Abstract
The utility model discloses a protective isolation platform above a railway operation line. The protective isolation platform is characterized in that the platform comprises a concrete bearing platform and a steel pipe column, the bottom end of the steel pipe column is inserted into the concrete bearing platform and is in rigid connection with concrete bearing platform, a longitudinal beam is erected above the steel pipe column along the direction of the railway operation line, a beam is paved on the longitudinal beam, and a distribution beam is arranged on the beam in welding mode. The protective isolation platform has the advantages of being simple in structure, high in stability, reasonable in construction, simple and convenient to mount and demount and the like.
Description
Technical field
The utility model building engineering field, particularly a kind of railway operation line top protection isolation platform.
Background technology
Along with country strengthens the investment construction to infrastructure, a large amount of rail yards, station project for renovation and expansion are emerged in large numbers.In field, station, station rebuilding and expansion of the of the existing enterprises process, all can relate to the construction of operation line; Electric railway operation line top contact net is 2.15 ten thousand volts of high-voltage lines, and construction wrong is prone to cause railway network interruption accident, will have influence on the rail track transportation; Cause the obstruction and the paralysis of train; Some railway main arteries particularly, the passenger and freight throughput rate is huge, and the economic loss that of short duration line interruption causes reaches up to ten million units.Near the construction conventional railway operation line adopts measures such as color steel, shellfish thunder frame, concrete structure protection canopy to isolate, but these measures stability with take tear open exist understable, take the problems such as loaded down with trivial details of tearing open.
The construction of operation line top protection isolation platform mainly is on conventional Construction of Steel Structure technology basis; Consider to close on the influence of operation line construction; Emphasis be reduce to install with remove work progress in to the influence of the relevant pipeline of operation line, equipment and high pressure contact net, install simultaneously and remove that construct need the skylight operation, main points are more; There is discontinuity in construction, must guarantee protection isolation platform structural safety.
Summary of the invention
The purpose of the utility model is to overcome defective of the prior art; Specific (special) requirements to protecting when passing through at a high speed in conjunction with railroad train; A kind of railway operation line top protection isolation platform is provided, have simple in structure, stability is high, structure rationally, install and remove advantages such as easy.
A kind of railway operation line top protection isolation platform; It is characterized in that said platform comprises concrete bearing platform and steel pipe column, insert in the concrete bearing platform steel pipe column bottom; Be rigidly connected with concrete bearing platform; Above steel pipe column, set up longeron along railway operation line direction, laid crossbeam above the longeron, distribution beam is located on the crossbeam through welding.
Further, the strength grade of concrete of said concrete bearing platform is C30.
Said steel pipe column is a 426mm*6mm spiral steel column; The steel pipe column spacing is preferably 10.4 meters.
Said steel pipe column top is provided with flange, and longeron is fixed on the steel pipe column through bolt and flange.
Said longeron is preferably 900H shaped steel.
Said crossbeam is preferably 900H shaped steel, and laying spacing is 3.5 meters, through bolt on longeron.
Said distribution beam is preferably channel-section steel, and spacing is 1.5 meters.
The operation line top protection isolation platform of the utility model is the light-duty frame construction of steel work, and main member comprises: concrete bearing platform, steel pipe column, longeron, crossbeam and distribution beam have the following advantages:
(1) structure is reasonable, and structural stability is high.The platform of the utility model can satisfy the train passage load requirement fully through structure design, checking computations, can outside the safe distance scope, effectively isolate contact net, avoids the contact net loss of power accident.
(2) simple in structure, it is convenient to construct, and installs and remove easy, has avoided the drawback of traditional protection isolation platform long construction period; And the characteristics that combine main points to construct, can carry out segmentation installation, segmentation dismounting.
Description of drawings
Fig. 1 is the elevation of the utility model protection isolation platform.
Fig. 2 is the sectional drawing of railway operation line top protection isolation platform.
To combine accompanying drawing that the utility model is done detailed introduction below.
The specific embodiment
Railway operation line top protection isolation platform shown in Fig. 1-2; The protection platform base adopts 1500*1500*700 cast-in-situ concrete cushion cap 1; Steel pipe column 2 (426mm*6mm spiral steel column) spacing is 10.4m, adopts with concrete bearing platform to be rigidly connected, and steel pipe column 2 is imbedded 500mm in the concrete; Footing utilizes 8 φ 20 fixing, and strength grade of concrete is C30.
900H shaped steel longeron 3 is set up along railway operation line direction in steel pipe column 2 tops.Flange (600*600*40) is established on steel pipe column 2 tops, and H shaped steel longeron is established punched steel plate (600*600*40) and adopted the bolt of 4 φ 20mm to be connected with the capital flange in the steel pipe column junction.
Lay crossbeam 4 above the longeron 3.Crossbeam adopts 900H shaped steel, and the laying spacing is 3.5m, and span is 25m.Guarantee to be connected through bolt with the reliable of longeron.
Distribution beam 5 adopts 18#, 16#, 14# channel-section steel, and 1.5 meters of spacings adopt the form of full shop, through spot welding assurance and crossbeam relative slippage do not take place.
The operation line top protection isolation platform of the utility model has the following advantages:
(1) structure is reasonable, and structural stability is high.The platform of the utility model can satisfy the train passage load requirement fully through structure design, checking computations, can outside the safe distance scope, effectively isolate contact net, avoids the contact net loss of power accident.
(2) simple in structure, it is convenient to construct, and installs and remove easy, has avoided the drawback of traditional protection isolation platform long construction period; And the characteristics that combine main points to construct, can carry out segmentation installation, segmentation dismounting.
