Abstract

PURPOSE:To increase the strength of the whole structure of a retaining wall by penetrating lateral reinforcements through throughholes at a buttress part of concrete blocks stacked in stages, and connecting the lateral reinforcements with each other by vertical reinforcements. CONSTITUTION:A buttress part 1b is provided at a center part on the back side of a block main body 1a, and the throughholes are bored penetrating both side surfaces. Lateral reinforcements 3 are next disposed to penetrate the throughholes. Vertical reinforcements 4 are disposed crossing these. Connection reinforcements 6 fixed along the vertical reinforcements 4 are fixed to anchor bolts 5. The lateral reinforcements 3 penetrating through concrete blocks can thus be connected freely.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to masonry retaining wall structures.

0002

[Prior Art] Conventionally, this type of masonry retaining wall was constructed by aligning vertical through holes drilled in the retaining part of concrete blocks stacked in several tiers, and inserting vertical reinforcing bars into the retaining wall. There were some that were designed to increase the structural strength.

However, in the above conventional retaining wall structure,
Not only was the structural strength of the retaining wall as a whole still insufficient, but it was also difficult to freely connect the reinforcing bars to anchor bolts etc. fixed in the embankment behind the concrete blocks.

0004

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to enable the retaining wall as a whole to exhibit sufficient structural strength; To provide a masonry retaining wall structure that can be flexibly adapted to anchor bolts, etc.

[0005]

[Means for Solving the Problems] The masonry retaining wall structure of the present invention has horizontal reinforcing bars inserted through holes in the retaining parts of concrete blocks stacked in several stages, and a plurality of horizontal reinforcing bars are connected by vertical reinforcing bars. It is characterized by

Further, the present invention is characterized in that the connecting reinforcing bars are fixed to the anchor bolts, or the connecting reinforcing bars are connected between the horizontal reinforcing bars, and the connecting reinforcing bars are fixed to the anchor bolts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 3, reference numeral 1 denotes a concrete block, which has a structure as shown in FIGS. 4 to 6.

In FIGS. 4 to 6, reference numeral 1a denotes a block body, which has a surface area approximately four times larger than that of a normal block.
For example, height (vertical dimension) 60-100cm, width (horizontal dimension)
It has a size of 120 to 180 cm. In the present invention, the size of the block body 1 is not limited to the above-mentioned specific dimensions.

[0009] A retaining portion 1b is protruded from the center of the back side of the block body 1a, and a through hole 1c is bored through both sides of the retaining portion 1b. Further, a convex portion 1d is provided in a protruding manner at the upper portion of the retaining portion 1b.

Projections 1e are formed at the lower sides of the back side of the block body 1a, and recesses 1f are formed on the lower surface of the projections 1e.As shown in FIG. It is designed to fit into the convex portion 1d of the stacked lower block body 1a.

[0011] The surface of the block main body 1a is a decorative surface, and is engraved with various masonry patterns and appropriate patterns, so that when stacked, a masonry pattern etc. is expressed as a whole.

The concrete blocks 1 constructed as described above are stacked on a foundation concrete 2 in a staggered manner, as shown in FIG.

Reference numeral 3 indicates horizontal reinforcing bars, which are arranged so as to pass through the through holes 1c of the retaining portion 1b of the concrete block 1.

Reference numeral 4 denotes vertical reinforcing bars, which are arranged so as to intersect with the horizontal reinforcing bars 3.

Reference numeral 5 denotes an anchor bolt, which is fixed to a connecting reinforcing bar 6 fixed along the longitudinal reinforcing bar 4. A plate 5a is integrally formed at the rear end of the anchor bolt 5 to improve fixing performance.

In the embankment behind the concrete block 1, geotextiles 7 are placed at appropriate horizontal intervals.
has been installed. 8 is sandbag and 9 is backfill concrete.

Next, a method of constructing the above-mentioned retaining wall will be explained. Anchor bolts 5 are installed while geotextile 7 is laid in advance to construct a reinforced embankment.

First, the first stage of concrete blocks 1 is laid, and the horizontal reinforcing bars 3 are inserted into the through holes 1c of the retaining portions 1b.

Next, the horizontal reinforcing bars 3 are welded to intersect with the longitudinal reinforcing bars 4, and anchor bolts 5 are welded to the longitudinal reinforcing bars 4 via the connecting reinforcing bars 6 fixed along the vertical reinforcing bars 4. The above operations are repeated several times to stack the concrete blocks 1 to a predetermined height.

Next, vertical reinforcing bars 4 are inserted into the back surface of the concrete block 1, and backfilling concrete 9 is poured.

[0021]

[Effects of the invention] 1) Horizontal reinforcing bars are inserted through the holes in the retaining parts of concrete blocks stacked in several tiers, and multiple horizontal reinforcing bars are connected by vertical reinforcing bars, so the structural strength of the retaining wall as a whole is sufficiently increased. You can make it work. 2) The connecting reinforcing bars are fixed to the anchor bolts, or the connecting reinforcing bars are connected between the horizontal reinforcing bars, and the connecting reinforcing bars are fixed to the anchor bolts, so the anchor bolts are fixed in the embankment on the back of the concrete block. etc., horizontal reinforcing bars inserted through concrete blocks can be freely connected.
