Description
Technical field
The present invention relates to a kind of precast concrete connection construction technical field of prefabricated concrete structure structures,
Transverse steel sleeve grouting connection structure in especially a kind of precast concrete.
Background technology
Prefabricated concrete structure building is built using industrialization technology at present, and main components are prefabricated in the factory life
Production, to scene after these prefabricated concrete components be mounted and connected be integrally formed, such industrial mode of production substantially subtracts
Lack the wet construction amount of construction site, significantly improved speed of application, reduce environmental pollution and supplies consumption, it has also become
The new direction of Building Trade in China development.The bar connecting of prefabricated concrete structure is to influence structure safety-critical, the company of reinforcing bar
Connecing construction technology also has construction quality and installation effectiveness a large effect, ensure quality, improve work efficiency be building industrialization not
The disconnected target pursued.National sector standard《Prefabricated concrete structure technical regulation》JGJ1 is to the reinforcing bar that is used in precast construction
Connection method has carried out pertinent regulations, and middle sleeve grouting connection is the method that key node mainly uses, and can be applied to frame
The bar connecting at section and frame joint is poured after column, shear wall, prefabricated coupling beam horizontal force reinforcing bar.National sector standard JG/
T398《Bar connecting grout sleeve》The related technology requirement of grout sleeve is proposed, related provincial standard alsies specify prefabricated
Grout sleeve connects the position deviation of reinforcing bar, JGJ/T398 standards regulation grout sleeve internal diameter with grout sleeve in concrete component
Minimum value just contains the site error of reinforcing bar and grout sleeve, the grouting set in the prefabricated components (column, wall) vertically installed
As defined in the position satisfaction of cylinder and connection reinforcing bar during dimensional accuracy, it just can guarantee that prefabricated post, the connection main reinforcement of shear wall are smoothly inserted
Enter in the grout sleeve on connected component.
But the horizontal reinforcement that further encounters of assembling frame structure connects, such as prefabricated coupling beam reinforcing bar is poured after in section
Connection, prefabricated post and composite beam it is whole in assembling1Bar connecting in formula frame joint, the bar connecting of this position is with erecting
It is different to the bar connecting of the prefabricated components of installation.Precast beam unit is to hang onto support structure from the top down when mounted
The position of part, it is extremely to control the level and high and low position of two prefabricated components in the range of 2mm~3mm when component is in place
Difficult, in addition also all there are deviations for the position of the connection reinforcing bar in the appearance and size and component of prefabricated components, therefore, a pair of pre-
After component processed is in place, the axis maximum deviation of level docking reinforcing bar would generally be more than the inclined of the connection reinforcing bar of vertical prefabricated components
Difference, the full grout sleeve connection that certain reinforcing bar misalignment of axe can be accommodated using both ends is generally accepted method in the world,
But full grout sleeve connection brings the problem of new again.First, it is to bring joint area concreting difficulty and density
The problem of.Vertically connection grout sleeve minimum diameter size is big as defined in the inner cavity size ratio standard of full grouting chamber sleeve for beam
Some, could preferably meet the needs of horizontal reinforcement connection.And increase barrel bore diameter, sleeve outer diameter must be increased,
After sleeve outer diameter increases, since connector arrange in same section, the gap between grout sleeve arranged in parallel is compared to connected
Gap between reinforcing bar is much smaller, and the full grout sleeve total length designed by the ribbed of China's reinforcing bar is up to 16~20 times of reinforcing bars
Diameter d, if the length of the full grout sleeve of 32mm reinforcing bars is likely to be breached 640mm, between adjacent sleeve in the range of 640mm
Gap it is smaller when, which increases or even causes region concreting difficult, pours rear coagulation
The density hidden danger of soil increases.Secondly, the installation exercise space needed using full grout sleeve is larger, in the cast-in-place area of precast construction
Domain space smaller part, full grout sleeve are difficult to apply.For example, at the prefabricated integral frame node of prefabricated post and composite beam,
Sometimes reinforcing bar intersects intensive, and the pouring quality of concrete, therefore the steel in the region are all cannot be guaranteed using Bar Anchorage connection
Influential point of tendons will be first installed using sleeve grouting connection, when full grout sleeve use of existing integral structure on the vertical muscle of beam at one end,
Sleeve is axially moveable 0.5 times of length sleeve again after component is in place, is set on the connection reinforcing bar of other end component, so at least
The operating space of 1.5 times of length sleeves is needed, if the sectional dimension of pillar is less than 1.5 times of length sleeves, node space is not
Foot, full grout sleeve are just difficult to apply.The reason of similary, the full grout sleeve of integral structure are applied in prefabricated coupling beam horizontal force
When being poured after reinforcing bar section, which is also at least 1.5 times of grout sleeve length, for this purpose, the template and template that use
Engineering, the workload of casting concrete are also bigger, increase site operation cost.These problems can all limit China's assembled
The application of frame structure or technology development.
