公路桥梁伸缩缝安装方式 a、安装时，按实际温度确定其安装宽度值。
The installation way of expansion joint of highway bridge is a. When installing, the installation width is determined according to actual temperature.
b、伸缩缝安装过程，必须使用伸缩缝装置整齐排列，保持一定的倾斜度。确保伸缩装置平面与完工的桥面相平。
B, expansion joints installation process, must use expansion joints neatly arranged, to maintain a certain slope. Make sure that the expansion deck is flat with the completed bridge deck.

Highway bridge expansion joint construction method
清理槽口，使之达到设计宽度和深度，清除与位移箱埋入有干扰的钢筋，预留坑的开口必须大于伸缩缝的安装宽度。
Clear the notch so that the width and depth of the design are achieved, and the steel bars that are disturbed by the displacement box are removed. The opening of the reserved pit must be larger than the installation width of the expansion joint.
检查伸缩装置的各梁之间间隙是否符合安装温度要求，否则，应用水平千斤顶、夹具进行调整直至符合设计要求，调整好后，立即安上**夹具。
Check whether the clearance between the beams of the expansion device meets the requirements of installation temperature, otherwise, the horizontal jack and jig will be adjusted until the design requirements are met. After the adjustment, a special fixture will be installed at once.
根据伸缩缝中心位置设置起吊装置，将伸缩装置安入在槽口内，并使伸缩装置的**面与桥面标高相同。同时注意纵横坡也应与桥面相符。
A lifting device is arranged according to the center position of the expansion joint, and the telescopic device is arranged in the notch, and the top surface of the telescopic device is the same as the elevation of the bridge deck. At the same time, pay attention to the vertical and horizontal slope should be consistent with the bridge.

伸缩装置吊入预留槽后，其中心线应与梁端预留间隙中心线对正，其长度与桥梁宽度对正。
When the telescopic device is hoisted into the reserved groove, the center line of the telescopic device shall be aligned with the central clearance of the end of the beam, and the length of the line shall be opposite to the width of the bridge.
对伸缩装置直线段进行调整，并使各纵梁的缝隙均匀一致。
The straight line section of the telescopic device is adjusted, and the cracks of the longitudinal beams are uniformly uniform.
再在公路桥梁伸缩缝箱体或锚固板处，立焊Ф16以上的钢筋进行高度定位，横焊Ф16钢筋进行宽度定位。
Then the box or the anchor plate in highway bridge expansion joints, high positioning steel welding with more than 16 of the width of the transverse welding positioning with 16 steel.
伸缩装置正确就位锚固后，便可以将伸缩装置一侧的锚固钢筋和预留槽预留钢筋焊接以保证伸缩装置线向固定并找平，焊接时只要每隔2～3个锚固筋焊接一个即可，然后再按上述步骤焊接另一侧的锚固筋。待两侧达到固定后，就可将其余焊接的锚固筋再进行焊接，确保可靠锚固。在焊接锚固筋时要注意不要在边梁和中梁上任意施工焊，以防钢梁发生扭曲变形。
Telescopic device is correctly positioned after anchoring, anchoring steel telescopic device can be on one side of the slot is reserved and welded steel to ensure the expansion device to the fixed line and leveling, welding as long as every 2 ~ 3 anchoring steel welding a can, and then according to the steps of anchoring steel welding on the other side. When the two sides reach the fixed position, the other welded anchoring bars can be welded again to ensure reliable anchorage. When welding the anchor bar, be careful not to construct welding on the side beam and the middle beam in order to prevent the steel beam from twisting and deforming.

伸缩装置如果分段安装，接缝处必须焊接，焊接应由专业人员进行，每根梁焊好后，再按步骤进行锚固。
If the expansion device is installed separately, the joint must be welded. The welding shall be carried out by the professional personnel. After each beam is welded, the anchor shall be anchored according to the procedure.
根据缝的外形尺寸和预留槽口制作模板，模板放好后应遮挡严实，以防水浆流入位移箱内，伸缩缝上平面加盖板，以防砂浆落入橡胶密封带，在检查装置的正确平整度和中线位置，以及缝隙是否均符合要求后，方可灌入混凝土，并对混凝土充分振捣压实，尤其应注意位移箱与预留坑基面不能留下空洞。待混凝土固化后撤去模板和伸缩缝上的固定卡。
According to the size of the seam and reserved notch making template, template in place should cover tightly, with waterproof slurry inflow displacement box, expansion joints on the plane and cover, to prevent falling into the mortar with rubber seal, the inspection device correct flatness and the midline, and the gap are in line with the requirements, can be poured into the party concrete, and ramming compaction of concrete full vibration, especially should pay attention to the displacement and the reserved box can not leave the empty pit base. Fixed card removed template and expansion joints on the concrete to be cured.
在伸缩缝处混凝土未达到80%的强度前，公路桥梁伸缩缝不能承受外来荷载作用。
The expansion joints of highway bridges can not withstand external loads before the expansion joints reach the strength of 80%.
