Description

Technical Field

[0001] The utility model belongs to the technical field of construction guardrails, and particularly relates to a guardrail for highway reconstruction construction. Background Technique

[0002] During highway reconstruction construction, the general method is to arrange guardrails in sequence to separate the construction road from the normal lane to remind others that the road is under construction and ensure the normal progress of highway construction. In order to prevent unauthorized removal of the guardrails by irrelevant personnel and entry into the construction area, the prior art discloses a reinforcement device for construction guardrails of construction buildings (publication number CN221609713U). By using the first clamping block, the second clamping block and a plurality of screw rods for fixation, it can effectively fix two adjacent guardrails. However, in this technology, when fixing the guardrails, it is necessary to screw in a plurality of screw rods between the first clamping block and the second clamping block, and the operation is not simple enough. In order to optimize the inconveniences existing in the prior art, we propose a guardrail for highway reconstruction construction. Content of the Utility Model

[0003] The purpose of the utility model is to provide a guardrail for highway reconstruction construction to solve the problems existing in the background technique.

[0004] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A guardrail for highway reconstruction construction includes a plurality of guardrails and a plurality of fixing mechanisms. Vertical rods are arranged vertically on both sides of the guardrails. The bottoms of the vertical rods on both sides are fixedly connected with U-shaped bottom frames that open downward and are arranged longitudinally. Two adjacent vertical rods of two adjacent guardrails are connected through the fixing mechanism;

[0006] The fixing mechanism includes two diagonal connecting strips. The upper ends of the diagonal connecting strips are fixedly provided with longitudinal clamps extending longitudinally towards the vertical rods. The lower ends of the diagonal connecting strips are fixedly provided with vertical clamps extending downward. The longitudinal clamps match the vertical rods, and the vertical clamps match the horizontal sections of the tops of the U-shaped bottom frames.

[0007] Both the longitudinal clamps and the vertical clamps are elastic plastic clamps. The opening size of the longitudinal clamps is slightly smaller than the diameter size of the vertical rods, and the opening size of the vertical clamps is slightly smaller than the diameter size of the horizontal sections of the tops of the U-shaped bottom frames.

[0008] Both of the two diagonal connecting strips are provided with positioning through holes in the middle. The fixing mechanism is further provided with an anti-disengagement component. The anti-disengagement component includes a positioning rod and two positioning nuts. The positioning rod matches the positioning through holes and is provided with threaded sections on both sides. The two positioning nuts are respectively threadedly connected with the threaded sections on both sides.

[0009] Threaded platforms are provided at the bottoms on both sides of the U-shaped chassis, and each of the threaded platforms is threadedly connected with a height-adjusting threaded sleeve.

[0010] Crossbars are further provided on the upper sides of the two vertical bars of the guardrail, hooks are machined on both sides of the crossbar, and the construction sign is jointly hung by the hooks on both sides.

[0011] In the utility model, by providing a U-shaped chassis with an opening facing downward and longitudinally arranged at the bottom of the vertical bars on both sides of the guardrail, the guardrail is more stable in the longitudinal direction and is not prone to tilting; by using the vertical bars and the U-shaped chassis of the guardrail, a fixing mechanism composed of two obliquely connecting bars is designed, and the stable clamping of two adjacent guardrails is completed in a cross-clamping manner, without the need to drive in a large number of fixing parts and screws, and the operation is more convenient.

Detailed Description of the Embodiment

[0019] In order to enable those skilled in the art to better understand the utility model, the technical solutions of the utility model will be further described below in conjunction with the drawings and embodiments.

[0020] Embodiment:

[0021] As Figures 1 to 4A highway reconstruction construction guardrail shown in the figure includes a plurality of guardrails 100 and a plurality of fixing mechanisms. In the figure, two guardrails 100 and one fixing mechanism are taken as examples. Vertical rods 101 are arranged vertically on both sides of the guardrail 100. U-shaped bottom frames 102 with openings facing downwards and arranged longitudinally are fixedly connected to the bottoms of the vertical rods 101 on both sides. By arranging the U-shaped bottom frames 102 with openings facing downwards and arranged longitudinally at the bottoms of the vertical rods 101 on both sides of the guardrail 100, the guardrail 100 is more stable in the longitudinal direction and is not prone to tilting or falling. Two adjacent vertical rods 101 of two adjacent guardrails 100 are connected by a fixing mechanism;

[0022] The fixing mechanism includes two diagonal connecting bars 110. A longitudinal clamp 111 extending longitudinally towards the vertical rod 101 is fixedly arranged at the upper end of the diagonal connecting bar 110. A vertical clamp 112 extending downwards is fixedly arranged at the lower end of the diagonal connecting bar 110. The longitudinal clamp 111 matches the vertical rod 101, and the vertical clamp 112 matches the horizontal section at the top of the U-shaped bottom frame 102.

[0023] When the fixing mechanism is in use, the following operations can be carried out:

[0024] ① Select two adjacent guardrails 100. As Figure 1 shown, first, on the front of the guardrail 100, clamp the longitudinal clamp 111 of one of the diagonal connecting bars 110 with one of the vertical rods 101 of the guardrail 100, and then slide the diagonal connecting bar 110 downwards so that the vertical clamp 112 at the bottom of the diagonal connecting bar 110 clamps the horizontal section at the top of the U-shaped bottom frame 102 of the other guardrail 100, completing the clamping of the first diagonal connecting bar 110;

[0025] ② As Figure 3 shown, use the same operation to complete the clamping of the second diagonal connecting bar 110 from the back of the guardrail 100. It should be noted that the longitudinal clamps 111 of the two diagonal connecting bars 110 need to clamp the two vertical rods 101 respectively, and the vertical clamps 112 need to clamp the horizontal sections at the tops of the two U-shaped bottom frames 102 respectively. In this way, the clamping of the fixing mechanism is completed. At this time, the two diagonal connecting bars 110 are in a cross-clamping state, and the two guardrails 100 will be combined into a whole and can no longer flip, approach, or move away from each other, thus ensuring the stability of the connection between the two guardrails 100.

[0026] By using the above operations, a plurality of guardrails 100 can be connected, thus ensuring the stability of the guardrails 100.

[0027] The fixing mechanism of the present utility model has a simple structure, is convenient for processing and operation, and does not require a large number of screws to be driven in for fixing.

[0028] As a further description of this embodiment, as Figure 2 andFigure 4 As shown, both the longitudinal clip 111 and the vertical clip 112 are elastic plastic clips. The opening size of the longitudinal clip 111 is slightly smaller than the diameter size of the vertical rod 101, and the opening size of the vertical clip 112 is slightly smaller than the diameter size of the horizontal section at the top of the U-shaped chassis 102.

[0029] The opening size of the longitudinal clip 111 is set to be slightly smaller than the diameter size of the vertical rod 101, and the opening size of the vertical clip 112 is set to be slightly smaller than the diameter size of the horizontal section at the top of the U-shaped chassis 102. Elastic plastic clips are used as the longitudinal clip 111 and the vertical clip 112, making it more stable and not easy to loosen when clamping the vertical rod 101 and the horizontal section at the top of the U-shaped chassis 102.

[0030] In order to prevent the two diagonal connecting bars 110 from loosening, on the basis of the above, further improvements are made. The specific improvement content is as Figure 2 and Figure 4 shown. Both of the two diagonal connecting bars 110 are provided with positioning through holes in the middle. The fixing mechanism is also provided with an anti-loosening component. The anti-loosening component includes a positioning rod 113 and two positioning nuts 114. The positioning rod 113 matches the positioning through holes and is provided with threaded sections 115 on both sides. The two positioning nuts 114 are respectively threadedly connected to the threaded sections 115 on both sides.

[0031] After the clamping is completed, by passing the positioning rod 113 through the positioning through holes of the two diagonal connecting bars 110, and then screwing the positioning nuts 114 into the threaded sections 115 on both sides of the positioning rod 113 until the positioning nuts 114 on both sides respectively abut against the two diagonal connecting bars 110, the two diagonal connecting bars 110 can be prevented from loosening and the stability can be improved.

[0032] In order to enable the guardrail to be adjusted in height to adapt to uneven roads, further improvements are made on the basis of the above. The specific improvement content is as Figure 2 shown. Threaded platforms 120 are provided at the bottoms of both sides of the U-shaped chassis 102, and each threaded platform 120 is threadedly connected with a height-adjusting threaded sleeve 121.

[0033] On uneven roads, people can rotate the height-adjusting threaded sleeves 121 to increase or decrease the overall height of the threaded platforms 120 and the height-adjusting threaded sleeves 121, so that the U-shaped chassis 102 will not be suspended and the stability of the U-shaped chassis 102 under support force can be ensured.

[0034] At the same time, further explanations and improvements are also made on the structure of the guardrail, as Figure 1 shown. Crossbars 130 are also provided on the upper sides of the two vertical rods 101 of the guardrail 100. Hooks 131 are processed on both sides of the crossbar 130, and a construction sign 132 is jointly hung by the hooks 131 on both sides.

[0035] By using the cross bar 130 on the upper side of the guardrail 100, the construction sign 132 can be conveniently hung by installing a hook 131 on the cross bar 130, thereby improving the practicability of the guardrail 100.

[0036] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
