Description
Technical field
The utility model relates to concrete strengthening applied technical field, especially a kind of external tendon ruggedized construction.
Background technology
Due to the shock of hull, lower edge concrete is damaged, part concrete comes off, there is longitudinal through crack, main reinforcement seriously corrosion, during reinforcing, first loose concrete is cut, to become rusty clearly process with wire brush, extension mould concreting is adopted to repair complete, then external prestressing strengthening is applied, reinforce axle casing supporting capacity to require to bring up to ten Pyatyis, or require to reach very high, because bridge bears larger vibration load for a long time, fatigue effect can cause the intermediate plate in ground tackle to loosen, ground tackle is even caused to lose anchor, bridge stability and safety can be reduced, and reduce the second consolidation time, reduce the life-span, occur for preventing this type of accident, the rigidity of structure can also be increased, reduce the amount of deflection that structure is excessive, the stress that release component is inner excessive, the geometry of adjust structure and stress, these are all the effects that other reinforcement means cannot realize.Therefore, pin two pairs of the problems referred to above we a kind of external tendon ruggedized construction is proposed.
Utility model content
Prior art can not meet the needs of people, for making up prior art deficiency, the utility model aims to provide a kind of easy construction, save material, reduce cost, there is reinforcing, unload and reduce the effect of structural internal force, effectively can improve the service behaviour of girder at serviceability limit stage, crack width is narrowed, and amount of deflection obviously reduces, and enhances the external tendon ruggedized construction of the durability of structure.
For achieving the above object, the utility model by the following technical solutions: a kind of external tendon ruggedized construction, at least comprises diagonal bar bundle, turns to floor, bearing, steel plate, horizontal bar bundle, steering block and anchor device; Described steering block be arranged on steel plate lower end and with steel plate compact siro spinning technology; Described steel plate to be arranged in the middle of horizontal bar bundle and steering block and to connect with horizontal bar bundle; Described horizontal bar bundle is arranged on and turns to floor lower end and be closely connected; The described floor that turns to is symmetricly set on inside diagonal bar bundle; Described anchor device is arranged on diagonal bar bunchy top end and tightens close interlocking with diagonal bar; Described diagonal bar bundle is connected between anchor device and steering block and lower end and steering block immediately; Described bearing is symmetricly set on steering block both sides.
As optimisation technique scheme of the present utility model: be provided with diagonal bar bundle between described anchor device and steering block, the firm steering block of vertical direction; Horizontal bar bundle and steel plate is provided with between described two steering blocks, and fixing steering block.
Compared with prior art, the beneficial effects of the utility model are: external tendon reinforcing method in use, there is reinforcing, the effect of unloading and reduction structural internal force, load standard can be reached after reinforcing, consolidation effect shows very much, effectively improve the service behaviour of girder at serviceability limit stage, crack width narrows, amount of deflection obviously reduces, enhance the durability of structure, in addition, external prestressing strengthening technology is a kind of active enforcement technology, not only new construction can be applied to, be more suitable for the rebuilding and reinforcement of old structure, its structural configuration is flexible, safe and reliable, particularly can realize adjusting rope and changing rope under structure normal operation, the incomparable advantages of other form of structure, with its easy construction, save material, reduce cost, conveniently overhaul and significantly effectively can improve the advantages such as bridge capacity, powerful effect has been played in the bridge construction and reinforcing process of the new period, except improving structural-load-carrying capacity, the rigidity of structure can also be increased, reduce the amount of deflection that structure is excessive, the stress that release component is inner excessive, the geometry of adjust structure and stress, these are all the effects that other reinforcement means cannot realize, practical, be applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of external tendon ruggedized construction, at least comprises diagonal bar bundle 1, turns to floor 2, bearing 3, steel plate 4, horizontal bar bundle 5, steering block 6 and anchor device 7; Described steering block 6 be arranged on steel plate 4 lower end and with steel plate 4 compact siro spinning technology; Described steel plate 4 to be arranged in the middle of horizontal bar bundle 5 and steering block 6 and to connect with horizontal bar bundle 5; Described horizontal bar bundle 5 is arranged on and turns to floor 2 lower end and be closely connected; The described floor 5 that turns to is symmetricly set on inside diagonal bar bundle 1; Described anchor device 7 is arranged on diagonal bar bundle 1 top and closely rabbets with diagonal bar bundle 1; Described diagonal bar bundle 1 is connected between anchor device 7 and steering block 6 and lower end and steering block 6 immediately; Described bearing 3 is symmetricly set on steering block 6 both sides.
As optimisation technique scheme of the present utility model: be provided with diagonal bar bundle 1 between described anchor device 7 and steering block 6, the firm steering block 6 of vertical direction; Horizontal bar bundle 5 and steel plate 4 is provided with between described two steering blocks 6, and fixing steering block 6.
As construction precautions of the present utility model: the functional requirement steering block that should meet an anchor system anchoring and power transmission during construction is formed by Plate Welding, ensure effectively to transmit prestressing force; After structural concrete partial pressing supporting capacity implements prestressed stretch-draw to external tendon, under Suo Li effect, pin has the extruding force in drag-line direction to concrete hole wall, the size of pin will be consistent with concrete dimension of opening, strength grade of concrete, to meet the requirement of concrete partial pressing; Partial pressing's supporting capacity of anchor lower bolt steel is under Suo Li effect, and the anchor ring of ground tackle will produce extruding force to steel bolt, should in the rational plane of anchor lower bolt Surface Machining, and this plane should ensure that ground tackle is stablized stressed, ensure vertical with external tendon again; Pin should have its shear strain of enough bending resistances, shear resistant capacity and non-deformability and flexural deformation as far as possible little, guaranteeing that anchor ring is installed firmly can coordinate mutually with the rope force direction of prestressed cable.
