Embodiment 1

[0035] The maintenance method for joint reinforcement in this embodiment comprises the following steps:

[0036] Step 1, such as figure 2 As shown, a notch 6 is made at the position of the hinge joint 2; specifically, at the top of the hinge joint 2; when opening the notch 6, part of the structure of the bridge is chiseled at the position of the hinge joint 2 until the reinforcement structure is exposed. Specifically, in this embodiment, the asphalt pavement 3 and part of the concrete pavement 4 of the bridge are chiseled at the hinge joint 2 until the steel mesh 5 in the concrete pavement 4 is exposed, that is, the concrete pavement is chiseled out. Concrete above the reinforcement mesh sheet 5 in layer 4 until the reinforcement mesh sheet 5 is exposed.

[0037] Step 2, drilling a vertical through hole in the hinged joint 2; the vertical through hole is opened in the middle of the hinged joint 2. The diameter of the vertical through hole is usually smaller than the width o...

Embodiment 2

[0048] Such as Figure 4As shown, the reinforcement maintenance device of this embodiment includes: an upper anchoring plate 7; a lower anchoring plate 8, and the upper anchoring plate 7 and the lower anchoring plate 8 are arranged at intervals; A plurality of slurry outlet holes 11 are provided on the peripheral surface, and each slurry outlet hole 11 communicates with the hollow part inwardly; the upper anchor plate 7 and the lower anchor plate 8 can be arranged in cooperation with the tie rods 9 respectively.

[0049] One end of the tie rod 9 is provided with a fixed nut 12, and the fixed nut 12 can be buckled on the upper anchor plate 7 or the lower anchor plate 8; the other end of the tie rod 9 is provided with a screw thread 13 and a fastening nut 14; One end of the tie rod 9 has a communication port 10, which makes the hollow structure communicate with the outside; the slurry outlet holes 11 are located between the fixed nut 12 and the thread 13 of the tie rod 9. Each ...

Abstract

The invention discloses a hinge joint reinforcing and maintaining method and a reinforcing and maintaining device. The hinge joint reinforcing and maintaining method comprises the following steps that1, forming a notch in the position of a hinge joint; 2, drilling a vertical through hole in the hinge joint; 3, arranging an upper anchoring plate at the notch, a lower anchoring plate is arranged atthe position, corresponding to the notch, below the plate beam, arranging a counter pull rod between the upper anchoring plate and the lower anchoring plate, the counter pull rod penetrates through the upper anchoring plate and the lower anchoring plate and is arranged in the vertical through hole, and then fastening the counter pull rod, the upper anchoring plate and the lower anchoring plate; 4, repairing the notch; 5, sealing the bottom of the hinge joint; and 6, injecting glue. The reinforcing maintenance device is additionally arranged, so that the transverse connection between the platebeams is enhanced, the stress state of the single beam is weakened, the vibration of the beam plate is avoided, and the cracking and discretization of the crack repairing adhesive are avoided.

Description

technical field [0001] The invention relates to a hinge joint reinforcement maintenance method and a reinforcement maintenance device. Background technique [0002] Such as figure 1 As shown, bridges or viaducts are often formed by connecting multiple plate girders, and each plate girder forms a transverse force connection through hinge joints, so that each plate girder forms a stressed whole. [0003] Damage to the hinged joints of the slab girder will cause damage to the slab. To repair the hinged joints, at this stage, the method of injecting glue or grouting into the hinged joints is mainly used to reinforce and repair the hinged joints. However, the injected colloid will crack and discretize, which will cause the loss of the glue injection effect; and the injection of colloid into the hinged seam will make the hinged seam unable to be repaired again. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a ...
