Technical Field

[0001] The utility model relates to the technical field of silo construction, and particularly relates to a formwork support for a silo. Background Technique

[0002] Silos are mainly built of reinforced concrete, and slip form construction is a common means in silo construction. The formwork is mainly lifted by a hydraulic lifting device to pour vertical concrete structures. The formwork mainly includes a lifting frame, a template and an operating platform, which climb on the support rods through a hydraulic device and rise together with the formwork. During the process of lifting the entire formwork, due to the large diameter of the silo, the platform is affected by its own gravity, load and friction with the concrete, etc., and the situation of template deformation is likely to occur. Specifically, the two correspondingly arranged templates on the formwork are deformed, the distance between the two templates is changed, and then the concrete silo wall poured is deformed and uneven. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides a formwork support for a silo, which solves the problem of formwork deformation in the prior art.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions:

The lifting frame includes a plurality of "冂"-shaped frames. The tops of the plurality of frames are connected by a cross bar. The frames below the cross bar are connected by a fixing rod. A fixing plate is horizontally arranged on the frame in the middle position. A jack is arranged on the fixing plate. A support rod is connected to the jack. Operating platforms are respectively arranged on both sides of the frame. The operating platforms are connected by a connecting rod. Templates are symmetrically arranged between the frames below the fixing plate.

[0007] Preferably, one end of the operating platform is connected and fixed by at least two vertical rods. The vertical rods are fixed to both sides of the frame.

[0008] Preferably, the vertical rod and the bottom of the operating platform are fixed by an inclined rod. The inclined rod and the operating platform are connected by a reinforcing rod.

[0009] Preferably, pads are respectively provided on both sides of the frame below the fixing rod, at least one guide rod is transversely passed through the pads, one end of the guide rod extending into the frame is connected to the template, and the guide rod and the pads are fixed by nuts.

[0010] Preferably, a telescopic rod is provided through the base plate, one end of the telescopic rod passes through the base plate and is fixed to the template, and one end of the telescopic rod is fixed at the center of the template.

[0014] The utility model has the following beneficial effects:

[0015] The utility model provides vertical rods on both sides of the lifting frame, and the operating platform is fixed on the vertical rods. At the same time, the vertical rods extend out of the top of the lifting frame and are connected and fixed by connecting rods. By connecting the operating platforms on both sides of the lifting frame with connecting rods, the force exerted on the lifting frame by the operating platforms is alleviated to a certain extent, and the lifting frame is prevented from being deformed by force, which in turn causes the distance between the two templates to change, resulting in inconsistent poured concrete dimensions and not meeting construction requirements. At the same time, the adjustable distance between the two templates can realize the adjustment of the silo wall thickness. BRIEF DESCRIPTION OF THE DRAWINGS

The tops of the plurality of frames 2 are connected by a cross bar 3, that is, a plurality of frames are sequentially connected on the cross bar, and the frames are parallel to each other, as Figure 2 shown. The frames 2 below the cross bar 3 are connected by fixing rods 4 to enhance the connection strength of the frames and provide support for the positioning cylinder at the same time. A fixing plate 5 is horizontally arranged on the frame 2 in the middle position. A jack 6 is arranged on the fixing plate 5. A support rod 7 is connected to the jack 6. Operation platforms 1 are respectively arranged on both sides of the frame 2, that is, the operation platforms are fixed on both sides of the lifting frame. The operation platforms 1 are connected by a connecting rod 8. Templates 9 are symmetrically arranged between the frames 2 below the fixing plate 5.

It should be noted that: one end of the operation platform 1 is connected and fixed by at least two vertical rods 12. The vertical rods 12 are fixed to both sides of the frame 2. The vertical rods 12 extend out of the top of the lifting frame and are connected by a connecting rod, that is, the connecting rod is located above the lifting frame. By arranging the vertical rods and the connecting rod, the operation platforms on both sides of the lifting frame are connected. Compared with directly connecting the operation platform to the lifting frame, this method alleviates the pressure on the lifting frame to a certain extent, alleviates the deformation of the lifting frame due to force problems to a certain extent, and further avoids the change in the distance between the two templates. According to needs, the vertical rods are connected by rods.

[0024] Furthermore, positioning cylinders 10 are respectively arranged on both sides of the fixing plate 5. The two ends of the positioning cylinder 10 are respectively abutted against the corresponding support rods 7. A cable 11 is penetrated through the positioning cylinder 10. The cable 11 passes through the fixing rod 4 and is locked and fixed by a nut. It should be noted that: the length of the positioning cylinder is adapted to the horizontal distance of the frame, further enhancing the strength of the lifting frame and avoiding the deformation of the frame towards its middle position.

[0025] Furthermore, the vertical rod and the bottom of the operating platform 1 are fixed via an oblique rod 13, and the oblique rod 13 and the operating platform 1 are connected via a reinforcing rod 14, thereby reinforcing and fixing the operating platform.

[0026] Furthermore, a backing plate 15 is provided on each side of the frame 2 below the fixing rod 4. At least one guide rod 16 is provided transversely through the backing plate 15. The end of the guide rod 16 extending into the frame 2 is connected to the template 9, and the guide rod 16 is secured to the backing plate 15 via nuts. It should be noted that the guide rods can be arranged in two rows, with multiple rods in each row, depending on the length of the template. The guide rods are secured to the backing plate via bolts, specifically nuts provided on the guide rods on both sides of the backing plate.

[0027] Furthermore, in order to adjust the distance between the two templates, a telescopic rod 17 is provided on the base plate 15, and one end of the telescopic rod 17 passes through the base plate 15 and is fixed to the template 9, and one end of the telescopic rod 17 is fixed at the center of the template 9. The telescopic rod includes but is not limited to an electric push rod, a hydraulic rod, and a cylinder.

[0028] Furthermore, a fence 18 is provided on the outside of the operating platform 1. Reinforcement ribs 19 are provided at the top corners of the frame 2.

[0029] In the utility model, when the jack crawls along the support rod, it moves upward with the lifting frame and the operating platform, a pouring cavity is formed between the two templates, and concrete is poured into the pouring cavity.
