Abstract
Description
Technical Field

[0028] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0029] like Figure 1-9 As shown, the utility model provides a bridge wet joint reinforcement structure, including a prefabricated beam body 1; the number of prefabricated beam bodies 1 is two groups, and the prefabricated beam bodies 1 are symmetrically distributed on the left side and the right side of the concrete wet joint 2; it also includes a reinforcement device 3; the reinforcement device 3 includes a fixed support plate 301, a movable bearing plate 302, a fixed seat 303, an adjustment sleeve 304, an adjustment threaded rod 305, a reinforcement support plate 306, a support threaded rod 307, a support sleeve 308, a fixing sleeve 309, an anchor bolt 310 and a movable seat 311; the fixed support plate 301 is fixedly connected to the prefabricated beam body 1 by the anchor bolt 310; the reinforcement support plate 306 is welded to the fixed support plate 301; the number of the fixed seat 303 is four The movable support plate 302 is provided with a plurality of movable sleeves 308, each of which is provided with a plurality of movable sleeves 309, each of which is provided with a plurality of movable sleeves 309, each of which is provided with a plurality of movable sleeves 309, each of which is provided with a plurality of movable sleeves 308 ...
[0030] When the utility model is performing reinforcement and installation work on the wet joint of the bridge, the bridge construction personnel use a wrench to rotate the adjusting sleeve 304. Since the two sets of symmetrically distributed adjusting threaded rods 305 are respectively engaged with the positive thread end and the reverse thread end on the inner side of the adjusting sleeve 304, the adjusting sleeve 304 drives the two sets of adjusting threaded rods 305 to telescopically move left and right along the adjusting sleeve 304. According to the spacing distance between the two sets of prefabricated beam bodies 1, the telescopic length of the two sets of adjusting threaded rods 305 is adjusted until the adjusting threaded rods 305 drive the V-shaped fixed support plate 301 to fit the outer side of the prefabricated beam body 1, and then the anchor bolts 310 are inserted into all the through holes of the fixed support plate 301, and the anchor bolts 310 are driven into the interior of the prefabricated beam body 1, so that the fixed support plate 301 is stably fixed on the prefabricated beam body 1, and then the adjusting sleeve 30 is screwed again. 4. The two sets of adjusting threaded rods 305 are used to tension and pull the two sets of symmetrically distributed fixed support plates 301 to reduce the lateral extrusion load of the concrete wet joint 2 and prevent the concrete wet joint 2 from undergoing excessive lateral deformation. If the fixed support plate 301 is still unable to cover and support the lower side of the concrete wet joint 2 after the fixing is completed, the bridge construction personnel can use a wrench to turn the support sleeve 308. Since the support threaded rod 307 and the inner side threads of the support sleeve 308 are internally meshed with each other, the support sleeve 308 drives the support threaded rod 307 to extend, and the support sleeve 308 is driven by the fixed sleeve 309 to slide out of the open groove on the upper side of the fixed support plate 301 until the two sets of movable bearing plates 302 completely cover the lower side of the concrete wet joint 2, completing the load-bearing reinforcement work of the concrete wet joint 2.
[0031] In the disclosed embodiment, the adjusting sleeve 304 is a cylindrical barrel structure that passes through the left and right sides, and the inner side of the cylindrical barrel structure is provided with a forward threaded end and a reverse threaded end. The adjusting threaded rod 305 on the left side is meshed and connected to the forward threaded end of the inner side of the adjusting sleeve 304, and the adjusting threaded rod 305 on the right side is meshed and connected to the reverse threaded end of the inner side of the adjusting sleeve 304. The outer side of the adjusting sleeve 304 is provided with a hexahedral structure, which is convenient for bridge construction personnel to adjust the opposite telescopic lengths of the two sets of adjusting threaded rods 305 by rotating the adjusting sleeve 304 with a wrench.
[0032] In the disclosed embodiment, there are two groups of support sleeves 308, and an annular ring plate is provided on the outer side of the support sleeve 308. The inner side of each group of support sleeves 308 is provided with a thread, and the outer side threads of the two groups of support threaded rods 307 are respectively meshed and connected with the inner side threads of the two groups of support sleeves 308. During the rotation of the support sleeve 308, the support sleeve 308 drives the support threaded rod 307 to telescope and move, thereby changing the combined length of the support sleeve 308 and the support threaded rod 307, and pushing the movable bearing plate 302 to adjust the bearing position according to the width of the concrete wet joint 2.
[0033] In the disclosed embodiment, the fixed sleeve 309 is a barrel structure with one end open, and the inner side surface of the barrel structure of the fixed sleeve 309 is provided with an annular groove, and the annular ring plate of the support sleeve 308 is embedded in the annular groove of the fixed sleeve 309. The fixed sleeve 309 pulls the supporting sleeve 308 through the rotating interlocking structure of the annular groove and the annular ring plate of the supporting sleeve 308, while ensuring that the supporting sleeve 308 rotates in the barrel structure of the fixed sleeve 309, thereby realizing the threaded engagement adjustment action of the supporting sleeve 308 on the supporting threaded rod 307.
[0034] In the disclosed embodiment, the reinforced support plate 306 is a triangular structure, and the reinforced support plate 306 is made of Q460 high-strength steel. The structural stability of the triangle is combined with the anti-deformation properties of the high-strength steel to enable the fixed support plate 301 to stably support the concrete wet joint 2, thereby preventing the concrete wet joint 2 from deforming and cracking due to vertical pressure.
[0035] In the disclosed embodiment, there are two groups of movable bearing plates 302, and the movable bearing plates 302 are symmetrically distributed on the left and right sides. Long convex keys are provided on the front and rear sides of the movable bearing plates 302, and the upper side surface of each group of movable bearing plates 302 is provided with four groups of long through grooves that pass through from top to bottom. The four groups of through grooves of the movable bearing plates 302 are respectively opposite to the four groups of through holes on the upper side surface of the fixed support plate 301, and the anchor bolts 310 are inserted into the through holes of the fixed support plate 301 and the through grooves of the movable bearing plates 302 from bottom to top, so that the fixed support plate 301 is fixed to the prefabricated beam body 1 through the anchor bolts 310, and the movable bearing plate 302 can slide flexibly on the fixed support plate 301.
[0036] In the disclosed embodiment, there are two groups of fixed support plates 301, and each group of fixed support plates 301 is a V-shaped folded plate structure. The V-shaped folded plate contour of the fixed support plate 301 fits with the outer side contour of the prefabricated beam body 1. The fixed support plate 301 is provided with a through hole, and the anchor bolts 310 are inserted into the through holes of the fixed support plate 301, so that the fixed support plate 301 is firmly fixed on both sides of the prefabricated beam body 1 through the anchor bolts 310. The upper side surface of the fixed support plate 301 is provided with an open groove, and the groove wall inside the open groove is provided with a sliding groove. The convex key of the movable bearing plate 302 is embedded in the inner side of the sliding groove of the fixed support plate 301, so that the movable bearing plate 302 can be stably displaced along the sliding groove of the fixed support plate 301.
[0037] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The anchor bolt 310 used above is a common device on the market. When it is purchased and used, it only needs to be connected according to the instruction manual purchased together, so it will not be repeated here.
[0038] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
