Description

[Detailed Description of the Invention] The present invention relates to a scaffold board connector for construction.

At construction sites such as new construction or renovation of general wooden houses or buildings, scaffolding using metal pipe scaffolding materials is erected around the site, and scaffolding boards are erected based on this scaffolding, and construction workers use this scaffolding as a base. They are used to move around on boards and perform various tasks, as well as transport construction equipment. Scaffolding boards are long objects, but there is a limit to their length, so when erecting multiple scaffolding boards along a scaffold, the ends of adjacent scaffolding boards should be overlapped in the length direction of the scaffolding boards to make them continuous. It is becoming more and more used. However, if the overlapping ends of adjacent scaffolding boards shift laterally, there is a risk that the worker will misstep and fall, and even if the worker does not fall, the scaffolding may become unstable. This makes it impossible to perform the work smoothly.

This invention stabilizes the scaffolding boards by connecting and fixing the overlapping ends of adjacent scaffolding boards when multiple scaffolding boards are installed in a row in the length direction as described above, and the work can be carried out smoothly without the risk of falling. The purpose of the present invention is to provide a scaffolding board connection tool that can be used to connect scaffolding boards.

An embodiment of the coupling device of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2, a connector main body 1 is formed of a movable body 2 and a fixed body 3, which are formed by bending two band-shaped metal plates having robustness and are connected to each other so as to be openable and closable.

The movable body 2 has a shape in which one end of a band-shaped metal plate is bent downward to form a connecting plate 2a, and this connecting plate 2a is provided with a hook portion 4 that bulges outward in a semicircular shape. have Furthermore, the fixed body 3 has connecting plates 3a and 3b formed by bending both ends of a band-shaped metal plate upward, and one connecting plate 3a has a hooking portion 5 that can be hooked into the hooking portion 4. It has a given shape.

A base 2b of the movable body 2 on the opposite side to the connecting plate 2a and a connecting plate 3b of the fixed body 3 are connected by a shaft 6 so as to be movable in opening and closing.

Reference numeral 7 denotes a pressing plate, which is attached to the tip of a bolt 8 screwed into the connecting plate 3b so as to be able to reciprocate in the direction of the connecting plate 3a.

Note that 9 is a reinforcing nut fixed to the connecting plate 3b, into which a bolt 8 can be screwed.

A rectangular frame is formed by engaging the hooking portion 4 of the movable body 2 and the hooking portion 5 of the fixed body 3.

The present invention has the above-mentioned configuration, and the movable body 2 is lifted in the direction of the arrow to be in a fully open state, and the fixed body 3 is
Insert. In this state, if the movable body 2 is closed and both the hooks 4 and 5 are engaged, the two scaffolding boards 10 will be held between the movable body 2 and the fixed body 3. Then, turn the bolt 8 to advance the pressing plate 7,
If the scaffolding board 10 is pushed toward the connecting plate 3a, the scaffolding board 10 will be fixed within the rectangular frame.

According to the present invention described above, the movable body 2 and the fixed body 3 made of strong metal plates are connected by the shaft 6 so as to be able to open and close, and are also connected by the hook parts 4 and 5.
Since it can be fixed, it is possible to sandwich and fix the two superposed scaffold boards 10.

Moreover, the pressing plate 7 that can move forward and backward is replaced by the bending plate 3.
b, the scaffolding board 10 can also be fixed between the pressing board 7 and the bent plates 2a and 3a in the engaged state, and the overlapping parts of the scaffolding board 10 are stably connected.
It will be fixed.

Note that the movable body 2 and the fixed body 3 may be reinforced by forming ribs thereon.
