Abstract
The utility model relates to a temporary locking device of decking and girder steel, including arranging locking roof beam (1) at decking (6) upper surface, fixing at locking nut (5) at girder steel (7) top and screw rod (2) that locking nut (5) and locking roof beam (1) are connected respectively at both ends, screw rod (2) upper end is provided with adjusting nut (3) with screw rod (2) and locking roof beam (1) locking. Compared with the prior art, the utility model discloses can firmly retrain prefabricated decking tip and prevent to lift up, and have easy operation, the convenient advantage of dismouting.
Description
Technical Field
The utility model belongs to the technical field of the bridge building and specifically relates to a temporary locking device of decking and girder steel is related to.
Background
The prefabricated bridge deck can ensure the structural quality of concrete, and can realize the standardization and the rapidity of construction, but when the combined beam bridge is constructed, because the prestressed reinforcement is generally arranged above the section core, the end part of the prefabricated bridge deck can be lifted up during tensioning. There is a need for a device that can temporarily restrain a prefabricated bridge deck.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a temporary locking device of decking and girder steel in order to overcome the defect that above-mentioned prior art exists.
The purpose of the utility model can be realized through the following technical scheme:
the utility model provides a temporary locking device of decking and girder steel, is including arranging the locking roof beam at the decking upper surface, fixing at the locking nut at the girder steel top and pass the screw rod of locking roof beam, screw rod one end and locking nut threaded connection, the other end passes the locking roof beam, the screw rod upper end is provided with the adjusting nut with screw rod and locking roof beam locking.
Further, the locking nut is welded to the top of the steel beam.
Furthermore, the screw rod overcoat is equipped with the plastic sleeve, prevents that the screw rod from contacting with cast-in-place concrete, and the screw rod can be pulled out fast when demolising.
Further, a transverse handle is arranged at the top of the screw rod.
Furthermore, a notch is formed in the bridge deck, and the temporary locking device is arranged in the notch.
Further, the length of the locking beam is greater than the width of the slot.
The adjusting nut is used for adjusting the locking state between the locking beam and the prefabricated bridge deck slab, and when the screw and the locking nut are screwed, the locking beam and the prefabricated bridge deck slab can be pressed tightly by screwing the adjusting nut, so that the displacement of the prefabricated bridge deck slab and the steel beam is restrained; the screw can be unscrewed by a transverse handle at the top when the locking is released.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the end part of the prefabricated bridge deck can be firmly restrained, and the requirement that the end part of the prefabricated bridge deck is prevented from being lifted when the prestressed reinforcement is tensioned on the combined beam bridge is met;
2. the system is simple in composition, stable and reliable, simple to operate and convenient to disassemble and assemble.

Examples
A temporary locking device for a bridge deck and a steel beam comprises a locking beam 1 arranged on the upper surface of a bridge deck 6, a locking nut 5 fixed at the top of the steel beam 7 and a screw rod 2 penetrating through the locking beam 1, wherein one end of the screw rod 2 is in threaded connection with the locking nut 5, the other end of the screw rod 2 penetrates through the locking beam 1, and an adjusting nut 3 for locking the screw rod 2 and the locking beam 1 is arranged at the upper end of the screw rod 2. The locking nut 5 is welded on top of the steel beam 7. The screw rod 2 is sleeved with the plastic sleeve 4, so that the screw rod 2 is prevented from contacting cast-in-place concrete, and the screw rod 2 can be quickly pulled out during dismantling. The top of the screw rod 2 is provided with a transverse handle. The bridge deck 6 is provided with a notch 8, and the temporary locking device is arranged in the notch 8. The length of the locking beam 1 is greater than the width of the slot 8.
The adjusting nut 3 is used for adjusting the locking state between the locking beam 1 and the prefabricated bridge deck 6, and after the screw rod 2 and the locking nut 5 are screwed, the locking beam 1 and the prefabricated bridge deck 6 can be tightly pressed by screwing the adjusting nut 3, so that the displacement of the prefabricated bridge deck 6 and the steel beam 7 is restrained; the screw 2 can be unscrewed by a lateral handle at the top when the locking is released.
The embodiments described above are intended to facilitate the understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention according to the disclosure of the present invention.
