Road isolation guardrail

Abstract

A road isolation guardrail relates to the technical field of road ancillary facilities and comprises a base, a guardrail body vertically mounted on the base and an anchoring part used for fixing the base to a road surface, and further comprises a correcting part used for adjusting the inclination angle of the base so that the guardrail body can be vertically placed. And the base sleeve sleeves the outer side of the base, and the bottom end of the base sleeve is always in contact with the road surface. The guardrail can be kept vertical on a road surface with an inclination angle by correcting the inclination angle of the base, so that the structural design not only improves the aesthetic property and the mounting stability of the isolation guardrail, but also avoids the problem that the inclination of the guardrail occupies the space of a lane, ensures the effective usable area of the road, and improves the safety of the road. And driving is safer. By using the base sleeve, the gap between the base and the road surface can be shielded after the inclination angle of the base is corrected, so that the overall appearance of the isolation guardrail is neater, and the problem that road surface garbage is flushed into the gap between the base and the road surface by water flow to be blocked in the water sprinkling operation process can be avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of road auxiliary facilities, in particular to a road isolation guardrail. Background Art

[0002] Most of the middle parts of urban roads are provided with isolation guardrails, and the guardrails are fixed on the road surface through bases. However, the roads are often designed with a certain inclination angle at the turning points. When the isolation guardrail is installed on the inclined road surface, as Figure 5 shown, the base will incline along with the road surface, which will cause the whole guardrail structure to incline relative to the horizontal plane. This inclination not only affects the stability of the guardrail, but also has poor aesthetics, and at the same time will occupy the road space towards its inclined side. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a new type of road isolation guardrail to improve its installation stability and aesthetics, and avoid the problem of occupying road space due to the inclination of the guardrail.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a road isolation guardrail, including a base, a railing vertically installed on the base, and an anchor for fixing the base to the road surface, and further includes:

[0005] A correction component for adjusting the inclination angle of the base so that the railing is vertically placed;

[0006] A base sleeve, sleeved on the outside of the base and configured such that its bottom end can always be in contact with the road surface.

[0007] Preferably, the correction component includes a wedge-shaped angle pad for inserting between the base and the road surface, the anchor is an anchor bolt, and the anchor bolt is configured to pass through the base and the wedge-shaped angle pad from top to bottom and be anchored to the road surface.

[0008] More preferably, a plurality of anchor holes for the anchor bolt to pass through are provided on the base.

[0009] More preferably, the wedge-shaped angle pad is a rubber pad or a plastic pad.

[0010] Alternatively, the correction component includes a nut fixedly connected to the base and a screw rod threadedly connected to the nut, and one end of the screw rod abuts against the road surface and is configured to rotate the screw rod to adjust the inclination angle of the base.

[0011] Preferably, the base includes a body made of a plastic material, the nut is embedded in the body, and a countersunk hole is vertically opened from top to bottom at a position corresponding to the body and the nut, and the screw rod passes through the countersunk hole and is connected to the nut embedded in the body.

[0012] Compared with the prior art, by correcting the inclination angle of the correction base, the utility model enables the guardrail to remain vertical (perpendicular to the horizontal plane) on a road surface with an inclination angle. Such a structural design not only improves the aesthetic appearance and installation stability of the isolation guardrail, but also avoids the problem of the guardrail inclination occupying the lane space, ensures the effective use area of the road, and makes driving safer. In addition, the use of the base sleeve can cover the gap between the base and the road surface after correcting the inclination angle of the base, making the overall appearance of the isolation guardrail cleaner and avoiding the problem that road garbage is washed into the gap between the base and the road surface and stuck during the sprinkler operation.

[0022] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0023] It should be noted in advance that in the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "attachment", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature can include the first and second features being in direct contact, or can also include the first and second features not being in direct contact but being in contact through other features therebetween. Embodiment

[0024] As Figure 1 and Figure 2 As shown, the road isolation guardrail includes a base 2, a railing 7 vertically installed on the base 2, and an anchor 3 for fixing the base 2 to the road surface. It further includes: a correction component 1 for adjusting the inclination angle of the base 2 to make the railing 7 stand vertically; a base sleeve 4 sleeved on the outside of the base 2 and configured to always be in contact with the road surface at its bottom end during the process of adjusting the inclination angle of the base 2.

[0025] The above-mentioned correction component 1 includes a wedge-shaped angle pad for inserting between the base 2 and the road surface. The anchor 3 is an anchor bolt, which is configured to pass through the base 2 and the wedge-shaped angle pad from top to bottom and be anchored to the road surface. And a plurality of anchor holes 5 for the anchor 3 to pass through are formed in the base 2. The wedge-shaped angle pad is a rubber pad or a plastic pad. The bottom surface and the top surface of the wedge-shaped angle pad are in contact with the road surface and the base 2 respectively. Therefore, wedge-shaped angle pads with various inclined surface angles can be modularly produced and manufactured to adapt to road surfaces with different slope angles. And those skilled in the art should all know that the inclined angles at various places of the sloping road surface are not completely the same, and there are inevitably certain errors at various places and they cannot fit perfectly with the wedge-shaped angle pad, but this does not affect its correction function. Specifically, after the wedge-shaped angle pad is inserted between the isolation guardrail base and the road surface, by adjusting the position of the wedge-shaped angle pad, the base 2 of the isolation guardrail is supported to be close to the horizontal state. At this time, even if there is a gap between the top surface of the wedge-shaped angle pad and the isolation guardrail base, the wedge-shaped angle pad can still provide sufficient supporting force to correct the angle of the guardrail. Moreover, by passing the anchor bolt through the base 2, the wedge-shaped angle pad and fixing it to the road surface, it is ensured that the corrected angle can be maintained. The fastening effect of the anchor bolt ensures that the isolation guardrail can maintain its vertical state even when there is a gap between the top surface of the wedge-shaped angle pad and the base 2.

[0026] Through the above description, the correction structure of this embodiment can still effectively correct the angle of the isolation guardrail without being completely in contact with the base of the isolation guardrail, so that it remains vertically placed on the slope road. Those skilled in the art can understand and implement the correction structure of this application according to the technical solution of this embodiment. Similarly, the base sleeve 4 can also be modularly processed and manufactured, and base sleeves 4 with different inclined surface angles can be selected according to the angles of different slope roads so that the bottom end of the base sleeve 4 can fit the slope road.

[0027] When the road isolation guardrail provided by the above embodiment is installed on the slope road isolation guardrail, first place the base 2 with the base sleeve 4 sleeved on the road surface, then insert the bottom end of the railing 7 in the prefabricated isolation guardrail assembly into the column hole 6 of the base 2, and then slightly lift the base sleeve 4. At this time, the correction component 1, that is, the wedge angle pad, can be inserted between the base 2 and the road surface, and the position of the wedge angle pad is adjusted until the railing reaches the vertical state. During this correction process, in order to improve the efficiency and correction accuracy, the construction personnel can also place a bubble level on the top of the railing and observe the position of the bubble to reach the horizontal state to verify that the railing is vertically placed. After adjustment, the base sleeve 4 can be lowered, and then the anchor bolts are sequentially passed through the anchor holes 5 on the base 2, the wedge angle pad and anchored into the road surface. At this time, the correction work is completed. It should be noted here that the number of anchor holes 5 is at least two and is arranged at a certain distance (as Figure 3 shown). By passing two anchor bolts through the corresponding anchor holes 5 and connecting the wedge angle pad and the road surface, sufficient stability can be ensured to prevent the base 2 from shifting. Embodiment

[0028] As Figure 4 shown, the difference between this embodiment and Embodiment 1 lies in the different structure of the correction component 1. Specifically, the correction component 1 of this embodiment includes a nut 8 fixedly connected to the base 2 and a screw rod 9 threadedly connected to the nut 8. One end of the screw rod 9 abuts against the road surface and is configured to rotate the screw rod 9 to adjust the inclination angle of the base 2. Specifically, the base 2 includes a body made of a plastic material. The nut 8 is embedded in the body, and a countersunk head hole is vertically opened from top to bottom at a position corresponding to the body and the nut 8. The screw rod 9 passes through the countersunk head hole and is connected to the nut 8 embedded in the body.

[0029] In the specific construction process, first place the base 2 with the base sleeve 4 sleeved thereon onto the road surface, then insert the bottom end of the railing in the prefabricated isolation guardrail assembly into the base 2, and then pass the screw 9 through the countersunk hole in the base 2 and connect it with the nut 8. After the bottom end of the screw 9 abuts against the road surface, continuously rotate the screw 9 so that one side of the base 2 moves relative to the screw 9, thereby gradually changing the angle of the base 2 until the railing reaches the vertical state. Compared with Embodiment 1, although this embodiment is slightly lacking in stability, since no anchor is used to drive into the road surface, the damage to the road surface is reduced and a simpler construction method is provided.

[0030] The utility model adjusts the angle of the road isolation guardrail to the vertical state by using the correction component 1, and the base sleeve 4 is arranged around the guardrail base, enhancing the stability and aesthetics of the overall structure. Ultimately, the road safety is improved, the stability of the isolation guardrail is enhanced, and its maintenance cost is also relatively low. It is applicable to slope roads with various inclination angles and has wide applicability and practicability.

[0031] In order to enable those of ordinary skill in the art to more conveniently understand the improvements of the utility model over the prior art, some drawings and descriptions of the utility model have been simplified, and the above embodiments are the preferred implementation schemes of the utility model. In addition, the utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the utility model.
