Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of assembled stairs, and in particular relates to an assembled staircase with a sliding clamping structure. Background Art
[0002] The assembly and installation of prefabricated stairs may also be restricted by construction site conditions. If the construction site is small and crowded, and workers' operations are restricted, then the installation of prefabricated stairs will become very difficult, which may lead to extended construction time, increased manpower and material costs, and adversely affect the construction progress. The conventional response method is to evaluate the construction site conditions in advance and make necessary preparations to ensure the smooth installation of prefabricated stairs. However, these methods also have some disadvantages. For example, the advance assessment of construction site conditions may require additional resource investment, which increases the complexity of planning and resource scheduling. In summary, prefabricated stairs have the disadvantage of being restricted by the construction site. Although conventional response methods can alleviate these problems, there are also certain disadvantages. Therefore, we hope to design a prefabricated staircase with a new structure to solve this problem. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide an assembled staircase with a sliding card structure to solve the problems raised in the above-mentioned background technology.
[0004] The utility model is realized by the following technical scheme: an assembled staircase with a sliding clamping structure, comprising: an assembly frame and a staircase assembly, a plurality of staircase assemblies installed in sequence are movably clamped between two assembly frames, and the assembly frame comprises a side panel frame and a handrail;
[0005] A handrail is welded on the upper side of each side frame, and the stair assembly includes a stair board, a first plug board and a second plug board, and a first plug board is welded on the left front side, the left rear side of the upper end of the stair board and the front side and the right rear side of the upper end;
[0006] A second plug plate is welded to the left rear side and the right rear side of the front end of the stair slab respectively through a connecting plate.
[0007] As a preferred embodiment, multiple groups of insert tubes 1 are welded to one side of the side panel frame close to the stair board, and the heights of the two insert tubes 1 in the same group are flush. The structure of insert tube 1 is the same as that of insert tube 2. The arrangement of insert tube 1 and insert tube 2, in conjunction with insert plate 1 and insert plate 2, allows multiple stair boards to be slidably mounted between the two side panel frames in sequence, greatly reducing the difficulty of assembling the entire assembled staircase, even in a small space.
[0008] As a preferred embodiment, the insert tube 1 is formed with a pin hole 1 through the side of the side plate frame on the side close to the stair plate, and an insert cavity 1 is formed downward on the upper side of the insert tube 1;
[0009] The structure, size and distribution position of the insert cavity 1 are matched with those of the insert plate 1. The insert plate 1 is penetrated from left to right to form a pin hole 2, and the axis of the pin hole 1 is colinear with the axis of the pin hole 2.
[0010] As a preferred embodiment, a second insertion cavity is downwardly opened at the upper end of the second insertion tube, and the structure, size and distribution position of the second insertion cavity are matched with the structure, size and distribution position of the second insertion plate.
[0011] As a preferred embodiment, the stair board includes a vertical board, a horizontal board and a limit plate. The upper end of the vertical board and the front end of the horizontal board are integrally arranged, and the upper end of the vertical board and the front end of the horizontal board are arranged at a ninety-degree angle. The arrangement of the stair boards and multiple stair boards that can be assembled in sequence not only reduces the difficulty of transporting the entire assembled stairs, but also reduces the difficulty of assembly on site later.
[0012] As a preferred embodiment, a limiting plate is integrally provided at the rear end of the horizontal plate, the lower end of the limiting plate is arranged at a 90-degree angle with the rear end of the horizontal plate, and the height of the limiting plate is one fifth of the height of the vertical plate.
[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by welding multiple groups of flush plug-in tubes 1 and plug-in tubes 2 corresponding to the plug-in plates 2 on the side plate frame, the user can slide and clamp the staircase board into the plug-in tubes 1 and 2 according to the needs, even if the fixing pins are not used to fix it, it can have a high use strength and will not fall off easily, so that the entire assembled staircase can be quickly disassembled and assembled, and there is no need to assemble or weld it in advance and transport it to the site for installation. It can be directly installed on site, and even if the site is small, it will not affect the assembly of the entire assembled staircase, and the detachable structure also greatly reduces the difficulty of transportation;
[0014] To set up the stair assembly, align the four plug plates 1 and the two plug plates 2 on the first stair board with the plug tubes 1 and 2 at the lower ends of the two side panel frames, and then press the entire stair board downward so that the plug plate 1 is inserted into the plug tube 1. At the same time, the plug plate 2 is inserted into the plug tube 2. After the plug plates 1 and 2 slide to the maximum stroke position, the lower surface of the stair board abuts against the upper side of the plug tube 1, and the entire stair board is arranged as a whole, which has a high clamping strength. When the second bare board is installed in sequence, the vertical plate on its lower side abuts against the limit plate on the upper end of the first stair board, and they limit each other, which further improves the stability of the stair board after assembly. Multiple stair boards that can be assembled in sequence not only reduce the transportation difficulty of the entire assembled staircase, but also reduce the difficulty of its later on-site assembly.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 4 The utility model provides a technical solution: an assembled staircase with a sliding clamping structure, comprising: an assembly frame 100 and a staircase assembly 200, a plurality of staircase assemblies 200 installed in sequence are movably clamped between two assembly frames 100, and the assembly frame 100 comprises a side panel frame 110 and a handrail 120;
[0024] Each side frame 110 is welded with a handrail 120 on its upper side. The staircase assembly 200 includes a staircase board 210, a first plug board 230 and a second plug board 220. The left front side, the left rear side, the front side and the right rear side of the upper end of the staircase board 210 are respectively welded with a first plug board 230;
[0025] A second plug plate 220 is welded to the left rear side and the right rear side of the front end of the stair tread 210 through a connecting plate.
[0026] See also Figure 1 to Figure 2 A plurality of groups of insert tubes 111 are welded to one side of the side panel frame 110 close to the stair tread 210, and the heights of the two insert tubes 111 in the same group are flush, and the structure of the insert tube 111 is the same as the structure of the insert tube 2 112. The arrangement of the insert tube 111 and the insert tube 2 112, in conjunction with the insert plate 1 230 and the insert plate 220, allows the plurality of stair treads 210 to be slidably mounted between the two side panel frames 110 in sequence, greatly reducing the difficulty of assembling the entire assembled staircase, even in a narrow space.
[0027] The insert tube 111 is formed with a pin hole 1 on one side of the side plate frame 110 near the stair plate 210, and an insert cavity 1 is formed downward on the upper side of the insert tube 111;
[0028] The structure, size and distribution position of the insertion cavity 1 are matched with those of the insertion plate 1 230. The insertion plate 1 230 is penetrated from left to right to form a pin hole 2, and the axis of the pin hole 1 is colinear with the axis of the pin hole 2.
[0029] A second insertion cavity is downwardly opened at the upper end of the second insertion tube 112 , and the structure, size and distribution position of the second insertion cavity are matched with those of the second insertion plate 220 .
[0030] As the first embodiment of the utility model, by welding a plurality of groups of flush plug-in tubes 1 111 and plug-in tubes 2 112 corresponding to the plug-in plates 220 on the side panel frame 110, in actual use, the user can slide and clamp the stair board 210 into the inside of the plug-in tubes 1 111 and 112 through the plug-in plates 1 230 and 220 as needed. Even if the fixing pins are not used to fix it, it can still have high strength of use and will not fall off easily. This allows the entire assembled staircase to be quickly disassembled and assembled, and there is no need for prior assembly or welding and transportation to on-site installation. It can be directly installed on-site, and even if the site is small, it will not affect the assembly of the entire assembled staircase. In addition, the detachable structure also greatly reduces the difficulty of transportation.
[0031] See also Figures 1 to 4The stair tread 210 includes a vertical plate 211, a horizontal plate 212 and a limit plate 213. The upper end of the vertical plate 211 and the front end of the horizontal plate 212 are integrally arranged, and the upper end of the vertical plate 211 and the front end of the horizontal plate 212 are arranged at a ninety-degree angle. The arrangement of the stair tread 210 and multiple stair treads 210 that can be assembled in sequence not only reduce the transportation difficulty of the entire assembled staircase, but also reduce the difficulty of its later on-site assembly.
[0032] A limiting plate 213 is integrally provided at the rear end of the horizontal plate 212 . The lower end of the limiting plate 213 is arranged at a 90-degree angle with the rear end of the horizontal plate 212 . The height of the limiting plate 213 is one fifth of the height of the vertical plate 211 .
[0033] As a second embodiment of the present invention, based on the above-mentioned first embodiment, in actual use, first align the four plug plates 1 230 and the two plug plates 220 on the first stair tread 210 with the plug tubes 1 111 and 112 at the lower ends of the two side frame frames 110, and then press the entire stair tread 210 downward so that the plug plate 1 230 is inserted into the plug tube 1 111, and at the same time, the plug plate 220 is inserted into the plug tube 2 112 (in actual use, the positions of the plug plates 1 230 and the plug plates 2 220 are precisely aligned with the plug tubes 1 111 and 112, and have uniform sizes, and there will be no misalignment between any stair tread 210 and the plug tubes 1 111 and 112 at different positions). After the second stair tread 210 has slid to the maximum stroke position, the lower surface of the stair tread 210 abuts against the upper side of the insert cylinder 111, and the entire stair tread 210 is arranged in an integrated manner, with a high clamping strength. When the second stair tread 210 is installed in sequence, the vertical plate 211 on its lower side abuts against the limiting plate 213 at the upper end of the first stair tread 210, and they limit each other, further improving the stability of the stair tread 210 after assembly. Multiple stair treads 210 that can be assembled in sequence not only reduce the difficulty of transporting the entire assembled staircase, but also reduce the difficulty of assembly on site in the later stage (after the above-mentioned stair tread 210 is assembled, if it needs to be used for a long time, pins can be used to fix the insert cylinder 1 230 and the insert cylinder 220 on different stair treads 210 as needed).
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
