In order to meet the requirements of bridge deck deformation, bridge expansion joints are usually set up between the two beam ends, between the beam ends and the bridge abutment, or at the hinged position of the bridge. .
< Types and models of bridge expansion joints:
< , galvanized thin steel plate expansion joints. This is a simple expansion joint. Currently, it is often used on prefabricated simply supported girder bridges with small and medium spans when the deformation of the beam is within a certain range.
< , steel expansion joints. Steel expansion joints are made of steel. They can directly bear vehicle loads, and the thickness of the steel cover plate can be adjusted according to the amount of expansion. Steel expansion joints are also suitable for trial use on inclined bridges. Its structure is relatively complex and is only used in areas with large temperature differences or on bridges with large spans. When the span is very large, on the one hand, the steel plate needs to be thickened, and on the other hand, a more complete comb-shaped steel plate expansion joint needs to be used.
< , rubber expansion joints. It uses rubber straps as the cross-seam material. This kind of expansion joint has a simple structure, is easy to use and has good effect. On long-span bridges with large deformations, expansion joints combining rubber and steel plates can be used.

< < (3) Design and manufacturing technical conditions:
< , Design load: Designed using the vehicle&& super load specified in the "Highway Engineering Technical Standards".
< . The special-shaped steel material used in this structure is special steel for bridges. The tensile strength of the steel should not be less than that of the allowable bending stress.
< , The supporting beams in the structure are made of steel, and the allowable bending stress is not less than.
< . Steel materials of no less than strength can be used for other accessories.
< < (4) Structural features:
< The outstanding feature of the & type telescopic device is that the load-bearing structure and the displacement control system of the telescopic device are separated. The two do not interfere with each other when they are stressed, and the division of labor is clear. This not only ensures safety when the force is applied, but also ensures uniform displacement when the force is applied.
< < (5) Determination of the expansion amount of the telescopic device:
< The calculated value of the expansion amount of the bridge directly affects the selection of the specifications of the telescopic device. If the specification selection of the telescopic device is unreasonable, it will directly affect the use of the telescopic device. At the same time, when selecting the telescopic device, the gap between the telescopic device between the beam and the plate should also be considered to ensure that the telescopic device is fully anchored to both ends of the beam and plate to achieve the best use effect. Therefore, when selecting the specifications of the telescopic device, you must leave enough excess to ensure the effectiveness and durability of the telescopic device.
< < (6) After the bridge design unit selects our company's telescopic device, in order to facilitate processing and production, the following information should be provided:
< , Cross-sectional view of the bridge (including cross-slope, sidewalk , seat belts, railings, location and size).
< , the construction implementation time of the telescopic device and the temperature change range during installation.
< If users have special requirements, they should be clearly stated.
< Note: If the user does not provide a positioning value, the factory will compress the product by half of its rated maximum expansion and contraction before leaving the factory.
< < (7) Transportation, storage and installation of the telescopic device:
< Transportation:
< After the telescopic device is fully assembled according to the design requirements, it will be transported to the construction site by the manufacturer or user. If the length exceeds the allowable limit for transportation or cannot be transported as a whole due to other reasons, the segmented production method can be used.
< Storage:
< After the telescopic device arrives at the construction site, its storage location should be as close as possible to the installation location, and should be placed on a support at least c higher than the ground.
< Installation:
< For the same excellent telescopic device, different installation quality will have obvious differences in usage effect and durability. This problem reflected in our research fully illustrates that the construction and installation quality of the telescopic device is the last key link to ensure the effectiveness of the telescopic device.
< . The installation of the telescopic device should be carried out after the road is paved as much as possible. Before the installation of the telescopic device, the width, depth and embedded steel bars of the reserved groove must be checked to ensure that they meet the requirements for installing the telescopic device. .
< When cleaning the slot, all dirt, dust and other unnecessary things must be removed.
< . Check whether the gap between the beams of the telescopic device meets the installation temperature requirements. If it does not meet the requirements, it must be adjusted under the guidance of the engineering and technical personnel of the manufacturer to make the gap between the beams of the telescopic device meet the design requirements. After adjustment, install the clamp in preparation for installation.
< , Take the asphalt pavement on both sides as the elevation, use lifting equipment to place the telescopic device in the slot, adjust the telescopic device so that the top surface is the same as the road surface elevation, and its longitudinal and transverse slopes should be consistent with the bridge road surface .
< . Check the position of the telescopic device to ensure that the position of the telescopic device in the direction of the vertical joint and along the joint direction meets the design requirements. If individual embedded steel bars hinder the correct installation of the telescopic device at this time, gas cutting can be used Cut off.
< After the telescopic device is correctly in place, first connect and weld the anchor bars on one side of the telescopic device to the embedded steel bars in the reserved slots. During welding, you can weld one at a time, and then connect the anchor bars on the other side. The steel bars are welded according to the above steps. When the telescopic device is confirmed to be fixed, the clamp can be removed, and then the remaining unwelded anchoring steel bars and the embedded steel bars are completely welded to ensure that the telescopic device is reliably anchored. Note: It is strictly prohibited to perform any welding on the center beam and side beam of the telescopic device.
< If the telescopic device is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing factory, and can be installed after the two adjacent seams are aligned. After each beam is welded, anchor it according to the above steps.
< . Install the formwork on the beam end. The formwork should be made according to the external dimensions of the telescopic device and the gap of the reserved slot. The formwork should be made very tight to prevent mortar from flowing into the displacement control box or into the gap at the beam end.
< After checking that the installed formwork is tight and seamless, clean the reserved groove, then pour concrete and vibrate it tightly. The concrete must be at least as strong as the structural concrete at that location, and the top surface of the telescopic unit must be kept clean while the concrete is being poured.
