Description

Technical Field

[0001] This utility model relates to the field of precast beam support technology, specifically to a precast beam support and positioning auxiliary device. Background Technology

[0002] In the field of building construction, the installation of precast beams is of paramount importance. Traditional methods of supporting and positioning precast beams have many drawbacks. On the one hand, in terms of support stability, the previous support structures are difficult to adapt to the weight and size of precast beams of different specifications, which can easily lead to situations such as tilting of the support beams and columns and displacement of the precast beams, which greatly affect the construction quality and safety. For example, in some large-scale construction projects, the instability of the support has led to the installation deviation of the precast beams, which has to be reworked and adjusted, consuming a lot of manpower, material resources and time costs.

[0003] On the other hand, in terms of positioning, traditional methods cannot meet the increasingly higher requirements for construction precision. Minor positioning errors during the installation of precast beams may have a cumulative effect when the overall building structure is subjected to stress, weakening the load-bearing capacity and stability of the building structure. At the same time, the lack of an effective buffer mechanism makes the precast beams susceptible to damage to the supporting structure and the beam itself due to impact forces during hoisting and placement. Utility Model Content

[0004] The purpose of this utility model is to provide a precast beam support and positioning auxiliary device, which solves the technical problems of traditional precast beam support structures being unable to adapt to the weight and size of precast beams of different specifications, and being prone to problems such as tilting of support beams and columns, displacement of precast beams, and inconvenience of installation and disassembly. It achieves the purpose of positioning precast beams, improving construction efficiency, simplifying the structure of support devices, and facilitating their installation and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precast beam support and positioning auxiliary device, comprising a support beam column, an adjustable positioning base, and a precast beam buffer support, wherein a precast beam is fixedly installed between the support beam columns; the adjustable positioning base is disposed between the support beam columns; and the precast beam buffer support is disposed between the support beam column and the adjustable positioning base.

[0006] Preferably, the adjusting positioning base specifically includes: a support base, disposed at the bottom of the precast beam; positioning slides, symmetrically disposed at the bottom of the precast beam; and threaded sleeves, symmetrically disposed on the top outer wall of the support base.

[0007] Positioning sliding columns are installed to provide precise guidance for the movement of the support base, ensuring that the support base can move smoothly in the predetermined direction during adjustment. This makes the position adjustment of the precast beam more accurate, improves positioning accuracy, ensures that the installation position of the precast beam meets design requirements, and enhances the overall stability and quality of the building structure. The symmetrically arranged positioning sliding columns, in conjunction with the installation sliding sleeves, effectively limit the horizontal displacement of the support base, enhancing the structural stability of the entire support system during operation. When bearing the weight of the precast beam and the vibrations and impacts that may occur during construction, it can prevent the support base from shaking or shifting, maintain the stability of the support system, and reduce safety risks.

[0008] Preferably, the threaded sleeve is fixedly installed on the top outer wall of the support base, and the top outer wall of the support base is symmetrically fixedly installed with mounting sliding sleeves, and the threaded sleeve is internally threaded with a horizontal adjusting threaded rod.

[0009] Preferably, one end of the horizontal adjusting threaded rod passes through the top outer wall of the support base via a threaded sleeve and extends to the bottom outer wall of the support base, and the other end of the horizontal adjusting threaded rod extends to the top of the threaded sleeve via a threaded sleeve, and a support pad is fixedly installed at one end of the horizontal adjusting threaded rod.

[0010] Preferably, the support pad is located at the bottom of the support base, and the other end of each horizontal adjusting threaded rod is fixedly connected to a rotating block. The rotating block is located at the top of the support base, and the support base is movably fitted onto the outer wall of the positioning slide column by means of a sliding sleeve.

[0011] Preferably, the precast beam buffer support specifically includes: a spring positioning sleeve, which is circumferentially and equidistantly fixed on the top outer wall of the support base; a damping telescopic rod, which is disposed on the top of the support base; and a buffer support platform, which is disposed on the top of the support base.

[0012] The system incorporates damping telescopic rods that work in conjunction with buffer springs and buffer pads to effectively enhance the stability of the entire support system. When the precast beam is subjected to external vibrations or its own weight, the damping telescopic rods provide stable resistance, preventing excessive rebound or vibration of the support structure caused by the elastic action of the buffer springs. This keeps the precast beam stable and ensures construction safety. When used in conjunction with electric telescopic rods, the damping telescopic rods optimize the precast beam height adjustment process. While the electric telescopic rods adjust the support height, the damping telescopic rods prevent sudden height changes caused by excessively rapid movement of the electric telescopic rods or uneven weight distribution of the precast beam, making the adjustment process smoother. This helps improve the positioning accuracy of the precast beam and ensures that the installation position meets design requirements.

[0013] Preferably, a buffer spring is provided inside the spring positioning sleeve, and buffer pads are fixedly installed circumferentially on the bottom outer wall of the buffer support platform. Spring mounting positioning blocks are fixedly installed on the bottom outer wall of each buffer pad. One end of the buffer spring is fixedly connected to the top outer wall of the support base, and the other end of the buffer spring is fixedly connected to the bottom outer wall of the buffer pad.

[0014] Preferably, the buffer spring is sleeved on the outer wall of the spring mounting positioning block, the damping telescopic rod is fixedly installed on the top outer wall of the support base, the telescopic end of the damping telescopic rod is fixedly connected to the bottom outer wall of the buffer support platform, an electric telescopic rod is fixedly installed on the top outer wall of the buffer support platform, a support pad is fixedly installed on the telescopic end of the electric telescopic rod, and the top outer wall of the support pad is in contact with the bottom outer wall of the precast beam.

[0015] This utility model provides a precast beam support and positioning auxiliary device. It has the following beneficial effects:

[0016] (1) This utility model uses the threaded connection between the horizontally sleeved threaded rod and the threaded sleeve. By rotating the rotating block, the horizontally sleeved threaded rod can be driven to move up and down inside the threaded sleeve, thereby driving the support pad to rise or fall and adjusting the horizontal height of the precast beam. The symmetrically arranged positioning slide and threaded sleeve, as well as the support pads at both ends of the horizontally sleeved threaded rod, can provide stable support for the precast beam, distribute the weight of the precast beam, reduce the risk of deformation or damage to the precast beam caused by single-point support or uneven support, and improve the stability and reliability of the entire support structure.

[0017] (2) This utility model can effectively buffer the impact force generated during the placement of precast beams and the influence of external vibrations through the combination of buffer springs and damping telescopic rods. When the precast beam falls or is vibrated, the buffer spring first absorbs part of the energy through its own elastic deformation, and the damping telescopic rod further suppresses the rebound of the spring, reduces the duration and amplitude of vibration, and protects the precast beam from damage. The electric telescopic rod can adjust the height of the support pad according to actual needs to adapt to the height requirements of different precast beams and adjustments during construction.

Example

[0025] The existing precast beam support structures are difficult to adapt to the weight and size of precast beams of different specifications, and are prone to problems such as beam tilting, precast beam displacement, and inconvenience in installation and disassembly. Therefore, this utility model provides a preferred embodiment of a precast beam support and positioning auxiliary device, for example... Figures 1-4 As shown: A precast beam support and positioning auxiliary device includes a support beam column 1, an adjusting and positioning base part 3, and a precast beam buffer support part 4. A precast beam 2 is fixedly installed between the support beam columns 1; the adjusting and positioning base part 3 is disposed between the support beam columns 1; and the precast beam buffer support part 4 is disposed between the support beam column 1 and the adjusting and positioning base part 3.

[0026] The adjusting positioning base 3 specifically includes: a support base 311, which is set at the bottom of the precast beam 2; positioning slides 313, which are symmetrically set at the bottom of the precast beam 2; and threaded sleeves 314, which are symmetrically set on the top outer wall of the support base 311.

[0027] The threaded sleeve 314 is fixedly installed on the top outer wall of the support base 311. The top outer wall of the support base 311 is symmetrically fixedly installed with mounting sleeves 312. The threaded sleeve 314 is internally threaded with a horizontal adjusting threaded rod 316.

[0029] The support pad 317 is set at the bottom of the support base 311, and the other end of the horizontal adjusting threaded rod 316 is fixedly connected to the rotating block 315. The rotating block 315 is set at the top of the support base 311, and the support base 311 is movably sleeved on the outer wall of the positioning slide column 313 by installing the sliding sleeve 312.

[0030] In this embodiment, if it is necessary to adjust the height of the precast beam 2, rotate the rotating block 315 to drive the horizontal threaded rod 316 to rotate within the threaded sleeve 314, causing the support pad 317 to rise or fall, thereby adjusting the height of the support base 311 and the precast beam 2. This can provide stable support for the precast beam, distribute the weight of the precast beam, reduce the risk of deformation or damage to the precast beam caused by single-point support or uneven support, and improve the stability and reliability of the entire support structure. Example

[0031] Please see Figures 1-4 Furthermore, based on Embodiment 1, the precast beam buffer support part 4 specifically includes: a spring positioning sleeve 411, which is circumferentially and equidistantly fixed on the top outer wall of the support base 311; a damping telescopic rod 413, which is set on the top of the support base 311; and a buffer support platform 414, which is set on the top of the support base 311.

[0032] The spring positioning sleeve 411 is equipped with a buffer spring 412 inside. The bottom outer wall of the buffer support platform 414 is fixedly installed with buffer pads 415 at equal intervals around the circumference. The bottom outer wall of the buffer pads 415 is fixedly installed with spring mounting positioning blocks 418. One end of the buffer spring 412 is fixedly connected to the top outer wall of the support base 311, and the other end of the buffer spring 412 is fixedly connected to the bottom outer wall of the buffer pads 415.

[0033] A buffer spring 412 is sleeved on the outer wall of the spring mounting positioning block 418. A damping telescopic rod 413 is fixedly installed on the top outer wall of the support base 311.

Buffer pads 415 are equidistantly installed on the bottom outer wall of the buffer support platform 414, and spring mounting positioning blocks 418 are installed on the bottom outer wall of the buffer pads 415, so that the other end of the buffer springs 417 is fixedly connected to the bottom outer wall of the buffer pads 415. At the same time, the buffer springs 417 are sleeved on the outer wall of the spring mounting positioning blocks 418, and the damping telescopic rod 413 is... The electric telescopic rod 419 is fixedly installed on the top outer wall of the support base 311, and its telescopic end is fixedly connected to the bottom outer wall of the buffer support platform 414. The electric telescopic rod 419 is installed on the top outer wall of the buffer support platform 414, and the support pad 416 is installed on the telescopic end of the electric telescopic rod 419. When the precast beam falls or is vibrated, the buffer spring first absorbs part of the energy through its own elastic deformation, and the damping telescopic rod further suppresses the rebound of the spring, reduces the duration and amplitude of the vibration, and protects the precast beam from damage. The electric telescopic rod can adjust the height of the support pad according to actual needs to adapt to the height requirements of different precast beams and adjustments during construction.

[0035] Working principle: When in use; Step 1: Place the support base 311 in a suitable position, so that the positioning slide column 313 is symmetrically fixedly installed on the cement ground at the bottom of the precast beam 2. Align the mounting sleeve 312 with the positioning slide column 313. Move the support base 311 onto the outer wall of the positioning slide column 313 through the mounting sleeve 312 to ensure that the support base 311 can slide flexibly on the positioning slide column 313. Fix the threaded sleeve 314 on the top outer wall of the support base 311. Screw the horizontal threaded rod 316 into the threaded sleeve 314. One end of the rod passes through the threaded sleeve 314 and extends to the bottom outer wall of the support base 311. The other end extends to the top of the threaded sleeve 314. Install the support pad 317 at the bottom end of the horizontal threaded rod 316 and fix the rotating block 315 at the top end of the rod 316.

[0036] Step 2: Install spring positioning sleeves 411 at equal intervals on the top outer wall of the support base 311, and place buffer springs 417 inside the spring positioning sleeves 411, so that one end of the buffer springs 417 is fixedly connected to the top outer wall of the support base 311.

Fix the damping telescopic rod 413 on the top outer wall of the support base 311, and fix its telescopic end to the bottom outer wall of the buffer support platform 414. Install electric telescopic rods 419 on the top outer wall of the buffer support platform 414, and install support pads 416 on the telescopic end of the electric telescopic rods 419.

[0037] Step 3: Hoist the precast beam 2 between the supporting beams and columns 1, and make the bottom outer wall of the precast beam 2 contact the top outer wall of the supporting pad 416 to complete the fixed installation of the precast beam 2 between the supporting beams and columns 1.

[0038] Step 4: If it is necessary to adjust the height of the precast beam 2, rotate the rotating block 315 to drive the horizontal threaded rod 316 to rotate in the threaded sleeve 314, so that the support pad 317 rises or falls, thereby adjusting the height of the support base 311 and the precast beam 2. The height of the precast beam 2 can also be finely adjusted by controlling the extension and retraction of the electric telescopic rod 419.

[0039] Step 5: When the precast beam 2 is subjected to vibration or impact, the buffer spring 417 will undergo elastic deformation to absorb and buffer energy. At the same time, the damping telescopic rod 413 will provide damping force to suppress excessive rebound and vibration of the buffer spring 417, ensuring stable support of the precast beam 2.
