Specific embodiment
The utility model is further elaborated in referring to Fig.1~Fig. 3, and a kind of template being easy to lift precast hollow slab is auxiliary
Device is helped, including cored slab formwork for placing bottom is arranged in and along the auxiliary device main body of the elongated setting of cored slab width direction,
Auxiliary device main body includes symmetrically arranged support base 1, and horizontally disposed adjustable plate 7 is respectively fixed at the top of support base 1, is adjusted
Plate 7 is located at 1 two sides of support base and is symmetrically arranged with jacking screw rod 2, is respectively arranged on the jacking screw rod 2 of 7 upper and lower ends of adjustable plate
First adjusting nut 6 and the second adjusting nut 5 are symmetrically arranged at the top of the jacking screw rod 2 of two ipsilateral settings of support base 1
The support frame plates 3 vertical with adjustable plate 7, support frame plates 3 and jacking screw rod 2 connect, and are fixed with top plate at the top of support frame plates 3
4。
1 lower part of support base is fixed on mattess, and support base 1 is the composite structure of square terrace with edge and cuboid, and square
Top surface size is identical as cuboid bottom surface size on terrace with edge.Support frame plates 3 are oppositely arranged for the opening of angle steel and angle steel.Jacking
Rotational handle 9 is fixed on screw rod 2, rotational handle 9 is vertically set on 2 middle part of jacking screw rod.First adjusting nut 6 and second is adjusted
The internal diameter of section nut 5 is identical and is arranged concentrically, and is fixedly connected with adjustable plate 7.Two adjusting nuts, which are arranged, can aid in top
It rises screw rod 2 to keep stablizing, prevents jacking screw rod 2 from shaking in process of rising or falling.
The specific steps of hollow board prefabrication construction are carried out using the utility model are as follows:
Hollow board prefabrication template lower part concrete pedestal 8 is handled, wherein each precast hollow slab formwork for placing is matched
Cover two auxiliary device main bodys, two auxiliary device main bodys be symmetricly set on along formwork for placing it is long to and away from respective end 20~
The position of 30cm.That is: two elongated grooves are set in the lower part concrete pedestal 8 for placing cored slab formwork for placing,
Auxiliary device main body is placed into groove and ensures that the size of top plate 4 is identical as the sectional dimension of groove.
Further, the stroke of jacking screw rod 2 is adjusted by rotational handle 9, so that jacking screw rod 2 moves upwards drive
The support frame plates 3 and 4 composite structure of top plate for being in contact with it connection move vertically upwards, until the top end surface and coagulation of top plate 4
The either flush of earthen platform seat 8, concrete pedestal 8 are used as the bed die of precast hollow slab formwork for placing.
After the side form and filled internal mold of cored slab formwork for placing are set in concrete pedestal 8, precast hollow slab can be carried out
Pour.It is vibrated in time in concreting process and carries out necessary maintenance construction after the completion of pouring, to prefabricated
After cored slab reaches defined design strength, it can be hung and concentrated and be put.
Before lifting, operation rotational handle 9 is moved downward screw rod 2 is jacked, so that contacting 3 He of support frame plates of connection
The composite structure of top plate 4 moves downward therewith, generates sky therewith by the cored slab bottom of the top plate 4 and prefabricated completion that move down
Gap；It operates the auxiliary device main body of another location and forms the gap identical as cored slab bottom of top plate 4.
Further, it is lifted after rope out of gap respectively.
After rigging out, so that top plate 4 is returned to original position by operating rotational handle 9, the prefabricated of next mould cored slab can be carried out
Construction.
The utility model passes through the auxiliary device main body that can be stretched up and down, realizes that top plate 4 serves as prefabricated sky when pouring
The part backplane of core serves as the dual purpose of hoisting port in lifting.Wherein, the combination of support base 1 and jacking lead screw 2 can be with
It is replaced using hydraulic jack.Due in the utility model, jack the adjusting of lead screw 2 by cored slab pressure act on compared with
It is small, and for the considerations of reducing processing cost purpose, the utility model uses jacking screw rod 2 as main lifting part.
