Abstract

The invention provides a novel energy-dissipation anti-dropping beam device. The novel energy-consumingdissipationate A (1), a connecting plate B (2), an E-shaped energy-dissipation element (3), a high-strength bolt (4), a main beam pre-embedded part (5), a pier pre-embedded part (6), restraining groove holes (7) of the connecting plate B (2) and restraining groove holes (8) of the connecting plate A (1), wherein the restraining groove holes (7), which are matched with the quantity and positions of cantilever limbs of the E-shaped energy-dissipation element (3), are machined on the connecting plate B (2); the length of the restraining groove hole (7) in the middle is smaller than the length of the restraining groove holes (7) at the two ends; the matched restraining groove holes (8) are machined at the positions, corresponding to the restraining groove hole (7) in the middle of the connecting plate B (2), on the connecting plate A (1), and matched screw holes or through holes are machined at the positions corresponding to the restraining groove holes (7) at the two ends. The novel energy-dissipation anti-dropping beam device has the characteristics of reasonable structural form, low manufacturing cost, easiness of mounting and replacing, good energy-dissipation performance and the like and has a good application prospect.

Description

technical field [0001] The invention relates to a bridge anti-seismic and shock-absorbing technology, especially a novel energy-dissipating anti-drop beam device in the passive energy-dissipating shock-absorbing control and position limiting of bridge structures, specifically a bridge structure that can provide additional damping It is a new type of energy-consuming anti-fall beam device that reduces the seismic response of bridges, limits the relative displacement between pier-beam (or platform-beam), and finally prevents beam fall. Background technique [0002] Aseismic resistance of bridges is a relatively complicated problem. Compared with building structures, due to the structural characteristics of bridges, seismic problems and building structures have their own unique aspects. Expansion joint devices are non-structural components that are designed to accommodate the effects of structural material shrinkage, creep, and external environmental temperature changes. Its n...

Problems solved by technology

At present, the cable-type anti-fall beam device and oil damper energy-dissipating device are mainly used. The cable-type anti-fall beam device will only work when the relative displacement between the pier (platform) beams exceeds its non-working length. , and can only play a limiting role. Although the oil damper can produce energy consumption, it is difficult to be widely used because it is prone to oil leakage and expensive. The anti-drop beam device that can limit the position has become a top priority
