Description

Technical Field

[0001] The present invention relates to the technical field of bridge and culvert construction, and particularly to an anti-tilting structure for cast-in-place piles in bridge and culvert construction. Background Technique

[0002] Currently, in bored cast-in-place piles, steel casing is often buried to locate the pile position to be drilled. The casing is a steel casing with a wall thickness of 10 mm. When positioning the casing, first take the pile center as the center of the circle, and determine the position of the casing on the soil according to the radius of the casing. After the casing is in place, apply pressure to bury the casing about 50 cm. If it is difficult to press down, a part of the soil at the hole position can be dug out first, and then the casing is placed and buried underground. During the burying process, it should be checked whether the casing is vertical. If it is found to be skewed, it should be corrected in time.

[0003] When pouring concrete in bridge and culvert construction, first, the supporting casing supporting the steel bar cylinder needs to be inserted into the hole in the ground, and then the support frame is sleeved outside the casing, and the inclination angle of the casing is pushed by cylinders in four directions to ensure the verticality of the casing. However, when pouring concrete into the casing, as the concrete increases, the casing and the steel bar cylinder are prone to tilt during vibration. Thus, when the casing tilts, it may push the position of the support frame to move, making it inconvenient for the cylinders on the support frame to correct the position of the casing, and thus the phenomenon of displacement of the support frame may occur. For this reason, we propose an anti-tilting structure for cast-in-place piles in bridge and culvert construction. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-tilting structure for cast-in-place piles in bridge and culvert construction to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An anti-tilting structure for cast-in-place piles in bridge and culvert construction, comprising: a main support frame body;

There are four pressure-bearing inclined plates, and fixed feet are fixedly arranged below the four corners of the main support frame body. The main support frame body, the fixed feet, and the pressure-bearing inclined plates are integrally fixed.

[0009] Preferably, the limiting component includes a connecting foot plate. Both ends of the connecting foot plate are rotatably connected with a stepping force-bearing plate. The rotation angle range of the stepping force-bearing plate relative to the connecting foot plate through a rotating column is 0-90°, and the structure of the connecting foot plate is a right-angle structure.

[0010] Preferably, a ground drilling cone is fixedly arranged below the connecting foot plate. A pushing spring is sleeved outside the ground drilling cone, and a clamping hole is formed in the inner wall of the ground drilling cone.

[0011] Preferably, a guiding column penetrates through the inside of the ground drilling cone. One side of the guiding column penetrates through a limiting buckle corresponding to the clamping hole one by one. The other end of the limiting buckle is fixedly connected with an auxiliary column through a connecting rib, and the top end of the guiding column is fixedly connected with the support frame main body.

[0012] Preferably, the correction mechanism includes an installation clamping plate fixedly connected with the support frame main body. One side of the installation clamping plate is fixedly provided with a cylinder main body, and the output end of the cylinder main body is provided with a cylinder arm penetrating through the inside of the installation clamping plate and the support frame main body.

[0016] Preferably, a tape measure box is fixedly arranged above the installation clamping plate. A tape measure part is fixedly arranged inside the tape measure box, and the tape measure head of the tape measure part penetrates through one side of the tape measure box.

[0017] The present invention at least has the following beneficial effects:

[0018] When pouring concrete into the casing in the present invention, as the concrete increases, the casing and the steel bar casing are prone to tilt during vibration. Therefore, when the casing tilts, it may push the position of the support frame to move, making it inconvenient for the cylinder on the support frame to correct the position of the casing, and thus a phenomenon of support frame displacement may occur. Therefore, after the construction worker sleeves the support frame main body outside the casing, first make the four limiting components drill into the ground in sequence, and then correct the angle of the casing through the four cylinders. When the four limiting components are inserted into the ground, even when the tilted casing squeezes the support frame main body, the position of the support frame main body can be ensured to be stable.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-7 , the present invention provides a technical solution: Embodiment 1, an anti-tilting structure for bored piles in bridge and culvert construction, including: a main body 1 of the support frame;

[0029] a limiting component 3, the limiting component 3 is arranged inside the main body 1 of the support frame, there are four limiting components 3, and the limiting component 3 is used to fix the main body 1 of the support frame;

[0030] The correction mechanism 2 is fixedly arranged on the support frame main body 1. There are four correction mechanisms 2 installed, and the correction mechanism 2 is used to correct the steel cylinder or casing. When pouring concrete in bridge and culvert construction, first, the supporting casing needs to be inserted into the ground hole to fix and assist the steel cylinder. Then, the support frame is sleeved outside the casing, and the inclination angle of the casing is pushed by cylinders in four directions to ensure the verticality of the casing. However, when pouring concrete into the casing, as the concrete increases, the casing and the steel cylinder are prone to tilt during vibration. As a result, when the casing tilts, it may push the position of the support frame to move, making it inconvenient for the cylinders on the support frame to correct the position of the casing, and thus there may be a phenomenon of displacement of the support frame. Therefore, after the construction workers sleeve the support frame main body 1 outside the casing, first, the four limiting components 3 are successively drilled into the ground, and then the angles of the casing are corrected by the four cylinders. When the four limiting components 3 are inserted into the ground, even if the casing tilts and squeezes the support frame main body 1, the position of the support frame main body 1 can be ensured to be stable.

[0031] The support frame main body 1 includes a pressure-bearing inclined plate 12 fixedly connected to the support frame main body 1. There are four pressure-bearing inclined plates 12. Fixed feet 11 are fixedly arranged below the four corners of the support frame main body 1. The support frame main body 1, the fixed feet 11, and the pressure-bearing inclined plate 12 are integrally fixed. First, the support frame main body 1 is sleeved outside the casing, and the four fixed feet 11 are all in contact with the ground, so as to ensure the stability of the support frame main body 1 on the ground.

[0032] The limiting component 3 includes a connecting foot plate 32. Rotating force-bearing plates 31 are rotatably connected to both ends of the connecting foot plate 32. The rotation angle range of the rotating force-bearing plate 31 relative to the connecting foot plate 32 through the rotating column is 0 - 90°, and the structure of the connecting foot plate 32 is a right-angle structure.

[0033] A drilling cone 34 is fixedly arranged below the connecting foot plate 32. A pushing spring 35 is sleeved outside the drilling cone 34. A clamping hole 38 is opened on the inner wall of the drilling cone 34. After placing the support frame main body 1 in the designated position, the construction workers can successively rotate the rotating force-bearing plates 31 out of the contraction grooves 13 on the side walls of the fixed feet 11 to make the rotating force-bearing plates 31 horizontal with the connecting foot plate 32. Then, the staff can step on two rotating force-bearing plates 31 with both feet at the same time, so that the connecting foot plate 32 slides downward along the limiting sliding grooves 14 on the contraction grooves 13, and thus the drilling cone 34 can be inserted into the ground. In this way, the staff steps all the drilling cones 34 of the four limiting components 3 into the ground to ensure the stability of the entire support frame main body 1.

[0034] A guide post 33 is inserted inside the earth-boring cone 34. A limit buckle 37 corresponding to the clamping holes 38 one by one is inserted on one side of the guide post 33. The other end of the limit buckle 37 is fixedly connected to the auxiliary post 36 through a connecting rib. The top end of the guide post 33 is fixedly connected to the support frame main body 1. When the staff steps on the force-bearing plate 31 to drive the earth-boring cone 34 to insert into the soil, the earth-boring cone 34 can extend downward along the guide post 33. And when the force-bearing plate 31 reaches the bottom, the limit buckle 37 can be buckled into the clamping hole 38, so as to ensure that the earth-boring cone 34 will not retract. After the device is used, the staff can press the auxiliary post 36. Through the auxiliary post 36, the connecting rib can be moved backward, so as to drive the retraction of the limit buckle 37. At the same time, through the elasticity of the pushing spring 35, the earth-boring cone 34 can be assisted to retract into the fixed foot 11.

[0035] According to the above embodiment, Embodiment 2, the correction mechanism 2 includes a mounting clamp plate 204 fixedly connected to the support frame main body 1. A cylinder main body 21 is fixedly arranged on one side of the mounting clamp plate 204. The output end of the cylinder main body 21 is provided with a cylinder arm 23 that penetrates through the inside of the mounting clamp plate 204 and the support frame main body 1.

[0036] An installation head 28 is arranged inside the top end of the cylinder arm 23. A clamping groove 29 is opened on the upper wall of the installation head 28. Above the clamping groove 29, a magnetic plate 201 movably connected to the inside of the cylinder arm 23 is arranged. The size of the magnetic plate 201 matches the size of the clamping groove 29. The structure of the magnetic plate 201 is a semi-circular structure.

[0037] Limit posts 202 are inserted through both sides of the magnetic plate 201. A return spring 203 located above the magnetic plate 201 is arranged outside the limit posts 202. The magnetic plate 201 is slidably connected to the limit posts 202.

[0038] At the other end of the mounting head 28, a push top plate 25 with an arc-shaped structure is fixedly arranged. On the other side of the push top plate 25, a protective rubber pad 27 with the same size as the push top plate 25 is fixedly glued. Above the mounting head 28, a magnet 26 that is adhesively connected to the push top plate 25 is arranged. After the main body 1 of the support frame is fixed by the four limiting components 3, the staff needs to connect the air pipes to the air pipe connectors 205 on the cylinder main bodies 21 respectively, so as to provide power for the four cylinder main bodies 21. When the casing and the steel bar cylinder are inclined, the cylinder main body 21 in the inclination direction of the casing works, so that the cylinder arm 23 extends to push the casing through the push top plate 25, thereby achieving the effect of correcting the inclination angle of the casing. When it is necessary to replace the push top plate 25 with different shapes, the staff only needs to move the magnet 26 from the push top plate 25 to the cylinder arm 23, and then the magnet 26 can suck the magnetic plate 201 upward by its adsorption property, so that the magnetic plate 201 withdraws from the clamping groove 29, and in this way, the mounting head 28 can be pulled out from the cylinder arm 23, and then it is convenient to replace the push top plate 25 with different shapes.

[0039] According to the above-mentioned embodiment, Embodiment 3, above the mounting clip 204, a tape measure box 22 is fixedly arranged. Inside the tape measure box 22, a tape measure member 24 is fixedly arranged. The tape head of the tape measure member 24 penetrates through one side of the tape measure box 22. While the push top plate 25 moves along with the cylinder arm 23, the tape measure member 24 can be adsorbed by the magnetism of the magnet 26, so that the tape measure member 24 is stretched, thereby facilitating the staff to accurately see the size of the pushing arc of the cylinder main body 21.
