Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to stone-clad walls using stone-clad metal fittings, prefabricated stone-clad wall members, methods for installing stone slabs, and methods for manufacturing prefabricated stone-clad wall members. The present invention relates to a method for installing stone slabs on the wall of a building, a prefabricated stone wall member used for installing on the wall of a building, and a method for manufacturing the same.

0001

[Prior Art] Conventionally, when installing stone slabs on buildings, etc., a steel frame is installed on an existing concrete wall, and then the stone slabs are pasted on top of the structure. There is a method of filling mortar all over the back of the stones after connecting them (toro method). In this construction method, mortar is generally filled in several times, so
The construction period is long and the surface is prone to staining due to efflorescence. In addition, as for the obitoro construction method, the method of fixing the stone plates to the structure and connecting the stone plates to each other is the same as the method described above, but the backfilling part is about 10 cm above and below the horizontal joint, and the remaining part is left hollow. However, compared to the total pouring method, the degree of fixation of the stone is smaller, and the upper layer cannot be stacked until the mortar has solidified, resulting in efflorescence. As a dry construction method, there is a method in which the stone slab itself is fixed to the structure using hardware such as angles or plates without using backfill mortar at all. In this method, all of the weight of the stone is supported by the metal fittings, so stress can be concentrated around the dowel due to the deformation of the structure, and the durability of the metal fittings to withstand this stress must be considered. The metal fittings required are dowels to connect the stone slabs to each other and triggers for fixing the stone slabs to horizontal reinforcements or dug-in anchors installed in the concrete wall. Furthermore, lightweight foamed concrete is usually used as an exterior material;
When exposed to wind and rain, it deteriorates quickly and its appearance deteriorates.
Spraying on damaged surfaces was not appropriate and it was difficult to regenerate them. In particular, in recent years, building exteriors have become more luxurious and more budgets are being spent, and many owners wish to revitalize their aging and shabby exteriors. When installing tiles on lightweight foam concrete exterior walls, the adhesive between the lightweight foam concrete and the tile adhesive mortar is not perfect.
The tiles were peeling off and many problems with the construction method were pointed out. In addition, when installing stone slabs on an existing lightweight foam concrete exterior wall, the adhesion between the lightweight foam concrete and the adhesive mortar is not perfect, and the lightweight foam concrete itself does not have the durability to support the stone slabs. It was difficult to attach stone slabs to lightweight foam concrete walls.

To provide a stone slab wall using metal fittings for laying stone slabs that can be connected, and a construction method by which stone laying work can be easily carried out on a newly built or existing wall by using the metal fittings, and the construction period can be greatly shortened. There is a particular thing.
