Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, the construction method of the tie beam between pier columns of the present invention sequentially comprises the following construction steps:
s1, when the pier stud 1 is constructed, a PVC pipe is pre-buried in each pier stud 1, and the PVC pipe is consistent with the supported bridge in the direction along the bridge; specifically, the two ends of the PVC pipe extend to the surface of the pier stud 1; during construction in the step, the specific embedded position of the PVC pipe is determined according to the position height of the tie beam and the total height of the steel bar 2, the I-steel a3, the I-steel b5, the I-steel c6 and the jack 4.
S2, inserting a steel bar 2 into the PVC pipe, wherein two ends of the steel bar 2 extend out of the pier stud 1; during actual operation, for the stick of steel 2 can run through the PVC pipe smoothly, can design the diameter of stick of steel 2 and slightly be lighter than the PVC pipe, nevertheless the size phase difference also can not be too big, otherwise the PVC pipe has lost the guide effect to stick of steel 2, and stick of steel 2 takes place to rock easily.
S3, erecting I-shaped steel a3 on the two steel bars 2 on the same side of the two adjacent pier studs 1; during specific construction, in order to ensure the stability of the I-steel a3 on the steel bar 2, the I-steel a3 can be fixed on the steel bar 2 by adopting common methods such as binding and the like.
S4, erecting two jacks 4 on the I-steel a 3; during specific construction, in order to ensure the stability of the jack 4 on the I-steel a3, the jack 4 can be fixed on the I-steel a3 by adopting common methods such as binding and the like.
S5, erecting I-shaped steel b5 on the two jacks 4 in the step S4, wherein the I-shaped steel b5 is parallel to the I-shaped steel a 3; during specific construction, in order to ensure the stability of the I-steel b5 on the jack 4, the I-steel b5 can be fixed on the jack 4 by adopting common methods such as binding and the like.
S6, erecting I-shaped steel c6 on two I-shaped steel b5 on two sides of two adjacent pier studs 1, wherein the I-shaped steel c6 is parallel to the steel bar 2, and a plurality of I-shaped steel c6 are uniformly distributed between the two pier studs 1.
S7, paving a bottom template 7 on the I-shaped steel c6, installing binding steel bars, and finally pouring concrete; here, the laying of the bottom form 7, the installation of the steel bars, and the pouring of the concrete all belong to the mature technologies in the field, and are not described herein again.
