BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel construction method for fastening a ceramic building board to a foundation of a building, and a material for fastening a ceramic building board which enables such a fastening method. It relates to a fastening device.

[0002]

2. Description of the Related Art In general, when a ceramic building plate called siding is fastened to a building, wood or steel is used to assemble a vertical body edge or a horizontal body edge in advance as a foundation set. The building board is directly struck and fixed by using a set screw or a nail, or a fastener is fastened and fixed to a base, and the building board is engaged through the fastener.
As the vertical torso, use channel steel (channel material) with mounting holes for fastening fasteners, and use it as pillars, studs,
Alternatively, there is also known a method of attaching to a wall panel, attaching a fastener to the channel steel using the attachment holes, and using the fastener to fasten a ceramic building board to the foundation of the building (Japanese Patent Laid-Open No. Hei 9-144272). JP, JP-A-10-208
No. 7, etc.).

[0003]

In the case of a wooden substrate, the work of assembling the substrate as a set is easy, and the work of fastening the building board is easy, but since the material is wood, the wood itself is used. Inherent problems such as difficulty in maintaining a high dimensional system, variations in quality due to the location of joints and the presence of cracks, susceptibility to rotting in a humid environment for a long time, insect damage It is difficult to completely avoid such problems as being susceptible to such problems.

[0004] In the case of a steel base material, the above-mentioned inconveniences can be avoided, but special screws (such as screws with a reamer) are prepared to fix the building board or the fastener to the reinforcing steel. Special tools are also required for screw driving, and fastening work is not easy. When renovating an existing building, for example, when attaching a ceramic building board to a wall such as a mortar base, it is easy to properly use the building base set as a fastening member for the building board. In addition, even when the building board is directly struck and fixed to the mortar base, or when the building board is fastened via an appropriate fastener, stable fastening cannot be obtained.

[0005] In the case of constructing a foundation set by hitting and fixing a vertical rim made of channel steel to a pillar or stud or to a wall panel, the structure is not largely influenced by the structure of an existing building. Although it is possible to stably attach the building board to the underground, it is possible to use different sizes of building boards because the grooved steel with mounting holes for fastening the fasteners is used in advance. It is necessary to prepare a dedicated channel steel. Therefore, it cannot be said that the method of construction is highly practical in a place where various construction environments are expected to occur, such as when renovating a building.

[0006] Further, in places such as a window surrounding portion and a joint portion with a lower house, it is necessary to fasten a lower end and an upper end of a building board cut to a predetermined size. In the case of not being able to use effectively, or in the case of fastening construction boards in the case where it is necessary to construct a plurality of construction boards of different dimensions simultaneously,
Conventionally, no measures have been taken against this. The present invention has been made in view of the above circumstances, and it is extremely easy to fasten a ceramic building board of any size, and when the foundation set of an existing building cannot be effectively used. However, an object of the present invention is to provide a method of fastening a ceramic building board, a fastening material, and a fastening fitting thereof, which can extremely easily and stably perform fastening work.

[0007]

If the base material of the building cannot be easily secured, it can be directly attached and fixed to the existing mortar base surface by nailing or the like. In any case, attachment and fixation are easy, and a stable attachment state is obtained.

[0008] The channel steel may be attached vertically as a vertical waist edge, or may be attached horizontally as a horizontal waist edge. Of course, in places such as the window surroundings, both may be attached simultaneously. In the case of mounting as a vertical waist edge, it is preferable to use a fastener that can be fastened and fixed to an arbitrary position of the channel steel using the groove of the channel steel as a fastener, It is preferable to use a fastening block that can move in the groove of the channel steel as a fastening tool.

Since the fastener and the fastening block can move freely in the groove of the channel steel, they are set on the channel steel at an optimum position for fastening the building board to be fastened. be able to. Therefore, regardless of the dimensions of the building board, the optimum fastening state is always easily ensured. Ceramic building boards are fastened to the base of the building using fasteners and fastening blocks, but when fastening using fastening blocks, they can be directly nailed to the fastening blocks with screws or nails. Often, a fastener may be fixed to the fastening block with a screw or a nail, and a ceramic building board may be attached to the fastener.

In the case where the grooved steel as the vertical body edge and the grooved steel as the horizontal body edge material are crossed and assembled, in order to stabilize the assembling as the base set, they are integrally formed using an appropriate mounting bracket. It is desirable to fix. The present invention also provides, as a material for fastening a ceramic building board effectively used in the above fastening method, a first channel steel as a vertical member, a second channel steel as a cross member, A steel base material for fastening a ceramic building board, comprising: a mounting bracket for connecting the second channel steel to the first channel steel in an intersecting manner; and
