Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to a modular and movable construction fence. Background Technology

[0002] In the field of construction, in order to achieve physical isolation between the construction area and the external environment, prevent dust spread, ensure operational safety and maintain site order, it is usually necessary to use a fence structure to limit the construction space to a specific area. The fence, as the core isolation component, is a key element in the structure.

[0003] However, the construction site enclosure structures currently in widespread use have many problems that urgently need to be solved in terms of design and application, specifically in the following aspects: Firstly, the structural design is simplistic and the installation and dismantling efficiency is low. Existing fencing mostly adopts a simple flat structure, requiring additional brackets to be welded to the sides of the fencing for fixation during installation. This not only demands a high level of expertise in welding operations but also results in a cumbersome and time-consuming installation process. At the same time, the welding or bolting method of fixing makes it difficult to quickly dismantle the fencing. When the construction site changes or the fencing needs to be moved and reused, the dismantling process consumes a lot of manpower and time, seriously affecting construction efficiency and the convenience of the fencing's reusability.

[0004] Secondly, the modular adaptability is insufficient, and the applicability to irregular sites is poor. Existing fencing lacks standardized modular combination design, and cannot flexibly adjust the splicing method according to the actual shape of the construction site (such as polygonal, arc-shaped and other irregular sites); moreover, the connection angle between horizontal and vertical components and the overall assembly length of the fencing are fixed and cannot be adjusted. When facing irregular construction areas, it is difficult to achieve a fencing arrangement that closely fits the site boundary, resulting in limited fencing adaptability and inability to meet the isolation needs of diverse construction scenarios.

[0005] In summary, although traditional modular fencing takes the workability (tightness) and interlocking force of horizontal and vertical components as core design factors in its connection structure, it is still limited by connection methods such as welding and bolting. It cannot avoid problems such as cumbersome installation, difficult disassembly, large protective gaps, and poor adaptability to irregular sites. It is difficult to meet the requirements of modern construction for fencing structures in terms of efficiency, sealing and flexibility, and urgently needs technical improvement and optimization.

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0025] Please see Figure 1 and combined Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a modular and movable construction enclosure, which includes multiple columns 1 and multiple nets 2. The columns 1 are spaced apart and connected by the nets 2.

[0026] Specifically, the column 1 of this utility model is made of square steel pipe, and the bottom is equipped with an adjustable base, which can be arranged at intervals of 3 to 5 meters. Connecting plates 3 are symmetrically welded on both sides of the column 1. The connecting plates 3 are made of 5mm thick steel plate and have a size of 200mm×100mm.

[0027] The connecting plate 3 has an elongated connecting hole 31, which is 150mm long and 20mm wide. Multiple semi-circular connecting grooves 32 are evenly spaced along the length of the connecting hole 31. The groove opening diameter is 10mm and the center distance between adjacent connecting grooves 32 is 25mm.

[0028] The connecting plate 3 has an elongated connecting hole 31, and multiple connecting grooves 32 are provided inside the hole. The connecting grooves 32 can be semi-circular or rectangular and are arranged along the length of the connecting hole 31. The connecting hole 31 is also connected to an expansion hole 43, which extends along the width direction.

[0029] The retaining mesh 2 comprises a rectangular steel pipe welded mesh frame 21 and a metal grid 22 filled within it. The mesh frame 21 measures 2000mm × 1200mm. Locking plates 4, made of 4mm thick steel plate, are fixed to both sides of the mesh frame 21. The locking plates 4 have rectangular connecting holes 31, each 30mm × 20mm in size, and arc-shaped grooves 42 with a radius of 8mm are located at the four corners of the connecting holes 31.

[0030] Both ends of the locking hole 41 are connected to expansion holes 43. The expansion holes 43 extend to both sides along the width direction of the locking hole 41, with an extension length of 15mm. The edges of the expansion holes 43 are also provided with arc-shaped grooves 42. For details, please refer to [link to specific structure]. Figure 5 As shown.

[0031] During installation, first align the locking plate 4 with the connecting plate 3, ensuring that the arc-shaped groove 42 on the locking plate 4 corresponds to the connecting groove 32 on the connecting plate 3. Then, insert the U-shaped buckle 5, made of 65Mn spring steel, from one side. The connecting rod 51 of the buckle 5 is 60mm long and 8mm in diameter; the two end clips 52 are 25mm long, and each clip 52 has an inwardly protruding arc-shaped protrusion in the middle, with a protrusion height of 2mm. Applying pressure during installation causes the clips 52 to elastically deform. When the buckle 5 is fully inserted, the clips 52 at both ends respectively engage with the two adjacent diagonally opposite connecting grooves 32. At this point, the arc-shaped protrusion on the clip 52 forms an interference fit with the groove wall of the connecting groove 32, effectively preventing loosening.

[0032] This invention allows for adjustment of the installation height of the baffle 2 within a 150mm range by selecting different positions of the connecting groove 32; and allows for fine-tuning of the horizontal position of the baffle 2 within a 30mm range by selecting the position of the expansion hole 43. The bottom of the connecting plate 3 is bent upward to form a retaining groove 34 with a height of 5mm. This retaining groove 34 can limit the vertical displacement of the locking plate 4 and enhance the connection stability.

[0033] This utility model adopts a modular design, allowing all components to be prefabricated in batches. On-site installation requires only simple assembly. When it is necessary to adjust the position of the fence or dismantle it, the connection can be released simply by pulling out the clip 5 with a special tool, achieving rapid installation and dismantling. This fence system is particularly suitable for construction sites that require frequent layout adjustments, and has high practical and promotional value.

[0034] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
