Technical Field

[0001] The present invention belongs to the technical field of elevator column installation, and particularly relates to a long-hole column of square pipe in a steel structure hoistway for elevator installation. Background Art

[0002] With the continuous improvement of living standards, the work of installing elevators in some old communities in each city is being carried out successively. The elevator shaft is a vertical shaft that needs to be arranged first when installing an elevator. The size of the shaft is determined according to the elevator type selection. The planar shape of the shaft is generally square, and there are four vertical columns providing the main supporting force at the four edges of the shaft.

[0003] The columns of traditional steel structure hoistways are generally ordinary square pipes. In order to install the crossbeams on the side walls of the hoistway, perforated plates are welded to the adjacent two side walls of each square pipe. The four square pipes and the four side walls surround to form a hoistway space. The four vertical edges of the hoistway space are usually the inner edges of the four square pipes, and the relative area of the square pipe and the inner space of the hoistway is large.

[0004] In order to further optimize the floor area ratio of the square pipe and the hoistway space, the applicant designs and proposes this column. Summary of the Invention

[0005] To overcome the above technical problems, the present invention provides a long-hole column of square pipe in a steel structure hoistway for elevator installation.

[0006] The present invention adopts the following technical solutions: A long-hole column of square pipe in a steel structure hoistway for elevator installation, including a first vertical plate, a second vertical plate, a third vertical plate, a fourth vertical plate, a fifth vertical plate, and a sixth vertical plate. The six vertical plates are sequentially connected end to end to form a right-angle hollow column. The fifth vertical plate and the sixth vertical plate are recessed into the column and perpendicular to each other. The fifth vertical plate is perpendicular to the fourth vertical plate, and the sixth vertical plate is perpendicular to the first vertical plate. The fifth vertical plate and the sixth vertical plate are vertically and arrayedly provided with installation holes. The top ends of the installation holes are widened to form nut passing holes. The vertical length of the installation holes is more than twice the horizontal width.

[0007] Preferably, the second vertical plate and the third vertical plate have the same width, and the first vertical plate, the fourth vertical plate, the fifth vertical plate, and the sixth vertical plate have the same width.

[0008] Preferably, a pair of vertical convex strips are provided on the inner wall of the fifth vertical plate. The two convex strips are respectively located on both sides of the installation hole, and the distance between the two convex strips is between the hole width of the installation hole and the diameter of the nut passing hole.

[0009] Preferably, two convex strips are similarly provided on the inner wall of the sixth vertical plate.

[0010] Preferably, the inner side edges of the two convex strips are bent towards each other to form folded edges, and the opposite edges of the two folded edges do not block the installation holes.

[0011] Preferably, on the inner walls of the fifth vertical plate and the sixth vertical plate, bumps are provided between two adjacent mounting holes.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: On the basis of the traditional square tube column, the present invention forms the fifth vertical plate and the sixth vertical plate by inward folding, which strengthens the strength. The fifth vertical plate and the sixth vertical plate are bolted to the cross beam on the side wall of the shaft, without the need for on-site welding of the column, which is convenient and stable to use. Moreover, the inward folding design reduces the floor area of the column, while increasing the corresponding area of the space inside the shaft. In addition, the mounting holes are vertically long, which can accommodate cross beams with various types of openings; The present invention provides rib strips on the inner walls of the fifth vertical plate and the sixth vertical plate, which can assist in stabilizing the nut inside and prevent the nut from rotating with the screw, facilitating the bolt installation work; On the basis of the rib strips, the present invention provides a hem, which further stabilizes the nut and restricts the axial movement of the nut, facilitating the installation of the bolt; On the basis of the hem, the present invention further provides bumps. The bumps cooperate with the rib strips and the hem to prevent the nut from rotating, axially moving, and falling downward inside the column. BRIEF DESCRIPTION OF THE DRAWINGS
