For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0026] The embodiment of the present application provides a joint device for a bridge deck downpipe, as Figures 1 to 6 shown. The joint device for the bridge deck downpipe includes a fixed pipe 1, a plurality of telescopic mechanisms 2, and a plurality of adjusting mechanisms 3. The fixed pipe 1 is provided with a plurality of pipe orifices. One ends of the plurality of telescopic mechanisms 2 are respectively connected to the corresponding pipe orifices, and the other ends are respectively connected to the corresponding downpipes 6. The plurality of telescopic mechanisms 2 can be telescoped along their axial directions. The plurality of adjusting mechanisms 3 are rotatably arranged in the circumferential direction of adjacent telescopic mechanisms 2 and are rotatably connected to the outer wall of the fixed pipe 1, and are configured to adjust the strength of the telescopic mechanisms 2.
[0027] Specifically, the fixed pipe 1 can be a two-way pipe, a three-way pipe, or a four-way pipe. When the fixed pipe 1 is a two-way pipe, the corresponding telescopic mechanisms 2 are two. When the fixed pipe 1 is a three-way pipe, the corresponding telescopic mechanisms 2 are three. When the fixed pipe 1 is a four-way pipe, the corresponding telescopic mechanisms 2 are four.
[0028] It should be noted that one end of the telescopic mechanism 2 of the present application is connected to the downpipe 6, and the other end is connected to the fixed pipe 1. The arrangement of the telescopic mechanism 2 and the fixed pipe 1 facilitates stretching during the vibration of the bridge body, thereby reducing the damage degree caused by the bridge body vibration to the downpipe 6. The adjustment mechanism 3 of the present application can adjust the stability of the telescopic mechanism 2 according to actual needs, avoiding that when the vibration amplitude of the telescopic mechanism 2 and the fixed pipe 1 is too large, it affects the tightness of the connection between the telescopic mechanism 2 and the downpipe 6, thereby improving the service life of the overall structure, reducing the maintenance frequency of the overall structure, and further reducing the maintenance cost and difficulty of the overall structure.
[0029] In the embodiment of the present application, the telescopic mechanism 2 includes a joint 21 and a connecting pipe 22. The connecting pipe 22 is connected to the corresponding pipe orifice and is configured to expand and contract along its axial direction. One end of the joint 21 is connected to the end of the connecting pipe 22 away from the pipe orifice, and the other end is connected to the corresponding downpipe 6.
[0030] In the embodiment of the present application, the connecting pipe 22 is a metal bellows.
[0031] It should be noted that the metal bellows has a certain strength while expanding and contracting, avoiding breakage under the impact of rainwater and the gravel it carries.
[0032] Furthermore, the material of the connecting pipe 22 of the present application can also be rubber, which is convenient for connecting the joint 21 and the fixed pipe 1. At the same time, when the bridge body vibrates, the connecting pipe 22 can buffer and has a certain stretchability, thereby avoiding breakage at the connection of the downpipe 6 during vibration.
[0033] In the embodiment of the present application, the adjustment mechanism 3 includes a connection component 31, a first adjustment block 33, and two second adjustment blocks 32. The two second adjustment blocks 32 are respectively rotatably arranged on the outer walls of two adjacent joints 21 and are located on the same side of the two adjacent joints 21. The first adjustment block 33 is rotatably arranged on the outer wall of the fixed pipe 1 and is located on the same side as the two second adjustment blocks 32. The first adjustment block 33 and the two second adjustment blocks 32 are both hollow structures. One end of the connection component 31 sequentially passes through one of the second adjustment blocks 32, the first adjustment block 33, and the other second adjustment block 32 and extends to the outside of the second adjustment block 32. The connection component 31 is slidably connected to the inner wall of the corresponding second adjustment block 32.
[0034] In the embodiment of the present application, the adjustment mechanism 3 further includes a plurality of fixing sleeves 34. The plurality of fixing sleeves 34 are respectively fixedly connected to the joint 21 and the connecting pipe 22. The first adjustment block 33 and the two second adjustment blocks 32 are both sleeved on the inner walls of the fixing sleeves 34 and are rotatably connected to the fixing sleeves 34.
[0035] It should be noted that annular grooves are formed on the outer walls of the first adjusting block 33 and the second adjusting block 32, and a plurality of fixing sleeves 34 are respectively installed in the corresponding annular grooves, so as to facilitate the free rotation of the first adjusting block 33 and the second adjusting block 32.
[0036] In the embodiment of the present application, the connecting component 31 includes a threaded rod and two connecting blocks 312. The two connecting blocks 312 are respectively arranged inside the corresponding second adjusting block 32, and internal threads are provided inside them. The threaded rod is provided with external threads corresponding to the internal threads. One end of the threaded rod sequentially passes through one of the second adjusting blocks 32, the first adjusting block 33 and the other second adjusting block 32, and extends to the outside of the second adjusting block 32. Both second adjusting blocks 32 are provided with sliding grooves 321, and slider assemblies 4 are arranged in the sliding grooves 321. The two connecting blocks 312 are respectively fixedly connected to the corresponding slider assemblies 4. Elastic members 5 are installed at both ends of the slider assembly 4 and on the sliding grooves 321.
[0037] It should be noted that in the present application, by adjusting the tightening degree of the threaded rod, the rigidity between the connecting pipe 22 and the fixed pipe 1 is improved, thereby reducing the deformation amplitude caused by the vibration of the bridge body, making the downspout 6 more integral, and further avoiding greater wear on the joint 21 and the downspout 6 due to excessive shaking amplitude of the connecting pipe 22 and the fixed pipe 1.
[0038] The present application reduces the wear between the threaded rod and the first adjusting block 33 and the second adjusting block 32, increases its service life, and to a certain extent reduces the impact on the downspout 6 caused by the vibration of the bridge body when the threaded rod is too tight. By compressing the elastic member 5, the threaded rod has a certain adjustment range, so as to avoid direct damage caused by excessive pressure on the downspout 6 and the threaded rod due to a sudden increase in the drainage volume.
[0039] The threaded rod located inside the first adjusting block 33 can also be two independent ones, and the thread directions of the two threaded rods are opposite, so that the two threaded rods can be driven to rotate in opposite directions, thereby making the efficiency higher and the operation simpler.
[0040] In the embodiment of the present application, the slider assembly 4 includes two sliding members 41. The two sliding members 41 are respectively fixedly connected to the top and bottom of the connecting block 312. The two elastic members 5 are respectively installed between the top of one of the sliding members 41 and the top wall of the sliding groove 321, and between the bottom of the other sliding member 41 and the bottom wall of the sliding groove 321.
[0041] In the embodiment of the present application, the connecting component 31 further includes a connecting rope 311. The threaded rod is sleeved on the outer wall of the connecting rope 311.
[0042] It should be noted that the connecting rope 311 of the present application is a steel wire rope.
[0043] In the embodiment of the present application, the fixed sleeve 34 is a bearing.
[0044] It should be noted that the outer ring of the bearing is fixed to the outer wall of the joint 21 or the fixed pipe 1, and its inner ring is fixed to the first adjustment block 33 or the second adjustment block 32.
[0045] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.
