工安装前应按照设计图纸提供的尺寸,核对梁、板端部及桥台处安装公路桥梁伸缩缝装置的预留槽的尺寸。若图纸上未注明,则模数式伸缩装置,伸缩量为160mm时,预留槽深度应大于或等于250mm,其余伸缩量应根据需要逐级加深。异型钢单缝式伸缩装置的预留槽深度应大于或等于150mm。同时应检查核对预埋锚固钢筋的规格、数量、位置与设计的一致性,与梁、板、桥台锚固的可靠性;检查核对梁、板与桥台间的伸缩缝与设计值是否一致,若不符合设计要求,施工单位应首先处理,满足设计要求后生产厂方可安装伸缩装置。
The size of the reserved slot for the installation of the expansion joint of the road bridge shall be checked according to the size provided by the design drawings in the end of the installation. If the drawing does not specify, then the modulus expansion device, the amount of expansion is 160mm, the reserve groove depth should be greater than or equal to 250mm, and the remaining expansion amount should be gradually deepened according to needs. The depth of the reserved groove of the special-shaped steel single slit telescopic device shall be greater than or equal to 150mm. At the same time should check the consistency of the location and design specifications, quantity, pre embedded anchor bar, beam, plate, and the reliability of abutment anchorage; check telescopic beam, plate and the gap between the abutment is consistent with the design value, if it does not comply with the design requirements, the construction unit should first meet the design requirements after the treatment. The production of the expansion device can be installed.
伸缩装置上桥安装之前,应按照安装时气温调整安装时的定位值,并应由安装负责人检查签字后方可用专用卡具将其固定。伸缩装置吊装就位前,应将预留槽内混凝土打毛并清扫干净。吊装时应按照工厂标明的吊点位置起吊,必要时可作适当加强。
Before the installation of bridge expansion device, should be in accordance with the installation location and installation of the temperature adjustment value, and shall be responsible for the installation check signed available special fixture will be fixed. Before the expansion device is hoisted, the concrete in the reserved tank should be cleaned and cleaned. When lifting, it should be hoisted according to the hanging point indicated by the factory, and can be properly strengthened if necessary.

安装时,伸缩装置的中心线应与桥梁中心线相重合,伸缩装置顺桥向应对称放置于伸缩缝的间隙上,然后沿桥面横坡方向,每米一点测量水平标高,并用水平尺或板尺定位,使其顶面标高与设计要求相吻合后垫平。随即穿放横向联接水平钢筋,并将伸缩装置的锚固钢筋与梁、板或桥台上预埋钢筋两侧同时焊牢。如有困难,可先将一侧焊牢,待达到已确定的安装气温时,再将另一侧锚固钢筋全部焊牢,放松卡具,使其自由伸缩。
When installed, the center line of the expansion device should coincide with the center line of the bridge expansion device, placed along the bridge clearance from the joints to be symmetrical, and then along the deck transverse slope direction, a horizontal elevation measurement per meter, and with horizontal feet or board foot position, the top surface elevation and design requirements anastomosis pad. Then wear a cross connection level and reinforcement, anchoring steel telescopic device and beam, plate or abutment pre buried steel welded on both sides at the same time. If there is difficulty, the first side welding, installation to temperature has been determined, and then the other side anchor bars all welded, relaxed fixtures, the free expansion.
梳齿板式伸缩装置安装,应防止产生梳齿不平、扭曲及其他的变形,严格控制由于伸缩方向的误差及横向伸缩等原因造成梳齿之间的间隙偏差,在最高温度时,梳齿间横向间隙不应小于5mm,齿板间隙不应小于15mm。
Comb type retractor device installation should prevent deformation, distortion and other uneven comb, strictly control the error due to telescopic direction and transverse expansion caused by the gap between teeth, at the highest temperature, the transverse distance between comb teeth should not be less than 5mm, tooth plate gap should not be less than 15mm.
公路桥梁伸缩缝安装装置,安装后应处于受压状态。浇注混凝土前,应彻底清扫预留槽,并在伸缩缝间隙处用泡沫塑料将间隙填塞,然后安装必要的模板。混凝土预留槽内应浇注C40环氧树脂混凝土或C50钢纤维混凝土,也可用C50以上强度等级的混凝土填充捣实。应防止混凝土渗入模数式伸缩装置位移控制箱内,也不允许将混凝土溅填在密封橡胶带缝中及表面上。如果发生此现象,应予以清除,然后进行正常养护。伸缩装置两侧预留槽混凝土强度在未满足设计要求前不得开放交通。伸缩装置施工验收应按照JTJ071的规定进行。

The installation device for expansion joints of highway bridges shall be in a compression state after installation. Before placing the concrete, the reserve tank shall be thoroughly cleaned and the gap shall be filled with foam plastic in the gap of the expansion joint, and then the necessary formwork shall be installed. The concrete reserved trough shall be C40 epoxy resin concrete or C50 steel fiber concrete, and the concrete filled with C50 or more strength grade shall be filled and tamped. Concrete shall be prevented from penetrating into the displacement control box of the modular expansion device, and concrete shall not be allowed to be splashed on the surface and surface of the sealing rubber band. If this occurs, it should be removed and then properly maintained. The concrete strength of the reserved slot on both sides of the expansion device shall not be open until the design requirements have been met. The construction and acceptance of the telescopic device shall be carried out in accordance with the provisions of JTJ071.
