Description

Technical Field

[0001] This utility model belongs to the technical field of elevator square tube columns, specifically relating to the quick-installation addition of long waisted round hole elevator square tube columns. Background Technology

[0002] With the continuous improvement of living standards, many older residential communities in various cities are gradually installing elevators. The elevator shaft is the first vertical shaft that needs to be installed when adding an elevator. The size of the shaft is determined according to the elevator model. The shaft is generally square in shape, with four vertical columns at its four edges to provide the main support.

[0003] Traditional steel structure shaft columns are generally made of ordinary square tubes. In order to install the shaft side wall beams, perforated plates are welded to the adjacent two side walls of each square tube. The four square tubes and the side beams and side walls of the shaft form the shaft space.

[0004] However, this method of welding perforated plates to the side of the square tube to connect to the side wall of the side beam causes stress concentration at the weld point, making it unstable and prone to cracking. Therefore, the applicant proposes this solution. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this utility model provides a quick-installation elevator square tube column with an elongated oval hole, which directly opens the installation hole on the upright plate of the square tube, so that the stress of the square tube is more dispersed.

[0006] The present invention adopts the following technical solution:

[0007] The elongated, round-hole quick-install elevator square tube column includes four uprights: one, two, three, and four. The four uprights are of equal width and height and surround each other to form a vertical square tube. Mounting holes are provided on uprights one and two, and the mounting holes are arranged at equal intervals along the height direction. The mounting holes have a nut through hole at the top and a narrow, elongated vertical hole at the bottom.

[0008] Preferably, both vertical plate one and vertical plate two have a single row of mounting holes, and the mounting holes on the same layer are at the same height.

[0009] Preferably, two rows of mounting holes are vertically opened on both the first and second vertical plates, and the mounting holes on the same layer are at the same height.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention features mounting holes on a vertical plate of a square tube for connecting to a side beam. The force from the side beam on the square tube is distributed on the vertical plate, making it less prone to cracking. Furthermore, the mounting holes are relatively long vertically, allowing for the installation of side beams with various hole patterns. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings. Throughout the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Unless otherwise specified, the raw materials and equipment used are commercially available or commonly used in the art. The methods in the embodiments, unless otherwise specified, are conventional methods in the art. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] The elongated, round-hole quick-installation elevator square tube column includes four vertical plates: 1, 2, 3, and 4. These four plates are of equal height and width, formed by bending a single sheet of steel three times and welding the joints. The four plates surround each other to form a vertical square tube. A single row of mounting holes 5 is provided on adjacent plates 1 and 2. The mounting holes 5 are equidistant along the height direction, and the mounting holes 5 on the same floor are at the same height. The mounting holes 5 have an upper nut passage hole 51 and a lower, vertically elongated slotted hole 52. The nut passage hole 51 is used to insert the nut end of a bolt, and the slotted hole 52 is used for bolting.

[0020] like Figure 4 The side beam 7 consists of a crossbeam and vertical connecting plates at both ends. The connecting plates have openings corresponding to the mounting holes 5. The lower part of the opening is a round hole, and the upper part is a long hole.

[0021] Elongated, round-hole quick-installation elevator square tube column, when in use:

[0022] like Figure 2 As shown, four square tube columns are located at the four corners of the shaft, and side beams 7 connect adjacent square tube columns. The side beams 7 and the square tube columns are bolted together.

[0023] Example 2

[0024] The difference between this embodiment and embodiment one is that two rows of mounting holes 5 are vertically opened on both the first upright plate 1 and the second upright plate 2. The mounting holes 5 on the same layer are at the same height. This model allows for more bolt connections between the side beams 7 of the column, thus enhancing stability.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to the above embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
