Description

The present invention relates to an outer wall mounting method in which a heat insulating material and a multi-faceted stainless steel plate are attached to the outside of the ALC plate material of the outer wall.

On the outer wall surface made of the conventional ALC plate material, a plurality of ALC plate materials are arranged side by side, and a dry joint material such as rubber or a wet joint material such as caulking is placed at the joint between the adjacent ALC plate materials and the ALC plate materials. After loading, the surface of the ALC plate has been painted.

When constructing the outer wall of a general steel-framed building with ALC plate material, steel columns were assembled with a crane, etc., deck plates, etc. were attached to the floor of each floor, concrete was cast, and scaffolding was installed outside the building. After that, the ALC plate material is fixed to the steel pillars, beams, etc., and the joint between the adjacent ALC plate material and the ALC plate material is loaded with a dry joint material such as rubber or a wet joint material such as coking from the outside of the building. Further, the surface of the ALC plate material has been coated.

In this way, on the outside of the building under construction, a dry joint material such as rubber or a wet joint material such as caulking is loaded into the joint between the adjacent ALC plate material and the ALC plate material, and the surface of the ALC plate material is painted. Because it is necessary to install a scaffold for workers to work on the outside of the building, there is a space of about 40 cm or more for scaffold construction between the adjacent land and the building to be built. Because it was necessary, there was a problem from the viewpoint of effective use of land in a small area where buildings in urban areas were densely packed.

Therefore, when constructing the outer wall of a steel-framed building that maximizes the building coverage ratio with ALC board in such a narrow area in an urban area (the gap between the adjacent building and the building to be built is 10 cm to 15 cm). In the case of.) Since it is not possible to install a scaffold on the outside of the building, the outer wall is constructed using the ALC plate material that has been painted on the surface of the ALC plate material in advance at a factory, etc., and the joint between the adjacent ALC panels is constructed. A dry joint material such as rubber or a wet joint material such as caulking has been loaded from the indoor side (the joint on the outside of the building between the adjacent ALC plate material and the ALC plate material is a dry joint material such as rubber or caulking or the like. Since the wet joint material is not loaded), the joints on the outer surface of the building are not waterproofed, so there remains a problem in terms of rainwater intrusion.

Furthermore, when a building is built by the above-mentioned method, the gap between the building and the neighboring building is narrow and it is not possible for workers to enter and maintain the ALC board on the outer wall. Problems such as rainwater entering the building occurred.

In view of such conventional drawbacks, the present invention makes it possible to construct a building using ALC plate material even when the gap between the neighboring building and the newly constructed building is narrow, and the outer wall can be constructed for a longer period of time. The main subject is to provide an outer wall mounting method for ALC plate materials using stainless steel plates that do not require maintenance.

In order to solve such a problem, the invention according to claim 1 fixes a drainage pedestal for an external heat insulating material having a cross-sectional shape generally in the shape of a ladle and a tip in a T shape on the upper surface of the floor slab end of the building. , A stainless decorative steel plate formed in a multifaceted shape is placed on the outer side of the upper chamber of the drainage pedestal for the outer heat insulating material, and a heat insulating panel in which a foamed styrol panel is sandwiched between two veneer plates is arranged on the indoor side of the stainless decorative steel plate. In order to fix the stainless decorative steel plate and the heat insulating panel to the ALC plate material arranged on the indoor side of the heat insulating panel, the joint portions formed on both ends of the adjacent stainless decorative steel plates are overlapped, and the stainless steel plate is generally L-shaped on the joint portion. One end of the ALC plate material fixing metal fitting formed in the above is hooked, and the other end is fixed to the indoor surface of the ALC plate material with a screw.

In the invention according to claim 2, in addition to the structure according to claim 1, the drainage pedestal for the external heat insulating material is formed into a substantially L-shaped upper stainless decorative steel plate L-shaped pressing member and a substantially Z-shaped draining pedestal. The upper and lower surfaces of the lower stainless steel decorative steel plate Z-shaped presser members were fixed to each other by welding, and the L-shaped floor slab fixing member formed into an approximately L shape was fixed to the side surface of the lower stainless steel decorative steel plate Z-shaped presser member by welding. It is a feature.

In the invention according to claim 3, in addition to the structure according to claim 1 or 2, since the engaging portions formed on both ends of the adjacent stainless decorative steel sheets are overlapped and integrated, both ends of the stainless decorative steel sheet are generally cassotte. It is characterized by being bent in the same direction in shape.

In the invention according to claim 4, in addition to the structure according to any one of claims 1 to 3, the ALC plate material fixing bracket has a rectangular stainless steel plate having one end bent into a substantially fishing needle shape and the other end having an L shape. The back part of the hooking member bent into an L shape and the veneer plate holding member bent into an L shape are fixed to each other by welding, and one end of the rectangular stainless steel plate is bent into an L shape and the other end is the corner of the ALC plate material.
