Description

Technical Field

[0001] This invention relates to the field of building piling technology, specifically to a piling auxiliary device used in building construction. Background Technology

[0002] The foundation of any building must be reinforced to support the structure. Piling is a process of installing piles in the foundation. In bored pile construction, a casing is inserted into the drilled hole, and then the concrete structure and reinforcing cage are poured into the casing. Current bored pile casings need to be promptly removed after the concrete is poured into the hole to prevent them from becoming stuck. However, when the casing is inserted into the hole, the foundation soil is in direct contact with the casing, which can easily cause adhesion and make removal difficult. Furthermore, when the reinforcing cage is inserted into the casing, it requires various auxiliary welded structures for support to ensure it is centered; adjustments are difficult if there are errors in the support.

[0003] Chinese patent CN116240877B discloses an auxiliary device for pile driving of building foundations in building construction. The device involves inserting the docking column of the operating platform into the docking groove in the casing, and then using a lifting cylinder to push the operating platform to move vertically in a reciprocating linear motion. During this process, the casing shakes continuously to prevent it from sticking to the foundation. At the same time, the hook plate continuously adjusts its length to connect one end with the reinforcing rib of the cage. The other end of the hook plate is fixed in position by a prismatic groove and a prismatic rod, so that the reinforcing rib of the cage can be stably positioned at the center of the casing.

[0004] However, this solution requires the docking column to be inserted into the casing before the hook plate can be operated. During disassembly, the hook plate must be detached from the cage reinforcement before the docking column can be moved. The entire operation process is fixed and cannot be changed, making the use of the equipment inconvenient. The sequential operation of several hook plates during disassembly makes the entire disassembly process time-consuming. At the same time, when the entire operating platform moves back and forth in the vertical direction, it will also move the hook plates. Although the hook plates can change their length according to the height of the operating platform, if a hook plate malfunctions and cannot be adjusted, the cage reinforcement will shift, thus affecting the normal progress of subsequent construction. Summary of the Invention

[0005] To address the aforementioned issues, a piling auxiliary device for building construction is provided. Through a casing control component and a rebar cage control component, the order of connecting the casing and the rebar cage does not need to be fixed. A fixed sleeve ensures that the position of the hook plate remains unchanged when the casing vibrates up and down. The cooperation of the first and second movable rings allows the hook plate to quickly and easily establish or disengage from the rebar cage.

[0006] To address the problems of existing technologies, a piling auxiliary device for building construction is provided, comprising a fixed base, a lifting disc, a casing control assembly and a rebar cage control assembly disposed inside the lifting disc. The rebar cage control assembly includes a fixed sleeve, a first movable ring, an operating panel, a second movable ring, and a hook plate. The fixed sleeve is coaxially sleeved on the outside of the lifting disc, and a support rod fixedly connected to the fixed base is fixedly installed at the bottom of the fixed sleeve. The casing control assembly includes a prismatic column extending upward along the axis of the fixed sleeve to the outside of the lifting disc, the prismatic column rotating with the lifting disc, and the first movable ring being coaxial with the fixed sleeve. In a sliding fit, the first movable ring is located inside the fixed sleeve. A protruding plate extending along the diameter of the first movable ring is fixedly installed on the inner side wall of the first movable ring, pointing towards the axis of the first movable ring. A circular through hole for the prismatic prism to pass through is opened on the protruding plate. The operating disk is rotatably located above the protruding plate and is coaxial with the circular through hole. A prismatic hole that slides with the prismatic prism is opened on the operating disk. The second movable ring is rotatably located outside the operating disk and is coaxial with the operating disk. One end of the hook plate is hinged to the outer side wall of the second movable ring, and the other end of the hook plate has a snap-fit ​​interface that contacts the reinforcing cage.

[0007] Preferably, an annular groove coaxial with the fixed sleeve is formed on the inner wall of the fixed sleeve, and a first guide shaft is fixedly arranged in the annular groove. The axis of the first guide shaft is parallel to the axis of the fixed sleeve, and a guide hole is formed on the first movable ring to slide with the first guide shaft.

[0008] Preferably, the fixed sleeve further includes a first spring, which is sleeved on the first guide shaft. One end of the first spring is fixedly connected to the bottom of the annular groove, and the other end of the first spring is fixedly connected to the bottom of the first movable ring.

[0009] Preferably, the first movable ring further includes a knob, a movable block, and an abutment plate. The knob is rotatably mounted on the protrusion plate, with its axis horizontal and perpendicular to the extension direction of the protrusion plate. The knob has an internal threaded hole coaxial with the knob. The movable block has a threaded shaft that is threadedly engaged with the internal threaded hole. The movable block is slidably mounted inside the protrusion plate along the axis of the knob and has a guide groove. The abutment plate is slidably mounted in the first movable ring along the diameter direction of the first movable ring and can protrude to the outside of the first movable ring. A second guide shaft that is slidably engaged with the guide groove is fixedly mounted on the abutment plate.

[0010] Preferably, a movable block is provided at both ends of the knob, and the movable blocks at both ends of the same knob move in opposite directions.

[0011] Preferably, a sponge sheet is attached to the end of the abutment plate facing the outside of the first movable ring.

[0012] Preferably, the control panel further includes a third movable ring, and there are two third movable rings. The two third movable rings are coaxially and fixedly connected by a third guide shaft. The third movable rings are coaxially rotatably sleeved on the outside of the control panel. The second movable ring is slidably engaged with the third guide shaft, and the second movable ring is coaxial with the third movable ring.

[0013] Preferably, the control panel also includes a second spring, with one end of the second spring fixedly disposed on each of the two third movable rings that are close to each other, and the other end of the second spring pointing to the second movable ring and fixedly connected to the second movable ring.

[0016] The advantages of this invention compared to the prior art are:

[0017] This invention enables the connection sequence of the casing and the rebar cage to be flexible by using a casing control component and a rebar cage control component. A fixed sleeve ensures the hook plate remains in the same position when the casing vibrates. First and second movable rings allow for quick and easy connection and disconnection of the hook plate from the rebar cage, reducing installation time and eliminating the need for a fixed sequence. This simplifies the use of the equipment and ensures the stability of the rebar cage during casing vibration, preventing disruption to subsequent operations. Attached Figure Description

Detailed Implementation

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figures 1-5As shown, a piling auxiliary device for building construction includes a fixed base 1, a lifting disc 2, a casing control assembly 3 and a rebar cage control assembly 4 disposed inside the lifting disc 2. The rebar cage control assembly 4 includes a fixed sleeve 41, a first movable ring 42, a control panel 43, a second movable ring 44, and a hook plate 45. The fixed sleeve 41 is coaxially sleeved on the outside of the lifting disc 2. A support rod 411 fixedly connected to the fixed base 1 is fixedly disposed at the bottom of the fixed sleeve 41. The casing control assembly 3 includes a prismatic column 31 extending upward along the axis of the fixed sleeve 41 to the outside of the lifting disc 2. The prismatic column 31 is rotatably engaged with the lifting disc 2. The first movable ring 42 is coaxially slidably engaged with the fixed sleeve 41. Inside the fixed sleeve 41, a protruding plate 421 extending along the diameter of the first movable ring 42 is fixedly installed on the inner side wall of the first movable ring 42. The protruding plate 421 points to the axis of the first movable ring 42. A circular through hole 422 for the prismatic column 31 to pass through is opened on the protruding plate 421. The operating disk 43 is rotatably installed above the protruding plate 421. The operating disk 43 is coaxial with the circular through hole 422. A prismatic hole 431 that slides with the prismatic column 31 is opened on the operating disk 43. The second movable ring 44 is rotatably installed outside the operating disk 43. The second movable ring 44 is coaxial with the operating disk 43. One end of the hook plate 45 is hinged to the outer side wall of the second movable ring 44. The other end of the hook plate 45 is provided with a snap-fit ​​interface 435 that contacts the reinforcing cage.

[0032] Place the fixed base 1 at the foundation where piling is to be carried out. Insert the casing and rebar cage into the foundation in sequence. Then, fix the casing using the casing control component 3. Next, move the first movable ring 42 and rotate the second movable ring 44 to engage any one of the hook plates 45 with the rebar cage. Then, fix the position of the first movable ring 42. Then, rotate the remaining second movable rings 44 in sequence to engage the remaining hook plates 45 with the rebar cage. At this time, start the lifting disc 2. As the casing moves with the lifting disc 2, the fixed sleeve 41 works with the first movable ring 42 to keep the position of the rebar cage fixed. After the piling work is completed, release the fixation of the first movable ring 42 and control the entire first movable ring 42 to move. All hook plates 45 are disconnected from the rebar cage at the same time. Compared with the prior art, the casing control assembly 3 and rebar cage control assembly 4 of the present invention eliminate the need for a fixed sequence of connecting the casing and the rebar cage. The fixed sleeve 41 ensures that the position of the hook plates 45 remains unchanged when the casing shakes up and down. The cooperation of the first movable ring 42 and the second movable ring 44 allows the hook plates 45 to quickly and easily connect or disconnect from the rebar cage, thereby reducing the time required for installation. At the same time, the entire usage process does not need to follow a fixed sequence, which facilitates the use of the entire equipment and ensures that the rebar cage can maintain its stability when the casing shakes, ensuring that subsequent work will not be affected.

[0033] See Figure 2 , Figure 3 and Figure 5 As shown: The inner wall of the fixed sleeve 41 is provided with an annular groove 412 coaxial with the fixed sleeve 41. A first guide shaft 413 is fixedly installed in the annular groove 412. The axis of the first guide shaft 413 is parallel to the axis of the fixed sleeve 41. A guide hole 423 is provided on the first movable ring 42 to slide with the first guide shaft 413.

[0034] Compared with the prior art, the annular groove 412 and the first guide shaft 413 of the present invention limit the movement path of the first movable ring 42, thereby ensuring that the control disk 43 will not disconnect from the prism 31 when the first movable ring 42 is in use.

[0035] See Figure 2 , Figure 3 and Figure 5 As shown: The fixed sleeve 41 also includes a first spring 414, which is sleeved on the first guide shaft 413. One end of the first spring 414 is fixedly connected to the bottom of the annular groove 412, and the other end of the first spring 414 is fixedly connected to the bottom of the first movable ring 42.

[0036] The first spring 414 always provides an upward force to the first movable ring 42. Compared with the prior art, the first spring 414 of the present invention limits the default position of the first movable ring 42, thereby enabling the first movable ring 42 to be reset while also facilitating the connection of the first hook plate 45.

[0037] See Figures 3-8 As shown: The first movable ring 42 also includes a knob 424, a movable block 425, and an abutment plate 426. The knob 424 is rotatably mounted on the protruding plate 421. The axis of the knob 424 is horizontal and perpendicular to the extension direction of the protruding plate 421. The knob 424 has an internal threaded hole 4241 coaxial with the knob 424. The movable block 425 is fixedly mounted with a threaded shaft 4251 that is threadedly engaged with the internal threaded hole 4241. The movable block 425 is slidably mounted inside the protruding plate 421 along the axial direction of the knob 424. The movable block 425 has a guide groove 4252. The abutment plate 426 is slidably mounted in the first movable ring 42 along the diameter direction of the first movable ring 42. The abutment plate 426 can protrude to the outside of the first movable ring 42. The abutment plate 426 is fixedly mounted with a second guide shaft 4261 that is slidably engaged with the guide groove.

[0038] The control knob 424 is rotated. When the knob 424 is rotated, it pushes the movable block 425 to move along the axis of the knob 424 through the threaded engagement. When the movable block 425 moves, the first guide shaft 413 inside the guide groove 4252 will move simultaneously. At this time, the abutment plate 426 will move simultaneously with the movement of the first guide shaft 413. Compared with the prior art, the knob 424 of the present invention controls the movement of the abutment plate 426 through the engagement of the guide groove and the second guide shaft 4261, thereby conveniently and quickly fixing the position of the first movable ring 42.

[0039] See Figures 6-8 As shown: A movable block 425 is provided at both ends of the knob 424, and the movable blocks 425 at both ends of the same knob 424 move in opposite directions.

[0040] Compared to the prior art, each knob 424 of the present invention is connected to a movable block 425 at both ends, so that all the abutment plates 426 can move synchronously when any knob 424 is rotated.

[0041] See Figures 6-7 As shown: A sponge sheet is attached to one end of the abutment plate 426 facing the outside of the first movable ring 42.

[0042] Compared with the prior art, the abutment plate 426 of the present invention contacts the fixed sleeve 41 through a sponge sheet with a high coefficient of friction, thereby increasing the squeezing friction between the abutment plate 426 and the fixed sleeve 41 and ensuring the fixed stability of the first movable ring 42.

[0043] See Figure 3 , Figure 4 , Figure 5 and Figure 10 As shown: The control panel 43 also includes a third movable ring 432. There are two third movable rings 432. The two third movable rings 432 are coaxially and fixedly connected by a third guide shaft 433. The third movable rings 432 are coaxially rotatably sleeved on the outside of the control panel 43. The second movable ring 44 is slidably engaged with the third guide shaft 433. The second movable ring 44 is coaxial with the third movable ring 432.

[0044] Once the first hook plate 45 is connected to the rebar cage and the position of the first movable ring 42 is fixed, the other hook plates 45 can be connected. If the connection between the hook plate 45 and the rebar cage cannot be completed, the second movable ring 44 can be moved slightly upwards to complete the connection between the hook plate 45 and the rebar cage. Compared with the prior art, the second movable ring 44 of the present invention can slide along the axis of the control disk, thereby facilitating the connection between the other hook plates 45 (excluding the first hook plate 45) and the rebar cage.

[0045] See Figure 3 , Figure 4 , Figure 5 and Figure 10 As shown: The control panel 43 also includes a second spring 434. One end of the second spring 434 is fixedly provided on the side of each of the two third movable rings 432 that are close to each other. The other end of the second spring 434 points to the second movable ring 44 and is fixedly connected to the second movable ring 44.

[0046] Compared to the prior art, the second spring 434 of the present invention provides elastic force to the second movable ring 44, thereby enabling all the hook plates 45 to maintain the same horizontal height.

[0047] See Figure 3 , Figure 4 , Figure 5 and Figure 10 As shown: The second movable ring 44 also includes a U-shaped component 441. The opening of the U-shaped component 441 points into the second movable ring 44 along the diameter direction of the second movable ring 44. The U-shaped component 441 is slidably arranged along the diameter direction of the second movable ring 44. The control panel 43 is provided with a card interface 435 for inserting the U-shaped component 441.

[0048] When the control U-shaped component 441 leaves the card interface 435, the second movable ring 44 can be controlled to rotate and move. Compared with the prior art, the U-shaped component 441 and the card interface 435 of the present invention limit the position of the second movable ring 44, thereby ensuring that the position of the second movable ring 44 connected to the hook plate 45 after connection will not change.

[0049] See Figure 3 , Figure 4 , Figure 5 and Figure 10 As shown: The second movable ring 44 also includes a tension spring 442. One end of the tension spring 442 is fixedly disposed on the outer side wall of the second movable ring 44. The tension spring 442 points to the outside of the second movable ring 44 along the diameter direction of the second movable ring 44. The U-shaped piece 441 is fixedly connected to the end of the tension spring 442 away from the second movable ring 44.

[0050] Compared to the prior art, the tension spring 442 of the present invention limits the default position of the U-shaped member 441, so that the position of the second movable ring 44 will not change when there is no external force.

[0051] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
