Abstract

This utility model relates to a protective wrapping device for dismantling old bridge piers, comprising arc-shaped plates and clamps. The arc-shaped plates are symmetrically arranged on both radial sides of the pier. A rubber pad is fixedly connected to the inner circumferential surface of the arc-shaped plates, and the inner circumferential surface of the rubber pad abuts against the outer circumferential surface of the pier. The clamps tightly hold the two arc-shaped plates to the pier. This protective wrapping device effectively protects the pier to be preserved from top to bottom along its circumference, reducing the risk of mechanical damage to the pier from the breaking or falling of the box girder.

Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a protective wrapping device for dismantling old bridge piers. Background Technology

[0002] Due to the design requirements of the new project, some piers need to be retained and extended for reuse. In existing technology, workers mark the cutting elevation on the outer surface of the piers and cut off the unwanted portions above the elevation. There is no protective device for the retained portions of the piers. If the box girder at the top of the original pier breaks or falls, it can mechanically scrape and damage the piers that need to be retained. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] This utility model discloses a protective wrapping device for dismantling old bridge piers.

[0020] Reference Figure 1-4 The protective device for dismantling old bridge pier 1 includes an arc-shaped plate 2 and a clamp 3. The arc-shaped plate 2 is symmetrically arranged on both sides of the radial direction of the pier 1. A rubber pad 4 is fixedly connected to the inner circumferential surface of the arc-shaped plate 2. The inner circumferential surface of the rubber pad 4 abuts against the outer circumferential surface of the pier 1 to increase the friction between the arc-shaped plate 2 and the pier 1 and improve the stability of the fit between the arc-shaped plate 2 and the pier 1. The clamp 3 holds the two arc-shaped plates 2 tightly to the pier 1.

[0021] The arc-shaped plate 2 includes a middle plate 21 and an end plate 22 along the axial direction of the pier column 1. The end plate 22 is located at both ends of the middle plate 21 in the axial direction. There is a clamp 3 on the middle plate 21 and the end plate 22, and there is a rubber pad 4 on the middle plate 21 and the end plate 22.

[0022] A first limiting arc plate 5 is provided on the outer peripheral wall of the middle plate 21. The first limiting arc plate 5 is located on both sides of the corresponding clamp 3 in the width direction. The first limiting arc plate 5 positions the clamp 3 on the middle plate 21.

[0023] A second limiting arc plate 6 is provided on the outer peripheral wall of the end plate 22. The second limiting arc plate 6 is located on both sides of the corresponding clamp 3 in the width direction. The second limiting arc plate 6 positions the clamp 3 on the end plate 22.

[0024] The end plate 22 is coaxially connected to the guide plate 7 on the side near the middle plate 21. The middle plate 21 has guide grooves 8 at both ends in the axial direction for the guide plate 7 to slide, so that the length of the arc plate 2 is adjustable and can adapt to piers 1 of different heights.

[0025] The guide arc plate is rounded at one end near the guide groove 8 to improve the smoothness of sliding between the end plate 22 and the middle plate 21.

[0026] In this embodiment, the arc plate 2, the guide plate 7, the first limiting arc plate 5, and the second limiting arc plate 6 are all made of wood, and the clamp 3 is made of steel.

[0027] The width of the end plate 22 is smaller than the width of the middle plate 21. The inner circumferential surface of the middle plate 21 is flush with the inner circumferential surface of the end plate 22, so that the inner circumferential surfaces of the middle plate 21 and the end plate 22 can be pressed against the outer circumferential surface of the pier 1. The guide plate 7 plays a radial protection role for the corresponding position of the pier 1, preventing side-falling objects from hitting the pier 1 and causing damage to the pier 1.

[0028] With the protection of the protective device, the circumference of the pier 1 that needs to be retained can be effectively protected from top to bottom, reducing the possibility of mechanical damage to the pier 1 that needs to be retained when the box girder breaks or falls.

[0029] The implementation principle of the protective wrapping device for dismantling an old bridge pier 1 in this embodiment of the application is as follows: First, the bottom surface of the end plate 22 located at the bottom is attached to the ground, so that the rubber pads 4 on the inner circumference of the two end arc plates at the bottom are attached to the outer circumference of the pier 1. Then, the two end arc plates at the bottom are held tightly to the pier 1 with the clamp 3. Then, align the guide groove 8 at the bottom of the middle plate 21 with the guide plate 7 at the bottom end plate 22, so that the guide plate 7 at the bottom end plate 22 is inserted into the guide groove 8 at the bottom of the middle plate 21. Then align the guide plate 7 at the top end plate 22 with the guide groove 8 at the top of the middle plate 21, so that the guide plate 7 at the top end plate 22 is inserted into the guide groove 8 at the top of the middle plate 21, so that the top surface of the top end plate 22 is flush with the cutting elevation. Then, make the rubber pads 4 on the inner circumference of the two end arc plates at the top fit with the outer circumference of the pier 1. Then, use the clamp 3 to hold the two end arc plates at the top tightly to the pier 1. Finally, the middle plate 21 is moved to the middle of the pier 1, and the two middle arc plates are tightly bound to the pier 1 with the clamp 3, so that the circumference of the pier 1 that needs to be retained can be effectively protected from top to bottom.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
