Thus, during work, Screw arbor with nut at both-ends tensioning plugging device is installed in the mounting hole in template, can be around mounting hole
Rotation, template can be adjacent to assembling with template, and pattern hole is eccentric with mounting hole, by rotating big second bias on the device
Ring, so that mounting hole and the aperture on eccentric hoop are concentric, the cast-in-place face of the device is concordant with template face, can solve background skill
Three problems of the formwork referred in art.
According to embodiment of the present utility model, further optimization can also be made to the utility model, below for optimization after
The technical scheme of formation：
In order to facilitate installing and fixing the first eccentric hoop, first eccentric hoop has positioning step, first eccentric hoop
A part be arranged in model sheetinstallat hole, the positioning step of first eccentric hoop is arranged on the lateral wall of template.
In order to facilitate installing and fixing the second eccentric hoop, second eccentric hoop has positioning step, second eccentric hoop
A part be arranged in the hole of the first eccentric hoop, the positioning step of second eccentric hoop sets the outer face of the first eccentric hoop
On.
First eccentric hoop and/or the second eccentric hoop are inclined provided with convenient rotation first eccentric hoop and/or second
The adjustment structure of thimble.Thus, by rotating the first eccentric hoop and/or the second eccentric hoop, it is possible to achieve mounting hole and eccentric hoop
On aperture it is concentric.It is highly preferred that the adjustment structure is to be arranged in first eccentric hoop and/or the second eccentric hoop outer rim
Well.
In order to prevent slurries from being swelled from the gap of the second eccentric hoop and Screw arbor with nut at both-ends, second eccentric hoop and Screw arbor with nut at both-ends
Between be provided with sealing ring.
Based on same inventive concept, the utility model additionally provides a kind of formwork structure, and it includes two pieces of templates, two pieces
Prefabricated component or cast-in-place space are formed between template；Pass through described Screw arbor with nut at both-ends tensioning plugging device phase between two pieces of templates
Even；Two pieces of templates are fixed on one by the Screw arbor with nut at both-ends through the corresponding model sheetinstallat hole of two pieces of templates by locking nut
Rise.
During work, first installation form, as long as occurring without king-sized error, Screw arbor with nut at both-ends is by the mounting hole in template
It is interior, then the first eccentric hoop is installed, the first eccentric hoop is placed in the mounting hole in template, then the second eccentric hoop is installed, make
The eccentric orfice of two eccentric hoops passes through Screw arbor with nut at both-ends.The first eccentric hoop, the second eccentric hoop are rotated, the second eccentric hoop is placed in first inclined
In the eccentric orfice of thimble, locking nut is tightened after being installed in place, completes model sheetinstallat.Sealing ring is placed in the sealing of the second eccentric hoop
In groove, prevent concrete slurry from penetrating into the device.
Compared with prior art, the beneficial effects of the utility model are：Plugging device of the present utility model can ignore life
Small error in production and installation process, makes each template closely connect, solves pattern hole and the unmatched problem of mounting hole, and not
Need cast-in-place rear repairing backfill.
