Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a civil engineering pile foundation fixing structure. Background Art

[0002] A pile foundation is a deep foundation (see figure) consisting of a pile and a pile cap connected to the top of the pile (referred to as the cap) or a single pile foundation connected by a column and the pile foundation. It is referred to as a pile foundation. Pile foundation is an ancient technology in construction engineering. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations. Pile foundations are widely used in high-rise buildings. High pile cap foundations have been widely used due to their convenience in construction.

[0003] The existing application number is 202210100617.5, which is a civil engineering pile foundation fixing structure, comprising an arc-shaped fixing plate, the outer surface of which is fixedly connected to a support rod, the end of which is away from the arc-shaped fixing plate, is fixedly connected to an arc-shaped support seat, and the two arc-shaped fixing plates are threadedly connected by nuts. In the civil engineering pile foundation fixing structure, when the staff supports and fixes the pile foundation, the extrusion rod will be subjected to the extrusion force of the pile foundation, and when the pile foundation shakes after long-term use, the extrusion rod will move toward the inside of the arc-shaped fixing plate under the effect of the shaking, and the back-and-forth movement of the extrusion rod will cause the arc-shaped rotating rod to rotate under the action of the limit rod, thereby squeezing the extrusion deformation rod, which can cause the extrusion deformation rod to deform under the extrusion effect, thereby having a certain buffering effect on the shaking of the pile foundation, thereby enhancing the fixing effect of the device on the pile foundation.

When in use, turning the handle 4031 will drive the screw rod 403 to rotate. During the rotation of the screw rod 403, it will be limited by the limiting block 102, thereby pushing the limiting roller 4 through the mounting frame 402 to make it contact with the surface of the pile foundation. Similarly, the four limiting rollers 4 are squeezed and fixed to each other, thereby achieving the limitation of the pile foundation, which is beneficial to improving the stability of the device.

[0018] like Figure 5 As shown, the upper surface of the support plate 1 is provided with support plates 101 in a circular shape and at equal intervals, and the top of the support plate 101 is fixedly connected to a limiting block 102, and the inner wall of the limiting block 102 is threadedly connected to the side of the screw rod 403. When in use, the supporting plate 101 can provide auxiliary support to the limiting roller 4, and the limiting block 102 is threadedly connected to the side of the screw rod 403 to limit the screw rod 403, thereby limiting the limiting roller 4, which is beneficial to improving the flexibility of the device.

[0019] like Figure 3As shown, the side of the mounting tube 2 is annularly fixedly connected with a fixing frame 201, the interior of the fixing frame 201 is movably connected with a limiting rod 202, one end of the limiting rod 202 is fixedly connected with a fixing block 203, the fixing block 203 is fixedly connected to the clamping plate 5, and a spring 204 is sleeved on the outer side of the limiting rod 202, and the two ends of the spring 204 are respectively against the fixing frame 201 and the fixing block 203. When in use, the limiting rod 202 is provided, which is fixed through the fixing block 203 and the clamping plate 5 The connection is achieved by the mutual limitation of the limit rod 202 and the screw rod 2 502, so as to limit the clamping plate 5, and the spring 1 204 is provided, which will produce deformation during the movement of the clamping plate 5, so that the elastic force of the spring 1 204 is changed. At this time, the spring 1 204 will push the clamping plate 5 through its own elastic force, so that it will produce traction force on the screw rod 2 502, thereby preventing the screw rod 2 502 from loosening without the action of external force, thereby improving the stability of the device.

[0020] like Figure 4 As shown, the surface of the base 3 is arranged with fixing bolts 301 in an annular shape and at equal intervals, and the tops of the fixing bolts 301 are fixedly connected with baffles 302, and the sides of the fixing bolts 301 are arranged with grooves 3011 in an annular shape and at equal intervals, and the inner walls of the grooves 3011 are movably connected with support arms 303, and the sides of the support arms 303 are fixedly connected with springs 304, and the other ends of the springs 304 are fixedly connected to the inner walls of the grooves 3011. When in use, the fixing bolt 301 is inserted into the ground during installation through the support arms 303 and springs 304, so as to fix the device. At the same time, after the fixing bolt 301 is inserted into the ground, the springs 304 will push the support arms 303 to unfold from the inside of the grooves 3011 through their own elastic force, thereby increasing the grip of the fixing bolt 301, and preventing the device from shaking due to the loosening of the fixing bolt 301 during long-term use, thereby improving the stability of the device.

[0021] like Figure 3As shown, a non-slip pad 501 is fixedly connected to the side of the splint 5, and a screw rod 2 502 is fixedly connected to the other side of the splint 5 through a bearing. The other end of the screw rod 2 502 is fixedly connected to a handle 2 5021. The side of the screw rod 2 502 is threadedly connected to a limiting block 2 5022, and the limiting block 2 5022 is fixedly connected to the bottom end of the fixing frame 201. When in use, through the provided splint 5, when installing, rotating the handle 2 5021 can drive the screw rod 2 502 to rotate. When the screw rod 2 502 rotates, it will be pushed by the limiting block 2 5022 to limit the splint 5, so that the splint 5 drives the non-slip pad 501 to contact the surface of the pile foundation, and the pile foundation is fixed by the mutual extrusion and clamping of the three splints 5. In addition, the provided non-slip pad 501, which is made of rubber material, can increase the friction between the pile foundation and the splint 5, thereby improving the fixing effect of the device.

[0022] like Figure 6 As shown, the side surfaces of the sleeve rod 6 are linearly and equidistantly provided with locking grooves 601, the bottom ends of the inner walls of the sleeve rod 6 are movably connected with support rods 602, the bottom ends of the support rods 602 are fixedly connected to the upper surface of the base 3, and the top ends of the support rods 602 are provided with mounting grooves 6021. When in use, the locking grooves 601 are provided, which will engage with the locking blocks 7 to fix the positions of the sleeve rod 6 and the support rods 602, and the height of the device can be adjusted by adjusting different locking grooves 601 and locking blocks 7 to counteract each other, which is beneficial to improving the flexibility of the device.

[0023] like Figure 6 As shown, the locking blocks 7 are all located on the inner wall of the mounting groove 6021, one end of the locking blocks 7 extends to the outside of the mounting groove 6021 and is adapted to the inner wall of the locking groove 601, and the other end of the locking blocks 7 is fixedly connected to the spring three 701, and the other end of the spring three 701 is against the inner wall of the mounting groove 6021. When in use, the spring three 701 will push the spring three 701 through its own elastic force, so that it extends from the inside of the mounting groove 6021 and is stuck in the inside of the locking groove 601, thereby fixing the position of the sleeve rod 6 and the support rod 602, thereby improving the stability of the device.

[0024] The working principle of the present invention is as follows: first, the device is installed to a suitable position. During this process, the fixing bolt 301 is inserted into the ground to fix the device. At the same time, after the fixing bolt 301 is inserted into the ground, the spring 2 304 will push the support arm 303 to unfold from the inside of the groove 3011 through its own elastic force, thereby increasing the grip of the fixing bolt 301, which can prevent the device from shaking due to the loosening of the fixing bolt 301 during long-term use, thereby improving the stability of the device, and then adjust the height of the device according to the height of the pile foundation. During this process, first press the locking block 7 to move it out from the inside of the locking groove 601 and retract it into the inside of the installation groove 6021, so that the support rod 602 can move up and down inside the sleeve rod 6, thereby realizing the position of the fixing mechanism in the device. When the screw rod 403 is adjusted to a suitable position, the spring 3 701 will push the spring 3 701 through its own elastic force, so that it extends from the inside of the installation slot 6021 and is stuck in the inside of the locking slot 601, thereby fixing the position of the sleeve rod 6 and the support rod 602. By adjusting different locking slots 601 and locking blocks 7 to abut against each other, the height adjustment of the device is achieved, which is beneficial to improving the flexibility of the device. When the screw rod 403 is adjusted to a suitable position, the handle 1 4031 is first turned, which will drive the screw rod 1 403 to rotate. During the rotation of the screw rod 1 403, it will be limited by the limiting block 102, thereby pushing the limiting roller 4 through the mounting frame 402 to make it contact with the surface of the pile foundation. Similarly, the four limiting rollers 4 are squeezed and fixed to each other, thereby limiting the pile foundation, which is beneficial to improving the stability of the device. When installing, the second handle 5021 is turned to drive the second screw rod 502 to rotate. When the second screw rod 502 rotates, it will be pushed by the second limit block 5022 to limit the position of the splint 5, so that the splint 5 drives the anti-skid pad 501 to contact the surface of the pile foundation, and the three splints 5 are mutually squeezed and clamped to fix the pile foundation. The anti-skid pad 501 is cast from rubber material, which can increase the friction between the pile foundation and the splint 5, thereby improving the fixing effect of the device. The rod 202 is fixedly connected to the splint 5 by the fixing block 203, and the splint 5 is limited by the mutual limitation of the limiting rod 202 and the screw rod 2 502. In addition, the spring 1 204 is provided, which will be deformed during the movement of the splint 5, so that the elastic force of the spring 1 204 is changed. At this time, the spring 1 204 will push the splint 5 by its own elastic force, so that it will generate traction force on the screw rod 2 502, thereby preventing the screw rod 2 502 from loosening without the action of external force, thereby improving the stability of the device.
