For the environmental protection purpose of increasingly stringent, people begin to adopt some dust suppression technical measures, mainly are to build the super large storehouse to deposit industry or building, life raw material, discarded object or the rubbish that is easy to generate airborne dust, or build windbreak to keep out the wind.

In addition,, also environment wind-force is had upper limit requirement in some other occasion, for example rattle, during badminton, wind can influence the track of ball, therefore will build table tennis training hall, feather arena etc., to create calm or the light breeze environment.

Yet, no matter be room, venue or the employing windbreak technical measures of building sealing, because the body of wall of these two kinds of schemes all adopts solid wall at present, be to utilize solid wall that windage is blocked to make wind speed moment reduce to zero,, can resist blast for making body of wall so body of wall will bear huge blast, certainly will increase thickness of wall body and increase the ground degree of depth, form heavy body of wall, cause that this entity windbreak has high input, the construction period is long, and build and to move with regard to becoming permanent construction after finishing.

The utility model content

At the defective that existing windbreak has high input, construction period is long, the purpose of this utility model is to provide a kind of light-duty checking wall, and the light cost of this wall weight is low, and is convenient to move.

The utility model adopts following technical scheme: a kind of light-duty checking wall, comprise one or more layers net sheet and many group installing and locating parts, and described installing and locating part comprises column, the stretch-draw of described net sheet is on column.

Described installing and locating part also comprises the wall pier member, and described column is mounted on the wall pier member, is positioned at the net sheet on the wall pier member and facings the wind or/and a leeward side also is equipped with diagonal brace drag-line bar, and diagonal brace drag-line bar upper end is fixed on the described column column support is held.

Described wall pier member upper edge net sheet installation direction is provided with vertical slot, is inserted with sheet material and forms solid wall in slot, and described net sheet is positioned at the sheet material top.

Light-duty checking wall of the present utility model, be not directly all to stop wind windproof, but make wind-force and wind speed reduction reach the checking effect by the net sheet by the resistance of net sheet, employing is defeated a force with a tenderness, the design principle of dividing and rule designs, by once or step by step reducing wind-force up to the wind-force that does not produce airborne dust or till being reduced to the wind-force value that to use, adopting net sheet checking to have with respect to solid wall throws inferior lacking, build fast, lightweight advantage, and can form with the installing and locating part and to be convenient to dismantle the structure that can reuse and be easy to move, need the occasion of calm or gentle breeze applicable to dust suppression place or other.

Description of drawings

Fig. 1 is the structural representation of light-duty checking wall of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments light-duty checking wall of the present utility model is described further, to help understanding content of the present utility model.

As shown in Figure 1, be the structural representation of a kind of light-duty checking wall of the present utility model, comprise net sheet 10,20 and installing and locating part, the checking net is made of two layers of mesh sheet 10,20.The installing and locating part comprises a plurality of wall pier members 1 and column 3, and column 3 is installed on the wall pier member 1, and 10,20 stretch-draw of net sheet are on column 3.Column 3 can be inserted in the vertical core on the wall pier member 1 so that dismounting perhaps is cast in the wall pier member 1, or otherwise fixing.The member that wall pier member 1 can be made for cement components or metal, stone material, organic material is so that move.

Used net sheet 10,20 can adopt wire lath, preferably adopts the high-strength polyester material to weave the flexible net that forms, and to reduce material weight, is convenient to be cut into required size according to the application scenario.

Though net sheet the 10, the 20th, ventilation structure, the effect of wind-engaging power is much smaller than solid wall, but wind speed still can produce big pulling force when big, for the stress-bearing capability that improves member prevents column 3 flexural deformations, be positioned at net sheet 10 on the wall pier member 1 and with a leeward side two diagonal brace drag-line bars 4 be housed also down with the wind, diagonal brace drag-line bar 4 upper ends are fixed on the differing heights of column 3.By increasing one or multi-channel diagonal brace drag-line bar in the main stress direction and increase the stress-bearing capability of column, material is subjected to force direction all to adjust to the force direction that is subjected to that support draws to improve the functional performance of material.Diagonal brace drag-line bar 4 can be rod member or rope spare.

The height of checking wall is decided according to the concrete occasion of using, and for example decides according to the rickyard piling height, and the height that makes the checking wall greater than feed height to a certain degree.The bottom of checking wall is subjected to the influence of wind-force less, therefore for higher checking wall, as shown in Figure 1, installation direction at wall pier member 1 upper edge net sheet 10,20 is provided with vertical slot, in slot, be inserted with sheet material 2 and form solid wall, net sheet 10,20 is positioned at the top of sheet material 2, and sheet material 2 tops are 1500-2000mm apart from ground level.This structure is because the installation site height of net sheet 10,20, can prevent the destruction that artificial or animal or other reason cause, and the suppression effect of sheet material makes body of wall have enough weight and center of gravity low, and stability is better.

As can be seen from Figure 1, the cross section that sheet material 2 is inserted in part in wall pier member 1 slot is big top and small bottom shape, and the size of slot and shape and sheet material 2 coincide.This compound mode can be dismantled, but its structure has kept stable again, the enclosure wall good integrity that surrounds after the grafting, and sheet material is obstructed upwards directly to be extracted, and is difficult for destroyed and damage.Sheet material 2 can be cement board, advantageously adopts light weight board.

The checking ability of checking net depends on its percent opening, and the low more checking effect of percent opening is good more, and it is stressed strong more but its windage is big more.Therefore the percent opening of every layer of checking net is unsuitable too high or too low.The sky rate of opening of every layer of checking net adopts and reduces environment wind-force 30%～60% desired data value and weaves, and determines the number of plies according to the maximum wind power of use occasion, till wind-force being reduced to the wind-force value that the wind-force value that can not produce a dirt maybe will use.Usually percent opening is good with 40-60%.
