DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for building blocks used for seawalls, retaining walls, and the like, and a method for fixing the same.

[0002]

Conventionally, as this type of block used for a retaining wall, as disclosed in Japanese Utility Model Laid-Open Publication No. 49-96709 or the like, a stacking block having a square flat plate portion on the front surface. Are constructed along a wall to form a retaining wall. Since the block is heavy, it is the most dangerous operation when the block is set, and it is necessary to prevent the block before being fixed from falling down and to ensure the safety of the operation.

For example, as shown in FIG. 7 of Japanese Utility Model Application Laid-Open No. 54-48933 and FIG. 6 of Japanese Utility Model Application Laid-Open No. 6-82145, in order to prevent the stacked blocks from falling over, Support the rear side with a support,
After the concrete is cast on the back of the block, the support is removed or the support is buried in the cast concrete.

[0004] However, in the case of supporting by such a support, since the support must be attached between the rear surface of the block and the slope which may fall down, there is a danger in the operation. The work was inferior in workability because the work was between the relatively narrow block rear surface and the slope.

Accordingly, the present invention is to provide a fixing device for a stacking block which can safely fix a block before concrete casting, is easy to set on the block, and is excellent in workability, and a fixing method therefor. With the goal.

[0006]

According to the first aspect of the present invention, there is provided a fixture for a concrete block for fixing an upper concrete building block which is vertically assembled along a slope. Fixture body, a lower engaging portion provided at a lower portion of the fixture body and insertable into a drain hole of the lower block, and a telescopic rod provided at the upper portion of the fixture body so as to be extendable and retractable. A stacking block fixture comprising: an upper locking portion provided on the telescopic rod for locking to an upper rear surface of the upper block; and fixing means provided on the fixing device main body to fix the telescopic rod. Yes, after inserting the lower locking part into the drain hole, expanding and contracting the telescopic rod to lock the upper locking part on the upper rear surface of the block,
By fixing the telescopic rod by the fixing means, the upper block can be fixed, and the fixture main body can be set on the block from the front side, so that the fixing operation can be performed safely and easily.

According to a second aspect of the present invention, there is provided the fixing device for a stacking block according to the first aspect, wherein the lower locking portion of the fixing device main body is rotatably provided. Into the drainage hole to set the fixture body on the block, or lock the lower locking part of one of the fixture bodies inserted into the drainage hole with the rotatable lower locking part oriented sideways. By doing so, the fixture body can be set. In addition, since the lower locking portion is rotatably provided, the fixture body can be easily set obliquely with respect to the block.

Further, the invention according to claim 3 is characterized in that the lower engaging portion of one of the fixing tool main bodies is inserted into a drain hole of the fixed lower block, and the upper retaining surface of the upper one side block is inserted into the drainage hole. The upper locking portion of one fixing body is locked to fix the upper one side block, and the lower locking portion provided laterally of the other fixing body is provided at the lower portion of the one fixing body. The stacking block fixing device according to claim 1, wherein the stacking block fixing device according to claim 1, wherein the upper fixing portion of the other fixing device main body is fixed to the upper rear surface of the upper other side block by fixing the upper locking portion. Since the fixing method is used, the upper and lower blocks can be fixed to the fixed lower block, respectively.
