Description

Technical Field

[0001] This utility model relates to the field of door and window construction, specifically a door and window structure that can be combined with a wall without formwork. Background Technology

[0002] Door and window frames are installed on the walls of door and window openings. They can protrude from the exterior wall to form a frame or be flush with the exterior wall. They are used to protect and decorate door and window frames. In the prior art, door and window frames and door and window frames are separate parts. The installation of this frame-and-frame separation structure requires that openings be planned and reserved in advance on the target wall for the installation of door and window frames and door and window frames, and the door and window frames and door and window frames are installed separately.

[0003] When prefabricating openings in a wall for installation, the process typically involves first setting up side formwork for the door and window openings while pouring the concrete wall. After the concrete wall is poured, the side formwork is removed to create the openings for the doors and windows. The door and window frames are then fixed inside the openings. Cement mortar is used to fill the gaps between the openings and the frames, and the openings are then plastered and finished. Decorative moldings such as door and window frames are installed, and finally, paint is applied to complete the work. The door and window frames are then installed in stages. During frame installation, the frames are usually installed first. After the mortar and foaming agent between the frame and the opening wall have dried and hardened, waterproofing is applied between the wall and the frame. The door and window frames are then installed, and further waterproofing is applied at the joints between the frames and the door / window frame.

[0004] The overall construction process requires a long period, and numerous uncertainties exist during construction. The quality of the project is directly affected by the skill of the operators, making it difficult to improve production efficiency and significantly increasing project costs. Furthermore, because the installation is done in stages, waterproofing must be applied in each stage, further increasing the complexity of on-site construction. If any waterproofing and sealing process is not performed properly, problems such as water seepage and air leakage will inevitably occur. Utility Model Content

[0020] II. The protective plate is wrapped around the wall body and connected with the wall body through the folded edge, thereby greatly increasing the integration of the combination of the protective plate and the door and window frame and the wall body. Only the combination and splicing part of the protective plate and the door and window frame needs to be waterproofed and sealed, and the horizontal height of the bottom inner protective plate is higher than that of the bottom outer protective plate. The structure has the effect of draining water to the side of the outer protective plate, which can effectively prevent rainwater from entering from the side of the outer protective plate and significantly improve the waterproof sealing performance of the door and window.

[0021] III. The inner protective plate of the protective plate is made of low-thermal-conductivity material and is separated from the outer protective plate, which can effectively reduce the heat conduction exchange between the two sides of the door and window through the sleeve and maintain the stability of the indoor temperature.

[0022] IV. The side wall of the sealing groove on the folded edge is inclined to one side of the door and window frame to form a drip eave for draining water. When the rainwater flowing along the wall surface reaches the eave, a rain curtain waterfall is formed, which increases the speed and smoothness of water drainage. BRIEF DESCRIPTION OF DRAWINGS

[0035] As Figure 4 shown, the protective plate 2 comprises an outer protective plate 21 and an inner protective plate 22, and the outer protective plate 21 and the inner protective plate 22 are thin plate parts arranged side by side and fixed by pouring on the wall of the door and window hole. The outer protective plate 21 and the inner protective plate 22 are not connected, and form a gap gap at the side-by-side position. On both sides of the gap gap, the outer protective plate 21 and the inner protective plate 22 each have a mounting groove 24, which is recessed from the outer protective plate 21 and the inner protective plate 22 to the side of the door and window hole wall, and the mounting groove 24 is embedded in the wall after pouring and installation.

[0036] As Figure 2 shown, the outer protective plate 21 and the inner protective plate 22 are each provided with a vertical downward folded edge 23 on the outer side, and the folded edges 23 on both sides are attached to the facade of the wall after pouring and installation. A plurality of support frames 3 are arranged in the semi-enclosed structure composed of the folded edges 23 on both sides and the protective plate 2 at uniform intervals, and the top of the support frame 3 is fixedly connected with the bottom of the outer protective plate 21 and the inner protective plate 22 by screws or welding, and the left and right sides of the support frame 3 are respectively fixedly connected with the inner sides of the folded edges 23 on both sides, thereby providing fixed support for the whole outer protective plate 21 and inner protective plate 22 and pouring the whole into the wall after installation.

[0037] The door / window frame 1 is fitted with glass and / or a window sash. Two downward-protruding mounting ribs 11 are formed along the bottom edge of the door / window frame 1. These two mounting ribs 11 correspond to mounting grooves 24 on the outer protective plate 21 and the inner protective plate 22, and engage with the two mounting grooves 24 to fix the position of the outer protective plate 21 and the inner protective plate 22. Figure 5 As shown, the two mounting ribs 11 have protrusions at their bottom ends that face the middle of the door and window frame 1. The protrusions abut against the side walls of the two mounting grooves 24 respectively, so as to achieve the fixed installation of the door and window frame 1.

[0038] like Figure 3 As shown, the two folded edges 23 are recessed inward, forming embedded sealing grooves 25. The width of the sealing groove 25 tends to decrease from the inside of the groove to the opening. After pouring and installation, the sealing groove 25 is embedded inside the wall. During pouring and installation, a sealing strip is embedded in the sealing groove 25, and the sealing strip is fitted and sealed with the wall side formwork to prevent concrete leakage; or an elastic sealing strip is attached to the outer wall of the folded edge 23, and the elastic sealing strip is fitted and sealed with the wall side formwork; or both the outer wall surface of the folded edge 23 and the wall side formwork of the wall pouring are made with flat surfaces, and the flat surfaces of the two are directly fitted and sealed.

[0039] The bottom of the two side flanges 23 is folded inward and inclined towards the sealing groove 25 to form a hook-shaped flange 231. After the flange 231 is poured and installed, it is embedded in the wall and hooks the wall; or a thickened protruding structure is made at the outer end of the flange 23 to be embedded in the wall to achieve a firm connection with the wall.

[0040] Specific Implementation Example 2: Based on Specific Implementation Example 1, such as Figure 3 As shown, the upper sidewall of the sealing groove 25 slopes towards the door / window frame 1, and the cross-sectional width of the sealing groove 25 tends to narrow from the inside of the groove to the opening, forming a drip edge for drainage at the sealing groove 25. During casting and installation, the sealing strip embedded in the sealing groove 25 is fixed by the sidewall of the groove opening to prevent the sealing strip from slipping and ensure sealing performance.

[0041] Specific Embodiment 3: Based on Specific Embodiment 2, the horizontal height of the bottom inner protective plate 22 is higher than that of the bottom outer protective plate 21, so that rainwater can be automatically discharged outward under the effect of the height difference.

[0042] Specific Implementation Example 4: Based on Specific Implementation Example 3, such as Figures 7-8 As shown, when there is no folded edge 23 structure on both sides of the protective plate 2, a rubber strip 26 is provided at the end where the protective plate 23 is connected to the wall. The rubber strip 26 is directly attached to the wall side formwork for sealing during the wall pouring to prevent concrete leakage.
