Description
Technical field
It the utility model is related to Precast T-Beam technical field of construction, more particularly to a kind of pre-buried bearing steel plate in Precast T-Beam beam bottom
Longitudinal slope adjusting means.
Background technology
According to Precast T-Beam construction design drawing and related specifications requirement, after the beam body installation of Precast T-Beam, beam bottom
Pre-buried bearing steel plate (refers to pre-buried steel plate at beam body fulcrum, it is to increase the shock resistance of beam body and increase
The contact area of beam body stress point.That is existing for two monomer members faying faces for having support relation, it is anti-with bearing
The perpendicular steel plate of power, can all be bearing steel plate, and its effect is to ensure to transmit to even action caused by load.) have to
Keep level state is simultaneously brought into close contact with bearing.Therefore, during prefabrication of beam, it is desirable to which pre-buried bearing steel plate is formed and bridge
The opposite gradient of longitudinal slope is designed, if the regulation of pre-buried bearing steel plate longitudinal slope is inaccurate, bearing will be caused to bias after beam body installation, from
And cause bearing to be possible to too early and be damaged, the service life of bridge is had a strong impact on, the operation to bridge from now on causes very
Big potential safety hazard, and deal with suitable trouble.
In the prior art, the pre-buried bearing steel plate longitudinal slope adjusting method in Precast T-Beam beam bottom mainly include using reinforcing bar pad method,
Layer of sand pad method and wedge-shaped steel plate welding, wherein, reinforcing bar pad method is the longitudinal slope of the pre-buried bearing steel plate provided according to design,
The reinforcing bar of pad different-diameter below steel plate, by adjusting the position of reinforcing bar, steel plate is set to reach the longitudinal slope of design requirement；Layer of sand
Pad method is to lay sand bedding course in the lower section of steel plate before pre-buried bearing steel plate is installed, and the thickness of sand bedding course and the gradient are protecting
The exposed height and longitudinal slope for demonstrate,proving pre-buried bearing steel plate can meet design requirement.Before the installation of T beams, sand bedding course departs from steel plate, so as to
Ensure the installation quality of steel plate；The pre-buried bearing steel plate of design is divided into two by wedge-shaped steel plate welding, and one piece is horizontal steel plate,
One piece is wedge-shaped steel plate.To ensure the control accuracy of the pre-buried bearing steel plate longitudinal slope in beam bottom, first at pre-buried one piece of beam bottom and beam bottom
Horizontal steel plate, the one piece of thickness of longitudinal slope making then provided according to design, angle can meet the wedge-shaped steel plate of design requirement, then
Wedge-shaped steel plate and horizontal steel plate are welded, so as to reach the purpose of accurate control bearing steel plate setting angle.
But above-mentioned adjusting method has the disadvantage that：
(1) installation accuracy is poor：Using reinforcing bar pad method or layer of sand pad method can not effectively, be accurately controlled pre-buried branch
The longitudinal slope of seat steel plate, because in model sheetinstallat or T beam concreting processes, template is had unavoidably and collides pre-buried bearing steel plate
Or concrete inclines and falls to cause the impulsive force of steel plate steel plate to produce displacement, the longitudinal slope for causing originally to set changes；
(2) low construction efficiency：Need first to set reinforcing bar below pre-buried bearing steel plate using reinforcing bar pad method, pass through Mobile steel
The position of muscle adjusts the exposed thickness and longitudinal slope of pre-buried bearing steel plate, it is necessary to by constantly moving and measurement can be only achieved and set
Desired size and angle is counted, therefore efficiency of construction is relatively low；Layer of sand pad method needs first to lay sand bedding course below steel plate, by not
Disconnected measurement and layer of sand adjustment, finally ensure the thickness and angle of layer of sand.Therefore, efficiency of construction is equally relatively low；Wedge-shaped steel plate welds
Connection, although having saved the time of the pre-buried bearing steel plate longitudinal slope of adjustment, need to be increased by the independent processing wedged steel plate of design requirement
The weld interval added considerably beyond the supertronic time, and welding quality is not easy to ensure.
(3) quality control is difficult：During using wedge-shaped steel plate welding, before the installation of T beams or after installation must by horizontal steel plate and
Wedge-shaped steel plate welding is integral, because welding direction is vertical direction, therefore welding quality is difficult control.If installed in T beams
Weld again afterwards, due to the limitation of construction site, it more difficult to the welding quality of lower steel plate in guarantee；
(4) construction cost is high：Because reinforcing bar pad method and layer of sand pad method control accuracy are poor, therefore after increasing unavoidably
The expense of phase processing, therefore construction cost is higher；Wedge-shaped steel plate welding needs individually processing wedged steel plate and increase is welded together
Technique, therefore construction cost is higher.
Thus, the present inventor relies on experience and the practice for being engaged in relevant industries for many years, proposes that a kind of Precast T-Beam beam bottom is pre-buried
Bearing steel plate longitudinal slope adjusting means, the defects of to overcome prior art.
