Description

Technical Field

[0001] This utility model relates to the field of lifting climbing formwork technology, specifically to a lifting climbing formwork device to prevent concrete leakage. Background Technology

[0002] Climbing formwork, short for climbing frame, consists of three parts: climbing formwork, climbing frame, and climbing equipment. It has self-climbing capabilities and is an effective tool in the construction of tall structures such as shear wall systems, cylindrical systems, and bridge piers of large bridges. It also reduces the number of lifting machines and speeds up construction, resulting in good economic benefits. In use, the formwork and steel structure cage need to be coordinated to create a space for pouring concrete. After pouring concrete in this space, it is allowed to set. However, because the formwork partially contacts the already formed concrete wall at the bottom, excessive pressure cannot be applied to the overall formwork layer. This results in a gap between the formwork and the already formed concrete wall at the bottom, which can easily cause concrete to leak out during pouring, affecting the overall appearance quality.

[0003] Currently, the utility model patent with announcement number CN217205309U discloses a guide rail type climbing rod lifting climbing formwork system. This patent has a clamping mechanism at the lower end of the formwork, which can fit more tightly with the previously poured concrete wall to prevent grout leakage. This makes it less likely for the poured concrete to leak out and flow into the already formed concrete wall at the bottom, solving the problem of concrete easily leaking from the bottom of the formwork in the prior art, and enabling the overall system to maintain good aesthetics.

[0004] However, the above technical solution still has some shortcomings in actual use. Although the above technical solution can abut the joint of the concrete wall pouring through the cooperation between the spring and the elastic sealing strip, the concrete still needs to be vibrated after the concrete is poured. Using the spring abutment method, resonance may easily occur during the vibration process, causing the elastic sealing strip to shift from its original position. This can lead to concrete flowing out from the bottom, and its practicality has room for improvement. Based on this, this application provides a lifting climbing formwork device to prevent concrete leakage and solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a lifting climbing formwork device to prevent concrete leakage, thereby solving the problem in the prior art where the concrete poured at the top easily flows onto the already formed concrete wall panel at the bottom, affecting the overall aesthetics.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a lifting climbing formwork device to prevent concrete leakage, including a hydraulic climbing module, a main support, a hydraulic propulsion module and a template, wherein the hydraulic climbing module is disposed between the main support and the concrete wall, the hydraulic propulsion module is disposed on the main support and the output end is fixed to the template; The bottom of the template near the concrete wall has an installation groove, and a sealing mechanism is provided in the installation groove. The sealing mechanism includes a bonding film and an inflatable component that are detachably connected to the mounting groove. The contact surface between the bonding film and the concrete wall is smooth, and the outer side of the inflatable component abuts against the bonding film. The outer side of the inflatable component is abutted by an energy-absorbing component that absorbs vibration energy, and the main support is provided with an air supply component for inflating the inflatable component.

[0007] The above technical solution can be used to supply air to the inflation component, which will then expand and compress the bonding membrane, thereby sealing the connection between the concrete wall and the top pouring space through the bonding membrane.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the mounting groove has openings on both the front and back sides, and the bonding film includes a smooth film and two rough films connected to the smooth film. The width of the smooth film is equal to the width of the mounting groove, and the opposite sides of the two rough films abut against the inner wall of the mounting groove.

[0010] The above technical solution allows for easy separation of the smooth film after the concrete has solidified, while the rough film facilitates installation with positioning limitations.

[0011] Furthermore, the smooth film is a high-density polyethylene or polyester film, and the rough film is a flexible film with a rough surface.

[0012] The above technical solution has high tensile strength and wear resistance, and can be adhered to concrete through its smooth surface, while reducing adhesion.

[0013] Furthermore, the inflatable component includes an airbag filled in the mounting groove. The airbag is rectangular and has several partition pieces fixed inside. The separator divides the airbag into multiple inflatable spaces, and the outer side of the airbag abuts against the light-colored membrane.

[0014] By dividing the structure into multiple inflatable spaces, the rigidity after inflation can be improved, and the extrusion force can be applied to the light-emitting film relatively evenly within the rectangular shape constraint.

[0015] Furthermore, the air delivery component includes several air tubes disposed on the airbag, the air tubes being connected to the inside of the airbag and corresponding one-to-one with the inflation space; The air pipe is also equipped with a pressure gauge, and the main support is equipped with an air pump, the output end of which is connected to the air pipe.

[0016] The above technical solution enables the air pump to inflate the inflation space through the air pipe, and the inflation pressure can be easily monitored using a pressure gauge.

[0017] Furthermore, two mounting plates are connected by bolts in the mounting groove, and several through holes are provided on the roughened film for the bolts to pass through. The two mounting plates are symmetrically distributed vertically. The left side of the mounting plate and the left side of the mounting groove are located in the same vertical plane and abut against the glossy film. Two strip-shaped extrusion protrusions are fixed on the opposite side of the two mounting plates.

[0018] The above technical solution allows the mounting plate to be detachably connected to the mounting groove, and the action of the left side of the mounting plate can restrict the light film to the left side of the mounting groove, so that it can be properly adhered to the concrete wall.

[0019] Furthermore, the template has four limiting grooves on its front side, which are respectively used for the insertion of four extrusion protrusions and for the placement of corresponding rough films. The extrusion protrusion abuts against the corresponding rough film surface.

[0020] The above technical solution, through the combination of limiting groove and extrusion protrusion, can extrude and limit the rough film.

[0021] Furthermore, the energy-absorbing component includes a plurality of vibration-damping pads respectively bonded to opposite sides of the two mounting plates, and the vibration-damping pads are staggered with the bolts set on the mounting plates; The vibration isolation pad abuts against the outside of the airbag.

[0022] The above technical solution can separate the airbag and the template by using vibration isolation pads, thereby reducing the impact of vibration on the airbag.

[0023] Furthermore, the template has an installation hole on the side away from the concrete wall, which is connected to the inside of the installation groove, and the width of the installation hole is smaller than the width of the installation groove. A connecting plate is bolted to the outside of the template. The connecting plate is located outside the mounting hole. Several connecting rods are fixed to the side of the connecting plate near the airbag. A compression plate is fixed between the ends of the connecting rods near the airbag.

[0024] The above technical solution enables the compression plate to compress and limit the airbag.

[0025] Furthermore, both the extrusion plate and the connecting plate are provided with several through holes through which the air supply pipe passes; The extrusion plate abuts against the outside of the airbag, and the extrusion plate is movably connected to the inside of the mounting hole.

[0026] The above technical solution enables the trachea to extend normally and the extrusion plate to be removed from the mounting hole.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. It can effectively seal the connection between the space where concrete is poured and the bottom concrete wall, and prevent the sealing structure from resonating due to vibration; thus, it can also ensure effective sealing performance when the concrete is vibrated after pouring, preventing concrete from flowing out from the bottom of the formwork and affecting the overall aesthetics. 2. It also allows the bonding membrane located at the connection point to move relatively easily with the formwork and detach from the formed concrete wall, facilitating the normal progress of the climbing formwork construction process; at the same time, it can also replace the bonding membrane when the surface smoothness is affected, and it can be restricted by the limiting structure, so that while satisfying the bonding and sealing function, it will not have too much displacement, thereby ensuring the effectiveness of bonding and sealing.

[0030] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0032] Example: Reference Figure 1 and Figure 2 A lifting and climbing formwork device to prevent concrete leakage includes a hydraulic climbing module 1, a main support 2, a hydraulic propulsion module 3, and a template 4. The hydraulic climbing module 1 is located between the main support 2 and the concrete wall, and the hydraulic propulsion module 3 is located on the main support 2 with its output end fixed to the template 4. The bottom of the template 4 near the concrete wall has an installation groove 5, and a sealing mechanism 6 is provided in the installation groove 5. The sealing mechanism 6 includes a bonding film 61 detachably connected to the installation groove 5 and an inflatable component. The contact surface between the bonding film 61 and the concrete wall is smooth, and the outer side of the inflatable component abuts against the bonding film 61. An energy-absorbing component that absorbs vibration energy abuts against the outer side of the inflatable component. An air supply component for inflating the inflatable component is provided on the main support 2.

[0033] It should be noted that the hydraulic climbing module 1 is used to move the main support 2 on the formed concrete wall, so that the main support 2 can climb; the hydraulic propulsion module 3 can move the template 4 close to the steel frame to be poured, so that the template 4 and the corresponding steel frame are combined to form a space for pouring concrete; the main components of the hydraulic climbing module 1, the main support 2 and the hydraulic propulsion module 3, as well as the transmission and working methods, are all existing publicly available technologies, so they will not be described in detail.

[0034] refer to Figure 2 and Figure 4The mounting groove 5 has openings on both the front and back sides. The bonding film 61 includes a smooth film 611 and two rough films 612 connected to the smooth film 611. The width of the smooth film 611 is equal to the width of the mounting groove 5. The opposite sides of the two rough films 612 abut against the inner wall of the mounting groove 5. The smooth film 611 facilitates separation after the concrete has solidified, and the rough films 612 facilitate positioning during installation.

[0035] refer to Figure 4 and Figure 7 The smooth film 611 is a high-density polyethylene or polyester film with high tensile strength and wear resistance. It can be adhered to concrete through its smooth surface and can reduce adhesion. The rough film 612 is a flexible film with a rough surface. Specifically, it can be a thin rubber sheet with a large coefficient of friction, which facilitates positioning by abutting.

[0036] refer to Figure 4 and Figure 5 The inflatable component includes an airbag 62 filled in the mounting groove 5. The airbag 62 is rectangular, and several partitions 63 are fixed inside the airbag 62. The partitions 63 divide the airbag 62 into multiple inflatable spaces. The outer side of the airbag 62 abuts against the glossy film 611. By dividing it into multiple inflatable spaces, the rigidity after inflation can be improved, and under the constraint of the rectangular shape, the glossy film 611 can be subjected to relatively uniform compressive force.

[0037] When in use, the air chamber inside the airbag 62 is inflated, causing the airbag 62 to expand and press against the light film 611, thus allowing the light film 611 to adhere to the concrete wall.

[0038] refer to Figure 1 and Figure 3 The air delivery component includes several air tubes 64 disposed on the airbag 62. The air tubes 64 are connected to the inside of the airbag 62 and correspond one-to-one with the inflation space. The air tubes 64 are also equipped with pressure gauges 65. The main support 2 is equipped with an air pump 8. The output end of the air pump 8 is connected to the air tubes 64, so that the air pump 8 can inflate the inflation space through the air tubes 64. The pressure gauges 65 can be used to easily monitor the inflation pressure.

[0039] It should be noted that the vibration frequency during concrete vibration is generally 50-150Hz, and the preset monitoring pressure of pressure gauge 65 is 0.03MPa-0.1MPa. This can be adjusted according to actual needs to meet the stable contact requirements under different vibration frequencies.

[0040] Specifically, when it is necessary to obtain the actual required air pressure value, the airbag 62 is inflated to the preset pressure, and then the formwork 4 is directly vibrated by the vibrating equipment to determine the displacement of the airbag 62. If the displacement is within an acceptable range under this method, then in actual use, the vibration transmitted through the concrete will not have too much impact on the airbag 62, so that the stability of the sealing can be guaranteed.

[0041] refer to Figure 4 and Figure 6 Two mounting plates 71 are connected by bolts in the mounting groove 5. The rough film 612 has several through holes for the bolts to pass through, allowing the mounting plates 71 to be detachably connected to the mounting groove 5. The two mounting plates 71 are symmetrically distributed vertically. The left side of the mounting plate 71 is located in the same vertical plane as the left side of the mounting groove 5 and abuts against the smooth film 611. Two strip-shaped extrusion protrusions 72 are fixed on the opposite side of the two mounting plates 71. Under the action of the left side of the mounting plate 71, the smooth film 611 can be restricted to the left side of the mounting groove 5, so that it can be properly attached to the concrete wall.

[0042] In use, first place the smooth film 611 at the left opening of the mounting groove 5, then use the mounting plate 71 to press and position one of the rough films 612. After tensioning the smooth film 611, position the other rough film 612 to complete the positioning of the smooth film 611.

[0043] refer to Figure 4 and Figure 6 The template 4 has four limiting grooves 77 on its front side. The four limiting grooves 77 are respectively for the insertion of four extrusion protrusions 72. The limiting grooves 77 are for the placement of the corresponding rough film 612. The extrusion protrusions 72 abut against the surface of the corresponding rough film 612. Through the cooperation of the limiting grooves 77 and the extrusion protrusions 72, the rough film 612 can be extruded and limited.

[0044] refer to Figure 4 and Figure 8 The energy-absorbing component includes several vibration-damping pads 73 respectively bonded to opposite sides of two mounting plates 71. The vibration-damping pads 73 are staggered with the bolts set on the mounting plates 71. The vibration-damping pads 73 abut against the outside of the airbag 62. The vibration-damping pads 73 can be rubber vibration-damping pads 73 or silicone vibration-damping pads 73. The vibration-damping pads 73 can separate the airbag 62 and the template 4, thereby reducing the impact of vibration on the airbag 62.

[0045] refer to Figure 3 and Figure 4The template 4 has an installation hole on the side away from the concrete wall, which is connected to the inside of the installation groove 5. The width of the installation hole is smaller than the width of the installation groove 5. A connecting plate 74 is bolted to the outside of the template 4. The connecting plate 74 is located outside the installation hole. Several connecting rods 75 are fixed to the side of the connecting plate 74 near the airbag 62. A compression plate 76 is fixed between the ends of the connecting rods 75 near the airbag 62, which can compress and limit the airbag 62, thereby keeping the airbag 62 in the installation groove 5 for operation.

[0046] refer to Figure 3 and Figure 4 Both the extrusion plate 76 and the connecting plate 74 have several through holes through which the air supply pipe 64 passes, allowing the air pipe 64 to extend normally and perform the function of inflation or deflation through the air pipe 64; the extrusion plate 76 abuts against the outside of the airbag 62 and is movably connected to the inside of the mounting hole; the extrusion plate 76 can be removed from the mounting hole and can be disassembled.
