Technical Field

[0001] The utility model relates to the field of anti-collision guardrail structures, and in particular to a nut-hidden type splicing sleeve and an anti-collision guardrail. Background Art

[0002] At present, anti-collision guardrails are often used in scenes such as roads and bridges to improve relevant safety. Considering that the length of each anti-collision guardrail is limited, it is necessary to adopt a splicing method to meet the length requirements. The existing anti-collision guardrail splicing method often uses bolts and nuts to directly fasten and splice. This method of splicing will expose the bolts and nuts to the view of pedestrians, which greatly affects the appearance. At the same time, the strength of the splicing is also facing challenges. Therefore, it is necessary to provide a high-strength anti-collision guardrail splicing structure that can hide fasteners. Utility Model Content

[0023] DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0025] like Figure 1-2 As shown, the present embodiment provides a splicing sleeve for use on an anti-collision guardrail, which includes: a beam lining 1, a first connecting plate 2, a beam sleeve 4 and a second connecting plate 5. The beam sleeve 4 often has multiple sections to be spliced ​​in actual use. The multiple sections of the beam sleeve 4 of the present embodiment are spliced ​​into a whole through the first connecting plate 2, the second connecting plate 5 and the beam lining 1. Compared with simply connecting the beam sleeves 4 at both ends with fasteners or directly welding them, the solution of the present embodiment can cooperate with fasteners to further improve the strength of the splicing.

[0026] Specifically, the beam lining 1 is installed on the inner side of the beam sleeve 4, the first connecting plate 2 is installed on the inner side of the beam lining 1, and the second connecting plate 5 is installed on the outer side of the beam sleeve 4. The first connecting plate 2, the beam sleeve 4, the second connecting plate 5 and multiple sections of the beam lining 1 are fixed into a whole by fasteners.

[0027] In one embodiment, the length of the beam lining 1, the first connecting plate 2 and the second connecting plate 5 is relatively long, and multiple beam sleeves 4 can be spliced ​​on a section of the beam lining 1, the first connecting plate 2 and the second connecting plate 5 at the same time. In another embodiment, the length of the beam lining 1, the first connecting plate 2 and the second connecting plate 5 is relatively short, and the beam sleeves 4 can be installed at both ends of the beam lining 1, the first connecting plate 2 and the second connecting plate 5 respectively to achieve splicing of adjacent beam sleeves 4.

[0028] In one embodiment, the fasteners are bolts and nuts 3, and a plurality of bolt holes are provided on the beam lining 1, the first connecting plate 2, the beam sleeve 4 and the second connecting plate 5. First, the bolt holes on the beam lining 1, the first connecting plate 2, the beam sleeve 4 and the second connecting plate 5 need to be matched one by one, and then one end of the bolt is passed through the corresponding bolt holes and fastened to the nut 3, so as to fix the beam lining 1, the first connecting plate 2, the beam sleeve 4 and the second connecting plate 5.

[0029] A cavity is provided inside the crossbeam lining 1, and the nut 3 and the first connecting plate 2 are hidden in the cavity, so that from the perspective of pedestrians, they can see the crossbeam sleeve 4 but not the nut 3 and the first connecting plate 2, thereby achieving an aesthetic effect.

[0030] In one embodiment, a slot 6 is provided on the inner side of the beam lining 1, and the first connecting plate 2 is inserted into the slot 6. The slot 6 is formed by two parallel strip-shaped limit blocks extending inward from the inner wall surface of the beam lining 1 on one side where the bolt hole is provided, and the cross-sectional shape of the two strip-shaped limit blocks is set to an L-shaped structure bent toward each other. The first connecting plate 2 is limited in the direction toward the bolt hole by the two L-shaped strip-shaped limit blocks and can only slide along the slot 6. When the bolt is inserted, the first connecting plate 2 will be completely fixed, and the first connecting plate 2 will play a role in increasing the strength of the connection.

[0031] In one embodiment, a second connecting plate 5 can be installed between the end of the bolt away from the nut 3 and the beam sleeve 4, and a plurality of bolt holes for installing bolts are provided on the second connecting plate 5. Multiple sections of the beam sleeve 4 can be spliced ​​and fixed by the second connecting plate 5, and the second connecting plate 5 can further improve the structural strength of the splicing.

[0032] In one embodiment, a groove is provided on one side of the cross beam sleeve 4 close to the second connecting plate 5, and the groove can save material and weight. The bolt hole of the cross beam sleeve 4 is located at the groove. In order to prevent the outer end of the bolt from falling into the groove and causing inconvenience in installation, the width of the groove ( Figure 1 The longitudinal direction in the middle is smaller than the width of the second connecting plate.

[0033] When installing this embodiment, first insert one end of the beam lining 1 into a section of the beam sleeve 4, and ensure that the bolt holes of the beam lining 1 coincide with the bolt holes of the beam sleeve 4, then insert the first connecting plate 2 welded with the nut 3 and the second connecting plate 5 on the outside of the beam sleeve 4, ensure that the hole positions correspond and coincide, tighten with bolts, and then insert the other end of the beam lining 1 into a section of the beam sleeve 4, install it in the same way, and then fix the bolts.
