Description

[Detailed explanation of the idea] The present invention relates to the shape of hollow extrusions.

Conventional solid or hollow extruded materials have been joined using adhesives or processed into a splintered state when the width was too small due to layout during construction. Further, extruded materials whose ends are damaged during transportation require a lot of effort to repair and reuse. For this reason, especially in the former case, most of it is discarded, resulting in a lot of wasted resources.

The present invention eliminates the above-mentioned drawbacks, reduces the loss rate of the extruded material, makes it easy to use even small-width products and products with damaged edges, and provides a hollow extruded material that saves resources and saves time and effort in construction. With the goal.

In order to achieve this objective, the configuration of the present invention is as follows. In other words, the rectangular parallelepiped main body, which is long in the extrusion direction, has a rectangular cross-sectional shape perpendicular to the extrusion direction, and one and the other short side side surfaces forming one and the other short sides in the cross section perpendicular to the extrusion direction, and one and the other long sides. A plane that is composed of one and the other long side surfaces formed with the sides and both end surfaces corresponding to the extrusion opening, and in which one or more hollow portions penetrating the both end surfaces along the extrusion direction are parallel to the long side surfaces. In the hollow extruded materials arranged in parallel at intervals, a long outer convex strip is formed on the one short side surface along the extrusion direction, and a long outer convex strip is formed on the other short side side surface along the extrusion direction. An outer groove into which the groove can fit is formed, and an inner groove and an inner groove that have the same shape and the same direction as the outer groove and the outer groove are formed in the hollow part. Long cutting grooves are provided along the extrusion direction on the long side surfaces on the virtual extension surfaces of the base surfaces on both sides of the inner groove and on both sides of the inner groove.

An embodiment of the present invention will be described below based on the drawings.

In Fig. 1, the present invention is a hollow extruded material used as a heat insulating material for walls, floors, ceilings, etc., whose main raw material is cement, etc., and whose cross section is rectangular at right angles to the extrusion direction. An outer protrusion 11 that is long along the extrusion direction is formed on one short side 1 of the cross section, and the outer protrusion 11 that is long along the extrusion direction can be fitted to the other short side 2 of the right-angled cross section. An outer concave line 21 is formed. Further, in the main body A, a plurality of hollow parts 3, 4, 5 (in three stages in the embodiment) penetrating along the extrusion direction are formed at intervals on a straight line parallel to the long side in the perpendicular cross section. In the hollow portions 3, 4, 5, there are inner protrusions 31, 41, 51 and inner concave lines 32, 4, which have the same shape as the outer protrusion 11 and the outer concave line 21 and face in the same direction.
2 and 52 are formed on a straight line parallel to the long side in the perpendicular cross section. Note that one or more hollow portions may be provided.

The base surface 33 of each of the inner protrusions 31, 41, 51,
43, 53 and the long side surfaces of the base surfaces 34, 44, 54 of the inner grooves 32, 42, 52, which have the rectangular cross-sectional shape, are cut grooves 35, 36, 45 along the extrusion direction. 46, 55, and 56 are provided.

As described above, the manner in which the hollow extruded material is used will be explained.

When this hollow extruded material is used, for example, as a wall material, the outer convex strip 11 and the outer concave strip 21 are usually fitted and joined in a tongue-and-groove state in the vertical direction. Therefore, hereinafter, one short side direction will be described as an upper part, and the other short side direction will be described as a lower part.

During construction, if narrow objects (short objects in the vertical direction) are required due to layout etc., as shown in the second diagram,
For example, if the cut is made at the second stage hollow part 4,
This cut includes a surface 43' connecting the convex base surface 43 of the hollow portion 4 and the cutting groove 45, and a surface 43' connecting the concave base surface 43 of the hollow portion 4.
4 and the cutting groove 46. Then, the inner convex line 41 and the inner concave line 42 are fitted together,
If both the upper and lower cut surfaces 43' and 44' are connected facing each other,
This extruded material main body A is shortened by the height _h1 of the hollow portion 4. The above-mentioned joint is firmly connected by using an adhesive, similar to an integrally molded product. Also, depending on the required dimensions, if the extruded material A is cut horizontally to match the inner convex base surface 33 of the first stage hollow part 3, the extruded material A can be reduced in size by the height _h2 , and the upper part The protruding strip 31 having the same shape as the original one side short surface (upper surface) 1 remains. Furthermore,
The extruded material body A can be shortened by h ₃ by cutting along the inner concave base surface 34 of the first stage hollow part 3 and the inner convex base face 43 of the second stage hollow part 4 (the first
figure). By selecting other cutting locations, hollow extruded materials of various heights can be obtained.

When cutting, since the cutting groove is included, just by hitting this part, it will break and the desired cut surface will be obtained.In addition, the joint part will have the same shape as the other cutting grooves, so the joint part will not look good. Inconspicuous.

Furthermore, as mentioned above, not only when the height is shortened, but also when a small-width object (shortened in the height direction) occurs during construction, the convex line and the concave line should remain so that they can fit together according to the above. It can be used for cutting and joining.
Furthermore, even if the upper and lower ends are chipped during transportation, the remaining parts after the defective parts are removed can be used by joining as described above. These greatly reduce the material loss rate.

In addition, novel joint patterns can be formed by manufacturing and combining hollow parts and cutting grooves provided at equal distances or unequal distances.

These cutting grooves are useful for increasing adhesive strength when finishing mortar or painting on the surface of the extruded material.

As described above, the present invention has an outer convex line and an outer concave groove that can be fitted vertically, and an inner convex line and an inner groove that have the same shape as the above-mentioned convex groove and are oriented in the same direction in the hollow part. Ta,
Since it is a hollow extruded material that can be cut in the middle in the vertical direction, connection is extremely easy and reliable, and construction is also simple. In addition, since even narrow items can be easily connected and used, it has become possible to significantly reduce the rate of material loss. Furthermore, by combining and joining pieces cut at different heights, joints with unequal distances in the vertical direction are formed, resulting in an innovative wall surface design. In addition, cutting is extremely easy, especially since cutting grooves are provided on the sides.
Moreover, the joints of extruded materials do not look unsightly and stand out.
Useful for increasing adhesive strength when mortar coating is applied to the surface of extruded materials.
