Embodiment Construction
[0041] Attached to the following Figure 1-4 This application will be described in further detail.
[0042] The embodiment of the present application discloses a production method for improving the grouting density of a prestressed concrete beam, which is realized by using a vibrating component. refer to figure 1 and figure 2 , the vibrating assembly includes a vibrating plate 2 , the vibrating plate 2 is detachably fixed on the beam formwork 1 by screws 24 , and a vibration motor 21 is fixed on the side of the vibrating plate 2 away from the beam formwork 1 . The side of the vibration plate 2 facing the beam formwork 1 is provided with a lifting groove 22 along the vertical direction, and a lifting block 311 is slidably arranged in the lifting groove 22. The cross section of the lifting groove 22 in the horizontal direction is T-shaped, and one end of the lifting groove 22 It penetrates through the top wall of the vibration plate 2 and the other end penetrates through the...

The invention relates to a production method for improving grouting compactness of a prestressed concrete beam, which is applied to the technical field of concrete pouring and comprises the following steps: S1, building a beam template; s2, a plurality of vibrating assemblies are detachably and fixedly connected with the beam formwork, and grouting is conducted in the beam formwork through a grouting machine; s3, when the height of the concrete slurry reaches the standard elevation, the vibrating assembly controls the grouting machine to be closed and vibrates the concrete slurry; and S4, after vibration is finished, the vibration assembly is disassembled, and the concrete slurry is subjected to trowelling, press polish and maintenance treatment in sequence. The concrete slurry vibrating device has the effect of conveniently vibrating concrete slurry.
Description
technical field [0001] The present application relates to the technical field of concrete pouring, and in particular, to a production method for improving the grouting density of prestressed concrete beams. Background technique [0002] At present, when concrete is poured, air bubbles are often mixed in the concrete slurry, which will lead to the appearance of honeycomb pitting and other phenomena after the concrete is solidified. [0003] In the related art, when the prestressed concrete beam is poured, the staff will use the vibrating rod to extend into the concrete slurry to vibrate. During the vibration, some air bubbles in the concrete slurry will rise and escape from the surface of the concrete slurry. . [0004] In view of the above-mentioned related technologies, the inventor believes that it is necessary to wait for the height of the concrete slurry to reach the elevation line, and then manually turn off the grouting machine and start the vibrating rod to vibrate t...
