Abstract
The utility model belongs to the field of constructional engineering, and particularly relates to a jack-raising steel form with reserved holes, which is used for reserving holes in a concrete structure. The jack-raising steel form with the reserved holes comprises steel plates, steel ribs, nuts and rotary screws; four steel plates are welded to define a frustum-shaped structure; the upper opening of the frustum-shaped structure is greater than the lower opening of the frustum-shaped structure; two steel ribs are arranged, one steel rib is provided with two nuts and two ends of the two steel ribs are respectively welded on oppositely arranged steel plates; two rotary screws are arranged, top ends of the rotary screws are perpendicularly welded with handles, the tail ends of the rotary screws are provided with screw threads, and the rotary screws are matched with the nuts. The jack-raising steel form with the reserved holes is simple in structure, formed at a time, convenient to manufacture and construct, high in adaptability, material-saving and environment-friendly and can be recycled; the steel form is convenient to fix, accurate in positioning, convenient to erect and detach, the manpower is saved, the construction cost is reduced, the reserved holes are not deformed after the form is detached, and concrete quality is guaranteed.
Description
Technical field
The utility model belongs to building engineering field, particularly, relates to a kind of jacking type hole to be provided steel form, for concrete structure reserved opening.
Background technology
Nowadays the reserved opening in structure (as cigarette air channel, constructional column etc.) is substantially for wooden form is made, existing drawback is more, in embedded process,, after concrete is built, easily there is displacement, rising phenomenon in fixing inconvenience, and form removal difficulty, form removal very easily destroys reserved opening periphery concrete, and template deformation after form removal destroys and can not reuse, and has not only wasted manually but also wasted material.The project of executing at present is all adopted in this way, is necessary to develop a kind of novel reserved opening formwork for this reason.
Utility model content
The problems referred to above that exist for overcoming prior art, the utility model provides a kind of jacking type hole to be provided steel form.
For achieving the above object, the utility model adopts following proposal:
Jacking type hole to be provided steel form, comprising: steel plate, reinforcing bar, nut, rotary screw; Wherein: steel plate has four, four block plate welding enclose taper type structure, and the size suitable for reading of taper type structure is larger than end opening; Reinforcing bar has two, wherein on a reinforcing bar, two nuts is set, and the two ends of every reinforcing bar are welded on respectively on the steel plate being oppositely arranged; Rotary screw arranges two, the top vertical welding jug of rotary screw, and rotary screw end is with screw thread, and rotary screw matches with nut;
Preferably, steel plate adopts the thick steel plate of 3mm, and the size suitable for reading of taper type structure is than the large 2cm of end opening;
Preferably, two reinforcing bar right-angled intersections arrange, and reinforcing bar adopts 20 reinforcing bars; Article two, the infall spot welding of reinforcing bar is fixed;
Preferably, two nuts are symmetrical arranged about another reinforcing bar, nut and reinforcing bar welding;
Preferably, the two ends of every reinforcing bar are welded on respectively the steel plate center being oppositely arranged;
Preferably, screw thread length is higher than 1/2 of template height, and rotary screw height is higher than steel form height 15cm, and handle adopts 14 reinforcing bars, and handle length is 15cm.
With respect to prior art, the utlity model has following beneficial effect: jacking type hole to be provided steel template structure is simple, one-shot forming, makes and easy construction; Applicability is strong, can have enough to meet the need and recycle, material-saving environmental; Punching block convenient fixing, registration, punching block props up, tears open conveniently, saves artificial, saving cost, and after form removal, reserved opening is indeformable, and concrete quality is guaranteed.

Fig. 2 is the front elevational schematic of jacking type hole to be provided steel form.
Detailed description of the invention
As shown in Figure 1 and Figure 2, jacking type hole to be provided steel form, comprising: steel plate 1, reinforcing bar 2, nut 3, rotary screw 4; Wherein: steel plate 1 has four, and steel plate 1 adopts the steel plate that 3mm is thick, four block plate 1 welding enclose taper type structure, and the size suitable for reading of taper type structure is than the large 2cm of end opening; Reinforcing bar 2 has two, two reinforcing bar 2 right-angled intersection settings, and the two ends of every reinforcing bar 2 are welded on respectively steel plate 2 centers that are oppositely arranged; Reinforcing bar adopts 20 reinforcing bars 5; Article two, the infall spot welding of reinforcing bar 2 is fixed; 3, two nuts 3 of two nuts are wherein set on a reinforcing bar 2 and are symmetrical arranged about another reinforcing bar 2, nut 3 welds with reinforcing bar 2; Rotary screw 4 arranges two, and rotary screw 4 ends are with screw thread, and rotary screw 4 matches with nut 3; Screw thread length is higher than 1/2 of template height, and rotary screw 4 height are higher than steel form 1 height 15cm, the top vertical welding jug of rotary screw 4, and handle adopts 14 reinforcing bars, and handle length is 15cm.
After concrete construction completes, while utilizing the rotation of rotatable screw rod with the generation interaction force of platform template, thereby steel form is ejected, facilitate and do not destroy concrete.
