Description

Technical Field

[0001] The present invention relates to the technical field of elevator retrofitting structures, and in particular to a modular combined elevator frame structure, an retrofitted elevator shaft and a construction method. Background Art

[0002] The houses built earlier in the city were not equipped with elevators. With the improvement of people's living standards, many people hope to add elevators outside existing buildings. At present, the installation of elevators requires a separate steel structure shaft to be designed outside the original building. The steel structure shaft usually occupies a small area and has a relatively large aspect ratio. When the elevator is installed and used, the elevator shaft will be subject to multi-directional forces such as vertical and horizontal directions. The loaded elevator shaft is designed outside the house and sometimes needs to withstand the influence of severe weather such as hurricanes. There are high requirements for the structural strength, torsion resistance, overall disturbance, and stability of the shaft. The traditional installation method of steel structure shaft is to cut the profile on site, set up the frame pipe for manual welding, the steel structure shaft beam column connection node is single, the on-site welding equipment is limited, lack of standardized processing, welding quality is difficult to control, installation accuracy is low, installation efficiency is not high, the overall frame structure is not stable, and most of the elevator's workload or vibration is borne by the steel structure shaft. In summary, existing steel structure shafts are often installed on-site by taking profiles (cutting profiles, welding profiles and other tedious installation operations), which requires a good construction site on site (in the case of a small construction area, it is very limited and cannot be constructed), and will also take up a long time on site passages. There are also major safety hazards in shaft construction. Existing steel structure shafts are easily affected by on-site construction personnel and the construction environment, and are greatly affected by human factors during the installation process. For example, there may be situations where a profile is not welded firmly or the welding is crooked. These problems will lead to low quality and low construction efficiency of the elevator shaft after construction. Summary of the invention

The frame structure layer 3 includes four cross beams 7 (such as Figure 1 As shown, preferably, the four beams 7 of the frame structure layer 3 are located in the same horizontal plane; of course, the four beams 7 of the same frame structure layer 3 may not be in the same horizontal plane, for example, the four beams 7 may have a slight height difference), and the four beams 7 are connected and fixed to the column unit 1 through the connecting member 6 (the column unit 1 of the present invention can be welded with the connecting member 6 in the factory, and the column 2 with the connected member 6 welded is as shown in FIG. Figure 2 During construction and installation, the cross beam 7 and the oblique connecting member 5 are bolted and fixed on site. The bolt holes at the connection position should be arranged as many as possible in different directions and in a symmetrical manner. A small number of bolt holes can also be asymmetrical. The connecting member 6 can be thickened according to the specific situation).

[0037] like Figure 3 As shown, the connecting member 6 is composed of a U-shaped member base 61 and an ear plate 62 folded outward at the U-shaped notch of the U-shaped member base 61. The connecting member 6 has sides 63 distributed on the left and right, and one of the sides 63 of the connecting member 6 is fixed to the side of the column unit 1 (the column 2 after the connecting member 6 is welded is as shown in FIG.

The reinforcing connectors 9 of two adjacent column units 1 are staggered in height (so that all the reinforcing connectors 9 are not on the same plane, and are staggered in height to enhance the structural strength to cope with the concentration of lateral horizontal forces). In two adjacent column units 1, the reinforcing connectors 9 of one column unit 1 are arranged at a height between the two reinforcing connectors 9 of the other column unit 1.
