Description

Technical Field

[0001] This utility model relates to the field of staircase technology, and in particular to a staircase structure that is easy to install. Background Technology

[0002] In the field of building decoration, staircases are vital passageways connecting different floors. Traditional staircase structures typically employ monolithic cast-in-place concrete, a method plagued by long construction periods and complex installation processes. Installation involves a series of tedious procedures, including formwork erection, concrete pouring, and curing, consuming significant manpower and time, and making subsequent maintenance and replacement extremely inconvenient. With the development of the building decoration industry, higher demands are placed on the ease of installation, structural stability, and functionality of staircase structures; therefore, there is an urgent need for a staircase structure that is easy to install. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the need to erect many formworks during stair pouring, which results in high costs and a relatively fixed overall structure that is inconvenient for disassembly, installation, replacement, and maintenance. Therefore, this utility model proposes a stair structure that is easy to install.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-install staircase structure includes a concrete main body with multiple step units installed on it. Each step unit includes a horizontal tread and a vertical support plate. One end of the horizontal tread is fixed to the concrete main body via a first connector, and the other end of the horizontal tread is fixedly connected to the upper end of the inner side of the vertical support plate via an angle bracket. The lower end of the inner side of the vertical support plate is fixed to the concrete main body via a second connector, and a light strip is fixed to the bottom side of the other end of the horizontal tread.

[0005] Furthermore, side decorative panels are fixed to both sides of the horizontal treads and vertical support plates. The side decorative panels not only enhance the aesthetics of the staircase but also provide some protection for the horizontal treads and vertical support plates.

[0006] Furthermore, several anti-slip strips are fixed on the horizontal tread of the concrete main body. The anti-slip strips can effectively increase the friction of the stair surface, improve safety during use, and prevent pedestrians from slipping.

[0007] Furthermore, an edge sealing strip is installed between the horizontal tread fixed to the top of the concrete structure and the concrete structure. The edge sealing strip can seal and decorate the edges of the stairs, making the stairs more beautiful and neat overall.

[0008] Furthermore, both the first and second connecting components are hollow right-angled triangular plate structures. The first connecting component has equidistantly arranged first mounting through holes on both the surface containing its long right-angled side and its hypotenuse. Similarly, the second connecting component has equidistantly arranged second mounting through holes on both the surface containing its long right-angled side and its hypotenuse. This structural design facilitates the fixed connection of the first and second connecting components to the concrete main body, the horizontal tread, and the vertical support plate, while the hollow structure reduces the overall weight.

[0009] Furthermore, the first mounting through hole is a circular hole, and the second mounting through hole includes interconnected rectangular and circular hole segments. This design allows the second connector to have a certain degree of adjustment during installation, enabling it to better adapt to different installation environments and improving installation accuracy and convenience.

[0010] Furthermore, the first connecting piece and the second connecting piece are respectively connected to the concrete main body and the horizontal tread / vertical support plate by expansion bolts. The expansion bolt connection method is simple and reliable, and can ensure the stability of the staircase structure.

[0011] Furthermore, the horizontal treadle is made of a 20mm thick composite board, which has good strength and durability, and is relatively lightweight, making it easy to install and transport.

[0012] The staircase structure proposed in this utility model is easy to install and has the following advantages: 1. This utility model, by designing the step unit as a detachable horizontal tread and vertical support plate, and using a first connector, a second connector, and corner brackets for connection and fixation, abandons the traditional method of integral concrete pouring, greatly simplifying the staircase installation process, shortening the construction cycle, and reducing labor and time costs. During installation, it is only necessary to connect and fix the components in sequence, without the need for complex formwork construction and concrete pouring procedures.

[0013] 2. Because the components are detachably connected, when a part of the staircase is damaged, it can be repaired and replaced quickly and easily without having to make large-scale modifications to the entire staircase, thus improving the convenience of later maintenance.

[0014] 3. The LED strip fixed to the bottom of the end of the horizontal tread can provide illumination at night or in low-light environments, increasing the safety and convenience of using the stairs.

[0015] 4. The design of the decorative panels on both sides of the horizontal treads and vertical support plates, the anti-slip strips on the horizontal treads, and the sealing strip between the top horizontal tread and the concrete main body not only enhances the aesthetics of the staircase, but also further improves the safety and comfort of using the staircase.

[0016] 5. The special structural design of the first and second connecting parts, as well as the design of the installation through holes, makes the installation of the staircase structure more flexible and accurate, adaptable to different installation environments and needs, and ensures the stability of the staircase structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-5 As shown, an easy-to-install staircase structure includes a concrete body 1, on which multiple step units 2 are installed. Each step unit 2 includes a horizontal tread 3 and a vertical support plate 4. One end of the horizontal tread 3 is fixed to the concrete body 1 by a first connector 5, and the other end of the horizontal tread 3 is fixedly connected to the upper end of the inner side of the vertical support plate 4 by a corner bracket 6. The lower end of the inner side of the vertical support plate 4 is fixed to the concrete body 1 by a second connector 7. A light strip 8 is fixed to the bottom side of the other end of the horizontal tread 3.

[0021] Both sides of the horizontal tread 3 and the vertical support plate 4 are fixed with side decorative panels 9. The side decorative panels 9 not only enhance the aesthetics of the staircase, but also provide a certain degree of protection for the horizontal tread 3 and the vertical support plate 4.

[0022] Several anti-slip strips 10 are fixed on the horizontal tread 3 of the concrete main body 1. The anti-slip strips 10 can effectively increase the friction of the stair surface, improve safety during use, and prevent pedestrians from slipping.

[0023] An edge sealing strip 11 is installed between the horizontal tread 3 fixed at the top of the concrete main body 1 and the concrete main body 1. The edge sealing strip 11 can seal and decorate the edge of the staircase, making the staircase more beautiful and neat overall.

[0024] Both the first connecting piece 5 and the second connecting piece 7 are hollow right-angled triangular plate structures. The first connecting piece 5 has equidistantly arranged first mounting through holes 12 on both the plate surface containing its long right-angled side and its hypotenuse. Similarly, the second connecting piece 7 has equidistantly arranged second mounting through holes 13 on both the plate surface containing its long right-angled side and its hypotenuse. This structural design facilitates the fixed connection of the first connecting piece 5 and the second connecting piece 7 to the concrete main body 1, the horizontal tread 3, and the vertical support plate 4, and the hollow structure reduces the overall weight.

[0025] The first mounting through hole 12 is a circular hole, and the second mounting through hole 13 includes interconnected rectangular and circular segments. This design allows the second connector 7 to have a certain adjustment range during installation, enabling it to better adapt to different installation environments and improve the accuracy and convenience of installation.

[0026] The first connecting piece 5 and the second connecting piece 7 are respectively connected to the concrete main body 1 and the horizontal tread 3 / vertical support plate 4 by expansion bolts 14. The expansion bolt 14 connection method is simple and reliable, which can ensure the stability of the stair structure.

[0027] The horizontal pedal 3 is a 20mm thick composite board. The composite board has good strength and durability, and is relatively lightweight, making it easy to install and transport.

[0028] This utility model discloses a staircase structure that is easy to install. During installation, the installation positions of the step units 2 are first determined on the concrete main body 1 according to design requirements. The first connecting piece 5 is fixed to one end of the horizontal tread 3 on the concrete main body 1 using expansion bolts 14. The surface of the first connecting piece 5 with its long right-angled side is flush with the concrete main body 1, and it is fixed using expansion bolts 14 through the first mounting through hole 12. Then, one end of the horizontal tread 3 is connected and fixed to the first connecting piece 5. Next, the other end of the horizontal tread 3 is fixed to the upper end of the inner side of the vertical support plate 4 using angle brackets 6. Then, the second connecting piece 7 is fixed to the lower end of the inner side of the vertical support plate 4 on the concrete main body 1 using expansion bolts 14. The surface of the second connecting piece 7 with its long right-angled side is flush with the concrete main body 1, and it is fixed using expansion bolts 14 through the second mounting through hole 13. Finally, the lower end of the inner side of the vertical support plate 4 is connected and fixed to the second connecting piece 7. Multiple step units 2 are installed sequentially according to the above steps to complete the construction of the main staircase structure. Next, light strip 8 is installed on the bottom side of the other end of the horizontal tread 3, side decorative panels 9 are installed on both sides of the horizontal tread 3 and the vertical support plate 4, anti-slip strip 10 is fixed on the horizontal tread 3, and edge sealing strip 11 is installed between the horizontal tread 3 at the top of the concrete body 1 and the concrete body 1, thus completing the installation of the entire staircase structure.

[0029] During use, the light strip 8 provides illumination at night, making it easier for pedestrians to go up and down the stairs; the anti-slip strip 10 increases the friction on the surface of the treads, preventing pedestrians from slipping; the side decorative panel 9 and the edge sealing strip 11 enhance the aesthetics and safety of the stairs.
