Post structure assembled from wooden parts and method of its manufacture Stolpkonstruktion ihopsatt av trädelar 5 och förfarande för framställning av denna

The invention relates to a post structure assembled from wooden parts, in particular a vertical post for wall panels, which consists of board elements connected to each other by adhesive joints.

The invention further relates to a method of manufacturing a post structure, in which the post bar is assembled from the board elements by gluing into a continuous beam structure.

The emerging construction industry has now increasingly begun. . use a variety of sheet products such as hardboard, particle board, blockboard and gypsum board as partition materials because they are easy and 20 quick to build. Said board products replace the horizontal or oblique boards previously used as partitions. All of the above-mentioned back materials require a support frame with vertical posts to secure or nail it.

It is known from the prior art to use sawn or planed beams as vertical posts in various wall constructions, which have a cross-sectional area of about 5 x 10 cm or about 5 x 5 cm and are of the required length in each case. These known posts, which are one solid wood, twist and twist as they dry.

If boarding is used as the wall surface, there is no disadvantage of slight twisting of the posts, but said building boards require an absolutely flat and straight fixing and nailing base so that the boards do not twist or crack.

Since the previously known partition posts have proved unsuitable when used in conjunction with plates, efforts have been made to develop replacement products that do not twist and warp. Such 35 2 35404 are e.g. posts made of "finger-jointed" adhesive beams and so-called multi-ply poles. A product made of relatively thick cross-glued veneers must be compared to plywood. Profile posts made of steel or aluminum have also been used, especially in partition wall structures.

The aforementioned prior art posts are expensive. In addition, the metal lithium poles can only be attached with screws and the multi-ply poles are also a bad nailing base because it contains a lot of adhesive resins.

10

The general object of the invention is to provide a new post structure, in particular a partition post, and a method of manufacturing the same, which can eliminate the disadvantages discussed above and provide new, more advantageous solutions to the problems discussed above.

It is a particular object of the present invention to provide a new post structure, in particular a partition wall post serving as a base for fixing plates, which can be made of an even cheaper raw material.

It is a particular object of the invention to provide a post structure which does not warp or twist and which is thus a good nailing and fastening base for wall panels and the like.

In order to achieve the above and later objects, the post structure of the invention is mainly characterized in that the post bar is composed of surface board layers, the non-edged wide sides of which are glued to each other or to the intermediate board layer in the post bar. -30 in the longitudinal direction of the structure from different points with butt joints, preferably with glued joint joints.

The method of manufacturing a post structure according to the invention is mainly characterized in that in the method the lower board element of the post bar is placed the tongues or the like of the ends of the board elements are treated with glue and that the gluing of the beam is continued in the order 5 so that the bottom board element extends furthest, after which the post bar assembled as described above is subjected to pressing and drying steps.

The post product according to the invention is made of a cheap raw material and is easy to manufacture. The post according to the invention is a very good nailing and fastening base for boards, and it does not warp or twist. The post according to the invention uses as a raw material a surface board created in connection with sawing, the cross-sectional area of which is generally of the order of 2 x 10 cm. A surface board is cheap because it is less-edged. Its price 15 is only about 25% of the price of the glue bar. The surface board forms a good nailing pad because it has almost no dry hard branches.

The surface boards from which the post product is composed may be of different sizes. A tongue is machined at the ends of the surface boards to form a butt joint 20 between successive board parts.

The post according to the invention does not require an almost regular expensive finger joint in longitudinal joints, because the post product is used as a vertical support and its bending stress is low. The rigidity of the posts 25 is increased by the wall plates to be nailed to them. Because the surface boards are usually of different sizes, butt joints come at different points in the beam, which increases the rigidity of the post.

In the following, the invention will be described in detail with reference to some application examples of the invention shown in the figures of the accompanying drawing, to the details of which the invention is in no way limited.

Figure 1 shows a cross-section of a post blank according to the invention.

Figure 2 shows a post structure according to the invention seen from the side.

Figure 3 schematically shows the manufacture of a post structure according to the invention.

Fig. 4 shows the step of the method according to the invention, in which the post blank made according to Fig. 3 is split in half into two post structures.

Figures 1 and 2 show the composition of the post structure 10 according to the invention. The post structure consists of surface boards having a low edge 14, namely a lower board 11, an intermediate board 12 and an upper board 13. The surface boards 11, 12 and 13 are glued together with adhesive joints 19. The surface boards are placed in the post structure 10 so that 15 full-edged sides 17 and 18 outwards. According to Fig. 1, the surface board pieces 11,12,13 of the post structure are connected to the next surface board piece by butt joints 15 with matching male tongues 15K and female tongues 15N. The joint connection 15 is preferably glued.

Figures 3 and 4 show a preferred method of manufacturing a post structure according to the invention.

According to Fig. 3, the lower board 11 is placed on either a fixed or movable base such as rollers 20 with the underside 14 side up and glue strips 19a are drained on the upper surface 25 and the end tongue 15K is coated with glue. An equally long or preferably shorter spacer 12 is placed on the lower board 11, from which the upper surface and the tongue 15K are glued. The underside 14 is placed on top, preferably the upper board 13, which is preferably shorter than the intermediate board 12, in which only the tongue 15K is glued.

30

The gluing of the beam 10 is continued in the order that the lower board 11 is the longest, then the intermediate board 12 and lastly the upper board 13. As the manufacture of the beam 10 progresses, it is not necessary to select board lengths, because the order can be maintained by adding extensions. Of course, care must be taken to ensure that the male tongue 15K and the groove of the female tongue 15N come together at the butt joint 15.

5 85404

The beam 10 can be manufactured as a continuous rod, preferably so that it moves forward, e.g. on a roller base 20 for gluing, pressing and imaging devices (not shown).

5

After drying, the beam 10 is split by sawing along the plane S-S shown in Fig. 4. Thus, by splitting, two post bars 10A and 10B are obtained from one post bar 10, in which the full-edged sides 17 and 18 will preferably act as flat nailing bases for different wall plates 10 or the like. The post bars 10A and 10B are sawn into sections of suitable length according to the application.

The post bar 10 to be assembled from the three surface board layers 11,12,13 has been described above. Surface boards can, of course, vary in width and thickness. Thus, according to the invention, the beam rod 10 can be made of, for example, two or four layers of surface boards, and the posts can also be of different sizes, depending on the intended use. When making heavier posts, the splitting sawing step S-S is not required, but the post bar 10 is cut into posts of suitable length.

The following claims set forth within the scope of the inventive idea defined by the invention may vary and differ from those set forth above by way of example only.
