Description

[Detailed description of the invention] Industrial application field This invention relates to temporary metal pipes used for retaining wall construction, side gutter construction, etc.

Conventional technology In the past, 7.5cm columns were usually used as temporary supports to support weir boards and wall panels during retaining wall construction and gutter construction.
A corner timber square post is used, the lower end of which is nailed to a stake driven into the ground or a square lumber placed on the ground, and the upper end of which is nailed to a panel crosspiece, with diagonal and approximately horizontal connections between the two. The panel is supported in an upright position.

Problems that the invention aims to solve The temporary supports for conventional wall panels are wooden square pillars as mentioned above, and in order to securely support the panels by nailing, large nails (usually 4-inch nails) must be used. Moreover, since nails were driven into the ends, cracks occurred after one use, making continuous use impossible.
In addition, since large nails are used, the material cost for the nails also increases, resulting in high costs. Furthermore, the construction requires at least two people, a nailer and a panel supporter, because the nails must be driven in the correct position along the concrete wall that forms the panel. there was.

The present invention was devised in view of the above-mentioned circumstances, and is a temporary pipe for civil engineering and construction that is strong, can be used continuously for a long time, and can be easily constructed by one person using small nails. The purpose is to provide.

Means for Solving the Problem The above object is to connect a hinge member in which the flat fixed piece has a nail hole and the rotating piece has a connecting hole, and the lower end is flattened and connected. A lower stage pipe has a hole formed therein and its upper end serves as a connecting part with the upper stage pipe, an upper stage pipe whose upper end part is flattened and a connecting hole formed therein, and a connecting hole formed near its lower end and an upper stage pipe. an upper mounting piece formed of a thin flat plate with a nail hole formed in the upper part; the lower pipe is rotatably connected to the rotating piece of the hinge member; and the upper pipe is connected to the lower pipe. The structure is characterized in that the upper mounting piece is connected to the upper pipe so as to be able to swing approximately 180 degrees. This can be achieved by adopting

Effects The effects will be explained based on drawings corresponding to examples.

Even if the lower end of the temporary pipe 1 is fixed to the fixing member, the upper end of the temporary pipe 1 can freely move up and down in elevation with respect to the fixing member, so the temporary pipe 1 can be set at any angle. In addition, since the lower pipe 3 is rotatable relative to the hinge member 2, the temporary pipe 3
can be fixed to the panel member at any angle, even if it is not perpendicular, and the mounting position of the panel can be freely selected. Furthermore, the upper pipe 4 can be rotated and adjusted so that the mounting surface of the mounting piece 5 attached to the upper part of the upper pipe 4 is always in surface contact with the mounting surface of the panel, and the installation of the panel can be adjusted. The upper mounting piece can be nailed to the panel without considering the angle, and after finishing, the length of the upper stage pipe 4 can be adjusted to position and fix the panel.
Therefore, the construction can be carried out by oneself without requiring personnel to support and position the panels. Furthermore, the temporary pipe can be attached to the panel at any location, either on the upper horizontal surface or on the vertical surface. Moreover, the mounting piece is approximately 180° to the upper pipe.
Since it is swingable, you can freely fine-tune the fixing position to the panel.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 to 3 show examples of temporary pipes according to the present invention. The temporary pipe 1 of the present invention is composed of five members: a hinge member 2, a lower pipe 3, an upper pipe 4, and an upper mounting member 5, all of which are made of metal. The hinge member 2 has a nail hole 7 provided in one rotating piece for nailing to a fixed member 6 such as a stake set on the ground or a prismatic material maintained horizontally, and a nail hole 7 provided in the other rotating piece. A connecting hole is formed through which a connecting tool 8 such as a bolt or screw is inserted to connect the lower pipe 3 so as to be rotatable through approximately 180°. In addition, the lower end of the lower pipe 3 is flattened to form a connecting hole for insertion of a connecting tool,
It constitutes a connecting portion to the hinge member. Also,
The upper end of the lower pipe 3 is a connection part with the upper pipe 4, and the connection part has an adjustment hole through which an adjustment tool 9 is inserted to connect the upper pipe 4 in a rotatable and length-adjustable manner. A nut 10 is welded and fixed to the surface thereof. In this embodiment, the rotation and length of the upper pipe 4 relative to the lower pipe are controlled by the adjustment tool 9, the adjustment hole formed in the lower pipe 3 for inserting the adjustment tool, and the nut 10. Although the connecting means is configured to adjustably connect the two pipes, it goes without saying that the connecting means is not limited to this, and other known means for connecting two pipes in a rotatable and adjustable length manner can also be used. The upper end of the upper pipe 4 is flattened to form a connecting hole, and constitutes a connecting portion to the upper mounting piece 5. Furthermore, the upper mounting piece 5 has a connecting hole formed near its lower end and a nail hole formed in its upper part.

As shown in FIG. 1, each member configured as described above is rotatably connected to the lower pipe 3 to the hinge member by a connector 8, and then the upper pipe 4 is inserted into the upper part of the lower pipe 3. Temporary pipe 1 Assemble.
Using such temporary pipe 1, panel 11
The support is performed as follows. First, the hinge member 2 is fixed with nails to a fixing member 6 fixed on the ground parallel to the panel at an appropriate distance from the temporary position of the panel. The panel 11 is erected in a predetermined position, the upper stage pipe 4 is appropriately rotated, the upper mounting plate is adjusted so as to come into surface contact with the panel mounting surface, and the upper mounting piece 5 is fixed to the panel mounting surface with nails. At that time, the mounting position can be finely adjusted by rotating the mounting piece as appropriate. After installation, the angle of the panel is adjusted by moving the upper pipe in and out of the lower pipe as appropriate, and the adjuster 9 is tightly tightened and fixed. Similarly, a plurality of temporary pipes are strung diagonally or approximately horizontally between the fixture and the panel to support the panel. Note that when the temporary pipe 1 is hung diagonally and the upper mounting piece is fixed to the top side of the panel as shown in Figure 2, the fixing surface of the upper mounting piece will be inclined to the top side of the panel, but it is necessary to hammer the nails. Sometimes the upper mounting piece is easily bent by a hammer. Note that a piece bent in advance may be prepared as the upper mounting piece.

Effects Since the present invention is configured as described above, it has the following excellent effects.

The relative position of the bottom end, which is the end to be attached to the fixed member, and the top end, which is the end to be attached to the panel, can be adjusted in all directions, including up and down, left and right, rotation, and axial length, making temporary panel installation work easier. It is flexible and can be easily done, and since the angle of inclination of the panel can be adjusted after nailing both ends, the work can be done independently.

Since it uses metal pipes, it can be used repeatedly, and running costs are dramatically lower than traditional wooden temporary supports. Furthermore, unlike wood, there are no cracks, and the fixing surface is always in surface contact with the mounting surface, so it can be firmly fixed.

Furthermore, since the nailing part is a thin flat plate, small nails can be used, and there is no need to use large nails like with conventional wooden supports, which reduces nailing time and saves money on nails. .
