Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and in particular relates to a steel frame staircase with a modular assembly structure. Background Art

[0002] Steel staircases used in construction are temporary vertical transportation facilities used for personnel movement and material transport during construction. Current steel staircases have numerous drawbacks. First, installation is complex and time-consuming, and most existing systems require on-site cutting and welding. Because they are not modular, extensive on-site cutting, welding, and adjustment of components is required, increasing installation time. This is because they are not prefabricated and standardized in the factory. A solution is to deploy specialized construction teams, but this increases labor costs and is subject to site constraints. For example, limited space can hinder efficiency and make progress difficult to maintain. Second, structural stability is significantly affected by on-site construction. Because they are not modular, improper on-site welding and other processes can easily lead to uneven stress distribution, creating potential safety hazards. The conventional approach is to strengthen quality inspections, but these inspection methods are limited, making them incapable of fully detecting hidden internal defects and increasing inspection costs. Third, cost control is difficult due to the complexity, time-consuming installation, and the potential for multiple adjustments, which in turn increases material and labor costs. A solution is to plan carefully, but the many variables in actual construction make full implementation difficult, resulting in a waste of resources. Therefore, a new structure is needed to address these technical issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a steel frame staircase with a modular assembly structure to solve the problems raised in the above background technology.

[0004] The utility model is realized through the following technical scheme: a steel frame staircase with a modular assembly structure, comprising: a staircase component one and a staircase component two, the staircase component one being connected to the staircase component two through a fixing component, the staircase component one comprising: a bearing platform one and a ladder board one, two mounting frames one being symmetrically mounted on the front surface of the bearing platform one, a ladder board one being mounted between the two mounting frames one, a supporting leg one being mounted on the lower surface of the bearing platform one, the staircase component two comprising: a bearing platform two and a ladder board two, the mounting structure of the staircase component two being matched with the mounting structure of the staircase component one, the fixing component comprising: a fixing plate and a fixing bolt, a fixing plate and a fixing bolt being mounted at the connection between the staircase component one and the staircase component two, and the height of the staircase component one being less than the height of the staircase component two.

[0005] As a preferred embodiment, a guardrail 1 is integrally installed on the upper surface of the supporting platform 1 and the upper surface of the mounting frame 1, and a mounting frame 1 is symmetrically installed on the left edge and the right edge of the front surface of the supporting platform 1 with the front lower and the rear higher at an angle of 35 degrees, and multiple ladder plates 1 are evenly welded between the two mounting frames 1.

[0006] As a preferred embodiment, the ladder plate 1 is arranged in a horizontal state, and two supporting legs 1 are symmetrically installed on the right edge of the lower surface of the supporting platform 1. The supporting platform 1 is structurally matched with the supporting platform 2. The front edge and the rear edge of the right side surface of the supporting platform 2 are symmetrically installed with a mounting frame 2 at a 45-degree angle, with the front lower and the rear higher.

[0007] As a preferred embodiment, a plurality of ladder plates 2 are evenly installed between the mounting frame 2, the ladder plates 2 are matched with the ladder plate 1 structure, and a plurality of support legs 2 are evenly installed on the lower surface of the mounting frame 2 and the lower surface of the supporting platform 2, respectively, and the lower ends of the support legs 1 and 2 are flush with each other.

When in use, since modular stair component 1 and stair component 2 are adopted and connected by fixing components, during the installation process, the construction workers can first prepare the stair component 1 and stair component 2 in appropriate positions respectively. Because they are modular, their size and weight are relatively easier to handle. They are not as bulky as traditional integral stairs and do not require complicated on-site welding processes, which greatly improves the installation speed.

[0009] As a preferred embodiment, a plurality of fixing bolts are evenly installed on the surface of the side of the two mounting frames away from the supporting platform 2, and the fixing bolts are connected to the left surface of the supporting platform 1. When in use, since the mounting structure of the stair assembly 2 matches the stair assembly 1, it is like a staircase. Figure 1 In this way, the two components can be precisely docked. This precisely matched structure, coupled with the function of the fixing plate and fixing bolts, makes the installation process smoother and more efficient. Construction workers can quickly install each component in place according to the designed installation steps, reducing the time for on-site adjustment and calibration.

[0010] After adopting the above technical solution, the beneficial effect of the utility model is as follows: by setting up stair component one, stair component one is connected to stair component two through a fixing component, and stair component one includes: a load-bearing platform one and a ladder plate one. When in use, since modular stair component one and stair component two are adopted and connected through a fixing component, during the installation process, the construction personnel can first prepare stair component one and stair component two in appropriate positions respectively. Because they are modular, their size and weight are relatively easier to handle, and no complicated on-site welding process is required, which greatly improves the installation speed. For some occasions where stairs need to be built quickly, such as temporary buildings or exhibition venues, the advantages of this convenient installation method are particularly obvious.

[0011] By setting up the staircase component 2, the staircase component 2 includes: a bearing platform 2 and a ladder plate 2, the installation structure of the staircase component 2 matches the installation structure of the staircase component 1, and the fixing component includes: a fixing plate and a fixing bolt. When in use, since the installation structure of the staircase component 2 matches the staircase component 1, it is like a ladder. Figure 1 In this way, the two components can be precisely docked. This precisely matched structure, coupled with the function of the fixing plate and fixing bolts, makes the installation process smoother and more efficient. Construction workers can quickly install each component in place according to the designed installation steps, reducing the time for on-site adjustment and calibration.
