Description

Technical Field

[0001] The invention belongs to the technical field of concrete pouring, in particular to an auxiliary supporting device used for steel formwork installation construction. Background Art

[0002] In the process of civil engineering construction, in order to improve the quality of concrete pouring, formwork is usually required for enclosure. There are generally two types of formwork materials. One is steel formwork, which has high strength and hardness and can withstand greater concrete side pressure and deadweight. The other is wooden formwork, which is lighter and easier to carry and install. During the formwork installation process, a special formwork support device is required. The formwork support device can be used in water conservancy, roads and bridges, construction, municipal engineering and other projects.

[0003] The existing auxiliary support device can only improve the stability of the steel formwork in the support of the steel formwork, but it is not convenient to help the steel formwork to be demolded. As the concrete hardens, the moisture in the concrete will form a water film on the surface of the steel formwork. The surface tension generated by this water film will cause adsorption between the concrete and the steel formwork, resulting in a firm connection between the steel formwork and the concrete, which is difficult to demold. When demolding, the steel formwork is generally detached by breaking or hammering. This demolding method is relatively violent, resulting in a large tearing force of the steel formwork on the concrete. After the steel formwork is detached, it is easy to tear off a part of the concrete, resulting in an uneven surface of the concrete after pouring.

[0004] To this end, the present invention provides an auxiliary support device for steel formwork installation construction. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art and solve the problem that the existing auxiliary supporting device can only improve the stability of the steel formwork in the support of the steel formwork, but is not convenient for helping the steel formwork to be demoulded, as the concrete hardens, the moisture in the concrete will form a water film on the surface of the steel formwork, and the surface tension generated by this water film will cause adsorption between the concrete and the steel formwork, resulting in a firm connection between the steel formwork and the concrete, which is difficult to demould, and the steel formwork is generally detached by breaking or hammering during demoulding. Such a demoulding method is relatively violent, resulting in a large tearing force of the steel formwork on the concrete, and a part of the concrete is easily torn off after the steel formwork is detached, resulting in the problem of uneven concrete surface after pouring.

[0024] Through the above technical solution, the base 1 is fixed next to the poured concrete through the anchor rod 57, the first hydraulic cylinder 6 is started, and the first support plate 7 is pushed to move so that the first support plate 7 fits the steel formwork, thereby providing auxiliary support to the steel formwork through the first support plate 7, thereby improving the stability of the steel formwork in supporting the concrete, and the demolding agent is loaded into the cavity 8 through the feed port 19, and the demolding agent is allowed to enter the injection head 31 along the first pipe 9, the second pipe 10, and the hose 24 through the feeding assembly, and the demolding agent is injected into the fitting place between the steel formwork and the concrete through the injection head 31, so as to help the steel formwork to be smoothly demolded from the concrete.

[0025] Specifically, the top of the injection head 31 is fixedly connected to the first sliding shaft 28, the outer wall of the first sliding shaft 28 is slidably connected to the connecting plate 25, the top of the first sliding shaft 28 is fixedly connected to the first limit block 29, the outer wall of the first sliding shaft 28 is sleeved with a third spring 30, the bottom of the third spring 30 is fixedly connected to the injection head 31, the top of the third spring 30 is fixedly connected to the connecting plate 25, one side of the connecting plate 25 is fixedly connected to the mounting frame 26, the inner wall of the mounting frame 26 is fixedly connected to the magnet 27, and the interior of the connecting plate 25 is provided with a through hole for the hose 24 to pass through.

[0026] Through the above technical solution, after the first support plate 7 is erected, the magnet 27 is adsorbed on the steel formwork, and the injection head 31 is made to fit at the angle between the steel formwork and the concrete through the third spring 30, and the position of the injection head 31 is easily adjusted through the hose 24, so that the release agent can be injected into different positions where the steel formwork and the concrete fit.

[0027] Specifically, a liquid inlet cavity is provided inside the injection head 31, and a liquid outlet groove 32 is provided inside the injection head 31 and on one side close to the liquid inlet cavity. One end of the hose 24 extends to the inside of the liquid outlet groove 32, and a plurality of diverter plates 33 are fixedly connected to the inner wall of the liquid inlet cavity at equal intervals, and the inclination angles of the plurality of diverter plates 33 increase successively from the inside to the outside.

[0028] Through the above technical solution, the demolding agent enters the liquid outlet trough 32 along the hose 24, and enters the liquid inlet cavity along the liquid outlet trough 32. The demolding agent entering the liquid inlet cavity flows downward. Through the provision of a plurality of diverter plates 33, the demolding agent can increase the flow range, which is convenient for injection to different positions where the steel formwork and concrete are bonded.

[0029] Specifically, the feeding assembly includes a sleeve 11, which is fixedly installed at the bottom of the second pipe 10. The inner wall of the second pipe 10 is symmetrically provided with two one-way valves 12 with the sleeve 11 as the center. The two one-way valves 12 are both opened in the direction of the hose 24. The inner wall of the sleeve 11 is slidably connected with a piston plate 13, and the bottom of the piston plate 13 is fixedly connected with a piston rod 14. The bottom of the piston rod 14 passes through the sleeve 11 and is fixedly connected with a top plate 16. The outer wall of the piston rod 14 is sleeved with a second spring 15, and the top of the second spring 15 is fixedly connected to the sleeve 11. The second spring 15 is fixedly connected to the sleeve 11. 5 is fixedly connected to the top plate 16, the inner wall of the mounting plate 2 is rotatably connected with a first rotating shaft 17, one end of the first rotating shaft 17 passes through the mounting plate 2 and is fixedly connected with a first cam 18, the first cam 18 is located below the top plate 16, the outer wall of the mounting plate 2 is fixedly connected with a motor 20, the output end of the motor 20 extends to the inside of the mounting plate 2, the outer wall of the output end of the motor 20 is fixedly connected with a first pulley 21, the outer wall of the first rotating shaft 17 is fixedly connected with a second pulley 23, and the first pulley 21 and the second pulley 23 are connected through a transmission belt 22.

[0030] By means of the above technical solution, the motor 20 is started, the motor 20 drives the first pulley 21 to rotate, and the second pulley 23 is driven to rotate by the transmission belt 22, so that the first rotating shaft 17 rotates, and then the first cam 18 is driven to rotate. When the raised end of the first cam 18 rotates upward, the top plate 16 is pushed to move upward, and the piston rod 14 is driven upward, so that the piston plate 13 moves upward. While the top plate 16 moves upward, the second spring 15 is pressed. When the raised end of the first cam 18 rotates downward, the top plate 16 is pushed downward under the action of the second spring 15. The motor 20 moves, driving the piston plate 13 to move downward, thus reciprocating. After the motor 20 is started, it can drive the piston plate 13 to move up and down reciprocatingly. When the piston plate 13 moves downward, it cooperates with the two one-way valves 12 to allow the demolding agent in the cavity 8 to enter the sleeve 11 along the first pipe 9 and the second pipe 10. When the piston plate 13 moves upward, it cooperates with the two one-way valves 12 to allow the demolding agent in the sleeve 11 to enter the injection head 31 along the second pipe 10 and the hose 24. Thus reciprocating, after the motor 20 is started, the demolding agent can be continuously added to the injection head 31.

[0031] Specifically, the inner wall of the first support plate 7 is symmetrically slidably connected to two connecting frames 36, one end of the two connecting frames 36 is fixedly connected to the second support plate 37, the inner wall of the first support plate 7 is symmetrically slidably connected to two clamping blocks 38, one end of the two clamping blocks 38 is fixedly connected to the fourth spring 39, the two fourth springs 39 are fixedly connected to the first support plate 7, a plurality of clamping grooves 41 are equidistantly provided on the outer wall of the connecting frame 36, the clamping blocks 38 fit the inner walls of the clamping grooves 41, and an adjustment component is provided inside the first support plate 7.

[0032] Through the above technical solution, the fourth spring 39 is set to enable the block 38 to be inserted into the slot 41, and the position of the slot 41 can be fixed by the limit of the block 38, thereby fixing the position of the connecting frame 36 and the second support plate 37. When the height of the steel formwork is high, it is necessary to adjust the support area to improve the stability of the support. At this time, the block 38 is moved out of the slot 41 through the adjustment component. After the limit of the block 38 is lost, the connecting frame 36 can be slid in the first support plate 7, so that the two second support plates 37 are opened to each other, thereby increasing the support area for the steel formwork. After adjusting the position of the second support plate 37, the block 38 is inserted into the slot 41 again through the adjustment component in conjunction with the fourth spring 39 to fix the position of the second support plate 37.

[0033] Specifically, the adjustment component includes a second hydraulic cylinder 43, which is fixedly installed inside the first support plate 7. The output end of the second hydraulic cylinder 43 is fixedly connected to a fixed plate 44, which is slidably connected to the first support plate 7. The inner wall of the first support plate 7 is symmetrically slidably connected to two push rods 42. The outer wall of the block 38 is provided with an inclined groove 40 for cooperating with the push rod 42. The outer wall of the fixed plate 44 is symmetrically rotationally connected to two connecting shafts 45, and the two connecting shafts 45 are rotationally connected to the two push rods 42 respectively.

[0034] Through the above technical solution, when adjusting the position of the second support plate 37, the second hydraulic cylinder 43 is retracted to move the fixed plate 44, thereby driving the two connecting shafts 45 to rotate simultaneously, so that the two push rods 42 are opened to each other. The push rod 42 is pressed against the inclined groove 40 on the outer wall of the block 38 during the movement. As the push rod 42 moves, the block 38 is driven to move and the fourth spring 39 is pressed. When the push rod 42 moves to the root of the inclined groove 40, the block 38 is separated from the groove 41. When fixing the position of the second support plate 37, the second hydraulic cylinder 43 is used to push the fixed plate 44 to reset, so that the two push rods 42 are reset, and the fourth spring 39 is cooperated to reset the block 38 and insert it into the groove 41.

[0035] Specifically, the top of the slide plate 3 is fixedly connected with the first spring 4 , the top of the first spring 4 is fixedly connected with the mounting plate 2 , and the output end of the motor 20 is fixedly connected with the second cam 35 .

[0036] Through the above technical solution, the first hydraulic cylinder 6 controls the first support plate 7 and the second support plate 37 to press against the steel formwork, and the motor 20 starts and drives the second cam 35 to rotate. When the raised end of the second cam 35 rotates to the upper side, the slide plate 3 is pushed to move upward, so that the first support plate 7 and the second support plate 37 move upward. When the first support plate 7 and the second support plate 37 move upward, the friction between the steel formwork and the first support plate 7 and the second support plate 37 drives the steel formwork to move upward, and helps the steel formwork and the concrete to break away from the sticky state, thereby facilitating the subsequent demoulding of the steel formwork. When the steel formwork moves upward, it is in a fit state with the concrete surface, and the lateral tearing force on the concrete is small, which prevents the steel formwork from carrying part of the concrete during the movement, resulting in the loss of the concrete surface.

[0037] Specifically, the inner wall of the second support plate 37 is symmetrically rotatably connected to two second rotating shafts 46, the outer walls of the two second rotating shafts 46 are fixedly connected to pulleys 47, the outer walls of the pulleys 47 are equidistantly fixedly connected to a plurality of rubber pads 48, and the outer wall of the second support plate 37 is provided with a limiting component.

[0038] Through the above technical solution, by setting the limit assembly, the pulley 47 and the rubber pad 48 can only rotate counterclockwise, and cannot rotate clockwise. Therefore, when the first support plate 7 and the second support plate 37 move upward, the pulley 47 cannot rotate, so that the rubber pad 48 can be pressed against the surface of the steel formwork. As the first support plate 7 and the second support plate 37 move upward, the friction force of the rubber pad 48 can drive the steel formwork to move upward. When the steel formwork and the concrete are too firmly adhered, the static friction force between the rubber pad 48 and the steel formwork is less than the adsorption force between the steel formwork and the concrete. At this time, as the first support plate 7 and the second support plate 37 move upward, the pulley 47 and the rubber pad 48 are driven to move upward. After the first support plate 7 and the second support plate 37 move upward, the first elastic member 48 is pressed. Spring 4, when the raised end of the second cam 35 rotates to the bottom, the first support plate 7 and the second support plate 37 are driven to move downward under the action of the first spring 4, and at this time, the pulley 47 and the rubber pad 48 are rotated so that the rubber pad 48 does not rub against the steel formwork, so that the first support plate 7 and the second support plate 37 can slide downward smoothly after moving upward, and thus reciprocate. When the steel formwork and concrete are too firmly adhered, as the motor 20 is started, the rubber pad 48 can be driven to move upward continuously, and the adsorption force between the steel formwork and the concrete is continuously consumed by lifting the steel formwork upward multiple times, which is convenient for separating the steel formwork from the concrete, and thus the steel formwork is lifted upward multiple times, so that the demoulding of the steel formwork is gentle, avoiding damage to the concrete surface caused by violent hammering.

[0039] Specifically, the limit assembly includes a positioning plate 51, which is fixedly mounted on the outer wall of the second support plate 37, one end of the second rotating shaft 46 passes through the second supporting plate 37 and is fixedly connected to a rotating disk 49, and a plurality of latch teeth 50 are fixedly connected to the outer wall of the rotating disk 49 at equal intervals, one side of the latch teeth 50 is set as a straight surface, and the other side is set as an inclined surface, the inner wall of the positioning plate 51 is slidably connected to two second sliding shafts 52, one end of the two second sliding shafts 52 is fixedly connected to the limiting plate 54, the outer wall of the limiting plate 54 is symmetrically fixedly connected to two clip strips 55, the clip strips 55 fit the outer wall of the clip teeth 50, the other ends of the two second sliding shafts 52 are fixedly connected to the second limit block 53, the outer wall of the second sliding shaft 52 is sleeved with a fifth spring 56, one end of the fifth spring 56 is fixedly connected to the positioning plate 51, and the other end of the fifth spring 56 is fixedly connected to the limiting plate 54, and the elastic force of the first spring 4 is greater than the elastic force of the fifth spring 56.

[0040] Through the above technical solution, when the first support plate 7 and the second support plate 37 move upward, the friction between the rubber pad 48 and the steel template causes the pulley 47 to rotate clockwise, driving the second rotating shaft 46 to rotate clockwise, causing the turntable 49 and the latching tooth 50 to rotate clockwise. At this time, the straight surface of one side of the latching tooth 50 is pressed against the bottom of the clip strip 55. Under the limiting action of the clip strip 55, the latching tooth 50 cannot rotate, and then the pulley 47 and the rubber pad 48 cannot rotate. The first support plate 7 and the second support plate When the first support plate 7 and the second support plate 37 move downward, the friction between the rubber pad 48 and the steel template causes the pulley 47 to rotate counterclockwise, driving the second rotating shaft 46 to rotate counterclockwise, causing the turntable 49 and the latch tooth 50 to rotate counterclockwise. At this time, the inclined surface on the other side of the latch tooth 50 presses against the top of the latch strip 55. Under the pushing action of the inclined surface of the latch tooth 50, the latch strip 55 moves and compresses the fifth spring 56. As a result, when the first support plate 7 and the second support plate 37 move downward, the pulley 47 and the rubber pad 48 are driven to rotate counterclockwise.

[0041] Specifically, a sealing gasket 34 is fixedly connected to one side and the bottom of the injection head 31 , and the sealing gasket 34 is made of rubber material.

[0042] Through the above technical solution, the sealing gasket 34 is set to seal the joint between the injection head 31 and the steel formwork and the concrete, preventing the release agent from overflowing when injecting the release agent. The release agent continuously enters the injection head 31, and under the action of pressure, the release agent can easily penetrate into the joint between the steel formwork and the concrete.

[0043] When in use, the base 1 is fixed to the poured concrete by the anchor rod 57, and the first hydraulic cylinder 6 is started to push the first support plate 7 to move so that the first support plate 7 fits the steel formwork, thereby providing auxiliary support to the steel formwork through the first support plate 7, thereby improving the stability of the steel formwork supporting the concrete, and the fourth spring 39 is provided to insert the clamping block 38 into the clamping groove 41, and the position of the clamping groove 41 can be fixed by the limit of the clamping block 38, thereby fixing the position of the connecting frame 36 and the second support plate 37. When the height of the steel formwork is high, it is necessary to adjust the support area to improve the stability of the support, and the second hydraulic cylinder 43 is retracted to move the fixing plate 44 to drive the two connecting shafts 45 to rotate at the same time, so that the two push rods 42 are opened to each other, and the push rods 42 are moved during the movement. During the process, the inclined groove 40 of the outer wall of the card block 38 is pressed against. With the movement of the push rod 42, the card block 38 is driven to move and the fourth spring 39 is pressed. After the limit of the card block 38 is lost, the connecting frame 36 can be slid in the first support plate 7 to make the two second support plates 37 open to each other and increase the supporting area of ​​the steel formwork. After adjusting the position of the second support plate 37, the fixing plate 44 is pushed to reset by the second hydraulic cylinder 43 to reset the two push rods 42, and the fourth spring 39 is used to reset the card block 38 and insert it into the card slot 41. The demolding agent is loaded into the cavity 8 through the feed port 19. After the first support plate 7 is set up, the magnet 27 is adsorbed on the steel formwork, and the injection head 31 is fitted to the angle between the steel formwork and the concrete through the third spring 30, and the injection head 31 is pressed against the steel formwork and the concrete. The hose 24 is provided to facilitate adjusting the position of the injection head 31, so as to inject the demolding agent into different positions where the steel formwork and the concrete are bonded. The motor 20 is started to drive the second cam 35 to rotate. When the raised end of the second cam 35 rotates to the upper side, the slide plate 3 is pushed to move upward, so that the first support plate 7 and the second support plate 37 move upward. When the first support plate 7 and the second support plate 37 move upward, the pulley 47 rotates clockwise through the friction between the rubber pad 48 and the steel formwork, driving the second rotating shaft 46 to rotate clockwise, so that the turntable 49 and the latching tooth 50 rotate clockwise. At this time, the straight surface of one side of the latching tooth 50 is pressed against the bottom of the clamping strip 55. Under the limiting action of the clamping strip 55, the latching tooth 50 cannot rotate, and the pulley 47 and the rubber pad 48 cannot rotate. The friction force of the pad 48 can drive the steel formwork to move upward. While the steel formwork moves upward, it is in contact with the concrete surface, and the horizontal tearing force on the concrete is small, which prevents the steel formwork from carrying part of the concrete during the movement, resulting in the loss of the concrete surface. When the steel formwork and the concrete are too firmly adhered, the static friction force between the rubber pad 48 and the steel formwork is less than the adsorption force between the steel formwork and the concrete. At this time, as the first support plate 7 and the second support plate 37 move upward, the pulley 47 and the rubber pad 48 are driven to move upward. After the first support plate 7 and the second support plate 37 move upward, the first spring 4 is pressed. When the raised end of the second cam 35 rotates to the bottom, the first support plate 7 and the second support plate 37 are driven to move downward under the action of the first spring 4.When the first support plate 7 and the second support plate 37 move downward, the friction between the rubber pad 48 and the steel template causes the pulley 47 to rotate counterclockwise, driving the second rotating shaft 46 to rotate counterclockwise, causing the turntable 49 and the latch tooth 50 to rotate counterclockwise. At this time, the inclined surface on the other side of the latch tooth 50 presses against the top of the clamping strip 55. Under the pushing action of the inclined surface of the latch tooth 50, the clamping strip 55 moves and compresses the fifth spring 56. As a result, when the first support plate 7 and the second support plate 37 move downward, the pulley 47 and the rubber pad 48 are driven to rotate counterclockwise. The rotation of the set pulley 47 and the rubber pad 48 prevents the rubber pad 48 from rubbing against the steel template, so that the first support plate 7 and the second support plate 37 can slide downward smoothly after moving upward. This reciprocating motion, when the steel formwork and the concrete are too firmly adhered, as the motor 20 is started, it can drive the rubber pad 48 to move upward continuously. By lifting the steel formwork upward multiple times, the adsorption force between the steel formwork and the concrete is continuously consumed, which facilitates the separation of the steel formwork from the concrete. In addition, the steel formwork is lifted upward multiple times, making the demoulding of the steel formwork gentler, avoiding damage to the concrete surface caused by violent hammering. When the motor 20 is started, it drives the first pulley 21 to rotate, and through the set transmission belt 22, it drives the second pulley 23 to rotate, so that the first rotating shaft 17 rotates, driving the first cam 18 to rotate. When the raised end of the first cam 18 rotates to the upper side, it pushes the top plate 16 to move upward, driving the piston rod 14 moves upward, so that the piston plate 13 moves upward, and the top plate 16 moves upward while pressing the second spring 15. When the raised end of the first cam 18 rotates to the bottom, under the action of the second spring 15, the top plate 16 moves downward, driving the piston plate 13 to move downward, thereby reciprocating. After the motor 20 is started, it can drive the piston plate 13 to move up and down reciprocatingly. When the piston plate 13 moves downward, it cooperates with the two one-way valves 12 to allow the stripping agent in the cavity 8 to enter the sleeve 11 along the first pipe 9 and the second pipe 10. When the piston plate 13 moves upward, it cooperates with the two one-way valves 12 to allow the stripping agent in the sleeve 11 to enter the injection head 31 along the second pipe 10 and the hose 24, thereby reciprocating. After the motor 20 is started, the mold release agent can be continuously added to the injection head 31. The sealing pad 34 can be used to seal the joint between the injection head 31 and the concrete to prevent the mold release agent from overflowing when injecting the mold release agent. The mold release agent continuously enters the injection head 31. Under the action of pressure, the mold release agent can penetrate into the joint between the steel formwork and the concrete. The mold release agent enters the liquid outlet trough 32 along the hose 24 and enters the liquid inlet cavity along the liquid outlet trough 32. The mold release agent in the liquid inlet cavity flows downward. Through the plurality of diverter plates 33, the mold release agent can increase the circulation range, which is convenient for injection at different positions where the steel formwork and the concrete are joined, and helps the steel formwork to be smoothly demolded from the concrete.
