Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ladder device used at a construction site of a high-rise building, which is characterized by being economical and easy to handle.

[Conventional technology]

At a construction site of a high-rise building such as a building, first, a steel frame is assembled, and then various works are sequentially performed. The assembling work of the steel frame is performed by erecting column members and then joining beam members between the erect column members.

In the joining of the beam members and various operations thereafter, the worker used a ladder provided on the side surface of the column member to climb up and down.

In the conventional ladder device described above, a ladder configured according to the length of the place of use and the like is provided by being completely fixed by welding directly to the column member via the mounting rod.

[Problems to be Solved by the Invention]

Since the conventional ladder device is configured to have a length or the like suitable for the place of use, it is difficult to reuse it at other sites, is uneconomical, and is completely fixed to the pillar material by direct welding. Since it is a thing, it requires labor for installation work, addition work and removal work, and since the ladder and the attachment rod are integrated even after removal, it is bulky, transported,
It was extremely troublesome to handle such as storage.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ladder device that can be used and reused according to various sites and places of use, is economical, and is extremely easy to handle.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems. A ladder main body in which a connecting portion is formed at the upper and lower ends of each side member, and each side member can be clamped from both sides, and the side member can be slid vertically. A side bracket fixing portion that can be fixed at an arbitrary height position is formed at one end, and a mounting bracket is formed at the other end where a mounting / detaching mounting portion for the building frame is formed.

[Action]

According to the present invention, a mounting bracket b is attached to a hollow receiving piece 14 or the like which is vertically provided on the side of the building body 10 and at a proper interval.
The detachable part 11 provided at the other end of the ladder is attached to the side plate fixing part 9 provided at one end of the mounting bracket b.
The side members 1a, 1b of are fixed. Further, the ladder book a is connected and used in a length required by the comrades.

Therefore, the ladder main body a and the mounting bracket b constituting the ladder device of the present invention can be used and reused according to various sites and places of use, and can be easily attached, added, removed, and disassembled. Moreover, handling such as transportation and storage does not require any trouble.

Further, in the ladder device according to the present invention, the side plate fixing portion 9 provided at one end of the mounting bracket b has the side member 1a,
1b can be slid vertically and fixed at any height.

Therefore, since the height of the side plates 1a and 1b can be appropriately adjusted finely, the ladder device can be attached at a position that is easy to use according to the situation of the work site.

〔Example〕

An embodiment of the present invention will be described below in detail with reference to the drawings. The ladder body a has side members 1a and 1b as shown in FIG.
And a tread 1c provided with an appropriate interval therebetween.

In the present invention, the connecting portions 3 and 4 are further formed at the upper and lower ends of the side members 1a and 1b. In the embodiment shown in the drawings, the connecting portion 3 at the upper end is formed of a female metal fitting for receiving the end portions of the side members 1a and 1b, and a bolt hole 5 is provided at an appropriate position thereof.

Further, the connecting portion 4 at the lower end is left as the side members 1a and 1b, is adapted to the female metal fitting constituting the connecting portion 3 at the upper end, and is further adapted to the bolt hole 5 provided therein. 6 is provided. However, the female fitting may be a simple flat plate.

Further, the length of the ladder body a in the present invention is easily adapted to various sites and places of use, and is easy to handle such as transportation and storage, specifically, a relatively short length, for example, 1 m 40 cm. Alternatively, the length is 2 m10 cm. However, it is convenient to prepare several types.

The ladder body a of the present invention having the above-described structure is joined to the connecting portion 3 at the upper end, and the connecting portion 4 at the lower end of the ladder body a to be joined is joined, and the bolt 7 is inserted into the corresponding bolt holes 5 and 6, and the nut 8 is used. It suffices to fix them by tightening, and similarly, an appropriate number of them are connected to each other to have a required length.

Next, the mounting bracket b will be described. The mounting bracket b is provided in the horizontal direction from the building frame 10 as shown in the first drawing, and the side members 1a and 1b of the ladder body a are provided at one end thereof. The fixed part 9 is configured, and the attachment / detachment mounting part 11 to / from the building frame 10 is configured at the other end.

The side member fixing portion 9 of the present invention is composed of the side members 1a, 1 of the ladder body a.
b is slidable and can be fixed at any position. That is, a fixing plate 9a for receiving the side members 1a and 1b of the ladder body a is provided by welding at one end of the mounting bracket b, and the tip end thereof is provided with a tightening bolt 12 and a nut.
By tightening with 13, the side members 1a and 1b of the ladder main body a are clamped and fixed.

Further, the attachment / detachment mounting portion 11 to / from the building frame 10 is constructed by welding a locking rod 11a in the vertical direction of the other end of the mounting bracket b, and a cotter pin 11b for retaining is attached to the lower end thereof. It is configured to be able to.

According to the present invention having the above-described structure, as shown in the first drawing, the building frame 10
A hollow receiving piece 14 is provided by welding at a vertical and appropriate interval at the ladder installation portion, and the engaging rod 14a of the mounting bracket b is inserted into the receiving piece 14 from above to be locked, and the mounting bracket 14 is further attached. The side members 1a and 1b of the ladder main body a are clamped and used by the side member fixing portion 9 of b.

The work of mounting the ladder main body a can be performed by integrally preliminarily fixing the ladder main body a and the mounting bracket b in advance. In addition, the mounting bracket b is first attached to the building frame.
After locking to the receiving piece 14 of 10, the ladder body a may be sequentially fixed to the side material fixing portion 9 at one end of the mounting bracket b.

In the present invention, if the mounting positions of the receiving pieces 14 are provided at appropriate intervals in the vertical direction, they need not be provided at the same height on the left and right, and can be relatively rough.

FIG. 3 shows another embodiment of the attachment / detachment mounting portion 11 of the mounting bracket b to / from the building frame 10. That is, the pipe 16 is fixed by the clamp 15 between the cross beams 10a that form the building frame 10, the clamp 17 provided at the other end of the mounting bracket b is fixed to the pipe, and the ladder body a is attached at one end. is there.
