Description

Technical Field

[0001] This utility model relates to the field of decorative manhole cover installation technology, specifically to a decorative manhole cover installation device. Background Technology

[0002] Currently, decorative manhole covers are commonly used in the paving of municipal sidewalks and park sidewalks because of their good concealment and decorative properties, which makes the overall effect of the paving better. Therefore, they are increasingly widely used in engineering. However, the traditional decorative manhole cover fixing structure is simple in design, and most of them are simply spliced ​​with the manhole cover frame and the base layer. Under the long-term action of pedestrians stepping on them and small vehicles running over them, the frame is prone to loosening, the manhole cover may shift or warp, resulting in insufficient installation stability. In addition, the existing manhole cover lining lacks a dedicated support structure, which can easily lead to structural depressions after long-term use, posing a safety hazard. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a decorative manhole cover installation device.

[0004] A decorative manhole cover installation device includes: a manhole frame and a manhole core. The bottom of the manhole frame is fixedly connected to an inner flange and an outer flange. The inner flange is located inside the manhole frame, and the outer flange is located outside the manhole frame. An embedded part is provided on the outer flange. The manhole core is set inside the manhole frame. A middle plate and a bottom plate are provided on the manhole core. A longitudinal reinforcing rib and a transverse reinforcing rib are fixedly connected between the middle plate and the bottom plate. A paving material is provided above the middle plate, and an adhesive layer is provided between the paving material and the middle plate.

[0005] Furthermore, the longitudinal reinforcing ribs and the transverse reinforcing ribs are positioned perpendicular to each other.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 and Figure 2 A decorative manhole cover installation device is shown, comprising: a manhole frame 1 and a manhole core 2. The bottom of the manhole frame 1 is fixedly connected by welding to an inner flange 10 and an outer flange 11. The inner flange 10 is located inside the manhole frame 1, and the outer flange 11 is located outside the manhole frame 1. An embedded part 9 is fixedly connected by welding to the outer flange 11. The embedded part 9 is hook-shaped. The inner flange 10 and the outer flange 11 are both welded around the bottom of the manhole frame 1. The embedded part 9 is welded to the four corners of the outer flange 11. The manhole core 2 matches the manhole frame 1 and can be tightly installed inside the manhole frame 1. A middle plate 7 and a bottom plate 8 are fixedly connected by welding to the manhole core 2. The middle plate 7 is located above the bottom plate 8. A longitudinal reinforcing rib 3 and a transverse reinforcing rib 12 are fixedly connected between the middle plate 7 and the bottom plate 8 by welding. A paving plate 6 is installed above the middle plate 7. An adhesive is applied between the paving plate 6 and the middle plate 7 to form an adhesive layer 4.

[0023] The aforementioned decorative manhole cover installation device uses an inner flange 10 and an outer flange 11 fixedly connected to the bottom of the manhole frame 1. The manhole core 2 is installed using the inner flange 10, while the outer flange 11 is installed on the bottom of other plates near the manhole. This allows the plates around the manhole to press against the outer flange 11, preventing the manhole core 2 and the paving plate 6 from loosening or shifting. Furthermore, an embedded part 9 is set on the outer flange 11, and the embedded part 9 is fixed by pouring concrete, further fixing the installation position. An adhesive layer 4 is set between the paving plate 6 and the intermediate plate 7, and the paving plate 6 is fixed to the intermediate plate 7 by bonding, effectively preventing the paving plate 6 from loosening and warping, and improving the installation firmness. The longitudinal reinforcing ribs 3 and transverse reinforcing ribs 12 fixedly connected between the intermediate plate 7 and the bottom plate 8 provide special support for the intermediate plate 7, effectively enhancing the structural stability of the intermediate plate 7 and preventing dents.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, the longitudinal reinforcing rib 3 and the transverse reinforcing rib 12 are perpendicular to each other. The longitudinal reinforcing rib 3 and the transverse reinforcing rib 12, which are perpendicular to each other, provide support for the intermediate plate 7 in both the longitudinal and transverse directions, effectively preventing dents after long-term use. Moreover, the longitudinal reinforcing rib 3 and the transverse reinforcing rib 12 are connected by welding, which ensures the stability of the connection.

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, the installation device also includes a corner prism 13, which is set on the intermediate plate 7 and has a lifting hole 5. The corner prism 13 has a right-angled triangle cross section and is a triangular prism structure. The corner prism 13 is fixedly connected to the four corners of the intermediate plate 7 and the well core 2 by welding. Since the cross section of the intermediate plate 7 is rectangular, the right-angled triangle cross section of the corner prism 13 can fit tightly with the four corners of the intermediate plate 7. The lifting hole 5 can be set in the corner prism 13 to facilitate the transfer and handling of the intermediate plate 7 and the well core 2 during the installation process. The cross section of the paving plate 6 is also octagonal. The paving plate 6 is matched with the corner prism 13 and installed into the well core 2. After installation, the paving plate 6 and the corner prism 13 are at the same height and have a flat surface.

[0026] like Figure 1 and Figure 2As shown, in this embodiment, the length of the well core 2 is 90cm and the width of the well core 2 is 90cm. The length and width of the well core 2 can be adjusted according to actual construction needs. Multiple longitudinal reinforcing ribs 3 are evenly distributed between the middle plate 7 and the bottom plate 8, with a spacing of 15cm between the multiple longitudinal reinforcing ribs 3. Multiple transverse reinforcing ribs 12 are evenly distributed between the middle plate 7 and the bottom plate 8, with a spacing of 15cm between the multiple transverse reinforcing ribs 12. By evenly distributing the longitudinal reinforcing ribs 3 and transverse reinforcing ribs 12, uniform force distribution can be ensured, and stress concentration will not occur, thereby effectively ensuring the stability of the structure. The spacing between each longitudinal reinforcing rib 3 and transverse reinforcing rib 12 can be adjusted according to the length and width of the well core 2 to ensure uniform distribution.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the thickness of both the longitudinal reinforcing rib 3 and the transverse reinforcing rib 12 is 8mm; the thickness of the longitudinal reinforcing rib 3 and the transverse reinforcing rib 12 can be adjusted according to the actual situation to ensure the strength required for use.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the inner flange 10 has a width of 5cm and a thickness of 5mm; the outer flange 11 has a width of 10cm and a thickness of 5mm. Since the outer flange 11 is mainly used to press against the bottom of the plate around the well, while the inner flange 10 is mainly used to install the well core 2, the width of the inner flange 10 is smaller than the width of the outer flange 11, ensuring that the device is installed more firmly.

[0029] like Figure 1 and Figure 2 As shown in this embodiment, during installation, the well frame 1 with the pre-embedded part 9 welded on it is first installed around the well and leveled according to the design elevation. Then, concrete is poured to fix the pre-embedded part 9 and the well frame 1 in the base layer. Then, the corner prism 13 and the well core 2 are transferred using the lifting hole 5. The well core 2 is installed on the inner flange 10. Then, the plate around the well is pressed onto the outer flange 11. Adhesive is applied to the mating surface between the paving plate 6 and the intermediate plate 7. Specifically, it can be a special tile adhesive. The application process needs to ensure that the thickness is uniform. Then, an adhesive layer 4 is formed. The paving plate 6 is laid into the intermediate plate 7 for fixing and bonding.

[0030] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
