天津安裝橋梁伸縮縫前要按照設計核對預留槽尺寸 2024-07-13

安裝橋梁伸縮縫前要按照設計核對預留槽尺寸,并將預留槽內清掃干凈。要對需切割的橋面部分彈白色油漆線,以保證開槽縫的整齊、順直,對于橋面系統伸縮位置兩側路面變形部分,要適當加寬切除寬度,以保證混凝土與瀝青混凝土接頭部分平整,另外,在切割時注意對路面的保護,做到不污染、不破壞為止。橋梁伸縮縫GQF-F在變形量較大的大跨度橋上,可以采用橡膠和鋼板組合的橋梁伸縮縫。查看反省邊梁與橋面鋪裝銜接處能否有損壞、裂痕呈現,形成滲漏現象,一經發現應實時修補,以免影響伸縮安裝與梁、板間錨固強度。查看伸縮安裝頂面能否平坦,如呈現異常不服景......

天津橋梁伸縮縫是橋梁上必不可少的一個小構造 2024-07-06

橋梁伸縮縫是橋梁上必不可少的一個小構造,橋梁伸縮縫指的是為滿足橋面變形的要求,在兩梁端之間、梁端與橋臺之間或橋梁的鉸接位置上而設置的一個小構造,要求在平行、垂直于橋梁軸線的兩個方向,均能自由伸縮。在動荷、溫度、混凝土的收縮和徐變作用下,梁體產生位移,位移過大時就會影響行車舒適和安全,為了調節由車輛荷載和橋梁建筑材料所引起的上部結構之間的位移和聯結而設置伸縮縫。橋梁伸縮縫有哪些類型,都有什么特點?橋梁伸縮縫類型:1、無縫式:暗縫型(橋面連續、TST);2、對接式:填塞對接式、嵌固對接式(仿毛勒式);3、鋼制支承式(梳......

天津橋梁裂縫產生的原因?橋梁伸縮縫來獨擋一面! 2024-07-06

由于混凝土裂縫而影響工程質量甚至造成橋梁直接倒塌的案例也不少見,因此作為工程技術人員對裂縫引起足夠的重視。橋梁裂縫產生的原因從客觀因素來講氣溫條件例如:現場施工氣溫高,時達40℃以上,風速大濕度低,加上高標號混凝土產生的大量水化熱以及烈日暴曬,致使梁體的內外溫差遠遠超過25℃從主觀方面來講:施工工藝差異及混凝土材性:例如混凝土的初凝時間僅為3小時,遠小于澆筑時間,上層混凝土在澆筑的過程中,下層混凝土已經初凝,在荷載的作用下就會出現裂縫。橋梁裂縫產生如何處理放線過程中找出梁端間隙的中心線,按照設計的位置及尺寸準確畫線......

天津橋梁伸縮縫在焊接的時候要注意哪些呢? 2024-06-29

橋梁伸縮縫在焊接的同時,應隨時用三米直尺、塞尺檢測異型鋼的平整度,平整度應控制在0-2mm范圍,否則很容易出現跳車現象。在固定焊接時,對經常出現的預留槽內預埋筋與異型鋼梁錨固筋不相符現象,要采用U型、L型、S型鋼筋進行加固連接,以確保縫體與梁體的牢固連接。就是用鉤機把混凝土打開,要不伸縮縫及其錨固筋都得從混凝土摳出來,之后就可以進行重新設置槽的寬度跟深度,之后就跟次安裝伸縮縫一樣了。伸縮縫的標高控制與固定采用龍門吊架和10x10角鋼作定位角鋼,使伸縮縫上頂面比兩側瀝青砼面層的標高低約2~3mm,控制伸縮縫的標高,然......

天津橋梁伸縮縫切縫在施工前依據施工規劃圖紙放樣 2024-06-29

橋梁伸縮縫切縫在施工前依據施工規劃圖紙放樣,運用切割機據縫,留意對據縫線以外路面的維護,避免污染,并確保切縫切斷無缺。開槽用風鎬開槽,應將槽內混凝土及雜物鏟除潔凈,尤其是梁端空隙內的雜物,并理順、調直槽內預埋筋,如發現預埋筋數量缺乏,應打膨脹螺栓,補足預埋鋼筋,并請業主代表、監理人員一起檢驗、確保彈性縫的質量。當橋梁受車輛荷載、橋梁建筑材料的物理性能等條件影響時,橋梁伸縮縫可以調節橋梁上部結構位移和上部結構之間的連接問題。橋梁伸縮縫裝置是橋梁構造中的一個重要部分,所以橋梁伸縮縫的設計和安裝都要非常重要,如果橋梁伸縮......

天津GQF橋梁伸縮縫-F60型特點及適用范圍有哪些? 2024-06-22

GQF橋梁伸縮縫-F60型特點:GQF-F型橋梁伸縮縫是由兩條F型鋼組成,中縫由橡膠止水條止水。橋面鋪裝層厚度≥80mm、伸縮量≤80mm的橋梁均可選用。    GQF-F型橋梁伸縮縫采用整體熱軋16Mn異型鋼,克服了擠壓異型鋼直線度和集合尺寸不均勻的特點, 建筑高度低,國產熱軋整體成型異型鋼材高度僅50mm,結構簡單,安裝方便,具有明顯的可靠性、舒適性和耐久性。既方便舊伸縮裝置更換,又可供新橋時選用。    技術要求:1. 橡膠采用氯丁橡膠(即CR,適用于溫度在-25℃-+60℃地區)或采用天然橡膠(即NR,適用......

天津橋梁伸縮縫焊接作業過程中要注意哪些呢? 2024-06-22

橋梁伸縮縫焊接作業過程中要注意哪些呢?1、焊接前不得打開伸縮裝置定位鎖。2、采用對稱點焊定位。在對稱焊接作業時伸縮縫每0.75~1m范圍內至少有一個錨固鋼筋與預埋鋼筋焊接,焊接長度應符合設計要求。兩側完全固定后就可將其余未焊接的錨固筋完全焊接,并穿橫筋進行焊接加固,確保錨固可靠,不得在橫梁上任意施焊,以防變形。3、焊接作業過程中,邊焊邊用3m直尺檢查縱橫向平整度及順直度。焊接完畢后,全面檢查一次,必要時進行調整。4、拆除鎖定夾具,檢查驗收合格后,進行下一道工序。GQF-E型橋梁伸縮縫中間橡膠密封條其技術要求:采用氯......
