Description

Old masonry building aseismicity ruggedized construction
Technical field
The utility model relates to a kind of building reinforce structure, particularly relates to a kind of old masonry building aseismicity ruggedized construction.
Background technology
Along with social production and growth in the living standard, become the weak link of urban lifeline engineering in the face of the level of setting up defences of the wide old building aseismicity transformation of quantity large tracts of land in the city, exist quake-resistant safety hidden danger, need carry out the seismic hardening transformation, at present, mostly existing old building is the masonry structure building, at present, strengthening measure for earthquake resistance for masonry structure is not a lot, and all difficulty is bigger; China is after the earthquake of Tangshan, some old buildings have at that time been carried out the transformation of part, adopted the mode of carrying out seismic hardening in the architectural method of setting up ring beam structure post and reinforcing pull rod of old masonry, this mode, building is normal to be used though do not influence substantially, cost is lower, but this mode can not satisfy the existing antidetonation standard-required of China.
In the prior art, in reinforcing for the masonry building aseismicity, generally adopting maximum to body of wall is to adopt steel concrete board wall or steel mesh reinforcement mortar surface layer to add thick wall body to reinforce; But these two kinds of methods all need the building interior body of wall is reinforced; For the old building of dwelling house class, two kinds of top methods just mean need carry out the resettlement of resident family, also needs to destroy the building interior finishing, exists a large amount of situ wet effects, and the duration is longer, and cost is higher; And because body of wall is thickeied, the building usable floor area also is subjected to the influence of certain degree, therefore to the reinforcing of old dwelling house, is badly in need of having new Shockproof reinforcing method.
Precast construction is higher as a kind of industrialization degree, the technology of Green civilization, existing more use in new construction, and along with the raising of the construction work level of production, the change of the mode of production, the range of application of precast construction can be come wide approximately more.But in the stabilization works of brick mix structure,, brick wall narrow and small owing to working face with newly add reasons such as being connected difficulty, prefabricated panel hoisting and locating difficulty between prefabricated panel, not seeing at present has application.If can solve above-mentioned difficulties, prefabricating technique is introduced in the brick mix structure stabilization works, bring technical significant improvement then can for the brick mix structure stabilization works.
The utility model content
For solving the difficult problem that Hollow Block Masonry Structure Anti-seismic is reinforced, promote technological progress, the utility model proposes a kind of old masonry building aseismicity ruggedized construction, the jacket structure that prefabricated panel is formed is set up in vertical wall both sides outside old masonry building, and jacket structure decorateeed into balcony, and straining beam is set on the roof top of both sides overcoat is socketed, improved the shock resistance of old dwelling house greatly, do not influence resident family and normally live, and improved resident family's habitat condition.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of old masonry building aseismicity ruggedized construction, in old masonry building both sides the overcoat precast construction is set respectively, vertical wall is connected outside the inboard and old masonry building of overcoat precast construction, the top in described room is provided with the roof straining beam, and both sides overcoat precast construction is fixedly connected as an integral body by the roof straining beam.
Described both sides overcoat precast construction, include newly-increased vertical wallboard, newly-increased cross wall plate, newly-increased floor and roof straining beam, the arranged outside of the outer vertical wall of pairing old masonry building has with increasing newly of the outer vertical wall Joint of old masonry building and indulges wallboard in the end of old masonry building cross wall, described newly-increased cross wall panel edges and newly-increased vertical panel edges and the outer vertical wall Joint of old masonry building, the two ends of described newly-increased floor fix with the newly-increased cross wall plate that is positioned at both sides respectively, and the medial surface of newly-increased floor is connected with old masonry external wall.
Described roof straining beam can determine that the number of roof straining beam is more than two or two according to the length of old masonry building.
Described both sides overcoat precast construction also includes newly-increased exterior wall, and described newly-increased exterior wall is connected with the outside end face of newly-increased cross wall plate and newly-increased floor respectively.
Described newly-increased exterior wall is precast rc slab or window.
The old masonry building aseismicity of the utility model ruggedized construction, at first will be by old masonry building being exposed balcony and overhanging member is cleared up, remove old masonry building external paint layer and local weathering part, and old masonry building carried out jointing again, feeds seam, require to dig and the body of wall bar planting according to reinforcing to there being the position to carry out the body of wall pin key; Newly-increased vertical wallboard hoisting and locating welding; Newly-increased cross wall plate hoisting and locating welding, newly-increased floor lifting; Newly-increased indulging between wall and the outer vertical wall of old masonry building connects through concreting, and two layers increase vertical wallboard, newly-increased cross wall plate, newly-increased floor hoisting and locating welding newly, and one deck increases the part ater-casting concreting of vertical wallboard newly; Repeat above-mentioned construction up to top layer; Roof straining beam construction; To the end during the room, water constructional column and collar tie beam concreting after perfusion of grouting material and the reservation between newly-increased vertical wallboard and the outer vertical wall of old masonry building.By the seismic hardening that the old masonry of the technical program is built, be that old masonry building forms integral body by binding material and footing, resist external geological process jointly by collaborative work to each other, form good seismic hardening system.
Beneficial effect after the employing technique scheme is: by ruggedized construction of the present utility model, anti-seismic performance is reliable, satisfied the urban planning requirement, during strengthening construction, can accomplish that resident family does not move, construction is not registered one's residence, member is processed in prefabrication practice, on-site construction time is very short, the wet trade amount is little, and the construction formwork consumption is few, and the job site operating noise is low, overall cost is lower, and ingenious the combining of target with old building aseismicity reinforcing target and service condition improvement increased usable floor area, particularly some city Lao Lou, pass through strengthening reconstruction, increased the washroom or/and the kitchen or/and balcony has improved the quality of life of resident family, the technical solution of the utility model can be widely used in the seismic hardening of existing masonry building.
