Abstract
The utility model relates to a large member elastic gap-covering device which is characterized by being provided with an arched elastic plate, two sides of which are respectively connected with a rib plate, and each rib plate is fixed on a large member below a gap by two supports. At least two expanders are connected between the two rib plates. The elastic plate is an elastic stainless steel plate. The support is made from stainless steel, aluminium alloy or other metallic materials, and the arch on the arched elastic plate can be a single arch or multiple arches. The large member elastic gap-covering device has the advantages that: when gap distance between large members changes along with the temperature change, the elastic gap-covering device can cover the gap all the time, thus preventing air current from flowing in the gap when a train runs at high speed.
Description
Technical field
It is a kind of large-scale component elastomer cover seam device that the utility model relates to.
Background technology
Be to build at the high-speed railway of building at present by the mode of viaduct, viaduct mainly is to be spliced with large-scale component, the length of large-scale component generally has tens meters long, because the cause of expanding with heat and contract with cold, between large-scale component, must leave certain slit, allow large-scale component that certain extendable room can be arranged under variations in temperature.When train when running at a low speed, the slit is smaller to the influence of train operation; Continuous lifting along with train speed, the air velocity of train periphery also promotes thereupon, when the speed of train reached more than 300 kilometers/hour, air-flow will upwards be scurried from the slit fast, bump train bottom, cause noise, influence the comfortableness that the passenger rides in the railway carriage,, must cover this slit in order to solve the influence that operation produces to bullet train of large-scale component slit, and the spacing in this slit changes, and demands inventing a kind of elastomer cover seam device that can address the above problem urgently.
Summary of the invention
The purpose of this utility model be solve large-scale component slit on the existing high-speed railway viaduct bullet train by the time to the problem that influences of train, a kind of large-scale component elastomer cover seam device is provided.The utility model design large-scale component elastomer cover seam device is characterized in that: an elastic plate that is arch is arranged, respectively connect a gusset on the both sides of the elastic plate of arch, every gusset is by on two large-scale components that are supported and fixed on below the slit.Be connected with at least two expanders between two gussets.Elastic plate is the elastic stainless steel plate.Support is made by stainless steel, aluminium alloys or other metal material, and the arch on the elastic plate of arch can be single arch or multiple arch.Under the situation that the utility model has the advantages that the slit spacing of working as between the large-scale component to vary with temperature and change, can cover the slit all the time, stop train air-flow flowing in the slit when running at high speed.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
It is characterized in that among the figure: an elastic plate 1 that is arch is arranged, respectively connect a gusset 2 on the both sides of the elastic plate 1 of arch, every gusset 2 supports on 3 large-scale components 5 that are fixed on below the slit by two.Be connected with at least two expanders 4 between two gussets 2.Elastic plate 1 is the elastic stainless steel plate.Support 3 and made by stainless steel, aluminium alloys or other metal material, the arch on the elastic plate 1 of arch can be single arch or multiple arch.
During enforcement, a last gusset 2 is respectively welded on stainless steel elastic plate 1 both sides, on gusset 2, install two then and support 3, the utility model is installed in the slit between the large-scale component 5, and will support being connected of 3 lower end and large-scale component, in order to strengthen pulling force, two are supported 3 and can be and intersect the scissors setting, and two expanders 4 are installed between two gussets 2, the permanent position of expander 4 can be corresponding with the position of supporting 3.
When elastomer cover seam device is installed in large-scale component 5 slits, when large-scale component 5 was met cold contractions, the slit enlarged, and the elastic stainless steel plate 1 that is arch is expanded; And when large-scale component 5 expanded by heating, the slit diminishes, the elastic stainless steel plate pressurized that is arch, elastomer cover seam device can cover the slit of large-scale component 5 all the time, when bullet train passes through, even increase at the airflow on surface of large-scale component 5, the air pressure of periphery air-flow reduces, because the slit of large-scale component 5 is covered, and no longer produces the impact of air-flow to train, guarantees train occupant's comfort level to greatest extent.
Claims (5)
1. large-scale component elastomer cover seam device is characterized in that: an elastic plate that is arch is arranged, respectively connect a gusset on the both sides of the elastic plate of arch, every gusset is by on two large-scale components that are supported and fixed on below the slit.
2. by the described large-scale component elastomer cover seam of claim 1 device, it is characterized in that: between two gussets, be connected with at least two expanders.
