Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a thermally efficient steel stand button with an edge flange having an opening for embedding in concrete, and a joint or precast panel common to the stud. It is related to.

(b) Prior Art Precast panels, typically finished on one side, offer a number of structural advantages. In many cases where precast panels are used, the cost of the building is reduced. Additionally, panels with an attractive appearance can be used for the exterior. In many cases the panel material is concrete in combination with reinforcement. Typically, concrete panels are between about 1 inch and 2 inches thick. Panels of this thickness require some form of structural reinforcement to provide stiffness. Furthermore, if the panel is used as an exterior support wall, the panel Fi must cooperate with some form of structural member.

Typically, this type of panel is erected in place to create a finished exterior surface, and the interior surface of the panel must be coated and finished in a subsequent step.

For other applications, the inner surfaces of the panels may be prefabricated at the factory and provided with insulation so that a complete wall system can be achieved prior to installation.

Applications of this precast panel include providing exterior wall systems for commercial and industrial buildings, high-rise office buildings, apartment buildings, etc., as well as interior wall systems with various finishes as required.

Such panel systems are often supported on building structures and typically provide no load bearing capacity other than wind resistance.

In these cases, the panels must be fixed to the building structure.

However, a precast panel of this type must meet all the above-mentioned requirements in a satisfactory and efficient manner and at a reasonable cost. For most construction projects, the actual weight of the materials used in the construction is very important. The weight of the material affects the cost and transportation costs of the material and also limits the way the material can be handled at the construction site.

However, in addition to all these constraints, especially when it comes to high-rise building construction, the weight of the structural materials weighs heavily on the overall building design! ! It is the European factor.

If a significant reduction in material weight is achieved, it becomes possible to optimize the overall building design and save construction costs. Therefore, for this reason, it is desirable that the thickness of the precast panel be reduced to a minimum compatible with meeting these requirements.

Accordingly, design developments in such precast panels have been made along the lines of decreasing panel thickness and cooperating with metal structure studs or channels on one side of the panel.

In this way, the exterior surface of the panel exhibits a finished appearance and the interior surface of the panel has a plurality of metal stud housings or channels partially embedded in its surface.

Using these techniques, it is possible to create a
It has been found that precast panels can be made between 1 and 2 inches thick.

The reinforcing steel is associated with the panels, and the structural steel studs have a portion embedded in the concrete on one side of the reinforcing steel web.

Traditionally, steel studs used for this purpose have been simple C-channels. One edge of the channel simply rests on a reinforced steel mesh.

However, this is not necessarily a satisfactory method of installation. The edges of the channels create weak lines within the panel.

Additionally, simply using a C-shaped channel creates obstructions within the wall. If electrical work has to be done through the wall, an opening must be made through the channel.

Another important issue is heat transfer through the channels when the panels are used for building exteriors. The metal creates cold spots on the interior walls of the building, resulting in
This results in condensation inside and outside the walls, known as 'ghosting'.Thermal loads within the building are also increased.

The weight of the metal stanod itself is also an important factor in the overall weight of the panel. The weight reduction that can be achieved without loss of stiffness yields significant benefits.

In some cases it may be desirable to use such panels as floors or ceilings, but heretofore studs have been insufficient to support the load.

Therefore, for all these reasons, it is desirable to have a thermally efficient steel stud with an edge flange with an aperture embedded in the concrete and designed so that the weight of the steel stud is reduced to a minimum. It is recommended that precast panels be provided with steel studs. The steel stud has integral fixing means for fixing it to the precast slab and cooperates with apertures along its length that effectively reduce heat transfer through the stud and eliminates the need for weak straight sections of the slab. I'm avoiding life. (c) Problems to be Solved by the Invention and Means for Solving the Problems In order to solve the various problems mentioned above, the present invention consists of a stud member with good thermal efficiency, and the member has two parallel and spaced apart structures extending parallel to each other. a plurality of spaced apart strut members extending integrally between the structural members and having openings therebetween; and a plurality of spaced apart strut members integrally molded into one of the structural members and extending angularly therefrom into the slab. It consists of an intermediate flange having an embedded and penetrating opening, and a hook l-IJ snap formed integrally with the intermediate flange and arranged at an angle thereto.

More specifically, the problem of the present invention is to
The object of the present invention is to provide a precast panel having a slab and a plurality of studs having intermediate flange buttons and hooking studs embedded in the slab. The hooking strip is arranged at an acute angle within the slab and extends only on one side of the intermediate flange, with the poured concrete material extending through an opening in the intermediate flange.

More particularly, it is an object of the invention to provide a precast panel with a stud element as described above, which has additional reinforcement means on the angle element remote from the relay strip.

A further object of the present invention is to provide for driving the housing of the hooked strinop to include upper and lower frame members arranged in a predetermined parallel spaced relationship and extending from one edge to the other and extending between the upper and lower ends. It is an object of the present invention to provide a precast panel that cooperates with a plurality of stud members having a panel material that can be used.

(d) Embodiment As shown in FIG. 1, the precast panel 10 has a first surface 12) and a nub 12 typically made of concrete.

A steel reinforcing net R (FIG. 3) is embedded within the slab 12. A plurality of steel stud members 14 are attached to one stroke of sp2 12 in a manner described below.

As best shown in FIGS. 2 and 3, the stud member 14 is comprised of an inner and outer L-shaped angled portion 20 and 22. Each angle part 20.

9, 2 are each flange 24. 9, 6k and strut 7 Tsunge 2
It is made up of 8,30. The flange 24 has a reinforced edge.
It is effectively molded integrally with the flange 25.

Each one of the flanges 24 and 26 and the strut flange za,
30 forms a right angle, so the two flanges 24.9,
6 are arranged in parallel and spaced apart planes.

In order to connect the two angled sections 20.9,2 together, the angled strut 32 extends integrally between them. The struts 32 are effectively formed into a generally three-sided channel shape by bending down the edge flange portions 34 on one or both sides.

Angle part 20, 22j? and the support column 52 are all 1
Molded in one piece from sheets of sheet metal. Typically, they are formed by rolling molding techniques. Openings are drilled between the posts 52.

This type of stud (D opening is shown at 36) is considerably lighter than an equivalent stud with a conventional C-section.Furthermore, imposing a cutout on the stud between the edges Reduce heat transfer through the stud and at the same time provide sufficient opening for construction through the stud.If necessary, the edge of the strut flange 212), sa may be bent downwards to form a flange with an integrally molded opening 36. may be entirely circumferentially defined by.

To secure the studs to the precast panel, a relay flange 40 extends perpendicularly from the flange 26 and is grooved.
A hook strip 42 extends from the flange 40 to secure the flange 40 into the Conch1 notebook panel. M
As can be seen in Figure 3, the hooking strip 42 is arranged at an acute angle on the first side of the slab 12, in accordance with an important feature of the invention.

The opening 44 is. As shown in FIG. 2, blanks are punched out from the intermediate flanges 40 at intervals to allow concrete to be poured during the manufacture of panel 1 (12). The aperture 44 may be shaped to extend into the hook strip 42, as will be seen in further implementations of such studs below.

In the manufacture of the precast panel 1 (12), the stud members 14 are assembled together and fastened to the framework, similar to the framework used in the erection and installation of walls. That is, if multiple stands have one center to the other, for example
Arranged parallel to each other and spaced 6 or 24 inches apart, the housing may have upper and lower struts attached to either end, if desired.

The manufacture of the gathering panel 1 (12) is carried out by pouring precast material (typically concrete) to a sufficient depth into a horizontal mold. Typically, it is poured to a depth of about an inch and a half. The actual thickness will be determined based on various factors and design specifications.

The reinforcement net R is placed on the concrete surface.

The entire rectangular framework of studs is lowered in the mold housing onto the reinforcing mesh and then pressed down into the concrete.

When the desired depth is reached, the hook strips 42 and relay flanges 4 are placed into the concrete and the flanges 26 rest on the first side 12) of the concrete.

The rectangular framework of studs may be fixed as required so that the framework is not further submerged in the enclosure in which the panels are installed and cured.

Once cured, the entire panel is freed from the mold.

It has been found necessary to provide an optional attachment between the stanod member and the reinforcing steel mesh in the concrete. However, for convenience, if some type of installation is required, e.g. to assist during the actual assembly and casting of the panel, the reinforcing netting may simply loop a wire (not shown) through the netting and through the opening. They are attached by tying them together at various intervals.

However, in some cases, it is necessary to first place a reinforcing net on top of the concrete poured into the mold, then lower a framework of studs onto the reinforcing net, which then pours the concrete to the desired depth. Continue lowering the framework in the trench.

This has the effect of inserting the reinforcing net into the concrete to a prescribed depth. In fact, the reinforcing net does not sink any further, but remains in place in the concrete.

Panels made in this way were found to exhibit great strength and durability. The studs are then fixed to the slab and the panels are moved so that they are fixed in place.

The low heat transfer properties of the studs substantially eliminate cold spots and condensation on interior walls previously produced by conventional metal studs.

The discontinuous transition flange 40 is also very superior to the continuous non-interval flange.

Typically, for a 1.5 inch thick slab,
Continuous relay flanges are α5~Q. Form a continuous barrier or line of weakness within the slab to a depth of 75 inches. This does not look good and also makes the panel fragile.

The material of the slab flows around the hook strip 42 and through the opening 44 in the relay flange 4 (12).

The slab effectively maintains its integrity, at least in the area of the opening 44, and in this way it also becomes stronger and allows thinner slabs to be used.

In some cases it may be desirable to use panels according to the invention on the floor or ceiling.

Based on the load to be supported, it is preferable to increase the load carrying capacity of the stud.

According to another embodiment shown in FIG. 4, any or all of the stanods may be modified by providing triangular reinforcing tubes 50 outwardly from the first side 12) of the slab 12.

The tube 50 may be provided in place of the inner angled portion shown in FIG.

The tube 50 has a side wall 52 integrally formed with a triangular cross section.
．． 54 and a bottom wall 56.

If necessary, the reinforcing ribs are attached to the side wall 52.5 at intervals.
4.It is molded within 4 to give it great strength.

The side walls 52,54 are secured together by any suitable means 58, such as spot welds, rivets, forge welds, or the like.

The tubular structure of the reinforcing tube 5 (12) adds increased stress resistance to the strut. By placing it in a plane away from the slab, it is placed in tension, reducing the deflection of the slab.

The triangular shape of the reinforcement may be replaced by a generally closed T-shaped guard feature (not shown) if desired.

Its structure is self-explanatory and requires no further explanation.

Since the material of the slab flows freely through the opening 44 of the relay flange 4 (12), the slab resulting from the use of this construction will be considerably stronger, and the possibility of using a continuous relay flange will also carry considerably heavier loads. can be supported.

However, in addition to these advantages, providing an opening in the intermediate flange 40 helps reduce problems caused by differences in thermal expansion coefficients between the material of the stud itself and the slab.

If the openings 44 are formed only in the relay flange 4 (12), the hook strips 42 may be made somewhat narrower than if these openings 44 extend in the hook strinop 42 housing.

In use, panel 10 is typically attached to form the exterior wall of a building, although panel 10 may be used as an interior wall if desired. Insulation is placed between the studs and an interior wall panel, such as gypsum wallboard, is attached to the inner surface of the studs with mounting flanges.

Referring to FIG. 5, another embodiment of a steel stud member 6 (12) for use in a precast panel according to the present invention is shown. The stud member 60 is comprised of an inner angled portion 62 and an outer angled portion 64, with the portion 6
2 is similar to the previously described stud member 14 in that it is provided with a reinforcing edge flange 65. Post 66 extends between post flanges 67 and 68 and defines an opening 69 therebetween.

The outer angled portion 62 is made up of a mounting flange 70 that is integrally molded with a relay flange 72 . A relay flange 72 extends therefrom at an acute angle and hooks the hook strip 7.
4 are integrally molded. An aperture 76 is formed in the intermediate flange 72 and such aperture 76 operatively extends partially into the hook strip 74 as shown.

Referring to FIG. 6, a stud member 80 is shown using a panel according to the present invention. Stud member 60.8 (
12) are represented by the same numbers to avoid duplication of explanation.

The stud member 80 is not provided with a mounting flange 70 but instead has a relay flange 8 integrally molded with the strut flange 68 and extending angularly therefrom.
This differs from the stud member 8.0 in that the stud member 8. A hook strip 84 is integrally molded into the intermediate flange 82 and extends at an angle therefrom to be disposed at an acute angle in the face of the slab (not shown).
