[0030] Since the vertical beams and horizontal beams of the existing elevator shaft structure to be retrofitted are usually connected by welding, there are problems of insufficient connection strength and time-consuming and laborious work.

[0031] The utility model provides a retrofit elevator shaft structure 100, which strengthens the connection between the vertical beam 10 and the horizontal beam 20 through the knee brace 30, and improves the overall structural strength of the retrofit elevator shaft structure 100.

[0032] Please refer to Figures 1-3, The elevator shaft structure 100 to be installed includes vertical beams 10, horizontal beams 20 and knee braces 30. There are multiple vertical beams 10, and the multiple vertical beams 10 are arranged in parallel at intervals. The horizontal beams 20 are perpendicular to the vertical beams 10. There are multiple horizontal beams 20, and the multiple horizontal beams 20 are arranged in parallel at intervals. Both ends of each horizontal beam 20 are respectively connected to two vertical beams 10; the knee brace 30 includes a first support plate 31 and a second support plate 32. The first support plate 31 and the second support plate 32 are connected, the first support plate 31 and the second support plate 32 are perpendicularly arranged, and one of the first support plate 31 and the second support plate 32 is connected to the vertical beam 10, and the other is connected to the horizontal beam 20. In this way, the horizontal beam 20 and the vertical beam 10 form the basic framework of the elevator shaft. The first support plate 31 and the second support plate 32 of the knee brace 30 are perpendicularly arranged, so that the first support plate 31 and the second support plate 32 can respectively fit on the mutually perpendicular horizontal beam 20 and vertical beam 10, thereby supporting the horizontal beam 20 and the vertical beam 10, improving the connection strength and support strength between the two, and thus improving the overall stability of the elevator shaft structure 100 to be installed.

[0033] Preferably, knee braces 30 are provided at each connection between the vertical beams 10 and the horizontal beams 20, so as to make the connection strength between each connection point balanced and further improve the structural strength.

[0034] The connection between the first support plate 31 and the second support plate 32 is bent and forms an arc structure 33. The arc-shaped bending structure can avoid stress concentration, make the stress distribution more balanced, so that the connection between the first support plate 31 and the second support plate 32 is stronger, and avoid deformation and damage at the connection between the two.

[0035] Of course, in other embodiments, the first support plate 31 and the second support plate 32 can also be directly connected at a right angle to reduce production costs. Setting knee braces 30 at each connection between each vertical beam 10 and each horizontal beam 20 can already greatly improve the structural strength of the elevator shaft structure 100 to be installed. In order to save costs and not set the arc structure 33 here will not affect the implementation of the technical problem of this application.

[0036] Please refer to Figure 4 , In this embodiment, the first support plate 31 is connected to the horizontal beam 20, the second support plate 32 is connected to the vertical beam 10, and the first support plate 31 is of an L-shaped structure. The L-shaped structure enables the first support plate 31 to not only maintain a good fitting effect with the horizontal beam 20, but also have at least part extending towards the second support plate 32, so as to ensure the effective connection between the first support plate 31 and the second support plate 32.

[0037] It can be understood that, in another embodiment, the second support plate 32 can also be set to an L-shaped structure, that is, the second support plate 32 can extend towards the first support plate 31 while being connected to the vertical beam 10 and ensure the connection effect.

[0038] Specifically, the first support plate 31 includes a connecting section 311 and an extending section 312 that are connected to each other (in an embodiment where the second support plate 32 is L-shaped, the second support plate 32 may also include a connecting section 311 and an extending section 312 that are connected to each other). The connecting section 311 and the extending section 312 are perpendicularly arranged and form an L-shaped structure. At least one side of the connection part between the connecting section 311 and the extending section 312 is an arc surface 34. The arc surface 34 here has a similar effect to the arc structure 33 described above, which can prevent stress concentration from occurring when the connecting section 311 and the extending section 312 are stressed and twisted or bent, improve the stress sharing effect, and thus improve the overall structural strength of the knee brace 30.

[0039] In this embodiment, the direction in which the L-shaped first support plate 31 is bent is defined as the inner side, and the other direction is defined as the outer side. The inner side of the first support plate 31 has an arc surface 34, thereby preventing stress concentration on its inner side. In other embodiments, the outer side may also be provided with an arc surface 34, or both the inner side and the outer side may be provided with arc surfaces 34.

[0040] At least two connection holes 51 are formed in the first support plate 31. A connecting member 40 is inserted through each connection hole 51, and the connecting member 40 in the first support plate 31 is connected to the cross beam 20. Since the shaft structure is subjected to more lateral forces and a higher frequency of lateral forces than longitudinal forces during daily use, the number of bolt connections between the first support plate 31 and the cross beam 20 is correspondingly increased to specifically improve the support effect provided by the knee brace 30. Correspondingly, at least one connection hole 51 is formed in the second support plate 32. A connecting member 40 is inserted through each connection hole 51, and the connecting member 40 in the second support plate 32 is connected to the vertical beam 10. When the longitudinal force is not much, the number of connecting members 40 between the second support plate 32 and the vertical beam 10 is correspondingly reduced, thereby reducing the material cost and the process cost.

[0041] Specifically, the connecting member 40 is a bolt. Through the cooperation of the bolt and the nut, the disassembly and assembly are convenient and the connection strength is high. Of course, in other embodiments, structures such as screws may also be selected, and it is not limited to the cooperation structure of the nut and the bolt. Preferably, bolts with a diameter greater than 12 mm are used in this embodiment to ensure that the strength of the connecting member 40 meets the standard.

[0042] In this application, in order to improve the structural stiffness of the cross beam 20 and the vertical beam 10 itself, considering the comprehensive cost and facilitating the installation of the knee brace 30, the I-shaped beam is selected for the vertical beam 10. Specifically: each vertical beam 10 includes two first flange plates 11 and one first web plate 12. The first flange plates 11 and the first web plate 12 are perpendicular to each other, and both ends of the first web plate 12 are respectively connected to the middle parts of the two first flange plates 11 to form a vertical beam 10 with an I-shaped cross section (also known as an H-shaped), and this kind of vertical beam 10 has good torsional strength, and the space between the first flange plates 11 and the first web plate 12 can facilitate the installation of the knee brace 30.

[0043] The side of the first flange plate 11 close to the first web plate 12 is the inner side, and at least part of the cross beam 20 is connected to the inner side of the first flange plate 11. Therefore, part of the cross beam 20 is located in the area enclosed by the first flange plate 11 and the first web plate 12 (here it is not completely enclosed into an airtight area), which improves the space utilization rate and reduces the occupied space.

[0044] Please refer to Figure 5 , corresponding to the vertical beam 10, the cross beam 20 includes two second flange plates 21 and a second web plate 22. The second flange plates 21 and the second web plate 22 are perpendicular to each other, and both ends of the second web plate 22 are respectively connected to the same side ends of the two second flange plates 21 to form a cross beam 20 with a C-shaped cross section. The side of the second flange plate 21 away from the second web plate 22 is the outer side; the second web plate 22 is connected to the inner side of one of the first flange plates 11, the first support plate 31 is connected to the outer side of the second flange plate 21, and the second support plate 32 is connected to the inner side of the other first flange plate 11. In this way, the matching degree of the cross beam 20 and the vertical beam 10 is higher. The second web plate 22 of the cross beam 20 just fits on the first flange plate 11 of the vertical beam 10 to form a connection. And because the cross beam 20 and the vertical beam 10 are perpendicular, the first flange plate 11 and the second flange plate 21 are also perpendicular. At this time, the mutually perpendicular first support plate 31 and the second support plate 32 in the knee brace 30 can just be connected to the perpendicularly arranged first flange plate 11 and the second flange plate 21 to realize the reinforcement of the cross beam 20 and the vertical beam 10.

[0045] The elevator shaft structure added 100 further includes a diagonal beam 50. The diagonal beam 50 is arranged at an angle with the cross beam 20 and the vertical beam 10, and each end of the diagonal beam 50 is connected to two adjacent vertical beams 10 through at least two connecting pieces 40. The diagonal beam 50 can further improve the structural strength of the frame formed between the cross beam 20 and the vertical beam 10, transfer the stress on the adjacent vertical beams 10, and improve the overall structural strength of the elevator shaft structure added 100. At the same time, the two connecting pieces 40 further improve the connection stability between the diagonal beam 50 and the vertical beam 10 bracket, and prevent relative rotation between the diagonal beam 50 and the vertical beam 10.

[0046] In this embodiment, two connecting holes 51 are formed in the inclined beam 50, and the two connecting holes 51 are staggeredly arranged in the height direction. Each connecting hole 51 is respectively penetrated by a connecting member 40 to realize the connection with the vertical beam 10.

[0047] Preferably, the cross-section of the inclined beam 50 is L-shaped to improve the structural strength of the inclined beam 50 itself.

[0048] Compared with the prior art, the cross beam 20 and the vertical beam 10 form the basic framework of the elevator shaft. The first support plate 31 and the second support plate 32 of the knee brace 30 are vertically arranged, so that the first support plate 31 and the second support plate 32 can respectively fit on the mutually perpendicular cross beam 20 and vertical beam 10, thereby supporting the cross beam 20 and the vertical beam 10, improving the connection strength and the support strength between the two, and thus improving the overall stability of the additional elevator shaft structure 100.

[0049] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0050] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
