Description

  The present invention relates to an outer heat insulation method for RC concrete structures.

  Conventionally, as one of the construction methods for RC concrete structures, there is an outer heat insulation method for constructing a heat insulating material on an outer wall surface. Since heat insulation is applied to the outer wall of the building frame, the heat storage inside the building is enhanced, and the temperature fluctuation in the room is reduced throughout the year, thereby reducing energy consumption such as cooling and heating, thereby contributing to energy saving.

  Furthermore, the outer heat insulation method has the advantages that it prevents the occurrence of internal condensation, which is a problem in the inner heat insulation method, suppresses the generation of mold, and increases the thermal efficiency of the air conditioning. In addition, since the building frame does not come into direct contact with the outside air, there is an advantage that the durability of the building frame is improved by greatly reducing adverse effects on the building frame due to hot solar heat in the summer and winter cold damage.

  However, when an RC concrete structure is to be constructed by such an external heat insulation method, until now, after constructing the frame concrete, the heat insulating material is bonded to the outer wall surface of the frame concrete, and a refractory material is applied thereon. A method of fixing to concrete with an anchor or a method of fixing a glass fiber or the like to an outer wall surface of a concrete with an anchor and constructing a refractory mortar on the surface has been performed.

  In this way, in any construction method, it is necessary to perform work manually outside the outer wall, so in areas where urban buildings are densely packed, the gap between neighboring houses is narrow, and the viewpoint of effective use of land Therefore, it was practically impossible to build an RC concrete structure by the external insulation method.

  In view of such a conventional defect, the present invention makes it possible to build an RC concrete structure by an outer heat insulation method even when there is no gap with a neighbor, and further, heat insulation of the outer wall to be constructed outside the outer wall. Since the material has a function as a temporary frame, an external temporary frame is not required, the land can be utilized to the maximum, the construction period is shortened, and an external insulation method that can be easily and inexpensively provided is provided. Is the main issue.

In order to solve such a problem, the invention according to claim 1, in constructing the outer wall temporary frame of the RC concrete building, the slab temporary frame slab to be constructed on the outer side of the building, the outer side is composed of the outer wall finishing material. In addition, while using an outer wall insulating panel provided with an outer backing material on its inner side and further comprising an inner wall made of a heat insulating material, an H-shaped lateral fixing member for sandwiching and fixing the lateral direction of a plurality of outer wall thermal insulating panels includes: An irregular decoration is formed on the outer surface of the T-shaped part facing the outside of the building, and the T-shaped part facing the inner side of the building is C-shaped on the back part so that the T-shaped part can be received. A C-shaped fixed metal with a hole for attaching a separator is attached, and an H-shaped lateral fixing member and a slab temporary frame slab to be installed on the inner side of the outer wall are fixed to the C-shaped fixed metal at regular intervals. When installing the separator for In addition, the outer wall heat insulation panel is sandwiched and fixed vertically by an H-shaped vertical fixing member for sandwiching and fixing the vertical direction of the outer wall heat insulation panel, and the outer surface of the T-shaped portion facing the outside of the building of the H-shaped vertical fixing member is fixed to the outer surface. Form an uneven decoration, the upper part of the T-shaped part is formed diagonally so that the rainwater does not flow into the outer wall insulation panel side, and the lower part flows rainwater into the outer wall insulation panel side So that the upper part of the H-shaped lateral fixing member is pressed down, and the upper and lower tip portions of the T-shaped part facing the inside of the building of the H-shaped vertical fixing member are In order to prevent the vertical fixing member from falling off the concrete on the outer wall, a wall with a cylindrical tip is provided, and a corner outer wall thermal insulation panel built outside the corner of the building is supported to support the inner wall of the outer wall temporary frame. L-shaped steel at corner It was placed, that the L-shaped steel drilled horizontally hole for fixing the C-shaped fixing hardware on the L-shaped steel, to secure the C-shaped fixing hardware and L-shaped steel with a bolt and a nut, the L-shaped steel L A steel plate fixing plate is attached, and a separator for fixing the L-shaped steel material and the slab temporary frame siding plate inside the outer wall is attached to the L-shaped steel material fixing plate. It is characterized in that a dam is constructed , raw concrete is poured into the outer wall temporary frame constructed in this way, and the outer wall heat insulating material and the outer wall concrete are integrally formed.

  According to the first aspect of the present invention, the outer wall heat insulation panel to be constructed on the outside of the building is sandwiched between the H-shaped vertical fixing member and the H-shaped horizontal fixing member, and fixed to be used as a concrete temporary frame outside the building. Therefore, it is not necessary to work on the outside of the building compared to the case where a slab temporary frame slab or slab temporary frame joist is installed on the outside of the RC concrete building as before. When building a building in a land with a high land price, such as an urban area, or in a narrow area, the land can be used effectively, and the labor of removing the temporary frame outside the building can be saved. Shortening and significant cost reduction can be achieved.
