Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reinforcing brace for scaffolding and a scaffolding.

[0002]

[Prior art]

 Conventionally, a scaffold using a building or the like is reinforced by a brace 10 as shown in (1) of FIG. As shown in (3) of the same figure, the brace 10 has a pipe 20 formed in an intersecting shape and is pinned at the intersecting portion to be rotatable. Then, at the time of use, the tip portion was erected with the column base 40 of the scaffold 30 being pin-joined.

[0003]

[Problems to be solved by the device]

 However, the braces as described above are limited to those which can be used depending on the intervals of the column bases, that is, 1800 mm, 1500 mm, 1200 mm and 900 mm, and the braces corresponding to these intervals have been used. For this reason, it was uneconomical to have a brace corresponding to each interval. Further, since the conventional brace can be used only for the column bases having a constant interval, it cannot be used for a scaffold in which the work floor plate is inclined as shown in (2) of FIG.

The present invention has been made in view of the above problems, and an object thereof is to provide a reinforcement brace for scaffolding and a scaffolding that can cope with a change in the distance between the column bases of the scaffolding. is there.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the reinforcing brace for scaffolding according to claim 1 of the present invention is such that a length adjusting pipe is slidably inserted into both ends of an outer pipe, and the length adjusting pipe is hooked to the tip end of the length adjusting pipe. The reinforcing brace for scaffolding according to claim 2 is characterized in that the tool is rotatably screwed, and the two bracing members intersect each other and are rotatable about the intersection. The brace material is formed in such a manner that a length adjusting pipe is slidably inserted into both ends of an outer pipe, and a latch is rotatably screwed into a tip end of the length adjusting pipe. The scaffolding is a scaffolding formed by erection of a working floor board on the upper ends of column bases that are erected at appropriate intervals, and by bracing material slantingly between the column bases. The brace material Is a configuration in which a length adjusting pipe is slidably inserted into both ends of the outer pipe, and a latch is rotatably screwed into the tip end of the length adjusting pipe. Further, the brace material is provided so as to cross over the column bases and to be rotatable around the intersections.

[0006]

[Action]

 Then, when the reinforcement brace for scaffolding is installed on the scaffold, the length adjustment pipe is slid according to the distance between the column bases to adjust the length, and the tip of the length adjustment pipe is hooked. The length can be finely adjusted by rotating the tool. In addition, by using the reinforcing brace for scaffolding with adjustable length, the distance between the scaffold pedestals can be set arbitrarily.

【Example】

 Hereinafter, an embodiment of a reinforcing brace for scaffolding according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view of a reinforcing brace for scaffolding of the present invention, and FIG. 2 is a sectional view of an end portion of the reinforcing brace for scaffolding.

As shown in FIG. 1, the reinforcing brace 1 for scaffolding has length adjustment pipes 5 slidably inserted into both ends of an outer pipe 4, and a hook 6 is attached to the tip end of the length adjustment pipe 5. Is rotatably screwed.

A locking pin 7 is removably attached to the outer periphery of the rear end portion of the length adjusting pipe 5, and the locking pin 7 is inserted into the locking hole 4 a of the outer pipe 4 so that the length adjusting pipe 5 Is fixed to the outer pipe 4. The locking holes 4a are formed in the outer pipe 4 at appropriate intervals.

As shown in FIG. 2, the locking pin 7 is attached to the front end of a leaf spring 8 that is bent in a substantially U shape, and is constantly urged outward. Therefore, by pushing the locking pin 7 with a finger to remove it from the locking hole 4a, the length adjusting pipe 5 can be slid and its length can be freely changed.

The length adjusting pipe 5 can be fixed not only by the locking pin 7 but also by a set screw screwed to the outer pipe 4. This is to fix the tip of the set screw by pressing it against the length adjusting pipe 5, so that the slide length can be freely set.

The latch 6 comprises a latch piece 6 a and a bolt 6 b, and the bolt 6 b is screwed into the nut 5 a of the length adjusting pipe 5. Therefore, the length of the latch 6 can be finely adjusted by rotating the latch 6.

FIG. 3 shows an X-shaped stiffener brace 1 for scaffolding, which is formed so that two bracing members 2 cross each other and the intersecting portions are pinned, and the braces 2 rotate about the pin 3. Further, each of the brace members 2 has the same structure as the scaffolding reinforcing brace 1 of FIG. With such a configuration, the length can be adjusted according to the distance between the column bases of the scaffold.

FIG. 4 shows a scaffold using the X-shaped reinforcing brace 1 for scaffolding of FIG. 3, which is installed between column bases by changing the length of one of the brace members 2. is there. Therefore, in this scaffold, the space between the column bases can be arbitrarily changed depending on the place of use.

[0015]

[Effect of device]

 A length adjustment pipe is slidably inserted into both ends of the outer pipe, and a hook stopper is rotatably screwed into the tip of the length adjustment pipe, so that the length can be arbitrarily changed. Therefore, it is possible to cope with the change in the distance between the scaffold pedestals.

The two brace members intersect each other and are rotatably formed around the intersecting parts. In the above-mentioned brace members, length adjusting pipes are slidably inserted into both ends of the outer pipe, Since the latch is rotatably screwed into the tip portion of the adjustment pipe, it is possible to erected the X-shaped brace between the column bases according to the change in the distance between the column bases of the scaffold.

A work floor board is erected on the upper ends of the column bases which are erected at appropriate intervals, and the brace is formed on a scaffold formed by bridging the brace members diagonally between the column bases. The length adjustment pipe is slidably inserted into both ends of the outer pipe, and the hooks are rotatably screwed into the tip end of the length adjustment pipe so that the distance between the column bases can be changed arbitrarily. You can
