Description

Technical Field

[0001] The present invention relates to the technical field of high-performance thermal insulation window construction, and particularly to a method for installing extra-long multi-panel windows. Background Art

[0002] External wall doors and windows are important components of building projects, the facade symbols of buildings, and at the same time important parts of people's production and living environments. Especially for hospital buildings, functions such as daylighting and ventilation of windows are particularly important. Existing hospitals usually have horizontal through-windows on each floor, and multiple window frames need to be installed to meet the design requirements. However, during the on-site installation process, there are usually the following difficulties:

[0003] 1) When the size of the external window opening is too large and involves the installation of multiple windows, the construction is relatively difficult, and it is not easy to control the horizontality and verticality of the windows.

[0004] 2) The window frame is fixed by connecting with the upper and lower concrete structures through expansion bolts, and there is no connection in the horizontal direction. The construction quality of the installation directly affects the use safety.

[0005] 3) Since the window sill coping is too long, if the leveling quality of the upper surface does not meet the requirements, secondary chiseling and leveling are required, which is time-consuming and laborious, increases costs, and the gap size deviation between the window frame and the window sill is uneven, making it easy to have potential leakage problems.

[0006] 4) It is difficult to control the gap at the connection between the end of the opening and the wall, and it is easy to have a situation where it is greater than 2 cm. This part is also prone to potential leakage problems.

[0007] Based on the above problems, the traditional window frame installation method is now improved and optimized. Summary of the Invention

[0008] The embodiment of the present invention provides a method for installing extra-long multi-panel windows, which can better control the horizontality and verticality of large-sized through-windows, form the window sill in one time, without the need for secondary treatment, and avoid water seepage.

[0009] On one hand, the present invention provides a method for installing extra-long multi-panel windows, which is carried out according to the following steps:

[0010] S1. Determine the elevation controlling the upper and lower parts of the window frame on the wall;

[0011] S2. Confirm the opening size: Check the size deviation of the bottom of the structural beam at the top of the window frame. When the flatness of the bottom of the beam is greater than the specification requirements, chisel the bottom of the top beam; confirm the elevation of the top of the window sill coping at the bottom of the window frame, and carry out concrete leveling according to the confirmed elevation to ensure that the window frame can be accurately installed into the opening after subsequent processing.

[0012] S3. Pour the window sill coping: Pour concrete according to the design of the window sill coping;

[0013] S4. Pull-out test: Before installing the window frame, a pull-out test is performed on the expansion bolts used for window frame installation to ensure that the expansion bolts meet the design strength requirements;

[0014] S5. Window frame line: Place the window frame line on the top cap based on the inner window frame line;

[0015] S6. Window frame installation: Install the window frame starting from the end against the wall, as follows:

[0016] Frame erection: Place the single window frame in the opening, following the window frame line;

[0017] Airbag leveling: insert airbags into the gap between the upper and lower frames and the structure. Select the number of airbags to be placed according to the length of the window frame. Use the airbags to adjust the horizontal and vertical degree of the window frame.

[0018] Place shims: After the level adjustment is completed, place shims at the bottom of the window frame;

[0019] Verticality and flatness detection: Use a ruler to check the verticality and flatness of the window frame;

[0020] Expansion bolt fixing: After the verticality and flatness meet the requirements, use expansion bolts to fix the window frame to the wall. Expansion bolts are prohibited to be installed at the window sash position.

[0021] S7, horizontal connection of window frames: Repeat step S6 to install the remaining window frames, and use whole strips to connect adjacent window frames, and use high-strength screws to connect adjacent horizontal window frames;

[0022] S8. Treatment of joints at the connection with the wall: Use fine stone concrete to seal the edges of areas where leakage is likely to occur between the window frame and the wall. Use fine stone concrete to fill any gaps between the window frame and the wall that are too large.

[0023] S9. Caulk the seams with foaming agent: Use foaming agent to caulk the seams after the window frame is installed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The window sill of the present invention is formed in one step, which reduces the cost of secondary chiseling treatment, simplifies the window sill forming process, and speeds up construction efficiency; the use of airbag leveling solves the problem of difficult control of verticality and horizontality of large-size through-window frames; adjacent horizontal window frames are connected to improve the safety of the window frames; and node treatment is performed after the window frames are installed to solve the problem of water leakage in the window frames.

[0026] Furthermore, the preferred embodiment of the present invention is:

[0027] In step S3, determine the height difference between the outer edge line of the window frame and the elevation of the coping outer skin according to the slope i to ensure that the slope i meets the design requirements after the cement mortar leveling.

[0028] In step S7, the high-strength screws used for fixing two adjacent horizontal window frames are arranged staggeredly, and the spacing is less than or equal to 300m. Description of the Drawings

Detailed Embodiment

[0037] To make the purpose, technical solution, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the embodiments and the drawings. Herein, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but do not limit the present invention.

[0038] A method for installing an extra-long multi-panel window is carried out according to the following steps:

[0039] S1. Lay a horizontal 1m line on the wall 4 to control the elevation of the upper and lower parts of the window frame 5.

[0040] S2. Confirm the opening size: As Figure 1As shown in the figure, first, check the dimensional deviation of the bottom of the structural beam 1 at the top of the window frame 5. Since the opening 2 of the window is too long, before the production of the window frame 5, refer to the 1m line to verify the horizontal deviation of the bottom of the beam. When the flatness of the bottom of the beam is greater than the specification requirements, chisel the top of the beam to ensure that the gap between the upper opening of the window frame 5 and the structural beam 1 is within the allowable range. Secondly, confirm the top elevation of the window sill coping 3 at the bottom of the window frame 5, and carry out concrete leveling according to the confirmed elevation to avoid waviness, ensuring that the window frame 5 can be accurately installed into the opening 2 after subsequent processing is completed, and ensuring that the gap between the bottom of the window frame 4 and the coping 3 meets the requirements.

[0041] S3. Pouring the window sill coping: As Figure 2 shown, carry out concrete pouring according to the design of the window sill coping. The coping 3 should ensure both its levelness and that the exterior construction window sill slopes outward to avoid water seepage. Determine the height difference between the outer edge line 51 of the window frame and the elevation of the outer skin of the coping 6 according to the slope i, ensuring that the slope i meets the design requirements after the cement mortar 14 is leveled to avoid water seepage at the bottom of the window sill.

[0042] S4. Pull-out test: Since the window is composed of multiple window frames 5 spliced together, and the vertical frames of the window frame 5 are not fixed to the structural wall, before installing the window frame 5, conduct a pull-out test on the expansion bolts 7 used for installing the window frame 5 to ensure that the expansion bolts 7 meet the strength requirements of the design and avoid potential safety hazards for the window.

[0043] S5. Laying out the window frame line: Use the inner edge line of the window frame 5 as the standard to lay out the window frame line on the coping 3; [[ID=I3]]

[0044] S6. Installing the window frame: Start installing the window frame 5 from the end against the wall. As Figure 3 shown, the details are as follows:

[0045] Setting up the frame: Place the single-window frame 5 in the opening 2 and place it according to the window frame line;

[0046] Leveling with airbags: Insert the airbags 15 into the gaps between the upper and lower frames and the structure. Select the number of airbags 15 to be placed according to the length of the window frame 5, and adjust the levelness and perpendicularity of the window frame 5 through the airbags 15;

[0047] Placing gaskets: After the levelness adjustment is completed, place the gaskets 9 at the bottom of the window frame 5;

[0048] Checking vertical and horizontal flatness: Use a straightedge to check the perpendicularity and levelness of the window frame;

[0049] Fixing with expansion bolts: After the perpendicularity and levelness meet the requirements respectively, use the expansion bolts 7 to fix the window frame 5 to the wall 4. The spacing of the expansion bolts 7 meets the requirements of the design specifications, and expansion bolts 7 are prohibited from being installed at the position of the window sash 8 to avoid water seepage points.

[0050] S7. Transverse connection of the window frame: As Figure 4, 5 As shown, repeat step S6 to install the remaining window frames, and use the whole splicing strip 11 to connect adjacent window frames. Use high-strength screws 10 to connect between adjacent horizontal window frames, and the high-strength screws 10 are arranged staggeredly with a spacing less than or equal to 300 mm.

[0051] S8. Node treatment at the connection part with the wall: As Figure 6 shown, for the parts where the window frame 5 and the wall 4 are prone to leakage, use fine aggregate concrete 12 to seal the edges. For the positions with too large gaps between the window frame 5 and the wall 4, use fine aggregate concrete 12 to fill and compact.

[0052] S9. Foaming agent caulking: After the installation of the window frame 5 is completed, use the foaming agent 13 for caulking.

[0053] The present invention solves the problem that it is not easy to control the verticality and flatness of the large-size through-window frames. The window sill is formed in one time, reducing the cost of secondary chiseling, simplifying the window sill forming process, accelerating the installation speed, making the window frame installation more firm, avoiding potential safety hazards, and at the same time solving the common quality problem of easy water seepage of the window frame.

[0054] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
