Description

[Detailed description of the invention] The present invention - Freestanding walls such as block walls, concrete walls, etc.
This invention relates to a reinforcing structure for strongly reinforcing dyed fabrics and a method for manufacturing the same.

Conventionally, block walls and concrete walls have been widely used as enclosure walls for houses, soundproof walls for railroad M-roads, soundproof walls for urban expressways, enclosure walls for coastal structures, and the like. In most cases, these strands constitute free-standing cement-hardened walls.

These free-standing walls may crack due to earthquake vibrations or other external forces, or the cement may become brittle due to salt damage, causing them to topple over or collapse. In particular, soundproof walls on railway tracks and walls on automobile roads are constantly exposed to vibrations, so
The trend is remarkable. Conventionally, it has been impossible to reinforce such freestanding walls, for example by installing a strong concrete foundation along the bottom of both sides of the freestanding wall, erecting a steel frame on this, and attaching horizontal bars to this steel frame to hold the warm body. things will be done. However, this type of reinforcement method requires a considerable amount of time and money for foundation work, and it is also necessary to always pay attention to the rust and corrosion prevention of the steel frame, especially if it is near the seashore. The subcommittee requires extremely advanced maintenance technology.

The present invention provides a reinforced structure that does not require any foundation work to reinforce such free-standing walls, and that is extremely easy to maintain such as corrosion protection, and a method for manufacturing the same.

The present invention will be described in detail below with reference to the accompanying drawings.

FIGS. 7 to 7 are diagrams showing the steps of manufacturing the self-supporting wall reinforcement structure of the present invention.

In the figure, CII is the main body of the self-supporting wall that can be reinforced, and the base (2
) is integrally connected to the top. Usually, the above-mentioned self-supporting "4 pieces" (11) are made of concrete walls, stacked concrete blocks, etc., but from a cost standpoint,
It is rare for reinforcing bars to be placed throughout the entire structure, but only in some areas. Therefore, the intervals between the reinforcing bars are self-supporting by the concrete blocks themselves. Therefore, from above this self-supporting wall body (1), a composition (3) of rigid lath netting, punching metal, knitted wire netting, flexible synthetic resin netting, etc. The net-like materials (3) and (c) are attached to the front and back surfaces by forming and adhering them.
They are connected in parallel along both surfaces of the free-standing wall body through.

Next, as shown in FIG.
The spray gun (5) and the troweling member (4) are buried in the spray gun (5) and cured to form an integral coating. In this way, the free-standing wall book 14 as shown in FIG.
A strong hardened layer containing the mesh material (3) is formed on the outer surface of the mortar 1), and one reinforcing structure is completed. In addition, DII
The old wing of the connection part is the net-like material (S3) on the surface layer of the free-standing wall body,
(Although it may be made of a single piece of net-like material and formed by bending it into a U-shape, the inner net-like material (3), (:3 '+ may be connected in parallel.

In addition, as for the material of the hardened coating layer, for example,
I--/l', S'', 700 parts of the Bortland cement mixture No. 1J proposed in No. 23, and 5-ll of the epoxy organic polymer aqueous Maru7yon.

Polymer cement coating material made by blending parts is a bow due to its W adhesion property. I5 ridge A-1, force) 1
~The above in the present invention! The material of the first hardened layer is not limited to the above-mentioned polymer cement, and may be, for example, a naturally hardening polyester resin composition.

In the present invention, the above-mentioned self-supporting wall is provided with a net-like material on the front and back sides, and this is embedded and integrated with a hardened coating layer, so construction is extremely simple, and it can be applied not only to existing old and deteriorated walls.
It can be applied to any freestanding wall such as a newly constructed block wall or concrete wall.

Furthermore, if a lath net or the like is used for the hardened coating layer, it is lightweight, and therefore is ideal for reinforcing the side walls of elevated railway lines, the side walls of expressways, etc.
