[0002] The purpose of construction site hoardings is to effectively separate the construction site from its surrounding environment in order to ensure construction safety and protect construction materials and equipment.

[0003] Traditional construction site fencing is typically fixed using scaffolding erected on the ground to form a support structure, with the fencing panels then secured to the scaffolding with wire. This method requires both fixing the scaffolding and securing the fencing panels with wire, making installation time-consuming and labor-intensive, and the wire used poses a safety hazard of scratching pedestrians. To address this, existing technologies have created a triangular support structure for construction site fencing, such as patent CN211691816U, entitled "A Construction Site Fencing". This patent features a U-shaped base at the bottom of the triangular support and I-shaped fasteners at the top, using the U-shaped base and I-shaped fasteners to secure the fencing panels, offering advantages in ease of installation and disassembly. However, this construction site fencing structure still has the following problems: 1. The diagonal supports of the triangular support frame occupy space, potentially causing accidents such as equipment or personnel bumping into each other near the fencing; 2. The overall simplicity and aesthetics of the triangular support frame are low.

[0004] Therefore, there is an urgent need to propose a new type of enclosure structure. Utility Model Content

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model. Specific Implementation Example 1:

[0037] This implementation example Figures 1-5 , Figures 8-10 As shown, a fixed fencing includes a base 1, uprights 2, and an upper fixing device 3. The base 1 has upright insertion holes 4 and retaining grooves 5. The uprights 2 are one of round tubes, square tubes, rectangular tubes, or channel steel. The upper fixing device 3 is installed at the upper end of the uprights 2, and the lower end of the uprights 2 is inserted into the upright insertion holes 4. The lower end of the fencing piece 0 is inserted into the retaining groove 5, and the upper end of the fencing piece 0 is positioned by the upper fixing device 3. In use, the base 1 is transported and hoisted to the location where fencing is needed. Then, the bottom of the fencing piece 0 is inserted into the retaining groove 5 of the base, and the upper part of the fencing piece 0 is fixed by the upper fixing device 3, thus assembling the fencing. Specific Implementation Example 2:

[0039] This implementation example Figure 1 and Figure 2 As shown, the side of the base 1 is also machined with a positioning threaded hole 6, which is connected to the column insertion hole 4. By screwing a "bolt set screw" into the positioning threaded hole 6, the column 2 is fixed on the base 1, which improves the installation stability of the column 2 on the base 1 and prevents the fence panel 0 from becoming unstable and falling after installation. Specific Implementation Example 3:

[0041] This implementation example Figure 1 and Figure 2 As shown, the base 1 is a water-filled barrier, a barricade, or a concrete base.

[0042] Water-filled barriers are plastic shell obstacles used to divide road surfaces or form barriers. They are typically structured with a smaller top and a larger bottom, with holes at the top for filling with water to increase their weight.

[0043] A chevaux-de-frise is a movable obstacle made of wood or iron that cannot be filled with water.

[0044] The concrete base is mainly constructed of reinforced concrete. It features column insertion holes 4, retaining grooves 5, and positioning threaded holes 6. The concrete base is designed to be narrower at the top and wider at the bottom for greater stability and to prevent tipping, as it is fixed to the ground by its own weight; the sides are approximately trapezoidal, and the front is approximately rectangular.

[0045] When the base 1 is a water barrier or a barricade, it is made into a water barrier with a structure of "barrier groove 5, column insertion hole 4 and threaded hole 6". In this way, the assembly of the enclosure piece 0 can be achieved through the structural arrangement of Embodiment 1 and Embodiment 2. Specific Implementation Example 4:

[0047] This implementation example Figure 3 As shown, a fixing baffle 7 is welded to the lower middle part of the column 2. When the lower part of the column 2 is inserted into the column insertion hole 4 of the base 1, the fixing baffle 7 is locked onto the base 1. The structural design of the fixing baffle 7 facilitates the positioning of the column 2 on the base 1. On the other hand, because the fixing baffle 7 is set, the bottom surface of the column 2 is not completely in contact with the bottom surface of the column insertion hole 4, avoiding the column from getting stuck after contact. This allows the direction of rotation of the column to be adjusted so as to install the enclosure plate 0 and the upper fixing device 3. Specific Implementation Example 5:

[0049] This implementation example Figure 1 , Figure 3 and Figure 4 As shown, the upper end of the column 2 is machined with a waist-shaped hole 8, and the upper fixing device 3 is installed in the waist-shaped hole 8.

[0050] The upper fixing device 3 includes a screw 31 and an angle steel 32. The screw 31 and the angle steel 32 are fixedly installed. In specific implementation, the screw 31 is welded to the upper middle position of the angle steel 32. The upper fixing device 3 is installed on the upper end of the column 2 through the screw 31. Specifically, the screw 31 of the upper fixing device 3 is inserted into the oblong hole 8 of the column 2, the upper part of the enclosure piece 0 is placed in the groove formed by the angle steel 32 and the column 2, and the angle steel 32 is pressed down (e.g., ...). Figure 8 (As shown), and then tighten the bolts onto the screw 31 to secure the upper baffle 0 to the column 2. Specific Implementation Example Six:

[0052] This implementation example Figure 1 , Figure 3 and Figure 5 As shown, the difference between this embodiment and specific embodiment five lies in the structure of the upper fixing device 3. In specific embodiment five, the enclosure piece 0 is fixed via a groove formed by the angle steel 32 and the column 1. In this embodiment, the angle steel 32 is replaced with a channel steel 33. Specifically, the upper fixing device 3 includes a screw 31 and a channel steel 33, which are fixedly installed together. The upper fixing device 3 is installed in the oblong hole 8 of the column 2 via the screw 31. In use, the upper part of the enclosure piece 0 is simply placed inside the channel steel 33, the channel steel 33 is pressed down, and then bolts are tightened onto the screw 31 to secure the upper enclosure piece 0 tightly to the column 2. Specific Implementation Example 7:

[0054] This implementation example Figure 6 As shown, the upper fixing device 3 includes a plug 9, a screw 31, and an angle steel 32. The plug 9 has a slotted hole 8 machined on it. The screw 31 and the angle steel 32 are fixedly installed. The upper fixing device 3 is installed in the slotted hole 8 of the plug 9 via the screw 31. In this embodiment, the upper fixing device 3 and the column 2 are separate installation structures. In use, simply insert the plug 9 into the upper part of the column 2. The advantage of this is that, compared to machining the slotted hole 8 on the column 2, machining the slotted hole 8 separately on the plug 9 allows for separate processing of the column 2 and the plug 9. This is because the column 2 also requires welding a fixing baffle 7. Using this plug type allows for separate processing, that is, simultaneously welding the fixing baffle 7 on the column 2 and machining the slotted hole 8 on the plug 9. In use, the two are simply plugged in and assembled. On the other hand, there is no need to machine the waist-shaped hole 8 on the column 2, which ensures the structural strength of the top of the column 2 and avoids the inability to insert the screw 31 after the top of the column 2 is squeezed and deformed during use or transportation. Specific Implementation Example 8:

[0056] This implementation example Figure 7 As shown, unlike specific embodiment seven, the upper fixing device in this embodiment replaces the angle steel 32 with a channel steel 33. Specifically, the upper fixing device includes a plug 9, a screw 31 and a channel steel 33. The plug 9 has a waist-shaped hole 8. The screw 31 is fixedly installed with the channel steel 33. The upper fixing device 3 is installed in the waist-shaped hole 8 of the plug 9 through the screw 31. Specific Implementation Example Nine:

[0058] This implementation example Figure 2 As shown, the base 1 is provided with hoisting and transportation binding holes 10 so that the base 1 can be transported using a transportation vehicle. Specific Implementation Example 10:

[0060] This implementation example Figure 9 and Figure 10 As shown, two door hinges 12 are respectively provided on the left and right sides of the enclosure panel 0, and adjacent enclosure panels 0 are connected by the two door hinges 12. The two door hinges 20 are the door socket and the door hinge. The function of the door socket is to support the rotation of the door hinge to realize the connection between adjacent enclosure panels 0.

[0061] In the above embodiments, the working principle of a fixed fence is as follows:

[0062] 1. Transport and hoist the base 1 to the location on the ground where the enclosure is needed.

[0063] 2. Insert one end of the column 2 into the column insertion hole 4 of the base 1, so that the fixing baffle 7 of the column 2 is locked onto the base 1. Rotate the column 2 to adjust its direction, and use the bolt set screw to tighten the column 2 through the positioning threaded hole 6 of the base 1, so that the column 2 is fixed on the base 1. Figure 1 As shown.

[0064] 3. Install the fencing panel 0. Place the fencing panel 0 into the "groove 5" of the "base 1", and place the upper part into the channel steel (angle steel) of the "upper fixing device 3". By pressing down, tighten the nut to secure the fencing panel 0 tightly to the column. Figure 9 As shown.

[0065] 4. After the next fence panel 0 is connected to the previous fence panel 0 via the double-door hinge 12, repeat the above steps. After installation, as shown... Figure 10 As shown.

[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
