Description

Technical Field

[0001] This utility model relates to the field of municipal fencing technology, and in particular to a prefabricated, foundation-free municipal fencing. Background Technology

[0002] Traditional fencing relies on foundations or expansion bolts for fixation, resulting in low reuse rates and easy damage after repeated disassembly and reassembly. Foundation-free fencing generally suffers from insufficient stability, especially in northern regions where strong winds are frequent in spring and autumn. It is difficult to withstand strong wind loads and poses significant safety hazards. Existing foundation-free fencing uses multiple counterweights, which are mostly placed separately and lack effective integration and restraint structures. This makes it easy for the counterweights to shift relative to each other, failing to form a stable whole. This not only weakens the counterweight fixing effect and affects the wind resistance of the fencing, but may also cause safety accidents due to the counterweights tipping over or shifting.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1, referring to Figures 1-6 This is the first embodiment of the present invention, which provides a prefabricated, foundation-free municipal fence. The prefabricated, foundation-free municipal fence includes a main component 1, including a column 11. A fence 12 is bolted to the column 11. The fence 12 is welded from multiple galvanized square tubes. One column 11 connects two fences 12. A color steel plate 13, which is galvanized steel plate, is bolted to one side of the fence 12. A base rod 14 is welded to the column 11. A diagonal brace 15 is welded to the column 11. The diagonal brace 15 is connected to the base rod 14 by welding. The column 11, the base rod 14, and the diagonal brace 15 are all galvanized square tubes. The three together form a triangle to improve stability. They are integrally welded for easy installation and disassembly.

[0030] The fixing component 2, located on the base pole 14, includes a fixing member 21 located on the base pole 14. The fixing member 21 is used to stably fix the entire fence structure in a designated position without foundation design and without damaging the original structural surface layer.

[0031] The fixing component 21 includes multiple counterweights 211 set on the base rod 14. An outer platform 212 is fixed on the base rod 14. The outer platform 212 is located on the base rod 14 away from the fence 12. The counterweights 211 are precast C30 concrete counterweights with high strength and can be reused more than 4 times. The weight of a single counterweight 211 is 25kg. The total number of counterweights 211 is 20. Under the gravity of the counterweights 211, the fence structure can be stably fixed on the ground. The outer platform 212 is a reserved stacking position for the counterweights 211.

[0032] The fixing component 2 also includes a limiting member 22 disposed on the bottom rod 14. The limiting member 22 is used to restrict the multiple counterweights 211 within the rectangular frame, so that the multiple counterweights 211 form a whole and prevent the individual counterweights 211 from shifting or tipping over.

[0033] The limiting component 22 includes a base 221 disposed on the outer platform 212. The size of the base 221 corresponds to that of the outer platform 212. A column 222 is welded on the base 221. There are multiple columns 222. The base 221 and the column 222 together form a rectangular frame. The frame provides a regular placement space to accommodate multiple counterweights 211.

[0034] A rectangular groove 221-1 is provided on the base 221. A lifting plate 223 is slidably arranged in the rectangular groove 221-1. A counterweight 211 can be placed on the lifting plate 223. In the initial state, the lifting plate 223 is located in the initial upper position. As the counterweight 211 is placed, the lifting plate 223 will gradually move downward.

[0035] Example 2, refer to Figures 4-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the outer platform 212 has a positioning groove 212-1, and the base 221 has a positioning post 224 fixed on it. The positioning post 224 can be inserted into the positioning groove 212-1. There are two positioning posts 224 fixed on one base 221. When the base 221 is placed on the outer platform 212, the positioning post 224 needs to be aligned with the positioning groove 212-1. Then the base 221 is lowered and the two positioning posts 224 are inserted into the corresponding positioning groove 212-1.

[0037] Specifically, multiple first elastic pads 225 are fixed to the inner wall of the rectangular groove 221-1. The other end of the first elastic pad 225 is fixed to the lifting plate 223. The first elastic pad 225 has elastic deformation capability. The first elastic pad 225 is used to apply a continuous thrust to the lifting plate 223, so that in the initial state, the lifting plate 223 is located in the initial upper position. As the counterweight 211 is placed, the lifting plate 223 will gradually move downward, and the first elastic pad 225 will be gradually compressed.

[0038] Specifically, the fixing component 2 also includes a locking member 23 located at the bottom of the lifting plate 223. The locking member 23 is configured to lock the relative position of the base 221 and the outer platform 212.

[0039] The locking component 23 includes a pressing block 231 fixed to the bottom of the lifting plate 223, a moving groove 224-1 provided on the positioning column 224, a locking block 232 slidably disposed in the moving groove 224-1, and a locking groove 212-2 corresponding to the locking block 232 provided on the outer platform 212.

[0040] When the lifting plate 223 moves downward, it will synchronously drive the pressing block 231 to move downward. In the initial state, the locking block 232 is located inside the positioning post 224. As the pressing block 231 moves downward, it will trigger the locking block 232 to move along the moving groove 224-1 to the outside of the positioning post 224, and finally engage with the locking groove 212-2. When the two are engaged, the base 221 cannot be separated from the outer platform 212. Only after the counterweight block 211 is completely removed, the lifting plate 223 is reset, and the locking block 232 moves back into the positioning post 224, can the base 221 and the outer platform 212 be separated.

[0041] Specifically, the positioning post 224 has a through groove 224-2 corresponding to the pressing block 231. The through groove 224-2 is configured to provide a channel for the pressing block 231 to move downward and approach the locking block 232.

[0042] Specifically, one end of the extrusion block 231 is inclined, and the locking block 232 has an inclined surface 232-1. The extrusion block 231 can contact the inclined surface 232-1. By setting it in an inclined manner, in the initial state, the lifting plate 223 is located at the upper position, and at this time the extrusion block 231 will not contact the inclined surface 232-1.

[0043] As the lifting plate 223 moves the pressing block 231 downward, the inclined end face at the bottom of the pressing block 231 will first contact and press the inclined surface 232-1 of the locking block 232, thereby applying a pushing force to the locking block 232, causing it to move along the moving groove 224-1 towards the outside of the positioning post 224, and engage with the locking groove 212-2.

[0044] Example 3, referring to Figures 1-7This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the locking block 232 has extension blocks 233 fixed on both sides, and the positioning post 224 has a sliding groove 224-3 corresponding to the extension blocks 233. When the locking block 232 slides in the moving groove 224-1, the two extension blocks 233 will also slide synchronously in the sliding groove 224-3.

[0046] Specifically, one end of the extension block 233 is fixed with a second elastic pad 234, and the other end of the second elastic pad 234 is fixed to the inner wall of the slide groove 224-3. The number of second elastic pads 234 corresponds to the extension block 233. The second elastic pad 234 has elastic deformation capability. When there is no other external force, the second elastic pad 234 applies a continuous pushing force to the extension block 233, so that the locking block 232 is completely located inside the positioning post 224. When the inclined surface 232-1 of the locking block 232 is subjected to pressure and moves towards the locking groove 212-2, the second elastic pad 234 is compressed. After the external force disappears, the second elastic pad 234 can drive the locking block 232 to reset and be completely located inside the positioning post 224 again, without hindering the separation of the positioning post 224 and the positioning groove 212-1.

[0047] Specifically, an upper color steel plate 235 is movably connected to the upright 222. The upright 222 and the upper color steel plate 235 are bolted together. The upper color steel plate 235 can limit the top of the stacked counterweight 211. The upper color steel plate 235 has a threaded groove, and the corresponding upright 222 also has a corresponding threaded groove. Through the cooperation of bolts, the connection between the upper color steel plate 235 and the upright 222 is finally completed. The upright 222, the base 221 and the upper color steel plate 235 will form a complete rectangular frame. Multiple counterweights 211 are neatly placed in it. The frame organizes the stacking method of the counterweights 211, effectively controls the stacking height of the counterweights while ensuring stability, avoids excessive occupation of construction space, and adapts to the needs of complex construction sites and dense traffic in municipal engineering.

[0048] Specifically, an inner platform 213 is welded onto the base rod 14. The inner platform 213 is located on the base rod 14 near the enclosure 12. The inner platform 213 is also equipped with a base 221 and an upright 222. The size of the base 221 on the inner platform 213 corresponds to the size of the inner platform 213. The base 221 on the inner platform 213 also has a locking component 23 inside.

[0049] The outer platform 212 is equipped with 12 counterweight blocks 211, which are placed in a stack of three layers on the outer platform 212 and four layers in total. The inner platform 213 is equipped with 8 counterweight blocks 211, which are placed in a stack of two layers on the inner platform 213 and four layers in total. With 8 in the front and 12 in the back, there are a total of 20 counterweight blocks weighing 25kg each. This ensures the stability of the fence, reduces the stacking height of the counterweights, and balances the force on the diagonal bracing of the fence, enabling it to withstand gusts of wind up to level 9.

[0050] When in use, first place the uprights 11, the base rods 14 and the diagonal braces 15 in the designated positions, then use bolts to connect the enclosure 12 and the color steel plate 13, and then fix them.

[0051] Move the base 221 upwards so that the positioning pins 224 align with the positioning slots 212-1. Then lower the base 221, inserting the two positioning pins 224 into their corresponding positioning slots 212-1. Next, place the 12 counterweights 211 onto the lifting plate 223 in sequence. As the counterweights 211 are placed, the lifting plate 223 will gradually move downwards, simultaneously driving the pressing block 231 downwards. The inclined end face of the bottom of the pressing block 231 will first engage with the inclined surface 232-1 of the locking block 232, applying a pushing force to the locking block 232, causing it to move along the moving slot 224-1 towards the outside of the positioning pins 224 and engage with the locking slot 212-2. When the two engage, the base 221 cannot be separated from the outer platform 212. Then, the bolts... Connect the upper color steel plate 235 to multiple uprights 222. The uprights 222, base 221, and upper color steel plate 235 will form a complete rectangular frame. Multiple counterweights 211 are neatly placed inside. The frame organizes the stacking method of the counterweights 211, effectively controlling the stacking height of the counterweights while ensuring stability, avoiding excessive occupation of construction space, and adapting to the needs of complex construction sites and dense crowds in municipal engineering projects. Then, eight counterweights 211, together with the uprights 222, base 221, and upper color steel plate 235, are placed on the inner platform 213, with eight in the front and twelve in the back, for a total of 20 counterweights of 25kg each. This ensures the stability of the fence, reduces the stacking height of the counterweights, and balances the force on the diagonal bracing of the fence, enabling it to withstand gusts of wind up to level 9.

[0052] When the fence structure needs to be reused, first remove the upper color steel plate 235, then remove the counterweight 211 in sequence. The first elastic pad 225 resets the lifting plate 223, and the second elastic pad 234 resets the locking block 232. It is now completely inside the positioning post 224, which will not hinder the separation of the positioning post 224 and the positioning groove 212-1. After that, the base 221 can be separated from the outer platform 212 and the inner platform 213, and the fence 12 can be disassembled from the post 11 for reuse.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
