[0027] In another technical solution, the fastening plate includes a fastening plate 1 4 and a fastening plate 2 3, which are respectively arranged on the steel column at intervals from top to bottom, the fastening plate 2 is horizontally connected to the working platform, and the fastening plate 1 is detachably connected to the outer end of the working platform through multiple supports 7. Two fastening plates are arranged above and below to achieve stable support for the working platform, such as Figure 7 and Figure 8 It is a structural form of a fastening plate one and a fastening plate two.

[0028] In another technical solution, a connection block protruding upward is arranged around the outer end of the fastening plate 1, and the support is connected to the connection block of the fastening plate 1. The arrangement of the connection block facilitates connection.

[0029] In another technical solution, the modular platform plate includes four modular platform plates one, eight modular platform plates three, and a plurality of selectively arranged modular platform plates two, the modular platform plates one and the modular platform plates two are both congruent squares, the template platform plate three is an isosceles triangle and the waist is equal to the side length of the square corresponding to the modular platform plate two, the four modular platform plates one are centrally symmetrically located on the four sides of the steel column, the eight modular platform plates three are equally divided into four parts and centrally symmetrically located at the four diagonals of the steel column, and the template platform plate two is selectively located on both sides of the modular platform plate one according to the size of the steel column.

[0030] like Figures 4 to 6 They are modular platform plate 1, modular platform plate 2 and modular platform plate 3. The three different forms of modular platform plates are reasonably assembled according to the cross-sectional size of the steel column. Figure 3 As shown, for steel columns with smaller cross-sectional dimensions, Figure 3 The three types of steel column structures in the middle and upper parts form the working platform through four modular platform plates 1 and eight modular platform plates 3; for steel columns with larger cross-sectional dimensions, Figure 3 The two types of steel column structures in the middle and lower parts form a working platform through four modular platform plates 1, eight modular platform plates 2 and eight modular platform plates 3.

[0034] In another technical solution, Fig. 9 and Fig.10 As shown, the fastening plate includes four equal pieces, and a fastening pad 10 is fixedly arranged on the fastening plate close to the inner wall surface of the steel column.

Since manual operation usually stands on one side of the work platform to perform construction, and then moves to the other side, such as standing on the left side, the left side is continuously stressed, and there is a force tilted toward the left side. Under normal conditions, the thicker end of the shape unit on the fastening pad is compressed, and the thinner end of the shape unit just contacts the steel column, such as Fig.10 As shown, the thicker upper end of the corresponding shape unit on the left is relaxed, and the thinner lower end of the shape unit is compressed, so that the whole is fastened to the steel column; and the fastening force corresponding to the right side is exactly opposite to that of the left side, so that the overall fastening force is stable and balanced.

[0036] In another technical solution, the fastening plate includes four equal pieces, and the modular assembled work platform assembly method includes the following steps: First, four modular platform plates 1 and the corresponding fastening plates 1 are connected as a whole through a crossbeam, and at the same time, the stiffening connecting plates on the crossbeam are connected to the corresponding fastening plates 2 through supports, so as to form four first components as a whole; Secondly, any two modular platform boards three or any two modular platform boards three and corresponding two modular platform boards two are connected as a whole according to the design requirements to form four second components; Again, the four first components are respectively installed on the steel column and fixed, and then the four second components are installed accordingly; or any two adjacent first components are connected as one, and then installed on the steel column and fixed, and finally the four second components are installed accordingly; Finally, install vertical guardrail posts and steel wire ropes on the assembled work platform to complete the assembly.

[0037] like Fig.11 As shown, the two red parts and the two black parts together constitute the four fastening plates 1 corresponding to the four first components, the four fastening plates 2 directly below the two red parts and the two black parts, and the four modular platform plates 1 corresponding to the two red parts and the two black parts horizontally and vertically, including the corresponding beams, stiffening connecting plates, and supports, are pre-assembled as one to form four first components, which is convenient for overall installation on the steel column, improves construction efficiency, reduces construction risks, and simplifies operation difficulty. At the same time, according to the size of the steel column, two modular platform plates 3 or any two modular platform plates 3 and two modular platform plates 2 perpendicular to and located on both sides thereof are also assembled into four second components, such as Fig.11 In this way, the entire assembly platform is pre-assembled into multiple large components according to the design requirements, and then installed on the steel columns, which greatly improves the assembly efficiency and reduces the assembly risk.

[0038] The prior art is to connect different components by welding. The present invention considers connecting standard parts by bolts through standard fastening parts. Bolt fastening can be easily disassembled and reused. At the same time, the connection method is adapted to the cross-section changes of different steel columns, and a modular design is adopted. The parts of the present invention are made of galvanized material, which has good anti-corrosion performance.

[0039] The modular assembled work platform of the present invention includes 4 standard parts and 3 non-standard parts. The standard parts are modular platform plates (divided into three types), guardrail columns, supports (angle steels), and wire meshes; non-standard parts include fastening plate 1, fastening plate 2, and wire ropes. There are three types of modular platform plates. There are bolt holes on the sides of the modular platform plates. The modular platform plates are connected with bolts.

There are universal bolt holes on the crossbeam below the modular platform plate 1 and it is bolted to the fastening plate 2. The modular platform plate 1 is bolted to the fastening plate 1 through the support. The sizes of the fastening plate 1, fastening plate 2, and wire rope are related to the size of the steel column. All connections are bolted, which is convenient for installation and disassembly.

[0040] like Figures 4 to 6As shown, there are three types of modular platform boards: square modular platform board 1, modular platform board 2 and triangular modular platform board 3. Figure 3 As shown in the figure, the combination of three different types of modular platform plates can adapt to the installation of box columns, round tube columns, H-shaped steel columns and cross columns with different cross sections. The difference between modular platform plate 1 and modular platform plate 2 is that a crossbeam is added in the middle of modular platform plate 1, and a stiffening connecting plate is set under the crossbeam. Parametric bolt holes are set on the stiffening connecting plate, which are connected to the fastening plate 1 and the support respectively.
