Description

Technical Field

[0001] This utility model relates to the field of building stair technology, and in particular to an installation structure for a precast concrete staircase for buildings. Background Technology

[0002] Precast stairs are one of the commonly used components in prefabricated buildings. They are produced in component factories and then transported to the construction site for installation. After installation, they can be used as on-site construction passages immediately, which is convenient and quick. In the production of precast stairs, the handrail embedded parts can be embedded in advance, and the anti-slip strips, drip lines and other structures are formed by casting in one go through fixed mold production, reducing the secondary processing of stairs on site. Moreover, precast stairs are of higher quality and better appearance than cast-in-place stairs, with the aesthetic effect of fair-faced concrete. II. Production methods and processes of precast stairs The production methods of precast stairs in component factories are mainly horizontal production and vertical production.

[0003] An investigation revealed a Chinese utility model patent, CN103343596A, disclosing a concrete staircase structure. This structure includes inclined stair slabs and steps, with the steps continuously arranged along the slabs. Each slab has a set of perforated holes along its inclined direction, and each step has perforated holes along its horizontal direction. The slabs and steps are integrated into a single concrete staircase structure. The advantages of this invention are its simple structure, convenient construction, reduced weight of the concrete staircase, reduced material waste, and lower construction costs.

[0004] The aforementioned patent has limitations in functionality when users need to assemble the staircase installation structure. Furthermore, the staircase can only be installed in a fixed manner, which cannot be adjusted according to the size of the space. In addition, the installation structure is not stable enough when users install it, which affects the user's use of the installation structure. Therefore, there is a particular need for a precast concrete staircase installation structure for buildings. Utility Model Content

[0007] A rod is fixedly connected to one side of the fixed docking plate, a collar is fixedly connected to one side of the fixed docking plate, a positioning opening is provided on one side of the collar, a fixing block is fixedly connected to one side of the collar, a nut is fixedly connected to one side of the fixing block, a protective limiting frame is fixedly connected to one side of the collar, and a protective plate is movably connected to one side of the protective limiting frame.

[0008] Preferably, a fixing plate is fixedly connected to one side of the prefabricated staircase installation structure, and the fixing plate is symmetrically arranged with the vertical centerline of the prefabricated staircase installation structure as the axis of symmetry.

[0009] Preferably, the mounting plate has multiple mounting openings.

[0010] Preferably, a pull ring is fixedly connected to one side of the protective plate, and the pull ring is connected between the protective plate and the protective limiting frame.

[0011] Preferably, the fixed docking plate has a splicing opening on one side, and the size of the splicing opening and the installation fixed support rod are matched.

[0012] Preferably, the nut is connected between a fixing block and a collar, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0013] Preferably, a threaded rod is movably connected to one side of the nut, and the threaded rod is connected between the nut and the fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The clever design of components such as positioning sleeves, mounting support rods, fixing docking plates, and plug rods makes the installation process of prefabricated stairs more convenient. The plug-in openings on the positioning sleeves and the splicing openings on the fixing docking plates ensure precise alignment between components, while the movable connection of the mounting support rods provides adjustment space during installation, ensuring the stability of the installation. In addition, the multiple installation openings on the fixing mounting plates further enhance the flexibility and stability of the installation.

[0016] The combination of protective limit frame and protective plate design effectively prevents the stairs from accidentally sliding or being damaged during use, improving safety. At the same time, the use of nuts and threaded rods allows the installation structure to be finely adjusted after installation to adapt to the needs of different scenarios, enhancing the practicality and adaptability of the structure.
