[0002] Building expansion joints, also known as expansion joints, refer to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the building components due to climate and temperature changes (thermal expansion and contraction). Expansion joints divide building components above the foundation, such as walls, floor slabs, and roofs (except wooden roofs), into two independent parts, allowing the building or structure to expand and contract horizontally along the length direction. Expansion joint structures also exist in bridges.
[0003] If the plane dimension of a building is too long, excessive temperature stress may be generated in the structure due to thermal expansion and contraction. It is necessary to set a seam at a certain length of the structure to divide the building into several parts. This seam is the temperature seam.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The existing expansion joints have poor anti-clogging effects, and the debris in the expansion joints will seriously affect the service life of the bridge, because the debris will get stuck in the expansion joints, hinder the expansion and contraction of the expansion joints, causing the expansion joints to fail to work normally, seriously affecting the service life of the bridge.
[0020] In view of this, a silent expansion joint structure with anti-clogging is provided. Through the cooperation between the protrusion, the positioning plate and the connecting rod, the reserved joint position is shielded to prevent external impurities from entering and causing blockage. If blockage occurs, the provided mesh tube is also convenient for the staff to clean up later, which solves the problem that the existing expansion joint has poor anti-clogging effect. The debris in the expansion joint will seriously affect the service life of the bridge, because the debris will get stuck in the expansion joint and hinder the expansion and contraction of the expansion joint, resulting in the expansion joint being unable to work normally, seriously affecting the service life of the bridge.
[0021] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.
[0022] Embodiment 1: By Figure 1-4It can be seen that a silent expansion joint structure for preventing clogging includes a bridge body 1, a poured concrete layer 2 is arranged on the inner side of the bridge body 1, anchor bars 4 and embedded bars 3 are arranged inside the poured concrete layer 2, a reserved seam 13 is processed on the inner side of the bridge body 1, and the reserved seam 13 is an expansion joint, a side beam 5 is arranged on the inner side of the poured concrete layer 2, and a protective mechanism is arranged inside the bridge body 1, and the protective mechanism includes a rubber sheet 6, a convex block 7, a connecting rod 9, a positioning plate 8, a round rod 17 and a mesh tube 18, and the outer wall of the rubber sheet 6 is divided into two sides. The rubber sheet 6 is movably connected to the grooves on both sides of the top of the side beam 5, and the top groove of the rubber sheet 6 is movably connected to a convex block 7 fixed on the inner side of the groove of the side beam 5. The convex block 7 is snap-fitted with the top groove of the rubber sheet 6 for positioning. The rubber sheet 6 and the connecting rod 9 are fixed with glue. The bottom of the rubber sheet 6 is fixed with a positioning plate 8 through the connecting rod 9. The inner cavity of the positioning plate 8 is movably connected with a round rod 17, and the round rod 17 can move in the cavity of the positioning plate 8. A net tube 18 is fixed to the lower part of the outer wall of the round rod 17;
[0023] In the specific implementation process, it is worth pointing out that the reserved joint position is shielded by the cooperation between the positioning plate 8, the round rod 17 and the mesh tube 18 to prevent the entry of foreign impurities and cause clogging. If clogging occurs, the set mesh tube 18 is also convenient for the staff to clean up later, which solves the problem that the existing expansion joint has poor anti-clogging effect, and the debris in the expansion joint will seriously affect the service life of the bridge, because the debris will get stuck in the expansion joint, hinder the expansion and contraction of the expansion joint, resulting in the expansion joint being unable to work normally, seriously affecting the service life of the bridge;
[0024] Further, the outer side of the positioning plate 8 is movably connected with a straight plate 10, and the positioning plate 8 and the straight plate 10 are fixed with screws. After being fixed, the two move synchronously, wherein the positioning plate 8 can only be taken out upward, and the size of the net tube 18 is smaller than the through hole of the straight plate 10, which can ensure the normal passage of the net tube 18, and the outer side of the straight plate 10 is movably connected with the inner side of the reserved seam 13 and the inner groove of the side beam 5, and the straight plate 10 can move in the inner side of the reserved seam 13 and the inner groove of the side beam 5, and the through hole of the straight plate 10 is movably connected with a slide bar 11, and the outer side of the slide bar 11 is movably connected with a spring 12, and the device can buffer the pressure on the rubber sheet 6 by the elastic deformation of the spring 12 to reduce noise, and the two ends of the spring 12 are respectively fixedly connected to the bottom of the straight plate 10 and the bottom of the inner groove of the side beam 5;
[0025] In the specific implementation process, it is worth pointing out that after the external vehicle contacts the rubber sheet 6, it will move downward, thereby driving the connecting rod 9 to indirectly compress the spring 12. The elastic deformation of the spring 12 can buffer the pressure on the rubber sheet 6 and reduce noise. Since the round rod 17 can move in the cavity of the positioning plate 8, it will not affect the downward movement of the straight plate 10 to compress the spring 12. There are multiple groups of structures such as the straight plate 10 and the positioning plate 8. The number of settings is not limited, and it is best to be evenly arranged below the rubber sheet 6;
[0026] Furthermore, the outer side of the net tube 18 is movably connected to a limit plate 19, and there are two limit plates 19. Rubber strips are installed on the inner sides of the two limit plates 19. The rubber strips do not affect the deformation of the reserved seam 13. The outer side of the limit plate 19 is fixedly connected to the inner side of the side beam 5. Two bent plates 20 are fixedly connected to the bottom of the limit plate 19. The inner lower sides of the two bent plates 20 are in contact with the bottom of the net tube 18.
[0027] In the specific implementation process, it is worth pointing out that the two bent plates 20 can limit the bottom of the net cylinder 18, and the limiting plate 19 can limit the net cylinder 18;
[0028] Specifically, when using the anti-clogging silent expansion joint structure, an external vehicle will move downward after contacting the rubber sheet 6, thereby driving the connecting rod 9 to indirectly compress the spring 12. The elastic deformation of the spring 12 can buffer the pressure on the rubber sheet 6 and reduce noise. When the rubber sheet 6 is damaged, impurities will be contained by the mesh tube 18 below. When cleaning is required, the user can remove the bolts between the positioning plate 8 and the straight plate 10, and then lift the positioning plate 8 upwards. At the same time, the mesh tube 18 is lifted, and the staff can centrally dispose of the garbage in the mesh tube 18.
[0029] Embodiment 2: By Figure 1-2 It can be seen that two blocks 14 are installed on both sides of the inner wall of the reserved gap 13, and the inner sides of the two blocks 14 are movably connected to the sealing strip 15;
[0030] In the specific implementation process, it is worth pointing out that the two sealing strips 15 ensure the sealing effect below the reserved seam 13;
[0031] Furthermore, the interior of the two sealing strips 15 is filled with a moisture absorbing agent bag 16;
[0032] In the specific implementation process, it is worth pointing out that the moisture absorbent bag 16 can absorb water vapor to prevent the sealing effect of the bottom of the device from being affected after the lower sealing strip 15 is damaged;
[0033] Specifically, based on the above-mentioned embodiment 1, the sealing strip 15, the desiccant bag 16 and the block 14 are used to seal the position below the reserved seam 13, thereby preventing water vapor from entering the gap from below and affecting the service life of the spring 12 and other structures, thereby reducing the cost of use.
