Description
Technical field
The present invention relates to be used to support the Steel Joist (steel stud) of dry wall plate (drywall panel); And be specifically related to have lower thermal conductivity and form reeded empty stomach keel (open web stud) by predetermined interval, groove has the given shape that is used for ccontaining dry wall screw.
Background technique
For building, in particular for setting up the Steel Joist of dry wall, replacing rough ground for many reasons.It is rare that wood is becoming.Wood perhaps can rot warpage, is perhaps encroached on.
Wooden inflammable.And in many cases, for no other reason than that it is heavy and huge and become no longer suitable for transportation.Yet, wooden compared two major advantages with Steel Joist, promptly wood has lower thermal conductivity, and wooden with ccontaining and keep the for example such dry wall fastening piece of screw.
Obviously, if can solve these two subject matters of comparing with wood with Steel Joist, then expectation uses Steel Joist to overcome wooden various shortcomings.In addition, because when mounted, Steel Joist does not receive the influence of outdoor environmental conditions, and they can process and can not lose performance by reclaiming steel, therefore for the steel from other goods recovery good outlet are provided.In the past, many proposals have been proposed for the various designs of Steel Joist.In many cases, Steel Joist is rolled into simple C type cross section.The simple cross section of this type has web and two " leg " sidewall in other words, thereby on the cross section, forms simple rectangular channel.The dry wall plate arrives these two legs with the dry wall screw.
These simple C type cross section keel are widely used in the commercial tall building.But they are also unsatisfactory for various reasons, and most of reason is known.
Simple C type cross section keel or process by heavy steel, and this type steel is heavier than desired or economically feasible; Perhaps process, and this makes them too soft by the steel of light-type.Under the too thin and soft situation of this type keel, just becoming is difficult to mounting screw and comes mounting plate.
Heavy steel will allow mounting screw easily, but this steel can transmit noise and thermal conductivity is high.And use more steel than expectation.This possibly cause in the multi-story structure floor load excessive.Model is heavy more, and raw-material cost is high more.
Can think that light-dutyer steel more meets expectation, but this steel possibly be difficult to install.The vertical member and the plane member that with this light-type C type cross section steel are the wall of framework maybe be too weak and soft, and wall possibly vibrate.Vertical keel piece is fastened to the horizontal channel to process the framework difficulty that also becomes, because fastening piece (the special tapping screw that normally uses in the sheet metal) is difficult to be fixed on securely in the steel as thin as a wafer of member.Generally speaking, employed typical dry wall screw is not suitable for the sheet metal keel in the process that dry wall is fastened to rough ground, especially than the sheet metal keel of Light Gauge Steel.
The tapping screw of sheet metal is designed with cutter apex point (chisel drill point) and threaded stem.These screws will remain in the sheet metal more firmly.Yet when the steel that uses than light-type, steel possibly be thinned to only has one or two screw thread to catch metal on the screw rod.Another factor is, the Light Weight Steel Shape in this simple C type cross section is usually too soft and can not let screw insert fast.The speed that the workman installs the dry wall plate that so just slowed down, and finally increase the whole cost of work.
Flat (plain) C type cross section keel be not suitable for set up exterior wall or set up heat gradient in the wall maybe significant wall or transmission sound become the wall of problem.The keel in this simple cross section have high thermal conductivity, and abut at the dry wall plate under the situation of side of C type cross section keel and can produce the condensation that be called as " diplopia (ghosting) " along the line on the inwall.
Keel can be formed with separated opening, so that reduce thermal conductivity.This keel can be classified as " on an empty stomach " muscle.Keel also can be formed with various flanges and ridge, so that keel are firmer.Yet in the past, this keel are more expensive than flat C type cross section keel, and do not find as yet to be widely accepted.Obviously, being formed with the keel of complicated opening, rib and ridge will be more expensive than the keel that roll into simple C type cross section.Therefore; If make complicated empty stomach keel than the more competitive words of simple C type cross section keel; Its basis must be that although keel possibility manufacture cost is high slightly on an empty stomach, it is installed more easily and be rapider; And can process by obvious light-dutyer steel, therefore use material still less than simple C type cross section keel.On an empty stomach keel are also useful to reducing the sound through the wall transmission and alleviating on the ground weight of building.For exterior wall, keel will be than the keel more attractive in simple C type cross section on an empty stomach, and this is because the thermal conductivity of exterior wall is a problem.To relax along the problem of inner wall surface formation " diplopia " condensate line of empty stomach keel than lower thermal conductivity, and this problem perplexs the problem of flat C type cross section keel just.From this reason, must exhaust all effort thermal conductivity is decreased to bare minimum, keep other advantages simultaneously with respect to C type cross section keel.
Equally very expectation is, uses the low empty stomach keel of thermal conductivity to make exterior wall, and wherein exterior wall uses thin shell concrete (thin shell concrete) and steel to reinforce the combined type external wall slab that keel (stud, pillar) constitute.This combined type external wall slab has numerous advantages with respect to the solid concrete outside plate.One of remarkable advantage is that this composite sheet combines outside concrete surface with the concrete flat slab of relative thin, and the Steel Joist that is mixed for reinforcing in the inboard of this flat board in addition.Thin concrete flat slab has been practiced thrift concrete cost, but also has alleviated the weight on the ground of building.Steel is reinforced keel and is extended from the internal surface of thin concrete flat slab, and be made in the building can be by the attached keelson of dry wall.
In addition, make this light section reinforcing keel and have some advantages: reduce the cost of material, alleviate the weight of composite sheet, and reduce the thermal conductivity of each keel.Last advantage is derived from the following fact: compare with heavy keel, light-dutyer steel will only transmit the less heat of thermal unit number because of quality reduces.
Another factor comes from and in the empty stomach keel, has used light-dutyer steel.This keel are widely used in and support the dry wall plate.Wallboard is attached on the leg of keel with screw usually.Under the situation of the edge of two wallboards to edge butt joint, the edge of these two wallboards must and be emitted on the leg of single keel.The width of leg maybe be less than 5cm.Stay next narrow relatively support zone so just only for the edge of each wallboard.Screw must pass through each panel edges and be fixed in the identical keel leg, remains on the identical leg with the edge with two butt joint wallboards.
Utilizing light section to make under the situation of keel, when inserting screw, the trend that leg just has bending or reverses.This trend is more remarkable under the situation of empty stomach keel because this moment model even maybe be littler than the model of traditional C type cross section keel.This trend can alleviate through in keel, mixing various ribs, web and flange, although this moment, the keel model alleviated, rigidity increases.
To above situation, the present invention has further utilized two wide screw containing grooves of the leg that is arranged in each keel.These grooves form by predetermined interval abreast, are beneficial to insert screw fastener.The width of groove is greater than the width of screw tip, so that help screw to penetrate, and even produces because of the pressure of screw tip at the steel on the sheet metal under the situation of certain distortion and also allows screw to pierce sheet metal.
Between two grooves or the keel leg on next door not only flat but also straight so that support plate edge securely.These grooves also help when inserting screw, in leg, form the recess (recess) of tubulose.The recess of these tubuloses is that screw thread provides safer engagement.

Embodiment
As stated, with form in light weight and that have a Steel Joist of lower thermal conductivity the present invention is described.These keel have a plurality of special characteristics, and these special characteristics are fit to be convenient to by the attached dry wall plate of the mode of following explanation, and be its characteristic with lower thermal conductivity and low sound transmission, will describe as following.
Fig. 1 and Fig. 2 illustrate keel 10, are explanation the present invention, can these keel be summed up as substantially " keel on an empty stomach ".
Keel 10 have web 12.Web 12 limits outer attachment face 14 and inner face 16.Web 12 is formed with two parallel grooves of web longitudinally 18.
Be the main web opening 20 that is trapezoidal substantially between two grooves 18.Opening 20 limits long limit and minor face parallel to each other longitudinally, and the hypotenuse (diagonal side) that connects the end of long limit and minor face.
Between main web opening 20, rib 22 oblique extending on the keel.Vertically flange extension 24 extends along the parallel edges of each opening 20.Tiltedly flange 26 extends along each limit of each rib 22. Flange 24,26 plane bendings with respect to web 12 meet at right angles, to reinforce keel.In flange, vertical flange extension 24 is extended through staying more metals from web simply.
These vertical flange extensions 24 are with another right angle 28 bendings, so the L-shaped cross section of their edge part, and these edges are in parallel with web but in the plane that separates.
In this way, these flanges 24 form the rectangle reinforcing passage 30 on three limits together with the adjacent portion of web 12; This passage has central part and two relative walls, extends along the parallel longer sides of each main web opening 20 with than minor face, to obtain bigger intensity.
Along each limit of each rib 22, flange 26 constitutes substantially leg-of-mutton peak point 32, to gain in strength.The width of rib 22 varies along its length, and the some place is the narrowest approximately therein.
At every end of each rib 22, has the circular rib opening 34 that centers on by annular flange flange 36.Circular rib opening 34 limits two narrow throats that separate 38,40, and a narrow throat is arranged on every side of each circular rib opening.
The narrow central region of throat 38,40 and each rib that is positioned at every end of each rib all constitute the heat transfer limitations district in other words heat transmit barrier.Therefore, any heat that passes the keel transmission only can transmit through these thermodynamic barriers.
With reference to Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, will see the cross section of these throats (identifying and illustrate the front view of throat among Fig. 4).To have to through these throats through any heat of keel transmission.
This keel that are designed with opening, rib, flange and passage can be by light-duty steel plate manufacturing.In fact above-mentioned steel can be the lighter model of model than traditional simple C type cross section metal keel; This is because various flanges, edge, passage and opening all help to make said keel more more strong than traditional simple C type cross section keel, and has better load-bearing characteristic.
Therefore will understand, throat becomes as the function of heat transfer barrier even is more effective.
In preset time length, heat transfer must depend on the temperature gradient and the volume that the steel of heat-transfer path is provided in the keel.
Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9 illustrate the cross section of various throats.These thermodynamic barriers are included in the steel that given position is used to pass the minimum volume that keel conduct heat.Therefore, no matter have what kind of temperature gradient in the keel, all must be constrained to the heat transmission that another side carries out from one side of keel, the heat of any value all can only be transmitted in these (given) constrained position.
On the numeral of following steel corresponding to various models, can find out that said keel compare with flat keel, from one side of keel to the minimizing of another side heat transfer number.
| The model of steel | 20(0.88mm) | 18(1.15mm) |
| |
100％ | 100％ |
| The empty stomach keel | 4% to 8% | 20% to 25% |
These numerical value that more than illustrate are theoretical value.
In fact more possible is, these numerical value in one way or another kind of mode for example depend on that outside heat loss condition outside wall or the building (these conditions maybe be not only relevant with temperature, but also relevant with wind chill index etc.) will receive certain restriction.Because the volume of the composition of steel and (possibly) place wall between keel thermoinsulation material and the difference of type have some slight changes.
Obviously, suppose that the model of steel is lighter than the model of conventional flat keel, then the actual volume of the metal of each throat or limitation part promptly significantly reduces.
Because the design of keel makes it firmer than conventional flat C type cross section keel on an empty stomach, and because the design of keel only limits to throat conducts heat, so keel of the present invention significantly are superior to traditional C type cross section keel.
In the present embodiment, along each edge of web 12,, web generates web leg 42 thereby curving the right angle.In the case, each web leg is formed with limit lip 44, and limit lip 44 inwardly changes 90 ° of angles.In some bigger keel, limit lip 44 can as shown in Figure 2ly prolong, and is formed with another groove.
In the present embodiment, each web leg 42 is made up of plane steel plate, is formed with two parallel sawtooth grooves 46 in each web leg.The outer surface of each web leg limits plane area or zone 48.This allows the dry wall plate to lie on the plane domain 48 of web leg outer surface.The material of two dry wall plates converge and the situation of docking under, the edge of each plate will be placed on the halfwidth of web leg 42.The dry wall screw will pass the material of the dry wall plate of these two butt joints, get into their grooves 46 separately.Under the situation in the middle of the dry wall plate is placed on the leg 42 of keel 10, they will be fastening through the dry wall screw of single file.These screws will be contained in one of two grooves 46.
In order to help dry wall plate location, be formed with center score line (central scribe line) 50 along each web leg 42.Score line 50 is along mid point (line) location of web leg, equidistance between two grooves 46.This makes accurately arrangement board of dry wall setter, make any two adjacent plates all with the overlapping identical distance of the web leg of keel.Guarantee that thus screw inserts in the groove of web leg exactly.
The possessive construction of web 12 and recess (indentation) are formed by web outer surface 14 and extend internally.This puts down not only but also straight the surface of the directed outwards of web outer surface and web leg 42, so that other materials ccontaining and that put.Be (Fig. 3) under the situation of web leg 42 of dry wall plate at said material, can therefore the recline flat outer surface 48 of web leg 42 of dry wall plate keeps flat.
Each groove 46 is formed with linear type horn shape limit 52 (Figure 10).These horn shape limits form by the mode that helps to insert self threading pin 54.Self threading pin 54 is designed for especially dry wall plate 56 (Fig. 3) is fastened to Steel Joist 10.For this reason, screw 54 has from Drilling point (self drilling chisel point) 58.These chisel edges have the tip, and the tip forms the circular cone around cone angle.The angle of epiconus is greatly in approaching 40 ° to 50 ° scope.
The angle on the horn shape limit of groove 46 is between about 75 ° and 90 °.Groove is therefore wideer, and chisel edge is narrower.In this way, the chisel edge of each screw can arrive in the degree of depth of groove downwards fully.Guarantee thus to make screw begin immediately to pierce in the steel through inserting the rotation of instrument, the insertion instrument is generally electric screw driver.
Cause web leg deflection and bending if the screw pressurized is excessive, chisel edge is trapped in maintenance in the groove.Prevent the screw lateral twisting like this and skid off the web leg.The left side of Figure 10 illustrates and is about to the screw that begins to pierce, and the right side illustrates the screw that inserts fully.
In case insert fully, will see that screw will make the sheet metal in the groove of web leg form funnel shaped metal tube 60 substantially.Can see that by figure the metal tube that forms 60 like this can mesh several screw threads of screw, and therefore fixedly confining force is provided.
Various wall system will need the keel of different size and size.
It is the web leg of 92mm to 102mm that the keel of not load-bearing will have width usually.
Load-bearing and can to have width than the keel of heavy load be the web leg more than the 152mm.
Connect at two plates under the situation of web leg of keel, the web leg plays the effect at edge of the dry wall plate of ccontaining two edge butt joints.
Therefore, groove 46 should equidistantly separate in the relative both sides of intermediate score line 50 each other.These grooves also should equidistantly separate with web 12 and limit lip 14.
At interval the width A of parameter and the web leg of B is as follows to be used for the groove of various keel of different in width.
| The keel size | Leg wide (A) | Groove is (B) at interval |
| 92mm is to 102mm | 41mm is to 51mm | 17mm is to 26mm |
| 152mm | 41mm is to 64mm | 17mm is to 39mm |
Change by some, can keel of the present invention be used to make the shell composite concrete plate of reinforcing through Steel Joist.
The reinforcing keel 70 (Figure 11, Figure 12 and Figure 13) that are used for above-mentioned purpose will be formed as described above in fact, and part identical among the figure uses identical reference character, except only one web leg 42 exceptions that curve the right angle.
What replace another web leg is built-in edge 72; Built-in edge 72 forms and embeds thin shell concrete plate (not shown), and is thick thick to about 4.5cm from about 3.25cm usually, is not used in qualification but these accompanying drawings only are used for explaining.Edge 72 comprises the right-angle type root 74 that extends from web 12.In the present embodiment, be extended with middle part 76 from root 74 with meeting at right angles.Pass middle part 76 with separation spacing and be formed with opening 78, flow through through these openings to allow concrete.The metal part 80 of coming out from opening 70 punching presses is along still keeping coupled condition on one side and by deflection, thereby extends to a side at middle part 76 with meeting at right angles.
76 edge is formed with continuous limit lip 82 along the middle part, and continuous limit lip 82 curves the right angle and extend with metal part 80 relative directions on the edge.
Can increase additional strength to the embodiment of Fig. 1 and Figure 11 like Figure 14 and (embodiment) shown in Figure 15.
In the case, keel 90 have the characteristic identical with above-mentioned characteristic and have identical reference character.Being substantially leg-of-mutton additional recess 92 (Figure 14) or being the linear recess 94 (Figure 15) of cardinal principle with nose circle through formation provides additional strength.
(Figure 16, Figure 17 and Figure 18) is formed with recess 102 in the end of each rib 22 in another embodiment's keel 100, and recess 102 is irregular triangle substantially.In recess 102, be formed with circular rib opening 104, acting as with the mode identical with Fig. 1 and Figure 10 of these circular rib openings limits throat to reduce heat transmission.
Compare with flat keel, the general effects of empty stomach keel of the present invention aspect heat transfer illustrates at Figure 19 and Figure 20.
Figure 19 illustrates the length of flat keel P.The heat transmission that keel are passed in a series of arrow A 1 representative.Heat is straight simply to pass the keel transmission, has no restriction.The model of steel is big more, and the heat that transmits is many more.
Figure 20 illustrates the length according to empty stomach keel 10 of the present invention.The heat transmission that empty stomach keel for example of the present invention are passed in a series of arrow A 2 representatives.
Obviously, in the keel 10 of Figure 20, heat is limited to narrow path, so the heat of actual transfer will be much smaller than the heat that flat keel transmitted of Figure 19.
Be the description of the preferred embodiments of the present invention more than, preferred embodiment only provides as an example.The invention is not restricted to described any concrete characteristic, but should understand all such modification all in the scope of claim of enclosing.
