The specific embodiment
As already described, the invention provides a kind of floor system or Roof system that adopts the metal sheet joist, it has improved sound absorption characteristics to reduce the sound transmission from a floor to next floor.The present invention also provides and is applicable to the metal sheet joist of strengthening tabular floor of concrete slab or roofing.
The present invention also provides a kind of combination H type that forms by two joists are linked together back-to-back or I type haunched member, has made the method for this haunched member and the method that forms floor on length.
For illustrative purposes, " floor " speech is used for illustrating the layer structure of using at building (levelstructure), itself or play in building the effect of the floor that supports people or object, perhaps come containment building as roofing.As roofing the time, this structure has the gradient usually; Yet as floor the time, it is a level.The present invention can be equally applicable to arbitrary function.
With reference to figure 1 as seen, exemplify the present invention in this form with floor 10.Typically, floor 10 is made of combination metal sheet haunched member 12 and edge member 14.Typically, edge member 14 is supported on top edge (not shown), foundation structure or other structure of wall.Haunched member 12 is across the space that is surrounded by edge member 14, and the end portion supports of haunched member 12 is on edge member 14.
As shown in Figure 1, the combination haunched member 12 in the present embodiment is the composite membeies that are made of the 20 back-to-back placements of two identical joists.Like this, this combination haunched member has just formed H type or I type member.Each joist 20 is made by metal (being steel in this case) plate.Each joist 20 has basic for the web 22 on plane with along the edge of a wing, edge 24 of the lower side formation of web 22.The edge of a wing, edge 24 is by forming with this web of right-angle bending.Antelabium 26 is formed on the edge of a wing, edge 24 with the right angle again.To become clearer in the following description is, in web 22, by the part of metal sheet being carried out punching and dislocation but the other parts of not removing metal sheet form opening 28.
In this embodiment, opening 28 forms along the cardinal principle oval in shape of the elongated lengthwise of joist 20.Based on the reason that will illustrate, these openings are identical and symmetrical.Each opening 28 has along the opposed end that has semicircle or curved profile 30 of the central axis setting of web 22.
Along between the end 30 of opposite side, opening 28 is formed with the linear parallel side of the elongation of representing with Reference numeral 32.
Based on the reason that the following describes, if desired, can form the cross rib 34 (Fig. 2 and Fig. 3) of elongation in the end of joist, to provide higher rigidity in the joist end.
Be extended with and form and the edge of a wing, web 22 rectangular edge 36 around opening 28.Two linear side 32 along this opening have the support antelabium 38 that extends to form from the edge of a wing, edge 36 integral body.Support antelabium 38 and is formed by part web 22, part web 22 is partly gone out and dislocation along these linear side of opening 28, but it keeps connection as the part on the edge of a wing, edge 36.Support antelabium 38 with the plane parallel of web 22 but right angle bends 40 places with interval form.Like this, two reinforcing ribs that support antelabium 38 formation along two linear side 32,36 short groove shapes of extending of opening 28 from the edge of a wing, edge.Like this, support antelabium 38 and greatly strengthened joist 20 along the length direction of two linear side 32 of opening 28.
This feature allows opening 28 to be formed with big relatively size, thereby the pipeline (not shown) can pass the lateral dimension that opening 28 extends and only be subject to the opening that vertically passes web 22.Compared with the joist with triangle open mouth, this is great improvement.Based on the reason that the following describes, along the upside formation connection edge of a wing 42 of web 22.
It should be noted that the shape of opening 28 and position define extends the strut 44 that crosses web 22.This strut can reduce the sound transmission that passes this joist.Joist 20 also is formed with recess 46 in the opposite end of each strut 44, and strut 44 outwards opens up in the web 22 there.Center position at these recesses 46 is provided with the opening of going out 48, although opening 48 can be other shape, is circular this its.Opening 48 has been removed metal, and this provides better obstruction and improved its sound absorption characteristics the sound transmission that passes this joist.Joist among this embodiment is useful especially.Owing to kept the metal of the quite big quantity of dislocation, so it has high strength by die-cut openings 28.The major part of these metals is not removed but is retained, and folded-out to form the support antelabium 38 of groove shape, and it has formed the both sides of opening 28.
Fig. 1 to Fig. 6 shows the additional features of the joist 20 that is used to embed concrete slab.
Connecting the edge of a wing 42 is formed with about 45 degree from the bandy built-in edge of the web plane edge of a wing 50.This angle can change a little at various application.
The built-in edge edge of a wing 50 is outwardly-bent, and is formed with a series of opening or holes 52 that concrete flows that are used for.
The antelabium 54 that turns back 50 forms along the built-in edge edge of a wing, to embed in the concrete.
Thus, this embodiment provide be provided with the reinforcing rib that is used for concrete floor or coagulation scholar plate, have a high-intensity joist.The built-in edge edge of a wing 50 that is partially embedded in the concrete will provide adhesion the safest between joist and the concrete.
The metal sheet that this joist can adopt thickness to reduce.What can expect is to realize being reduced by at least a standard size or two standard sizes of possibility when enough supports being provided still for concrete floor or concrete slab.
This will reduce the cost of this concrete floor or concrete slab.
Fig. 9 shows the joist 100 of another form, and it has the feature that is suitable for supporting by the made floor of other sheet material such as veneer.
Joist 100 has web 102 and the identical side wing edge 104 and 106 that forms along this web either side.The lower limb edge of a wing 104 and the top edge edge of a wing 106 are identical and crooked with this web plane ground that meets at right angles.Whole edge antelabium 108 extends from the lower limb edge of a wing 104 and the top edge edge of a wing 106 abreast with this web plane.Rib 110 forms across joist 100 with preceding and the same.
Opening 112 penetrates web 102 as before and forms, and it has in the embodiment in figure 1 the elliptical shape of elongation substantially.
The edge or the edge of a wing 114 as before nearby (therearound) form.The linear side 116 of opening 112 and 118 is strengthened by the support antelabium 120 from the web 102 whole metal sheets that extend, and keeps the more metal of dislocation by forming opening 112 thus, and is applied to improve joist, rather than it is abandoned as waste material.
Antelabium 120 is folded into the right angle groove that extends along each linear side of opening 112, so that higher intensity to be provided.More metal will be retained in this joist, and this both can increase its intensity, can allow to reduce standard size again in the member that substitutes.Form in this web that have can be for the recess 122 of circular or other shaped aperture 124, as mentioned above to be used to reduce heat waste.In use, two such joists 20 or 100 are as Fig. 1 and shown in Figure 9 with back-to-back relation and put.If desired, can they be fixed together to form the combination haunched member by (not shown) such as for example spot welding.
Making joist 20 or 100 can be by at first forming opening 112 and the edge of a wing, edge 114 is carried out in suitable forcing press.This forcing press can be spiral moulding press (flying die press), but useful is, employing has two rotating mould backing rolls and the rotational pressure machine of the mould that is provided with on backing roll, in such rotational pressure machine, along with metal sheet moves betwixt, two backing roll rotations are so that mould lumps together or separately.At die-cut formation opening, form the edge of a wing, edge in around openings, form recess and go out the recess opening after, make then half-formed metal sheet by a series of such as known roller die seat that need not to illustrate itself.To sequentially form the edge of a wing, edge 24,104 or 106 and support antelabium 38 or 120 on the opening either side at the roller die on the die holder.
Usually remain unchanged smooth and do not have the upstream of the rotational pressure machine of moulding to finish at band-like plate band-like plate is cut into fixed length.Like this, the every metal sheet that will experience various punching presses, moulding and rolling and forming order is cut into the desired precise length of finished product joist in advance.
According to design, also can joist be cut into fixed length in the downstream of roller die to equipment.
What must remember is, when being cut into fixed length, each end at each joist must leave feed (provision) to stay astomous joist end, it can be supported on the appropriate position in the final floor slab structure like this, while all openings in each joist are crossed this structure and are in alignment with each other.In the joist 20 and 100 in this case, opening 28 is identical with 112, symmetry and make its manufacturing become very easy by the fact that cross rib separates.Joist by this form makes and is cut into the easier enforcement of fixed length.With two back-to-back placements of joist and when opening is in alignment with each other, clearly this will make to install by the facility of opening and be very easy to.
Be assembled in the floor in order to make up haunched member 12, be provided with edge member 14, be shown specifically as Fig. 6 to Fig. 9.
