Description

Dust screen easy to install and recover

Technical Field

The utility model relates to a construction technical field especially relates to an easily install and dust screen of retrieving.

Background

In the building construction process, various material piles which easily cause dust emission, such as exposed earthwork, exposed building materials, exposed building garbage and the like, are often required to be stacked in the open air, and if the material piles are not fixed, the dust emission can be caused, and the material waste and the secondary pollution can be caused because passerby, wild animals and the influence of severe weather are disordered after the construction is stopped.

At present in the work progress, mainly adopt the mode of covering the dust screen on the material pile to fix the material pile, the common scaffold protection network on the land is usually selected to the dust screen, this kind of net is made into by the plastics silk, and the wearability is very poor, uses will soon be worn out on the ground, and local breach can quick diffusion in use, just makes whole dust screen unable use very soon. In addition, the dust screen is easy to be stirred into a ball like a rope, and brings much trouble to laying and recycling work.

The Chinese hard sail is unique sail clothes in China, and is endowed with a regular shape by adding a transverse supporting bone to the sail, so that the sail can be lifted and fallen by only one rope, the problem that the lifting and falling of the sail are very troublesome due to the entanglement of the sail and the rope like the western soft sail is solved, and the use in strong wind is not influenced. In addition, the laceration on the Chinese-style sail is limited between the supporting bones and cannot spread. The sails used by modern sailing boats mostly adopt Chinese-style hard sails.

SUMMERY OF THE UTILITY MODEL

FIG. 2 is a top view of a dust screen of the present invention that is easy to install and retrieve;

wherein, the net comprises 11-hard frames, 12-soft frames, 2-net cloth, 21-soft ribs, 3-net retracting ropes and 4-ground nails.

Detailed Description

As shown in fig. 1-2, an easy-to-install and easy-to-recover dust screen, which is covered on a material pile, comprises a rectangular mesh fabric 2 and four side frames arranged at the edges of the mesh fabric 2 and connected with the mesh fabric 2, wherein the side frames comprise two oppositely arranged hard side frames 11 and two oppositely arranged soft side frames 12;

be provided with soft rib 21 between two soft frames 12, soft rib 21 sets up along soft frame 12 length direction interval, and both ends are connected with soft frame 12 respectively, and the side pastes to lean on screen cloth 2 to set up and be connected with screen cloth 2. The use of soft ribs 21 rather than hard ribs is used here because the pile is generally conical in shape and cannot be bent over the entire pile if hard ribs are used. The soft ribs 21 can be made of PVC plastic strips with the diameter of about 1 mm or silica gel strips, but have certain cold resistance and weather resistance if necessary. Otherwise, the dust screen becomes hard due to low temperature/aging, and the laying of the dust screen is not facilitated. For the same reason, the soft frame 12 and the soft rib 21 are made of the same material.

The soft frames 12 are wavy, the net retracting cables 3 are respectively arranged on the two soft frames 12, one ends of the net retracting cables 3 are anchored on one hard frame 11, and the free ends of the net retracting cables 3 sequentially penetrate through the middle points of the adjacent wave crests and wave troughs of the soft frames 12 and extend towards the other hard frame 11. The net retracting rope 3 is similar to a sail retracting rope on a Chinese hard sail, the whole dustproof net can be retracted only by pulling, and the dustproof net can be wound on a roll of the whole dustproof net to prevent the dustproof net from being scattered after being retracted.

The free end of the net retracting rope 3 is provided with a knot for preventing the net retracting rope 3 from falling off the soft frame 12, and a nut can be tied.

The connecting points of the soft frame 12 and the net retracting rope 3 on each side and the connecting points of the soft frame 12 and the net retracting rope 3 on the other side are in one-to-one correspondence and are connected with each other through soft ribs 21. The soft ribs 21 are arranged in this way in order to reinforce the locations where the soft frames 12 are penetrated by the reeving cords 3.

The hard frame 11 is anchored on the ground through the ground nail 4, and in the embodiment, the ground nail 4 is a U-shaped ground nail 4.

The screen cloth 2 of the dustproof screen can be a round wire dense mesh screen, and the soft ribs 21 are woven on the screen cloth 2, so that the round wire dense mesh screen is cheap and easy to obtain; double-layer non-woven fabrics can also be selected, the soft ribs 21 are arranged between two layers of non-woven fabrics of the mesh fabric 2 and are connected with the mesh fabric 2 in an adhesive joint mode, and the non-woven fabrics are more wear-resistant than round-wire dense mesh fabrics.

The utility model relates to an easily install and dust screen of retrieving can single use, installation when single use, including following step:

the method comprises the following steps: the net retracting rope 3 is released, and the hard frame 11 anchored with the net retracting rope 3 is anchored on the ground by the ground nail 4;

step two: grasping the other hard frame 11 to expand the mesh cloth 2 and wrapping the material pile;

step three: anchoring the grasped hard frame 11 on the ground by using the ground nail 4;

during recovery, the dust screen can be recovered like a sail by pulling the ground nail 4 and pulling the net retracting rope 3, and the net retracting rope 3 is wound on the whole roll of dust screen after recovery, so that the dust screen is prevented from being scattered.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
