Abstract

The utility model discloses a dustproof safety screen, which comprises a screen body, reinforcing edges and round buttons with holes, wherein the reinforcing edges are arranged on the periphery of the screen body, and are fixed on the periphery of the screen body via the round buttons with holes, the screen body comprises high-strength mesh layers, PVC and/or polyethylene film layers, the high-strength mesh layers are disposed in the middle of the screen body, and the PVC and/or polyethylene film layers are respectively arranged on two sides of each high-strength mesh layer. The dustproof safety screen which adopts a three-layered structure is waterproof and fireproof, has better wind resistance, impaction resistant strength and transparency, and can reduce dust flying pollution and noise of construction units and further beauty urban environments.

Description

Dustproof safety net

Technical field

The utility model relates to a kind of dustproof safety net, relates in particular to a kind ofly to have strong wind loading rating, strong impact strength, can prevent fires and the dustproof safety net of waterproof.

Background technology

Development along with the city, also made further requirement for city dustless, for beautifying urban environment, reduce unit in charge of construction's dust pollution, reduce noise, embody the aim in " city allow life finer ", especially at the more issuable potential safety hazards of building construction project, for example fire or other pollutions demands developing a kind of Air Filter that has waterproof, fire prevention, minimizing dust pollution, reduces noise urgently.

At present, the Air Filter that has on the market uses common nylon wire to do internal diameter, and plastics face inferior is laid on the surface, in waterproof, fire prevention, dustproof multiple mass discrepancies such as very big environmental protection, safety are arranged.Intensity does not reach the anti-fall coefficient that pulls of safety, brings beyond thought potential safety hazard to engineering construction.

Summary of the invention

The purpose of this utility model is to provide a kind of dustproof safety net, and it is a kind of waterproof, fireproof Air Filter, and it has good wind resistance, impact strength and transparency, can reduce unit in charge of construction's dust pollution and noise, further beautifying urban environment.

The technical scheme that realizes above-mentioned purpose is: a kind of dustproof safety net, comprise dictyosome, wherein, also comprise the stiffened edge that is arranged at around the dictyosome and described stiffened edge is fixed in the latch closure of widening the view around the dictyosome, described dictyosome comprises high strength yarn stratum reticulare in the middle of being positioned at and PVC and/or the polyethylene film layer that lays respectively at each high strength yarn stratum reticulare both sides.

Above-mentioned dustproof safety net, wherein, described high strength yarn stratum reticulare is acrylic fibers silk screen or polyamide fibre silk screen or terylene silk net.

Above-mentioned dustproof safety net, wherein, the scope of the thickness of described PVC layer and/or polyethylene film layer is the 20-60 silk.

Above-mentioned dustproof safety net, wherein, described high strength yarn stratum reticulare be shaped as rectangle.

Above-mentioned dustproof safety net, wherein, described high strength yarn stratum reticulare be shaped as rhombus.

The beneficial effects of the utility model are: the utlity model has following advantage:

1, dictyosome three layer construction has strengthened the wind loading rating and the impact strength of product, and the PVC of high strength yarn stratum reticulare both sides or polyethylene film layer can stop the dust that the building site is inside and outside effectively, make on the dustproof safety net of the present utility model to be difficult for falling ash, is easy to clean; In addition, three layer construction has also stopped the high light on the building site effectively, has reduced the light pollution in building site.

2, the scope of the thickness of PVC, polyethylene film layer is the 20-60 silk, guarantees that product has good transparency.

3, in high strength yarn stratum reticulare and PVC (polyvinyl chloride), polyethylene film layer, add fire-proof flame-retarded agent, can reach good fire protection flame retarding effect.

4, PVC, polyethylene film being taked to take out light handles, make the surface of PVC, polyethylene film layer form matt effect, play the effect that stops that high light sees through, when the strong illumination on the building site on the PVC of inferior light, polyethylene film layer, can produce diffuse reflection, there is not dazzle in the light that promptly reflects, not dazzling; Thereby reduced the light pollution in building site, effectively reduced the influence of light pollution environment and resident living.

5, since the two sides of high strength yarn stratum reticulare all compound PVC and/or polyethylene film layer, make product be easy to clean, be difficult for agingly, damage easily and repair, can recycling after discarded.

6, in manufacturing process, in high-strength silk screen and PVC, polyethylene film, all added fire-proof flame-retarded agent, avoid work progress moderate heat asterism combustion safety net, cause the fire disaster accident; Simultaneously, breaking out of fire accident in the construction plant, safety net can play certain effect that stops diffusion.

This table is the check data of mechanical strength of the present utility model:

By the check data of last table as can be seen, the mechanical strength of the fire safety net of utility model will far surpass the requirement of the national standard (GB16909 1997) of dense mesh type safety vertical net, has very strong wind resistance and impact resistance.

The check data of the combustibility of utility model: (method: GB/T5455-1997):

The check data of the fire resistance of utility model:

By check data as seen, the combustibility of the fire safety net of utility model is poor, and fire resistance is much better than general technical requirements standard; Therefore has good fireproof performance.

Description of drawings

Fig. 1 is the structural representation of dustproof safety net of the present utility model;

Fig. 2 is the structural representation of the dictyosome in the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

See also Fig. 1 and Fig. 2, there is shown a kind of dustproof safety net of the present utility model, comprise dictyosome 1, also comprise the stiffened edge 3 that is arranged at around the dictyosome 1 and the latch closure 2 of widening the view around the dictyosome 1 is fixed on strong limit, dictyosome 1 comprises high strength yarn stratum reticulare 11 in the middle of being positioned at and PVC and/or the polyethylene film layer 12 that lays respectively at each high strength yarn stratum reticulare 11 both sides, the PVC of both sides and/or polyethylene film layer 12 can all adopt the PVC material or all adopt polyethylene film to adopt PVC as a material or a side, opposite side adopts polyethylene film as material, and the scope of their thickness is the 20-60 silk.

High strength yarn stratum reticulare 11 is acrylic fibers silk screen or polyamide fibre silk screen or terylene silk net.

High strength yarn stratum reticulare 11 be shaped as rectangle, also can be rhombus, further improve intensity.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
