However, the above construction method is only suitable for the installation of the inner roof panel. When installing the outer roof panel, most of the construction workers stand and walk directly on the steel structure beams. Although a safety rope is provided during the construction process, the range in which they can stand and walk is small, and the construction is inconvenient. In addition, there is still a risk of falling (falling in mid-air and being hung by a safety rope) when moving during the construction process.

[0033] Example: Reference Figure 1-4 A steel structure roof construction safety work platform shown includes a platform base plate 1 and a low fence 3 fixed above the platform base plate 1, and a side entrance is provided on one side of the low fence 3;

[0034] Two holding frames 2 symmetrically distributed along the middle of the platform substrate 1 are slidably mounted on the lower end of the platform substrate 1 through a connecting piece. A driving component 7 for driving the two holding frames 2 to move closer to or away from each other is also mounted on the lower end of the platform substrate 1;

[0035] The frame 2 is a U-shaped long block with an opening downward in cross section. The lower end of the frame 2 holds the steel structure roof strips tightly. The top wall of the frame 2 is rotatably connected to two sets of rollers 6.

[0036] A vertically lifting stop block 4 is slidably connected to the middle of the holding frame 2, and an anti-slip groove is arranged at the lower end of the stop block 4. When the stop block 4 is at the highest position, the lower end is higher than the lower end of the roller 6, and when the stop block 4 is at the lowest position, the lower end is lower than the lower end of the roller 6;

[0037] The holding frame 2 is also provided with an electric push rod 8 for driving the brake block 4 to rise and fall.

[0038] Based on the above structure, when carrying out the construction work of the steel structure roof, it is only necessary to install the working platform on the steel structure roof, so that the two holding frames 2 respectively hold two adjacent steel bars, so that the two groups of rollers 6 are in rolling contact with the upper ends of the steel bars, and the construction personnel only need to enter the low fence 3 to obtain a stable foothold, which is conducive to the construction personnel to carry out the construction work of the steel structure roof; during the construction process, it is only necessary to control the electric push rod 8 to start, so as to use the electric push rod 8 to push the brake block 4 down, so that the lower end of the brake block 4 is tightly pressed against the top of the steel bar, and at this time, the two groups of rollers 6 are separated from the steel bar, so as to fix the working platform, avoid the phenomenon of platform movement during the operation process, thereby ensuring the safety of the construction personnel when carrying out construction on the working platform;

[0039] In addition, by adjusting the distance between the two holding frames 2, the steel structure roof construction safety work platform can be installed on the steel structure factory roof with different rib spacing, thereby expanding the application scope of the steel structure roof construction safety work platform and making it more practical.

[0040] Furthermore, horizontally arranged side wheels 5 are installed on the inner walls of both sides of the holding frame 2. The side wheels 5 are fixed to the inner walls of the holding frame 2 through side columns 51. There are multiple side wheels 5 and they are evenly distributed along the side walls of the holding frame 2.

[0041] The use of the side wheels 5 can form a rolling connection while holding the side of the rail, which is more conducive to the stable sliding of the holding frame 2 on the rail, thereby facilitating the flexible movement of the steel structure roof construction safety work platform on the rail, and making it more convenient to use.

[0042] Furthermore, the roller 6 is located at the upper end of the side wheel 5, and the two sets of rollers 6 are rotatably connected to the inner top wall of the holding frame 2 through the mounting block 61;

[0043] The side wheels 5 and the rollers 6 are both provided with oblique anti-skid patterns.

[0044] By providing oblique anti-slip grooves on the side wheels 5 and the rollers 6, axial sliding between the side wheels 5 and the rollers 6 and the sandalwood strips during use can be avoided, thereby ensuring the stability of the side wheels 5 and the rollers 6 during use, so that the two can play a stable rolling connection role.

[0045] Furthermore, a main slide groove 21 is provided on the top wall of the holding frame 2, and the upper end of the brake block 4 slides in the main slide groove 21. Auxiliary slide grooves 22 are provided on both sides of the main slide groove 21, and sliding ears 41 slidably connected to the auxiliary slide grooves 22 are fixed on both sides of the upper end of the brake block 4;

[0047] Furthermore, the bottom surface of the platform substrate 1 is provided with two slide grooves 11 which are symmetrically distributed along the middle of the platform substrate 1 and extend laterally, and support plates 12 are fixed at both ends of the slide grooves 11;

[0048] The driving assembly 7 includes a servo motor 71, a bidirectional screw 72 and a connecting block 74, and the servo motor 71 is fixed to one side of one of the support plates 12;

[0049] The threaded portion on the bidirectional screw 72 is symmetrically arranged about the middle of the bidirectional screw 72 , and two bidirectional screws 72 are provided and rotatably connected between the left and right support plates 12 , and one end of one of the bidirectional screws 72 is drivingly connected to the output shaft of the servo motor 71 ;

[0053] When it is necessary to adjust the distance between the two holding frames 2, it is only necessary to start the servo motor 71. The servo motor 71 drives one of the two-way screws 72 to rotate, and at the same time drives the other two-way screw 72 to rotate through the transmission wheel and the transmission belt group 73, so that the two two-way screws 72 rotate synchronously in the same direction, so that the connecting blocks 74 on both sides are close to or away from each other, that is, the slider 75 is driven to slide along the slide groove 11, and the two holding frames 2 are also driven to move closer to or away from each other, so as to adjust the distance between the two holding frames 2, meet the needs of installing the steel structure roof construction safety work platform on the beams with different spacings, and enhance the applicability of the steel structure roof construction safety work platform.

[0054] Furthermore, the four corners of the upper end of the low fence 3 extend upward to form corner columns 31, and the adjacent corner columns 31 are fixed with buckles 32 on their sides that are close to each other.

The need for installing the steel structure roof construction safety work platform on the sandalwood strip is met, so that the two groups of rollers 6 are in rolling contact with the upper end of the sandalwood strip, and the side wheels 5 hug the side of the sandalwood strip to form a rolling connection. The construction workers only need to enter the low fence 3 to obtain a stable foothold, which is conducive to the construction workers to carry out the construction work of the steel structure roof; during the construction process, it is only necessary to control the electric push rod 8 to start, so that the electric push rod 8 is used to push the brake block 4 down, so that the lower end of the brake block 4 is tightly against the top of the sandalwood strip. At this time, the two groups of rollers 6 are separated from the sandalwood strip, so as to fix the work platform and avoid the platform moving during the operation process, thereby ensuring the safety of the construction workers when they are working on the work platform;
