The present invention relates to an equal plastering facility and an equal plastering reinforcement method using the same, a flat facility including the lower and side portions of the bridge, a angular facility including a culvert and a waterway, a curved facility including a tunnel, a circular including a pipeline The entire facility including the facility was applied.

In the past, when repairing or reinforcing a facility, an experienced cementer directly uses an ordinary trowel using inorganic cement mortar or organic resin, and sprays cement mortar or resin on the surface to be repaired by spraying. A skilled plasterer may perform the plastering work using a conventional trowel directly. These methods commonly require that the degree of plastering at the bottom of the trowel and the pressure adjustment applied to the trowel depend only on the skill of the plasterer. In addition, there is no choice but to make a different surface every time, which inevitably leads to trowel marks, which not only reduces the flatness of the surface but also makes the thickness of the plaster uniform, so that the amount of material used is not constant or the strength reinforcement is not carried out as planned. The problem is that It was a situation.

In addition, in the case of the uniform thickness plastering trowel, which is improved by attaching a blade of a predetermined height to the planned plastering thickness on the base surface of the trowel for uniform plastering, the cement mortar adheres easily around the blade. In the process of removing the marks, there was a problem that the workability and quality were deteriorated, such as uneven thickness of plastering. On the other hand, there is a method of fixing the reinforcement to the structure to be reinforced in the conventional reinforcement method after the reinforcement by cement mortar or resin, but in the process of fixing the reinforcement to the structure to be reinforced, it is fixed by fixing the anchor after drilling In addition to structural damage to the facility, and after performing a manual plastering or spraying, the trowel is finally used to perform ordinary plastering work. Therefore, the plastering angle of the plasterer's bottom and the pressure adjustment applied to the trowel are applied only to the plasterer. Not only have to rely on the skill of the worker but also different every time, because the inevitable trowel marks inevitably had a problem that the finish is not smooth.

In addition, there is a method of attaching a sheet-type reinforcement containing glass fiber or carbon fiber as an adhesive material and then plastering it with cement mortar or resin in the conventional facility reinforcement method, but using a trowel after hand plastering or spraying In the end, the general plastering process is performed. Therefore, the plastering angle of the trowel holder and the pressure adjustment applied to the trowel is not only dependent on the skill of the plasterer but also different every time. There was no problem that the trowel marks could not be made and the beauty surface was not finished smoothly.

In particular, in the case of sewage facilities including sewer pipes or culverts, it is difficult to improve the excavation during the maintenance process, so non-excavation repair reinforcement is performed to repair the inner surface of the sewage structure without digging the ground. Since a large amount of sewage flows at one time, the surface of the unexcavated repair reinforcement inner surface is as smooth as FRP or plastic surface to secure the maximum passage surface. Repair reinforcement can be activated, but in the conventional method of plastering, the plastering angle of the trowel floor and the pressure adjustment applied to the trowel is not only dependent on the skill of the plasterer but also different every time. Inevitably, trowel marks will inevitably appear on the surface. There was a problem that the use of the repair method of the refining method is limited.

In order to solve the problem that the plastering surface is not smooth and the plastering thickness is uneven as described above, the present invention is used to attach to the base surface of the structure member of the repaired facility or to open and secure it, and the height corresponding to the predetermined width and the reinforcement design thickness. A plurality of uniform thickness spacers, which are temporary materials of linear cross-section, and the pressing force applied to the trowel only on the outer surface of the uniform thickness spacers to prevent the pressure from acting on the disheveled reinforcement including cement mortar and resin. For this purpose, a uniform plastering material was constructed in combination with a trowel for uniform thickness spacers, which was a little longer than the interval between even thickness spacers.

As an embodiment using the equality plastering material, a plurality of uniform thickness spacers, which are temporary materials of linear cross section having a height and a predetermined width corresponding to the thickness of the reinforcement design space at predetermined intervals in the shape of the structural member of the facility to be repaired. After fixing the material, apply primer on the structure member, fill the dished reinforcement with the thickness of the equal thickness spacer more than the thickness, and then rub the outer surface of the multiple thickness spacers with the trowel for uniform thickness spacer which is longer than the distance between the uniform thickness spacers. Plaster the dished reinforcement smoothly at the height of the uniform thickness spacer, remove the uniform thickness spacer, apply primer to the inner surface of the equal thickness spacer demolition section where the equal thickness spacer is removed, and fill the filling reinforcement with the above plaster height. Rub it with a trowel for even thickness spacers After performing the operation section it was constructed facilities equivalents plastering reinforcement method to be closed by applying a finish coating on the reinforcement plastering.

In addition, as another embodiment using the same uniform plastering material, to remove the even thickness spacer and to apply the primer to the inner surface of the equal thickness spacer demolition of the equal thickness spacer removed and inserting the reinforcing bar after the reinforcement Fill the inner reinforcement material in the demolition part of the surrounding thicknesses with the thickness of the surrounding plaster reinforcement more than the height of the surrounding plastering material and rub it with a trowel for uniform thickness spacing to perform the plastering work. Configured.

On the other hand, instead of the equal thickness spacer and reinforcing bar, in the case of a square facility or a circular facility, it was configured to include a spiral equal thickness spacer and a spiral reinforcing bar.

As described above, the pressure applied by the plasterer to the trowel is applied only to the outer surfaces of the plurality of uniform thickness spacers, and the length is greater than the interval between the uniform thickness spacers so that no pressure is applied to the dished reinforcement material including cement mortar and resin. Plastering using a rather long uniform thickness spacing trowel makes it possible to reinforce the facility evenly and smoothly according to the design thickness of plastering to improve quality and workability.

With reference to the accompanying drawings with respect to the configuration of the present invention will be described in detail in the order of facilities equalizer, facilities equalizer reinforcement method embodiment.

According to the present invention, in order to solve the problem that the surface of the plaster is not smooth and the thickness of the plaster is uneven, the structural member 3 of the repaired facility, for example, the flat facility 1 including the lower and side portions of the bridge, is straight. In the case of a square facility (7) including a culvert and a waterway with a haunch part, in the case of a curved facility (9) in consideration of the shape of the haunch, a circular facility including a curved shape and a pipeline in consideration of the curvature of the curved member In the case of (11), it is manufactured in a circular shape and used by attaching or detaching a conventional attachment material detachable to the inner surface of the structural member 3 to be reinforced, and having a predetermined width and raising the height corresponding to the design thickness of the plastering reinforcement. On the premise of having a shape, the structure to facilitate the removal of the uniform thickness spacer 17 from the plaster reinforcement 15 even after the plaster reinforcement 15 is cured A plasterer pushes and pushes the trowel only on the outer surfaces of a plurality of uniform thickness spacers 17 and linear equally spaced spacers 17 which are attached or fixed with a trapezoidal cross section on the base surface of the ashes 3. Trowels for even-thickness spacers (19, 19 ') somewhat longer in length than the gaps between the evenly-spaced spacers (17) in order to allow pressure to act and to prevent pressure from being applied to the dished reinforcement (13) containing cement mortar and resin at all. ) And evenly spaced trowels (19, 19 ') have a single or multiple handles (top or side) of conventional plate or rod-shaped plastering members (21, 21'). 23, 23 ') is configured to run.

One embodiment using the equal amount of plastering materials described in the process order is as follows.

A plurality of uniform thickness spacers 17 including a plastic material having a linear cross section having a height corresponding to a plaster reinforcement design thickness at predetermined intervals in the shape of the structural member 3 of the facility to be repaired use a conventional attachment material. It is fixed to the base surface of the structural member 3 in the form of a temporary member by attaching or spreading.

The primer 27 is applied to the base surface of the structure member 3 using a conventional brush or a spraying equipment.

On the coated surface of the uniform thickness spacer 17 and the primer 27, a dished reinforcement 13 containing a conventional cement mortar or resin is filled to the height of the equal thickness spacer 17 or more.

Evenly spaced spacing member 13 by rubbing the outer surface of the two or more uniform thickness spacers 17 with a trowel 19 for uniform thickness spacers longer in length than the gap between the uniform thickness spacers 17. Plastering smoothly to the height of (17) to sequentially plaster so that some edge area plastered at this time overlaps some edge area plastered last time to cure the plaster reinforcement (15).

The uniform thickness spacer 17 is removed and the primer 27 is applied to the inner surface of the uniform thickness spacer removal part 25 from which the uniform thickness spacer 17 is removed.

Plastering work by filling the inner filling reinforcement (29) on the coating surface of the primer 27 on the inner surface of the uniform thickness spacer removal section 25 more than the height of the surrounding plaster reinforcement (15) with a trowel for uniform thickness spacer (19 ') The curing of the plastering reinforcement 15 is performed.

The facility uniform plaster reinforcement method was configured to finish by applying the finish coating material 31 on the cured plaster reinforcement (15).

In addition, when another embodiment using the equality of the installation material described in the process order as follows.

Plastering work by filling the inner filling reinforcement (29) on the coating surface of the primer 27 on the inner surface of the uniform thickness spacer removal section 25 more than the height of the surrounding plaster reinforcement (15) with a trowel for uniform thickness spacer (19 ') The process of curing the plastering reinforcement 15 is performed by reinforcing bars including conventional reinforcing bars, FRP rods, and resin rods on the application surface of the primer 27 on the inner surface of the uniform thickness spacer removal section 25 ( 33) and further including the filling material in the uniform thickness spacer demolition section 25 around the reinforcing bar (33) to fill the reinforcing material (29) more than the height of the surrounding plaster reinforcement (15) trowel for uniform thickness spacer (19) ') To perform the plastering work to configure the process of curing the plastering reinforcement (15).

Here, in the case of the square facility 7 or the circular facility 11 in the process of inserting the reinforcing bar 33 on the primer 27 applied surface of the inner surface of the thickness spacer removal section 25, the rectangular or circular constrained shape Therefore, the overlapped portion in the open state can be fixed by overlapping the conventional bundling line (39), so there is no need for a separate fixing means, but in the case of the planar facility (1) including the lower portion of the bridge is not separately shown in the drawings. It was comprised so that it may fix using the adhesive material containing a fastened cement mortar conventionally at the predetermined | prescribed location of the reinforcing bar 33.

On the other hand, in the case of the square facility (7) or the circular facility (11) instead of the uniform thickness spacer 17, the spiral equal thickness spacer 41 is also included in the scope of the present invention, and used instead of the reinforcement (33) Spiral reinforcing bar 43 was also configured to be used within the scope of the present invention.

In the construction process, the joint portion of the uniform thickness spacer 17 has an adhesive portion 35 connected using a conventional adhesive material, and the overlapping portion 37 of the reinforcing bar 33 uses a conventional binding line 39. It was allowed to be layered.

As described above, according to the present invention, the pressure applied by the plasterer to the trowel is applied only to the outer surfaces of the plurality of uniform thickness spacers, and evenly spaced thickness so that no pressure acts on the dished reinforcement containing cement mortar and resin. Plastering with uniform thickness spacing trowel slightly longer than the spacing between ashes improves quality and workability by reinforcing the facilities evenly and smoothly according to the design thickness of the plastering reinforcement, and when using more reinforcing bars or spiral reinforcing bars. In addition, the strength is further increased, and the effect of further improving the quality, including workability, is expected.
