Description

Technical Field

[0001] This utility model relates to the field of building structures, and in particular to a modular prefabricated cross staircase. Background Technology

[0002] In traditional building construction, staircases, as key structural components connecting different floors, are often installed by directly fixing the intersecting staircase structure to the existing building structure. This installation method has significant limitations, primarily in the extreme inconvenience of dismantling the staircase. Because the staircase is tightly connected to the building structure, if it needs to be moved or removed, construction workers must spend a considerable amount of time and effort severing the connection points between the staircase and the building structure. This not only increases the difficulty of construction but may also damage the original building structure, affecting the building's integrity and stability.

[0003] In recent years, the rise of modular prefabricated building technology has provided new ideas for staircase design. However, existing solutions still have shortcomings for the special structure of intersecting staircases: firstly, most modular staircases have not been optimized for intersecting support structures, resulting in insufficient overall stability; secondly, the connection between treads and support beams mostly relies on welding or gluing, which can easily damage components during disassembly, making it difficult to achieve true reversible assembly.

[0004] This utility model aims to provide a modular prefabricated cross staircase. By adding stair columns, the overall structure of the staircase is separated from the existing building structure, thereby achieving convenient installation and flexible disassembly of the staircase, providing a new solution for modern building construction and space utilization. Utility Model Content

[0005] The purpose of this utility model is to provide a modular, prefabricated cross staircase, which adds stair columns so that the overall structure of the staircase is separated from the existing building structure, making it convenient for subsequent movement and disassembly.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a modular prefabricated cross staircase, including a platform beam, stair columns, and a cross-supported staircase structure. The stair columns and the platform beam are assembled together to form a support frame. The platform beam is connected between two stair columns in the transverse direction. The cross-supported staircase structure is connected between two opposite platform beams. One side of the cross-supported staircase structure is close to a matching existing building structure, thereby forming a continuous up-and-down pedestrian passage.

[0008] Preferably, the cross-supported staircase structure includes inclined stair beams, treads, and U-shaped connectors. The two ends of the inclined stair beams are respectively fixedly connected to the U-shaped connectors, and the inclined stair beams are connected to two opposite platform beams through the U-shaped connectors. Treads are used to limit the movement between the two opposite inclined stair beams.

[0009] Preferably, a step plate connector is fixedly connected to one side of each inclined ladder beam. The step plate connector is U-shaped, and a limiting plate is fixedly connected to the bottom of the step plate. The limiting plate is embedded in the U-shaped groove of the step plate connector. The two end faces of the step plate abut against the opposite faces of the two inclined ladder beams respectively. The position and specifications of the step plate connector, the step plate, and the limiting plate are matched.

[0010] Preferably, the inclined ladder beam includes inclined sections and gentle sections connected together, the step plates are staggered on the inclined sections, and the step plates are closely arranged on the gentle sections to form a walking platform.

[0011] Preferably, the inclined ladder beam includes a first inclined ladder beam and a second inclined ladder beam. The two first inclined ladder beams and several steps form an upper inclined support arm group, and the two second inclined ladder beams and several steps form a lower inclined support arm group. The lower inclined support arm group and the upper inclined support arm group are staggered in the vertical direction.

[0012] Preferably, one end of the first inclined ladder beam is fixed to the platform beam, and the other end of the first inclined ladder beam extends obliquely upward and connects to the platform beam on the other side; one end of the second inclined ladder beam is fixed to the platform beam, and the other end of the second inclined ladder beam extends obliquely downward and connects to the platform beam on the other side.

[0013] Preferably, the U-shaped connector has a through hole, and the U-shaped connector and the platform beam are connected together by bolts.

[0014] Preferably, it includes four sets of ladder columns, each set of ladder columns being connected together in the vertical direction by ladder column connectors and bolt assemblies.

[0015] Preferably, the bottom of the ladder column is bolted to a support column, which is connected to the sleeper.

The step plate connector 7 matches the position and specifications of the step plate 4 and the limiting plate 41.

[0035] Specifically, the end of the step plate connector 7 is welded to the side of the inclined ladder beam 3. The lower inclined support arm assembly and the upper inclined support arm assembly respectively support the step plate with the help of two step plate connectors 7, thereby facilitating people to walk on the step plate.

[0036] like Figure 1 As shown, the inclined ladder beam 3 includes an inclined section and a gentle section connected together, and the step plates 4 are staggered on the inclined section. The step plates 4 are closely arranged on the gentle section to form a walking platform.
