Description
Technical field
The present invention relates to a kind of ruggedized construction and construction method thereof, particularly a kind of masonry integrative consolidation structure and construction method thereof, belong to aseismatic reinforcement field.
Background technology
At present, China large area exists and the old house of multistory brick-and-concrete structure of building before the eighties still in use, premises ubiquity brick and mortar strength is lower, collar tie beam and constructional column arrange building shortcomings such as not meeting shockproof requirements, building panel mostly is steel concrete prestressed concrete hollow floor, plate end bearing length does not meet the demands, need carry out seismic hardening comprehensive reformation.And conventional reinforcement means such as board wall reinforcing, surface layer are reinforced, all to take certain architectural space, reduce usable floor area, and destroy original water, electricity, the installation of warm pipeline and trend, bring difficulty to the finishing of the reparation after reinforcing, add operating expenses, extend construction period.
Therefore, seek one and do not reduce usable floor area and original building internal pipeline trend, construction is simple, the reinforced masonry wall method and structure form that consolidation effect is good, is continue performance to there is defect house waste heat, reduces the important channel of the wasting of resources.
Summary of the invention
In order to overcome the problems referred to above, the present invention proposes a kind of old masonry integrative consolidation structure and construction method thereof, by arranging overcoat ruggedized construction outside original structure gable, and when overcoat ruggedized construction can not meet shockproof requirements, arrange on the inner longitudinal cross wall surface of original structure and peel off fiber polymer composite layer, when dual seismic guarantee is formed to original structure, while not affecting original structure inner space, add its usable floor area.
To achieve these goals, this invention takes following technical scheme:
A kind of old masonry integrative consolidation structure, the reinforcing jacket structure contour with it is set outward at the gable of original structure and scribbles on the longitudinal cross wall surface, inside of original structure and peel off fiber polymer composite layer, described reinforcing jacket structure is by reinforcement, bottom reinforced column, interlayer reinforced column, reinforce the external reinforcement framework of support and underpinning composition, described underpinning end face and original structure basis either flush, described bottom reinforced column is supported on underpinning, described interlayer reinforced column is supported on bottom reinforced column, described reinforcement is supported on bottom reinforced column or interlayer reinforced column end face, stretching to original structure with original structure junction and propping up the gable lateral surface withstanding on original structure, described reinforcing supports and is arranged between adjacent bottom reinforced column or interlayer reinforced column.
The thickness of described stripping fiber polymer composite layer is no more than 7mm.
Described reinforcement, bottom reinforced column and interlayer reinforced column are reinforced concrete structure, and its sectional dimension is 250x250mm, and strength grade of concrete is C30.
Described reinforcing is supported for herringbone or splayed.
Described reinforcing is supported for reinforced concrete support or bracing members, and its sectional dimension is 150x120mm.
The construction method of described a kind of old masonry integrative consolidation structure, for overcoat is reinforced and the comprehensive strengthening method of jeting fiber polymer composites, comprises the steps:
Step one: according to the reinforcing increase-volume requirement of original structure, confirms the reinforcing width of original structure;
Step 2: the underpinning reinforcing jacket structure in original structure gable arranged outside;
Step 3: the bottom of bottom reinforced column is fixedly connected with underpinning;
Step 4: reinforcement is erected at bottom reinforced column end face, and is fixedly connected with it; Reinforcement props up the lateral surface withstanding on original structure gable near original structure gable end;
Step 5: successively reinforced column and reinforcement between mounting layer, and reinforcing support is set between reinforced column between adjacent layer, until concordant with original structure top;
Step 6: whether the shear-carrying capacity of the inside longitudinal cross wall after checking computations structural strengthening meets shockproof requirements;
Step 7: ungratified wall section surface adopts spraying tool jeting fiber polymer composites to carry out second consolidation;
Step 8: inspection integrative consolidation anti seismic efficiency and security performance.
In described step 7, strengthening structural bearing capacity when jeting fiber polymer composites for ensureing, pasting 1 ~ 2 layer of glass fabric, it pastes flow process is → patch → → patch of sandblasting of sandblasting.
Spraying tool described in described step 7 is shortly cut spray-moulding machine, and its environment for use temperature should control at 25 ± 5 DEG C, and jet thickness is no more than 7mm.
It is described that short to cut spray-moulding machine short glass fiber length be 8 ~ 48mm.
Beneficial effect
Ruggedized construction of the present invention is completely different from traditional masonry bearing capacity thinking, while realizing reliable anti-seismic performance, not only can not because reinforcing the usage space reducing original structure inside, and the usable floor area of original building can be increased, kill two birds with one stone, overcome the defect that existing reinforced masonry wall technology is attended to one thing and lose sight of another.
The present invention treats with a certain discrimination because structural element function is different the reinforcing of masonry structure, overcoat ruggedized construction is adopted to gable, lateral support is provided to original structure, expand the usable floor area of original structure simultaneously, when overcoat ruggedized construction can not meet shockproof requirements, to the longitudinal cross wall of inside, for avoiding taking the interior space, adopt the reinforcing mode at its side sprayed glass fiber polymer composite, form duet, for original structure provides antidetonation guarantee safe against all possibilities, really do not affect the use of original building at all, also change without the need to warming up ancillary facility to the water power of original building inside, construction is simple, consolidation effect is good, saving of work and time, cheap.
