Description

Technical Field

[0001] The utility model relates to the technical field of pipe piles, in particular to a corrosion-resistant pipe pile cage. Background Art

[0002] Pile cages play a key role in reinforcing building piles. They are made of welded steel bars and are used to improve the bending and shear resistance of piles, increase the bearing capacity and anti-settlement capacity of the foundation, and ensure construction quality and building stability. They are especially effective in places with poor geological conditions such as soft soil and swamps, and are an indispensable reinforcement material in building pile foundation projects.

[0003] During the use of pipe pile cages used in existing buildings, due to the limited surface area of contact between the pipe pile cage and the concrete, the concrete is easily separated from the steel bars on the cage after being subjected to vibration or external pressure. At the same time, due to the characteristics of the materials used in the pipe pile cage, it is easy to rust, affecting the bending and shear resistance of the internal pipe piles. Therefore, a corrosion-resistant pipe pile cage is proposed. Utility Model Content

A large number of branches can be formed on the surface of the pipe pile cage, which can better wrap the concrete in the later stage and have a better integration effect with the dried concrete, so that the bonding strength between the concrete and the pipe pile cage after contact is better, which can reduce the corrosion time of the pipe pile cage and increase the service life of the pipe pile.

[0005] The technical solution adopted by the utility model to solve its technical problems is a corrosion-resistant pipe pile cage, comprising a pipe pile cage, wherein the pipe pile cage is composed of straight bars, spiral bars and tied bars, the straight bars are arranged in a ring with equal distances, the spiral bars are wound around the outer periphery of the straight bars arranged in a ring, and the spiral bars are welded to the straight bars.

[0006] The tie bars are buckled at the intersection of the straight bars and the spiral bars, and the two ends of the tie bars are spread out to form tentacles.

[0007] By adopting the above technical solution, through the components composed of straight bars, spiral bars and tie bars, a pipe pile cage structure with long service life, good stability and connection with the concrete structure wall is provided for construction construction. By setting the tie bars on the pipe pile cage, a large number of branches are formed on the surface of the pipe pile cage, so as to better wrap the concrete in the later stage and achieve a better integration effect with the dried concrete.

[0008] Specifically, the straight ribs, spiral ribs and tied ribs are made of the same material, which includes a carbon steel layer, and the surface of the carbon steel layer is pickled to form a concave hole layer.

[0009] By adopting the above technical solution and setting up the concave hole layer, the surface area of the straight bars, spiral bars and tied bars can be increased. After the concrete is dried, the notches in the concave hole layer can better lock the concrete, so that the bonding strength between the concrete and the pipe pile cage after contact is better.

[0010] Specifically, a hot-dip galvanized layer is provided on the surface of the concave hole layer.

[0011] By adopting the above technical solution and providing a hot-dip galvanized layer, an anti-corrosion layer can be formed on the surface of the straight bars, spiral bars and tied bars, which can greatly reduce the corrosion time of the pipe pile cage and increase the service life of the pipe pile.

[0012] Specifically, the number of straight bars is 6-12.

[0013] By adopting the above technical solution, it is more practical to select a corresponding number of straight bars according to different design requirements.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, the corrosion-resistant pipe pile cage described in the present invention includes a pipe pile cage 1, which is composed of straight bars 11, spiral bars 12 and tie bars 13. The straight bars 11 are arranged in a ring with equal distances, and the spiral bars 12 are wound around the outer periphery of the straight bars 11 arranged in a ring. The spiral bars 12 are welded to the straight bars 11.

[0023] The present invention further includes that the tie ribs 13 are buckled at the intersection of the straight ribs 11 and the spiral ribs 12 , and both ends of the tie ribs 13 are spread out to form antennae 131 .

[0024] During use, the straight bars 11, spiral bars 12, and tie bars 13 provide a long-lasting, stable, and securely connected pile cage structure for construction. These bars form numerous branches on the surface of the pile cage 1, effectively entrapping concrete and integrating it with the cured concrete. This improves the bond between the concrete and the pile cage 1, reduces corrosion time, and increases the service life of the piles. The number of straight bars 11 can range from 6 to 12, depending on requirements.

[0025] The present invention also includes that the straight ribs 11 , the spiral ribs 12 and the tied ribs 13 are made of the same material, and all include a carbon steel layer 101 , and a concave hole layer 102 is formed on the surface of the carbon steel layer 101 by pickling.

[0026] During use, the surface area of the straight bars 11, spiral bars 12 and tie bars 13 can be increased by utilizing the setting of the concave hole layer 102. After the concrete dries, the notches in the concave hole layer 102 can better lock the concrete, so that the bonding strength between the concrete and the pile cage 1 after contact is better.

[0027] The present invention further comprises that a hot-dip galvanized layer 103 is provided on the surface of the recessed hole layer 102 .

[0028] During use, based on the setting of the hot-dip galvanized layer 103, an anti-corrosion layer can be formed on the surface of the straight reinforcement 11, the spiral reinforcement 12 and the tied reinforcement 13, which can greatly reduce the corrosion time of the pipe pile cage 1 and increase the service life of the pipe pile.

[0029] When the utility model is in use, the burr effect on the surface of the pile cage 1 is improved by fastening the reinforcement bars 13, which makes it easier to cover the concrete, so that the concrete is better wrapped on the pile cage 1, and the integration effect between the concrete and the pile cage 1 after drying is higher. By setting the concave hole layer 102, the surface area of the straight reinforcement 11, the spiral reinforcement 12 and the reinforcement bars 13 can be increased. After the concrete is dried, the notches in the concave hole layer 102 can better buckle the concrete, so that the bonding force after the concrete and the pile cage 1 are in contact is better. By setting the hot-dip galvanized layer 103, an anti-corrosion layer can be formed on the surface of the straight reinforcement 11, the spiral reinforcement 12 and the reinforcement bars 13, which can greatly reduce the corrosion time of the pile cage 1 and increase the service life of the piles.
