Description

Technical Field

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

[0002] During the construction process, construction fences serve as important facilities to isolate the construction area from the external environment. Setting up warning signs on their surfaces is a key measure to ensure construction safety. These warning signs can effectively remind passersby to pay attention to construction risks and regulate their behavior, thereby reducing the probability of safety accidents.

[0003] Currently, most warning signs on construction fences are presented by spray painting. This method involves spraying paint directly onto the fence surface with a spray gun to form fixed text, patterns, or symbols. Because the warning signs formed by spray painting are tightly cured on the fence surface, it is difficult to quickly change the content of the signs once the construction scene changes, such as the construction stage changes, the focus of safety warnings is adjusted, or the signs become worn or faded. Moreover, construction units often need to prepare multiple sets of construction fences with different signs pre-painted, which not only increases the procurement, storage, and transportation costs of construction fences, but also causes idle and wasted resources. Therefore, we are introducing a new type of construction fence for building projects. Utility Model Content

[0004] The main purpose of this utility model is to provide a construction fence for building engineering, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A construction fence for building engineering includes a fence panel, an installation plate fixedly installed at the front end of the fence panel, a warning groove opened inside the installation plate, an observation port opened at the front end of the installation plate, an entrance opening at the right end of the installation plate, a closing mechanism jointly provided at the upper right part of the installation plate and inside the entrance opening, and a fixing rod fixedly installed at both the left and right ends of the fence panel, with a counterweight mechanism fixedly installed at the lower end of each of the two fixing rods.

[0006] Preferably, the sealing mechanism includes a top block and a sealing strip. The top block has a sliding groove inside. A pull rod is movably connected to the upper end of the top block. A plug rod is fixedly connected to the lower end of the pull rod. A spring is fixedly connected to the upper end of the plug rod. A slot is opened in the middle of the right end of the sealing strip. A pull block is fixedly connected to the lower right part of the sealing strip.

[0007] Preferably, the lower end of the top block is fixedly connected to the mounting plate, the left end of the sealing strip is movably connected to the lower groove wall of the placement inlet via a movable shaft, and the sliding groove is in communication with the interior of the placement inlet.

[0008] Preferably, the upper part of the insertion rod is slidably connected to the sliding groove, the upper end of the spring is fixedly connected to the upper wall of the sliding groove, and the spring is located outside the pull rod.

[0009] By adopting the above technical solution, the spring force allows the insert rod to be inserted into the slot, enabling the sealing strip to close the entrance and preventing the warning sign from slipping and being lost.

[0010] Preferably, the lower part of the insertion rod is inserted into the slot, and the diameter of the insertion rod is smaller than the diameter of the slot.

[0011] By adopting the above technical solution, the diameter of the insertion rod is smaller than the diameter of the slot, making it easier for the insertion rod to be inserted into the slot.

[0012] Preferably, the counterweight mechanism includes a counterweight base, an anti-slip plate is fixedly installed at the lower end of the counterweight base, a water inlet is fixedly connected to the rear part of the upper end of the counterweight base, a water inlet cover is provided at the upper end of the water inlet, a drain outlet is fixedly connected to the lower part of the front end of the counterweight base, and a drain cover is threadedly connected to the outer surface of the drain outlet.

[0013] Preferably, the upper middle part of the counterweight base is fixedly connected to the fixing rod, and the counterweight base has a hollow structure, with the lower inner wall of the counterweight base having an inclined slope that is lower in the front and higher in the back.

[0014] By adopting the above technical solution, water can be injected into the counterweight to increase its weight and the overall stability of the construction fence. After use, water can be quickly drained to reduce its weight, making the construction fence easier to recycle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By pulling the lever upwards, the lever moves the insert rod upwards, compressing the spring and disengaging the insert rod from the slot. Then, the sealing strip is folded downwards to open the insertion port. The warning sign is placed into the warning slot through the insertion port. The sealing strip is then folded upwards to reset, and the lever is released. Under the reset of the spring, the insert rod is inserted into the slot on the sealing strip, closing the insertion port. This allows for the replacement of warning signs. Construction units only need to stock signs with various content to meet the needs of the entire construction cycle by changing the warning signs, significantly reducing the costs of fencing procurement, storage, and transportation. Furthermore, the linkage system consisting of the lever, insert rod, and spring forms a stable locking structure. Even in the event of strong winds or minor impacts, the sealing strip will not easily open, preventing the warning signs from falling off and being lost, ensuring the long-term stability of the warning function. 2. After the construction fence is transported to the usage site, water can be added to the counterweight by opening the water inlet cover and then closing the cover. This increases the weight of the counterweight, lowers the center of gravity of the fence, and enhances its wind and impact resistance, thereby improving the stability of the construction fence. When construction is completed or the construction fence needs to be moved, the water can be drained from the drain outlet by opening the drain cover. Because the bottom of the counterweight is sloping with a lower front and higher back, the drainage efficiency can be accelerated, and the weight of the counterweight is reduced after drainage, making the construction fence easier to move.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-4 This utility model provides a technical solution: A construction fence for building engineering includes a fence panel 1, an installation plate 2 fixedly installed at the front end of the fence panel 1, a warning groove 3 opened inside the installation plate 2, an observation port 4 opened at the front end of the installation plate 2, an entrance 5 opened at the right end of the installation plate 2, a closing mechanism 6 is provided together at the upper right part of the installation plate 2 and inside the entrance 5, and a fixing rod 7 is fixedly installed at the left and right ends of the fence panel 1, and a counterweight mechanism 8 is fixedly installed at the lower end of the two fixing rods 7.

[0022] In this embodiment, the sealing mechanism 6 includes a top block 61 and a sealing strip 62. The top block 61 has a sliding groove 63 inside. A pull rod 64 is movably connected to the upper end of the top block 61. A plug rod 65 is fixedly connected to the lower end of the pull rod 64. A spring 66 is fixedly connected to the upper end of the plug rod 65. A slot 67 is opened in the middle of the right end of the sealing strip 62. A pull block 68 is fixedly connected to the lower right end of the sealing strip 62. The lower end of the top block 61 is fixedly connected to the mounting plate 2. The left end of the sealing strip 62 is movably connected to the lower groove wall of the inlet 5 through a movable shaft. The sliding groove 63 communicates with the inside of the inlet 5. The upper part of the plug rod 65 is slidably connected to the sliding groove 63. The upper end of the spring 66 is fixedly connected to the upper groove wall of the sliding groove 63, and the spring 66 is located outside the pull rod 64. The lower part of the plug rod 65 is inserted into the slot 67, and the diameter of the plug rod 65 is smaller than the diameter of the slot 67.

[0023] The above method involves pulling the lever 64 upwards, causing the insert rod 65 to move upwards, compressing the spring 66, and disengaging the insert rod 65 from the slot 67. Then, the sealing strip 62 is folded downwards to open the insertion port 5, allowing the warning sign to be placed into the warning slot 3 through the insertion port 5. The sealing strip 62 is then folded upwards to reset, and the lever 64 is released. Under the reset of the spring 66, the insert rod 65 is inserted into the slot 67 on the sealing strip 62, closing the insertion port 5. This allows the warning sign to be replaced.

[0024] In this embodiment, the counterweight mechanism 8 includes a counterweight base 81, an anti-slip plate 82 fixedly installed at the lower end of the counterweight base 81, a water inlet 83 fixedly connected to the rear upper end of the counterweight base 81, a water inlet cover 84 provided at the upper end of the water inlet 83, a drain outlet 85 fixedly connected to the lower front end of the counterweight base 81, a drain cover 86 threadedly connected to the outer surface of the drain outlet 85, a fixed connection between the middle upper end of the counterweight base 81 and the fixing rod 7, and the counterweight base 81 is a hollow structure, with the lower inner wall of the counterweight base 81 having an inclined slope that is lower in the front and higher in the back.

[0025] The above solution involves opening the water inlet cover 84, adding water into the counterweight seat 81 through the water inlet 83, and then closing the water inlet cover 84. This increases the weight of the counterweight seat 81, lowers the center of gravity of the fence, enhances its wind and impact resistance, and improves the stability of the construction fence. When construction is completed or the construction fence needs to be moved, the water can be drained from the drain outlet 85 by opening the drain cover 86. Since the bottom of the counterweight seat 81 has a sloping design that is lower in the front and higher in the back, the drainage efficiency can be accelerated, and the weight of the counterweight seat 81 is reduced after drainage, making the construction fence easier to move.

[0026] It should be noted that this utility model is a construction fence for building engineering. During use, after the construction fence is transported to the location, the operator can open the water inlet cover 84 and inject water into the counterweight base 81 through the water inlet 83. After the water is injected, the water inlet cover 84 is closed. This method increases the weight of the counterweight base 81, lowers the center of gravity of the fence, and thus enhances its wind and impact resistance, improving the stability of the construction fence. When construction is completed or the construction fence needs to be moved, the operator can open the drain cover 86. At this time, the water in the counterweight base 81 will be discharged from the drain outlet 85. Because the bottom of the counterweight base 81 is designed with a slope that is lower in the front and higher in the back, this structure helps to speed up the drainage. After drainage, the weight of the counterweight base 81 is reduced, making the construction fence easier to move. When it is necessary to change the warning sign, the operator pulls the lever 64 upwards. The lever 64 will drive the insert rod 65 to move upwards simultaneously. During this process, the spring 66 is subjected to Upon compression, the insertion rod 65 disengages from the slot 67. Next, the sealing strip 62 is folded downwards to open the insertion port 5. The old warning sign is then removed, and the new warning sign is placed into the warning slot 3 through the insertion port 5. Afterwards, the sealing strip 62 is folded upwards to reset, and the pull rod 64 is released. Under the reset action of the spring 66, the insertion rod 65 inserts into the slot 67 on the sealing strip 62, thus closing the insertion port 5 and completing the replacement of the warning sign. Using this method, construction units only need to stock various signs with different content to meet the needs of the entire construction cycle by changing the warning signs, significantly reducing the procurement, storage, and transportation costs of the fence. Furthermore, the linkage system consisting of the pull rod 64, the insertion rod 65, and the spring 66 forms a stable locking structure. Even in the event of strong winds or minor collisions, the sealing strip 62 will not easily open, preventing the warning sign from falling off or being lost, ensuring the warning function can operate stably and effectively for a long time.
