GQF-F型橋梁伸縮縫-D80型橋梁伸縮縫裝置行業典范

橋梁伸縮縫指的是為滿足橋面變形的要求,通常在兩梁端之間、梁端與橋臺之間或橋梁的鉸接位置上設置伸縮縫。要求伸縮縫在平行、垂直于橋梁軸線的兩個方向,均能自由伸縮,牢固可靠,車輛行駛過時應平順、無突跳與噪聲;要能防止雨水和垃圾泥土滲入阻塞;安裝、檢查、養護、消除污物都要簡易方便。 在設置伸縮縫處,欄桿與橋面鋪裝都要斷開。

The bridge expansion joint refers to the expansion joint which is usually arranged between the two beam ends, between the Liang Duan and the abutment or the hinge position of the bridge to meet the requirements of the bridge deck deformation. Requirements of expansion joints in two directions parallel and perpendicular to the axis of the bridge, can free expansion, firm and reliable, the vehicle had to be smooth, no sudden jump and noise; to prevent rainwater and waste soil infiltration obstruction; installation, inspection, maintenance, eliminate dirt to be simple. At the expansion joint, the railing and the bridge deck should be disconnected.

橋梁伸縮縫一般有模數式橋梁伸縮裝置和KS伸縮裝置以及TST彈塑體伸縮裝置

At present, the bridge expansion joints of Changtai Hengshui Engineering Rubber Co., Ltd. generally have modulus type bridge expansion device and KS expansion device, and TST elastic plastic telescopic device

橋梁伸縮縫常見的幾種型號有c型,D型,E型,F型,異型伸縮縫的型號有很多,按照伸縮縫的性能及伸縮縫安裝方法,是采用熱軋整體成型的異型鋼材設計的橋梁伸縮縫裝置可分為;GQF-C型、GQF-Z型、GQF-L型、GQF-F型伸縮縫裝置適用于伸縮量80mm以下的的橋梁接縫;

Hengshui bridge expansion joint of several types of common C type, D type, E type, F type, there are many shaped expansion joint model, joint installation method according to performance and expansion joints, special-shaped steel bridge expansion is the overall design of the hot rolling forming joint device can be divided into; GQF-C type, GQF-Z type, GQF-L type, GQF-F type jointless bridge joint device is suitable for the expansion of 80mm or less;

GQF-C型橋梁伸縮裝置中間橡膠密封條其技術要求:采用氯丁橡膠(CR)密封橡膠帶的伸縮裝置適用與溫度為-25℃-+60℃地區.采用天然橡膠(NR)密封橡膠帶的[1]裝置適用于溫度為-40℃-+60℃地區

The technical requirements of the intermediate rubber sealing strip for GQF-C bridge expansion device: the rubber expansion device of chloroprene rubber (CR) is suitable for the region with temperature of -25 degrees -+60 degrees. The [1] device using natural rubber (NR) sealing rubber belt is suitable for the temperature of -40 degrees -+60 degrees centigrade

(2)、GQF-MZL型橋梁伸縮裝置特點:由邊梁、中梁、橫梁、位移控制系統、密封橡膠帶等構件組成的系列伸縮裝置。該伸縮裝置的承重結構和位移控制系統分開,二者受力時互不干擾,分工明確,這樣既保證受力時安全,又能達到位移均勻,使所有中梁在一個位移控制箱內均支承在同一根垂直橫梁上的傳統作法,這樣對大位移量伸縮裝置非常有利,減少了橫梁數量,使位移控制箱體積減小到最小范圍,節約了鋼材。該結構還克服了斜向支承式伸縮裝置要求加工和組裝精度相當高的苛刻條件,否則四連桿結構極易出現自鎖現象,影響伸縮自由和不易保證位移均勻的弊病。該結構各連接處均采用既能轉動又能滑動結構。所以,對彎、坡、斜、寬橋梁適應能力強,可滿足各種橋梁結構使用要求。

GQF-F型橋梁伸縮縫產品特點: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.適用于橋面鋪裝層厚度等于或大于80mm,伸縮量小于等于80mm的各種橋梁,既方便舊橋梁伸縮縫更換,又可供新橋梁修建選用.由于一些伸縮縫安裝不適就會產生跳車現象,不但在國內的公路橋梁上存在,在國外也尚未解決,因此,我們為了消除臺階,防止跳車,保持良好的路況,有關部門及施工單位采用了許多行之有效的措施與辦法,在動難逃很大程度上減少了橋梁伸縮縫處跳車病害。其中橋梁伸縮縫的安裝施工是公路橋梁建設中一項極為重要的施工項目,安裝質量的好壞直接影響到行車的平穩性和舒適性、大型橋梁的服務質量及使用年限。

The GQF-F type jointless bridge features: low building height, homemade hot rolled profiled steel forming the overall height of only 50mm, has the advantages of simple structure, convenient installation, obvious reliability, comfort and durability. Suitable for pavement thickness is equal to or greater than 80mm and less than or equal to a variety of bridge expansion of 80mm, both for the convenience of the old bridge joint replacement, and can be used for the new bridge built in use. Due to the installation of discomfort will produce jumping phenomenon not only exists in the expansion joint, the domestic highway bridge, in foreign countries also have not been solved. Therefore, we in order to eliminate the step, prevent bump, keep a good road, the relevant departments and construction units by many effective measures and methods, in can largely reduce the bridge expansion joints bump. The installation and construction of bridge expansion joints is a very important construction project in the construction of highway bridges. The quality of installation directly affects the stability and comfort of driving, the service quality and service life of large bridges.

公路橋梁伸縮縫是一種設置于橋梁上部結構活動端、橋面斷縫處的伸縮裝置。安裝伸縮裝置的作用是用以保證上部結構在溫度變化、混凝土收縮和徐變,以及荷載作用下,在該處的變位能夠實現,而不產生額外的附加內力,并能保證行車平順。通常國內的橋梁伸縮縫都設置在上部結構的活動端和橋臺,以及各聯(孔)上部結構銜接處。一般公路橋在車行道和人行道上沿橋的橫方向通長設置,欄桿在接縫處亦須中斷以保證結構的自由變位,避免拉裂;在接縫處的橋面防水層仍應妥善鋪設,防止雨水侵蝕承重結構。如采用敞口式的橋梁伸縮縫,還應考慮便于清除污物,并在縫下設置截水和引水裝置,使積水排出橋外。國內的中型、大型鐵路橋同理也需設伸縮縫,在道碴橋面中,應考慮防止道碴墜落縫中的措施。
