Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating an elevator installation structure according to an embodiment of the present disclosure, which includes a support frame 100, a connecting member 200, and a reinforcing member 300. The support frame 100 includes a first support beam 110 and a second support beam 120, and the first support beam 110 and the second support beam 120 are fixedly connected to each other to form the support frame 100 for providing a mounting base for the elevator guide rail 400. The connecting member 200 connects the elevator guide rail 400 and the first support beam 110, and serves to stably connect the elevator guide rail 400 and the support frame 100, so that the support frame 100 bears a force for fixing the elevator guide rail 400. The reinforcing assembly 300 is fixedly connected to the connecting member 200 and the second support beam 120, so that the elevator guide rail 400 is not only connected to the first support beam 110, but also connected to the second support beam 120 through the reinforcing assembly 300, and the first support beam 110 and the second support beam 120 share the acting force for fixing the elevator guide rail 400, thereby greatly improving the connection strength between the support frame 100 and the elevator guide rail 400.
Specifically, the first support beam 110 and the second support beam 120 are steel beams at a floor construction site to form a steel structure foundation of the steel structure building. Before the floor bearing plate is poured, only the first supporting beam 110 connected with the connecting piece 200 cannot bear the acting force of the fixed elevator guide rail 400 alone, and after the floor bearing plate is poured, the first supporting beam 110, the second supporting beam 120 and the floor bearing plate form a whole body to bear the acting force of the fixed elevator guide rail 400 together, so that a stable elevator guide rail 400 installation foundation can be provided. Specifically, in the present embodiment, the first supporting beam 110 and the second supporting beam 120 are cylindrical steel beams, the first supporting beam 110 and the second supporting beam 120 are perpendicular to each other to form a rectangular structure, a steel column in the plumb direction is disposed at the joint of the first supporting beam 110 and the second supporting beam 120, and the horizontal section of the steel column is rectangular for supporting the floor in the plumb direction.
The support frame 100 further includes a third support beam 130 and a fourth support beam 140, and the third support beam 130 and the fourth support beam 140 are disposed inside the support frame. Specifically, the third support beams 130 are respectively connected with the first support beams 110 oppositely arranged and the second support beams 120 oppositely arranged, the fourth support beams 140 are connected with the third support beams 130 and the support frame, the connection stability between the first support beams 110 and the second support beams 120 is improved from the inside of the support frame through the arrangement of the third support beams 130 and the fourth support beams 140, and meanwhile, the third support beams 130 and the fourth support beams 140 are also part of the support frame 100, and the structural stability of the support frame 100 can be improved as well. Specifically, in the present embodiment, the third support beam 130 is a main beam of a floor steel structure, and the fourth support beam 140 is a secondary beam of the floor steel structure. The two third supporting beams 130 are disposed perpendicular to each other, and the fourth supporting beams 140 are symmetrically disposed between the third supporting beams 130 and the first supporting beams 110, so as to improve the connection stability between the third supporting beams 130 and the second supporting beams 120, and assist the third supporting beams 130 to improve the structural stability of the supporting frame 100 from the inside.
The connector 200 is used to connect the elevator guide rail 400 and the support frame 100. Specifically, the connector 200 is a wall-attached support for providing an installation base of the elevator guide rail 400, and the connector 200 connects the elevator guide rail of the elevator guide rail 400 with the first support beam 110 so that the force of the elevator guide rail can be transmitted to the first support beam 110 through the connector 200. Specifically, in the present embodiment, the connecting end of the wall-attached support is connected to the elevator guide of the elevator guide 400, and the supporting end of the wall-attached support is connected to the midpoint of the first support beam 110, so that the left and right ends of the first support beam 110 equally bear the force for fixing the elevator guide 400.
The reinforcement assembly 300 is fixedly connected to the second support beam 120 and the connecting member 200, so that the second support beam 120 jointly bears the force of fixing the elevator guide rail 400 through the connecting member 200 and the reinforcement assembly 300. The reinforcing assembly 300 includes a reinforcing pipe 310, and one end of the reinforcing pipe 310 is connected to the supporting end of the connecting member 200 and the other end is connected to the second supporting beam 120.
Specifically, the number of the reinforcing pipes 310 is at least two, the two reinforcing pipes 310 are respectively connected to different second supporting beams 120, and the two second supporting beams 120 arranged in parallel are connected to the supporting end of the connecting member 200, so that the acting force for fixing the elevator guide rail 400 can be distributed to the two second supporting beams 120, and the structural strength requirement for a single second supporting beam 120 is reduced. Specifically, in the present embodiment, the number of the reinforcing pipes 310 is two, and the two reinforcing pipes 310 are symmetrically disposed between the second supporting beams 120 and the connecting member 200, so that the two second supporting beams 120 receive the same acting force, and the structural stability of the whole supporting frame 100 is improved. Specifically, in the present embodiment, the reinforced pipe 310 is a steel pipe, and the specification of the steel pipe is preferably 168mmx10 mm.
The shape, size, and material of the reinforced pipe 310 are not limited to those described in the present embodiment, and those skilled in the art can adjust the shape, size, and material of the reinforced pipe 310 according to the specific circumstances.
In some other embodiments, the number of the reinforcing pipes 310 is an even number, and a plurality of the reinforcing pipes 310 are disposed at a distance from each other on the second support beam 120 and are commonly connected to the support end of the connecting member 200 to commonly bear a force of fixing the elevator guide rail 400 by the plurality of the reinforcing pipes 310. Meanwhile, the plurality of reinforcing tubes 310 are symmetrically disposed, which can provide structural stability of the support frame 100 itself. It will be appreciated that the greater the number of reinforcement tubes 310, the greater the stability of the connection it provides, and the greater its cost. When the number of the reinforced pipes 310 exceeds a certain range, the increase in the connection stability provided by increasing the number of the reinforced pipes 310 is not significant, but the cost is significantly increased. Therefore, in the present embodiment, the number of the reinforcing tubes 310 is preferably four.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an elevator installation structure according to another embodiment of the present application. In some other embodiments, the reinforced pipe 310 is a single piece, a plurality of fourth supporting beams 140 are arranged on the side opposite to the reinforced pipe 310, and a part of the reinforced pipe 310 is replaced by the arrangement of the fourth supporting beams 140, so that the effects of saving engineering materials and reducing cost are achieved.
The angle between the reinforcing tube 310 and the first support beam 110 is greater than 30 degrees. By controlling the connection position of the reinforcing pipe 310 on the second support beam 120, the angle between the reinforcing pipe 310 and the first support member can be adjusted. The smaller the angle between the reinforcing tube 310 and the first support beam 110, the smaller the force carried by the reinforcing tube 310 can be used to fix the elevator guide rail 400 after being resolved, i.e., the lower the connection strength of the connecting member 200 connecting the elevator guide rail 400 and the support frame 100. The larger the angle between the reinforcing pipe 310 and the first support beam 110 is, the more installation space occupied by the reinforcing pipe 310 is, which affects the installation of the third support beam 130 and the fourth support beam 140 in the support frame. Therefore, in the present embodiment, the angle between the reinforcing pipe 310 and the first support beam 110 is preferably 45 degrees.
Referring to fig. 3, fig. 3 is an enlarged view of a structure in fig. 1. In some embodiments, the reinforcing assembly 300 further includes a mounting member 320, the mounting member 320 being disposed on the second support beam 120 for connecting the second support beam 120 and the reinforcing pipe 310. In the embodiment, the mounting member 320 is a web rib, and the web rib is preferably made of Q235B steel with a thickness of 10mm, and the web rib is fixedly arranged on the steel beam by welding, so as to provide a mounting base for the reinforced pipe 310 and prevent the reinforced pipe 310 from sliding on the second support beam 120 when being stressed.
In some embodiments, the reinforcing assembly 300 further includes fixing members 330, the fixing members 330 are disposed at both ends of the reinforcing pipe 310, and the fixing members 330 are used for improving the connection strength between the ends of the reinforcing pipe 310 and the supporting ends of the second supporting beam 120 and the connecting member 200. Specifically, in the present embodiment, the fixing member 330 is a fixing plate, and the fixing plate is preferably made of Q235B steel material with a specification of 400 × 250 × 12 mm. One end of the retaining plate is welded to the web ribbing and the opposite end of the retaining plate is welded into the reinforcing tube 310.

The reinforcement assembly 300 further includes a connecting rod 340, the connecting rod 340 being disposed between the two reinforcement tubes 310. Specifically, the two ends of the connecting rod 340 are symmetrically disposed between the two reinforcing tubes 310, so that the two reinforcing tubes 310 bear the same acting force, and the overall structural stability of the support frame 100 is prevented from being affected by the single reinforcing tube 310 due to the excessive load.
In some embodiments, a plurality of tie rods 340 are disposed parallel to each other between the two reinforced tubes 310 to further provide the strength of the connection between the two reinforced tubes 310.
It should be noted that the number and arrangement of the connecting rods 340 are not limited to those of the present embodiment, and for example, a plurality of embodiments may be arranged between the reinforcing tubes 310 in a crossing manner.
An embodiment of the present application further provides a lifting system, including the above-described elevator installation structure, elevator guide rail, and elevator.
