwork by means of fixing parts.

[0054] In this embodiment, in order to avoid the position of the insulation strip 20 being inconsistent with the expected position after the first template is erected, the position area corresponding to the wall insulation board 12 on the wooden template 30 is first calculated, and lines are drawn in the position area. Two parallel lines can be drawn on the wooden template 30, and the distance between the two parallel lines matches the width of the insulation strip 20. That is, the area between the two parallel lines is the fixed area of ​​the insulation strip 20. Specifically, when performing the calculation, the distance from the two side edges of the wall insulation board 12 to the second template on both sides of the wall can be calculated, and the middle area where the distance from the outer edges of the two sides of the corresponding first template to the middle is equal to the distance from the two side edges of the insulation board to the second template on both sides of the wall is determined as the position area corresponding to the wall insulation board 12, and parallel lines equal to the width of the insulation strip 20 are drawn in this area, that is, the width of the insulation strip 20 is less than the thickness of the wall insulation board 12. After determining the fixing area of ​​the insulation strip 20, the insulation strip 20 is placed tightly against the fixing area of ​​the insulation strip 20, and the insulation strip 20 is fixed to the wood formwork 30 by the fixing member 40. It should be noted that the "fixing" mentioned here means that when the fixing member 40 plays a fixing role, the insulation strip 20 will not move relative to the wood formwork 30, and does not mean that the connection between the wood formwork 30 and the insulation strip 20 will never be released. Figure 4 The base wall 11 and the protective layer 13 in the figure are only used to illustrate their positional relationship. In fact, at this step, the specific structures of the base wall 11 and the protective layer 13 have not yet been formed.

[0055] In some embodiments, the fixing member 40 is at least one of a self-tapping screw and a nail.

[0056] The fixing member 40 is at least one of a self-tapping screw and a nail, that is, the fixing member 40 can be entirely made of self-tapping screws or entirely made of nails, or a combination of self-tapping screws and nails. Self-tapping screws and nails can not only play a fixing role, but also are simple to construct, which can save labor and material costs.

[0057] In some embodiments, marking the position of the wooden template 30 corresponding to the wall insulation board 12 to determine the fixing area of ​​the insulation strip 20 includes:

[0058] Lines are drawn on the inner and outer sides of the wooden template 30; wherein the area formed by the lines on the inner side of the wooden template 30 is the fixing area of ​​the insulation strip 20, and the area formed by the lines on the outer side of the wooden template 30 is the nailing area of ​​the fixing part 40.

[0059] Specifically, when marking the positions corresponding to the wood formwork 30 and the wall insulation board 12 to determine the fixing area of ​​the insulation strip 20, marking is performed on the inner and outer sides of the wood formwork 30. The area formed by the marking on the inner side of the wood formwork 30 is the fixing area of ​​the insulation strip 20, and the area formed by the marking on the outer side of the wood formwork 30 is the nailing area of ​​the fixing member 40. That is, the fixing area of ​​the insulation strip 20 and the nailing area of ​​the fixing member 40 are not only equal in area, but also correspond to each other on the inner and outer sides of the wood formwork 30, thereby ensuring that the self-tapping screw or iron nail can be accurately nailed into the insulation strip 20 set on the inner side of the wood formwork 30 when nailing from the wood formwork 30 to the inner side of the wood formwork 30, and the relative position of the self-tapping screw or iron nail in the nailing area is the relative position of the self-tapping screw or iron nail on the insulation strip 20, thereby ensuring that the fixing member 40 can fix the insulation strip 20 at an accurate position and facilitate construction.

[0060] In some embodiments, along the length direction of the heat preservation strip 20, a fixing member 40 is arranged at intervals of 10 to 20 cm.

[0061] In this embodiment, taking the fixing member 40 as an iron nail as an example, along the length direction of the insulation strip 20, that is, along the length direction of the above-mentioned nailing area, an iron nail is arranged every 10 to 20 cm, that is, a row of iron nails is arranged, and the specific interval can be 10cm, 12cm, 14cm, 15cm, 16cm, 18cm or 20cm. The interval between each two adjacent iron nails can be kept equal or unequal. For example, iron nails should be arranged at both ends of the nailing area as much as possible, that is, the interval between the iron nails closest to the two ends and the adjacent iron nails is not equal to the interval between the other two iron nails.

[0062] In some other embodiments, the fixing members 40 may also be arranged in two rows, that is, two iron nails are arranged at a certain interval along the length direction of the nailing area.

[0063] In some embodiments, the tip of the fixing member 40 is nailed from the outside of the wooden formwork 30 to the inside of the wooden formwork 30 , and the tip of the fixing member 40 is immersed in the insulation strip 20 to fix the insulation strip 20 on the wooden formwork 30 .

[0064] Taking the fixing member 40 as an iron nail, for example, an iron nail with a length of 7 cm can be selected, and the tip of the iron nail is nailed from the nailing area on the outside of the wood template 30 to the inside of the wood template 30, and the tip of the fixing member 40 is immersed in the insulation strip 20 that fits in the fixing area of ​​the insulation strip 20, so as to fix the insulation strip 20 on the wood template 30. In addition, the length of the iron nail should be less than the sum of the thickness of the template and the insulation strip 20, that is, the iron nail only fixes the wood template 30 and the insulation strip 20, and will not form a nail hole in the wall insulation board, thereby avoiding structural damage to the flexible wall insulation board 12, thereby ensuring the insulation performance of the wall structure 10 in the passive building.

[0065] In some embodiments, Figure 5 As shown, after pouring concrete inside the wall formwork to form a wall structure 10, and fixing the insulation strip 20 on the wall structure 10 by the bonding force of the concrete, the following steps are included:

[0066] After the concrete of the wall structure 10 reaches the designed strength, the formwork and the fixing member 40 are removed.

[0067] In this embodiment, when the concrete of the base wall 11 and the protective layer 13 in the wall structure 10 reach the designed strength, when the formwork is removed, the fixing parts 40 nailed to the first formwork are also removed, thereby obtaining the completed insulation strip 20 and wall structure 10, and the insulation strip 20 is firmly fixed to the wall structure 10 through the bonding force of the concrete.

[0068] The present invention also discloses a passive building door and window insulation strip 20 installation node, see Figure 5 The installation node is obtained through the passive building insulation strip 20 installation method disclosed in the embodiment, and the installation node includes the wall structure 10 and the insulation strip 20 fixedly installed on the wall structure 10. The wall structure 10 includes a base wall 11, a wall insulation board 12 and a protective layer 13.

[0069] Among them, the protective layer 13 is closer to the outdoors, and the base wall 11 is closer to the indoors.

[0070] The present invention also discloses a passive building door and window node, see Figure 6 The passive building door and window node includes a door and window frame 50 and an installation node of the passive building door and window insulation strip 20 disclosed in the above embodiment. The door and window frame 50 is tightly connected to the wall structure 10 and the insulation strip 20.

[0071] Specifically, the passive building door and window node also includes door and window glass arranged on the inner side of the door and window frame 50. The door and window glass is usually made of composite glass that is vacuum or filled with inert gas (such as argon). Through meticulous construction and sealing treatment, a complete sealing system is formed between the door and window frame 50 and the wall structure 10 of the exterior wall; the insulation strip 20 is located in the gap between the door and window frame 50 and the wall structure 10, so that a tight sealing connection is formed between the door and window frame 50 and the wall.

[0072] The present invention has at least the following beneficial effects:

[0073] The invention discloses a method for installing a passive building insulation strip. The method fixes the insulation strip 20 and the wooden formwork 30 with iron nails or self-tapping screws. There is no need to apply glue, punch holes, tie wires or reserve buckles on the insulation board, and there is no need to install in advance. The method has simple procedures, simple installation and disassembly, saves manpower and material costs, and effectively avoids the insulation strip 20 from being offset or broken during concrete pouring, ensures the sealing between the door and window frame 50 and the wall, solves the problems of offset, breakage, poor molding quality of the passive building door and window insulation strip 20 during pouring, and avoids the air tightness, thermal insulation and other properties of the passive building due to offset, breakage and other problems after pouring and molding. The method is simple to construct and reliable to use, reduces additional construction content, simplifies the construction procedure, and does not require too much material and manpower. Compared with the traditional method for fixing the insulation strip 20, the method is low in cost, fast and efficient, reduces the construction procedure, saves a lot of labor and material resources, saves engineering construction costs, and has significant economic benefits. At the same time, the level of passive building door and window construction technology is improved.

[0074] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
