Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled building door, window and wall panel sealing structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., and are representative of modern industrialized production methods because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications.

[0003] For example, the Chinese utility model patent publication number (CN220226590U) discloses a sealed connection structure between assembled building door and window frames and prefabricated wall panels, which includes a prefabricated wall panel, which is a rectangular concrete prefabricated wall, on which a door and window installation position is provided, and a prefabricated door and window frame is provided on the door and window installation position, and the prefabricated door and window frame is a rectangular steel-aluminum alloy frame. This utility model solves the current problem that the prefabricated wall panels and door and window frames mainly rely on foam glue. As well as expansion bolt fixed seal, although this sealing method can achieve sealing during application, the expansion bolts used during installation are large in number and troublesome to operate, inconvenient to install, and the parallel structure used in the sealing part is prone to air leakage. However, in this patent, the door and window auxiliary frames are connected to the prefabricated wall panels by extending threaded rods and connecting sleeves, resulting in a lack of deformation space between the door and window auxiliary frames and the wall panels. When thermal expansion and contraction occur, the door and window auxiliary frames are deformed, which can easily cause the wall panels to rupture, affecting the safety and sealing of the doors and windows. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a sealing structure for doors, windows and wall panels of assembled buildings, which has the advantages of reserving deformation space for door and window auxiliary frames and avoiding cracks between the door and window auxiliary frames and wall panels. It solves the problem that the door and window auxiliary frames and the prefabricated wall panels in the patent are connected by extending threaded rods and connecting sleeves, resulting in a lack of deformation space between the door and window auxiliary frames and the wall panels. When thermal expansion and contraction occur, the deformation of the door and window auxiliary frames can easily cause the wall panels to crack, affecting the safety and sealing of the doors and windows.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled building door, window and wall panel sealing structure, comprising a wall panel body, a mounting opening is provided on the front of the wall panel body, a mounting mechanism for mounting the door and window is provided inside the mounting opening, and a door and window frame is provided inside the mounting opening;

[0006] The mounting mechanism includes two mounting plates, two sealing fillers, two packaging components, and a fixing component. The two mounting plates are respectively fixed to the inner top wall and the inner bottom wall of the mounting opening, and are symmetrically distributed up and down with the central axis of the mounting opening. The two sealing fillers are filled between the opposite sides of the two mounting plates. The two packaging components are respectively arranged on the front and rear sides of the mounting plates for protecting the mounting structure and the sealing structure. The fixing component is arranged on the door and window frame for fixing the door and window frame. A mounting groove is opened between the opposite sides of the two mounting plates.

[0007] The beneficial effect of adopting the above further solution is: maintaining the seal between the doors and windows and the wall panels, while preventing the doors and windows from deforming and causing the wall panels to break.

[0008] Furthermore, the length of the mounting plate is equal to the length of the mounting opening, and the length of the mounting groove is matched to the length of the door and window frame.

[0009] The beneficial effect of adopting the above further solution is: improving the sealing performance of door and window installation.

[0010] Furthermore, the length of the sealing filler matches the distance between opposite sides of the two mounting plates, and the width of the sealing filler matches the width of the mounting plates.

[0011] The beneficial effect of adopting the above further scheme is that the sealing filler still has a certain elasticity after air drying and hardening. When the door and window frames are deformed due to thermal expansion and contraction, the sealing filler leaves a certain deformation space for the door and window frames, thereby preventing the wall panel body from cracking due to the deformation of the door and window frames.

[0012] Furthermore, the packaging component includes a packaging frame, four first fixing bolts, and four first threaded holes. The four first fixing bolts are respectively threadedly connected to the four corners of the packaging frame. The four first threaded holes are grouped in two and are respectively opened on the front sides of two mounting plates. The packaging frame and the mounting plates are fixed by the four first fixing bolts.

[0013] The beneficial effect of adopting the above further solution is to prevent the sealing packing from being affected by the outside world and causing the service life to be reduced.

[0014] Furthermore, the length of the packaging frame is adapted to the length of the installation opening, the width of the packaging frame is adapted to the width of the installation opening, the distance between the left and right inner walls of the packaging frame is adapted to the distance between the left and right inner walls of the door and window frame, and the distance between the upper and lower inner walls of the packaging frame is adapted to the distance between the upper and lower inner walls of the door and window frame.

[0015] The beneficial effect of adopting the above further solution is that the gap between the installation opening and the door and window frame can be completely covered, thereby maintaining the appearance and increasing the service life of the sealing filler.

[0016] Furthermore, the fixing member includes a plurality of connecting holes, a plurality of second threaded holes, and a plurality of second fixing bolts. The plurality of connecting holes are respectively opened on the inner bottom wall and the inner top wall of the door and window frame and are equidistantly distributed. The plurality of second threaded holes are respectively opened on the inner top wall of the upper mounting groove and the inner bottom wall of the lower mounting groove, and the positions of the second threaded holes correspond one-to-one to the positions of the connecting holes. The plurality of second fixing bolts are respectively connected to the inner threads of the plurality of second threaded holes.

[0017] The beneficial effect of adopting the above further solution is: improving the stability of the door and window frames.

[0018] Furthermore, the inner diameter of the connecting hole is larger than the outer diameter of the second fixing bolt, and the inner diameter of the connecting hole is smaller than the width of the top end of the second fixing bolt.

[0019] The beneficial effect of adopting the above further solution is: preventing the second fixing bolt from falling out of the connecting hole, so that the second fixing bolt can fix the door and window frame and the mounting plate when being threadedly connected with the second threaded hole.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] 1. The sealing structure of prefabricated building doors, windows and wall panels can facilitate the positioning of the door and window frames through the cooperation of the mounting plate and the mounting groove, thereby improving the installation efficiency of the door and window frames. Through the cooperation of the sealing filler, the gap between the door and window frame and the mounting opening can be blocked, thereby improving the sealing between the door and window and the wall panels, preventing indoor air leakage and water leakage, etc. At the same time, the sealing filler has a certain elasticity and can provide deformation space for the door and window frames.

[0022] 2. The sealing structure of the assembled building doors, windows and wall panels can fix the door and window frames in the installation grooves through the cooperation of the second threaded holes and the second fixing bolts, thereby improving the stability of the door and window frame installation. Through the cooperation of the packaging frame, the installation openings and sealing fillers can be shielded and protected, thereby avoiding a reduction in the service life of the sealing fillers, and it is also very convenient to add sealing fillers.
