Description

DETAILED DESCRIPTION OF THE INVENTION The present invention covers the front surface of a steel column in a prefabricated building, for example, and is attached to wall panels arranged on both sides of the steel column, and To provide a pillar cover that can be easily and neatly installed even when the distance is uneven or fluctuates.

For example, in a prefabricated building, the first
As illustrated in the figure, steel columns b made of square steel pipes are erected on foundation a, and wall panels P are placed between the steel columns (b).
The wall body is formed by arranging them in parallel and providing an outer surface layer c using so-called wall paint such as tile/crater paint or stucco paint on the outer surface. wall panel P,
A pillar cover d, which is fixed to P and covers the front surface thereof, is installed over the pillar and also serves as a base material. However, the conventional pillar cover d consists of a single plate-shaped body, and its both ends are directly fixed to the wall panels P, P by nailing, etc., so its width cannot be adjusted. Therefore, if the distance between the wall panels P and P varies due to manufacturing and installation errors of the steel column b and the wall panel P, installation becomes difficult. Furthermore, if the joint e between the steel column b and the wall panel P expands or contracts due to wind pressure, earthquakes, etc., the deformation force immediately acts on the column cover d, and the column cover d
There is also the problem of the outer layer c falling off, and the expansion, contraction and deformation at the joint e also causes cracks in the outer surface layer c.

The present invention is based on the fact that the installation length can be freely adjusted, so that it can be easily installed even when the distance between wall panels varies, and it also prevents cracks in the outer layer. For the purpose of providing a column cover, one embodiment will be described below, taking as an example the case where it is installed between wall panels P, P arranged on both sides of a steel column b made of a square steel pipe illustrated in FIG.
This will be explained based on the drawings.

In FIGS. 2 to 4, the pillar cover 1 of the present invention is
It consists of a pair of column cover pieces 2 and 3, and one end of the column cover pieces 2 and 3 is fixed to wall panels P and P arranged on both sides of the steel column b. Steel column b is foundation a
The beam f is erected at the top end and supports a beam f at its upper end, and the beam f has, for example, a lower flange of an I-shaped steel with lips i, i between which the upper end of the wall panel P can be inserted. is hanging down. The wall panel P has, for example, a wooden frame material 7 disposed in a rectangular shape, and an exterior material 9 and an interior material 10 are attached to the inner and outer surfaces of the frame material 7, and the frame materials 7, 7 located on both sides are shown in FIG. As shown on the right side of FIG. 1 , joint portions 12 and 13 are formed at different positions at both ends so that they can be juxtaposed with a stepped portion 11 . In addition, the joint part 1 facing the indoor side
The exterior material 9 is attached to the frame material 7 having a retaining portion 14 from its protruding end 7a. The lower end of the wall panel P is attached to the base metal k that is attached to the foundation a.
In this embodiment, as illustrated in FIGS. 3 and 4, the outer surface 7b of the side frame material 7 is fitted into and attached to the upright piece of the steel column b. It is attached so that it protrudes outward by a length of n. The joint joint portion 12, 1 facing the steel column b
3 includes a wedge piece 15 whose side surface is in contact with the steel column b;
Enter 16. In addition, the joint joint part 12 on the outdoor side
The length of the wedge piece 15 that is driven into the frame member 7 is the same as the length of the dowel part 12, so that the outer surface 15a of the wedge piece 15 is aligned with the outer surface 7 of the frame member 7.
B.

The pillar cover pieces 2 and 3 are bent bodies, such as colored steel plates, which have been subjected to anti-corrosion treatment, and their lengths are set approximately equal to the height of the wall panel P, and one of the pillar cover pieces 2 is , for example, the retaining portion 14 of the frame material 7
A stepped portion 22 having a mounting portion 21 at one end that abuts on the mounting portion 21 and bending inward by the thickness of the mounting portion 21.
the base plate part 23 inwardly and the mounting part 21 through the
A groove 25 is formed therebetween by providing a folded part 24 whose outer end is bent outward on the substrate part 23. The end of the folded portion 24 is curved outward to form a guide portion, and the mounting portion 21 is provided with a small hole 26 through which a screw, nail, or the like is inserted. The column cover piece 2 is fixed by nailing the mounting portion 21 to the retaining portion 14, and the groove 25 is attached to the steel column b.
parallel to the front surface of

The other pillar cover 3 has a mounting portion 31 having approximately the same width as the outer surface 15a of the wedge piece 16, and extends in a direction facing the pillar cover piece 2 via a stepped portion 32 having the same height as the exterior plate 9. Substrate part 3 having approximately the same width as steel column b
3, and a stepped portion 3 is formed at the outer end.
An insertion portion 35 is formed parallel to the base plate portion 33 and directed toward the attachment portion 31 via a side plate portion 34 having the same height as the base plate portion 2 and facing inward. The insertion portion 35 can be inserted into the groove 25 while pushing out the folded portion 24, and is attached to the mounting portions 21, 31 on the wall panels P, P arranged with the protruding end 7a in contact with the steel column b. When attached to the tip of the insertion portion 35 and the groove 25
The width is set so as to form a predetermined gap 〓g between it and the rear end of the front end.

However, in the pillar cover 1 of the present invention, the mounting parts 21 and 31 of the pillar cover pieces 2 and 3 are fixed to the retaining part 14 and the wedge piece 15 using the small holes 26 and 36, for example, so that the other ends can be fixed. Groove 25 formed
By inserting the insertion part 35 into the column and making the depth of the groove 25 relatively large, the installation length between the one ends of the column covers 2 and 3 can be freely adjusted, and as a result, As illustrated in FIG. 4, even when there is a gap l, l between the protruding end 7a and the steel column b, the insertion part 35 can be easily installed by moving the position inside the groove 25. It can be delivered easily and its installation is easy. Further, an elastic sealant made of, for example, urethane resin, silicone resin, etc. is applied to the joint _e1 between the side plate portion 34 and the facing exterior plate 9 of the side plate portion 34.
Or elastic sealing material S such as oil-based caulking material
At the same time, an outer surface layer c made of wall paint or the like is sprayed and formed except for the joint e ₁ to complete the wall. As a result, even when the wall panel P is displaced due to external force etc. and the distance l changes, the column cover pieces 2 and 3
can freely slide to prevent the column cover 1 from falling off, and the sealing material S absorbs the expansion and contraction of the joint _e1 , thereby preventing the occurrence of cracks in the outer surface layer c. Note that the joint _e2 on the step portion 32 side can be filled with an appropriate sealing material such as a non-expandable sealing material. Further, in this embodiment, since the outer surface 7b of the frame member 7 protrudes from the outer surface m of the steel column b, the outer surface m of the column cover 1 and the steel column b
A gap of length n can be formed between the pillar cover 1 and the steel pipe column b, thereby preventing thermal bridging between the column cover 1 and the steel pipe column b, and suppressing dew condensation on the indoor side of the steel column b.

As described above, the column cover of the present invention consists of a column cover that is fixed at one end to the wall panels arranged on both sides of a steel column, and has a groove at the other end and is inserted into the groove. Because it has an insertion part, its width can be adjusted freely, making it easy to install even when the lengths of the wall panels are different, and the length between the wall panels can change due to external force, etc. Even in such cases, the change can be absorbed and accidents such as falling off can be prevented.

Furthermore, by filling the joint between the column cover and the wall panel with an elastic sealant,
It can provide excellent effects such as preventing cracks in the outer layer.
