Abstract
The utility model discloses a kind of sound isolating keel for light partition wall, outward appearance is M type, it comprises base plate and two side plates integrated with this base plate, and be configured with at least one trapezoidal groove on which floor plate, wherein the angle on two inclined-planes of trapezoidal groove is 44 degree.The groove that base plate is formed can play damping effect to sound wave, and selects the strip material with specific thicknesses scope, thus improves the sound insulation property of keel.
Description
Technical field
The utility model relates to gypsum plank field, is specifically related to the sound isolating keel for plasterboard partition wall.
Background technology
Thistle board light partition wall is a kind of composite construction, and inside is made up of lightgage steel joist and filling cotton.Existing keel are C type structure, namely by base plate 1 and with it integrated two side plates 2 form, as shown in Figure 1.This keel are not owing to having buffer structure, and the transmission of sound is linear pattern transmission, cause the sound insulation property forming partition wall poor, if will improve the sound insulation factor of body of wall, usually adopt the thickness of the number of plies increasing Thistle board or change Thistle board to realize.
Summary of the invention
The purpose of this utility model is to provide the good sound isolating keel of a kind of sound insulation property.
Open a kind of " M " type sound isolating keel of the utility model, it comprises base plate and two side plates integrated with this base plate, and be configured with at least one trapezoidal groove on which floor plate, wherein the angle on two inclined-planes of trapezoidal groove is 44 degree.Further, the spacing between this biside plate is 75-150 millimeter, is preferably 75 millimeters.Further, the thickness of this side plate and this base plate is 0.5-0.8 millimeter, is preferably 0.6 millimeter.The length of this biside plate is 45-50 millimeter.
Technique effect of the present utility model is, the groove that base plate is formed can play damping effect to sound wave, and selects the material with specific thicknesses scope, thus improves the sound insulation property of keel.

Fig. 3 is the phantom drawing of the sound isolating keel shown in Fig. 2.
Fig. 4 illustrates the contrast sound insulation measurement result of sound isolating keel according to the utility model one embodiment and existing keel.
Detailed description of the invention
Fig. 2 illustrates an embodiment of the present utility model, and sound isolating keel 100 becomes M shape substantially, and it has base plate 110 and two side plates 120 integrated with this base plate 110.
Outstanding feature of the present utility model is provided with trapezoidal groove 130 on base plate 110.Usually, keel use metal steel strap to make.This groove 130 makes these keel have the structure of spring-like, and damping increases and forms damping effect, quickly attenuate sound wave energy to the vibration of sound wave, thus realizes good defening effect.In addition, the trapezoidal sectional shape of groove, while having damping effect, also makes keel still have higher intensity.
It will be appreciated by those skilled in the art that, although base plate is only arranged a trapezoidal groove in the embodiment of this manual, but under the width requirement meeting base plate 110, can more than one trapezoidal groove be set on base plate, thus better defening effect can be obtained.
In a concrete example, the angle being configured to two inclined-planes 132 of trapezoidal groove 130 is 44 degree, and it can obtain good vibration damping defening effect.
In a concrete example, the distance between two side plates 120 of sound isolating keel 100, i.e. the width of base plate 110 can be 75-150 millimeter, is preferably 75 millimeters.
In a concrete example, the thickness range for the sheet metal of sound isolating keel 100 is 0.5-0.8 millimeter, preferably adopts the sheet metal of 0.6 millimeters thick to manufacture sound isolating keel.That is, the thickness of this base plate 110 and side plate 120 is 0.5-0.8 millimeter, is preferably 0.6 millimeter.
In addition, the length of this biside plate 120 is 45-50 millimeter.
The sound insulation measurement result of carrying out according to national standard as shown in Figure 4, make based on on-gauge plate respectively by the comparative sample of employing.According to this test, the comparing result of sample A (ordinary keel+on-gauge plate) and B (sound isolating keel+on-gauge plate) is as shown in table 1.
Table 1
Wherein, C is the correction of weighted pink noise, and Ctr is the correction of weighted traffic noise.
According to the result of above-mentioned test, the sound isolating keel proposed according to the utility model is used to improve 1-2 decibel than using the sound insulation factor of ordinary keel.
In superincumbent description, set forth the details of the technical solution of the utility model, but those skilled in the art can understand, the utility model is not limited to the detail listed by above-described embodiment, but can change in claim limited range.
