Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a window frame installation method. Background Art

[0002] With the rapid development of social economy, people's requirements for building lighting have increased dramatically. In order to meet this demand, windows are often added to the wall to increase lighting. The window frame is the connection between the window and the wall, and its sealing is very important. During the construction process, a window hole for installing the window frame will be reserved on the wall. In order to facilitate installation, the size of the window hole will be slightly larger than the size of the door frame for easy installation, which will leave a gap between the door frame and the window hole. Therefore, the gap will be sealed after the installation is completed.

[0003] Usually, the edge of the window frame is shown in the Chinese utility model patent with the authorization announcement date of March 22, 2024 and the authorization announcement number of CN220644666U. The edge of the window frame combined with the wall is not a flat plane. In order to facilitate the close combination of the window frame and the wall, the cross-section of the edge of the window frame for contacting the wall is U-shaped, and the opening of the U-shape faces the wall. For the sealing between the window frame and the wall. Generally speaking, there are two methods. One is to inject foam sealant through the gap between the window frame and the wall after placing the window frame in the window hole of the wall. The foam sealant will expand between the window frame and the wall and gradually fill it completely. Another method is to inject mortar between the window frame and the wall. For example, the Chinese invention patent application with the application publication date of January 20, 2016 and the application publication number of CN105257149A discloses a method for sealing the gap of aluminum alloy doors and windows in coastal areas. The sealing method installs the window frame in the window hole, makes mortar, and fills the mortar into the gap between the window frame and the wall to complete the installation of the window frame.

[0004] However, when using foam sealant for filling, the foam sealant itself is a flexible material and is prone to aging. The aged foam sealant will have a gap with the window frame, causing water leakage. In addition, foam sealant has high construction requirements and may even cause water leakage at the beginning of construction. When using mortar for filling, since the gap between the window frame and the wall is small and the outer periphery of the window frame is U-shaped, this actually forms a cavity with a small opening and a large internal space. During the filling process, it is difficult to completely fill the cavity gap between the window frame and the wall. The unfilled area will become a leak point when encountering wind and rain, affecting the construction quality and reducing the experience of the residents. Summary of the invention

[0005] In view of this, the present invention provides a window frame installation method to solve the problem in the prior art that after the window frame is placed in the window hole of the wall, the gap between the wall and the window frame is filled with mortar, and the gap between the window frame and the wall is not filled densely due to the U-shaped groove on the edge of the window frame, which is prone to water leakage.

[0006] A window frame installation method includes: before placing the window frame in a window hole in a wall, pre-filling the outer peripheral surface of the window frame with mortar to at least fill the U-shaped groove on the outer peripheral surface of the window frame; then placing the pre-filled window frame in the window hole in the wall; and re-filling the gap between the wall and the window frame with mortar.

[0007] Furthermore, when the outer peripheral surface of the window frame is pre-filled, the mortar is filled until it is flush with the notch of the U-shaped groove of the window frame.

[0008] Furthermore, before pre-filling the outer peripheral surface of the window frame, multiple window frames of the same model are stacked up and down and the edges of the multiple window frames are made flush, and the multiple window frames are filled simultaneously.

[0009] Furthermore, when the window frame is pre-filled, the filling is performed from the middle of the window frame to both sides.

[0010] Furthermore, when the window frame is pre-filled, the outer peripheral surface of the window frame is filled along one side of the window frame in a clockwise or counterclockwise direction.

[0011] Furthermore, before placing the window frame in the window hole of the wall, the window hole of the wall is roughened and the surface of the window hole is cleaned.

[0012] Furthermore, after the gap between the wall and the window frame is filled for a second time with mortar, a sealant is applied on the mortar surface between the window frame and the wall.

[0013] Further, when the sealant is applied to the mortar surface between the window frame and the wall, it is determined that the mortar is in a dry state.

[0014] Furthermore, the mortar used for pre-filling and the mortar used for secondary filling are both waterproof mortars.

[0015] Furthermore, before the window frame is placed in the window hole of the wall, a plaster cake is punched on the inner peripheral surface of the window hole to limit the position of the window frame.

[0016] The beneficial effect of the window frame installation method in the present invention is that the window frame installation method in the present invention is an improved invention, by filling the U-shaped groove on the outer peripheral surface of the window frame with mortar before the window frame is placed in the window hole of the wall, so that the outer peripheral surface of the window frame no longer has the U-shaped groove during installation but becomes a flat plane, and the gap between the flat plane and the inner peripheral surface of the window hole of the wall is no longer a cavity-shaped space with a small opening and a large internal space, but becomes a thin gap, which is convenient for filling with mortar during secondary filling. Since the window frame has not been installed in the window hole of the wall during pre-filling, the U-shaped groove on the outer peripheral surface of the window frame is exposed at this time, which is convenient for mortar filling, thereby solving the problem of filling the gap between the wall and the window frame with mortar after the window frame is placed in the window hole of the wall in the prior art, and the gap between the window frame and the wall is not filled densely due to the U-shaped groove on the edge of the window frame, which is easy to leak.

[0021] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module" and "component" can be used interchangeably.

[0022] In order to better understand the technical solution of the present invention, the window frame installation method of the present invention is described in detail below.

[0023] Before installing the window frame into the window opening in the wall, the window frame is first pre-filled, that is, the U-shaped groove on the outer peripheral surface of the window frame is filled with mortar. At this time, the outer peripheral surface of the window frame is in a flat form, and then placed in the window opening in the wall. At this time, there is a narrow gap between the window frame and the window opening instead of a cavity with a small opening and a large internal space, which is convenient for the final secondary filling. After that, the filling between the window frame and the window opening is completed through the secondary filling of mortar, and the connection reinforcement between the window frame and the wall is also completed.

[0024] Although there are many window frames in the whole building, they often only have a few specific models. In order to speed up the construction efficiency, when carrying out the construction, the window frames of the same model are first stacked up and down, and the edges of multiple window frames are made flush, and then the outer peripheral surface of the window frame is pre-filled. The size of a single window frame is small when pre-filled. When using tools such as spatulas to apply mortar to the edge of the window frame, it is easy to apply the mortar out of the U-shaped groove of the window frame, which not only causes waste of mortar, but also causes pollution to the window frame. After stacking multiple window frames up and down, the same side of different window frames forms a larger surface to be applied with mortar, which is convenient for workers to operate. At the same time, since the sides of two adjacent window frames are squeezed against each other after stacking up and down, it is also convenient to avoid the side of the window frame from being contaminated by mortar. In the process of applying mortar, it should be noted that only the U-shaped groove on the outer peripheral surface of the window frame is filled, so the mortar only needs to be filled to be flush with the notch of the U-shaped groove of the window frame, and the mortar can also be well combined with the window frame at this time. Of course, in other embodiments, each window frame can also be pre-filled separately. Alternatively, in other embodiments, the mortar may be filled beyond the edge of the window frame. At this time, it should be noted that before stacking the window frames up and down, cardboard or other things should be used to separate the window frames to prevent the window frames from sticking together due to the excess parts solidifying together.

[0025] When pre-filling the window frame, it is necessary to ensure that the filling is dense and there are no gaps. During operation, the filling starts from the middle of the window frame, and the plastering filling is carried out from the middle to both sides in sequence. Of course, in other embodiments, it is also possible to start from one side of the window frame and plaster the filling in a clockwise or counterclockwise direction. Regardless of the plastering filling method, the filling should be kept dense, especially in the corners of the window frame, and attention should be paid to filling to prevent the occurrence of cavities that affect the construction quality. After the pre-filling is completed, since multiple window frames are stacked up and down, they may not be used up at one time when used. For the pre-filled window frame, attention should be paid to watering and maintenance, and when the filling mortar has gaps, it should be filled in time. When the window frame manufacturer leaves the factory, a protective film is often attached to it. During the pre-filling process, attention should be paid to the protection of the protective film, so that even if a small amount of mortar appears on the side of the window frame, it will not contaminate the window frame.

[0026] After the pre-filling of the window frame is completed, before the window frame is placed in the window hole of the wall, in order to make the window frame and the wall more tightly combined, it is necessary to roughen the window hole of the wall, so that the inside of the window hole is easier to be tightly combined with the mortar, and after the mortar solidifies, it can be tightly combined with the wall, and the window frame is not easy to fall off. At the same time, the inner surface of the window hole is cleaned to remove the debris generated during the roughening process or the dust and gravel accumulated in the window hole. Of course, in other embodiments, if the inner surface of the window hole of the wall itself is relatively rough, the roughening process can be omitted at this time.

[0027] After that, the window frame needs to be installed and fixed. Specifically, before the window frame is installed, the three-line positioning method is used. The three lines refer to the horizontal elevation line, the vertical control line, and the entry and exit control line. The horizontal position is controlled by the horizontal elevation line; a line is drawn on the outer wall, and the center line of the window opening is used as the vertical control line to ensure the verticality of the window frame installation; the entry and exit control line can be directly controlled based on the plastering control line. The three-line positioning method belongs to the prior art and will not be described here. Before controlling the window frame to enter, plastering cakes can be punched at the four corners of the window opening, and the inner surface of the plastering cake can be used to limit the window frame to facilitate the window frame to enter the window opening of the wall. Of course, in other embodiments, the position of the plastering cake can also be changed, and it is only necessary to keep the window frame guided when it is in the window opening.

[0028] When the pre-filled window frame is moved into place, use wooden wedges to temporarily support and fix the window frame, and fine-tune the position of the window frame to meet the installation requirements. Then use connecting pieces or expansion bolts to fix the window frame. After the window frame is fixed, the wooden wedges need to be removed in time.

[0029] After the window frame is installed, there will inevitably be a certain gap between the window frame and the inner surface of the window hole, so it is necessary to use mortar to fill the gap for the second time. Specifically, before the second filling, the gap between the window frame and the window hole needs to be cleaned first, and the floating dust in the gap needs to be cleaned. Then, the gap between the window frame and the window hole needs to be filled with mortar. Since the outer surface of the window frame is a flat surface and the inner surface of the window hole is also a flat surface, the hollow space is an equidistant gap at this time, which is convenient for filling and compacting, avoiding the problem of incomplete filling caused by the small gap opening and large space in the past.

[0030] After the secondary filling, part of the mortar will overflow between the window frame and the window hole, so the overflowed part needs to be scraped off. After the mortar is dry, a neutral silicone sealant is applied to the outer surface of the mortar between the window frame and the window hole for additional waterproofing. There are many ways to determine whether the mortar is dry, such as by the solidification time, or by the morphology of the surface after solidification or other methods. The mortars in this embodiment are all waterproof mortars. Of course, if the window frame is an indoor window frame, other mortars can also be used at this time.

[0031] After the window frame is fixed and filled, the glass needs to be installed. The glass is installed in the window frame and sealed with sealant to prevent the glass from shaking when encountering strong winds. Finally, the protective film on the window frame can be peeled off. Of course, the protective film can also be kept until the interior decoration is completed.

[0032] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
