JPH0731270U - Angle-compatible pressurizing / depressurizing tool for connecting square steel pipes - Google Patents

Abstract

(57) [Summary] [Purpose] Using a square steel pipe short product with an angle-compatible pressurizing / depressurizing tool for connecting square steel pipes, the labor and time required by the conventional processing method are greatly reduced, and yet Provided is an angle-compatible pressurizing / depressurizing tool for connecting a rectangular steel pipe, which aims to eliminate the trouble of raw material loss that a steel product processor has, by commercializing a rectangular steel pipe for material loss and disposal. [Composition] Angle-corresponding pressure plates (2) and (3) are provided at both ends of the pressure shaft (1), and anti-slip screws (4) are provided at eight positions of the angle-corresponding pressure plates (2) and (3) to apply pressure. Axis (1)
A pressurizing / depressurizing device (5) is provided at the center of the device, and the pressurizing / depressurizing device is pressurized and depressurized by a handle to easily connect and disconnect a plurality of rectangular steel pipes. It is characterized in that a plurality of square steel pipes are unified not only in appearance but also in strength by pressurizing diagonal lines inside the square steel pipes with the pressure plates (2) and (3) corresponding to angles.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an angle-adaptive pressurizing / depressurizing tool in which a pressurizing / depressurizing device is provided with an angle-compatible pressurizing plate. Conventionally, the shortage of square steel pipes, which may cause waste or material loss, has been solved by using the angle-compatible pressurizing / depressing tool for connecting square steel pipes, which eliminates the worries of raw material loss that steel products processors have. Can be done.

[0002]

[Prior art]

 Conventionally, there was a vertical type pressurizing / depressurizing device, and multiple square steel pipes were processed by repeating welding.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (B) Since it is a vertical type, it cannot handle unbalanced loads. (B) Since it is a vertical type, it is very difficult to join multiple square steel pipes inside. (C) Since it is a process that requires repeated welding, it requires a great deal of labor and skill. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for solving the problem]

 Angle-corresponding pressure plates (2) and (3) are provided at both ends of the pressure shaft (1), and anti-slip screws (4) are provided at eight positions of the angle-correspondence pressure plates (2) and (3). ) Is provided with a pressurizing / depressurizing device (5), and a handle (6) is attached to the pressurizing / depressurizing device (5). The present invention is an angle-compatible pressurizing / depressurizing tool for connecting rectangular steel pipes, which is configured as described above.

[0005]

[Action]

 By applying the pressure plates (2) and (3) corresponding to angles to the diagonal lines inside the square steel pipes respectively, and operating the pressurizing / depressurizing device (5) by turning the handle (6), a plurality of square steel pipes can be operated. It can be connected or disconnected from the inside.

[0006]

【Example】

 (A) Angle-corresponding pressure plates (2) and (3) are installed at both ends of the pressure shaft (1), and slip prevention screws (4) are provided at eight locations on the angle-corresponding pressure plates (2) and (3). (B) The pressurizing / depressurizing device (5) is provided at the center of the pressurizing shaft (1), and the handle (6) is attached to the pressurizing / depressurizing device (5).

[0007]

[Effect of device]

 The present invention has the above-described structure. When using this, a plurality of square steel pipes can be connected or released from the inside by operating the pressurizing / depressurizing device (5) by turning the handle (6). Easy to do.
