- the positioning protrusions 2e, 2e of the contact member 2 enter between the protrusions A2, A3 of the engagement groove A1 and between the protrusions B2, B3 of the engagement groove B1, so that the engagement grooves Al, B1 are formed.
- Positioning of the contact member 2 in the width direction of is performed.
- the first contact member 2 has the blocking plates 2f, 2f of the contact member 2 located at the engagement position.
- the width of the blocking plate portion 2f (the width in the width direction of the engagement grooves Al and B1) is set substantially equal to the interval between the substrate portions 4a. Therefore, when the contact member 2 abuts against one side surface A4, B4 of the structural members A, B, the first and second engagement members 4, 4 'become almost immovable. After that, the screw portion 8a of the bolt 8 is passed through the bolt seat 2d and screwed into the screw hole 6a of the nut 6.
- the positioning members 2e, 2e position the contact member 2 in the width direction of the engagement grooves Al, A2, whereby the axes of the bolt seat 2d and the screw hole 6a are aligned. Therefore, the bolt 8 can be easily screwed into the nut 6. Then, tighten bolt 8. As a result, the structural materials A and B are fixed (see FIG. 10).
- the reverse procedure may be performed. That is, the bolt 8 is loosened and removed from the nut 6. Next, the contact member 2 is removed, and the fixing unit 3 is exposed. Thereafter, the first and second engagement members 4, A 'are moved closer to the through position. Then, the fixing unit 3 is also removed from the structural materials A and B.
- FIG. 11 shows a fixed unit 3 A used in place of the fixed unit 3.
- a holding member 5A is used instead of the holding member 5.
- the holding member 5A is made of an elastic plate material such as spring steel, and the regulating plate portions 5b, 5c are fixed to the substrate portions 4a, 4a of the first and second engaging members 4, 4 '.
- First and second engagement members 4, 4 ' are the first and second engaging portions 4b, 4c of the first engaging member 4 and the first and second engaging portions of the second engaging member 4' due to the elastic deformation of the holding member 5A. It is possible to move between the insertion position indicated by the imaginary line where 4b and 4c abut each other and the maximum separation position indicated by the solid line.
- the holding member 5A is in a natural state with no elastic deformation when the first and second engaging members 4, 4 'are located at the maximum separation position, and the first and second engaging members 4, 4' are in a natural state.
- a ' is located at the through position
- the first and second engagement members 4, 4' are elastically deformed in accordance with the displacement amount to the maximum separating position force insertion position.
- the holding member 5A is also used as an urging means. Note that the relationship between the insertion position and the maximum separation position and the engagement position is set to the same relationship as in the above embodiment.
- the coil spring 7 is unnecessary, so that the manufacturing labor and the number of assembling steps can be reduced by that much, and as a result, the fixed unit 3A Manufacturing cost can be reduced.
- FIG. 12 shows a fixed unit 3 B used in place of the fixed unit 3.
- this fixing unit 3B female threads are provided on the side of the first and second engaging members 4 and 4 'opposite to the top plate 2a (the side where the structural materials A and B are separated from each other; the upper part in FIG. 10).
- One end and the other end of a female screw portion (female screw member) 9 having a hole 9a are provided integrally with the body.
- the first and second engaging members 4 and 4 ' are formed integrally with the female screw portion 9 interposed therebetween.
- the female screw portion 9 corresponds to the nut 6 in the above embodiment, and the bolt 8 is screwed into the female screw hole 9a.
- the board portions 4a, 4a intermediate portions located between the female screw portion 9 and the first and second engaging portions 4b, 4c) of the first and second engaging members 4, A 'are formed thin, As a result, the first engagement portions 4b, 4b (second engagement portions 4c, 4c) of the first and second engagement members 4, 4 'can be elastically deformed in a direction in which the first and second engagement members 4, 4' approach each other.
- the substrate portion 4a is in a natural state where no external force acts on it, the first engagement portion 4b and the second engagement portion 4c are located at the maximum separation positions in the above embodiment.
- the pressing force is also elastically deformable in the substrate portion 4a until the first engagement portions 4b, 4b and the second engagement portions 4c, 4c abut against each other and reach the insertion position. Therefore, the substrate portion 4a can return to the first and second engagement portions 4b and 4c inserted into the engagement grooves Al and B1 to the engagement position by being elastically returned and deformed. from now on As is clear, in this fixed unit 3B, the respective substrate portions 4A, 4A of the first and second engaging members 4, 4 'pass through the first and second engaging portions 4, 4' through the through position force. Also used as biasing means for moving to the engagement position.
- FIG. 13 shows a fixed unit 3 C used in place of the fixed unit 3.
- the fixing unit 3C is obtained by omitting the holding member 5 from the fixing unit 3 described above, and the other configuration is the same as that of the fixing unit 3. Therefore, this fixed unit 3C does not maintain the force assembled state in which the first and second engagement members 4, 4 ', the nut 6, and the coil spring 7 are assembled as a unit. Although it is necessary to maintain the state, the holding member 5 is unnecessary, so that the manufacturing cost of the fixed unit 3C can be reduced accordingly.
- the coil spring 7 When the coil spring 7 is in the natural state, the first and second engaging members 4, ′ are located at the maximum separated positions. By coupling both ends of the coil spring 7 to the first and second engaging members 4 and 4 ', the coil spring 7 can also be used as the holding member 5.
- the fixing device for a structural material according to the present invention can be used for fixing not only rectangular materials such as aluminum but also intersecting flat plates and other various structural materials to each other.
