Technical Field

[0001] The invention relates to the technical field of steel bar binding, in particular to a steel bar binding method for a plain concrete beam column. Background Art

[0002] In the construction of exposed concrete structures, especially the binding of beam and column reinforcement, it is a job with extremely high technical requirements. The correct binding of reinforcement is not only related to the safety of the structure, but also directly affects the appearance quality of the concrete. However, in the construction process of beams and columns, especially the binding construction of corbel columns, there are some technical difficulties.

[0003] Firstly, the structure of the corbel column is complex, and the steel bar binding requires precise measurement of the spacing between each corbel. This process requires a lot of manual operation and is inefficient. Secondly, during the binding process, due to the lack of supporting structure, the construction workers also need to support the corbels, which not only increases the difficulty of construction, but also affects the quality of the binding.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-5 An embodiment of the present invention discloses a method for binding steel bars for a plain concrete beam and column, which is used to realize the convenience of positioning the binding of the hamstring 3 to improve the application in the construction of complex beams and columns. The specific binding method comprises the following steps:

[0030] S1, fix four main longitudinal bars 1 distributed in a matrix, and set a plurality of stirrups 2 on the outside of the four main longitudinal bars 1, and fix the stirrups 2 on the main longitudinal bars 1 by tying wires;

[0031] S2, installing the frame 4 according to the height of the beef tendon 3 to be installed, and the frame 4 is connected and fixed to the main longitudinal reinforcement 1 through the connecting assembly 5;

[0032] S3, adjusting the positions of the plurality of clamping members 6 so as to satisfy the placement spacing between two adjacent tendons 3, and placing the plurality of tendons 3 on the clamping members 6 in sequence for positioning;

[0033] S4, the corbel stirrups 7 are sleeved on the outside of the plurality of corbels 3 and fixed by tying wires. After the fixing is completed, the connection assembly 5 is disassembled and the frame 4 is taken out.

[0034] That is to say, in the present invention, the frame 4 is used to support and position a plurality of beef tendons 3, so as to improve the convenience of tying the beef tendons 3.

[0035] In some embodiments, the frame 4 in the present invention includes two rod bodies 41, and an adjusting component 42 is arranged between the two rod bodies 41, and the adjusting component 42 is used to adjust the distance between the two rod bodies 41 to meet the installation adaptation of the connecting component 5 and the distance adjustment between the main longitudinal reinforcements 1 on both sides, wherein bending rods 43 are inserted at both ends of the rod body 41, and a locking member for locking the bending rod 43 is arranged on the rod body 41.

[0036] Specifically, the locking member described in this embodiment is preferably configured as a bolt, and the bolt is threadedly connected to the outer side of the rod body 41 for fixing the telescopic length of the bending rod 43, that is, the distance between the two rod bodies 41 in this embodiment is adjustable to adapt to the distance between the main longitudinal reinforcements 1 on both sides. Secondly, the position of the bending rods 43 on both sides can be adjusted to adjust the width of the support, thereby meeting the support requirements of beef tendons 3 of different lengths, and has a wide range of applications.

[0037] As a preferred embodiment, the adjusting component 42 in this embodiment includes a first screw rod 421 fixed on the inner side of the rod body 41, and a sleeve 422 is connected with a nut between the ends of the two first screw rods 421, that is, in this embodiment, the sleeve 422 is rotated to drive the two first screw rods 421 to move relative to each other, and a basket bolt structure is formed between the sleeve 422 and the two first screw rods 421, which is a prior art and will not be described in detail here.

[0038] On the basis of the above embodiment, in this embodiment, a ring 44 is further fixed on the bending rod 43 of the two rod bodies 41, and a guide rod 45 is fixedly installed in one of the rings 44. The guide rod 45 is slidably connected to the ring 44 on the other side, and the clamping part 6 is slidably connected to the outside of the guide rod 45.

[0039] Specifically, the guide rod 45 described in this embodiment is in a U-shaped structure, and one end thereof is bent and slidably connected to a ring 44 on one side. This sliding connection is adopted to adjust the distance between the two rod bodies 41. In addition, the clamping member 6 slides above the guide rod 45.

[0040] Furthermore, the upper and lower ends of the clamping member 6 in this embodiment are provided with V-shaped openings 61, and the clamping member 6 is tilted and slid on the outside of the guide rod 45. Preferably, the clamping member 6 in this embodiment is tilted at forty-five degrees, and the V-shaped openings 61 at both ends are respectively clamped on the two bent parts of the beef tendon 3, so that the corner positioning of the beef tendon 3 can be achieved, and the vertical connection of the beef tendon 3 can be maintained, so as to improve the positioning accuracy of subsequent binding.

[0041] In some embodiments, the cross-section of the guide rod 45 in the present invention is a polygonal structure, and the clamping member 6 is fixed to the guide rod 45 by a locking member 46. That is to say, in the present invention, the position of each clamping member 6 can be adjusted by the spacing of the beef tendons 3 to be installed. Of course, in order to intuitively observe the adjustment width, a scale mark can also be set on the outer side of the guide rod 45 in this embodiment to cause the moving distance.

[0042] On the basis of the above-mentioned embodiment, the locking member 46 in this embodiment is a hexagon socket bolt threadedly connected to the clamping member 6, and the end of the hexagon socket bolt abuts against the outer side of the guide rod 45, that is, when the clamping member 6 slides to the required position, the position of the clamping member 6 can be locked and fixed by locking the above-mentioned hexagon socket bolt.

[0043] In some embodiments, the connection assembly 5 of the present invention includes a shaft rod 51 fixed at the bottom of the rod body 41 , and a locking hoop 52 is rotatably connected to the outer side of the shaft rod 51 .

[0044] In addition, in order to fix the locking hoop 52 , in this embodiment, a second screw 53 is rotatably connected to one end of the locking hoop 52 , and a notch 54 is opened at the other end. The second screw 53 rotates into the notch 54 and is locked by a nut 55 .

[0045] Preferably, in this embodiment, a stopper 56 is bent on the other end of the locking hoop 52 , and the nut 55 is stopped on the inner side of the stopper 56 .

[0046] That is, during the initial installation, the locking hoops 52 on both sides are first sleeved on the outside of the main longitudinal reinforcement 1 on both sides. At this time, the above-mentioned sleeve 422 can be rotated to drive the rod bodies 41 on both sides to move relative to each other until the locking hoops 52 and the main longitudinal reinforcement 1 are tightened with each other. Thereafter, the above-mentioned second screw 53 is rotated to make the second screw 53 rotate into the notch 54. At this time, the nut 55 is rotated, and the clamping force generated by the nut 55 is used to further clamp the locking hoop 52 on the outside of the main longitudinal reinforcement 1 to complete the fixation of the frame 4. It should be noted that the locking hoops 52 on both sides of the present embodiment maintain a horizontal position during installation to ensure the accuracy of the subsequent installation position of the beef tendon 3.

[0047] In summary, the present invention adopts the design of the connecting component 5 to fix the frame 4 on the main longitudinal reinforcement 1, and supports and positions the multiple corbels 3 through the multiple clamping parts 6 on the frame 4, which can effectively improve the installation efficiency of the corbels 3 and reduce the measurement work during the installation of the corbels 3. It ensures that after the corbel stirrups are tied, the multiple corbels 3 are at a predetermined spacing and a predetermined height, thereby improving the molding quality of the subsequent corbel columns. The tying method of the present invention has strong applicability and can be widely used in the construction technology of complex frame beams and columns of large industrial buildings.
