Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated panels, in particular to an environmentally friendly prefabricated panel for road engineering. Background Art

[0002] When carrying out construction work on road projects, environmentally friendly prefabricated panels are a multi-purpose, environmentally friendly, high-quality building material. They are mainly made of cement materials and have the characteristics of being porous, corrosion-resistant and permeable. In addition, environmentally friendly prefabricated panels also have strong compressive strength and are gray in color, making them very suitable for urban road construction.

[0003] When environmentally friendly road engineering prefabricated panels are used for road paving operations in the prior art, it is generally necessary to lift the entire panel through the cooperation of lifting equipment and embedded lifting rings so that it can be accurately laid in place. However, since the lifting rings and reserved lifting holes are integrally formed, and the inner walls of the lifting holes are worn due to repeated impacts by the lifting hooks, the lifting rings become unstable when embedded. This situation will cause the lifting rings to easily detach from the lifting holes and also affect the subsequent normal lifting and paving operations of the entire panel. Therefore, an environmentally friendly road engineering prefabricated panel is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an environmentally friendly prefabricated plate for road engineering, so as to solve the problem proposed in the above background technology that when environmentally friendly prefabricated plates for road engineering are used for road paving work in the prior art, the entire lifting and paving operation is affected due to the unstable internal embedding of the lifting ring.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An environmentally friendly prefabricated board for road engineering comprises a cement prefabricated board body, a hanging hole body is provided on the surface of the cement prefabricated board body, and a plastic inner bushing is provided on the inner side of the hanging hole body, a combined sleeve is threadedly connected to the upper inner side of the plastic inner bushing, and a limiting guide column is fixedly connected to the bottom end of the combined sleeve, a sealing bottom cover is fixedly connected to the bottom end of the limiting guide column, side grooves are respectively provided on both sides of the combined sleeve, limiting blocks are respectively fixedly connected to the lower left and lower right inner sides of the plastic inner bushing, and an embedded hanging ring body is provided on the inner side of the combined sleeve.

[0007] Preferably, a card interface is respectively provided on one side and the front end of the cement precast board body, and a card connection block is respectively provided on the other side and the rear end of the cement precast board body.

[0008] Preferably, the hanging hole bodies are provided with 2 groups in total, and the plastic inner bushings are integrally cast and formed by the hanging hole bodies and the cement precast board bodies.

[0009] Preferably, the inner diameter of the limiting guide column is smaller than the inner diameter of the sealing bottom cover, and the sealing bottom cover and the plastic inner sleeve are matched in size, the sealing bottom cover and the limiting block are adjacent to each other in upper and lower positions, the internal space of the side groove and the outer end of the limiting block are matched in shape, the internal space of the plastic inner sleeve is thin at the top and thick at the bottom, and the interior of the plastic inner sleeve and the interior of the combined sleeve are connected.

[0010] Preferably, the limiting block is slidably connected to an elastic block at one side thereof close to the limiting guide column, and a spring is provided at one side inside the limiting block, the spring and the elastic block are fixedly connected, and the outer surface of the limiting guide column is provided with a slot which is engaged with the elastic block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by providing a combined sleeve, an embedded lifting ring body, a limiting guide column and a sealed bottom cover, it is convenient for the environmentally friendly road engineering prefabricated plate to be able to realize the paving construction operation in the process of splicing and paving operation by hoisting. Under the connection cooperation of the plastic inner liner, the detachable lifting ring structure composed of the combined sleeve, the embedded lifting ring body, the limiting guide column and the sealed bottom cover is stably connected with the hook to cooperate with the plate.
