The specific embodiment
Cut open figure with the perpendicular three-dimensional office of cuing open structural representation (being highly 6m), local cross-sectional structural representation and the bottom of a kind of double-deck lightgage steel joist noise barrier of the utility model shown in Fig. 3 as shown in Figure 1, Figure 2, for the clear lightgage steel joist structure that represents, the packing material in Fig. 3 is not shown.The double-deck lightgage steel joist noise barrier of the utility model 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 on matrix 81 along top keel 11, be fixed on lower substrate 82 along ground joist 12 and be fixed on the frame keel (not shown) of both sides matrix, described along top keel 11, along ground joist 12 and frame keel, form the installation frame of light steel dragon 10, 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.
It is described along top keel 11 and along between ground joist 12 as two ends, lateral separation are fixedly connected on that a plurality of vertical keels 14 be 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 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 contiguous described two-layer lightgage steel joist skeleton 10 inner sides 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 the 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 is just in time 3 times of horizontal spacing of vertical keel 14, the longitudinal edge of each mesosphere board 20 and surface layer plate 40 drops on vertical keel 14 and by self-tapping screw and is fixedly connected with, transverse edge drops on lateral keel 16(and refers to below) to go up and be fixedly connected with by self-tapping screw, 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 and is close to the first surface laminate 40a of described lightgage steel joist skeleton 10 and the second surface layer plate 40b in close outside.As shown in Figure 2, except edge is fixed on vertical keel 14, the middle part of each mesosphere board 20 and first surface laminate 40a is fixedly connected with 2 vertical keels 14 by self-tapping screw.On 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 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 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 that on the other hand mesosphere board 20 and surface layer plate 40 are owing to staggering along vertical abutment joint 71 under the effect of gravity, improve stability.
Described surface layer plate 40 also can be one deck, retains described first surface laminate 40a, cancels the second surface layer plate 40b.
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 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 its both sides by self-tapping screw with surface layer plate 40.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, middle part is also 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, fall stress concentration, increase the stability of mesosphere board 20 and surface layer plate 40, avoid highly increasing and causing distortion, be conducive to increase height.
Through test, the height of the double-deck lightgage steel joist noise barrier of the utility model can reach 4.5m-6m, and stabilized structure has overcome keel structure because highly increasing the defect of being out of shape; Testing result proves, weighted transmission loss can reach 55-60Db, even if next door carries out operation with cutting machine, the level of noise in room, still lower than 45 decibels, effectively deadens sound transmission, has met designing requirement, improves soundproof effect.
