Description
Technical field
The utility model relates to a kind of gate pier ruggedized construction, and particularly dangerously weak reseroirs gate pier ruggedized construction, is applicable to Hydraulic and Hydro-Power Engineering.
Background technology
Some Hydraulic and Hydro-Power Engineerings that China 50, the sixties build, owing to being subject to, technical level, economic capability, construction technology limit at that time, and some reservoirs are long neglected and in disrepair, in dam is made regular check on, often find that some engineering release floodwatering facilities are as spillway pier can there are the following problems:
(1) according to existing specification, spillway pier concrete strength is on the low side, does not meet structure durability requirement;
(2) there is comparatively multiple cracking in spillway pier, and it is not enough that limit splits reinforcing bar configuration, do not meet serviceability limit state requirement according to existing specification arrangement of reinforcement checking computations;
(3) calculate according to existing specification, it is not enough that flood spillway draws anchor reinforcing bar to configure, and do not meet ultimate limit states requirement.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, the gate pier ruggedized construction that a kind of structure is simple, safe and reliable is provided, be intended to improve the gate pier rigidity of structure, make it meet the requirement of structural-load-carrying capacity ultimate limit state and serviceability limit state.
The technical scheme that the utility model adopts is: a kind of gate pier ruggedized construction, comprises gate pier and bracket, it is characterized in that: the fan-shaped Tension Stress Zone of described bracket adopts the affixing steel plate reinforcement having through hole; Described affixing steel plate is welded with some steel ribs in arc door thrust direction, and is bonded in gate pier surface by the cement mortar of filling high strength; Also by plant anchor structural strengthening between described affixing steel plate and gate pier.
Described plant anchor structure is made up of bar planting anchor pole and anchor slab, anchor slab be square by welding be embedded in affixing steel plate, bar planting anchor rod anchored in gate pier and one end weld with anchor slab.
Described through hole is square hole, port size 10 × 10cm, pitch of holes 1.5 ~ 2m.
Described bar planting bolt diameter is Ф 20 ~ Ф 25mm, length is 2 ~ 3m, arrangement pitch is 1.5 ~ 2m; Anchor slab is of a size of 10 × 10 × 1.2cm, and surrounding cuts into 45 degree of oblique angles.
The beneficial effects of the utility model are: the utility model is at the fan-shaped Tension Stress Zone affixing steel plate reinforcement of gate pier, steel plate arranges 2 ~ 3 steel ribs in arc door thrust direction, high strength cement mortar is filled between gate pier and steel plate, simultaneously steel plate be anchored in the bar planting in gate pier and be welded to connect by the anchor slab of end, ensure that steel plate is stressed together with gate pier, after adopting this structural strengthening gate pier, improve gate pier rigidity, the requirement of gate pier plastic stage and serviceability limit state can be met.
Accompanying drawing explanation
Fig. 1 is that the utility model affixing steel plate arranges schematic diagram.
Fig. 2 is the utility model affixing steel plate anchoring schematic diagram.
Detailed description of the invention
As shown in Fig. 1 ~ Fig. 2, the present embodiment is a kind of gate pier ruggedized construction, be mainly used in the reinforcing of dangerously weak reseroirs, comprise gate pier 1, bracket 2, the affixing steel plate 3 being arranged in the fan-shaped Tension Stress Zone of bracket 2, the bar planting anchor pole 4 be anchored in gate pier 1, be welded on the anchor slab 5 of bar planting anchor pole 4 end, be filled in the cement mortar 6 of the high strength between gate pier 1 and affixing steel plate 3, and be arranged in 2 ~ 3 steel ribs 7 of affixing steel plate 3 arc door thrust direction.
In the present embodiment, affixing steel plate 3 generally adopts Q235-B or other model high-strength steel sheets, has and is of a size of 10 × 10cm, square through hole 3-1 that arrangement pitch is 1.5 ~ 2m, and this through hole is used for backfilling mortar early stage, and the later stage is as the anchor hole of affixing steel plate 3; The steel rib 7 of 2 ~ 3 high 5cm is furnished with in affixing steel plate 3 arc door thrust direction; The scope of this steel plate, thickness, and arranging of steel rib 7 is all determined by finite element checking computations.Plant anchor structure is made up of bar planting anchor pole 4 and the anchor slab 5 being welded on bar planting anchor pole 4 end, bar planting anchor pole 4 generally adopts HRB400, diameter is Ф 20 ~ Ф 25mm, arrangement pitch is 1.5 ~ 2m, and this anchor pole implants gate pier 2 ~ 3m, and adopts the anchoring of anchoring adhesive stick between hole wall; Anchor slab 5 generally adopts the square plate of Q235-B, and specification is 10 × 10 × 1.2cm, this anchor slab surrounding cutting 45 degree of oblique angles, and is embedded in the through hole 3-1 of affixing steel plate 3 by welding manner.
The detailed description of the invention of the present embodiment is: cut the thick Surface layer's concrete of about 10cm at the fan-shaped Tension Stress Zone of bracket 2, and the scope that cuts is laid scope according to affixing steel plate 3 and determined; Affixing steel plate 3 sticking veneer is polished metallic luster, external coating WSJ structure glue, be anchored in the fan-shaped Tension Stress Zone of bracket 2; Affixing steel plate 3 is bonded in gate pier 1 surface by the cement mortar 6 of filling high strength, and cement mortar 6 is filled closely knit by the through hole 3-1 of affixing steel plate 3, possess after some strength until mortar, arrange plant anchor structure by the through hole boring of this steel plate, anchoring affixing steel plate 3 and gate pier 1.
