Abstract
The invention discloses an extruded steel bar straight thread connecting sleeve, which comprises two parts, namely an inner steel sleeve and an outer steel sleeve, wherein the upper part and the middle part of the inner steel sleeve are cut into 4 to 12 steel sections and are hollow inverted truncated cones, and the lower part of the inner steel sleeve is connected into a whole and has an inverted truncated cone shape or a cylindrical shape; screw threads are wholly sleeved on an inner side of the inner steel sleeve and are used for meshing with steel bars; an inner side of the outer steel sleeve is a truncated cone surface which has the same slope as that of the outer side of the middle part of the inner steel sleeve; and the upper half part of the outer side of the outer steel sleeve is a truncated cone, and the lower half part of the outer side of the outer steel sleeve has an inverted truncated cone shape or a cylindrical shape. By the steel bar straight thread connecting sleeve, the steel bars can be rapidly and conveniently connected, the connecting quality is effectively guaranteed, and connecting operation can be performed in a small space.
Description
Technical field
The present invention relates to reinforcing steel bar machinery jointing in a kind of construction work, specifically is squash type reinforced bar straight thread branch sleeve.
Background technology
At present, the mechanical connection of reinforcing bar is that mostly straight screw sleeve connects in the construction work, and its straight reinforcing bar of operation time-division connects and turns reinforcing bar and be connected.
It is earlier straight screw sleeve to be screwed up with a wrench on a reinforcing bar that has overlapped screw thread that straight reinforcing bar connects, and the reinforcing bar that then another root has been overlapped screw thread is tightened with the spanner and the sleeve other end, realizes two reinforcing bars connections.The shortcoming of this method of attachment be connect consuming time more, and big when bar diameter, operate when length is longer very inconvenient.
When turning the reinforcing bar connection; Owing in reinforcing cage, turn reinforcing bar and can't rotate, must adopt positive left-hand thread straight screw sleeve, promptly directly rotational sleeve is realized simultaneously two reinforcing bars being tightened; But this method of attachment occurs one easily tightens a situation of not tightening, so can't guarantee workmanship.
Summary of the invention
The objective of the invention is to overcome disadvantages of background technology, provide a kind of connect efficient and convenient, effectively guarantee the reinforced bar straight thread branch sleeve of quality of connection, and in small space, also can realize the firm connection of reinforcing bar.Steel bushing and outer steel sleeve in technical scheme of the present invention comprises, wherein, said interior steel bushing is a hollow; Its top and middle part cutting are a plurality of steel lobes, and the bottom of said steel lobe and interior steel bushing is connected to integral body, and the outside at said top and middle part is a truncated cone-shaped; The inboard at said top and middle part is the rounding table top, and the outside of said bottom is reverse frustoconic or cylindrical shape, and the inboard of said bottom is a barrel surface; The inboard whole process of steel bushing is with screw thread in said, is used for the interlock reinforcing bar; Said outer steel sleeve is a hollow, and its inboard is elongated to be round table surface, and slope is identical with the slope of the outer middle side part of said interior steel bushing, and outside the first half of said outer steel sleeve is a truncated cone-shaped, and the latter half is reverse frustoconic or cylindrical shape.
Description of drawings
Fig. 1 is an embodiment of the invention front view
Fig. 2 is an embodiment of the invention sectional view
Fig. 3 is an embodiment of the invention phantom drawing
The specific embodiment
Steel bushing 1 and outer steel sleeve 3 two parts in reinforced bar straight thread branch sleeve of the present invention comprises.
The inboard elongated of outer steel sleeve 3 is round table surface, and slope is identical with the slope in the outside, interior steel bushing 1 middle part, and outside the first half of outer steel sleeve 3 is a round platform, and the latter half is reverse frustoconic or cylindrical shape.
During connecting reinforcement; The bottom of steel bushing 1 at first a reinforcing bar being tightened in; In the steel lobe 2 on steel bushing 1 top, then outer steel sleeve 3 is inserted in from the upper end of interior steel bushing 1 in then another root reinforcing bar being inserted in, pushes outer steel sleeve 3 downwards; Make steel lobe 2 inside banding reinforcing bars, reach the reliable purpose of connecting fast of two reinforcing bars.
Adopt reinforced bar straight thread branch sleeve of the present invention to make to turn reinforcing bar and can realize reliable connection, and connection procedure can realize connecting fast through special extrusion tool, thereby increase work efficiency.In addition, in small space, also can operate, the for example connection of vertical reinforcement in the reinforced masonry can be satisfied the needs of different construction conditions.
