The sound insulation is consisted of the keel of the utility model, the thistle board, the rockwool plate and so on has more significant sound insulation effect than the other wall body with the same structures, in particular to be at the frequency of 100 to 500Hz.
Description
Technical field
The utility model relates to a kind of keel for building.
Background technology
Keel for building usually constitute lightweight body of wall or furred ceiling with gypsum plank, rock wool etc.Advantage such as the light partition wall in the modern architecture has that cost is low, area occupied is little, easy construction, use are flexible is widely used.
Available technology adopting be a kind of " C " type keel, be parallel to each other and constitute by two strips at the flank that homonymy connects, the defening effect of the body of wall that this keel and gypsum plank, rock wool are formed is limited, especially not good to the defening effect of low frequency range, be difficult to satisfy people have good defening effect to environment such as room, offices requirement.
Can take in practice on " C " type keel, to add the vibration damping bar, utilize multi-layered sheet superimposed, perhaps adopt modes such as two walls are discrete, elasticity connection to improve the defening effect of body of wall, but take these modes can increase the thickness of body of wall, increase cost, construction is got up also cumbersome.
The utility model content
The technical problems to be solved in the utility model provides a kind of annex that need not to increase, and can effectively improve the keel of defening effect.
In order to achieve the above object, the utility model provides a kind of keel for building, first flank and second flank that comprise two strips that are parallel to each other, the first vibration damping wing and the second vibration damping wing that described first flank and second flank do not vertically extend respectively on the rightabout of homonymy, and be connected in vibration damping section between the described first vibration damping wing and the second vibration damping wing opposite side, the wing angles (less angle) that become 100 degree to 170 degree of this vibration damping section and first vibration damping.
Be formed with reinforcing rib on above-mentioned first flank and second flank." L " type reinforcing rib that this reinforcing rib can form for the opposite side at described first flank and second flank, it perhaps is the vertical reinforcing rib of rolling over the yi word pattern that forms down of opposite side at described first flank and second flank, perhaps being the corrugation reinforcing rib that all or part of component surface in the set that described first flank, second flank, the first vibration damping wing, the second vibration damping wing and vibration damping section are formed forms, perhaps is the combination of multiple pattern reinforcing rib.
Can on all or part of member in the set that above-mentioned first flank, second flank, the first vibration damping wing, the second vibration damping wing and vibration damping section are formed, be equipped with pit, to improve intensity.
Angle between the above-mentioned vibration damping section and the first vibration damping wing and the second vibration damping wing can be 120 degree～140 degree.
Above-mentioned keel can be made by light steel building material.
Can be equipped with pit on above-mentioned first flank, second flank, skid when preventing nailing.
When vibration damping keel of the present utility model were used for insulating against sound body of wall or other partiting sound member, the energy in the time of can cutting down the sound wave transmission effectively reached absorption portion acoustic energy, improves defening effect, thereby improves the sound insulation factor of total, staticizes acoustic environment.At the next thickness that can reduce sound insulating structure of the identical situation of defening effect, save cost.

Find out thus, use keel of the present utility model after, therefore after having reduced thickness of wall body, its defening effect is still good than original keel, requires can reduce wall thickness under the identical situation in sound insulation, saves cost.
In order to strengthen the structural strength of two flanks, among second embodiment shown in Figure 3, be formed with the reinforcing rib of " L " type respectively at first, second flank 1 ', 2 ' side.
And in the 3rd embodiment of the present utility model shown in Figure 4, first, second flank 1 "; 2 " then vertically roll over the reinforcing rib that forms yi word pattern down at side, and on cross section, first flank 1 " and second flank 2 " width greater than vibration damping section 5 " projection width on the flank width; can certainly be less than vibration damping section 5 " projection width on the flank width, as long as guaranteeing projection and second flank of described first flank on the width on plane, the second flank place partially overlaps, and overall construction intensity enough gets final product, make the angle between vibration damping section and two the vibration damping wings to adjust flexibly like this, can realize between 170 degree at 100 degree, more 120 degree that are located at are between 140 degree in the practice, and this width relation also can be applicable among other embodiment.
The utility model the 4th embodiment shown in Figure 5 then is formed with corrugation reinforcing rib longitudinally at first, second flank 1 , 2 and vibration damping section 5 surfaces, can certainly only on first, second vibration damping wing the corrugation reinforcing rib be set, to improve the intensity of member.It can certainly be the combination of multiple pattern reinforcing rib
In addition, skid when preventing on keel nailing, can also be on first flank, second flank scutching point.Scutching point also helps the intensity that improves member simultaneously, therefore can be equipped with pit on all or part of member in the set that first flank, second flank, the first vibration damping wing, the second vibration damping wing and vibration damping section are formed.
" Z " of the present utility model type keel are in the sound insulation property that improves the body of wall of being made up of it, and self still has enough structural strengths.The Mechanics Performance Testing result who prior art " C " type lightgage steel joist for building and the utility model " Z " type vibration damping keel (adopting embodiment one) is done according to national standard is as follows.
The static load permanent set of lightgage steel joist for building (body of wall centre keel) is 0.3mm (standard-required is smaller or equal to 2.0mm), and the impact permanent set is 9.4mm (standard-required is smaller or equal to 10.0); And the static load permanent set of Z type vibration damping keel (body of wall centre keel) is 0.2mm, and the impact permanent set is 4.7mm.
In addition, the static load permanent set of lightgage steel joist for building (the horizontal keel of body of wall) is 0.3mm (standard-required is smaller or equal to 2.0mm), and the impact permanent set is 9.4mm (standard-required is smaller or equal to 10.0); And the static load permanent set of the horizontal keel of Z type vibration damping keel adapted is 0.2mm, and the impact permanent set is 4.7mm.
As from the foregoing, the mechanical property of the utility model Z type lightgage steel joist not only meets national standard, but also is better than the C type keel of prior art.
The raising of the utility model defening effect is not limited to other light steel building materials such as adopting galvanized steel plain sheet, cold-rolled steel sheet by its particular structure decision, can also adopt materials such as aluminium extruded sections, PVC section bar, wooden construction to make.The described vibration damping wing extends from flank one side and can refer to extend from edge, also can be from extending near edge, and promptly the vibration damping wing and flank junction can be " " type or T-shape.Therefore, the equivalent variations of being done on the utility model basic structure should be included within the protection domain of the present utility model.
