The utility model belongs to the technical field of bridge structures, in particular to an anti-fall beam device. It comprises a platform support pier and a platform beam fixed on a support at the top of the platform support pier, a groove is arranged between the platform support pier and the platform cross beam, and an anti-collision structure is installed in the groove. The results of this utility model are applied to small structures or areas with relatively low seismic intensity. The design method of slotting on the structure itself is adopted, and anti-collision rubber strips are installed in the slots to replace the additional anti-falling beam stoppers. It is economical and avoids the cumbersome work of maintenance and replacement of conventional fall-proof beam steel structures, ensures the reliability of the structure, and has certain practical value. It reduces the cost of reinforcement and maintenance of small structures, and plays an important role in avoiding corrosion failure of the anti-fall beam steel structure during its service life.
Description
Technical field
The utility model belongs to the bridge construction technical field, is specifically related to a kind of anti-fall girder apparatus.
Background technology
China is earthquake a multiple country, particularly North China, northwest, southwestern three violent earthquake activity areas, have earthquake to fall example that beam destroys.The beam that falls destroys certainly will cause serious interruption of communication, has delayed rescue, and loss is huge.In China's earthquake resistant design code, stipulate, for preventing the vertical, horizontal beam that falls, take anti-fall beam constructions such as block, crab-bolt, steel bracket type.Then extensively adopt the antidetonation block to prevent from laterally falling beam in the actual design.These structures are the extra facility except structure self.Conventional anti-fall beam adopts steel work, is illustrated in figure 1 as horizontal anti-fall block design scheme schematic diagram of the prior art, and beam falling prevention stopping block 4 is steel work, adopts first pre-embedded steel slab, and the bolted mode in back is arranged between platform crossbeam 1 and the platform buttress 3.Steel work need have perfect anti-corrosion measure, otherwise can cause anti-fall beam measure to be lost efficacy, and needs to change, and the later maintenance expense has high input.
Be in the relatively low area of seismic fortification intensity for some small-scale structures or structure, adopt conventional anti-fall beam economical inadequately, then can pass through some special structural design, make structure not only stressed reliable, economical rationality again.
Summary of the invention
The purpose of this utility model is at above-mentioned technical problem, provide a kind of simple in structure, can avoid the anti-fall girder apparatus of the loaded down with trivial details work of conventional anti-fall joist steel structure maintenance and replacing again.
The technical solution of the utility model is: anti-fall girder apparatus comprises the platform buttress and is fixed on platform crossbeam on the bearing at platform buttress top, is provided with groove between described platform buttress and the platform crossbeam, and anti-collision structure is installed in the groove.
Further, described platform crossbeam extends downwards along the part that the cross-bridges direction is protruded the platform buttress, is provided with the groove of certain distance between the extension of platform crossbeam and the platform crossbeam side.
Further, described anti-collision structure is the rubber bar.
The utility model application of result is in small-scale structure or the relatively low area of earthquake intensity, the design that employing is slotted certainly on one's body in structure, crashproof rubber strip is installed in the groove, to substitute the extra beam falling prevention stopping block effect that arranges, not only economy but also avoided the loaded down with trivial details work of conventional anti-fall joist steel structure maintenance and replacing, guaranteed reliability of structure, can reach and prevent that the beam body from coming off, the effect of dissipation seismic energy to have certain practical value.The reinforcing maintenance cost that has reduced small-scale structure simultaneously drops into, and plays an important role to avoiding anti-fall joist steel structure to lose efficacy in the lifetime internal corrosion.
Description of drawings
Fig. 1 is the horizontal anti-fall block design scheme schematic diagram of platform of the prior art.
Fig. 2 utilizes the structural representation of platform crossbeam mode of grooving for the utility model.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, be convenient to be well understood to the present invention, but they do not constitute restriction to the present invention.
As shown in Figure 2, anti-fall girder apparatus of the present utility model comprises platform buttress 3 and is fixed on platform crossbeam 1 on the bearing 2 at platform buttress 3 tops, be provided with groove 6 between platform buttress 3 and the platform crossbeam 1, groove is installed anti-collision structure 5 for 6 li, and anti-collision structure 5 is rubber strip.Platform crossbeam 1 extends downwards along the part that the cross-bridges direction is protruded the platform buttress, and the cross-bridges direction is provided with the groove 6 of certain distance between the extension of platform crossbeam 1 and platform buttress 3 sides shown in the direction of arrow among Fig. 2.
The utility model achievement adopts the mode of slotting at the platform crossbeam, between the platform buttress 3 that arranges and platform crossbeam 1, anti-collision structure 5 is set, the extra beam falling prevention stopping block that arranges of cancellation, carry out particular design at the structure slotting position by bracket, and because the number of platform crossbeam is more, can resist lateral external forces jointly, make structure utilize the anti-fall beam facility of the alternative conventional scheme of self fluting, reduced beam falling prevention stopping block, reduced the later maintenance expense, not only economy but also avoided the maintenance of conventional anti-fall joist steel structure structure and the loaded down with trivial details work of replacing had been guaranteed reliability of structure.
