Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, and particularly relates to an assembled hole cover plate for PHC pipe piles. Background Art

[0002] At the construction site, after the construction of PHC pipe piles is completed, a large number of holes will be left. During the construction operation, sundries such as soil will fall into the pile holes, and there is a safety risk that personnel's legs and feet will fall into them when people are constructing nearby.

[0003] The traditional solution is to use a template to make a small cover plate to cover the pile hole, but it is not firm. Moreover, large construction machinery often travels at the construction site, which will damage the cover plate and often cause it to shift, resulting in poor covering effect of the pile hole and unable to cover it for a long time. In addition, the small cover plate cannot be recycled later, which will waste the template and increase the material cost of the project. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above defects and propose an adjustable pile hole covering device, so as to solve the problem of covering the pile holes after the construction of PHC pipe piles in the project.

[0005] In order to achieve the above purpose, the utility model is realized as follows:

[0006] An assembled hole cover plate for PHC pipe piles includes a cover plate body and also includes positioning members. The positioning members are evenly distributed in a circumferential form on the bottom surface of the cover plate body. The cover plate body is inserted into the end hole of the PHC pipe pile through the positioning members and covers and seals the end hole.

[0007] For the assembled hole cover plate for PHC pipe piles, holes are opened on the cover plate body, and the holes are distributed on a circumferential track and are used for the positioning members to pass through.

[0008] For the assembled hole cover plate for PHC pipe piles, the positioning members are evenly distributed in a circumferential form on the bottom surface of the cover plate body. The diameter of the circle is equal to the inner wall diameter of the PHC pipe pile. The positioning members are cylinders, and the side wall contour lines thereof are arranged tangent to the diameter of the circle.

[0009] For the assembled hole cover plate for PHC pipe piles, multiple groups of positioning members are arranged at the bottom of the cover plate body according to the pipe diameters of different PHC pipe piles.

[0010] For the assembled hole cover plate for PHC pipe piles, every three positioning members form a group and are evenly spaced in a circumferential form on the bottom surface of the cover plate body.

[0011] For the assembled hole cover plate for PHC pipe piles, every three positioning members form a group and are distributed in an equilateral triangle state with the center point at the bottom of the cover plate body as the origin.

[0012] The utility model effectively solves the problem that it is impossible to quickly and effectively cover the PHC piles after construction. For the problem that the wall thickness of the piles is different, resulting in different sizes of the pile holes, it is used according to local conditions through the adjusting holes at different positions on the cover plate body, and has strong applicability.

[0013] The positioning rods used in the utility model can be made of waste steel bar heads in the steel bar processing yard, which can realize the reuse of waste. The cover plate and the fixing rods are both made of ironware, are not easy to wear, and can be recycled many times, with good economic benefits. Description of the Drawings

[0015] Figure 2 It is a schematic structural diagram of the positioning rod in Embodiment 1. Detailed Implementation Modes

[0016] Next, the technical solutions of the embodiments of the present application will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present application.

[0017] Taking the most commonly used PHC500-100 / 125 piles in construction engineering as an example for illustration: PHC500-100 is a pipe pile with a diameter of 500 and a wall thickness of 100, and the diameter of the pile hole is 300. The PHC500-125 pile is a pipe pile with a diameter of 500 and a wall thickness of 125, and the diameter of the pile hole is 250.

[0018] A pile hole covering device for PHC pipe piles is used to cover its end holes. The pile hole covering device for PHC pipe piles is composed of a steel disc 1 with six adjusting holes and three T-shaped fixing rods 2; each adjusting hole is evenly arranged at an interval of 60°. The steel disc is made of a steel disc with a certain thickness and diameter. There are six φ16 round holes on it. The hole positions are within the edges of φ300 and φ250 and correspond to PHC500-100 and PHC500-125 respectively. When in use, according to the different sizes of the pile holes, the three fixing rods are inserted into the corresponding adjusting holes, so as to realize the function of fixing the cover plate.

[0019] Through the above embodiments, it can be seen that the utility model proposes an end hole covering device for assembled PHC pipe piles composed of an assembled cover plate and positioning rods. This covering device provides a device for PHC pipe piles that is convenient for disassembly and assembly and can effectively cover the end holes through a plug-in connection method.

[0020] This device solves the problem that it is impossible to quickly and effectively cover the PHC piles after construction. For the problem that the wall thickness of the piles is different, resulting in different sizes of the pile holes, it is used according to local conditions through the adjustment holes at different positions on the cover body, with strong applicability.

[0021] The above are only the embodiments provided by this application and are not used to limit this application. Although this application has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
