Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to hollow extruded materials such as extruded cement plates. For details, please refer to the hollow extrusion Improved to make it easier to bolt the metal fittings used to attach the material to the frame wall etc. Regarding hollow extruded materials.

0002

[Conventional technology]

FIG. 4 shows an example of a hollow extruded material. In Fig. 4, the hollow extruded material 1 is opposite to each other. The main plate portions 2 and 3 are provided with ribs 4 that connect the main plate portions 2 and 3. A plurality of cavities 5 are defined between the main plate parts 2 and 3 by the grooves 4. In addition, if The tube 4 extends in the extrusion molding direction of the hollow extruded material 1 (direction of arrow A in FIG. 4).

0003 When attaching such a hollow extruded material 1 to a wall surface of a building structure, etc., an opening is made in the hollow extruded material 1. 6, and fix the stopper 7 to the hollow extruded material 1 with bolts 8 as shown in Fig. 5. . In order to fix this bolt 8, a receiving metal fitting 1 having a female threaded hole 9 in the cavity 5 is required. 0, and screw the tip of the bolt 8 into this female threaded hole 9. Tighten bolt 8 sufficiently. By fitting, the stopper 7 is fixed to the hollow extruded material 1.

0004

[Problem that the idea aims to solve]

When the bolt 8 is tightened into the female threaded hole 9 of the receiving fitting 10, the receiving fitting 10 is the main If the length of the bolt 8 is not appropriate when placed on the plate part 3, the tip of the bolt 8 may be damaged. It cannot reach screw hole 9. That is, if the bolt 8 is too short, the opening 6 Even if the bolt 8 is inserted into the hole, the tip of the bolt 8 does not reach the female threaded hole 9. On the other hand, bolt 8 If it is too long, the tip will easily reach the female threaded hole 9, but it will pass through the female threaded hole 9. The tip of the bolt 8 hits the main plate 3 on the opposite side, so do not tighten the bolt 8 sufficiently. It cannot be inserted, and the metal fittings rattle.

[0005] Because of this, the state in which the receiving metal fitting 10 is lifted from the main plate part 3 after all It is necessary to place the bolt 8 into the female threaded hole 9 and tighten the bolt 8. be. Therefore, when tightening the bolt 8, support the receiving bracket 10 by hand or with an appropriate tool. This makes bolting work extremely complicated and time-consuming. It had become.

[0006]

[Means to solve the problem]

The hollow extruded material of the present invention has multiple cavities defined by ribs extending in the thickness direction of the board. In the hollow extruded material that is defined by the The feature is that the shelf-like protrusions for locking the fittings are protruded in the direction of approaching each other. That is.

[0007]

[Effect]

In the hollow extruded material of the present invention, the shelf-like protrusion provided in the middle of the rib has a receiving plate. You can leave the metal fittings in place and tighten the bolts in this state. In this case, the receiver The metal fittings are floating away from the main plate, so even if the bolt length is short, Its tip fully reaches the female threaded hole of the receiving metal fitting. Also, the length of the bolt is short enough. Therefore, even if the bolt is tightened sufficiently, its tip will not touch the main plate on the opposite side of the hollow extrusion. I never run into it.

[0008]

【Example】

Examples will be described below with reference to the drawings. Fig. 1 is a perspective view showing a hollow extruded material according to an embodiment of the present invention, Fig. 2 is a side view, and Fig. 2 is a side view. Figure 3 is a cross-sectional view.

[0009] In the hollow extruded material 11 according to this embodiment, the pair of main plate parts 2 and 3 are connected by the ribs 4. The ribs 4 define a plurality of cavities 5. This rib 4 From the opposing surfaces, shelf-like projecting pieces 12 are provided to protrude in a direction toward each other.

0010 Since the shelf-like protruding piece 12 is provided in this way, the receiving metal fitting 10 can be attached to the shelf-like protruding piece 12. It is possible to keep it floating from the lower main plate part 3 by locking it to the main plate part 3 (Fig. 3). reference). Therefore, even if the bolt 8A is short, the female screw hole of the metal fitting 10 to receive the tip of the bolt 9 can be easily reached and screwed in. And the length of bolt 8A is the main plate part Since the distance between 2 and 3 is sufficiently shorter, insert bolt 8A into opening 6 all the way to the base. However, the tip of the bolt 8A does not hit the main plate 3, and the bolt 8A By sufficiently tightening, the stopper 7 can be firmly attached to the hollow extruded material 11. .

[0011] As is clear from FIG. 3, there is a gap between the tips of the shelf-like protrusions 12, The space is large enough for the bolt 8A to be inserted therethrough.

0012

【effect】

As mentioned above, according to the hollow extruded material of the present invention, the shelf-like shape for locking the fasteners can be A projecting piece is provided on the rib, and the receiving metal fitting is fixed to the shelf-like projecting piece. This makes it extremely easy to attach the fasteners for fixing hollow extruded materials with bolts. It becomes possible to Moreover, the bolt for fixing this hollow extruded material is The fitting can be inserted deeply and firmly fixed, and the installation strength of hollow extruded material is will also be improved.
