Description

Technical Field

[0001] This utility model relates to the field of aluminum formwork support construction technology, specifically to an adjustable support device for aluminum formwork support. Background Technology

[0002] In the construction industry, aluminum formwork has gradually become a widely used formwork system in concrete pouring construction due to its advantages such as high strength, light weight, and high reusability. Currently, most aluminum formwork support structures on the market use traditional steel pipe coupler or adjustable screw types. These support structures have many drawbacks in actual construction. On the one hand, the assembly and disassembly process of traditional support structures is cumbersome, requiring workers to frequently tighten or loosen a large number of couplers and nuts, consuming significant manpower and time costs, seriously affecting construction efficiency. This inconvenience is particularly pronounced in large projects with tight schedules. On the other hand, traditional support structures have poor stability. During concrete pouring, due to insufficient reliability of their connections, they are prone to loosening and displacement, making it difficult to withstand large lateral pressures and construction loads, posing safety hazards. This could lead to serious quality and safety accidents such as formwork deformation, bulging, or even collapse, affecting project quality and construction safety.

[0003] Therefore, existing aluminum formwork support structures have obvious defects in terms of construction convenience and stability. There is an urgent need to develop a new type of aluminum formwork support structure that can effectively solve the problems of troublesome disassembly and poor stability, so as to meet the needs of efficient and safe building construction.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 7 An adjustable support device for aluminum formwork support is shown, comprising a support rod 1 and multiple support legs 2 for stabilizing the support rod 1. The tops of the multiple support legs 2 are hinged to a sliding ring 3, which is slidably mounted on the support rod 1. Multiple grooves 7 are provided circumferentially on the support rod 1, and multiple sliders adapted to the grooves 7 are provided inside the sliding ring 3, sliding within the grooves 7. The maximum displacement of the slider within the groove 7 is the range of motion of the sliding ring 3.

[0017] A rotating rod 4 is movably arranged between the support leg 2 and the support rod 1 to link the movements of multiple support legs 2. In this embodiment, a total of four rotating rods 4 are provided. The two ends of the rotating rod 4 are respectively hinged to the support leg 2 and the support rod 1. The support leg 2 and the support rod 1 are provided with slots for accommodating the rotating rods 4. When the support leg 2 is in the retracted state, the rotating rod 4 is located in the slot, which improves the compactness after retraction.

[0018] Multiple limiting components 6 are provided inside the support rod 1 to restrict the position of the sliding ring 3. In this embodiment, one or two limiting components 6 are provided. The limiting component 6 includes a limiting plate 60, a limiting block 61, and a second spring 62. Two limiting plates 60 are arranged opposite each other at intervals, and multiple second springs 62 are arranged between the two limiting plates 60. The two ends of the second springs 62 are respectively fixedly installed on the inner side of the two limiting plates 60. Two or more limiting blocks 61 are fixedly arranged on the other side of the limiting plate 60. One end of the limiting block 61 protrudes outward from inside the support rod 1. The limiting block 61 is cylindrical.

[0019] In this embodiment, two limiting blocks 61 are provided on the outer side of the limiting plate 60, and insertion holes adapted to the limiting blocks 61 are provided on both the support rod 1 and the sliding ring 3. When the upper limiting block 61 passes through the insertion hole on the support rod 1 and is inserted into the insertion hole on the sliding ring 3, the multiple support legs 2 are in a retracted state; when the lower limiting block 61 passes through the insertion hole on the support rod 1 and is inserted into the insertion hole on the sliding ring 3, the multiple support legs 2 are in an open state, and in this state, the device supports the aluminum template.

[0020] A telescopic rod 5 is adjustablely installed inside the support rod 1. Specifically, several adjustment holes are provided on the support rod 1 along its length, and a fixing hole is provided on the telescopic rod 5. After the length of the telescopic rod 5 extending beyond the top of the support rod 1 is adjusted, a pin 14 is used to pass through the adjustment holes and the fixing hole to fix the position of the telescopic rod 5. In a preferred embodiment, an adjustment post is threaded onto the top of the telescopic rod 5. The adjustment length of the adjustment post is not less than the interval between two adjacent adjustment holes, thereby improving the adjustment capability of the support range and achieving stable support for the aluminum template.

[0021] A handle 12 is provided on one side of the telescopic rod 5, and a vertical groove 13 is provided on one side of the support rod 1. One end of the handle 12 passes through the vertical groove 13 and is located on the outside of the support rod 1. The sliding of the handle 12 in the vertical groove 13 allows the adjustment hole to correspond to the fixing hole, which facilitates the installation of the rear pin 14 after adjusting the telescopic rod 5, and the exposed handle 12 is convenient for the operator to operate.

[0022] A balance bar 8 is adjustablely installed inside the support leg 2. One end of the balance bar 8 is located on the outside of the support leg 2. A support foot 9 is hinged to the exposed end of the balance bar 8. The support foot 9 increases the contact area with the ground, ensuring the stability of the support. A rubber pad 11 is fixedly installed at the bottom of the support foot 9 to improve the anti-slip ability of the support foot 9.

[0023] Multiple limiting holes are provided on the support leg 2, and an elastic limiting pin 10 is installed on the balance bar 8. The operator controls the elastic limiting pin 10 to be located in different limiting holes to adjust the extension length of the balance bar 8 to adapt to different uneven ground surfaces. Specifically, the elastic limiting pin 10 includes a limiting pin and a spring. A limiting groove is provided on the balance bar 8, and the limiting pin is slidably disposed in the limiting groove. The spring is disposed between the limiting groove and the limiting pin, and under the action of the spring, the limiting pin can be inserted into the limiting hole.

[0024] In use, the operator first presses one end of the two limiting blocks 61, bringing one end of the two limiting plates 60 closer together, causing the second spring 62 to contract until the two limiting blocks 61 move out of the sliding ring 7. At this point, the two limiting blocks 61 release the limiting effect on the sliding ring 7. The operator then moves the sliding ring 7 downwards, which in turn moves the four support legs 2 downwards. As the four support legs 2 move downwards, the four rotating rods 4 swing, allowing the four support legs 2 to open synchronously during the downward movement. Then, the operator presses the other end of the two limiting blocks 61 until the sliding ring 7 moves to the bottom of the several grooves 7. Then, the operator releases the pressing of the limiting blocks 61. At this point, under the rebound force of the second spring 62, the second spring 62 will squeeze the two limiting blocks 61, causing one end of both limiting blocks 61 to insert into the sliding ring 7. This limits the sliding ring 7, ensuring that all four support legs 2 can be opened at once without separate installation, and making storage and carrying convenient.

[0025] Subsequently, personnel can press the four elastic limit pins 10 according to the unevenness of the ground, so that the elastic limit pins 10 engage with the limit of the balance bar 8. The operator can then pull the balance bar 8 out of the support leg 2 to a suitable length, and then release the press of the elastic limit pins 10. Under the action of the spring rebound force, the elastic limit pins 10 move until one end of the elastic limit pin 10 is inserted into the corresponding limit hole. At this time, the elastic limit pins 10 can limit the balance bar 8, ensuring that personnel can adjust the extended length of the four balance bars 8 at will according to the unevenness of the ground, so that the support bar 1 can remain vertical and stable on the ground. At the same time, the four support legs 2 will not rotate, so that the support bar 1 can be supported more firmly and the stability of the support bar 1 can be guaranteed.

[0026] Finally, the operator can pull out the pin 14 and move the telescopic rod 5 through the handle 21 so that the top of the telescopic rod 5 is against the bottom of the aluminum template. At this time, the operator can pass the pin 5 through the corresponding adjustment hole and fixing hole to limit the telescopic rod 5 again, so that the telescopic rod 5 can support the aluminum template.

[0027] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
