Description

[Detailed description of the invention] <Industrial application field> This invention relates to a reinforced structure that prevents the block wall from collapsing during an earthquake by pasting rust-free high-performance fibers onto the block wall.

<Conventional technology and problems> Many existing block walls are insufficiently reinforced;
In some places, even plain ones are used.

Therefore, there was a risk that even a mild earthquake could cause the block wall to collapse, causing harm to third parties passing by.

<Purpose of the invention> This invention was created in view of the existing problems, and was designed to prevent block walls from collapsing even in the event of a major earthquake, allowing third parties such as passersby to evacuate with peace of mind.

<Structure of the invention> In order to achieve the above-mentioned purpose, this invention attaches a tape-like or string-like high-performance rust-resistant fiber to an existing block wall with an adhesive. It is characterized by extending the fibers to the base of the block wall. The rust-free high-performance fiber used in this invention refers to fibers that do not rust, such as carbon fiber, Kepler fiber, and stainless steel fiber.

<Embodiments> Hereinafter, preferred embodiments of this invention will be described with reference to the accompanying drawings.

The block wall 1 is usually constructed by stacking blocks 3 using vertical reinforcing bars embedded in the foundation 2.

The back side of this block wall 1 (the side that does not face the road)
A rust-proof high-performance fiber 4 processed into a tape or string shape is pasted on with an adhesive. The anti-rust high performance fiber 4 is extended and pasted to the base 2 of the block wall 1 in the vertical direction, and is also pasted in the horizontal direction if necessary. The rust-free high-performance fiber has excellent tensile strength, so if it is attached to the back side of the block wall 1,
Even in the event of an earthquake, the front side will not easily fall down, and if you have a problem with the block wall collapsing on the back side, you can reinforce the front side of the block wall by pasting rust-resistant high-performance fibers on it as well.

<Effects of the invention> This invention is constructed as explained in the examples above, and since the rust-resistant high-performance fiber itself is lightweight, it is easy to handle, and even an amateur can easily reinforce a block wall. The block wall, which was about to collapse during an earthquake, is held in place by high-strength, rust-free, high-performance fibers, which has the advantage of allowing third parties such as passersby to evacuate with peace of mind.
