As with the female fitting joint 6 side, the means for forming the rough surface 9a may be a rough surface by rusting treatment or a rough surface by blasting such as shot blasting or sand blasting. .

  The rough surfaces 8a and 9a on the female fitting joint 6 and the male fitting joint 7 may be processed before forming the strip steel plate into the folded plate 1 with a joint. You may give after forming in the attached folded board 1. FIG.

  Next, the folded plates 1 with joints as described above are arranged in parallel, and the male fitting joint 7 and the other female fitting joint 6 in one adjacent folded plate are fitted to each other. The fitting joint structure of the first embodiment will be described with reference to FIG.

In a state where the folded plate 1 with one joint is arranged on a support beam or a support beam, the folded plate 1 with the other joint is placed so as to cover the male fitting joint 7 in the folded plate 1 with one joint from above. The dovetail groove 10 of the female fitting joint 6 is arranged, the rough surface 9a of the male fitting joint 7 in one folded plate 1 with a joint, and the female fitting joint 6 in the other folded plate 1 with a joint.

The fitting state between the joint 6 and the male fitting joint 7 is not particularly specified, and the male fitting joint 7 is placed in the dovetail groove 10 in the female fitting joint 6 as shown in FIG. In addition, the joint is expected to be somewhat elastically deformed in a loose fitting state having a play dimension in the width direction or in a non-free fit state without a play dimension between the female fitting joint 6 and the male fitting joint 7. Any one of the states may be selected as appropriate. The width dimension of the male fitting joint 7 and the width dimension of the inlet portion of the dovetail groove 10 in the female fitting joint 6 are appropriately set by design.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  The difference between the second embodiment shown in FIG. 3 and the first embodiment shown in FIG. 1 is that the form of each female fitting joint 6 and the male fitting joint 7 is different. Differences will be described, and the other configuration is the same as that of the above-described embodiment. Therefore, the same parts are denoted by the same reference numerals and the description thereof is omitted.

  The form shown in FIG. 3 shows a second embodiment of the present invention, in which concave portions 11 and convex portions 12 are alternately spaced in the longitudinal direction of the member on the engaging surface 8 of one female fitting joint 6. And an engagement surface 9 of the other male fitting joint 7 and a recess 11 of the engagement surface 8 of the one female fitting joint 6. Deviations are provided in the positions corresponding to the protrusions 13 in the corresponding positions, and in the positions corresponding to the protrusions 12 of the engagement surface 8 of the one female fitting joint 6 in the longitudinal direction of the member. It is the folded plate 1 with a joint of the form which has a stop mechanism.

  FIG. 4 shows a state in which the folded plates 1 with joints as described above are juxtaposed so that the female fitting joint 6 and the male fitting joint 7 are engaged with each other. The state is shown.

  As shown in FIG. 6A, the concave portion 11 and the convex portion 12 of the female fitting joint 6 and the convex portion 13 and the concave portion 14 of the male fitting joint 7 Alternatingly spaced in the direction. And while the convex part 13 in the male type fitting joint 7 has entered between the convex parts 12 in the female type fitting joint 6, in the lateral direction, it is in contact with or slightly separated in the member longitudinal direction and the member width direction. (In the case of illustration) The position of each convex part and a recessed part is set.

  Further, as shown in the figure, when the concave portion 11 of the female fitting joint 6 has a truncated pyramid-shaped inclined surface that gradually narrows in the depth direction, or the convex portion of the male fitting joint 7. When 13 includes a truncated pyramid-shaped inclined surface, the inclined surface can be guided and engaged at the time of fitting, and the fitting joint can be arranged at a predetermined position.

  A plurality of the concave portions 11 and the convex portions 12 of the female fitting joint 6 may be provided at intervals in the member width direction. According to this, the convex portion 13 on the male fitting joint 7 side is provided. And the recess 14 may be set.

  In FIG. 6B, the truncated pyramid-shaped (frustum pyramid-shaped) recess 11 of the female fitting joint 6 as described above is formed in the truncated pyramid-shaped (frustum-pyramidal shape) of the male fitting joint 7. A plan view of the joint portion in a state where the convex portion 13 is fitted and the truncated pyramid-shaped convex portion 12 of the female fitting joint 6 is fitted in the truncated pyramid-shaped concave portion 14 of the male fitting joint 7 is shown. Has been. Although it is preferable in terms of performance that the concave portions 11 (14) and the convex portions 13 (12) facing each other are in close contact with each other, the workability of fitting and joining can be improved if they are slightly separated. As described above, when a shearing force is applied in the longitudinal direction of the joint fitting portion J even in a slightly separated state, one of the adjacent folded plates 1 with a joint moves slightly in the longitudinal direction of the member. Thus, the concave portion 11 (14) and the convex portion 13 (12) are in close contact with each other, and displacement in the longitudinal direction of the member can be prevented.

FIG. 6C is an explanatory view of another embodiment, and instead of the truncated pyramid-shaped concave portion 11 and convex portion 12 of the female fitting joint 6 as described above, an elliptical truncated cone shape (a truncated elliptical shape) is shown. The conical concave portion 11 and the convex portion 12 may be provided by pressing, rolling, or the like, and instead of the truncated pyramidal convex portion 13 and the concave portion 14 of the male fitting joint 7, an elliptical frustum shape The convex portion 13 and the concave portion 14 may be provided by press working or roll processing, and these may be fitted. By making the concavities and convexities elliptical in this way, when the folded plate with a joint is engaged from the width direction, until the fitting at the side edge of the folded plate is completely completed, the opposing female fitting The concave portion 11 (14) and the convex portion 13 (12) provided on the engaging surfaces of the joint 6 and the male fitting joint 7 are in a loosely fitted state, so that the fitting operation can be efficiently performed and the fitting is performed. In a state in which the concave portion 11 (14) and the convex portion 13 (12) are in close contact with each other, the displacement in the longitudinal direction of the member at the fitting portion can be reliably prevented.
Here, the oval shape is shown as an example. However, the side surfaces of the concave portion and the convex portion have an angle with respect to the moving direction of the fitting joint at the time of fitting joining, which is the width direction of the folded plate perpendicular to the longitudinal direction of the member. Similar effects can be obtained even with a trapezoidal shape.
These recesses or protrusions can have various forms, and the unevenness of the female fitting joint 6 and the unevenness on the male fitting joint 7 side may be reversed. Further, as shown in the figure, they may be arranged in series at intervals, or may be arranged in a staggered manner (not shown).

FIGS. 7 and 8 show a third embodiment of the present invention. In this embodiment, the engagement surface 8 in the female fitting joint 6 and the engagement surface 9 in the male fitting joint 7 are as follows. This is a form in which adhesive layers 8b and 9b continuous in the longitudinal direction of the member are formed to serve as a displacement prevention mechanism. The adhesive layers 8b and 9b may be provided on at least one of the female fitting joint 6 and the male fitting joint 7.
Further, in this way, the adhesive layer 8b may be provided on the engaging surface 8 of the female fitting joint 6 having the concave portion 11 or the convex portion 12 in the embodiment, or the convex portion 13 or the concave portion 14 is provided. You may make it provide in the engagement surface 9 in the male type fitting joint 7 which has.

  As an adhesive for forming the adhesive layers 8b and 9b, for example, an epoxy adhesive, an acrylic adhesive, a urethane adhesive, a silicon adhesive, or the like can be used. Moreover, you may use an adhesive with high adhesive force as an adhesive agent. Although not shown in the figure, adhesive may be applied just before fitting construction or the gap after fitting construction may be filled with adhesive. It is also possible to adopt a form in which the release paper is peeled off immediately before construction, attached to 8,9.

  In consideration of joining the female fitting joint 6 and the male fitting joint 7 using an adhesive as described above, the female fitting joint 6 and the plate of the male fitting joint 7 are used. The clearance is preferably about 0 to 5 mm.

9 and 10 show a folded plate 1 with a joint according to a fourth embodiment of the present invention. In this embodiment, the folded plate 1 is so formed as to be inclined downward integrally with the upper surface plate 7b of the male fitting joint 7. The supporting pressure ribs 15 for projecting are provided integrally and continuously in the longitudinal direction of the member as a displacement preventing mechanism.
The support ribs 15 in the male fitting joint 7 as described above are engaged so as to press the inclined inner side surface plate 6a in the female fitting joint 6 so that the upper surface plate 7b in the male fitting joint 7 is female. The inclined side plate 7a of the male fitting joint 7 is pressed against the engaging surface of the inner surface of the inclined outer surface plate 6c of the female fitting joint 6 by pressing against the engaging surface of the upper surface plate 6b of the die fitting joint 6. By pressing, the direct stress of these engaging surfaces is increased, and accordingly, the frictional resistance between the engaging surfaces is also increased, and the displacement resistance in the member longitudinal direction of the fitting portion is increased.

  Further, the bearing rib 15 engages with the inclined inner side surface plate 6 a in the female fitting joint 6, and the inclined side surface plate 7 a in the male fitting joint 7 is inclined with the inclined outer side plate 6 c in the female fitting joint 6. The folded plates 1 with joints are prevented from shifting in a direction in which the folded plates 1 with joints are separated from each other in the fitting portion width direction.

As shown in the drawing, when the supporting rib 15 is integrally bent and connected to the upper surface plate 7b, the folded plate 1 with a joint having the supporting rib 15 can be manufactured at low cost. As the support rib 15, a separate member may be fixed by welding, adhesion, or the like. The support rib 15 is provided on the female fitting joint 6 side, and the receiving portion is provided on the male fitting joint 7. Even if it provides, the bearing rib 15 is provided in the male fitting joint 7, and the receiving part may be provided in the female fitting joint 6.
In other words, at least one of the fitting joints 6 (7) is pressed against the other fitting joint 7 (6) to increase the direct stress (surface normal stress) between the joint surfaces in the joint fitting portion J. A misalignment stop mechanism composed of the pressure rib 15 may be provided.
As described above, the support rib 15 is for firmly pressing the engagement surface 8 of the female fitting joint 6 to significantly increase the direct stress. The shorter the plate, the higher the bending rigidity of the plate, the higher the tensile force, the higher the direct stress, and the higher the displacement resistance. On the other hand, if the width dimension of the bearing rib 15 is increased, the bending rigidity of the plate is lowered and the displacement resistance is also lowered, but the workability of fitting and joining is improved. Further, if the inclination angle γ1 of the bearing rib 15 is increased, the difference “γ1−γ2” between the inclination angle γ2 after fitting determined by the shape dimensions of the male fitting joint 7 and the female fitting joint 6 is increased. Thus, the pressing force generated by elastic deformation or elasto-plastic deformation of the supporting rib is increased, and the displacement resistance is also increased. On the contrary, if the inclination angle γ1 of the bearing rib 15 is reduced, the pressing force is lowered and the displacement resistance is lowered, but the workability of the fitting and joining is improved. The width dimension cm and the inclination angle γ1 of the bearing rib 15 may be determined by design in consideration of such conflicting effects.

  In addition to this embodiment, such a pressure-supporting rib 15 can be applied to the first embodiment or other embodiments, and is a fitting that has been subjected to the friction treatment in the first embodiment. Either the joining structure or the form in which the convex part 13 (12) of the fitting joint 7 (6) is engaged with the concave part 11 (14) of the fitting joint 6 (7), or the form in which the adhesive layers 8b and 9b are provided. In this way, when a plurality of means for increasing the displacement resistance in the longitudinal direction of the fitting portion are provided, the shear resistance in the longitudinal direction of the fitting portion can be more reliably increased, Become.
