Bridge expansion joints of power transmission principle is parallel to the direction of the beam bridge joints, while the beam direction at a certain angle and diagonal seams supporting beam and displacement control box telescopic device supporting transmission mechanism, that is, when the beam phase When connected to one side of the beam expansion, expansion joints staggered diagonal support beams and the beam angle changes Maurer d60 type bridge expansion joints, and in the same direction 梁发生 edge beam and telescopic displacement, and make each article sutural gap substantially uniform, shown in Figure 5-13. The allocation of the beam and the supporting beam interaction force shown in Figure 5-14. Bridge expansion joints, in the matter of a few beams, the only set a diagonal support beam in the lower portion of the beam, the pitch is generally oblique supporting beams around 1.8m, it can root diagonal support beams minimum number, thus reducing the size of the displacement of the structure of the control box. About the design, and the effects may be looking to bring the bridge structures earthquake, so far, have been observed among consider seismic force in the world's most intense freezer earthquake in southern counties, the single over the seismic force the role of bridge expansion joints due to the complex and unpredictable vibration and seismic structural damage to the surrounding area of ??construction, bridge expansion joints must not exceed the assumed negative seismic force and displacement on the bridge deformation possibilities. Bridge expansion joints unexpected events such as a reliable construction bridge expansion joints 80 type price, take appropriate shown to prevent the falling beam device is necessary, moreover, to the holder of the Class A used set of deformation limit positioning device and connection protection, but did not prevent Luo Liang devices, expansion joints, but in order not to arrange for the placement of the table to understand the narrative. Prevent basic considerations of bridge method, based on the type of bridge and support conditions, bridge expansion joints will involve induction conditions, should not prevent the constraints of bridge bearing deformation shaped steel bridge expansion joints mf80, the amount of movement and rotation, bridge expansion seam while not give future maintenance management hindrance, especially in light of past experience, it is necessary for the following bridges research resources. gqfc40 type single slit shaped steel expansion joints | joints | ho-ho Rubber pass by Hengshui Rubber Company.
