Embodiment Construction

[0009] The steel bar straight thread connection sleeve of the present invention comprises two parts, an inner steel sleeve 1 and an outer steel sleeve 3 .

[0010] The inner steel sleeve 1 is hollow, and its upper and middle parts are divided into 4 to 12 steel petals 2, and the steel petals 2 are connected with the lower part of the inner steel sleeve 1 as a whole. According to the different diameters of the steel bars to be connected, the number of splits can be different, for example: for steel bars with diameters of 12mm, 14mm and 16mm, it can be divided into 4 petals; for steel bars with diameters of 18mm and 20mm, it can be divided into 6 petals; for steel bars with a diameter of 22mm , 25mm steel bars can be divided into 8 petals; for steel bars with a diameter greater than 25mm, they can be divided into 12 petals. It should be noted that the above splitting method is only an example, and different splitting numbers can also be selected according to actual construction ...

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 [0001] The invention relates to a steel bar mechanical connection joint in construction engineering, in particular to an extruded steel bar straight thread connection sleeve. Background technique [0002] At present, the mechanical connection of steel bars in construction projects is mostly straight thread sleeve connection, and the operation is divided into straight steel bar connection and curved steel bar connection. [0003] The connection of straight steel bars is to tighten the straight thread sleeve on a steel bar with a threaded buckle first with a wrench, and then tighten the other steel bar with a threaded buckle with a wrench to the other end of the sleeve to realize the connection of two steel bars . The disadvantage of this connection method is that it takes more time to connect, and it is very inconvenient to operate when the diameter of the steel bar is large and the length is long. [0004] When connecting rebars with turns, since there are ...
