Description

Technical Field

[0001] The invention belongs to the technical field of elevator square tube columns, and particularly relates to an elevator square tube column with a long waist and round holes for quick installation. Background Art

[0002] With the continuous improvement of living standards, some older residential communities in various cities are gradually installing elevators in their buildings. The elevator shaft is the first vertical shaft that needs to be arranged when installing an elevator. The size of the shaft is determined by the selected elevator model. The plane shape of the shaft is generally square, with four vertical columns at the four corners providing the main support force.

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

[0004] However, this method of welding perforated plates on the sides of the square tubes to connect the side beam sidewalls will cause the stress of the square tubes to be concentrated at the welding position with the perforated plates, which is not stable and easily leads to cracking. Based on this, the applicant designed and proposed this solution. Summary of the Invention

[0005] In order to overcome the above technical problems, the present invention provides a long waist round hole quick installation elevator square tube column, and directly opens the installation hole on the vertical plate of the square tube, so that the stress of the square tube is more dispersed.

[0006] The present invention adopts the following technical solutions: The long waist round hole quick-install elevator square tube column includes vertical plate one, vertical plate two, vertical plate three and vertical plate four. The four vertical plates are surrounded to form a vertical square tube. Mounting holes are opened on vertical plate one and vertical plate two, and the mounting holes are arranged equidistantly along the height direction; the mounting hole has a nut through hole at the top and a vertical narrow waist hole at the bottom.

[0007] Preferably, a single row of mounting holes are vertically provided on both the vertical plate 1 and the vertical plate 2, and the mounting holes on the same layer are at the same height.

[0008] Preferably, two rows of mounting holes are vertically provided on both the vertical plate 1 and the vertical plate 2, and the mounting holes on the same layer are at the same height.

[0009] Preferably, vertical plate one, vertical plate two, vertical plate three and vertical plate four are of equal height and width.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The present invention opens a mounting hole for connecting with the side beam on the vertical plate based on the square tube. The square tube can disperse the force from the side beam on the vertical plate and is not prone to cracking. In addition, the mounting hole is vertically longer and can adapt to the installation of side beams of various models and opening styles. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings. The same or similar reference numerals throughout represent 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0014] The long waist round hole quick-install elevator square tube column includes vertical plate 1, vertical plate 2, vertical plate 3 and vertical plate 4. The four vertical plates are of equal height and width and are formed by bending a whole steel plate in three passes. The seams are welded. The four vertical plates are surrounded to form a vertical square tube. A single row of mounting holes 5 are opened on the adjacent vertical plates 1 and 2. The mounting holes 5 are arranged equidistantly in the height direction, and the mounting holes 5 on the same layer are of the same height; the mounting hole 5 has an upper nut through hole 51 and a lower vertical narrow waist hole 52. The nut through hole 51 is used to place the nut end of the bolt, and the waist hole 52 is partially used for bolting.

[0015] like Figure 4 The side beam 7 is composed of a crossbeam and vertical connecting plates at both ends. The connecting plates are provided with openings corresponding to the mounting holes 5. The lower section of the opening is a circular hole, and the upper section is a long hole.

[0016] Long waist round hole quick installation elevator square tube column, when using: like Figure 2 As shown, four square tube columns are located at the four corners of the shaft, side beams 7 connect adjacent square tube columns, and the side beams 7 and the square tube columns are bolted together.

[0017] Example 2 The difference between this embodiment and the first embodiment is that two rows of mounting holes 5 are vertically provided on both the first vertical plate 1 and the second vertical plate 2, and the mounting holes 5 on the same layer are at the same height. This model allows more bolt connections between the column side beams 7 to enhance stability.

[0018] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the above embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
