[0022] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Specific embodiment 1:

[0024] Refer to Figures 1-5, a plate - type bridge expansion joint device, comprising a beam body 1. A water - stop belt 4 is arranged in the middle of two beam bodies 1.

One end of each of the eight screws 11 penetrates into the inside of the beam body 1, and the other end of the screw 11 penetrates through the water - stop belt 4, the framework 12, and the plate - type rubber expansion joint 2. The eight screws 11 are evenly set in groups of two at the edges of the two ends of the two plate - type rubber expansion joints 2. The eight fixing pieces 13 are all installed on the screws 11, and the plate - type rubber expansion joint 2 is fixed on the top surface of the framework 12 through the fixing piece 13. The two slots 15 are set at the two ends of the top surface of the plate - type rubber expansion joint 2, and the slot 15 is set in the middle of the screw 11. The two sleeves 8 are both fixed in the slots 15 of the plate - type rubber expansion joint 2 through the fixed bolts 16. The areas of the two buffer plates 9 are the same as the areas of the two plate - type rubber expansion joints 2. The positions where the four sleeve rods 10 are set are the same as the positions where the sleeves 8 are set, and the sleeve rods 10 are all installed in the sleeves 8. The two clamping blocks 6 are both set on the sides of the two upper rubber plates 5, and the two upper rubber plates 5 are connected together through the clamping blocks 6. Fixed bolts 16 are arranged on the tops of the two upper rubber plates 5 and the side rubber plates 3, and the upper rubber plates 5 and the side rubber plates 3 are both fixed on the top surfaces of the two beam bodies 1 through the fixed bolts 16.

[0025] The edges of the two beam bodies 1 that are close to each other laterally are provided with preset grooves, and the sizes of the preset grooves are the same. The two ends of the waterstop 4 are respectively installed in the preset grooves on the top surfaces of the two beam bodies 1. The waterstop 4 is made of rubber material. The waterstop 4 automatically expands and contracts with the deformation of the expansion joint, which can effectively prevent water from leaking from the expansion joint, thereby ensuring the dryness and water tightness of the building. A frame 12 is installed on the top surface of the waterstop 4. The frame 12 provides a place for installing the plate rubber expansion joint 2. The position where the frame 12 is established is consistent with the position where the two preset grooves are established, and the two ends of the bottom surfaces of the two plate rubber expansion joints 2 are installed on the top surface of the frame 12. Four screws 11 are provided at the bottom of the two plate rubber expansion joints 2, and one end of the eight screws 11 penetrates into the interior of the beam body 1, and The other end of the screw rod 11 passes through the water stop 4, the frame 12 and the plate rubber expansion joint 2. Eight screw rods 11 are evenly set up at the left and right edges of the two plate rubber expansion joints 2 in groups of two. Eight fixing members 13 are all installed on the screw rods 11. The fixing members 13 are set up at the top of the plate rubber expansion joint 2. Through the cooperation of the screw rods 11 and the fixing members 13, the plate rubber expansion joint 2, the frame 12 and the water stop 4 are fixed to the top of the beam body 1. Two slots 15 are provided at the left and right ends of the top surface of the plate rubber expansion joint 2. Two sleeves 8 are set up in the middle of the slots 15 on the top surface of the plate rubber expansion joint 2 and are fixed in the slots 15 of the plate rubber expansion joint 2 by two fixing bolts 16. Buffer springs 14 are provided inside the sleeves 8. The sleeve 8 will prevent the buffer spring 14 from tilting around when it is stressed. The two sleeve rods 10 on the bottom of the buffer plate 9 are installed in the sleeve 8. In this way, when there is an impact force from above, the buffer plate 9 is forced to move downward. When the buffer plate 9 moves downward, the sleeve rod 10 on the bottom of the buffer plate 9 will move downward in the sleeve 8. Since the buffer spring 14 is arranged inside the sleeve 8, when the buffer spring 14 receives the pressure of the sleeve rod 10, the buffer spring 14 is deformed under stress and the kinetic energy of the external force is converted into elastic energy storage. This energy conversion makes the compression or stretching of the external force on the buffer spring 14 more uniform, and stores the kinetic energy in the buffer spring 14. When the external force ends, the elastic energy stored in the buffer spring 14 is released, and the buffer spring 14 The buffer plate 9 is provided with a buffer pad 7 on top. When pressure is transmitted from above, the elastic material itself is used to reduce the impact force generated during the collision. An upper rubber plate 5 is provided on top of the buffer pad 7. The upper rubber plate 5 is fixed to the top surface of the beam body 1 by four fixing bolts 16. The four fixing bolts 16 are evenly arranged on the edges of the left and right ends of the upper rubber plate 5. In this way, in daily use, since the top of the plate-type rubber expansion joint 2 is provided with a buffer plate 9, a buffer pad 7 and an upper rubber plate 5, the buffer plate 9, the buffer pad 7 and the upper rubber plate 5 will block the direct contact between sunlight and rain and the plate-type rubber expansion joint 2, and prevent dust from entering the slot 15 on the top surface of the plate-type rubber expansion joint 2.On the upper rubber plate 5, the side rubber plates 3 on both sides are fixed to the beam body 1 by fixing bolts 16. When installing the upper rubber plate 5, positioning and fixing can be carried out through the clamping blocks 6 on the left and right sides of the upper rubber plate 5, preventing the two upper rubber plates 5 from shifting during installation. Since the side rubber plates 3 are inclined and the highest end of the side rubber plate 3 is flush with the top surface of the upper rubber plate 5, the vehicle can drive onto the upper rubber plate 5 through the side rubber plate 3, preventing the vehicle from jumping and generating noise when driving over the upper rubber plate 5.

[0026] When the building is subjected to external forces, such as thermal expansion and contraction caused by temperature changes, the rubber body of the plate rubber expansion joint 2 will undergo shear deformation and absorb this deformation energy. This shear deformation can effectively reduce the stress generated in the building when subjected to external forces, avoiding structural damage caused by stress concentration. Specific Embodiment 2:

[0028] Refer to Figures 1-5 , a plate - type bridge expansion joint device. Further based on the basic structure in Specific Embodiment 1, an adhesive can be poured between the connection points of the clamping blocks 6 of the two upper rubber plates 5 and the connection points between the two side rubber plates 3 and the upper rubber plates 5, and an adhesive can also be poured at the place where the fixing bolts 16 are installed. In this way, the two side rubber plates 3 and the two upper rubber plates 5 form a sealed whole, effectively preventing water from entering the buffer pad 7, buffer plate 9, and plate rubber expansion joint 2 from the connection points between the two upper rubber plates 5 and the two side rubber plates 3 and the installation place of the fixing bolts 16.

[0029] In summary:

[0030] 1. Two sleeves 8 are set in the slot holes 15 on the top surface of the plate rubber expansion joint 2. Two sleeve rods 10 at the bottom of the buffer plate 9 are installed in the sleeves 8. A buffer pad 7 is provided at the top of the buffer plate 9, and an upper rubber plate 5 is provided at the top of the buffer pad 7. The upper rubber plate 5 is fixed to the top surface of the beam body 1 by four fixing bolts 16. In daily use, since the buffer plate 9, buffer pad 7, and upper rubber plate 5 are provided on the top of the plate rubber expansion joint 2, the buffer plate 9, buffer pad 7, and upper rubber plate 5 will block the direct contact of sunlight and rainwater with the plate rubber expansion joint 2 and prevent dust from entering the slot holes 15 on the top surface of the plate rubber expansion joint 2, solving the disadvantages that the rubber plate body is easily aged when exposed, resulting in performance degradation, and dust will fall into the gaps of the rubber plate body, thus affecting the elasticity of the rubber body.
