Description

Technical Field

[0001] This utility model relates to the field of template fixing technology, specifically a secondary structure template fixing device. Background Technology

[0002] In secondary structure construction, the quality of formwork fixing for structural columns, ring beams, lintels, and other components directly affects the concrete forming effect. Traditional formwork fixing often uses steel wire wrapping and binding. Although this fixing method can achieve the fixing effect, it is complicated to operate, prone to loosening, has low safety, and poor stability. Existing formwork fixing often adopts the step-by-step tightening method. Step-by-step tightening has a very high application rate in this field. However, existing step-by-step tightening requires hammering to create a tension effect, and the hammering position is required. If the hammering position is deviated, the fixing will easily fail. Moreover, existing step-by-step tightening requires manual hammering, and the hammering angle and position are prone to deviation. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a secondary structure template fixing device to solve the problems mentioned in the background art, such as the tendency of traditional step-by-step manual tapping to deviate from the tapping position, the inability to ensure that the tapping is in the designated position every time, poor fixing stability, and high operation difficulty.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a secondary structure template fixing device, comprising a main rod, a first clamping part, and a second clamping part slidably disposed on the main rod. The main rod is slidably provided with a striking component. The second clamping part is disposed between the first clamping part and the striking component. The second clamping part has a clamping end for abutting against the template and a receiving wall for the striking component to strike it toward the template. The clamping end and the receiving wall are integrally formed. The striking component is capable of striking the receiving wall.

[0005] As a further improvement of this utility model, the striking component is provided with a positioning device at one end connected to the main rod for positioning the striking component after sliding on the main rod. The positioning device includes a pin. The main rod is provided with a plurality of through holes along its length for the pin to pass through for positioning. The striking component is provided with a punch corresponding to the position of the impacted wall. The punch can strike the second clamping part towards the template.

[0006] As a further improvement of this utility model, the striking component includes a long arm and a positioning shaft disposed on the long arm. The hammer is provided with an adjusting rod, which slides up and down along the length of the long arm. The positioning shaft is inserted and engaged with the adjusting rod and the long arm. The positioning shaft passes through the adjusting rod and connects to the long arm, thereby positioning the adjusting rod on the long arm.

[0007] As a further improvement of this utility model, the positioning shaft is a straight positioning shaft. After the positioning shaft passes through the punch and is connected to the long arm, it can limit the punch to swing circumferentially or slide up and down.

[0008] As a further improvement of this utility model, the punch has an impact end, the impact end is movably connected to the adjusting rod, a spring is provided between the impact end and the adjusting rod, one end of the spring abuts against the adjusting rod and the other end abuts against the impact end, and the punch has an operating rod for a person to pull the punch in the opposite direction of the template to squeeze the spring.

[0009] Compared with the prior art, this utility model provides a secondary structure template fixing device with the following advantages: the clamping end is integrally formed with the impact wall, avoiding the risk of loosening of the split structure, improving the structural stability and service life of the device, and ensuring direct and reliable transmission of clamping force; the striking component is slidably set on the main rod, which can accurately strike the impact wall, quickly push the second clamping part towards the template and cooperate with the first clamping part to clamp the template, which shortens the template positioning time and improves construction efficiency and striking accuracy compared with the traditional fixing method; the second clamping part slides to adapt to the main rod and forms an adjustable clamping distance with the first clamping part, which can adapt to secondary structure templates of different thicknesses and spacings, and has strong versatility; Attached Figure Description

[0012] As shown in the figure, the present invention provides a secondary structure template fixing device to achieve the above objectives. The device includes a main rod 1, a first clamping part 2, and a second clamping part 3 slidably disposed on the main rod 1. The main rod 1 is slidably provided with a striking component 4. The second clamping part 3 is disposed between the first clamping part 2 and the striking component 4. The second clamping part 3 has a clamping end 31 for abutting against the template and a receiving wall 32 for the striking component 4 to strike it toward the template. The clamping end 31 and the receiving wall 32 are integrally formed. The striking component 4 can strike the receiving wall 32.

[0013] In the implementation of this solution, the first clamping part 2 can be fixed to one end of the main rod 1 by welding or bolting, while the second clamping part 3 is sleeved on the main rod 1 and can slide freely along the length of the main rod 1 to adjust the distance between it and the first clamping part 2. The main rod 1 is also fitted with a striking component 4, which can also slide along the main rod 1. The clamping end 31 of the second clamping part 3 and the impact wall 32 are made by integral casting process, with no splicing gap between them. The clamping end 31 has an arc-shaped or flat structure to adapt to different template surfaces and is used to abut against the template side wall. In use, the first clamping part 2 is first placed against one side template or support structure, the second clamping part 3 is slid so that the clamping end 31 fits against the other side template, and then the striking component 4 is slid to the impact wall 32 so that it can strike the impact wall 32. After that, the connection position of the second clamping part 3 and the main rod 1 can be engaged with the main rod 1. The first clamping part 2 and the second clamping part 3 work together to clamp the template. This striking clamping method in this solution is the conventional striking clamping method of step-by-step tightening in the prior art.

[0014] As an improved specific embodiment, a positioner is provided at the end of the striking component 4 connected to the main rod 1 for positioning the striking component 4 after sliding on the main rod 1. The positioner includes a pin 41. The main rod 1 is provided with a plurality of through holes 42 along its length for the pin 41 to pass through for positioning. A punch 43 is provided on the striking component 4 corresponding to the position of the impact wall 32. The punch 43 can perform hammering on the second clamping part 3 towards the template.

[0015] In this scheme, a positioner is set at the connection end between the striking component 4 and the main rod 1. The main rod 1 has several through holes 42 along its length for the pins 41 to pass through. The striking component 4 is fitted with a hammer 43 at the corresponding impact wall 32. The impact end face of the hammer 43 is parallel and adapted to the impact wall 32. During implementation, the pins 41 are inserted through the holes of the striking component 4 into the through holes 42 of the main rod 1 to fix the striking component 4 and prevent it from slipping back. When adjustment is required, the pins 41 are pulled out to slide the striking component 4, which improves the reliability of the fixation. The operation is simple and the adjustment is convenient.

[0016] As an improved specific embodiment, the striking component 4 includes a long arm 44 and a positioning shaft 45 disposed on the long arm 44. The hammer 43 is provided with an adjusting rod 46, which slides up and down along the length of the long arm 44. The positioning shaft 45 is inserted and engaged with the adjusting rod 46 and the long arm 44. The positioning shaft 45 passes through the adjusting rod 46 and connects with the long arm 44, thereby positioning the adjusting rod 46 on the long arm 44.

[0017] In implementation, the striking component 4 includes a long arm 44 and a positioning shaft 45. One end of the long arm 44 is connected to the sliding sleeve of the main rod 1, and the other end extends vertically. The hammer 43 is connected to an adjusting rod 46, which slides up and down through the long arm 44. The long arm 44 has several positioning holes, and the adjusting rod 46 has corresponding through holes 42. First, the adjusting rod 46 is slid according to the height of the impact wall 32 so that the hammer 43 is aligned with the impact wall 32. The positioning shaft 45 is then inserted and fixed through the holes of the adjusting rod 46 and the long arm 44. Then, the striking component 4 is slid along the main rod 1 to strike the hammer 43 or the striking component 4 to apply force, adapting to impact walls 32 of different heights and improving the versatility of the lifting device.

[0018] As an improved specific implementation, the positioning shaft 45 is a straight positioning shaft 45. After the positioning shaft 45 passes through the punch 43 and is connected to the long arm 44, it can limit the punch 43 to swing circumferentially or slide up and down.

[0019] In this scheme, the positioning shaft 45 is in the shape of a straight line, the adjusting rod 46 has a straight through hole 42, and the long arm 44 has a corresponding straight positioning hole. The positioning shaft 45 is inserted through the two holes for a fit. The straight positioning shaft 45 not only restricts the adjusting rod 46 from sliding up and down along the long arm 44, but also prevents the hammer 43 from swinging around the adjusting rod 46, ensuring that the hammer 43 is always aligned with the wall 32 being hit. After the positioning shaft 45 is assembled, the hammer 43 moves along the main rod 1 closely following the striking part 4, and the hammering is without deviation, thus improving the stability of the fixation.

[0020] As an improved specific embodiment, the punch 43 has an impact end, which is movably connected to the adjusting rod 46. A spring 47 is provided between the impact end and the adjusting rod 46. One end of the spring 47 abuts against the adjusting rod 46, and the other end abuts against the impact end. The punch 43 has an operating rod 48 for a person to pull the punch 43 in the opposite direction to the template to squeeze the spring 47.

[0021] When implementing this solution, after adjusting and fixing the height of the impact hammer 43, the sliding striking component 4 brings the impact end close to the impact wall 32; the operating lever 48 is held to pull the impact end, compressing the spring 47 to store energy, and after releasing, the spring 47 pushes the impact end to hit the impact wall 32, realizing automatic hammering, reducing labor intensity and impact wear.

[0022] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
