Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1 to 3, the present invention discloses a steel structure elevator shaft structure, which is characterized in that the structure comprises at least one shaft 100, a plurality of anti-buckling supporting beams 200 and supporting vertical beams 300 arranged at two sides of the shaft 100; specifically speaking, compare with traditional steel construction well 100, add two support upright beams 300 in the well structure in this application, two support upright beams 300 establish respectively and be in well 100 both sides. Compared with the conventional hoistway 100, in the present application, two supporting vertical beams 300 are respectively added to both sides of the hoistway 100 to improve the stability of the whole hoistway structure.

Specifically, the hoistway structure may be only one hoistway 100, or a plurality of hoistways 100 may be connected together, when two hoistways 100 are connected together, the two hoistways 100 are connected by the buckling-restrained brace beam 200, the two support vertical beams 300 are respectively located at two sides of the two hoistways 100, and the support vertical beams 300 and the hoistways 100 are connected by the buckling-restrained brace beam 200; by analogy, when there are more than two hoistways 100, multiple hoistways 100 and two support uprights 300 are connected together in this manner.

At least one hoistway 100; the hoistway 100 includes four column assemblies 110 and a plurality of cross beams 130 connecting the four column assemblies 110 together; in this embodiment, the four column assemblies 110 are connected to the cross member 130 to form a steel structure having a substantially rectangular parallelepiped shape, and the hoistway 100 mainly functions to support an elevator, which can ascend and descend in the hoistway 100.

In this embodiment, a hoistway structure is provided with a plurality of buckling restrained braced beams 200 and supporting uprights 300 disposed at both sides of a hoistway 100, and the supporting uprights 300 are connected to a mast assembly 110 in the hoistway 100 through the buckling restrained braced beams 200.

By connecting the hoistway 100 and the support uprights 300 by the buckling restrained brace beam 200, the overall aspect ratio of the hoistway structure is reduced, the overall stability of the hoistway structure is improved, and thus, the dimensional specifications of the column assembly 110 and the cross member 130 can be appropriately reduced.

The hoistway 100 further includes a plurality of connectors 120 including a connecting plate 121 and a plurality of bolts 122; in the structure in which the cross beam 130 is connected to the column assembly 110, one end of the connecting plate 121 is fixed to the column assembly 110 by the bolt 122, and the other end is fixed to the cross beam 130 by the bolt 122.

Specifically, in the hoistway structure of the present application, the column assembly 110 is connected to the column assembly 110 through the cross beam 130, and the column assembly 110 is connected to the cross beam 130 through the connecting member 120, specifically, the column assembly 110 is fixedly connected to the cross beam 130 through the bolt 122. The cross beam 130 and the column assembly 110 are semi-rigidly connected by the bolts 122, and compared with the welded rigid connection, the semi-rigid connection has better ductility, and if the hoistway structure is bent, the hoistway structure can still achieve secondary stability. In addition, bolted 122 connections are more material efficient than welding (welding can waste a significant amount of material).

The column assembly 110 includes an upper column 111 and a lower column 112, and the upper column 111 and the lower column 112 are connected by a connecting member 120.

The hoistway 100 is rectangular, and includes a first column assembly 100a, a second column assembly 100b, a third column assembly 100c, and a fourth column assembly 100d, wherein the first column assembly 100a is connected to the second column assembly 100b through a connecting member 120, the second column assembly 100b is connected to the third column assembly 100c through the connecting member 120, and the third column assembly 100c is connected to the fourth column assembly 100d through the connecting member 120.

Specifically, the components in the hoistway structure are connected together through bolts 122, so that the hoistway structure can be conveniently installed on site, bolt 122 holes on the column assemblies 110 and the cross beams 130 are prefabricated, if the construction space on site is enough, a part of the hoistway structure can be installed firstly, and the rest parts are installed on site, so that the overall installation time can be reduced, and if the construction space on site is small, each single component (such as a single cross beam 130, a single supporting upright beam 300, a single upper column 111 and a single lower column 112) in the steel structure can be transported to the site and then installed one by one; the bolted 122 connection may facilitate removal of the hoistway structure.

The two ends of the anti-buckling supporting beam 200 are respectively provided with a connecting lug seat 210, and the two connecting lug seats 210 in the anti-buckling supporting beam 200 are respectively connected with the upright post assembly 110 and the supporting upright beam 300 through the connecting piece 120.

In this embodiment, the hoistway 100 and the hoistway 100 are connected by the buckling restrained brace beams 200, the hoistway 100 and the support vertical beams 300 are connected by the buckling restrained brace beams 200, and the support vertical beams 300 assist the steel structure support, thereby improving the overall stability of the hoistway structure.
