GQF-E80型橋梁伸縮縫的現(xiàn)場安裝
將兩段伸縮縫裝置上平面置于同一水平面上，使兩段伸縮裝置接口處緊密靠攏，并校直找正。(2)用鋼絲刷清除浮銹，用石棉繩填塞到對(duì)接處的凹槽內(nèi)，以防焊渣流入。(3)用的506焊條逐步焊接。(4)刷防銹漆。伸縮裝置的吊裝就位吊裝時(shí)應(yīng)按照廠方表明的吊點(diǎn)位置起吊。安裝時(shí)，伸縮裝置的中心線應(yīng)與梁端預(yù)智槽伸縮縫預(yù)留間隙中心線想重合（可用吊繩法找平），其長度與橋?qū)挾葘?duì)應(yīng)，然后穿放橫向聯(lián)結(jié)水平鋼筋，并將邊梁墊起（不可懸空）。GQF-E80型橋梁伸縮縫的標(biāo)高與固定,沿橋?qū)挋M向每隔1.2m放置一橫吊梁。使伸縮裝置上頂面緊密貼在槽鋼下面，以兩側(cè)瀝青混凝土面層的標(biāo)高為準(zhǔn)，控制伸縮縫的標(biāo)高，然后對(duì)伸縮縫的縱向直線度也進(jìn)行調(diào)整。伸縮縫的標(biāo)高直線度調(diào)整到符合設(shè)計(jì)要求后，可進(jìn)行臨時(shí)固定，固定時(shí)應(yīng)沿橋?qū)挼囊欢讼蛄硪欢艘来螌⑸炜s縫邊梁上的錨固裝置與預(yù)留槽的預(yù)埋鋼筋每隔2-3個(gè)錨固筋骨焊一個(gè)焊點(diǎn)，兩側(cè)對(duì)稱施焊，以抄平后的伸縮縫不再發(fā)生變位，嚴(yán)禁從一端平移施焊，造成伸縮縫翹曲。

衡水路翔公司為您提供Z型橋梁伸縮縫產(chǎn)品在橋梁上安裝時(shí)的步驟及注意事項(xiàng)：
Steps and precautions for installing Z-bridge expansion joint products on bridges:
1、當(dāng)工程施工單位在安裝橋梁伸縮縫時(shí)，一旦發(fā)生碰撞變形，很難修復(fù)為合格產(chǎn)品，
When the construction unit is installing the bridge expansion joint, once the collision deformation occurs, it is difficult to repair it as a qualified product.
所以在安裝的全過程中，一定要采取措施保護(hù)，嚴(yán)禁任何車輛通過。
Therefore, in the whole process of installation, measures must be taken to protect and prohibit any vehicles from passing.
2、一定要精心操作。如果出現(xiàn)現(xiàn)場不易調(diào)整，所以對(duì)伸縮縫的成品檢查一定要認(rèn)真、仔細(xì)。不合格不可運(yùn)至現(xiàn)場。
Be careful. If the scene is difficult to adjust, the inspection of the finished product of the expansion joint must be careful and careful. Failure to pass shall not be shipped to the site.
3、在橋梁伸縮縫在安裝前，要與設(shè)計(jì)圖和現(xiàn)場核對(duì)位置、尺寸無誤后，再穩(wěn)放入預(yù)留槽。
Before the bridge expansion joint is installed, it must be placed in the reserved slot after the design and the site check position and size are correct.
要將橋上各接縫處縫隙一定要用聚苯乙烯泡沫板塞嚴(yán)，防止?jié)沧⒈Ｗo(hù)帶混凝土?xí)r灌入，使縫失效。
The gap between the joints on the bridge must be tightly packed with polystyrene foam board to prevent the pouring of the concrete when pouring the protective belt, and the joint is invalidated.
同時(shí)，也不可將裝置內(nèi)灌進(jìn)混凝土，以免更換V形象膠帶時(shí)受阻。
At the same time, it is not possible to pour the device into the concrete to avoid being blocked when replacing the V-image tape.
4.、在保護(hù)帶混凝土澆筑后，前7-8日一定要及時(shí)灑水養(yǎng)護(hù)，以利強(qiáng)度增長和防止裂縫出現(xiàn)。
After the concrete is poured in the protective belt, the first 7-8 days must be sprinkled and maintained in time to increase the strength and prevent cracks.
