Description

Technical Field

[0001] This utility model belongs to the technical field of road construction auxiliary equipment, and more specifically, it relates to a temporary construction fence for road construction. Background Technology

[0002] During temporary road construction, construction site fencing is a key piece of equipment for ensuring construction safety and traffic order. Existing fencing mainly uses anchor bolts to fix the base to the road surface, which requires pre-drilling holes. This not only damages the road structure, but also requires repairing the holes after dismantling, increasing construction costs and time. Secondly, the fencing units are mostly connected by bolts, and installation and dismantling require the use of specialized tools such as wrenches and electric drills, which is time-consuming, labor-intensive, and requires multiple people to work together.

[0003] To address this, patent CN222835526U discloses a road construction temporary enclosure structure that can be quickly assembled, disassembled, and reused. By setting a base to support the structure above it, and utilizing the set rotating rods, connecting blocks, limiting blocks, T-shaped sliding seats, sliding grooves, and slots, the structure, in conjunction with the external enclosure components of the base, facilitates the temporary assembly and enclosure of road construction, while also enabling the quick assembly and disassembly of the entire enclosure. This avoids the damage caused by traditional bolt-type assembly and disassembly, effectively improving the overall reuse rate of the enclosure.

[0004] However, the above structure still has the following shortcomings: 1. The vertical poles of the fence assembly are only vertically positioned through the "bottom end snap-fit ​​slot" without any additional vertical locking structure, and there is no horizontal splicing structure between adjacent fence units, resulting in insufficient overall strength of the fence assembly. Under the action of external force or wind, the vertical poles are prone to shift or tilt from the slot, thus causing the fence to deform as a whole; 2. The connecting block requires two people to work together by "rotating the lever + pressing down the extension block". The threads are prone to getting dusty and jamming, making disassembly and assembly time-consuming and laborious; 3. The rotating rod has no anti-loosening structure. It is prone to self-rotation under vibration, causing the connecting block to move upward and the fence to loosen. In addition, the connecting block and rotating rod are independent small parts in the structure, and parts are prone to being lost after disassembly and assembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a temporary construction fence for road construction. It realizes the three-dimensional fixation of the fence panel and the support frame at the top, middle and bottom, and is easy to assemble and disassemble. No professional equipment and complicated tools are required for installation, which greatly reduces the labor input and construction time cost, and meets the needs of temporary construction for "installation and use and disassembly and departure".

[0006] The aforementioned temporary construction site fence for road construction includes multiple fence panels. A support frame is provided on the back of adjacent fence panels. A locking seat for fixing adjacent fence panels and the support frame is rotatably connected to one end of the top of the fence panel.

[0009] Preferably, the locking block includes a triangular plate, which is a right triangle. The inclined surface of the triangular plate is opposite to the adjacent locking seat, the top of the triangular plate is smoothly transitioned, and a locking hole is provided on the upper part of the triangular plate.

[0010] Preferably, the locking seat includes a rotating shaft connected to the upper part of the enclosure plate. A fixed frame and a locking bracket are rotatably connected on the rotating shaft. The locking bracket can cover the upper part of the adjacent enclosure plate, and the locking bracket has a long locking hole that cooperates with the locking block. The fixed frame can be fitted onto the outside of the longitudinal beam. An unlocking plate is fixedly connected between the fixed frame and the locking bracket. The bottom of the unlocking plate is provided with anti-slip texture.

[0011] Preferably, the top of the longitudinal beam is provided with a ramp, which is arranged opposite to the locking seat.

[0012] Preferably, the crossbeam is provided with a split counterweight, which includes a counterweight box one and a counterweight box two. The counterweight box one and the counterweight box two are connected by a dovetail block and a connecting block that engage with each other.

[0017] 2. Foldable barriers are added at the corners of the construction site. The barrier frame can be adjusted by hinges to open and close at different angles, making it easy to adapt to different construction areas such as straight lines and corners, and making it more flexible to use.

[0018] 3. A split counterweight is added to the bottom of the support frame, which facilitates installation, transportation and disassembly. The counterweight weight can be flexibly adjusted according to the wind level. The limiting hole can be used to fix the counterweight with positioning pins or to connect to anchor bolts to achieve long-term rigid fixation, taking into account both temporary and long-term construction needs and reducing equipment procurement and maintenance costs.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figures 1 to 12 As shown, a temporary construction site fence for roads includes multiple fence panels 1. These panels are joined together to form a continuous barrier, physically separating the construction area from external roads and pedestrian areas, preventing the spread of construction dust and noise, and preventing unauthorized personnel from entering dangerous areas, thus ensuring construction safety and public order. Support frames 2 are provided on the back of adjacent fence panels 1. These support frames 2 serve as the load-bearing structure of the fence, bearing the vertical and lateral wind loads of the fence panels 1, preventing them from bending or tipping due to their own weight or external forces, improving the overall structural stability of the fence, and preventing damage caused by individual fence panels 1 bearing independent forces. A locking seat 5 is rotatably connected to the top of each fence panel 1 for fixing adjacent fence panels 1 and support frames 2. The locking seat 5 can rotate around the top of the fence panel 1, facilitating automatic locking of adjacent fence panels 1 and support frames 2 when they are joined, achieving automatic connection of the three and improving overall stability. The other end of the top of the enclosure panel 1 is fixedly connected to a locking block 4 that cooperates with the adjacent locking seat 5. The locking block 4 is a cooperating part of the locking seat 5. When adjacent enclosure panels 1 are spliced, the locking seat 5 can be fitted onto the locking block 4, and the relative movement of the top of the adjacent enclosure panels 1 is restricted through mechanical cooperation to prevent the splice from loosening.

[0023] like Figure 6As shown, the support frame 2 includes vertically arranged longitudinal beams 201 and transverse beams 205. A diagonal brace 203 is fixedly connected between the longitudinal beams 201 and transverse beams 205. A reinforcing rib 204 is welded between the diagonal brace 203 and the transverse beams 205 to enhance the connection strength. The diagonal brace 203, longitudinal beams 201, and transverse beams 205 form a triangular stable structure, effectively dispersing the shear force and torque between the longitudinal beams 201 and transverse beams 205, preventing deformation of the support frame 2 due to lateral wind or impact forces, and significantly improving the deformation resistance rigidity of the support frame 2. A bottom positioning frame 206 is fixedly connected to the lower end of the longitudinal beams 201 for locking and limiting adjacent enclosure panels 1. The bottom positioning frame 206 limits the lateral displacement of the bottom of adjacent enclosure panels 1 through locking, while simultaneously ensuring that the enclosure panels 1 stand vertically through limiting action, preventing the bottom from tilting; and in conjunction with the top locking seat 5 and locking block 4, achieves double-point fixing of the enclosure panels from the top and bottom, preventing the entire enclosure from tipping over.

[0024] like Figure 1 and Figure 9 As shown, the fence panel 1 includes a frame 102, which is the skeleton of the fence panel 1. It is preferably made of square steel pipe to ensure that the fence panel 1 itself is not easily bent or damaged, thereby improving the structural strength of a single fence panel 1. A color steel plate 101 is fixed to the side of the frame 102 away from the support frame 2. At least one support beam 103 is fixedly connected between the two sides of the frame 102. The support beam 103 can distribute the lateral load borne by the frame 102 and prevent the frame 102 from bending and deforming in the middle due to its large span. The longitudinal section of the bottom positioning frame 206 is U-shaped, forming a slot-type accommodating space, which facilitates the quick insertion of the frame 102 and the color steel plate 101 of the enclosure 1, realizing immediate insertion and positioning, reducing the adjustment time during installation, and improving the efficiency of disassembly and assembly. The width of the U-shaped structure matches the thickness of the frame 102 and the color steel plate 101, ensuring that after the frame 102 and the color steel plate 101 are inserted, they fit tightly against the inner wall of the U-shaped structure without gaps, preventing the enclosure 1 from swaying left and right in the bottom positioning frame 206, and further strengthening the stability of the bottom fixation.

[0025] Furthermore, frame 102 can be made up of two half-frames connected by hinges. When the fence needs to turn or change angle, the opening angle of the half-frames can be opened, which is convenient to use.

[0026] like Figure 1 and Figure 4As shown, a U-shaped pin 207 is rotatably connected to the longitudinal beam 201 near its center. The U-shaped pin 207 is a detachable connecting shaft between the enclosure panel 1 and the support frame 2. The U-shaped structure is easier to grip, and under the action of gravity, both ends automatically rotate downwards, making it less likely to fall off after insertion. This enables quick assembly and disassembly of the enclosure panel 1 and the support frame 2, improving the convenience of enclosure assembly and disassembly. Ear plates 104 corresponding to the U-shaped pin 207 are fixedly connected to both sides of the frame 102. The ear plates 104 are located on the sides of the longitudinal beam 201. On one hand, the ear plates 104 provide precise mating holes for the U-shaped pin 207, ensuring that the connection position of the enclosure panel 1 and the longitudinal beam 201 is aligned, preventing wobbling between the enclosure panel 1 and the support frame 2 due to gaps, and improving connection stability. On the other hand, they can distribute the force on the U-shaped pin 207, preventing direct force on the frame 102 and causing localized damage, thus extending the service life of the enclosure panel 1. The ear plate 104 has an elongated hole 1041 that mates with the U-shaped pin 207. The elongated hole 1041 facilitates the passage of both ends of the U-shaped pin 207, improving the efficiency of disassembly and assembly.

[0027] like Figure 3 As shown, the locking block 4 includes a triangular plate 401, which is a right triangle, enhancing the structural strength of the locking block 4 itself. The inclined surface of the triangular plate 401 is positioned opposite to the adjacent locking seat 5, providing a guiding function for the locking seat 5: when the locking seat 5 rotates to engage with the locking block 4, the inclined surface guides the locking seat 5 to quickly slide into the mating position, eliminating the need for precise alignment and reducing operational difficulty, making it particularly suitable for rapid installation needs on construction sites. The top of the triangular plate 401 has a smooth transition, preventing jamming or scratches caused by sharp edges when the locking seat 5 is engaged, improving operational smoothness and extending the number of reuses. Furthermore, a locking hole 402 is provided at the top of the triangular plate 401. When the enclosure is temporarily installed, it is not necessary to install a lock in the locking hole 402; when the enclosure needs to be used for a long time, a lock can be inserted into the locking hole 402 to achieve a rigid connection between the locking seat 5 and the locking block 4, preventing separation and ensuring that the top of the adjacent enclosure panel 1 is securely fixed and does not loosen.

[0028] like Figure 2 As shown, the locking seat 5 includes a rotating shaft 504, which is connected to the upper part of the enclosure plate 1. The rotating shaft 504 is the fulcrum for the rotation of the locking seat 5. A fixed frame 501 and a locking bracket 503 are rotatably connected to the rotating shaft 504. Figure 8As shown, a limiting pin 105 is fixed on the frame 102 to limit the locking frame 503. The fixing frame 501 can be sleeved on the outside of the longitudinal beam 201 to connect the locking seat 5 to the longitudinal beam 201 of the support frame 2, thereby fixing the top of the enclosure to the support frame 2 and preventing the support frame 2 from detaching from the enclosure plate 1, forming a double-point support from the top and bottom. The locking frame 503 can cover the upper part of the adjacent enclosure plate 1, restraining the vertical displacement of the enclosure plate 1 from above to prevent the top from tilting up; and restraining the lateral displacement to prevent the splice from separating, forming a two-way locking with the fixing frame 501. In addition, the locking frame 503 is provided with a long locking hole 505 that mates with the locking block 4. The long locking hole 505 can accommodate the positional deviation of the locking block 4, allowing the locking block 4 to move slightly in the hole, ensuring reliable mating even if there are installation errors, and providing a hole position for subsequent locking. The fixed frame 501 can be fitted onto the outside of the longitudinal beam 201. An unlocking plate 502 is fixedly connected between the fixed frame 501 and the locking frame 503. The unlocking plate 502 enhances the connection strength between the fixed frame 501 and the locking frame 503. Furthermore, when unlocking is required, the entire locking seat 5 can be reversed by pushing the unlocking plate 502 upwards with a long rod, achieving one-step unlocking and simplifying the construction process. The bottom of the unlocking plate 502 has anti-slip textures to increase friction, prevent slippage, ensure safe and reliable operation, and reduce disassembly and assembly errors caused by slippage.

[0029] The top of the longitudinal beam 201 is provided with a ramp 202, which is positioned opposite to the locking seat 5. The ramp 202 serves as a guide. When the fixing frame 501 rotates around the pivot 504 and slides onto the top of the longitudinal beam 201, the ramp 202 can guide the fixing frame 501 to slide quickly into the outside of the longitudinal beam 201, avoiding a hard collision between the fixing frame 501 and the top of the longitudinal beam 201, protecting the surface of the components, reducing installation resistance, and improving operational smoothness.

[0030] like Figure 10 and Figure 11 As shown, a split counterweight 3 is installed on the crossbeam 205. During use, water or sand can be injected into the split counterweight 3 to increase the weight at the bottom of the support frame 2, thereby improving the overall overturning resistance of the fence. This effectively counteracts the overturning effect of lateral wind or impact forces, preventing the fence from being blown down or knocked over. It is especially suitable for temporary construction scenarios without anchor bolts. The hollow split counterweight 3 solves the problems of difficult handling and installation of the overall counterweight.

[0031] Specifically, the split counterweight 3 includes counterweight box one 31 and counterweight box two 32. Counterweight box one 31 and counterweight box two 32 are connected by a dovetail block 33 and a connecting block 34 that engage in a snap-fit ​​configuration. The snap-fit ​​between the dovetail block 33 and the connecting block 34 enables quick assembly and prevents detachment. The dovetail structure has a one-way locking property, making it difficult for the two counterweight boxes to separate laterally after assembly, ensuring that the two counterweight boxes form a whole and are stably placed on the crossbeam. At the same time, the detachable design allows for easy replacement of damaged counterweight boxes, improving the reuse rate. During manufacturing, the dovetail block 33 is fixedly connected to counterweight box one 31, and the connecting block 34 is fixedly connected to counterweight box two 32. The connecting block 34 has a dovetail groove 35 that mates with the dovetail block 33. The precise fit between the dovetail groove 35 and the dovetail block 33 restricts the relative displacement of the first counterweight box 31 and the second counterweight box 32, ensuring overall stability and preventing wobbling after assembly. At the same time, the inclined surface of the dovetail groove 35 can guide the dovetail block 33 to be inserted quickly, improving the assembly efficiency.

[0032] The bottom of the connecting block 34 is provided with a mounting groove that matches the crossbeam 205. The mounting groove enables precise positioning of the counterweight, preventing the counterweight from shifting due to vibration or wind, and ensuring that the counterweight always acts on the crossbeam 205.

[0033] Multiple limiting holes 2051 are provided on the crossbeam 205, and positioning pins 208 are installed in the limiting holes 2051 to limit the position of the split counterweight 3. The limiting holes 2051 are distributed along the length of the crossbeam 205, allowing the position of the positioning pins 208 to be adjusted according to the number of counterweight boxes or the total length, adapting to split counterweights of different lengths and improving versatility; the positioning pins 208, together with the mounting groove, achieve bidirectional fixation of the counterweight box, ensuring that the counterweight does not slip and further enhancing anti-overturning stability. Secondly, when the enclosure needs to be used for a long time, the limiting holes 2051 can also be used with anchor bolts to achieve rigid fixation.

[0034] In this embodiment, both counterweight box 1 (31) and counterweight box 2 (32) include a box body (301). The box body (301) provides a stable space for the counterweight material, which can be water, sand, gravel, iron blocks, etc. A sealing cover (302) is rotatably connected to the top of the box body (301) via a hinge. The sealing cover (302) is quickly sealed and fixed by a latch (303). The sealing cover (302) facilitates the filling of the box body with sand or gravel-like counterweight material. When closed, it prevents rainwater and dust from entering the box body, avoiding moisture or rusting of the counterweight material, and also prevents material leakage (such as granular materials), ensuring stable counterweight weight. An outlet is provided on one side of the box body (301). The outlet is used to empty the counterweight material from the box body after construction (e.g., to recycle sand and gravel, or drain water), making the counterweight box lightweight and facilitating transportation and storage. A sealing plug (304) is sealed to the outlet. The sealing plug (304) seals the outlet when filling with counterweight to prevent material leakage; it can be pulled out when emptying, making operation simple while ensuring the box body's airtightness and improving the reusability of the counterweight box.

[0035] The installation process of this utility model is as follows: 1. For example Figure 5 and Figure 12 As shown, after cleaning the construction area, using the boundary line of the construction area as a reference, first move at least three support frames 2 to the installation position, adjust the position of the support frames 2 to ensure that the U-shaped groove of the bottom positioning frame 206 on the longitudinal beam 201 is facing upwards and toward the installation side of the fence panel 1. Then, one person lifts the fence panel 1 vertically, aligning the bottom of the frame 102 with the U-shaped groove of the bottom positioning frame 206, and slowly inserts it until the bottom of the frame is flush with the bottom wall of the U-shaped groove. After insertion, the fence panel 1 automatically achieves bottom limiting, requiring no additional fixing.

[0036] 2. Simultaneously, another person rotates the U-shaped pin 207 in the middle of the longitudinal beam 201 upwards to overcome the gravity-induced anti-detachment effect, and pulls the U-shaped pin 207 away from the end of the enclosure panel 1. As the enclosure panel 1 approaches, the end of the U-shaped pin 207 rotates and aligns with the elongated holes 1041 on the ear plates 104 on both sides of the enclosure panel frame 102. The U-shaped pin 207 is then pushed, allowing its end to pass through the elongated holes 1041. The U-shaped pin 207 is then lowered, and under gravity, both ends automatically rotate downwards, completing the vertical rigid connection between the enclosure panel 1 and the support frame 2. The above actions are repeated when installing adjacent enclosure panels 1.

[0037] 3. Install the second fence panel according to the procedure in step 2, ensuring that its bottom frame is inserted into the bottom positioning frame 206 of the adjacent support frame 2, and that the tops of the two fence panels 1 are aligned; if it is a corner position, use a folding fence panel 1 with hinges, and adjust the angle of the half-frame hinge of the fence panel frame 102.

[0038] 4. When adjacent fence panels 1 are spliced, as the second fence panel 1 approaches the first fence panel 1, the bottom of the fixing frame 501 on the locking seat 5 is guided along the ramp 202, causing the entire locking seat 5 to rotate around the pivot 504. The fixing frame 501 slides into the outside of the longitudinal beam 201 along the ramp 202 at the top of the longitudinal beam 201. At the same time, the locking frame 503 gradually covers the top of the second fence panel 1 under the guidance of the triangular plate 401 until the long locking hole 505 on the locking frame 503 is completely engaged with the triangular plate 401 of the second fence panel 1, without the need for precise alignment. When the bottom of the locking frame 503 is in contact with the top of the fence panel 1, the initial locking is completed. At this time, the two ends of the fence panel 1 are temporarily supported and fixed by two support frames 2, making it less likely to tip over.

[0039] If the fence is to be used for a long time, a lock, such as a padlock, can be passed through the locking hole 402 of the locking block 4 to achieve rigid locking and prevent unauthorized personnel from accidentally unlocking it.

[0040] 5. Align the dovetail block 33 of counterweight box 1 31 with the dovetail groove 35 of the connecting block 34 of counterweight box 2 32 and push it in to form an integral counterweight unit. The mounting groove at the bottom of the connecting block 34 automatically engages with the crossbeam 205, achieving initial positioning of the counterweight unit. Open the sealing cover 302 on the top of the counterweight box and fill the box with sand or water. After filling, close the sealing cover to prevent material leakage. Finally, insert the positioning pin 208 into the limiting hole 2051 of the crossbeam 205, pressing against the side of the counterweight box to restrict the counterweight unit from sliding along the length of the crossbeam 205. For long-term construction, anchor bolts can be driven into the limiting hole to fix the crossbeam 205 to the ground, further improving the anti-overturning ability.

[0041] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
