Description

TECHNICAL FIELD

[0001] The utility model relates to road construction technical field, specifically is an environmental protection type road construction isolation device. BACKGROUND

[0002] With the continuous acceleration of urbanization process, the new construction, reconstruction and maintenance engineering of urban road are increasingly frequent. In the process of road construction, in order to guarantee construction safety, maintain traffic order and improve construction efficiency, effective isolation device needs to be set in the construction area. At present, the widely used road construction isolation device on the market mostly adopts the steel pipe lapping to build the support base body, then connects the isolation board on the support base body, to build the isolation wall to realize the isolation of the construction section. This traditional isolation device can meet the basic isolation demand to some extent, but still has some defects. On the one hand, since the support base body is usually composed of lapped steel pipes, in the actual construction process, the spacing between the steel pipes is usually large due to the influence of construction convenience and cost and other factors. This leads to the deformation or even falling of the isolation board when the isolation board is impacted by external force, especially in the middle area, due to the lack of sufficient support. On the other hand, the traditional isolation board is generally thin, and the strength is limited, so it is difficult to maintain the integrity of the structure when facing a large external force impact. The deformation or falling of the isolation board not only seriously affects the isolation effect of the isolation device on the construction section, may cause vehicles to enter the construction area, and cause safety accidents, but also causes a large amount of material waste and increases the construction cost due to frequent replacement of damaged boards. In addition, the construction interruption caused by the damage of the isolation device also greatly reduces the construction efficiency, prolongs the road maintenance period, and causes greater negative impact on urban traffic. SUMMARY

[0025] The technical scheme of the utility model will be further specifically explained below by specific embodiments and in conjunction with the drawings; it should be understood that the specific embodiments described herein are only used for illustrating and explaining the utility model and are not as any limitation on the utility model; the drawings in the utility model are only used for describing the embodiments, facilitating understanding and use, and are not as any relevant limitation on the utility model.

[0026] It should be noted that the structure, proportion, size, etc. shown in the drawings attached to the present specification are only used to cooperate with the content disclosed in the specification, so that people skilled in the art can understand and read, and are not used to limit the limiting conditions that can be implemented by the utility model. Any modification of structure, change of proportion relationship or adjustment of size, which does not affect the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model.

[0027] As described in the background, the baffle of the existing road construction isolation device is usually thin. The baffle is installed between two columns. Because the distance between the columns is large, the support strength of the middle part of the baffle is not enough, and it is easy to deform or even fall off under the action of external force.

[0028] Based on the above reasons, in order to solve the above problems, please refer to the attached Figure 1 and the attached Figure 2The present invention provides the following technical solution: an environmentally friendly road construction isolation device, comprising several columns 1, which are evenly distributed in a straight line on the ground;

[0029] Support netting 3 is detachably installed between columns 1;

[0030] The baffle 2 is attached to the support net 3 and fixed to the support plate 4 on the outside of the support net 3.

[0031] Please see the appendix Figure 3 -Appendix Figure 5 In this embodiment, the column 1 is a hollow square tube with a head 101 at the top and connection holes 102 for installing the support net 3 evenly opened on the side of the column 1.

[0032] As described above, the head is installed at the top of column 1 to prevent rainwater or water droplets from dust suppression spray from falling inside and causing corrosion, and also to facilitate the wrapping of water pipes for dust suppression around the head.

[0033] Please see the appendix Figure 6 In this embodiment, the connecting hole 102 is a strip-shaped hole that is larger at the top and smaller at the bottom, and a V-shaped plate 103 is provided on the inner wall of the column 1 at the bottom of the connecting hole 102.

[0034] In this embodiment, the support net 3 includes a mesh plate and an outer frame disposed on the outside of the mesh plate. The outer frame has an installation hole that matches the width of the lower part of the connection hole 102. After the head of the bolt is inserted into the upper part of the connection hole 102, it slides down to the lower part and contacts the V-shaped plate 103. The bolt shank passes through the installation hole and the support net 3 is connected to the column 1 through the nut.

[0035] When connecting the support net 3 to the column 1, the traditional method is to set connecting plates on the outside of the column and the outside of the outer frame of the support net respectively. After the connecting plates are joined, they are fixed with bolts and nuts. However, the connecting plates on the outside of the column are easy to fall off during transportation, so the connection cannot be made.

[0036] The technical solution adopted is to set the column as a hollow square tube and open the connecting hole 102 on the square tube. The structure of the connecting hole 102 is a strip hole shape with a larger top and a smaller bottom. At the same time, the mounting hole with the width of the smaller end of the connecting hole is opened on the outer frame of the support net 3. During installation, the bolt head is inserted into the column 1 through the larger hole of the connecting hole 102 in advance, and then moved down into the smaller hole to limit the bolt head. Then the bolt shank is passed through the mounting hole of the support net 3 and fixed with the nut.

[0037] Furthermore, since the bolt head cannot be tightened by using tools after being inserted into the column 1, a V-shaped plate 103 is provided below the connecting hole 102 inside the column 1. By having the bolt head stuck in the V-shaped plate 103, the bolt can be prevented from rotating with the nut to a certain extent, making it easier to tighten and loosen.

[0038] To facilitate rapid installation of the support mesh, this technical solution includes connection holes 102 of equal height on all four sides of the column 1. After setting the bolts to a sufficient length, one support mesh 3 is placed at one end of the column 1, followed by another support mesh 3 at the other end. The bolt shank passes through the mounting holes in the outer frame of the support mesh 3, then through the connection holes 102 in the column 1 and the mounting holes in the outer frame of the other support mesh 3, and is secured with a nut. This effectively improves the installation efficiency of the support mesh and ensures the connection strength between the support mesh and the column.

[0039] Please see the appendix Figure 7 and attached Figure 8 In this embodiment, the outer frame of the support net 3 is a hollow tube, and the support plate 4 is inserted into the end of the outer frame of the support net 3 through the bottom connector 401 and fixed with bolts and nuts.

[0040] Because the existing partitions are relatively thin, they are usually installed on the column 1 using self-tapping screws. Since the threaded holes formed by the self-tapping screws cannot be used later, the connection strength is not sufficient. Therefore, the existing partitions cannot be repeatedly installed on the same column 1, resulting in a low reuse rate of the column.

[0041] Based on this, this technical solution attaches the baffle 2 to the support mesh 3 and sets the connection part as a detachable support plate 4. Self-tapping screws are passed through the baffle 2 and tightened onto the support plate 4 to achieve adhesion with the support mesh 3, thereby improving the strength of the baffle 2. When it needs to be reused, only the support plate 4 needs to be replaced.

[0042] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
