Description

[0001] GUTTER CONSTRUCTION EQUIPMENT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gauge construction apparatus, and more particularly, to a gauge construction apparatus capable of remarkably reducing a construction cost and a construction period of a gauge.

Sewage is used to drain sewage such as storm water. It can be divided into a method of being installed in the factory after it is moved to the site, a method of making a mold in the field, and a method of making a mortar in a mold by sticking.

Of these, the sash formed by direct pouring in the field is advantageous in that it can be easily manufactured in various shapes, can actively cope with the bending of the ground, and has a low probability of occurrence of leakage.

On the other hand, it requires a lot of manpower to construct a mold to determine the shape of the sphere during construction, has a disadvantage of long construction period, and has a disadvantage that the construction cost is higher than other construction methods.

In this way, it is a reality that the gauges made by directly putting them in the field have many advantages and disadvantages.

Various methods have been developed to secure the advantage of spotting and to secure the disadvantages. These methods have been applied in such a manner that the floor is poured after the bottom of the side wall is sufficiently cured and the side walls are laid on both sides.

If the floor and the side wall are separately laid without being laid in such a way as to pour the gauges, buoyancy may be generated in the inner frame by the mortar when the pouring unit is integrally installed. If the bucket is raised by such buoyancy, This is because the mortar is lost through the lower part of the exterior, making it impossible to manufacture the sphere itself.

For this reason, when constructing the sphere, it is common to divide the sidewall into a floor and a side wall. In order to improve this, there have been cases in which a construction method is integrally installed, for example, the application form No. 20-2007-0006059 'mold form manufacturing form'. However, this design also requires a lot of manpower to make a mold to determine the shape of the cross section, and it is difficult to solve the disadvantage that the construction period is long because many assembling members forming the form are used.

It is an object of the present invention to provide a side wall construction apparatus capable of reducing the cost required for construction of a side wall and remarkably shortening the construction period.

Hereinafter, a process of constructing the V-shaped cross section using the cross-sectional construction apparatus according to one embodiment of the present invention will be described.

First, excavate the ground at the location where the survey site is installed, and perform the terra cotta.

Next, the pillars 20 are installed in the ground so as to adjoin the inner wall surfaces on both sides in the ground. At this time, the column 20 is installed along the longitudinal direction of the ground.

Next, the fiber mold 100 is placed in the ground. At this time, a number of fiber molds 100 may be installed along the longitudinal direction of the ground, and styrofoam may be positioned between each adjacent fiber mold 100 to prevent friction of each adjacent fiber mold 100 have.

Next, the concrete is injected through the second concrete injection hole 216 formed in the guide member 200 and the first concrete injection hole 119 of the corresponding fiber mold 100 into the inner space of the fiber mold 100 .

The injected concrete is filled in the inner space of the fiber formwork 100 to form a cross-sectional shape of the V-shaped cross-section by each of the surfaces of the fiber form 100. At this time, The deformation of the upper surfaces of the fiber formwork 100 is not generated by twisting, whereby the cross-sectional shape of the V-shaped cross-section can be easily formed.

Thereafter, the concrete filled in the inner space of the fiber form 100 is subjected to a curing period so as to be cured in a V-shaped cross-sectional shape.

When the concrete curing period is over and the concrete is cured, the column 20 and the guide member 200 are removed from the inside of the ground 1.

Finally, the construction process is terminated by carrying out a back-up process of filling up the soil around the V-shaped platform 10 installed in the ground.

After this construction process is completed, the fiber form 100 can be cut and removed.

In addition, since the V shape can be manufactured through a single concrete injection and curing process using the fiber form 100, the construction period can be remarkably shortened.

Hereinafter, a pointing apparatus according to another embodiment of the present invention will be described with reference to FIGS. 4 and 5, focusing on differences from the pointing apparatus according to an embodiment of the present invention. FIG. 4 is a cross-sectional view illustrating a side wall construction apparatus according to another embodiment of the present invention, and FIG. 5 is a perspective view illustrating the anti-skid member shown in FIG.

4, according to another embodiment of the present invention, the apparatus for constructing a side view further includes a plurality of anti-skid members 300 installed on the inner surface of the outer bottom surface 111 of the fiber form 100 Are the same as those of the gauge construction apparatus according to the embodiment of the present invention. Therefore, a plurality of the anti-skid member 300 will be described below.

4 and 5, the plurality of anti-jamming members 300 include a base plate 310, a fixing pin 320, a pair of linkages 330, and a pin housing 340.

The base plate 310 is fixed to the inner surface of the outer bottom surface 111 and an opening 310a is formed at the center. For example, the base plate 310 may be circular.

The fixing pin 320 includes a head portion 321 and a pin portion 322 extending downward from the head portion 321. The fixing pin 320 is disposed above the base plate 310, So as to face the opening 310a.

The pair of links 330 allows the fixing pin 320 and the base plate 310 to be connected to each other. To this end, the upper ends of the pair of connecting rods 330 are connected to the head portion 321 of the fixing pin 320, and the lower ends of the connecting rods 330 are connected to the base plate 310. Each connecting rod 330 is formed with a notch 331 formed perpendicular to the longitudinal direction thereof. The notch portion 331 is formed on the inner surface of each linkage 330 so that each linkage 330 can be easily folded in a direction away from the pin portion 322 of the fixation pin 320. When each connecting rod 330 is folded, the fixing pin 320 descends toward the base plate 310.

Here, the base plate 310, the fixing pins 320, and the pair of connecting rods 330 can be easily attached to and fixed to the fiber form 100, and are formed of a plastic material so as to be integrally connected to each other. As a result, the pair of connecting rods 330 are made of plastic and can be easily folded because they form the notch 331.

The pin housing 340 is coupled to the pin portion 322 to surround the outer surface of the pin portion 322 of the fixing pin 320 and the pointed portion 341 is formed at the lower end portion. The pin housing 340 is made of a metal material and a pointed portion 341 is formed at a lower end thereof. The pin housing 340 penetrates the fiber mold 100 when the fixing pin 320 is lowered toward the base plate 310 so that the fixing pin 320 contacts the outer bottom surface of the fiber mold 100 (Not shown).

The concrete construction apparatus according to another embodiment of the present invention is characterized in that when the concrete is injected into the inner space of the fiber formwork 100, The head portion 321 of the fixing pin 320 of the anti-jamming member 300 is pressed, and at this time, the pair of connecting rods 330 are separated from the pin portion 322 of the fixing pin 320 by the notch portion 331 . The fixing pin 320 is lowered in the direction of the base plate 310 so that the pin portion 322 is inserted into the opening 310a of the base plate 310 and the pin housing 322, The pin portion 322 and the pin housing 340 of the fixing pin 320 are protruded to the outside of the fiber mold 100 by drilling the outer bottom portion 111 of the fiber mold 100. [ The pin portion 322 and the pin housing 340 of the protruding fixing pin 320 are stuck to the grounded ground 1.

The fin portion 322 of the fixing pin 320 of the fiber mold 100 and the pin housing 340 are stuck to the ground 1 and the fiber mold 100 is moved in the longitudinal direction of the ground 1 .

On the other hand, a wear-resistant coating layer is formed on the entire outer surface of the spherical guide member 200 of the above embodiments. Here, the wear-resistant coating layer is formed by spraying a powder of a mixture of 96 to 98% by weight of chromium oxide (Cr2O3) and 2 to 4% by weight of titanium dioxide (TiO2) onto the entire outer surface of the guide member 200, And a thickness of 50 to 600 mu m, and the hardness is plasma-coated to maintain 900 to 1000 HV.

The abrasion resistant coating layer is formed by spraying a powder composed of 96 to 98% by weight of chromium oxide (Cr2O3) and 2 to 4% by weight of titanium dioxide (TiO2).

The reason why ceramic coating is applied to the entire outer surface of the guide member 200 is to prevent abrasion and corrosion. Compared to chrome plating or nickel chrome plating, the ceramic coating is excellent in corrosion resistance, scratch resistance, abrasion resistance, impact resistance and durability.

Chromium oxide (Cr2O3) acts as a passivity layer that blocks oxygen entering the inside of the metal, thereby preventing rusting.

Titanium dioxide (TiO2) is a white pigment because it is very stable physicochemically and has high hiding power. And is also widely used for ceramics having high refractive index because of high refractive index. And has characteristics of photocatalytic property and superhydrophilic property. Titanium dioxide (TiO2) acts as an air purification function, an antibacterial function, a harmful substance decomposition function, a pollution prevention function, and a discoloration prevention function. This titanium dioxide (TiO2) ensures that the wear-resistant coating layer is completely covered on the entire outer surface of the guide member 200 and dissolves and removes foreign matter adhered to the wear-resistant coating layer to prevent damage to the wear-resistant coating layer.

When chromium oxide (Cr 2 O 3) and titanium dioxide (TiO 2) are mixed and used, the mixing ratio thereof is such that 2 to 4% by weight of titanium dioxide (TiO 2) is mixed with 96 to 98% by weight of chromium oxide (Cr 2 O 3) desirable.

When the mixing ratio of chromium oxide (Cr 2 O 3) is less than 96 to 98%, the coating of chromium oxide (Cr 2 O 3) is often broken in an environment such as a high temperature, The rust preventive effect of the rust decreased.

When the mixing ratio of titanium dioxide (TiO2) is less than 2 to 4% by weight, the effect of titanium dioxide (TiO2) is insignificant so that the purpose of mixing it with chromium oxide (Cr2O3) is discolored. That is, titanium dioxide (TiO 2) decomposes and removes foreign matter adhering to the entire outer surface of the guide member 200, thereby preventing the entire outer surface of the guide member 200 from being corroded or damaged, If the amount is less than 2 to 4% by weight, it takes a long time to decompose the attached foreign matters.

The coating layer made of these materials is plasma-coated on the entire outer surface of the guide member 200 to have a thickness of 50 to 600 mu m, a hardness of 900 to 1000 HV, and a surface roughness of 0.1 to 0.3 mu m.

The wear-resistant coating layer is sprayed by spraying the powder powder and the gas at 1400 캜 onto the entire outer surface of the guide member 200 at Mach 2 at a speed of about 2 at a speed of 50 to 600 탆.

If the thickness of the wear-resistant coating layer is less than 50 탆, the above-mentioned effect of the ceramic coating layer can not be guaranteed. If the thickness of the wear-resistant coating layer exceeds 600 탆, the above- There is a problem that working time and material cost are wasted.

The temperature of the entire outer surface of the guide member 200 is increased while the entire outer surface of the guide member 200 is coated with the abrasion-resistant coating layer. This prevents the entire outer surface of the heated guide member 200 from being deformed The entire outer surface of the guide member 200 is cooled by a cooling device (not shown) so as to maintain a temperature of 150 to 200 ° C.

A sealing material made of anhydrous chromic acid (CrO3) made of a metal-based glass quartz system may further be applied to the periphery of the abrasion-resistant coating layer. Anhydrous chromic acid is applied as an inorganic sealing material around a coating layer made of chromium nickel powder.

Anhydrous chromic acid (CrO3) is used in places that require high abrasion resistance, lubricity, heat resistance, corrosion resistance and releasability, is not discolored in the atmosphere, has high durability, and has good abrasion resistance and corrosion resistance. The coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m. If the coating thickness of the sealing material is less than 0.3 占 퐉, the sealing material easily peels off even in a slight scratch groove, so that the above-mentioned effect can not be obtained. If the coating thickness of the sealing material is made thick enough to exceed 0.5 탆, pin holes, cracks, and the like will increase on the plated surface. Therefore, the coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m.

Therefore, since the coating layer having excellent abrasion resistance and oxidation resistance is formed on the entire outer surface of the guide member 200, the entire outer surface of the guide member 200 is prevented from being worn or oxidized, thereby prolonging the service life of the product.

Meanwhile, the pin housing 340 is formed of a nodular cast iron. The nodular cast iron is heated to a temperature of 1600 to 1650 ° C to be molten, then subjected to desulfurization treatment, and subjected to spheroidizing treatment at a temperature of 1500 to 1,550 ° C by adding a spheroidizing agent containing magnesium in an amount of about 0.3 to 0.7% by weight, followed by heat treatment.

Since nodular cast iron is a cast iron in which graphite is spherically crystallized during the solidification process by adding magnesium or the like to the molten metal of the common gray cast iron, the shape of the graphite is spherical compared to gray cast iron. Since the nodular cast iron has a small notch effect, the stress concentration phenomenon is reduced and the strength and toughness are greatly improved.

The pin housing 340 is made of a nodular cast iron which is heated to 1600 to 1650 캜 to be molten and then subjected to a desulfurization treatment. A spheroidizing treatment agent containing about 0.3 to 0.7% by weight of magnesium is put into the pin housing 340 and spheronized at 1500 to 1550 캜 Followed by post-heat treatment.

Here, when the nodular cast iron is heated to less than 1600 ° C, the entire structure is not sufficiently melted. If the cast iron is heated above 1650 ° C, unnecessary energy is wasted. Therefore, it is preferable to heat the nodular cast iron to 1600 to 1650 ° C.

When the amount of magnesium is less than 0.3% by weight, the effect of injecting the spheroidizing agent is negligible. When the amount of magnesium is less than 0.3% by weight, the effect of injecting spheroidizing agent is insignificant. When the amount of magnesium is less than 0.3% There is a problem in that an expensive material cost is increased. Therefore, the mixing ratio of magnesium in the spheroidizing agent is preferably about 0.3 to 0.7% by weight.

When the spheroidizing treatment agent is injected into the molten nodular cast iron, it is subjected to spheroidizing treatment at 1500-1550 ° C. If the spheroidizing treatment temperature is lower than 1500 ° C., the spheroidizing treatment is not properly performed. If the spheroidizing treatment temperature is higher than 1550 ° C., the spheroidizing treatment effect is not greatly improved, but unnecessary energy is wasted. Therefore, the spheroidization treatment temperature is preferably 1500 to 1550 ° C.

Since the pin housing 340 is formed of the nodular cast iron, the stress concentration phenomenon is reduced because the notch effect is small, and the strength and toughness are greatly improved.
