Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically to a temporary fence for construction sites. Background Technology

[0002] Traditional fences (or barriers) are mostly rigid, one-piece structures or scattered, single-piece structures. Their inherent volume and shape cause them to occupy a lot of space during non-use periods (such as warehousing and transshipment), greatly increasing storage costs and logistics burdens.

[0003] Furthermore, individual fences lack initial stability during installation, and their upright position can only be achieved by connecting and securing them to adjacent fences. This sequential operation mode, which relies on manual support, results in long assembly times. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a temporary fence for construction sites to solve the problems of large space occupation and long assembly time of the existing fence.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Temporary fencing for construction sites includes: at least one fencing unit;

[0007] At least one of the fence units includes:

[0008] Fence assembly with two fences;

[0009] A connecting component is disposed between the two fences and has two connecting members that are rotatably connected. The two connecting members are respectively connected to the two fences and are used to drive one fence to fold relative to the other fence, forming a folded state and an unfolded state. In the folded state, the two fences are stacked and a cavity is formed between them. In the unfolded state, the two fences are arranged side by side or at an angle.

[0010] The fence is equipped with movable legs on its inner side. Under the action of external force, the legs are used to be housed in the cavity or to support the fence.

[0011] Furthermore, the outrigger includes a first support portion and a second support portion, wherein the first support portion is fixed to the fence, and the second support portion is rotatably connected to the first support portion.

[0012] Furthermore, a locking element is detachably provided at the connection between the first support part and the second support part to restrict or release the rotation of the second support part.

[0013] Furthermore, the fence and the second support are respectively provided with a first positioning block and a second positioning block. In the folded state, the first positioning block and the second positioning block are in contact and locked by the second locking member.

[0014] Furthermore, the side of the fence is provided with a through hole, and the second locking member can be optionally disposed in the through hole.

[0015] Furthermore, the support leg also includes a diagonal brace, which is inclined and its two ends are rotatably connected to the first support portion and the second support portion, respectively.

[0016] Furthermore, the diagonal brace has a telescopic structure.

[0017] Furthermore, the fence assembly also includes a mounting base, wherein at least one mounting rod extends upward from the mounting base and the mounting rod can be inserted into the fence.

[0018] Furthermore, the mounting base is provided with a counterweight.

[0019] Compared with the prior art, the present invention has the following advantages: When the fence unit is folded, it can form a cavity by relying on the two fences, which not only reduces its overall volume for easy storage and transportation, but also allows the legs to be stored inside, preventing parts from being lost or damaged; at the same time, the legs allow each fence to stand independently and stably immediately after unfolding, without the need for additional manual support, shortening the assembly time and improving deployment efficiency.

[0025] The present invention will be further described in detail below through specific embodiments:

[0026] In the embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the temporary fence for the construction site includes: at least one fence unit; at least one fence unit includes: a fence assembly and a connecting assembly; the fence assembly has two fences 1; the connecting assembly is disposed between the two fences 1 and has two rotatably connected connectors 2, the two connectors 2 being respectively connected to the two fences 1, for driving one fence 1 to fold relative to the other fence 1, forming a folded state and an unfolded state. In the folded state, the two fences 1 are stacked, and a cavity is formed between them. In the unfolded state, the two fences 1 are arranged side by side or at an angle; wherein, the inner side 102 of each fence 1 is movably provided with a support leg 3, which is used to be housed in the cavity or to support the fence 1 under the action of external force.

[0027] Specifically, in this embodiment of the invention, two fences 1 are rotatably connected by a connecting component, allowing one fence 1 to rotate relative to the other, thus enabling a single fence unit to be in a folded or unfolded state. Compared to a single-piece structure, this reduces the overall volume for easier storage and transportation. Furthermore, when the fence unit is in the folded state, the two fences 1 are stacked, creating a cavity between them, which can be used as a storage area. Conversely, when the fence unit is in the unfolded state, the rotation of the connecting component allows the two fences 1 to be arranged side-by-side or at an angle, adapting to corners and special terrain on the construction site, offering greater flexibility. The connecting component can be a hinge or a lock, allowing the fence unit in the folded state to rely on its own weight to prevent automatic unfolding; alternatively, corresponding rings can be provided at the fence 1 for binding with ropes.

[0028] In this embodiment of the invention, the fence 1 has an inner side 102 facing the construction area and an outer side 101 facing the non-construction area. The support legs 3 are positioned on the inner side 102 of the fence 1. This maintains the neatness and aesthetics of the outer side 101 and prevents obstruction of the road or tripping of pedestrians. Furthermore, the movable support legs 3 can be retracted into the cavity under external force, preventing the loss or damage of parts during frequent disassembly and transportation, ensuring the integrity of each fence unit. Alternatively, the support legs 3 can be supported on the ground, providing support for the fence 1, increasing overall stability and wind resistance. In the initial installation phase, a single fence 1 can stand stably independently on its own after unfolding, without relying on the support of adjacent structures, making operation simpler and faster. Of course, multiple support legs 3 can be used to further enhance the stability of the fence 1.

[0029] This embodiment combines a foldable fence unit with integrated support legs 3. During storage and transportation, the fence 1 can be folded into a compact form, reducing its space occupation and lowering logistics and warehousing costs. During installation, the support legs 3 enable the fence 1 to stand independently and stably without relying on manual support or adjacent units, improving installation efficiency and shortening operation time. Furthermore, it enhances the stability and durability of the fence 1, prevents the loss of parts, and improves the portability and reliability of the temporary fence 1.

[0030] like Figure 2 , Figure 3 As shown, in one embodiment, the support leg 3 includes a first support portion 301 and a second support portion 302. The first support portion 301 is fixed to the fence 1, and the second support portion 302 is rotatably connected to the first support portion 301. Specifically, in order to store the support leg 3 in the cavity and utilize the limited space to store the support leg 3, thereby reducing the footprint of the fence 1 after folding, this embodiment defines the support leg 3 as having a rotatably connected first support portion 301 and second support portion 302. The first support portion 301 has an H-shaped structure and is fixed to the lower part of the inner side 102 of the fence 1, close to the ground. The second support portion 302 rotates relative to the first support portion 301 to form a stacked arrangement with it, which facilitates storage, or the two are perpendicular to each other, which facilitates support of the fence 1.

[0031] like Figure 3 As shown, in one embodiment, a locking element 4 is detachably provided at the connection between the first support portion 301 and the second support portion 302 to restrict or release the rotation of the second support portion 302. Specifically, in order to keep the second support portion 302 at a corresponding rotation angle, this embodiment provides a locking element 4 at the connection between the first support portion 301 and the second support portion 302. This locking element can be a self-locking hinge. When the second support portion 302 rotates to a position perpendicular to the first support portion 301, the self-locking hinge forms a self-lock, which restricts the rotation of the second support portion 302 without external force. Conversely, pressing the self-locking hinge to unlock it allows the second support portion 302 to rotate relative to the first support portion 301 and be stored in the cavity. Of course, to prevent the self-locking hinge from being accidentally activated, a corresponding counterweight (such as a sandbag) can be provided on the second support portion 302 to further restrict the rotation of the second support portion 302, thereby improving the stability of the fence 1.

[0032] like Figure 3As shown, in one embodiment, the fence 1 and the second support 302 are respectively provided with a first positioning block 5 and a second positioning block 6. In the folded state, the first positioning block 5 and the second positioning block 6 are in contact and locked by the second locking member 7. Specifically, when the support leg 3 is completely retracted into the cavity, in order to prevent the support leg 3 from shaking in the cavity, this embodiment provides a first positioning block 5 and a second positioning block 6 on the inner side 102 of the fence 1 and the second support 302 respectively. When the second support 302 rotates to be close to the inner side 102 of the fence 1, the first positioning block 5 and the second positioning block 6 are in contact. At this time, the second locking member 7 connects the first positioning block 5 and the second positioning block 6, so that the second support 302 can be detachably fixed to the inner side 102 of the fence 1. Then, folding the fence 1 can hide the support leg 3 in the cavity. Of course, the above positioning blocks can also be set in multiple sets to improve the connection stability of the second support 302. Figure 3 As shown, in this embodiment, the locking component 2 7 uses a matching bolt and nut.

[0033] Preferably, such as Figure 2 As shown, the side of the fence 1 is provided with a through hole 8, and the second locking member 7 can be optionally disposed in the through hole 8. When multiple fence units are required, adjacent fence units are spliced ​​together to improve overall stability. In this embodiment, a through hole 8 is provided on the side of the fence 1, through which the bolts that have been removed can pass and be locked by their nuts. This saves on components and also allows the components locking the second support 302 to be transferred to lock the two fence units, preventing component loss. Of course, the number of the second locking member 7 and the through hole 8 can be increased or decreased adaptively, and is not limited here.

[0034] like Figure 2 , Figure 3 As shown, in one embodiment, the support leg 3 further includes a diagonal brace 9, which is inclined and its two ends are rotatably connected to the first support portion 301 and the second support portion 302, respectively. Specifically, to improve the stability of the support leg 3, this embodiment provides a diagonal brace 9 between the first support portion 301 and the second support portion 302, with its two ends rotatably connected to the first support portion 301 and the second support portion 302, respectively; thus, under the action of the diagonal brace 9, the support leg 3 can form a stable triangular structure. Preferably, the diagonal brace 9 has a telescopic structure that can extend and retract with the rotation of the second support portion 302. Alternatively, as... Figure 3 As shown, the diagonal brace 9 includes a first rod and a second rod that are sequentially connected. One end of the first rod can extend and retract within the second rod, thus forming the telescopic structure.

[0035] like Figure 2 , Figure 3As shown, in one embodiment, the fence assembly further includes a mounting base 10, from which at least one mounting rod 11 extends upward, the mounting rod 11 being insertable into the fence 1. Specifically, to improve the stability of the fence 1, this embodiment also provides a mounting base 10, which is supported on the ground, and its upper surface is integrally formed with a mounting rod 11, which is vertically upward so as to be inserted into the bottom of the fence 1. Preferably, the mounting base 10 is provided with a counterweight, or the mounting base 10 has a large overall weight, which helps to stabilize the fence 1. Of course, multiple mounting rods 11 can also be provided, and they can be inserted into different parts of the fence 1 to improve the stability of the assembled fence 1; or multiple mounting rods 11 can be inserted into the same part of the fence 1 to prevent it from tipping over.
