Hera for repairing cracks in buildings and civil structures {Crack repairing part of Hera}

The present invention is a crack repair spatula used when repairing cracks in buildings and civil structures. In particular, the main body and handle are molded integrally with a soft material with excellent elasticity such as urethane, silicone, or soft rubber, so that the grip is very good. When overlaying or leveling cracks, the work is smooth even without tilting or tilting the angle of the Hera greatly. As a result, Hera for repairing cracks in buildings and civil engineering structures so that even unskilled people can perform crack repair work without difficulty. it's about

In general, concrete walls, floor surfaces and ceiling surfaces constituting the structure of buildings and civil structures cause durability and structural problems due to aging and deterioration, and the first micro-cracks are formed over time. The width of the crack gradually increases and rainwater etc. flows into this part, which acts as a direct cause of corroding the steel bars that make up the framework of buildings or concrete structures. In addition, the generated cracks may be a direct cause of shortening the life of a building.

On the other hand, looking at the causes of cracks in concrete structures, there can be various causes such as design errors, external loads exceeding the designed loads, poor construction, physical damage, explosions, impacts, and corrosion of reinforcing bars. Types of cracks Structural cracks, plastic shrinkage cracks, plastic settlement cracks, temperature cracks due to heat of hydration, drying shrinkage cracks, cracks due to alkali/aggregate reactions, and freezing There are non-structural cracks such as cracks caused by melting and cracks caused by salt damage.

Cracks in concrete structures as described above inevitably cause various problems such as structural defects, deterioration in durability, exterior damage, and deterioration in waterproof performance. It is important.

On the other hand, as one of the mechanisms for repairing cracks generated in concrete structures including buildings as described above, there is a crack repairing hera.

The crack repair Hera usually has a main body made of rubber material such as urethane or synthetic resin material such as plastic, a handle made of synthetic resin or wood or metal material, and a fastening member such as a rivet or bolt nut that connects and assembles the main body and the handle. is made up of

The main body is mostly formed in a fan shape and is coupled to the lower part of the handle, has a shape of a narrow upper part and a lower part and becomes thinner toward the lower end, and has the same shape and structure as both sides of the front and rear sides are symmetrical.

Therefore, the crack part is filled with the crack repair material using the spatula, and flattening work is performed by covering the crack. After filling the repair material using a tool for filling the repair material, the repair material is overlaid on top of it.

However, the conventional Hera described above had structural problems as follows.

In other words, since the main body of Hera is simple with only an upper and lower beam, it was necessary to rely only on the condition and skill of the worker when filling and overlaying the crack with a repair material. When filling and overlaying the repair material on the part, it was very difficult to cover it with a uniform width and thickness, and accordingly, the crack repair work required excessive time and labor.

In particular, when repairing cracks on the walls of high-rise apartments or structures, workers have to work on ropes at high altitudes or use ladder trucks or cranes. Because there are many lines of movement along the work, it is inevitable that it will take a lot of strength and time, so even if you do not work for a long time, you will have a lot of effort and your concentration will drop.

On the other hand, when repairing cracks on the wall, etc., it is desirable to fill the crack with a crack repair material and at the same time overlay it in a thick shape. It was very difficult because of its characteristics, and therefore, the need for a crack repair Hera that can fill and overlap the crack during the crack repair process has emerged.

The present invention was invented to solve the above problems. In particular, by improving the structure of the main body of the crack repairing Hera, during crack repair work, the crack repair material is more easily filled in the cracked area and uniformly covered with a predetermined width and thickness. The purpose is to provide a crack repair Hera that can

In addition, the configuration of the front and back of the Hera body is different, but the thickness of this part is formed thinner than other parts as the groove for overlay is formed in the lower center of the front part, so that when filling the crack groove with the crack repair material, it has a uniform width It enables easy overlay with a thickness and thickness, and the back side is formed convexly so that the flattening work that spreads the crack repair material widely and evenly can be done very easily, so it is very quick and smooth when repairing cracks of various sizes and shapes. There is also a purpose to make it possible to do it.

In addition, when Hera is made of materials such as silicon, urethane, or soft rubber, the main body and the handle are integrally molded, and a reinforcing material made of ferrous metal is insert-molded inside the handle to provide excellent grip due to elasticity and soft material. The purpose is to provide a crack repair crack repair that can reduce fatigue even after long work, does not break even under severe impact, and does not require any assembly process because it is a molded product in which the main body and the handle are integrated. there is.

As shown in Figures 1 to 7, the present invention,

A structure in which the main body 2 and the handle 1 are integrally formed with the crack repair Hera 100 consisting of a short handle 1 and a main body 2 having an upper and lower shape,

형으로 개발하여 앞면은 크랙보수제(5)를 균열부위에 원활하면서도 안정적으로 충진 시킴과 동시에 균일한 두께와 폭으로 덧씌움이 가능하게 하고, 배면은 전체적으로 만곡 형성하되, 날부(21) 배면에 평탄작업용 사면(23)을 형성한 구성이 본 발명의 가장 큰 특징이다.Among the components of the Hera 100, the body 2 is a new type.

Developed as a mold, the front side allows the crack repair agent (5) to be filled smoothly and stably in the cracked area and at the same time, it is possible to overlap with a uniform thickness and width. The configuration in which the working slope 23 is formed is the biggest feature of the present invention.

Looking at the configuration of the present invention according to the above characteristics, the present invention is formed by molding the handle (1) and the main body (2) with a highly elastic soft rubber material such as silicone or urethane, and the finished product is made at the same time as molding, and the handle (1) Since it is made of the same highly elastic material as the main body 2, the grip feeling is excellent. Therefore, even if you work for a long time, you can work stably with less hand fatigue.

In addition, since the process of manufacturing the handle and the main body separately and assembling them separately is not required at all in the manufacturing process, the manufacturing process is very simple, and thus the manufacturing cost can be greatly reduced.

In addition, the present invention insert-molds the reinforcing core 3 of ferrous metal material having excellent strength inside the handle 1, so that the handle 1 ) is not bent or deformed, so crack repair work can be performed stably.

형으로 밴딩된 형태로 되게 형성하였는데, 상기

형의 본체(2)는 볼록하게 형성된 배면부분 및 사면(23)으로 인해 균열부위, 또는 그 주위에 넓게 크랙 보수재(5)로 평탄작업 할 때 본체(2)의 기울기 각도를 크게 하지 않아도 균일하게 안정적으로 평탄 작업을 할 수 있기 때문에 비숙련자도 안정적으로 크랙 보수를 할 수 있다.In the present invention, the main body 2 is formed thinner towards the lower blade 21 and thicker toward the upper part, like a spoon or fork when viewed from the side.

It was formed to be in the form of a banded shape, the

Due to the convexly formed rear part and slope 23, the main body 2 of the mold can be uniformly applied to the crack area or its surroundings when flattening with the crack repair material 5 without increasing the angle of inclination of the main body 2. Because it can perform flat work stably, even unskilled people can reliably repair cracks.

In particular, the slope 23 induces the crack repair material 5 to form a flat surface with a predetermined thickness even without increasing the inclination of the Hera 100 in the process of flattening the crack repair material 5, so that it is flat. The surface can be made very neat and tidy, and thus work efficiency is high and work reliability can also be maximized.

In addition, a concave portion 22 with a predetermined width and a predetermined depth is formed in the lower center of the front surface of the main body 2, and the lower end of the recess 22 extends outward from a position that does not reach the end of the blade 21, that is, the blade tip 21a. By forming it in such a way that it naturally expands, when filling the crack groove (4) with the crack repair material (5) and overlaying it, the lower part (21') of the lower part (22) together with the recessed part (22) acts organically. This is to ensure uniform coverage.

Therefore, after filling the crack groove 4 with the crack repair material 5, as shown in FIG. 22), the organic action of the crack repair material 5 and the blade 21' naturally forms the overlapping portion 5' with a uniform width and height, as shown in Figure 7A.

On the other hand, the height of the overlay portion 5' is proportional to the inclination angle of the Hera 100, so if the inclination angle is decreased, the height is formed low, and if the inclination angle of the Hera is increased, the height is formed.

Therefore, in the present invention, when the crack repair work is performed on the cracked part of the building and civil engineering structure with the Hera 100, the filling and overlay are performed at once, and when the work is performed using the inverted slope 23, the flattening work is performed. It is easy to do various types of crack repair work, and the work flow is reduced, so the work time and labor can be greatly reduced, and the work fatigue is significantly reduced due to the excellent grip, so the work efficiency can be maximized.

As shown in FIGS. 6 and 7, the present invention configured as described above determines the filling and overlay thickness of the cracked area according to the inclination of the Hera body 2 when the cracked area is repaired with the crack repair material 5, and the flattening operation In addition, it is configured to be very efficient, and the scope of its rights will not be limited to the above-described embodiments and drawings, and therefore, various modifications can be made within the scope of the purpose and spirit of the invention.
