Abstract

The present invention relates to a manufacturing method of the H-beam coating material, and in particular, in order to prevent the soil from collapsing and falling down after ground excavation in civil engineering or building construction of the H-beam in order to be able to easily pull out without unreasonable ease It relates to a coating agent which can be applied to a surface.

As is well known, when strengthening the foundation in civil engineering and construction or when constructing the basement, H-beams are fixed around the ground to be excavated before the ground is first excavated to a considerable depth, and the soil collapses between the beams. The wooden panel is fixed to prevent it, and after completion of construction, all H beams are pulled out.

However, it is difficult to fix the H beam firmly in the coastal region or the ground where it is weak. Therefore, the method of fixing the H beam using cement mortar, such as the grouting method, is adopted. In this case, the H beam is pulled out after construction. It is very difficult to do the H-beam, which causes excessive labor and time-consuming defects when drawing the H-beam.In severe cases, the H-beam cannot be pulled out and buried in the ground, causing huge material waste and the environment caused by the corrosion of the beam. Pollution occurs.

Accordingly, an object of the present invention is to provide a method for producing an H-beam coating agent by diluting 50 to 70% of pyramid wax, 30 to 40% of solid lubricant, 2 to 5% of diesel oil, and 1 to 3% of silicon at high temperature. If the H beam is fixedly installed along with cement mortar after applying it to the H beam, the H beam can be easily removed by lubrication of the coating agent after construction.

Description

Manufacturing method of film for H beam {Manufactory method of made in membrane for 'H' baem}

The present invention relates to a manufacturing method of the H-beam coating agent, and more particularly, so that it can be easily pulled out without difficulty when pulling the H-beam used to prevent the ground from collapsing in the process of excavating the ground during civil engineering or building construction It relates to a coating agent which can be applied to the surface of the H beam.

As is well known, when strengthening the foundation in civil engineering and construction, or when constructing the basement, the H-beams are fixed around the surface to be excavated and the soil is collapsed before the ground is excavated first. In order to prevent it from falling down, wooden panels are fitted and all the H beams are pulled out after the construction is completed.

However, in coastal areas or where the ground is weak, it is difficult to fix the H beam firmly. Therefore, the cement is hardly fixed using cement mortar like the grouting method, or the surrounding ground is firmly fixed using various hardeners. The method of fixing the beam is adopted, and in this case, it is very difficult to pull out the H beam after construction, which leads to an excessive increase in labor costs along with defects that require excessive manpower and time when pulling the H beam. Unable to pull out the beam, it causes huge material waste in the ground and environmental pollution due to corrosion of the beam.

In addition, when the H-beam is firmly installed by cement mortar as described above, when the H-beam is forcibly drawn out by using various machines or H-beam drawing machines, cracking of the underground part of the building or structure is caused. Its durability is greatly reduced and the lifespan is shortened as well.

Therefore, it is urgent to prepare a solution to solve this problem.

The present invention has been made in view of the above-mentioned conventional problems, and in particular, to provide an H-beam coating agent that enables the H-beam to be easily pulled out without any problem even if the H-beam is fixed using cement mortar or hardener in the soft ground. In order to achieve the above object, the H-beam coating agent is prepared by diluting pyramid wax 50 to 70%, solid lubricant 30 to 40%, diesel oil 2 to 4%, and silicon 1 to 3% at high temperature, and H beam When applied to the coating agent is to solidify at room temperature to form a film between the H beam and cement mortar to make it very easy to pull out the H beam after construction.

In manufacturing the H-beam coating material which is applied to the surface of the H-beam, so that the H-beam can be easily drawn out even when used with cement mortar on the soft ground.

The H-beam repellent is paraffin wax 50-70% (preferably 60%), solid lubricant 30-40% (preferably 35%), diesel oil 2-4% (preferably 3%), silicone 1 ~ 3% (preferably 2%) is mixed and melt-mixed at a temperature of 70-90 ° C. to complete the preparation.

Herein, the solid lubricant refers to grease, and it is preferable to use a slightly inferior viscosity, and silicon serves to adhere the coating agent to the H-beam surface well, and paraffin wax is used to prevent the penetration of cement water and the like.

The present invention configured as described above is described as follows.

<Example>

60% of paraffin wax, 35% of solid lubricant, 3% of light oil, and 2% of silicon were melted at 80 ° C., and then applied repeatedly to a thickness of 2 mm on the H-beam surface by spraying before solidifying.

Subsequently, after the coating part was solidified, the H beam was installed on the cemented mortar using cement mortar, and then pulled out after completion of the underground structure.

In other words, the coating agent of the present invention is to apply and adhere to the surface of the H beam in order to be able to easily remove the H-beam used to prevent the soil and ground from collapsing when firming the foundation and basement during construction or civil works In particular, since the H beam itself is not firmly supported on the weak part of the ground including the shore, it is usually very difficult to extract the H beam after construction as various hardeners including cement mortar are used. When the coating is installed on the H beam, the coating agent can be easily pulled out as it lubricates between the cement mortar and the H beam.

As described above, in the present invention, a paraffin wax, a solid lubricant, and light oil and silicon are mixed and melt mixed at a high temperature to prepare a coating agent, which is coated on an H-beam surface and solidified at room temperature, and then the ground collapses in a soft ground. It is a very useful invention that can be pulled out H beam very quickly and easily because the encapsulant lubricates when the H beam is pulled out after completion of construction by fixing it in the ground together with cement mortar to prevent the back.
