≪ Example 1 >

As shown in FIGS. 1 and 2, the clamp 10, which can connect building materials of various structures according to the present embodiment, is configured to move in a direction to be converged with respect to each other, And first and second fastening portions (13, 14) formed respectively at opposed portions of fastening openings (11, 12) and first fastening openings (11, 12) for clamping building materials, Each of the two latching portions 13 and 14 has a structure in which the clamping portions (grooves, protrusions) formed on the building material are different from each other, Two or more stopping jaws 13a, 13b, 14a, 14b (two are shown as an example) are configured so as to be stepped with each other to clamp the material.

The first tightening tool 11 is a plate member and has a plate-like or box-like or angled (inverted T-shaped cross-section) connecting portion 15 extending from the first fastening portion 13 And the second tightening tool 12 is connected to the connecting portion 15 such that the second tightening tool 12 can be moved forward or backwardly toward the first tightening tool 11. [

Therefore, a nut-shaped socket 16 for forward and backward movement of the second tightening tool 12 is formed in the connecting portion 15.

The second tightening tool 12 is fixed to a bolt-type forward and backward operation rod 17 having a screw thread on the outer circumferential surface thereof and the forward and backward operation rod 17 is screwed to the nut-shaped socket 16 of the connecting portion 15 And the second fastening port 12 is moved forward and backward. The forward / backward operation rod 17 has a gripping head for a convenient operation feeling, so that the forward / backward operation rod 17 can be a ready-made bolt. When the forward and backward operation rods 17 are moved forward and backward by screwing, the position of the second tightening tool 12 is not changed until the rotational force is applied, so that the building material is firmly clamped.

The first tightening tool 11 may have a plate shape and the second tightening tool 12 may have a cylindrical shape. Of course, the first and second tightening tools 11 and 12 may be formed in a plate shape or a cylindrical shape. That is, the first and second fastening openings 11 and 12 can be formed in either a plate shape or a cylindrical shape.

The plate-type can be fitted to both circular or rectangular grooves or holes when the clamp connection portion of the building material is a plate-shaped groove or hole, and the cylindrical shape can be inserted into a circular or square groove or hole when the clamp connection portion of the building material is circular, So that the building material can be fixed.

For example, FIG. 5 shows a structure in which the second tightening tool 12 has grooves, and the second engaging portions 14c and 14d of the second tightening tool 12 have grooves of different sizes.

The clamping structure of the building material by the first locking part 13 and the second locking part 14 is as follows.

Fig. 3 shows a construction in which the building material 1 is clamped by the relatively small first hooks 13a and 14a. Fig. 4 shows the second hooking jaws 13b and 14b, which are relatively large in size, (2). That is, the building materials 1 and 2 have different sizes of the clamp connecting portions, for example, the fixing grooves 1a and 2a. In the case of the fixing grooves 1a having a small size, they are caught by the first locking projections 13a and 14a, (1) is firmly clamped, and in the case of a large-size fixing groove (2a), it is caught by the second latching jaws (13b, 14b) and the building material (2) is tightly clamped.

Up to now, it has been described that the clamp 10 of this embodiment is fixed to the building material or clamped to two or more building materials by means of the first and second fasteners 11 and 12, Nuts or bolts may be applied to bond.

Only the nuts 18 are shown in the drawing, and the nuts 18 are formed on the bottom portion and left and right side wall portions of the clamp 10, for example. The nut 18 is used for fixing the saddle for fixing the reinforcing member.

The first and second fastening openings 11 and 12 can be separated from each other by screw fastening or the like, and thus have a merit of clamping various building materials through a single kind of clamp by replacing them with the shape of the building material .

2 shows a state in which each tubular building material 1 is clamped. Fig. 6 shows a state in which two building materials 1 and 2 are clamped with aluminum foam-type building material 1 and a building material 2 having a profile. to be. It can be seen that the aluminum foam-type building material 1 and the building material 2 having a profile are clamped by the first and second fasteners 11 and 12 even though the structure of the clamp connection is different.

≪ Example 2 >
