An installation method for an elevator framework of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.
As shown in Fig. 1 to Fig. 8, an installation method for an elevator framework of the present disclosure is illustrated. The elevator framework includes a plurality of upper and lower pillars 1 connected in sequence and arranged at four corners, and cross beams perpendicularly connected to two adjacent pillars 1 at joints of the upper and lower pillars 1. The installation method includes the following steps that:

S1: the cross beams 2 are connected with the pillars 1: Four connection sheets 23, two cross beams 2 and two pillars 1 are used; two ends of the cross beams are provided with cavities 22 to make the two pillars 1 parallel with each other; the four connection sheets 23 are inserted into the four cavities 22 of the two cross beams 2 and are fixed through bolts; the end portions of the connection sheets respectively press against the upper and lower ends of the pillars 1 and are fixed through bolts, so as to form a "square"-shaped structure;
S2: the upper and lower pillars 1 are located: The pillar 1 is a vertical corner profile; the vertical corner profile includes two vertical sections 10 that are perpendicular to each other and a bent section 11 that connects the two vertical sections 10; a connection slot 12 is formed inside the bent section 11; the inner side of the bent section 11 of the vertical corner profile is provided with a fixed bed 14; two locating columns 13, two locking columns and two "square"-shaped structures in the step S1 are used; one end of each of the two locating columns 13 is inserted into the connection slots 12 of the two pillars 1 of any one of the "square"-shaped structures; the two locking columns pass through the fixed beds 14, are inserted into the connection slots 12 and resist against the locating columns 13; the connection slots 12 of the two pillars 1 of the other "square"-shaped structure are sheathed at the other ends of the locating columns 13 to locate the upper and lower pillars 1 of the "square"-shaped structure, so as to form a "
"-shaped structure;

The fixed beds 14 are flat and straight, and have included angles of 45 degrees to the vertical sections 10; the included angles between the fixed beds 14 and the vertical sections 10 may also be other angles, as long as notches of the connection slots 12 are opposite to the fixed beds 14. However, in consideration of the convenience of installation, a 45-degree angle should be selected, and only vertical perforation needs to be performed on the middle portions of the fixed beds 14 to cause the locking columns to be successfully threaded into the connection slots 12. In consideration of the convenience of perforation, the fixed bed 14 should be flat and straight. If it has a curved surface or a slope, a perforation position is hard to locate, and inclined holes are easy to generate in the perforation process, so that it is hard to ensure that the locking columns are successfully inserted into the connection slots 12 of the pillars. The locking column may be a screw, a stud and a shaft pin. In consideration of the cost and the convenience of use, the screw should be selected. If the stud is used, the relatively large end portion of the stud would occupy the limited volume of the fixed bed 14. If the shaft pin is used, the pin shaft is easily inserted into the connection slot 12 too much to cause the end portion of the shaft pin to be remained in the fixed bed 14 too little, and this cannot fix the shaft pin well.
