Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, in particular to an elevator steel structure hoistway column. Background Art

[0002] At present, the shaft column in the steel structure elevator shaft serves as the main shaft frame and mainly plays a load-bearing role. During the installation of the elevator shaft, the installation of the shaft column is particularly important. The existing shaft is usually supported by four columns arranged along the height direction. The columns are relatively long as a whole, and each column is usually welded by multiple shorter columns. However, the welding connection method not only requires construction workers to have high welding technology, but also has high operation difficulty and is time-consuming and labor-intensive.

[0003] Moreover, some old residential buildings with more than four floors or outdoor areas need to be equipped with elevators. Such elevators are usually used outdoors and need to withstand the test of rain, which requires high anti-corrosion. The existing elevator shaft columns often use square tubes, H-steel, and angle steel. Square tubes are difficult to spray for anti-corrosion on the inside and have low bending strength. H-steel and angle steel have poor torsional resistance.

[0004] Therefore, it is urgent to develop an elevator steel structure shaft column that is easy to install, has good anti-corrosion effect, good bending strength and torsional strength performance. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an elevator steel structure shaft column, which is connected by two rivet holes and strip bolt holes staggered up and down on the front wall plate and the rear wall plate. The riveted part extends out of the rectangular column and is fixed by hydraulic riveting. The surface is first sprayed with an anti-corrosion layer on both the inside and outside and then installed, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator steel structure shaft column, comprising a front wall plate and a rear wall plate, the front wall plate comprising two mutually perpendicularly connected front wall side plates and a bending portion arranged on one side of the front wall side plates, the rear wall plate comprising two mutually perpendicularly connected rear wall side plates and a third bending edge arranged on one side of the rear wall side plates;

[0007] The bending portion includes a first bending edge and a second bending edge, the first bending edge is bent inward relative to the front wall side plate and is perpendicular to the front wall side plate, and the second bending edge is bent outward relative to the front wall side plate and is perpendicular to the first bending edge;

[0008] The third bent edge is bent outward relative to the rear wall side plate and is perpendicular to the rear wall side plate;

[0009] The second bending edge and the third bending edge are both provided with a plurality of strip bolt holes and a plurality of rivet holes that match each other in sequence, the rivet holes are provided with rivets, and the second bending edge and the third bending edge are fixedly connected by the rivets;

The front wall plate and the rear wall plate are connected by staggering two strip bolt holes and rivet holes, which has better strength; the front wall plate and the rear wall plate are fixed by inserting rivets in the rivet holes and adopting hydraulic riveting; the riveted part extends outside the rectangular column, so that the torsional strength and bending resistance of the overall structure are greatly enhanced; the upper and lower columns are connected by electric welding to strengthen the connection, so that the overall structure is torsion-resistant and bending-resistant.

[0012] Furthermore, the cross-sectional side length of the front wall plate accounts for 3 / 4 of the cross-sectional side length of the square frame structure, and the cross-sectional side length of the rear wall plate accounts for 1 / 4 of the cross-sectional side length of the square frame structure.

[0013] Four elevator steel structure shaft columns form a square frame to form the shaft, and the 1 / 4+3 / 4 structure can extend the installation position of the ring beam.

[0014] Furthermore, the surfaces of the front wall panel and the rear wall panel are both provided with an anti-corrosion coating. The anti-corrosion layer is first sprayed on the inner and outer surfaces of the front wall panel and the rear wall panel by spraying paint or powder coating, and then installed, thereby solving the problem that it is difficult to spray anti-corrosion on the inner side of the elevator shaft column in the prior art.

[0015] Furthermore, the front wall plate and the rear wall plate are both made of steel plates.

[0016] Furthermore, the front wall panel and the rear wall panel are both integrally formed structures.

[0017] Furthermore, the front wall plate and the rear wall plate are made by cutting and bending Q235 steel plates or by roll forming using a rolling mill.

[0018] Furthermore, the two front wall side panels have the same width, and the two rear wall side panels have the same width.

[0019] Furthermore, the strip bolt hole is elliptical.

[0020] Furthermore, the bending parts of the first bending edge, the second bending edge and the third bending edge are all processed into rounded corners, so that the periphery of the elevator shaft column is rounded without edges and corners.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The utility model has a simple structure and is easy to install, which effectively improves the installation efficiency of the elevator shaft column and ensures the structural strength of the elevator shaft column, which is convenient for reducing the production cost of the column and the elevator shaft and is convenient for mass production.

[0023] 2. The utility model connects the front wall panel and the rear wall panel by staggering two strip bolt holes and rivet holes up and down, which has better strength; the front wall panel and the rear wall panel are fixed by inserting rivets in the rivet holes and adopting hydraulic riveting method, and the riveted parts extend outside the rectangular columns, so that the torsional strength and bending resistance of the overall structure are greatly enhanced.

[0024] 3. The anti-corrosion layer is first sprayed on the inside and outside of the front wall and the rear wall, and then installed by spraying paint or powder. This solves the problem that it is difficult to spray the inside of the elevator shaft column with anti-corrosion in the prior art. The elevator steel structure shaft column of the utility model is suitable for outdoor use, such as additional ladders and sightseeing ladders that need to withstand the test of rain and have high anti-corrosion requirements.
