[0004] However, when the above device is actually used, the safety component is only provided with protective plates on the front and rear sides, and there are no protective devices on the left and right sides. When workers stand on the construction frame, they are likely to fall and slide out from the left and right sides of the safety component, increasing the safety hazard of the workers. In addition, the height to which this construction frame can be raised and lowered is limited, making it difficult to build the construction frame on higher buildings. Therefore, a construction frame that improves the safety of workers and increases the construction height is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 、 Figure 2 and Figure 5 , a safe construction frame:

[0024] It includes: a connecting plate 1, both sides of the connecting plate 1 are fixedly connected to the first support rod 2, the other two sides of the connecting plate 1 are fixedly connected to the second support rod 3, the surface of the first support rod 2 is rotatably connected to the connecting ring 4, the surface of the connecting ring 4 is fixedly connected to the support plate 5, one side of the support plate 5 is fixedly connected to the fixing hook 6, one side of the connecting ring 4 is fixedly connected to the connecting rod 7, one side of the fixing hook 6 is fixedly connected to the fixing tube 8, the inner wall of the second support rod 3 is slidably connected to the limiting slider 9, one side of the limiting slider 9 is fixedly connected to the connecting block 10, one side of the connecting block 10 is fixedly connected to the limiting ring 11, the inner wall of the limiting ring 11 is rotatably connected to the fixing rod 12, and the surface of the fixing rod 12 is threadedly connected to the inner wall of the fixing tube 8, the surface of the support plate 5 is provided with a slot 22, and both sides of the slot 22 are semicircular, and the slot 22 is in the middle of the support plate 5.

[0025] When the worker climbs to different heights through the support plates 5, and needs to stand on the construction frame at a specified height, the worker rotates the fixing rod 12 to make the fixing rod 12 move upward and disengage from the fixing tube 8, and makes the fixing rod 12 drive the limiting ring 11 to slide upward, and the limiting ring 11 drives the connecting block 10 to slide upward, and the connecting block 10 drives the limiting slider 9 to slide upward, so that the fixing rod 12 is disengaged from the fixing tube 8, and the limiting ring 11 restricts the fixing rod 12 to prevent the fixing rod 12 from being lost. At this time, the fixing hook ring 6 is disengaged, and the support plate 5 is pulled outward, so that the support plate 5 drives the connecting ring 4 to rotate, so that the support plate 5 drives the fixing hook ring 6 to rotate and open, thereby making it convenient for the worker to step on the top of the construction frame.

[0026] See also Figure 3 and Figure 4 The middle parts of the first support rod 2 and the second support rod 3 are fixedly connected with a support frame 13, and the support frame 13 is cross-fixed. The top of the connecting plate 1 is overlapped with a strap 14, and the bottom of the strap 14 is fixedly connected with a limit rod 15 all around, and the surface of the limit rod 15 is inserted into the inner wall of the connecting plate 1. A square groove is provided on the top of the strap 14, and the top of the strap 14 is fixedly connected with a top pipe 16 all around. The inner wall of the top pipe 16 is threadedly connected with a top rod 17. The top of the top rod 17 is fixedly connected with a knob 18, and the knob 18 is provided with semicircular protrusions all around.

[0027] When fixing the strap 14 by this device, during installation, the strap 14 is placed on the top of the connecting plate 1, and the limit rod 15 is inserted into the circular hole on the top of the connecting plate 1, so that the strap 14 is difficult to move laterally, and then the connecting clamp 19 is rotated, so that the connecting clamp 19 drives the top rod 17 at the bottom to rotate and rise, so that the knob 18 rises and contacts the bottom of the support frame 13, thereby restricting the strap 14, making it difficult for the strap 14 to rise, and tools and other devices can be hung on the jacking pipe 16 by rotating the knob 18 back and forth, so as to save the space occupied by the strap 14, so that the staff can stand on the strap 14 to repair the building.

[0028] See also Figure 1 The upper and lower ends of the first support rod 2 and the second support rod 3 are fixedly connected with connecting rings 19, and the inner wall of the connecting ring 19 is threadedly connected with a fixing bolt 20. The top ends of the first support rod 2 and the second support rod 3 are fixedly connected with a connecting tube 21, and the radius of the connecting tube 21 is the same as the radius of the inner wall of the first support rod 2 and the second support rod 3.

[0029] When the construction frame is spliced ​​and installed using this device, the first support rod 2 and the second support rod 3 of the second group of construction frames are mounted on the first support rod 2 and the second support rod 3 of the first group of construction frames, so that the connecting pipe 21 of the first group of construction frames is inserted into the bottom of the first support rod 2 and the second support rod 3 of the second group of construction frames. At this time, the two groups of connecting clips 19 are fitted together, and the fixing bolts 20 are passed through the two groups of connecting clips 19 and rotated to connect and fix the two groups of construction frames, thereby completing the splicing and fixation of the construction frames.

[0030] Working principle: multiple groups of construction frames are spliced ​​together through the first support rod 2 and the second support rod 3, and the fixing bolts 20 are rotated through the connecting clamps 19 to complete the splicing and fixing of the multiple groups of construction frames. At this time, the support plates 5 of the multiple groups of construction frames form a ladder, and the board 14 is placed on the top of the connecting plate 1, and the limiting rod 15 is inserted into the circular hole of the connecting plate 1. The staff climbs to the specified height through the support plate 5, and then rotates the fixing rod 12 to make the fixing rod 12 disengage from the fixing tube 8, and the fixing rod 12 drives the limiting ring 11 to move when moving upward, and the limiting ring 11 brings The movable connecting block 10 and the limiting slider 9 move upward. Since the limiting slider 9 is difficult to separate from the second support rod 3, the limiting ring 11 limits the fixing rod 12. At this time, the fixing rod 12 is not easy to be lost. After the fixing rod 12 is separated from the fixing tube 8, the support plate 5 can be rotated open. The staff stands on the top of the board 14 and hangs the tool on the jacking pipe 16, and turns the knob 18 so that the knob 18 is against the bottom of the support frame 13, effectively fixing the board 14 and limiting the tool, reducing the probability of the tool being separated from the jacking pipe 16, and then the building maintenance work at the specified height can be carried out.
