DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal-made square pillar with an anti-fogging device used as a metal base material in an interior construction work of a building.

[0002]

2. Description of the Related Art A metal base material widely used as an interior construction work for a building is generally specified in Japanese Industrial Standard JISA6517 steel base material for building (wall, ceiling). As a stud defined as a wall material, a stud having a U-shaped cross section is known. This wall stud is surrounded by metal on three sides, but the remaining one is open, so one or more anti-deflation holes are provided on the surface facing the open part, There was a problem in that it could not be used unless the base material was reinforced through this channel.

The open portion is formed in an overbend shape so that its U-shaped ends are directed inward to each other so as not to be displaced by fitting a spacer which is another member.

[0004] Since both surfaces of the overbend shape are naturally board-attached surfaces, a spacer for correcting the overbend is fitted into the open portion, and the portion where the spacer is fitted is a dot. Other parts remain overbend.
In this case, if a seam between the boards comes to a portion where the overbend state is maintained, there is also a problem that a stagger occurs at the seam.

Therefore, in recent years, as shown in FIG. 14, a square cylindrical steel prism 1 'is formed of a metal plate, and the end of the metal plate is formed on one of the four surfaces of the steel prism 1'. Are connected to each other substantially at the center to form a planar connection portion 2 '.

When this conventional steel square pillar 1 'is used, runners 18' and 19 'are provided on the ceiling slab and the floor surface as shown in FIG.
8 ', 19' and a plurality of steel square pillars 1 ', 1',.
The construction speed is high because the work is completed by fitting the squares, and as described above, since the rectangular tube shape is formed, there is no misalignment at the seam between the boards.

[0007]

However, FIG.
, The steel square pillars 1 ', 1',... Are merely fitted into the upper and lower runners 18 ', 19', and the steel square pillars are inserted into the intermediate portions in the height direction of the wall surface. Since there is no member for connection, the lateral wrenches are particularly weak, and the lack of anti-fretting leads to the following problems.

[0008] That is, since there is no countermeasure against horizontal weep, the height of the wall is limited (for example, the upper limit is 2.7 m), so the range of use is limited, and the current diversified architecture There is a problem that it cannot respond to things.

[0009] Further, since there is no connectivity in the middle portion in the height direction of the wall, there is a problem that the wall lacks robustness and tends to be unstable, and is particularly required in the present age where high-rise buildings are increasing more and more. The robustness of the wall cannot be sufficiently satisfied.

[0010] Further, when performing the work of sticking the wall to the board, the work is performed with a dry wall screw (that is, a small screw). There is also a disadvantage that it greatly affects the quality of the finish.

[0011] The present invention has been made in view of the above points, and an object of the present invention is to use a very simple means so that a metal square prism can be easily and reliably fixed. Is what you do.

[0012]

The basic structure of the present invention is as follows.
On opposing two surfaces 1a and 1c of the hollow metal square pillar 1,
A front notch opening 7 having a channel fitting groove 9 at the lower end for fitting the anti-deflection channel 6 is opposed to the front notch opening 7 and is equal to or larger than the lateral width of the channel fitting groove 9. The locking rim 10, which faces at intervals,
A notch opening 8 having a lower surface 10 on both sides thereof is formed, and a pressing force is applied to the locking edges 10, 10 against the upper surface of the channel 6 fitted in the channel fitting groove 9. The restricting metal fitting 13 which acts to restrict the upward movement of the channel 6 is locked, and the restricting metal fitting 13 is
An abutting surface 14a at the lower end abutting on the upper surface of the channel 6
And a flat plate-shaped restricting member main body 14 having an opening and being engaged with the outer surface of the locking rim 10, 10;
4 is formed by cutting and raising inward at a position above the contact surface 14a, and the locking lip 1
Inward convex pieces 15, 1 engaged with inner surfaces 0, 10
5 is provided.

In the present invention, there are the following preferred embodiments in the above basic configuration.

That is, the upper side of the locking rims 10, 10 in the rear side cutout opening 8 is fitted to the wide opening 12 for inserting the inwardly projecting pieces 15, 15 in the restricting bracket 13.
Is preferable in that the inwardly projecting pieces 15, 15 can be easily inserted into the inside of the locking lip 10, 10 side. In this case, the locking lip 10, 10 is removed from above. The taper shape in which the relative width becomes narrower as it goes downward is that the force for clamping the locking rims 10, 10 by the restricting metal main body 14 and the inward convex pieces 15, 15 in the restricting metal fitting 13 is strengthened. More preferred.

Further, at the upper end side of the rear side cutout opening 8,
It is preferable that a stopper 17 for restricting the upward movement of the control fitting 13 by applying a pressing force to the upper surface of the control fitting 13 is integrally formed with the stopper 17 in that the loosening of the control fitting 13 can be prevented.

Further, the stopper 17 is kept flush with the back surface 1c of the metal square pillar 1 before the mounting of the control fitting 13, and is outwardly directed from an appropriate position after the mounting of the control fitting 13. It is preferable to bend at a right angle from the viewpoint of facilitating the mounting of the restricting bracket 13 and the provision of the restricting force by the stopper 17. In this case, the lower end surface of the stopper 17 is fixed from its free end to the fixed end. Tapered surface 17a inclined downward toward the side
The reason is that the position where the stopper 17 and the upper surface of the restricting member 13 are in contact can be determined as the bending position (that is, even if there is a manufacturing error in the channel 6 and the restricting member 13, the bending position is determined correspondingly. ) Is more preferable.

Further, a pair of positioning projections 20, 20 which are engaged with both sides of the channel 6 when the control fitting 13 is mounted are integrally formed on the contact surface 14a of the control fitting 13 at the lower end of the control fitting main body 14. It is preferable to project from the point that the movement in the width direction of the channel 6 can be firmly restricted. In this case, the lower end portions of the positioning projections 20 and 20 facilitate the engagement with the both side surfaces of the channel 6. It is more preferable to form the tapered guide surfaces 20a, 20a in order to facilitate the engagement between the positioning projections 20, 20 and the channel 6.

The metal square pillar 1 is formed by bending a metal plate P cut to a predetermined width into a square tube shape so that both ends thereof are in contact at one point of a corner. At one end of the metal plate P, an inverted J-shaped bent portion 3 formed by bending the inside of the metal square pillar 1 and further bending the tip thereof outward is provided. At the other end, an inverted U-shaped bent portion 4 which is bent in an inverted U-shape is provided inside, and both are continuously fitted and crimped to form a corner-type connecting portion 2 which is vertically continuous. Is preferable in that the degree of freedom of use can be increased. In this case,
The formation of a rib 5 protruding in a U-shape inward from the base end of the inverted U-shaped bent portion 4 in the corner-type connecting portion 2 in the vertical direction is the disengagement of the corner-type connecting portion 2. It is more preferable in order to prevent this and to enhance the rigidity of the rectangular column 1.

[0019]

According to the present invention, the following effects can be obtained by the above means.

More specifically, the channel 6 for preventing deflection is fitted and positioned in the channel fitting groove 9 at the lower end of the front cutout opening 7 formed on one of the two opposing surfaces of the hollow metal square pillar 1. The locking edge 1 of the rear side cutout opening 8
The locking member 13 for restricting the upward movement of the channel 6 with respect to 0, 10 is locked. This is performed by the clamping force between the fitting main body 14 and the inwardly protruding pieces 15, 15 engaged with the inner surfaces of the locking rims 10, 10. Therefore, the movement of the channel 6 in the left-right direction (that is, the lateral direction) is restricted by the channel fitting groove 9, and the upward movement is restricted by the restricting bracket 13. Anti-fretting will be ensured.

According to the preferred embodiment of the present invention, the following effects can be obtained.

That is, the upper side of the locking lips 10, 10 in the rear side cutout opening 8 is fitted to the wide opening 12 for inserting the inwardly projecting pieces 15, 15 in the regulating fitting 13.
In this case, the operation of inserting the inwardly projecting pieces 15, 15 of the regulating fitting 13 into the inner surfaces of the locking lips 10, 10 becomes extremely easy. In that case, the locking edge 10,
10 is formed in a tapered shape in which the relative width becomes narrower from the upper side to the lower side, the wedge effect due to the tapered shape acts strongly when the regulating fitting 13 is pressed down, and the regulating fitting main body 14 and the inward convex piece 15 are formed. Locking edge 1
The pinching of 0 and 10 is further strengthened, and the upward movement of the channel by the restricting bracket 13 is reliably obtained (that is, the channel 6 is securely fixed).

Also, at the upper end side of the back side cutout opening 8,
When a stopper 17 for controlling the upward movement of the control fitting 13 by applying a pressing force to the upper surface of the control fitting 13 is integrally provided, the upward movement of the control fitting 13 is reliably performed by the restricting force of the stopper 17. It is regulated (that is, the regulation fitting 13
Of the channel 6 is surely prevented).
More securely.

The stopper 17 is kept flush with the rear surface 1c of the metal square pillar 1 before the mounting of the control fitting 13, and is directed outward from an appropriate position after the mounting of the control fitting 13. In the case of bending in the right angle direction, the restricting force can be provided by the stopper 17 only by bending after attaching the restricting bracket 13, and it does not become an obstacle when the restricting bracket 13 is attached. In this case, when the lower end surface of the stopper 17 is a tapered surface 17a inclined downward from the free end side toward the fixed end side, the position where the stopper 17 and the upper surface of the regulating fitting 13 are in contact is defined as the bending position. The channel 6 and the regulating fitting 13
Therefore, even if there is a manufacturing error, the bending position is determined correspondingly, so that the stopper 17 can more reliably apply the regulating force.

Further, a pair of positioning projections 20, 20 which are engaged with both sides of the channel 6 when the control fitting 13 is mounted are integrally formed on the contact surface 14a of the control fitting 13 at the lower end of the control fitting main body 14. If protruding from
The movement in the width direction of the channel 6 is firmly regulated by the positioning projections 20, 20, and the fixing of the channel 6 becomes more reliable. In this case, tapered guide surfaces 20a, 20a for facilitating engagement with both side surfaces of the channel 6 are provided at lower end portions of the positioning projections 20, 20, respectively.
Is formed, the engagement of the positioning projections 20, 20 with the channel 6 can be achieved very easily by the guiding action of the tapered guide surfaces 20a, 20a.

The metal square pillar 1 is formed by bending a metal plate P cut to a predetermined width into a square tube shape so that both ends thereof are in contact at one point of a corner. At one end of the metal plate P, an inverted J-shaped bent portion 3 formed by bending the inside of the metal square pillar 1 and further bending the tip thereof outward is provided. At the other end, an inverted U-shaped bent portion 4 which is bent in an inverted U-shape is provided inside, and both are continuously fitted and crimped to form a corner-type connecting portion 2 which is vertically continuous. In this case, any opposing surface of the metal quadrangular prism 1 may be used as a surface for forming the notch opening or a surface for attaching the board, and the degree of freedom of use is increased. In this case, when the ribs 5 protruding in a U-shape from the base end of the inverted U-shaped bent portion 4 in the corner-type connecting portion 2 are formed continuously in the vertical direction, the corner-type connecting portion 2 can be prevented from being dislodged by the ribs 5, and the rigidity of the metal square pillar 1 can be enhanced.

[0027]

According to the present invention, the hollow metal quadrangular prism 1 has a flexible shape with respect to the channel fitting groove 9 at the lower end of the front side cutout opening 7 formed on one side of the opposed two surfaces 1a and 1c. In the state where the stopping channel 6 is fitted and positioned, when the regulating metal 13 for regulating the upward movement of the channel 6 is engaged with the engaging rims 10, 10 of the rear side cutout opening 8, the regulating metal 13 is engaged. The locking of the locking edges 10, 10
And the locking rim 1 engaged with the outer surface of the
Since the channel 6 is obtained by the pinching force between the inward convex pieces 15 and 15 engaged with the inner surfaces of the channels 0 and 10, the lateral movement of the channel 6 is restricted by the channel fitting groove 9.
The upward movement of the channel 6 is regulated by the pressing force of the regulating fitting 13, and is extremely simple means (that is, the channel 6 is inserted into the channel fitting groove 9 of the front cutout 8).
And mounting of the control fitting 13 to the locking rims 10 and 10)
Thereby, there is an excellent effect that the metal square pillar 1 is reliably prevented from being deflected.

When the metal square pillar 1 having such a structure is used as a wall base material, the channel 6 securely fixed is used.
As a result, the rigidity of the wall structure can be improved, and the height limitation of the conventional type can be eliminated. Moreover, a plurality of front-side cutout openings 7 and rear-side cutout openings 8 are formed as a pair at appropriate intervals in the vertical direction of the metal square pillar 1, and each of the front-side cutout openings 7 has a channel fitting groove 9. If the channel 6 is fitted and positioned in such a way that the restricting metal fittings 13 are attached to the locking rims 10 and 10 of the rear side cutout opening 8, it is possible to cope with a case where a wall surface having a considerable height is formed.

Further, since the robustness of the wall surface is improved by the enhancement of the connectivity of the wall surface (in other words, the reinforcement of the anti-fretting), the effect that the workability at the time of attaching the board is remarkably improved is also obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1 FIGS. 1 to 7 show a structure and an assembled state of a metal square pillar with an anti-fretting device according to Embodiment 1 of the present invention.

As shown in FIGS. 1 and 2, the metal square pillar with the anti-fretting device of this embodiment is formed by cutting a metal plate P cut to a predetermined width so that both ends thereof are in contact at one corner. It is constituted by a hollow metal square pillar 1 which is formed by bending into a cylindrical shape.

At one end of the metal plate P,
An inverted-J-shaped bent portion 3 is provided, which is bent inside the metal square pillar 1 and further bent at the front end thereof toward the outside. The other end of the metal plate P is provided at the other end. , Inside U
An inverted U-shaped bent portion 4 that is bent in a letter shape is provided, and the two are continuously fitted and crimped to form a corner-type connecting portion 2 that is vertically continuous. With such a configuration, the flat connection portion 2 'is not located at the center of one surface of the steel square pillar 1' as in the case of the conventional steel square pillar 1 '(see FIG. 14). Any of the four surfaces 1a to 1d of the metal quadrangular prism 1 can be selected as a notch opening forming portion and a board attaching surface described later.

Further, in this embodiment, the ribs 5 protruding inwardly from the base end of the inverted U-shaped bent portion 4 of the corner-shaped connecting portion 2 in the metal square pillar 1. Are formed continuously in the vertical direction. The ribs 5 serve to prevent the corner-type connecting portion 2 from coming off and to enhance the rigidity of the metal square pillar 1.

Of the four surfaces 1a to 1d of the metal square pillar 1, one of the two opposing surfaces 1a and 1c is a front surface and a back surface, and approximately the center in the horizontal direction between the front surface 1a and the back surface 1b,
A front notch opening 7 having a channel fitting groove 9 at the bottom for fitting a channel 6 having a U-shaped cross section for preventing deflation with an open side facing downward, and a back surface facing the front notch opening 7 Side notch openings 8 are formed respectively.
The other two opposing surfaces 1b and 1d of the four surfaces 1a to 1d of the metal quadrangular prism 1 are used as boards.

The front side notch opening 7 is formed at the bottom thereof and has a channel fitting groove 9 having substantially the same width as the width of the channel 6 (ie, the width in which the lateral movement of the fitted channel 6 is not allowed). And a rectangular opening 11 continuous above the channel fitting groove 9 and having an opening area larger than the width of the channel fitting groove 9 and capable of changing the attitude of the channel 6 from the vertical direction to the horizontal direction. (See FIG. 3). The depth of the channel fitting groove 9 is set to be slightly higher than the height of the channel 6.
It is desirable to cope with manufacturing errors.

On the other hand, the rear side cutout opening 8 is formed with locking edges 10, 10 rising from both side ends of the bottom surface 8 a located on the same horizontal line as the bottom surface 9 a of the channel fitting groove 9 in the front side cutout opening 7. The locking lip 10,
Reference numeral 10 denotes a tapered shape which faces at an interval larger than the lateral width of the channel fitting groove 9 and whose relative width decreases from the upper side to the lower side. In addition, this locking edge 1
The upper side of 0 and 10 is a wide opening 12 for inserting the inwardly protruding pieces 15 and 15 of the regulating fitting 13 to be described later (see FIG. 4). The width of the wide opening 12 is larger than that of the rectangular opening 11 of the front side cutout opening 7.

The restricting fitting 13 is a member for restricting upward movement of the channel 6 by applying a pressing force to the upper surface of the channel 6 in a state of being fitted and positioned in the channel fitting groove 9. As shown in FIG. 5, it is made of a metal plate material having a thickness equal to or greater than the thickness of the metal plate P constituting the metal square pillar 1. And this regulation fitting 1
As shown in FIG. 6, reference numeral 3 denotes a rectangular restricting fitting main body 14 having a contact surface 14a at the lower end for contacting the channel 6.
And a part of both sides of the regulating metal body 14 with the contact surface 14.
Inward convex pieces 15, 15 cut and raised inward at a position above a, and an operating portion 16 bent at a right angle from the upper end of the main body 14 of the regulating fitting in a direction opposite to the inward convex pieces 15, 15. And The inward convex piece 15,
Reference numeral 15 denotes an engagement portion which is engaged with the inner surface of the locking lip 10.
10 and the engagement edge 10 of the restricting fitting main body 14
10 The locking rim 10, 1 is formed by the pinching force with the engagement with the outer surface.
The locking of the regulating fitting 13 to zero is obtained (see FIG. 4).

The operating portion 16 facilitates the operator to press down with his / her finger when locking the regulating fitting 13 to the locking rims 10. The position where the inward convex piece 15 is formed and the height of the locking lip 10 are determined by the lower end surface of the regulating fitting 13 (that is, the contact surface 14a).
It is needless to say that they are set so that they can maintain the engaged state in a state where they are in contact with the upper surface of the channel 6.

As shown in FIG. 5, the regulating bracket 13 is
At the wide opening 12 in the rear side cutout opening 8, the inward convex pieces 15, 15 are placed on the inner surfaces of the locking lips 10, 10 from the state where the inward convex pieces 15, 15 face the inner surface of the rear side cutout opening 8. It is attached by being pushed down while being engaged. At this time, due to the wedge effect of the locking rims 10, 10 having a tapered shape in which the relative width becomes narrower downward, the locking rims 10, 10 formed by the restricting metal main body 14 and the inwardly projecting pieces 15, 15. The pinching force of 10 is further strengthened, and the upward movement of the channel by the restricting bracket 13 is reliably obtained (that is, the channel 6 is securely fixed).

Incidentally, as described above, the regulating fitting 13 is attached by the clamping force between the regulating fitting main body 14 and the inwardly projecting pieces 15, 15 with respect to the locking rims 10, 10.
The upward movement of the channel 6 is supposed to be restricted, and such a means is sufficient in most cases. However, the building is subject to vibration, and the regulation fitting 13 is influenced by the vibration.
It cannot be said that there is no danger of loosening of the mounting state.

Therefore, in the present embodiment, the rear side cutout opening 8 is formed.
Is pressed against the upper surface (specifically, the operation unit 16) of the control fitting 13 on the upper end of the
The stopper 17 for restricting the upward movement is provided integrally.

The stopper 17 is a tongue-shaped piece extending from the upper end corner to the center of the back side cutout opening 8.
4 is kept flush with the outer surface (ie, the back surface 1c) of FIG.
After the mounting of the restricting bracket 13, the restricting bracket 13 is bent outward at right angles from an appropriate position.
(I.e., a solid line shown in FIG. 4). The lower end surface of the stopper 17 is a tapered surface 17a inclined downward from the free end side to the fixed end side. Note that the lower end of the stopper 17 on the fixed end side and the locking lip 1
It is a matter of course that a gap is formed between the upper end of the bracket and the upper end of the bracket so as to allow the inwardly projecting piece 15 of the regulating bracket 13 to be inserted.

In this way, the restricting force can be provided by the stopper 17 only by bending the mounting bracket 13 after the mounting of the mounting bracket 13, and does not hinder the mounting of the mounting bracket 13. In addition, the position where the stopper 17 and the upper surface of the regulating metal 13 are in contact can be determined as the bending position. Even if there is a manufacturing error in the channel 6 and the regulating metal 13, the bending position can be determined correspondingly. Is more reliably obtained.

Next, a specific description will be given of a case where the metal square pillar having the above structure is used as a wall surface base material.

First, as shown in FIG. 7, for example, U-shaped runners 18 and 19 are arranged on the ceiling slab surface and the floor surface such that their open sides face each other.

Next, the plurality of metal square pillars 1
The upper and lower ends of 1... Are fitted into the upper and lower runners 18 and 19, and the metal square pillars 1, 1. At this time, the front surface 1a and the back surface 1c of each of the metal square pillars 1, 1,... Are oriented in the same direction. In this way, the board attaching surfaces 1b and 1d of the metal square pillars 1 are arranged in parallel with the span direction of the runners 18 and 19.

Thereafter, the channel 6 is oriented vertically (that is,
Each of the square pillars 1 is inserted into the front side cutout opening 7 and the rear side cutout opening 8 of the metal square pillar 1 as an opening side in a horizontal direction, and then the channel 6 is placed in a normal posture (that is, a posture in which the opening side is downward). The position is changed to (1), and is fitted and positioned in the channel fitting groove 9 of the front side cutout opening 7. In this state, the movement of the channel 6 in the lateral direction is restricted by fitting into the channel fitting groove 9.

Under this condition, the restricting bracket 13 is attached to the locking rims 10 and 10 in the notch opening 8 on the back side of each of the metal square pillars 1. At this time, first, as shown in FIG. Then, the restricting bracket 13 is connected to the inwardly projecting pieces 15 and 1.
5 is located at a position facing the wide opening 12 in the rear side cutout opening 8 and is alternately moved left and right at that position, thereby inserting the inward convex pieces 15 and 15 into the inner surface side of the rear surface 1c. At this time, since the stopper 17 is flush with the back surface 1c, the stopper 17 does not hinder the mounting of the regulating fitting 13. After that, when the operating part 16 of the regulating fitting 13 is pressed down by applying a finger force to the regulating fitting 13, the inwardly projecting pieces 15, 15 are engaged with the inner surfaces of the locking rims 10, 10. By continuing, the contact surface 14a at the lower end of the control fitting main body 14 contacts the upper surface of the channel 6 (see FIG. 4). At this time, since the relative widths of the locking rims 10 and 10 are narrowed downward, a wedge effect is exhibited,
The clamping body 10 and the inwardly protruding pieces 15, 15 firmly sandwich the retaining edges 10, 10.

Thereafter, when the stopper 17 is bent outwardly at right angles by a finger force, the stopper 17 is bent from a portion where the tapered surface 17a at the lower end of the stopper 17 and the upper surface of the operation portion 16 of the regulating bracket 13 are in contact. As a result, the restriction force can be imparted by the stopper 17.

When the channel 6 is assembled as described above, the movement of the channel 6 in the lateral direction is restricted by the channel fitting groove 9, and the upward movement is restricted by the restricting fitting 13 and the stopper 17. The metal square pillars 1, 1... Are firmly connected to each other by the channel 6. In this state, wetting of the metal square pillars 1, 1,... In the directions of arrows A, B is completely prevented, and a robust wall surface structure is completed.

Thereafter, a board 20 for upper application is stretched on either of the board application surfaces 1b and 1d using a dry wall screw (small screw). Since the robust wall base structure, which is prevented from wetting, is obtained by securing the connectivity by the channel 6, the board attaching operation can be performed very quickly and reliably.

Second Embodiment FIG. 8 shows a metal square pillar with an antiflation device according to a second embodiment of the present invention.

In this embodiment, only the corner-type connecting portions 2 are formed at both ends of the metal plate P in the metal square pillar 1, and the ribs 5 in the first embodiment are omitted. Even if it does in this way, there is no problem in using as a base material.
The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted to avoid duplication.

Third Embodiment FIGS. 9 to 13 show a metal square pillar with a deflector according to a third embodiment of the present invention.

In the case of the present embodiment, the abutment surface 14a of the lower end of the main body 14 of the restricting bracket 14 in the restricting bracket 13 in the first embodiment.
A pair of positioning projections 20 engaged with both sides of the channel 6 in a state in which the regulating fitting 13 is mounted;
20 are protruded integrally, and the positioning projections 20, 2
At the lower end of 0, tapered guide surfaces 20a, 20a for facilitating engagement with both side surfaces of the channel 6 are formed. In some cases, the ribs 5 in the metal square pillar 1 may be omitted.

With the above configuration, the movement of the channel 6 in the width direction is firmly restricted by the positioning projections 20 when the restricting bracket 13 is mounted, so that the fixing of the channel 6 becomes more reliable. At the same time, when the positioning projections 20, 20 are engaged with the channel 6, the engagement of the taper guide surfaces 20a, 20a can be obtained very easily by the guiding action of the tapered guide surfaces 20a, and the mounting workability of the regulating fitting 13 is also improved.

The other constructions and functions and effects are the same as those of the first embodiment, and the description is omitted to avoid duplication.

In each of the above embodiments, the case where one channel 6 is inserted through the metal square pillars 1, 1,... Has been described. When the height dimension of the metal plate becomes large, the front side cutout opening 7 and the rear side cutout opening 8 are formed as a pair at a plurality of positions in the vertical direction, and a plurality of channels 6, 6,. 1. The connectivity between them may be increased.

In the case of a double stud in which two metal square poles 1 are built in contact with each other, the cutout openings 7 on the front side of the metal square pillars 1 adjacent to each other are opposed to each other. Of course it will be built.

The present invention is not limited to the configuration of each of the above-described embodiments, and it is a matter of course that the design can be changed as appropriate without departing from the gist of the invention.
