Description

Technical Field

[0001] The invention relates to the field of door and window construction, and more specifically to a prefabricated wall and door and window formwork-free combined structure and an installation method thereof. Background Art

[0002] With the rapid development of my country's construction industry and the increasing requirements of residents for housing quality, the corresponding specifications and requirements for construction have gradually improved. In the latest standards, the overall quality standards for door and window construction and installation have been refined and improved more than in the past. In the latest standards, strict classification of air tightness, water tightness, and wind pressure resistance of building doors and windows is carried out, and corresponding construction quality standards are defined to regulate many problems existing in the installation of traditional building doors and windows.

[0003] In the installation and construction of traditional building doors and windows, it is usually necessary to reserve installation holes slightly larger than the doors and windows in advance during the overall wall construction, waiting for the subsequent installation of door and window frames and window sashes, and the gap between the installation hole and the embedded window frame is sealed by waterproofing procedures such as filling with waterproof mortar, spraying waterproof coatings, and applying structural adhesive. However, due to the substandard process level of the waterproofing process in actual construction and natural aging during subsequent maintenance and use, leakage problems will inevitably occur in the gap during strong winds and rainstorms.

[0004] In the existing improved patent technology (CN202111388425.0), a method for installing window frame connectors in advance in the wall where doors and windows are installed is proposed, so as to realize the integrated overall structural design of the existing door and window outer frame cavity and the cavity material pre-installed in the building wall, and increase the sealing and waterproof performance of the doors and windows after installation. However, its technical solution still does not deviate from the traditional construction route of later combination of window frame and wall (in this technology, the sub-frame pre-installed in the wall). There is still a gap between the wall and the window frame when they are combined, which needs to be waterproofed and blocked. In addition, the combined installation of the window frame connection parts and the waterproofing process in its solution require a lot of installation time, which greatly increases the time cost of on-site construction. Summary of the invention

[0005] In summary, a new prefabricated wall and door and window formwork-free combination structure is proposed to solve the problem in the prior art that the window frame installation gap destroys the overall sealing of the doors and windows, and to provide an installation method for the prefabricated wall and door and window formwork-free combination structure to shorten the installation time.

[0006] Door and window frames are installed on the two vertical surfaces of the 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.

[0007] The invention discloses a combined structure of a wall, a door and a window, comprising a door and a window system and a wall.

[0008] The door and window system comprises a door and window frame and a door and window body.

[0009] One or both sides of the door and window frame connected to the wall are provided with vertically folded edges, at least one folded edge is provided with a sealing portion on the side close to the wall, and the outer end of the folded edge is provided with a locking edge portion embedded in the wall.

[0010] The door and window body comprises glass, window sashes and door and window frames. The glass and window sashes are arranged on the door and window frames, and the door and window frames are fixed to the fixing parts on the door and window covers.

[0011] The wall is connected to one or both sides of the door and window frames by casting.

[0012] As a further improvement of the present invention, when the door and window system is installed in a pre-supported mold of a wall with a window, the door and window frames are installed on the walls around the window hole, forming a fully enclosed structure. When the door and window system is installed in a pre-supported mold of a wall with a door, the door and window frames are installed on the wall position except the bottom of the door hole, forming a semi-enclosed structure.

[0013] As a further improvement of the present invention, a plurality of holes are provided around the middle of the door and window frame at intervals, and the width of the holes in the direction parallel to the wall surface tends to decrease from the middle of the door and window frame to both sides of the door and window frame.

[0014] As a further improvement of the present invention, it also includes shaping frames and decorative lines. Several shaping frames are fixedly arranged at the positions half-surrounded by the folded edges on the door and window frames, and integrally cast and fixed in the wall. The decorative lines are fixedly connected to the folded edges or the wall.

[0015] As a further improvement of the present invention, the sealing structure is a folding groove formed by the folding edge being recessed toward a side attached to the wall, and a sealing strip is embedded in the folding groove, and the sealing strip is fitted and sealed with the cast wall side formwork; or an elastic sealing strip is attached to the outer wall of the folding edge, and the elastic sealing strip is fitted and sealed with the wall side formwork; or the outer wall surface of the folding edge and the wall side formwork cast by the wall are both made with flat surfaces, and the flat surfaces of the two are directly fitted and sealed.

[0016] As a further improvement of the present invention, the locking edge structure is a flange formed at the outer end of the folded edge and embedded in the wall; or a thickened protruding structure embedded in the wall is formed at the outer end of the folded edge.

[0017] As a further improvement of the present invention, a pair of vertically folded edges are formed on both sides of the side where the door and window frames are connected to the wall, and the folded edges on both sides are recessed toward the side attached to the wall and are provided with folded edge grooves, and the outer ends of the folded edges on both sides are formed with flanges embedded in the wall; or a vertically folded edge is formed on one side where the door and window frames are connected to the wall, and the folded edge is recessed toward the side attached to the wall and is provided with a folded edge groove, and the outer ends of the folded edge are formed with flanges embedded in the wall.

[0018] As a further improvement of the present invention, the door and window cover comprises an outer window cover and an inner window cover, wherein the outer window cover is arranged on one side of the outer facade of the wall, and the inner window cover is arranged on one side of the inner facade of the wall. The horizontal height of the bottom inner window cover is higher than the horizontal height of the bottom outer window cover.

[0019] As a further improvement of the present invention, a recessed installation groove is formed in the middle of the door and window frame, and a protruding reinforcing rib is formed at the bottom of the door and window frame. The reinforcing rib is matched and embedded in the installation groove and fixed by clamping.

[0020] As a further improvement of the present invention, a method for installing a prefabricated wall and door and window formwork-free combined structure comprises the following steps: a. Pre-assemble the door and window covers and door and window frames into one piece, and install the shaping frames at intervals at the positions half-surrounded by the folded edges on the door and window covers; b. Embed the sealing strip in the folding groove on the folding edge; c. Install and fix the combination of door and window covers and door and window frames at the location of the target door and window openings, and tie the steel reinforcement skeleton of the wall around the combination; d. Install concrete casting templates on both sides of the door and window frames, clamp the templates and the sealing strips in the folding grooves tightly, pour concrete in the templates, and prefabricate the combination of the door and window frames, door and window frames and the forming frame into one body with the wall; e. After the concrete is poured and solidified, install the glass and window sashes in the door and window frames, and fix the finished decorative lines to the folded edges or walls with expansion bolts.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. The door and window covers and door and window frames are pre-assembled and installed, and can be directly cast and fixed during wall construction, and prefabricated into one piece, which saves the time and cost of reserving holes when casting walls in the prior art. When decorating the house, you only need to install the corresponding glass and window sashes in the door and window frames to complete the installation of the entire door and window.

[0022] Second, the door and window frames are cast and fixed to the connected walls, and there is no need for waterproof sealing of the installation gap as in the prior art, which ensures the sealing of the door and window positions and eliminates the complicated gap sealing construction process; and the horizontal height of the bottom inner window frame is higher than the horizontal height of the bottom outer window frame, which has the effect of automatic drainage to the outside and can prevent rainwater from invading from the outer window frame side.

[0023] 3. Holes are opened on the door and window frames to reduce their heat conduction area. Low thermal conductivity cavities are made inside the door and window frames, and the cavity walls are connected with low thermal conductivity connecting materials, which can effectively reduce the heat exchange on both sides of the door and window frames and maintain the stability of the indoor temperature.

[0024] 4. Door and window frames are not only components of the door and window system that need to be installed, but can also serve as templates for the door and window opening walls during the wall casting process, further simplifying the wall construction process.

[0025] 5. Door and window frames serve as decoration and protection for door and window openings, which can improve the aesthetics of the building, protect the life of the house and improve the quality of life of users. BRIEF DESCRIPTION OF THE DRAWINGS
