Description
Technical field
The present invention relates to technical field of building construction, and in particular to a kind of drawing grouting inlet pulp hole locking device.
Background technique
It is largely constructed using grouting process in engineering construction and reinforcing, grouting technique directly affects the safety of structure
Property.However, grouting technique and corresponding corollary equipment and unsound grouting quality is caused to be unable to get guarantee at present.Wherein, exist
Every time after the completion of grouting, grouter is extracted into inlet pulp hole, insertion plug by inlet pulp hole block between gap, due to being in the milk very
Dilution, grouting can backflow out of inlet pulp hole, to influence the compaction rate being in the milk in sleeve.
It therefore, can be closely knit for whole grouting caused by being reduced artificially from grouting way a possibility that grouting leakage
Degree is improved.
Summary of the invention
It is an object of the invention to: overcome the above-mentioned problems in the prior art, proposes that one kind is drawing and be in the milk into slurry
Hole locking device avoids extraction grouter and is inserted into the process of plug, to reduce in filling process for closely knit journey of being in the milk
The negative effect of degree.
The purpose of the present invention is achieved through the following technical solutions: a kind of drawing grouting inlet pulp hole locking device,
Including truncated cone-shaped rubber stopper, supporting element, spring and baffle, through-hole, baffle arrangement are in axial direction provided on truncated cone-shaped rubber stopper
In the small side of truncated cone-shaped rubber stopper diameter, supporting element is arranged in the big side of truncated cone-shaped rubber stopper diameter and does not cover the side entirely
Through-hole, spring is located in through-hole, and one end of spring is fixedly connected with baffle, and the other end of spring is fixedly connected with supporting element,
Spring is unanimously in tensional state.
Further, the supporting element is rigid material or is unlikely to deform under spring elongation state.
Further, the supporting element meets at one by several support rods and forms, and the one side of support rod resists rotary table
The big side of shape rubber stopper diameter.
Further, the baffle diameter is greater than the internal diameter of the small side of the truncated cone-shaped rubber stopper diameter.
Further, the rotary table for protruding from the baffle, the big side of the diameter of the rotary table are provided on the baffle
On baffle, and the diameter of the rotary table is less than the internal diameter of the small side of truncated cone-shaped rubber stopper diameter.
Further, one end of the spring is fixedly connected with several support rod intersections, on the other end and baffle
The small side of rotary table diameter is fixedly connected.
Further, it is provided with screw thread on the outside of the truncated cone-shaped rubber stopper, and is connected by screw thread with pulp inlet.
Further, the truncated cone-shaped rubber stopper can be stuffed into grouting connection inlet pulp hole, and fit closely hole wall.
The beneficial effects of the present invention are: the present invention can leak out to avoid caused grouting after grouter is extracted, thus less
Slurries loss in grout sleeve avoids cavity occur in grouting connection.To reduce this process for the negative of grouting connection
Face is rung.The rotary table for protruding from the baffle is provided on the baffle, the big side of the diameter of the rotary table is located on baffle
And the diameter is less than the small side internal diameter of the truncated cone-shaped rubber stopper diameter；Rotary table effectively can prevent baffle inclined when baffle deviates
The range that the small side of truncated cone-shaped rubber stopper diameter can block is removed, to guarantee into the closure after the completion of slurry to inlet pulp hole.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments.
The present invention provides a kind of drawing grouting inlet pulp hole locking device, including supporting element 1, spring 2, truncated cone-shaped rubber stopper
3 and baffle 4, through-hole 5 is in axial direction provided on truncated cone-shaped rubber stopper 3, and it is small that baffle 4 is arranged in 3 diameter of truncated cone-shaped rubber stopper
Side, supporting element 1 are arranged in the big side of 3 diameter of truncated cone-shaped rubber stopper and do not cover the through-hole 5 of the side entirely, and spring 2 is located at logical
In hole 5, one end of spring 2 is fixedly connected with baffle 4, and the other end of spring 2 is fixedly connected with supporting element 1, and spring 2 is constantly in
Tensional state.
The supporting element 1 is rigid material.
The supporting element 1 meets at one by several support rods and forms, and the one side of support rod resists truncated cone-shaped rubber stopper 3
The big side of diameter.
4 diameter of baffle is greater than the diameter of the small side of 3 diameter of truncated cone-shaped rubber stopper, enters less than reinforced bar jointing sleeve
Starch the internal diameter in hole.
One end of the spring 2 is fixedly connected with several support rod intersections, the circle of the other end and truncated cone-shaped baffle 4
It is fixedly connected at the heart.
It is provided with screw thread on the outside of the truncated cone-shaped rubber stopper 3, and is connected by screw thread with pulp inlet.
The truncated cone-shaped rubber stopper 3 can be stuffed into reinforced bar jointing sleeve inlet pulp hole, and fit closely hole wall.
Its application method the following steps are included:
A, pulp inlet locking device of the invention is mounted in reinforced bar jointing sleeve inlet pulp hole, as shown in Figure 5；
B, grouter grout outlet is entangled into reinforced bar jointing sleeve inlet pulp hole, and be in the milk, slurries enter logical across supporting element 1
Hole 5, baffle 4 push baffle 4 to be displaced outwardly under the action of slurry pressure, baffle 4 and 3 smaller diameter side of truncated cone-shaped rubber stopper
End face separation, slurries therefrom overflow, into reinforced bar jointing sleeve inlet pulp hole；
C, grouting flows out to slurry outlet on the upside of reinforced bar jointing sleeve, then it is assumed that grouting finishes；
D, reinforced bar jointing sleeve slurry outlet is closed with plug, and closes grouter；
E, grouter is extracted, grouting is completed, under the action of spring 2, baffle 4 is pulled, and resists truncated cone-shaped rubber again
The end face of 3 smaller diameter sides is filled in, to prevent from having poured into the slurries outflow in reinforced bar jointing sleeve.
The supporting element is arranged in the big side of truncated cone-shaped rubber stopper diameter and does not cover the through-hole of the side entirely, and spring is located at
In through-hole, one end of spring is fixedly connected with baffle, and the other end of spring is fixedly connected with supporting element, and spring is unanimously in stretching
State, grouting when, baffle by the pressure from grouting, spring be stretched post-grouting can enter grout sleeve in；It has been in the milk
Bi Hou, baffle are no longer influenced by the pressure from grouting, spring contraction, and baffle is pressed on the truncated cone-shaped rubber stopper and closes
Inlet pulp hole.
The rotary table for protruding from the baffle is provided on the baffle, the big side of the diameter of the rotary table is located on baffle
And the diameter is less than the small side internal diameter of the truncated cone-shaped rubber stopper diameter；Rotary table effectively can prevent baffle inclined when baffle deviates
The range that the small side of truncated cone-shaped rubber stopper diameter can block is removed, to guarantee into the closure after the completion of slurry to inlet pulp hole.
The present invention, it is reasonable in design, simple, the unnecessary loss of grouting material can be effectively reduced, meanwhile, processing
Simple process, it is low in cost, it can produce in enormous quantities and be promoted the use of in assembled architecture.
