Description
Technical field
The utility model relates to a kind of existing frame strengthening structure supporting with border steel of setting up, and belongs to seismic hardening technical field.
Background technology
Reinforced concrete structure is current most popular form of structure.Office building, house, market of a collection of reinforced concrete structure etc. have been built in China.Because the design in house is improper, working service is improper, the reasons such as natural calamity such as build guality and earthquake, just there is such or such problem in many houses, some problem remains serious, crisis structural safety.Or because new instructions for use, house need to change purposes or add layer etc.All need original structure to reinforce.
At present, the reinforcement means of recommending in standard still take to strengthening of structural element as main, to improving integrally-built anti-seismic performance by improving the strength and ductility of member.For existing framework house, available main reinforcement means has: Enlargement of Section, displacement coagulation local method, outer sticky reinforcement method of steel shapes, stickup fibrous composite method, affixing steel plate reinforcement method etc.There is many disadvantages in these class methods, for example to make newly-increased structure and original structure bonding jointly stressed, it implements generally and can dig original structure, connecting by adhesive, one effect after bonding is difficult to guarantee, cannot carry out off-load to original structure again because of the present circumstance simultaneously, original loadbearing member is forced to accept newly to add surface in the situation that completing main stress deformation, newly adding surface members often stressed hysteresis in the time of earthquake, there is very large deviation in its actual loading and reinforcing design computation model.The structure differing greatly for some actual shock resistances and existing shockproof requirements, if a large amount of members are reinforced one by one, engineering quantity can be very heavy, not only the duration is very long, and very large to finishing persecution, reinforcing and maintenance cost are also very high, and after being difficult to guarantee reinforcing, structure can play useful effect at cooperative bearing under geological process.
Utility model content
In order to overcome prior art deficiency, the utility model proposes a kind of existing frame strengthening structure supporting with border steel of setting up.The utility model is by setting up the anti-dynamometry steel truss of a sealing to existing frame construction, the rod end power of support will be born by frame, can not produce additional internal force by coupled columns, and similar newly-increased one blocks up shear wall, has effectively solved the seismic hardening problem of existing framework.
The technical solution of the utility model is as follows:
A kind of existing frame strengthening structure supporting with border steel of setting up, being embedded in band border steel at the existing framework being surrounded by concrete frame trestle and concrete frame beam supports, described band border steel supports and comprises that section steel edge frame and steel support, X-shaped steel supports and is arranged at shaped steel frame inside, described shaped steel frame outside is welded with peg, described concrete frame trestle and concrete frame beam inner side are embedded with rear anchor bolt, described peg and rear anchor bolt embed junction and are provided with spiral reinforcement, and have been pressed into non-shrink mortar.
Its reinforcement means specifically comprises the steps:
Step 1: first remove and intend reinforcing roof, podium, the aileron in existing framework, retain concrete frame trestle and concrete frame beam; And remove concrete frame beam and concrete frame trestle crust simultaneously, expose concrete structure;
Step 2: at concrete frame trestle and concrete frame beam drilling on inner side, bury rear anchor bolt underground;
Step 3: make band border steel support, and outside shaped steel frame weld stud, after having welded, carry out antirust, anti-corrosive processing;
Step 4: will be with border steel to support after above-mentioned steps completes and embed in existing framework, and arrange spiral reinforcement at rear anchor bolt and peg junction;
Step 5: by the support of band border steel, anchor bolt, peg and spiral reinforcement supporting and location in step 4, after completing, carry out formwork, and be pressed into non-shrink mortar with parcel peg, rear anchor bolt and spiral reinforcement;
Step 6: after mortar reaches requirement of strength, stripping, carries out outward appearance processing.
Wherein:
Described rear anchor bolt is anchor bolt after binding type.
Described rear anchor bolt diameter d
a=20mm, anchorage length l
1>=6d
a.
Described peg is divided into two and arranges and put, line-spacing g >=60mm; Described rear anchor bolt is to arrange to put.
Described spiral reinforcement diameter is 6mm.
Described band border steel is supported for H formed steel construction.
Beneficial effect: adopt and the utility model has the advantages that simple to operately, maintenance effect is reliable, and the supporting member increasing can pass to power on building foundation, and therefore this reinforcement means is relatively applicable to the reinforcing maintenance of whole building.
