Abstract
A bridge railway sound barrier steel stand column convenient to overhaul and maintain is composed of an H-shaped steel column, a column bottom plate, a stiffening plate and a reinforcing plate, wherein the H-shaped steel column is welded on the column bottom plate, and the stiffening plate and the reinforcing plate are welded at an included angle of the H-shaped steel column and the column bottom plate. The utility model discloses a triangular strength plate and the mode of reinforcing plate guarantee the structural strength of column bottom plate, have improved the corrosion resistance and the durability of steel stand simultaneously.
Description
Technical Field
The invention belongs to the field of environmental protection, and particularly relates to a railway sound barrier steel upright on a bridge, which is a steel upright convenient to inspect on the inner side of a railway of the bridge, so that the personal safety of maintainers is ensured, and the strength of a steel column and the noise reduction effect of a sound barrier are not influenced.
Background
Conventional bridge sound barrier is after the construction is accomplished, inspection stage or use-in a period before commissioning, the not hard up condition of rag bolt that sound barrier steel stand and basis are connected can appear in the part, need tighten up the reinforcement once more, nevertheless rag bolt generally distributes in the both sides of sound barrier steel stand, bolt that leans on the iron road side can directly overhaul the reinforcement at the steel stand, and the rag bolt in the steel stand outside is in the outside of sound barrier, maintenance personal need turn over the outside and maintain during the maintenance, the high few meters that have of bridge height, high tens of meters, maintenance personal is in high altitude construction, it is big to overhaul the degree of difficulty, the safety risk is high. Also there is similar steel stand on the market, has added the steel support of a take the altitude in the bottom of steel stand, separates the rag bolt of fixed steel stand in the inboard of bridge, nevertheless because the steel support has taken certain sound insulation box area, therefore this kind of structure can produce certain influence to holistic syllable-dividing effect.
Disclosure of Invention
The invention aims to provide a bridge sound barrier steel upright post which is safe and reliable in structure and convenient to maintain, can improve the construction and installation efficiency on the basis of not influencing the noise reduction effect, and fundamentally solves the huge safety risk caused by later maintenance.
In order to achieve the above object, the present invention adopts the following solutions: adopt the steel stand to weld at the unilateral of column bottom plate, guarantee that exposed rag bolt all faces the railway side, installation that can be convenient and the maintenance in later stage, can not produce any influence to the installation of the box that gives sound insulation in earlier stage simultaneously.
A bridge railway sound barrier steel stand column convenient to overhaul and maintain is composed of an H-shaped steel column, a column bottom plate, a stiffening plate and a reinforcing plate.
H shaped steel post is the beading on the column bottom plate, ensures simultaneously that the reservation bolt hole on the column bottom plate distributes in one side of H shaped steel post, guarantees the later stage at the inboard alright installation and maintenance to the rag bolt of connecting of bridge.
The bolt hole that the column bottom plate was reserved is the slotted hole, and the adjustment of the later stage steel stand of being convenient for makes up the error of basic interval.
The stiffening plate is a triangular plate and is welded at an included angle between the H-shaped steel column and the column bottom plate, the H-shaped steel column is eccentric in welding of the column bottom plate, eccentric stress of the column bottom plate is uneven, stress balance of the column bottom plate is guaranteed through stress transmission of the stiffening plate, and strength is improved.
The reinforcing plate is welded at the outer edge of the stiffening plate and is welded with the H-shaped steel column and the column bottom plate simultaneously, the strength of the stiffening plate is improved, the reinforcing plate is welded along the outer edge of the triangular stiffening plate and has a certain inclination, rain and snow can be prevented from accumulating, freezing and thawing can be avoided, the corrosion resistance and the durability are improved, the H-shaped steel column, the stiffening plate and the column bottom plate are enabled to be a stressed whole, and the stiffening plate is prevented from being unbalanced due to large stress of the steel column.
Under the prerequisite that does not influence noise reduction effect, at the inboard alright installation of bridge and a bridge sound barrier steel stand of overhaul maintenance, guarantee maintenance personal safety, through the mode of triangular strength plate and reinforcing plate, guarantee the structural strength of column bottom plate, improved the corrosion resistance and the durability of steel stand simultaneously.
Drawings
Fig. 1 is a view of the assembly of the sound barrier.
FIG. 2 is a structural view of the steel column of the present invention.
In the figure, 1, steel columns, 2, a sound insulation box, 3, foundation bolts, 4, H-shaped steel columns, 5, column bottom plates, 6, stiffening plates, 7 and reinforcing plates.
The specific implementation mode is as follows:
a certain section of viaduct high speed railway passes through the residential area, and the noise that produces has produced certain influence to resident's life near, needs to build the noise barrier noise reduction, reduces the influence to resident near, because the bridge is too high, requires the sound barrier to be in the construction completion back, and debugging in earlier stage and later maintenance all can be accomplished at the bridge inboard is whole, must not overhaul in the sound barrier outside to guarantee personal safety. The bridge is built, and anchor bolts for mounting the sound barrier are reserved on two sides of the bridge.
In order to meet the requirements, the invention adopts a steel upright post structure convenient for maintenance, the steel upright post ① consists of four parts, namely an H-shaped steel post ④, a post bottom plate ④ 0, a stiffening plate ④ 1 and a stiffening plate ④ 2, the H-shaped steel post ④ 3 is firstly welded on one side of the post bottom plate ⑤, four reserved bolt holes on the post bottom plate ⑤ are ensured to be distributed on one side of the H-shaped steel post ④, then the stiffening plate ④ 4 with certain size and height is welded at the joint of the flange on the side of the H-shaped steel with the reserved holes and the post bottom plate, so that the strength of the upright post is improved, the uniform stress of the post bottom plate ⑤ is ensured, and meanwhile, in order to prevent the stiffening plate ⑥ from being unstable, the H-shaped steel post ④, the stiffening plate ⑥ and the post bottom plate are simultaneously welded by the stiffening plate ⑦ with the same width as the flange.
And (3) installing the welded steel stand columns at two ends of a bridge railway through foundation bolts on site, finely adjusting the installed steel stand columns through long round holes reserved in a column bottom plate, enabling all the foundation bolts to face the inner side of the railway, adjusting and positioning, fixing firmly by using nuts ③, inserting sound insulation boxes between the steel stand columns, and completing the installation of the whole sound barrier engineering.
The condition maintenance worker who inspection preparation before the commissioning and later stage appear that the bolt is not hard up can in time maintain at the railway inboard, and the perfect danger of solving outside bolt and unable maintenance or high altitude construction also can not influence the installation of bottom sound-proof box ② simultaneously, can not produce any influence to holistic noise reduction effect.
