Detailed Description
A construction method for treating building cracks comprises the following steps:
the first step is as follows: respectively drilling a cut-off hole at two ends of the crack 3 of the wall 7, knocking a PVC-U plastic pipe into each cut-off hole, and plugging one end of the crack 3 of the wall 7 by using the plastic pipes;
the second step is that: preparing two cover plates 1, covering the cover plates 1 with a PE film to facilitate the subsequent taking off of the cover plates 1, then covering the two cover plates 1 on two sides of a crack 3, fixedly connecting two ends of the two cover plates 1 through a first screw 2 arranged in a cut-off pipe 6, and sealing two sides of the crack 3 by the two cover plates 1;
the third step: and (3) filling structural adhesive into the crack 3 through the adhesive injection hole on the cover plate 1, and removing the cover plate 1 after the structural adhesive is cured.
The cut-off holes at the two ends of the crack 3 intercept the crack 3, so that the crack 3 can be effectively prevented from extending.
As shown in fig. 4, the upper wall 7 and the lower wall 7 of the crack 3 are connected by a plurality of sets of tightening mechanisms, each tightening mechanism includes a cutting groove 4 formed on two sides of the wall 7, second screws 9 are respectively arranged in the walls 7 at the upper end and the lower end of each cutting groove 4, two ends of each second screw 9 are respectively connected by a tightening device 5, each tightening device 5 includes a steel wire rope 57 and a pull ring 51 fixedly connected to the second screw 9, one end of each pull ring 51 is fixedly connected to a screw tube 52, one end of each steel wire rope 57 is fixedly connected to one of the screw tubes 52, the other end of each steel wire rope 57 is fixedly connected to a screw sleeve 58, the screw sleeve 58 is connected to the other screw tube 52 by a double-headed screw 56, the steel wire rope 57 is tightened by rotating the double-headed screw 56, as shown in fig. 3, both the tightening devices 5 and the second screws 9 are in. The upper wall body 7 and the lower wall body 7 of the crack 3 are connected through a plurality of groups of tightening mechanisms, so that the displacement of the upper building wall body 7 and the lower building wall body 7 is limited, the upper building wall body 7 and the lower building wall body 7 are combined into a whole, the strength of the building wall bodies 7 is improved, the packaging wall bodies 7 are safe to use, and meanwhile, the crack 3 is further prevented from extending.
As shown in fig. 1, the two adjacent sets of tightening mechanisms are different in length. The screw anchors are dispersed, so that the building wall 7 is uniformly stressed, and the building wall 7 is prevented from cracking at the anchors.
