Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement construction technology, specifically to a construction device for wear-resistant asphalt pavement. Background Technology

[0002] Wear-resistant asphalt pavement refers to various types of pavement made by mixing road asphalt materials into mineral materials and then paving and compacting asphalt concrete. The asphalt binder of this type of pavement significantly enhances the resistance of the paving aggregate to damage caused by traffic and natural factors, ensuring the pavement is smooth, dust-free, impermeable, and durable.

[0003] When constructing asphalt pavement, the asphalt concrete material needs to be compacted. Since there is no lateral support at the road edge, the compaction and thickness of the road edge are often insufficient, and the road surface linearity is poor. This results in a large longitudinal joint width, causing unnecessary waste. Utility Model Content

[0006] The side mold structure includes a channel steel profile, a pin, a side baffle, and an adjusting screw. The side baffle is hinged to the left side of the channel steel profile via the pin. The side baffle has a waist-shaped hole, and the channel steel profile has a round hole. The adjusting screw passes through the waist-shaped hole and the round hole in sequence. A limit nut and a fastening nut are threadedly connected to the adjusting screw, with the limit nut close to the waist-shaped hole and the fastening nut close to the round hole.

[0007] Furthermore, the left side of the channel steel profile is provided with a first hinge hole, the top of the side baffle is provided with a second hinge hole, and the pin is inserted into the first hinge hole and the second hinge hole, so that the side baffle is hinged to the channel steel profile.

[0019] Please see Figures 1-3 This utility model discloses a construction device for wear-resistant asphalt pavement, including a side formwork structure 1 and ground nails 2. The right side of the side formwork structure 1 is provided with an ear hole 11, and the ground nails 2 are fitted into the ear hole 11. The structure is simple and easy to use. The side formwork structure 1 is fixed to both sides of the road by the ground nails 2, so that the side baffle 14 is in contact with the edge of the asphalt, thereby providing sufficient lateral support and sufficient lateral stiffness. This ensures that the edge of the asphalt remains straight and does not deform when paving and compacting the asphalt pavement. At the same time, the side baffle 14 adopts an adjustable design, which makes it convenient to form a certain paving slope at the edge of the asphalt according to the needs of on-site construction.

[0020] The side mold structure 1 includes a channel steel profile 12, a pin 13, a side baffle 14, and an adjusting screw 15. The side baffle 14 is hinged to the left side of the channel steel profile 12 via the pin 13. The side baffle 14 is provided with a waist-shaped hole 16, and the channel steel profile 12 is provided with a round hole 17. The adjusting screw 15 passes through the waist-shaped hole 16 and the round hole 17 in sequence. A limit nut 18 and a fastening nut 19 are threadedly connected to the adjusting screw 15, with the limit nut 18 close to the waist-shaped hole 16 and the fastening nut 19 close to the round hole 17.

[0021] Specifically, the left side of the channel steel profile 12 is provided with a first hinge hole 110, the top of the side baffle 14 is provided with a second hinge hole 111, and the pin 13 is inserted into the first hinge hole 110 and the second hinge hole 111, so that the side baffle 14 is hinged to the channel steel profile 12.

[0022] In this embodiment, the first hinge hole 110 and the second hinge hole 111 are both assembly structures used for the installation and fixing of the pin 13.

[0023] Specifically, the side baffle 14 is U-shaped, and the waist-shaped hole 16 is opened on the right side wall of the side baffle 14.

[0024] In this embodiment, the oblong hole 16 is used to connect fasteners such as bolts and nuts, providing the necessary connection strength and stability.

[0025] Specifically, the channel steel profile 12 is provided with a diagonal brace 112, and the diagonal brace 112 has a through hole 113.

[0026] In this embodiment, the diagonal brace 112 forms a spatial truss structure, which can effectively improve the overall rigidity of the channel steel profile 12 and prevent the structure from deforming under stress. The through hole 113 is a relief structure to facilitate the installation of the adjusting screw 15.

[0027] Specifically, the right side wall of the channel steel profile 12 is provided with an inclined surface 114, and the circular hole 17 is opened on the inclined surface 114.

[0030] In this embodiment, the ear hole 11 is a fixed structure. After the ground nail 2 is inserted into the ear hole 11, the ground nail 2 is driven into the road surface with the help of tools such as a hammer, thereby fixing the side formwork structure 1 to both sides of the road.

[0031] In use, the structure is simple and easy to use. The side mold structure 1 is fixed to both sides of the road by the ground nails 2, so that the side baffle 14 is in contact with the edge of the asphalt, thereby providing sufficient lateral support and lateral stiffness. This ensures that the edge of the asphalt remains straight and undeformed during paving and compaction of the asphalt pavement. At the same time, the side baffle 14 adopts an adjustable design. That is, loosen the limit nut 18 and the fastening nut 19, and then pull the adjusting screw 15 to move the side baffle 14 inward, thereby adjusting the tilt angle of the side baffle 14 (the adjustable angle range set by this utility model is between 0° and 30°), which makes it convenient to form a certain paving slope at the edge of the asphalt according to the needs of on-site construction.

[0032] In summary, the construction device for this wear-resistant asphalt pavement is simple in structure and easy to use. The side formwork structure 1 is fixed to both sides of the road by ground nails 2, so that the side baffle 14 is in contact with the asphalt edge, thereby providing sufficient lateral support and lateral stiffness. This ensures that the asphalt edge remains straight and undeformed during paving and compaction. At the same time, the side baffle 14 adopts an adjustable design, which makes it convenient to form a certain paving slope at the edge of the asphalt according to the needs of on-site construction.
