Abstract
The present invention relates to a double tile screw thread steel connecting sleeve cylinder, particularly to a connecting sleeve of a screw thread steel for buildings. The present invention is composed of an outer sleeve (1), a left tile (2) and a right tile (3), wherein the tile-shaped left tile (2) and the tile-shaped right tile (3) are buckled to form an outer cone sleeve shape and are inserted in a cone hole (1-1) of the outer sleeve (1). The surfaces of inner holes of the left tile (2) and the right tile (3) are provided with ditch grooves (4). When the present invention is used, the left tile and the right tile are sheathed on end heads of two butted screw thread steels, so convex ribs on outer circle surfaces of the screw thread steels are matched with the ditch grooves (4) of the surfaces of the inner holes of the left tile and the right tile. In outer sleeve (1), the small ends of an outer cone sleeve formed from the left tile and the right tile are sheathed on the left tile and the right tile, and the outer sleeve is hammered by hand along the axial direction until the outer sleeve is locked. Because component parts of the sleeve cylinder of the present invention are very little, and processing is also very simple, manufacturing cost is extremely low, and field installation is also very convenient. The present invention has the advantages of reasonable design, simple structure and larger popularization value.
Description
Technical field:
The present invention relates to a kind of adapter sleeve of screw-thread steel for building.
Background technology:
At present in the job site of building, when preparing to be poured into the screw-thread steel that goes in the cement and need dock, generally adopt methods such as welding, binding turns, cold extrusion, technology is trouble, and what have also needs special equipment.Though also occur some screw shells now, with the end of two screw-thread steels of this sleeve connection, the processing of this sleeve and operation are also complicated.
Summary of the invention:
In order to overcome the complicated defective of existing screw-thread steel joint, provide a kind of simple in structure, the screw-thread steel branch sleeve that manufacturing cost is lower.The present invention is achieved by following proposal: a kind of double tile screw-thread steel branch sleeve, it is made up of overcoat 1, a left side watts 2 and right watt 3, the left side of tile watts 2 and right watt 3 are buckled into the outer cone shell-like and are inserted in the taper hole 1-1 of overcoat 1, and the bore area of a left side watts 2 and right watt 3 has groove 4.The locking angle of overcoat 1, a left side watts 2 and right watt 3 is all 2～7 degree.Branch sleeve of the present invention in use, a left side watt and right watt are enclosed within on the termination of screw-thread steel of two butt joints, fin on the screw-thread steel outer round surface is coincide with the left watt of groove 4 with right watt bore area, then overcoat 1 is enclosed within on a left side watt and right watt by the small end of a left side watt and right watt formed external conical sleeve, and beat overcoat till locking with hand hammer vertically, whole erection operating process so far finishes.Overcoat and a left side of using in pairs watt and right watt of circular cone that has formed self-locking connect, and the fin on the screw-thread steel outer round surface is stuck in the groove 4, has guaranteed the reliabilities of two screw-thread steel connections.Through being carried out tension test, the screw-thread steel that is connected by double tile screw-thread steel branch sleeve proves that branch sleeve of the present invention connects the tensile strength that tensile strength is not less than mother metal.Because sleeve component part of the present invention is few, process also very simply, so manufacturing cost is extremely cheap, on-the-spot installation is also very convenient.Builing industry is very big to the consumption of bar splice, and therefore a large amount of building costss is saved in bar splice meeting cheaply.It is reasonable in design, simple in structure and have an advantage of big promotional value that the present invention has.
Description of drawings:
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the left view of Fig. 1.
The specific embodiment:
The specific embodiment one: specify present embodiment below in conjunction with Fig. 1 and Fig. 2.It is made up of overcoat 1, a left side watts 2 and right watt 3, and the left side of tile watts 2 and right watt 3 are buckled into the outer cone shell-like and are inserted in the taper hole 1-1 of overcoat 1, and the bore area on a left side watts 2 and the right side watts 3 has groove 4.Groove 4 is the pits by the fin position punch process one-tenth of the screw-thread steel external surface distribution of corresponding model.The locking angle of overcoat 1, a left side watts 2 and right watt 3 is all 2～7 degree.The angle of wedge of 2～7 degree can play good locking effect less than the angle of friction of material.
The specific embodiment two: specify present embodiment below in conjunction with Fig. 2.The difference of present embodiment and embodiment one is, a left side watts 2 and right watt 3 formed external conical sleeves leave seam 5 and seam 6 at two joints.Seam is set makes lip-deep two the vertical tongues of regular screw threads steel can not influence a left side watt and right watt to be fastened on the screw-thread steel surface, and make present embodiment can adapt to the error of screw-thread steel external diameter to a certain extent.
The specific embodiment three: specify present embodiment below in conjunction with Fig. 1.The difference of present embodiment and embodiment one is, on the inner surface of a left side watts 2 and right watt 3 in the middle of the place along the circumferential direction have annular groove 7, the locking angle of overcoat 1, a left side watts 2 and right watt 3 is preferably 3 degree.After annular groove 7 was set, defectives such as " overlaps " of screw-thread steel end can not influence the use of present embodiment.
Claims (4)
1, a kind of double tile screw-thread steel branch sleeve, it is characterized in that it by overcoat (1), a left side watt (2) and the right side watt (3) form, the left side of tile watt (2) and right watt (3) are buckled into the outer cone shell-like and are inserted in the taper hole (1-1) of overcoat (1), the bore area of a left side watt (2) and right watt (3) has groove (4), and the angle of wedge (α) on overcoat (1), a left side watt (2) and the right side watt (3) is all 2～7 degree.
2, double tile screw-thread steel branch sleeve according to claim 1 is characterized in that a left side watt (2) and right watt (3) formed external conical sleeve leave seam (5 and 6) at two joints.
3, double tile screw-thread steel branch sleeve according to claim 1, it is characterized in that on the inner surface of a left side watt (2) and right watt (3) in the middle of locate along the circumferential direction to have annular groove (7).
4, double tile screw-thread steel branch sleeve according to claim 1, the angle of wedge (α) that it is characterized in that overcoat (1), a left side watt (2) and right watt (3) are 3 degree.
