Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a staircase structure which can prevent a frame column in a staircase from forming a short column. Background Art

[0002] Stairs are vertical transportation facilities used to connect different floors in buildings. They are not only an important part of people's daily lives, but also an important element in architectural design. The design of stairs involves many aspects, including the type, structure, material, safety, and aesthetics of the stairs. Stairs are usually composed of steps, platforms, railings, and handrails. Their design needs to meet ergonomic requirements to ensure that users can go up and down the stairs comfortably and safely.

[0003] In the structural design of stairs, short columns are an issue that requires special attention. Short columns refer to columns in the frame structure whose net height to section height ratio is no more than 4. Since short columns have high stiffness and poor ductility, they are prone to brittle shear failure when subjected to horizontal loads, especially earthquakes. The existence of short columns will reduce the seismic performance of the entire structure and increase the danger of the building in an earthquake. The short columns on the platform inside the stairwell have a great impact on the escape route after earthquake damage. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a staircase structure which avoids the formation of short columns in the staircase frame columns, and has the advantages of simple structure and good seismic performance.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A staircase structure for preventing staircase frame columns from forming short columns, comprising:

[0007] Supporting corbels, which are arranged on frame columns to prevent the frame columns from forming short columns;

[0008] An interlayer slab, the interlayer slab is arranged on the supporting corbel, and the interlayer slab is connected to at least one stair inclined slab;

[0009] A sliding support assembly is arranged between the interlayer plate and the supporting corbel, and is respectively connected to the supporting corbel and the interlayer plate.

[0010] Compared with the prior art, the present application eliminates the need for a ladder column structure by setting the interlayer slab on the supporting corbels on the frame columns, thereby effectively avoiding the formation of short columns by the frame columns, helping to reduce the impact of the staircase components on the overall structural stiffness and improving the seismic performance of the overall structure.

[0011] As a preferred solution of the utility model, the interlayer plate includes a plate body and a ladder beam, and the ladder beam is arranged on the bottom wall of the plate body and connected to the sliding support assembly.

[0012] By adopting the above solution, the ladder beam can transfer the load of the stair inclined plate and the plate body to the supporting corbel, which further simplifies the structure and improves the stability of the structure.

[0013] As a preferred solution of the utility model, the sliding support assembly includes:

[0014] A first support member, wherein the first support member is arranged on the bottom wall of the interlayer plate;

[0015] a second support member, the second support member being arranged on the top wall of the supporting corbel;

[0016] A lubricating layer is disposed between the first supporting member and the second supporting member, and is used to reduce friction between the first supporting member and the second supporting member.

[0017] By adopting the above-mentioned scheme, a lubricating layer is arranged between the first supporting member on the interlayer plate and the second supporting member arranged on the supporting corbel. When an earthquake occurs, the first supporting member and the second supporting member can achieve relative sliding under the action of the lubricating layer, so as to reduce the influence of the stair components on the overall structural stiffness and improve the seismic performance.

[0018] As a preferred solution of the utility model, the first supporting member includes a first fixing member and a first force-bearing plate, the first fixing member is arranged on the interlayer flat plate, and the first force-bearing plate is respectively connected to the first fixing member and the lubricating layer.

[0019] By adopting the above solution, the bearing capacity and stability of the staircase structure are improved through the provision of the first fixing member and the first load-bearing plate.

[0020] As a preferred solution of the present utility model, the second support member includes a second fixing member and a second force-bearing plate, the second fixing member is arranged on the supporting corbel, and the second force-bearing plate is respectively connected to the second fixing member and the lubricating layer.

[0021] By adopting the above solution, the bearing capacity and stability of the staircase structure are improved through the provision of the second fixing member and the second load-bearing plate.

[0022] As a preferred solution of the present invention, the lubricating layer is a graphite layer.

[0023] By adopting the above-mentioned scheme, when a graphite layer is used as a lubricating layer, the friction between the first support member and the second support member can be reduced, and the sliding performance between the first support member and the second support member can be improved, so that during an earthquake, the influence of the stair components on the overall structural stiffness can be more effectively reduced, thereby improving the seismic resistance.

[0024] The above-mentioned staircase structure that avoids the formation of short columns in the staircase frame columns has the following beneficial effects: by setting the interlayer slab on the supporting corbels on the frame columns, there is no need to set up a stair column structure, thereby effectively avoiding the formation of short columns in the frame columns. At the same time, through the setting of the first support member, the second support member and the lubricating layer, the interlayer slab and the supporting corbels can slide against each other. When an earthquake occurs, the influence of the staircase components on the overall structural stiffness can be effectively reduced, thereby improving the seismic performance of the overall structure. At the same time, the structure is relatively simple and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

By arranging the interlayer slab 3 on the supporting corbel 1 on the frame column 2, there is no need to set a ladder column structure, thereby effectively avoiding the formation of short columns on the frame column 2, helping to reduce the impact of the staircase components on the overall structural rigidity, and improving the seismic performance of the overall structure.
