Hereinafter, preferred embodiments of the mobile scaffold structure according to the present invention will be described in detail based on the attached drawings.

First, referring to FIGS. 2 and 3, the mobile scaffold structure of the present invention includes a scaffold body 100.

The scaffold body 100 includes a base frame 200 on the lower side and at least one upper frame 300 on the upper side.

As shown in FIGS. 2 and 4, the base frame 200 is made of a high-strength metal material, for example, steel or aluminum, and includes four vertical pipes 210 and 4 It consists of a plurality of horizontal pipes 220 that connect vertical pipes 210 to each other in a square shape.

The four vertical pipes 210 are arranged vertically at positions corresponding to arbitrary square vertices at intervals between each other, and a jack base 212 is installed at the bottom of each, and at the top of each Assembly protrusions 214 are respectively installed.

The lower jack base 212 has a lifting nut 212a rotatably installed on the vertical pipe 210 to correspond to the inner diameter of the vertical pipe 210, and is screwed to the lifting nut 212a. A vertical threaded rod (212b) that is inserted up and down along the inner diameter of the vertical pipe 210 while screwing in a state, and a lower end of the vertical threaded rod (212b) so that it can be supported on the ground (E) A support plate (212c) installed on and; It is configured to include a handle (212d) that can rotate the lifting nut (212a).

This jack base 212 serves to support each vertical pipe 210 of the base frame 200 on the ground E.

That is, when the lifting nut 212a is rotated through the handle 212d, the vertical screw rod 212b moves up and down, and in the process of this screw movement, the lower support plate 212c is also adjusted up and down. It is stably supported on the ground (E).

In particular, when the structure of the ground (E) of the work area is uneven, the support plate 212c is stably supported on the ground (E) while moving up and down in response to the uneven structure of the ground (E).

Due to the stable support of the support plate 212c, the base frame 200 is firmly supported on the ground E.

The upper assembly protrusions 214 protrude vertically from the top of the vertical pipe 210, and these protruding assembly protrusions 214 are formed when the upper frame 300 is assembled on the upper side of the base frame 200. It is fitted and coupled to each vertical pipe 310 of the upper frame 300.

Additionally, outriggers 216 are installed at the four corners of the base frame 200.

In particular, it is installed as an upper and lower pair on two adjacent vertical pipes 210 to connect the two adjacent vertical pipes 210 upward and downward.

These horizontal pipes 220 are assembled into a square shape with the four vertical pipes 210 by connecting two adjacent vertical pipes 210 upward and downward, and the horizontal pipes 220 assembled in this way are , four vertical pipes 210 together form a square base frame 200.

Here, the horizontal pipes 220 may be detachably connected to the vertical pipes 210 by a separate connection bracket 222.

In addition, only one or more selected specific ones may be detachably connected through a separate connection bracket 222, and in some cases, all of them may be fixedly connected to the vertical pipes 210.

That is, the horizontal pipes 220 and the vertical pipes 210 may be assembled and separated from each other, or only selected ones may be assembled and separated from each other, or they may be integrated with each other.

Here, among the multiple horizontal pipes 220 connected in a square shape with the four vertical pipes 210, the front and rear horizontal pipes 220a are arranged facing each other in the front and rear directions of the base frame 200. It is preferable that both ends are detachably connected to the vertical pipes 210 on both sides by separate connection brackets 222.

In addition, it is desirable that both ends of the left and right horizontal pipes 220b arranged facing each other in the left and right directions of the base frame 200 are fixedly connected to the vertical pipes 210 on both sides.

Referring again to FIGS. 2 and 4, the base frame 200 further includes a size adjusting unit 230 for adjusting the overall size.

The front and rear length adjusting unit 240 further includes an expansion unit 242 for expanding and contracting the left and right horizontal pipes 220b on both sides, respectively.

The expansion and contraction portion 242 is located in parallel with the left and right horizontal pipes 220b on both sides of the base frame 200, respectively, among the vertical pipes 210 in the front and rear directions of the left and right horizontal pipes 220b on both sides. , a fixed pipe (242a) fixed to one vertical pipe (210a), and a fixed pipe (242a) rotatably installed on the other vertical pipe (210b) among the front and rear vertical pipes (210). It includes a movable screw rod (242b) screwed to the inner diameter of 242a) and a rotation handle (242c) rotatably installed on another vertical pipe (210b) so as to rotate the movable screw rod (242b). It is composed by:

When the operator rotates the rotation handles 242c on both sides of the expansion and contraction portion 242 installed on both vertical pipes 210 of the base frame 200, the movable screw rods 242b on both sides rotate. .

And when the movable screw rods 242b on both sides rotate, the fixed pipes 242a on both sides screwed thereto move along the movable screw rods 242b toward the front and rear directions of the base frame 200. move

And when the fixed pipes 242a on both sides move in the front and rear directions of the base frame 200, the front and rear vertical pipes 210 on both sides also move relative to the front and rear directions of the base frame 200. do.

Ultimately, as the front and rear vertical pipes 210 on both sides move relative to each other, the telescopic left and right horizontal pipes 220b on both sides connecting the front and rear vertical pipes 210 also expand or contract. .

As a result, the size of the base frame 200 can be adjusted by adjusting the front and rear lengths (L) of the base frame 200.

Referring again to FIGS. 2 and 4, the left and right width adjustment portion 250 of the base frame 200 is composed of front and rear horizontal pipes 220a of the base frame 200 configured in a telescopic shape.
