Abstract
Description
Technical Field
[0001] This invention belongs to the field of building installation technology, and in particular relates to a method for finishing the window edge when installing a thick stone curtain wall on the outside of a frameless window. Background Technology
[0002] With the continuous development of the construction industry, the use of glass curtain walls is gradually being restricted. More and more office and commercial buildings are using stone curtain walls for their facades. Because these buildings are generally quite tall, the thickness of the external stone curtain walls is usually quite large to maintain overall stability and aesthetic harmony. When installing a thick stone curtain wall, it is necessary to pre-set large window frame reduction parameters. Only in this way can sufficient thickness be ensured at the building openings for installing the stone curtain wall. If the thickness is insufficient, the stone curtain wall will obstruct window openings after installation. In this situation, the distance between the scaled-down window frame and the finished surface of the building opening is relatively large. Generally speaking, taking a 60mm profile window and 3cm thick stone as an example, the length of the window frame relative to the building opening can reach about 5cm on each side. When finishing the window edge with such a large thickness, if the general method of full plastering is used, since this exceeds the upper limit of plaster thickness (about 3.5cm), there is a high probability of leakage and cracking at the window edge. If concrete is used for finishing the window edge, it is not only difficult to operate, but also very costly, so this concrete method is generally not used.
[0003] In conclusion, for the case of installing thick stone curtain walls on the outside of frameless windows, the question of what window edge finishing construction method to adopt to avoid window edge leakage and cracking has become an urgent problem to be solved. Summary of the Invention
[0004] To address the aforementioned issues, this invention provides a method for finishing the window edge when installing a thick stone curtain wall on a frameless window, which can reduce the risk of cracking and leakage at the window location and save construction time.
[0005] The present invention provides a method for finishing the window edge when installing a thick stone curtain wall on a frameless window, comprising:
[0006] When setting up the template, use a pre-set template to surround the window opening, and enclose the space inside to match the stepped inverted curb.
[0007] Concrete is poured into the preset template to form a stepped curb around the window opening, wherein the stepped curb is located on the inside of the window to be installed.
[0008] Install a window frame at the window opening;
[0009] The exterior of the window is finished with a thick stone curtain wall.
[0010] Apply plaster to the inside of the window to a preset height.
[0011] Preferably, in the above-mentioned construction method for finishing the window edge when installing a thick stone curtain wall on a frameless window, when setting up the formwork, a pre-set formwork is used to surround the window opening, and an intermediate step is set below the position of the window to be installed in the space that is enclosed inside and matches the stepped inverted curb.
[0012] Preferably, in the above-mentioned construction method for finishing the window edge when installing a thick stone curtain wall on a frameless window, the method of using the space enclosed inside the preset template to match the stepped curb further includes:
[0013] The top and outer sides of the stepped inverted curb form a slope that descends from the inside out.
[0014] Preferably, in the above-mentioned construction method for finishing the window edge when installing a thick stone curtain wall on the outside of a frameless window, after forming a slope from the inside to the outside on the top and outer surfaces of the stepped curb, the method further includes:
[0015] Leveling is performed between the stepped curb and the window frame, followed by application of flexible waterproofing, and then plastering to the preset height.
[0016] Preferably, in the above-mentioned method for finishing the window edge when installing a thick stone curtain wall on a frameless window, before surrounding the window opening with a pre-set template, the method further includes:
[0017] The preset template is created based on the window opening size, window installation positioning, and node requirements.
[0018] Preferably, in the above-mentioned construction method for finishing the window edge when installing a thick stone curtain wall on a frameless window, the installation of the window frame at the window opening includes:
[0019] Install a window at the top of the intermediate step, controlling the inner edge of the window to be 5mm to 10mm lower than the outermost edge of the inner edge of the window and 10mm to 15mm higher than the surface of the intermediate step, and then apply expanding foam to the intermediate step.
[0020] Preferably, in the above-mentioned construction method for finishing the window edge when installing a thick stone curtain wall on a frameless window, after applying expanding foam on the intermediate step, flexible waterproof mortar and thermal insulation mortar are continued to be applied.
[0021] Preferably, in the above-mentioned method for finishing the window edge when installing a thick stone curtain wall on the outside of a frameless window, the finishing process using the thick stone curtain wall on the outside of the window is as follows:
[0022] Install the thick stone curtain wall so that the part of the thick stone curtain wall that contacts the window frame is 20mm to 25mm below the top surface of the window frame profile, and apply adhesive between the thick stone curtain wall and the window frame.

It can be seen that after setting the stepped curb on the inner side of the window to be installed, only a thinner layer of plaster is needed to achieve the finishing of the inner side of the window edge, eliminating the need for an excessively thick layer of plaster. This reduces the risk of cracking and leakage at the window location and saves construction time. Attached Figure Description

[0029] Figure 2 A cross-sectional view of the window edge finishing when installing a thick stone curtain wall on a frameless window. Detailed Implementation
[0030] The core of this invention is to provide a method for finishing the window edge when installing a thick stone curtain wall on a frameless window, which can reduce the risk of cracking and leakage at the window position and save construction time.
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] An example of the window edge finishing construction method provided by this invention for installing a thick stone curtain wall on the outside of a frameless window. Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of a method for finishing the window edge when installing a thick stone curtain wall on a frameless window, provided by the present invention. The method may include the following steps:
[0033] S1: When setting up the template, use a pre-set template to surround the window opening, and enclose the space inside to match the stepped inverted curb.
[0034] It should be noted that the pre-set template used in this step can be made of wood, steel, or aluminum alloy, and can be a single type of template or a combination of multiple templates; there are no restrictions here. Through this special processing of the pre-set template, a stepped curb is formed on the same plane around the window opening. The height of this stepped curb depends on the thickness of the stone curtain wall and the width of the window profile. Moreover, the positioning of the template needs to be precisely controlled according to the window installation positioning, keeping the positional deviation within 5mm to prevent the subsequent window installation failure due to template positional deviation.
[0035] S2: Pour concrete into the preset template to form a stepped curb around the window opening, wherein the stepped curb is located on the inside of the window to be installed;
[0036] It should be noted that this pre-cast template is used for pouring concrete simultaneously with the templates in other parts, thus forming a unified concrete structure. Specifically, around the window opening, this creates a stepped curb, and this stepped curb is located on the inner side of the window to be installed, meaning the concrete height on the inner side of the window is relatively high. This eliminates the need for extensive plastering in subsequent steps, achieving a seamless finish on the inner side of the window. The outer side of the window is finished using a thick stone curtain wall, requiring no plastering and therefore eliminating the risk of leakage or cracking. It should also be noted that a sufficiently large height difference must be maintained on the outer side of the window itself to avoid obstructing the installation of the stone curtain wall. (See reference...) Figure 2 , Figure 2The diagram shows the construction section of the window edge finishing when installing a thick stone curtain wall on a frameless window. It includes the window 1, the stepped curb 2, and the stone curtain wall 3. It can be clearly seen that the inner side of the window is no longer at the same height as the outer side of the window as in existing technologies. Instead, a stepped curb 2 is formed during the concrete pouring stage, which is higher than the outer side of the window. This eliminates the need to set the plaster thickness too large in subsequent steps, thus avoiding the formation of cracks.
[0037] S3: Install the window frame at the window opening;
[0038] It should be noted that, Figure 2 The installation position of the window is above the CD line. This explanation uses the center installation of a regular 60 series window as an example. Other types of windows are similar. In addition, the window installation center line needs to be marked out in advance. After the outer edge of the window is fixed, it should be lower than point B and higher than the finished surface of CD to facilitate the subsequent foaming and waterproof mortar construction.
[0039] S4: The outer side of the window is finished with a thick stone curtain wall;
[0040] It should be noted that continued reference is necessary. Figure 2 As can be seen, the thick stone curtain wall is attached to point I on the window frame. There is a certain height difference between point I and point H. This distance needs to take into account the width of the sealant and the width of the outer opening of the window frame to ensure that the window frame can be opened smoothly. Moreover, the height of the concrete upper surface EF on the outside of the window frame is very low, which leaves enough space for the installation of the thick stone curtain wall so that the installation of the thick stone curtain wall will not be obstructed.
[0041] S5: Apply plaster to the inside of the form up to the preset height.
[0042] It should be noted that when using the above method for construction, the positioning and layout must be strictly controlled to prevent large dimensional deviations that could cause the stone curtain wall to fail to adhere to the edge of the window profile, resulting in leakage. It is also necessary to prevent large dimensional deviations that could prevent the windows from opening after the stone curtain wall is installed.
[0043] As described above, in the embodiment of the window edge finishing construction method for installing a thick stone curtain wall on a frameless window provided by the present invention, the following steps are taken: During the formwork erection, a pre-set template is used to surround the window opening, forming a space that matches the stepped curb; concrete is poured into the pre-set template to form a stepped curb around the window opening, wherein the stepped curb is located on the inner side of the window to be installed; the window is installed in the window opening; the thick stone curtain wall is used to finish the window on the outer side; and plastering is applied to the inner side of the window to a pre-set height. Therefore, only a thinner layer of plaster is needed to achieve window edge finishing, thereby reducing the risk of cracking and leakage at the window location and saving construction time.
[0044] In a specific embodiment of the window edge finishing construction method for installing a thick stone curtain wall on a frameless window, when erecting the formwork, a pre-set formwork is used to surround the window opening. Within the enclosed space that matches the stepped curb, an intermediate step is also provided below the location of the window to be installed. It should be noted that, continuing to refer to... Figure 2 By setting an intermediate step CD, it can be placed closer to the window, thus making the overall structure more stable. Of course, this is a preferred solution, and it can be chosen according to actual needs. Moreover, the height of the intermediate step can also be set according to actual needs, and there is no restriction here.
[0045] In another specific embodiment of the window edge finishing construction method for installing a thick stone curtain wall on a frameless window, the space enclosed within a pre-set template to match the stepped curb can further include: forming a slope descending from the inside to the outside on the top and outer surfaces of the stepped curb. Figure 2 As can be seen from the diagram, the slope decreases from A to B, and there is also a downward slope from B to C. This slope ensures that water in the window area flows from inside the window to outside and is eventually drained away, thus preventing damp areas from forming due to water accumulation in the window area. Moreover, the slope can be set according to actual needs and is not restricted here.
[0046] In another specific embodiment of the window edge finishing construction method for installing a thick stone curtain wall on the exterior of the aforementioned frameless window, after forming a slope descending from the inside to the outside on the top and outer surfaces of the stepped curb, the following steps may also be included:
[0047] Continue to refer to Figure 2 Leveling is performed between the stepped inverted curb 2 and the window 1. Specifically, the plaster is leveled up to point A until the strength meets the requirements. Then, flexible waterproof 4 is applied, and plaster is applied to the preset height to reach the finished surface. It can be seen that the height of plastering required at this time is very low compared to existing technologies. Generally, the plastering thickness can be reduced to less than 3cm, which can effectively prevent the occurrence of cracks.
[0048] In a preferred embodiment of the window edge finishing construction method for installing a thick stone curtain wall on a frameless window, the following steps may be included before surrounding the window opening with a pre-set template:
[0049] Pre-designed templates are made according to the window opening dimensions, window installation positioning, and node requirements. Specifically, before construction, the window opening dimensions and installation positioning (centering or other installation methods) are determined first. Then, the templates are processed according to the node requirements. It is important to control the thickness of the template overlaps. The shape of the concrete pouring can be controlled by the overlapping thickness of the wooden molds, and the templates are processed according to the node dimensions and design requirements in the drawings.
[0050] In addition, in the above-mentioned construction method for finishing the window edge when installing a thick stone curtain wall on a frameless window, the installation of the window frame at the window opening can specifically include the following steps:
[0051] Continue to refer to Figure 2 Install window 1 above the middle step CD. The inner edge of window 1 should be 5mm to 10mm lower than the outermost B of the inner curb 2 of window 1. This ensures water can only flow from inside the window outwards, preventing water from flowing inwards and guaranteeing better waterproofing. Furthermore, the inner edge of window 1 should be 10mm to 15mm higher than the surface of the middle step CD to allow sufficient height for applying expanding foam, facilitating its application. Then, apply expanding foam 5 to the middle step CD. After applying expanding foam 5, continue applying flexible waterproof mortar and thermal insulation mortar 6 to further enhance waterproofing and insulation performance. A slope needs to be created during application, and the thickness and width of the mortar should ensure smooth installation of the stone curtain wall without obstruction.
[0052] In another preferred embodiment of the window edge finishing construction method when installing a thick stone curtain wall on the outside of the aforementioned frameless window, the finishing of the window edge using the thick stone curtain wall on the outside of the window 1 can be specifically as follows:
[0053] Install the thick stone curtain wall 3, ensuring that the contact point between the thick stone curtain wall 3 and the window frame 1 is 20mm to 25mm below the top surface of the window frame 1's profile. Apply sealant between the thick stone curtain wall 3 and the window frame 1. Taking a standard 60mm window frame profile as an example, the stone thickness in the thick stone curtain wall is generally 30mm, and the outer opening height of the standard 60mm window frame profile is 28mm. Considering the operable sash and sealant application, the stone must be at least 20mm exposed on the window frame profile. Therefore, the inner side of the finished stone surface must be at least 20mm inside the outer opening of the window frame. Thus, the plaster thickness must be controlled to meet this distance requirement.
[0054] In another preferred embodiment of the window edge finishing construction method for installing a thick stone curtain wall on the exterior of the aforementioned frameless window, after plastering the inner side of the window 1 to a preset height, the following step can be included: conducting a water spray test on the window 1. In this case, the waterproof effect of the window edge finishing can be guaranteed to be good enough. If the water spray test fails, rework is required until the test is passed.
[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
