Description

Technical Field

[0001] This utility model relates to the field of enclosure structure technology, specifically a modular and combined temporary enclosure structure for civil construction. Background Technology

[0002] During civil construction, temporary fencing serves as a crucial facility for isolating the construction area from the surrounding environment. Its main functions are to ensure construction safety, reduce dust and noise pollution, and maintain site order. Currently, common temporary fencing often employs modular structures such as color steel plates, PVC panels, or metal sheets, which are spliced ​​together to form continuous isolation barriers. To adapt to the flexibility requirements of construction sites, modular fencing is typically designed with a structure that can be quickly disassembled, transported, and reused. The splicing efficiency and sealing performance of its base and panels directly affect the overall practicality of the fencing.

[0003] When assembling existing modular fencing, adjacent panels often rely on simple docking of bases for assembly. Due to processing errors and installation precision limitations, gaps easily appear at the docking points between the panels and the bases. To solve this gap problem, traditional methods require additional sealing procedures after assembly, such as adding sealing strips, applying sealant, or manually installing cover plates. This not only increases construction steps and labor intensity but may also reduce the protective effect due to improper sealing operations. Furthermore, some fencing base docking structures lack stable guiding and positioning mechanisms, making misalignment prone to occur during assembly, affecting the overall structural stability and sealing of the fencing. Therefore, a modular, combined temporary fencing structure for civil construction is needed to solve the problems existing in current technologies. Utility Model Content

[0004] The purpose of this utility model is to provide a modular and combined temporary enclosure structure for civil engineering construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular combined temporary construction enclosure structure, comprising a first baffle and a second baffle. A first base is fixed to the lower end of the first baffle, and a second base is fixed to the lower end of the second baffle. Both the first and second bases have a docking structure inside. The docking structure includes a driven toothed plate. Both driven toothed plates are slidably connected inside the first and second bases. Adjusting gears are rotatably connected in the cavities of both the first and second bases. A driving toothed plate is fixed to the inner sidewall of both the first and second bases. The adjusting gears are meshed between the driven toothed plate and the driving toothed plate. A sealing cover plate is fixed to the upper end of the driven toothed plate.

[0006] Preferably, the first base and the second base have a receiving groove on the side surface near the closure cover plate, and the closure cover plate is slidably disposed in the receiving groove.

[0007] Preferably, a sealing strip is fixed to the inner surface of the sealing cover, and one side of the sealing strip is attached to the wall where the receiving groove is located.

[0008] Preferably, the inner top and bottom walls of the first base and the second base are each fitted with a fixed pivot, and the journal of the adjusting gear is rotatably connected inside the fixed pivot.

[0009] Preferably, the driven gear plate and the driving gear plate are arranged opposite each other on both sides of the adjusting gear.

[0010] Preferably, the inner bottom walls of the first base and the second base are provided with positioning grooves, and the lower end of the driven toothed plate is fixed with a positioning slide.

[0011] Preferably, the positioning carriage is slidably connected in the positioning groove.

[0012] Preferably, the upper surfaces of the first base and the second base are provided with relief grooves, and the sealing cover is slidably connected in the relief grooves.

[0013] Preferably, the second baffle is disposed on one side of the first baffle.

[0014] Preferably, the second base is disposed on one side of the first base, and when the second base is connected to the first base, the second baffle is connected to the first baffle synchronously.

[0015] This utility model provides a modular and combined temporary construction enclosure structure for civil engineering, which has the following advantages compared with the prior art:

[0016] (1) During the splicing process, there is no need to perform a separate sealing operation. By simply pushing the second base to connect with the first base in a straight line, the active toothed plate, the adjusting gear and the driven toothed plate can automatically drive the sealing cover to slide to the front of the baffle joint by means of the linkage structure. This integrates the step-by-step process of "connection + sealing" into a synchronous operation, greatly reducing manpower input and time consumption, and making the combination and installation of the enclosure more convenient and efficient.

[0017] (2) The sealing cover plate is put into place synchronously during the docking process, and the sealing strip on its inner side is attached to the wall where the receiving groove is located, which can effectively seal the docking seam of adjacent baffles. This design reduces the problem of reduced wind resistance, dust prevention and noise reduction performance caused by excessively large joints, improves the protective ability of the fence during construction, and better isolates the construction area from the surrounding environment.

[0018] (3) When the base is docked, the positioning slide at the lower end of the driven tooth plate slides in the positioning slide groove, providing stable guidance for the movement of the driven tooth plate. At the same time, during the docking process between the second base and the first base, the synchronous insertion of the driven tooth plate and the positioning slide achieves preliminary positioning, reducing the misalignment caused by accidental displacement before docking and improving the accuracy and structural stability of docking.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a modular and combined temporary construction site enclosure structure. This modular and combined temporary construction site enclosure structure mainly consists of two parts: a baffle and a base. It achieves rapid assembly and sealing through a precise docking structure 5. The specific structure and working mechanism are as follows:

[0026] The enclosure structure includes a first baffle 3 and a second baffle 4, with the second baffle 4 positioned on one side of the first baffle 3, allowing for synchronous docking. A first base 1 and a second base 2 are fixed to the lower ends of the corresponding baffles, with the second base 2 located on one side of the first base 1. When the two bases dock, the baffles also dock synchronously. This coordinated design of the bases and baffles lays the foundation for the modular assembly of the enclosure. During docking, the driven toothed plate 6 and the positioning slide 8 of the second base 2 are simultaneously inserted into the inner cavity of the first base 1, achieving initial positioning at the initial stage of assembly and reducing misalignment caused by accidental displacement before fastener tightening. The docking structure 5 inside the base is crucial for achieving rapid assembly and sealing. Its core components and connections are as follows: Adjusting gears 7 are rotatably connected to the inner cavities of both the first base 1 and the second base 2. The gear journals achieve stable rotation via a fixed-point rotating seat 13 (embedded in the inner top and bottom walls of the base). The adjusting gear 7 is connected to the driven gear plate 6 (slidably connected inside the base) and the driving gear plate 9 (fixed to the inner wall of the base) on both sides, forming a linkage transmission structure of "driving gear plate 9-adjusting gear 7-driven gear plate 6". When the second base 2 is pushed and connected along the straight direction of the first base 1, the driving gear plate 9 on the second base 2 enters the inner cavity of the first base 1, meshes with the adjusting gear 7 in the first base 1 and drives it to rotate (the adjusting gear 7 rotates stably through the fixed-point rotating seat 13). Since the driven gear plate 6 and the driving gear plate 9 are meshed on both sides of the adjusting gear 7, its rotation will cause the two to slide in opposite directions - the driving gear plate 9 moves with the direction of the base push, while the driven gear plate 6 slides in the opposite direction, thereby driving the sealing cover plate 11 to slide synchronously.

[0027] The base has a positioning groove 10 on its inner bottom wall. The positioning slide 8 at the lower end of the driven toothed plate 6 is slidably connected in the positioning groove 10 to ensure the stability of the driven toothed plate 6 when it slides. At the same time, the driving toothed plate 9 and the driven toothed plate 6 are set opposite to each other on both sides of the adjusting gear 7 to ensure the accuracy of the transmission direction. As the base is continuously connected, the sealing cover plate 11 gradually slides out from the receiving groove 15 and the clearance groove 14, and finally covers the joint between the first baffle 3 and the second baffle 4. At the same time, the sealing strip 12 is tightly attached to the wall to achieve effective sealing at the joint and avoid the problem of reduced wind resistance, dust prevention and noise reduction performance caused by excessively large joints in traditional enclosures.

[0028] Sealing assembly: A sealing cover plate 11 is fixed to the upper end of the driven toothed plate 6. Its sliding path is subject to double constraints—a receiving groove 15 is formed on the side surface of the base near the sealing cover plate 11, and a clearance groove 14 is formed on the upper end surface. The sealing cover plate 11 slides in both grooves simultaneously. In addition, a sealing strip 12 is fixed to the inner surface of the sealing cover plate 11, and one side of it is attached to the wall of the receiving groove 15 to further improve the sealing performance.

[0029] This structure integrates the traditional step-by-step operation of "docking + sealing" into a synchronous action through the linkage design of "base pushing - gear transmission - cover plate sealing", which greatly saves manpower and time. At the same time, through multiple positioning and sealing components, it ensures the firmness and protective performance of the fence after splicing. It is an ideal solution for the modular and efficient application of temporary fences in civil construction.

[0030] This solution has the following working process: When used in combination, the second base 2 is pushed along the straight line of the first base 1, causing the active toothed plate 9 on the second base 2 to be placed into the inner cavity of the first base 1. The active toothed plate 9 meshes with the adjusting gear 7 in the first base 1 and drives it to rotate. The journal of the adjusting gear 7 rotates in the fixed-point rotating seat 13 embedded in the inner wall of the first base 1. Since the driven toothed plate 6 is meshed with the adjusting gear 7, the rotation of the adjusting gear 7 will cause the driven toothed plate 6 to slide in the opposite direction to the active toothed plate 9. The reverse sliding of the driven toothed plate 6 will cause the sealing cover plate 11 to move in the same direction. As the first base 1 and the second base 2 continuously align, the sealing cover 11 can be simultaneously adjusted to the front of the joint between the first baffle 3 and the second baffle 4. No separate sealing operation is required; simply pushing the base to complete the alignment will automatically trigger the sealing action of the sealing cover 11 through the linkage structure. This reduces the step-by-step process of "alignment + sealing," saving manpower and time. The sealing cover 11 and the sealing strip 12 seal the joint between adjacent baffles, ensuring the protective performance and structural integrity, and reducing the decrease in wind resistance, dust prevention, and noise reduction performance caused by excessively large joints between adjacent baffles.

[0031] During the docking process of the first base 1 and the second base 2, the driven toothed plate 6 and the positioning slide 8 in the second base 2 slide into the inner cavity of the first base 1. In this way, the two bases can achieve the initial positioning function by synchronously inserting the driven toothed plate 6 and the positioning slide 8 during the docking process, thereby reducing the trouble caused by misalignment due to accidental displacement before the first base 1 and the second base 2 are locked with fasteners.
