Description
Technical field
The utility model belongs to bridge, constructing tunnel concreting and structure installation field, is related to Cast-in-situ Beam and applies
Stent used in work, and in particular to a kind of jacking of the cast-in-place boom support of truss-like.
Background technology
Cast-in-situ Beam superstructure is frequently with rack construction.In the mountain ridge and River Valley Region because of landform and Geological Reasons at bridge location,
Cast-in-place boom support cannot use full framing structure, and use structure across steel pipe support greatly, but be needed during steel pipe frame installation between component
Weld, when being removed after construction, difficulty is again larger.Traditional handicraft is usually direct cutting of steel tubing string, or in steel pipe support
After-poppet dismounting is terminated in order to construct as temporary support using sandbox when setting up.Cutting of steel tubing string, easily occurs safe thing
Therefore and waste of material it is serious.Sandbox is adjusted supporting structure absolute altitude due to being not easy when it is installed, and has certain limitation
Property.
The content of the invention
The purpose of this utility model is that for the problem of cast-in-place boom support installing and dismounting is difficult at present, there is provided a kind of cast-in-place
The jacking of boom support, is arranged on the top of bracket upright post, using fabricated construction, is mounted and dismounted easy to stent.
The technical solution of the utility model is as follows：
A kind of jacking for the cast-in-place boom support of truss-like, it is characterised in that：Including base, adjusting screw rod and upper pallet,
The base lower end is equipped with 3 downward projection of support connection-pegs, and each connection-peg is a cylindrical structure, close to cylinder lower end
Position be equipped with annular groove, base upper end is a positioning pipe, and the adjusting screw rod lower end is inserted into the positioning pipe of base, and
Fixed by adjusting nut, adjusting screw rod upper end is fixedly connected with upper pallet bottom surface, and the top surface of the upper pallet is equipped with least four
The positioning pin projected upwards.
The utility model is simple in structure, easy for installation, and structural elevation can be finely adjusted when stent is set up, and can meet structure
Installation accuracy needs.Stent dismounting, convenient and efficient, security can be achieved in the height that adjusting screw rod is reduced after pouring construction
It is high.Rewelding, dismounting damage steel pipe can be avoided, ensures that steel pipe is safe and reliable, increases its service life, and can be saved manually,
Economic benefit is obvious.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is a kind of occupation mode schematic diagram of the utility model；
Fig. 3 is the cross-sectional view of base, the cord tissue that display positioning inside pipe wall is set.
Embodiment
As shown in Figure 1, the utility model includes base 1, adjusting screw rod 2 and upper pallet 3,1 lower end of base is equipped with 3
Downward projection of support connection-peg 4, each connection-peg 4 is a cylindrical structure, and it is recessed to be equipped with annular close to the position of cylinder lower end
Groove 5, base upper end are a positioning pipes 6, and 2 lower end of adjusting screw rod is inserted into the positioning pipe 6 of base, and passes through adjusting nut
7 fix, and 2 upper end of adjusting screw rod is fixedly connected with 3 bottom surface of upper pallet, and the top surface of the upper pallet 3 is projected upwards equipped with least four
Positioning pin 8.
2 upper end of adjusting screw rod and the connection mode of 3 bottom surface of upper pallet can be connected by screw bolts.It is equipped with the bottom surface of upper pallet
Two pieces of connecting plates 9, the upper end of adjusting screw rod 2, which is equipped with along the perforative screw hole of adjusting screw rod diameter, 2 upper end of adjusting screw rod, is placed in pop-up
Between the connecting plate 9 of two pieces of plate bottom surface, and fixed by connecting bolt with two connecting plates.
As shown in Fig. 2, the utility model is suitable for the cast-in-place boom support of truss-like, in particular by triangular truss as vertical
The stent of column.When the utility model is used, installed in 10 top of column of triangular truss stent, 3 connection-pegs 4 of base 1
It is inserted into respectively in 3 steel pipes of bracket upright post, the fastening bolt 11 in steel pipe, fastening bolt is led in the installation of column outer wall of steel pipe
In the annular groove 5 of 11 front ends insertion connection-peg front end, the utility model and bracket upright post are fixed.The upper supporting beam 12 of stent
On jacking upper pallet 3, multiple pin holes are preset in upper supporting beam, and insert by the positioning pin 8 of pin hole and jacking plate top surface
Connect.To keep upper supporting beam to stablize, fixing bolt folder 13 also can use to fix between jacking plate 3 and upper supporting beam 12.
The utility model not only plays a supportive role on stent, can also play support height fine setting.Jacking is on column
After installation is fixed, its height that is spirally connected on screw rod 2 is adjusted by adjusting nut 7, controllable adjustable screw rod 2 is in base positioning pipe
Inserting depth in 6, so as to adjust the height of whole jacking, and then realizes and support height is finely adjusted.
Adjusting screw rod 2 rotates together during to prevent that adjusting nut 7 from rotating, and at least two can be equipped with adjusting screw rod outer wall
Along the locating slot 14 of adjusting screw rod axial direction.As shown in figure 3, it is equipped with 6 inner wall of positioning pipe of base with determining on adjusting screw rod 2
The raised line 15 that position groove coordinates.In the positioning pipe of adjusting screw rod lower end insertion jacking seat, the raised line 15 on 6 inner wall of positioning pipe is caught in tune
Save in the locating slot 14 on screw rod, make adjusting screw rod can not axial rotation.
