Description

Technical Field

[0001] The utility model relates to the technical field of template construction, in particular to an assembled movable template support frame for cast-in-place concrete. Background Art

[0002] In recent years, with increased national investment in infrastructure and a surge in real estate development projects, the construction industry has shown sustained growth. A global construction boom is sweeping the globe, particularly in developing countries, and the promotion of prefabricated buildings has become a key development direction for the transformation and upgrading of the national construction industry. With strong national support, prefabricated buildings have become a major trend in the construction industry. The rapid development of the construction industry and the widespread use of cast-in-place concrete have led to a strong market demand for formwork composite structural supports. With the advancement of formwork technology, formwork support systems are also becoming increasingly diverse. The formwork support systems in my country mainly include coupler-type steel pipe scaffolding, bowl-hook-type scaffolding, door-type scaffolding, disc-hook-type scaffolding, etc. However, the mainstream of the formwork support system is still occupied by coupler-type steel pipe scaffolding. This system is still used for internal and external scaffolding in domestic construction. Although this system is recognized by the public, due to the blind pursuit of low prices by material-using units and malicious competition in the scaffolding market, there are currently no products that fully meet national standards on domestic construction sites, which is also one of the reasons for the frequent accidents in the current formwork support system. On the other hand, because its locking adopts coupler type, it is greatly affected by the quality of the coupler itself and manual operation.

[0003] After searching, the Chinese patent application number 202321979778.2 discloses a mobile formwork support device, including a base frame, the bottom of the base frame is evenly provided with walking wheels, the four sides of the base frame are provided with fixed support mechanisms, the top of the base frame is provided with lower branch pipes in a matrix, the upper ends of the lower branch pipes are slidably provided with upper branch pipes, the upper ends of the lower branch pipes are provided with bolt and nut mechanisms for locking or releasing the lower branch pipes with the upper branch pipes, the upper ends of the upper branch pipes are fixedly provided with end pipes, the interior of the end pipes is provided with screws, the upper ends of the end pipes are provided with nuts threadedly assembled on the outside of the screws, and the upper ends of the screws are rotatably provided with brackets;

[0004] Although the above-mentioned patent can move on the ground through the walking wheels at its bottom, and after moving to the designated position, the chassis can be fixedly supported by the fixed support mechanism to ensure the stability of the chassis and provide stable support for the formwork, there are still the following deficiencies in the use process: 1. When the chassis is moved to the position where it is needed to be used through the walking wheels, the user needs to control the screw rod to rotate by turning the handle in sequence to adjust the height of the chassis, so that the chassis contacts the ground, and thus the walking wheels are away from the ground. The operation is relatively complex and not convenient to improve the convenience of use; 2. After the chassis is placed at the use position, due to its small contact area with the ground, the stability of the chassis is poor.

[0005] Therefore, there is an urgent need for an assembled mobile formwork support for cast-in-place concrete to solve the above problems. Summary of the Utility Model

[0024] As Figures 1-3 shown, a kind of assembled mobile formwork support for cast-in-place concrete proposed in this embodiment includes a base 100 and support rods 101 fixedly connected to the top wall of the base 100. Two to five groups of support rods 101 are evenly distributed along the top wall of the base 100. A group of limiting plates 102 are fixedly connected to the side walls of two groups of support rods 101. Two groups of limiting plates 102 are symmetrically arranged about the central axis of the base 100. A moving component is connected to the inner wall of the limiting plate 102. The moving component includes slide bars 103 slidably connected to the inner wall of the limiting plate 102. Two groups of slide bars 103 are symmetrically arranged about the central axis of the limiting plate 102. Universal wheels 104 are fixedly connected to the bottom walls of the slide bars 103. A heightening component is connected to the outer wall of the support rod 101. By sliding the slide bars 103 on the inner wall of the limiting plate 102, the convenience of use is improved.

[0025] As Figures 1-5 shown, as a preferred implementation manner, on the basis of the above manner, further, a mounting plate 110 is fixedly connected to the top wall of the base 100. An adjusting screw 111 is rotatably connected to the bottom wall of the mounting plate 110. A connecting frame 112 is threadedly connected to the outer wall of the adjusting screw 111. The connecting frame 112 is also fixedly connected to the four groups of slide bars 103. The height of the universal wheels 104 can be adjusted synchronously under the action of the adjusting screw 111, making the use more convenient.

[0026] As Figures 1-4As shown, as a preferred embodiment, on the basis of the above method, further, the height-adjusting component includes a height-adjusting plate 120 slidably connected to the outer wall of the support rod 101. The inner wall of the support rod 101 is provided with uniformly distributed first mounting grooves 121, and the inner wall of the height-adjusting plate 120 is provided with uniformly distributed second mounting grooves 122. The first mounting grooves 121 and the second mounting grooves 122 cooperate with each other. The height of the height-adjusting plate 120 can be adjusted under the action of the first mounting grooves 121 and the second mounting grooves 122, which is beneficial to improving work efficiency.

[0027] As Figures 1-3 shown, as a preferred embodiment, on the basis of the above method, further, the four groups of height-adjusting plates 120 are fixedly connected by a support plate 123. A limit bolt 124 is connected between the first mounting groove 121 and the second mounting groove 122. A fixing nut 125 is threadedly connected to the outer wall of the limit bolt 124. After the limit bolt 124 passes through the first mounting groove 121 and the second mounting groove 122, the firmness of the height-adjusting plate 120 after adjustment is improved.

[0028] As Figures 1-2 shown, as a preferred embodiment, on the basis of the above method, further, a rotating rod 126 is rotatably connected to the inner wall of the height-adjusting plate 120. A bracket 127 is fixedly connected to the top wall of the rotating rod 126. A locking bolt 128 is threadedly connected to the inner wall of the height-adjusting plate 120. The locking bolt 128 cooperates with the rotating rod 126. The inner wall of the base 100 is provided with uniformly distributed leveling grooves 129. A stabilizing plate 130 is slidably connected to the inner wall of the base 100. Two groups of the stabilizing plates 130 are symmetrically arranged about the central axis of the base 100. A fixing bolt 131 is threadedly connected to the top wall of the base 100. The fixing bolt 131 cooperates with the stabilizing plate 130. The leveling grooves 129 can adapt to different construction environments, and further improve the stability of the base 100.

[0029] Specifically, when the assembled mobile formwork support for cast-in-place concrete is in use: First, move the base 100 to the position where it is needed through the universal wheels 104. After that, drive the connecting frame 112 to move upward by rotating the adjusting screw 111. Through the connecting frame 112, drive the four groups of sliding rods 103 to slide upward at the same time. Through the sliding rods 103, drive the universal wheels 104 away from the ground and make the base 100 contact with the ground. When the ground is uneven, turn the leveling bolt in the leveling groove 129 to improve the stability of the base 100. Then loosen the fixing nut 125 and pull out the limit bolt 124 from the first installation groove 121 and the second installation groove 122. Install the cylinder on the mounting plate 110. Through the output end of the cylinder, push the supporting plate 123 and drive the four groups of height-adjusting plates 120 to move upward at the same time. When the height to be adjusted is relatively large, align the first installation groove 121 and the second installation groove 122 and then insert the limit bolt 124. Then remove the cylinder from the mounting plate 110 and replace it with a cylinder with a larger stroke to achieve the adjustment of the height of the height-adjusting plate 120, making the operation more convenient. Since the positions of different formworks are different, loosen the locking bolt 128 and then rotate the bracket 127 to correspond to the formwork, and tighten the locking bolt 128 to improve the diversity of use. Then pull out the stabilizing plate 130 from the base 100 and fix the stabilizing plate 130 by tightening the fixing bolt 131, thereby improving the overall stability of the device.
