As shown in fig. 1, an embodiment of the present invention provides a splicing assembly 100 for a guardrail, which is used for splicing and fixing a double-transverse-wire mesh sheet in the guardrail. Specifically, the splice assembly 100 includes a first splice 110 and a second splice 130. Wherein the first splicing element 110 has opposing first 111 and second 113 ends. The first end 111 of the first splicing element 110 has a first cross-filament spacing plug 112, and the side of the first splicing element 110 adjacent to the second end 113 is provided with a first laterally extending overlapping portion 114. The second splicing member 130 is detachably and fixedly connected to the first splicing member 110, and is located at one end of the first end 111 of the first splicing member 110. The second splicing element 130 has a second side-extending lap 131.

Above-mentioned splicing assembly 100, insert first horizontal silk interval plug 112 and locate the interval between the horizontal silk in order to avoid two sets of horizontal silk relative rotations, and first splicing member 110 of fixed connection and second splicing member 130, extend overlap joint portion 131 with the second side through first side extension overlap joint portion 114 and second side respectively and inject two sets of horizontal silk relative position with two sets of horizontal silk overlap joints respectively, can realize the concatenation of two horizontal silk net pieces, compare in the traditional mode of tying up through enamelled metal etc., can effectively reduce two horizontal silk net pieces and lead to the phenomenon that the surface coating easily damaged because of twining many times. More specifically, when the splicing of the double-transverse-wire mesh is realized through the traditional mode of bundling by enamelled metal and the like, the number of winding turns is large, and the contact area between the double-transverse-wire mesh and the double-transverse-wire mesh is small, so that the stress on the wound position of the double-transverse-wire mesh is large, and the double-transverse-wire mesh is easy to damage. In this embodiment, the first side extending overlapping part 114 and the second side extending overlapping part 131 are only overlapped with the two sets of transverse wires, so that the phenomenon of local stress concentration on the surface of the double-transverse-wire mesh caused by multiple winding can be avoided, and the phenomenon that the surface coating is easily damaged can be effectively reduced.

In addition, it can be understood that the two double transverse wire mesh sheets need to be fixed at multiple positions of two opposite groups of transverse wires in a splicing mode. Traditionally, influenced by human factors, the mode of tying up each time is difficult to be completely the same, thereby leading to the phenomenon of messy and unattractive splicing parts and simple and regular structure, and increasing the beautiful effect of splicing. In the application, the splicing of the double-transverse-wire mesh sheets is realized through the splicing assembly 100, the used splicing assemblies 100 are more in number and the same in structure, and therefore the attractive effect of splicing the double-transverse-wire mesh sheets is improved.

In addition, as required, can suitably set up the extension length that first side extends overlap joint portion 114 and second side extension overlap joint portion 131 to avoid first side extension overlap joint portion 114 and second side extension overlap joint portion 131 to surpass the both sides surface of two horizontal silk nettings when the concatenation, thereby avoid people or animal by splice assembly 100 fish tail or scratch when passing by the guardrail side, and can further improve the pleasing to the eye effect of two dead net piece concatenations.

In this embodiment, the second splicing member 130 has a second transverse-filament interval insertion portion 132, and the second transverse-filament interval insertion portion 132 is located at one end of the second splicing member 130 close to the first transverse-filament interval insertion portion 112, so that the second transverse-filament interval insertion portion 132 can also be inserted into an interval between two transverse filaments, thereby better preventing the relative rotation of the two groups of transverse filaments during splicing.

It will be appreciated that in other embodiments, the second splicing element may be provided without the second cross-filament spacing insert, and the two sets of cross-filaments are prevented from rotating relative to each other only by the first cross-filament spacing insert being inserted into the space between the cross-filaments. Optionally, the length of the first transverse wire spacing insertion part is appropriately set, so that the first transverse wire spacing insertion part can be penetrated in the spacing between the two groups of transverse wires, and thus the relative rotation of the two groups of transverse wires can be better prevented.

In this embodiment, the first and second transverse wire

spacing insertion portions

112 and 132 are disposed opposite to each other and have the same size. In another possible embodiment, the first transverse-filament spacing plug and the second transverse-filament spacing plug may also be arranged offset and may also have different sizes.

In this embodiment, along the extending direction a-a of the first transverse wire spacing plug 112, the first splicing member 110 is provided with a first fixing hole 115, and the second splicing member 130 is provided with a second fixing hole 133 matching with the first fixing hole 115, so that the first splicing member 110 and the second splicing member 130 can be detachably connected through bolts or screws. Further, the first fixing hole 115 and the second fixing hole 133 are located at positions opposite to the first lateral wire spacing plug 112 and the second lateral wire spacing plug 132, respectively. Of course, it is understood that in other possible embodiments, the positions of the first fixing hole 115 and the second fixing hole 133 are not limited thereto, and the first splicing member 110 and the second splicing member 130 can be detachably and fixedly connected.

Of course, it can be understood that, in another possible embodiment, the first splicing element and the second splicing element are detachably and fixedly connected without being limited thereto, and the first transverse wire spacing insertion portion and the second splicing element can be detachably and fixedly connected by means of clamping or the like, so as to realize the detachable and fixed connection of the first splicing element and the second splicing element.

In this embodiment, the first splicing element 110 is provided with first side extending overlapping parts 114 on two opposite sides; the opposite two sides of the second splicing member 130 are provided with second side extension overlapping parts 131, so that the two transverse wires in each group of transverse wires are stressed in a balanced manner, and the relative positions of the two transverse wires are kept stable.

In this embodiment, the side of the first splicing element 110 has a first vertical strand abutting side 116, and the second splicing element 130 has a second vertical strand abutting side 135. Thus, when splicing, the first splicing member 110 and the second splicing member 130 can be respectively attached to the vertical wires of the corresponding double-transverse-wire mesh. Therefore, the splicing stability of the two double-transverse-wire meshes can be better realized.

Further, in the present embodiment, the first vertical wire attaching side 116 is coplanar with the second vertical wire attaching side 135. Alternatively, in another possible embodiment, the positions of the first vertical wire attaching side and the second vertical wire attaching side may be set appropriately according to the positions of the vertical wires.

In this embodiment, the first splicing element 110 and the second splicing element 130 are both plastic connectors. It is understood that in other possible embodiments, the first splicing element 110 and the second splicing element 130 are not limited to being formed of plastic materials, but can be formed of other materials.

As shown in fig. 2, another embodiment of the present invention provides a splicing assembly 200, which is different from the splicing assembly 100 in that:

the direction a-a in which the first cross-filament spacing plug 112 extends is the first direction. The first cross-filament spacing insertion portion 112 has a first position-limiting portion 1121, and the second splicing member 130 has a second position-limiting portion 137 matched with the first position-limiting portion 1121, so as to limit the positions of the first cross-filament spacing insertion portion 112 and the second splicing member 130 in the direction perpendicular to the first direction. On one hand, the relative positions of the first splicing element 110 and the second splicing element 130 can be quickly aligned during splicing; in addition, the stability of the fixed connection of the first splicing element 110 and the second splicing element 130 can also be increased.

In this embodiment, the first position-limiting portion 1121 is a position-limiting hole, and the second position-limiting portion 137 is a position-limiting post. It should be noted that, in another possible embodiment, the structures of the first position-limiting portion and the second position-limiting portion are not limited thereto.

As shown in fig. 3, another embodiment of the present invention provides a splicing assembly, which is different from the splicing assembly 100: the first laterally extending lap 114 is disposed around the first splicing element 110. Likewise, a second laterally extending lap is disposed around the second splicing element. And the two transverse wires in each group of spliced transverse wires can be stressed in a balanced manner so as to keep the relative positions of the two transverse wires stable. The structure of the second splicing member is the same as that of the first splicing member 110, and the structure of the second splicing member is not shown, and the structure of the first splicing member 110 may be referred to.

In addition, in the splicing assembly 100, the first transverse wire spacing insertion portion 112 and the second transverse wire spacing insertion portion 132 are both plate-shaped. Unlike the splice assembly 100, in the present embodiment, the first cross-wire spacing plug 112 and the second cross-wire spacing plug are both cylindrical. It will be appreciated that in other possible embodiments, the configuration of the first and second transverse-wire spacing inserts is not limited to plate and cylinder shapes, but may be any other regular or irregular shape.

As shown in fig. 4 and 5, the present invention also provides a guardrail 500 comprising two double transverse wire mesh sheets 510 and a plurality of splicing assemblies 100. One side of each double transverse wire mesh sheet 510 for splicing with the adjacent double transverse wire mesh sheet 510 is provided with a group of transverse wires 511. Each set of transverse wires 511 comprises two transverse wires 511 arranged parallel to each other and spaced apart. Two sets of transverse wires 511 on the corresponding sides of two adjacent double-transverse-wire mesh sheets 510 are arranged oppositely, and are respectively set as a first set of transverse wires 511a and a second set of transverse wires 511 b. In each group of splice assemblies 100, the first side extending strap 114 of the first splice 110 is located on a side of the first set of cross-wires 511 that is distal from the second set of cross-wires 511, the second side extending strap 131 of the second splice 130 is located on a side of the second set of cross-wires 511 that is distal from the first set of cross-wires 511, and the first cross-wire spacing insert 112 is inserted into the space between two cross-wires 511 in the first set of cross-wires 511.

Above-mentioned guardrail 500, insert first horizontal silk interval plug 112 and locate the interval between horizontal silk 511 in order to avoid two sets of horizontal silk 511 relative rotations, and first splicing member 110 of fixed connection and second splicing member 130, in order to extend overlap joint portion 114 and second side respectively and extend overlap joint portion 131 with two sets of horizontal silk 511 overlap joint respectively and prescribe a limit to two sets of horizontal silk 511's relative position, can realize the concatenation of two horizontal silk net pieces 510, compare in the traditional mode of tying up through enamelled metal etc., can effectively reduce two horizontal silk net pieces 510 and lead to the easy phenomenon of damaging of surface coating because of the winding many times. In addition, the splicing of the double-transverse-wire mesh sheets 510 is realized through the splicing assemblies 100, the number of the used splicing assemblies 100 is large, and the structures of the splicing assemblies are the same, so that the aesthetic effect of splicing the double-transverse-wire mesh sheets 510 is improved.

In this embodiment, double horizontal wire mesh sheet 510 has vertical wires 513 perpendicular to horizontal wires 511. A splicing assembly 100 is provided on both sides of one vertical wire 513. Therefore, the splicing of the transverse wire 511 net piece can be more stably realized.

Referring to fig. 1 and 4, in the present embodiment, the first side extension bridge 114 has a first abutting surface 1141 matching with the corresponding transverse filament 511, and the second side extension bridge 131 has a second abutting surface 1311 matching with the corresponding transverse filament 511. Therefore, the first side extension overlapping part 114 and the second side extension overlapping part 131 are in abutting contact with the surface of the transverse wire 511, and the phenomenon of stress concentration is effectively reduced.

In this embodiment, the two double-transverse wire mesh sheets 510 have different structures. It will be appreciated that in other possible embodiments, the two double wire mesh sheets may be of the same construction. In addition, the number of the double-transverse-wire net sheets in the guardrail is not limited to two, and can be more than two.

Optionally, in a feasible embodiment, in two sets of transverse wires where two adjacent double transverse wire mesh sheets are butted, at least one transverse wire is provided with a third limiting portion for limiting the movement of the splicing assembly along the extending direction of the transverse wire, so that the splicing assembly is prevented from sliding along the extending direction of the transverse wire, and the splicing of the two transverse wire mesh sheets is realized more stably.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
