Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly to an arched door opening support device. Background Art

[0002] Arched door openings are quite popular in interior building decoration. An arc surface is provided at the upper end of a conventional rectangular door opening to increase the aesthetic degree. Arched door openings include circular arches and flat arches. A circular arch is formed by setting the upper horizontal part of a rectangular door opening as an arc, i.e., a semi-circle, and a flat arch is formed by retaining a part of the upper horizontal part of a conventional rectangular door opening and building a fillet structure with an arc surface at two right angles. The support structure and its construction of a flat arch door opening are roughly divided into two methods. One is to build a keel with an arc surface at two right angles at the upper end of a rectangular door opening and fix it to the wall through fasteners, then cover a gypsum board at the support structure, i.e., the keel, and finally decorate it together with the wall to form an integral transition with the wall. The other is to directly paste prefabricated parts. Prepare prefabricated parts made of materials such as foam and gypsum in advance, fix the prefabricated parts to two right angles of the rectangular door opening through an adhesive, and finally decorate it together with the wall.

[0003] However, when installing an arched door opening support device, there may be a situation where the height of the door opening needs to be changed. For example, the distance between the indoor ceiling and the highest point of the door opening is relatively close, or the owner needs to keep the heights of all indoor door openings the same. In this case, the height of the door opening will be reduced. First, calculate the height that needs to be reduced and mark it at the door opening, then make a support member to act as the highest point of the door opening, such as a wooden board or a steel plate, and then build the support member at the marked position and install it on the wall through fasteners. Finally, build a fillet structure at the support member according to the above steps. However, the above steps are relatively cumbersome and troublesome to construct. Summary of the Utility Model
