Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0020] A method for vibrating an anti-collision formwork with vibrating rods inside concrete. Side formwork 12 is vertically fixed on the upper end of a concrete cushion or bottom formwork 13, and concrete 11 is filled between the side formwork. The head of the vibrating body of the vibrator is inserted into the concrete 11 inside, and the rotating flexible shaft at the tail stretches out of the concrete, and the motor is driven to vibrate the vibrating body of the vibrator to vibrate.
[0021] Concrete internal vibrator structure as attached figure 1 As shown, it includes a motor 1, a rotating flexible shaft 2, a connecting sleeve 3, and a vibrator body 4. There is an exciter in the head of the vibr...

The invention relates to a vibrating method for preventing a vibrating rod in concrete from bumping a formwork. A rotary flexible shaft limiting support at the tail portion of vibrator machine vibrating body outside the concrete is installed on a limiting support, the limiting support comprises vertical claws, horizontal fixing plates and semi-circular plates, semi-circular clamp plate structures are arranged in the middles of the horizontal fixing plates, the semi-circular plates are hinged to one side of each semi-circular clamp plate structure, the semi-circular plates and the semi-circular clamp plate structures of the horizontal fixing plate are oppositely buckled, the vertical claws are fixedly installed at two ends of each horizontal fixing plate, and the horizontal fixing plates on two sides of each semi-circular clamp plate structures symmetrically form 120-degree included angles. The vibrating method for preventing the vibrating rod in the concrete from bumping the formwork is good in integrity and convenient to seal, dismount and clear and has good sociality and economical efficiency, and the construction defects influencing the appearance quality, such as honeycombs, pitted surfaces, reinforcing bar exposure, edge failure, stone exposure, bonding and air bubbles in concrete construction, are decreased.
Description
technical field [0001] The invention belongs to the field of transmission line foundation construction and building construction, in particular to a method for vibrating an anti-collision formwork with vibrating rods inside concrete. Background technique [0002] During the construction of the transmission line foundation, in the large step foundation construction, the distance between the steel bar and the formwork is relatively large. According to the requirements of the construction specification, a vibrating rod needs to be inserted into the cast-in-place concrete for construction. The vibrating rod must not touch the formwork or the steel bars during the operation. At present, in places where the steel bars are densely packed and at the corners of the formwork, it is still the case of manual tamping with iron brazing, which is prone to some construction defects such as honeycomb, pockmarked surface, exposed tendons, gnawed edges, exposed stones, sticky skin, and air bub...
