The main steel structure 1 includes steel columns 1.1 and multiple layers of frame beams 1.2 connected between the steel columns 1.1.

[0046] In the embodiment of the present application, three frame columns 2 are provided, which are respectively located at the four corners of the hoistway structure with the steel columns 1.1. A rectangular hoistway structure is formed between the frame columns 2 and the steel columns 1.1. As the columns of the hoistway structure, the frame columns 2 are fixedly arranged between the frame beams 1.2.

Multiple spacer beams 3 are arranged at intervals between the upper and lower adjacent frame beams 1.2.

[0048] The steel lintel 5 is arranged between the frame columns 2 on the entrance side of the hoistway structure. The steel frame door columns 4 are fixedly arranged in pairs between the steel lintel 5 and the frame beam 1.2, and an elevator door opening is formed between each pair of steel frame door columns 4.

[0049] In this application, by using the steel column 1.1 and the floor beams in the main steel structure 1 as part of the elevator hoistway structure, and cooperating with the frame column 2, the spacer beam 3, the steel frame door column 4 and the steel lintel 5 to form a prefabricated elevator hoistway for a new building. Compared with the traditional reinforced concrete shear wall structure or aerated concrete block masonry partition wall structure, the workload of the cast-in-place concrete structure is reduced, the input and use of materials such as formwork and wooden square timbers are reduced, the waste of cast-in-place concrete materials is avoided, the carbon emissions at the construction site are reduced, and the effect of green construction is achieved; compared with the prefabricated elevator hoistway, its bulk components cooperate with the structural steel column 1.1 to form an elevator hoistway, which solves the problem that the hoistway assembly hoisting cannot be realized due to the construction of the main structure roof of the new building, and this application is more conducive to ensuring the construction quality of the hoistway structure.

[0050] In this application, the frame beam 1.2, the frame column 2 and the spacer beam 3 all adopt I-shaped steel structures.

[0051] Bench-type welded embedded parts 6 are fixedly arranged on the spacer beams 3 on the left and right sides of the entrance side of the hoistway structure. The centers of the bench-type welded embedded parts 6 on each side are located on the same vertical axis, and the sides of the bench-type welded embedded parts 6 facing the inside of the hoistway structure are located in the same vertical plane. The bench-type welded embedded parts 6 are used for installing elevator guide rails.

[0052] In addition, rib plates 7 are arranged at the positions of the bench-type welded embedded parts 6 between the flange plates on the outer side of the spacer beam 3 to enhance the strength of the spacer beam 3.

[0053] Rib plates 7 are arranged between the flange plates of the frame beam 1.2 at the position of the frame column 2. The rib plates 7 and the web of the frame beam 1.2 are located on the same vertical axis. On the one hand, the rib plates 7 are used to increase the structural strength of the frame beam 1.2 and ensure the installation performance of the elevator hoistway. On the other hand, the rib plates 7 are used as positioning parts for the upper frame column 2 to avoid the problem of repeated measurement and positioning during installation.

[0054] Partition beams 3 are filled with strip partition walls 8 between each other, between partition beams 3 and frame beams 1.2, between steel frame door columns 4 and frame columns 2, and between steel lintel beams 5 and frame beams 1.2 to enclose the elevator hoistway. Angle steels 9 are fixed on partition beams 3, frame beams 1.2, steel frame door columns 4, frame columns 2 and steel lintel beams 5. The strip partition wall 8 is attached to the angle steel 9 and fixed to the angle steel 9 through hook bolts 10. The hook of the hook bolt 10 hooks on the angle steel 9, and the other end passes through the strip partition wall 8 and is locked by a nut.

The positioning component 11 includes a pair of upper clamping plates 11.1 for clamping on both sides of the flange plate of the frame column 2. On the same side of the upper clamping plate 11.1, two vertical plates 11.2 for attaching to the outer side of the flange plate of the frame column 2 are fixed. At the butt joint of the two vertical plates 11.2, there is a fixing plate 11.3.

Then install the frame column 2 to be installed between the upper and lower frame beams 1.2, and make the upper clamping plate 11.1 clamp on both sides of the flange plate of the frame column 2. The vertical plate 11.2 fits against the outside of the flange plate of the frame column 2 to position the frame column 2 to be installed, and then carry out the welding construction of the frame column 2. Then install the upper spacer beam 3. Repeat Step 4 and Step 5 to successively install the rib plates 7, frame columns 2, and spacer beams 3;

[0062] Step 6: Locate the position of the bench - type welded embedment 6 on the spacer beam 3, install the bench - type welded embedment 6, and then install the steel lintel 5 and steel frame door columns 4 for each floor;

[0063] Step 7: Angle steels 9 are fixed on the spacer beam 3, frame beam 1.2, steel frame door column 4, frame column 2, and steel lintel 5. Strip partition walls 8 are filled between the spacer beam 3 and the spacer beam 3, between the spacer beam 3 and the frame beam 1.2, between the steel frame door column 4 and the frame column 2, and between the steel lintel 5 and the frame beam 1.2.
