Description

Technical Field

[0001] The present invention relates to the technical field of concrete formwork, in particular to a self-compacting concrete formwork. Background Art

[0002] To meet the growing trend of larger, more complex, and higher-rise construction projects, the reinforcement in reinforced concrete structures is becoming increasingly complex, leading to increased construction difficulty. Conventional concrete construction requires vibrating the concrete, but the quality of the vibration significantly impacts the quality of the construction and can also cause noise and other issues. Self-compacting concrete eliminates the need for vibration and instead relies on its inherent properties to achieve a self-compacting shape, effectively resolving these issues.

[0003] Although self-compacting concrete can achieve the effect of self-compacting molding by relying on its own performance, the surrounding filling layer still needs to be sealed, and the air in the concrete needs to be removed. Relying solely on its own performance cannot achieve the effect of filling and exhausting air, which in turn affects the quality of the project. In the open self-compacting concrete formwork device of patent CN209836692U, a self-compacting concrete pouring cavity is formed by each formwork, and a clamping component is set to compact the concrete. At the same time, a slurry receiving port, a slurry discharge hole, etc. are set for the discharge of air. However, the position of the transverse pressure rod is fixed, resulting in poor exhaust effect. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a self-compacting concrete formwork to solve the above problems.

[0005] Based on the above-mentioned purpose, the present invention provides a self-compacting concrete formwork, including: a formwork frame, a track plate, a cross bar and a pressure mechanism; a slurry discharge port is provided on the side wall of the formwork frame, a track plate is provided above the formwork frame, a slurry inlet is provided on the track plate, a cross bar is provided above the track plate, and both ends of the cross bar are respectively connected to the pressure mechanism, and the pressure mechanism includes a fixing part, a motor, a cam, a connecting rod, a spring and a bracket, the fixing part is provided on the outside of the formwork frame, the fixing part is connected to the motor, the output end of the motor is connected to the cam, the cam is located on the cross bar, a connecting rod is installed on the cross bar, the upper and lower parts of the connecting rod are respectively provided with springs, one end of the connecting rod is connected to the fixing part, the other end of the connecting rod is connected to the bracket, and the bracket is connected to the fixing part.

[0006] Compared with the existing technology, the beneficial effect of the present invention is that the formwork frame and the track plate enclose a casting cavity, and by providing a slurry discharge port, the air is discharged from the cavity as the concrete is filled. A crossbar is provided above the track plate. After filling is completed, the motor is turned on, and the cam, motor, connecting rod and spring cooperate with each other to drive the crossbar to move up and down, thereby continuously pressurizing the filled self-compacting concrete on the track plate, expelling the remaining air, and sealing the surrounding filling layer. This template improves the concrete filling efficiency, allowing the concrete to completely fill the template and ensure the discharge of internal air, effectively improving the quality of concrete molding.

[0007] Furthermore, the pressurizing mechanism also includes a screw and a compression nut. One end of the screw is connected to the fixing member, and the other end of the screw passes through the crossbar and is threadedly connected to the compression nut. The screw and compression nut define the position of the track plate. By adjusting the compression nut, the crossbar moves downward, thereby pressing the track plate onto the template frame, covering the template frame.

[0008] Furthermore, the formwork frame includes a transverse formwork, a longitudinal formwork, a connecting plate, and a reinforcing plate. The transverse and longitudinal forms are connected end to end perpendicular to each other. The top surfaces of the transverse and longitudinal forms are each provided with a connecting groove, into which the connecting plate is clamped. The reinforcing plate is an L-shaped structure, with its ends connected to the side walls of the transverse and longitudinal forms, respectively. The transverse formwork, longitudinal formwork, and connecting plate enclose a space for pouring concrete, and the reinforcement plate is provided to strengthen the connection between the longitudinal and transverse forms, preventing the connection from being unable to withstand pressure when pouring concrete later.

[0009] Furthermore, the formwork includes a sealing cover, a sealing plate, and a clamping block. The sealing cover is connected to the slurry inlet, and a sealing plate is disposed above the sealing cover. One end of the sealing plate is rotatably connected to the track plate, and the other end of the sealing plate is slidably connected to the clamping block, which is connected to the track plate. After the concrete is poured, the sealing cover is closed and then compressed with the sealing plate and clamping block to prevent the sealing cover from being pushed open during the solidification process of the internal concrete, thereby affecting the quality of the formed concrete.

[0010] Furthermore, the template further comprises a slide rail and a cover plate, wherein the slide rails are respectively connected to both sides of the slurry discharge port, and the cover plate is slidably connected to the slide rails. The slurry discharge port is opened and closed by sliding the cover plate.

[0011] Furthermore, the template also includes a pressure plate, the side walls of which are connected to the side walls of the crossbar. The pressure plate increases the contact area between the crossbar and the track plate, thereby better pressurizing the track plate and improving the quality of concrete pouring.

[0012] Furthermore, the fixing member includes a fixing platform and a motor seat. A fixing hole is opened at the bottom of the fixing platform, and the motor seat is connected to the top of the fixing platform; the motor seat is used to fix the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0019] like Figure 1 As shown in FIG, the self-compacting concrete formwork proposed by the present invention is composed of a formwork frame, a track plate 3, a crossbar 9 and a pressure mechanism. The formwork frame is composed of a transverse formwork 2, a longitudinal formwork 1, a connecting plate 25 and a reinforcing plate 27. The transverse formwork 2 and the longitudinal formwork 1 are arranged perpendicular to each other and are connected end to end to form a rectangular frame. Figure 2 As shown, the upper surfaces of the transverse form 2 and the longitudinal form 1 are respectively provided with connecting grooves 26, and connecting plates 25 are clamped in the connecting grooves 26. The transverse form 2 and the longitudinal form 1 are connected together through the connecting plates 25 to enclose the space for pouring concrete. A reinforcing plate 27 is provided at the connection between the transverse form 2 and the longitudinal form 1. The reinforcing plate 27 is an L-shaped structure. A connecting nut 28 is used to connect one end of the reinforcing plate 27 to the transverse form 2, and the other end of the reinforcing plate 27 is connected to the longitudinal form 1. In this embodiment, the longitudinal form 1 includes two, and the ends at which the two longitudinal forms 1 are connected are respectively fixedly connected to a fixing block 23. The fixing block 23 is provided with a mounting hole. Bolts are passed through the two mounting holes and tightened with nuts 24 to connect the two longitudinal forms 1 together. As shown Figure 3As shown, a slurry discharge port 20 is provided on the longitudinal mold 1 for exhausting air during concrete pouring. Slide rails 21 are fixedly connected to the longitudinal mold 1 on both sides of the slurry discharge port 20, and a cover plate 22 is slidably connected to the slide rail 21 to close the slurry discharge port 20.

[0020] The template frame is connected to a track plate 3, which is provided with a slurry inlet 16. A sealing cover 17 covers the slurry inlet 16, and a sealing plate 18 is provided above the sealing cover 17. A mounting block is fixedly connected to the track plate 3 on one side of the sealing cover 17. A rotating shaft is connected to the mounting block. The end of the rotating shaft is mounted on one end of the sealing plate 18 and is rotatably connected to the sealing plate 18. A clamping block 19 is fixedly connected to the track plate 3 on the other side of the sealing cover 17. The clamping block 19 has a slot, which allows the clamping block 19 to be open on one side of the sealing cover 17 and on the left or right side adjacent to the side. By rotating the sealing plate 18, the other end of the sealing plate 18 can slide into the slot.

[0021] A cross bar 9 is provided on the track plate 3. The cross bar 9 is parallel to the cross mold 2. Pressure plates 13 are connected to both sides of the cross bar 9 respectively. The pressure plates 13 are parallel to the cross bar 9. The side walls of the pressure plates 13 are fixedly connected to the side walls of the cross bar 9. Pressure mechanisms are connected to both ends of the cross bar 9. The pressure mechanism is composed of a fixing part, a motor 7, a cam 29, a connecting rod 12, a spring 10, a bracket, a screw 14 and a clamping nut 15. The fixing part is composed of a fixing platform 4 and a motor seat 6. The fixing platform 4 is an I-shaped structure. The end of the fixing platform 4 is connected to the outer wall of the longitudinal mold 1. The bottom surface of the fixing platform 4 is provided with a fixing hole 5 for connecting to the ground. A motor seat 6 is fixedly connected to the upper end of the fixing platform 4 away from the side mold. The motor seat 6 is connected to the motor 7, such as Figure 4 As shown, the output end of the motor 7 is connected to the cam 29, and the cam 29 is arranged on the cross bar 9. A connecting rod 12 is installed on the cross bar 9, and the upper and lower parts of the connecting rod 12 are both covered with springs 10. One end of the connecting rod 12 is fixedly connected to the upper surface of the fixed platform 4. The bracket is composed of two support columns 8 and an anti-slip block 11. The two support columns 8 are respectively fixedly connected to the upper surface of the fixed platform 4 on both sides of the connecting rod 12. The two ends of the anti-slip block 11 are respectively fixedly connected to the top of the two support columns 8, and the other end of the connecting rod 12 is fixedly connected to the anti-slip block 11. The screw 14 is located between the track plate 3 and the connecting rod 12. The screw 14 is installed in the cross bar 9. One end of the screw 14 is fixedly connected to the fixed platform 4, and the other end of the screw 14 is threadedly connected to the clamping nut 15. The clamping nut 15 is located on the cross bar 9.

[0022] During use, first place the longitudinal form 1 and transverse form 2 where construction is required. Insert the connecting plate 25 into the connecting groove 26 at the top of the longitudinal form 1 and transverse form 2, thereby enclosing the space for pouring concrete. Bolts are then used to securely connect the reinforcing plate 27 to the joint between the longitudinal form 1 and transverse form 2, making the connection between the two forms more secure and preventing the joint from being unable to withstand pressure when pouring concrete. Bolts are then inserted into the fixing holes 5 and tightened, securing the fixing platform 4 to the ground. The fixing platforms 4 on both sides are tightly against the longitudinal form 1, supporting the longitudinal form 1 and increasing its bearing capacity. Remove the sealing plate 18 from the slot in the block 19, remove the sealing cover 17, and fill the interior with self-compacting concrete through the slurry inlet 16. At this point, adjust the compression nut 15 to move the crossbar 9 downward, so that the track plate 3 covers the casting cavity formed by the longitudinal form 1 and transverse form 2. Slide the cover plate 22 upward to open the slurry outlet 20, and air will be discharged from the cavity as the concrete is filled. When filling is complete, the motor 7 is turned on, and the cam 29 on the output shaft of the motor 7 is used to squeeze the crossbar 9. At the same time, the crossbar 9 drives the pressure plate 13 to move together, squeezing the track plate 3. Under the coordinated action of the cam 29 and the spring 10 on the connecting rod 12, the crossbar 9 reciprocates up and down, continuously squeezing the track plate 3, thereby pressurizing the filled self-compacting concrete, promoting the discharge of residual air, and ensuring that the concrete fills the entire formwork frame, thereby improving the efficiency of concrete filling and the quality of concrete forming.
