Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to structural members formed from sheet metal for use in building construction, and more particularly to metal studs for use in forming loaded and unloaded walls and partitions.

When constructing a building, wooden or metal implants are used. Metal studs are highly preferred in the construction of various buildings because they are termite resistant, rot resistant, and fire resistant. Metal studs are lighter than wooden studs for the same length, so
Suitable for use in walls and partitions that do not bear any load in general buildings. Metal studs are preferred in the construction of high-rise buildings and are particularly desired by architects and construction engineers to avoid adding excessive weight to the building.

Metal studs support wall cladding and are often used for panels made of Tex or plasterboard.

These walls also carry equipment, such as wiring elements and the like.

It is desirable that such a wall can be easily penetrated to the front or rear without interfering with the above-mentioned equipment.

It is desirable that all metal implants reduce the inherent effects of metal, such as heat conduction and sound propagation. On the outside walls, heat loss becomes an important issue. Various attempts have been made with external wall implants, in some cases reducing the path for heat transfer by providing openings in the implant.

In the inner walls, the implants should provide maximum sound transmission. Additionally, the implant must be as rigid as possible to hold the panel in place, yet at the same time as lightweight as possible.

In the past, typical metal studs for drywall (dry waltz or plasterboard walls) generally had three sides; the channel section had a central web and two side walls; is bent into another channel section whose cross section presents a channel. This further channel portion is continuous along the length of the implant.

Implants of this type have been used extensively in the past, often with satisfactory results. However, various drawbacks also arise from this configuration. First of all, this central web is a generally continuous barrier throughout the height of the wall. Therefore, openings must be provided in the web in order to pass the wiring through the web. This results in relatively sharp edges that can cause damage to the wiring elements. Moreover, these openings have weakened the implant and compromised its rigidity, and only very limited methods can be used to form such openings.

Another drawback is that unless such implants are formed from very thin metal, they tend to be unnecessarily heavy and therefore expensive to manufacture.

In addition, if possible, the overall dimensions of the implant should be
It is desirable to have the same dimensions as the X4 type. However, for economic and other reasons, the web width of metal studs has typically been reduced, allowing the use of slightly thinner walls than would be possible with wood studs.

This resulted in greater sound transmission through the walls.

In addition, the presence of a continuous web of metal from one side of the wall to the other facilitated sound transmission.

Even more serious drawbacks appear when installing drywall. When attaching drywall to such implants, workers use power screwdrivers and self-tapping screws, similar to power drills. These self-tapping screws have a specially configured self-drilling tapping point that can be applied directly to the metal sheet of the implant, allowing the opening of the self-tapping screw to pass through the implant and then tightening the screw to remove the drywall panel. It is adapted to be fixed to the implant. These screws were quite satisfactory. However, as economic reasons reduced the thickness of the metal sheet of the metal implant, the sidewalls of the implant became relatively flexible. Therefore, when a drywall worker inserts a screw by pressing the threaded portion against the side wall of the implant, the side wall of the implant tends to flex. This results in the screws slipping to one side, thereby damaging the drywall.
Work will be delayed. Therefore, thin implants for drywall of this type have caused various problems.

However, if the above-mentioned disadvantages can be avoided, it is clear that it is desirable to make the metal sheets used in implants of this type as thin as possible.

In order to overcome the above-mentioned disadvantages, the present invention provides a metal implant of lightweight construction. The implant is made of thin gauge sheet metal and has two generally L-shaped angle sections extending parallel to each other and a plurality of angle sections extending integrally from one angle section to the other. a strut member spaced apart from each other and forming an opening between these strut members; a flange formed on the strut member; an enlarged root formed at the end of the member and a plurality of concave lip portions formed laterally with respect to the L-shaped angled portion, each L-shaped angled portion spaced apart parallel to each other abutting the panel; a flange located in generally parallel spaced planes to which the wall covering is applied, the rib portion being formed within the flange adjacent the L-shaped angled portion; The portions are evenly spaced along the entire length of the L-angled portion to prevent deflection of the flange as the securing member is inserted through the flange.

It is also an object of the invention to provide a wall structure comprising such a structural member and a wall panel attached to the structural member.

Various novel features of the invention are particularly pointed out in the claims. BRIEF DESCRIPTION OF THE DRAWINGS For a better understanding of the operational advantages of the invention and its specific uses, reference is made to the following description and accompanying drawings in which preferred embodiments of the invention are described.

First, refer to FIG. A wall is shown comprising panels (lO), typically made of plasterboard or drywall material, supported by spaced vertical metal studs (12), indicated by reference numbers (12). There is. The implanted member (12) of this example is a panel (lO
) is the standard size 4X8ft (approx. 120x 240cm)
+++) typically 16 inches (approximately 40 cm)
placed at intervals. In other types of walls, the spacing between the implants may be wider or narrower, but this spacing is in any case known and does not form part of the invention.

Typical wall construction uses channel sections, typically formed of metal, to secure the top and bottom sections of each stud to the top and bottom sections, which are attached to the floor and ceiling covering fibers. (none shown).

An intermediate cross member (not shown) extending between adjacent implants intermediate the top and bottom members is also provided for supporting the implants in some types of walls.

In any case, all these structures are well known in the industry and do not constitute the present invention.

In Figure 1, wall panels are installed on both sides of the stud so that the inside wall is visible, but when used as an outside wall, panels are usually installed on only one side and are Of course, another panel material can be attached to the other side depending on the configuration.

It will be appreciated that the panel (10) is secured to the implant (12) by a securing device, typically referred to as a drywall screw, as indicated by reference number (14). Although such a screw (14) does not form part of the invention, it is significant in that it includes what is known as a self-drilling self-tapping tip.

In a typical drywall screw, such a tapping tip is cut away to provide a sharp cutting edge.

When such a tapping tip metal implant (12) is penetrated and a screw is turned with, for example, a powered screwdriver or similar device, the tapping tip will drill a hole in the implant by itself, thereby removing the panel. It is tightened to secure it to the implant.

Typically 30 to 50 screws are used per panel. It can be appreciated that if there were any difficulty in threading and tightening the screws through the implant, this would substantially slow down the drywall installation process and increase overall costs.

On the other hand, it is desirable to form the implant itself from a thinner gauge material to reduce weight and material costs.

As mentioned above, these two factors create a mutual contradiction in that the smaller the gauge (dimensions) in manufacturing the implant, the more difficult it is to screw in the screw. .

As clearly shown in FIGS. 2, 3, and 4, the drywall implant according to the present invention has a generally L-shaped inner angled portion (20) and an outer angled portion (22). have

The terms "inside" and "outside" are merely used for convenience in distinguishing and explaining such angle portions.

It will be understood that in the case of an indoor wall, of course, there is no equivalent to an internal or external surface.

In addition, since the implant can be used in either the front or back orientation, or the top or bottom orientation, one need only consider which is the inside and which is the outside at a given time.

The structure of both angle parts (20), (22) is the same.

The same part has surface flanges (24), (26) and side flanges (28), (30) extending at right angles to the flanges.
). The free edges of the surface flanges (24), (26) are bent as indicated by designations (32), (34). As is well known in the art, the outer surfaces of the surface flanges (24), (26) are provided with surface structures forming a plurality of closely spaced small recesses. These recesses are not shown, but in any case, these recesses hold the tip of the screw so that it does not slide laterally on the metal surface, making it easier to insert it into the metal plate. That is completely understandable.

A plurality of generally diagonal supports (36) extend between the two angled portions (20), (22). Each support (36) has a web portion (38) and a sidewall (40).
)including.

The inner free edges of the side flanges (28), (30) are bent inwardly as indicated by designations (42), (44). The inner folds (42), (44) are continuous extensions from the side wall (40) of the support (36).

The inner part surrounded by the support material (36) is a substantially trapezoidal opening (46).

The root or end of the support (36) is designated by the instruction number (48).
) and (50), the stress is smoothly transmitted from the angle portions (20) and (22) to the support member (36).

A plurality of laterally recessed lips (52), (54) are formed to increase the stiffness of the surface flanges (24), (26) and reduce the metal thickness. In a preferred embodiment, these lips (52), (54)
is the end of the support member (36), that is, the widened part (4) of the root.
8) and (50).

Such ribs also have angle parts (20), (22)
are formed at regular intervals along the length of the

Furthermore, ribs (56), (58) are formed extending to the root of the support, these ribs preferably extending from the ribs (52).
, (54).

Ribs (56), (58) are formed during one step in the process of manufacturing the implant. The ribs (52), (54) are formed after bending the angled portions (20), (22) in the longitudinal direction.

The method of use of the present invention is self-evident upon viewing FIG.

Once the implant members are stood upright adjacent to each other at a predetermined distance, panel members are applied and secured with screws.

the surface flange (24) by pushing the screw into the panel member;
When (26) is pressed, the tip of the screw pierces and penetrates the surface flange. In this case, the thread of the screw forms its own corresponding thread in the surface flange, so that the screw is tightened to the surface flange.

Surface flange (24) due to the pressure applied by the screw tip
, (26) tend to flex, but this tendency is due to the fact that the recessed lips (52), (54) have a surface flange (
24), (26) at right angles to the side flanges (28), (30). Therefore, the tendency of the screw tips to slide on the surface flanges (24), (26) can also be suppressed to a minimum.

It is of course possible to place any equipment, if necessary, through the opening (46) in the implant (12) before installing the panel material, such as electrical wires, water pipes, or similar items. .

The side flanges (28), (30) provide a convenient means for attaching the electrical wiring box using, for example, sheet metal screws or drywall screws.

Once the wall has been covered with paneling, the opening (46)
It can be seen that by virtue of the fact that the support material (36) has relatively few metal parts, the tendency of the wall to transmit vibrations and sound is substantially reduced. Good morning. Sound transmission can therefore be kept to a minimum.

At the same time, the angled portions (20), (30) are connected by a lateral support (36), further including a channel portion along its length and angled portions (20), (22). The inside bent part (42
), (44) side flanges (20), (30
), deflection of the implant (12) is substantially reduced.

The improved stiffness inherent in implants according to the present invention allows them to be formed from thinner metal sheets. This results in weight savings and material cost savings without unacceptable loss of stiffness.

Another embodiment of the present invention is shown in FIGS. 3 and 4. The implanted member according to this embodiment has an inner strut (60) and an outer strut (60).
62), each post comprising a surface flange (64) supporting the wall covering against the plane of the wall.
Side flange (66) at right angle from 4)! A is extending. Return flange (68) perpendicularly from side flange (66)
) extends. The free edge of the surface flange (64) is bent inward at right angles as indicated by the reference numeral (70).

The free edge of the return flange (68) has an instruction number (72)
It is bent inward at right angles as shown in , and its surface is located approximately midway between the surface of the side flange (66) and the surface of the inner bent portion (70).

The two columns (60), (62) are interconnected in this example by a diagonal support (74). The support (74) has a substantially channel-like configuration in cross-section with an enlarged root (76) from which side walls (78) are formed at right angles.

A substantially triangular opening is provided in the middle of the support (74).

Since the flange (77) extends completely around the aforementioned opening and along the free edge of the free edge (72), a continuous right-angled reinforcing lip providing additional strength is provided. can get.

Surface flanges (
Ribs (80) recessed at right angles are provided at predetermined intervals at the right angles where the surface flanges (64) and side flanges (66) intersect to resist deflection of the side flanges (64).

A rib (82) similar to rib (80) is attached to the side flange (6).
6) and the return flange (68) at a right angle, the angle can be increased by an additional degree.

If desired, adjacent ends of rib (80) and rib (82) may be arranged to coincide to provide a continuous rib through side flange (66).

However, in many cases these ribs (80), (82) are formed at separate steps during the manufacture of the implant, so it may not always be practical to have continuous ribs as described above. do not have.

However, in reality, even if the two lips are made to overlap or not to overlap, there is not much difference in the overall strength.

The enlarged root (76) may further include reinforcing ribs (86) extending from the free edge (72) to the return flange (68).

Still another embodiment (third embodiment) of the present invention is shown in FIG.

In this embodiment, right-angled L-shaped angle portions (90), (9
2) is formed, the L-shaped angled portion having a surface flange (94) supporting the panel material and side flanges (96) extending at right angles from the same flange.

An edge flange (98) is formed by folding over the free edge of the surface flange (94).

The L-shaped angled portions (90), (92) are integrally formed from a single sheet of metal and are connected together by interconnecting supports (100).

The supports (100) are separated from each other by openings (102), which in this case are circular.

The edge flange (104) has an opening (1
02) is formed by bending the entire periphery inward.

To provide layer strength to the support material (100), the support material (100)
Lateral reinforcing ribs (106) are formed extending preferably straight from 100) towards the surface flange (94).

To provide layer strength to the L-shaped angled portions (90), (92), laterally recessed ribs (10) are spaced laterally on the implant similar to the embodiment of FIG.
8) is provided, which prevents the surface flange (94) from deflecting.

The foregoing has been a description of preferred embodiments of the invention and is merely illustrative of the invention. Therefore, the present invention is not limited to the above-described embodiments, and various modifications may be made within the spirit of the claims.
