Description

TECHNICAL FIELD

[0001] The utility model relates to road construction technical field, concretely relates to simple curb expansion joint device technical field. BACKGROUND

[0002] At present, in the road construction process, because the thermal expansion and cold contraction need to be considered, therefore the curb is designed as the broken joint form, leads to the poor integrity of the curb, the uneven road surface has the broken joint, is difficult to clean the snow, extremely easily causes the safety accident, and the broken joint is not beautiful. INNOVATION CONTENT

[0003] In view of the above problem, the utility model discloses a simple curb expansion joint device.Related to road construction technical field.Effectively solve the problem that the curb is designed as the broken joint form because of thermal expansion and cold contraction, there is a safety hazard, the method uses expansion joint design, improves the integrity of the curb, reduces the safety hazard.

[0004] The simple curb expansion joint device, characterized by comprising: curb and connecting plate;

[0005] The two sides of the curb and the connecting plate are connected in the mortise and tenon structure;

[0006] The connecting plate is embedded in the groove range of the curb as a whole.

[0007] Further, the height of the connecting plate is 1-5cm.

[0008] Further, the groove range of the curb includes groove range edge and groove depth;The groove range edge is greater than the outer edge of the connecting plate by 2-5mm;The groove depth is 1-5cm.

[0009] Further, after the connecting plate is embedded in the groove range of the curb, the connecting plate is flush with the curb.

[0010] Further, the shape of the two sides of the connecting plate includes convex polygon and circle.

[0011] The utility model has the advantages of:

[0012] 1, the utility model changes the broken joint form of traditional curb, uses expansion joint design, makes the curb between through expansion joint connection, improves the integrity of the curb, reduces the phenomenon of broken joint of road surface, reduces the cleaning difficulty, reduces the safety hazard of pedestrian.

[0013] 2, the device of the utility model is low in cost, strong in applicability, and various and beautiful in appearance form. DRAWINGS

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1

[0019] like Figures 1-2 As shown, this embodiment provides a simple curbstone expansion joint device, characterized in that it includes a curbstone 1 and a connecting plate 2; the two sides of the curbstone 1 and the connecting plate 2 are connected by a mortise and tenon structure; the connecting plate 2 is embedded entirely within the groove range of the curbstone 1.

[0020] The height of the connecting plate 2 is 1-5cm. The materials of the connecting plate include: the same material as the curbstone, metal and other hard materials. The color and style of the connecting plate can be appropriately adjusted according to the background of the road to match the surrounding environment.

[0021] The grooved area of ​​the curbstone 1 includes the edge of the groove and the groove depth. To ensure that the connection is not damaged by stress during thermal expansion and contraction and to ensure the connection effect, the edge of the groove is 2-5mm larger than the outer edge of the connecting plate 2 (this can be adjusted appropriately according to the temperature difference at the construction site). The groove depth is 1-5cm. This part of the groove work can be done in advance in the factory before the curbstone leaves the factory, or it can be grooved on site.

[0022] After the connecting plate 2 is embedded within the groove of the curbstone 1, the connecting plate 2 is flush with the curbstone 1.

[0023] like Figure 1 As shown, the shapes of both sides of the connecting plate 2 are convex polygons.

[0024] Example 2

[0025] This embodiment provides a simple curbstone expansion joint device, characterized in that, as Figure 3As shown, the shapes of the two sides of the connecting plate 2 are circular; other aspects are the same as those of the embodiment of embodiment 1.
