Description

The building progressive collapse-resisting hardened system that HPFL is combined with steel plate and method

Technical field

The invention belongs to construction engineering technical field, be specifically related to building progressive collapse-resisting hardened system that a kind of HPFL is combined with steel plate and method.

Background technology

Along with the raising of China's economic level, the reinforcing technique of reinforced concrete building there has also been very large development.Current China structural strengthening transformation industry becomes one of field of civil engineering main industries.Due to reasons such as building Change of use, seismic Damage, shock and explosive damages, building is often faced with the risk of continuous collapse.Current conventional reinforcing technique has: the reinforcing of reinforcement High Performance Mortar, steel-bonded reinforcement, FRP reinforcing, increasing section reinforcing etc., but reinforces bending resistance, shear-carrying capacity that target is generally limited to improve beam; Improve the axial compression of post, bias performance; And improve the shock resistance etc. of post or node.And the progressive collapse-resisting of structure is reinforced, it focuses on the Path of Force Transfer rebuilding structure, improve the holistic resistant behavior of structure, thus make structure still possess good collapse resistant capacity when local supporting member breakage, hardened system of the prior art and method can not be applicable to building progressive collapse-resisting and reinforce, and make a concrete analysis of as follows:

(1) FRP reinforces

FRP reinforce there is good advantage in structural strengthening: fibre reinforced composites have corrosion-resistant, high strength, quality are light, thickness is thin and nonmagnetic feature; Application operability and construction quality is good, little on the damage of original structure, the artistic characteristic that can not change original structure little on the impact of original structure headroom, the inhibition of fracture is better while improving bearing capacity.Therefore, the reinforcing that the composite material reinforced method of FRP is widely used in the structural element such as beam, plate, post is pasted.But FRP also has following weakness: the intensity of FRP is very high, and modulus of elasticity is relatively low, and when making full use of its intensity, FRP needs suitable distortion, for rigidity also require reinforce structure be quite inapplicable; Refractoriness and the resistance to elevated temperatures of pasting FRP material epoxy resin used are poor, and running into fire etc. affects larger on strenthening member stress performance; Strenthening member ductility is not enough, can cause the brittle fracture of carbon fiber, thus cause the brittle fracture of structure when the deformation of member is excessive, for needing moderate finite deformation or concerning the higher structure of shockproof requirements, this point is very disadvantageous; The shearing that epoxy resin layer transmits is limited, and shear strain constantly increases, and the shearing strain rear interface that oversteps the extreme limit stripping damage will occur, and the intensity of FRP cannot be fully used; Meanwhile, connecting portion also can become the weak link of whole component.Because structure generation continuous collapse is usually due to vertical supporting member, inefficacy as post etc. causes, conventional stickup FRP is material reinforced cannot be passed through post and bear its load passed over that lost efficacy, although carry out anchoring in reinforcement end by U-shaped stickup FRP, the draw knot force after post inefficacy effectively cannot be guaranteed.Meanwhile, structure generation continuous collapse is usually with fire, blast etc., and therefore FRP reinforces and cannot be directly used in progressive collapse-resisting reinforcing.

(2) reinforcement High Performance Mortar reinforces (HPFL)

Reinforcement High Performance Mortar reinforcing technique spreads the length of load bearing material such as steel mesh reinforcement, gauze wire cloth, steel wire mesh at surface of concrete structure; then be anchored on component with expansion bolt; it is made to form entirety and co-operation; finally spread High Performance Mortar as topping, to improve a kind of reinforcement means of structural bearing capacity and durability.High Performance Mortar and this two class of principal rod material of different nature play a different role in reinforcing, and steel mesh reinforcement etc. improve the supporting capacity of structure, and screed plays protection and cementation.With traditional method for strengthening and repairing as compared with steel bonding, sprayed mortar reinforcing technique etc., reinforcement High Performance Mortar reinforcing and repairing concrete structure has obvious technical advantage, be mainly manifested in following several aspect: steel mesh reinforcement etc. can adopt high-strength material, and tensile strength is high; Not easily get rusty after treatment in surface, and good with the adhesion stress of mortar; High Performance Mortar can well be reinforced component and be bonded as an overall co-operation; Can effectively improve be reinforced component bending resistance, shear-carrying capacity and deformability, improve stiffness of structural member; Reinforce surface layer thin (it is thick that back-up coat is generally 15mm ~ 25mm), headroom is not almost affected; The principal rod that this reinforcing technique adopts and inorganic coagulation material and the same performance of steel concrete, same to life-span, be traditional common building material, himself anticorrosion, high temperature resistant, fireproof performance is good; Short construction period, does not need large-scale facility, equipment; Construction interference is little, can implement the construction of ruggedized construction in less space, except dust during concrete surface process needs control, almost noiseless to the normal use of buildings in general; Technology constructing operation is convenient, and under normal construction condition, effective bond area can reach 100% substantially, and construction quality can effectively be ensured; After reinforcing, dead load increases little, and constructional appearance size and dimension changes very little, compared with other reinforcement means, saves a large amount of mechanical stage student contributions pooled to pay for class activities, labour cost and check fee; Widely applicable, the reinforcing and repairing of various structure types (as bridge, building, structure, tunnel, culvert etc.), various planform (as rectangle, circle, curved-surface structure etc.), various structure position (Ru Liang, plate, post, arch, shell etc.) can be widely used in; Maintenance cost is low, and maintenance cost at least reduces more than 1/2 than other reinforcement means, and maintenance cycle significantly extends, thus significantly reduces maintenance cost.But this reinforcing technique also exists following shortcoming: the method by fixing principal rods such as expansion bolt, shearing resistance pins, and need provide shearing resistance adhesion strength, construction comparatively bothers and builds original structure and causes certain damage; Between back-up coat and original structure there is bonding stripping damage in transaction, and the intensity of reinforcement material not easily makes full use of; When the rigidity of structure and Ductility Requirement higher be difficult to meet.Meanwhile, be directly used in progressive collapse-resisting and reinforce the difficulty also needing to overcome traversed node.

(3) steel-bonded reinforcement

Cohesive-Steeled Reinforcement Technique essence is a kind of external prestressing tendon, by improving the quantity of reinforcement of former component, thus the ability of the aspects such as the rigidity of corresponding raising structural element, tension, resistance to compression, bending resistance and shearing resistance.Steel-bonded reinforcement does not increase the load of component and structure substantially, does not change intrinsic structural system and stress form, does not affect the use clear space of bridge, does not affect the outward appearance of component; Bonding adhesive firm time is fast, short construction period; Bonding adhesive intensity, higher than concrete body intensity, can make reinforcing body and former component form a good entirety and co-operation, stressed comparatively even, the less stress concentration phenomenon that produces in concrete; Consolidation effect is remarkable, and technique is simple, and do not need special installation, required labour is few, is easy to operation.But the anchorage problem of steel-bonded reinforcement light plate is more outstanding, the bond damage phenomenons such as steel plate must not come unstuck before breaking must be ensured, require that steel plate must be greater than the tensile capacity of steel plate at the bonding shear resistance capacity of anchorage zone; In addition, the requirement for anticorrosion for steel plate is high, and long-time maintenance cost is slightly high.Reinforce for progressive collapse-resisting and must overcome high temperature and a fireproof difficult problem equally.

(4) increasing section is reinforced

Increasing section reinforcing technique is the size by increasing soffit or side, increases and joins main muscle, improves effective height and the flexural strength of beam or post, thus improves structural bearing capacity.Be a kind of traditional reinforcement means at China's section-increased method, technique is simple, widely applicable.But the situ wet work operations amount that this method requires is large, curing time is longer, reinforcement makes dead load and dead load moment of flexure increase more, the original concrete strength restriction in bearing capacity pressure zone, and affect structure headroom, there is considerable influence to original structure usage space, the damage of giving a farfetched interpretation that steel bar continuous just cannot be avoided original structure will be made simultaneously, make it not be suitable for progressive collapse-resisting and reinforce.
