施工注意事項(xiàng):保持墩臺(tái)墊石頂面清潔。如果支承墊石標(biāo)高差距超過(guò)標(biāo)準(zhǔn)要求,必須用水泥砂漿進(jìn)行標(biāo)高調(diào)整。在支承墊石上按設(shè)計(jì)圖標(biāo)出中心,安裝時(shí)橡膠支座的中心與支承墊石中心線要吻合,以確保支座就位準(zhǔn)確。在澆注梁體前,在支座上放置一塊比支座平面稍大的支承鋼 板,鋼板上焊接錨固鋼筋與梁體連接,并把支承鋼板視作澆梁模板的 一部分進(jìn)行澆注,按以上方法進(jìn)行,可以使支座與梁底鋼板及墊石頂面全部密貼。預(yù)制梁橡膠支座的安裝:安裝好預(yù)制梁橡膠支座的關(guān)鍵在于保證梁底在墊石頂面的平行、平整,使其和支座上、下表面全部密貼,不得出現(xiàn)偏壓、脫空和不均勻支承受力現(xiàn)象。施工程序如下:處理好支撐墊石,使支撐墊石標(biāo)高一致。預(yù)制梁與支座接觸的底面要保持水平和平整。當(dāng)有蜂窩漿和傾斜度時(shí),要預(yù)先用水泥砂漿搗實(shí)、整平。
Note: keep the construction of pier pad stone tops clean. If the gap between supports and stones exceeds the standard requirements, the cement mortar shall be used for elevation adjustment. On the support pad stone, the center shall be designed according to the design icon, and the center of the rubber bearing shall be in conformity with the center line of the support pad when installing, so as to ensure that the bearing is in correct position. In the pouring of beam before placing a slightly larger than the bearing plane of the bearing plate on the support plate, welded anchor bar and beam body connection, and part of the supporting steel plate girder as a template for casting, according to the above method, can make the bearing beam and the bottom steel plate and pad stone tops all. Stick. Prefabricated bridge rubber bearing installation: key pre installed bridge rubber bearing pad stone is to ensure that the top surface of the beam bottom in parallel and smooth, and the support of the upper and lower surfaces all close, there shall be no bias, void and uneven supporting force. Construction procedures are as follows: handle support stone, so that the support pad stone elevation. The bottom surface of the precast beam and the support shall be kept level and smooth. When there is a slurry and tilt, it should be pre - compacted with cement mortar, leveling.
橡膠支座的正確就位先使支座和支承墊石按設(shè)計(jì)要求準(zhǔn)確就位。架梁落梁時(shí),T型梁的縱軸線要與支座中心線重合;板梁、箱梁的縱軸線與支座中心線相平行。為落梁準(zhǔn)確,在架第一跨板梁或箱梁時(shí),可在梁底劃好二個(gè)支座的十字位置中心,在梁的端立面上標(biāo)出兩個(gè)支座的位置中心線的鉛直線,落梁時(shí)使之與墩臺(tái)上的位置中心線相重合。以后數(shù)跨可依照第一跨梁為基準(zhǔn)進(jìn)行。在架梁落梁時(shí)要平穩(wěn),防止壓偏或產(chǎn)生初始剪切變形,大家可以參考鐵路橋梁板式橡膠支座規(guī)格表 。在安裝 T型橋梁時(shí),若橡膠支座比梁筋底寬,則應(yīng)在支座與梁筋底之間加設(shè)比支座大的鋼筋混凝土墊塊或厚鋼板做過(guò)渡層,以免支座局 部受壓,而形成應(yīng)力集中。鋼筋砼墊塊或厚鋼板要用環(huán)氧樹(shù)脂砂漿和梁筋底貼合粘結(jié)。落梁后,一般情況下橡膠支座頂面與梁面保持水平。預(yù)應(yīng)力簡(jiǎn)支梁,其支座頂面可稍后傾;非預(yù)應(yīng)力梁其支座頂面可略微前傾,但傾斜角度不得超過(guò)5"。
The correct position of the rubber bearing first makes the bearing and the supporting stone accurately positioned according to the design requirements. When the frame beam falls, the longitudinal axis of the T beam should coincide with the central line of the bearing; the longitudinal axis of the plate beam and the box girder are parallel to the center line of the support. For the first frame in the fall beam accurately, cross slab beam or box girder, cross the center position can be marked two supports at the end of the beam, the lead line and mark the position the center line of two bearings in the end elevation on the beam, beam falling when the phase coincides with the position of the center line on the pier. The subsequent spans may be carried out on the basis of the first cross beam. When the frame beam is falling, it is necessary to be stable, to prevent partial deflection or initial shear deformation. The installation of T type bridge, if the rubber bearing ratio of beam bar bottom width should be in between the bearing and the bottom beam reinforcement added support than reinforced concrete pad or thick plate transition layer, to support local compression, and the formation of stress concentration. Reinforced concrete block or thick steel plate should be bonded with epoxy resin mortar and beam reinforcement. After falling beam, generally, the top surface of rubber bearing is kept level with the beam. Prestressed simply supported beam, its bearing top surface may later incline; non - prestressed beam, its bearing top surface may slightly forward, but the angle of inclination may not exceed 5".
