In the preferred embodiment of the present invention, the framework 1 has a rectangular cross-sectional profile and includes four main posts 11 and four wall units 13.
The main posts 11 of the framework 1 are disposed at four corners of the framework 1. Each of the main posts 11 of the framework 1 is a steel bar that is made by casting or rolling. Each of the main posts 11 of the framework 1 has a rectangular cross-sectional profile and has a length of about twelve to thirteen meters (12-13 m).
Each of the main posts 11 of the framework 1 has a bottom combined with a fixing seat 111 by soldering. The fixing seat 111 of each of the main posts 11 has a surface formed with a plurality of fixing holes 112, and the elevator further comprises a plurality of fastening bolts 521 mounted on the foundation 52 and extended through the fixing holes 112 of the fixing seat 111 of each of the main posts 11, and a plurality of fastening nuts 522 screwed onto the fastening bolts 521 and pressing the fixing seat 111 of each of the main posts 11 to lock the fixing seat 111 of each of the main posts 11 onto the foundation 52.
Each of the wall units 13 of the framework 1 has a length smaller than that of each of the main posts 11. Each of the wall units 13 of the framework 1 is located between and abuts any two adjacent main posts 11 by soldering, and any two adjacent wall units 13 of the framework 1 abut each other. Each of the wall units 13 of the framework 1 is combined with a plurality of transverse bars 12. At least one of the wall units 13 of the framework 1 has a surface formed with a plurality of openings 133 each corresponding to one of a plurality of floors of the building 5. Each of the wall units 13 of the framework 1 consists a plurality of hollow steel bars 131 which are juxtaposed to each other and are combined by soldering. Each of the steel bars 131 of each of the wall units 13 has a substantially C-shaped profile and has a side formed with an elongate slot 132 facing outward.
Each of the transverse bars 12 of the framework 1 is located between any two adjacent main posts 11. The transverse bars 12 of the framework 1 are parallel with each other and are extended through each of the wall units 13 to reinforce the strength of each of the wall units 13. Each of the transverse bars 12 of the framework 1 is perpendicular to each of the wall units 13 and is extended through each of the steel bars 131 of each of the wall units 13.
The foundation 52 is located at a bottom of the passage 51 of the building 5 and has an inner portion formed with a mounting recess 520 to partially receive the framework 1. The mounting recess 520 of the foundation 52 is located at the ground 501 of the first floor 50 of the building 5 and has a depth of about one to one point five thirteen meters (1-1.5 m). The fastening bolts 521 are mounted on a bottom face of the mounting recess 520 of the foundation 52.
In assembly, the framework 1 is assembled previously in the factory. At this time, the cab 2, the drive motor 3, the counterweights 4, the cables, the electricity control box and other appliances and parts are received in the receiving space 10 of the framework 1. Then, the framework 1 is transported to the building 5. Then, the hanging ear 113 of the framework 1 is hung by a truck crane so that the framework 1 is inserted into the passage 51 of the building 5. When the framework 1 is inserted into the mounting recess 520 of the foundation 52, the fixing holes 112 of the fixing seat 111 of each of the main posts 11 are aligned with and mounted on the fastening bolts 521. Then, the framework 1 is plumbed to calibrate the verticality of the framework 1. Then, the fastening nuts 522 are screwed onto the fastening bolts 521 and press the fixing seat 111 of each of the main posts 11 to lock the fixing seat 111 of each of the main posts 11 onto the foundation 52 so as to lock the framework 1 onto the foundation 52. Then, concrete 6 is grouted into the passage 51 of the building 5 to surround the framework 1 so as to fix the framework 1 in the passage 51 of the building 5. At this time, the wall units 13 of the framework 1 stop the concrete 6 to prevent the concrete 6 from entering the receiving space 10 of the framework 1. In such a manner, the concrete 6 is inserted into the elongate slot 132 of each of the steel bars 131 so that each of the wall units 13 of the framework 1 is combined with the concrete 6 solidly and stably to enhance the structural stability of the framework 1. In addition, the electric appliances in the framework 1 has to be waterproofed so as to prevent the electric appliances from being wetted. In addition, a pump is placed in the foundation 52 to pump and carry away the water in the foundation 52.
Accordingly, the elevator has a modularized framework 1 which is assembled previously in the factory so that the workers can directly insert the framework 1 into the passage 51 of the building 5 without having to assemble the framework 1 at the site of the building 5, thereby enhancing the working efficiency, and thereby decreasing the cost of construction. In addition, the concrete 6 is inserted into the elongate slot 132 of each of the steel bars 131 so that each of the wall units 13 of the framework 1 is combined with the concrete 6 solidly and stably to enhance the structural stability of the framework 1.
