Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a block wall such as a retaining wall or a block wall and its elastic engagement pin.

[0002]

2. Description of the Related Art In conventional block wall construction methods,
When stacking side wall blocks on the bottom or side wall concrete blocks (hereinafter simply referred to as side wall blocks), evenly apply mortar to the top surface of the bottom or side wall block face shell and back shell, and then place the side wall blocks on top of it. It was on top.

[0003]

However, the above-mentioned mortar takes a long time to be kneaded, and the kneading requires a skill, and until the mortar is hardened (for about 3 days), the bottom remains. Alternatively, there is a drawback that the kneading concrete cannot be poured into the side wall block and the construction period is long.

Therefore, the present invention does not require kneading of mortar, and therefore does not require a skilled worker, and an object thereof is to provide a method of constructing a block wall and a resilient engaging pin for construction which are short in construction period.

[0005]

As shown in FIG. 1, the means for solving the problems according to the present invention fixes the base portions 6a of a plurality of vertical reinforcing bars 6 to a plurality of bottom side wall blocks 5A and skewers the plurality of vertical reinforcing bars 6. As described above, the soft buffer strips 12 are adhered to the upper surfaces 8a and 10a of the face shells 8 and the back shells 10 of the plurality of adjacent bottom wall blocks 5A, and a large number of stacking side wall blocks 5 are superposed on the soft buffer strips 12 so as to overlap each other. Adjacent to each other, the first and second web shells 9A and 9B of the lower stack side wall block 5
One lower surface 9b and the first and second web shells 9
The upper surface 9a of the first and second web shells 9A and 9B of the upper product side wall block 5 located immediately above one of A and 9B are engaged and connected to each other by the elastic engaging pin P, and the above steps are performed. Is repeatedly performed between the lower product side wall block 5 and the upper product side wall block 5, and is a method of constructing a block wall.

[0006]

In the above means for solving the above problems, since the conventional spacer function of the mortar is replaced by the soft buffer zone 12 and the adhesive function of the mortar is replaced by the elastic engagement pin, it is not necessary to knead the mortar, so that skilled work is required. It is possible to realize a block wall construction method that requires no personnel and has a short construction period.
