Description

Technical Field

[0001] This utility model relates to the field of construction mold technology, specifically to a dormer window forming mold. Background Technology

[0002] A dormer window is a type of roof window design. As an independent window structure projecting from a sloping roof, it achieves efficient lighting and ventilation in the attic space through components such as the roof slab and facade walls, while also serving to expand space and decorative functions. It is typically divided into two types: gable and eaves. In modern times, it is widely used in villas, loft renovations, and the preservation of historical buildings. Its core advantage lies in the combination of excellent lighting and ventilation with European aesthetics.

[0003] During the manufacturing process of dormer windows, they are mostly constructed by cast-in-place construction. Cast-in-place construction requires on-site formwork, pouring, and curing, which takes a long time and is greatly affected by the weather. In addition, the operation of assembling and disassembling formwork at heights is not very safe. Utility Model Content

[0004] The purpose of this utility model is to provide a dormer window forming mold to solve the problems of long construction period and great influence of weather in the existing technology of cast-in-place construction.

A plate seat is fixedly installed on the top of the inclined support leg, and a threaded rod is threadedly connected to the inner wall of the plate seat. A connecting plate is rotatably connected to the end of the threaded rod.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a dormer window forming mold, comprising:

[0024] Supporting base 1;

[0025] Prefabrication mechanism 2 is set on top of the receiving base 1 and is used to prefabricate the dormer window frame;

[0026] External vibration mechanism 3 is installed on the receiving base 1 and is used to vibrate the concrete from the outside.

[0027] The prefabrication mechanism 2 includes a vertical support leg 21, which is fixedly installed on the top of the support base 1. A fixed mold 22 is fixedly installed on the top of the vertical support leg 21. A forming cavity 23 is provided on the fixed mold 22. Movable templates 24 are movably attached to both sides of the fixed mold 22. A protrusion 25 located inside the forming cavity 23 is fixedly connected to the side of the movable template 24. Through the cooperation of the fixed mold 22 and the movable template 24, the user can fill the inside of the forming cavity 23 with steel bars and concrete to prefabricate the dormer window frame, reduce on-site construction errors, avoid weather interference with the construction of the dormer window frame, and avoid the safety problems caused by assembling and disassembling templates at high altitudes. Lifting lugs are also added and tied to the steel bars for easy subsequent handling.

[0028] As one implementation method in this embodiment, such as Figure 2 As shown, the prefabrication mechanism 2 also includes an inclined support leg 26, which is fixedly installed on the top of the receiving base 1. A plate seat 27 is fixedly installed on the top of the inclined support leg 26. A threaded rod 28 is threadedly connected to the inner wall of the plate seat 27. A connecting plate 29 is rotatably connected to the end of the threaded rod 28. After molding, by rotating the threaded rod 28, the movable template 24 can be removed from the side of the fixed mold 22, which facilitates the removal of the dormer window frame.

[0029] As one implementation method in this embodiment, such as Figure 2 As shown, the movable template 24 is detachably connected to the side of the connecting plate 29. A limiting rod 291 is fixedly installed on the outer wall of the connecting plate 29. The limiting rod 291 is slidably connected to the inner wall of the plate base 27. The limiting rod 291 is used to guide the movement of the movable template 24. Through the design of the protrusion 25, a pattern can be formed on the side of the dormer window frame to improve the aesthetics. The movable template 24 is installed on the connecting plate 29 with bolts. Users can replace the movable template 24 with different shaped protrusions 25 to create different patterns to meet customer needs.

[0030] As one implementation method in this embodiment, such as Figure 3 As shown, the external vibration mechanism 3 includes a raised platform 31, which is fixedly installed on the top of the receiving base 1. An external vibrator 35 is fixedly installed on the top of the raised platform 31. After the concrete is filled into the interior of the molding cavity 23, the external vibrator 35 is controlled to work, which can drive the prefabrication mechanism 2 to vibrate as a whole to remove air bubbles inside the concrete and improve the quality of the dormer window frame. The external vibrator 35 is an existing device, which is an electric motor with a vibration function.

[0031] As one implementation method in this embodiment, such as Figure 3 As shown, a limiting block 32 is fixedly installed on the top of the protrusion 31. A protective frame 33 is movably inserted into the inner side of the limiting block 32. A ventilation groove is provided on the outer wall of the protective frame 33. A breathable net 34 is fixedly installed on the inner wall of the ventilation groove. The protective frame 33 is used to wrap and protect the external vibrator 35 to prevent collision damage from objects such as gravel and steel bars. The design of the ventilation groove is conducive to heat dissipation of the external vibrator 35. The design of the breathable net 34 can block dust and further increase the safety of the external vibrator 35.

[0032] As one implementation method in this embodiment, such as Figure 4As shown, the external vibrating mechanism 3 also includes a base 36 and a square frame 363. An elastic element 361 is fixedly installed on the top of the base 36, and the top of the elastic element 361 is fixedly connected to the bottom of the receiving base 1. A square column 362 is fixedly installed on the top of the base 36, and the square frame 363 is fixedly installed on the top of the receiving base 1. A locking bolt 364 is threadedly connected to the square frame 363. The threaded end of the locking bolt 364 is in movable contact with the outer wall of the square column 362. By rotating the locking bolt 364, its threaded end is moved away from the outer wall of the square column 362. At this time, the base 36 and the receiving base 1 are only elastically supported by the elastic element 361, which can improve the effect of the external vibrator 35 driving the prefabrication mechanism 2 to vibrate as a whole. When performing maintenance operations on the prefabrication mechanism 2, the locking bolt 364 can be tightened so that its end is tightly attached to the outer wall of the square column 362, so that the receiving base 1 and the base 36 are firmly connected, reducing the impact on the user's operation.

[0033] Working principle: During use, steel bars and concrete are filled into the molding cavity 23, and lifting lugs are added and tied to the steel bars. After the concrete is filled into the molding cavity 23, the external vibrator 35 is controlled to work, which can drive the prefabrication mechanism 2 to vibrate as a whole to remove air bubbles inside the concrete. After the dormer window frame is formed, the movable template 24 can be removed from the side of the fixed mold 22 by rotating the threaded rod 28, and then the dormer window frame can be taken out for use.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
