Description
Technical field
A kind of pavement construction instrument is the utility model is related to, especially a kind of bituminous pavement paving elevation lofting tools.
Background technology
The road surface degree of balance is to weigh the important indicator of construction quality of pavement, and weighs pavement construction unit construction level height
Low deliberated index, excellent surface evenness can ensure a large amount of vehicle economy, it is comfortable, safely pass through, reduce the later stage and support
Shield and the expense of maintenance, improve service life of road surface.
Traditional asphalt pavement construction setting-out is to coordinate progress steel wire rope hanging wire highly to control by horizon rule and steel ruler, is entered
And spreading evenness is controlled, with the improvement of construction equipment, the present each level construction in road surface is used with Automatic Levelling function
Operating paver, the Automatic Levelling of paver typically have two ways：First, in road surface side using the high program control of steel wire rope guiding
Mode processed, mainly based on thickness control；Second, using the control mode that paves of the contactless balance two of paver, it is mainly
Based on being controlled with flatness.But this construction lofting method is in face of distance of constructing, the situation that data are more and horizontal slope is complicated
Under, easily there is the poor situation of the steel wire rope hanging wire elevation carrection degree of accuracy so that bitumen layer pave-load layer flatness and thickness are very
Difficulty is guaranteed, and in vehicle rolling with percussion repeatedly, flatness decays Fast Persistence, influences the security of driving
And comfortableness.
Therefore, steel wire rope hanging wire setting-out elevation accuracy how is controlled, and then controls asphalt mixture surfacing flatness and thickness
As a great problem of construction.
The content of the invention
The utility model solves distance of constructing in the prior art, and traditional horizon rule coordinates with steel ruler, easily occurs
The defects of steel wire rope hanging wire elevation carrection degree of accuracy is poor, and bitumen layer pave-load layer flatness and thickness hardly result in guarantee, there is provided
A kind of bituminous pavement paving elevation lofting tools, steel wire rope hanging wire setting-out is carried out using orthogonal montant and cross bar,
One people is operable, and cross bar can guarantee that vertical with montant, adjust perpendicularity without artificial, control is more convenient.
Concrete technical scheme of the present utility model is：A kind of bituminous pavement paving elevation lofting tools, including montant, are nested with
In the cross bar on montant, cross bar can adjust height, the vertical montant of cross bar with respect to montant, and lofting tools also include a calibration cross bar water
The level(l)ing bubble of Pingdu.Montant is supported in ground and support rail makes cross bar keep level, and cross bar is equivalent to horizon rule, control horizontal stroke
The height of bar, you can the height of control steel wire rope hanging wire, and then steel wire rope guiding is completed, and it is easy to operate, between cross bar and montant
Perpendicularity, without manual control；The level of cross bar is calibrated by level(l)ing bubble.
Preferably, montant is cylindrical bar, the appearance of montant is provided with size scale.It is by the size scale on montant
Adjustable cross bar is adjusted without steel ruler with respect to the height of ground reference position, easy to operate.
Preferably, one end of cross bar is connected with sleeve, sleeve gap is placed on montant, and locking screw is provided with sleeve
Nail.Vertical between cross bar and montant is realized by sleeve, lock-screw energy locking sleeve and montant.
Preferably, the lower side of cross bar and the axis perpendicular of sleeve, and the lower surface of the lower side of cross bar and sleeve
In same plane.
Preferably, level(l)ing bubble is horizontal bubble, horizontal bubble is arranged on cross bar, and horizontal bubble keeps same with cross bar
One is horizontal.The levelness for adjusting horizontal bubble is the levelness of adjustable cross bar.
The both sides of montant preferably, horizontal bubble and cross bar are placed in.
Preferably, the side where horizontal bubble is connected with balancing weight, horizontal bubble is connected with balancing weight, balancing weight
It is equal with respect to moment of torsion caused by montant with cross bar with respect to moment of torsion caused by montant.Balancing weight is just offset cross bar and produced with respect to montant
Moment of torsion, avoid sleeve with respect to montant deflect, cause cross bar tilt or sleeve clamping stagnation.
Preferably, level(l)ing bubble also includes a horizontal bubble for being arranged at montant top.
Preferably, the top of montant is hinged with handle ring.
Preferably, the lower end of montant is set in coniform.
The beneficial effects of the utility model are：Montant is supported in ground and support rail makes cross bar keep level, cross bar phase
When the height in horizon rule, controlling cross bar, you can the height of control steel wire rope hanging wire, and then complete steel wire rope guiding, operation side
Just, the perpendicularity between cross bar and montant, without manual control；The level of cross bar is calibrated by level(l)ing bubble.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the utility model；
In figure：1st, montant, 2, cross bar, 3, lock-screw, 4, sleeve, 5, handle ring, 6, balancing weight, 7, horizontal bubble.
Embodiment
