Description

Technical Field

[0001] The invention belongs to the field of auxiliary tools for connecting concrete molds, and particularly relates to a connecting mechanism for special-shaped column formwork and a beam-column connecting mechanism. Background Art

[0002] The fixed connection node between the inclined surface of a special-shaped column and a cross beam is applicable to fair-faced concrete structures. For example, high-speed railway bridges are cast with fair-faced concrete, and the surface of the support column is smooth after the formwork is removed after casting. Before pouring, the main components of the vertical column and cross beam steel bars are connected together. If the vertical column is poured first and then the cross beam is poured, after the formwork is removed, the strength between the cross beam and the vertical column (the fixed connection node between the inclined surface of the special-shaped column and the cross beam) is insufficient, and pouring joints are likely to occur. Moreover, when casting and forming a special-shaped column, if tie rods are used for the formwork of the inclined surface and the straight surface, the nuts on the inclined surface cannot all be pressed against the formwork, resulting in displacement of the formwork on the inclined surface, which will also affect the forming and strength of the cross beam and the vertical column. Therefore, we propose a connecting mechanism for special-shaped column formwork and a beam-column connecting mechanism. Summary of the Invention

[0003] The purpose of the invention is to provide a connecting mechanism for special-shaped column formwork and a beam-column connecting mechanism to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the invention provides the following technical solution: A connecting mechanism for special-shaped column formwork includes a special-shaped steel frame, and a top plate and a bottom plate respectively attached to the top and bottom of the special-shaped steel frame. Moreover, a straight side plate and an inclined formwork are respectively attached to the straight side and the inclined side of the special-shaped steel frame. The top plate and the bottom plate are fixedly assembled at the top and bottom of the special-shaped steel frame through tie rods, and both the straight side plate and the inclined formwork are located between the top plate and the bottom plate.

[0005] Preferably, the upper end surfaces of the straight side plate and the inclined formwork are both in contact with the bottom surface of the top plate, and the lower end surfaces of the straight side plate and the inclined formwork are both in contact with the top surface of the bottom plate. A plurality of extending bosses are fixedly installed on the end surface of the inclined formwork away from the straight side plate, and the end surface of the extending boss away from the special-shaped steel frame is parallel to the straight side plate. Each extending boss and the straight side plate are fixedly assembled through a tie rod. Clamping the straight side plate and the inclined formwork between the top plate and the bottom plate can avoid the situation of the inclined formwork tilting or displacing when fixing the straight side plate and the inclined formwork.

[0006] A beam-column connection mechanism comprises a special-shaped column formwork connection mechanism as described above, wherein the inclined formwork comprises two inclined side plates, and the two inclined side plates are symmetrically distributed, and a crossbeam formwork is fixedly installed on one end face of each inclined side plate away from the special-shaped steel frame, and the two crossbeam formworks are assembled to form a crossbeam casting cavity, and the crossbeam casting cavity is communicated with the special-shaped steel frame, and the crossbeam casting cavity is used for casting concrete.

[0007] Preferably, the upper end surface of the beam casting cavity is open, and a pressure cover mechanism for closing and shaping is provided at the upper end of the beam casting cavity. The end surfaces of the two beam formworks that are away from each other are provided with a vibration mechanism, and a driving mechanism is provided between the two vibration mechanisms and the pressure cover mechanism. The open setting makes it convenient for the staff to add concrete to the interior of the beam casting cavity.

[0008] Preferably, the cover pressing mechanism comprises a limit block fixedly mounted on the upper end surface of the beam template and arranged close to the inclined side plate, a cover plate is installed on the upper end of the two beam templates, and a T-shaped cavity is opened inside the cover plate close to one end of the special-shaped steel frame, and two symmetrically distributed latches are slidably mounted on one end of the cover plate close to the special-shaped steel frame, and one end of each latch extending into the T-shaped cavity is fixedly sleeved with a collar, and a first tension spring is fixedly mounted between the ends of the two collars away from each other and the T-shaped cavity, and the latch extends out of the T-shaped cavity. One end is movably engaged with the limit block, the pins are distributed in the longitudinal cavity of the T-shaped cavity, and a slider is slidably installed in the transverse cavity of the T-shaped cavity, a pull rope is fixedly connected between one end of each pin extending into the T-shaped cavity and the slider, and two guide columns for guiding the pull rope are also fixedly installed inside the T-shaped cavity, and a pull rod sliding through the covering plate is fixedly installed at one end of the slider away from the pull rope. By arranging two symmetrically distributed pins inside the T-shaped cavity, it is convenient for staff to install and disassemble the covering plate.

[0009] Preferably, the latch is disposed through the limit block, and the latch directly penetrates the limit block after assembly is completed, so as to prevent the spilled concrete from clogging the through hole of the limit block during the casting process.

[0010] Preferably, the vibration mechanism includes a connecting frame body which is fixedly installed on the side of the crossbeam formwork away from the crossbeam casting cavity. Two limit clamping plates are fixedly installed inside the connecting frame body, and a number of drive gears are rotatably installed between the two limit clamping plates and are linearly and equidistantly distributed. A drive shaft is also rotatably installed inside the connecting frame body, and a driving gear is fixedly sleeved on the outer surface of the drive shaft. A transmission chain is arranged between a number of the drive gears and the driving gear. A knocking rod is movably installed inside each drive gear, and the knocking rod axially penetrates through the connecting frame body. A chuck is fixedly sleeved at one end of the knocking rod extending out of the connecting frame body, and a second tension spring is fixedly arranged between the chuck and the connecting frame body. A turntable is fixedly sleeved on the outer surface of each knocking rod, and the turntable is located inside the connecting frame body. A push rod is fixedly installed at one end of each drive gear close to the chuck, and a number of right-angled trapezoidal lifting blocks are fixedly installed at one end of the turntable close to the push rod and are circumferentially and equidistantly distributed. When the push rod rotates with the drive gear, the turntable and the knocking rod can be pushed out of the connecting frame body through the inclined surface of the right-angled trapezoidal lifting block.

[0011] Preferably, the driving mechanism includes a driving motor and a gear differential located above the cover plate. The driving motor and the gear differential are fixed through an assembly plate. The output end of the driving motor is in transmission assembly with the input end of the gear differential. The gear differential has two output ends, and synchronous gears are fixedly sleeved at both ends of the two output ends of the gear differential and at the end of the drive shaft extending out of the connecting frame body. The two output ends of the gear differential are arranged in parallel with the drive shaft, and a synchronous belt is arranged in transmission between two synchronous gears on the same side. A pressing component is arranged between the driving motor and the cover plate. The driving motor rotates its two output ends through the gear differential, and during the rotation of the two output ends, the two drive shafts can be driven to rotate through the action of the synchronous gears and the synchronous belt.

[0012] Preferably, the pressing component includes a movable plate fixedly arranged at the bottom of the driving motor and the gear differential. One end of the movable plate close to the special-shaped steel framework is movably hinged to the cover plate, and a pressing spring is fixedly installed between the movable plate and the cover plate. The pressing spring elastically supports between the cover plate and the movable plate to make the synchronous belt in a tight state. At the same time, the reaction elastic force generated by the compressed pressing spring can tightly cover the cover plate on the upper ends of the two crossbeam formworks.

[0013] Preferably, the connecting frame body is inclined and is parallel to the inclined side plate, ensuring that the knocking rod inside the connecting frame body can vibrate the concrete at the inclined part of the crossbeam casting cavity.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In the present invention, the straight side plate and the inclined template are clamped between the top plate and the bottom plate, and then the top plate and the bottom plate, as well as the straight side plate and the inclined template, are fixed by tie rods. Since the upper and lower end faces of the inclined template are restricted by the top plate and the bottom plate, it is possible to ensure that the inclined template does not tilt or displace during the fixing process;

[0016] In the present invention, a cross beam template is designed on the side of the inclined template to form a cross beam pouring cavity, realizing the integral pouring and molding of the cross beam and the column. After pouring is completed, the vibration mechanism is triggered by the driving mechanism to vibrate the connection point between the cross beam and the column, promoting the bubbles inside the concrete at this part to burst and discharge, thereby ensuring the strength of the connection point after the concrete solidifies.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 , a connecting mechanism for special-shaped column formwork, including a special-shaped steel framework 1, a top plate 2 and a bottom plate 3 respectively attached to the top and bottom of the special-shaped steel framework 1, and a straight side plate 4 and an inclined formwork are respectively attached to the straight side and the inclined side of the special-shaped steel framework 1. The top plate 2 and the bottom plate 3 are fixedly assembled at the top and bottom of the special-shaped steel framework 1 through tie rods, and both the straight side plate 4 and the inclined formwork are located between the top plate 2 and the bottom plate 3.

[0028] The upper end surfaces of the straight side plate 4 and the inclined formwork are both in contact with the bottom surface of the top plate 2, and the lower end surfaces of the straight side plate 4 and the inclined formwork are both in contact with the top surface of the bottom plate 3. A plurality of extension bosses 6 are fixedly installed on the end surface of the inclined formwork away from the straight side plate 4, and the end surface of the extension boss 6 away from the special-shaped steel framework 1 is parallel to the straight side plate 4. Each extension boss 6 and the straight side plate 4 are fixedly assembled through tie rods.

[0029] The working principle of preventing the inclined formwork from tilting or displacing when fixing the special-shaped column formwork:

[0030] When assembling the formwork for the special-shaped steel framework 1 of the special-shaped column, the straight side plate 4 and the inclined formwork should be clamped between the top plate 2 and the bottom plate 3. First, fix the top plate 2 and the bottom plate 3 with tie bolts, and then fix the straight side plate 4 and the inclined formwork with tie bolts. Since the top and bottom ends of the straight side plate 4 and the inclined formwork are restricted by the top plate 2 and the bottom plate 3, when fixing the straight side plate 4 and the inclined formwork with tie bolts, the situation of the inclined formwork tilting or displacing can be avoided, and the stability and accuracy of the formwork fixation can also be ensured.

[0031] Please refer to Figures 2 - 8 , a beam-column connection mechanism, including the above-mentioned special-shaped column formwork connection mechanism. The inclined formwork includes two inclined side plates 5, and the two inclined side plates 5 are symmetrically distributed. A crossbeam formwork 7 is fixedly installed on the end face of each inclined side plate 5 away from the special-shaped steel framework 1. The two crossbeam formworks 7 are assembled to form a crossbeam pouring cavity, and the crossbeam pouring cavity communicates with the special-shaped steel framework 1. The crossbeam pouring cavity is used for pouring concrete.

[0032] The upper end face of the crossbeam pouring cavity is open, and a pressing cover mechanism 8 for closing and shaping is arranged at the upper end of the crossbeam pouring cavity. Vibration mechanisms 9 are arranged on the end faces of the two crossbeam formworks 7 away from each other, and a driving mechanism 10 is arranged between the two vibration mechanisms 9 and the pressing cover mechanism 8. The open setting of the upper end face of the crossbeam pouring cavity facilitates the staff to add concrete into the crossbeam pouring cavity.

[0033] The pressing cover mechanism 8 includes a limit block 18 fixedly installed on the upper end face of the crossbeam formwork 7 and close to the inclined side plate 5. A cover plate 12 is installed at the upper end of the two crossbeam formworks 7, and a T-shaped cavity 19 is opened inside the end of the cover plate 12 close to the special-shaped steel framework 1. Two symmetrically distributed pins 21 are slidably installed at the end of the cover plate 12 close to the special-shaped steel framework 1. A collar 22 is fixedly sleeved at one end of each pin 21 extending into the T-shaped cavity 19, and a first tension spring 23 is fixedly installed between the ends of the two collars 22 away from each other and the T-shaped cavity 19. The end of the pin 21 extending out of the T-shaped cavity 19 is movably fitted with the limit block 18. The pins 21 are distributed in the longitudinal cavity of the T-shaped cavity 19, and a slider 24 is slidably installed in the transverse cavity of the T-shaped cavity 19. A pull rope 26 is fixedly connected between the end of each pin 21 extending into the T-shaped cavity 19 and the slider 24. Two guide posts 25 for guiding the pull ropes 26 are also fixedly installed inside the T-shaped cavity 19. A pull rod 20 slidably penetrating through the cover plate 12 is fixedly installed at the end of the slider 24 away from the pull rope 26. By arranging two symmetrically distributed pins 21 inside the T-shaped cavity 19, it is convenient for the staff to install and disassemble the cover plate 12.

[0034] The bolt 21 is arranged through the limit block 18. After assembly, the bolt 21 directly penetrates through the limit block 18 to prevent the spilled concrete from blocking the through hole of the limit block 18 during the casting process.

[0035] The vibration mechanism 9 includes a connecting frame body 13 which is fixedly installed on the side of the crossbeam formwork 7 away from the crossbeam casting cavity. Two limit clamping plates 35 are fixedly installed inside the connecting frame body 13, and a number of transmission gears 29 arranged at equal intervals in a straight line are rotatably installed between the two limit clamping plates 35. A driving shaft 27 is also rotatably installed inside the connecting frame body 13, and a driving gear is fixedly sleeved on the outer surface of the driving shaft 27. A transmission chain 30 is arranged for transmission between the number of transmission gears 29 and the driving gear. A knocking rod 37 is movably installed inside each transmission gear 29, and the knocking rod 37 axially penetrates through the connecting frame body 13. One end of the knocking rod 37 extending out of the connecting frame body 13 is fixedly sleeved with a chuck 31, and a second tension spring 32 is fixedly arranged between the chuck 31 and the connecting frame body 13. A turntable 33 is fixedly sleeved on the outer surface of each knocking rod 37, and the turntable 33 is located inside the connecting frame body 13. A push rod 36 is fixedly installed at one end of each transmission gear 29 close to the chuck 31, and a number of right-angled trapezoidal lifting blocks 34 arranged at equal intervals in a circle are fixedly installed at one end of the turntable 33 close to the push rod 36. When the push rod 36 rotates following the transmission gear 29, it can push the turntable 33 and the knocking rod 37 towards the outside of the connecting frame body 13 through the inclined surface of the right-angled trapezoidal lifting block 34.

[0036] The driving mechanism 10 includes a driving motor 14 and a gear differential 15 located above the cover plate 12, and the driving motor 14 and the gear differential 15 are fixed through an assembly plate. The output end of the driving motor 14 is in transmission assembly with the input end of the gear differential 15. The gear differential 15 has two output ends, and synchronous gears are fixedly sleeved at both ends of the two output ends of the gear differential 15 and at the end of the driving shaft 27 extending out of the connecting frame body 13. The two output ends of the gear differential 15 are arranged in parallel with the driving shaft 27, and a synchronous belt 28 is arranged for transmission between the two synchronous gears on the same side. A pressing component 11 is arranged between the driving motor 14 and the cover plate 12. The driving motor 14 rotates its two output ends through the gear differential 15. During the rotation of the two output ends, the two driving shafts 27 can be driven to rotate through the action of the synchronous gears and the synchronous belt 28.

[0037] The pressure - applying assembly 11 includes a movable plate 16 fixedly arranged at the bottom of the driving motor 14 and the gear differential 15. One end of the movable plate 16 close to the special - shaped steel framework 1 is movably hinged to the covering plate 12. A pressure - applying spring 17 is fixedly installed between the movable plate 16 and the covering plate 12. The pressure - applying spring 17 elastically supports between the covering plate 12 and the movable plate 16, which can keep the synchronous toothed belt 28 in a taut state. At the same time, the reaction elastic force generated by the compressed pressure - applying spring 17 will also tightly cover the covering plate 12 on the upper ends of the two cross - beam templates 7.

[0038] The connecting frame body 13 is inclined, and the connecting frame body 13 is parallel to the inclined side plate 5, ensuring that the knocking rod 37 inside the connecting frame body 13 can vibrate the concrete at the inclined part of the cross - beam pouring cavity.

[0039] In this embodiment: The cross - beam template 7 is wrapped outside the cross - beam steel member. By pouring concrete into the cross - beam pouring cavity, the column and the cross - beam can be integrally poured and formed. After the pouring is completed, the staff assembles the covering plate 12 to the upper parts of the two cross - beam templates 7. By pulling the slider 24 with the pull rod 20, the pull rope 26 pulls the bolt 21 back into the inside of the covering plate 12. Then, after the covering plate 12 is embedded on the tops of the two cross - beam templates 7, the pull rod 20 is released. Under the action of the first tension spring 23, the two bolts 21 can be reset, and the bolts 21 are embedded into the limit blocks 18, thus completing the hinged assembly of the covering plate 12 on the upper parts of the two cross - beam templates 7.

[0040] After the assembly is completed, the staff keeps the covering plate 12 covering the upper parts of the two cross - beam templates 7, and respectively slews the two synchronous toothed belts 28 between two groups of synchronous gears. During the assembly process, the movable plate 16 should be pressed downward to compress the pressure - applying spring 17. After the synchronous toothed belt 28 is assembled, the movable plate 16 is released. Under the reaction elastic force of the pressure - applying spring 17, the tension state of the two synchronous toothed belts 28 can be ensured, and the reaction elastic force can also be applied to the covering plate 12, making the covering plate 12 fit tightly with the upper end surface of the cross - beam template 7.

[0041] After the cover plate 12 and the synchronous toothed belts 28 are installed, the staff starts the drive motor 14. Under the action of the gear differential 15 and the two synchronous toothed belts 28, the two drive shafts 27 are driven to rotate. The drive shafts 27 can drive a number of transmission gears 29 to rotate through the transmission chain 30. During the rotation of each transmission gear 29, it can push against the inclined surfaces of a number of right trapezoidal lifting blocks 34 through the push rod 36. During each pushing process against the inclined surfaces of the right trapezoidal lifting blocks 34, the knocking rod 37 can move a certain distance towards the outside of the connecting frame 13. When the push rod 36 slides to the right-angle side of the right trapezoidal lifting block 34, the knocking rod 37 will quickly reset under the action of the second tension spring 32, so as to realize knocking on the side wall of the crossbeam formwork 7 by the knocking rod 37. The vibration force generated by the knocking is transmitted to the inside of the crossbeam pouring cavity, causing the bubbles in the still-unset concrete in the crossbeam pouring cavity to burst and disappear, thereby improving the strength of the concrete at the connection point between the column and the crossbeam.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
