Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated building structures, and more specifically, it relates to a prefabricated building staircase structure that is easy to install. Background Technology

[0002] Staircases are vertical transportation facilities in buildings that connect different floors. They consist of stair flights, platforms, handrails, etc. According to materials, they can be classified as reinforced concrete staircases and steel staircases; according to form, they can be classified as straight staircases, L-shaped staircases, U-shaped staircases, spiral staircases, etc. In the context of the development of building industrialization and prefabricated buildings, prefabricated staircases are widely used due to their advantages such as high construction efficiency and controllable quality. Traditional prefabricated assembled staircase structures are usually installed by on-site hoisting.

[0003] Based on the above, the connection nodes of existing traditional precast stairs are complex and unreliable. Some stair structures use wet connections (such as cast-in-place concrete nodes), which require waiting for concrete curing. This not only increases the construction process but may also affect the overall structural safety due to unstable on-site pouring quality. Dry connection methods (such as bolt connections) have problems such as complex node construction and stress concentration, which can easily lead to loosening during long-term use. Traditional precast stairs are mostly integral components with large volume and weight, which are easily damaged during transportation. Moreover, they require the cooperation of large machinery during hoisting, which places high demands on the construction site conditions and increases transportation and installation costs. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an easy-to-install prefabricated building staircase structure. This solves the issues of complex and unreliable connection nodes in traditional prefabricated staircases, where some staircase structures use wet connections (such as cast-in-place concrete joints), requiring waiting for concrete curing. This not only increases construction steps but may also affect the overall structural safety due to unstable on-site casting quality. Dry connection methods (such as bolted connections) suffer from complex node structures and stress concentration, making them prone to loosening over long-term use. Traditional prefabricated staircases are mostly integral components, large in size and weight, easily damaged during transportation, and require large machinery for hoisting, placing high demands on construction site conditions and increasing transportation and installation costs.

[0013] This utility model provides a prefabricated assembled building staircase structure that is easy to install, and has the following beneficial effects:

[0014] This utility model achieves the following optimization effects by providing a load-bearing support, a load-bearing block, a connecting column, and a load-bearing frame:

[0015] Prefabricated structure: The prefabricated modular structure allows the entire staircase to be disassembled into independent components, making the prefabricated staircase structure easy to transport and install, reducing the use of large machinery, lowering the requirements for construction site conditions, and reducing transportation and installation costs.

[0016] Improved positioning and fixing accuracy: Through the cooperation of the support groove and the installation bolt, the load-bearing support can be accurately fixed in the designated position of the wall. With the cooperation of the load-bearing clip, the load-bearing support frame is rigidly positioned to ensure the verticality and horizontality of the overall assembly and avoid uneven stress caused by installation deviation.

[0017] Adaptability and flexible adjustment: The load-bearing support frame can be extended in length or adjusted in angle by assembling supports, which can not only adapt to different wall spacing requirements, but also be customized for the width and tilt angle of stair treads, solving the problem of insufficient versatility of traditional fixed brackets.

[0018] Multi-dimensional limiting and locking mechanism: The locking support and the threaded clamp in the installation opening form a two-way limiting mechanism to lock the stair treads axially and radially; the anti-slip texture on the surface of the anti-slip treads enhances the friction of the tread surface, providing double protection for safety during use;

[0019] Linked load-bearing and stability enhancement: The connecting support is fitted with a groove on the outside of the threaded support and locked by the threaded pressure block, so that multiple sets of load-bearing supports form a force-linked structure, distributing the single-point load to the overall frame, which significantly improves the overall overturning resistance of the staircase.

[0020] Reinforcement and Deformation Resistance Design: The reinforced support column cooperates with the reinforced connecting column through the threaded support groove to form lateral support for the threaded side column, constructing a triangular stable structure, effectively suppressing the lateral deformation of the connecting support column under heavy load, and ensuring the long-term reliability of the multi-support linkage system.
