Description

Technical Field

[0001] The utility model relates to a prefabricated concrete pile column. Background Art

[0002] At present, the fence generally adopts the method of cast-in-place foundation + column + metal fence. The traditional foundation method is generally cast-in-place independent foundation, strip foundation or brick foundation; the column method is generally metal column, brick column or cast-in-place concrete column.

[0003] Objective disadvantages: The traditional wall foundation relies on footing to meet the vertical load and anti-overturning requirements of the upper structure, and the amount of foundation pit excavation, earthwork transportation, concrete and formwork used are all large. The metal columns on the wall are connected to the foundation with embedded parts and bolts. Due to the accuracy or error of on-site installation, the railings are prone to shaking on the top surface of the foundation. The labor cost of brick columns or cast-in-place concrete columns is high. Therefore, the traditional foundation method has more processes, the concrete curing time is long, the construction period is long, and the cost is high. Utility Model Content

[0004] The utility model aims to provide a prefabricated concrete pile column which has a more direct and effective force transmission path, does not require earthwork, saves on-site reinforcement work, and has a stronger ability to resist foundation deformation.

[0005] The purpose of the utility model is achieved in this way:

[0006] A prefabricated concrete pile column comprises a pile column body, wherein the pile column body comprises an above-ground part and an underground part, the above-ground part is provided with a line pipeline hole, and a side wall of the above-ground part is provided with a wall interface.

[0007] Improve the quality of components: This utility model greatly improves the quality of components through factory prefabrication. The construction quality has changed from relying on the skill level of on-site construction personnel to industrialized, standardized and controllable production in the factory assembly line. The use of customized steel mold products ensures that the steel bar ratio, pipeline pre-embedding, concrete vibration and component maintenance temperature and humidity are all completed under intelligent control. The dimensional error of each component is controlled at the millimeter level (no more than 3-5 mm), achieving a precision that is difficult to achieve with traditional construction methods.

[0008] Shorten the construction period: The utility model allows factory prefabrication and on-site construction to proceed simultaneously, significantly shortening the construction period and improving the overall benefits. The components produced in the factory are not affected by on-site weather and other factors, and can be carried out simultaneously with the construction of each stage. It has the advantages of fast construction speed, short engineering period and winter construction, which effectively speeds up the overall progress of the project.

[0009] Energy saving and environmental protection: By transferring a large number of traditional on-site operations to the factory, this utility model has greatly reduced noise, dust and construction waste on site, reduced safety hazards and accident risks on the construction site, and responded to the national energy saving and environmental protection requirements. The high degree of mechanization further improves the quality of the project and reduces safety hazards.

[0010] Improve construction accuracy and quality: This utility model improves the construction accuracy and quality of the fence through modular, standardized and integrated design, and extends the service life of the fence. Precise construction not only improves the functional quality of the fence, but also improves the quality of the entire project product.

[0011] Reduce earthwork and avoid dust pollution: The utility model does not need to excavate a large area of ​​foundation pit, and uses pile driving machinery to directly send the piles to the designed depth, avoiding the large amount of earthwork required for traditional foundation construction and reducing dust pollution.

[0012] Reducing on-site reinforcement and concrete operations: The utility model adopts factory-prefabricated piles and columns, which eliminates the need for on-site reinforcement processing and concrete pouring, reducing the workload and wet work volume at the construction site.

[0013] Strong ability to resist foundation deformation: The buried depth of the piles of the utility model has been accurately calculated, which can resist uneven settlement of the foundation, prevent foundation deformation and cracking of the upper wall, and has more advantages than traditional brick footing foundations or concrete foundations.

[0014] Adaptability to complex geological conditions: The pile design of the utility model is suitable for a variety of complex foundations, such as soft soil foundations, fill areas and collapsible sites. The depth of the pile into the soil is determined by calculation to avoid the influence of adverse geology, and the adaptability is stronger.

[0015] Short construction period and high comprehensive benefits: The utility model does not require foundation pit excavation and concrete curing. After the piles are pressed into the predetermined elevation, the next step of construction can be carried out. The construction efficiency is high, the construction period is shortened, and the comprehensive benefits are improved.

[0016] Strong durability: Factory-prefabricated components have high precision and stable mechanical properties. There is no rust problem that may occur in metal columns fixed with pre-embedded bolts or post-added expansion bolts, which significantly improves the durability of the components.

[0017] Vertical load distribution: When bearing vertical load, the utility model not only relies on the reaction force provided by the soil at the bottom of the foundation, but also utilizes the friction force provided by the soil on the side walls of the foundation to enhance the bearing capacity of the foundation.

[0018] Horizontal load balance: Under the action of horizontal load, the utility model balances the relevant bending moment through the constraint force of the soil around the pile column on the pile. Compared with the traditional foundation that needs to increase the footing size to ensure the overall stability of the wall, the force transmission method of the utility model is more direct and effective, thereby improving the stability of the structure.
