[0001]
[Industrial applications]
The present inventionIs outsideRegarding the wall construction method, more specifically, when forming a wall on the outer peripheral surface of a building, it is effective to standardize work procedures on site and build high quality outer wallsExterior wallConcerning the construction method.
[0002]
[Prior art]
Unit wall materials made of ceramic-type board materials such as siding boards supplied as standard products are not only excellent in fire resistance and durability, but also can exert favorable modeling effects in appearance design, Recently, it has come to be used as an outer wall material of buildings.
[0003]
By the way, when a unit wall material made of ceramic board such as siding board is used as an outer wall material of a building, it is usually necessary to adjust the dimensions at the construction site and use it as it is on the wall part where standard products can be installed immediately. However, unnecessary portions were cut off from the wall portions that cannot be attached because they were too large to be used as standard products.
[0004]
However, in the case of the above-mentioned construction method, it is necessary to adjust the dimensions at the construction site, which is troublesome in terms of work. However, there is a drawback that the processing cost for discarding this is separately required.
[0005]
Also, as a method of solving such disadvantages, it is necessary to consider the relationship with the wall to be formed on the building before transporting the outer wall material as a unit wall material, which is a standard product, to the building site. Some of the pre-cut materials are precut to the desired size at the factory, and the outer wall material prepared as this pre-cut wall material is carried into the building site together with the outer wall material as a standard product, attached to the building, and the remaining material Exterior wall construction methods that minimize the occurrence have already been proposed.
[0006]
Moreover, in this case, the outer wall material as a unit wall material, which is a standard specification product, and the outer wall material as a pre-cut wall material are transported to the building site in a mixed state, so that each outer wall material is On the back surface side, an identification code indicating an individual wall surface portion to be allocated when forming a wall surface is attached, and each of the outer wall materials is sorted by the identification code so that the outer wall material can be attached to a correct wall position.
[0007]
[Problems to be solved by the invention]
By the way, even with the above-mentioned conventional method, which is performed by attaching an identification code to the back surface of each outer wall material, it is necessary to form the wall surface of the building with the correct positional relationship without generating scrap materials at the building site as residual material. Can.
[0008]
However, in the case of the above-mentioned conventional method, since the identification symbol is attached to the back surface of each outer wall material, when each of the outer wall materials is transported to a building site in a stacked state, it is taken out one by one and the outer wall material is taken out one by one. It is necessary to perform the mounting work while individually checking the identification symbols attached to the back surface side, and there is a disadvantage that it becomes a hindrance factor in improving work efficiency.
[0009]
Furthermore, depending on the accuracy of the building's skeleton, there is a possibility that the outer wall material that does not match the dimensions may come out as the outer wall material is sequentially attached according to the predetermined procedure. There was also a problem that labor was saved.
[0010]
In particular, in a building having an opening such as a window on a wall surface, when a precut wall material is used as an outer wall material around the opening, the precut dimensions may not be matched as a result. Problem that readjustment work for size adjustment in case is complicatedButthere were.
[0011]
In addition, the walls located at the outer corner and the inner corner of the building are portions where the corresponding outer wall materials are abutted with each other, and when a precut wall material is used as an outer wall material at such a corner, the wall is attached. When the wall surfaces are formed, the abutting ends sometimes become irregular, and there is also a disadvantage that an operation for adjusting the ends is required.
[0012]
