Description
Technical field
The present invention relates to a kind of reinforcing bar grouting connector grouting material plugging devices, belong to assembly concrete building field.
Background technique
In prefabricated concrete structure, the installation of the vertical prefabricated components of concrete with connect frequently with grouting connector connect
Connection member vertical reinforcement, common methods have: sleeve grouting connection, slurry anchor overlap joint connection etc., these methods are all below connector
Slurry-feeding hole injection grouting material siccative add water mix uniformly made of be in the milk slurry body, be in the milk slurry body it is upward from connector lower part
Air is released in flowing, when the top slurry outlet of connector outflow grouting slurry body, shows to have been filled with grouting slurry body in connector,
After slurry body of being in the milk solidifies and reaches design strength, i.e., the reinforcing bar at connector both ends of being in the milk is linked together.
When prefabricated concrete structure building grouting connection construction, grout hole, the slurry outlet for the connector that is in the milk mainly use circle
Taper rubber plug blocks, and the grout hole of reinforcing bar grouting connector or slurry outlet are usually with forming plastic pipe in prefabricated components, due to plastics
Bore size has differences, and the ability that tube wall receiving concrete members pour pressure is different, sometimes same prefabricated components table
Face slurry outlet aperture or shape are not consistent, and the grout hole of the component product of different component factory, slurry outlet are easier to deposit
In difference, live grouting operation personnel face various prefabricated components, can not check the size of slurry outlet one by one, only be in the milk
When seeing that grouting slurry body is flowed out from component surface slurry outlet when construction, good outflow slurry is just blocked as early as possible using the rubber plug got ready
Duct.The frictional force of closure rubber plug and hole wall just can guarantee reliable sealing, rubber plug and hole wall when being greater than the pressure of slurry in hole
Frictional force deficiency just will appear slurry and rubber plug opened and spillage.The closure problem encountered when scene grouting at present is: being in the milk
Slurry outlet top plug, which is blocked up rubber plug, before slurry body outflow to cause grouting material in connector is not full to lack air seal in duct
It falls into, therefore is used by absolute prohibition；And in grouting, when slurry outlet has just had a little grouting slurry body outflow, just blocked with rubber plug
Slurry outlet can make to get lodged in partial air in duct, and such connector is also easy to appear the problem that grouting material is not full in connector.
Only in filling process, grouting slurry body, which is in the form of a column when gushing out from duct, fills in stifled rubber plug, is just avoided that slurry outlet road and connector
The problem of inside suppressing stifled air, but existing grouting slurry body, the slurry can be substantially reduced glue between rubber plug and pulp hole wall at this time
The frictional force of plug and hole wall, therefore the deformation of rubber plug can only be leaned on to improve its pressure to hole wall and increase frictional force, but due to
The geomery deviation of slurry outlet is larger, and the small rubber plug plug in hole, which is not entered, or depth is not in place causes frictional force inadequate, and hole
It is big to be fully inserted into outer diameter deformation with rubber plug and also result in frictional force deficiency not enough, therefore some vertical prefabricated components are in the milk connector
When using connection chamber grouting process, some connector slurry outlets do not flow out slurry also, before the connector slurry outlet that has blocked again
It is opened by the slurry pressure constantly increased in hole and spillage occurs, caused operator to act hurriedly in a messy situation, not only cause the waste of grouting material,
Sometimes operator does not mend slurry to the connector of spillage again for various reasons, and causes in connector that grouting material is not full to be lacked
It falls into.In addition, such as wanting in inspection hole whether grouting material is full using the connector that rubber plug blocks, needs to remove rubber plug and visually observe in hole
Grouting material pulp noodle position, when slurry body of being in the milk can also flow, internal grouting slurry body outflow will be made by removing rubber plug, so
Only grouting slurry body cannot flow and can just remove rubber plug, and being formed can not check in time and judge the full of grouting material in connector duct
The passive situation of degree, it is difficult under being in the milk slurry body in connector caused by discovery is because of a variety of causes when slurry body of being in the milk has mobility
Drop, pulp duct overfall and caused by it is not full, also just can not do necessary benefits for problem in time and starch operation.It is last that there are also one
A deficiency, because grouting connector is mainly disposed to the lower part of component, slurry outlet height is all the lower head in operator, grouting
Situation in slurry outlet is checked after the completion, and rubber plug of not only choosing arduously is taken a lot of work, but also situation is not very in inspection personnel's peep hole
It is convenient, check less than connector may there is a situation where that grouting material is not full.In short, existing rubber plug plugging grouting connector pulp
The technique in hole be difficult to ensure each connector can sealed reliable, easily there is spillage, waste of material, grouting material is to site environment dirt
Dye, and it is difficult to find the not full defect of grouting material in connector in time when grouting material has mobility, grouting in final device to hole
Expect plumpness visual examination it is also inconvenient, these problems be always perplex grouting connection construction, affect construction efficiency and
The quality of connection of structure reinforcing bars connector.
