Description

Technical Field

[0001] This utility model specifically relates to a prefabricated elevator entrance door frame, belonging to the field of elevator door frame technology. Background Technology

[0002] Elevators, as an important mode of vertical transportation in building interiors, solve the problem of personnel flow between floors and are also an important functional area of ​​public space. In decoration design, the elevator frame is usually decorated with a door frame. Stainless steel door frames are generally used to finish the junction between the elevator frame and the wall material. First, a wooden plywood base is made at the elevator door opening. The stainless steel door frame is cut according to the site dimensions. A gap is left between the stainless steel door frame and the elevator door opening. Foam glue is injected into the gap to fix the stainless steel door frame to the elevator door opening. During the curing process of the foam glue at the corner of the stainless steel door frame connection, it is easy to shift and deform under stress. At the same time, after the foam glue has solidified, the stainless steel door frame can only be removed by breaking it, which cannot meet the requirements of the development of prefabricated decoration technology.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-7 As shown, Figures 1-7 The illustration schematically shows a prefabricated elevator entrance door frame according to the present invention.

[0017] An assembled elevator entrance door frame includes an elevator door opening 1 and an elevator door frame 2. The feature is that it also includes a door frame 3, a sliding groove 7 and a sliding rail 8. The sliding groove 7 and the sliding rail 8 are arranged sequentially between the door frame 3 and the elevator door opening 1. The sliding groove 7 is provided with a slot 7.1, and the sliding rail 8 is provided with a rail 8.1. The slot 7.1 is connected to the sliding groove 7 through the rail 8.1. The door frame 3 includes a left door frame 3.1, a right door frame 3.2, and an upper door frame 3.3. The left door frame 3.1 includes a folded edge 3.11, a double folded edge 3.12, and an inner cavity 3.13 located between the folded edge 3.11 and the double folded edge 3.12. The folded edge 3.11 is connected to the elevator door frame 2, and the double folded edge 3.12 is fixed to the stone 4 for finishing the stone 4. The lower section of the inner cavity 3.13 is provided with a backing plate 3.16 for fixing the slide groove 7.

[0018] Among them, the backing plate 3.16 uses extruded polystyrene board core material. Extruded polystyrene board core material has the characteristics of being lightweight, high-strength and pressure-resistant, which enhances the overall rigidity of the left door frame 3.1 and facilitates the fixing of the slide groove 7.1.

[0019] Among them, the groove 7.1 allows the slide rail 8 to be connected to the slide groove 7 through the rail 8.1, so as to realize the prefabricated installation of the left door frame 3.1 and the right door frame 3.2. This solves the problem that after the foam glue solidifies, the stainless steel door frame needs to be disassembled and adjusted, which can only be removed by breaking it, and cannot meet the requirements of the development of prefabricated decoration technology.

[0020] Furthermore, the upper door frame 3.3 is located between the left door frame 3.1 and the right door frame 3.2, and the upper door frame 3.3 is provided with a flat pin 3.31 and a vertical pin 3.32 on both sides.

[0021] Furthermore, the inner cavity 3.13 is provided with a flat hole 3.14 and a vertical hole 3.15.

[0022] Furthermore, the flat pin 3.31 is inserted into the flat hole 3.14, and the vertical pin 3.32 is inserted into the vertical hole 3.15.

[0023] Furthermore, a square hole 3.33 is provided in the middle of the upper door frame 3.3.

[0024] Furthermore, the right door frame 3.2 and the left door frame 3.1 are symmetrically distributed.

[0025] The cross-sections of the right door frame 3.2 and the left door frame 3.1 are both C-shaped and have the same structural features. The structure of the right door frame 3.2 will not be described in detail here.

[0026] Furthermore, the flat pin 3.31 and the vertical pin 3.32 are provided with folding pieces 3.311.

[0027] Among them, the flap 3.311 can be bent. After the flap 3.311 is bent into place, it is used to restrict and fix the left and right door frames and the flat hole 3.14 and the vertical hole 3.15 to prevent displacement and deformation.

[0028] Furthermore, it also includes a base plate 6, to which the slide rail 8 is connected by screws 5 for adjusting the level of the elevator door opening 1.

[0029] The beneficial effects of this utility model are: This utility model utilizes the connection between the sliding groove and the sliding rail to achieve the assembly installation of the left and right door frames. This solves the problem that the door frames can only be removed by breaking them after the traditional foam adhesive has solidified. Furthermore, it adds bendable tabs to the flat pins and vertical pins to physically fix the flat and vertical holes, thus solving the problem of door frames being prone to displacement and deformation due to stress.

[0030] Installation steps of this utility model: Step 1: Install the base plate 6 around the elevator door frame 2. Use the base plate to calibrate the elevator door opening 1 horizontally and vertically to ensure that the installation reference surface is flat. Step 2: Fix the slide rail 8 to the base plate 6 using screws 5 to form a continuous guide rail system for subsequent sliding installation of the door frame. Check the position, straightness, and height consistency of the slide rails to ensure symmetrical matching of the left and right slide rails 8; Step 3: Place the left door frame 3.1 and right door frame 3.2 symmetrically according to the design position, ready to connect with the upper door frame. Install the upper door frame 3.3: Align the flat pins 3.31 and vertical pins 3.32 at both ends of the L-shaped upper door frame with the flat holes 3.14 and vertical holes 3.15 on the left door frame, and the corresponding holes on the right door frame 3.2, respectively. Lock the connection: Bend the flexible tabs 3.311 on the flat pins and vertical pins into place to achieve mechanical locking, so that the left, right, and upper door frames form a stable whole door frame structure; Step 4: Aligning the Slide 7 with the Track 8. Push the assembled door frame into the installation position from above or side. Align the slide 7 on the inner side of the left door frame 3.1 and the right door frame 3.2 with the track 8 already installed on the base plate, with the track 8.1 inserted into the groove 7.1 of the slide. Slide the door frame 3 along the track direction to the final positioning position, ensuring that the door frame 3 is aligned with the elevator door opening 1 and the gap is uniform. Check the overall verticality and horizontality of the door frame 3 and the finishing of the joint with the wall decorative stone 4.
