Description
Technical Field
[0001] This application relates to the field of pile foundation construction, and more specifically, to a fixing device for embedded parts in pile foundations. Background Technology
[0002] Pile foundations are a common type of foundation used in building construction. They involve driving or pressing piles into the soil, using the friction or end bearing force between the piles and the surrounding soil to bear the load of the superstructure. During the construction of pile foundations, embedded parts are important components that connect the superstructure and the pile foundation, and their fixing effect directly affects the stability and safety of the entire structure.
[0003] However, in the existing pile foundation construction process, due to the huge pressure and flow generated during concrete pouring, the embedded parts are prone to displacement, which affects their connection with the superstructure. Therefore, it is necessary to fix the embedded parts. The traditional method of fixing embedded parts is to use bolts for connection and fixation. However, the traditional embedded part fixing device is fixed with fixing holes. Different embedded parts have different structural dimensions, which means that each embedded part of a certain size needs to be equipped with an independent fixing device, which increases the construction cost. To this end, this application proposes a pile foundation embedded part fixing device to solve the above problems. Utility Model Content
[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a fixing device for embedded parts in pile foundations, including a base plate. The base plate is configured as a frame structure, and side plates are provided on both sides of the upper surface of the base plate. Sleeve blocks are mounted on the side plates, and the sleeve blocks can slide along the length direction of the side plates. Positioning members for positioning the sleeve blocks on the side plates are mounted on the sleeve blocks, and support members are horizontally mounted on the sleeve blocks. The support members are distributed along the width direction of the base plate, and a sleeve is mounted on one end of the support members facing inwards from the base plate. The support members can move progressively along the width direction of the base plate.
[0006] Preferably, the sleeve is configured as a "∩" shape, and the "∩" shaped sleeve is slidably fitted onto the side plate.
[0007] Preferably, a groove is provided on the side plate along the length direction, and a slider is provided inside the sleeve block and is slidably embedded in the groove.
[0008] Preferably, the support member is a screw with a horizontal thread passing through the sleeve block, the screw is rotatably connected to the sleeve, and a handle is fixed to the other end of the screw.
[0009] Preferably, the screw passes through the slide groove, and the slider is movably sleeved with the screw.
[0010] Preferably, the positioning element is a first bolt threaded through the top of the sleeve block, and tightening the first bolt can abut against the upper surface of the side plate.
[0011] Preferably, auxiliary fixing members are provided at both ends of the substrate. The auxiliary fixing members include pressure plates provided at the top of both ends of the substrate. Multiple drill rods are vertically fixed on the lower surface of the pressure plates. The drill rods vertically penetrate the substrate, and the bottom end of the drill rods is provided with a conical spike.
[0012] Preferably, a second bolt is threaded vertically through the pressure plate, and the bottom end of the second bolt is rotatably connected to the substrate.
[0013] The beneficial effect of this application is that it provides an adjustable fixing device for embedded parts in pile foundations.
[0014] With the aid of fixing components, after the pile foundation embedded part is placed in the embedded pit, the base plate is placed horizontally on the ground at the top of the embedded pit. Tightening the second bolt rotates the plate and pushes it down, allowing the drill rod to be inserted into the ground at the top of the embedded pit to reinforce the base plate. The sleeve is connected to the vertical rod of the pile foundation embedded part. Tightening the first bolt abuts against the upper surface of the side plate, positioning the sleeve block on the side plate. Utilizing the cooperation and support of the side plate, sleeve block, screw, and sleeve, the base plate and the pile foundation embedded part can be positioned relative to each other, thus fixing the embedded part and preventing the embedded part from shifting due to the huge pressure and flow during concrete pouring, which would affect the connection between the embedded part and the superstructure.
[0015] By setting up the support components and the sliding fit between the sleeve block and the side plate, the lateral position of the sleeve can be adjusted by turning the screw and moving it forward. The sleeve block slides on the side plate and is tightened and positioned with the first bolt, which can adjust the longitudinal position of the sleeve. The longitudinal and lateral adjustment of the sleeve can fix the embedded parts of pile foundations of different sizes and structures, and has high adaptability. Attached Figure Description

[0031] Reference Figures 1-5 As shown, this application provides a fixing device for embedded parts in pile foundations, including a base plate 1. The base plate 1 is configured as a frame structure. Side plates 2 are provided on both sides of the upper surface of the base plate 1. Sleeve blocks 3 are mounted on the side plates 2. The sleeve blocks 3 can slide along the length direction of the side plates 2. Positioning members for positioning the sleeve blocks 3 on the side plates 2 are mounted on the sleeve blocks 3. Support members 4 are horizontally mounted on the sleeve blocks 3. The support members 4 are distributed along the width direction of the base plate 1. A sleeve 5 is mounted on one end of the support member 4 facing inwards from the base plate 1. The support member 4 can move progressively along the width direction of the base plate 1. With this structure, after the embedded part of the pile foundation is placed in the pre-embedded pit, the base plate 1 is placed horizontally on the ground at the top of the pre-embedded pit. The sleeve blocks 3 are moved so that the sleeve 5 is aligned with the vertical rod of the embedded part of the pile foundation and sleeved on the vertical rod. The sleeve 3 is positioned on the side plate 2 using the positioning component. Thus, the side plate 2, sleeve 3, support component 4, and sleeve 5 work together to position the base plate 1 relative to the pile foundation embedded part, thereby fixing the pile foundation embedded part and avoiding the problem of the embedded part shifting due to huge pressure and flow during the concrete pouring process, which affects the connection between the embedded part and the superstructure. The sleeve 3 can slide along the length of the side plate 2 and the positioning component can be used to adjust the longitudinal position of the sleeve 5. The support component 4 can move progressively along the width of the base plate 1 to adjust the lateral position of the sleeve 5. The longitudinal and lateral adjustment of the sleeve 5 can fix the pile foundation embedded parts of different sizes.
[0032] In a further embodiment, the sleeve 3 is configured as a "∩" shape. The "∩" shaped sleeve 3 is slidably fitted onto the side plate 2. A groove 6 is provided on the side plate 2 along the length direction. A slider 9 is provided inside the sleeve 3 and is slidably embedded in the groove 6 to realize the sliding of the sleeve 3 on the side plate 2.
[0033] In this embodiment, the support member 4 is a screw 8 with a horizontal thread passing through the sleeve 3. The screw 8 is rotatably connected to the sleeve 5. The other end of the screw 8 is fixed with a handle 11. By turning the screw 8, the sleeve 5 can be pushed to move horizontally and the lateral position of the sleeve 5 can be adjusted. The screw 8 passes through the slide groove 6. The slider 9 is movably sleeved with the screw 8, which plays the role of preventing the sleeve 3 from falling off the side plate 2.
[0034] In this embodiment, the positioning element is a first bolt 10 threaded through the top of the sleeve block 3. Tightening the first bolt 10 can abut against the upper surface of the side plate 2. By tightening the first bolt 10 to abut against the upper surface of the side plate 2, the sleeve block 3 can be positioned on the side plate 2.
[0035] In a further embodiment, auxiliary fixing members 7 are provided at both ends of the substrate 1. The auxiliary fixing members 7 include pressure plates 12 provided at the top of both ends of the substrate 1. Multiple drill rods 14 are vertically fixed on the lower surface of the pressure plate 12. The drill rods 14 vertically penetrate the substrate 1. The bottom end of the drill rods 14 is provided with a conical spike. A second bolt 13 is vertically threaded through the pressure plate 12. The bottom end of the second bolt 13 is rotatably connected to the substrate 1. By using a wrench to turn the second bolt 13, the pressure plate 12 is pushed down, so that the drill rods 14 are inserted into the ground at the top of the pre-embedded pit, thereby reinforcing the substrate 1, preventing the substrate 1 from shifting on the ground, and improving the fixing effect of the pre-embedded parts of the pile foundation.
[0036] In use, after the pile foundation embedded part is placed in the embedded pit, the base plate 1 is placed horizontally on the ground at the top of the embedded pit. A wrench is used to turn the second bolt 13, pushing the pressure plate 12 down and causing the drill rod 14 to insert into the ground at the top of the embedded pit, reinforcing the base plate 1. Then, the sleeve block 3 is moved so that the sleeve 5 is aligned with the vertical rod of the pile foundation embedded part and fitted onto the vertical rod. Then, the first bolt 10 is tightened to abut against the upper surface of the side plate 2, positioning the sleeve block 3 on the side plate 2. Thus, using the cooperation and support of the side plate 2, sleeve block 3, screw rod 8, and sleeve 5, the base plate can be secured. 1. The sleeve 5 is positioned relative to the embedded parts of the pile foundation to fix them, thus avoiding the problem of the embedded parts shifting due to huge pressure and flow during the concrete pouring process, which would affect the connection between the embedded parts and the superstructure. Furthermore, by turning the screw 8 to move it forward, the lateral position of the sleeve 5 can be adjusted. The sleeve block 3 slides on the side plate 2 and is tightened and positioned in conjunction with the first bolt 10 to adjust the longitudinal position of the sleeve 5. The longitudinal and lateral adjustment of the sleeve 5 can fix the embedded parts of the pile foundation with different sizes and structures, and has high adaptability.
