Description

Technical Field

[0001] The utility model relates to the field of municipal engineering, in particular to an auxiliary device for facilitating the bending of stirrups. Background Art

[0002] In the prior art, a hook is usually bent at about 135° before the stirrups are installed, and then the stirrups are tied.

[0003] However, if the stirrups are pre-bent into 135° hooks in advance and tied after the main reinforcement is completed, the density of the stirrups will increase after the main reinforcement is completed. The installation of the stirrups will be affected by the main reinforcement. Pre-bending 135° in advance will make the stirrups more difficult to install due to interference from other stirrups, greatly increasing construction time and labor costs.

[0004] If the stirrups are bent to 135° after the main reinforcement and stirrups are installed, the difficulty of bending the stirrups into 135° hooks will be greatly increased due to the limitations of construction conditions. Therefore, the more popular way now is to pre-bend the stirrups to 90° after the main reinforcement is completed, then tie the stirrups, and finally bend the tied 90° stirrups into 135° hooks. However, although pre-bending the stirrups to 90° has little effect on the construction, the 90° stirrups still need to be bent to 135° later, and there is still no good way to do this step. Although bending 90° stirrups to 135° is easier than bending straight stirrups to 135°, there is still a problem of excessive time and labor costs. Summary of the invention

[0005] In order to solve the above technical problems, the utility model provides an auxiliary device for facilitating bending of stirrups, comprising:

[0006] An auxiliary device for facilitating bending of stirrups, characterized by comprising:

[0007] A handle, one end of which is provided with a fixing portion for accommodating stirrups, so that the stirrups can be inserted into the fixing portion through the fixing portion, and then the stirrups can be bent into 135° conveniently and labor-savingly by raising or lowering the handle according to the corresponding angle.

[0008] Furthermore, the fixing portion is a cylinder so that the stirrups are confined in the fixing portion.

[0009] Furthermore, the inventors have actually tested that the cylinder has a length of 3.5-5 cm and has a better effect.

[0010] Furthermore, the fixing part is a fixing block with a hole in the middle, there are at least two fixing blocks, the fixing block is fixedly connected to one end of the handle, and the distance between the fixing blocks is 3-5 cm.

[0011] Preferably, after actual testing by the inventor, when the fixing blocks are nuts, the best effect is achieved when the distance between the fixing blocks is 4 cm.

[0012] Furthermore, in order to avoid the displacement of the stirrups, a guide groove is provided on the handle along the direction of the fixing part. Although the steel bar will not be offset under normal circumstances, if the opening of the fixing part is larger than the diameter of the stirrup, the greater the difference between the two, the greater the probability of the stirrups being offset. Although this problem will not occur if the fixing part is manufactured according to the strict size of the stirrups, in actual use, in order to save costs, nuts with a size similar to that of the stirrups are often used as the fixing part. Therefore, the size of the threaded hole in the nut is often larger than the standard size. If the user is not skilled, the probability of the stirrups being offset is still relatively large. Therefore, two steel bars can be welded on the handle along the direction of the fixing part to form a guide groove to further prevent the problem of stirrup displacement for unskilled staff using the device. Beneficial Effects

[0013] 1. By using this application, there is no need to pre-bend the stirrups to 90°. Instead, after the stirrups are installed, use this tool to uniformly bend the stirrups to 135°, which can not only greatly improve the efficiency of stirrup tying, but also save a lot of time and labor costs.

[0014] 2. The present application is simple and compact, so that it can adapt to the complex environment of on-site bending of stirrups. The stirrup bending tool is used to adjust the stirrups. Compared with the traditional method, it avoids the inconvenience of stirrup installation caused by bending first, and the dilemma of bending later, which makes the operation space complex and the space small, making it difficult to implement the stirrup bending process, resulting in a lot of time and labor costs. In addition, it is safer than traditional manual bending, and can reduce the contact and scratching between the body and the steel bars. It can not only reduce personal injury, but also improve the overall steel bar binding quality. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0020] Embodiment 1: An auxiliary device for facilitating bending of stirrups, comprising:

[0021] An auxiliary device for facilitating bending of stirrups, characterized by comprising:

[0022] A handle 1 is provided at one end of the handle 1 with a fixing portion 2 for accommodating stirrups, the fixing portion 2 is a fixing block with a hole in the middle, there are at least two fixing blocks, the fixing block is fixedly connected to one end of the handle 1, the distance between the fixing blocks is 4 cm, the fixing block is a nut, so that the stirrups can be inserted into the fixing portion 2 through the fixing portion 2, and then the handle 1 can be raised or lowered at the corresponding angle to conveniently and labor-savingly bend the stirrups to 135°.

[0023] In addition, as other options, the utility model also discloses the following technical solutions based on the above embodiments;

[0024] 1. The fixing part 2 is a cylinder with a length of 3.5-5 cm, so as to confine the stirrup in the fixing part 2.

[0025] 2. In order to avoid the displacement of stirrups, a guide groove is provided on the handle 1 along the direction of the fixing part 2. Although the steel bar will not be offset under normal circumstances, if the opening of the fixing part 2 is larger than the diameter of the stirrup, the greater the difference between the two, the greater the probability of the stirrup being offset. Although this problem will not occur if the fixing part 2 is manufactured according to the size of the stirrup, in actual use, in order to save costs, a nut similar to the size of the stirrup is often used as the fixing part 2. Therefore, the size of the threaded hole in the nut is often larger than the standard size. If the user is not skilled, the probability of the stirrup being offset is still relatively large. Therefore, two steel bars can be welded on the handle 1 along the direction of the fixing part 2 to form a guide groove to further prevent the problem of stirrup offset for unskilled staff using the device.

[0026] The preparation method is as follows;

[0027] 1. Required materials: A 2cm diameter threaded steel bar is used as the handle 1, and a pair of nuts with a height of 0.4m and a diameter of 0.14cm are used as the fixing part 2.

[0028] 2. Weld the nut to the threaded steel bar. The first nut is welded to the top of the threaded steel bar using J442 welding rod.

[0029] 3. The second nut is 4 cm away from the first nut and is also welded to the rebar using the J442 welding rod.

[0030] 4. According to the spacing of the steel bar skeleton, cut the handle 1 into corresponding sizes to facilitate the bending of the stirrups.

[0031] The key to this simple tool lies in the strength of the connection between the nut and the threaded steel bar, which must be ensured to be able to withstand sufficient tension.

[0032] Here’s how to use it:

[0033] After the stirrups are tied and bent, use this tool to put the stirrups into the two nuts, and then raise or lower the handle 1 according to the corresponding angle to bend the stirrups to 135 degrees, so as to complete the stirrup bending process.

[0034] The above description is only a specific implementation method of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present utility model, which should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
