Description

Technical Field

[0001] The utility model relates to the technical field of casting clamps, in particular to a template casting clamp for civil engineering structures. Background Art

[0002] During the construction of cast-in-place concrete structure projects, it is necessary to use a formwork casting fixture for civil engineering structures to fix the formwork structure erected on site, and then pour concrete into the fixed formwork to form the required concrete structure.

[0003] According to the search, the Chinese patent website with announcement number CN217759968U discloses "a formwork casting fixture for civil engineering structures". By setting a clamping mechanism, two clamping plates are placed on both sides of the casting formwork, and then the knob is turned to drive the threaded rod to rotate, and then the two clamping plates are pushed to move to the middle to fix the casting formwork. While the clamping plates move to the middle, they move with the main rod to increase the stability of the clamping plates during movement, so that the casting formwork can be stably clamped. However, the adjustment of the clamping mechanism needs to be performed on both sides separately, and the adjustment is relatively complicated. In addition, the distance moved by the clamping plates on both sides must be equal during the adjustment process, otherwise the clamped formwork will shift to one side. When using multiple clamping mechanisms, it is difficult to keep the formwork as a whole level. At the same time, when rotating, it is necessary to rotate more circles to move the clamping plates to the desired position. The adjustment efficiency and clamping quality need to be further improved. Utility Model Content

[0006] By adopting the above technical solution, when the adjustable mechanism adjusts the position of the clamping plates, it only needs to rotate the turntable to achieve the position adjustment process of the two groups of clamping plates at the same time, without the need to adjust the two groups of clamping plates separately.

[0007] Furthermore, the turntable and the main gear are both fixedly connected to the rotating shaft, the screw is fixedly connected to the slave gear, and the rotating shaft and the screw are both rotatably connected to the side plate.

[0008] By adopting the above technical solution, when the turntable is rotated, the rotating shaft fixedly connected thereto and the main gear fixed on the rotating shaft will rotate smoothly, and when the slave gear rotates, the screw fixedly connected thereto rotates.

[0009] Furthermore, the main gear is meshed with the slave gear, and the diameter of the main gear is greater than the diameter of the slave gear.

[0010] By adopting the above technical solution, when the turntable rotates, the main gear will rotate along with it, driving the slave gear meshing with it to rotate.

[0011] Furthermore, the movable seat is threadedly connected to the screw rod, the movable seat is slidably connected to the limit rod, and the movable seat is fixedly connected to the clamping plate.

[0012] By adopting the above technical solution, when the screw rod rotates, the movable seat will move smoothly in the horizontal direction with the assistance of the limiting rod.

[0013] Furthermore, two groups of the movable seats are provided, and threaded holes are provided on both groups of the movable seats, and the threaded holes are symmetrically arranged.

[0014] By adopting the above technical solution, the symmetrically arranged moving seats and the symmetrically opened threaded holes, when the screw rod rotates, the two moving seats move in different directions.

[0015] Furthermore, the splints are provided in two groups, the two groups of splints are symmetrically arranged, and tooth plates are provided on the inner sides of the splints.

[0016] By adopting the above technical solution, two groups of clamping plates that are symmetrically arranged can clamp the cast-in-place formwork when the movable seats are close to each other.

[0017] Furthermore, a first fixing plate is provided on a side of the clamping plate away from the tooth plate, a second fixing plate is provided on a side of the top of the movable seat away from the clamping plate, and a support column is provided on the top of the second fixing plate.

[0018] By adopting the above technical solution, the arrangement of the first fixing plate, the second fixing plate and the supporting column can play a certain supporting role.

[0019] Furthermore, the first fixing plate is fixedly connected to the clamping plate, and the second fixing plate is fixedly connected to the movable seat.

[0020] By adopting the above technical solution, the first fixing plate is fixed to the end of the clamping plate, the second fixing plate is fixed to the moving seat, and the clamping plate and the moving seat provide support for the first fixing plate and the second fixing plate.

[0021] Furthermore, the support column is fixedly connected to the first fixing plate and the second fixing plate, and the support column is arranged at an angle.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model provides a turntable, a main gear, a slave gear, a screw and a moving seat. The adjustment process can be completed by rotating the turntable on one side of the side plate, without adjusting the two sides separately. When the turntable is rotated, the small-sized slave gear will rotate more circles under the drive of the large-sized main gear, so that the moving seat and the clamping plate and the tooth plate on the top of the moving seat and the tooth plate are adjusted to the position of clamping with the template more quickly. When the screw rotates due to the drive of the turntable, the main gear and the slave gear, the moving seats on both sides move the same distance to the middle at the same time, ensuring that the template remains level after clamping, thereby improving the adjustment efficiency and clamping quality to a certain extent.

[0027] 2. The utility model sets a first fixing plate, a second fixing plate and a support column. Since the clamping plate and the tooth plate are relatively long, in order to ensure that different positions in the vertical direction of the template are well clamped and fixed, the first fixing plate, the second fixing plate and the support column are required to assist in fixing the ends of the clamping plate and the tooth plate.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] A formwork casting fixture for civil engineering structures, such as Figure 1-Figure 4 As shown, it includes a clamp body 1, which includes a fixed seat 11 and a side plate 12. An adjustable mechanism 2 is arranged on the side plate 12. The adjustable mechanism 2 includes a rotating shaft 22, a screw 25 and a movable seat 27. A turntable 21 and a main gear 23 are arranged on the rotating shaft 22. A slave gear 24 is arranged at one end of the screw 25. Limit rods 26 are arranged on both sides of the screw 25. A clamp 3 is arranged on one side of the top of the movable seat 27. When the adjustable mechanism 2 adjusts the position of the clamp 3 and the tooth plate 4, it only needs to rotate the turntable 21 to simultaneously realize the position adjustment process of the two groups of clamps 3 and the tooth plate 4, and during the adjustment, it can be ensured that the distances of the two groups of clamps 3 and the tooth plate 4 approaching or moving away from the middle are equal. When multiple clamp bodies 1 are used to fix the horizontal direction of the cast-in-place formwork, it will not tilt due to the clamping center of the two groups of clamps 3 and the tooth plate 4 deviating from the center of the cast-in-place formwork.

[0037] See also Figure 2 , Figure 3 , Figure 4 The turntable 21 and the main gear 23 are both fixedly connected to the rotating shaft 22, the screw 25 is fixedly connected to the slave gear 24, and the rotating shaft 22 and the screw 25 are both rotatably connected to the side plate 12. When the turntable 21 is rotated, the rotating shaft 22 fixedly connected thereto and the main gear 23 fixed on the rotating shaft 22 will rotate smoothly. When the slave gear 24 rotates, the screw 25 fixedly connected thereto rotates. While the side plate 12 provides support for the adjustable mechanism 2, it will not affect the rotation of the rotating shaft 22 and the screw 25.

[0038] See also Figure 3 , Figure 4 The main gear 23 is meshed with the slave gear 24. The diameter of the main gear 23 is larger than that of the slave gear 24. When the turntable 21 rotates, the main gear 23 will rotate accordingly, driving the slave gear 24 meshed with it to rotate. Since the diameter of the main gear 23 is larger and the diameter of the slave gear 24 is smaller, the main gear 23 rotates one circle, which can make the slave gear 24 rotate multiple circles. Correspondingly, the screw 25 will also rotate more circles, so that the moving seat 27 moves a greater distance.

[0039] See also Figure 1 , Figure 3 , Figure 4 The movable seat 27 is threadedly connected to the screw rod 25, the movable seat 27 is slidably connected to the limiting rod 26, and the movable seat 27 is fixedly connected to the splint 3. When the screw rod 25 rotates, with the assistance of the limiting rod 26, the movable seat 27 will move smoothly in the horizontal direction, and the splint 3 fixed on the top of the movable seat 27 will also move accordingly, thereby changing the position of the splint 3 and fixing the casting template.

[0040] See also Figure 1 , Figure 3 , Figure 4 There are two groups of movable seats 27, both groups of movable seats 27 are provided with threaded holes, and the threaded holes are symmetrically arranged. The symmetrically arranged movable seats 27 and the symmetrically opened threaded holes enable the two movable seats 27 to move in different directions when the screw rod 25 rotates, and then approach or move away from each other at the same time, driving the clamping plate 3 and the tooth plate 4 on the top of the movable seat 27 to fix the cast-in-place formwork, or release the limiting and fixing effect on the cast-in-place formwork.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 There are two groups of clamps 3, which are symmetrically arranged. A tooth plate 4 is arranged on the inner side of the clamp 3. The two groups of symmetrically arranged clamps 3 can clamp the cast-in-place formwork when the moving seat 27 approaches each other. The surface of the tooth plate 4 is relatively rough and presents an uneven state. When clamping, the friction force can be increased, thereby ensuring the clamping effect.

[0042] Embodiment 2:

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A first fixing plate 5 is provided on the side of the splint 3 away from the tooth plate 4, a second fixing plate 6 is provided on the side of the top of the movable seat 27 away from the splint 3, and a support column 7 is provided on the top of the second fixing plate 6. The settings of the first fixing plate 5, the second fixing plate 6 and the support column 7 can play a certain supporting role. Because the splint 3 and the tooth plate 4 are relatively long, in order to ensure the fixing effect of the two on the cast-in-place formwork, their ends need to be supported and fixed by support columns 7, and the ends of the auxiliary splint 3 and the tooth plate 4 are kept on the same horizontal line with the other end.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The first fixed plate 5 is fixedly connected to the splint 3, and the second fixed plate 6 is fixedly connected to the moving seat 27. The first fixed plate 5 is fixed to the end of the splint 3, and the second fixed plate 6 is fixed to the moving seat 27. When the splint 3 moves with the moving seat 27, the first fixed plate 5 and the second fixed plate 6 also move accordingly, ensuring that the support column 7 always maintains a firm supporting and fixing effect on the ends of the splint 3 and the tooth plate 4.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The support column 7 is fixedly connected to the first fixed plate 5 and the second fixed plate 6. The support column 7 is arranged at an angle. The support column 7 fixed on the first fixed plate 5 and the second fixed plate 6 forms a stable triangle with the movable seat 27 and the clamping plate 3 to ensure that the support column 7 has a good fixing and clamping effect on the ends of the clamping plate 3 and the tooth plate 4, and ensures as much as possible that the clamping effect of the clamping plate 3 and the tooth plate 4 is stably exerted in the vertical direction of the cast-in-place formwork.

[0046] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 There are two groups of support columns 7, and each group of support columns 7 has two support columns. The two support columns 7 are symmetrically arranged. The two groups of support columns 7 can respectively make the ends of the two groups of clamping plates 3 and tooth plates 4 get better auxiliary fixation. Each group is provided with two symmetrical support columns 7, and then the two support columns 7 can be used to assist in fixing the ends of the same group of clamping plates 3 and tooth plates 4, thereby further ensuring the auxiliary fixation effect.

[0047] The implementation principle of the utility model is as follows: when it is necessary to fix the casting formwork, the turntable 21 is first rotated, so that the rotating shaft 22 and the main gear 23 outside the rotating shaft 22 rotate accordingly, and the meshing connection between the main gear 23 and the slave gear 24 drives the slave gear 24 and the screw 25 to rotate; when the screw 25 rotates, with the assistance of the limiting rods 26 on both sides, the two moving seats 27 are made to move relative to each other, so that the clamping plate 3 and the tooth plate 4 fixed on the moving seat 27 are close to each other until the clamping plate 3 and the tooth plate 4 clamp the cast-in-place formwork; when fixing, the first fixed plate 5, the second fixed plate 6 and the support column 7 support and fix the ends of the clamping plate 3 and the tooth plate 4, and always maintain their supporting effect during the movement of the clamping plate 3 and the tooth plate 4, and the auxiliary clamping plate 3 and the tooth plate 4 have a fixing effect on different vertical heights of the casting formwork.

[0048] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0049] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
