Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge anti-collision wall construction, in particular to a detachable deformation joint formwork for bridge anti-collision walls. Background Technique
[0002] The deformation joint formwork for bridge anti-collision walls is a special formwork designed specifically for bridge anti-collision walls, used to reserve a deformation joint space in the anti-collision wall to adapt to the structural deformation of the bridge caused by factors such as temperature changes, load effects, concrete shrinkage and creep, and foundation settlement.
[0003] For the existing deformation joint formwork of bridge anti-collision walls, after the concrete is poured between the formworks and fixed in the pouring area, the poured concrete is formed, and a deformation joint space is reserved. However, since air bubbles, honeycombs, pitted surfaces and other surface defects are likely to occur after the concrete is poured between the formworks, the surface quality of the deformation joints of the bridge anti-collision walls is reduced.
[0004] Therefore, a detachable deformation joint formwork for bridge anti-collision walls has been developed, which can vibrate the outer formwork and the end face formwork, increase the compactness of the concrete, and improve the surface quality of the concrete. Content of the Utility Model
[0005] In order to overcome the shortcomings of the existing deformation joint formwork for bridge anti-collision walls, where air bubbles, honeycombs, pitted surfaces and other surface defects are likely to occur after the concrete is poured between the formworks, reducing the surface quality of the deformation joints of the bridge anti-collision walls, the utility model provides a detachable deformation joint formwork for bridge anti-collision walls that can vibrate the outer formwork and the end face formwork, increase the compactness of the concrete, and improve the surface quality of the concrete.
[0006] A detachable deformation joint formwork for bridge anti-collision walls includes outer formworks, arc-shaped buckles, end face formworks, merging components, clamping components, end tightening components and vibration mechanisms. There are two front and rear outer formworks, and a plurality of arc-shaped buckles are connected to the upper sides of the outer formworks. There are two left and right end face formworks, which are respectively located on the left and right sides of the outer formworks. A merging component is arranged between the upper parts of the outer formworks, and a clamping component is also arranged between the upper parts of the outer formworks. End tightening components are arranged between the outer formworks and the end face formworks, and vibration mechanisms capable of vibrating the poured concrete are arranged on the outer formworks.
[0007] Furthermore, the merging component includes first bolts and first clamping plates. There are two left and right first bolts, which are both located between the outer formworks. A plurality of first clamping plates are threadedly connected to the first bolts, and the first clamping plates are all in contact with the adjacent outer formworks.
[0008] Furthermore, the clamping assembly includes an upper plate, a lower plate, a second bolt, and a spirit level. A plurality of lower plates are connected to the upper side of the outer template, and the upper plates are connected between two adjacent lower plates by two front and rear second bolts. Spirit levels are connected to the upper sides of the upper plates.
[0009] Furthermore, the end-tightening assembly includes a second clamping plate and a third bolt. A plurality of third bolts are clamped on the left and right sides of the outer template, and two left and right second clamping plates are threadedly connected to the third bolts.
[0010] Furthermore, the oscillation mechanism includes a middle partition board, a central spring, a pull column, and a percussion plate. Middle partition boards are connected to the mutually remote sides of the middle part of the outer template. Pull columns are slidably connected to the upper and lower parts of the middle partition boards. Central springs are connected between the left and right parts of the pull columns and the connected middle partition boards. A plurality of percussion plates are connected to the mutually remote sides of the upper and lower parts of the outer template.

[0012] The beneficial effects of the present utility model are as follows: 1. By pulling the pull column to move, the pull column strikes the percussion plate, and then the pull column is released. Due to the action of the central spring, the pull column resets, causing the pull column to strike the percussion plate again, achieving the effect of being able to vibrate the outer template and the end face plate, increasing the compactness of the concrete, and improving the surface quality of the concrete.
[0013] 2. By pushing the scraper to move on the outer template, the scraper scrapes the concrete into the hopper, achieving the effect of being able to conveniently clean the concrete on the outer template and preventing the concrete from solidifying. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] A detachable deformation joint template for a bridge anti-collision wall, as Figures 1-6 shown, includes an outer template 1, an arc-shaped buckle 2, an end panel 3, a merging component 4, a clamping component 5, an end tightening component 7 and an oscillation mechanism 8. There are two front and rear outer templates 1, and four arc-shaped buckles 2 are connected to the upper sides of the outer templates 1. There are two left and right end panels 3, and the end panels 3 are respectively located on the left and right sides of the outer templates 1. A merging component 4 is provided between the upper parts of the outer templates 1, a clamping component 5 is also provided between the upper parts of the outer templates 1, an end tightening component 7 is provided between each outer template 1 and the end panel 3, and an oscillation mechanism 8 is provided on each outer template 1.
[0023] As Figures 1-3 shown, the merging component 4 includes a first bolt 41 and a first clamping plate 42. There are two left and right first bolts 41, and the first bolts 41 are both located between the outer templates 1. Four first clamping plates 42 are threadedly connected to each first bolt 41, and the first clamping plates 42 are all in contact with the adjacent outer templates 1.
[0024] As Figures 1-3 shown, the clamping component 5 includes an upper plate 51, a lower plate 52, a second bolt 53 and a level gauge 6. Three lower plates 52 are connected to the upper sides of the outer templates 1, and an upper plate 51 is connected between the adjacent two lower plates 52 by two front and rear second bolts 53, and a level gauge 6 is connected to the upper side of each upper plate 51.
[0025] As Figures 1-3 shown, the end tightening component 7 includes a second clamping plate 71 and a third bolt 72. Four third bolts 72 are clamped on the left and right sides of the outer templates 1, and two left and right second clamping plates 71 are threadedly connected to each third bolt 72.
[0026] As Figure 1 , Figure 4 and Figure 5 shown, the vibration mechanism 8 includes a middle partition plate 81, a central spring 82, a pull column 83 and a percussion plate 84. Middle partition plates 81 are connected to both sides of the middle part of the outer template 1 that are far away from each other. Pull columns 83 are slidably connected to both the upper and lower parts of the middle partition plate 81. Central springs 82 are connected between the left and right parts of the pull column 83 and the connected middle partition plate 81. Fourteen percussion plates 84 are connected to both sides of the upper and lower parts of the outer template 1 that are far away from each other. The pull column 83 is in contact and cooperation with the adjacent percussion plate 84.
[0027] When using the present utility model, first place the outer template 1 together in the construction area of the deformation joint of the bridge anti-collision wall. The arc-shaped buckle 2 is used for hoisting the outer template 1. Through the cooperation of the first bolt 41 and the first clamping plate 42, the outer template 1 is fixed. Then, the upper plate 51 is fixed to the lower plate 52 through the second bolt 53, so that the upper plate 51 contacts the upper side of the outer template 1 to clamp the outer template 1. The level 6 can be used to observe whether the outer template 1 is horizontal. Then, the end face plate 3 is fixed to both sides of the outer template 1 through the second clamping plate 71 and the third bolt 72. Then, concrete is injected between the outer template 1 and the end face plate 3, so that the concrete is formed between the outer template 1 and the end face plate 3. After the concrete is formed, the first bolt 41 is removed, and then the second bolt 53 and the third bolt 72 are removed. Then, the end face plate 3 is lifted away from the concrete by a loader, so as to reserve a deformation joint space in the anti-collision wall. After injecting the concrete between the outer template 1 and the end face plate 3, the pull column 83 can be pulled to move, so that the pull column 83 strikes the percussion plate 84, and then the pull column 83 is released. Through the action of the central spring 82, the pull column 83 is reset, so that the pull column 83 strikes the percussion plate 84 again, thereby playing a role in enabling the outer template 1 and the end face plate 3 to vibrate, increasing the compactness of the concrete, and improving the surface quality of the concrete.
[0028] As Figure 1 and Figure 6 shown, it further includes a cleaning mechanism 9. The cleaning mechanism 9 includes a hopper 91 and a scraper 92. Twelve scrapers 92 are slidably connected to both sides of the outer template 1 that are far away from each other. The lower sides of the scrapers 92 are slidably and detachably connected to the hopper 91.
[0029] By using the cleaning mechanism 9 of the present device, the concrete on the outer template 1 can be cleaned. After the concrete falls onto the outer template 1, the scraper 92 can be pushed to move on the outer template 1, so that the scraper 92 scrapes the concrete into the hopper 91, thereby playing a role in facilitating the cleaning of the concrete on the outer template 1 and avoiding the solidification of the concrete. After cleaning, the hopper 91 can be removed to recycle the concrete.
