Description

Exterior insulation construction method for buildings}

The present invention relates to a method for constructing external insulation of a building.

Recently, with the rapid increase in energy consumption, effective management of energy has emerged as a common issue in countries around the world, including Korea.

In particular, a large amount of energy out of the total energy consumption is consumed in the building sector due to problems in thermal management and energy conservation methods of buildings and lack of alternative energy use technology. If energy is saved through exterior wall insulation in the building sector, efficient energy savings can be achieved. It will be achievable.

The building envelope is one of the largest energy loss paths among the various elements that make up a building, and in order to reduce heat loss through the building envelope, not only developed countries but also Korea mandates construction by region and building part, contributing greatly to energy conservation. is doing

However, because energy saving through building insulation cannot be achieved with only legal insulation standards, research on insulation design, construction technology, and insulation methods for each building structure has been continuously conducted.

Currently, many insulation materials used in building walls include polystyrene foam, glass wool, rock wool, urethane foam, perlite, vermiculite, and foamed concrete.

A common construction method using these insulating materials is the internal insulation method, which fills the cavity between the outer wall and the inner wall with an insulating material such as glass wool.

Conventionally, most buildings provide insulation to building walls using the internal insulation method described above. In the case of internal insulation, construction is easier than external insulation, and in addition to the advantage of lower construction costs, the insulation material is easier to protect from external shocks. There is an advantage.

The internal insulation method has a problem in that it cannot prevent the occurrence of thermal bridges. In particular, since heat loss occurs in the winter and heat gain occurs in the summer, the internal insulation structure causes 10 to 15% of heat loss compared to the external insulation.

In addition, condensation is prone to occur in such thermal bridge areas, and after the building is completed, the internal surface temperature of the thermal bridge area decreases, resulting in defects such as mold growth due to condensation. There is a problem in that differences in thermal behavior between insulated and non-insulated parts of the structure occur, which greatly affects durability due to cracks in the external structure.

Recently, as the need for energy-saving buildings has increased, interest in passive houses and zero-energy houses has increased, and interest in external insulation systems has increased accordingly.

However, the construction method of such an external insulation system is more complicated than that of an internal insulation system, so specialized technicians are required due to the nature of the construction method, and the structure does not have a smooth vertical surface, so errors are formed when combining the external insulation structure and the structure. It remains a difficult problem to solve, and in addition, unlike in the past, the thickness of the insulation material forming the external insulation is about 200 to 300 mm thick, so there is a problem that the method of fixing it remains a very difficult problem.

In addition, the conventional external insulation construction method had the problem of generating cracks and making it vulnerable to water leaks because it required installing brackets for fixation on the building wall.

When fixing the insulation panel 500 to the vertical assembly 100, the operator fastens the first rear coupling part 571 or the second rear coupling part 572 through a panel fastening member (not shown). , it can be assembled simply by fitting together other insulation panels and then fastening them together.

In this way, when assembling a plurality of insulation panels 500, the panel upper space 587 and the panel lower space 597 are connected to the left and right, and even if rainwater penetrates inside, the panel upper space 587 and the panel lower space 597 are connected to each other. It has the characteristic of being able to be quickly discharged to the outside through space 597.

The step S20 includes a step of fixing the vertical support frame 130 to the railing (S21), a step of fastening and fixing the vertical support frame 130 and the top frame 400 (S22), and after step S22. It includes a step (S23) of assembling the first vertical frame 110 and the second vertical frame 120 through the connector 300.

The step S30 includes assembling the first connector 301 and the second connector 302 through the horizontal frame 200 to couple the first vertical assembly 101 and the second vertical assembly 102. .

In the detailed description of the present invention, specific embodiments have been described, but of course, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the patent claims described later, but also by the scope of this patent claim and equivalents.
