Abstract
A kind of grout sleeve, including grout sleeve ontology, sleeve body are made of seamless steel pipe, and dent is provided in sleeve pipe outer wall, and inner wall is convex surface.The present invention can suitably reduce sleeve body wall thickness under the premise of meeting sleeve body rigidity, save material.Wall thickness is reduced in the case that outer diameter is identical simultaneously, increases grouting material so that grouting is more closely knit, and reinforcing bar and the adhesive property of sleeve body entirety are stronger.
Description
Technical field
The invention belongs to construction engineering technical fields, and in particular to a kind of grout sleeve.
Background technology
In the prior art, the bar connecting between assembly concrete architectural prefab is needed using sleeve grouting connection,
Two connected reinforcing bars are inserted into metal sleeve and high-performance water cement mortar, water are perfused into the gap between sleeve and reinforcing bar
After cement mortar hardening, mutual build-in is to realize the connection of reinforcing bar between three.Conventional grout sleeve is set on the inner wall of sleeve
The anchoring piece of protrusion is set, conventional means is anchoring piece to be welded on sleeve lining or die sinking anchoring piece is cast as one with casing
The manufacturing process of body, these anchoring pieces is not only complex, but also time-consuming takes material.
Invention content
The problems such as in order to overcome conventional grout sleeve processing complexity, time-consuming expense material, the technical solution adopted in the present invention is：
A kind of grout sleeve, including grout sleeve ontology, sleeve body are made of seamless steel pipe, and dent is provided in sleeve pipe outer wall,
Inner wall is convex surface.The dent in column, 2 is no less than per number of columns along the axial uniformly arrangement of tube wall；The dent is constituted recessed
Trace row no less than 2 row, are symmetrically distributed on sleeve tube wall.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention, can under the premise of meeting sleeve body rigidity
Suitably to reduce sleeve body wall thickness, material is saved.Wall thickness is reduced in the case that outer diameter is identical simultaneously, increases grouting material,
So that grouting is more closely knit, reinforcing bar and the adhesive property of sleeve body entirety are stronger.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the C-C of Fig. 1 of the present invention to sectional view.
Fig. 3 is the structural schematic diagram of grout sleeve processing unit (plant) in the present invention.
Fig. 4 is the A-A of Fig. 3 of the present invention to sectional view.
In figure：1 fixes sleeve, 21 first clamping plates, 22 second clamping plates, 23 indentation plates, 3 terminal pads, 4 connecting plates, 5 hydraulic pressure

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of grout sleeve, including grout sleeve ontology, sleeve body are made of seamless steel pipe, are arranged in sleeve pipe outer wall
It is convex surface to have dent, inner wall.The dent is axially uniformly arranged in column along tube wall, 4 dents of each column；The dent is constituted recessed
No less than 4 groups of trace row, are symmetrically distributed on sleeve tube wall.
Grout sleeve is made by grout sleeve processing unit (plant), and the grout sleeve processing unit (plant) includes fixes sleeve 1, indentation
Mechanism and terminal pad 3, the indentation mechanism include first clamping plate 21, second clamping plate 22 and indentation plate 23；The first clamping plate 21
It being fixed at outside fixes sleeve 1, the indentation plate 23 is fixed on by axis pin in first clamping plate 21, and the one of the indentation plate 23
The intracavitary of fixes sleeve 1 is stretched at end by the slot being arranged in fixes sleeve 1, and the other end of indentation plate 23 passes through axis pin and second
Clamping plate 22 connects, and second clamping plate 22 is hinged by connecting plate 4 with terminal pad 3, and one end of the fixes sleeve is provided with hydraulic cylinder
5, the hydraulic stem 6 that hydraulic cylinder 5 stretches out is connected in terminal pad 3, and the quantity of the indentation mechanism is 4 groups, in every group of indentation mechanism
Indentation plate 23 and the quantity of slot be 4.
The manufacturing process of grout sleeve sleeve：The seamless steel pipe of suitable length is placed in 1 intracavitary of fixes sleeve, starts hydraulic pressure
Cylinder 5, the hydraulic stem 6 of hydraulic cylinder 5, which stretches out, drives indentation mechanism to generate displacement, and indentation plate 23 rotates, and indentation plate 23 is by slitting
Seamless steel pipe is engraved and pressed to dent by the part that slot stretches into 1 intracavitary of fixes sleeve, restores hydraulic cylinder 5, and the retraction of hydraulic stem 6 drives indentation
Reset, you can take out with pitted seamless steel pipe, complete process.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
