Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a structure of a broken bridge narrow frame window screen integrated with a window sill and a flat window Background Art

[0002] In the prior art, for the outdoor window sill of a window, ceramic tiles identical to the exterior wall are generally used for paving, and then sealant is applied at the connection between the window frame and the outdoor window sill to prevent rainwater from seeping in. However, this common method has great deficiencies: First, the position of the outdoor window sill is relatively narrow, making it difficult to lay ceramic tiles, with poor paving flatness, high construction difficulty and low efficiency; Second, the sealant is exposed outdoors for a long time, subjected to sun and rain, and is extremely easy to age and leak; Third, the boundary between the window sill and the window is distinct, making it difficult for the window to form a large-scale integrated effect and affecting the overall style of the building facade.

[0003] The Chinese utility model patent document with the application number 201821025166.9 and the title "Airtight Structure between a Broken Bridge Aluminum Alloy Window and a Wall of an Assembled Steel Structure Residential Building" discloses a technical solution. In this technical solution, the aluminum alloy window is fixed on the window sill plate through an extension frame at the bottom. An aluminum drip plate is fixed on the outer side surface of the extension frame by screws. The aluminum drip plate inclines outward and extends to the outside of the window sill plate, completely covering the window sill plate located outdoors. Although this technology can solve the above technical problems, there are still the following technical problems in the use process:

[0004] First, the aluminum drip plate is fixed on the side surface of the extension frame by self-tapping screws. In this way, many screws must be drilled along the length direction of the extension frame during installation, which not only has a large workload and low installation efficiency, but also damages the mechanical strength of the extension frame, thereby affecting the stability of the window; In order to protect the screw head from air and rain erosion, a layer of glass glue needs to be applied outside the screw head. However, since the screw head protrudes from the aluminum plate surface, it is not easy to smear the surface of the glass glue layer smoothly during the glue application process, and more glass glue is consumed.

[0005] Second, in order to enhance the compressive capacity of the aluminum drip plate and fix the aluminum drip plate more firmly on the outdoor window sill, before installing the aluminum drip plate, it is necessary to first lay cement on the outdoor window sill and then lay the aluminum drip plate on it; However, due to the different surface structures and densities of the aluminum drip plate and the cement, the connection force between the two is small, and air pockets are likely to be generated at the connection surface during the laying process, resulting in insufficient installation strength of the aluminum drip plate. In this way, when encountering strong wind weather, the aluminum drip plate is easily blown up by strong wind, causing potential safety hazards.

[0006] In view of the above technical problems existing in the prior art, the applicant believes that it is very necessary to improve the technology to provide a window structure that is easier to install and has better stability and safety. Summary of the Utility Model

[0007] The purpose of the present utility model is to solve the above problems and deficiencies, and provide a flat open window structure with an integrated broken bridge narrow frame and window screen connected to the window sill. Through a unique window sill component, it has the advantages of being easy to install, better stability and safety.

[0008] The technical solution of the present utility model is realized as follows: A flat open window structure with an integrated broken bridge narrow frame and window screen connected to the window sill, including a window body, an installation bottom frame, and a fixed frame. The installation bottom frame is fixedly installed on the fixed frame, and the window body is fixedly connected to the installation bottom frame. A window sill component is also provided on the outer side of the window body. The window sill component includes a base and a window sill plate buckled on the base. Its characteristics are: The inner bottom edge of the base is clamped between the installation bottom frame and the fixed frame, and the inner side surface of the base is in close contact and fits together with the side surface of the installation bottom frame along its length direction; An embedding groove horizontally arranged along its length direction is also provided above the inner end of the base, and the inner edge of the window sill plate is embedded with the embedding groove; A water retaining part arranged along its length direction is also provided on the outer side edge of the window sill plate; A first support part for supporting the base is also provided on the bottom surface of the window sill plate located inside the water retaining part; A second support part for enhancing the compressive capacity of the window sill plate is also provided between the bottom surface of the window sill plate and the top surface of the base.

[0009] Further, a connecting part is provided on the inner bottom edge of the base, and the connecting part is clamped and fixed between the installation bottom frame and the fixed frame.

[0010] Still further, the base includes a vertical plate and a horizontal plate. The vertical plate is in close contact and fits together with the side surface of the installation bottom frame; The second support part is arranged on the horizontal plate and is integrally provided with the horizontal plate; The connecting part is arranged on the outer bottom edge of the vertical plate.

[0011] Still further, the embedding groove is arranged on the top edge of the vertical plate.

[0012] Even further, the embedding groove is composed of an upper convex edge integrally formed on the upper side surface of the upper end of the vertical plate and a lower supporting plate, and an inclined surface inclined outward is also provided on the top of the upper convex edge. The horizontal width of the upper convex edge is smaller than the horizontal width of the lower supporting plate.

[0013] Even further, an installation angle is formed between the first support part and the water retaining part, and a serrated structure is also provided on the side surface of the installation angle.

[0014] Even further, an inner convex edge is also provided on the inner corner of the water retaining part.

[0015] Advantages of the present utility model:

[0016] First of all, the window sill assembly is clamped between the installation bottom frame and the fixed frame through the inner bottom edge of its base, and the window sill board is embedded with the base through the embedding groove; in this way, when installing the window sill assembly, there is no need to drive screws, and the installation work of the window sill assembly can also be completed indoors, thus greatly accelerating the construction speed. At the same time, damage to the installation bottom frame can also be avoided, which is beneficial to improving the stability of the window.

[0017] Secondly, the window sill assembly and the installation bottom frame form an integral whole. In this way, when installing, the window sill assembly can be embedded in the wall together with the installation bottom frame, so that the window sill assembly can be very firmly installed on the wall. Even in strong wind weather, the window sill assembly will not be blown up by the strong wind, having very good safety performance; and through the restriction of the groove wall of the installation groove, the window sill assembly and the installation bottom frame can be tightly pressed against each other during the installation process, making the connection between the two have very good sealing performance. Even if the outer sealant ages, it will not affect the sealing performance of the window.

[0018] In addition, the window sill board is supported by the first support part, the second support part, and the base, so that it has good compressive capacity. In this way, there is no need to fill cement between the window sill board and the base, thus greatly improving the construction speed and reducing the construction cost; at the same time, the whole window sill assembly is a hollow structure, thus reducing the material consumption, making the product lightweight, and further being beneficial to cost control and facilitating the installation of the window sill assembly.

[0022] In order to enable the personnel in the field to better understand the technical solution of the present utility model, the technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings of the present utility model.

[0023] Such as Figures 1 to 3As shown in the figure, the utility model provides a structure of a broken bridge narrow frame window screen integrated with a window sill flat window, which includes a window body 1, an installation bottom frame 2, and a fixed frame 3. The installation bottom frame 2 is fixedly installed on the fixed frame 3, and the window body 1 is fixedly connected to the installation bottom frame 2. A window sill assembly 40 is further provided on the outer side surface of the window body 1. The window sill assembly 40 includes a base 4 and a window sill board 5 buckled on the base 4. To achieve the purpose proposed by the utility model, the inner bottom edge of the base 4 is clamped between the installation bottom frame 2 and the fixed frame 3, and the inner side surface of the base 4 and the side surface of the installation bottom frame 2 are tightly abutted and attached to each other along their length directions. An embedding groove 411 horizontally arranged along its length direction is further provided above the inner end of the base 4, and the inner edge of the window sill board 5 is embedded with the embedding groove 411. A water retaining portion 51 arranged along its length direction is further provided on the outer side edge of the window sill board 5. A first supporting portion 52 for supporting the base 4 is further provided on the bottom surface of the window sill board 5 inside the water retaining portion 51. A second supporting portion 44 for enhancing the compressive capacity of the window sill board 5 is further provided between the bottom surface of the window sill board 5 and the top surface of the base 4. In this way, the window sill assembly 40 and the installation bottom frame 2 can form a whole. During construction, first, the fixed frame 3 is buried in the wall body, and then an installation groove for installing the installation bottom frame 2 and the window sill assembly 40 is constructed on the wall body, so that the window sill assembly 40 can be embedded in the wall body together with the installation bottom frame 2, making the window sill assembly 40 very firmly installed on the wall body. Even in strong wind weather, the window sill assembly 40 will not be blown up by the strong wind, having very good safety performance.

[0024] As Figure 1 , 2 shown, a connecting portion 43 is provided on the inner bottom edge of the base 4, and the connecting portion 43 is clamped and fixed between the installation bottom frame 2 and the fixed frame 3. The connecting portion 43 is a long strip plate arranged along the length direction of the inner bottom edge of the base 4, so that the fixation of the base 4 can be realized through the connecting portion 43.

[0025] Furthermore, as Figure 1 , 2 shown, the base 4 includes a vertical plate 41 and a horizontal plate 42. The vertical plate 41 and the side surface of the installation bottom frame 2 are tightly abutted and attached to each other. The second supporting portion 44 is arranged on the horizontal plate 42 and is integrally provided with the horizontal plate 42. The connecting portion 43 is arranged on the outer bottom edge of the vertical plate 41. In this way, the base 4 is installed in the wall body through the horizontal plate 42, and then the base 4 can be connected to the window sill board 5 through the vertical plate 41 to form the window sill assembly 4.

[0026] As Figure 1 , 2As shown, the splicing groove 411 is provided on the top edge of the vertical plate 41, so that the window sill plate 5 can be installed on the top surface of the base 4 through the splicing groove 411.

[0027] As Figure 1 , 2 shown, the splicing groove 411 is formed by combining the upper convex edge 412 and the lower supporting plate 413 integrally formed on the side surface of the upper end of the vertical plate 41. The top of the upper convex edge 412 is also provided with an inclined surface that slopes outward. The horizontal width of the upper convex edge 412 is smaller than the horizontal width of the lower supporting plate 413. In this way, the lower supporting plate 413 can provide a relatively stable supporting effect on the window sill plate 5, and the inclined surface of the upper convex edge 412 can facilitate the outward flow of rainwater, thereby contributing to improving the waterproof performance of the window sill assembly 5.

[0028] As Figure 1 , 3 shown, an installation angle 53 is formed between the first supporting portion 52 and the water retaining portion 51. A serrated structure 54 is also provided on the side surface of the installation angle 53. During installation, the groove wall of the installation groove on the wall is clamped in the installation angle 53. The tips of the teeth of the serrated structure 54 can penetrate into the inner part of the groove wall, so that the installation angle 53 can bite on the groove wall, further enhancing the installation stability of the window sill plate 5. And the water retaining portion 51 extends to the outside of the wall, so that the window body 1 and the window sill assembly form a whole, and the window sill assembly 40 can completely cover the outer window sill. In this way, not only is it no longer necessary to lay tiles on the outer window sill, reducing the construction cost, but also the appearance quality of the building can be greatly improved.

[0029] As Figure 1 , 3 shown, an inner convex edge 55 is also provided at the inner corner of the water retaining portion 51. In this way, the inner convex edge 55 can form a sealing and water stopping structure between the water retaining portion 51 and the wall, preventing rainwater from seeping into the wall. And during installation, the inner convex edge 55 and the water retaining portion 51 will also generate a reset elastic force together, so that the two are elastically pressed against the wall, thereby further enhancing the installation stability of the window sill plate 5. And caulking for sealing can also be omitted, accelerating the construction speed.
