Abstract

The utility model relates to a dense mesh safety vertical net which is used in building sites especially. The mesh structure of the utility model is composed of a set of straight-chain coil strings and transverse latch threads between two adjacent straight-chain coil strings. The utility model is characterized in that at least four transverse latch threads which are divided into two groups and are crossed pairwise; the transverse latch threads are across wound and fixed with the straight-chain coil strings, which can prevent the twist or the expansion of coils. The utility model has the advantages of reasonable design, firm and durable structure, and long service life.

Description

The dense mesh type safety vertical net

The utility model relates to a dense mesh type safety vertical net, is specially adapted to building field, and being used as stands goes along with sb. to guard him net.

A kind of close purpose vertical plastic safety net is disclosed in the CN2130182Y patent, its primary structure is that its wire side is directly to many groups of two and straight chain coil groups are arranged, have between each group and can hold the large-spacing that finger inserts, many groups of two and horizontal door bolt groups are laterally arranged, be across in the space of large-spacing.Horizontal door bolt group is the line of back and forth entwining that is close to and parallels by two, back and forth through between three string straight chain coil strings.The horizontal door bolt group of this structure is unidirectional non-intersect, so the safety net that constitutes is more lax, and mesh more very easily drawn together brokenly by instrument etc., stops that the effect of little sandstone is also desirable not to the utmost.

The purpose of this utility model is that a kind of horizontal door bolt line intersection of design is laid, and is both sturdy and durable, can stop the dense mesh type safety vertical net of tiny sandstone again.

Task of the present utility model is to realize like this, the plastic cement silk of handling through stabilizing agent is plastic net clocklike by form a kind of crisscross of tricot machine braiding, its structure is made up of the horizontal door bolt line between one group of straight chain coil string and the adjacent two straight chain coil strings, it is characterized in that closing at least between adjacent two straight chain coil string locations by two forming four horizontal door bolt lines that intersect in twos.Because horizontal door bolt line adopts the chi structure wiring can prevent the twisting of upright netting twine circle and the excessive expansion of mesh, the soundness of the upright net of influence.

The utlity model has of a tightly knit structurely, sturdy and durable, long service life, and can stop effectively that tiny sandstone drops out outside the net is safeguarded the cleaning of environment and the characteristics of production safety.

Below in conjunction with concrete legend the utility model is described further:

Embodiment one:

This is the horizontal door bolt structure chart of line 2 through adjacent three string straight chain coil strings 1 of back and forth entwining with reference to Fig. 1, knit time formation one-period unit for two of straight chain coil string 1, between adjacent two straight chain coil strings Unit 1, contain two at least and form four horizontal door bolt lines that intersect in twos, the horizontal door bolt line that intersects is to be that another symmetrical line of back and forth entwining that back and forth entwine line and adjacent the 4th straight chain coil string of starting point is starting point forms at interval at straight chain coil string by chain coil string always, its crosspoint 3 all on the interval of straight chain coil string, the half-cell of back and forth entwine line 2 and straight chain coil string 1 also promptly one knit time to entwine and turn back after fixing.

With reference to the weavy grain schematic diagram of the upright net of Fig. 2, straight chain coil string 1 is L ₁₀L is arranged respectively ₁₁, L ₁₂, L ₁₃... L _1n, the line 2 of back and forth entwining is L ₂₀Group and symmetrical L _{20 '}Group has L respectively ₂₁, L ₂₂L _2nAnd L _{21 '}, L _{22 '}L _{2n '}, line L wherein back and forth entwines ₂₂Reciprocal L through straight chain coil string ₁₁, L ₁₂, L ₁₃Between, and at the reciprocal L of break and straight chain coil string ₁₁, L ₁₃One knit time entwine fixing, constraint mutually, and the symmetrical line L that back and forth entwines _{22 '}Reciprocal L through straight chain coil string ₁₂, L ₁₃, L ₁₄Between, and at the reciprocal L of break and straight chain coil string ₁₂, L ₁₄One knit time entwine fixing, constraint each other, line L back and forth entwines ₂₂And L _{22 '}L at straight chain coil string ₁₂, L ₁₃The interval form to intersect horizontal door bolt line, and L ₂₂With L _{21 '}Also become symmetry, and can be at the L of straight chain coil string ₁₁, L ₁₂The interval form to intersect horizontal door bolt line, so interweaving, to form a horizontal door bolt line be the upright net of chi structure.

Embodiment two:

With reference to Fig. 3, this is the weavy grain figure of line 2 through adjacent four string straight chain coil strings 1 that back and forth entwine, its mode of knotting is identical with last example, the straight chain coil string 1 that the line 2 of just back and forth entwining runs through is many more, its reciprocal kinking 2 symmetrical and that can intersect is also many more, and the horizontal door bolt line of the intersection group that forms at the interval of straight chain coil string 1 is also many more.

Embodiment three:

With reference to Fig. 4, this is one back and forth to entwine line 2 through the weavy grain figure of adjacent five string straight chain coil strings 1, its mode of knotting is identical with last two examples, but the straight chain coil string that the line of back and forth entwining runs through is many more, the resistance that moves through inclined to one side eedle head is big more, and influences the life-span of equipment.

Claims

1, a kind of dense mesh type safety vertical net of being made up of the horizontal door bolt line between one group of straight chain coil string and the adjacent two straight chain coil strings is characterized in that containing at least between adjacent two straight chain coil string locations two and forms four horizontal door bolt lines that intersect in twos.

2, dense mesh type safety vertical net according to claim 1 is characterized in that horizontal door bolt line is meant through two horizontal door bolt line sums that the symmetrical line of back and forth entwining constitutes of adjacent three strings or the above straight chain coil string of three strings between adjacent two straight chain coil string locations.

3, dense mesh type safety vertical net according to claim 2, the half-cell of it is characterized in that back and forth entwining line and straight chain coil string is entwined and is fixedly turned back.
