Description

Technical Field

[0001] This utility model relates to an adjustable building formwork support device. Background Technology

[0002] In building construction, cast-in-place concrete structures rely on formwork systems for shaping. Reliable support structures must be installed beneath the formwork system to withstand the enormous loads generated during concrete pouring. Traditional support methods often employ cup-lock scaffolding or steel pipe coupler scaffolding. While these systems are widely used, they have several drawbacks: First, their assembly and dismantling are cumbersome, requiring numerous components and manpower, resulting in low efficiency. Second, their height adjustment precision is limited, making fine-tuning difficult and hindering the maintenance of flatness at the bottom of the formwork. Third, traditional support structures are unstable when standing independently, typically requiring connecting rods to form a unified structure for stability, making them inflexible in localized, small-scale, or complex space formwork operations.

[0003] Therefore, there is an urgent need for an adjustable building formwork support device that is quick to set up, easy to adjust, has good independent stability, and is suitable for various working conditions. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable building formwork support device.

[0005] To solve the above problems, the present invention adopts the following technical solution: An adjustable building formwork support device includes: The support block has symmetrical rotating seats on both sides of its side walls, and a mounting hole is vertically provided through the top of the support block. Side support rods are rotatably mounted via the rotating seat, and a fixing member is installed between the two side support rods to lock the two side support rods in place. A sleeve with a retaining ring at its upper end is inserted and fixed through the mounting hole. The retaining ring is located at the top of the support block, and the inner wall of the sleeve is provided with internal threads. A support rod is threadedly connected to the sleeve, and a support plate is provided at the upper end of the support rod, which supports the bottom of the cast-in-place formwork.

[0006] Preferably, the upper end of the side support rod is provided with a shaft tube, and the lower end of the side support rod is rotatably mounted with a ground plate, which makes planar contact with the ground. A rotation support is fitted between the shaft tube and the rotating seat.

[0007] Preferably, the rotating support is a double-ended bolt or a pin.

[0008] Preferably, a slot is provided on the outer wall of one side of the side support rod, and the fixing member is rotatably installed on the outer wall of the other side of the side support rod by means of a pin. The fixing member hooks into the slot on the outer wall of the other side of the side support rod, so that the opening angle of the two side support rods is restricted.

[0009] Preferably, the lower end of the side support rod is provided with a groove, and the upper end of the grounding plate is provided with a rotating block, and a second pin is installed between the rotating block and the groove.

[0010] Preferably, the bottom of the grounding plate is provided with anti-slip teeth to increase the friction between the ground and the ground.

[0011] Preferably, a radially penetrating force-applying hole is provided on the outer wall of the support rod near the bottom.

[0012] Preferably, right-angle grooves are provided on both sides of the top of the support block, and a connecting plate is installed between two adjacent adjustable building formwork support devices. The two ends of the connecting plate are inserted into the right-angle grooves, and a pin is inserted between the connecting plate and the right-angle groove.

[0013] The beneficial effects of this utility model are: One advantage is that this invention, through the adjustable-angle side supports and the central support rod, forms a stable triangular support structure between the ground and the template, exhibiting excellent mechanical properties. The grounding plate increases the contact area, and the anti-slip teeth effectively prevent slippage, greatly enhancing the independent stability of the device.

[0014] Secondly, the use of threaded support rods allows for stepless fine-tuning of the support height by rotating the rods. This simple and labor-saving operation enables precise control of the formwork's elevation and flatness, effectively ensuring the quality of concrete pouring.

[0015] Thirdly, the retaining ring design at the top of the casing provides double protection. Even if the weld joint fails due to long-term use or accidental impact, the retaining ring can effectively support the casing and the entire load above it, preventing sudden support failure and greatly improving construction safety.

[0016] Fourthly, the angle adjustment and locking mechanism of the side support rods is simple and intuitive, enabling rapid deployment and retraction, greatly improving the efficiency of formwork erection and dismantling. Its compact retracted state facilitates transportation and storage, making it ideal for formwork support operations within floors, in narrow spaces, or in complex structures.

[0017] Fifthly, the connecting plate can connect multiple adjacent support devices into a single unit, forming a stable support network, which further enhances the overall stability and anti-overturning ability of the entire support system under dynamic loads (such as the impact of concrete pouring).

[0025] See Figure 1 , Figure 2 and Figure 3 An adjustable building formwork support device is shown, comprising: The support block 1 has symmetrical rotating seats 11 on both sides of its side walls, and a mounting hole 12 is vertically provided through the top of the support block 1; the rotating seats 11 are fixed to the support block 1 by welding. Side support rod 2, the side support rod 2 is rotatably installed through the rotating seat 11, and a fixing member 3 is installed between the two side support rods 2 on both sides, and the two side support rods 2 are locked by the fixing member 3; The sleeve 4 has a retaining ring 41 at its upper end. The sleeve 4 is inserted and welded through the mounting hole 12. The retaining ring 41 is located at the top of the support block 1 to prevent the sleeve 4 from falling when the welding point of the sleeve 4 fails. The inner wall of the sleeve 4 is provided with internal threads. Support rod 5 is threadedly connected to sleeve 4. Support plate 51 is provided at the upper end of support rod 5, and the support plate 51 supports the bottom of cast-in-place formwork.

[0026] The formwork support method using this device is as follows: First, adjust the opening angle of the side support rods 2 on both sides according to the height of the top supported template, so that when the support rod 5 is rotated down to the low position, the height of the support plate 51 is slightly lower than the template. Lock the side support rods 2 on both sides with the fastener 3, and then adjust the support plate 51 to support the bottom of the template by rotating the support rod 5.

[0027] After the pouring is completed, rotate the support rod 5 so that the support plate 51 drops in height and detaches from the template. Then, lower the side support rod 2 and retract the two side support rods 2.

[0028] See Figure 2 As shown, the upper end of the side support rod 2 is provided with a shaft tube 21, and the lower end of the side support rod 2 is rotatably mounted with a ground plate 22. The ground plate 22 is in planar contact with the ground. A rotating support member 23 is fitted between the shaft tube 21 and the rotating seat.

[0029] The rotating support 23 is a double-ended bolt or a pin.

[0030] See Figure 2 As shown, a slot 211 is provided on the outer wall of one side of the side support rod 2. Multiple slots 211 are provided, and the opening of the slot 211 is inclined downward. The fixing member 3 is rotatably installed on the outer wall of the other side of the side support rod 2 by means of a pin. The fixing member 3 is a "door" shaped rod. The fixing member 3 hooks onto the slot 211 on the outer wall of the other side of the side support rod 2, so that the opening angle of the two side support rods 2 is restricted.

[0031] See Figure 2 As shown, the lower end of the side support rod 2 is provided with a slot 213, and the upper end of the ground plate 22 is provided with a rotating block 214. A second pin 215 is installed between the rotating block 214 and the slot 213.

[0032] The bottom of the grounding plate 22 is provided with anti-slip teeth 221, which increases the friction between the ground and the ground.

[0033] In the above technical solution, the design of the grounding plate 22 can increase the contact area with the ground and increase the stability of the device when it is assembled.

[0034] Together with the base plates 22 on both sides, and the support plate 51 at the top, they form an equilateral triangular support structure.

[0035] See Figure 2 As shown, a radially penetrating force-applying hole 551 is provided on the outer wall of the support rod 5 near the bottom.

[0036] The force application hole 551 is used to facilitate the application of rotational torque, so as to facilitate the rotation of the support rod 5.

[0037] See Figure 1 and Figure 4 As shown, right-angle grooves 111 are provided on both sides of the top of the support block 1, and connecting plates 6 are installed between two adjacent adjustable building formwork support devices. The two ends of the connecting plates 6 are inserted into the right-angle grooves 111, and pins 61 are inserted between the connecting plates 5 and the right-angle grooves.

[0038] Connecting multiple adjacent template support devices with connecting plates 6 can increase overall integrity and further improve stability.
