Abstract
The utility model relates to an arc gate which is suitable for dams. The arc gate comprises piers, gate grooves, slide ways and supporting bases. The arc gate is characterized in that an arc slide plate is connected between two sliding or rolling supporting bases which are arranged on two symmetrical piers, and besides, horizontal girder compression bars are distributed between the two sliding or rolling supporting bases. Brace bars which form truss girders are distributed among the concave surface of the arc slide plate and the horizontal girder compression bars. Because the utility model adopts an arc slide plate structure, the whole gate is under homogeneous stress, and a great deal of steel is saved. Because an upper and a lower adjacent junctions, the arc radiuses of which are different, are provided with a horizontal welded plate, the stressed stability of the slide plate is improved. The horizontal welded plate is connected with the compression bars through the brace bars, through which the truss girders are formed and the truss girders have stabler structure and more uniform stress.
Description
The utility model belongs to the gate technical field, specifically a kind of circular arc type gate that is arranged on the dam dam body.
At present, the gate that is applied on the dam dam body mainly contains Flat Sluice, beam type brake structure.Although two kinds of above-mentioned structure behavior in service are good, also there are some unfavorable factors, its major defect is that material can not make full use of, particularly shear force is zero in the middle of the flashboard in the sluice, does not need the shear force plate; And the shear force on both sides is maximum relatively, needs web, like this since material then can not utilize fully.And the last lower edge of beam type gate causes material not make full use of too.In sum, above-mentioned Flat Sluice, beam type brake structure complexity and structure is unreasonable, construction costs is high, waste of material is serious.
The purpose of this utility model provides a kind of simple and reasonable, stressed circular arc type gate that is evenly distributed.
The purpose of this utility model is achieved in that it comprises gate pier, gate base plate, gate slot, slip or rolling slideway, slip or roller support, it is characterized in that between slip on symmetrical two gate piers or roller support, being connected with a circular arc flashboard, between two slips or roller support, also be distributed with the cross beam type depression bar, be evenly equipped with the diagonal member of forming girder truss between circular arc flashboard concave surface and the cross beam type depression bar.
The utility model also is included in and is connected with the circular arc flashboard that two arc radius do not wait between two symmetrical slips or the roller support at least, and is that from top to down arc radius is tapering type ladder-type structure.Increase with the degree of depth that reduces along with water, water is to the also or else disconnected unfavorable factor that increases of the pressure of circular arc flashboard.
The utility model makes gate whole stressed even owing to adopt the circular arc type flashboard structure, has saved great deal of steel; Welding capacity obviously reduces than existing beam type lock, and along with the degree of depth of water increases, arc radius is reduced gradually, thereby reduced the pressure of water to the circular arc flashboard; Because up and down two are faced and there is a horizontal welding fishplate bar junction that arc radius does not wait mutually, thereby have improved the stressed stability of flashboard, form brace with the cross beam type depression bar and connects, the formation girder truss, structure stablizes more, stressed more even.Therefore the utlity model has simple and reasonable, save advantages such as steel 30-40%, cost are low, long service life.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation sketch of the present utility model
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the left view of Fig. 1
Shown in Fig. 1-3, among the figure 1 is that gate base plate, 2 is that gate pier, 3 is respectively arranged with slideway 4, roller support 5 for gate slot, in the inboard of gate slot 3, be connected with the circular arc flashboard 6 that three arc radius do not wait between the roller support in symmetrical two gate slots, and be that from top to down arc radius is tapering type ladder-type structure, also be provided with a horizontal welding fishplate bar 7 in the circular arc flashboard junction of facing mutually and arc radius does not wait; Between two roller supports, also be distributed with cross beam type depression bar 8, be evenly equipped with diagonal member 9 between circular arc flashboard concave surface and the cross beam type depression bar.The designing and calculating of this gate meets structural mechanics and Code for design of steel structures.Among the figure 10 is that the upstream sign, 11 of reservoir is the connection rod member of cross beam type depression bar in addition.The gate of reservoir also can adopt the identical circular arc flashboard of arc radius as required, and just the degree of depth along with water increases the also corresponding increase of the thickness of flashboard.
