Description

Technical Field

[0001] This invention belongs to the field of spiral staircase technology, and particularly relates to a prefabricated design structure for an ultra-high spiral staircase. Background Technology

[0002] Spiral staircases, often called spiral staircases or spiral staircases, are typically arranged around a single column. They are popular due to their streamlined, aesthetically pleasing, and space-saving design.

[0003] Chinese Patent (CN201610777988.1) discloses a solid-web, large-section spiral staircase-shaped box girder and its manufacturing method, comprising a large-section spiral base plate, middle and side curved and twisted web plates, and a top small-section strip-shaped spiral cover plate; the spiral base plate is an ultra-wide panel with a spiral curved surface rising upwards; there are four curved and twisted web plates of equal width, which are evenly distributed vertically at equal intervals on the surface of the spiral base plate; the spiral cover plate is embedded between each curved and twisted web plate and its upper surface is flush with the top of each curved and twisted web plate.

[0004] Chinese Patent (CN202210179022.3) discloses a prefabricated cantilevered spiral staircase, comprising several cantilever components, a base component, a platform, several connecting tiles, a pair of handrail bases, and handrail components. The cantilever components are arranged spirally upwards in successive stages, and each can be detachably installed between the base component and the platform. Connecting tiles are detachably connected to the inner ends of the base component and the first cantilever component, as well as between adjacent cantilever components. The outer ends of the base component and the first cantilever component, as well as the outer ends of adjacent cantilever components, are connected by connecting rods. The pair of handrail bases are arranged spirally upwards along the outer and inner walls of the cantilever components, respectively, and the handrail components are disposed on the handrail bases.

[0005] Chinese patent (CN202122511933.5) discloses a column-free spiral staircase, including a rotating and ascending side panel and steps. The bottom thickness of the side panel is greater than the top thickness to form a support beam. The side panel includes multiple side panel segments, each side panel segment including a baffle and a fixing plate that are fixedly connected to each other. The fixing plates of adjacent side panel segments overlap and are screwed together. The steps include multiple connected step structures that can be screwed to the side panel.

[0006] Currently, the installation of column-free spiral staircases requires custom-made curved keels. These curved keels serve as supports for the installation of the treads, which constrains the installation of the spiral staircase. During the installation process, the treads need to be constantly adjusted, making the installation process cumbersome, the structure complex, and the installation efficiency low. Summary of the Invention

[0007] The purpose of this invention is to solve the problem that the installation of column-free spiral staircases requires customized special curved keels, which serve as installation supports for the treads. During the installation process, the treads need to be constantly adjusted, resulting in a complicated installation process, complex structural design, and low installation efficiency. Therefore, this invention proposes a prefabricated design structure for ultra-high spiral staircases.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated design structure for an ultra-high spiral staircase, comprising an upper fixed sleeve, a lower fixed sleeve, multiple treads, multiple protective components, and two handrails. The upper fixed sleeve is fixedly installed on the wall base, and the lower fixed sleeve is located below the upper fixed sleeve and fixedly installed on the ground base. The multiple treads are arranged in a spiral upward arrangement, with adjacent treads overlapping each other and connected by two connecting components. The uppermost tread is inserted into the upper fixed sleeve, and the lowermost tread is inserted into the lower fixed sleeve. The multiple protective components are snapped onto the multiple connecting components, and each protective component corresponds one-to-one with a connecting component. The two handrails connect the multiple protective components.

[0009] As a further description of the above technical solution:

[0010] Two first slots are provided on each side of the pedal, and the first slots are connected to the top surface of the pedal. Two second slots are provided on each side of the pedal, and the second slots are connected to the bottom surface of the pedal. The connector is inserted from one side into the first slot and the second slot of two adjacent pedals.

[0011] As a further description of the above technical solution:

[0012] The lower end of the protective component is provided with a collar, which is snapped onto the connector.

[0013] As a further description of the above technical solution:

[0014] The cross-section of the connector is figure-eight shaped.

[0015] As a further description of the above technical solution:

[0016] The connector has a pin hole at its end.

[0017] As a further description of the above technical solution:

[0018] The surface of the connector is covered with an elastic layer.

[0019] As a further description of the above technical solution:

[0020] The pedal is a rectangular plate.

[0021] As a further description of the above technical solution:

[0022] One end of the pedal is screwed with a first limiting post, which abuts against one side of the pedal located above the pedal. The other end of the pedal is screwed with a second limiting post, which abuts against the other side of the pedal located below the pedal.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] In this invention, by using connectors to connect two adjacent treads, the installation of the treads is completed and mutual constraints between the treads are established. Multiple treads are arranged in a spiral upward pattern and form a whole. This whole is constrained by an upper fixed sleeve and a lower fixed sleeve to form a column-free spiral staircase. The entire installation structure is simple and the installation process is simple and convenient, thereby greatly improving the assembly efficiency of the spiral staircase.

[0035] Please see Figure 1-7This invention provides a technical solution: a prefabricated design structure for an ultra-high spiral staircase, including an upper fixed sleeve 1, a lower fixed sleeve 2, multiple treads 3, multiple protective components 4, and two handrails 5. The upper fixed sleeve 1 is fixedly installed on the wall base, and the lower fixed sleeve 2 is located below the upper fixed sleeve 1 and is fixedly installed on the ground base. The multiple treads 3 are arranged in a spiral upward arrangement, with adjacent treads 3 overlapping each other and connected by two connecting components 6. The uppermost tread 3 is inserted into the upper fixed sleeve 1, and the lowermost tread 3 is inserted into the lower fixed sleeve 2. The multiple protective components 4 are snapped onto the multiple connecting components 6, and the protective components 4 correspond one-to-one with the connecting components 6. The two handrails 5 connect the multiple protective components 4.

[0036] Two first slots 7 are respectively opened on both sides of the pedal 3. The first slots 7 are connected to the top surface of the pedal 3. Two second slots 8 are respectively opened on both sides of the pedal 3. The second slots 8 are connected to the bottom surface of the pedal 3. The connector 6 is inserted from one side into the first slots 7 and the second slots 8 of two adjacent pedals 3, which facilitates the quick establishment of the connection between adjacent pedals 3, so that the pedals 3 are mutually constrained, simplifying the connection structure between pedals 3 and facilitating the quick installation of pedals 3.

[0037] The lower end of the protective component 4 is provided with a collar 9, which is snapped onto the connector 6, facilitating the quick installation of the protective component 4 and greatly improving the installation efficiency of the spiral staircase.

[0038] The cross-section of the connector 6 is figure-eight shaped;

[0039] The end of the connector 6 is provided with a pin hole 10, into which a positioning pin can be inserted to prevent the collar 9 from slipping, thereby ensuring the installation of the protective component 4.

[0040] The surface of the connector 6 is covered with an elastic layer to prevent the connector 6 from slipping.

[0041] The pedal 3 is a rectangular plate;

[0042] One end of the pedal 3 is screwed with a first limiting post 11, which abuts against one side of the pedal 3 located above the pedal 3. The other end of the pedal 3 is screwed with a second limiting post 12, which abuts against the other side of the pedal 3 located below the pedal 3, thereby fully restricting the degree of freedom of the pedal 3.

[0043] Working principle: First, the lower fixing sleeve 2 is fixedly installed on the ground base. The lowest pedal 3 is snapped into the lower fixing sleeve 2. Another pedal 3 is placed on the already installed pedal 3. The connector 6 is inserted from one side into the first slot 7 of one pedal 3 and the second slot 8 of another pedal 3 to complete the connection between two adjacent pedals 3. Multiple pedals 3 are installed in sequence, and the multiple pedals 3 are arranged in a spiral upward arrangement so that multiple pedals 3 form a whole. Next, the first limiting post 11 is screwed onto the pedal 3 and abuts against one side of the pedal 3 located below the pedal 3. The second limiting post 12 is screwed onto the pedal 3 and abuts against the other side of the pedal 3 located above the pedal 3, thereby fully restricting the freedom of movement between the pedals 3. Then, the collar 9 on the protective part 4 is snapped onto the connector 6. More protective parts 4 are installed in sequence so that the protective parts 4 correspond one-to-one with the connector 6. Finally, the handrail 5 is connected to multiple protective parts 4, and a pin is inserted into the pin hole 10 of the connector 6.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
