Description

Piping Internal Reinforcement Device Having Ring Unit

The present invention relates to a piping internal reinforcement device, and more particularly, to a piping internal reinforcement device that can be installed as a separate support structure inside the piping to form a flow path inside the piping damaged by corrosion or damage.

When various pipes, such as sewer pipes and storm water pipes, are aged, or damaged by earthquakes or external shocks, additional reinforcement work is required depending on the degree of damage.

In general, if the degree of damage to the pipe is slight, it is possible to reinforce the part by additionally applying mortar or concrete to the inner surface, but if the degree of damage is large or wide, the entire pipe must be replaced or reinforced.

However, there are many situations in which it is practically difficult to replace the pipe, and accordingly, it is effective to reinforce the entire pipe with a reinforcing material. Accordingly, a method of reinforcing the inside of the pipe is required when the inside of the pipe is severely damaged.

As a method of reinforcing the conventional piping, a reinforcing bar or a frame is bent and installed inside the piping, an additional resin plate is combined with the rebar to form a partition wall in a cylinder type, and then a reinforcing material is filled between the resin plate and the inner surface of the pipe Curing methods have been widely used.

In the case of reinforcing materials, general cement or mortar is used, and the inside of the pipe can be reinforced through curing.

However, in the case of this method, it is difficult for the reinforcing bar or frame, etc. to maintain a fixed bond with the resin plate, and when installed in an area where there are frequent impacts from earthquakes or outside, cracks occur in the cured reinforcement with vibration of the resin plate. There is.

When cracks are generated in the reinforcing material as described above, a problem occurs in that the ground plate is flooded from the ground and the resin plate or the like is detached from the frame.

In addition, even if a flow path is formed inside the pipe using the resin plate, the fluid may penetrate into the reinforcing material through the gap between the resin plates, thereby reducing the durability of the reinforcing material and shortening the reinforcing cycle.

As described above, the piping reinforcing device used in the related art has reinforced the piping by installing a resin plate on the inner surface of the piping and filling the reinforcing material therebetween. However, since the holding strength of the resin plate is relatively weak, the durability is maintained even when reinforced. It is difficult to do.

Therefore, a method for solving these problems is required.

11 is a view showing a state in which each component is combined in the pipe internal reinforcement device according to the fourth embodiment of the present invention.

In the case of the fourth embodiment of the present invention shown in FIG. 11, the first passage forming portion is not provided in the first coupling unit 200, and the shape of the fixing unit 800 is formed differently from the above-described embodiments.

As described above, in the present exemplary embodiment, since the first passage forming portion is not provided, the space of the connecting passage S can be used more widely.

In addition, in the present embodiment, the fixing unit 800 has a first insertion portion 810, a width smaller than that of the first insertion portion 810, and a second insertion engaged with a pair of auxiliary hooks 354 Includes part 820. That is, the fixing unit 800 has a'T' shape on a cross section, and empty spaces may be formed on both sides of the second insertion unit 820. Such a space can be utilized as accommodating various configurations therein as in the connection passage S.

As described above, the preferred embodiments according to the present invention have been examined, and the fact that the present invention can be embodied in other specific forms without departing from the spirit or scope of the embodiments described above has ordinary knowledge in the art. It is obvious to them. Therefore, the above-described embodiments are to be regarded as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description and may be changed within the scope of the appended claims and their equivalents.
