Description

[Detailed description of the invention] This invention is designed to ensure that when panels are attached to a scaffolding frame to form a panel wall at a construction site, etc., the upper and lower edges of each panel unit and the left and right edges of each panel unit can be closely spaced without creating any gaps. The present invention relates to a panel fixture.

At construction sites, panels are attached to scaffolding frames and panel walls are assembled to prevent danger from falling objects, to prevent dust from blowing out, and to prevent noise pollution. The edges and the left and right edges are required to be in close contact with each other with no gaps.

The panel used for the above purpose has a structure roughly shown in FIG.
A clamp claw insertion hole 13 and a mounting hole 14 are provided at both ends of the horizontal frame of the rectangular frame, and a packing 15 is attached around the main body. As shown in Figure 3, the clamp claws 17 are passed through the clamp claw insertion holes of the upper and lower panels, and the clamp is tightened and fixed to the vertical pipe 18 of the scaffolding frame. However, in order to connect the panel and the clamp without any problem, the clamp insertion hole needs to have sufficient clearance for the clamp claw, and is an oblong through hole, as shown in FIG.
Therefore, even if there are gaskets on the side edges of the left and right panels, if the left and right positions of the panels are not sufficiently adjusted during installation, gaps will be created between the gaskets, which will greatly reduce the effectiveness of panel installation. This panel mounting adjustment operation is troublesome and time consuming. Furthermore, after the panels are installed, the panels often shift laterally, creating gaps, and there has been a strong demand for improvements in the installation method.

The present invention provides a gap-preventing fixing device that allows panels to be installed without any gaps even if the panels are installed using conventional installation methods, and that can prevent gaps from forming after installation. It is something to do.

An embodiment of the present invention will be described based on the drawings. As shown in FIG. 5, fitting protrusions 2A, 2B; 3A,
3B is provided protrudingly, and claw holes 4, 4 for inserting the claws of the clamp are bored. The fitting protrusion consists of a conical part 5 with a rounded tip so that it can be easily inserted into the mounting hole 14 provided in the rectangular panel frame, and a cylindrical base part 6 to firmly fit into the circular mounting hole 14. As shown in FIG. 6, the fitting protrusions are fitted into the mounting holes 14 of each panel so as to join the four panels (top, bottom, left and right) at their respective corners, thereby fixing each panel. (In the drawing, the clamp and support are omitted except for the clamp claws.) The lower end of the upper position panel touches the upper end of the lower position panel,
At this time, the thickness t of the band-shaped plate is set so that the gaskets at both ends can be sufficiently pressed together without any gaps. The thickness t of this strip plate may be set to be less than or equal to the sum of the protruding heights (thicknesses) of the gaskets of the upper and lower panels from the end surface of the horizontal frame. For example, if the protrusion height of each gasket is normally about 5 mm, then , the thickness of the strip plate may be about 6 mm.

In addition, the distance s between the ends of the fitting projections 2 and 3 is such that when installed as shown in FIG. It is set by taking into account the distance from the edge and the protrusion height from the end face of the packing.

This fixture is made of metal or synthetic resin, and in the case of synthetic resin, it can be manufactured by integral molding using a strong synthetic resin material.

The fixing device according to the present invention only needs to have the fitting protrusion securely fit into the mounting hole of the panel, and the thickness of the strip plate and the distance s between the ends of the fitting protrusion satisfy the requirements of the present invention. The shape and the shape of the fitting protrusion can be selected as appropriate. FIG. 7 shows an embodiment of another shape of the fixture. In other words, the band-shaped plate is made into a rectangular shape, and the fitting protrusion is formed into a plate-like spear shape. Even with this shape, the fitting protrusion can be firmly fitted into the mounting hole, and the manufacturing process saves material. Costs can be lowered. Note that the panel mounting holes 14 are generally already provided in the panel frame, but if they are not already provided, they may be drilled.

To use the fixing device according to the present invention, first insert the claws of the clamp into the claw holes on the upper edge of the left and right panels, and when fixing it to the column, insert the downward fitting protrusion of the fixing device into the mounting hole of each panel. When fitted using the taper of the protruding end, both the left and right panels naturally come close to each other. Next, when the mounting holes of the upper left and right panels are inserted into the upward fitting protrusions of the fixing device, the left and right panels similarly approach each other and fit tightly together. The panel seal is pressed and can be installed without any gaps. In addition, since the left and right panels are fixed by fixtures, they do not shift laterally, and they do not open and create gaps.

The fixing device for preventing gaps during panel installation according to the present invention is extremely easy to install and remove when removing the panel wall, and it fixes the panel without creating a gap, making it extremely useful for panel installation.
