Description

Technical Field

[0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a vertical vibration reduction device for a tall formwork frame. Background Art

[0002] The prior art, such as CN217353424U, discloses a construction engineering scaffold, which includes a vertical pole, a horizontal pole and a diagonal brace. The vertical pole is provided with a connecting plate, and the connecting ends of the horizontal pole and the diagonal brace are provided with buckle joints, which are fixed to the connecting plate by a latch, and the bottom of the latch is provided with an anti-slip structure, which includes a limit rotating plate, and the top surface of the limit rotating plate is provided with a through axial hole, and a rotating shaft is provided in the axial hole, and the upper end of the rotating shaft is connected to the bottom of the latch, and the lower end of the rotating shaft is provided with an anti-slip cap, and the anti-slip cap is larger than the aperture of the axial hole. It is a common formwork frame form of a disc buckle top support structure in the existing formwork system, but the formwork frame structure does not consider the vibration resistance of the entire formwork frame system, so that the entire structural system cannot meet the safety and stability requirements of the construction. As the main temporary facility in building construction, the high support frame plays a vital role in the safety of the entire construction process. In the prior art, insufficient consideration has been given to vibration reduction measures for high-support formwork, resulting in frequent collapse accidents of high-support formwork in recent years. The collapse of high-support formwork is mainly concentrated in the concrete pouring stage. The main reason is that the frame bears the effect of dynamic loads generated by concrete pouring. The dynamic loads greatly weaken the safety and reliability of the formwork. The dynamic loads come from pouring concrete, vibrating concrete, placing large fabrics, and the reciprocating motion of the concrete pump pipe when pumping concrete.

[0003] CN102031868A discloses a formwork frame for building construction, comprising a vertical pole, a horizontal pole, a top support, and a connecting buckle, wherein the horizontal pole is connected with the vertical pole by the connecting buckle to form the whole formwork frame, the formwork frame is provided with an adjustable top support at the top of the vertical pole, the adjustable top support is fixed on the vertical pole by a limit ring and becomes a part of the vertical pole, the horizontal pole is divided into two parts, a fixed-length horizontal pole and an adjustable horizontal pole, the adjustable horizontal pole is connected with the vertical pole and the fixed-length horizontal pole on the side of the formwork frame by the connecting buckle, and forms the whole structure of the formwork frame for building construction. When the above formwork frame system is adopted, especially when the concrete pump pipe is conveying concrete, a horizontal step load is generated and transmitted to the frame body through the friction force between the components, and at the same time, as the concrete is poured, the mass of the top of the frame body gradually increases, and it is in the form of an eccentric load, and the natural frequency of the frame body changes, and when the frequency of the external excitation load is close to the natural frequency of the frame body, a resonance effect is generated, and at this time the amplitude of the frame body increases significantly, and the frame body is very easy to be damaged and collapsed.

[0004] In summary, in order to address the potential safety hazard of system collapse caused by insufficient consideration of vibration reduction of the formwork frame system in the prior art, it is proposed to add special vibration reduction devices to the commonly used adjustable top supports and vertical poles to achieve vibration reduction and energy dissipation of horizontal dynamic loads transmitted from the upper part, reduce the dynamic response of tall formwork frames under horizontal dynamic loads during concrete pouring, and improve the safety of the frame.

Tighten the tightening bolt 2-5-1-4 in the screw hole of the threaded tube 2-5-1 on the spring support adjustment tube 2-5, so that the upper threaded tube 2-5-1 and the threaded sleeve 2-1 are fixed to the vertical pole; 6. Insert the damping spring 2-4 into the outer sleeve of the threaded sleeve 2-1, and use the screws 2-4-5 to connect the lower connecting ring 2-4-3 of the spring with the upper connecting pipe 2 (2-5-1-1) of the upper threaded pipe 2-5-1; 7.

Weld the vertical extension sleeve 2-2-2 and the annular wing plate 2-2-3 at the bottom of the lever nut 2-2-1 to form a whole, screw the multifunctional lever nut 2-2 onto the threaded sleeve 2-1, so that the ball 2-3-3 of the bidirectional thrust ball bearing 2-3 is in the annular track on the lower surface of the lever nut 2-2-1, align the annular track and the ball 2-3-3 on the upper surface of the sealing bottom plate 2-2-4, install the sealing bottom plate 2-2-4, and screw the tightening screw 2-2-7 into the screw hole on the side of the lever nut 2-2-1; 10. Screw the U-shaped support 1 into the threaded sleeve 2-1, remove the tightening bolt 2-5-1-4 in the screw hole of the threaded tube 2-5-1 on the spring support adjustment tube 2-5, and turn the multifunctional hand nut 2-2 to adjust the overhanging section length of the U-shaped support 1 to the designed elevation. This is state 1; 11. Remove the tightening screw 2-2-7 on the side of the lever nut 2-2-1, tighten the tightening bolt 2-5-1-4 in the screw hole of the threaded tube 2-5-1 on the spring support adjustment tube 2-5, so that the upper threaded tube 2-5-1 and the threaded sleeve 2-1 are fixed to the vertical pole. Referring to the scale (2-1-3) on the side of the threaded sleeve 2-1, turn the multifunctional lever 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 screw hole of the threaded tube 2-5-1 on the spring support adjustment tube 2-5. At this time, the multifunctional hand 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 support plate of the U-shaped support 1 exceeds the preset compression amount of the design elevation; 13. Remove the tightening bolt 3-2-9 from the screw hole 2-5-2-1 of the threaded tube 2-5-2 under the spring support adjusting tube 2-5, and start pouring the floor concrete. This is state two.

[0035] 2. After concrete pouring Since the preset compression amount of the vibration-damping spring 2-4 is calculated with the amplification factor taken into account, after the concrete pouring is completed, the actual compression amount of the vibration-damping spring 2-4 is less than the preset compression amount. At this time, the template elevation is greater than the design elevation, the inner step of the threaded sleeve 2-1 has not yet contacted the upright anti-stuck part 5 at the top of the upright, and the U-shaped support 1 has not fully returned to its position. This is state three.

[0036] The operator hooks the pull-wire switch 3-1 with a hook at the bottom of the frame and pulls the pull-wire switch 3-1, so that the temporary hoop 3 opens and does not fall off, and the spring support adjustment tube 2-5 automatically falls due to gravity, so that all parts above the transition force transmission member 4 fall down, so that the step formed by the large and small hole sections of the threaded sleeve 2-1 contacts the pole anti-stuck member 5 at the top of the pole, and the shock-absorbing spring 2-4 returns to the relaxed state to achieve the elevation return. This is state four.

[0037] When the device is installed, after the step inside the threaded sleeve 2-1 contacts the anti-stuck part 5 of the vertical pole, the exposed length of the screw rod is adjusted by the multifunctional hand nut 2-2, so that the top of the U-shaped support plate reaches the designed elevation; then the side tightening screw of the hand nut 2-2-1 is removed, the connection between the hand nut 2-2-1 and the threaded sleeve 2-1 is disconnected, and the multifunctional hand nut 2-2 is rotated to compress the spring, so that the preset compression amount of the vibration-damping spring 2-4 can be adjusted. The preset compression amount can be calculated according to different plate thicknesses and the amplification factor is considered. The accurate positioning of the pre-stressing position is achieved through the scale (2-1-3) groove on the side wall of the threaded sleeve 2-1. At this time, the top support plate of the U-shaped support 1 is higher than the designed elevation, and the protruding part is the preset compression amount of the vibration-damping spring 2-4. At this time, the pouring of concrete can achieve the reduction of vertical kinetic energy through the elastic action of the spring.

[0038] The process of presetting the compression amount of the spring of the present invention is as follows: The load g1 acting on a single vertical pole of the support frame includes the self-weight of the formwork, small ribs and other components; the load g2 acting on a single vertical pole of the support frame includes the self-weight of steel bars and concrete, as well as the self-weight of steel components and straight concrete components; the variable load q1 on a single vertical pole of the support frame includes the load of construction workers, construction equipment, and concrete material stacking that exceeds the thickness of the cast components 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 by a single vertical pole is:

[0039] According to the spring elastic coefficient k, considering the spring elastic redundancy magnification coefficient 1.2, the spring preset compression L can be obtained as:

[0040] In order to ensure that the inner step of the threaded sleeve 2-1 does not collide with the anti-stuck part 5 of the vertical pole during the vibration reduction process, the preset compression amount of the vibration reduction spring 2-4 is calculated taking into account the dual amplification coefficients of power and elastic redundancy, which means that during and after the concrete pouring, the actual compression amount of the vibration reduction spring 2-4 is less than the preload, that is, the inner step of the threaded sleeve 2-1 is always higher than the top of the anti-stuck part 5 of the vertical pole, the template elevation is always greater than the design elevation, and the U-shaped support 1 is not fully returned after the concrete pouring is completed. The temporary hoop 3 provided in the device can realize the elevation return. The specific principle is: the pull-wire switch 3-1 is used in the temporary hoop 3 to control the opening and closing of the anti-stuck fastener 3-3. When tension is applied to the pull rope, the cantilever bent spring column 3-1-3-1 abuts against the teeth on the anti-rotation gear boss 3-1-4-2, thereby driving the nut sleeve 3-1-4 to rotate in the same direction, thereby realizing the rotation of the nut 3-3-5; when the tension is removed, the pull rope sleeve 3-1-3 rotates in the opposite direction due to the action of the spring. At this time, since the check pin 3-1-5 abuts against the nut sleeve 3-1-4, it will not drive the nut sleeve 3-1-4 and the nut 3-3-5 to rotate in the same direction; when the pull rope is pulled again, the nut 3-3-5 continues to rotate, and the nut 3-3-5 does not rotate when the pull rope is loosened, and this reciprocating process is achieved to achieve the effect of pulling the wire and loosening the nut 3-3-5.

[0041] Because the pull-wire switch 3-1 is fixed, the hexagonal long nut 3-3-5 only rotates in place, and the hexagonal hole of the bearing connecting plate 3-2-3 ensures that the long screw 3-3-4 cannot rotate, while the long screw 3-3-4 moves axially. The bearing connecting plate 3-2-3 makes the axial movement of the long screw 3-3-4 frictionless, and the pre-tensioning force of the assisting spring component makes the axial movement of the long screw 3-3-4 more labor-saving. During installation, the spring component is in a pre-stressed state. When the long screw 3-3-4 moves axially, the sliding connecting plate 3-2-2 is acted on by the spring pre-tightening force, and the tight fastener 3-2 is not opened yet. As the pull continues The pull-wire switch 3-1 is moved, and the long screw 3-3-4 continues to move backward. The degree of spring recovery becomes larger and larger, and the spring effect becomes smaller and smaller, until the arc surface of the arc baffle of the long screw 3-3-4 contacts the sliding connecting plate 3-2-2. At this time, the clamping fastener 3-2 is opened, and the horizontal elliptical hole set on the sliding connecting plate 3-2-2 of the clamping fastener 3-2 provides space for the horizontal displacement of the long screw 3-3-4. At this time, the spring support adjusting tube 2-5 and its upper part fall as a whole, so that the inner step of the threaded sleeve 2-1 contacts the top of the vertical pole anti-stuck component 5, realizing the reset of the design elevation of the top support plate of the U-shaped support 1. This design uses a spring to delay the release time of the tightening fastener 3-2, preventing the spring-supported adjusting tube 2-5 and its upper portion from falling off as a whole when the pull-wire switch 3-1 is turned on. Since the tightening fastener 3-2 is not fully opened, the long section of the spring-supported adjusting tube 2-5 may get stuck when falling in the tightening fastener 3-2. The tightening fastener 3-2 provides enough space for the spring-supported tube to fall, thereby completely restoring the original elevation.

[0042] The vertical vibration reduction device of a tall formwork frame of the present invention reduces the vertical kinetic energy transmitted by concrete pouring through vibration reduction springs 2-4, thereby achieving a vibration reduction effect, reducing the potential safety hazards caused by the direct impact of vertical dynamic loads on the formwork frame, and improving the safety and reliability of concrete construction of tall formwork frames; at the same time, when multiple vertical vibration reduction devices are used, the single-point large impact load within the range of the device is borne by multiple vertical vibration reduction devices within the range, avoiding the risk of local impact pressure on a single vertical pole at a corresponding position of the formwork frame due to the local impact load during concrete pouring, resulting in local instability and overall collapse. The adjustment of the preset compression amount enables the device to provide a relatively accurate spring vibration reduction effect under different plate thickness loads, thereby enhancing the applicability of the device. The use of the pull-wire switch 3-1 eliminates the need for operators to climb the support frame multiple times. The temporary hoop 3 can be opened by pulling the pull rope at the bottom of the frame, thereby returning the elevation of the U-shaped support plate. After the temporary hoop 3 is opened, it remains on the circular platform 1 (4-1) of the bottom transition force transmission member and will not fall, thus ensuring safety. The design of the delayed switch of the temporary hoop 3 prevents the spring support adjustment tube 2-5 from getting stuck when it falls in the clamp fastener 3-2.
