Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to a safety fence for construction projects. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Construction engineering refers to the process of designing and building buildings by scientifically organizing and managing various resources and rationally utilizing them in construction projects. It includes the entire process from project planning, design, construction to final acceptance.

[0003] During construction, it is necessary to isolate the construction site from all sides. This requires the use of safety fences to help isolate the construction site. By installing fences around the construction site, the safety of the construction site can be protected. In addition, it is also necessary to choose whether to reserve windows in different sections.

[0004] When installing existing safety barriers, if there is a corner, two barriers need to be combined to form a right angle. However, right-angled barriers do not allow pedestrians to easily observe the traffic situation on the other side of the road. Sometimes, multiple barriers need to be combined to form an angled barrier, but this combination method takes up a lot of space. Moreover, existing safety barriers do not have the function of turning, which makes them inconvenient to use in road sections with turning requirements. Utility Model Content

[0018] This utility model provides a safety fence for construction projects. It has the following beneficial effects:

[0019] 1. Rotate the three bases at a certain angle according to the road conditions. During the rotation, the fixed block drives the rotating plate to rotate, and the rotating plate drives the sliding block to slide within the limit frame. At this time, the moving block is not above the sliding block. When the base rotates to a suitable distance, pull the lifting plate and move the moving block laterally. After the moving block moves above the sliding block, release the lifting plate. Under the action of the spring and the limit rod, the lifting plate drives the abutment rod to descend. The abutment rod abuts against the side of the sliding block, thereby locking the rotation angle of the base and frame. This facilitates bending for road conditions that require turning and is convenient to use.

[0020] 2. By pulling the barrier plate and pushing the plate, the movable block moves within the groove inside the horizontal plate. When it is necessary to open the fence to allow pedestrians to observe the road conditions at the corner, the barrier plate is pulled away from the fixed plate, and then the pushing plate and movable block drive the barrier plate to move laterally, so that the gap between the fixed plates is exposed, allowing pedestrians to observe the road conditions through the gap.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a safety fence for construction projects, including three bases 2, which are hinged to adjacent bases 2. A frame 1 is fixedly connected to the upper surface of each of the three bases 2, and the frame 1 is hinged to adjacent frame 1. Several fixing plates 3 are fixedly connected inside the frame 1. A partition assembly 5 is provided on the back of the frame 1, and four locking assemblies 6 are provided on the back of the base 2. Each locking assembly 6 includes a fixing block 601 fixedly connected to the back of the middle base 2, and a rotating... Plate 602, rotating plate 602, is hinged to a sliding block 603 at one end away from the fixed block 601. The outer surface of the sliding block 603 is slidably connected to a limit frame 604. The outer surface of the limit frame 604 is fixedly connected to the outer surface of the adjacent base 2. The upper surface of the limit frame 604 is slidably connected to a moving block 607. The inside of the moving block 607 is fixedly connected to a spring 609. The top of the spring 609 is fixedly connected to a lifting plate 605. The lower surface of the lifting plate 605 is fixedly connected to an abutment rod 606. The outer surface of the abutment rod 606 is fixedly connected to a limit block 610.

[0031] Specifically, the upper surface of the limiting frame 604 is provided with a rectangular groove for the sliding of the abutment rod 606. The inner wall of the rectangular groove is provided with a sub-groove that cooperates with the limiting block 610. The moving block 607 is provided with a circular hole. A limiting rod 608 is inserted into the circular hole. The top end of the limiting rod 608 is fixedly connected to the lower surface of the lifting plate 605. The bottom end of the spring 609 is fixedly connected to the inner wall of the circular hole. The abutment rod 606 abuts against the outer surface of the sliding block 603. There are two lifting plates 605. Two springs 609 are fixedly connected to the lower surface of each lifting plate 605. Two abutment rods 606 are fixedly connected to the lower surface of each lifting plate 605. The distance between the abutment rods 606 connected to the lower surfaces of the two lifting plates 605 is the same as the length of the sliding block 603. A limiting strip 4 is fixedly connected to the outer surface of the base 2 on one side. A groove that cooperates with the limiting strip 4 is provided on the outer surface of the base 2 on the other side.

[0032] Furthermore, the three bases 2 are rotated at a certain angle through the hinge between them. During rotation, the fixed block 601 drives the rotating plate 602 to rotate, and the rotating plate 602 drives the sliding block 603 to slide within the limiting frame 604. At this time, the moving block 607 is not located above the sliding block 603. When the base 2 rotates to a suitable distance, the lifting plate 605 is pulled upward, which drives the abutment rod 606 to move upward, so that the bottom end of the abutment plate rises above the sliding block 603. Then, the moving block 607 is moved laterally. After the moving block 607 is moved above the sliding block 603, the lifting plate 605 is released. Under the action of the spring 609 and the limiting rod 608, the lifting plate 605 drives the abutment rod 606 to descend. The abutment rod 606 abuts against the side of the sliding block 603. The limiting block 610 on the outer surface of the abutment rod 606 cooperates with the sub-groove provided on the upper surface of the limiting frame 604, so that the moving block 607 is fixed. After the moving block 607 is fixed, the abutment rod 606 fixes the sliding block 603, so that the rotating rod cannot rotate.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The partition assembly 5 includes two horizontal plates 504 fixedly connected to the back of the frame 1. Both ends of the horizontal plates 504 are fixedly connected to vertical plates 505. Two movable blocks 503 are slidably connected inside the horizontal plates 504. A push plate 501 is fixedly connected to the end of the movable block 503 away from the horizontal plate 504. Several barrier plates 502 are fixedly connected to the side of the push plate 501 near the fixed plate 3.

[0035] Specifically, the inside of the horizontal plate 504 is provided with a sliding groove, and the inner wall of the sliding groove is provided with two square grooves that cooperate with the movable block 503. The width of the barrier plate 502 is the same as the distance between the two adjacent fixed plates 3.

[0036] Furthermore, by pulling the barrier plate 502 and the push plate 501, the movable block 503 moves within the groove inside the horizontal plate 504. When it is necessary to open the fence to allow passersby to observe the corner road conditions, the barrier plate 502 is pulled away from the fixed plate 3. Then, the push plate 501 and the movable block 503 drive the barrier plate 502 to move laterally, causing the gap between the fixed plates 3 to be exposed. The width of the barrier plate 502, the fixed plate 3, and the gap between two adjacent fixed plates 3 are all the same, so that the barrier plate 502 can fill the gap between two adjacent fixed plates 3. When the movable block 503 is inserted into the square groove, the barrier plate 502 can be inserted precisely between the two fixed plates 3.

[0037] Working principle: When installing safety fences in construction projects, the safety fences are installed according to the road conditions. For road sections where no corners are needed, the installation method of the transmission fence is used. The installation of the fence is completed by the cooperation of the limiting strip 4 and the groove on the outer surface of the base 2. For road sections where corners are needed, the three bases 2 are rotated at a certain angle by the hinge between them. During the rotation, the fixed block 601 drives the rotating plate 602 to rotate, and the rotating plate 602 drives the sliding block 603 to slide within the limiting frame 604. At this time, the moving block 607 is not located within the sliding block 603. Above, when the base 2 rotates to a suitable distance, the lifting plate 605 is pulled upward, causing the abutment rod 606 to move upward, so that the bottom end of the abutment plate rises above the sliding block 603. Then, the moving block 607 is moved horizontally, causing the moving block 607 to move above the sliding block 603. After that, the lifting plate 605 is released. Under the action of the spring 609 and the limiting rod 608, the lifting plate 605 causes the abutment rod 606 to descend. The abutment rod 606 abuts against the side of the sliding block 603. The limiting block 610 on the outer surface of the abutment rod 606 and the sub-block 610 on the upper surface of the limiting frame 604 are respectively set with the limiting block 610. The grooves engage to fix the movable block 607. Once the movable block 607 is fixed, the abutment rod 606 fixes the sliding block 603, preventing the rotating rod from rotating. This locks the rotation angle of the base 2 and the frame 1. Depending on the road section's needs, pulling the barrier plate 502 and the push plate 501 moves the movable block 503 within the groove inside the horizontal plate 504. When it's necessary to open the fence to allow pedestrians to observe the corner road conditions, pulling the barrier plate 502 away from the fixed plate 3, and then using the push plate 501 and the movable block 503 to move the barrier plate 502 laterally, allows... The gap between the fixed plates 3 is left open, making it convenient for passersby to observe the road conditions. For construction sections where it is necessary to protect the construction site and prevent dust from spreading, the barrier plate 502 is pulled to move laterally, causing the movable block 503 to move to the square groove position inside the chute. The barrier plate 502 is then pushed, causing the movable block 503 to be inserted into the square groove, so that the barrier plate 502 seals the gap between two adjacent fixed plates 3, thus achieving the installation of the safety fence. The fence can rotate at a certain angle, and the fixed plates 3 and barrier plates 502 can be adjusted, making it convenient for passersby to observe the road conditions of the perpendicular road sections.
