Technical Field

[0001] This application relates to the technical field of municipal road facilities, and particularly to a safety guardrail for municipal road construction. Background Art

[0002] The protection of municipal roads usually adopts green belts with isolation functions and guardrails to divert vehicles, so as to ensure the normal operation of the road and the safe driving of vehicles.

[0003] Existing guardrails mainly include columns, crossbars and vertical bars. There are two columns which are symmetrically arranged. There are two crossbars which are arranged vertically. The two ends of the crossbar are respectively fixed between the two columns by bolts. There are multiple vertical bars, and the two ends of the vertical bar are welded between the two crossbars or fixed between the two crossbars by bolts.

[0004] However, it is found in the actual application process that:

[0005] 1. For the guardrail in which the crossbar, vertical bar and column are connected by bolts, it is time-consuming and laborious to fix by tightening bolts one by one during installation;

[0006] 2. For the guardrail in which the crossbar and vertical bar are welded, although only the crossbar and column need to be fixed by bolts during installation, but after damage, it can only be replaced as a whole, and the cost is relatively high. Utility Model Content

Specific embodiments

[0042] The following will further describe the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0043] An embodiment of the present application discloses a safety guardrail for municipal road construction. Referring to Figure 1 , the safety guardrail includes a column 1, an upper cross bar 2, a top seat 3, a positioning member 4, a lower cross bar 5 and a vertical bar 6.

[0044] Referring to Figure 1 and Figure 2 , there are two columns 1, and the two columns 1 are symmetrically arranged. A base 11 is installed at the bottom of the column 1. The base 11 is in the shape of a frustum of a pyramid, smaller at the top and larger at the bottom. A vertical through hole is processed on the base 11 for driving expansion bolts to fix it on the ground. The inside of the column 1 is hollow and both ends are open. U-shaped notches 12 are opened on two opposite side walls of the column 1, and the open ends of the U-shaped notches 12 penetrate through the top of the column 1.

[0045] Referring to Figure 2 and Figure 3 , both ends of the upper cross bar 2 are inserted into the two columns 1 from the U-shaped notches 12. To improve the structural stability, a supporting plate 13 for supporting the upper cross bar 2 is fixedly connected inside the column 1, and the upper surface of the supporting plate 13 is flush with the concave surface of the U-shaped notch 12. Positioning holes 21 penetrating through are processed at positions near both ends of the upper cross bar 2, and the positioning holes 21 are opened along the direction perpendicular to the length of the upper cross bar 2. A positioning plate 14 is fixedly connected to the middle position of the upper surface of the supporting plate 13. During installation, the end face of the upper cross bar 2 is abutted against the positioning plate 14. At this time, the positioning holes 21 reach the specified fixed positions.

[0046] The top seat 3 includes a housing 31. The interior of the housing 31 is hollow and one end is open. The cross-section of the housing 31 is rectangular and is sleeved on the top of the vertical column 1. The inner side wall of the housing 31 is fitted with the outer side wall of the vertical column 1. A plug 32 is fixedly connected to the inner top wall of the housing 31. When the housing 31 is sleeved on the vertical column 1, the outer side wall of the plug 32 is fitted with the inner side wall of the vertical column 1. In order to improve the reliability of the base 11 after installation, a rubber sleeve 33 is sleeved on the plug 32, which is mainly used to increase the friction between the plug 32 and the vertical column 1 and play a role in preventing detachment.

[0047] Referring to Figure 3 , a fixing plate 34 is fixedly connected to the free end of the plug 32. Symmetrically fixed on the side of the fixing plate 34 away from the plug 32 are positioning columns 35, which are adapted to the positioning holes 21 and are designed according to the shape of the positioning holes 21. During installation, the top seat 3 is installed on the vertical column 1 by pressing, so that the positioning columns 35 are directly inserted into the positioning holes 21 of two adjacent upper crossbars 2, realizing the fixation of two adjacent upper crossbars 2.

[0048] In order to improve the appearance of the safety guardrail and facilitate the operation of the staff, a connecting column 36 is fixedly connected to the outer top wall of the housing 31, and a sphere 37 is fixedly connected to the end of the connecting column 36 away from the housing 31. During the operation, the sphere 37 can be used as a holding part.

[0049] Referring to Figure 2 , two positioning members 4 are pre-installed on each vertical column 1. The two positioning members 4 are detachably and fixedly connected to the side wall of the vertical column 1 near the bottom. The positioning members 4 and the U-shaped notches 12 correspond one by one, and the corresponding positioning members 4 and U-shaped notches 12 are on the same side wall. The setting of the positioning members 4 is mainly used for installing the lower crossbar 5. More specifically, the positioning member 4 includes a mounting plate 41 and a sleeve 42 fixedly connected to one side of the mounting plate 41. The interior of the sleeve 42 is hollow and one end away from the mounting plate 41 is open. The inner wall shape of the sleeve 42 is designed according to the cross-sectional shape of the lower crossbar 5, and the mounting plate 41 is fixed to the vertical column 1 by bolts. During installation, the two ends of the lower crossbar 5 are respectively inserted into the sleeve 42, and they are adapted to each other.

[0050] Referring to Figure 4 , multiple vertical rods 6 are provided. Limiting blocks 61 are fixedly connected to both ends of each vertical rod 6. Multiple limiting holes are respectively machined on the opposite sides of the upper crossbar 2 and the lower crossbar 5. During installation, the vertical rods 6 are inserted and matched through the limiting blocks 61 and the limiting holes to be fixed between the upper crossbar 2 and the lower crossbar 5.

[0051] The implementation principle of the embodiment of this application is as follows: During installation, the upper crossbar 2, the lower crossbar 5 and the vertical bar 6 are connected as a whole by the insertion fit of the limit block 61 and the limit hole. Then, the column 1 is moved so that the two ends of the lower crossbar 5 are respectively inserted into the sleeves 42 of the positioning member 4, and the upper crossbar 2 is inserted into the two columns 1 and abuts against the positioning plate 14. At this time, the top seat 3 is installed on the column 1 by pressing, so that the positioning column 35 is directly inserted into the positioning holes 21 of two adjacent upper crossbars 2, realizing the assembly of the whole safety guardrail.

[0052] Compared with the guardrails in the prior art, the safety guardrail in this application only requires simple assembly and clamping, without too many bolt fasteners and welding, greatly improving the installation efficiency. At the same time, after the safety guardrail is damaged, only a single component can be replaced, greatly reducing the replacement cost.

[0053] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
