Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering construction, and particularly relates to a vertical vibration damping device for a high and large formwork support frame. Background Art

[0002] The prior art such as a construction engineering scaffold disclosed in CN217353424U includes vertical poles, horizontal bars and diagonal braces. A connecting plate is provided on the vertical pole. Buckle joints are provided at the connecting ends of the horizontal bar and the diagonal brace. The buckle joints are fixed on the connecting plate through pins. An anti - detachment structure is provided at the bottom of the pin. The anti - detachment structure includes a limiting rotating plate. A through shaft hole is provided on the top surface of the limiting rotating plate. A rotating shaft is provided in the shaft hole. The upper end of the rotating shaft is connected to the bottom of the pin. An anti - detachment cap is provided at the lower end of the rotating shaft. The anti - detachment cap is larger than the aperture of the shaft hole. It is a form of formwork support frame with a common disc - type jack structure in the existing formwork system. However, the anti - vibration of the entire formwork support system is not considered in this formwork support frame structure, so that the entire structural system cannot meet the safety and stability requirements of construction. The high formwork support system, as the main temporary facility in construction, plays a crucial role in the safety of the entire construction process. In the prior art, insufficient consideration is given to the vibration damping measures for the high formwork support frame, resulting in frequent collapse accidents of the high formwork support frame in recent years. The collapse of the high formwork support frame mainly occurs during the concrete pouring stage. The main reason is the action of dynamic loads generated by the formwork support frame when bearing the concrete pouring. The dynamic loads greatly weaken the safety and reliability of the formwork support frame. The dynamic loads come from the pouring of concrete, the vibration of concrete, the placement of large - scale concrete distributors, and the reciprocating movement of the concrete pump pipe during the pumping of concrete, etc.

[0003] CN102031868A discloses a construction formwork support frame, including vertical poles, horizontal bars, jacks and connecting buckles. Among them, the horizontal bar and the vertical pole are connected through the connecting buckle to form the overall formwork support frame. An adjustable jack is provided at the top of the vertical pole. The adjustable jack is fixed on the vertical pole through a limiting ring and becomes a part of the vertical pole. The horizontal bar is divided into a fixed - length horizontal bar and an adjustable horizontal bar. The adjustable horizontal bar is connected to the vertical pole and the fixed - length horizontal bar on the side of the formwork support frame through the connecting buckle to form the overall structure of the construction formwork support frame. When adopting the above - mentioned formwork support system, especially when the concrete pump pipe conveys concrete, a horizontal step load is generated and transmitted to the formwork support frame through the friction force between components. At the same time, as the concrete is poured, the mass at the top of the formwork support frame gradually increases and is in the form of eccentric load. The natural vibration frequency of the formwork support frame changes. When the frequency of the external excitation load is close to the natural vibration frequency of the formwork support frame, a resonance effect occurs. At this time, the amplitude of the formwork support frame increases significantly, and the formwork support frame is extremely prone to damage and collapse at this time.

[0004] In summary, in view of the safety hazard of system collapse caused by insufficient consideration of vibration reduction in the formwork support system in the prior art, it is proposed to add a special vibration reduction device at the commonly used adjustable jack and vertical rod to achieve vibration reduction and energy dissipation of the horizontal dynamic load transmitted from the upper part, reduce the dynamic response of the high formwork support under the horizontal dynamic load during concrete pouring, and improve the safety of the formwork support.

Screw the U-shaped support 1 into the threaded sleeve 2-1. Remove the tightening bolt 2-5-1-4 in the threaded hole of the threaded pipe 2-5-1 on the spring support adjusting pipe 2-2. Turn the multi-functional wrench nut 2-2 to adjust the length of the overhanging section of the U-shaped support 1 to the design elevation. This is state one. 11. Remove the side tightening screw 2-2-7 of the wrench nut 2-2-1. Tighten the tightening bolt 2-5-1-4 in the threaded hole of the threaded pipe 2-5-1 on the spring support adjusting pipe 2-5 to fix the upper threaded pipe 2-5-1, the threaded sleeve 2-1 and the vertical rod. Referring to the scale (2-1-3) on the side of the threaded sleeve 2-1, turn the multi-functional wrench nut 2-2 to press down the damping spring 2-4 to the preset spring compression position. 12. Remove the tightening bolt 2-5-1-4 in the threaded hole of the threaded pipe 2-5-1 on the spring support adjusting pipe 2-5. At this time, the multi-functional wrench nut 2-2, the threaded sleeve 2-1 and the U-shaped support 1 move upward under the action of the spring, and the top plate of the U-shaped support 1 exceeds the preset compression amount of the design elevation. 13. Remove the tightening bolt 3-2-9 in the threaded hole 2-5-2-1 of the lower threaded pipe 2-5-2 of the spring support adjusting pipe 2-5, and start pouring the floor concrete. This is state two.

[0042] II. After the concrete is poured, since the preset compression amount of the damping spring 2-4 takes into account the amplification factor, after the concrete is poured, the actual compression amount of the damping spring 2-4 is less than the preset compression amount. At this time, the formwork elevation is greater than the design elevation, the inner step of the threaded sleeve 2-1 still does not contact the vertical rod anti-catching part 5 at the top of the vertical rod, and the U-shaped support 1 is not fully retracted. This is state three.

[0043] The operator hooks the pull switch 3-1 at the bottom of the scaffold with a hook and pulls the pull switch 3-1 to make the temporary ferrule 3 open and not fall off. The spring support adjusting pipe 2-5 automatically drops due to gravity, so that all parts above the transition force transmission part 4 fall, making the step formed by the large and small hole sections of the threaded sleeve 2-1 contact the vertical rod anti-catching part 5 at the top of the vertical rod, and the damping spring 2-4 returns to the relaxed state, realizing the elevation return. This is state four.

[0044] When the device is installed, after the inner step of the threaded sleeve 2-1 contacts the vertical rod anti-catching part 5, the exposed length of the screw rod is adjusted through the multi-functional wrench nut 2-2, so that the top of the U-shaped plate reaches the design elevation; then remove the side tightening screw of the wrench nut 2-2-1, disconnect the connection between the wrench nut 2-2-1 and the threaded sleeve 2-1, and turn the multi-functional wrench nut 2-2 to compress the spring, and the preset compression amount of the damping spring 2-4 can be adjusted. The preset compression amount can be calculated according to different plate thicknesses and considering the amplification factor. The accurate positioning of the preloading position is realized through the scale (2-1-3) groove on the side wall of the threaded sleeve 2-1. At this time, the top plate of the U-shaped support 1 is higher than the design elevation, and the height difference is the preset compression amount of the damping spring 2-4. At this time, pouring concrete can reduce the vertical kinetic energy through the elastic action of the spring.

[0045] The process of presetting the compression amount of the spring in the present invention is as follows: The load g1 acting on a single vertical rod of the support frame includes the self-weights of components such as formwork and small joists; the load g2 acting on a single vertical rod of the support frame includes the self-weights of steel bars and concrete, as well as the self-weights of components such as steel members and in-situ concrete; the variable load q1 on a single vertical rod of the support frame includes the construction workers, construction equipment, and the stacking load of concrete materials exceeding the thickness of the poured component acting on the formwork surface at the top of the support frame structure; considering the dynamic amplification factor of 1.2, the total load G borne on a single vertical rod is: G = 1.2×[1.3×(g 1 +g 2 ) + 1.5×q 1

[0046] According to the spring elastic coefficient k, considering the spring elastic redundancy amplification factor of 1.2, the preset compression amount L of the spring can be obtained as: L = 1.2×G / k

[0047] In order to ensure that the inner step of the threaded sleeve 2-1 does not collide with the vertical rod anti-catching member 5 during the vibration reduction process of the device, the calculation of the preset compression amount of the vibration reduction spring 2-4 takes into account the double amplification factors of dynamics and elastic redundancy. This means that during and after the concrete pouring, the actual compression amount of the vibration reduction spring 2-4 is less than the pre-compression amount, that is, the inner step of the threaded sleeve 2-1 is always higher than the top of the vertical rod anti-catching member 5, the formwork elevation is always greater than the design elevation, and the U-shaped support 1 does not fully return to its position after the concrete pouring. The temporary hoop 3 provided in this device can achieve elevation return. The specific principle is as follows: In the temporary hoop 3, a pull wire switch 3-1 is used to control the opening of the anti-catching fastener 3-3. When a pulling force is applied to the pull rope, the cantilever bending spring column 3-1-3-1 abuts against the tooth part on the convex platform 3-1-4-2 of the anti-rotation gear, thereby driving the nut bushing 3-1-4 to rotate in the same direction, realizing the rotation of the nut 3-3-5; when the pulling force is removed, due to the action of the spring, the pull wire bushing 3-1-3 rotates reversely. At this time, since the check pin 3-1-5 abuts against the nut bushing 3-1-4, the nut bushing 3-1-4 and the nut 3-3-5 will not be driven to rotate in the same direction; when the pull rope is pulled again, the nut 3-3-5 continues to rotate with it, and when the pull rope is relaxed, the nut 3-3-5 does not rotate with it. Repeating this process achieves the effect of loosening the nut 3-3-5 by pulling the wire.

[0048] ​Since the pull wire switch 3-1 is fixed, the hexagonal long nut part 3-3-5 only rotates in place. The hexagonal hole of the bearing connecting plate 3-2-3 ensures that the long screw 3-3-4 cannot rotate with it. Instead, the long screw 3-3-4 moves axially. The bearing connecting plate 3-2-3 enables the long screw 3-3-4 to move axially without friction, and the pre-tension of the booster spring part makes it even more labor-saving for the long screw 3-3-4 to move axially. During installation, the spring part is in a pre-compressed state. When the long screw 3-3-4 moves axially, due to the spring pre-tightening force, the sliding connecting plate 3-2-2 is still in place and the fastening clip 3-2 has not been opened. As the pull wire switch 3-1 is continuously pulled, the long screw 3-3-4 continues to move backward, the spring resumes more and more, and the spring effect becomes smaller and smaller until the arc surface of the arc-shaped baffle of the long screw 3-3-4 contacts the sliding connecting plate 3-2-2. At this time, the fastening clip 3-2 is opened. The horizontal elliptical hole provided on the sliding connecting plate 3-2-2 of the fastening clip 3-2 provides space for the horizontal displacement of the long screw 3-3-4. At this time, the spring support adjusting pipe 2-5 and its upper part as a whole drop, causing the inner step of the threaded sleeve 2-1 to contact the top of the vertical rod anti-catching part 5, realizing the reset of the design elevation of the top support plate of the U-shaped support 1. This design uses the spring to delay the release time of the fastening clip 3-2, avoiding the situation where the spring support adjusting pipe 2-5 and its upper part as a whole drop instantly when the pull wire switch 3-1 is opened, and preventing the long section of the spring support adjusting pipe 2-5 from getting stuck when dropping in the fastening clip 3-2 due to the incomplete opening of the fastening clip 3-2, realizing that the fastening clip 3-2 provides enough dropping space for the spring support pipe, so as to fully restore the original elevation.

[0049] In a tall formwork support vertical vibration reduction device of the present invention, the vibration reduction spring 2-4 reduces the vertical kinetic energy transmitted during concrete pouring, achieving a vibration reduction effect, reducing the potential safety hazards caused by the direct impact of vertical dynamic loads on the formwork support, and improving the safety and reliability of concrete construction of the tall formwork support. At the same time, when multiple vertical vibration reduction devices are used, the single-point large impact load within the range of using this device is borne by multiple vertical vibration reduction devices within this range, avoiding the risk of local instability and overall collapse caused by excessive local impact pressure on a single vertical rod at the corresponding position of the formwork support due to local impact loads during concrete pouring. The adjustment of the preset compression amount enables this device to provide a relatively accurate spring vibration reduction effect under different slab thickness loads, enhancing the applicability of this device. By using the pull wire switch 3-1, the operator does not need to climb the support frame multiple times, but only needs to pull the pull rope at the bottom of the frame to open the temporary hoop 3, thus realizing the elevation return of the U-shaped support plate. After the temporary hoop 3 is opened, it still remains on the circular platform 1 of the bottom transition force transmission part and will not fall, providing safety protection. The design of the delay switch of the temporary hoop 3 prevents the spring support adjusting pipe 2-5 from getting stuck when dropping in the fastening clip 3-2.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
