[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work surface lining block for fixing a lining block to a work surface by means of a detention means attached to the lining block.

[0002]

2. Description of the Related Art Japanese Patent No. 2983207 discloses an anchoring method (anchor) in which a retracting means attached to a lining block is embedded in a construction surface lined by the lining block to fix the lining block on the construction surface. As a concrete means thereof, as shown in FIGS. 1 to 10 and the like, as shown in FIG. 1 to FIG. Fixed to, the bar is extended to the rear of the lining block, or the end of the bar is embedded and integrated during molding of the concrete lining block to extend the bar to the rear of the lining block, A plate member, which is a resistor, is movably attached to the extended end of the rod member so as to improve the retention effect. In actual field construction, the above structure is often used.

[0003]

The above anchor construction method is used when a block is piled up to construct a steep revetment wall.
It has an effect that each block can be stably retained on the construction surface. However, since the rod having rigidity is extended to the rear of the lining block for a long time, it becomes a hindrance when a large number of lining blocks are brought into the site by a truck or the like, and the efficiency of stockpiling and transporting is hindered. In addition, there is a problem that the bar material is deformed when the stock is transported.

In the above prior art example, in order to deal with the above problem, a method is shown in which a ring portion is provided on the end portion of the bar and the lining block as shown in FIG. However, according to this method, it is necessary to individually connect the bar members to a large number of blocks at the site with connecting metal fittings,
Workability is significantly deteriorated.

[0005]

The present invention provides a construction surface lining block that appropriately solves the above problems.

According to the present invention, in the anchor construction method using the above-mentioned anchoring means, the anchoring means is formed of a rod and the end portion of the anchoring rod is bent to form a locking ring, while the above-mentioned construction surface is used. A locking groove is formed on the outer peripheral surface of the lining block, and the locking ring is inserted into the locking groove to connect the lining block and the pulling rod to form a construction surface lining block.

According to the construction surface lining block, both can be easily connected by simply pushing the retaining ring of the pulling rod into the locking groove of the lining block at the construction site. Can be removed and separated from the lining block for bulk storage and transportation.

Further, the pulling means is formed of a rod, and the extending end of the pulling rod is bent in a direction intersecting with the rod to form a resistor. This solves the problem in the case where the resistor is formed from a plate material which is a separate component.

When the pulling means is formed of a rod and a plate is used as the resistor, a stopper for preventing the plate from advancing and retracting is provided at the extending end of the rod so that the position functioning as a resistor is set at each position. Secure in the lining block.
