Description

Technical Field

[0001] This invention relates to the field of building beam frame technology, specifically to an energy-absorbing and vibration-damping base for building beam frames and its construction method. Background Technology

[0002] Building beam frames are now used in building construction to provide construction workers with an operating platform for building beam construction, and also serve as a support device. They are mainly composed of components such as columns, beams, and platforms. The columns mainly play a supporting role, and the bottom of the columns is equipped with a base to increase the contact area between the columns and the ground, thereby improving the stability of the entire beam frame.

[0003] In the existing technology, in order to meet the green and environmentally friendly concept in the construction process, the improvement of concrete foundations to steel structure foundations has become the choice of most construction projects. Steel structure foundations can be prefabricated before construction, can be dismantled after construction, and are easy to assemble and disassemble, can be reused, consume less concrete materials, and can optimize carbon emissions in the construction process.

[0004] Currently, steel structure foundations are mostly constructed from steel plates and pipes through welding or bolting. These foundations are hollow internally, resulting in limited overall resistance to deformation. Vibrations generated during construction of the top platform can easily cause gradual deformation of the steel in the bottom foundation, thus affecting its service life. Therefore, this invention proposes an energy-absorbing and vibration-damping foundation for building beams and a construction method to address these problems. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-absorbing and vibration-damping base for building beams and a construction method, in order to solve the problem mentioned in the background art that the steel structure of the beam base gradually deforms due to vibration after long-term use, affecting the service life of the base.

[0013] Preferably, three I-beam legs arranged in a circular array are fixedly installed on the lower outer side of the central column. A tensioning frame is provided on the outer side of the positioning sleeve and is fixed to the upper surface of the I-beam legs. The tensioning frame is configured as a hollow triangular column structure, and the side wall of the tensioning frame has a mating notch for placing the positioning sleeve. The bottom of the positioning sleeve has an insertion notch corresponding to the corner of the tensioning frame. The positioning sleeve and the tensioning frame are inserted into each other in the vertical direction, and the bottom sealing plate abuts against the bottom of the groove of the mating notch. The mutual contact between the tensioning frame and the positioning sleeve is fixed by welding.

[0014] Preferably, the end of the I-beam support leg is fixedly connected to a foot, the upper surface of the foot is fixedly connected to a first tensioning plate, the upper part of the side corner of the tensioning frame is fixedly connected to a second tensioning plate, an adjusting rod is provided between the first tensioning plate and the corresponding second tensioning plate, and an adjusting sleeve for adjusting the length of the adjusting rod is provided in the middle of the adjusting rod. The two ends of the adjusting rod are movably connected to the first tensioning plate and the second tensioning plate respectively through pins and are tightened.

[0015] Preferably, an arc-shaped connecting plate is provided between two adjacent I-beam legs, and a perforated connecting block is provided at the end of the arc-shaped connecting plate. The perforated connecting block is located in the groove on the side of the I-beam leg. A positioning protrusion is fixedly connected to the lower part of the side corner of the tensioning frame. A screw is provided through the positioning protrusion, the I-beam leg and the perforated connecting block and is fixed by the screw.

[0016] Preferably, a fixing block is fixedly connected to the inner side of the upper corner of the tensioning frame, and a connecting protrusion corresponding to the fixing block is fixedly provided on the side of the positioning sleeve. The connecting protrusion and the fixing block are fixedly connected by bolts.

[0017] Preferably, the supporting column is a hollow steel pipe, and a plurality of stiffening plates arranged in a circular array are provided at the connection between the supporting column and the top of the plug-in cylinder. A connecting flange is provided on the outer side of the top of the supporting column.

[0018] A construction method for an energy-absorbing and vibration-damping base for building beams, as described above, specifically includes the following steps:

[0019] Step 1: Pre-assemble the positioning sleeve and tensioning bracket. Insert the positioning sleeve and tensioning bracket into each other and weld them at the joint. Then, use bolts to reinforce the connecting protrusion and the fixing block.

[0020] Step 2: Install the tensioning bracket and positioning sleeve. Place the tensioning bracket on the outside of the central column and ensure that the central column passes through the round hole in the middle of the bottom sealing plate from bottom to top. Then, fix the perforated connecting block, I-beam support leg and positioning protrusion together with the screw. Use the adjusting rod to tighten the second tensioning plate with the first tensioning plate.

[0021] Step 3: Install the plug-in sleeve. Insert the plug-in sleeve into the inner cavity of the positioning sleeve from top to bottom until the bottom of the plug-in sleeve abuts against the annular pad. Then, pour concrete into the inner cavity of the plug-in sleeve through the pouring interface. The concrete can fill the inner cavity of the through hole and the inner cavity of the leakage gap. After the concrete solidifies, the plug-in sleeve and the positioning sleeve can remain stable. Moreover, the concrete fills the inside of the plug-in sleeve, which can reduce the possibility of deformation of the plug-in sleeve.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention features a positioning sleeve fitted around the outer side of a central column. The positioning sleeve has a bottom sealing plate and an annular pad at its bottom. A connector is inserted into the inner cavity of the positioning sleeve from top to bottom, with the bottom of the connector abutting against the annular pad. A central column is fixed to the inner wall of the top of the connector. A pad is placed between the lower end of the central column and the upper end of the central column. Through holes and leakage notches are respectively provided on the surface of the central column and the connector. After the connector is inserted into the inner cavity of the positioning sleeve, concrete is poured from the top of the connector into its inner cavity. After the concrete solidifies, it fills the inside of the connector, reducing the degree of deformation caused by vibration and thus improving its service life. During long-term use, if the concrete inside the connector gradually cracks and breaks due to absorbing vibration energy, it can be re-poured, thereby increasing the reusability of the device.

[0034] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0035] Please see Figures 1 to 6 The present invention provides a technical solution:

[0036] Example 1: An energy-absorbing and vibration-damping base for building beams includes: a central column 2, a positioning sleeve 4, a plug-in sleeve 5, and a supporting column 6.

[0037] Specifically, a through hole 21 is provided on the surface of the central column 2, such as... Figure 3 As shown, when the concrete grout covers the outside of the central column 2, the grout can enter the inner cavity of the through hole 21. After the concrete grout solidifies, it can maintain a more stable connection with the central column 2.

[0038] Secondly, the positioning sleeve 4 is sleeved on the outside of the central column 2. The bottom of the inner cavity of the positioning sleeve 4 is fixedly provided with a bottom sealing plate 41, and a round hole for the central column 2 to pass through is opened in the middle of the bottom sealing plate 41. A sealing layer is provided at the joint between the bottom sealing plate 41 and the central column 2 to prevent concrete slurry leakage. An annular pad 42 is provided on the upper surface of the bottom sealing plate 41.

[0039] Furthermore, the insertion sleeve 5 is inserted into the inner cavity of the positioning sleeve 4 from top to bottom and is adapted to the positioning sleeve 4. Therefore, the outer side wall of the insertion sleeve 5 and the inner side wall of the positioning sleeve 4 can fit together, reducing the possibility of concrete slurry leakage. The insertion sleeve 5 is set as a hollow polygonal column structure with an opening at the bottom. The side wall of the insertion sleeve 5 is provided with a leakage notch 51, such as... Figure 6 As shown, combined with Figure 2It can be seen that after the insertion sleeve 5 and the positioning sleeve 4 are inserted into each other, concrete grout is poured into the inner cavity of the insertion sleeve 5. The concrete grout can fill the inner cavity of the insertion sleeve 5, the inner cavity of the leakage gap 51, and the inner cavity of the through hole 21. After the grout solidifies, the concrete can fix the insertion sleeve 5, the positioning sleeve 4, and the central column 2, and fill and support the inner wall of the insertion sleeve 5, reducing the possibility of deformation of the insertion sleeve 5 due to vibration. In addition, when the concrete absorbs vibration for a long time and causes itself to break, it can be repaired by re-pouring concrete grout, thereby improving the service life of the entire steel structure of this device. A central column 52 is fixedly connected to the top inner wall of the connector 5, and the central column 52 corresponds to the central column 2. A pad 53 is provided between the central column 52 and the central column 2. The pad 53 and the annular pad 42 make the connector 5 and the positioning sleeve 4 not completely fixed relative to each other when they are inserted and positioned in the vertical direction, but have a certain amount of relative sliding displacement. The relative displacement is consistent with the deformation degree of the annular pad 42 and the pad 53. Therefore, when the device is subjected to vertical vibration, the vibration can be partially absorbed by the annular pad 42 and the pad 53, thereby further improving the service life of the device.

[0040] In addition, the support column 6 is fixed to the top of the plug-in cylinder 5 and is in the same straight line as the central column 2. As the main support component of the entire beam frame, the support column 6 corresponds to the central column 2 and can transfer most of the weight to the central column 2. The other part of the weight is applied to the solidified concrete inside the plug-in cylinder 5, thereby ensuring the stability of the support column 6.

[0041] In Example 2, based on Example 1, to facilitate the filling of grout into the inner cavity of the insertion cylinder 5, both the positioning sleeve 4 and the insertion cylinder 5 of this application are designed with a regular hexagonal cross-section. This prevents relative rotation between the insertion cylinder 5 and the positioning sleeve 4. A casting interface 54 is fixedly provided on the top side of the insertion cylinder 5, and the casting interface 54 communicates with the inner cavity of the insertion cylinder 5. A ball valve is provided in the middle of the casting interface 54. Figure 6 As shown, the pouring interface 54 is designed to facilitate the filling of concrete slurry into the inner cavity of the plug-in cylinder 5 by the external concrete slurry pipe, and the ball valve is designed to prevent concrete slurry leakage.

[0042] In Example 3, based on Example 2, in order to improve the connection strength between the positioning sleeve 4, the plug-in sleeve 5, and the central column 2, the annular pad 42 and the pad block 53 of this application are both made of hard rubber material. The annular pad 42 and the pad block 53 themselves have a certain degree of elastic deformation to absorb the vertical vibration of the device. Multiple leakage gaps 51 are provided and distributed in a ring array around the plug-in sleeve 5. After the concrete grout in the inner cavity of the plug-in sleeve 5 flows into the inner cavity of the leakage gap 51, it can fit against the inner wall of the positioning sleeve 4, thereby improving the stability of the connection between the plug-in sleeve 5 and the positioning sleeve 4 after the grout solidifies. Multiple through holes 21 are provided and at least two rows are provided in the vertical direction. The multiple through holes 21 are distributed in a ring array around the central column 2 to improve the connection strength between the grout and the central column 2 after solidification.

[0043] In Example 4, based on Example 3, in order to splice and fix the positioning sleeve 4 and the tensioning frame 3, this application also has three I-beam support legs 1 fixedly installed in a circular array on the outer side of the lower end of the central column 2, such as... Figure 3 As shown, the I-beam support leg 1 is used to support the entire device and prevent it from tilting. The I-beam support leg 1 is placed below the ground, which also prevents the entire device from rotating. A tensioning frame 3 is provided on the outer side of the positioning sleeve 4, and the tensioning frame 3 is fixed to the upper surface of the I-beam support leg 1. The tensioning frame 3 is a hollow triangular column structure, and its side wall has a mating notch 34 for placing the positioning sleeve 4. The bottom of the positioning sleeve 4 has an insertion notch 43 corresponding to the corner of the tensioning frame 3. The positioning sleeve 4 and the tensioning frame 3 are vertically interlocked, and the bottom sealing plate 41 abuts against the bottom of the groove of the mating notch 34. The mating joint between the tensioning frame 3 and the positioning sleeve 4 is fixed by welding. Figure 4 and Figure 5 As shown, when the positioning sleeve 4 is spliced ​​with the tensioning frame 3 from top to bottom, the positioning sleeve 4 can be inserted into the inner cavity of the mating notch 34, and the tensioning frame 3 can be aligned with the insertion notch 43. Then, the joint between the two is welded to ensure the stability of the connection between them.

[0044] In Example 5, based on Example 4, in order to tighten and position the tensioning frame 3 and the positioning sleeve 4, this application further includes a support leg 11 fixedly connected to the end of the I-beam support leg 1, a first tensioning plate 12 fixedly connected to the upper surface of the support leg 11, a second tensioning plate 36 fixedly connected to the upper part of the side corner of the tensioning frame 3, an adjusting rod 31 provided between the first tensioning plate 12 and the corresponding second tensioning plate 36, and an adjusting sleeve 32 for adjusting the length of the adjusting rod 31 provided in the middle of the adjusting rod 31, the two ends of the adjusting rod 31 being movably connected to the first tensioning plate 12 and the second tensioning plate 36 respectively via pins and tightened accordingly. Figure 3 and Figure 4As shown, by rotating the adjusting sleeve 32 to adjust the length of the adjusting rod 31, the corner of the tensioning frame 3 can be tightened between the corresponding I-beam support leg 1. When the positioning sleeve 4 tilts, the adjusting rod 31 can transmit the force to the I-beam support leg 1 and tighten and position the positioning sleeve 4, thereby improving the stability of the positioning sleeve 4.

[0045] In Example 6, based on Example 5, to further improve the stability of the tensioning frame 3, this application also includes an arc-shaped connecting plate 13 between two adjacent I-beam legs 1. The end of the arc-shaped connecting plate 13 is provided with a perforated connecting block 14, which is located in a groove on the side of the I-beam leg 1. A positioning protrusion 33 is fixedly connected to the lower part of the side corner of the tensioning frame 3. A screw is provided through the positioning protrusion 33, the I-beam leg 1, and the perforated connecting block 14 and is fixed by the screw. The arc-shaped connecting plate 13 can further strengthen the stability of the I-beam leg 1. In addition, after the positioning protrusion 33 is fixed to the I-beam leg 1, the tensioning frame 3 can be further strengthened, thereby improving the stability of the tensioning frame 3 installation.

[0046] In embodiment seven, based on embodiment six, to further enhance the connection between the positioning sleeve 4 and the tensioning frame 3, this application also includes a fixing block 35 fixedly connected to the inner side of the upper corner of the tensioning frame 3, and a connecting protrusion 44 corresponding to the fixing block 35 fixedly provided on the side of the positioning sleeve 4. The connecting protrusion 44 and the fixing block 35 are fixedly connected by bolts. Figure 4 and Figure 5 As shown, after the connecting protrusion 44 is fixed to the fixing block 35, the stress at the welded connection between the positioning sleeve 4 and the tensioning bracket 3 can be reduced, thereby preventing the positioning sleeve 4 from detaching from the tensioning bracket 3.

[0047] In Example 8, based on Example 7, the supporting column 6 of this application is a hollow steel pipe. Multiple stiffening plates arranged in a circular array are provided at the connection between the supporting column 6 and the top of the plug-in cylinder 5. A connecting flange 61 is provided on the outer side of the top of the supporting column 6. The connecting flange 61 facilitates the fixing of other steel pipes to the upper end of the supporting column 6, so as to change the height of the entire column. The supporting column 6 on the base of this device is relatively short, which is intended to reduce the height of the entire device and make prefabrication and pre-installation more convenient.

[0048] This invention also discloses a construction method for the above-mentioned energy-absorbing and vibration-damping base for building beams, specifically including the following steps:

[0049] Step 1: Pre-assemble the positioning sleeve 4 and the tensioning bracket 3. Insert the positioning sleeve 4 and the tensioning bracket 3 into each other and weld them at the joint. Then use bolts to reinforce the connecting protrusion 44 and the fixing block 35.

[0050] Step 2: Install the tensioning bracket 3 and the positioning sleeve 4. Fit the tensioning bracket 3 on the outside of the central column 2 and ensure that the central column 2 passes through the round hole in the middle of the bottom sealing plate 41 from bottom to top. Then, fix the perforated connecting block 14, the I-beam support leg 1 and the positioning protrusion 33 together with the screw. Then, use the adjusting rod 31 to tighten the second tensioning plate 36 with the first tensioning plate 12.

[0051] Step 3: Install the plug-in sleeve 5. Insert the plug-in sleeve 5 into the inner cavity of the positioning sleeve 4 from top to bottom until the bottom of the plug-in sleeve 5 abuts against the annular pad 42. Then, pour concrete into the inner cavity of the plug-in sleeve 5 through the pouring interface 54. The concrete can fill the inner cavity of the through hole 21 and the inner cavity of the leakage gap 51. After the concrete solidifies, the plug-in sleeve 5 and the positioning sleeve 4 can remain stable. The concrete fills the inside of the plug-in sleeve 5, which can reduce the possibility of deformation of the plug-in sleeve 5.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Insert the plug-in sleeve (5) into the inner cavity of the positioning sleeve (4) from top to bottom until the bottom of the plug-in sleeve (5) touches the annular pad (42). Then pour concrete into the inner cavity of the plug-in sleeve (5) through the pouring interface (54). The concrete can fill the inner cavity of the through hole (21) and the inner cavity of the leakage gap (51). After the concrete solidifies, the plug-in sleeve (5) and the positioning sleeve (4) can remain stable. The concrete fills the inside of the plug-in sleeve (5), which can reduce the possibility of deformation of the plug-in sleeve (5).
