The technical scheme is that the structure for preventing the supporting articulation brackets from generating the bevel angle cracks when installing the arc-shaped gate comprises the supporting articulation brackets connected on gate piers at two sides, wherein the arc-shaped gates are supported on the supporting articulation brackets, the first-stage pre-buried steel plate and foundation bolts are pre-buried on the supporting articulation brackets and are connected, a second-stage steel plate is welded on the first-stage pre-buried steel plate, and metal construction is arranged on the lower portion of the second-stage steel plate and is welded and fixed with the first-stage pre-buried steel plate and the second-stage pre-buried steel plate. The structure for preventing the supporting articulation brackets from generating the bevel angle cracks when installing the arc-shaped gate is characterized in that cracking-limiting steel plate is pre-buried on the opposite-angle positions of the first-stage pre-buried steel plate, wherein two sides of the cracking-limiting steel plate are welded with rebar, and the rebar is also pre-buried inside the concrete of the supporting articulation brackets. The structure for preventing the supporting articulation brackets from generating the bevel angle cracks when installing the arc-shaped gate is applied to hydraulic and hydroelectric engineering and the like.
Description
Technical field
The utility model relates to a kind of Segment gate that prevents and props up the structure in hinge bracket generation crack, oblique angle when installing.Be applicable to Hydraulic and Hydro-Power Engineering etc.
Background technology
In Hydraulic and Hydro-Power Engineering, for the larger discharge orifice of head, Service gate generally adopts Segment gate, and Segment gate supports on a hinge bracket.Prop up the hinge bracket by embedding anchor bolts first phase steel plate, Segment gate is installed by the second stage of steel plate and first phase pre-embedded steel slab and is welded, and is hinged by stone bolt and radial gate support on the second stage of steel plate again.If the total water pressure of Segment gate is larger, a hinge bracket size and first phase pre-embedded steel slab size are also larger, and pre-embedded steel slab is subjected to concrete constraint corresponding also large.In the radial gate support hinge installation process, second phase steel plate and member thereof and a hinge bracket first phase pre-embedded steel slab weld together, owing to causing first phase pre-embedded steel slab temperature to raise during welding, the distortion of first phase pre-embedded steel slab is retrained by surrounding concrete, can produce larger stress, cause the stressed variation of concrete Shallow crack to occur, the crack generally occurs in four diagonal positions of first phase pre-embedded steel slab, extends with the miter angle direction, and particularly two diagonal positions of side more are prone to the crack near water.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of Segment gate that prevents simple in structure, easy construction to prop up the structure in hinge bracket generation crack, oblique angle when installing, to strengthen position, radial gate support hinge bracket first phase pre-embedded steel slab diagonal angle concrete rigidity.
The technical scheme that the utility model adopts is: a kind of Segment gate that prevents props up the structure in hinge bracket generation crack, oblique angle when installing, comprise a hinge bracket that is connected on the gate pier of both sides, Segment gate supports on a hinge bracket, pre-buried first phase pre-embedded steel slab links to each other with stone bolt and both on the bracket cutting with scissors corresponding to propping up of Segment gate installation position, first phase pre-embedded steel slab surface and a hinge bracket flush, the second stage of steel plate of welding on the first phase pre-embedded steel slab, second phase steel plate bottom is provided with the hardware of fixing with first phase pre-embedded steel slab and the second stage of Plate Welding, it is characterized in that: the pre-buried limit in position, described first phase pre-embedded steel slab diagonal angle is split steel plate, this limit is split steel plate both sides welded reinforcement, and reinforcing bar is embedded in the concrete of hinge bracket section equally in advance.
Described limit is split steel plate and is rectangular in shape, two length of side 15cm, and thick 10mm, length of embedment is 20cm.
Described bar diameter 8mm, long 30cm, spacing 5cm, an end and limit are split Plate Welding, are embedded in advance in the concrete of hinge bracket.
The beneficial effects of the utility model are: the utility model can improve the arc door and prop up the concrete rigidity in hinge bracket position, first phase pre-embedded steel slab diagonal angle.
In the utility model between first phase pre-embedded steel slab and the second stage of steel plate weld seam welding carry out in certain sequence, and every weld seam weld interval 15min, temperature does not continue to raise when guaranteeing the pre-embedded steel slab welding, avoids producing the crack because the Plate Welding variations in temperature causes position, first phase pre-embedded steel slab diagonal angle to prop up the hinge bracket in the Segment gate installation process.
