Abstract
The invention provides an Omega-shaped keel, comprising a bottom; a first lateral wing is arranged at one end of the bottom and extends perpendicularly to the bottom; a second lateral wing is arrangedat the other end of the bottom and extends perpendicularly to the bottom; and at least one vibration attenuation groove is arranged along the extending direction of the first lateral wing on the bott om; wherein the first lateral wing and the second lateral wing are arranged at the same side of the bottom. The vibration attenuation groove has obvious vibration attenuation effect and improves the sound insulation performance of the Omega-shaped keel.
Description
Technical field
The present invention relates to a kind of omega-shaped keel.
Background technology
At present, 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, Fig. 1 is C type keel cross section view, C type keel are parallel to each other by two strips and constitute in flank 1,2 and bottom surface 3 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 also 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.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of keel that annex just can improve sound insulation property that need not to increase.
In order to address the above problem, the invention provides a kind of omega-shaped keel, comprise: the bottom surface, the perpendicular extension of an end and this bottom surface in the bottom surface is provided with first flank, the perpendicular extension of the other end and described bottom surface in described bottom surface is provided with second flank, and described first flank and second flank are positioned at the same side of described bottom surface; The direction that described first flank extends in upper edge, described bottom surface is provided with at least one vibration damping groove.
Preferably, described vibration damping groove comprises first, second vibration damping wing that is provided with the perpendicular extension in described bottom surface, and described first, second vibration damping wing links to each other by the U type vibration damping wing away from an end of described bottom surface.
Preferably, be respectively arranged with first, second relative aileron of inside projected direction on the end of described first, second flank away from described bottom surface.
Preferably, also be provided with reinforcing rib on described first, second flank and the bottom surface.
Preferably, also be provided with anti-skid structure on described first, second flank.
Preferably, also be provided with engraved structure on described first, second vibration damping wing and the U type vibration damping wing.
The present invention has following advantage:
1, the vibration damping groove damping effect among the present invention is obvious, has improved the sound insulation property of omega-shaped keel of the present invention;
2, the setting of reinforcing rib among the present invention has improved the intensity of omega-shaped keel of the present invention;
3, the setting of shoe among the present invention makes things convenient for omega-shaped keel of the present invention to skid when nailing;
4, also further first, second vibration damping wing and the U type vibration damping wing are carried out the damping property that hollow out improves the vibration damping groove among the present invention, and then improve the sound insulation property of omega-shaped keel of the present invention.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the present invention are described further:
Fig. 1 shows C type keel cross section view schematic diagram;
Fig. 2 shows omega-shaped keel front view schematic diagram of the present invention;
Fig. 3 shows omega-shaped keel vertical view schematic diagram of the present invention;
Fig. 4 shows omega-shaped keel left view schematic diagram of the present invention.
The specific embodiment
Fig. 2 is an omega-shaped keel front view schematic diagram of the present invention; Fig. 3 is an omega-shaped keel vertical view schematic diagram of the present invention; Fig. 4 is an omega-shaped keel left view schematic diagram of the present invention.The invention provides a kind of omega-shaped keel, comprise: comprise bottom surface 6, an end of 6 and the 6 perpendicular extensions of this bottom surface are provided with first flank 4 in the bottom surface, and 6 the other end and bottom surface 6 perpendicular extensions are provided with the same side that second flank, 5, the first flanks 4 and second flank 5 are positioned at bottom surface 6 in the bottom surface; The direction that 6 upper edges, first flank 4 extends in the bottom surface is provided with at least one vibration damping groove 7.Vibration damping groove 7 damping effects among the present invention are obvious, improved the sound insulation property of omega-shaped keel of the present invention.
Below the present invention is done detailed explanation:
As Fig. 2, Fig. 3, shown in Figure 4, present embodiment comprises a vibration damping groove 7 on first, second flank 4,5, bottom surface 6 and the bottom surface 6, this vibration damping groove 7 is made up of first, second vibration damping wing 12,13 and the U type vibration damping wing 14, also is provided with first, second aileron 8,9 on first, second flank 4,5.On first, second flank 4,5 and bottom surface 6, all be provided with reinforcing rib 10.First, second flank 4,5 is parallel, and perpendicular to bottom surface 6.First, second vibration damping wing 12,13 is parallel and perpendicular to bottom surface 6.The thickness of first, second vibration damping wing 12,13 and the U type vibration damping wing 14 can also be reduced, to improve damping property.
Keel in the present embodiment adopt the continuous hot galvanizing steel band, and one-body molded through roll compaction process, its thickness can be between the 0.1-1 millimeter.The keel of present embodiment are flexible strong, have the better damping performance, the energy in the time of effectively cutting down the sound wave transmission behind the composition body of wall, and absorption portion acoustic energy, thus improve sound insulation property.
Be omega-shaped keel sound insulation property test result of the present invention and Mechanics Performance Testing result and the analysis of C type keel performance comparison below.
Table 1: omega-shaped keel and C type keel sound insulation property test result contrast table
In sum; being preferred embodiment of the present invention only below, is not to be used to limit protection scope of the present invention, therefore; all any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
