Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a multifunctional extendable steel bar adjusting wrench. Background Art

[0002] Pile foundation is a structure used to reinforce the land. The pile head is a small part of the pile top, usually with a horseshoe or boat-shaped terrain. This structure can help the pile to be closely connected with the surrounding land, thereby enhancing the overall stability of the land. For some heavy buildings, such as high-rise buildings, bridges, large machinery and equipment, a relatively high foundation bearing capacity is required. In this case, the pile head can also be used to enhance the foundation bearing capacity, thereby ensuring the stability and safety of the building.

[0003] The pile head steel bars will be deformed to varying degrees after being bent and welded. If used directly, the pile's bearing capacity and service life may be reduced. In addition, unstraightened steel bars will affect the overall aesthetics of the building, and iron oxide scale will form on the surface of the bent steel bars, reducing the steel bars' corrosion resistance, which will affect the project, reduce the pile's bearing capacity, and may cause engineering safety issues.

[0004] The existing pile head steel bar straightening methods are mostly carried out by using simple welding tools, or by using existing wrenches to straighten them. However, the straightening effect of the above adjustment methods is poor and not laborious. Utility Model Content

[0012] In general, the utility model has the following advantages:

[0013] The wrench of the utility model utilizes two of the three support shafts to fit with the steel bars, and the remaining support shaft fits with the other side of the steel bars. When the bent steel bars are in the steel bar adjusting portion, the wrench is pulled so that the bent steel bars are subjected to force at three points. From the principle of the lever, it can be known that the wrench of the utility model can easily straighten the bent steel bars.

[0019] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a multifunctional extendable steel bar adjustment wrench provided in this embodiment includes: a steel bar straightening assembly, the steel bar straightening assembly includes a base plate 1 and at least three support shafts 4, at least three support shafts 4 are fixedly connected to the base plate 1, and at least three support shafts 4 are distributed in a triangular shape on the base plate 1 to form a steel bar adjustment portion 6; a handle 2, the handle 2 is fixedly connected to the base plate 1, and an extension rod connection portion is provided on the handle 2. Exemplarily, the three support shafts 4 can be three cylindrical support shafts 4, the support shafts 4 are vertically arranged relative to the plane of the base plate 1, and the three support shafts 4 are preferably distributed in an equilateral triangle, so that the three support shafts 4 arranged in this way can make the steel bars bear better force, thereby facilitating the straightening of the steel bars and being easy to carry. The base plate 1 can be a scrap of steel plate or iron plate at the construction site, the support shafts 4 can be formed by cutting steel bars at the construction site, and the handle can also be formed by cutting steel bars at the construction site.

[0021] The wrench of this embodiment uses two of the three support shafts 4 to fit with the steel bars, and the remaining support shaft 4 fits with the other side of the steel bar. When the bent steel bar is in the steel bar adjustment part 6, the wrench is pulled so that the bent steel bar is subjected to force at three points, and the bent steel bar can be easily straightened.

[0022] In some embodiments, a multifunctional extendable steel bar adjusting wrench also includes an extension rod 10. By setting an extension rod connecting portion at the handle 2, the extension rod connecting portion is connected to the extension rod, which facilitates extending the length of the handle 2, thereby increasing the torque, making it convenient for construction personnel to straighten the steel bars, and the steel bar straightening effect is good.

[0023] like Figure 1-4 As shown, in some embodiments, the extension rod connection portion includes a connection block 3, the connection block 3 is fixedly connected to the handle 2, and the connection block 3 is provided with a connection groove 7 with a polygonal cross section, and the connection groove 7 is used to connect the extension rod 10. By setting the extension rod connection portion of such a structure, it is convenient to lengthen the length of the handle 2, thereby increasing the torque, making it convenient for construction workers to straighten the steel bars, and the steel bar straightening effect is good. Figure 3-4 As shown, for example, the cross-section of the connecting groove 7 can be a regular hexagonal structure, and then a regular hexagonal plug block 9 is set on the extension rod 10, and the plug block 9 is inserted into the connecting groove 7 to connect the two. The connecting groove 7 with a polygonal cross-section is convenient for the extended handle 10 to transmit torque and avoid slipping.
