The prefabricated pedestrian walkway 100 is laid on the ground and is used to replace the existing ceramic tile paved pedestrian walkway. The drainage design can avoid the accumulation of water on the sidewalk.

[0028] Specifically, the prefabricated walkway 100 includes a sidewalk panel 10 and a drainage pipe gallery 20. The drainage pipe gallery 20 is provided with a drainage groove 20a, which is embedded under the ground. The sidewalk panel 10 can be laid on the ground or erected above the drainage groove 20a. In order to make the drainage pipe gallery 20 invisible on the ground, the sidewalk board 10 is provided with a first groove 10a, and when the sidewalk board 10 is laid on the ground, the first groove 10a of the sidewalk board 10 communicates with the drainage groove 20a, so that the first groove 10a is connected to the drainage groove 20a. Rainwater in a gutter 10a can enter into the gutter 20a.

[0029] please continue figure 2 , the sidewalk board 10 may include a main beam plate 110 and a supporting foot 120, the main beam plate 110 may have a first end surface 110a and a second end surface 110b arranged oppositely, the first end surface 110a is a pedestrian walking surface, and the supporting feet 120 are provided with a plurality of , a plurality of legs 120 are arranged on the second end surface 110b of the main beam plate 110 at intervals, so that the main beam plate 110 and two adjacent legs 120 are encircled to form a first groove 10a, and a plurality of sidewalk plates 10 are arranged side by side When placed, a second groove 10b is formed between two adjacent legs 120 of two adjacent sidewalk boards 10, the second groove 10b is communicated with the drainage groove 20a, and the first groove 10a and the second groove 10b can serve as The function of the drainage channel is to discharge the rainwater in the first groove 10a and the second groove 10b into the drainage groove 20a of the drainage pipe gallery 20 .

[0030] The main beam plate 110 and the support feet 120 may be integrally formed. In a specific embodiment, the main beam plate 110 and the supporting feet 120 may both be formed by pouring concrete. The concrete may be ordinary concrete, or any one of self-compacting concrete, high-performance concrete, and ultra-high-performance concrete. The use of self-compacting concrete, high-performance concrete, and ultra-high-performance concrete can avoid the vibrating operation of the concrete when manufacturing the sidewalk slab 10, and make the manufactured sidewalk slab 10 have a higher service life.

[0031] Reinforcing steel cages may be arranged in the main beam plate 110 and the supporting feet 120, so that the sidewalk plate 10 can have better structural rigidity. It can be understood that when a reinforced steel cage is provided, since the reinforced steel cage hinders the vibration, in order to avoid the vibration operation, any one of self-compacting concrete, high-performance concrete, and ultra-high-performance concrete can be used to cast and form. .

[0032] In the illustrated embodiment, the main beam panel 110 is in the shape of a rectangular panel, which will facilitate the splicing of the sidewalk panel 10 . It can be understood that the shape of the main beam plate 110 can also be other shapes. For example, when a sidewalk with a curve needs to be laid, the main beam plate 110 at the corner can have the same or different shapes. For example, the main beam plate 110 can be It is a fan-shaped structure with the same or different central angles.

[0033] In a specific embodiment, in order to prevent large-sized items from falling into the first groove 10a or the second groove 10b, thereby blocking the first groove 10a or the second groove 10b, both sides of the main beam plate 110 may be The stepped structure (not shown) is formed by extension or indentation, and the stepped structure 111 between two adjacent sidewalk boards 10 is adapted, so that the adjacent sidewalk boards 10 are embedded with each other, which can prevent large-sized items from entering the first floor. Inside a trench 10a or a second trench 10b.

[0034] Those skilled in the art can understand that the communication between the first groove 10a and the drainage groove 20a may be direct communication or indirect communication. For example, when the sidewalk boards 10 are placed side by side, the first grooves 10a and the drainage grooves 20a are directly connected, and when the sidewalk boards 10 are laid such that the first grooves 10a are parallel to the drainage grooves 20a and the first grooves 10a are directly connected to the drainage grooves 20a When both are connected, the first groove 10a parallel to the drainage groove 20a will indirectly communicate with the drainage groove 20a.

[0035] In order to make the sidewalk board 10 be placed on the ground smoothly, the feet 120 may have a suitable width. The placement of the feet 120 may also have suitable locations. For example, when there are two supporting legs 120, the main beam plate 110 can be divided into quarters along the width direction, and the supporting legs 120 can be disposed at positions corresponding to one-quarter and three-quarter equal parts of the main beam plate 110. Therefore, the sidewalk board 10 can have better balance.

The lifting needle 125 can realize the mold release of the sidewalk board 10 in the manufacturing stage, and also facilitate the lifting and installation during transportation and installation, which can reduce the construction process and improve the installation efficiency. By arranging the counterbore 123 and the hanging needle 125 on the outer side wall 121 of the support leg 120, the countersunk hole 123 and the hanging needle 125 are hidden, and the appearance of the product is improved. The problem of a large gap between two adjacent sidewalk boards 10 may be caused when the main beam board 110 is on the side.

[0037]The arrangement of the countersunk holes 123 and the hanging pins 125 can also play a guiding role for the laying of the sidewalk board 10 on the ground, so that the sidewalk board 10 is laid in a preset shape. The prefabricated walkway 100 may further include a connecting piece (not shown), two ends of the connecting piece are respectively inserted into the countersunk holes 123 of the two sidewalk boards 10 to guide the laying of the sidewalk boards 10 . For example, when it needs to be laid in a straight line, the length of the connecting piece can be adapted to the distance between the two adjacent legs 120 of two adjacent sidewalk boards 10, and the two ends of the connecting piece are inserted into the two adjacent sidewalk boards 10. In the countersunk holes 123 of two adjacent legs 120, when the number of countersunk holes 123 is greater than or equal to two, the sidewalk board 10 can be laid in a straight line. The two ends of the connector can be provided with receiving holes (not shown) corresponding to the hanging pins 125. When the connector is inserted into the counterbore 123, the hanging pins 125 are inserted into the receiving holes of the connector, so that the connectors and the hanging pins 125, A composite nested structure is formed between the countersunk holes 123, which restricts the movement of the connecting piece in the axial direction, which can further enhance the guiding effect.
