Stick 4 may pass through the preformed hole and fully cooperation, prevent rod iron 4 excessively loose in the preformed hole, influence the fixed effect of rod iron 4
Fruit.And the both ends of the rod iron 4 expose on the pier stud 1, specially the both ends of rod iron 4 exceed 1 appearance of the pier stud respectively
Face 30-50cm preferably exceeds 1 outer surface 50cm of the pier stud in the present embodiment, with for the setting of steel jacket box 5 it is reserved empty enough
Between, make steel jacket box 5 that can be hung on the both ends of rod iron 4.Limit hole or limited block (not shown) can be also set at the both ends of rod iron 4, with
Steel jacket box 5 is fastened on rod iron 4.The steel jacket box 5 that shape is cuboid, and the steel are arranged on the both ends of the rod iron 4
The lateral surface opposite with the two of the pier stud 1 of casing 5 contacts.The steel jacket box 5 be equipped be used to support falsework drop dress
6 (in the dotted line frames in figure) are set, wherein falsework includes longeron 3, i.e. longeron 3 is supported on lowering device 6.
The lowering device 6 includes two pieces of wedge blocks, 61, two pieces of billets 62, screw rod 63 and nut 64, two pieces of wedges
Lower wedge block 612 in shape block 61 is set on the steel jacket box 5, and the inclined-plane of two pieces of wedge blocks 61 is oppositely arranged, described
Screw rod 63 passes through two pieces of wedge blocks 61, and two pieces of billets 62, which are respectively sleeved on screw rod 63, is located at two pieces of wedge blocks 61
The both sides and side larger with the area of two pieces of wedge blocks 61 contacts, for padding nut 64, the nut 64 is sheathed on
It can be in contact or abut with the billet 62 on the both sides of the screw rod 63 and after the nut 64 goes in the same direction rotation.Its
In, screw rod 63 is high-strength bolt.Wherein, two pieces of wedge blocks 61 can form a kind of cuboid, and the screw rod 63 is along the class
The central axial of cuboid passes through.Two nuts 64 adjust 64 spacing of nut by being relatively rotated on bolt 63 so that two wedge shapes
Block 61 moves up and down relatively along contact surface, achievees the purpose that adjust 611 top surface absolute altitude of upper wedge block.
The lowering device 6 allows the height of bent cap holder to obtain flexible modulation, by nut 64 on screw rod 63
Rotation adjusts the absolute altitude of wedge block 61, when the nut 64 of both sides goes in the same direction rotation, then absolute altitude raising, when the nut 64 of both sides
Opposite and go rotation, then absolute altitude reduces, therefore passes through the final height for realizing bent cap holder of rotation of the nut 64 on screw rod 63
The adjusting of degree.
Further, the thickness of each wedge block 61 is 4-6cm, in the trapezoid cross section of each wedge block 61,
The a length of 20-30cm of right-angle side of trapezoid cross section, a length of 4-6cm in top, following a length of 18-22cm.It is each described in the present embodiment
The thickness of wedge block 61 is preferably 5cm, and in the trapezoid cross section of each wedge block 61, the right angle length of side of trapezoid cross section is preferably
25cm, the upper length of side are preferably 5cm, and the lower length of side is preferably 20cm.Meanwhile the length and width of the billet 62 is 4-6cm,
Thickness is 1-2cm.The diameter 16-24mm of the screw rod 63, the length 50-70cm of the screw rod, the length 4- of the nut 64
6cm.The length and width of billet 62 described in the present embodiment is 5cm, thickness 1.2cm.The diameter of the screw rod 63 is excellent
It is selected as 18mm, the length of the screw rod is preferably 66cm, and the length of the nut 64 is preferably 5.5cm.By to wedge block 61
Setting is optimized with the dimensional parameters of screw rod 63, nut 64, makes it of wedge block 61 and billet 62, screw rod 63 and nut 64
Between fitness more coordinate, so that lowering device 6 is played better supporting role to falsework, be more convenient for high to bent cap holder
The flexible modulation of degree.
A kind of construction of adjustable for height bent cap holder of the utility model embodiment and form removal method, include the following steps：
(1) first, when pier stud 1 is constructed, the axially vertical direction on edge and bent cap 2 at the top of the pier stud 1
The punching circular hole (i.e. preformed hole) of reserved 90-110mm diameters.
(2) after pier stud 1 completes, the rod iron 4 of 95-105mm diameters is penetrated into hole to be provided, 4 both ends of rod iron exceed pier stud 1 respectively
Outer surface 30-50cm.
(3) steel jacket box 5 that shape is cuboid, the support base as lowering device 6 are inserted at 4 both ends of rod iron.
(4) lowering device 6 is placed in 5 top surface of steel jacket box, using the support system as falsework.
(5) two pieces of wedge blocks, 61, two pieces of billets 62 are pulled together by lowering device 6 by screw rod 63, pass through nut 64
It limits wedge block 61 to relatively move, upper wedge block 611 top of the falsework load action in two pieces of wedge blocks 61 so that
Two wedge blocks 61 have the tendency that relatively moving along inclined-plane, and this trend is converted into the axle center pulling force of screw rod 63.
(6) the rotating to adjust the absolute altitude of wedge block 61 on screw rod 63 by nut 64, when the nut 64 of both sides is opposite
And go rotation, then absolute altitude increases, and rotation is gone when the nut 64 of both sides is opposite, then absolute altitude reduction.In falsework demolishing process,
Only need to be opposite by nut 64 and go rotation, reduction by 61 absolute altitude of wedge block can then reserve sufficient space, realize dropping for falsework
It removes.
Wherein step (1) to (5) is the construction method of adjustable for height bent cap holder, and step (6) is adjustable using height
Bent cap holder method that absolute altitude and form removal is adjusted.
Above description is the detailed description for the preferable possible embodiments of the utility model, but embodiment is not limited to
The patent claim of the utility model, the same changes or modifications completed under the technical spirit suggested by all the utility model
Change, should all belong to the covered the scope of the claims of the utility model.
