The counter-vault adjusting device is composed of adjustable height supporting rods arranged in rows and arrays on the side of a concrete pedestal on a support base plate, the adjustable height supporting rods adopt a screw rod in threaded connection with a fixing nut to fix a mounting board with a through hole on the side wall of the concrete pedestal, the fixing nut is fixed onto the mounting plate, the screw hole of the fixing nut is corresponding to the through hole of the mounting plate, the screw rod is first in threaded connection with a positioning nut, and then passes through the through hole to be in threaded connection with the fixing nut. The counter-vault adjusting device of the bridge beam prefabricating forming external mould base plate has the benefits of simple and convenient structure, convenience in application, and reworking prevention, and is mainly used for counter-vault adjustment of the bottom die of the bridge.
Description
Technical field
The utility model relates to bridge prefabrication field, especially a kind of bridge prefabrication moulding mold bottom plate antiarch adjusting device.
Background technology
Recent years, country greatly develops high-speed railway, and high-speed rail bridge mainly contains two kinds of beam types, and a kind of is the single box single chamber bridge, and a kind of is single case pair chambers bridge.
After bridge has just been built moulding, need the beam type is carried out prestressed stretch-draw several times, beam is known from experience generation compression under the prestressing force effect, and pontic can after using after a while, bridge floor will occur higher than the situation of design altitude slowly to arch, is called the arch of prestressing force bridge.
Bridge prefabrication moulding mold bottom plate is supported by a plurality of precast bridge pedestals that the interval arranges usually.
In order to solve prestressing force bridge arch problem, when on the precast bridge pedestal, mold bottom plate being installed, increase in advance the metal mat of different-thickness below base plate, base plate is adjusted to certain camber, this camber encircles identical, the opposite direction of size in advance with bridge.After several times to beam body prestressed stretch-draw, the antiarch of base plate just offsets with the bridge arch, regulates thereby reach antiarch.
The pre-formed mold bottom plate antiarch of present stage high-speed rail bridge regulation technology, the various different-thickness steel plates of main directly employing are raised bed die.Span own according to bridge, bed die is comprised of 3 meters wide templates of polylith, and quantity is many, and it is especially big that antiarch is regulated difficulty.When regulating the bed die antiarch, only allow the error of 1～2mm due to specification requirement, be difficult to reach demand of technical standard, usually occur doing over again, cause repeating welding, gas cutting, not only time-consuming, do not reach again instructions for use.
The utility model content
Regulate the deficiency of difficulty in order to overcome the pre-formed mold bottom plate antiarch of existing high-speed rail bridge, technical problem to be solved in the utility model is to provide a kind of simple and easy to do bridge prefabrication moulding mold bottom plate antiarch adjusting device.
The technical scheme that its technical problem that solves the utility model adopts is: bridge prefabrication moulding mold bottom plate antiarch adjusting device, described bearing plate is on the concrete pedestal, be arranged with the adjustment height support bar that vertically withstands base plate at described base plate, the setting in column in a row of each adjustment height support bar.
Described adjustment height support bar is arranged on the side of concrete pedestal.
Described adjustment height support bar adopts the screw rod that is threaded with hold-down nut.
Be fixed with the installing plate with through hole on the sidewall of concrete pedestal, described hold-down nut is fixed on installing plate, and its screw is corresponding with the through hole of described installing plate, and screw rod passes this through hole and is threaded with hold-down nut.
First be threaded on described screw rod and passed again this through hole after setscrew nut and be threaded with hold-down nut.
The beneficial effects of the utility model are: features simple structure, and it is convenient to use, and avoids doing over again, and the bed die inverted camber that is mainly used in bridge is regulated.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is K of the present utility model section enlarged drawing.
Be labeled as 1-base plate, 2-concrete pedestal, 3-adjustment height support bar, 4-installing plate, the pre-buried steel part of 5-, 20-sidewall, 31-hold-down nut, 32-screw rod, 33-setscrew nut, 40-hole in figure.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, bridge prefabrication moulding mold bottom plate antiarch adjusting device of the present utility model, described base plate 1 is bearing on concrete pedestal 2, is arranged with the adjustment height support bar 3 that vertically withstands base plate 1 at described base plate 1, the setting in column in a row of each adjustment height support bar 3.By adjusting each adjustment height support bar 3, make its bed die inverted camber up to standard, be encased inside again the steel plate of suitable thickness as backing plate on each concrete pedestal 2, and the backing plate point is welded on pre-buried steel spare 5, adjustment height support bar 3 falls in pine again, thereby base plate 1 just can remain on inverted camber position up to standard, and needn't repeatedly try pad and adjust, and has saved time and expense.
Be further, described adjustment height support bar 3 is arranged on the side of concrete pedestal 2, just can estimate the metal mat thickness of needs higher than the height of concrete pedestal 2 by comparison adjustment height support bar 3, has saved the time of examination pad.
Adjustment height support bar 3 can adopt the jack of pad on a pad etc., and easy to adjust for making its features simple structure, described adjustment height support bar 3 adopts the screw rod 32 that is threaded with hold-down nut 31.
Particularly, can be fixed with the installing plate 4 with through hole 40 on the sidewall 20 of concrete pedestal 2, described hold-down nut 31 is fixed on installing plate 4, and its screw is corresponding with the hole 10 of described installing plate 4, and screw rod 32 passes this through hole 40 and is threaded with hold-down nut 31.
Be further, pass again this through hole 40 after the setscrew nut 33 that first has been threaded on described screw rod 32 and be threaded with hold-down nut 31, loosening thereby assurance screw rod 31 can hold out against base plate 1 when adjusting puts in place.
Embodiment:
Certain beam making bench adopts bridge prefabrication moulding mold bottom plate antiarch adjusting device of the present utility model.
Beam making bench comprises a plurality of concrete pedestals 2 of layout in column in a row, be used for support baseboard 1, all be embedded with pre-buried steel part 5 in the bight of each concrete pedestal 2, be welded with horizontally disposed installing plate 4 on pre-buried steel part 5, through hole 40 is arranged on installing plate 4, be welded with hold-down nut 31 on installing plate 4, the screw of hold-down nut 31 is corresponding with described through hole 40, passes this through hole 40 after the setscrew nut 33 that first is threaded on screw rod 32 again and is threaded with hold-down nut 31 and forms adjustment height support bar 3.
Its course of work is: at first adjust each screw rod 32 with respect to the extension elongation of hold-down nut 31, make its bed die inverted camber up to standard, then, screwed in place nut 33 guarantees screw rod 31 invariant positions, measure the height that screw rod 31 exceeds concrete pedestal 2, highly find the steel plate of respective thickness according to this, pad as backing plate, and is welded in the backing plate point on pre-buried steel spare 5 on each concrete pedestal 2, adjustment height support bar 3 falls in pine again, thereby base plate 1 just can remain on inverted camber position up to standard.
