Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a pier structure and its construction method. Background Technology

[0002] In the field of building construction, the pile cap, as an important component of large structures such as bridges and high-rise buildings, primarily functions to bear and distribute the loads transmitted from the pier. Traditional pile cap construction methods often employ brick formwork technology, which involves erecting a brick formwork on top of the pile foundation and then pouring reinforced concrete onto this formwork. However, the brick formwork construction method has many drawbacks, such as a long construction period, long curing time, high labor input, and susceptibility to rainy season conditions, making it difficult to guarantee construction quality.

[0003] Furthermore, during the construction of brick formwork, improper operation by construction workers or material quality issues can easily lead to weak joints, causing safety hazards such as leakage during the use of the foundation. This not only affects the durability of the foundation but may also threaten the safety of the entire structure. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides:

[0018] Furthermore, a foundation pile is installed inside the clearance hole, the diameter of the clearance hole is D1, and the diameter of the foundation pile is D2, satisfying: D1-D2≥10cm.

[0019] Furthermore, the positioning component is provided with an installation component, the installation component includes a connector, the connector has a positioning groove, and the positioning component is disposed in the positioning groove.

[0020] This application also provides a method for constructing a pier cap structure, the method comprising:

[0041] In building construction, existing foundation structures are mostly constructed by first building a formwork with bricks, and then pouring reinforced concrete on the formwork. However, using bricks to build the formwork is inefficient, and construction is easily affected by the rainy season, making it difficult to guarantee the construction quality.

[0042] In this embodiment, the main body 100 of the foundation is integrally cast to form a modular structure. When in use, the cast-in-place main body 100 of the foundation can be hoisted to the installation position using hoisting equipment, thus eliminating the need to use bricks to form a template and greatly reducing construction time.

[0043] This application provides a pier structure, which includes a pier body 100, a positioning component 200, and a hoisting component 300.

[0044] Specifically, the main body 100 of the pier is cast in place, a plurality of positioning components 200 are disposed on the main body 100 of the pier, and a plurality of lifting components 300 are disposed on the main body 100 of the pier.

[0045] See Figure 1 As shown, in some embodiments, the main body 100 of the foundation is cast as a whole. When a foundation is needed at the construction site, a hoisting device is used to lift the main body 100 of the foundation through the hoisting component 300. Then, the positioning component 200 is used to position the main body 100 of the foundation and hoist it to the predetermined position to complete the installation of the main body 100 of the foundation. Compared with the existing method of using bricks to form a template, the method of hoisting to install the modularly formed main body 100 of the foundation to the predetermined position can greatly reduce the construction time and is less affected by the natural environment. Furthermore, the connection between the various parts of the integrally cast foundation 100 has no gaps, so there will be no leakage and the overall strength is greater, which meets the strength required for construction.

[0046] In one embodiment, the support body 100 has a through-hole 400. The support body 100 includes a base 110, a sidewall 120, and a pad 130. The through-hole 400 is formed on the base 110. The sidewall 120 is disposed on the outer periphery of the base 110. The pad 130 is disposed at the end of the sidewall 120 away from the base 110. The base 110, the sidewall 120, and the pad 130 are integrally formed and define a receiving cavity 140.

[0047] See Figure 1 and Figure 2As shown, the main body 100 of the foundation is mainly composed of a base 110, a side wall 120, and a pad 130. The side wall 120 is located on the outer periphery of the base 110. It can be understood that the base 110 is at the bottom, the pad 130 is located on the periphery of the base 110, and the pad 130 is at the top. Specifically, the base 110, the side wall 120, and the pad 130 are integrally cast using a matching mold. Since it is integrally cast, there will be no gaps between the base 110 and the side wall 120 and between the side wall 120 and the pad 130. In other words, there will be no leakage at the connection between the base 110 and the side wall 120 and between the side wall 120 and the pad 130, resulting in better quality of the main body 100 of the foundation.

[0048] In one embodiment, the accommodating cavity 140 allows the middle of the main body 100 of the support platform, which consists of the base 110, sidewalls 120, and padding layer 130, to be open, thereby reducing the overall weight and meeting design requirements, making the main body 100 of the support platform easier to handle during transportation or hoisting.

[0049] In one embodiment, to meet design requirements, the distance from the outer peripheral surface of the pad 130 to the outer peripheral surface of the sidewall 120 is L, satisfying: L≥10cm.

[0050] In one embodiment, a waterproof layer 500 is provided on the inner side of the accommodating cavity 140. By attaching a waterproof layer 500 to the inner wall of the accommodating cavity 140, the waterproof capability is further improved, and leakage is prevented.

[0051] Furthermore, the waterproof layer 500 can be a waterproof coating, such as a polyurethane waterproof coating applied to the inner wall of the accommodating cavity 140, or other waterproof materials can be applied. Alternatively, a waterproof membrane can be applied to the inner wall of the accommodating cavity 140 by means of adhesion, such as asphalt waterproof membrane or polymer modified waterproof membrane, which can be adhered to the inside of the accommodating cavity 140 to achieve the waterproof function.

[0052] To further improve waterproofing performance, the waterproofing layer 500 extends outward by at least 10cm at the edge, thereby enhancing waterproofing performance.

[0053] The hoisting component 300 includes a fixing component 310 that is fixedly connected to the main body 100 of the support platform, and the fixing component 310 is connected with a lifting nail 320.

[0054] See Figure 1 and Figure 2As shown, in order to enable the overall hoisting, transportation and movement of the main body 100 of the pier, multiple hoisting components 300 are provided on the main body 100 of the pier. Specifically, in this embodiment, there are four hoisting components 300, all of which are provided on the upper surface of the pad 130. The four hoisting components 300 are evenly spaced on the pad 130. By evenly arranging the four hoisting components 300, it is easier to keep the center of gravity of the main body 100 of the pier in the middle during hoisting, preventing the main body 100 of the pier from tilting during hoisting. The number of hoisting components 300 can also be other numbers, such as five, six, seven, eight, etc. In order to ensure the stability during hoisting, the number of hoisting components 300 should not be less than four.

[0055] Please continue reading. Figure 1 As shown, each lifting component 300 is connected to a sling 800, and each sling 800 is connected to the lifting device at the same position. In this embodiment, the four slings 800 form a quadrangular pyramid shape, and the slings 800 can be steel wire ropes.

[0056] In one embodiment, the lifting component 300 consists of a fixing component 310 and a lifting nail 320. The fixing component 310 is connected to the pad layer 130, and the lifting nail 320 is connected to the lifting cable 800. In order to ensure the bonding force between the fixing component 310 and the pad layer 130, the fixing component 310 can be pre-embedded in the pad layer 130 during the pouring process, thereby improving the bonding force between the fixing component 310 and the pad layer 130 and preventing the pad layer 130 from separating from the fixing component 310 during the lifting process, which could cause a construction accident.

[0057] It is understood that the lifting nail 320 mainly serves to connect with the sling 800. In this embodiment, the lifting nail 320 can be composed of a connecting rod and a connecting ring, and the connecting rod and the connecting ring are integrally formed. The connecting rod can be integrally or separately connected with the fixing member 310. If the connecting rod and the fixing member 310 are integrally formed, the fixing member 310, the connecting rod and the connecting ring can be integrally formed by casting or other methods. If the connecting rod and the fixing member 310 are separately connected, a threaded hole can be opened on the fixing member 310, and then an external thread can be provided on the outer surface of the end of the fixing member 310 facing the fixing member 310. That is, the connecting rod and the fixing member 310 are connected separately by threaded connection.

[0058] A foundation pile 600 is installed inside the clearance hole 400. The diameter of the clearance hole 400 is D1, and the diameter of the foundation pile 600 is D2, satisfying: D1-D2≥10cm.

[0059] Please continue reading. Figure 2As shown, when there is a foundation pile 600 at the location where the foundation is installed, a clearance hole 400 needs to be opened through the inner bottom wall of the accommodating cavity 140. In order to achieve clearance for the foundation pile 600, the diameter of the clearance hole 400 needs to be larger than the diameter of the foundation pile 600. In this embodiment, in order to make it easier for the foundation pile 600 to enter the clearance hole 400, the diameter of the clearance hole 400 is at least 10cm larger than the diameter of the foundation pile 600 to prevent the foundation pile 600 from colliding with the bottom of the base 110 during installation.

[0060] The positioning component 200 is provided with an installation component 700, the installation component 700 includes a connector 710, the connector 710 has a positioning groove 720, and the positioning component 200 is disposed in the positioning groove 720.

[0061] See Figure 2 and Figure 3 As shown, in order to ensure that the main body 100 of the support platform can be installed in the predetermined position, a plurality of evenly distributed positioning members 200 are provided at the bottom of the main body 100 of the support platform, and an installation member 700 adapted to the positioning member 200 is provided at the installation position. In this embodiment, the number of positioning members 200 and installation members 700 is four. Of course, other numbers are also possible. For example, the number of positioning members 200 and installation members 700 can be five, six, seven, eight, etc. The specific number is not limited here.

[0062] Specifically, installation components 700, which are compatible in number and position with the positioning components 200, are pre-embedded in the foundation pit where the main body 100 of the pier is placed, so that the positioning components 200 can be directly placed into the installation components 700 to complete the positioning when the main body 100 of the pier is installed.

[0063] Please continue reading. Figure 3 As shown, the mounting component 700 consists of a connector 710 and a positioning groove 720. The positioning groove 720 is adapted to the shape of the positioning component 200. In this embodiment, the connector 710 is "T" shaped, and both the positioning groove 720 and the positioning component 200 are "I" shaped. When in use, it is only necessary to align the positioning component 200 with the positioning groove 720 so that the positioning component 200 is inserted into the connector 710 to complete the positioning.

[0064] It should be noted that, in order to ensure that the overall strength of the mounting component 700 is not easily deformed, the mounting component 700 is made entirely of steel. Correspondingly, the positioning component 200 is also made of steel. The positioning component 200 is pre-embedded when the main body 100 of the foundation is poured, thereby ensuring the connection strength between the positioning component 200 and the main body 100 of the foundation.

[0065] See Figure 4As shown in the embodiments of this application, a method for constructing a pier cap structure is also provided. This method is used for the manufacture and installation of the pier cap structure, and the method includes:

[0066] S100: Mold making;

[0067] S200: Pour concrete according to the shape of the mold to form the main body of the foundation 100;

[0068] S300: Remove the formed support body 100 from the mold;

[0069] S400: The main body 100 of the pier is hoisted to the installation position by the hoisting equipment and the hoisting component 300, so that the positioning component 200 is placed in the installation component 700 at the installation position, and the foundation pile 600 at the installation position of the main body 100 of the pier passes through the clearance hole 400 into the main body 100 of the pier.

[0070] S500: Construction and installation completed.

[0071] In this embodiment, the mold drawings are first created based on the actual site conditions. Then, the mold is manufactured according to the drawings to determine the specifications and geometry of the main body 100, ensuring that the manufactured main body 100 meets the requirements. After the mold is manufactured, reinforced concrete can be poured according to the shape of the mold. After the pouring is completed, the mold can be removed to take out the main body 100. After the main body 100 is taken out, its shape and size are inspected. If the pouring location of the main body 100 is far from the construction site, hoisting equipment is used to hoist the main body 100 by combining the hoisting component 300 with the sling 800. The main body 100 can be hoisted onto the transport vehicle. To prevent the main body 100 from colliding, a placement frame can be set on the vehicle to support the main body 100. Specifically, the placement frame can be supported by multiple pads. To further ensure that the main body 100 is not bumped, the pads can be made of rubber.

[0072] After the main body 100 of the foundation is transported to the installation position, the main body 100 of the foundation is hoisted into the foundation pit again using hoisting equipment, so that the positioning component 200 is inserted into the installation component 700 for positioning, and the foundation pile 600 in the foundation pit is inserted into the avoidance hole 400. Specifically, after the main body 100 of the foundation is completely placed and installed in the foundation pit, it is necessary to pour concrete again in the gap between the avoidance hole 400 and the foundation pile 600 to prevent leakage between the avoidance hole 400 and the foundation pile 600.

[0073] In this embodiment, the foundation pit required for installation has been excavated before the main body 100 of the foundation is installed, and the foundation pit is ensured to be excavated to the position of the cushion layer 130.

[0074] In one embodiment, the lifting equipment can be a crane, tower crane, gantry crane, or other lifting equipment. In practice, the appropriate equipment can be selected based on the actual scenario or the weight and size of the pier body 100. No specific limitations are made here.

[0075] In this embodiment, after the mold is made, a release agent is applied to the inner wall of the mold. After the main body 100 of the support platform is removed from the mold, a waterproof layer 500 is installed on the inner wall of the main body 100 of the support platform, and the waterproof layer 500 extends at least 10cm at the edge of the main body 100 of the support platform.

[0076] The base body 100 is made easier to remove by applying a release agent to the inner wall of the mold, and the waterproofness of the base body 100 is improved by extending a waterproof layer 500 at least 10 cm to the edge of the base body 100.

[0077] After the main body 100 of the foundation is removed from the mold, it is cured at temperature T for time X, satisfying the following conditions: X≥28 days, 10℃≤T≤30℃.

[0078] In this embodiment, in order to ensure the strength of the foundation body 100, it is also necessary to cure the foundation body 100. Specifically, the curing temperature is between 10℃ and 30℃, for example, the curing temperature can be 10℃, 15℃, 20℃, 25℃, 30℃, etc. In this embodiment, the temperature can be set at 20℃. At this temperature, it can help the water reaction inside the concrete and promote the development of strength. The curing time can be 28 days, and the minimum curing time is not less than 14 days. The relative humidity used for curing is above 90%, so that the cement in the concrete can continue to hydrate and the strength of the concrete can continue to increase. If the humidity is insufficient, the water in the concrete will evaporate rapidly, which will hinder the cement hydration and thus affect the strength development of the concrete.
