Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, relates to a new type of recyclable prefabricated fence. Background Technology

[0002] In the fields of building construction, municipal engineering, and housing renovation, construction site fencing plays an indispensable role as a crucial facility for ensuring construction safety and isolating construction areas. It not only effectively prevents unauthorized personnel from entering the work area, improving site safety, but also guides pedestrians and vehicles to slow down by clearly demarcating construction and traffic zones, significantly reducing the probability of traffic accidents. Simultaneously, construction site fencing effectively blocks dust, debris, and noise generated during construction, reducing pollution to the surrounding environment and facilitating site cleaning and tidying after construction is completed.

[0003] However, traditional construction site fencing presents numerous technical problems that urgently need to be addressed. From a structural design perspective, the use of rigid connections such as nails and bolts makes components highly susceptible to damage during frequent disassembly and assembly, resulting in low material recycling rates, resource waste, and increased costs. In terms of functionality, traditional fencing generally has poor sound insulation performance, failing to meet the noise reduction requirements for sensitive areas in the "Environmental Noise Emission Standard for Construction Site Boundaries," leading to a high number of noise pollution complaints. Furthermore, the bottom structure of most traditional fencing has low ground contact, making it ineffective in preventing sewage and dust leakage in complex terrain or uneven road surfaces. Traditional remedial measures such as sealing the bottom with mortar or building retaining walls not only increase construction costs and time but also cause secondary damage to the fencing materials. Utility Model Content

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a novel recyclable prefabricated fencing. By using spring-loaded push-buttons and limiting holes, it solves the problem of damage to the fencing caused by traditional connection methods, improves installation speed, achieves plug-and-play functionality, reduces material damage, lowers construction costs, and improves economic efficiency and environmental friendliness. The composite fencing panel adopts a three-layer composite structure, consisting of two high-strength panels and a sound insulation layer. The outer layer is a 30mm thick high-strength recycled polycarbonate board, and the middle layer is a 30mm thick compressible honeycomb sound insulation cotton, effectively reducing the fencing's weight, improving sound insulation, reducing construction noise, reducing complaints from residents, and improving social benefits. A water-retaining strip made of soft plastic material is installed at the bottom of the panel. Its length matches the panel, and its elasticity allows it to adapt to uneven ground, closely adhering to the ground foundation to effectively prevent water penetration and sewage leakage, improving waterproofing performance and protecting the surrounding environment of the construction site.

[0005] To achieve the above objectives, this utility model provides a novel recyclable prefabricated fencing, comprising at least two uprights, at least two composite fencing panels, at least one support column, and at least two water-retaining strips; wherein...

[0006] Each column is fixedly installed at its bottom with a first fixing plate. The first fixing plate has multiple bolt holes around its perimeter and is fixedly connected to the ground foundation by bolts.

[0007] The support column is located between the two columns, and the two columns and the support column are connected in a straight line. A second fixing plate is fixedly installed at the bottom of the support column. The second fixing plate has multiple bolt holes around its perimeter and is fixedly connected to the ground foundation by bolts.

[0008] The composite fencing panel is installed between the uprights and the support columns, and the bottom of the composite fencing panel is equipped with a water-blocking strip, with its lower surface in direct contact with the ground foundation, thereby forming a waterproof and water-resistant interface.

[0009] Furthermore, each column has two parallel angle steels fixedly installed on its left and right side walls along its length direction. The two parallel angle steels form a limiting groove, and multiple second limiting holes are provided at intervals along the length direction on one of the angle steels.

[0010] Furthermore, the columns are made of 40x80mm square steel tubes with a wall thickness of 4mm and a height of 2.5m. The distance between two adjacent columns is 6m.

[0011] Furthermore, the support column is made of two 20x40mm square steel tubes, which are fixedly installed on the top of the second fixing plate in parallel to each other and form a limiting groove, thus forming the main structure of the support column. Multiple first limiting holes are provided on the side wall of one of the square steel tubes along its length direction, with left and right supports at intervals.

[0012] Furthermore, the composite fencing panel includes a bottom panel, a middle panel, and a top panel. Spring-loaded push-buttons are fixedly installed at intervals on one side wall at both ends of the bottom panel, the middle panel, and the top panel. The installation positions of the spring-loaded push-buttons match the second and first limiting holes on the uprights and support columns, which are used for quick installation and fixation of the composite fencing panel. The bottom panel, the middle panel, and the top panel have the same specifications and dimensions.

[0013] Furthermore, the bottom baffle, middle baffle, and top baffle all adopt a three-layer composite structure, specifically consisting of two high-strength panels and a sound insulation layer sandwiched between them. The outer high-strength panel is made of a 30mm thick high-strength recycled polycarbonate board, while the middle sound insulation layer is made of a 30mm thick compressible honeycomb sound insulation cotton. The outer high-strength panel and the middle sound insulation layer are bonded and fixed together with composite adhesive to form a strong and durable composite structure.

[0014] Furthermore, the bottom baffle, middle baffle, and top baffle have dimensions of 3000×600mm.

[0015] Furthermore, the water-blocking strip includes a connecting block and a base. The base is fixedly installed at the bottom of the connecting block, and its lower surface is in direct contact with the ground foundation. A connecting frame is sleeved on the outside of the connecting block. The connecting frame is a hollow rectangular structure with a vertical height greater than that of the connecting block, and an extension limiting part is formed at the top. The bottom baffle can be vertically inserted along the hollow rectangular structure of the connecting frame. The bottom baffle and the water-blocking strip are connected by a gap fit between the extension limiting part of the connecting frame and the side wall of the bottom baffle.

[0016] Furthermore, the water-blocking strip is made of soft plastic material, and its length matches that of the composite fencing panel.

[0017] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0018] (1) The recyclable prefabricated fence of this utility model completely solves the problem of damage to the fence caused by the traditional nail and bolt connection method by using spring-type press buttons and limit holes in combination, improves the installation speed, realizes the plug-and-play effect, reduces the damage to the fence material, makes the fence material reusable, reduces construction costs, and improves the economy and environmental protection of the material.

[0019] (2) The recyclable prefabricated fence of this utility model adopts a three-layer composite structure through the composite fence panel, specifically consisting of two high-strength panels and a sound insulation layer sandwiched between them. The outer high-strength panel is made of high-strength recycled polycarbonate board with a thickness of 30mm, and the middle sound insulation layer is made of compressible honeycomb sound insulation cotton with a thickness of 30mm. This solves the problems of heavy weight, high transportation cost and noise pollution of traditional fences, significantly improves the sound insulation effect, reduces construction noise, reduces interference to surrounding residents, thereby reducing complaints about noise pollution and improving the social benefits of construction.

[0020] (3) The recyclable prefabricated fence of this utility model has a water-blocking strip set at the bottom of the bottom baffle.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1-4 As shown, this utility model provides a novel recyclable prefabricated fencing, which includes at least two uprights 1, at least one composite fencing panel 2, at least one support column 3, and at least two water-retaining strips 4. It should be noted that... Figure 1 The following example uses two columns 1, two composite fencing panels 2, one support column 3, and two water-blocking strips 4 for illustration.

[0028] like Figure 1 As shown, each column 1 is fixedly installed with a first fixing plate 10 at its bottom. The first fixing plate 10 has multiple bolt holes around its perimeter and is fixedly connected to the ground foundation by bolts to play a key supporting and fixing role for the entire fence. The tight connection between the first fixing plate 10 at the bottom of the column 1 and the ground foundation ensures that the fence structure can remain stable under various working conditions, thereby ensuring the normal use function and safety of the fence and providing reliable protection and isolation for the environment where the fence is located.

[0029] Furthermore, a support column 3 is provided between every two columns 1, and the two columns 1 and the support column 3 are connected in a straight line. A second fixing plate 11 is fixedly installed at the bottom of the support column 3. The second fixing plate 11 has multiple bolt holes around its perimeter and is fixedly connected to the ground foundation by bolts to play a key supporting and fixing role for the entire fence, ensuring that the fence structure can remain stable under various working conditions, thereby ensuring the normal use function and safety of the fence.

[0030] Furthermore, the support column 3 is made of two 20x40mm square steel tubes, which are fixedly installed parallel to each other on the top of the second fixing plate 11 to form a limiting groove, thus forming the main structure of the support column 3. Multiple first limiting holes 7 are provided on the side wall of one of the square steel tubes along its length direction, which facilitates subsequent installation and fixing. This allows the support column 3 to be accurately connected and positioned with other components, which not only enhances the structural stability of the support column 3, but also improves its flexibility and adaptability in practical applications.

[0031] Furthermore, two parallel angle steels 6 are fixedly installed on the left and right side walls of each column 1 along its length. The two parallel angle steels 6 form a limiting groove, and multiple second limiting holes 8 are provided at intervals along the length of one of the angle steels 6 for installing the composite fence baffle 2. The limiting groove and the second limiting holes 8 make the composite fence baffle 2 quick to install, position adjustable, easy to maintain and replace, reduce maintenance costs, and improve service life.

[0032] Furthermore, a composite fencing panel 2 is provided between the upright column 1 and the support column 3. The composite fencing panel 2 includes a bottom panel 21, a middle panel 22, and a top panel 23. Spring-loaded push-buttons 5 are fixedly installed at intervals on one side wall at both ends of the bottom panel 21, the middle panel 22, and the top panel 23. The installation position of the spring-loaded push-buttons 5 matches the second limiting hole 8 and the first limiting hole 7 on the upright column 1 and the support column 3, which is used for quick installation and fixation of the composite fencing panel 2. The bottom panel 21, the middle panel 22, and the top panel 23 are all precisely inserted into the limiting groove between the upright column 1 and the support column 3 from bottom to top through embedded sequentially, forming a stable longitudinal splicing system. Moreover, the bottom panel 21, the middle panel 22, and the top panel 23 have the same specifications and dimensions, ensuring the neatness of the overall appearance of the fencing and the convenience of installation.

[0033] Specifically, when installing the bottom baffle 21, the middle baffle 22, and the top baffle 23, first align them with the limiting grooves on the uprights 1 and the support columns 3, and slowly insert them. During the insertion process, the external force applied by the installer will cause the spring-type push buttons 5 located on both sides of the baffle to enter the compressed state from their original position. At this time, the spring is compressed and stores energy. When the baffle continues to be inserted, when the spring-type push buttons 5 reach the position of the first limiting hole 7 or the second limiting hole 8, the external force disappears, and the spring releases energy under its own restoring action, pushing the push buttons 5 to quickly pop out from the first limiting hole 7 or the second limiting hole 8 and lock into the first limiting hole 7 or the second limiting hole 8 to form a mechanical limit. Thus, the composite fence baffle 2 is firmly fixed between the uprights 1 and the support columns 3, ensuring the integrity and stability of the fence structure.

[0034] Furthermore, the bottom baffle 21, the middle baffle 22, and the top baffle 23 all adopt a three-layer composite structure, specifically consisting of two high-strength panels and a sound insulation layer sandwiched between them. The outer high-strength panel is made of 30mm thick high-strength recycled polycarbonate board, which possesses excellent mechanical properties and weather resistance. The middle sound insulation layer is made of 30mm thick compressible honeycomb sound insulation cotton, whose unique honeycomb structure effectively absorbs and blocks sound transmission, thus achieving good sound insulation. The outer high-strength panel and the middle sound insulation layer are bonded and fixed together with composite adhesive, forming a strong and durable composite structure.

[0035] Furthermore, the bottom baffle 21, the middle baffle 22, and the top baffle 23 all adopt a standardized length and width design, with a uniform size of 3000mm × 600mm. This size parameter is set based on comprehensive considerations of engineering installation, transportation, and mechanical performance: the 3000mm length increases the protective coverage area of ​​a single baffle, effectively reducing splicing gaps and thus improving the overall sound insulation and protective performance of the enclosure; while the 600mm width ensures uniform stress distribution within the baffle under external loads such as wind pressure and impact forces.

[0036] Furthermore, a water-blocking strip 4 is provided at the bottom of the bottom baffle 21. The water-blocking strip 4 includes a connecting block 41 and a base 42. The base 42 is fixedly installed at the bottom of the connecting block 41, and its lower surface is in direct contact with the ground foundation, thus forming an initial waterproof and water-blocking interface. A connecting frame 9 is fitted on the outside of the connecting block 41. The connecting frame 9 is a hollow rectangular structure with a vertical height greater than that of the connecting block 41, and an extension limiting part is formed at the top. The bottom baffle 21 can be vertically inserted along the hollow rectangular structure of the connecting frame 9. The gap between the extension limiting part of the connecting frame 9 and the side wall of the bottom baffle 21 is used to realize the insertion connection between the bottom baffle 21 and the water-blocking strip 4. At the same time, the inner wall of the connecting frame 9 is provided with at least one annular sealing protrusion or elastic sealing strip. When the bottom baffle 21 is inserted, the sealing protrusion or strip is squeezed and deformed, further enhancing the connection stability between the connecting frame 9 and the bottom baffle 21.

[0037] Furthermore, the water-blocking strip 4 is made of soft plastic material, and its length matches that of the composite fence panel 2, allowing it to fit tightly against the bottom of the panel and form a seamless connection, further enhancing the sealing performance of the fence. In addition, the soft plastic material has a certain degree of elasticity, which can adapt to the unevenness of the ground foundation, ensuring that the water-blocking strip 4 is in close contact with the ground foundation and improving the waterproofing effect.

[0038] Furthermore, the column 1 is made of 40x80mm square steel pipe with a wall thickness of 4mm and a height of 2.5m. The distance between two adjacent columns 1 is 6m.

[0039] This utility model discloses a novel recyclable prefabricated fencing system. By employing a connection method that combines spring-loaded push-buttons with limiting holes, it effectively solves the damage problems caused by traditional connection methods, improves installation speed, achieves plug-and-play functionality, reduces material damage, lowers construction costs, and enhances both economic efficiency and environmental friendliness. The composite fencing panels utilize a three-layer composite structure: an outer 30mm thick high-strength recycled polycarbonate board, a middle 30mm thick compressible honeycomb sound insulation cotton, and a structure that not only reduces the fencing's weight but also enhances sound insulation, reduces construction noise, minimizes complaints from residents, and improves social benefits. The bottom baffle is equipped with a water-blocking strip made of soft plastic material. Its length matches the baffle, and its elasticity allows it to adapt to uneven ground, ensuring a tight fit against the foundation and effectively preventing water penetration and sewage leakage. This enhances waterproofing performance and protects the surrounding environment of the construction site. Furthermore, the columns and support columns adopt a standardized design. The columns use 40x80mm square steel pipes with a wall thickness of 4mm, a height of 2.5m, and a spacing of 6m. The composite fencing panels are uniformly 3000mm×600mm in size, facilitating installation and maintenance, improving construction efficiency, and reducing construction costs.

[0040] In another embodiment of this utility model, a method for installing a recyclable prefabricated fence is provided, comprising the following steps: First, bolts are used to connect the upright 1 to the ground foundation via the first fixing plate 10 and the support column 3 via the second fixing plate 11; then, the water-blocking strip 4 is installed between the upright 1 and the support column 3, so that the base 42 is in close contact with the ground; then, the connecting frame 9 is sleeved on the outside of the connecting block 41; subsequently, the bottom baffle 21 is inserted into the limiting groove between the upright 1 and the support column 3, ensuring that the bottom of the bottom baffle 21 is inserted into the connecting frame 9; then, the middle baffle 22 and the top baffle 23 are inserted into the limiting groove between the upright 1 and the support column 3 in sequence; finally, during the insertion of the baffles, the spring-loaded push button 5 automatically pops out and locks into the corresponding limiting hole under the restoring action of the spring, thereby completing the fixed installation of the baffles.

[0041] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
