Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0012] Such as figure 2 As shown, the anti-fall beam device of the present invention comprises a platform buttress 3 and a platform crossbeam 1 fixed on the support 2 at the top of the platform buttress 3, a groove 6 is arranged between the platform buttress 3 and the platform crossbeam 1, and the concave Anti-collision structure 5 is installed in groove 6, and anti-collision structure 5 is a rubber strip. The platform crossbeam 1 extends downward along the part protruding from the platform pier in the direction of the cross bridge, and the direction of the cross bridge is as follows: figure 2 As shown in the direction of the middle arrow, there is a groove 6 at a certain distance between the extension of the platform beam 1 an...

Abstract

The invention belongs to the technical field of bridge structures, and particularly relates to an anti-falling beam device. The anti-falling beam device comprises a platform buttress and a platform beam fixed on a support on the top of the platform buttress, wherein a groove is arranged between the platform buttress and the platform beam, and an anti-collision structure is installed in the groove. The anti-falling beam device is applied to small structures or areas with low seismic intensity. The designing method that the structure is slotted is adopted, an anti-collision rubber bar is installed in the groove to replace an additionally arranged anti-falling beam check block, economization is realized, complicated work of maintenance and replacement of conventional anti-falling beam steel structures is avoided, structure reliability is ensured, practical value is high, reinforcing and maintaining investment in the small structures is reduced, and the device plays an important role in protecting the anti-falling beam steel structures from corrosion failures during the service period.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and in particular relates to an anti-falling beam device. Background technique [0002] my country is an earthquake-prone country, especially in the three seismically active regions of North China, Northwest China, and Southwest China. There are examples of beam damage caused by earthquakes. The damage caused by falling beams is bound to cause serious traffic interruption, delay rescue, and cause huge losses. In my country's seismic design code, it is stipulated that in order to prevent vertical and horizontal beams from falling, anti-falling beam structures such as stoppers, anchor bolts, and steel brackets are adopted. In actual design, anti-seismic blocks are widely used to prevent beams from falling laterally. These structures are additional facilities in addition to the structure itself. The conventional anti-drop beam adopts steel structure, such as figure 1 Shown is a schemat...
