Description
Technical Field
The utility model relates to a grout sleeve especially relates to a sloping hole formula grout sleeve for steel bar connection.
Background
The assembly type building is a building type which is vigorously developed in recent years in China due to the fact that the construction period is fast, resources are saved, and construction waste is reduced. The connection of steel bars in fabricated structure nodes is key, wherein the connection of grouting sleeves is mostly used, but the common sleeves are difficult to detect the compactness of grouting materials filled in the common sleeves by conventional detection means, such as an ultrasonic method, an impact echo method and the like, and the grouting holes are easy to leak the grouting materials if not plugged in time, so that effective judgment is lacked in the on-site inspection and completion acceptance stages.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model provides a sloping hole type grout sleeve for steel bar connection.
The utility model provides a sloping hole formula grout sleeve for connection of steel reinforcement, including the sleeve body, the lateral wall of sleeve body is connected with the ascending grout outlet and the grout hole of slope, the axis in grout outlet with contained angle between the axis of sleeve body is the acute angle, the axis in grout hole with contained angle between the axis of sleeve body is the acute angle.
As a further improvement, the grout outlet is connected with a grout outlet pipe inclined upwards, and the grout outlet is connected with a grout outlet pipe inclined upwards.
As a further improvement, when the axis of sleeve body is perpendicular to the horizontal plane, the axis homogeneous phase in grout outlet and grout hole sets up for horizontal plane tilt up 45, the axis of grout outlet pipe and grout pipe all is between 30 to 45 to horizontal plane tilt up.
The utility model has the advantages that: through above-mentioned scheme, the circumstances of the closely knit degree of inside grout material is judged to the ascending grout outlet of accessible slope.

Fig. 3 is an engineering schematic view of the grouting sleeve for inclined hole type steel bar connection of the present invention.
Detailed Description
The present invention will be further described with reference to the following description and embodiments.
As shown in fig. 1 to 3, the grouting sleeve for inclined hole type steel bar connection comprises a sleeve body 1, wherein a side wall of the sleeve body 1 is connected with a slurry outlet 11 and a grouting hole 12 which incline upwards, an included angle between an axis of the slurry outlet 11 and an axis of the sleeve body 1 is an acute angle, and an included angle between an axis of the grouting hole 12 and an axis of the sleeve body 1 is an acute angle.
As shown in fig. 1 to 3, the grout outlet 11 is connected with the grout outlet 2 inclined upward, and the grout outlet 12 is connected with the grout outlet 3 inclined upward.
As shown in fig. 1 to 3, when the axis of the sleeve body 1 is perpendicular to the horizontal plane, the axes of the grout outlet 11 and the grout inlet 12 are both inclined upward by 45 ° with respect to the horizontal plane, and the axes of the grout outlet 2 and the grout outlet 3 are both inclined upward by 30 ° to 45 ° with respect to the horizontal plane.
As shown in fig. 1 to 3, the sleeve body 1 is used for connecting the upper structure 4 and the lower structure 8, the steel bars 5 pass through the sleeve body 1, the edge sealing material 7 is used for blocking the grouting material 6, and the grouting material 6 is poured through the grouting guide pipe 3 and the grouting hole 12.
The utility model provides a pair of inclined hole formula grout sleeve for connection of steel reinforcement from the grout of 3 departments of grout pipe, 6 grout materials flow through the sleeve inside and get into out thick liquid pipe 2 and accomplish grouting work promptly. Because the grout outlet pipe 2 is communicated with the interior of the sleeve, the filling condition of the grout 6 in the grout outlet pipe 2 can be observed through eyes after the grout outlet pipe is finished, so that the internal compaction condition of the sleeve can be inferred. Due to the gravitational potential energy, if a cavity 9 is formed inside the sleeve, the grouting material 6 in the grout outlet pipe 2 flows back into the sleeve, so that the grouting material 6 in the grout outlet pipe 2 is lost. The upward inclination of the grout holes 12 and the grout pipes 3 helps to block the backflow of the grout 6. If all the internal parts of the slurry outlet guide pipes 2 are lost, the cavity 9 in the sleeve can be judged, the high-efficiency expanding agent can be injected to fill the internal parts of the sleeve, slurry filling is completed, and the cavity can be effectively filled by later expansion of the expanding agent.
The utility model provides a pair of inclined hole formula grout sleeve for steel bar connection adopts the effectual problem of having solved its inside closely knit degree and being difficult for detecting of form that combines out two holes and two pipe tilt up.
The utility model provides a pair of inclined hole formula grout sleeve for connection of steel reinforcement has following advantage:
1. the detection in the slurry outlet conduit 2 is clear and considerable, which is beneficial to making judgment.
2. The detection cost is lower, the efficiency is high, and the influence of the building form is small.
3. The upward inclination of the grout holes 12 and the grout pipes 3 helps to block the backflow of the grout 6.
4. The slurry is supplemented in a mode of injecting the efficient expanding agent, so that the inner cavity of the sleeve can be effectively filled.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
