Description

Technical Field

[0001] The invention relates to the technical field of civil engineering and construction, and in particular to a template vibration reduction structure for strengthening the stability of a foundation and a construction method thereof. Background Art

[0002] In the field of foundation construction of building projects, the foundation is a key part connecting the pile foundation and the superstructure, and its construction quality is of vital importance. Traditional foundation construction mostly uses ordinary wooden formwork, and the formwork needs to be removed after pouring concrete. This process not only consumes manpower, material resources and time, but also easily causes damage to the concrete around the foundation, affecting the integrity of the structure. With the acceleration of the process of building industrialization, the technology of non-removal formwork has emerged, aiming to simplify the construction process and improve construction efficiency. Especially in foundation construction, if the wooden formwork can be removed, it will greatly optimize the construction process. Wooden formwork has always occupied a certain share in the construction formwork market due to its convenient material acquisition, relatively low cost and flexible processing. Its transformation and application in the non-removal system has a good economic and practical basis.

[0003] The existing non-removable wooden formwork on the market is usually improved on the basis of ordinary wooden formwork. On the one hand, starting from the design of the formwork structure, the connection between the various parts of the wooden formwork is strengthened, and the overall stability of the formwork is enhanced by splicing and self-tapping screw reinforcement. On the other hand, the surface of the wooden formwork is treated and coated with waterproof and anti-corrosion coatings to prevent groundwater erosion and concrete alkaline corrosion, extend the service life of the wooden formwork, and allow it to be retained in the foundation structure for a long time as a part of the load-bearing.

[0004] However, during the construction of the foundation, various vibration sources are inevitable, such as vibration from concrete vibrators, operation of machinery and equipment on the construction site, and movement of transport vehicles. Due to the material characteristics of the wooden formwork itself, its rigidity is relatively low, and vibration waves propagate inside the wooden formwork, which can easily loosen the wooden formwork connectors and affect the overall stability of the wooden formwork. Summary of the invention

[0005] The purpose of the present invention is to provide a formwork vibration reduction structure and a construction method thereof that do not require dismantling and are used to enhance the stability of the foundation, so as to improve the problem of various vibration sources during the foundation construction process, such as vibration of concrete vibrators, operation of mechanical equipment on the construction site, and the movement of transport vehicles, which affect the overall stability of the formwork.

[0006] The present invention adopts the following technical solution:

The wooden formwork vibration damping structure includes a plurality of formworks, a longitudinal fastening assembly, and a lateral support assembly. The ends of the plurality of formworks are spliced together to enclose a base space for pouring. A plurality of the formworks on each side of the base space are stacked and adhered, and are fastened and connected in the vertical direction by the longitudinal fastening assembly to form a formwork side wall. The lateral support assembly is installed between the formwork side wall and the side wall of the foundation pit to provide lateral support for the formwork side wall.

[0008] The lateral support assembly includes a support plate, a counter plate, and a first vibration damping support unit and a second vibration damping support unit installed between the support plate and the counter plate. The support plate is erected and abuts against the formwork side wall. The counter plate is arranged opposite to the support plate and abuts against the side wall of the foundation pit. The first vibration damping support unit includes a first slider and a first vibration damping rod group. The first slider is slidably installed on the counter plate. One end of the first vibration damping rod group is hinged to the support plate, and the other end is connected to the first slider. The second vibration damping support unit includes a second slider, a second vibration damping rod group, and a plurality of fasteners. The second slider is slidably installed on the counter plate and can press against the first slider to slide. The first end of the second vibration damping rod group is fixedly connected to the second slider, and the second end is slidably installed on the support plate to drive the second vibration damping rod group to lift between the support plate and the counter plate under the sliding of the second slider. The fasteners are used to fasten the second slider to the counter plate after the second slider slides in place, and to fasten the second end of the second vibration damping rod group to the support plate.

[0009] Further, a reinforcing rib is arranged horizontally on the outer side wall surface of the formwork, and a card slot is formed longitudinally on the reinforcing rib. The support plate includes a vertical plate portion and a horizontal plate portion vertically formed at the bottom end of the vertical plate portion and extending towards the side wall of the foundation pit. The horizontal plate portion extends to abut against the side wall of the foundation pit. The vertical plate portion is clamped in the card slot, and a gusset plate is connected between the vertical plate portion and the horizontal plate portion to form a triangular structure.

[0010] Further, the first vibration damping rod group includes a cylinder plate one, a plate member one, and an elastic member one. The cylinder plate one is hinged to the support plate. The plate member one is slidably inserted into the cylinder plate one. One end of the plate member one is connected to the first slider.

A clamping plate for clamping and holding the support plate is arranged at one end of the second vibration damping rod group. The fasteners further include a plurality of fixing bolts two for locking the clamping plate to the support plate.

[0012] By adopting the above technical solution, the first fixing bolt can fix the second slider in the chute of the abutment plate, preventing it from sliding during vibration.

The limiting rod is fixedly connected to the second slider and abuts against the adjusting plate.

[0014] Further, a flat groove is formed in the cylinder plate two, penetrating through both sides of the cylinder plate two relatively. The adjusting plate is slidably installed in the flat groove, and the adjusting plate has adjusting outer plates extending out of both sides of the flat groove. Both ends of the elastic member two are compressively connected to the adjusting plate and the cylinder plate two. The limiting rod is arranged parallel to the outside of the cylinder plate two to limit and hold the sliding of the adjusting outer plate.

[0015] Further, the lateral support assembly further includes a downward sliding decompression structure. The downward sliding decompression structure includes a fixed pulley and a pulling rope. The fixed pulley is installed on the top of the supporting plate. One end of the pulling rope is connected to the adjusting outer plate. The pulling rope changes the force application direction through the fixed pulley so as to pull the adjusting plate from outside the foundation pit to compress the elastic member two, for facilitating the downward pressing of the second slider to slide.

[0016] Further, a clamping plate is provided at one end of the plate member two. The clamping plate is slidably clamped on the supporting plate. A baffle is arranged inside the clamping plate.

[0020] The object of the present invention is to provide a vibration damping structure for a non-removable cap wood formwork and its construction method, adopting the following technical solution:

[0021] A construction method of a template vibration damping structure for strengthening the stability of a bearing platform without demolition, comprising:

[0022] S100: Excavate a foundation pit at a predetermined position and lay a cushion layer in the foundation pit;

[0023] S200: Enclose the pouring area of the foundation platform in the foundation pit through a template. Correspondingly, form template side walls on each side of the foundation platform space. Install columns by fitting them to the template at both ends of the template. Install a number of fixing clips in sequence along the length direction of the columns; Open holes between the reinforcing ribs of adjacent templates and install fastening rods through them. Tighten the fastening nuts threadedly connected to both ends of the fastening rods to tighten adjacent templates;

[0024] S300: Install a support plate on the template side wall. The support plate has a vertical plate portion and a horizontal plate portion. The horizontal plate portion abuts against the cushion layer, and the abutting plate abuts against the side wall of the foundation pit. Open a chute on the plate surface of the abutting plate facing the support plate. Place a first slider in the chute. One end of the first vibration damping rod group is hinged to the support plate. Swing the first vibration damping rod group, and the other end of the first vibration damping rod group abuts against the bottom surface of the first slider; Then place a second slider in the chute of the abutting plate so that the second slider abuts against the first slider. Press down the second slider to slide down, so that the pressed first slider slides, thereby driving the other end of the first vibration damping rod group abutting against the first slider to slide down, driving the first vibration damping rod group to compress. After the second slider slides down a certain length, correspondingly, the second vibration damping rod group drops to the corresponding position between the support plate and the abutting plate, and then lock the two ends of the second vibration damping rod group to the corresponding support plate or abutting plate respectively through fasteners.

[0025] By adopting the above technical solutions, a number of templates are spliced and surrounded to form a pouring space for the foundation platform. By stacking and fitting one side of the foundation platform, it can better adapt to the shape and size requirements of the foundation platform and ensure the accuracy of pouring; The reinforcing ribs on the outer side wall of the template enhance the overall rigidity of the template and reduce the deformation caused by vibration; The card slots on the reinforcing ribs cooperate with the support plate. The support plate forms a stable triangular support structure with the side wall of the foundation pit through the horizontal plate portion and the corner plate, effectively transferring the lateral force received by the template to the side wall of the foundation pit, further improving the stability of the template; The second vibration damping rod group compresses the first vibration damping rod group, and stores the compression stress of the first vibration damping rod group by fixing the second vibration damping rod group, which helps the first vibration damping rod group to resist vibration. When the vibration is transmitted to the first slider, the first elastic member is compressed, which can absorb part of the vibration energy and play a buffering role, reducing the influence of vibration on the template connecting parts.

[0026] In summary, the beneficial technical effects of the present invention include at least one of the following template vibration damping structures for strengthening the stability of the bearing platform without demolition and its construction method as follows:

[0027] 1. A number of templates are spliced and surrounded to form a pouring space for the foundation platform. By stacking and fitting on one side of the foundation platform, it can better adapt to the shape and size requirements of the foundation platform, ensuring the accuracy of pouring. The reinforcing ribs on the outer side wall of the template enhance the overall rigidity of the template, reducing deformation caused by vibration. The clamping grooves on the reinforcing ribs cooperate with the support plates, and the support plates form a stable triangular support structure with the side wall of the foundation pit through the transverse plate part and the corner plates, effectively transferring the lateral force received by the template to the side wall of the foundation pit, further improving the stability of the template. By compressing the first shock-absorbing rod group with the second shock-absorbing rod group and storing the compressive stress of the first shock-absorbing rod group by fixing the second shock-absorbing rod group, it helps the first shock-absorbing rod group to resist vibration. When the vibration is transmitted to the first slider, the first elastic member is compressed, which can absorb part of the vibration energy, playing a buffering role and reducing the impact of vibration on the template connecting parts.

[0028] 2. The clamping plate can slide along the length direction of the second plate member, facilitating the adjustment of the length of the second shock-absorbing rod group according to the actual situation, such as the distance between the foundation platform and the inner wall of the foundation pit, to achieve the support and shock-absorbing effect. The setting of the baffle and the elastic pad not only helps to prevent the clamping plate from sliding excessively but also plays a buffering role during vibration, protecting the support plate and the second shock-absorbing rod group from damage.

[0029] 3. Through the design of the pull rope, fixed pulley and adjusting plate, construction workers can conveniently pull the adjusting plate outside the foundation pit to compress the second elastic member, which enables the stiffness of the shock-absorbing structure to be flexibly adjusted according to different vibration conditions, improving the shock-absorbing effect. The setting of the limiting rod can maintain the compressed state of the second elastic member, ensuring the continuous and stable operation of the shock-absorbing structure.

Detailed implementation mode

[0036] The following is combined with the attached Figure 1 - attached Figure 5 , and the present invention will be further described in detail.

[0037] Embodiment 1:

[0038] Please refer to Figure 1 , a formwork damping structure for strengthening the stability of the bearing platform, which is installed in the foundation pit 1 on the ground and is used to enclose a pedestal space 12 for pouring. Preferably, a cushion layer 11 is provided on the bottom surface of the foundation pit 1 for installing the formwork damping structure to improve the stability of the formwork damping structure. In this embodiment, the foundation pit 1 presents a regular rectangular pit-shaped structure, and correspondingly, the pedestal space 12 is also designed as a rectangle.

[0039] Please further refer to Figure 2 , the formwork damping structure includes a plurality of formworks 2, a longitudinal fastening component, and a lateral support component. The longitudinal fastening component is used to fasten and connect the formworks in the up and down directions, and the formworks 2 on the same side of the pedestal space 12 form a formwork side wall. The lateral support component is installed between the formwork side wall and the side wall of the foundation pit 1 to provide lateral support (i.e., horizontal support) for the formwork side wall.

[0040] A number of formworks 2 are installed in the foundation pit 1. The formworks 2 are made of wood. The formworks 2 can be fixed by leveling with cement slurry. The two ends of the formworks 2 are spliced and surrounded by each other to form the pouring contour of the foundation platform space 12. A number of formworks 2 on each side of the foundation platform space 12 are closely arranged by means of stacking and fitting, and are tightly connected in the vertical direction by longitudinal fastening components, so as to control the height of the poured foundation platform space 12. Further, at both ends of the formworks 2, columns 9 are installed in close contact with the formworks 2. A close-fitting connection method is adopted between the columns 9 and the formworks 2 to ensure the structural integrity. And, along the length direction of the columns 9, a number of fixing clips 91 are arranged at equal intervals. In this embodiment, it is preferably two. The two ends of the fixing clips 91 are respectively fixed to the formworks 2 on both sides of the columns 9 by high-strength bolts (not shown in the figure). In this embodiment, it is preferably twelve formworks 2 that participate in the surrounding, and three formworks 2 are attached to one side of the foundation platform space 12.

[0041] On the outer surface of the formwork 2, reinforcing ribs 21 are integrally formed along the transverse direction (i.e., its length direction) or fixed by screws (not shown in the figure). Through holes are opened between adjacent reinforcing ribs 21 in the vertical direction and fastening rods 8 are inserted. The fastening rods 8 are in clearance fit with the through holes on the reinforcing ribs 21 to ensure smooth installation. Threaded fastening nuts 81 are connected to both ends of the fastening rods 8. By rotating the fastening nuts 81, they are tightly abutted against the reinforcing ribs 21, so as to tighten the adjacent formworks 2.

[0042] Refer to Figure 1 、 Figure 2 , the construction process is further elaborated. In the foundation pit 1, first, according to the design requirements, the area of the foundation platform space 12 is enclosed by using the formworks 2, and the height of the foundation platform space 12 is controlled by the overlapping operation between the formworks 2. Subsequently, columns 9 are installed in close contact with the formworks 2 at both ends of the formworks 2, and a number of fixing clips 91 are installed in sequence along the length direction of the columns 9 to ensure the stable connection of each component. Immediately afterwards, through holes are opened between adjacent reinforcing ribs 21 and fastening rods 8 are installed through them. The construction personnel use professional tools to tighten the fastening nuts 81 threadedly connected to both ends of the fastening rods 8 to tighten the adjacent formworks 2 with a strong pre-tightening force.

[0043] Please refer to Figure 1 - Figure 3, the lateral support assembly includes a support plate 3, a resisting plate 4, and a first vibration damping support unit and a second vibration damping support unit installed between the support plate 3 and the resisting plate 4. The support plate 3 is erected and abuts against the side wall of the wooden formwork. The resisting plate 4 abuts against the side wall of the foundation pit 1 relative to the support plate 3. The first vibration damping support unit includes a first slider 411 and a first vibration damping rod group 5. The first slider 411 is slidably installed on the resisting plate 4. One end of the first vibration damping rod group 5 is hinged to the support plate 3, and the other end is connected to the first slider 411. The second vibration damping support unit includes a second slider 412, a second vibration damping rod group 6, and a plurality of fasteners 7. The second slider 412 is slidably installed on the resisting plate 4 and can press against the first slider 411 to slide. One end of the second vibration damping rod group 6 is fixedly connected to the second slider 412, and the other end is slidably installed on the support plate 3 to drive the second vibration damping rod group 6 to lift between the support plate 3 and the resisting plate 4 under the sliding of the second slider 412. The fasteners are used to fasten the second slider 412 to the resisting plate 4 and fasten one end of the second vibration damping rod group 6 located on the support plate 3 to the support plate 3 after the second slider 412 slides in place.

[0044] A card slot 211 is formed in the longitudinal direction (i.e., the up and down direction) on the reinforcing rib 21. The upper and lower card slots 211 of adjacent reinforcing ribs 21 correspond to each other. In this embodiment, preferably, the two card slots 211 of adjacent two reinforcing ribs 21. The support plate 3 is snap-fitted and installed in the card slot 211 along the up and down direction. The support plate 3 includes a vertical plate portion and a horizontal plate portion 31 vertically formed at the bottom end of the vertical plate portion and extending towards the side wall of the foundation pit 1. The vertical plate portion is snap-fitted in the card slot 211, and the horizontal plate portion 3 extends to closely abut against the side wall of the foundation pit 1. To further strengthen the structural stability, a gusset plate 32 is connected between the vertical plate portion and the horizontal plate portion 31. The gusset plate 32 is fixedly arranged by screws and is connected to the vertical plate portion and the horizontal plate portion 31 to form a stable triangle, improving the ability of the lateral support assembly to resist lateral forces.

[0045] Refer to Figure 1 , Figure 3 , the resisting plate 4 abuts against the side wall of the foundation pit 1 and is arranged opposite to the vertical plate portion of the support plate 3. It can be understood that the resisting plate 4 can be fixedly arranged at the end of the horizontal plate portion 31 by bolts. Clamping grooves 42 are arranged on both sides of the resisting plate 4 along the up and down direction. Thus, a mud guard 421 is installed between adjacent resisting plates 4 by using the clamping grooves 42, which can block the soil falling from the side wall of the foundation pit 1. The mud guard 421 can be made of wood.

[0046] Refer to Figure 3 , Figure 4 , Figure 5 , a sliding groove 41 is formed on the surface of the resisting plate 4 facing the vertical plate portion along the up and down direction. A first slider 411 is slidably arranged in the sliding groove 41. One end of the first vibration damping rod group 5 abuts against the first slider 411, and the other end is preferably on the vertical plate portion of the support plate 3 through a pin shaft.

[0047] The first shock-absorbing rod group 5 includes a first cylinder plate 51 hinged to the support plate 3, a first plate member 52 slidably inserted into the first cylinder plate 51, and a first elastic member 53 installed in the first cylinder plate 51 to elastically connect the first cylinder plate 51 and the first plate member 52. The first cylinder plate 51 can be made of metal material. A clearance fit is adopted between the first plate member 52 and the first cylinder plate 51 to ensure smooth sliding. One end of the first plate member 52 is in close contact with the first slider 411. In this embodiment, the first elastic member 53 is a high-strength spring, and one end thereof is fixedly welded to one end of the first plate member 52 in the first cylinder plate 51.

[0048] Refer to Figure 3 、 Figure 4 、 Figure 5 As shown in FIGS.

[0049] Refer to Figure 3 、 Figure 4 、 Figure 5 The second slider 412 is arranged in the chute 41, above the first slider 411, and can slide downward to abut against the top surface of the first slider 411. One end of the second shock-absorbing rod group 6 is connected to the second slider 412, and the other end of the second shock-absorbing rod group 6 abuts against the vertical plate portion of the support plate 3. Further, a lower pressing plate 10 is slidably arranged in the chute 41 and above the second slider 412. The staff presses the lower pressing plate 10 to move through a tool, so that the second slider 412 slides downward, and then abuts against the first slider 411 to slide, thereby compressing the first shock-absorbing rod group 5.

[0050] The second shock-absorbing rod group 6 includes a second cylinder plate 61, a second plate member 62, an adjusting plate 612, a second elastic member 63 and a limiting rod 72. One end of the second cylinder plate 61 is fixedly connected to the second slider 412, and the other end sleeves the second plate member 62. The adjusting plate 612 is slidably inserted into the second cylinder plate 61. The second elastic member 63 elastically presses between the adjusting plate 612 and the second cylinder plate 61. The limiting rod 72 is fixedly connected to the second slider 412 and abuts against the adjusting plate 612.

[0051] A clamping plate 621 is formed at one end of the second plate member 62 installed on the support plate 3. The clamping plate 621 can be slidably arranged along the length direction of the second plate member 62 for clamping and holding on the support plate 3. The clamping plate 621 is made of high-strength alloy steel material and has good clamping rigidity. The fastener further includes a plurality of second fixing bolts 6211 arranged on the clamping plate 621. The second fixing bolts 6211 are respectively fixed in close contact with the front and side surfaces of the vertical plate portion of the support plate 3, so as to stably install one end of the second shock-absorbing rod group 6 on the support plate 3 and cooperate to play the shock-absorbing effect.

[0052] The second plate 62 and the second cylinder plate 61 also adopt clearance fit to facilitate sliding adjustment. The clamping plate 621 can slide along the length direction of the second plate 62. Further, a baffle 622 is arranged inside the clamping plate 621. The baffle 622 is arranged on the side facing the support plate 3 with an elastic pad 6221 that abuts against the support plate 3. The elastic pad 6221 is made of rubber material, which can not only buffer the collision between the baffle 622 and the support plate 3, but also increase the sliding resistance of the clamping plate 621 along the length direction of the second plate 62, and fill the small gap to improve the vibration reduction effect.

[0053] The second cylinder plate 61 is provided with a flat groove 611, which penetrates the two sides of the second cylinder plate 61 relatively. The adjustment plate 612 is slidably installed in the flat groove 611, and one end of the adjustment plate 612 abuts or is connected to the second plate 62. The adjustment plate 612 has an adjustment outer plate 6121 extending on both sides of the flat groove 611, and the adjustment outer plate 6121 and the flat groove 611 maintain good sliding accuracy. The second elastic member 63 is installed in the second cylinder plate 61, and one end of the elastic member 63 is connected to the adjustment plate 612. In this embodiment, the second elastic member 63 also uses a high-strength spring, and the other end is welded and connected to the second cylinder plate 61. The second elastic member 63 is compressed on the adjustment plate 612 and the second cylinder plate 61. The limit rod 72 is arranged parallel to the outer side of the second cylinder plate 61 to block the sliding direction (i.e., the direction toward the abutment plate 4) of the adjustment outer plate 6121 under the elastic force of the second elastic member 63.

[0054] The lateral support assembly includes a downward decompression structure, which includes a fixed pulley 7 and a pull rope 71. The fixed pulley 7 is installed on the top of the support plate 3. Specifically, two fixed pulleys 7 are provided on the top of the support plate 3 corresponding to the adjustment outer plate 6121, and the fixed pulley 7 is fixedly connected to the support plate 3 by bolts. One end of the pull rope 71 is connected to the adjustment outer plate 6121, and the other end of the pull rope 71 is wound around the fixed pulley 7 to change the direction of force application so as to pull the adjustment plate 612 from outside the foundation pit 1 to move and compress the elastic member 2 63, thereby releasing the holding force of the elastic member 2 63 on the limit rod 72, so as to facilitate the downward pressing of the second slider 412. In this way, the compression state of the elastic body 63 is flexibly adjusted by the fixed pulley 7 and the pull rope 71 to adjust the stiffness of the vibration reduction structure and improve the vibration reduction effect. It can be understood that the length of the limit rod 72 is designed to match the compression state of the elastic member 2 63, so that the compression state of the elastic member 2 63 can be maintained.

[0055] Specifically, the adjusting outer plate 6121 is provided with a through hole, and a knot 711 is provided at one end of the pull rope 71. The pull rope 71 passes through the through hole and the knot 711 abuts against the end of the adjusting outer plate 6121 facing away from the support plate 3. With such a design, the construction workers pull the pull rope 71 outside the foundation pit 1 to easily pull the adjusting plate 612 to compress the elastic member 2 63.

[0056] One end of the limiting rod 72 is fixedly connected to the second slider 412, and the other end is used to abut against the adjusting outer plate 6121. Specifically, one end of the limiting rod 72 penetrates into the abutting plate 4 and is tightly inserted and fixed in the hole on the second slider 412. This hole is drilled through by a tool according to the fixed position after the second damping rod group 6 is fixed.
