[0002] In the field of construction engineering, the cap is an important part of large structures such as bridges and high-rise buildings. Its main function is to bear and distribute the load transmitted by the pier body. The traditional cap forming construction method often uses brick formwork technology, that is, building a template made of bricks on the top of the pile foundation, and then pouring reinforced concrete on this template. However, the brick formwork construction method has many defects, such as long construction period, long maintenance time, large labor input, and easy to be affected during the rainy season, making it difficult to ensure construction quality.

[0003] In addition, during the construction of the brick formwork, due to improper operation of the construction workers or material quality problems, the joints are prone to be loose, resulting in leakage and other safety hazards during the use of the foundation. This not only affects the durability of the foundation, but may also pose a threat to the safety of the entire structure. Summary of the invention

Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] In building construction, the existing foundation structure is mostly made of bricks to form a template, and then reinforced concrete is poured on the template. However, the efficiency of using bricks to build the template is low, and the construction is easily affected during the rainy season, making it difficult to ensure the construction quality.

[0042] In this embodiment, the base body 100 is cast in one piece to be modularized. When in use, the cast base body 100 only needs to be hoisted to the installation position using hoisting equipment, thereby eliminating the need to use bricks to form a template, greatly reducing the construction time.

[0043] The embodiment of the present application provides a support platform structure, which includes a support platform body 100, a positioning member 200 and a hanging member 300.

[0044] Specifically, the support body 100 is cast, a plurality of the positioning members 200 are disposed on the support body 100 , and a plurality of the hanging members 300 are disposed on the support body 100 .

[0045] See also Figure 1 As shown, in some embodiments, the pedestal body 100 is cast as a whole, and when a pedestal is needed at the construction site, the pedestal body 100 is lifted by a lifting device through a lifting member 300, and then the pedestal body 100 is positioned through a positioning member 200, and the pedestal body 100 is lifted to a predetermined position to complete the installation of the pedestal body 100. Compared with the existing method of forming a template with bricks, the pedestal body 100 that has been modularly formed is installed to a predetermined position by lifting. This can greatly reduce the construction time and is less affected by the natural environment. In addition, there are no gaps at the joints between the various parts of the pedestal body 100 that is cast as a whole, so there will be no leakage and the like, and the overall strength is greater, meeting the strength required for construction.

[0046] In one embodiment, the support body 100 is provided with an avoidance hole 400 passing through it, and the support body 100 includes a base 110, a side wall 120 and a cushion layer 130. The avoidance hole 400 is opened through the base 110, the side wall 120 is arranged on the outer peripheral side of the base 110, and the cushion layer 130 is arranged at the end of the side wall 120 away from the base 110. The base 110, the side wall 120 and the cushion layer 130 are integrally formed and define a accommodating cavity 140.

[0047] See also Figure 1 and Figure 2As shown, the base body 100 is mainly composed of a base 110, a side wall 120 and a cushion layer 130. The side wall 120 is located on the outer peripheral surface of the base 110, and the side wall 120 is located on the outer peripheral surface of the side wall 120. It can be understood that the base 110 is located at the bottom, the side wall 120 is located on the peripheral side of the base 110, and the cushion layer 130 is located at the top. Specifically, the base 110, the side wall 120 and the cushion layer 130 are integrally cast and formed by a matching mold. Since it is an integrally cast molded, there will be no corresponding gap between the connection between the base 110 and the side wall 120 and the connection between the side wall 120 and the cushion layer 130, that is to say, there will be no leakage from the connection between the base 110 and the side wall 120 and the connection between the side wall 120 and the cushion layer 130, so that the quality effect of the base body 100 is better.

[0048] In one embodiment, the accommodating cavity 140 is used to keep the middle of the platform body 100 composed of the base 110, the side wall 120 and the cushion layer 130 free of air, thereby reducing the overall weight and meeting the design requirements, so that the platform body 100 as a whole is easier to carry during transportation or hoisting.

[0049] In one embodiment, in order to meet design requirements, the distance L that the outer circumference of the cushion layer 130 exceeds the outer circumference of the side wall 120 satisfies: L ≥ 10 cm.

[0050] In one embodiment, a waterproof layer 500 is disposed on the inner side of the accommodating cavity 140 . By pasting a layer of waterproof layer 500 on the inner wall of the accommodating cavity 140 , the waterproof layer 500 is used to further improve the waterproof capability and prevent leakage.

[0051] Furthermore, the waterproof layer 500 can be a waterproof coating, for example, a polyurethane waterproof coating is applied to the inner wall of the accommodating cavity 140, and other waterproof materials can also be used for application. Furthermore, a waterproof membrane can be pasted on the inner wall of the accommodating cavity 140. For example, an asphalt waterproof membrane, a polymer modified waterproof membrane, etc. can be pasted to the inside of the accommodating cavity 140 to achieve a waterproof function.

[0052] In order to further improve the waterproof performance, the waterproof layer 500 is extended at least 10 cm outward at the edge position, thereby improving the waterproof performance.

[0053] The hanging member 300 includes a fixing member 310 fixedly connected to the support platform body 100 , and the fixing member 310 is connected to a hanging nail 320 .

[0054] See also Figure 1 and Figure 2As shown, in order to realize the overall lifting, transportation and movement of the platform body 100, a plurality of lifting components 300 are arranged on the platform body 100. Specifically, in the present embodiment, there are four lifting components 300, and they are all arranged on the upper surface of the cushion layer 130. The four lifting components 300 are evenly spaced on the cushion layer 130. The evenly spaced four lifting components 300 make it easier to locate the center of gravity of the platform body 100 in the middle during lifting, thereby preventing the platform body 100 from tilting during lifting. The number of lifting components 300 can also be other numbers, such as five, six, seven, eight, etc. In order to ensure stability during lifting, the number of lifting components 300 should be no less than four.

[0055] Please continue reading Figure 1 As shown, each lifting member 300 is connected to a sling 800 , and each sling 800 is connected to the lifting device at the same position. In this embodiment, 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 is composed of a fixing component 310 and a hanging nail 320. The fixing component 310 is connected to the cushion layer 130, and the hanging nail 320 is connected to the sling 800. In order to ensure the bonding force between the fixing component 310 and the cushion layer 130, the fixing component 310 can be embedded in the cushion layer 130 during pouring, thereby improving the bonding force between the fixing component 310 and the cushion layer 130 and preventing the cushion layer 130 and the fixing component 310 from separating during lifting, thereby preventing a construction accident.

[0057] It can be understood that the hanging nail 320 mainly serves to connect with the sling 800. In the present embodiment, the hanging 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 connected to the fixing part 310 in an integral or split manner. If the connecting rod and the fixing part 310 are integrally formed, the fixing part 310, the connecting rod and the connecting ring can be integrally formed by casting or other methods; if the connecting rod and the fixing part 310 are connected in a split manner, a threaded hole can be opened on the fixing part 310, and then an external thread is set on the outer surface of the end of the fixing part 310 facing the fixing part 310, that is, the connecting rod and the fixing part 310 are connected in a split manner.

[0058] A foundation pile 600 is disposed in the avoidance hole 400 , the diameter of the avoidance hole 400 is D1 , and the diameter of the foundation pile 600 is D2 , satisfying: D1 - D2 ≥ 10 cm.

[0059] Please continue reading Figure 2As shown, when there is a foundation pile 600 at the position where the bearing platform is installed, it is necessary to open an avoidance hole 400 through the inner bottom wall of the accommodating cavity 140, and in order to avoid the foundation pile 600, it is also necessary to make the diameter of the avoidance hole 400 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 avoidance hole 400, the diameter of the avoidance hole 400 is at least 10 cm 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 member 200 is provided with a mounting member 700 . The mounting member 700 includes a connecting member 710 . The connecting member 710 is provided with a positioning groove 720 . The positioning member 200 is disposed in the positioning groove 720 .

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

[0062] Specifically, mounting members 700 matching the number and position of the positioning members 200 are pre-buried in the foundation pit where the base body 100 is placed and installed, so that when the base body 100 is installed, the positioning members 200 can be directly placed in the mounting members 700 to complete the positioning.

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

[0064] It should be noted that in order to ensure the overall strength of the mounting member 700 and prevent it from being deformed, the mounting member 700 is made of steel as a whole. Correspondingly, the positioning member 200 is also made of steel. The positioning member 200 is embedded in the base body 100 when it is cast, thereby ensuring the connection strength between the positioning member 200 and the base body 100.

[0065] See also Figure 4As shown, the embodiment of the present application also provides a method for constructing a cap structure, which is used for manufacturing and installing the cap structure. The method for constructing a cap structure includes:

[0066] S100: making mold;

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

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

[0069] S400: hoisting the platform body 100 to the installation position through the hoisting member 300 by hoisting equipment, placing the positioning member 200 in the installation member 700 at the installation position, and penetrating the avoidance hole 400 through the foundation pile 600 at the installation position of the platform body 100 into the platform body 100;

[0070] S500: Construction and installation completed.

[0071] In this embodiment, a drawing of the mold is first drawn through the actual site, and then the mold is made according to the drawing, so as to determine the specifications and geometric shape of the pedestal body 100, so as to ensure that the manufactured pedestal body 100 meets the needs. After the mold is made, 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 pedestal body 100. After the pedestal body 100 is taken out, its shape, size, etc. are inspected. If the casting site of the pedestal body 100 is far from the construction site, the pedestal body 100 is lifted by a lifting equipment through the lifting piece 300 and the sling 800. The pedestal body 100 can be lifted onto the transfer vehicle. In order to prevent the pedestal body 100 from colliding, a placement frame can be set on the vehicle to support the pedestal body 100. Specifically, the placement frame can be supported by a plurality of pads. In order to further prevent the pedestal body 100 from being bumped, the pads can be made of rubber.

[0072] After the pedestal body 100 is transported to the installation location, the pedestal body 100 is hoisted into the foundation pit again using hoisting equipment, so that the positioning member 200 is inserted into the installation member 700 for positioning, and the foundation pile 600 in the foundation pit is inserted into the avoidance hole 400. Specifically, after the pedestal body 100 is completely placed and installed in the foundation pit, it is necessary to cast concrete for a second time 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, before the base body 100 is installed, the foundation pit required for the installation has been excavated and formed, and the foundation pit is ensured to be excavated to the position of the cushion layer 130.

[0074] In one embodiment, the lifting equipment may be a crane, a tower crane, a gantry crane or other lifting equipment. In practice, it may be selected and used according to the actual scene or the weight of the supporting platform body 100, and no specific limitation is 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 base body 100 is removed from the mold, a waterproof layer 500 is installed on the inner wall of the base body 100, and the waterproof layer 500 extends at least 10 cm at the edge of the base body 100.

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

[0077] After the support body 100 is released from the mold, it is cured at a temperature T for a time of X, satisfying: X ≥ 28 days, 10°C ≤ T ≤ 30°C.

[0078] In this embodiment, in order to ensure the strength of the base body 100, the base body 100 also needs to be cured. Specifically, the curing temperature is between 10°C and 30°C. For example, the curing temperature can be 10°C, 15°C, 20°C, 25°C, 30°C and other temperatures. In this embodiment, the temperature can be set at 20°C. At this temperature, it can help the splash 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 be continuously hydrated and the strength of the concrete can be continuously increased. If the humidity is insufficient, the water in the concrete will evaporate rapidly, resulting in the obstruction of cement hydration, which in turn affects the strength development of the concrete.
