Definition of Terms

Steel pipe: In the present invention, a steel pipe means a horizontal member of a scaffold, not necessarily a steel pipe, but all members constituting a scaffolding horizontal member. It can be carried out with any cross-sectional structural material such as pipes.

Scaffolding: Scaffolding refers to scaffolding scaffolding, but since the shipyard still uses the word "chief", which is a Japanese expression, the present invention uses a scaffold and a chief.

Chieftain: means the scaffolding of an industrial scaffold.

The present invention is not a scaffold system such as a scaffold of a conventional system scaffold for fastening both ends of a foot plate (PD) to a steel pipe (SP). The scaffold body and the steel pipe, which are generally used in shipyards, (Hereinafter referred to as " fastening device "). In the present invention, a conventional annealing wire is used, but the annealing wire is U-shaped so as to surround the bottom portion of the steel pipe. The annealing wire is brought up to the upper portion of the foot plate and is brought into contact with the U- The length of the U-shaped member is adjusted by tightening the bolts and nuts so that one end of the foot plate is engaged while the other is fixed by the use of bolts and nuts. To a prefabricated foot clamp. To this end, the present invention is characterized in that a bar-like member such as a round bar or a square bar having a length corresponding to the footstool width is mounted on the diameter of a steel pipe and both ends are connected to the upper end of the U- (RO direction) along the circumference of the steel pipe as shown in the right side of FIG. 2, and then an assembling means for fastening or loosening the free end using a mechanical fastening means such as a bolt is provided. do.

In other words, the U-shaped member is provided at the right and left sides of the plane portion at right angles at both ends of the plane portion, and the one side is fixed to one side of the foot plate Shaped member which is rotated in the direction of the arrow. 1, which is a U-shaped member at the front face of FIG. 1, is a stationary pressurizing portion 10, which is tightened at a right angle with the plane portion and which rotates as a U- (30), and tightening while adjusting the length of the U-shaped member is referred to as a fastening portion (40). The fixed pressurizing portion 10 presses the steel pipe, but is fixed to the plane portion. The rotary pressurizing portion rotates around the steel pipe and pressurizes but before the pressurization. The fastening portion 40 means a device for completely tightening the steel pipe and the foot plate. As shown in FIG. 1, the flat portion 20 is a member that tightens the flat portion of the foot plate while being on the left and right sides of the steel pipe section, as shown in FIG. 1 And is divided into a left side plane portion 25 and a right side plane portion 26.

The present invention is a device using a method of fastening a steel pipe and a foot plate by using annealed wire, so that a steel plate is placed on a steel pipe and the annealed wire is U-shaped so as to surround the steel pipe on one side of the foot plate, In order to allow the work of closing the opening of the U-shaped wire after the steel pipe is rolled down after it is turned back down, the foot clamp according to the present invention is used in order to insert the steel pipe as a complete U- The portion of the rotary pressing portion 30 is opened as shown in the right side of FIG. And a steel pipe on the right and left sides of the foot plate is wrapped through the space to press the foot plate through the fastening portion.

As shown in FIG. 1, the present invention provides a U-shaped structure for enclosing a steel pipe, including a fixed pressing portion 10 having a fixed portion adjuster 13 at its lower end, A right side flat portion 25 having one end connected at right angles to the right end of the fixed pressing portion 10 and the other end connected to a right side flat portion 26 , One end of the U-shaped structural member is fastened by one end of the left flat surface portion 21 and the hinge 31 in the direction of one end, the rotary part adjuster 34 is provided at the lower end and the arm fastener 33 is provided at the other end And a fastening part (40) having a rotation pressing part (30) and a stopper (42) inserted in the guide. 3 shows a detailed structure of members according to the present invention.

As shown in the left side of FIG. 2, the fixed pressing portion 10 having the U-shaped structure surrounding the steel pipe and having the fixed portion adjuster 13 at the lower end thereof is made of a U-shaped rod-like structure material such as annealing wire, Is folded at a length obtained by adding the lengths of the first and second sides. As a special structure of the present invention, the axis-like hinge 11 can be used to fold the rectangular portion at this folding portion, which is advantageous in that it is easy to use by reducing the area when moving the material.

The left side flat portion 25 having one end joined to the left end of the fixed pressing portion 10 at right angles is a portion of the left side flat portion 25, Anyone can do this through the drawings and photographs shown in Fig.

The right side flat portion 26, one end of which is joined to the right end of the fixed pressing portion 10 at right angles and the other end to which the guide 22 is joined, It will be understood by those skilled in the art that the above description may be implemented by anyone skilled in the art from the drawings or photographs shown in Figs. The guide can be welded to the end of the round bar with a structural material with a hole larger than the outside thread diameter of the bolt, or a structural material such as a conventional pipe or washer.

One end of the U-shaped structural member is fastened by one end of the left flat surface portion 21 and the hinge 31 in the direction of one end, the rotary part adjuster 34 is provided at the lower end, and the rotation with the arm fastener 33 Since the pressing portion 30 surrounds the steel pipe and rotates around the hinge in the cross direction to cover the steel pipe, it is preferable to place the cross-directional hinge 31 on the upper part of the steel pipe as much as possible. To do this, the flat part should be shaped like a C shape so that it can cover the footing. FIG. 6 is an exemplary view showing that the flat portion is shaped like a letter C to cover the foot plate. The female fastener 33 is a member which is joined to the free end of the rotation part press-in member 32 as shown in one embodiment in FIG. 3, and since the female fastener 33 forms a pair with the lower end of the male fastener 41, You can use a nut. Since the rotation member press-in member is a linear structure member, the arm fastener 33 must be joined so as to be coaxial with the linear structure member. This is because the end of the linear member is branched into a Y-shaped member and the nut is horizontally placed on the Y- do. Since the female fastener 33 is a fastening member paired with the male fastener 41 of the fastening part, the expression "Female & Male" is used, so that the concept of the male fastener and male fastener can be understood. Since the cross-directional hinge 31 for rotating along the circumference of the steel pipe follows the circumferential direction of the steel pipe, it is defined as the cross-sectional direction.

The fastening part 40 having the stopper 42 inserted into the guide may be fastened to the arm fastener 33 by a pair of bolts having a head part. When the bolt is inserted into the guide 22 and the nut is inserted, a guide is provided between the nut and the head of the bolt, so that the bolt can not always be detached from the guide. The stop 42 is located between the bolt head and the end of the bolt thread as shown in one embodiment in FIG. 5 to prevent the fastener from being displaced about the guide 22. As a result of this stopper, the fastening part always becomes one body without being separated from other members. The distance between the stopper and the guide (22) shall be determined in consideration of the distance to be inserted into the arm fastener. The free end of the bolt must be easily assembled with the arm fastener 33 so that the fastening part 40 is assembled only when the axis centers of the arm fastener and the male fastener 41 are aligned. For this purpose, the lock member E as shown in Fig. 6 is placed on the hinge foundation on the cross-directional hinge so that the rotation pressing portion is not wrapped around the steel pipe, . The lock member E is fixed to the rotation part press-in member 32 and has an arm extending in the direction of the male fastening part of the fastening part, and the arm further comprises elastic arms capable of quickly surrounding the outer circumference of the male fastening part Structure. The free end, which is not the head part of the male fastener, shall be provided with a guide means to make it easy to insert into the female fastener.

The fixing portion adjuster 13 and the rotating portion adjuster 34 at the lower end of the U-shaped member may be formed of bolts inserted into the lower end of the U-shaped member and inserted into the U-shaped member. . The compression strength varies through the length of the bolt inserted through the female thread. Since the fixing portion adjuster 13 and the rotating portion adjuster 34 have a structure in which the nut is joined to the middle of the round bar or the square bar, the structure may be such that a circle is formed in the straight line.
