Description

Technical Field

[0001] The utility model relates to the technical field of crack repair, and more specifically to a road and bridge construction crack reinforcement structure. Background Art

[0002] With the rapid development of cities, municipal road and bridge construction has become more and more frequent. After long-term use, some structures of current bridges and roads will gradually age or be damaged. After vehicles pass by, cracks will appear on the surface of the road.

[0003] In order to ensure the safety of roads, the traditional method of crack repair is now used. Since it is impossible to directly install steel bars at the cracks to provide support, concrete can only be used to directly pour the cracks. Although direct pouring of concrete can fill the cracks, the tensile force of concrete on both sides of the cracks is small. During the subsequent use of vehicles running over them, the cracks will still expand. The repair effect is poor and requires constant maintenance, affecting normal use. A solution is proposed below to address the above problems. Utility Model Content

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. This solution uses expansion bolts on the base plate to expand the expansion sleeve, thereby fixing the base plate on the road surface on both sides of the crack. According to the width of the crack, the position of the bracket on the base plate is adjusted to ensure that the connecting piece passes through the crack. At the same time, since the crack is irregular, the position of the bracket can be adjusted to adapt to the change in crack width. The crack is then filled with concrete. Concrete is used to fill the crack, and the connecting piece is used to prevent the crack from being deformed by stress again, thereby ensuring the service life after repair.

[0015] 2. The fixing rod is used to cooperate with the bracket, and there is a gap between the fixing rod and the bracket, so that the fixing rod and the bracket can move, with a certain buffer amount, which facilitates the cooperation between the bracket and the corresponding socket.

[0019] 6. The support plate supports the top plate, and the fixing port on the top plate cooperates with the top rod to support and fix the top of the pull rod, thereby ensuring the stability of the force at both ends of the pull rod and ensuring the stability of the pull rod's fixation to the connecting parts.

DETAILED DESCRIPTION

[0029] Embodiment 1:

[0030] See also Figure 1-6 A road and bridge construction crack reinforcement structure includes a symmetrically arranged base plate 1, four through-holes 4 are installed on the base plate 1, the four through-holes 4 are arranged in a rectangular array, and the four through-holes are respectively located at the four corners of the base plate 1, and expansion bolts 5 are penetrated inside the through-holes 4. The expansion bolts 5 are located at one end of the bottom of the base plate 1 and are sleeved with an expansion sleeve 6 on the outside. The expansion bolts 5 are threaded at one end of the top of the base plate 1 and are matched with a nut 7.

[0031] By rotating the nut 7, the nut 7 can be threadedly connected to the expansion bolt 5, so that the expansion bolt 5 can be pulled to move in the direction close to the nut 7, so that the expansion bolt 5 will pull the expansion sleeve 6 to expand, and the expansion of the expansion sleeve 6 will fix it to the road surface next to the crack. The use of four expansion sleeves 6 can ensure the stability of the fixation of the base plate 1 and reduce shaking.

[0032] A support plate 17 is installed on the bottom plate 1, and several support plates 17 are C-shaped. The support plates 17 are fixed on the bottom plate 1, and the openings of the support plates 17 on the two bottom plates 1 correspond to each other. A top plate 18 is arranged on the support plate 17, and several groups of mounting openings 10 are evenly opened on the bottom plate 1, and each group of mounting openings 10 includes several sockets 11, and the sockets 11 are arranged in a straight line, and the straight line where the centers of the sockets 11 are located is the same as the opening direction of the support plate 17, so as to ensure that the length of the connecting member 2 extending out of the support plate 17 can be adjusted, that is, the distance between the two bottom plates 1 is adjusted, so as to adapt to cracks of different widths, and several groups of fixing openings 19 corresponding to the mounting openings 10 are opened on the top plate 18, and the fixing openings 19 have the same structure as the mounting openings 10.

[0033] A plurality of brackets 3 are installed between the bottom plate 1 and the top plate 18, and the number of the brackets 3 corresponds to the number of groups of the mounting openings 10. The brackets 3 include a pull rod 14, an insert rod 12 and a tensioner 13. The insert rod 12 is fixed at one end of the pull rod 14, and the insert rod 12 is plugged into the mounting opening 10. A top rod 20 is fixedly connected to the top of the pull rod 14, and the top rod 20 corresponds to and intersperses with the fixing opening 19. By using the top rod 20 and the fixing opening 19 in combination, and the insert rod 12 and the mounting opening 10 in combination, both ends of the pull rod 14 can be limited at the same time to ensure the support of the pull rod 14 and improve the force.

[0034] Through the cooperation of the mounting port 10 and the fixing port 19, the two ends of the bracket 3 can be connected, and the design of the multiple sockets 11 can adjust the position of the bracket 3, thereby adjusting the distance between the two bottom plates 1 to adapt to cracks of different widths. The symmetrical arrangement of the mounting port 10 and the fixing port 19 can ensure that the two ends of the bracket 3 are fixed at the same time, thereby ensuring the stability of the force applied to the bracket 3.

[0035] A connecting piece 2 is installed between the two base plates 1, and both ends of the connecting piece 2 are located inside the openings of the two support plates 17. The connecting piece 2 includes a connecting rod 8 and a fixing rod 9. Two fixing rods 9 are provided, and the fixing rod 9 is annular. One end of the two fixing rods 9 is fixedly connected to the two ends of the connecting rod 8 respectively. The two fixing rods 9 are respectively sleeved on two corresponding pull rods 14, and the ring diameter of the fixing rod 9 is larger than the diameter of the pull rod 14, and the difference between the inner diameter of the ring of the fixing rod 9 and the diameter of the pull rod 14 is larger than the distance between adjacent sockets 11 in the same group. The fixing rod 9 and the pull rod 14 can move with a certain buffer amount, so that the connecting piece 2 can have corresponding fixing ports 19 and installation ports 10 to cooperate.

[0036] The tensioning member 13 is sleeved on the pull rod 14, and the tensioning member 13 and the insertion rod 12 are threadedly matched. The tensioning member 13 includes a clamping block 15, and the clamping block 15 is in the shape of a truncated cone with an upper surface larger than a lower surface. A through groove 16 is opened at the axis of the clamping block 15, and the through groove 16 is sleeved on the pull rod 14, and the through groove 16 and the pull rod 14 are threadedly matched. The bottom surface area of ​​the clamping block 15 will be smaller than the inner diameter of the ring portion of the fixing rod 9, and the top area of ​​the clamping block 15 is larger than the inner diameter of the ring portion of the fixing rod 9. The bottom area of ​​the clamping block 15 will be smaller than the inner diameter of the ring portion of the fixing rod 9, so that the clamping block 15 can be inserted between the ring portion of the fixing rod 9 and the pull rod 14. The top area of ​​the clamping block 15 is larger than the inner diameter of the ring portion of the fixing rod 9, which can ensure that the clamping block 15 can completely fix the pull rod 14 and the fixed position will not shake. The external fixed connection of the clamping block 15 is provided with a protrusion, which can facilitate the application of force to the clamping block 15, avoiding the problem that the truncated cone-shaped clamping block cannot apply force.

[0037] By rotating the protrusion, the protrusion will drive the clamping block 15 to rotate, and the clamping block 15 will drive the through groove 16 to rotate. The through groove 16 and the pull rod 14 are connected by threads. When the through groove 16 is rotated, the through groove 16 and the pull rod 14 will move relative to each other, thereby driving the clamping block 15 to move. The clamping block 15 moves along the pull rod 14, so that the clamping block 15 will move toward the ring part of the fixed rod 9, thereby fixing the fixed rod 9 and the pull rod 14 through the clamping block 15, thereby determining the position of the pull rod 14, so that the pull rod 14 can provide pulling force and supporting force to prevent the crack from continuing to expand.

[0038] The top plate 18 is provided with a pouring port 21 for convenient concrete pouring. The pouring port 21 facilitates the pouring of concrete between the top plate 18 and the bottom plate 1 to ensure the comprehensiveness of the concrete filling.

[0039] Working principle:

[0040] When in use, first drill corresponding holes on the bottom surfaces on both sides of the crack according to the position of the expansion sleeve 6 on the base plate 1, insert the corresponding expansion sleeve 6 into the hole, and by rotating the nut 7, the nut 7 pulls the expansion bolt 5 to move, the expansion bolt 5 will pull the expansion sleeve 6 to deform, and the expansion sleeve 6 will engage with the hole.

[0041] The fixing rods 9 at both ends of the connecting member 2 are sleeved on the two pull rods 14, and the two pull rods 14 are respectively arranged on the two base plates 1, and the pull rods 14 are arranged on the corresponding sockets 11 to ensure that the pull rods 14 are in a straight line state, and the protrusions are rotated, and the protrusions will drive the clamping blocks 15 to rotate, and the clamping blocks 15 will drive the through grooves 16 to rotate. The through grooves 16 and the pull rods 14 are connected by threads. When the through grooves 16 are rotated, the through grooves 16 and the pull rods 14 will move relative to each other, thereby driving the clamping blocks 15 to move, and the clamping blocks 15 move along the pull rods 14, so that the clamping blocks 15 will move toward the ring part of the fixing rod 9, thereby fixing the fixing rod 9 and the pull rods 14 through the clamping blocks 15, thereby determining the position of the pull rods 14, so that the pull rods 14 can provide pulling force and supporting force to prevent the cracks from continuing to expand.

[0042] Place the top cover on the support plate 17, and align the fixing port 19 on the top cover with the top rod 20, so that the top rod 20 is inserted into the fixing port 19. The cooperation of the fixing port 19 and the top rod 20 can stabilize the pull rod 14. Finally, weld the top plate 18 and the support plate 17 by welding, and finally fill the cracks with concrete. At the same time, concrete needs to be added between the bottom plate 1 and the top plate 18 through the filling port 21 to ensure that the concrete is fully filled and avoid hollowing. The filling port 21 can facilitate the pouring of concrete and ensure that the concrete is filled.
