[0027] like Figures 1 to 6 As shown, a schematic diagram of an embodiment of an auxiliary steel bar traction device of the present invention includes a traction line 2 for pulling the steel bar 1, and also includes a fixing part 3 and a locking part 4. The fixing part 3 is penetrated to form a reinforcement hole 31. The steel bar 1 can be inserted into the reinforcement hole 31 and the locking part 4 is inserted into the reinforcement hole 31 to fix it. The traction line 2 is connected to the fixing part 3 to drive the steel bar 1 to move.

[0028] This embodiment can improve the connection quality between the steel bar 1 and the traction line 2, and play a better traction and guiding role in the movement of the steel bar 1, making it easier for the steel bar 1 to pass through the gaps in the steel bar truss. It can be applied to traction lines 2 made of various materials such as nylon and fine steel wire, and has a wide applicability. The traction line 2 can be used to locate the movement route of the steel bar 1, and the steel bar 1 can be quickly inserted into the gaps between the upper chord steel bar 6 / lower chord steel bar 7 and the web steel bar 8 of the steel bar truss, and the steel bar 1 can be accurately pushed forward to pass through the corresponding layers of the adjacent trusses one by one. By locating the movement route of the steel bar 1 during the insertion process, the impact of the steel bar end on the lower chord steel bar 7 and the web steel bar 8 is reduced, construction efficiency is improved, personnel operation is facilitated, and labor costs are reduced. In addition, the structure is simple, and different personnel can quickly fix the steel bar 1 and the traction line 2, avoiding the hidden danger of the fixing effect being affected by differences in personnel installation techniques. The fixing effect can also be improved, and the hidden danger of the steel bar 1 being separated from the traction line 2 during movement is reduced.

[0029] In this embodiment, the fixing member 3 is fixed to the pulled end of the steel bar 1, and the inner diameter of the through-rebar hole 31 is set to increase along the pulling direction of the steel bar 1. If the steel bar 1 needs to be inserted into the steel truss from left to right, the fixing member 3 is fixed to the rightmost end of the steel bar 1 and the inner diameter of the through-rebar hole 31 gradually increases from left to right. In this embodiment, there are multiple locking members 4, and multiple locking members 4 can be spliced ​​together to form a shape that matches the through-rebar hole 31 and form a cavity inside to accommodate the steel bar 1. In this embodiment, when the locking member 4 is inserted into the through-rebar hole 31 to fix the steel bar 1, the inner wall surface of the through-rebar hole 31 and the surface of the steel bar 1 are tightly fitted with the corresponding surfaces of the locking member 4 respectively. The locking member 4 that is adapted to the shape and size of the through-rebar hole 31 and the steel bar 1 can improve the clamping effect of the steel bar 1, prevent the steel bar 1 from being separated from the traction line 2 during movement, and improve construction stability. This embodiment can further tighten the steel bar 1 by generating a radial component force when the traction line 2 tightens the fixing part 3 to drive the steel bar 1 to move, thereby solving the problem of poor connection stability, easy falling off or dislocation between the traction line 2 and the steel bar 1, thereby avoiding secondary positioning of the traction line 2 or the need for manual reinforcement in the middle, ensuring the guiding effect on the movement of the steel bar 1, and ensuring construction efficiency and labor costs.

[0030] In this embodiment, an anti-slip layer 41 is provided on the side of the locking member 4 near the rebar 1 to increase friction between the rebar 1 and the locking member 4, thereby improving the grip of the rebar 1. In this embodiment, the anti-slip layer 41 is formed by stripes on the side of the locking member 4 near the rebar 1, making it more suitable for rebar 1 with threaded surfaces. In other embodiments, the anti-slip layer 41 can also be a rubber pad.

[0031] In this embodiment, the reinforcement hole 31 is truncated cone-shaped, and the number of locking members 4 is multiple. The multiple locking members 4 can be spliced ​​together to form a truncated cone shape that matches the reinforcement hole 31 and form a cavity inside to accommodate the steel bar 1. In this embodiment, the truncated cone-shaped clamp formed by the truncated cone-shaped reinforcement hole 31 and the multiple locking members 4 can be used to clamp the steel bar 1 through the radial component force generated when the fixing member 3 is pulled to drive the steel bar 1 to move, thereby achieving rapid and stable traction of the reinforcement, thereby solving the problems of low reinforcement construction efficiency, inconvenient operation, and a large amount of manpower waste. The truncated cone-shaped design structure is simple, easy to process and manufacture, and has a low production cost, and can be widely promoted and applied. In other embodiments, the reinforcement hole 31 can also be set to a trapezoidal shape, a cone, etc., and the locking member 4 can be adaptively adjusted according to the shape of the reinforcement hole 31.

[0032] In this embodiment, the fixing member 3 can be made of a seamless steel pipe to form a sleeve with a truncated cone-shaped reinforcement hole 31 inside. There are two locking members 4, and the symmetrical structure is simple. It can ensure that the locking member 4 is smoothly inserted into the reinforcement hole 31 without setting a slide groove, which is convenient and flexible to operate. The central angle of each locking member 4 is 180°. The two locking members 4 are spliced ​​together to form a cavity with an internal cavity for accommodating the steel bar 1. The two locking members 4 can be combined into a truncated cone shape to be inserted into the reinforcement hole 31 and firmly clamped to the outside of the steel bar 1. The opening method of each locking member 4 for forming the cavity can be made by opening a semicircular groove along the axis of the locking member 4. In other embodiments, the size of the groove can be changed to be used for the traction construction of steel bars 1 of different sizes and specifications. In this embodiment, stripes are processed in the groove of the locking member 4 to increase friction.

[0033] In this embodiment, the fixing member 3 is provided with a traction ring 5 for connecting the traction line 2. The traction ring 5 enables a detachable connection between the fixing member 3 and the traction line 2, which is easy to disassemble and reusable. The detachable connection method also allows the traction line 2 to be replaced with a suitable length according to the construction scenario, which is flexible in use.

[0034] In this embodiment, the traction rings 5 ​​are U-shaped and are arranged in a cross-sectional arrangement. In this embodiment, the traction line 2 can be fixed at the intersection of the multiple traction rings 5, reducing the risk of the traction line 2 deflecting when the traction rings 5 ​​are pulled, thereby improving the quality of the movement path of the positioned rebar 1. In this embodiment, both ends of each traction ring 5 are fixedly connected to the fixing member 3, and the two ends of the traction ring 5 are symmetrically located on opposite sides of the pulled end of the fixing member 3. This embodiment facilitates the operator to accurately locate the intersection of the multiple traction rings 5, enabling rapid installation and improving construction efficiency. It also avoids the risk of different installation techniques affecting the fixing effect, thereby ensuring installation quality. In other embodiments, the fixing member 3 and the traction ring 5 can be rotatably connected according to usage requirements. This rotatable connection facilitates the insertion of the locking member 4 into the rebar insertion hole 31, improving user flexibility. In this embodiment, both ends of the traction ring 5 are connected to the ends of the fixing member 3. In other embodiments, the connection position of the two ends of the traction ring 5 to the fixing member 3 can be adjusted, such as in the middle of the fixing member 3.

[0035] In this embodiment, there are two traction rings 5, and the two traction rings 5 ​​can be arranged perpendicular to each other in a cross shape. The structure is simple and the production cost is low. The intersection of the cross is convenient for locating the installation position of the traction line 2. The installation method is simple, avoiding the influence of differences in installation techniques of personnel on the traction and guiding effect of the steel bar 1, which can ensure construction efficiency and the traction and positioning effect of the steel bar 1.

[0036] In this embodiment, the pulled end of each fixing member 3 is welded to two cross-shaped U-shaped traction rings 5, and the connection is stable. In this embodiment, the ends of the steel bars 1 can be clamped by the two locking members 4 and the fixing member 3, and the steel bars 1 can be pulled into place at one time under the action of the traction line 2. This embodiment has a simple structure, low production cost, is safe and reliable, and has high construction efficiency. By using the cone-shaped reinforcement hole 31 in combination with multiple locking members 4, when the traction line 2 tightens the traction ring 5 to drive the steel bar 1 to move, the radial component force generated can further tighten the steel bar 1, thereby solving the problem of poor connection stability, easy falling off or dislocation between the traction line 2 and the steel bar 1, and avoiding the waste of labor costs caused by secondary positioning of the traction line 2 or manual reinforcement.

[0037] The construction process of this utility model is as follows, including the following construction steps:

[0038] The end of the steel bar 1 is inserted into the through-rebar hole 31 along the direction in which the inner diameter of the through-rebar hole 31 gradually increases. During actual construction, the end of the steel bar 1 is inserted into the through-rebar hole 31 by at least 100 mm, and then the steel bar 1 is fixed in the through-rebar hole 31 by a locking piece 4 of adapted size. In this embodiment, the direction in which the locking piece 4 is inserted into the through-rebar hole 31 is opposite to the direction in which the end of the steel bar 1 is inserted into the through-rebar hole 31, and the direction in which the locking piece 4 is inserted into the through-rebar hole 31 is opposite to the direction in which the steel bar 1 is pulled. After the locking piece 4 is inserted into the through-rebar hole 31, the side of the locking piece 4 close to the steel bar 1 fits tightly with the steel bar 1, that is, the semicircular groove of the locking piece 4 along the axis can fit with the steel bar 1; the side of the locking piece 4 away from the steel bar 1 fits with the inner wall of the fixing piece 3. The traction line 2 is connected to the traction ring 5 to drive the steel bar 1 to move, and the traction line 2 is installed at the intersection where multiple traction rings 5 ​​intersect.

[0039] After completing the positioning and pulling of the steel bar 1, the auxiliary steel bar pulling device can be disassembled for subsequent use.

[0040] The utility model can improve the connection stability between the steel bar 1 and the traction line 2, avoid the hidden danger of different people's installation techniques affecting the fixing effect, improve the positioning quality of the steel bar traction, and thus ensure construction efficiency and labor costs. It has a simple structure, is easy to operate, and can be disassembled and reused.

[0041] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention.
