[0028] The exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present disclosure, and are not intended to exhaust all possible ways of the present disclosure, nor to limit the scope of the present disclosure.

[0029] like Figure 1 and Figure 2 As shown, the present disclosure provides a bottom elevator door frame, specifically, including a high-head type bottom elevator door frame and a common type bottom elevator door frame. The elevator door frame includes an upper decorative part 2 installed above the elevator door opening and two side decorative parts 1 installed on two sides of the elevator door opening. The upper decorative part 2 of the high-head type bottom elevator door frame has a higher height than the upper decorative part 2 of the common type bottom elevator door frame.

[0030] Each side decoration part 1 may include an inner side decoration part installed on the inner wall surface of the elevator door opening (perpendicular to the elevator door) and an outer side decoration part installed on the outer wall surface of the elevator door opening (parallel to the elevator door), and the substrate 11 of the inner side decoration part and the substrate 11 of the outer side decoration part may be formed separately and connected by an angle connector. The base plate 12 of the inner side decoration part and the base plate 12 of the outer side decoration part may be formed in one piece, for example, by bending the plate.

[0031] like Figure 3 and Figure 4 As shown, the side decorative part 1 includes a laminated substrate 11, a base plate 12 and a decorative plate 13. The substrate 11 includes a fireproof board, and the base plate 12 includes a metal plate, such as a stainless steel plate. The decorative plate 13 is used to provide the appearance of the elevator door frame. The base plate 12 is located between the substrate 11 and the decorative plate 13. The substrate 11, the base plate 12 and the decorative plate 13 are combined into a whole to form the side decorative part 1.

[0032] Figure 5 and Figure 6 This is an oblique stereoscopic view of the top of the elevator door frame. Figure 5 and Figure 6 As shown, the bottom plate 12 of the side decorative part 1 can be bonded to the substrate 11 and extend from the substrate 11, for example, the side decorative part 1 is located as a whole on the side of the upper decorative part 2. The bottom plate 12 of the outer side decorative part of the side decorative part 1 extends toward the elevator door opening along the depth direction D of the elevator door frame on the side of the substrate 11, so that the bottom plate 12 can be connected to the upper decorative part 2 (the outer upper decorative part of the upper decorative part 2) by screwing the screw 3 of the upper decorative part 2 along the width direction W of the elevator door frame.

[0033] In another embodiment not shown, the side decorative portion 1 can be located as a whole below the upper decorative portion 2, and the base plate 12 extends above the substrate 11 in the depth direction of the elevator door frame, so that the base plate 12 can be connected to the upper decorative portion 2 by means of a screw connector 3 that is screwed into the upper decorative portion 2 in the height direction of the elevator door frame.

[0034] You can install the elevator door cover by following the steps below:

[0035] First, the substrate 11 and the base plate 12 are combined into a whole to form a transition body of the side decorative part 1, and for example, the substrate 11 and the decorative plate 13 of the upper decorative part 2 are combined to form the upper decorative part 2. This can be completed before the elevator door frame leaves the factory, so that the transition body and the decorative plate 13 of the side decorative part 1, and the upper decorative part 2 are transported separately to the installation site.

[0036] Then, at the installation site, the transition body of the side decorative part 1 is assembled with the upper decorative part 2, for example, Figure 5 and Figure 6 As shown, the base plate 12 of the side decorative part 1 can be connected to the upper decorative part 2 via the screw connector 3. In order to improve the connection reliability, the inner side decorative part of the side decorative part 1 can also be screwed to the inner upper decorative part of the upper decorative part 2 via the screw connector.

[0037] Then, the transition body and the upper decorative part 2 are assembled as a whole and installed in the elevator door opening, for example, the expansion bolts 4 are inserted into the base plate 12 and screwed into the wall.

[0038] Finally, the decorative panel 13 of the side decorative portion 1 is mounted on the transition body, for example, the decorative panel 13 is bonded to the transition body.

[0039] In this way, the transition body including the base plate 12 and the base material 11 can be installed to the elevator door opening before the decorative panel 13, so as to ensure that the elevator door frame can function. For example, the elevator can be installed and used normally. At the same time, the decorative panel 13 can be installed after the building decoration is completed. The decorative panel 13 is protected and will not be damaged during the building decoration process.

[0040] The base material 11 is easily affected by moisture and becomes damp and then deformed. The base plate 12 is combined with the surface of the base material 11, for example, bonded to the base material 11, so as to avoid deformation of the base material 11 and ensure that the transition body functions normally. The integrated base plate 12 has strong integrity, which can reduce possible deformation of the base material 11, and especially ensure that the separate base material 11 of the side decorative part 1 functions normally.

[0041] The base plate 12 is screwed to the upper decorative part 2 through the screw connector 3. In this way, the base plate 12 not only protects the substrate 11, but also serves to connect the upper decorative part 2. It has multiple uses, simplifies the structure of the elevator door frame, and reduces the manufacturing cost of the elevator door frame.

[0042] The upper decorative part 2 has a lower risk of being damaged due to its higher position. Considering the manufacturing cost and installation process, the upper decorative part 2 may include the substrate 11 and the decorative plate 13 but not the base plate 12 .

[0043] like Figure 3 and Figure 4 As shown, the base plate 12 of the side decorative part 1 is connected to the inner wall of the elevator door opening through the expansion bolt 4. Specifically, the expansion bolt 4 is sleeved with a transition piece, and the transition piece is screwed to the base plate 12, so that when the expansion bolt 4 is screwed into the wall, the transition body is installed on the wall. The decorative plate 13 covers the surface of the base plate 12 to shield the expansion bolt 4, which plays a role in beautifying the appearance of the elevator door frame.

[0044] The base material 11 including the fireproof board has good fireproof performance, and there is no need to apply additional fireproof paint or reduce the use of fireproof paint, which has the advantage of simplifying the process.

[0045] It should be understood that the above embodiments are merely exemplary and are not intended to limit the present disclosure. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present disclosure without departing from the scope of the present disclosure.
