Abstract
The invention discloses a formwork of a round opening. The lower end of a screw rod is rotationally supported in a hole of a base, a nut is rotationally matched with the screw rod, lug plates are evenly distributed on the outer peripheral face of the nut, the upper end of a connecting plate is hinged to the lug plates on the nut, the lower end of the connecting plate is hinged to lug plates on a foot plate, and a hand wheel is arranged at the upper end of the screw rod. The formwork has the remarkable advantages of being high in assembly and disassembly efficiency, good in quality and wide in application range.
Description
Technical field:
The present invention relates to a kind of instrument for building, especially for the mould bases forming circular holes mouth template.
Background technology:
The standing circular hole having diameter different on building, makes a circular mould bases executing man-hour requirement, builds concrete, form circle hole outside the circular shuttering then on this mould bases.Existing mould bases adopts template construct two circles, then with batten, two circles is connected into a cylinder and be placed on construction hole place, and build, remove after construction, this mould bases make efficiency is low, can not reuse, and circle hole error is large, and quality is low.
Summary of the invention:
The present invention seeks to design that a kind of make efficiency is high, quality good and the mould bases at a kind of circular hole applied widely.
Technical scheme of the present invention is, a kind of mould bases of circular hole, it is characterized in that: the lower end of screw rod is rotatably supported in the hole of base, nut is transferred on described screw rod, the outer peripheral face of nut is evenly equipped with otic placode, otic placode on the upper end of junction plate and described nut is hinged, and the otic placode on the lower end of described junction plate and sole is hinged, and the upper end of described screw rod is provided with handwheel.The two ends of junction plate identical with two respectively with nut being arranged respectively two upper and lower otic placodes on the medial surface of each sole are hinged, upper and lower two otic placodes on each sole and upper and lower two otic placodes on nut are not all in same vertical plane, and the cross section of described sole is arc.
The present invention has assembling compared with the prior art, removal efficiency is high, quality good and remarkable advantage applied widely.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
The present invention has following embodiment, the lower end of screw rod 2 is rotatably supported in the hole of base 1, nut 3 is transferred on described screw rod, uniform otic placode 8 on the outer peripheral face of nut, upper end and the described otic placode of junction plate 5 are hinged, otic placode 7 on its lower end and sole 6 medial surface is hinged, the upper end of described screw rod is provided with handwheel 4, be convenient to rotating screw bolt, the round hole of the different-diameter surrounded by uniform sole can be obtained by rotating handwheel, be trapped among on the outer peripheral face of each sole with steel band, after the spot welding of connecting sewing place is fixing, placing of concrete can be carried out, make the building body of round hole.During dismounting, rotating nut makes it rise, and each sole shrinks and departs from steel band, is taken out by steel band simultaneously.In order to the precision in the round hole of making is high, uniform junction plate and the quantity of sole should be more; After the round diameter surrounded when sole is fixing, each sole should be made to be vertical state, otherwise the circular holes misconduct surrounded, can manually realize, or change the bearing pin in junction plate and sole upper ear plate hole into threaded body, during adjustment, loosen nut, adjustment determines that rear tightening nuts makes the vertical state of sole not change, and this way efficiency is low; Each sole and nut arrange upper and lower two otic placodes respectively, be connected with the upper and lower otic placode on sole and nut by two identical junction plates respectively, the efficiency of this scheme is high, but when the angle that junction plate shrinks is very little, the i.e. circle hour that surrounds of sole, two otic placodes on each sole should not in same vertical plane, now, sole needs certain width, now the cross section of sole should be arc, guarantee that steel band encloses the radius of circle more accurately, the otic placode on nut and the otic placode position on sole match.
Claims (2)
1. the mould bases at a circular hole, it is characterized in that: the lower end of screw rod is rotatably supported in the hole of base, nut is transferred on described screw rod, the outer peripheral face of nut is evenly equipped with otic placode, otic placode on the upper end of junction plate and described nut is hinged, otic placode on the lower end of described junction plate and sole is hinged, and the upper end of described screw rod is provided with handwheel.
2. the mould bases at a kind of circular hole according to claim 1, it is characterized in that: the two ends of junction plate identical with two respectively with nut being arranged respectively two upper and lower otic placodes on the medial surface of each sole are hinged, upper and lower two otic placodes on each sole and upper and lower two otic placodes on nut are not all in same vertical plane, and the cross section of described sole is arc.
