Description

[Detailed Description of the Invention] The present invention relates to a construction block that can be inspected from the outside when adding reinforcing bars to be inserted into blocks to be stacked, and can prevent the stacked blocks from deforming or collapsing.

As is well known, when stacking blocks in multiple stages, reinforcing bars must be added. At this time, if the reinforcing bars to be added are not in the desired condition, the strength will decrease, so check whether the reinforcing bars to be added overlap for a certain length and whether the joints are sufficiently filled with filler concrete. There must be.

However, in conventional blocks, the connecting portion for adding reinforcing bars is located inside the reinforcing bar insertion hole of the block, so it is virtually impossible to inspect.

Furthermore, since the resistance between the back surface of conventional blocks and the slope of the construction site is relatively small, the stacked blocks may slide and collapse due to earth pressure.

This proposal was devised in view of the above, and includes opening inspection holes on the surface of the block body that communicate with the reinforcing bar insertion holes to make it easier to inspect the reinforcing bar addition status and the filling status of joints with filler concrete from the inspection holes. , By putting chestnut stone etc. into the V-shaped groove formed on the back side, the resistance to sliding between the back side of the block and the slope of the construction site is increased,
This prevents the stacked blocks from collapsing.

Hereinafter, the present invention will be explained with reference to the embodiments shown in the drawings. 1 is a thick plate-shaped block body having upper and lower end surfaces 2, 3, left and right end surfaces 4, 5, a front surface part 6, and a back surface part 7, A protrusion 8 is formed along the length direction on the upper end surface 2, and the lower end surface 3 and the left and right end surfaces 4,
A groove portion 9 is formed along the length direction in 5. Vertical reinforcing bar insertion holes 10, 10 are bored left and right at regular intervals in the block body 1 from the upper end surface 2 to the lower end surface 3.

The surface portion 6 has the above-mentioned reinforcing bar insertion holes 10 and 1.
Inspection holes 11, 11 communicating with the surface portion 6 are formed, and a shallow hooking hole 12 is formed in the center of the surface portion 6. This hooking hole 12 is for hanging a crane or the like when stacking the block bodies.

In addition, a V-shaped groove 13 is provided in the back surface portion 7 along the length direction.
Form multiple pieces horizontally at regular intervals. This V
The grooves 13 are used to increase the resistance to sliding of the chestnut stone or waste concrete inserted between the back of the stacked blocks and the slope of the construction site, thereby preventing the blocks from collapsing.

The case of stacking using the block body 1 constructed as described above will be explained with reference to Fig. 4. The bottom of the construction site is filled with chestnut stone a, and reinforcing bars b of a certain length in the vertical direction are extended upward. Root hardening block 14
is placed on the chestnut stone a, and a paver block 15 with reinforcing bars b inserted therein is installed on the upper end surface of the foot protection block 14.

Next, the lowermost block 16 in which the reinforcing bars B are passed through the reinforcing bar insertion holes 16b is fixed to the upper surface of the paving block 15, and the reinforcing bar insertion holes 16a are filled with filler concrete. If the length of the reinforcing bar b extending from the block 16 is shorter than the height of the next block to be stacked, a reinforcing bar b' is added to the upper end of the reinforcing bar b, and then the block bodies 1 of the present invention are stacked. In this case, pass the reinforcing bar b through the reinforcing bar insertion hole 10 of the block body 1 from the reinforcing bar b' to the reinforcing bar b, and observe the connection part b'' between the reinforcing bar b and the reinforcing bar b' from the outside by facing the inspection hole 11. Fill the inside with filler concrete.

In addition, in order to stack the blocks to the third stage from the bottom, insert the reinforcing bar insertion hole 16a of the same block 16 as the block 16 of the lowest tier into the supplementary reinforcing bar b' extending upward from the reinforcing bar insertion hole 10 of the block body 1. and fix it to the upper end surface of the block body 1.

In this way, the block 16 without an inspection hole and the main block body 1 are stacked one after another.
When the reinforcing bars become short while stacking the blocks, they are added, and the proposed block body 1 is used at the place where the reinforcing bars are added, and the upper block 17 is installed at the top.

In this way, when the block body 1 of the present invention is used for connections where reinforcing bars are added, the state of reinforcing bars being added and the filling state of filler concrete in the joints of reinforcing bars can be observed through the inspection hole 11, thereby preventing incomplete connections of reinforcing bars. If so, you can correct it, or if the filler concrete is insufficient, fill it through the inspection hole. After the inspection, the inspection hole 11 is filled with filler concrete.

Therefore, during construction, the construction block of this project can check and correct the connection state of reinforcing bars and the filling state of filler concrete in the joints, thereby preventing a decrease in strength due to improper connection of reinforcing bars. be able to. In addition, since there are hook holes on the surface, they can be stacked by mechanically clamping them, and after construction, these hook holes can be filled with mortar and closed.

In summary, the present invention has the advantage of being able to easily check the connection state of reinforcing bars and the filling state of filler concrete in the joints after construction, as well as ease of construction work and practical value. Moreover, the V-shaped groove on the back side is filled with maroon stone and waste concrete that is filled between the back side of the block and the slope, so it prevents the stacked blocks from deforming or collapsing when earth pressure is applied. can do.
