Description

Stirrup bender for steel bar construction Technical Field The utility model relates to the technical field of processing or treatment of metal wires, in particular to a stirrup bender for steel bar construction. Background In the construction process of the secondary lining steel bars of the tunnel, the traditional method often adopts double-head pre-bending measures for the installation of stirrups. However, this method not only results in the stirrup unloading length overlength, and in the installation, the one end of stirrup is difficult to closely laminate the main muscle moreover, appears the phenomenon of falling easily to influence construction quality and efficiency. On the other hand, if an attempt is made to bend in situ by using a single-head pre-bending method and using a conventional single sleeve, a bending angle of about 90 ° is usually only achieved, and the stirrup cannot be bent to 180 °, or even if the stirrup can be bent, there is a problem that the operation is laborious and inconvenient. Therefore, developing a stirrup bender which is efficient and convenient, can ensure stable installation and save steel at the same time has become an urgent need in the field of construction of secondary lining steel bars of current tunnels. Disclosure of utility model The utility model aims to solve the technical problem of material waste caused by geometric solidification in the existing prefabricated double-elbow stirrup process. In order to achieve the above purpose, according to one aspect of the utility model, a stirrup bender for steel bar construction is provided, which comprises a holding part, a first bending part, a second bending part and a second sleeve end hole, wherein the holding part is a part which is held by an operator, the first bending part is arranged at one end of the holding part, a first sleeve end hole for accommodating the end part of a steel bar is formed in one side of the first bending part, which is far away from the holding part, the second bending part is fixedly arranged at one side of the first bending part, a second sleeve end hole for accommodating the end part of the steel bar is formed in the second bending part, and the second sleeve end hole and the first sleeve end hole face opposite. As the preference of above-mentioned technical scheme, still offer the third sleeve end hole that is used for holding the reinforcing bar tip on the second bending part, the third sleeve end hole is offered and is kept away from one side of second sleeve end hole. Preferably, the third sleeve end hole and the second sleeve end hole are coaxial and communicated, and the aperture of the third sleeve end hole and the aperture of the second sleeve end hole are the same. Preferably, in the above-described aspect, the second bending portion is axially parallel to the first bending portion and is welded and fixed. As a preferable aspect of the above-mentioned technical solution, a side end surface of the second bending portion away from the second sleeve end hole is coplanar with a side end surface of the first bending portion where the first sleeve end hole is provided. Preferably, in the above aspect, the grip portion is integrally formed with the first bending portion. Preferably, in the above technical solution, the first bending portion is disposed coaxially with the holding portion, and the first sleeve end hole extends in an axial direction and penetrates through the holding portion. As a preferable mode of the above technical solution, the grip portion surface is uniformly distributed with an anti-slip layer. Preferably, the holding part is provided with a spiral reinforcing rib. Preferably, in the above technical solution, a double-sided weld is provided in a welding area between the second bending portion and the first bending portion. In summary, the utility model has the following advantages: 1. According to the utility model, through the cooperative design of the double-sleeve structure (the first sleeve end hole and the second sleeve end hole are reversely arranged) and the staged bending process, the three technical pain points of insufficient fitting degree, structure tripping risk and material waste caused by the construction error of the main reinforcement spacing of the traditional prefabricated double-elbow stirrup are effectively solved; 2. Furthermore, the utility model adds the third sleeve end hole to form a three-station structure, and the bending operation difficulty under the slit interference working condition is solved by selectively matching the space limitation of the main rib through the hole position direction; 3. Further, through hole structures formed by the through of the second sleeve end hole and the third sleeve end hole realize full-depth clamping of the stirrup remaining section, and thoroughly avoid the short-end slipping risk; further or other details of the beneficial effects will be discussed in the embodiments.
