Abstract
The utility model discloses a ladle arc door support structure, include gate pier concrete and set up the radial gate support on gate pier concrete, radial gate support surface is provided with radial gate support outsourcing steel lining, still is provided with gate pier outsourcing steel lining near gate pier concrete surface all around of radial gate support, radial gate support outsourcing steel lining and gate pier outsourcing steel lining are closely combined with gate pier concrete through the anchor steel sheet respectively, the transmission rib has been put to the equipartition between radial gate support outsourcing steel lining and gate pier outsourcing steel lining and the gate pier concrete. The utility model adopts the outer steel lining to replace the traditional anchor cable structure, avoids the trouble of maintenance after the prestress loss of the prestressed anchor cable in the existing gate pier of the arc door support, and is comparatively convenient to operate and maintain; meanwhile, most of the tensile stress of the neck part is borne by the steel lining, so that the tensile stress of concrete in the steel lining is greatly reduced; the utility model discloses simple structure, easily construction, the investment economizes, can extensively popularize and apply in hydroelectric engineering technical field.
Description
Technical field
The utility model relates to a kind of ladle arc door seat structure, belongs to hydroelectric project technical field.
Background technology
Arc door bearing and connected gate pier thereof are the key positions of water conservancy project earial drainage building, and can its reliability is directly connected to earial drainage building safety operating.Arc door susceptor design is the emphasis in Design of Hydraulic Structures, and structure is very important.Existing arc door bearing is mostly concrete structure, the Chinese patent being CN203716111U as publication number discloses a kind of high thrust arc door bearing, comprise concrete bearing and be arranged in the reinforcing bar in concrete bearing, described concrete bearing is made up of with the boss be positioned on base the base of cuboid, the bottom surface of boss is overlapping with base, in four sides, three sides adopt with bottom surface angled domatic, a side adopts the vertical surface with plane perpendicular, the end face of boss is parallel with bottom surface, this technical scheme overall volume reduces, and saves material.But because arc door bearing is concrete structure, therefore larger tensile stress can be produced at neck, and concrete tensile strength to compare compressive strength much smaller, in order to offset neck tensile stress, often need to arrange a large amount of reinforcing bars or large-tonnage prestress anchorage cable, arranging anchor cable not only expends huge, and there is the risk of loss of prestress.Therefore existing arc door bearing is desirable not enough, awaits perfect further.
Utility model content
For solving the problem, the utility model provides a kind of ladle arc door seat structure.Thus solve the larger tensile stress of existing arc door bearing neck generation, the problem that concrete tensile strength is lower.
The utility model is achieved by following technical solution.
A kind of ladle arc door seat structure, comprise pier concrete and be arranged at the arc door bearing on pier concrete, described arc door abutment surface is provided with arc door bearing outsourcing steel lining, also be provided with gate pier outsourcing steel lining on the pier concrete surface near arc door bearing surrounding, described arc door bearing outsourcing steel lining and gate pier outsourcing steel lining are combined closely respectively by anchoring steel disc and pier concrete.
Described arc door bearing outsourcing steel lining and be all furnished with power transmission rib between gate pier outsourcing steel lining and pier concrete.
Described power transmission rib is fan-shaped layout along arc door bearing thrust direction.
Described arc door bearing outsourcing steel lining and gate pier outsourcing steel lining all adopt steel plate to make.
Described steel plate is greater than the thickness away from arc door bearing neck location near the thickness of arc door bearing neck location.
The beneficial effects of the utility model are:
Compared with prior art, the utility model adopts outsourcing steel lining to replace traditional anchor cable structure, and avoid owing to carrying out the trouble of overhauling after arranging prestress anchorage cable loss of prestress in existing arc door bearing gate pier, operating maintenance also more for convenience; Simultaneously because neck tensile stress major part is born by steel lining, the concrete pulling stress of steel lining inside is greatly reduced.The utility model structure is simple, and be easy to construction, reduced investment, can in hydroelectric project technical field wide popularization and application.
Accompanying drawing explanation
Fig. 1 is facade arrangement schematic diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
In figure: 1-arc door bearing outsourcing steel lining, 2-gate pier outsourcing steel lining, 3-anchoring steel disc, 4-power transmission rib, 5-pier concrete, 6-arc door bearing.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, a kind of ladle arc door seat structure described in the utility model, comprise pier concrete 5 and be arranged at the arc door bearing 6 on pier concrete 5, described arc door bearing 6 surface is provided with arc door bearing outsourcing steel lining 1, also be provided with gate pier outsourcing steel lining 2 on pier concrete 5 surface near arc door bearing 6 surrounding, described arc door bearing outsourcing steel lining 1 and gate pier outsourcing steel lining 2 are combined closely respectively by anchoring steel disc 3 and pier concrete 5.Anchoring steel disc 3 is evenly arranged on pier concrete 5, and when making, anchoring steel disc 3 manufactures imperial claw-type structure, is convenient to arc door bearing outsourcing steel lining 1 and gate pier outsourcing steel lining 2 to combine closely with pier concrete 5 like this, makes its firm and reliable connection.Adopt the technical program, overcome existing arc door bearing neck and produce larger tensile stress and the problem that makes concrete tensile strength lower; In the utility model, pier concrete 5 and arc door bearing 6 surface is arranged in because arc door bearing outsourcing steel lining 1 and gate pier outsourcing steel lining 2 link into an integrated entity, arc door bearing 6 neck tensile stress major part is born by arc door bearing outsourcing steel lining 1 and gate pier outsourcing steel lining 2, thus the concrete pulling stress of steel lining inside is reduced greatly.
Described arc door bearing outsourcing steel lining 1 and be all furnished with power transmission rib 4 between gate pier outsourcing steel lining 2 and pier concrete 5.
Described power transmission rib 4 is fan-shaped layout along arc door bearing 6 thrust direction.Power evenly can be delivered in pier concrete 5 like this.
Described arc door bearing outsourcing steel lining 1 and gate pier outsourcing steel lining 2 all adopt steel plate to make.Structure is simple, draws materials conveniently, is convenient to implement.
In order to arrive good tension effect, described steel plate is greater than the thickness away from arc door bearing 6 neck location near the thickness of arc door bearing 6 neck location.Namely thicker near neck location steel lining, thinner away from neck location steel lining.
