Detailed Description

As shown in fig. 1-3, the present invention provides a technical solution: a novel embedded expansion bolt wall connecting piece for fixing a cantilever type scaffold comprises a steel plate 4 and pad feet 10, wherein a vertical bubble column 6 is embedded in the front surface of the steel plate 4, the vertical bubble column 6 is fixedly connected with the steel plate 4, a steel pipe 9 is fixedly welded at the right side center position of the steel plate 4, second round holes 12 are formed in the steel plate 4 close to four corners, a screw 14 penetrates through each second round hole 12, the screw 14 is in sliding connection with the second round holes 12, a handle 5 is fixedly connected to the right end of the screw 14, a nut 13 is in threaded connection with the outer side wall of the screw 14, the right side of the nut 13 is in contact with the left side of the steel plate 4, the pad feet 10 are fixedly connected to the left end of the screw 14, a third round hole 16 is formed in the pad feet 10, a first round hole 11 is formed in one side of the inner part of the steel plate 4 close to the second round hole 12, and expansion screws 3 are inserted in the first round hole 11 and the third round hole 16, expansion screw 3's left side is equipped with wall 1, the pre-buried expansion nut 15 that has in wall 1's right side, expansion screw 3's left end runs through to expansion nut 15's inside wall, expansion screw 3 can dismantle with expansion nut 15 and be connected, expansion screw 3 installs in expansion nut 15, both connections are firm, in follow-up when needing to dismantle the use tool alright in order to dismantle the separation, follow-up repair work volume to wall 1 is little, pre-buried expansion nut 15, even wall spare attaches the engineering quality of wall department and obtains guaranteeing, construction worker will fill up foot 10 and laminate on wall 1, the staff can observe vertical bubble post 6, can judge whether the side of steel sheet 4 inclines, in case find the slope, the staff can adjust nut 13, be in the vertical face with the side of steel sheet 4.

In this embodiment, the rear of steel pipe 9 is equipped with scaffold 7, and scaffold 7 can be dismantled with steel pipe 9 through fastener 8 and be connected, and fastener 8 is the part that building trade used often, can link together steel pipe 9 and scaffold 7, and follow-up can be dismantled.

In this embodiment, the quantity of the foot 10 of filling up is totally four, four foot 10 of filling up distribute in the left side of steel sheet 4, the right side of foot 10 of filling up and wall 1 contacts, foot 10 of filling up is flat cuboid shape, when even wall spare uses, foot 10 of filling up and wall 1 contact, compare in the component of tradition and wall 1 contact, the area of modified foot 10 of filling up and wall 1 contact is little, it leaves the space to fill up between foot 10 and the steel sheet 4, run into protruding wall 1 in middle part still can normal use sometimes, and, the improved is even wall spare stability is good.

In this embodiment, the circle center of the first circular hole 11 coincides with the circle center of the third circular hole 16, and the circle centers of the first circular hole and the third circular hole coincide with each other, so that the expansion screw 3 can be conveniently inserted into the steel plate 4 and the foot pad 10 by a worker.

In this embodiment, the specification of steel pipe 9 is A48 x 3.6, and expansion nut 15 constitutes expansion bolts with expansion screw 3, and pre-buried expansion nut 15 can avoid the follow-up damage to wall 1 in wall 1 to pre-buried fixed mode, the later stage does not have the seepage hidden danger.

In conclusion, the work flow of the invention is as follows: when the construction, it is pre-buried in wall 1 with expansion nut 15, at the later stage, construction worker will fill up foot 10 laminating on wall 1, at this moment, judge whether the steel sheet 4 side of this moment is vertical through vertical bubble post 6, when the vertical nothing slope of steel sheet 4, construction worker directly runs through steel sheet 4 and fills up foot 10 with expansion screw 3, and install expansion screw 3 in expansion nut 15 alright, when the staff judges the slope of steel sheet 4, the staff rotates nut 13, because steel sheet 4 when the installation, need contact with nut 13, position through proper adjusting nut 13, can be with steel sheet 4 on the plane, even there is the unevenness phenomenon in wall 1, still can use even wall spare, application scope is wide, connect firmly.
