Description

Technical Field

[0001] This utility model belongs to the field of guardrail reinforcement devices, and relates to a guardrail reinforcement device. Background Technology

[0002] Most highway guardrails use rectangular slots installed on both sides of the posts, into which the horizontal bars are inserted. Due to the limited installation distance between adjacent posts, it is inevitable that the horizontal bars will not be inserted sufficiently during installation. Therefore, when subjected to external impact, the horizontal bars can easily detach from the posts, causing them to tilt or fall onto the highway, creating a safety hazard.

[0003] Therefore, this utility model provides a guardrail reinforcement device to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a guardrail reinforcement device. The technical solution adopted includes a post and a crossbar. Rectangular slots are fixedly installed on the left and right side walls of the upper and lower ends of the post. The end of the crossbar is connected by inserting into the rectangular slot. A reinforcement device is provided at the connection between the left and right crossbars and the post. The reinforcement device includes a reinforcement plate. The front and rear reinforcement plates are arranged opposite to each other on the front and rear sides of the connection between the crossbar and the post. The left and right ends of the opposite side of the front and rear reinforcement plates protrude outward to form a first inclined surface. The side of the first inclined surface away from the end of the reinforcement plate protrudes outward to form a second inclined surface. A U-shaped locking groove is movably arranged between the front and rear first inclined surfaces. The left and right U-shaped locking grooves are respectively locked onto the left and right crossbars. The front and rear outer side walls of the U-shaped locking groove are tapered structures that match the front and rear first inclined surfaces. The upper and lower side wall edges of the front and rear reinforcement plates are respectively tightened together by screws.

[0005] As a preferred embodiment of this utility model, limiting blocks are fixedly connected to the left and right sides of the middle of the rear side wall of the front reinforcing plate, and the left and right limiting blocks are respectively snapped into the left and right sides of the column above the left and right rectangular slots; by using limiting blocks, it is convenient to insert the front and rear reinforcing plates into the left and right sides of the column for limiting.

[0006] As a preferred embodiment of this utility model, through holes are symmetrically opened on the upper and lower sidewall edges of the front and rear reinforcing plates.

[0007] As a preferred embodiment of this utility model, the inner walls of the front and rear sides of the U-shaped locking groove are evenly provided with a plurality of tapered protrusions. By using tapered protrusions, it is easy for the U-shaped locking groove to be clamped on the left and right crossbars. Under the clamping of the front and rear reinforcing plates, the U-shaped locking groove is clamped on the left and right crossbars. Under the action of the tapered protrusions, the U-shaped locking groove is clamped on the crossbars to prevent loosening.

[0008] As a preferred embodiment of this utility model, the U-shaped clamping groove is made of alloy steel.

[0009] The beneficial effects of this utility model are as follows: By using the front and rear opposite reinforcing plates, in conjunction with the U-shaped clamping grooves, the left and right U-shaped clamping grooves are respectively clamped onto the crossbars connected to the left and right sides of the column. By tightening the screws on the upper and lower sides of the front and rear reinforcing plates, under the strong support of the front and rear reinforcing plates, the U-shaped clamping grooves are tightly clamped onto the front and rear sides of the crossbars. At the same time, as the clamping force increases, the U-shaped clamping grooves, supported by the front and rear second inclined surfaces, further increase the compressive force between the U-shaped clamping grooves and the crossbars, thereby improving the fastening effect of the device and avoiding the situation where the column and crossbars are easily separated under force in the traditional plug-in connection method.

[0014] Example 1

[0015] like Figures 1 to 3As shown, the guardrail reinforcement device of this utility model adopts the following technical solution: it includes a post 1 and a crossbar 2. Rectangular slots 11 are fixedly installed on the left and right side walls of the upper and lower ends of the post 1. The end of the crossbar 2 is connected by inserting into the rectangular slot 11. A reinforcement device 3 is provided at the connection between the left and right crossbars 2 and the post 1. The reinforcement device 3 includes a reinforcement plate 31. The front and rear reinforcement plates 31 are arranged opposite each other on the front and rear sides of the connection between the crossbar 2 and the post 1. The left and right ends of the opposite side of the front and rear reinforcement plates 31 protrude outward to form a first inclined surface 32. The side of the first inclined surface 32 away from the end of the reinforcement plate 31 protrudes outward to form a second inclined surface 33. The front reinforcement plate... Limiting blocks 34 are fixedly connected to the left and right sides of the middle of the rear side wall of 31. The left and right limiting blocks 34 are respectively snapped into the left and right sides of the column 1 on the upper part of the left and right rectangular slots 11. The upper and lower side wall edges of the front and rear reinforcing plates 31 are respectively symmetrically opened with through holes 35. A U-shaped locking groove 4 is movably arranged between the front and rear first inclined surfaces 32. The U-shaped locking groove 4 is made of alloy steel. The left and right U-shaped locking grooves 4 are respectively snapped into the left and right crossbars 2. The front and rear outer side walls of the U-shaped locking groove 4 are tapered structures that match the front and rear first inclined surfaces 32. Several tapered protrusions 41 are evenly opened on the inner side walls of the front and rear sides of the U-shaped locking groove 4. The upper and lower side wall edges of the front and rear reinforcing plates 31 are respectively tightened together by screws 5.

[0016] The working principle of this utility model is as follows: In use, the column 1 and the left and right crossbars 2 are inserted into the corresponding rectangular slots 11 on the upper and lower sides of the column. Then, the two U-shaped clamping grooves 4 are respectively clamped onto the left and right crossbars 2. Then, the two reinforcing plates 31 are respectively inserted into the left and right sides of the rectangular slots 11 through the left and right limiting blocks 34, so that the U-shaped clamping grooves 4 are respectively located between the front and rear first inclined surfaces 32. After the rear reinforcing plate 31 is reversed, its left and right limiting blocks 34 are inserted into the left and right sides of the lower part of the rectangular slots 11. Then, the screws are respectively passed through the through holes of the front and rear reinforcing plates 31 and locked. With the increase of clamping force and the anti-slip effect of the conical protrusions 41 on the inner sidewall of the U-shaped clamping groove 4, the reinforcing device is firmly locked together with the column 1 and the crossbar 2.
