Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hole pre-reservation devices, specifically a hole pre-reservation device for building engineering. Background Technology
[0002] In modern construction, precast concrete formwork has become a common building material. Many concrete formworks are equipped with embedded parts, reserved holes, and pre-drilled openings. These pre-drilled holes and openings on the formwork must be securely installed during formwork erection, and their positional deviations must comply with relevant regulations. In current concrete formwork production processes, when pre-drilled holes are required, the hole supports are typically placed directly into the uncured concrete. However, this method lacks an effective support structure, making the supports prone to tipping over during concrete curing, leading to production failure and affecting the quality and efficiency of the formwork. Utility Model Content
[0003] The present invention provides a hole pre-reservation device for building engineering, which solves the problem that existing hole support components are prone to tipping over during the concrete solidification process, leading to production failure.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A pre-drilled hole device for building construction includes a fixed frame with multiple telescopic frames arranged around its outer perimeter. Each telescopic frame has a mold frame abutment mechanism at its end. A mounting frame is rotatably connected to the lower side of the fixed frame. A power mechanism for rotating the mounting frame is mounted on the fixed frame. A position adjustment mechanism and a lifting mechanism are mounted on the position adjustment mechanism. The lifting mechanism is linearly displaced along the mounting frame by the position adjustment mechanism. A connecting platform is located at the lower end of the lifting mechanism, and a hole support component is detachably connected to the connecting platform. "Multiple" refers to at least three telescopic frames, equidistantly distributed circumferentially around the fixed frame (e.g., three frames spaced 120° apart, four frames spaced 90° apart). The hole support component utilizes existing technology; any support capable of pre-drilling holes during concrete formwork pouring is acceptable, such as a rod or pipe. In use, multiple telescopic frames can adjust their length according to the mold size. The mold frame abutment mechanism at the end can lock the mold frame, firmly installing the fixing frame on the mold. The power mechanism drives the mounting frame to rotate, adjusting its angle. The position adjustment mechanism drives the lifting mechanism to move linearly along the mounting frame, while the lifting mechanism raises and lowers the hole support component, ultimately adjusting it to the appropriate position and height, completing the hole pre-reservation preparation. This structure ensures the pre-reservation device is firmly installed on the mold, preventing displacement during operation, ensuring the stability of the hole support component, and preventing it from tipping over during concrete solidification. Simultaneously, the multi-mechanism coordination allows for adjustment of the hole support component in different dimensions, meeting various complex hole pre-reservation needs, greatly improving production success rate and construction efficiency.
[0006] Furthermore, the telescopic frame includes an outer frame and an inner frame mounted on the fixed frame. Two first guide rods are parallel to each other at the inner end of the outer frame. A first screw is rotatably connected to the outer frame, with the first guide rods and the first screw axis parallel to each other. The inner frame has a first rod hole slidably connected to the first guide rod and a first screw hole threadedly connected to the first screw. A first motor for driving the first screw to rotate is mounted on the outer frame. In use, when the first motor is started, it drives the first screw to rotate. Because the first screw hole on the inner frame is threadedly connected to the first screw, and the first rod hole is slidably connected to the first guide rod, under the guidance of the first guide rod, and because the inner frame is fixed to the fixed frame, the outer frame moves telescopically along the axis of the first screw, thereby adjusting the length of the telescopic frame. Using this structure, the telescopic frame can flexibly adjust its length according to different sizes of mold frames, ensuring that the mold frame abutment mechanism can accurately cooperate with the mold frame, making the pre-reservation device adaptable to various mold specifications and improving its versatility.
[0007] Furthermore, the mold frame abutment mechanism includes a lifting screw threadedly connected to the outer frame and a lifting guide rod slidably connected to the outer frame. A connecting block is rotatably connected to the lower end of the lifting screw, and the connecting block is fixedly connected to the lower end of the lifting guide rod. An L-shaped clamping plate is detachably connected to the lower side of the connecting block. A second motor is installed on the outer frame to drive the lifting screw to rotate. In use, after the second motor starts, it drives the lifting screw to rotate. Since the connecting block is rotatably connected to the lifting screw and fixedly connected to the lifting guide rod, under the guidance of the lifting guide rod, the connecting block will move up and down with the rotation of the lifting screw, thereby driving the L-shaped clamping plate to rise and fall. When the L-shaped clamping plate descends to the appropriate position, it can clamp the mold frame, firmly fixing the fixing frame to the mold. This structure, together with the telescopic frame, can firmly fix the fixing frame to the mold, effectively preventing the pre-reservation device from shifting due to external forces during concrete pouring, ensuring the accuracy of the hole support position, and thus improving the accuracy and quality of the hole pre-reservation.
[0008] Furthermore, the power mechanism includes a gear ring mounted on the fixed frame and a third motor mounted on the mounting frame. The output end of the third motor is provided with a drive tooth, which meshes with the gear ring. Specifically, the gear ring is fixedly connected to the fixed frame and can be either an internal or external gear ring. In use, when the third motor starts, the drive tooth at its output end begins to rotate. Because the drive tooth meshes with the gear ring on the fixed frame, the mounting frame rotates relative to the fixed frame under the action of gear transmission, thereby adjusting the angle of the hole support component. Using this structure, the angle of the hole support component can be easily and quickly adjusted through the power mechanism to meet the needs of various angle hole reservations in different construction projects, enhancing the applicability of the reservation device in complex construction scenarios.
[0009] Furthermore, the position adjustment mechanism includes fixed plates symmetrically arranged on the lower side of the mounting frame, a second guide rod between the two fixed plates, and a second screw rotatably connected to the two fixed plates. A fourth motor for driving the second screw to rotate is mounted on any one of the fixed plates. A displacement block is threadedly connected to the second screw, and the displacement block is slidably connected to the second guide rod. Specifically, a rotating shaft is provided between the upper side of the mounting frame and the fixed frame, and the two are rotatably connected via the rotating shaft. In use, the fourth motor is started, driving the second screw to rotate. Since the displacement block is threadedly connected to the second screw and slidably connected to the second guide rod, under the guidance of the second guide rod, the displacement block will achieve linear displacement along the second screw, thereby driving the lifting mechanism and the hole support connected to the displacement block to move to the desired position on the mounting frame. Using this structure, the position adjustment mechanism can achieve precise position adjustment of the hole support on the mounting frame, meeting the high-precision requirements for hole position in construction engineering, and improving the positioning accuracy and construction quality of the pre-reserved device.
[0010] Furthermore, the lifting mechanism includes a lifting cylinder mounted on the displacement block. A long rod is mounted at the output end of the lifting cylinder, and an outer sleeve is fitted onto the long rod. A spring is positioned between the end of the outer sleeve and the end of the long rod. The connecting platform is located at the lower end of the outer sleeve. Specifically, the lifting cylinder is positioned at the center of the displacement block, also on the line of symmetry between the second guide rod and the second screw, and the rotation point of the mounting bracket is also located on the line of symmetry between the second guide rod and the second screw. In use, after the lifting cylinder is activated, it drives the long rod to move up and down. As the long rod moves, the outer sleeve moves accordingly. With the buffering effect of the spring between the end of the long rod and the outer sleeve, the outer sleeve and the connecting platform can rise and fall smoothly, thereby raising and lowering the hole support on the connecting platform to a suitable height. With this structure, the spring makes the hole support more stable during lifting and lowering. The structure, which is combined with the outer sleeve that slides outside the long rod, avoids positional displacement caused by vibration or impact during lifting and lowering, ensuring the stability and accuracy of the hole reservation. Furthermore, after the hole support abuts against the lower end face of the mold, the spring provides a buffer space, thereby preventing long-term impact damage to the lifting cylinder and extending the service life of the reservation device.
[0011] Beneficial effects: 1. The telescopic frame and mold frame abutment mechanism can firmly fix the pre-drilled part onto the mold, effectively preventing displacement during operation, thus ensuring the stability of the hole support and preventing it from tipping over during concrete solidification, improving production success rate and the quality of building formwork. 2. The setting of the power mechanism, position adjustment mechanism, and lifting mechanism allows the hole support to be precisely adjusted in multiple dimensions, meeting the needs of hole pre-drilling of different sizes, positions, and angles, and cooperating with different molds, greatly improving the versatility and applicability of the pre-drilled part, and increasing the efficiency and flexibility of construction. 3. The detachable connection between the hole support and the connecting platform allows for the replacement of the hole support, enabling the pre-drilling of holes of different sizes, and allowing it to be disassembled from the connecting platform when the concrete is semi-solidified, thus moving other components for separate production, improving the utilization efficiency of other components.

A first screw 204 is rotatably connected to the outer frame 201, and the first guide rods 203 and the first screw 204 are axially parallel. The inner frame 202 has a first rod hole that is slidably connected to the first guide rods 203 and a first screw hole that is threadedly connected to the first screw 204.

The mold frame abutment mechanism 3 includes a lifting screw 301 threadedly connected to the outer frame 201 and a lifting guide rod 302 slidably connected to the outer frame 201. A connecting block 303 is rotatably connected to the lower end of the lifting screw 301, and the connecting block 303 is fixedly connected to the lower end of the lifting guide rod 302. An L-shaped clamping plate 304 is detachably connected to the lower side of the connecting block 303. A second motor 305 for driving the lifting screw 301 to rotate is provided on the outer frame 201. The power mechanism 5 includes a gear ring 501 disposed on the fixed frame 1 and a third motor 502 disposed on the mounting frame 4. The output end of the third motor 502 is provided with an active gear 503, which meshes with the gear ring 501. Specifically, the gear ring 501 is fixedly connected to the fixed frame 1 and can be either an internal gear ring or an external gear ring.The position adjustment mechanism 6 includes fixed plates 601 symmetrically arranged on the lower side of the mounting frame 4. A second guide rod 602 is arranged between the two fixed plates 601. A second screw 603 is rotatably connected to the two fixed plates 601. A fourth motor 604 for driving the second screw 603 to rotate is arranged on any of the fixed plates 601. A displacement block 605 is threadedly connected to the second screw 603.

Working Principle: When using this hole pre-drilling device for building construction, firstly, according to the dimensions of the mold frame, start the first motor 205. The rotation of the first screw 204 drives the inner frame 202 to extend and retract on the first guide rod 203, adjusting the length of the telescopic frame 2 so that the mold frame abutting mechanism 3 can be aligned with the mold frame. Then, start the second motor 305, driving the lifting screw 301 to rotate, causing the L-shaped clamping plate 304 to descend and clamp the mold frame, and together with the first motor 205 and other components, firmly fix the fixing frame 1 on the mold. When it is necessary to adjust the angle of the hole support 9, start the third motor 502. The third motor 502 drives the active gear 503 to rotate. The active gear 503 meshes with the toothed ring 501 on the fixing frame 1, realizing the rotation of the mounting frame 4 relative to the fixing frame 1, thereby adjusting the angle of the hole support 9. To precisely adjust the position of the hole support 9 on the mounting frame 4, start the fourth motor 604. The second screw 603 is rotated, and the displacement block 605, guided by the second guide rod 602, moves linearly along the second screw 603, moving the lifting mechanism 7 and the hole support 9 to the required position. Finally, the lifting cylinder 701 moves the long rod 702 up and down, and with the buffering effect of the spring 704, the outer rod 703 and the connecting platform 8 rise and fall smoothly, adjusting the hole support 9 to a suitable height or pressing it against the bottom of the mold, thus performing the hole pre-reservation work for the concrete formwork; ensuring the fixed position of the hole support 9.
