  By the way, the upper goby part and the lower goze part of a general folded plate type building material have a small diameter of about 20 mm in height and about 30 mm in width, and in order to accurately engage them, the shape is high over the entire length in the length direction. Precision is required. In addition, folded plate-type building materials are often produced by roll forming at a factory or a construction site using a length of 10 m or more, and are manufactured using many lots of steel plates having different production times. For this reason, even folded plate type building materials produced with the same specifications have different specifications such as surface treatment and mechanical properties, which have a significant effect on shape accuracy in the length direction, and are subject to deformation such as warping and twisting. Could occur.

  Furthermore, when the adjacent folded plate-type building materials are joined together, there is also a problem that if they are lifted by human power or heavy machinery, the entire folded plate-type building material is bent by its own weight.

  For this reason, with conventional folded-plate building materials, it may be difficult to accurately connect seams at the time of construction. Even if they can be engaged, they may be incomplete or fastened with an auxiliary fixing tool such as a screw. Therefore, there are problems such as deterioration of structural performance and fire resistance, and increase of construction cost.

  In addition, as shown in FIG. 2, when the goby joint between the upper goby portion 14 and the lower gouge portion 15 of the folded plate type building material is performed via the inclined side portion, the upper and lower goze portions 14, Even if 15 has a goby joint structure that does not require a fixing tool such as a screw, the goose joint part may fall off due to the force 17 that tries to slide down the upper goby part 14.

  Therefore, the purpose of the development of the folded-plate type building material according to the present invention is to create a folded-plate type building material having a good fire resistance and workability without being loosened or disengaged, with the state of engagement of the seam joint being firm. It is to provide.

The present invention developed in order to solve the above-described problems of the prior art is based on a side edge of a corrugated rectangular metal plate in which peaks and valleys are alternately formed in the plate width direction. goby portion is formed, consists of those above goby portion is formed along the other side edge, through these lower-upper goby section, Ri greens so as to connect the metal plates to each other, the both the lower-upper goby portion was bent in rectangular in turn, in folded-plate-type building materials shaped ing a substantially rectangular winding goby structure, the upper goby portion constitutes the valleys of the metal plate The bottom plate is bent at the extending position of the bottom plate, and is bent upward from the free end portion of the bottom plate, and is folded horizontally outward from the upper end of the rising side portion. An outwardly bent upper side portion, and a falling edge formed by bending approximately 90 ° downward from the tip of the upper side portion Part and an inwardly lower side part that is folded back approximately 90 ° inward in the horizontal direction from the lower end of the falling side part, and the cross-sectional shape is a square spiral shape, the lower goby part is A rising side portion bent at an extended position of the bottom plate constituting the valley portion of the metal plate, and bent upward at approximately 90 ° from the free end portion of the bottom plate; It consists of an inward upper side that is bent approximately 90 ° inward in the horizontal direction from the upper end of the side, and a falling side that is bent approximately 90 ° downward from the tip of the upper side. And the cross-sectional shape is a square spiral shape, and the upper goby portion and the lower goze portion are the upper side outward upper side and the lower side inward upper side that are these components, and the upper goby falling In the state where the side and the lower goby falling side are completed Together in contact phases have, it is an gist constituting the folded plate type building materials, characterized in Rukoto engaged to bite each other.

(2) and the lower goby bottom plate width direction length a and the upper goby outward upper portion widthwise length b of the, a <b in relation near Rukoto,
However , a more preferable solution can be provided.

  In the present invention, the lower goby portion and the upper goby portion are each formed into a square gond structure in which the cross-sectional shape is formed into a square inner winding, thereby forming the lower gob portion and the upper goby portion. The number of the parts (plate elements) is larger than that of the conventional one, and accordingly, the rigidity is improved, and it is expected that the deformation such as warping and twisting hardly occurs at the seam joint part. Therefore, a fixing tool such as a screw is not required for mounting the building material, and easy and reliable construction can be performed and construction cost can be reduced.

  Further, in the present invention, since the lower goby portion and the upper goby portion both have a shape that is bent into a rectangular inner winding, the upper gouge portion and the lower goze portion are in the upper side when the goat joint is completed. In the two orthogonal directions of the part and the falling side part, they are in contact with each other side by side, and are tightly engaged so that they can be firmly engaged, and the gouge joint part is prevented from falling off upward and downward, Has good structural performance.

  Furthermore, in the present invention, when the lower goby portion and the upper goby portion are joined together, the lower end of the lower goby falling side portion and the upper goze inward lower side portion are in contact with each other (to exhibit an inverted T shape) ), The load from the lower goby part (lower gobe side falling side part) can be received in an even distribution in the upper goze inward lower side part provided in the horizontal direction of the upper goby part. Thus, the engagement portion does not slide down and fall off upward or downward as in the conventional case, and a more robust gouge joint can be engaged.

  In the present invention, the width direction length a of the lower goby bottom plate (metal plate valley portion) and the width direction length b of the upper gob upper side portion are such that a <b, When engaging the upper goby part, always use the side of the metal plate crest connected to the lower gore part as a guide, while sliding the upper goby part diagonally along this ridge side, Since it can be dropped onto the lower goby part, the construction can be easily performed even if there is some deformation in the upper and lower goby parts.

  The folded plate-type building material of the present invention is characterized by the cross-sectional shape of the upper and lower goby parts, both of which have a square goby structure with a square cross-section that is bent into a square inner winding (on the main plate portion side). It is what. Therefore, when connecting folded plate type building materials having such upper and lower goby parts, the upper and lower goby parts, that is, the inner winding portions of the squares are in contact with each other and engage with each other. Has an effect that the goby joints are not easily dropped upward or downward.

  Furthermore, in the present invention, the lower goby part has three plate side elements (rising side part, inward upper side part, falling side part), and the upper goze part has four plate side part elements (rising side part, outward upper side part, Since there are more plate side elements than in the prior art, the engaging part when these are joined together becomes firm and high rigidity is obtained. Therefore, there is no warping or twisting in the seam joints, and the effect of eliminating the need to use a fastener such as a screw when mounting the building material can be expected.

  Further, in the present invention, it is preferable to engage the lower goby portion and the upper goze portion so that the lower end of the lower goby falling side portion and the upper goby lower side portion are in contact (so as to exhibit an inverted T shape), As a result, the load of the lower goby part is supported by the uniform distribution of the lower inward side of the upper goby that is bent in the horizontal direction, and the lower goze part does not slide down diagonally.
