Abstract
The utility model discloses variable diameters rigid sleeves, in hollow cylindrical, with upper and lower capping, the cylindrical sleeves outer surface includes the longitudinal floor being angularly distributed, the annular plate of equidistantly distributed and variable diameter enlarged, the cylindrical sleeves are divided into the first semicolumn and the second semicolumn, first semicolumn and the second semicircle column symmetry, it is described longitudinal direction floor on be provided with hole, the first semicolumn and the second semicolumn are fixed by bolt.Using variable diameters rigid sleeve; to adapt to the requirement of male structure outside hollow steel bar concrete component; when being centrifuged rotation; rigid sleeve is reinforced using the longitudinal floor and annular plate of rigid sleeve; it is attached by rigid sleeve and centrifugation apparatus, is driven the better centrifugal movement of hollow steel bar concrete component may be implemented; and hollow steel bar concrete component is protected, prolong the service life.
Description
Technical field
The utility model relates to concrete-filled steel tubular hollow structural elements production field, especially a kind of production hollow steel pipe is mixed
The variable diameters rigid sleeve of Xtah Crude Clay structure component.
Background technique
Existing hollow steel bar concrete component or concrete-filled steel tubular hollow component use Steel pipe mould, make to Steel pipe mould
Production production is carried out with centrifugation apparatus, the hollow steel bar concrete or concrete-filled steel tubular hollow outer profile manufactured out are
The cylindrical body of diameter.Steel core concrete column surface in building structure has some attaching plate elements, and outer profile is non-isodiametric
Cylindrical body has some plates and protrudes, and existing production process cannot be met the requirements, and not can be carried out production production.
Utility model content
Utility model aims to solve the deficiencies in the prior art, provide variable diameters rigid sleeve.
In order to achieve the above object, the following technical schemes are provided:
Variable diameters rigid sleeve is in hollow cylindrical, and with capping up and down, the cylindrical sleeves outer surface includes angularly
Longitudinal floor of distribution, the annular plate of equidistantly distributed and variable diameter enlarged, the cylindrical sleeves are divided into the first semicolumn
With the second semicolumn, first semicolumn and the second semicircle column symmetry are provided with hole on the longitudinal direction floor, by bolt by the
One semicolumn and the second semicolumn are fixed, and the diameter of the variable diameter enlarged is greater than the diameter of cylindrical sleeves, pass through variable cross-section
The diameter of end plate increase variable cross-section enlarged.
Preferably, the annular plate and longitudinal floor are perpendicular.
Preferably, the outer diameter of the variable diameter enlarged has annular plate.
Preferably, the single cylindrical sleeves include eight longitudinal floors and 5 annular plates.
The utility model has the following beneficial effects: using variable diameters rigid sleeve, to adapt to outside hollow steel bar concrete component
The requirement of male structure, when being centrifuged rotation, the steel pipe walls stiffness by itself deficiency of hollow steel bar concrete component cannot be set with centrifugation
It is standby to be directly connected to, be driven, rigid sleeve is reinforced using the longitudinal floor and annular plate of rigid sleeve, passes through rigidity
Sleeve and centrifugation apparatus be attached, is driven the better centrifugal movement of hollow steel bar concrete component may be implemented, and protects sky
Heart reinforced concrete member, prolongs the service life.

Concrete meaning in novel.
Variable diameters rigid sleeve as shown in Figure 1 is in hollow cylindrical, with capping 105 up and down, outside the cylindrical sleeves
Surface includes the longitudinal floor 100 being angularly distributed, the annular plate 101 of equidistantly distributed and variable diameter enlarged 102, described
Cylindrical sleeves are divided into the first semicolumn and the second semicolumn as shown in Fig. 2, first semicolumn and the second semicircle column symmetry, institute
It states and is provided with hole 104 on longitudinal floor 100, fixed the first semicolumn and the second semicolumn by bolt, the variable diameter expansion section
Points 102 diameter is greater than the diameter of cylindrical sleeves, passes through the diameter that variable cross-section end plate 103 increases variable diameter enlarged 102.Institute
It states and places concrete-filled steel tubular hollow component 200 in variable diameters rigid sleeve, institute's variable diameter enlarged 102 is for placing hollow steel pipe
The outer male structure of 200 variable diameter of concrete component.
Wherein, the annular plate 101 and longitudinal floor 100 are perpendicular.
Wherein, the outer diameter of the variable diameter enlarged 102 has annular plate 101.
In the course of work, annular plate 101 is directly contacted with centrifugation apparatus, is transmitted the power of centrifugation apparatus, is centrifuged
Movement.
Embodiment one
Single cylindrical sleeves include eight longitudinal floors and 5 annular plates.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model is answered described with power
Subject to the protection scope that benefit requires.
