Description
Technical Field
The utility model belongs to the technical field of the mounting tool of assembly type structure, specifically a steel sleeve.
Technical Field
Most of the conventional buildings are produced by organizing manpower and material resources on site, and the assembly type building technology is a building mode assembled on site by prefabricated components. The most key connection of prefabricated parts in the fabricated building is the connection of steel bars, and the connection part of the steel bars is also a weak link of the whole member under stress. At present, the connection of the prefabricated steel bars mostly adopts a steel bar sleeve grouting connection technology, the principle is that the steel bars penetrate into the sleeve from openings at two ends through a cast hollow sleeve, the lapping or fusion connection is not needed, and the high-strength micro-expansion structural mortar is filled between the steel bars and the sleeve, so that the continuous connection action of the steel bars is completed. The connection mechanism is mainly characterized in that mortar is subjected to the surrounding action of the sleeve and has the characteristic of micro expansion, so that the positive acting force between the mortar and the reinforcing steel bar and the inner side of the sleeve is enhanced, and the reinforcing steel bar transmits the stress of the reinforcing steel bar by the friction force generated by the positive force and the rough surface. The disadvantages of the connection mode are that the technical requirements on operators are high; otherwise, the strength of the steel bar connection can be weakened by collision during installation.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the not enough of existence among the background art, and a steel sleeve that provides.
The utility model discloses a steel bar sleeve, including the sleeve body, the one end of its sleeve body is equipped with first internal thread hole, the other end is equipped with second internal thread hole, and first barrel extension is being connected to first internal thread hole outer end, and second barrel extension is being connected to second internal thread hole outer end, and the internal diameter of first barrel extension and second barrel extension is not less than the internal diameter that is equipped with first internal thread hole and second internal thread hole.
As the utility model discloses a preferred, the screw thread opposite direction in first internal thread hole and second internal thread hole.
Preferably, the second cylinder extension has two transverse through holes in the inner cylinder.
As the utility model discloses a preferred, the inner wall of first barrel extension and second barrel extension all is equipped with spiral bead.
As the utility model discloses a preferred, be equipped with the hexagon notch on the outer wall at sleeve body middle part.
The utility model discloses a steel sleeve, the result is simple, and simple process easily cutting process is favorable to batch production, and the extensive application of being convenient for satisfies actual demand, and is with low costs, adopts the dual fixed mode of screw socket and encapsulating to the area of contact of encapsulating material is big, and sleeve and encapsulating material form zonulae occludens, greatly increased the anchor bonding strength of the two, form zonulae occludens between encapsulating material and the ribbed steel bar, reach reliable bond anchor strength. The reliability of the joint can be improved, and the construction is convenient. The adopted epoxy type bar-planting adhesive has the characteristics of room-temperature curing, high strength, strong bonding force, good durability and the like, greatly shortens the connection time and accelerates the construction progress.

Detailed Description
The following describes a reinforcing sleeve according to the present invention with reference to fig. 1 and fig. 2.
Example 1
The utility model discloses a steel bar sleeve, including sleeve body 1, its sleeve body 1's one end is equipped with first internal thread hole 2, the other end is equipped with second internal thread hole 3, and first barrel extension 4 is being connected to 2 outer ends in first internal thread hole, and second barrel extension 5 is being connected to 3 outer ends in second internal thread hole, and the internal diameter of first barrel extension 4 and second barrel extension 5 is not less than the internal diameter that is equipped with first internal thread hole 2 and second internal thread hole 3.
Example 2
The utility model discloses a steel bar sleeve, including sleeve body 1, its sleeve body 1's one end is equipped with first internal thread hole 2, the other end is equipped with second internal thread hole 3, and first barrel extension 4 is being connected to 2 outer ends in first internal thread hole, and second barrel extension 5 is being connected to 3 outer ends in second internal thread hole, and the internal diameter of first barrel extension 4 and second barrel extension 5 is not less than the internal diameter that is equipped with first internal thread hole 2 and second internal thread hole 3. The thread directions of the first internal thread hole 2 and the second internal thread hole 3 are opposite, and the butt joint end parts of the first reinforcing steel bar 8 and the second reinforcing steel bar 9 are in butt joint with the first internal thread hole 2 and the second internal thread hole 3 of the sleeve body 1 during use. The first-step spiral connection is realized by rotating the sleeve body 1 or rotating the first reinforcing steel bars 8 and the second reinforcing steel bars 9, and then pouring sizing materials into cavities in the first cylinder extending part 4 and the second cylinder extending part 5. Two horizontal perforating holes 6 on the inner barrel of second barrel extension 5, when first reinforcing bar 8 and the vertical connection of second reinforcing bar 9, the bottom is arranged in to the one end that has perforating hole 6, and the rubber sleeve is being suit on the second reinforcing bar 9 of the lower mouth department of second barrel extension 5, avoids encapsulating material 11 too much to run off, pours encapsulating material 11 to the inner chamber of second barrel extension 5 through one of them perforating hole 6, and other holes carry out the air evacuation. The epoxy type bar-planting adhesive adopted by the potting adhesive has the characteristics of room temperature curing, high strength, strong bonding force, good durability and the like, greatly shortens the connection time and accelerates the construction progress. The inner walls of the first cylinder extension part 4 and the second cylinder extension part 5 are both provided with spiral ribs 7, and the first cylinder extension part 4, the second cylinder extension part 5, the first steel bars 8 and the second steel bars 9 are added. Be equipped with hexagon notch 10 on the outer wall at sleeve body 1 middle part, facilitate the use spanner and rotate sleeve body 1, very big improvement the performance of reinforcing bar hookup, guarantee the quality of assembly type structure. The problems of non-uniformity of stress, stress size, uncertainty of service life and the like of the traditional steel bar sleeve grouting connection technology can be solved, the production efficiency can be improved, and the construction time can be shortened.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
