Abstract

PURPOSE:To easily turn-over a steel material safely and noiselessly by supporting a steel frame for construction etc. between a steel material compulsory revolving apparatus and the steel material insertion hole on a disc rotatably supported on a supporting part equipped with a roller, and revolving said steel material by a revolving machine. CONSTITUTION:A steel plate 17 is inserted into a disc 16, which is supproted on the holding plates 14 equipped with rollers 15 which are installed onto two bodies 4 veritcally constructed on a base plate 2 equipped with casters. The other edge of the steel plate 17 is held on a steel material revolving apparatus. When the steel material revolving apparatus is revolved in this state, the disc 16 is revolved on the rollers 15 and turned-over, together with the steel material 17. The holding plate 14 equipped with a roller is constituted so as to be slidably moved vertically in the longitudinal straight through-groove 8 on the body 4, and the inner edge part of the holding plate 14 in the body 4 is engaged with a plurality of stepped parts arranged inside the body 4 and not shown in the figure, permitting the position to be held, and the holding height can be varied by changing the engaged stepped part. With such a constitution, steel material can be turned-over easily safely, and noiselessly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a disk reversing device capable of freely reversing a disk holding structural steel materials or the like.

Traditionally, for welding beams to steel columns.

Mainly, this was done either with the steel column in a grounded state or by suspending the steel column in the air with a chain, etc., but when these methods were used, it took a long time to reverse the welded steel column on the negative side. In addition, there were disadvantages such as the danger associated with the reversal and the significant deterioration of the working environment due to the vibration and noise of the crane and the like.

The present invention aims to solve the above-mentioned drawbacks, and its purpose is to provide a pair of internally hollow columns above both ends of a base plate with castors at the bottom, A column groove is formed vertically in the center of the inner plate of the body, and horizontal step portions are arranged at predetermined intervals on the inner surface of the outer plate of the cavity in the column body; Forming a tip plate having a rear portion placed on a horizontal step provided inside the column and having a front end surface touching the inner surface of the inner plate of the column, projecting integrally from the tip plate. The above-mentioned drawbacks can be overcome by providing a disk reversing device that includes a protruding plate that can freely pass through the row grooves and a roll holder that rotatably holds the rotating roll at the tip of the protruding plate. The objective is to solve all of these problems and to make it easier to weld the beam downward to the steel column.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the accompanying drawings.

A pair of pillars (4) with a hollow interior (3) are standing above both ends of the base plate (2), which is equipped with casters (11) at the bottom.

The column (4) is bent in the middle from a hinge 09 disposed on the outside of the central portion of its height. The connection between the lower column (&a) and the upper column (</b) is achieved by inserting the fixing rod (6) into the shaft hole (5) drilled near the joining position.0Column 14) The central longitudinal direction and straight groove of the inner plate (7) (
8) is provided.

Furthermore, horizontal step portions fl(l
It is necessary to form.

Therefore, as mentioned above, the pillar body (a) is made of plywood (2), the pillar f41, the straight transparent groove (8) in the center of the column of the inner plate (7) constituting the pillar body (4), and the pillar body (f41). It mainly consists of a horizontal step (1) formed on the inner surface of the outer plate (9) of the body (4).

On the other hand, the rear of the base plate aυ located in the cavity (3) of the column (4) and inclined at approximately 20° to θ0@degree is placed on the horizontal step (1G). and its front end is the medial plate (
7) In addition to the canopy surface a that comes into contact with the inner surface of D, a protruding plate flll is integrally provided to protrude from this base plate αυ.

This protruding plate α3 has a thickness slightly smaller than the groove width of the permeable groove 18) so as to be able to pass through the straight permeable groove (8). Roll holding plate +t
aK x is a rotating roll (1!19) which is rotatably held.

Therefore, the roll holder (1)) is attached to the base plate (1) as described above.
It mainly consists of lυ, a protruding plate u3, a roll holding plate I, and a rotating roll 19.

If the rear end of the roll holder (b) is placed on the upper part of the horizontal step (lO) provided inside the column (4), the weight of the front part will cause the support surface (11) of the base plate (11) to 12) is the inner plate (7
) comes into contact with the inner surface of the When the rotating roll (15) at the front part of the roll holder (b) is loaded, the inclined base plate (11) is placed in the internal cavity (3) of the column (4). It will be held even more firmly.

When trying to change the height position of the roll holder (b), lift the front part of the roll holder (b) (as shown in Figure 3) and align the canopy surface (12 with the inner plate (7) and the inner surface). If the base plate (11) is separated from the inner cavity (3) of the column (4)
can be moved freely.

(16) is a disk that holds a section of steel frame material (17) such as HwI, and the other end of this steel material (17) is a rotary plate (18 ) is fixed.

As mentioned above, if the steel material (disk fta holding 1η) is placed on the rotating roll (15J) of the roll holder Steel frame material: Promotes smooth rotation of disk 1161 while holding 171.

As described in 7Lh of this invention, a pair of pillars each having an internal cavity are placed above both ends of a plywood board provided with castors at the bottom, and a column groove is formed in the longitudinal direction in the center of the inner side plate of the pillars. is installed in a straight line,
In the column, a column includes horizontal steps arranged at predetermined intervals on the inner surface of the outer plate of the cavity, and a rear portion placed on the horizontal steps provided inside the column. A base plate is formed whose front end surface touches the inner surface of the inner plate of the column, and a protrusion plate is provided that integrally protrudes from this base plate and can freely pass through the row grooves. Since it is composed of a roll holder at the tip that holds a rotating roll in a rotating body, it is easy to change the holding position according to the length of the steel material, and it is also possible to easily change the holding position according to the length of the steel material. Since the rotation is smooth and the steel material can be easily reversed, the welding of the beam to the column steel material can always be done downward, allowing for good penetration. Moreover, the swimming position of the steel material can be changed up and down arbitrarily easily and quickly without using any tools, and has an excellent effect.
