Description
Technical field
The utility model relates to build demoulding equipment field more particularly to a kind of precast stair built-in fitting stripper.
Background technique
As country is for energy-saving and environment-friendly call, domestic more and more build uses precast construction, in precast construction
The reason of most commonly precast stair, precast stair is widely used is that the staircase structure of customization is relative complex, wood glue plate
Assembled formwork is time-consuming and laborious, while the quality of stair is difficult to ensure when pouring, fitted up after the completion of pouring it is complex, but it is prefabricated
Stair are assembled with large form in factory, while while pouring is vibrated using comprehensive, effectively increases production efficiency and product
Quality.
But for precast stair, after precast stair reaches lifting intensity, need to take out built-in fitting, but it is existing
Some built-in fitting removal methods, which generally use, manually taps built-in fitting with weight, takes out built-in fitting after built-in fitting loosening, this
Kind mode can generally cause certain damage, precast stair lesser for the thickness of customization, this weight to stairwell surface
Percussion mode certain breakage may be caused to the interface of built-in fitting so that precast stair is in lifting, to generate interface broken
Equal dangerous situations are split, therefore how in the case where not damaging precast stair, taking out built-in fitting becomes art technology
Personnel's urgent problem to be solved.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides one kind and does not damage
The precast stair built-in fitting stripper of precast stair.
The utility model is to be achieved by the following technical programs: a kind of precast stair built-in fitting stripper, including sky
The double threaded screw being socketed inside heart built-in fitting, hollow built-in fitting and the pressure apparatus for stretching double threaded screw, pressure apparatus
Consolidate including top board, with the side plate of top board one, by two hinged eccentric wheels of eccentric shaft and side plate and with eccentric wheel
Surely the handle connected, the middle part of top board are equipped with the screw hole for being socketed double threaded screw, and the lower end of double threaded screw is equipped with for locking
First bolt of tight hollow built-in fitting, the upper end of double threaded screw are equipped with the second bolt for locking top board, the first bolt and
Second bolt is matched with nut respectively.
According to the above technical scheme, it is preferable that the lower part of two eccentric wheels is equipped with the backing plate with ground face contact.
According to the above technical scheme, it is preferable that the upper end diameter of hollow built-in fitting is greater than lower end diameter.
According to the above technical scheme, it is preferable that gasket is equipped between the first bolt and the second bolts and nuts.
According to the above technical scheme, it is preferable that the quadrangle of top board and side plate is smooth arc-shaped.
The beneficial effects of the utility model are: the utility model drives double threaded screw to move upwards by eccentric wheel, and it is double
Head screw rod drives hollow built-in fitting to move upwards, thus realize in the case where not damaging built-in fitting and precast stair, it will be empty
Heart built-in fitting smoothly takes out；The utility model can adjust double end according to the rising situation of built-in fitting using double threaded screw in time
The nut of screw rod upper end, to more can more efficiently take out built-in fitting.
Detailed description of the invention
Fig. 1 shows the schematic view of the front view of embodiment according to the present utility model.
In figure: 1. hollow built-in fittings, 2. double threaded screws, 3. pressure apparatus, 4. top boards, 5. side plates, 6. eccentric shafts, 7. partially
Heart wheel, 8. handles, 9. screw holes, 10. first bolts, 11. second bolts, 12. nuts, 13. backing plates.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model provides a kind of precast stair built-in fitting stripper, including hollow built-in fitting 1, sky
The double threaded screw 2 being socketed inside heart built-in fitting 1 and the pressure apparatus 3 for stretching double threaded screw 2, pressure apparatus 3 include upper
Pressing plate 4 is consolidated with the side plate 5 of 4 one of top board, by two hinged eccentric wheels 7 of eccentric shaft 6 and side plate 5 and with eccentric wheel 7
Surely the handle 8 connected, the middle part of top board 4 are equipped with the screw hole 9 for being socketed double threaded screw 2, and the lower end of double threaded screw 2, which is equipped with, to be used
In the first bolt 10 for locking hollow built-in fitting 1, the upper end of double threaded screw 2 is equipped with the second bolt 11 for locking top board 4,
First bolt 10 and the second bolt 11 are matched with nut 12 respectively.
According to above-described embodiment, it is preferable that the lower part of two eccentric wheels 7 is equipped with the backing plate 13 with ground face contact.
According to above-described embodiment, it is preferable that the upper end diameter of hollow built-in fitting 1 is greater than lower end diameter.
According to above-described embodiment, it is preferable that be equipped with gasket 14 between the first bolt 10 and the second bolt 11 and nut 12.
According to above-described embodiment, it is preferable that the quadrangle of top board 4 and side plate 5 is smooth arc-shaped.
The beneficial effects of the utility model are: the utility model drives double threaded screw to move upwards by eccentric wheel, and it is double
Head screw rod drives hollow built-in fitting to move upwards, thus realize in the case where not damaging built-in fitting and precast stair, it will be empty
Heart built-in fitting smoothly takes out；The utility model can adjust double end according to the rising situation of built-in fitting using double threaded screw in time
The nut of screw rod upper end, to more can more efficiently take out built-in fitting；The lower part of the utility model eccentric wheel be equipped with
