平面型橋梁伸縮縫

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(yǎng)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 joints refer to the expansion joints to meet the requirements of bridge deck deformation， usually between the two beam ends， between Liang Duan and abutment or the hinge position of the bridge. 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 setting of expansion joints， the railing and deck pavement should be disconnected.

伸縮縫按照性能及安裝方法可以分為：GQF-C型、GQF-Z型、GQF-L型、GQF-F型、其中GQF-MZL型數(shù)模式橋梁伸縮縫裝置，是采用熱軋整體成型的異型鋼材設計的橋梁伸縮縫裝置. 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， GQF-MZL型伸縮縫裝置是由邊梁、中梁、橫梁和連動機構組成的模數(shù)式橋梁伸縮縫裝置，適用于伸縮量80mm-1200mm的大中跨度橋梁.

Joints according to performance and installation methods can be divided into GQF-C type， GQF-Z type， GQF-L type， GQF-F type， GQF-MZL type model of bridge expansion joint device， is the overall design of special-shaped steel bridge expansion joint apparatus. The hot forming of GQF-C type， GQF-Z type， GQF-L type， GQF-F type jointless bridge the joint device is suitable for the expansion of the following 80mm， GQF-MZL type expansion joint device is composed of modular bridge expansion edge beam， beam， beam and linkage mechanism joint device， suitable for large and medium span bridge expansion of 80mm-1200mm.

公路橋梁伸縮縫裝置分為：模數(shù)式橋梁伸縮裝置和KS伸縮裝置以及TST彈塑體伸縮縫裝置

The expansion joints of road and bridge are divided into the modulus bridge expansion device and the KS expansion device and the TST elastic plastic expansion joint

一、模數(shù)式橋梁伸縮縫裝置

A， modulus bridge expansion joint device

模數(shù)式橋梁伸縮縫裝置分為：GQF-C型橋梁伸縮縫裝置、GQF-MZL型橋梁伸縮縫裝置

The expansion joint device of the model bridge type bridge is divided into GQF-C type bridge expansion joint and GQF-MZL bridge expansion joint

1、GQF-C型橋梁伸縮縫裝置特點：GQF-C型橋梁伸縮縫裝置采用整體熱軋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。

1， GQF-C type bridge expansion joint device features GQF-C type bridge expansion joint device adopts the whole hot r shaped steel， overcome the extrusion special-shaped steel straightness and set size uneven， low building height， homemade hot rolled profiled steel forming the overall height of only 50mm， simple structure， convenient installation， with comfort obviously， reliability and durability. It is convenient for the replacement of the old telescopic device， and it can also be used for the new bridge.

選用原則： 橋面鋪裝層厚度80mm 伸縮量80mm

The selection principle pavement thickness of 80mm the expansion amount is less than or equal to 80mm

2、GQF-MZL型橋梁伸縮縫裝置特點：MZL型伸縮縫裝置結構突出的特點是：由邊梁、中梁、橫梁、位移控制系統(tǒng)、密封橡膠帶等構件組成的系列伸縮裝置。該伸縮縫裝置的承重結構和位移控制系統(tǒng)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(tǒng)作法，這樣對大位移量伸縮縫裝置非常有利，減少了橫梁數(shù)量，使位移控制箱體積減小到小范圍，節(jié)約了鋼材。該結構還克服了斜向支承式伸縮縫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(xiàn)自鎖現(xiàn)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。

2， GQF-MZL type bridge expansion joint device features MZL expansion joint device structure outstanding characteristics are by side beam， middle beam， crossbeam， displacement control system， seal rubber belt and other components of a series of expansion device. Separate device load-bearing structure and displacement control system of the telescopic joint， the two forces do not interfere with each other， a clear division of labor， so as to ensure the safety of the force， and can achieve the uniform displacement， so that all beams of traditional practices in a displacement control box are supported on the same vertical beam， the telescopic the displacement of joint device is very beneficial to reduce the number of beams， the displacement of the control box volume is reduced to the minimum， saving steel. The structure also overcomes the harsh conditions that the inclined support expansion joint device requires high accuracy in processing and assembly. Otherwise， the four link structure is prone to self locking phenomenon， which affects the expansion and freedom and is not easy to ensure uniform displacement. The structure of the structure is both rotating and sliding. Therefore， the flexural， slope， oblique and wide bridges have strong adaptability， which can meet the requirements of the use of various bridge structures.
