Detailed Description of the Preferred Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-4As shown in the figure, this elevator hoistway for building construction includes a machine room floor 11 and an auxiliary floor 10. The machine room floor 11 and the auxiliary floor 10 are located at the top floor of the building elevator. The machine room floor 11 and the auxiliary floor 10 are constructed by columns 1 and crossbeams. The columns 1 and the crossbeams are fixed by connecting bolts 13. The machine room floor 11 is located above the auxiliary floor 10, and there is a checkered steel plate 6 separating the machine room floor 11 and the auxiliary floor 10. There are guardrails around the lower parts of the machine room floor 11 and the auxiliary floor 10. The guardrails are composed of several guardrail square tubes 9, and the size of the guardrail square tubes is 30*30*3. This is to prevent animals or children from drilling into the elevator hoistway. There is a ladder 8 and a drum rack 7 in the auxiliary floor 10. Several drums 12 are connected to the drum rack 7. The drums are used to install wire ropes, traction ropes, etc. There is a load-bearing beam 4 at the top of the auxiliary floor 10, and the upper end of the load-bearing beam 4 is a checkered steel plate 6. There is a load-bearing beam elevation beam 5 at the bottom of the machine room floor 11, on which machine room components such as the main engine, speed limiter, and control cabinet can be installed.

[0020] As Figure 1 , Figure 2 shown in the figure, the crossbeams include crossbeam Ⅰ2 and crossbeam Ⅱ3. The crossbeam Ⅰ2 and the crossbeam Ⅱ3 are H-shaped steels. The size of the crossbeam Ⅰ2 is 150*100, and the size of the crossbeam Ⅱ3 is 150*150. The crossbeam Ⅰ2 is installed between the side columns 1, and the crossbeam Ⅱ3 is installed between the front and back columns 1. The two ends of the crossbeams are connected and fixed to the columns 1 by connecting bolts 13, forming an upright elevator hoistway as a whole. The elevator hoistway is divided into several layers by the checkered steel plate 6.

[0021] The drum rack 7 is a channel steel with grooves inside. There are several equally spaced round holes in the grooves. The middle shaft of the drum 12 has a through hole, which matches the round holes on the drum rack 7. After aligning the middle shaft of the drum 12 with the drum rack 7, a fixing pin is inserted to connect and fix the drum 12. The number of drums 12 is set according to the number of wire ropes and traction ropes. Each drum 12 collects 1 wire rope or traction rope in sequence according to the wire rope or traction rope, ensuring that the wire rope or traction rope will not be damaged.

[0022] As Figure 3 , Figure 4 shown in the figure, the checkered steel plate 6 is located at the bottom of the machine room floor 11. The thickness of the checkered steel plate 6 is 5 mm. There are two cable grooves 6-2 in the middle of the checkered steel plate 6. The four sides of the checkered steel plate 6 are connected and fixed to the crossbeams by screws, which are detachable. This is convenient for raising the elevator floor during building construction. There are two reinforcing ribs 6-1 on the checkered steel plate 6 to enhance its own strength and load-bearing capacity.

[0023] The load-bearing beam 4 and the crossbeam are connected by mortise and tenon joints. The top of the drum rack 7 passes through the cable groove 6-2 in the middle of the checkered steel plate 6. The cables extend downward from both ends of the drum rack 7 and are connected to the drums 12 to release stress.

[0024] The structure of the utility model is simple and the framework is firm. Since it is an H-shaped steel frame column type elevator shaft, the elevator shaft can be installed in advance before the construction of the building is completed. When the building construction reaches the fifth floor, the elevator can be installed on site. The diamond plate on the top floor is detachable and can be further installed upward along with the progress of the building height. The roller frame connecting the steel wire rope and the traction rope can avoid the problem of releasing its tension during installation, meet the needs of construction personnel to go up and down, and improve the safety of personnel use.

[0025] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
