Description

  TECHNICAL FIELD The present invention relates to a tensioning plate installation tool that simplifies the tensioning work so that the position and height direction can be easily determined when stacking concrete blocks and the like.

There are the following methods as a general tensioning work for block stacking that has been performed conventionally.
Two piles separated from each other were driven so as to be perpendicular to the ground, and a plate called water drainage was attached to these piles while maintaining a horizontal state perpendicular to the piles. A vertical plate, also called a through plate, is attached so as to be perpendicular to this horizontally arranged drain, and the blocks can be stacked with a water string that supports the height of the block to be stacked on this through plate It was like that. The above-mentioned work for stacking the blocks is a tension work.
As another method for stacking blocks, an exclusive ruler 1 with a scale 2 is fixed in an L-shape that touches two sides of the end corners of the installed block, and block stacking is performed using this ruler as a guide. There is a concrete block stacker. (For example, refer to Patent Document 1).
Further, when the curb G is near the block to be stacked, the curb installation leg 10 is attached to the curb G, and the rotation support mechanism 20 and the support mechanism 30 for adjusting the stacking angle of the block are provided. There is a construction tensioning device in which a tensioning material retaining member 70 for attaching a water thread is attached to the retaining member gripping mechanism 40 provided. (For example, refer to Patent Document 2).
Japanese Utility Model Publication No. 3-108153 (first page, FIG. 1) Japanese Unexamined Patent Publication No. 2006-291596 (page 9, FIG. 1)

Traditionally, the tensioning work that has been carried out generally has the disadvantage that not only can the piles not be driven when the ground surface is concrete pavement, but that the tensioning work is troublesome even when it is soil.
Further, the concrete block stacking device shown in Patent Document 1 attaches the ruler 1 to the block itself to be stacked, and therefore, the ruler cannot be attached unless the block is completely fixed. In addition, this first block had to be secured without tension.
When the ruler 1 was attached without fixing the block, the block moved during the attachment of the ruler, which had a great disadvantage that it was easy to perform block stacking work with low reliability.
In addition, if the verticality of the block to which the ruler 1 is attached is poor, there is a disadvantage that the block becomes an inclined block.
Furthermore, because the ruler 1 and the block are in close contact with each other, no joints can enter, so the joint cannot be finished unless the ruler is removed.
When the blocks are stacked, the blocks are joined together with mortar, but in order to achieve a more complete bond, use a little more mortar than necessary and tap the stacked blocks from the top to raise the height. Was adjusted so that excess mortar was devoured from the joints.
This protruding mortar may cause the ruler attached to the block to move or tilt, which causes the construction reliability to deteriorate.
Therefore, this ruler 1 requires a device called a swing-down swing 5 for the purpose of accurately performing the verticality.
The construction tensioning device shown in Patent Document 2 cannot be used unless there is a curb G near the block fence to be stacked, and the rotation support mechanism for angle adjustment because the apparatus is mounted at a position away from the block fence. 20 and the support mechanism 30 are also required, which not only makes the structure complicated and troublesome to handle, but also has the great disadvantage of becoming an expensive device.
The present invention has been made in order to eliminate such drawbacks, and attaches a through-plate mounting tool to a base part for stacking the blocks, and attaches the through-plates in a state of being separated from the stacked blocks. The purpose of the present invention is to provide a tension plate installation tool for a stringer.

Means for Solving the Invention

In order to solve the above problems, the present invention has the following configuration.
The stringing plate installation tool according to claim 1 is a U-shaped mounting body for mounting a base end portion on which blocks to be stacked and both side walls of the stacked blocks are sandwiched. By providing a through-plate holder for mounting a through-plate that sets the height direction of the block in a state of protruding from the closed end portion and spaced from the end face of the foundation or the stacked block, It was.
According to such a tensioning plate installation tool for tensioning, it is possible to set the stacking height of the block by using the foundation part and the stacked block without stacking the work as in the past. The plate can be easily installed in a state of being separated from the block.
According to a second aspect of the present invention, the tension plate installation device for the tensioning device is configured such that the through plate holding body according to the first aspect is attached to the holding body by inserting the through plate from the side.
According to such a tensioning plate installation tool for tensioning, it can be easily attached and moved more simply by moving the through plate to the side.
According to a third aspect of the present invention, there is provided a tensioning plate installation tool according to the first and second aspects of the present invention. A plate installation tool was used.
According to such a tensioning plate installation tool for tensioning, the arrangement position of the through plate can be changed with respect to the foundation, so that the through plate can be moved to a convenient position according to the situation at the construction site, Narrow penetrating plates can be installed.

Effect of the invention

According to the present invention, the following effects can be obtained by attaching the through plate using the base portion of the block to be stacked or the stacked block.
The troublesome work and nailing work of driving a pile into the ground and attaching a water drain plate to be mounted horizontally on this pile are no longer required, as in the case of a conventional tensioning work.
Since there is no need for a special ruler to be attached to the block, there is no possibility of moving the block while the blocks are being stacked, and there are no parts that cannot be finished with joints.
The tensioning plate installation tool of the present invention has a simple structure and does not require an angle adjustment, so that it can be easily attached to and detached from the foundation portion and the stacked blocks, and the arrangement of the through plates is also simple.
