Description

Anti-slip cover

The present invention relates to a road structure, and more particularly to a manhole cover for closing an opening in an underground tunnel.

With the development of urban construction, many facilities related to people's lives, such as electrical equipment, telecommunications equipment, drainage systems, water pipes or gas pipes, etc., are buried under the road surface to form an intricate network, and for maintenance. The need is to set up a manhole for maintenance personnel to enter for maintenance at a certain distance, and then use the manhole cover to prevent pedestrians from falling in; or in the open drain, a gutter cover will be provided. Prevent accidents like pedestrians from falling into the accident.

In general, whether the manhole cover or the gutter cover is used for supporting strength, most of them are mainly composed of metal or alloy materials, but the metal alloy materials are rubbed against existing road surfaces (such as asphalt roads, red brick roads, etc.). The coefficient is small, so it is easy to cause the vehicle to slip and the pedestrian to slip when it encounters rain or water accumulation.

Referring to Fig. 1, in order to improve the above problem, Taiwan Patent No. M412188 discloses a gutter cover having a non-slip structure, which is disposed on a civil structure 120 forming an underground tunnel 130 under a road surface 110 and enclosing the underground tunnel 130. The opening includes a gutter cover 2 formed with a plurality of perforations 21, and in particular, a plurality of anti-slip bumps 22 are disposed between the perforations 21, and the spacing between the anti-slip bumps 22 is less than The diameter of the anti-slip bumps 22 is long, that is, the arrangement of the anti-slip bumps 22 is relatively dense to achieve Highly anti-slip effect.

Thereby, when the foot of the pedestrian is stepped on the gutter cover 2, the anti-slip bumps 22 of the arrangement of the protrusions can form a plurality of contact points with the sole of the foot, and increase the frictional force to achieve the anti-slip effect; When the tire of the vehicle rolls over the gutter cover 2, the contact points of the tires are increased by the number of contact points of the anti-slip bumps 22 to increase the grip of the tire to prevent slippage.

However, the problem of the gutter cover 2 of such a patterned anti-slip structure is that the anti-slip bumps 22 cannot protrude too much in order to maintain the smoothness of the road surface, and therefore, in particular, on a road section with a large number of vehicles and a large traffic flow. The anti-slip bumps 22 are quickly smoothed to lose the anti-slip function, and when the anti-slip bumps 22 of the gutter cover 2 are flattened, only the new gutter cover 2 can be replaced. Can't fix it easily.

In addition, there are composite material groove covers that are coated with concrete and other materials in a thin metal casing. However, the composite material groove cover generally has poor bearing capacity and can only be used for parks, sidewalks, etc., only pedestrians or bicycles pass by. In the place, when the covering material is peeled off or damaged, the composite material groove cover cannot be easily repaired and replaced by the whole piece, which does not conform to the trend of environmental protection and repeated utilization.

In addition, there is also a method of applying anti-slip coating on the existing manhole cover or the ditch cover to prevent the vehicle from slipping and pedestrians slipping, but the paint itself cannot be attached to the metal manhole for a long time and firmly. Cover or gutter cover, so there is still the need to constantly check and repaint to maintain the anti-slip function.

As can be seen from the above, the existing manhole cover or the gutter cover is improved in use. There are still problems that still need to be improved. Therefore, how to solve the above problems and shortcomings is the direction for the creators of this creation to study and improve.

Accordingly, it is an object of the present invention to provide a non-slip cap that can have a non-slip function and that can be reused and aesthetically pleasing.

Thus, the anti-slip cover of the present invention is used for closing an opening of a subterranean tunnel formed by a civil structure downward from a road surface, comprising a main cover body and a surrounding wall body connected to the main cover body.

The main cover body includes a bottom surface adjacent to the underground tunnel edge and abutting against the civil structure, and a base surface opposite to the bottom surface.

The surrounding wall body extends upward from the base surface of the main cover body, and includes a top surface, and an inner wall surface extending from the top surface facing the base surface of the main cover body and connecting the base surface, and the inner wall surface is The base surface of the main cover body defines a filling space for filling the paving for paving the road, wherein the inner wall surface and the base surface of the main cover body are at an obtuse angle and the top surface and the road surface are paved Qi Ping.

The effect of the invention is that the friction coefficient can be reduced by filling the filling space defined by the main cover body and the surrounding wall body with a laying material having a large friction coefficient and the same material as the road surface. The anti-slip hole cover formed by the small material is exposed on the road surface area, the anti-slip effect is improved, and the laying material can be refilled in the filling space. Therefore, the anti-slip hole cover of the invention not only has good anti-slip effect but can be reused.

The foregoing and other technical contents, features and effects of the present invention will be described in the following detailed description of the preferred embodiments of the reference drawings. Clear presentation.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 2, a first preferred embodiment of the anti-slip cover of the present invention is used to close an opening of an underground tunnel 330 formed by the civil structure 320 downward from the road surface 310, including a main cover 4, and a connection. The main cover 4 surrounds the wall 5.

Firstly, it is generally stated that the civil structure 320 also forms a fixed base 321 surrounding the opening of the underground tunnel 330, not only for maintaining the opening position of the underground tunnel 330 but also for placing the anti-slip cover of the present invention. And the limit, which is a well-known component in the industry and is not the focus of the present invention, so it will not be described in detail here.

The main cover 4 of the first preferred embodiment includes a bottom surface 41 of the underground tunnel 330 against the fixed base 321 of the civil structure 320, and a base surface 42 opposite to the bottom surface 41.

The surrounding wall body 5 is connected to the main cover body 4 and extends upward from the base surface 42 of the main cover body 4, and includes a top surface 51, and a top surface 51 from the top surface 51 toward the main cover body 4. The base surface 42 extends and connects the inner wall surface 52 of the base surface 42, and the inner wall surface 52 and the base surface 42 of the main cover body 4 together define a filling for filling the paving 340 for paving the road. Space 50.

In particular, the angle between the inner wall surface 52 and the base surface 42 is an obtuse angle, and in the first preferred embodiment, it is illustrated as an arc angle, which is intended to make the surrounding wall body 5 and the main cover The junction of the body 4 has a larger, gentler angle. Of course, as shown in FIG. 3, the inner wall surface 52 and the base surface are also The inclination of 42 is increased to an oblique design, with the important point that the inner wall surface 52 and the base surface 42 are not perpendicular to each other.

Similar to the existing manhole cover and the ditch cover, the main cover 4 and the surrounding wall 5 of the first preferred embodiment of the anti-slip cover of the present invention are also made of metal or alloy for the purpose of supporting strength and durability. The material is constructed, and when the first preferred embodiment is used for an asphalt road such as asphalt-fitted stone and used to close the opening of the underground tunnel 330, the filling space 50 is filled with asphalt and stones. The paving 340 of the same composition as the road and the filling height is flush with the road pavement 310. Of course, when used on a concrete pavement, the paving 340 in the filling space 50 can be replaced by concrete or used in a park. The grass lands can also be filled with the 340 of different materials such as dirt and turf. Therefore, the first preferred embodiment of the anti-slip cover of the present invention is only exposed when the top surface 51 of the surrounding wall 5 is exposed, that is, The anti-slip cover of the metal having a relatively small friction coefficient has only a small portion of the area exposed on the road surface 310, and the remaining area is laid in the filling space 50 and is flush with the road surface 310. ,and The material of the paving material 340 is the same as that of the road, and the friction coefficient thereof is relatively large with respect to the material of the surrounding wall body 5, so that not only the problem of slipping due to wet weather, but also the whole road surface can be made more flat, and Consistent with the appearance of the road, increasing overall aesthetics.

At the same time, by the obtuse angle design between the inner wall surface 52 and the base surface 42, the loaded paving 340 can be more completely filled in the filling space 50, and the conventional right angle state can be improved to cause the dead angle to be laid. The problem that the object 340 is not easy to fill; in addition to this, generally the 340 of the paving at the right angle The structural stress of the surrounding main body 4 and the surrounding wall 5 is relatively large, and it is possible to accumulate a hidden destructive force to the overall structure, resulting in a decrease in the service life of the anti-slip cover, so that the design of the obtuse angle can also be Further reduce the stress of the overall structure and increase the service life.

Further, when the road of the first preferred embodiment using the anti-slip cap of the present invention is to be re-laid, or the paving 340 filled in the filling space 50 is damaged and replaced, the original laying can be After the object 340 is dug up and removed, the new paving 340 is refilled, and the obtuse angle design of the inner wall surface 52 and the base surface 42 also facilitates the removal of the paving 340 in the filling space 50; It is said that the anti-slip cap of the invention can be conveniently repaired, refilled and replaced at any time, completely overturning the structural design of the manhole cover or the gutter cover which has the anti-slip function and cannot easily repair the anti-slip material, and provides a repeatable structure. Anti-slip cover with excellent packing and anti-slip function.

Referring to Figure 4, a second preferred embodiment of the anti-slip cover of the present invention is similar to the first preferred embodiment except that the main cover 4' of the second preferred embodiment further includes at least one communication.

For the sake of illustration, in the second preferred embodiment, a plurality of spaced-apart through holes 43 are illustrated, and a plurality of hole plugs 431 that can closely fit to close the corresponding through holes 43 respectively, but As described above, the number and shape of the through holes are flexible, and are not limited to the plurality of through holes 43 and the plug 431 disclosed in the drawings.

Specifically, one of the through-holes 43' of the second preferred embodiment (in this example, a through-hole located at the center of the filling space 50 is illustrated ) is larger than the other through holes 43 , and the hole plug 431 ′ that cooperates with it is also specially designed such that the top edge of the hole plug 431 ′ is flush with the road surface 310 and is exposed on the road surface 310 , and the hole plug 431 ′′ The top edge area is also larger, so that the required characters and patterns can be engraved on the top edge of the hole plug 431'; for example, the characters and patterns can be different from the underground tunnel maintenance unit or engineering unit. The identification mark, therefore, the affiliation unit does not need to re-create the entire anti-slip hole cover for the exclusive identification mark when the new road project is taken, and only the hole plug 431' having the corresponding identification mark needs to be separately prepared.

In the second preferred embodiment, the bottom surface 41 of the main cover 4' can be ejected from the bottom surface 41 of the main cover 4' through the through holes 43 to make it easier to fill the bottom of the space 50. The remaining paving 340 is removed to facilitate filling of the new paving 340 and reuse.

Referring to FIG. 5, a third preferred embodiment of the anti-slip cover of the present invention is similar to the second preferred embodiment, except that the anti-slip cover further includes a plurality of connecting blocks disposed in the filling space 50. Body 6.

Each of the connecting blocks 6 includes a side surface 61 connected to the surrounding wall body 5, a bottom surface 62 extending from the bottom edge of the side surface 61 and connected to the base surface 42 of the main cover body 4', and a connecting side surface 61. And an inclined surface 63 of the bottom surface 62. The inclined surface 63 of each of the connecting blocks 6 is at an obtuse angle with the base surface 42 of the main cover 4', and both face the center of the filling space 50, and the main cover 4 is supported by the connecting block 6 The connection with the surrounding wall 5 makes the overall structure of the third preferred embodiment more stable.

It should be particularly noted that each of the joint blocks 6 in the third preferred embodiment is in the shape of a triangular block, in addition to strengthening the overall structure, the sloped surface The design also makes the filling and removing effect of the laying 340 better, but it can be easily understood that the inclined surfaces 63 do not have to be smooth as shown in the third preferred embodiment. The most important function is to strengthen the connection between the main cover 4' and the surrounding wall 5, and the embodiment can be designed according to the required design, and should not be in the form of the third preferred embodiment. limit.

Referring to FIG. 6, a fourth preferred embodiment of the anti-slip cover of the present invention is similar to the third preferred embodiment, except that the fourth preferred embodiment further includes a plurality of main cover bodies 4'. The convex surface 7 of the base surface 42 protruding toward the road surface 310, and in the fourth preferred embodiment, each convex body 7 is formed in a truncated column shape and arranged neatly in an array, and in the main A textured concave-convex structure pattern is formed on the base surface 42 of the lid body 4'.

In more detail, the pattern design of the protrusions 7 distributed on the base surface 42 of the main cover 4' can assist the cover 340 to fit more closely with the main cover 4 when it is filled in the filling space 50. 'Combined; and compared to the original flattened base 42 (as in the first to third preferred embodiments described above), the paving 340 would be flat on a smooth ground surface 42 It is generally easier to be pushed and removed by external force, but if the design of the concavo-convex pattern of the convex bodies 7 is as in the fourth preferred embodiment, that is, the fitting 340 is fitted therein, the The adhesion of the paving 340 to the anti-slip cap of the present invention.

In addition, the anti-slip caps commonly used in asphalt roads are used to illustrate that when the paving 340 is a harder steel material such as asphalt or concrete, the mesh-like concave and convex pattern design allows the filling to be filled in the The paving 340 in the filling space 50 has a preferred stress direction, and when the surface is broken by a pneumatic machine, it will be more likely to be cracked, so that the paving 340 is more accommodating. Easy to be removed.
