Description

Technical Field

[0001] This utility model relates to the field of assembled steel platform technology, and in particular to an assembled steel platform. Background Technology

[0002] A modular steel platform is a platform structure that uses steel as the main building material and is assembled by combining pre-made standardized components in a specific connection method. It can be flexibly built according to actual use needs and can also be disassembled when not needed, making it convenient for transportation and reuse. It is suitable for various scenarios and functions such as load-bearing and operation.

[0003] Current steel structure platforms are not easy to assemble and lack stability.

[0004] An existing patent (publication number: CN211499677U) discloses a modular steel structure platform, including a splicing body, legs, a ladder frame, and a main support frame. Each leg includes a top plate, a bottom plate, a column, and fixing holes. A top plate is welded to the top of each column, and a bottom plate is fixed to the bottom of each column. Fixing holes are symmetrically formed on the surface of the top plate. A crisscrossing main support frame is provided on the top of each leg, and the staggered positions of the main support frames are fixedly connected to the fixing holes of the legs. The splicing body is arranged above the main support frame. Each splicing body includes a platform, a frame, and a grid frame. A frame is fixed to the bottom edge of the platform, and a grid frame is fixed to the inner side of the frame on the bottom surface of the platform. The splicing body is placed within the staggered area of ​​the main support frame. This modular steel structure platform has clear installation steps, is relatively simple to install, and has a relatively stable and even stress distribution, effectively improving both construction efficiency and stability and safety during use.

[0005] To address the aforementioned issues, existing patents offer solutions. However, in the use of existing modular steel platforms, the connection between components is prone to planar position deviations and angular tilts, making it difficult to guarantee the flatness of the platform surface structure. This can easily lead to localized stress concentrations. Furthermore, the installation process relies on manual alignment and adjustment, resulting in low assembly efficiency. Moreover, dimensional accuracy is greatly affected by human factors, making it easy for connections to loosen, causing overall structural deformation, reducing the service life and reliability of the steel platform, and increasing maintenance costs.

[0006] Therefore, a modular steel platform is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a modular steel platform that can solve the problems of existing modular steel platforms, such as planar position deviation and angular tilt between components, which make it difficult to ensure the flatness of the platform surface structure, local stress concentration, low assembly efficiency due to manual alignment and adjustment during installation, and large influence of human factors on dimensional accuracy, which can easily lead to loose connections, overall structural deformation, reduced service life and reliability of the steel platform, and increased maintenance costs.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a modular steel platform, comprising a column, a pre-assembly frame fixedly connected to the surface of the column, a crossbeam snapped into the inner wall of the pre-assembly frame, a fixing mechanism fixedly connected to the top of the crossbeam, brackets fixedly connected to the front and rear sides of the crossbeam, a support beam snapped into the inner wall of the brackets, a positioning rod movably connected to the inner wall of the pre-assembly frame, the surface of the positioning rod movably connected to the inner wall of the crossbeam, the fixing mechanism comprising a positioning plate, an installation plate fixedly connected to the right side of the positioning plate, a positioning block fixedly connected to the bottom of the installation plate, and the bottom of the installation plate contacting the top of the crossbeam.

[0009] Preferably, the inner wall of the mounting plate is provided with a pressing groove, and the surface of the positioning block is engaged with the inner wall of the crossbeam.

[0010] Preferably, the inner wall of the pre-assembly frame is fitted with a locking block, and the rear side of the locking block is fixedly connected to the front side of the positioning rod.

[0011] Preferably, a gasket is movably connected to the surface of the positioning rod, and the front side of the gasket contacts the rear side of the pre-assembly frame.

[0012] Preferably, the surface of the positioning rod is threaded with a nut, and the front side of the nut is in close contact with the rear side of the washer.

[0013] Preferably, the inner wall of the pre-assembly frame is provided with a slot for cooperating with the card block, and the inner wall of the pre-assembly frame is provided with a pre-assembly groove for cooperating with the crossbeam.

[0014] Preferably, the inner wall of the crossbeam is provided with a positioning groove for use with the positioning block, and the inner wall of the crossbeam is provided with a mounting hole for use with the positioning rod.

[0015] Preferably, the inner wall of the support beam is movably connected with bolts, and the surface of the bolts is threadedly connected to the inner wall of the bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application sets up a fixing mechanism, which is fixedly connected to the mounting plate by positioning blocks during use. During the installation stage, the positioning blocks can be embedded in the preset position of the inner wall of the crossbeam to form a precise limit on the mounting plate, avoiding in-plane positional offset and tilting during the installation process. The positioning plate and the mounting plate work together through fixed connection. By using an orderly stacked installation logic, the connection stability between the mounting plate and the crossbeam is enhanced, effectively suppressing the warping deformation of the mounting plate caused by load during subsequent use, and ensuring the flatness and mechanical performance continuity of the steel platform surface structure.

[0018] 2. This application sets up a pre-assembled frame and crossbeams. The pre-assembled frame and columns, as well as the brackets and crossbeams, are all pre-fixed connections. The support beams can be quickly assembled by engaging with the brackets, simplifying the installation process and reducing the probability of installation dimensional deviations caused by manual operation. The positioning rods inserted into the pre-assembled frame and crossbeams provide coordinated positioning, further strengthening the connection rigidity between the crossbeams and columns. All components are reinforced by modular connections and positioning rods, forming a continuous force transmission path. This improves the overall assembly efficiency while enhancing the overall load-bearing strength and stability of the steel platform structure. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 The present invention provides the following technical solution:

[0029] A modular steel platform includes a column 1, a pre-assembly frame 3 fixedly connected to the surface of the column 1, a crossbeam 4 snapped into the inner wall of the pre-assembly frame 3, a fixing mechanism 2 fixedly connected to the top of the crossbeam 4, brackets 5 fixedly connected to the front and rear sides of the crossbeam 4, a support beam 6 snapped into the inner wall of the brackets 5, a positioning rod 7 movably connected to the inner wall of the pre-assembly frame 3, the surface of the positioning rod 7 movably connected to the inner wall of the crossbeam 4, and the fixing mechanism 2 including a positioning plate 201, an installation plate 202 fixedly connected to the right side of the positioning plate 201, a positioning block 203 fixedly connected to the bottom of the installation plate 202, and the bottom of the installation plate 202 contacting the top of the crossbeam 4.

[0030] In this embodiment: By setting a fixing mechanism 2, during use, the positioning block 203 is fixedly connected to the mounting plate 202. During the installation stage, the positioning block 203 can be embedded in a preset position on the inner wall of the crossbeam 4 to form a precise limit on the mounting plate 202, avoiding in-plane positional offset and tilting during installation. The positioning plate 201 and the mounting plate 202 work together through a fixed connection. Utilizing an orderly stacked installation logic, the connection stability between the mounting plate 202 and the crossbeam 4 is enhanced, effectively suppressing the warping deformation of the mounting plate 202 caused by load during subsequent use, and ensuring the flatness of the steel platform surface structure. To ensure the continuity of integrity and mechanical performance, pre-assembly frames 3 and crossbeams 4 are set up. The pre-assembly frames 3 and columns 1, and the clamps 5 and crossbeams 4 are all pre-fixed. The support beams 6 can be quickly assembled by engaging with the clamps 5, simplifying the installation process and reducing the probability of installation dimensional deviations caused by manual operation. The positioning rods 7 are inserted into the pre-assembly frames 3 and crossbeams 4 for coordinated positioning, further strengthening the connection rigidity between the crossbeams 4 and columns 1. All components are reinforced by modular connections and positioning rods 7, forming a continuous force transmission path, improving the overall assembly efficiency while enhancing the overall load-bearing strength and stability of the steel platform structure.

[0031] Specifically, such as Figure 3 As shown, the inner wall of the mounting plate 202 is provided with a pressing groove 8, and the surface of the positioning block 203 is engaged with the inner wall of the crossbeam 4.

[0032] Specifically, such as Figure 5As shown, a locking block 9 is snapped into the inner wall of the pre-assembly frame 3, and the rear side of the locking block 9 is fixedly connected to the front side of the positioning rod 7.

[0033] Specifically, such as Figure 5 As shown, a gasket 10 is movably connected to the surface of the positioning rod 7, and the front side of the gasket 10 contacts the rear side of the pre-assembly frame 3.

[0034] In this embodiment: the pressing groove 8 provided on the inner wall of the mounting plate 202 can enhance the tightness of the contact between the mounting plate 202 and the crossbeam 4, and improve the stress stability of the mounting plate 202. By setting the locking block 9, the position of the locking block 9 and the positioning rod 7 can be fixed during use, which facilitates the subsequent work of limiting the crossbeam 4 by driving the positioning rod 7 through the locking block 9, preventing the crossbeam 4 from shaking during use. The gasket 10 on the surface of the positioning rod 7 contacts the rear side of the pre-assembly frame 3, which can disperse the pressure generated by the fastening force on the positioning rod 7, avoid damage to the pre-assembly frame 3 due to excessive force, and ensure the durability of the connection structure.

[0035] Specifically, such as Figure 5 As shown, the surface of the positioning rod 7 is threaded with a nut 11, and the front side of the nut 11 is in close contact with the rear side of the washer 10.

[0036] Specifically, such as Figure 5 As shown, the inner wall of the pre-assembly frame 3 is provided with a slot 12 for use with the slot 9, and the inner wall of the pre-assembly frame 3 is provided with a pre-assembly groove 13 for use with the crossbeam 4.

[0037] In this embodiment: by setting a nut 11, the nut 11 can be rotated on the surface of the positioning rod 7 during use, which makes it easy to restrict the position of the crossbeam 4 by the nut 11, and enhance the stability when the crossbeam 4 is connected to the pre-assembly frame 3. The slot 12 on the inner wall of the pre-assembly frame 3 cooperates with the slot 9, and the pre-assembly slot 13 cooperates with the crossbeam 4, which can provide precise installation space for the slot 9 and the crossbeam 4, ensure the accuracy of the component assembly position, improve the overall assembly accuracy, and reduce installation deviation.

[0038] Specifically, such as Figure 5 As shown, the inner wall of the crossbeam 4 is provided with a positioning groove 14 that cooperates with the positioning block 203, and the inner wall of the crossbeam 4 is provided with a mounting hole 15 that cooperates with the positioning rod 7.

[0039] Specifically, such as Figure 7 As shown, the inner wall of the support beam 6 is movably connected with bolts 16, and the surface of bolts 16 is threadedly connected to the inner wall of the bracket 5.

[0040] In this embodiment: the positioning groove 14 opened on the inner wall of the crossbeam 4 facilitates the positioning block 203 to be snapped onto the inner wall of the crossbeam 4 through the positioning groove 14. The mounting hole 15 opened on the inner wall of the crossbeam 4 facilitates the positioning rod 7 to be installed on the inner wall of the crossbeam 4 through the mounting hole 15. By setting the bolt 16, the support beam 6 and the bracket 5 can be rotated on the inner wall of the bracket 5 during use, which can restrict the position of the support beam 6 and improve the overall load-bearing capacity of the platform.

[0041] Working Principle: During the use of column 1, a fixing mechanism 2 is set up. During use, it is fixedly connected to mounting plate 202 via positioning block 203. During installation, positioning block 203 can be embedded in a preset position on the inner wall of beam 4, precisely limiting the mounting plate 202 and preventing in-plane positional offset and tilting during installation. Positioning plate 201 and mounting plate 202 work together through a fixed connection, utilizing an orderly stacked installation logic to enhance the connection stability between mounting plate 202 and beam 4, effectively suppressing warping deformation of mounting plate 202 due to load during subsequent use, and protecting the surface of the steel platform. The flatness and mechanical performance continuity of the structure are ensured by setting up pre-assembly frame 3 and crossbeam 4. Pre-assembly frame 3 and column 1, and clamp 5 and crossbeam 4 are all pre-fixed. Support beam 6 can be quickly assembled by clamping with clamp 5, simplifying the installation process and reducing the probability of installation size deviation caused by manual operation. Positioning rod 7 enters the pre-assembly frame 3 and crossbeam 4 for coordinated positioning, further strengthening the connection rigidity between crossbeam 4 and column 1. All components are reinforced by modular connection and positioning rod 7 to form a continuous force transmission path, improving the overall assembly efficiency while enhancing the overall load-bearing strength and stability of the steel platform structure.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
