Description

Technical Field

[0001] This application belongs to the field of staircase technology, and in particular relates to a precast concrete staircase. Background Technology

[0002] In recent years, with the development of the construction industry, more and more people are choosing PC (precast concrete) components when building houses. Compared with traditional cast-in-place concrete, the construction environment of PC components is in a PC factory, which is safer than on-site construction. Furthermore, the prefabricated dimensions can significantly improve the installation speed and construction progress. At the same time, the amount of on-site work is significantly reduced when using PC components, which can effectively reduce dust and noise pollution.

[0003] Precast concrete stairs can be precast components with direct, integral support, or they can consist of individual precast treads. Multiple treads can form a staircase, and the treads can be made of traditional concrete or lightweight concrete. Lightweight concrete stair treads are functional components made primarily of lightweight concrete. Lightweight concrete can serve as the base layer, with a decorative layer of wood, stone, or slab paving on the surface. However, precast concrete stairs made of multiple treads still have structural strength issues during installation and require improvement. Summary of the Invention

[0004] The purpose of this application is to provide a precast concrete staircase that can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a precast concrete staircase, comprising:

[0006] The supporting beam has one end connected to the ground and the other end extending upward at an angle.

[0007] The pedal body is mounted on the support beam and is made of lightweight concrete;

[0008] A support component, mounted on a support beam and connected to the pedal body, is used to fix the pedal body.

[0009] The system includes multiple pedal bodies evenly distributed along the extension direction of the support beam. One end of the support beam is fixed to the ground, and the other end is fixed to the second floor of the building, forming an inclined structure. Multiple pedal bodies are installed and evenly distributed along the extension direction of the support beam.

[0010] Furthermore, the support member includes:

[0011] The first plate, the top of which is connected to the pedal body;

[0012] The second plate is connected to the pedal body at the top and to the support beam on the side by screws.

[0013] The first plate and the second plate are an integral structure.

[0014] Furthermore, the support member also includes a metal plate disposed at the bottom of the pedal body, the bottom of the metal plate being fixedly connected to the first plate and the second plate. The bottom of the metal plate is welded to the first plate and the second plate.

[0015] Furthermore, the angle between the first plate and the second plate is 90°, forming an "L"-shaped structure. Reinforcing ribs are also installed between the first plate and the second plate.

[0016] Furthermore, the metal plate has multiple positioning holes for fasteners to pass through, and the metal plate is fixed to the bottom of the pedal body by fasteners. The fasteners are screws.

[0017] Furthermore, each pedal body has two support members at its bottom, which are symmetrically arranged on both sides of the pedal.

[0018] Furthermore, the support beam is provided with multiple support protrusions, and the pedal body is fixed to the support protrusions. The support protrusions and the support beam are an integral structure.

[0019] Furthermore, fixing plates are provided at both ends of the support beam, and the support beam is fixed to the ground and other buildings through the fixing plates. It is also fixed with screws and bolts.

[0020] The beneficial effects of this application are:

[0021] 1. By installing the support components, fixing them to the support beam and connecting them to the tread body, the support components can provide additional fixation and support for the tread body. Compared with the traditional precast concrete stairs that are simply composed of multiple treads, this can effectively enhance the overall structural strength of the stairs and improve the stability and safety of the stairs.

[0022] 2. The treads are made of lightweight concrete as the core material, which makes the entire staircase relatively light, making it easy to transport and install. Lightweight concrete can also be used as a base layer, and the surface can be covered with decorative layers such as wood, stone or rock slabs. While ensuring the structural performance of the staircase, it meets diverse decorative needs and improves the overall aesthetics of the staircase.

[0023] 3. The pedal body is equipped with multiple pedals that are evenly distributed along the extension direction of the support beam. The modular design of the prefabricated pedals facilitates prefabrication, effectively improving production efficiency and reducing production costs. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The precast concrete staircase provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown in the figure, this application provides a precast concrete staircase, including:

[0033] The support beam 100 has one end connected to the ground and the other end extending upward at an angle.

[0034] The pedal body 200 is mounted on the support beam 100 and is made of lightweight concrete;

[0035] Support member 300 is disposed on support beam 100 and connected to pedal body 200 for fixing pedal body 200;

[0036] The pedal body 200 is provided with multiple pedals that are evenly distributed along the extension direction of the support beam 100.

[0037] In some embodiments of this application, such as Figure 1 As shown, in this type of precast concrete staircase, one end of the support beam 100 is fixed to the ground, and the other end is fixed to the second floor of the building, forming an inclined structure that provides support. The support member 300 is installed and fixed to the support beam 100, connecting to the tread body 200, providing additional fixation and support for the tread body 200. Compared to traditional precast concrete staircases that are simply composed of multiple treads, this effectively enhances the overall structural strength of the staircase, improving its stability and safety. Furthermore, the tread body 200 is made of lightweight concrete, which has low density and light weight, making the entire staircase relatively lightweight and easy to transport and install. Lightweight concrete can also be used as a base layer, and the surface can be covered with decorative layers such as wood, stone, or slabs, ensuring the structural performance of the staircase while meeting diverse decorative needs and improving its overall aesthetics.

[0038] Furthermore, multiple prefabricated pedal bodies 200 are installed and evenly distributed along the extension direction of the support beam 100. The modular design of the prefabricated pedals facilitates prefabrication, effectively improving production efficiency and reducing production costs. During installation, each prefabricated pedal body 200 is simply installed sequentially on the support beam 100, making the construction process relatively simple and quick, thereby shortening the construction cycle.

[0039] Furthermore, fixing plates 120 are provided at both ends of the support beam 100, and the support beam 100 is fixed to the ground and other building components via the fixing plates 120. It is also fixed using screws and bolts.

[0040] Fixing plates 120 are installed at both ends of the support beam 100, and fixed to the ground and other building structures with screws and other fasteners to form a stable connection point, ensuring the structural stability of the staircase during long-term use. The fixing plates 120 increase the contact area with the ground and other buildings, thereby increasing the area for installing screws and improving the fixing effect.

[0041] Example 2:

[0042] This application provides a precast concrete staircase, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0043] like Figures 1 to 3 As shown, the support member 300 includes:

[0044] The first plate 310, the top of which is connected to the pedal body 200;

[0045] The second plate 320 is connected to the pedal body 200 at its top and to the support beam 100 on its side by screws.

[0046] The first plate 310 and the second plate 320 are an integral structure.

[0047] In this embodiment, the first plate 310 and the second plate 320 are an integral structure, allowing the support member 300 to function as a whole under load. This avoids structural failure caused by loosening or breakage of the connection points and allows for prefabrication, enabling direct transport to the construction site for installation and improving production efficiency. Furthermore, when bearing the load on the stair treads, the force can be more evenly distributed to the support beam 100, enhancing the overall stability of the staircase structure.

[0048] The top of the first plate 310 is connected to the tread body 200, and the side of the second plate 320 is connected to the support beam 100 by screws, forming a support from the tread to the support member 300 and a fixation from the support member 300 to the support beam 100, further enhancing the connection strength between the tread body 200 and the support beam 100. Furthermore, since the support member 300 and the tread body 200 are independent modules in the staircase structure, if they are damaged or need replacement during use, they can be replaced individually without large-scale disassembly and reconstruction of the entire staircase structure, improving the efficiency of staircase maintenance and replacement.

[0049] Furthermore, the included angle between the first plate 310 and the second plate 320 is 90°.

[0050] The first plate 310 and the second plate 320 form an "L" shape with an angle of 90°, making the support member 300 more stable under stress. The 90° angle allows for better coordination with the support beam 100 and the pedal body 200. Furthermore, reinforcing ribs are installed between the first plate 310 and the second plate 320 to further enhance structural strength.

[0051] Example 3:

[0052] This application provides a precast concrete staircase, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0053] like Figures 1 to 3 As shown, the support member 300 also includes a metal plate 330 disposed at the bottom of the pedal body 200, and the bottom of the metal plate 330 is fixedly connected to the first plate 310 and the second plate 320.

[0054] In this embodiment, the metal plate 330, as a high-strength material, can effectively bear and distribute the load borne by the staircase, significantly improving the load-bearing capacity of the stair slab. In this application, the installation method of the metal plate 330 is similar to the principle of the steel plate bonding reinforcement method. By fixing the metal plate 330 to the stress-bearing bottom surface of the stair slab, the mechanical properties of the stair slab, such as bending and shear resistance, can be directly enhanced, thereby effectively improving its load-bearing capacity.

[0055] Meanwhile, the bottom of the metal plate 330 is fixedly connected to the first plate 310 and the second plate 320. Welding can be used to form a more stable overall structure, which not only enhances the stability of the support 300 itself, but also connects the tread body 200 and the support beam 100 more tightly through the metal plate 330, thereby improving the stability of the entire staircase structure.

[0056] Furthermore, the metal plate 330 has multiple positioning holes 331 for fasteners to pass through, and the metal plate 330 is fixed to the bottom of the pedal body 200 by fasteners.

[0057] The positioning holes 331 on the metal plate 330, when engaged with fasteners, allow for secure fixing to the tread body 200, improving the fixation effect between the metal plate 330 and the tread body 200 and ensuring a tight connection. Screws can be used as the fasteners. By firmly fixing the metal plate 330 to the bottom of the tread body 200 with fasteners, the metal plate 330 can more effectively bear and distribute the load, significantly improving the load-bearing capacity of the stair tread.

[0058] Example 4:

[0059] This application provides a precast concrete staircase, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0060] like Figures 1 to 3 As shown, each pedal body 200 has two support members 300 at its bottom, and the two support members 300 are symmetrically arranged on both sides of the pedal.

[0061] In this embodiment, each tread body 200 is equipped with two symmetrical support members 300 at its bottom, forming a stable two-point support structure. This effectively distributes the load borne by the tread, avoiding structural imbalance or deformation that may occur with single-point support, and significantly improving the overall stability of the staircase. Simultaneously, the symmetrical support members 300 enhance the tread's ability to resist lateral forces (such as the lateral force exerted by people walking), reducing the risk of tread swaying or tilting, and further improving the safety of the staircase.

[0062] In addition, the design of the symmetrical support component 300 makes the installation process of each pedal more standardized and modular, allowing construction workers to install according to a unified process and standard, thus improving construction efficiency and quality.

[0063] Example 5:

[0064] This application provides a precast concrete staircase, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0065] like Figures 1 to 3 As shown, the support beam 100 is provided with multiple support protrusions 110, and the pedal body 200 is fixed on the support protrusions 110.

[0066] In this embodiment, the support protrusion 110 and the support beam 100 are an integral structure, which can provide additional support for the installation of the pedal body 200, further distribute the load transmitted by the pedal, and improve the load-bearing capacity. At the same time, the support protrusion 110 can provide positioning for the installation of the pedal body 200, enabling construction personnel to quickly install the pedal body 200 and improve installation accuracy.
