[0002] As people's quality of life improves, they have higher requirements for the comfort and convenience of their living environment. More and more villas are equipped with home elevators. Figure 1 to Figure 2 As shown, the elevator rail frame 100 of the existing home elevator includes four columns 1 arranged in the vertical direction, and a rear beam 2 and a front beam 3 welded to the front and rear sides of the columns 1. A side plate 4 is provided between the two columns 1 on the left side and between the two columns 1 on the right side to connect the two columns 1 on the same side. The side plate 4 is fixedly connected to the wall of the elevator shaft to fix the entire elevator rail frame 100 in the elevator shaft.
[0003] The problem with the existing elevator track frame 100 is that the column 1 is connected to the crossbeam and the side plate 4 by welding, which not only causes stress concentration and premature oxidation and fracture at the welding point, but also causes great difficulties in transportation and installation operations due to the overall length of the column.

[0038] like Figures 3 to 9 An assembled elevator track frame is shown, wherein the elevator track frame 200 includes a plurality of pairs of U-shaped steel beams 10 , a plurality of cross beams 20 , and a plurality of pairs of connecting bolt groups 30 .
[0039] Embodiment 1
[0040] like Figure 3 , Figure 4 As shown, the steel beam 10 includes a side plate 11, a pair of end arms 12 formed at the front and rear ends of the side plate 11, and two edge plates 13 respectively formed at the free ends of the two end arms 12 and extending toward each other beyond the inner side.
[0041] The two pairs of steel beams 10 are arranged opposite to each other, and multiple pairs of steel beams 10 are stacked in the vertical direction to form two opposite steel beam bodies. The opening sides of the paired steel beams 10 are opposite to each other.
[0042] Part of the cross beams 20 are fixedly installed on the rear side of the steel beam 10, and part of the cross beams 20 are fixedly installed on the front side of the steel beam 10, and the number of the cross beams 20 fixed on the rear side of the steel beam 10 (or the steel beam body) is far greater than the number of the cross beams 20 fixed on the front side of the steel beam 10 (or the steel beam body).
[0043] The two ends of the cross beam 20 fixed to the rear side of the steel beam 10 are respectively fixedly connected to the overlapping ends of two upper and lower opposite steel beams 10, so as to connect the butt ends of the upper and lower opposite steel beams 10 into a whole.
[0044] The cross beam 20 includes an I-shaped connecting rod 21 and end plates 22 formed at the left and right ends of the I-shaped connecting rod 21. The upper and lower parts of the end plates 22 are connected to two adjacent edge plates 13 on the opposite steel beam 10 through at least one pair of connecting bolt groups 30, so that the butt ends of the two opposite steel beams 10 are connected as a whole.
[0045] The widths of the upper and lower wing plates of the I-shaped connecting rod 21 (dimensions in the front-rear direction, the same below) and the width of the end plate 22 are consistent with the width of the edge plate 13 , and at least cannot be greater than the width of the edge plate 13 .
[0046] The two ends of the cross beam 20 fixed on the front side of the steel beam 10 are either fixedly connected between two adjacent edge plates 13 at the butt ends of two upper and lower steel beams 10, or connected to the middle of the edge plate 13. Generally, only two or three cross beams 20 are arranged on the front side (of the steel beam body), and the cross beam 20 is connected to the upper and lower positions of the steel body formed by stacking a plurality of steel beams 10.
[0047] During installation, the side plate 11 of the steel beam 10 is fixedly connected to the shaft wall of the elevator shaft. The elevator rail is fixedly installed on the inner wall of the side plate 11 and is located in the front and rear center position.
[0048] Embodiment 2
[0049] like Figures 5 to 7 As shown, the main difference between this embodiment and the above embodiment is that a plug-in arm 14 is provided. Other structural features can refer to the above embodiment and can be flexibly adjusted and selected, so they will not be described in detail.
[0050] In this embodiment, except for the pair of steel beams 10 at the bottom, the lower ends of the other steel beams 10 are matched with plug-in arms 14. The plug-in arms 14 include a wall plate 14a and a wall plate 2 14b, and the cross section of the plug-in arms 14 is L-shaped (see FIG. Figure 5 ).
[0051] The upper part of the wall plate 14a of the plug arm 14 is attached to the inner wall of the edge plate 13 (i.e., the inner wall surface b) of the steel beam 10, and the upper part of the wall plate 14b of the plug arm 14 is fixed to the inner wall of the end arm 12 (i.e., the inner wall surface a) of the steel beam 10 through a bolt group 142. The lower part of the plug arm 14 extends downwardly to a certain length relative to the lower end surface of the steel beam 10.
[0052] The lower portion of the plug-in arm 14 can be inserted into the inner side of the angle formed at the junction of the end arm 12 and the edge plate 13 of the adjacent lower section steel beam 10 .
[0053] The two paired connecting bolt groups 30 can respectively connect the upper and lower parts of the wall plate 14a of the plug-in arm 14 to the edge plate 13 (at the same height) and the end plate 22 of the crossbeam 20 to form a whole.
[0054] A plurality of reinforcing ribs 141 are arranged alternately up and down on the inner side of the corner of the plug arm 14 .
[0055] After the insertion arm 14 is provided, the wall surface of the upper and lower butted steel beams 10 can form a better verticality, which helps to reduce the difficulty of assembly and can improve the overall strength and rigidity of the assembled steel beam body.
[0056] like Figure 7 , Figure 8 As shown, the lower end of the outer side surface of the wall plate 14a and the lower end of the outer side surface of the wall plate 2 14b are both formed with an inclined surface 143. The inclined surface 143 is inclined inwardly relative to the outer side surface of the wall plate 14a or the outer side surface of the wall plate 2 14b from top to bottom, so as to facilitate the insertion of the plug arm 14 into the inner side of the lower steel beam 10.
[0057] like Fig. 9 As shown, the plug arm 14 further includes a wall panel three, and the wall panel one 14a and the wall panel three are arranged at the (left and right) ends of the wall panel two 14b, so that the cross section of the plug arm 14 is U-shaped.
[0058] On the outer side of the wall panel 14a and the outer side of the wall panel 3, a plurality of semi-cylinders 144 are arranged alternately in front and back. The wall surface of the semi-cylinder 144 facing the inner wall of the side panel 11 and the wall surface facing the inner wall of the edge panel 13 are both curved walls 145. The outer diameter of the semi-cylinder 144 gradually increases from bottom to top, so that when the plug-in arm 14 is inserted into the inner side of the adjacent steel beam 10 at the lower part, the semi-cylinder 144 will be pressed by the inner wall of the side panel 11 or the inner wall of the edge panel 13 and be flattened.
[0059] By improving the structure of the splice arm 14, the verticality and stability of the stacked steel beams 10 can be improved, which not only facilitates assembly but also improves the integrity of the assembled steel beam body.
[0060] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. The present invention can be improved in many aspects without violating the overall concept, and those familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical concept disclosed by the present invention should still be covered by the claims of the present invention.
