Description

Technical Field

[0001] The utility model relates to the technical field of construction safety, in particular to a guardrail for construction engineering. Background Art

[0002] The main purpose of installing guardrails at construction sites is to protect the safety of workers and passers-by, prevent accidents, and reduce safety risks at construction sites.

[0003] Generally speaking, the height of the guardrails required at the construction site depends on factors such as the construction height, the weight of the construction object, and the height of the workers. For higher construction scenes, higher guardrails are needed to ensure the safety of workers and surrounding personnel. For example, when building high-rise buildings or bridges, workers need to work at higher altitudes. In order to avoid high-altitude falls, guardrails of appropriate height are needed for safety protection.

[0004] However, the height of the existing guardrail cannot be adjusted. When a higher guardrail is needed, a higher guardrail needs to be purchased, which brings inconvenience to the construction workers. The higher guardrail is also not easy to store and transport. In addition, since the higher guardrail has a larger windward surface and a higher center of gravity, it is easy to be installed loosely, which brings certain safety hazards to the construction workers. To this end, we propose a guardrail for construction projects. Utility Model Content

[0024] See also Figure 1 In the figure, mounting plates 9 are fixedly connected at both side edges of the lower front end and the lower rear end of the fence body 1, and mounting holes 10 are penetrated at the upper ends of the four mounting plates 9; specifically, the setting of the mounting plates 9 and the mounting holes 10 facilitates the installation and fixation of the guardrail.

[0025] See also Figure 1 In the figure, a handle 3 is fixedly connected to the middle of the upper end of the fence body 2; specifically, the setting of the handle 3 facilitates the fence body 2 to be taken out from the fence body 1.

[0026] Working principle: Figure 1As shown, the height of the fence body 1 and the fence body 2 2 fixed together by two locking mechanisms is greatly increased compared with the height of the fence body 1. In order to make the installation of the fence body 1 and the fence body 2 2 more stable, first, pull the pull plate 15 downward, the pull plate 15 will drive the plug post 14 to slide downward in the inner wall of the fixed plate 8 (in this process, the spring 16 between the pull plate 15 and the fixed plate 8 will be stretched on the outer wall of the plug post 14), and the plug post 14 will slide downward in the hole groove 19 on the limit plate 7 until the plug post 14 completely leaves the hole groove 19, then the long board 2 6 and the corresponding long board 1 5 can be moved forward, the long board 1 5 will rotate forward on the corresponding connecting plate 4, and then the bolt 17 is rotated outward, the bolt 17 will rotate outward in the corresponding screw hole 20 on the long board 2 6 and the corresponding screw hole 20 on the T-shaped plate 18, and the bolt 17 will also rotate outward in the inner wall of the T-shaped plate 18 on the long board 1 5 until the bolt 17 is completely turned away When the long board 26 is in contact with the ground, the long board 26 can be slid downward, and the long board 26 will slide downward at the front end of the long board 15 (in this process, the T-shaped plate 18 on the long board 26 will slide downward in the T-shaped groove 21 on the long board 15), until the bottom end of the limit plate 7 on the long board 26 is in contact with the ground, the bolt 17 can be inserted into and tightened into one of the screw holes 11 in the group of screw holes 11 on the long board 26, and the bolt 17 will also be inserted into and tightened into one of the screw holes 11 on the T-shaped plate 18. The bolt 17 is inserted into one of the screw holes 11 in the group screw hole 11 and is also inserted and tightened into the inner wall of the T-shaped slot 21, so that the long board 2 6 and the long board 1 5 can be kept fixed again, and then the ground nail is inserted into the hole 19 on the limit plate 7 with the help of a hammer or other tools and penetrates into the ground, so that the long board 2 6 and the long board 1 5 can play a diagonal bracing role for the guardrail. Similarly, the same operation can be followed to make the other long board 2 6 and the long board 1 5 play a diagonal bracing role for the guardrail. Similarly, the two long boards 2 6 and their corresponding long boards 1 5 can be reset (i.e., they are in a stored and fixed state, which is convenient for storage and transportation) by following the opposite operation.

[0027] When it is necessary to store the fence body 2 into the fence body 1, first, turn one of the knob screws 13 outward, the knob screw 13 will rotate outward in the corresponding internal threaded tube 12, and the knob screw 13 will also rotate outward in a screw hole 3 22 located at the bottom on the corresponding fence body 2, until the knob screw 13 completely leaves the screw hole 3 22, and then turn the other knob screw 13 away from its corresponding screw hole 3 22 according to the same operation, and then the fence body 2 2 can be stored in the fence body 1, and then the two knob screws 13 are rotated in reverse order, and the two knob screws 13 will both rotate inward in the corresponding internal threaded tubes 12 at each location, and the two knob screws 13 will also be inserted and tightened in the screw holes 3 22 located at the top on the corresponding fence body 2, then the fence body 2 2 stored in the fence body 1 can be fixed in the fence body 1 to prevent the fence body 2 2 from slipping out of the fence body 1 during subsequent transportation.

[0028] It should be noted that the height of the guardrail is adjustable, which brings convenience to construction workers, and when not in use, the fence body 2 can be stored and fixed in the fence body 1, so as to facilitate storage and transportation. At the same time, the two diagonal bracing mechanisms can make the installation of the guardrail more firm and stable, reducing the safety hazards of construction operations.
