Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a building pile for building engineering. Background Technology
[0002] Building piles in construction engineering are long, high-strength structural members that penetrate deep into the ground. Their main function is to transfer the load of the superstructure to deeper soil or rock layers with stronger bearing capacity, thereby ensuring the stability of the building, controlling settlement, and preventing collapse.
[0003] The existing construction method for engineering piles generally involves first drilling the pile hole, then placing the engineering pile cylinder into the pile hole, and finally pouring concrete into the pile hole to form the pile. The existing patent (publication number: CN221030097U) discloses an engineering construction pile. This utility model, through the setting of connecting components, can easily and quickly connect and disassemble the connecting pile and the construction pile, making it very convenient to use. At the same time, the setting of plug-in components can insert the plug-in rod outward afterward. Therefore, after concrete is poured into the pile hole, it can increase the stability of the construction pile, increase the horizontal bearing capacity, and reduce its subsequent settlement.
[0004] To address the aforementioned issues, existing patents offer solutions. However, some existing construction piles that require hammering to insert into the ground lack a buffer structure at the contact point with the pile driver hammer. Repeated hammering can easily damage the piles. In particular, once the concrete piles are inserted into the ground, they are not easily protected against corrosion and are prone to carbonization on the surface due to the wet-dry cycle of underground soil and freeze-thaw cycles, affecting the strength and service life of the concrete piles.
[0005] Therefore, a type of building pile for construction engineering is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a construction pile for building engineering, which can solve the problem that some existing construction piles that need to be hammered into the ground do not have a buffer structure at the contact part with the pile driver hammer. Repeated hammering can easily damage the construction pile. In particular, after the concrete construction pile is inserted into the ground, it is not easy to obtain anti-corrosion protection. It is easy for the surface of the concrete construction pile to carbonize due to the dry and wet cycle of underground soil and freeze-thaw damage, which affects the strength and service life of the concrete construction pile.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a building pile for construction engineering, comprising a concrete building pile body, wherein a buffer mechanism is provided at the top of the concrete building pile body, a protective sleeve is provided on the surface of the concrete building pile body, and a protective layer is provided on the surface of the protective sleeve. The buffer mechanism includes a modified polyurethane elastomer buffer pad, a connecting plate, and a connecting sleeve. The connecting sleeve is fitted onto the surface of the concrete building pile. The bottom of the connecting plate contacts the top of the connecting sleeve. The bottom of the modified polyurethane elastomer buffer pad is fixedly connected to the top of the connecting plate.
[0008] Preferably, the protective layer includes a base layer, an adhesive layer, and an anti-corrosion layer. The base layer is made of epoxy powder and is electrostatically sprayed onto the surface of the protective sleeve and cured at high temperature to form a dense structure.
[0009] Preferably, the adhesive layer is made of vinyl copolymer adhesive, and the adhesive layer is uniformly coated on the surface of the base layer.
[0010] Preferably, the anti-corrosion layer is made of polyethylene coating, and the anti-corrosion layer is uniformly sprayed on the surface of the adhesive layer.
[0011] Preferably, the connecting sleeve has four screws internally threaded, and the side of the screws closest to the concrete pile body is in close contact with the surface of the concrete pile body.
[0012] Preferably, four limiting plates are fixedly connected to the surface of the connecting plate, and limiting pins are movably inserted into the interior of the limiting plates. The interior of the connecting sleeve is provided with limiting holes that cooperate with the limiting pins, and the limiting pins extend into the interior of the limiting holes.
[0013] Preferably, a strong magnet is fixedly connected to the surface of the limiting pin, and the surface of the strong magnet is magnetically attracted to the surface of the limiting plate. Two lifting rings are symmetrically fixedly connected to the surface of the connecting sleeve.
[0014] Preferably, the protective sleeve is bonded to the concrete pile body at the connection point using neutral single-component silicone weather-resistant sealant, and the protective sleeve is made of high-density polyethylene.
[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application solves the problem of existing building piles being easily damaged by hammering without buffering by setting up a buffer mechanism. The buffer mechanism is fitted onto the top of the concrete building pile through a connecting sleeve and is fixed by friction with four screws to prevent displacement. The connecting plate is positioned by the cooperation of the limiting plate, the limiting pin and the limiting hole of the connecting sleeve. The strong magnet of the limiting pin enhances stability and facilitates the replacement of the modified polyurethane elastomer buffer pad. When hammering, the modified polyurethane elastomer buffer pad deforms and absorbs energy, and the force is transmitted to the pile body through the connecting plate and the connecting sleeve, which disperses the hammering force and reduces damage. The lifting ring facilitates lifting and transportation. 2. This application addresses the issue of leakage by setting up a protective layer. The protective sleeve is made of high-density polyethylene and is bonded to the pile body with neutral single-component silicone weather-resistant sealant. The protective layer consists of an epoxy powder primer, a vinyl copolymer adhesive layer, and a polyethylene coating anti-corrosion layer from the inside out. These three layers work together to protect the concrete pile body from friction damage during insertion and prevent underground media erosion, thus solving the problems of insufficient anti-corrosion structure and easy carbonization of the underground part of existing concrete piles.

Detailed Implementation
[0018] 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.
[0019] Please see Figure 1-5 The present invention provides the following technical solution: A type of building pile for construction engineering includes a concrete building pile body 1, a buffer mechanism 3 is provided on the top of the concrete building pile body 1, a protective sleeve 2 is provided on the surface of the concrete building pile body 1, and a protective layer 9 is provided on the surface of the protective sleeve 2. The buffer mechanism 3 includes a modified polyurethane elastomer buffer pad 301, a connecting plate 302, and a connecting sleeve 303. The connecting sleeve 303 is fitted onto the surface of the concrete building pile 1. The bottom of the connecting plate 302 contacts the top of the connecting sleeve 303. The bottom of the modified polyurethane elastomer buffer pad 301 is fixedly connected to the top of the connecting plate 302.
[0020] In this embodiment: First, the connecting sleeve 303 of the buffer mechanism 3 is placed on top of the concrete pile 1. The four screws 5 inside the connecting sleeve 303 are tightened to fix the connecting sleeve 303 by friction to prevent displacement. Then, the connecting plate 302 is connected to the connecting sleeve 303. The limiting plate 10, the limiting pin 8 and the limiting hole 6 of the connecting sleeve 303 are used for positioning. The strong magnet 7 of the limiting pin 8 enhances stability and facilitates the replacement of the modified polyurethane elastomer buffer pad 301. During hammering, the buffer pad deforms and absorbs energy, which is transmitted to the concrete pile 1 through the connecting plate 302 and the connecting sleeve 303, dispersing the hammering force of the pile driver and reducing damage to the concrete pile 1. The lifting ring 4 facilitates lifting. Before the concrete pile 1 is inserted into the ground, a high-density polyethylene protective sleeve is placed. Two protective sleeves are applied to the surface of the concrete pile body 1, and then bonded with neutral single-component silicone weather-resistant sealant to prevent leakage. The surface of the protective sleeve 2 is sequentially coated with an epoxy powder primer 901, a vinyl copolymer adhesive layer 902, and a polyethylene coating anti-corrosion layer 903. The three layers work together to prevent corrosion and wear, protect the concrete pile body 1 and extend its service life. This solves the problem that some existing construction piles that need to be hammered into the ground do not have a buffer structure in the contact part with the pile driver hammer. Repeated hammering can easily damage the construction pile. In particular, after the concrete construction pile is inserted into the ground, it is not convenient to obtain anti-corrosion protection. It is easy for the surface of the concrete construction pile to carbonize due to the dry and wet cycle of underground soil and freeze-thaw damage, which affects the strength and service life of the concrete construction pile.
[0021] Specifically, such as Figure 5 As shown, the protective layer 9 includes a base layer 901, an adhesive layer 902, and an anti-corrosion layer 903. The base layer 901 is made of epoxy powder. The base layer 901 is electrostatically sprayed onto the surface of the protective sleeve 2 and cured at high temperature to form a dense structure.
[0022] Specifically, such as Figure 5 As shown, the adhesive layer 902 is made of vinyl copolymer adhesive, and the adhesive layer 902 is uniformly coated on the surface of the base layer 901.
[0023] Specifically, such as Figure 5 As shown, the anti-corrosion layer 903 is made of polyethylene coating, and the anti-corrosion layer 903 is evenly sprayed on the surface of the adhesive layer 902.
[0024] In this embodiment: the base layer 901 is formed by electrostatic spraying and high-temperature curing of epoxy powder to form a dense structure, which improves the adhesion to the protective sleeve 2 and initially blocks corrosion. The adhesive layer 902 is made of vinyl copolymer adhesive, which achieves a stable connection between the base layer 901 and the anti-corrosion layer 903 through chemical and physical action. The anti-corrosion layer 903 is sprayed with polyethylene coating to enhance the overall chemical corrosion resistance, wear resistance and weather resistance. The three layers work together to greatly improve the protective ability of the protective sleeve 2 to protect the concrete building pile 1.
[0025] Specifically, such as Figure 1 and Figure 2 As shown, the internal thread of the connecting sleeve 303 is connected to four screws 5, and the side of the screws 5 closest to the concrete pile 1 is in close contact with the surface of the concrete pile 1.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, four limiting plates 10 are fixedly connected to the surface of the connecting plate 302. Limiting pins 8 are movably inserted into the inside of the limiting plate 10. The connecting sleeve 303 has a limiting hole 6 that cooperates with the limiting pin 8. The limiting pin 8 extends into the inside of the limiting hole 6.
[0027] In this embodiment: the connecting sleeve 303 is in close contact with the concrete building pile 1 through four screws 5, and is firmly fixed by friction to prevent displacement during hammering. The limiting plate 10 and limiting pin 8 of the connecting plate 302 cooperate with the limiting hole 6 of the connecting sleeve 303 to achieve precise positioning and ensure the stability of the connection of the buffer mechanism 3 components.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, a strong magnet 7 is fixedly connected to the surface of the limiting pin 8, and the surface of the strong magnet 7 is magnetically attracted to the surface of the limiting plate 10. Two lifting rings 4 are symmetrically fixedly connected to the surface of the connecting sleeve 303.
[0029] Specifically, such as Figure 1 and Figure 4 As shown, the protective sleeve 2 is bonded to the concrete pile 1 at the connection point using neutral single-component silicone weather-resistant sealant. The protective sleeve 2 is made of high-density polyethylene.
[0030] In this embodiment: the strong magnet 7 of the limiting pin 8 is magnetically attracted to the limiting plate 10, which further prevents the limiting pin 8 from falling off during hammering vibration and facilitates the replacement of the buffer pad. The two lifting rings 4 facilitate hoisting operations. The protective sleeve 2 is made of high-density polyethylene and is bonded to the concrete building pile 1 with neutral single-component silicone weather-resistant sealant to ensure no gaps, effectively blocking soil and groundwater infiltration and improving the anti-corrosion effect.
[0031] Working principle: First, the buffer mechanism 3 at the top of the concrete pile 1 buffers the impact force of the pile driver hammer. The connecting sleeve 303 in the buffer mechanism 3 is first fitted onto the top surface of the concrete pile 1. Then, four screws 5 connected internally to the connecting sleeve 303 are tightened towards the concrete pile 1, ensuring close contact between the side of the screws 5 closest to the concrete pile 1 and the surface of the concrete pile 1. This frictional force secures the connecting sleeve 303 firmly to the top of the concrete pile 1, preventing the buffer mechanism 3 from shifting during hammering. Next, a connecting plate 302 is placed on top of the connecting sleeve 303, with the bottom of the connecting plate 302 contacting the top of the connecting sleeve 303. Simultaneously, the connecting... Four limiting plates 10 are fixed to the surface of plate 302. Limiting pins 8 are movably inserted into the limiting plates 10, extending into the limiting holes 6 inside the connecting sleeve 303. The cooperation between the limiting pins 8 and the limiting holes 6 achieves initial positioning of the connecting plate 302 and the connecting sleeve 303. Furthermore, the strong magnet 7 fixed to the surface of the limiting pin 8 magnetically attracts the surface of the limiting plate 10, further enhancing the stability of the limiting pin 8 and preventing it from falling off during hammering vibration. This also facilitates the replacement of the easily worn modified polyurethane elastomer buffer pad 301. Finally, relying on the modified polyurethane elastomer buffer pad 301 fixedly connected to the top of the connecting plate 302, when the pile driver hammer falls and strikes, the modified polyurethane elastomer buffer pad 301 first contacts the hammer head and... Elastic deformation occurs, converting part of the hammer's impact kinetic energy into its own elastic potential energy. This buffered force is then transferred to the connecting sleeve 303 via the connecting plate 302, and finally to the concrete pile 1. This effectively disperses the hammering force, preventing it from concentrating directly on the top of the concrete pile 1, significantly reducing damage caused by hammering. The lifting ring 4 fixed to the surface of the connecting sleeve 303 facilitates the lifting of the connecting sleeve 303 and the modified polyurethane elastomer buffer pad 301. Before the concrete pile 1 is inserted into the ground, a high-density polyethylene protective sleeve 2 is placed on the surface of the concrete pile 1, and the connection between the protective sleeve 2 and the concrete pile 1 is bonded with neutral single-component silicone weather-resistant sealant to ensure protection. There is no gap between the protective sleeve 2 and the concrete pile 1, preventing soil or groundwater from seeping in through the gaps. A protective layer 9 is applied to the surface of the protective sleeve 2. The base layer 901 of the protective layer 9 is made of epoxy powder, which is uniformly coated onto the surface of the protective sleeve 2 via electrostatic spraying and then cured at high temperature to form a dense structure. This dense base layer 901 adheres tightly to the surface of the protective sleeve 2, providing a good adhesion base for subsequent coatings and initially blocking corrosive media from contacting the protective sleeve 2. Next, an adhesive layer 902 made of vinyl copolymer binder is uniformly coated onto the surface of the base layer 901. Because the polar functional groups of the vinyl copolymer binder can react with the epoxy groups of the epoxy powder in the base layer 901, a strong chemical bond is formed.The non-polar ethylene portion can form good affinity with the subsequently coated anti-corrosion layer 903, thus achieving a stable connection between the base layer 901 and the anti-corrosion layer 903. Finally, an anti-corrosion layer 903 made of polyethylene coating is uniformly sprayed onto the surface of the adhesive layer 902. The anti-corrosion layer 903 formed by the polyethylene coating has excellent chemical corrosion resistance, wear resistance, and weather resistance, effectively blocking the erosion of the protective sleeve 2 and the concrete pile 1 by acidic and alkaline substances, groundwater, and microorganisms in the underground soil. Especially when the concrete pile 1 is inserted into the ground, the protective sleeve 2 can prevent the surface of the concrete pile 1 from peeling or breaking due to friction with the soil. The protective layer 9 further enhances the anti-corrosion and wear resistance of the protective sleeve 2, together providing a protective layer for the concrete pile 1 inserted into the ground. The concrete pile body 1 provides comprehensive protection, extending its service life. It solves the problem that some existing construction piles, which require hammering to insert into the ground, lack a buffer structure at the contact point with the pile driver hammer. Repeated hammering can easily damage the pile, especially after it's inserted into the ground, where corrosion protection is inconvenient. The pile surface is susceptible to carbonization due to underground soil cycles and freeze-thaw cycles, affecting its strength and service life. It should be noted that both the concrete pile body 1 and the pile driver are existing, published, and mature technologies. Any content not described in detail in this specification is prior art known to those skilled in the art, and its basic mechanisms will not be elaborated here.
[0032] The above are merely preferred embodiments of the present utility model and are 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.
