It mainly supplements the compressive but not shearing properties of the pile foundation concrete. The compressive strength of the concrete is high but the tensile strength is very low. It restrains the pile body concrete so that it can withstand a certain axial tension. When constructing bridges, culverts or high-rise buildings, pile foundation construction is carried out in accordance with design requirements. The pile foundation construction methods include impact drilling, rotary drilling, etc., and the hole depth meets the design requirements. Then the steel cage is lowered into the pile hole, and then the conduit is inserted for concrete pouring. At present, the positioning of the steel cage is a very important link in the installation and construction of pile foundation steel bars. However, in actual construction, it is difficult for workers to accurately position the steel cage to the center of the circle.

[0017] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] The following is combined with Figure 1-3 The present invention is described in further detail.

[0019] The embodiment of the present invention discloses a pile foundation reinforcement cage positioning device. Figure 1-3The pile foundation steel cage positioning device includes a scale 1 and a fixed leg 2 which are horizontally arranged above the hole. The scale 1 is provided with two and the two scales 1 are arranged perpendicular to each other. The intersection of the two scales 1 is located at the center point of the hole. The fixed legs 2 are respectively arranged at both ends of the two scales 1 to fix the two scales 1 above the hole. A scale 3 is slidably arranged on the scale 1. The scale 3 is arranged perpendicular to the scale 1 and is used to lean against the outside of the stirrup of the steel cage. When in use, the steel cage is lowered into the hole. According to The diameter of the hole is determined by fixing the scale 1 above the hole through the fixed legs 2, and the intersection of the two scales 1 is located at the center of the hole. The lifting equipment is controlled to move the steel cage according to the position of the scale 3. The position of the scale 3 is adjusted during the movement of the steel cage so that the scale values ​​of the scale 3 on the scale 1 are the same and the outer side of the stirrups on the steel cage touches the scale 3, making the installation and positioning of the steel cage more accurate and faster, and the error meets the requirements of the specifications. The workers can perform visual operations when installing the steel cage, which increases construction efficiency and improves construction quality.

[0020] In this embodiment, a slide groove 11 is provided on the scale 1 along its length direction, and the scale 3 is slidably disposed in the slide groove 11 , so that the scale 3 can move along the slide groove 11 on the scale 1 .

[0021] In this embodiment, the ruler 3 is provided with an adhesive portion for sticking and fixing to the stirrups of the steel cage on the side facing the steel cage. The adhesive portion can be a double-sided tape, nail-free adhesive or other sticky items. The ruler 3 can be removed from the stirrups after use. When in use, the ruler 3 is moved to move the ruler 3 to the steel cage so that the adhesive portion is close to the outside of the stirrups of the steel cage. The ruler 3 is stuck to the stirrups through the adhesive portion. The lifting equipment is controlled according to the position of the ruler 3 to control the movement of the steel cage forward, backward, left and right. During the movement of the steel cage, the ruler 3 is driven to move until the ruler 3 stops after the scale values ​​on the scale ruler 1 are the same. After use, the ruler 3 is removed from the stirrups with force.

[0022] In this embodiment, the fixed leg 2 includes an insertion rod 21 fixed to the ground and an adjustment portion 22 arranged on the insertion rod 21 and connected to the end of the scale 1 for adjusting the height of the scale 1. The insertion rod 21 is inserted into the ground and fixed according to the size of the hole. Since the ground is not completely flat, the two ends of the scale 1 are adjusted by adjusting the adjustment portion 22, and the scale 1 is adjusted to a horizontal state with the use of a level.

[0023] In this embodiment, the adjusting portion 22 includes a connecting tube 221 connected to the top of the insertion rod 21 and a connecting rod 222 connected to the end of the scale 1. The insertion rod 21 and the connecting tube 221 are rotatably connected. The connecting rod 222 is inserted into the connecting tube 221 and is threadedly connected with the connecting tube 221. When adjusting the scale 1, the connecting tube 221 can be rotated to move the connecting rod 222 up and down, so that the heights of the two ends of the scale 1 can be adjusted, and the adjustment operation is simpler and more convenient.

[0024] In this embodiment, a baffle 23 is provided on the insertion rod 21. After the insertion rod 21 is inserted into the ground, the baffle 23 contacts the ground. The baffle 23 can limit the depth of the insertion of the insertion rod 21 into the ground, thereby limiting the insertion of the insertion rod 21.

[0025] In this embodiment, the fixed leg 2 is provided with a mounting rod 24 for mounting the scale 1 at the top end of the connecting rod 222, and mounting holes 12 for the mounting rod 24 to pass through are provided at both ends of the scale 1. The mounting rod 24 is provided with a locking nut 25 for pressing and fixing the scale 1, so as to facilitate the installation and disassembly of the scale 1.

[0026] In this embodiment, a butt joint groove 13 that interlocks with each other is provided in the middle position of the two scales 1. After one scale 1 is installed, the other scale 1 is passed through between the lifting ropes of the steel cage, and the butt joint grooves 13 on the two scales 1 are aligned and buckled. That is, after one of the scales 1 is installed, the second scale 1 can be positioned, and there is no need to adjust the installation position and height of the two ends of the second scale 1. It is more convenient to use, and it is also convenient to remove the scale 1 after the steel cage is positioned and installed.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
