The specific embodiment
Figure cuts open in the perpendicular three-dimensional office of cuing open structural representation (highly being 6m), local cross-sectional structural representation and the bottom of a kind of double-deck lightgage steel joist noise barrier of the present invention shown in Fig. 1, Fig. 2 and Fig. 3, be clear expression lightgage steel joist structure, the packing material among Fig. 3 is not shown.The double-deck lightgage steel joist noise barrier of the present invention comprises two-layer parallel C type lightgage steel joist skeleton 10, and width is 50mm, 75mm or 100mm.The structure of lightgage steel joist skeleton 10 as shown in Figure 1 and Figure 4, described lightgage steel joist skeleton 10 comprise be fixed in matrix 81 along top keel 11, be fixed in lower substrate 82 along ground joist 12 and be fixed in the frame keel (not shown) of both sides matrix, the described installation frame that consists of light steel dragon 10 along top keel 11, along ground joist 12 and frame keel is so that vertical keel 14, logical installation of passing through keel 15 and lateral keel 16.Described upper matrix 81 is smallpox, and described lower substrate 82 is ground or alley, and described both sides matrix is body of wall or post.
A plurality of vertical keels 14 are described along top keel 11 and along between the ground joist 12 as the two ends, lateral separation are fixedly connected on take 300mm-400mm, described vertical keel 14 is provided with and can passes through the through hole that keel 15 pass for leading to, at least one is logical passes through keel 15 levels and runs through described vertical keel 14 and be connected between the described frame keel, and logical longitudinal separation of passing through keel 15 is 800-900mm.
The two sides of described mesosphere board 20 are affixed and are fixedly connected with by self-tapping screw with described two-layer lightgage steel joist skeleton 10 inboards of vicinity respectively, and surface layer plate 40 is fixedly connected on the outside of two-layer described lightgage steel joist skeleton 10 by self-tapping screw.The height of described mesosphere board 20 and surface layer plate 40 is 2.4m and setting height(from bottom) is identical, and width is 1.2m, and the former thickness is 9.5mm, and latter's thickness is 12mm, and material is Thistle board, magnetic board or calcium silicate board.Because the width of mesosphere board 20 and surface layer plate 40 just in time is 3 times of horizontal spacing of vertical keel 14, the longitudinal edge of each mesosphere board 20 and surface layer plate 40 drops on the vertical keel 14 and by self-tapping screw and is fixedly connected with, transverse edge drops on lateral keel 16(and sees for details hereinafter) upward and by self-tapping screw be fixedly connected with, the edge of the described self-tapping screw described mesosphere board 20 of distance and surface layer plate 40 is 10～20mm.
Described surface layer plate 40 is two-layer, comprises the first surface laminate 40a that is close to described lightgage steel joist skeleton 10 and near the second surface layer plate 40b in the outside.As shown in Figure 2, except the edge was fixed in vertical keel 14, the middle part of each mesosphere board 20 and first surface laminate 40a was fixedly connected with 2 vertical keels 14 by self-tapping screw.On the sustained height, the vertical abutment joint 71 of mesosphere board 20 and the first surface laminate 40a vertical abutment joint 71 of a vertical keel 14, the second surface layer plate 40b and the described first surface laminate 40a vertical keel 14 that mutually staggers that mutually staggers.No matter vertical abutment joint 71(between the levels is mesosphere board 20 or the vertical abutment joint 71 of surface layer plate 40) vertical keel 14 mutually staggers, avoid all vertical abutment joints 71 to drop on the same vertical keel 14, prevent that on the one hand vertical keel 14 load-bearing are excessive, stress is too concentrated and caused distortion, prevent on the other hand mesosphere board 20 and surface layer plate 40 owing under action of gravitation, staggering along vertical abutment joint 71, improve stability.
Described surface layer plate 40 also can be one deck, namely keep described first surface laminate 40a, the cancellation the second surface layer plate 40b get final product.
Described lightgage steel joist skeleton 10 also comprises many row's lateral keel 16, as shown in figures 1 and 3, these lateral keel 16 cross sectional shapes be the C type and with along top keel 11 and identical along ground joist 12 width, the horizontal spacing of the length of each lateral keel 16 and vertical keel 14 is adaptive, multistage lateral keel 16 end to end level connection joint between adjacent described vertical keel 14, thereby shape lateral keel 16 in a row.Connected mode is that pulling rivet connects (every junction is no less than 2 rivets), and mesosphere board 20 is connected with the surface layer plate and is connected with its both sides by self-tapping screw.The arrangement of described lateral keel 16 is as follows: the transverse joint 72 along mesosphere board 20 and surface layer plate 40 arranges the described lateral keel 16 of a row, and every the longitudinal pitch of 600mm-800mm one row's lateral keel 16 is set.Because the height of mesosphere board 20 and surface layer plate 40 is 2.4m, except top and bottom margin and lateral keel 16 are joined, the middle part also is connected with 2 to 3 row's lateral keel 16, strengthen on the one hand the structural strength of lightgage steel joist skeleton 10, can provide support described mesosphere board 20 and surface layer plate 40 on the other hand, reduce stress and concentrate, increase the stability of mesosphere board 20 and surface layer plate 40, avoid highly increasing causing distortion, be conducive to increase height.
Through test, the height of the double-deck lightgage steel joist noise barrier of the present invention can reach 4.5m-6m, and stabilized structure has overcome keel structure because highly increasing the defective of being out of shape; Testing result proves, weighted transmission loss can reach 55-60Db, even next door carries out operation with cutting machine, the level of noise in room still is lower than 45 decibels, effectively deadens sound transmission, has satisfied designing requirement, improves soundproof effect.
