The I-shaped channel steels 3 extend outward from the front side of the lower floor slab 2 to form an overhanging section 31. A plurality of I-shaped channel steels 3 are provided and are spaced apart from each other on the left and right sides.

[0037] Specifically, the I-shaped channel steel 3 is fixed to the lower floor 2 by a plurality of groups of front-to-back distributed clamping assemblies 33, the clamping assemblies 33 include U-shaped studs 331, the belly of the U-shaped studs 331 is embedded in the lower floor 2 with two wings facing upward, the I-shaped channel steel 3 is located between the two wings of the U-shaped studs 331, and the I-shaped channel steel 3 abuts against the two wings of the U-shaped studs 331 through wooden wedges 332 embedded in the grooves thereof, the two wings of the U-shaped studs 331 are sleeved with pressure plates 333, and the pressure plates 333 clamp the I-shaped channel steel 3 through nuts 334 screwed to the top ends of the wings of the U-shaped studs 331. During the construction of the lower floor 2, the U-shaped stud 331 is embedded in the lower floor 2. When installing the I-shaped channel steel 3, first insert the wooden wedge 332 into the groove of the I-shaped channel steel 3 corresponding to the U-shaped stud 331 area, then place the I-shaped channel steel 3 between the two wings of the U-shaped stud 331 and make the wooden wedge 332 abut against the wings of the U-shaped stud 331, and finally, sleeve the pressure plate 333 on the two wings of the U-shaped stud 331 at the same time, and make the pressure plate 333 close to the top surface of the I-shaped steel through the nut 334. The I-shaped channel steel 3 is fixed by the embedded U-shaped stud 331, and the structure is relatively stable and reliable; the wooden wedge 332 can prevent the I-shaped channel steel 3 from moving in the left and right directions, thereby improving the stability of the overall structure.

[0038] It should be noted that Figure 2 The clamping assemblies 33 shown in the figure are provided with four sets and are distributed in pairs, and the two clamping assemblies 33 in each pair share the same wedge block.

[0039] Among them, refer to Figure 1 The bottom plate 4 is arranged horizontally and fixedly connected to the overhanging section 31, the rear end of the bottom plate 4 extends above the lower floor slab 2, and the front end of the bottom plate 4 is located behind the front end of the I-shaped channel steel 3 so that the front end of the I-shaped channel steel 3 is exposed to form a connecting section 32.

[0040] Specifically, the bottom plate 4 may be fixed to the overhanging section 31 by welding, bolts or other common means.

[0041] Furthermore, a plurality of support blocks 41 are provided below the bottom plate 4 and are spaced apart in the left-right direction. The support blocks 41 are fixed on the side walls of the lower floor 2 and are staggered with the I-shaped channel steel 3. The support blocks 41 can support the portion of the bottom plate 4 that is not supported by the I-shaped channel steel 3, thereby improving the bearing capacity of the bottom plate 4.

[0042] Furthermore, the rear end of the bottom plate 4 is bent downward to form a plurality of support plates 42 spaced apart in the left-right direction, and the support plates 42 are connected to the lower floor 2 and correspond one to one with the support blocks 41. The support plates 42 can support the rear end of the bottom plate 4, and can further improve the bearing capacity of the bottom plate 4 in cooperation with the support blocks 41.

[0043] Specifically, the bottom plate 4 is provided with a strip skirting board 43 arranged in the left-right direction, and the board surface of the strip skirting board 43 is arranged vertically and is located behind the rear column 53. The rear of the strip skirting board 43 is the main activity area for construction personnel, which separates the activity area of ​​construction personnel from the area where the support frame 5 is located, which can improve the safety of construction personnel's work on the one hand, and on the other hand, it can also block the goods placed on the bottom plate 4 to prevent the goods from sliding onto the protective net 6.

[0044] Among them, refer to Figure 1 , Figure 3 and Figure 4 The support frame 5 is composed of a first cross bar 51 arranged front and back, a second cross bar 52 arranged left and right, and columns 53. The columns 53 are provided in two rows distributed front and back, and all the columns 53 in the same row correspond to the I-shaped channel steels 3 one by one. The bottom ends of the front row columns 53 are fixed to the connecting sections 32 of the corresponding I-shaped channel steels 3, and the bottom ends of the rear row columns 53 are fixed to the bottom plate 4. The top layer first cross bar 51 is fixedly connected to the upper floor slab 1.

[0045] Specifically, a vertically arranged positioning steel bar 54 is fixed on the connecting section 32, and the positioning steel bar 54 is arranged adjacent to the bottom end of the corresponding front-row column 53 and locked by a clamp 55. During installation, firstly, the position of the positioning steel bar 54 is determined by marking on the bottom plate 4, and then the positioning steel bar 54 is fixed on the bottom plate 4. Finally, when installing the front-row column 53, it is only necessary to place the front-row column 53 adjacent to one side of the corresponding positioning steel bar 54, and then lock it by the clamp 55. It should be noted that the column 53 is generally a tubular structure, and the general fixing method of the existing column 53 is: firstly, the positioning steel bar 54 is installed, and then the bottom end of the column 53 is directly sleeved on the positioning steel bar 54, which has two technical defects: first, the diameter of the positioning steel bar 54 is smaller than the inner diameter of the column 53, and the column 53 still has a movable margin after assembly, and the structural stability is poor; second, when the assembly is completed and inspected, the inspector generally judges the position accuracy of the column 53 by the positioning steel bar 54, but because the positioning steel bar 54 is blocked by the column 53, it is easy to cause inspection errors.

[0046] Specifically, the bottom ends of the rear pillars 53 can be fixed to the bottom plate 4 by welding, bolts or other common means.

[0047] Among them, refer to Figure 1 , the protection net 6 is fixed on the front side of all the first cross bars 51 .

[0048] It is easy to understand that the main function of the protective net 6 is to prevent falling objects from high altitude.

[0049] Among them, refer to Figure 1 and Figure 5 The upper end of the inclined cable 7 is fixedly connected to the front side wall of the upper floor 1 and the lower end is connected to the connecting section 32.

[0050] Specifically, the inclined cable 7 includes a first steel wire rope 71, the upper end of which is connected to the side wall of the upper floor 1, the lower end of which is connected to a turnbuckle 72, the end of which away from the first steel wire rope 71 is connected to a second steel wire rope 73, the end of which away from the turnbuckle 72 is provided with a rope ring 74, and the rope ring 74 is sleeved on the connecting section 32. The tightness of the inclined cable 7 can be sleeved by the turnbuckle 72; sleeve the inclined cable 7 on the connecting section 32 by the rope ring 74 to improve the reliability of the connection.

[0051] More specifically, the second steel wire rope 73 is a single rope folded in half to form a rope loop 74 at the folded portion, and the rest of the rope except the rope loop 74 is clamped and fixed by buckles.

[0052] Among them, refer to Figure 1 and Figure 6 The protection assembly 8 includes a slide rail 81 fixed to the side wall of the upper floor 1 and arranged on the left and right sides, a slider 82 is connected to the slide rail 81, and the slider 82 is connected to a safety belt 84 through a rope 83. During operation, the construction worker directly ties the safety belt 84 to the body. When the construction worker moves, the safety belt 84 can move synchronously with the construction worker through the sliding of the slider 82, thereby avoiding frequent removal of the safety belt 84, making it more convenient to use and improving the operation efficiency.

[0053] Furthermore, a U-shaped limit frame 85 is fixed below the slider 82, and two wings of the U-shaped limit frame 85 are connected to the bottom surface of the slider 82. The belly of the U-shaped limit frame 85 is arranged on the left and right sides and a slip ring 86 is sleeved in the gap, and the slip ring 86 is connected to the rope 83. The rope 83 is connected to the slip ring 86, and the slip ring 86 is sleeved on the belly of the U-shaped limit frame 85. The belly of the U-shaped limit frame 85 provides a certain range of motion for the slip ring 86, so that when the construction personnel move slightly, the safety belt 84 can meet the needs through the movement of the slip ring 86. The slider 82 will only move when the construction personnel move to the next working position and make a large movement, so that the life of the slider 82 can be reduced due to frequent movement.

[0054] The working principle of the construction engineering climbing safety protection frame of this embodiment is as follows:

[0055] When in use, the protective frame is installed around the high-rise building, and the construction workers stand on the bottom plate 4 and wear the safety belt 84 provided with the protective frame to work. The bottom plate 4 is a solid structure pre-installed on the protective frame, and is adapted to the I-shaped channel steel 3, which can prevent the construction workers from getting injured due to stepping on empty space, and has a high safety factor; in addition, the protective frame has a safety belt 84, and the safety belt 84 can move synchronously with the construction workers when the construction workers move, and there is no need to remove the safety belt 84, which is more convenient to use and also improves the work efficiency.

[0056] The above is only a specific implementation of the utility model, so that those skilled in the art can understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
