Description

Technical Field

[0001] This utility model relates to a standardized groove forming structure for exterior doors and windows, belonging to the field of building tool technology. Background Technology

[0002] In existing technologies, the window edges of doors and windows are often treated with foaming agents and waterproof mortar, and then cement mortar is used to finish the edges. This construction method requires high skill from the workers. If any of the three steps of foaming agent application, waterproof mortar sealing, or plastering is neglected, water seepage can easily occur at the window edges.

[0003] Specifically, the existing technology has the following problems: 1. Multiple construction steps are involved, resulting in a long construction time and compromised construction quality. (For example, if the wall plastering is done first and then the joints are filled, cracks in the plaster layer will tear the joint filler.) 2. Existing technology makes it difficult to ensure a slope that is lower on the outside and higher on the inside for window frame structures, which can easily lead to rainwater backflow.

[0004] 3. The gaps between the door and window edges and the outer edges of the doors and windows are difficult to seal effectively, which can easily lead to cold gaps and leakage. Utility Model Content

[0005] This utility model proposes a standardized groove forming structure for exterior doors and windows, which aims to overcome the above-mentioned shortcomings of the existing technology, realize one-time forming of grooves on the edges of exterior doors and windows, facilitate the finishing of window edge plastering, and reduce the risk of leakage.

[0006] The technical solution of this utility model is a standardized grooved molding structure for exterior doors and windows. It uses PVC-U pressing sheets, which are precisely laid out and fixed to the inside of the window edge template using self-tapping screws before the template is closed. After the concrete is poured, the sheet is removed along with the template, creating a water-blocking tongue-and-groove joint on the inside of the window. Compared to existing technologies, this eliminates the need for finishing the inside of the window and allows the mortar at the bottom of the window to directly seal the inside of the tongue-and-groove joint, flush with the edge, effectively reducing the risk of leakage around the window.

[0007] Specifically, its structure includes four pressure plates, namely an upper pressure plate, a lower pressure plate, and two side pressure plates. All four pressure plates are long pieces with an isosceles trapezoidal cross-section. The upper pressure plate, the lower pressure plate, and the two side pressure plates are respectively fixed to the four outer surfaces of the window opening perimeter template. The lower base of the isosceles trapezoidal cross-section of the four pressure plates is in contact with the corresponding outer surface of the window opening perimeter template, and the straight waist of the isosceles trapezoidal cross-section of the four pressure plates is flush with the outer surface of the window opening.

[0008] Preferably, the compressed sheet is a PVC-U compressed sheet.

[0009] Preferably, the angle between the sloping leg and the lower base of the isosceles trapezoid is 45°.

[0010] Preferably, a plurality of screw holes for fixing with self-tapping screws are evenly spaced along the length of the pressing sheet, and the pressing sheet is fixed to the template around the window opening by self-tapping screws passing through the screw holes.

[0011] Preferably, the pressure plate is provided with guide holes near both ends, and the outer side of the template around the window opening is provided with window frame installation positioning lines corresponding to the positions of the guide holes.

[0012] The advantages of this utility model are: Its reasonable structural design allows for one-time molding of door and window edge grooves, avoiding the defects of multiple processes in existing technologies. This ensures a stable, waterproof tongue-and-groove joint at the junction of the door / window frame and the wall, effectively reducing the risk of window leakage and improving the reliability of building construction quality. Specifically: 1. Improved process simplification: It can form a concrete tongue and groove joint, replacing the existing plastering finishing process, reducing manual operation steps and effectively improving the construction efficiency of door and window edge finishing.

[0013] 2. Enhanced waterproof reliability: The tongue and groove structure forms a slope that is lower on the outside and higher on the inside, which can effectively guide condensation and prevent capillary penetration.

[0014] 3. Standardized Quality Control: The dimensional accuracy of the groove can be guaranteed by the mold, eliminating human error. Standardized curing can be achieved with matching tongue-and-groove cleaning tools, ensuring excellent adhesion strength of the subsequent waterproof layer. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0020] like Figure 1-3As shown, a standardized pressure groove forming structure for exterior doors and windows includes four pressure plates: an upper pressure plate 1, a lower pressure plate 2, and two side pressure plates 3. Each pressure plate is an isosceles trapezoidal long piece with a 45° angle between the sloping side and the lower base. The pressure plates are injection molded from rigid PVC-U material. The upper pressure plate 1, lower pressure plate 2, and two side pressure plates 3 are respectively fixed to the four outer surfaces of the window opening perimeter template 4. The lower base of the isosceles trapezoidal cross section of the four pressure plates is attached to the corresponding outer surface of the window opening perimeter template 4. The straight side of the isosceles trapezoidal cross section of the four pressure plates is flush with the outdoor plane of the window opening 7 (i.e., the straight side of the isosceles trapezoidal cross section of each pressure plate is flush with the outdoor side of the window sill 9 and the outdoor side of the beam 8).

[0021] When fixing, several screw holes for fixing self-tapping screws 6 are evenly spaced along the length of the pressure plate. The pressure plate is fixed to the window opening perimeter template 4 by the self-tapping screws 6 passing through the screw holes. Guide holes 5 are provided near both ends of the pressure plate. Window frame installation positioning lines corresponding to the positions of the guide holes 5 are provided on the outer side of the window opening perimeter template 4.

[0022] Based on the above structure, during operation, after marking the lines on the inner side of the formwork 4 around the window opening 7 (or door opening), each pressure plate is anchored to the formwork 4 around the window opening using self-tapping screws 6, with the screw heads of the self-tapping screws 6 sinking into the bottom of each pressure plate. During concrete pouring, this groove forming structure guides the concrete to form a tongue and groove profile, forming a groove after demolding, which directly serves as the reference surface for the waterproof layer construction. Example

[0023] The sheet is 100mm wide and 20mm thick. (Width and thickness can be adjusted depending on the finishing finish and window frame construction.) The self-tapping screw 6 is an M8×80mm self-tapping screw, arranged at a spacing of ≤300mm. It is recommended to use matching plastic washers to prevent thread damage during concrete pouring.

[0024] The guide hole is 5Φ5mm, which is precisely matched with the window frame installation positioning line, ensuring that the deviation between the center line of the pressure groove and the outer edge of the window frame is less than 2mm.

[0025] During concrete pouring, this groove forming structure guides the concrete to form a tongue and groove profile. After demolding, the resulting groove is 100mm wide and 20mm deep.

[0026] Compared with existing technologies, it has the following specific differences and advantages:

[0027] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
