Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to precast concrete curb stones with aggregate interlocking structures. Background Technology

[0002] As a key component of road engineering, curbstones primarily serve to define road boundaries, guide drainage, protect pavement structures, and ensure the safety of pedestrians and vehicles. Their performance directly affects the stability, durability, and maintenance costs of roads. Precast concrete curbstones, with their advantages of standardized factory production (such as high dimensional accuracy and controllable quality), have become the mainstream choice in modern road construction.

[0003] A search revealed that this utility model relates to a curved precast concrete curbstone, with Chinese patent publication number CN 214245198 U. It solves the technical problems of inconsistent curvature and poor aesthetics in curved curbstones at corners, particularly in existing precast concrete curbstones. The curbstone features a ground surface, a vertical surface, and two cross-sections. It also includes an arc surface, with the ground surface, cross-sections, and vertical surface surrounding the arc surface. A chamfer is provided at the junction of the arc surface and the cross-sections. A chamfer is also provided in the middle of the arc surface, perpendicular to the cross-sections. The boundaries between the arc surface and the vertical surface, and between the arc surface and the ground surface, are both curved. This utility model can be widely used in municipal engineering construction.

[0004] The curb stones in the aforementioned patent still have some shortcomings. Since most existing precast concrete curb stones are integrally formed and lack corresponding interlocking structures, when the curb stones are installed on the edge of the road, it is necessary to fix the connection between each pair of curb stones with mortar. Moreover, the stability between each pair of curb stones after fixing is generally poor, and the resistance to deformation is relatively weak. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a precast concrete curbstone with an aggregate interlocking structure. This solves the problem that most existing precast concrete curbstones are integrally formed and lack corresponding interlocking structures. Consequently, when the curbstone is installed on the edge of the road, it is necessary to fix the connection between each pair of curbstones with mortar. Moreover, the stability between each pair of curbstones after fixing is generally poor, and the resistance to deformation is weak.

[0006] This utility model provides the following technical solution: a precast concrete curbstone with an aggregate interlocking structure, comprising two connecting bases, each of which is provided with a curbstone on its top, and two insert blocks are vertically arranged on both sides of the top of the connecting base.

[0007] A limiting block is vertically arranged in the middle of the side of the connecting base. Two insertion holes are symmetrically opened on the side of the curbstone. A limiting groove is opened in the middle of the bottom end of the side of the curbstone. Two connecting slots are symmetrically opened on both sides of the top of the curbstone. A fastening slot is opened at the bottom of each connecting slot. A fastening block is provided between the two curbstones. Two insertion channels are symmetrically opened on the fastening block. The ends of the fastening blocks are inserted into the connecting slots.

[0008] Preferred technical solution 1: Each of the insertion channels is equipped with an insertion post, and the bottom end of each insertion post penetrates the insertion channel and is inserted into the fastening slot.

[0009] Preferred technical solution 2: The side of the curbstone is curved in an arc shape.

[0010] Preferred technical solution 3: The top of the plug block is inclined.

[0011] This solution allows the connector block to pass through the connector hole more smoothly.

[0012] Preferred technical solution four: The inner diameter of the insertion channel is the same as the inner diameter of the fastening slot.

[0013] This design allows the plug-in post to be inserted through the plug-in channel into the fastening slot, connecting the two curb stones.

[0014] Preferred technical solution five: The diameter of the insertion post is the same as the inner diameter of the insertion channel.

[0015] This solution allows for smoother insertion of the plug-in column into the plug-in channel.

[0016] Compared with the prior art, this utility model provides a precast concrete curbstone with an aggregate interlocking structure, which has the following advantages: This utility model provides a curbstone on the top of the connecting base, and the connecting base and the curbstone are connected by a plug-in block inserted into the plug-in hole and a limiting block inserted into the limiting groove. Between every two curbstones, a fastening plug is inserted into the fastening slot. By inserting a plug-in post into the plug-in channel, the bottom end of the plug-in post is inserted into the fastening slot, thereby strengthening the connection stability between each curbstone, improving its deformation resistance, and eliminating the need for additional mortar pouring. The connection between each curbstone is more secure. Attached Figure Description

[0022] Please see Figure 1-4 ,

[0023] Example 1: A precast concrete curb with an aggregate interlocking structure includes two connecting bases 1, each with a curb 2 on its top. Insertion blocks 3 are vertically arranged on both sides of the top of the connecting base 1, and a limiting block 4 is vertically arranged in the middle of the side of the connecting base 1. Two insertion holes 5 are symmetrically opened on the side of the curb 2, and a limiting groove 6 is opened in the middle of the bottom end of the side of the curb 2.

[0024] Two symmetrical connecting slots 7 are opened on both sides of the top of the curbstone 2. A fastening slot 8 is opened at the bottom of each connecting slot 7. A fastening block 9 is set between the two curbstones 2. Two insertion channels 10 are symmetrically opened on the fastening block 9. The ends of the fastening block 9 are inserted into the connecting slots 7. An insertion post 11 is inserted into each insertion channel 10. The bottom end of the insertion post 11 passes through the insertion channel 10 and is inserted into the fastening slot 8.

[0025] The side of the curbstone 2 is curved.

[0026] Example 2: The difference between this example and Example 1 is that the top of the plug-in block 3 is inclined.

[0027] This allows the plug block 3 to pass through the plug hole 5 more smoothly.

[0028] Example 3: The difference between this example and Example 1 is that the inner diameter of the insertion channel 10 is the same as the inner diameter of the fastening slot 8.

[0029] This allows the insertion post 11 to pass through the insertion channel 10 and be inserted into the fastening slot 8, connecting the two edge stones 2.

[0030] Example 4: The difference between this example and Example 1 is that the diameter of the insertion post 11 is the same as the inner diameter of the insertion channel 10.

[0031] This makes it easier for the plug-in column 11 to be inserted into the plug-in channel 10.

[0032] In this embodiment, since most existing precast concrete curb stones are integrally formed and lack corresponding interlocking structures, when the curb stones are installed on the edge of the road, it is necessary to fix the connection between each pair of curb stones with mortar. Moreover, the stability between each pair of curb stones after fixing is generally poor and the resistance to deformation is poor.

[0033] In summary, in specific implementation, a connecting base 1 is provided at the bottom of the curbstone 2. The bottom of the connecting base 1 can be connected to the roadbed with mortar. The curbstone 2 is penetrated by the plug block 3 through two plug holes 5 opened on the side. The limiting block 4 is inserted into the limiting groove 6, thereby completing the connection between the connecting base 1 and the curbstone 2. Between every two curbstones 2, a fastening plug 9 is inserted into the connecting slot 7.

[0034] By inserting an upper insertion post 11 into the insertion channel 10, the bottom end of the insertion post 11 passes through the insertion channel 10 and is inserted into the fastening slot 8, thereby reconnecting the top ends of the two curb stones 2. This strengthens the connection stability between the curb stones 2, improves their resistance to deformation, and eliminates the need to pour mortar between the two curb stones 2. This allows the curb stones 2 to be quickly removed and replaced even if they are damaged, making them more convenient to use.
