Design Registration No. 1634802 Gazette

In the prior art shown in FIG. 10, the ends of adjacent tight frames are brought into contact with each other to determine the mounting position. Although there is a slight notch at the end, it was necessary to lengthen the tight frame outward from the point where it was fixed by welding in order to determine the mounting position. However, if it is shortened, it becomes difficult to determine the mounting position of the tight frame, and there is a risk that workability may deteriorate.

The present application is a tight frame in which the mounting positions are determined by aligning the girder positions of the opposite longitudinal ends in adjacent tight frames. The width of the longitudinal end is narrower than the full width of the tight frame. Alternatively, a separate positioning member is integrated and protrudes outward from the longitudinal end of the tight frame.

Further, in the present application, in addition to the above structure, the ridge side at one end and the eaves side at the other end of the longitudinal end of the tight frame are cut out in a substantially hook shape.

Further, in the present application, in addition to the above structure, a positioning instruction portion is formed at the longitudinal end portion of the tight frame or the positioning member end portion.

The tight frame of the present application is simply a tight frame because the width of the longitudinal end is narrower than the total width, or the positioning member, which is a separate body, is integrated and protrudes outward from the longitudinal end. The cost can be kept low rather than extending the length. Further, since the longitudinal end portions of the adjacent tight frames or the positioning members are opposed to each other as in the conventional case and the girder row positions can be aligned, the workability is not deteriorated. Further, since the positioning instruction portion is formed at the longitudinal end portion of the tight frame or the positioning member end portion, the flow direction positions of the adjacent tight frames can be easily aligned with each other.

Further, the tight frame of the present application can be manufactured by overlapping the ends in the longitudinal direction by forming the ridge side at one end in the longitudinal direction and the eaves side at the other end in a substantially hooked shape. .. As a result, the length of the strip-shaped material can be shortened.

First, examples of the tight frame of the present application (Example 1-1) will be described with reference to FIGS. 1 to 4. The tight frame T of this embodiment is used to attach a vertical roofing material such as a folded plate to the roof of a building. The vertical roofing material such as a folded plate attached to the tight frame T of this embodiment has a cross-sectional shape in which peaks and valleys are formed, such as a fitted folded plate, a goby folded plate, and a laminated folded plate. Does not matter. Further, the tight frame T of the present embodiment may have a shape in which a strip-shaped material is bent to form a mountain portion T1 and a valley portion T2, and two or more peaks are formed in one. The tight frame T of this embodiment is fixed on a structural material such as a steel frame by welding. At this time, the vicinity of the portion (fixed portion T21) where the mountain portion T1 is raised from the valley portion T2 of the tight frame T is welded.

In the tight frame T of the present embodiment, the longitudinal end portions T3 and T3 of the adjacent tight frames T and T face each other, and the girder positions are aligned to determine the mounting position. For example, the edges are abutted (contacted) with each other, and the edges of the opposing longitudinal ends are aligned in a straight line. Regardless of whether the tight frame T of this embodiment has a shape in which only one mountain is formed or a shape in which two or more mountains are formed, when the tight frames T are fixed side by side, the formation pitch of the mountain portion T1 is formed. The dimensions are designed to be constant.

The tight frame T1 of this embodiment has a shape in which the ridge side at one end and the eaves side at the other end of the longitudinal end portions T3 and T3 are cut out in a substantially hook shape, and the longitudinal end ends. The width of the portion T3 is narrower than the total width of the tight frame T. Since the longitudinal end portion T3 has such a shape, the material can be separated by the substantially Z-shaped cutting portion T4 without waste. Therefore, as shown in FIG. 4A, the strip-shaped materials can be used by overlapping each other by the length dimension o. Therefore, as shown in FIG. 4B, the conventional technique requires a length dimension L, but the tight frame T of this embodiment requires only a length dimension L', and the strip-shaped material is saved by the length dimension G. can.

When mounting the tight frame T of the present embodiment, the mounting position is determined by the edges of the opposing longitudinal end portions facing each other and the girder row positions being aligned. At this time, the vicinity of the portion (fixed portion T21) where the mountain portion T1 is raised from the valley portion T2 of the tight frame T is welded. Therefore, since the end portion T3 in the longitudinal direction is not used for fixing, even if the width is narrowed, it does not affect the mounting strength of the tight frame T.

The tight frame T of this embodiment may be embossed in order to improve the strength, and the width of the end portion T3 in the longitudinal direction may be narrower than the total width of the tight frame T.

Next, another embodiment of the tight frame of the present application (Example 1-2) will be described with reference to FIGS. 5 to 7. Of the longitudinal end portions T3 and T3, the ridge side at one end and the eaves side at the other end are notched in a substantially hook shape, which is common to the present embodiment and the first embodiment. .. The difference between this embodiment and the first embodiment is that, of the longitudinal end portions T3 and T3, the first contact piece T31 formed on the ridge side from the cut portion T4 on the ridge side at one end, and the other end. It is a point where the second contact piece T32 formed on the eaves side is formed from the cut portion T4 on the eaves side.

By forming the first contact piece T 31 and the second contact piece T 32 as in the present embodiment, when the first contact piece T 31 and the second contact piece T 32 are formed and fixed on a structural material such as a steel frame, the adjacent tight frames T / T are formed. The mounting position in the girder direction can be determined only by abutting (contacting) the edges of the longitudinal ends of the steel frame. That is, one of the adjacent tight frames T and T, the first contact piece T31, is brought into contact with the edge of the longitudinal end portion T3 in which the other second contact piece T32 is formed. It can be easily positioned.

Further, in this embodiment, the positioning instruction portion T33 is formed at the longitudinal end portion T3 of the tight frame T. In this embodiment, in the adjacent tight frames T and T, the position of the ridge-side edge of the other first contact piece T31 or the eaves-side edge of the second contact piece T32 is set on one positioning indicator T33. By matching them, the mounting positions of the tight frames T and T in the flow direction of the roof can be aligned.

The positioning instruction unit T33 may be a notch or marking as shown in FIG. 10, or may be a marking or the like. Further, the mounting structure may be such that the positioning instruction portions T33 and T33 of the adjacent tight frames are aligned with each other.

The tight frame T of the present embodiment has a shape in which the ridge side at one end and the eaves side at the other end of the longitudinal end portions T3 and T3 are cut out in a substantially hook shape, and the longitudinal end is formed. The width of the portion T3 is narrower than the total width of the tight frame T. By forming such an end portion, the strip-shaped material can be separated by the substantially Z-shaped cutting portion T4 without waste. Therefore, as in the case of Example 1-1 shown in FIG. 4, the strip-shaped materials can be used by overlapping in the longitudinal direction. Therefore, the length of the strip-shaped material can be saved.

The tight frame T of this embodiment may also be embossed in order to improve the strength, and the width of the end portion T3 in the longitudinal direction may be narrower than the total width of the tight frame T.

Next, another embodiment of the tight frame of the present application (Examples 1-3, 1-4, 1-5) will be described with reference to FIG. Of the longitudinal end portions T3 and T3, the ridge side at one end and the eaves side at the other end have a shape cut out in a substantially hook shape in Examples 1-1 and 1-2. It is common. The feature of the embodiment (Example 1-3) shown in FIG. 8A is that the cut portion T4 has a substantially Z-shape formed by a straight line. The feature of the examples (Examples 1-4 and 1-5) shown in FIGS. 8 (b) and 8 (c) is that the cut portion T4 includes a curve. These examples are also included in the shape notched in a substantially hook shape.

Next, another embodiment of the tight frame of the present application (Example 2) will be described with reference to FIG. In the tight frame T of this embodiment, a positioning member P, which is a separate body, is integrated with the longitudinal end portion T3. (A) is an example in which the positioning member P and the connecting member J are integrated into one tight frame T. (B) is an example in which one long strip-shaped positioning member P is integrated with two tight frames T in one mountain. (C) is an example in which the positioning member P is integrated with both the longitudinal end portions T3 and T3 of the two tight frames T.

The tight frame T of this embodiment may also be embossed in order to improve the strength.

In any of (a), (b), and (c) in this embodiment, a separate thin plate is integrated with the tight frame T as a positioning member P, and protrudes outward from the longitudinal end portion T3 of the tight frame T. There is. The positioning member P, which is a separate body, may have a cross-sectional shape different from that of the tight frame T. For example, it may be thinner, thicker, or wider than the tight frame T. Further, the material such as resin may be different from that of the tight frame T. In addition, the positioning member P may be integrated with the same cross-sectional shape as the tight frame T so as to extend the longitudinal end portion T3 with a material cheaper than the tight frame T.

In this embodiment, since the vicinity of the portion where the mountain portion T1 is raised from the valley portion T2 of the tight frame T (fixed portion T21) is welded, the strength of the positioning member P itself and the positioning member P are integrated with the tight frame T. The increased strength does not affect the mounting strength of the tight frame T at all. Therefore, since the strength of the positioning member P integrated with the tight frame T does not matter, it may be integrated by sticking with an adhesive or double-sided tape.

In this embodiment, when it is fixed on a structural material such as a steel frame, it is attached by abutting (contacting) the ends of the positioning members P / P integrated with the adjacent tight frames T / T. The position is decided. Further, the positioning instruction unit P1 may be formed on the positioning member P. The positioning members P and P integrated into the adjacent tight frames T and T can use the positioning instruction units P1 and P1 to align the mounting positions of the tight frames T and T in the flow direction of the roof.
