Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
According to the figure 1-2, the safety protection structure for installing or dismantling the outer frame comprises a lifting rope 2 for tying and hanging the safety belt, a lifting rope fixing mechanism is fixedly arranged at the upper end of the building outer wall 3, the lifting rope is fixed on the lifting rope fixing mechanism and naturally hangs to form a hanging section, a hook 21 is arranged on the hanging section, and the hook is used for tying and hanging the safety belt. The lifting rope hangs naturally, and is more convenient for constructors to operate.
The lifting rope fixing mechanisms are two sets, the main body of each set of lifting rope fixing mechanism is a fixed rod 1, through holes 31 which penetrate through the inner side and the outer side of the outer wall and correspond to the fixed rods 1 of the two sets of lifting rope fixing mechanisms are formed in the outer wall 3, and the two through holes 31 are located at the same height; the fixing rod 1 is inserted into the corresponding through hole 31, two ends of the fixing rod penetrate out of the through hole, two ends of the fixing rod 1 are provided with circular rings, an inner circular ring 12 is arranged on the inner side of the outer wall 3, and an outer circular ring 13 is arranged on the outer side of the outer wall 3; the lifting rope 2 is fixed on the lifting rope fixing mechanism through outer circular rings 13 on the two fixing rods, and two ends of the lifting rope 2 naturally hang to form two hanging sections; the two suspension sections are provided with hooks 21; the locking rod 4 is inserted into the inner ring 12 to prevent the fixing rod 1 from falling off under the pulling of the lifting rope. The lifting rope is fixed with the outer circular ring in a knotting mode, and the lifting rope fixing device is simple in structure, easy to operate and reliable in fixing.
The utility model discloses a run through the dead lever that sets up on the outer wall and connect the lifting rope, connect the locking lever in the outer wall inboard at the dead lever, messenger's dead lever that can be fine does not deviate from the wall body, and then make the lifting rope that the dead lever is connected have very good steadiness, and then connect the safety belt on the lifting rope, can be so that the constructor who connects the safety belt all has a good protection at the installation of outrigger or demolish the in-process, even scaffold frame self collapses, because the lifting rope is fixed on the wall body, so can not make the safety belt inefficacy yet.
The through hole 31 is an inclined hole, and the height of the through hole 31 on the inner side of the outer wall is greater than that on the outer side. The protective structure needs to be dismantled after construction is completed, and the through hole is plugged by using materials. Because the through hole 31 is designed to be an inclined hole with a low outer part and a high inner part, rainwater can be prevented from permeating into the wall along the through hole, and the plugging requirement is reduced.
The aperture of the through hole 31 is larger than the diameter of the fixing rod 1; the wedge 5 is arranged at the through hole close to the inner side of the outer wall, and the wedge 5 is arranged between the fixing rod and the wall of the through hole to tightly wedge the fixing rod in the through hole to prevent the fixing rod 1 from shaking. The utility model discloses the through-hole size will be greater than dead lever and ring size to the ring can directly pass from the through-hole, easy to assemble demolishs with the later stage, will appear the problem that the dead lever rocked in the through-hole like this, for this reason, sets up wedge 5 and carves tightly in the clearance between dead lever 1 and through-hole 31, avoids dead lever 1 to rock, can make locking lever 4 more firm with the laminating of dead lever 1 and wall body, and then makes lifting rope 2 more firm.
The size of the cross section of the through hole 31 is gradually reduced from the inner side to the outer side of the outer wall, so that the outer ring 13 positioned at one end of the outer side of the through hole 31 can be better restrained, the shaking amplitude of the fixing rod is further reduced, and the fixing rod is more stable.
The hanging section is provided with a plurality of groups of hooks 21, each group of hooks 21 is four, and the four hooks 21 in the same group are symmetrically arranged on the left hanging section and the right hanging section in a left-right manner; each group of hooks is arranged at a position corresponding to the outer wall 3 at the height of a certain floor; each set of four hooks is used to connect with an i-shaped harness 22.

After the scaffold is dismantled to a certain height, the tying point of the safety rope needs to be lowered, therefore, an I-shaped safety belt hanging point (namely a hook) is arranged at the upper position of the outer wall of each floor, and after one floor of the scaffold is dismantled, the tying point of the I-shaped safety belt is moved down by one floor.
The transverse size of the through hole 31 is larger than the vertical size, and the transverse size of the through hole 31 is larger than the outer diameter of the inner ring 12; thus, the cross section of the through hole 31 is flat, and the machining amount of the through hole 31 can be reduced under the condition that the inner circular ring passes through the through hole. The locking rod penetrates through the inner circular ring along the vertical direction, and the length of the locking rod is larger than the maximum size of the cross section of the through hole.
A cross bar 41 vertical to the locking rod is fixedly arranged at the upper end of the locking rod 4, the length of the cross bar 41 is greater than the length of the inner diameter of the inner ring 12, and the cross bar is arranged above the inner ring 12; the lower end of the locking rod 4 is provided with a threaded section, a nut 42 is connected onto the threaded section, the outer diameter of the nut 42 is larger than the inner diameter of the inner circular ring 12, and the locking rod 4 is prevented from falling off from the inner circular ring 12 through constraint of the nut and the cross rod from two directions. The structure is very convenient to mount and dismount, the locking rod 4 is ensured not to fall off from the inner circular ring 12, and the effect of firm fixation is achieved.
Finally, it is noted that the above-mentioned embodiments illustrate rather than limit the invention, and that, while the invention has been described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
