Description

Scaffolding with reinforcement removable structure}

The present invention relates to a scaffolding frame having a detachable structure of reinforcement bars, and more particularly, by connecting one side pillar of the first main frame and one side pillar of the second main frame through a central bar and a plurality of reinforcing bars in a collapsible manner so that an operator can install the scaffolding frame by himself. It relates to a frame scaffold having a detachable structure of a reinforcing bar that allows installation, but improves installation workability and transportability by connecting and detachably connecting the reinforcing bar through a detachable means so that it can be separated and transported when necessary.

In general, frame scaffolding is installed at a construction site to safely and efficiently work at a high part.

This frame scaffolding consists of a first main frame, a second main frame, an X bar (X bar), a scaffold, etc., the first main frame and the second main frame are erected vertically and installed apart from each other, and the first main frame It is installed by connecting and fixing the second main frame to the X-bar, and placing the scaffolding on the upper surface.

However, since all parts of such a conventional frame scaffold are separated, it is not easy for an operator to install it alone, and there is an inconvenience in that two people usually have to install it together. That is, depending on the situation of the construction site, it is necessary to quickly install the frame scaffolding alone, move it, and then reinstall it. However, the conventional frame scaffolding cannot be dismantled and installed alone, and then installed quickly at another site after moving.

Therefore, Republic of Korea Patent Registration No. 10-0151942 discloses a collapsible frame scaffold that a worker can install alone.

However, the conventional frame scaffold disclosed in the above patent has the advantage of being able to be installed alone because it is composed of a folding type, but has the disadvantage that it is not easy to transport alone due to its weight. That is, the conventional frame scaffold disclosed in the above patent is heavy because it is lifted and moved at once after folding, so it is not easy to carry alone, so there is a problem that two people must carry it or use a separate tool to carry it.

By forming a hook groove 420 corresponding to, it can be configured to be detachable from each other in a hook coupling method. Of course, the hook protrusion 410 and the hook groove 420 may be configured opposite to each other.

In addition, as shown in FIG. 4, the detachable means 400 is provided with a male connection portion 430 having a male screw portion formed on the outer surface of the reinforcing bar 300, and the inner surface of the column coupling unit 150 and the sealing unit 220. The female connection portion 440 formed with the female screw portion may be installed to correspond to the male connection portion 430 so as to be detachable from each other in an outgoing coupling method. Of course, the male connection part 430 and the female connection part 440 may be constructed opposite to each other.

In addition, as shown in FIG. 5, the attaching and detaching means 400 is formed so that the fitting pieces 450 protrude from the ends of the column coupling band 150 and the sealing coupling band 220, and the fitting pieces ( 450) and corresponding fitting groove 460 is formed, and the fitting piece 450 is inserted into the fitting groove 460 in the fitting hole 470 penetrating the fitting piece 450 and the fitting groove 460. After inserting through the bolt 480, it can be configured to be detachable from each other in a bolt coupling method in which the nut 482 is fastened and fixed. Of course, the fitting piece 450 and the fitting groove 460 may be configured opposite to each other.

In addition, although the pin coupling method is not shown, in FIG. 5, a pin may be inserted into the fastening hole 470 instead of a bolt, and then the end portion may be fixed by a rivet method.

In addition, although the coupler coupling method is not shown, a known coupler for connecting rods to rods may be applied.

Of course, the above-described hook coupling method, screw coupling method, bolt coupling method, and pin coupling method are also described as an example and can be applied in various configurations.

Now, the installation and transportation relationship of the frame scaffold having the reinforcement attachment and detachment structure according to the present invention configured as described above will be described.

When installing the frame scaffold according to the present invention, the reinforcing bar 300 is connected to the central bar 200 and the first main frame 100-1 and the second main frame 100-2 through the detachable means 400 in a straight line. After unfolding, as shown in FIG. 6, the first main frame 100-1 and the second main frame 100-2 are rotated to face each other so that the first main frame 100-1, the reinforcing bar 300 and the second main frame ( 100-2) is placed in a U shape. Then, as shown in FIG. 7, the ends of the first main frame 100-1 and the second main frame 100-2 opposite to the reinforcing bar 300 are connected through the X-bar connecting protrusion 130 to the X bar (X Bar) 10 is connected to each other, and the first main frame 100-1 and the second main frame 100-2 are connected to each other by placing the scaffold 20 on the corresponding connecting rods 120 to complete the installation.

After using these frame scaffolds, when transporting them to another place, they can be folded and transported at once, or if necessary, they can be completely separated and transported.

That is, when the frame scaffold is folded and transported, only the scaffold 20 and the X-bar (X-bar) 10 are separated, and then the first main frame 100-1 and the second main frame are folded while the central bar 200 is folded inward. (100-2) can be folded so that they overlap each other. Then, the frame scaffold can be lifted and transported by two people.

Next, when the frame scaffold is separated and transported, the scaffold 20 and the X-bar (X-bar) 10 are first separated, and then the detachable means 400 is separated and the first main frame 100-1 as shown in FIG. ), the second main frame 100-2, the reinforcing bar 300, and the central bar 200 are all separated. Then, the frame scaffolding components can be loaded and transported by one person on the vehicle.

As described above, since the frame scaffold having the attachment/detachable structure of the reinforcing bar according to the present invention is configured to be collapsible, the worker can install the frame scaffold alone, and the reinforcing bar can be detached from the first main frame, the second main frame, and the central bar through a detachable means. Because it is configured as possible, it has a feature that the frame scaffold can be easily separated and transported alone.

As described above, the present invention has been shown and described in relation to specific embodiments, but those skilled in the art can make various modifications and changes without departing from the spirit and scope of the invention indicated by the claims. Anyone who grows up will easily understand.
