Abstract
The utility model discloses a kind of double steel cylinder temporary supports for precast beam installation, double steel cylinder temporary supports include steel plate, master cylinder, auxiliary cylinder, master cylinder diameter is more than auxiliary cylinder diameter, master cylinder bottom welding steel, the built-in fine sand of master cylinder, is placed on the bent cap for having poured completion, the auxiliary cylinder concrete filled, auxiliary cylinder is mounted in master cylinder after age to be achieved, forms double steel cylinder temporary supports；The utility model is easy to make, and installation is easy, reusable, overcomes precast beam construction temporary support and removes difficult situation, the construction quality of prefabricated beam bridge is improved, especially suitable for the precast beams bridge construction such as precast hollow slab, prefabricated case beam.
Description
Technical field
The utility model is related to double steel cylinders in a kind of temporary support more particularly to a kind of precast beam installation to prop up temporarily
Seat.
Background technology
In the construction of precast prestressed concrete upper beam, according to construction technology, precast beam is transported after Liang Chang completes
To on-site hoisting, the bearing that when lifting uses is secondary to install permanent bearing, temporary support again when pouring continuous segment for temporary support
Play the role of extremely important in precast beam lifting, it directly affects the construction quality of bed rearrangement bridge.Conventionally employed interim branch
Seat more generally precast concrete block, wood directly buy commercially available temporary support.Although precast concrete block has
There are enough rigidity and intensity, can guarantee the stabilization of precast beam, but dismounting is relatively difficult, expends the time, efficiency is low；Wood holds
It is readily removable to remove, but deformation may be shunk under the weight of precast beam, it can not ensure precast beam construction quality；Commercially available interim branch
Seat is expensive, increases construction input.
Therefore, it is badly in need of needing a kind of reasonable for structure, easy to demolition, the temporary support with certain rigidity.
Invention content
In order to keep precast beam easy for installation, fast, accelerate site operation progress, ensures cast-in-place rear bed rearrangement bridge precast beam construction
Quality, the utility model proposes a kind of simple in structure, low cost, rigidity is big, is adjusted, the readily removable temporary support removed.
To achieve the above object, the utility model proposes following technical solutions：Double steel cylinder temporary supports include steel plate,
Master cylinder, auxiliary cylinder, master cylinder diameter are more than auxiliary cylinder diameter, master cylinder bottom welding steel, and master cylinder built-in fine sand is filled out in the auxiliary cylinder
Concrete, auxiliary cylinder are mounted in master cylinder.
Preferably, steel plate length of side master cylinder diameter.
Preferably, fine sand is closely knit, fills and leads up, concrete fills up auxiliary cylinder.
The double steel cylinder temporary supports of the utility model have the advantages that compared with traditional temporary support：
1, simple in structure, it is easy to make, the concrete used structure can pour remaining concrete based on, and fine sand can
Live material-taking on-site, low manufacture cost are reusable.
2, the rigidity of structure is big, is unlikely to deform, and precast beam construction quality is guaranteed.
3, it overcomes temporary support and removes difficult situation, avoid destroying beam body in demolishing process, construction is safer
Reliably.
4, speed block is removed, construction efficiency is high, shortens the period, reduces management cost.
Description of the drawings

Fig. 2 is the double steel cylinder temporary support vertical views of the utility model.
Each component label in figure：1-steel plate；2-master cylinders；3-auxiliary cylinders；4-fine sands；5-concrete.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making the creative labor
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, double steel cylinder temporary supports include steel plate 1, master cylinder 2, auxiliary cylinder 3, and 2 diameter of master cylinder is more than auxiliary cylinder
3 diameters, 2 bottom welding steel 1 of the master cylinder, 2 built-in fine sand 4 of master cylinder are placed on the bent cap for having poured completion, fine sand 4 exists
Through closely knit processing in master cylinder 2, it is filled to about 3/4 position of 2 depth of master cylinder, concrete 5 is filled up in the auxiliary cylinder 3, smoothed out, wait for up and down
Auxiliary cylinder 3 is mounted in master cylinder 2 after reaching age.
Wherein, 2 diameter 219mm of master cylinder, wall thickness 4mm, auxiliary cylinder 3 diameter 159mm, wall thickness 4mm, the height of auxiliary cylinder 3 and master cylinder 2
It can be depending on on-site actual situations.
When making the utility model, two steel pipes of suitable diameter are first cut into the master cylinder 2 that length is 15cm-20cm
With auxiliary cylinder 3, the cutting of steel plate 1 is square, and the length of side is more than 2 diameter 2cm of master cylinder, and the welding of master cylinder 2 on the steel plate 1 is poured in auxiliary cylinder 3
Concrete 5 is built, is conserved after smoothing out up and down.
The temporary support of the utility model is when in use：According to construction technology, general every piece of precast beam need to place two per side
A temporary support, surveying and locating positions the position of temporary support, master cylinder 2 is placed on oriented bent cap, built-in to master cylinder 2
Fine sand controls temporary support elevation by adjusting fine sand depth, and precast beam is mounted on temporary support using crane or Bridge Erector
On, after the completion of lifting, permanent bearing is installed, the cast-in-place continuous segment of assembled formwork, after the completion of maintenance, with water by temporary support master cylinder 2
Interior fine sand 4 is gone out, and the total elevation of temporary support declines, and is drawn off taking out, moves to next working face and be continuing with.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
