The locking nut 63 is screwed with the screw 61 and is located on the side of the square column 51 facing the ground and away from the ground to fix the position of the screw 61 on the square column 51. The screw sleeve 62 is in threaded connection with one side of the screw 61 far away from the ground, and the screw 61 at the upper and lower positions is connected into a whole through the screw sleeve 62.
Referring to fig. 1, a safety net 8 is provided at one side of the frame body 1, which is far from the outer wall 9, and the safety net 8 seals a space between the frame bodies 1 at upper and lower positions. Stand and to install fourth installed part 6 on support body 1 after, can open between the support body 1 that is located the upper and lower position and hang safety net 8 to promote the security of outer scaffold, reduce the unexpected hidden danger that drops of constructor.
Referring to fig. 1, a diagonal brace 7 is provided on the square pillar 51 located at the lowermost layer, one end of the diagonal brace 7 is welded to a lock nut 63 below the square pillar 51, and the other end abuts against the wall surface of the outer wall 9 below the square pillar 51. The diagonal brace 7 can form a triangular support structure with the wall surface and the square column 51, and can assist in supporting the outer scaffold and reducing the offset of the outer scaffold when being stressed.
The implementation principle of the overhanging type outer scaffold convenient for repairing the wall body is as follows: before construction, stress analysis is carried out, and whether the pre-point meets the construction parameters is determined according to a calculation result. And (3) strictly auditing a building construction drawing and a structure construction drawing before the concrete of the main structure of the building is poured, and carrying out electronic layout arrangement on the embedded points and reasonably optimizing. After the pre-embedding position is determined, the first installation part 3 is installed on a steel bar mesh of the building, and the steel bar mesh is poured to enable the first installation part 3 to be pre-embedded in an outer wall 9 of the building.
Subsequently, a sealant is applied to the outer periphery of the connecting rod 42 at a portion to be connected to the connecting sleeve 31, and the second mounting element 4 is screwed into the first mounting element 3 by a socket wrench after the sealant is solidified. Next, a square column 51 is installed at one end of the connecting rod 42 away from the outer wall 9, and when the square column 51 is close to the outer wall of the outer wall 9 as much as possible, the direction of the square column 51 is adjusted so that one side of the square column 51 faces the ground and is parallel to the ground.
Next, the frame body 1 is placed on the square column 51, and the frame body 1 is supported by the square column 51 and the frame body 1 is fixed to the square column 51 by bolts. The constructor can then stand on the just erected frame 1 with the safety line tied up to install the fourth installation element 6. Firstly, a locking bolt is screwed off, a screw 61 is vertically inserted into a hole reserved on the square column 51 which is positioned on the same layer as the frame body 1, then the locking bolt is screwed on the screw 61 on one side of the square column 51 facing the ground, and a locking nut 63 positioned at the upper position and the lower position of the square column 51 on the screw 61 is abutted towards the square column 51 after the position of the screw 61 is adjusted. And then, after all the screws 61 are installed, the threaded sleeves 62 on the screws 61 are in threaded connection with the nearest screws 61 above the threaded sleeves 62, so that the screws 61 positioned at the upper and lower positions are connected into a whole, and the whole external scaffold is further formed into a whole.
And finally, a safety net 8 can be hung on one side of the frame body 1 far away from the outer wall 9, and an inclined stay bar 7 is installed below the bottommost square column 51 to assist in improving the safety of the outer scaffold. When the external scaffold is dismantled, after the overhanging scaffold is dismantled, the part of the connecting rod 42 extending out of the external wall 9 is cut off along the wall surface of the external wall 9 of the building by adopting oxyacetylene, and after the cutting is finished, the two sides of the external wall 9 are repaired by adopting cement mortar.
Compared with the traditional construction technology of the cantilever scaffold, the embedded first installation part 3 of the embodiment has small influence on masonry construction, and the first installation part 3 is matched with the second installation part 4, so that the potential safety hazard that the wall connecting rod is detached by leakage hidden danger caused by hole reservation and worker construction during masonry is reduced, the influence on a building structure is small, and the difficulty and the workload of repairing the outer wall 9 are reduced conveniently.
