Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a fixing device for building window frames and its construction method. Background Technology

[0002] When installing window frames in residential buildings, the window opening walls have tongue and groove joints, so the window frame fixing clips need to be fixed with nails from the inside. However, in projects delivered as bare shells, the clips cannot be concealed, resulting in poor visual quality and affecting delivery. If plaster is used to conceal them, the labor cost is high; if the plaster is too thin, it is prone to cracking and falling off; if it is too thick, it covers too much of the window frame, making it impossible to carry out later decoration work. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a fixing device for building window frames and its construction method are provided to solve the problem that the pull tabs cannot be hidden in the existing window frame installation of residential buildings.

[0004] To achieve the above objectives, a fixing device for a building window frame is provided, comprising:

[0005] The support is provided with multiple supports installed on the circumferential side of the window frame. The multiple supports are spaced apart along the circumferential direction of the window frame. Each support has an insertion slot, which is arranged along the axial direction of the window frame.

[0006] An insert strip, one end of which is slidably disposed in the insert opening, and the other end of which is supported on the wall of the window opening;

[0007] An elastic locking member is provided, one end of which is connected to the support. A plurality of toothed grooves are formed on one side of the insert strip, and the plurality of toothed grooves are arranged along the length direction of the insert strip. The other end of the elastic locking member is inserted into a toothed groove to lock the insert strip.

[0008] Furthermore, the other end of the insert strip is mounted on the wall of the window opening via a gasket.

[0009] Furthermore, the insert strip and the gasket are fixed to the hole wall by nails.

[0010] Furthermore, one end of the insert strip is provided with an anti-detachment member, which abuts against the outer side of the support.

[0011] This invention provides a construction method for a fixing device for a building window frame, comprising the following steps:

[0012] Multiple supports are installed on the circumferential side of the window frame, and the multiple supports are spaced apart along the circumferential direction of the window frame, such that the insertion holes of the supports are arranged along the axial direction of the window frame.

[0013] Slide one end of the insert strip into the insert opening;

[0014] The window frame is fitted into the window opening, and the other end of the insert strip is placed at the tongue and groove of the window opening wall;

[0015] Pull one end of the insert strip and push the window frame toward the tongue and groove. The multiple supports slide to the other end of the insert strip so that the window frame abuts against the tongue and groove. After the window frame abuts against the tongue and groove, the other end of the elastic locking member is inserted into a toothed groove of the insert strip to lock the insert strip.

[0016] The gap between the inner side of the window frame and the tongue and groove joint is filled with mortar.

[0017] The beneficial effects of the present invention are that the fixing device for the building window frame of the present invention, through the cooperation of the support, the insert strip and the elastic locking element, realizes the rapid positioning and reliable locking of the window frame in the window opening. During the installation process, there is no need to use traditional pull tabs, avoiding the problem of exposed pull tabs. Therefore, there is no need to plaster and conceal them on the inside, which significantly improves the appearance quality of the window frame after installation. It is especially suitable for projects delivered in bare shell condition.

[0018] The fixing device for the building window frame of the present invention has one end of the insert strip slidably installed in the insert opening of the support, and one-way locking is achieved by the engagement of the elastic locking element and the tooth groove. During construction, the window frame can be adjusted and fixed simply by pushing it towards the interior side. The operation is simple, efficient and requires low skill level from the workers.

[0019] The support and insert strip of the fixing device for the building window frame of the present invention can be prefabricated as an integrated unit during the window frame production stage and shipped out at the same time as the window frame. No additional processing is required on site, which reduces the number of on-site operation procedures and material types, and lowers construction costs. At the same time, the insert strip and other components can be naturally concealed in the subsequent external wall insulation and plastering construction, without the need for separate treatment.

[0020] The fixing device for the building window frame of the present invention only requires mortar grouting between the inner side of the window frame and the tongue and groove, without the need for large-area plastering. This avoids problems such as cracking due to excessively thin plaster or obscuring the window frame due to excessively thick plaster, providing good construction conditions for later decoration and improving the overall project quality and economy.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figures 1 to 5 As shown, the present invention provides a fixing device for a building window frame, comprising: a support 1, an insert strip 2, and an elastic locking member 3.

[0037] In this embodiment, the support is plate-shaped. For example... Figure 5 As shown, after the window frame is installed in the window opening, a gap is formed between the circumferential side of the window frame and the wall of the window opening. The thickness of the support is slightly smaller than this gap.

[0038] Multiple supports 1 are installed on the circumferential side of the window frame 5. The multiple supports 1 are spaced apart along the circumferential direction of the window frame 5. After the window frame is installed in the window opening, the window frame can also be adjusted in position along the axial direction of the window opening. In this embodiment, the window frame is installed in the window opening from the outdoor side, and then the position of the window frame is adjusted towards the indoor side so that the window frame moves toward the tongue and groove in the window opening and fits.

[0039] In this embodiment, the support 1 has an insertion slot 10. The insertion slot 10 is arranged along the axial direction of the window frame 5.

[0040] The thickness of the insert strip is adapted to the thickness of the insert opening. One end of the insert strip 2 is slidably placed in the insert opening 10. The other end of the insert strip 2 is supported on the wall 6 of the window opening.

[0041] In a preferred embodiment, the other end of the insert strip 2 is mounted on the wall 6 of the window opening via a gasket 4.

[0042] In this embodiment, the insert strip 2 and the gasket 4 are fixed to the hole wall 6 by a nail 41. The gasket supports the insert strip, allowing the support to slide along the length of the insert strip.

[0043] The elastic locking element 3 is an elastic metal locking element. Correspondingly, the support is a metal part. The elastic locking element and the support are integrally cast.

[0044] Specifically, one end of the resilient locking member 3 is connected to the support 1. Multiple toothed grooves 20 are formed on one side of the insert strip 2. These grooves 20 are arranged along the length of the insert strip 2. The other end of the resilient locking member 3 is inserted into one of the toothed grooves 20 to lock the insert strip 2.

[0045] See Figure 3 and Figure 5 As shown, Figure 5 The image shows the initial position of the window frame within the window opening. Figure 3 The diagram shows the state of the window frame after its position has been adjusted in the axial direction of the window opening. When adjusting the position of the window frame, the support slides from one end of the insert strip to the other end of the insert strip. After the window frame is adjusted into place, the elastic locking element can be stably inserted into a toothed groove, thereby locking the insert strip, so that the window frame is stably set in the window opening and abuts against the tongue and groove of the window opening.

[0046] Continue to combine Figure 3 and Figure 5 As shown, an anti-detachment member 21 is formed at one end of the insert strip 2. The anti-detachment member 21 abuts against the outside of the support 1. The size of the anti-detachment member is larger than the size of the insert opening. The anti-detachment member abuts against the outside of the support to prevent the support from slipping off the insert strip.

[0047] This invention provides a construction method for a fixing device for a building window frame, comprising the following steps:

[0048] S1. Multiple supports 1 are installed on the circumferential side of the window frame 5. The multiple supports 1 are spaced apart along the circumferential direction of the window frame 5, so that the insertion slots 10 of the supports 1 are set along the axial direction of the window frame 5.

[0049] Before construction, the necessary preparatory work includes:

[0050] Before processing the window frame, check the window opening dimensions and reserve space for fixing components.

[0051] The supports and insert strips are manufactured and processed by the window frame manufacturer and shipped together with the window frame for on-site installation.

[0052] Inspect and polish the window openings to ensure the tongue and groove joints are flat and straight, allowing for smooth installation of the window frame.

[0053] The insert strip is made of Q235 steel with a thickness of not less than 1.5mm, a width of not less than 20mm, and a length greater than the thickness of the window frame by 50mm.

[0054] The support material is made of Q235 steel lining with a thickness of not less than 1.5mm, and the anti-detachment tongue must have strong rigidity and elasticity.

[0055] The gasket material is made of iron sheet. The gasket uses the impact force of nailing with a nail gun to prevent it from being squeezed and deformed. Its main function is to increase the distance between the insert strip (3) and the wall of the concrete window opening, so that the support can slide on the insert strip.

[0056] The diameter of the nail should be no less than 4mm and the length should be no less than 40mm. One pull tab should be fixed with two nails.

[0057] S2. Slide one end of the insert strip 2 into the insert opening 10.

[0058] S3. The window frame 5 is embedded in the window opening, and the other end of the insert strip 2 is placed at the tongue and groove 60 of the window opening wall 6.

[0059] When installing the window frame on site, slide all the supports on the window frame to one end of the insert strip. Then align the window frame with the window opening.

[0060] Install the window frame into the window opening. Then, place the other end of the insert strip into the tongue and groove joint. After placing a gasket at the other end of the insert strip, fix it to the wall of the opening with a nail gun.

[0061] S4. Pull one end of the insert strip 2 and push the window frame 5 toward the tongue and groove 60. Multiple supports 1 slide to the other end of the insert strip 2 so that the window frame 5 abuts against the tongue and groove 60. After the window frame 5 abuts against the tongue and groove 60, the other end of the elastic locking member 3 is inserted into a toothed groove 20 of the insert strip 2 to lock the insert strip 2.

[0062] After securing all the insert strips, pull the window frame parallel to the inside to the tongue and groove joint.

[0063] S5. Mortar grouting is applied to the gap between the inner side of the window frame 5 and the tongue and groove joint 60.

[0064] The gap between the window frame and the concrete window opening is filled with expanding foam. The inside of the window frame is grouted with waterproof mortar along the tongue and groove edge, and one end of the insert strip is concealed during the external wall insulation and plastering construction.

[0065] This invention integrates the support and insert strip into the window frame. After aligning the window frame with the window opening, the insert strip is fixed with nails. The window frame position is then adjusted by pushing it towards the interior side. After installation, the gap between the window opening and the window frame is small, and the insert strip is concealed under the window frame, resulting in a good visual quality. Only grouting is required at the inside of the window frame and the tongue and groove joint. The inside of the window frame does not need to be plastered to conceal the insert strip, thus reducing construction costs.

[0066] The fixing device for building window frames of the present invention achieves rapid positioning and reliable locking of the window frame in the window opening through the cooperation of the support, insert strip and elastic locking component. The installation process does not require the use of traditional pull tabs, avoiding the problem of exposed pull tabs, and thus eliminating the need for plastering to conceal them on the inside, which significantly improves the appearance quality of the window frame after installation, and is especially suitable for projects delivered in bare shell condition.

[0067] The fixing device for the building window frame of the present invention has one end of the insert strip slidably installed in the insert opening of the support, and one-way locking is achieved by the engagement of the elastic locking element and the tooth groove. During construction, the window frame can be adjusted and fixed simply by pushing it towards the interior side. The operation is simple, efficient and requires low skill level from the workers.

[0068] The insert strip of the fixing device for the building window frame of the present invention is mounted on the window opening wall by means of a gasket and fixed by a nail. The support can slide smoothly along the length of the insert strip, ensuring the stability and accuracy of the window frame during adjustment, so that the window frame can fit tightly against the tongue and groove, reducing the gap between the window frame and the window opening, which is beneficial to subsequent sealing and waterproofing treatment.

[0069] The support and insert strip of the fixing device for the building window frame of the present invention can be prefabricated as an integrated unit during the window frame production stage and shipped out at the same time as the window frame. No additional processing is required on site, which reduces the number of on-site operation procedures and material types, and lowers construction costs. At the same time, the insert strip and other components can be naturally concealed in the subsequent external wall insulation and plastering construction, without the need for separate treatment.

[0070] The fixing device for the building window frame of the present invention only requires mortar grouting between the inner side of the window frame and the tongue and groove, without the need for large-area plastering. This avoids problems such as cracking due to excessively thin plaster or obscuring the window frame due to excessively thick plaster, providing good construction conditions for later decoration and improving the overall project quality and economy.

[0071] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
