[Bridge] compression caulk joints advantages:? Telescopic part without the support load device located GQF-E80-type bridge expansion joints between the bridge deck and without fixed settings, simple structure. ? Driving comfort. ? Use a rubbery synthetic material and lightweight, tough. ? Can be installed GQF-D80 type bridge expansion joints after the project is completed, the construction easier. ? Patched only 10 to 20 hours, you can shorten the time closed to traffic. [Bridge expansion joints] Disadvantages:? Expensive. ? Many kinds of products GQF-F80 type bridge expansion joints, between poor quality and difficult to select appropriate varieties, poor cement at construction time shedding. [Bridge expansion joints] Maurer Maurer sewn seam body following two items:? Two parallel rails, anchor (Anchored) to its concrete deck on both sides of the rail with angle instead of depending on the circumstances. ? Preformed strip of synthetic rubber congestion in two parallel rail. (A) single combination Maurer seam (B) more than a combination of bridge expansion joints [Maurer] seam characteristics: (1) be able to withstand a direct effect of the wheel load, with high rigidity and durability, and can act on the girder vehicle load evenly dispersed and transferred to the structural design of the anchoring structure guillotine reasonable tendons, and anchor the bridge structure 梁连成 whole bridge expansion joints, so that the body together and bridge expansion joint device the force of the current bridge expansion joints [] Views on the device is designed (1) [] small span bridge expansion joints in bridges (such as within 20m of) should be no expansion joints. Fixed bearing rubber bearing, so piers elastic deformation and soil resistance to Taiwan after the temperature stress resistance (due to deformation length within 10m telescopic amount generally less than 5mm). You can also paving the road and bridge paving over, and then open a seam along the original 3 ~ 5cm wide and 2cm deep seam false, filled with asphalt oakum or other plastic material to prevent surface cracking. (2)] [bridge expansion joints, the bridge should adopt the W-type telescopic device, it has the following advantages: ① telescopic body is coupled with iron can not glue, and the use of pre-compaction of the rubber itself waterproof seam; ② scantlings small, the corresponding amount of material Province, construction convenient, low cost; ③ stretching deformation temperature play like elastic material properties of rubber. Under the effect of the external load is to take advantage of the arch structure. [Bridge expansion joints]. Comb comb slab slab structure for the two main jagged steel, its jagged intertwined, so when the retractable steel cross over, do not squeeze another. Vintage comb plate joints can not solve the water problem, but after the improved comb slab to solve this problem. [] Comb slab bridge expansion joints advantages:? Rugged durability. ? Driving beating small? There waterproof device will not cause leakage under the rain. ? Complex structure, easy construction, higher cost. ? When maintenance is not easy to be damaged.
