Civil construction fence

Abstract

This utility model discloses a construction site enclosure for civil engineering, relating to the technical field of civil engineering construction. It includes a base plate with a central rod fixedly connected to its upper surface. The utility model has a reasonable design structure. Through the cooperation of a sliding rod, a locking block, and a limiting plate, by placing the first and second base plates, pulling up the sliding rod releases the limiting plate's restriction on the locking block, rotating the sleeve to a suitable position, and then releasing the sliding rod again, the limiting plate restricts the rotation of the locking block, thereby limiting the sleeve's rotation. Then, placing the third base plate and installing the second baffle fixes the angle between the first and second baffles. This solves the problem that after adjusting the angle between two pieces of enclosure, the lack of a fixed structure causes the angle between the two pieces to change when the enclosure is moved as a whole, requiring readjustment during use and resulting in operational inconvenience.

Description

Technical Field

[0001] This utility model relates to the technical field of civil engineering construction, specifically a civil engineering construction enclosure. Background Technology

[0002] Construction site enclosures are measures taken to isolate a construction site from the external environment, making the construction site a relatively closed space. These include walls built with various masonry materials and protective structures made of various prefabricated panels, which can surround the construction site to facilitate construction.

[0003] However, existing construction site fencing is mostly pieced together. To fit the construction site, two sections of fencing can rotate to adjust their angle. However, without a fixed structure, the angle changes when the entire fencing is moved, requiring readjustment and causing inconvenience. Therefore, we offer civil engineering construction fencing to solve these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a construction site enclosure. Through the cooperation of a sliding rod, a locking block, and a limiting plate, the first and second base plates are placed, the sliding rod is pulled upwards to release the limiting plate's restriction on the locking block, and the sleeve is rotated to a suitable position. Then, the sliding rod is released again, causing the limiting plate to restrict the movement of the locking block, thereby limiting the rotation of the sleeve. The third base plate is then placed, and the second baffle is installed. This fixes the angle between the first and second baffles, solving the problem that after adjusting the angle between two pieces of enclosure, the lack of a fixed structure causes the angle between the two pieces of enclosure to change when the entire enclosure is moved, requiring readjustment during use and resulting in inconvenience.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a construction site enclosure, including a base plate, a central rod fixedly connected to the upper surface of the base plate, a sleeve rotatably connected to the outer surface of the central rod, a vertical plate fixedly connected to the outer surface of the sleeve, a baffle slidably connected to the outer surface of the vertical plate, an installation plate fixedly connected to the outer surface of the sleeve, and a support plate slidably connected to the outer surface of the installation plate;

[0008] A sliding rod slides through the outer surface of the support plate. A locking block is fixedly connected to the bottom end of the sliding rod. A spring is sleeved on the outside of the sliding rod. One end of the spring is fixedly connected to the bottom surface of the support plate, and the other end of the spring is fixedly connected to the upper surface of the locking block. Uniformly distributed limiting plates are fixedly connected to the upper surface of the base plate. The outer surface of the locking block is slidably connected to the outer surface of the limiting plates.

[0009] Furthermore, a slot is provided on the outer surface of the vertical plate, and the outer surface of the baffle is slidably connected to the inner wall of the slot.

[0010] Furthermore, the outer surface of the mounting plate is provided with a mounting groove, and the outer surface of the support plate is slidably connected to the inner wall of the mounting groove.

[0011] Furthermore, a fixing groove is provided on the bottom surface of the card block, and the inner wall of the fixing groove is slidably connected to the outer surface of the limiting plate.

[0012] Furthermore, the outer surface of the mounting plate has a through hole one, and the outer surface of the support plate has a through hole two. An installation rod is slidably connected to the inner wall of the through hole one, and the outer surface of the installation rod is slidably connected to the inner wall of the through hole two.

[0013] Furthermore, the bottom surface of the base plate is fixedly connected to a caster wheel, and the outer surface of the base plate is slidably connected to an insertion rod, which can be inserted into the soil.

[0014] Furthermore, the outer surface of the sleeve has five vertical plates, which are evenly distributed.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this construction site enclosure has the following advantages:

[0017] I. This construction site enclosure utilizes a combination of sliding rods, springs, locking blocks, and limiting plates. By placing the first and second base plates to align the enclosure with the construction site, pulling up the sliding rod releases the limiting plate's restriction on the locking blocks, allowing the sleeve to rotate to the appropriate position. Releasing the sliding rod then allows the limiting plate to restrict the movement of the locking blocks, thus limiting the sleeve's rotation. Placing the third base plate and installing the second enclosure fixes the angle between the first and second enclosures. This solves the problem of inconvenient operation caused by the lack of a fixed structure after adjusting the angle between two enclosure pieces, which would change the angle when the enclosure is moved as a whole and require readjustment.

[0018] II. This civil construction enclosure, through the cooperation between the mounting plate, support plate, through hole one, through hole two and mounting rod, when the spring is fatigued after repeated use, the mounting rod can be removed from the inside of through hole one and through hole two, and then the support plate can be slid out of the mounting groove, so that the limiting mechanism composed of the support plate, spring and sliding rod can be replaced as a whole.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a construction site enclosure, including a base plate 1. The base plate 1 is made of Q235 galvanized steel plate with a rust-proof primer sprayed on the surface, which has anti-corrosion and wear-resistant properties and is suitable for complex outdoor environments. A central rod 2 is fixedly connected to the upper surface of the base plate 1. A sleeve 3 is rotatably connected to the outer surface of the central rod 2. The sleeve 3 is made of high-density polyethylene engineering plastic and has stainless steel guide strips embedded in its inner wall to ensure smooth rotation of the sleeve 3 and maintenance-free operation. A vertical plate 4 is fixedly connected to the outer surface of the sleeve 3. The vertical plate 4 is made of aluminum alloy profile with an anodized surface treatment, which combines lightweight and high strength. A baffle 5 is slidably connected to the outer surface of the vertical plate 4.

[0028] The bottom surface of the base plate 1 is fixedly connected with casters 18, and the outer surface of the base plate 1 is slidably connected with a rod 19. The rod 19 can be inserted into the soil. The casters 18 are polyurethane coated wheels and equipped with brake pads. When the device needs to be moved, only one baffle 5 needs to be moved. The other baffle 5 will move at the same time as the first baffle 5 while maintaining the original angle.

[0029] The outer surface of the vertical plate 4 has a slot 12. The outer surface of the baffle 5 is slidably connected to the inner wall of the slot 12. Plates corresponding to the slot 12 are provided on both sides of the baffle 5, so that it can be locked into the inner wall of the slot 12, facilitating the installation and removal of the baffle 5. There are five vertical plates 4 on the outer surface of a sleeve 3, which are evenly distributed. The slots 12 on the outer surfaces of the vertical plates 4 facilitate the installation of the baffle 5. A mounting plate 6 is fixedly connected to the outer surface of the sleeve 3. A support plate 7 is slidably connected to the outer surface of the mounting plate 6. A mounting groove 13 is provided on the outer surface of the mounting plate 6. The outer surface of the support plate 7 is slidably connected to the inner wall of the mounting groove 13. The mounting groove 13 is concave-convex, and a part of the support plate 7 can be embedded in the interior of the mounting groove 13, thereby restricting the vertical movement of the support plate 7.

[0030] A sliding rod 8 slides through the outer surface of the support plate 7. A locking block 9 is fixedly connected to the bottom end of the sliding rod 8. A spring 10 is sleeved on the outside of the sliding rod 8. When the sliding rod 8 is slid upward, the spring 10 will be compressed. One end of the spring 10 is fixedly connected to the bottom surface of the support plate 7. A through hole 15 is opened on the outer surface of the mounting plate 6, and a through hole 16 is opened on the outer surface of the support plate 7. An installation rod 17 is slidably connected to the inner wall of the through hole 15. The outer surface of the installation rod 17 is slidably connected to the inner wall of the through hole 16. When the spring 10 is fatigued after repeated use, the installation rod 17 can be removed from the inside of the through hole 15 and the through hole 16, and then the support plate 7 can be slid out of the mounting groove 13. The limiting mechanism composed of the support plate 7, the spring 10, and the sliding rod 8 can be replaced as a whole. The support plate 7, the spring 10, and the sliding rod 8 are common structures and can be mass-produced.

[0031] The other end of the spring 10 is fixedly connected to the upper surface of the locking block 9. The upper surface of the base plate 1 is fixedly connected with evenly distributed limiting plates 11. There is a corresponding limiting plate 11 below each vertical plate 4, but the number of limiting plates 11 is greater than the number of vertical plates 4. The bottom surface of the locking block 9 is provided with a fixing groove 14. The inner wall of the fixing groove 14 is slidably connected to the outer surface of the limiting plate 11. The fixing groove 14 is located on the bottom surface of the locking block 9. The limiting plate 11 can be precisely locked in the inner wall of the fixing groove 14, thereby restricting the rotation of the locking block 9. The outer surface of the locking block 9 is slidably connected to the outer surface of the limiting plate 11.

[0032] Working principle: In use, first place the first base plate 1 in a suitable position, then place the second base plate 1 in a suitable position, so that the distance between the slot 12 above the first base plate 1 and the slot 12 above the second base plate 1 is the length of the baffle 5. Pull the sliding rod 8 to release the restriction of the limiting plate 11 on the locking block 9. Rotate the sleeve 3 to align the two pairs of vertical plates 4 on the same straight line. Then, install the two ends of the baffle 5 inside the slots 12 opened in the two vertical plates 4. Then fix the third base plate 1, and at the same time install the second baffle 5 inside the two slots 12. At this time, because the first base plate 1 and the second base plate 1 are in the same position, the distance between the slots 12 above the first base plate 1 and the slot 12 above the second base plate 1 is the length of the baffle 5. Plate 1 and the third base plate 1 are not on the same straight line, so there is a certain angle between the two baffles 5. Then, the slide rod 8 is released, the spring 10 is reset, and the fixing groove 14 on the bottom of the locking block 9 is locked onto the outer surface of the corresponding limiting plate 11, thereby restricting the rotation of the sleeve 3. The sleeve 3 will not rotate relative to the center rod 2, so that the angle between the two baffles 5 will not change. When the spring 10 is fatigued after repeated use, the mounting rod 17 can be removed from the inside of the through hole 15 and the through hole 2 16, and the support plate 7 can be slid out of the mounting groove 13. The limiting mechanism composed of the support plate 7, the spring 10, and the slide rod 8 can be replaced as a whole.
