It is welded with a lateral rectangular steel pipe；Four nylon injection-molding universal wheels are separately mounted to four long 80mm, wide 80mm by step 4,
On the steel upper ledge 10 of thick 10mm, then four steel upper ledges 10 are welded on to the quadrangle of steel structure base 4；Step 5, in steel knot
Aperture on the lateral rectangular steel pipe of structure pedestal, the circular hole position alignment of position and steel construction fixed plate, the spiral shell of upside-down mounting diameter 15mm
Bolt 6, one end 4, in addition the washer of corresponding Bolt sizes, the fastening of nut twist-on.
Baffle screen is widely used in several fields, and a kind of common fixed sound barrier installation is as follows, encloses at the construction field (site)
One block of steel plate is welded on sound barrier both ends bottom edge first on rib, steel plate quadrangle is equipped with mounting hole, then by diameter 10mm, length
40mm covers the reinforcing bar of silk rolling, and in foundation forms, the position of four reinforcing bars is adapted to lower end bent anchor with the position of steel plate upper installing hole,
Casting concrete conserves after expiring form removal, sound barrier is mounted in mixed mud, finally to reinforcing bar upper end using corresponding ruler
Very little washer, nut 3 are fastened, and the installation of sound barrier is completed.And conventional baffle screen is on the enclosing side of entire construction site
It requires to be installed in place, can accomplish that the effect made an uproar is cut in comprehensive sound insulation, the manpower material power of investment is many.For example, an if building site
Enclosing unilateral long 200m, wide 20m then need to install sound barrier about 145, need 145 parts of installation steel plates, bent anchor muscle, nut, mix
The materials such as solidifying clay model plate.And the characteristics of movable type baffle screen is flexibly to move and fix, it is wide if the unilateral long 200m in a building site
20m, it is only necessary to which the sound insulation baffle screen that puts into the engineering construction area peripheral edge is calculated by a constructing structure segment length in 20m, substantially
13~20 or so mobile baffle screens need to only be put into.It is mobile baffle screen input amount compared to conventional baffle screen dosage
7 times.Mobile baffle screen not only can reduce cost in investment, and advantage is had more also in recycling.Mobile baffle
It is simple to shield installing and dismounting, and its base dimensions and weight are little, are readily transported preservation.And traditional baffle screen, it is fixed on
On builder's road, it is fixed on hard shoulder to be also fixed on and makes by oneself in concrete foundation.For " pedestal " of conventional baffle screen, substantially
Belong to it is irremovable, or self weight it is especially big, it is difficult to transport save, be easily damaged, the cost of secondary conveying and the cost of preservation
Also relatively high.Mobile baffle screen manpower material power input amount is 1/7 (by the example above) of conventional baffle screen input amount.And from
It is said in recycling, not only can flexibly move, install, dismantle, be also convenient for transport and save, under normal circumstances, mobile sound
It is very small to hinder plate consumption amount, can be recycled for multiple times.Compared to conventional baffle screen, its cost is greatly reduced.
It should be noted that voice described in utility model is synonym for convenience of describing.Above-described embodiment can basis
It needs to be freely combined.The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
