Abstract
The invention discloses a kind of mould bases at circle hole, the lower end of screw rod is rotatably supported in the hole of base, nut is transferred on the screw rod, otic placode is evenly equipped with the outer peripheral face of nut, the upper end of connecting plate is hinged with the otic placode on the nut, the lower end of the connecting plate is hinged with the otic placode on sole, and the upper end of the screw rod is provided with handwheel.The remarkable advantage that the present invention has assembling, removal efficiency is high, quality is good and applied widely.
Description
Technical field：
The present invention relates to a kind of instrument for building, is particularly used for forming the mould bases of circular opening mould plate.
Background technology：
The circular hole for having diameter different is set up on building, makees a circular mould bases man-hour requirement is applied, then
Concrete is poured outside circular shuttering on this mould bases, forms circular hole.Existing mould bases adopts two circles of template construct, then will with batten
Two circles connect into a cylinder and are placed at construction hole, are poured, and remove after construction, and this mould bases make efficiency is low, no
Can reuse, circular hole error is big, and quality is low.
Content of the invention：
The present invention seeks to a kind of mould at circle hole that a kind of make efficiency of design is high, quality is good and applied widely
Frame.
The technical scheme is that, a kind of mould bases at circle hole, it is characterised in that：The lower end of screw rod is rotatably supported in
In the hole of base, nut is transferred on the screw rod, is evenly equipped with otic placode on the outer peripheral face of nut, the upper end of connecting plate with described
Otic placode on nut is hinged, and the lower end of the connecting plate is hinged with the otic placode on sole, and the upper end of the screw rod is provided with handwheel.?
On the medial surface of each sole and it is respectively provided with two upper and lower otic placodes on nut to cut with scissors with the two ends of two identical connecting plates respectively
Connect, upper and lower two otic placodes on upper and lower two otic placodes and nut on each sole all not in same vertical plane, institute
The cross section for stating sole is arc.
The remarkable advantage that the present invention has assembling compared with the prior art, removal efficiency is high, quality is good and applied widely.
Description of the drawings：
Fig. 1 is the structural representation of the present invention.
Specific embodiment：
The lower end that the present invention has following embodiments, screw rod 2 is rotatably supported in the hole of base 1, and nut 3 is transferred on the spiral shell
On bar, uniform otic placode 8 on the outer peripheral face of nut, the upper end of connecting plate 5 are hinged with the otic placode, on the inside of its lower end and sole 6
Otic placode 7 on face is hinged, and the upper end of the screw rod is provided with handwheel 4, is easy to rotate screw rod, can be obtained by equal by rotating handwheel
The circular hole of the different-diameter that the sole of cloth is surrounded, is trapped among on the outer peripheral face of each sole with steel band, after spot welding fixation at connecting sewing,
Placing concrete can be carried out, make the building body in circular hole hole.During dismounting, rotation nut makes its rising, and each sole shrinks and steel
Band departs from, while steel band is taken out.For the high precision of circular hole that makes, the quantity of uniform connecting plate and sole should be more；
After the round diameter that sole is surrounded is fixed, each sole should be made in vertical state, the circular holes misconduct for otherwise surrounding, can people
Work is realized, or connecting plate is changed to threaded body with the bearing pin in sole upper ear plate hole, during adjustment, unclamps nut, and adjustment determines
Tightening nuts make the vertical state of sole not change afterwards, and this method efficiency is low；It is respectively provided with each sole and nut upper and lower
Two otic placodes, are connected with the upper and lower otic placode on sole and nut by two identical connecting plates, the efficiency of this scheme respectively
Height, but when the angle very little that connecting plate shrinks, i.e., the round hour that sole is surrounded, two on each sole otic placode should not be
In same vertical plane, now, sole needs certain width, and now the cross section of sole should be arc, it is ensured that steel
The radius that band encloses circle is more accurate, and the otic placode on nut is matched with the otic placode position on sole.
Claims (2)
1. a kind of circle hole mould bases, it is characterised in that：The lower end of screw rod is rotatably supported in the hole of base, and nut is transferred on
On the screw rod, otic placode is evenly equipped with the outer peripheral face of nut, the upper end of connecting plate is hinged with the otic placode on the nut, described
The lower end of connecting plate is hinged with the otic placode on sole, and the upper end of the screw rod is provided with handwheel.
2. described in claim 1 a kind of circle hole mould bases, it is characterised in that：On the medial surface of each sole and on nut
It is respectively provided with upper and lower two ears that two upper and lower otic placodes are hinged with the two ends of two identical connecting plates respectively, on each sole
All not in same vertical plane, the cross section of the sole is arc to upper and lower two otic placodes on plate and nut.
