Abstract
The utility model is a kind of bellows locator, is made up of transverse steel and U-shaped reinforcing bar, and the termination of transverse steel and U-shaped reinforcing bar connects into an entirety, and transverse steel both ends are connected with concrete structure reinforcing bars, and bellows is positioned in U-shaped locator.This bellows locator structure is reasonable in design, shortens the construction period under the guaranteed precondition of construction technology, reduces construction cost, accurate positioning, ensures prestress wire construction quality, is positioned and constructed with bellows suitable for science of bridge building prestress wire.
Description
Technical field
The utility model belongs to science of bridge building pre-stress construction field, and in particular to a kind of prestress wire bellows
Locator.
Background technology
In science of bridge building, mobile load caused by the walking such as bridge superstructure dead load and automobile relies primarily on prestress steel twist
Line is undertaken, therefore the positioning of steel strand wires bellows is particularly important.Bellows locator relatively common at present is " well " font,
Use for tendon bellows mainly by four bar connectings with some strength, is fixed on " well " font by this locator
Interior, although such locator accurate positioning, in practical operation, working procedure is more complicated, and the engineering time is longer, is constructed into
This is higher, and pad is more, and welding procedure process caused welding slag with during can very likely damage bellows, need to be to ripple
Line pipe is repaired, and otherwise concrete composition, which is flowed into bellows, makes its blocking, is caused steel stranded wire penetrating adapter, tensioning difficult, is influenceed
Steel strand wires construction quality.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of bellows locator, this locator
It is not only simple in structure, accurate positioning, and construction period section, cost is low, can guarantee that the integrality of bellows, so as to further protect
Demonstrate,prove steel strand wires construction quality.
The technical solution of the utility model is：A kind of bellows locator, is made up of transverse steel and U-shaped reinforcing bar, laterally
The termination of reinforcing bar and U-shaped reinforcing bar connects into an entirety, and transverse steel both ends are connected with concrete structure reinforcing bars, bellows is determined
In U-shaped locator.
Described transverse steel can be straight line or curve.
The shape of described U-shaped reinforcing bar can be circular arc or arbitrary polygon.
When described U-shaped reinforcing bar is connected with transverse steel, both ends can be vertical with transverse steel, or meets desired times
Meaning angle, two ends also can use welding, can also use other on one side of transverse steel in its both sides, type of attachment
Connected mode.
Good effect of the present utility model：The bellows locator combined by the simple reinforcing bar of two root architectures is not only fixed
Level is true, and it is time-consuming few to construct, and cost is low, close to the solder joint only 1-2 of bellows position, and is all located at ripple bottom of the tube,
The destroyed probability of bellows can be substantially reduced, this simple and reliable for structure, few using material, construction cost is low；Construction procedure
Simply, take less, accurate positioning is easy to operate；Bellows nearby solder joint only 1-2, and be located at ripple bottom of the tube, welding process base
Originally bellows will not be damaged, steel stranded wire penetrating adapter, tensioning are unaffected, so as to ensure prestress wire construction quality.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, for ordinary skill people
For member, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model bellows locator structure schematic diagram（Sectional drawing）.
In figure：1- transverse steels, 2-U shape reinforcing bars, one end of 3- reinforcing bars 1, the other end of 4- reinforcing bars 1,5,6- pads, 7-
Bellows, 8,9- concrete structure reinforcing bars.
Embodiment
As shown in figure 1, the transverse steel 1 of bellows locator external force as caused by bearing prestressing force self gravitation and construct
Prevent its U-shaped reinforcing bar 2 for moving left and right and floating from forming with positioning prestressing force, transverse steel 1 connects into one with U-shaped reinforcing bar 2
It is overall.
Transverse steel 1 can be straight or curve, and can be vertical with bellows 7, can also appoint into meet to require
Meaning angle.The shape of U-shaped reinforcing bar 2 is not only limited to circular arc or arbitrary polygon, and U-shaped reinforcing bar 2 connects with transverse steel 1
When connecing, both ends can be vertical with transverse steel 1, or meets desired any angle, and two ends can be the one of transverse steel 1
Side, also welding can be used, can also use other connected modes, according to welding, 3 and 4 is equal in its both sides, bar connecting form
Should weld, can only welding 5 and 6 in a bit, also can 2 points weld.The selection of material generally meets the round steel of intensity requirement
Or screw-thread steel, it also may be selected to meet desired other materials, such conversion is all fallen within the scope of protection of the utility model.
During construction, after installation concrete structure reinforcing bars 8,9, bellows is placed in structure reinforcing bars, surveying setting-out is fixed
The elevation of position bellows, by the position of positioning, the both ends 3 and 4 of transverse steel 1 and concrete structure reinforcing bars 8,9 are welded, weldering
Bellows 7 is placed on transverse steel 1 after the completion of connecing, the particular location of repetition measurement bellows 7, U-shaped reinforcing bar 2 is used after errorless by ripple
Line pipe 7 is positioned in U-shaped reinforcing bar, the connection U-shaped of welding 5 or 6 reinforcing bar 2 and transverse steel 1, the choice of material of bellows locator,
The technique such as spacing arrangement and welding procedure should perform according to drawing or related specifications.
