It is easy to breakage.
Utility model content
Problem to be solved in the utility model is to provide a kind of protection network with flexibility and elasticity.
In order to solve the above problems, the utility model provides a kind of protection network, including：
More steel wire ropes, mesh sheet is formed for connecting, each steel wire rope is handed over through being continuously bent to form multiple positive and negative S types
The steel wire section replaced；And
Multiple connectors, it is separately positioned in the steel wire section of adjacent two with respect to for convex arc and the part that is in contact
On, to position the steel wire section, the steel wire section of adjacent two is respectively formed a grid cell.
Preferably, the every steel wire rope is bent to form the grid cell of identical quantity.
Preferably, the grid cell corresponding to position socket-connects to form the net in two adjacent steel wire ropes
Piece.
Preferably, the connector is U-shaped card, the opening end of the U-shaped card is equipped with fixing bolt.
The beneficial effect of protection network of the present utility model is, by by steel wire rope through being continuously bent to form multiple positive and negative S
The alternate steel wire section of type, and the specified location of adjacent steel wire section is had into flexible and elasticity net through connector fixation to be formed
Lattice unit, the mesh sheet formed through the grid cell have certain retractility, deformation can be produced so as to reach when mesh sheet is in stress
The effect of energy dissipating buffers, has longer service life compared to common protection network.
Brief description of the drawings
Fig. 1 is the structural representation of protection network of the present utility model.
Fig. 2 is Fig. 1 partial enlarged drawing.
Reference：
1- mesh sheet；2- grid cells；3- connectors；4- steel wire ropes.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model provides a kind of protection network, including：
More steel wire ropes 4, mesh sheet 1 is formed for connecting, wherein each steel wire rope 4 forms multiple positive S through continuous bending
The steel wire section that type and anti-S types alternate, i.e. the steel wire section of the plurality of positive S types and multiple anti-S types alternates；And
Multiple connectors 3, it is separately positioned in two adjacent steel wire sections with respect to on convex arc and the part that is in contact,
With positioning wire section, two adjacent steel wire sections are made to be respectively formed a grid cell 2.That is, as shown in Fig. 2 steel wire by positive and negative S types
Rope is divided into two parts up and down, and two top halfs that adjacent and opening mutually deviates from are connected by connector, similarly, adjacent
And two the latter half mutually deviating from of opening are connected by connector so that adjacent and two top halfs that opening is relative or
The latter half cooperatively forms a grid cell 2.And the formation one mesh sheet unit (ginseng of steel wire rope 4 that should be formed with multiple grid cells 2
See Fig. 1, three mesh sheet units shown in Fig. 1), multiple mesh sheet units are connected to form mesh sheet 1.
Steel wire section due to surrounding grid cell 2 is curved (i.e. S types), therefore with certain stretching, extension surplus, can make net
Piece 1 produces deformation in stress, so as to reach the effect of energy dissipating buffers so that the protection network of the present embodiment compares common protection
Net has longer service life.For example, in 1 non-stress of mesh sheet, each grid cell 2 (should " water droplet " type net in " water droplet " type
Lattice unit includes just putting and being inverted two kinds), and when stretching mesh sheet 1, each steel wire section is stretched as linear pattern (that is, steel wire by arc
Degree of crook under section nature determines its span), now, the grid cell 2 of each droplet-shaped is deformed into rhombus, net
The area increase of piece 1.
Further, the shape after each steel wire rope 4 is bent is identical, i.e., the grid cell 2 of quantity such as is bent to form respectively.Its
In, continuing with Fig. 2, grid cell 2 corresponding to position socket-connects on two adjacent steel wire ropes 4 in mesh sheet 1, that is, is located at
Each grid cell on same root steel wire rope 4 with two grid cell phase hook joints in adjacent steel cord 4 so that each steel wire
Being connected firmly between rope 4, ensure that the bulk strength of mesh sheet 1.When it is implemented, for example can previously prepared more formed with grid
The steel wire rope 4 of unit 2, and be arranged side by side, then can accordingly socket formation successively from bottom to top；Also can first by
Steel cable 4 is bent to form multiple grid cells 2, i.e. the first mesh sheet unit is formed, then by another steel cable
4 successively waveform be located in each grid cell 2 of foregoing steel wire rope 4 to form the second mesh sheet unit, the rest may be inferred, last shape
Into whole piece 1 of throwing the net.The specific preparation method of mesh sheet 1 is not limited to above two method, as long as can prepare to form above-mentioned net
Piece 1, is not repeated excessively herein.
Further, the connector 3 in the present embodiment is U-shaped card, and the opening end of U-shaped card is equipped with fixing bolt.It is preferred that
Ground, the U-shaped card in the present embodiment is galvanizing U-shaped card (a diameter of 7mm-8mm), has galvanizing anticorrosion outer layer, upper zinc amount
More than 340g/m2, the resistance to corrosion for improving U-shaped card of high degree.And because its one end is open and is provided with fixing bolt,
Therefore make the steel wire rope 4 of the applicable different string diameters of this kind of U-shaped card.
Preferably, the U-shaped card in the present embodiment just understands fracture failure, when it fails, protection network when stress is more than 7KN
In flexible mesh unit 2 rectangle is changed into from rhombus, mesh sheet 1 now leans on its own stress of steel wire rope 4 to act in collusion.When by
When power gradually increases above the 90%~95% of the ultimate tensile pulling force of steel wire rope 4, mesh sheet 1 just starts damaged, final rupture occur
Failure.Therefore, not only service life is longer compared to common protection network for the protection network in the present embodiment, and with preferably anti-broken
Damage ability and protection stability, i.e. protection effect are more preferably.
Above example is only exemplary embodiment of the present utility model, is not used in limitation the utility model, and this practicality is new
The protection domain of type is defined by the claims.Those skilled in the art can be in essence of the present utility model and protection domain
It is interior, various modifications or equivalent substitution are made to the utility model, this modification or equivalent substitution also should be regarded as new in this practicality
In the protection domain of type.
