Description

Technical Field

[0001] The utility model belongs to the technical field of highway engineering, and more specifically, particularly relates to a pavement overlap structure. Background Art

[0002] Pavement overlap refers to a treatment method in which the newly paved road is overlapped on the old road at the junction of the new and old roads, aiming to achieve seamless connection with the old road and avoid obvious breaks and unevenness. This treatment method is particularly suitable for connecting two different road surfaces. Through specific construction techniques and materials, a smooth transition between the new and old road surfaces is ensured, thereby improving the durability and safety of the road.

[0003] Application No. CN202320184530.0 The utility model discloses a pavement overlap structure, which relates to the technical field of road construction, and solves the problem that the existing roadbed overlap structure does not have any stress tensioning structure after overlap, so that cracks are prone to appear at the overlap position when the road is used in the future, affecting the normal use of the road and the passage of people and vehicles. It includes a cement roadbed, a road asphalt layer is provided on the top of the cement roadbed, and overlap components are installed at the overlap positions of the two cement roadbeds. The overlap component can apply tensioning stress to the two cement roadbeds at the overlap position, so that the two roadbed connection parts can be tightly and stably fitted for use, avoiding the phenomenon of cracks appearing when the road is used later.

[0004] Based on the search of the above patent and the application of an existing pavement overlap structure, it is understood that currently in the process of overlapping the new pavement and the old pavement, most of the overlapping positions are covered with asphalt, which makes it inconvenient to check whether there is any deviation in the overlapping position in the future. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a pavement overlap structure to solve the problem that in the existing process of overlapping a new pavement and an old pavement, most of the overlapping positions are covered with asphalt, which makes it inconvenient to check whether the overlapping positions are offset in the future.

[0006] The technical solution adopted by the utility model is:

[0007] A pavement lap joint structure includes a lap joint seat A; the front end position of the lap joint seat A fits with the rear end position of the lap joint seat B, a support plate A is respectively provided on both sides of the upper interior of the lap joint seat A, and each support plate A has two threaded holes, a limit seat is fixedly connected to the middle position of the interior of the lap joint seat A, the upper front end position of the limit seat is a raised design, and the raised position of the limit seat is rotatably connected to a rotating arm, the middle front end position of the rotating arm is rotatably connected to a rotating shaft, through holes are provided on both sides of the rotating shaft, and U-shaped limit members are inserted into the through holes on both sides of the rotating shaft.

[0008] According to an embodiment of the utility model, threads are provided on both sides of the rear end of the limiter, and two nuts are installed on the threaded positions on both sides of the rear end of the limiter, and the two nuts on both sides of the limiter are located at the front and rear ends of both sides of the rotating shaft.

[0010] According to an embodiment of the present invention, a support plate B is respectively disposed at both sides of the upper inner portion of the bridging seat B, and each support plate B is provided with two threaded holes.

[0011] According to one embodiment of the utility model, the rear ends of the two carrying boards B are respectively fitted with the front ends of the two carrying boards A, the upper ends of the lap seats A and B are covered with a connecting plate, and the two sides of the rear end of the bottom of the connecting plate are fitted with the tops of the two carrying boards A.

[0012] According to one embodiment of the utility model, the two sides of the front end of the bottom of the connecting plate are fitted with the top positions of the two supporting plates B, and four matching holes are opened on both sides of the top of the connecting plate. The matching holes of the connecting plate correspond to the threaded holes of the two supporting plates A and the two supporting plates B.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The rotating arm drives the entire rotating shaft to move forward, so that the limit piece can be sleeved in the groove position at the front end of the frame. At this time, the rotating arm is rotated and reset, and the limit piece moves backward to exert traction on the frame. There is a pulling force between the overlapping seat A and the overlapping seat B for overlapping and fixing.
