Description

Technical Field

[0001] The utility model relates to the field of building formwork support, in particular to a concrete column formwork support device. Background Art

[0002] Formwork support columns are special iron parts used to support and fix the formwork of concrete components in construction projects. They are often used in construction projects such as house construction, bridge engineering, basements, etc. Their main function is to support the formwork and concrete components, ensure the accurate size and shape of the concrete components, and thus ensure the quality of the construction project.

[0003] The existing support formwork of the column is mainly fixed by a plurality of U-shaped limit frames when supporting and fixing. When fixing, the head and tail ends of the adjacent reinforcement rods of the limit frames are plugged in and fixed, and a wedge-shaped positioning plug is used for plugging. However, when installing and fixing the U-shaped limit frames, the U-shaped limit frames are mainly tightened and fixed by friction fit with the back of the formwork. However, this fixing method makes the U-shaped limit frames easy to loosen, and the spacing between the limit frames cannot be evenly adjusted up and down, which affects the supporting effect of the limit frames. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a concrete column formwork supporting device.

[0005] The utility model is realized through the following technical solutions:

[0006] A concrete column formwork support device includes multiple outer formworks on the outside of the concrete column. The outer parts of the multiple outer formworks are supported and fixed by multiple U-shaped limit frames. The multiple U-shaped limit frames are positioned and installed by adjusting the upper and lower spacing through positioning components during installation. The positioning components include multiple rotating insertion connection mechanisms arranged on the U-shaped limit frames. The rotating insertion connection mechanisms are inserted into multiple positioning sockets on the support rod connected to the back of the outer formwork for adjustment and fixation.

[0007] Further optionally, the U-shaped limit frame includes four reinforcement rods and sliding sleeves fixed at their tails. Adjacent reinforcement rods are combined and connected by inserting their head ends into the sliding sleeves of another reinforcement rod. A positioning block is inserted into the multiple strip holes opened at the head end of the reinforcement rod for limiting.

[0008] Further optionally, each rotating insertion connection mechanism includes a hanging rod inserted into the reinforcement rod, one end of the hanging rod extends to the outside of the reinforcement rod and is fixed to the toggle block, the side of the toggle block is provided with a compression spring sleeved on the hanging rod, the other end of the hanging rod is connected and fixed to a limit strip, and the limit strip can be stored in a storage groove opened on the side of the reinforcement rod.

[0009] Further optionally, a plurality of positioning jack cards are evenly arranged on the outside of the support rod, and the positioning jacks include circular jacks and connected strip holes, and the strip holes match the shape of the limiting strips.

[0010] Further optionally, a plurality of reinforcement rods are evenly fixed on the back of the outer formwork.

[0011] Further optionally, a plurality of rotational insertion connection mechanisms are evenly distributed on the four reinforcement rods.

[0012] Compared with the existing technology, the beneficial effect of the utility model is: the utility model installs a rotating insertion connection mechanism on multiple U-shaped limit frames of the column outer template, and the rotating insertion connection mechanism is inserted into the positioning socket opened on the support rod connected to the back of the outer template for adjustment and fixation.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] like Figure 1 As shown, a concrete column formwork support device includes multiple outer formworks 1 on the outside of the concrete column. The outsides of the multiple outer formworks 1 are supported and fixed by multiple U-shaped limit frames. The multiple U-shaped limit frames are positioned and installed by adjusting the upper and lower spacing through positioning components during installation. The positioning components include multiple rotating insertion connection mechanisms arranged on the U-shaped limit frames. The rotating insertion connection mechanisms are inserted into several positioning holes on the support rod 2 connected to the back of the outer formwork 1 for adjustment and fixation. The U-shaped limit frame is positioned and fixed by the rotating insertion connection mechanism to prevent it from falling off from the back of the outer formwork 1.

[0019] like Figure 1 , 2As shown, the U-shaped limit frame includes four reinforcement rods 3 and sliding sleeves 4 fixed at their tail ends. The adjacent reinforcement rods 3 are assembled and connected by inserting their head ends into the sliding sleeves 4 of another reinforcement rod 3. A positioning block 5 is inserted into a plurality of strip holes opened at the head end of the reinforcement rod 3 for limiting. The positioning block 5 is wedge-shaped and can be driven into the strip hole to adjust the tightness.

[0020] like Figure 2 , 3 As shown, each rotating insertion connection mechanism includes a hanging rod 6 inserted in the reinforcement rod 3, one end of the hanging rod 6 extends to the outside of the reinforcement rod 3 and is fixed to the toggle block 7, and a compression spring 8 sleeved on the hanging rod 6 is arranged on the side of the toggle block 7. The other end of the hanging rod 6 is connected and fixed with a limit strip 9, and the limit strip 9 is in the same direction as the toggle block 7 for easy adjustment of the rotational insertion in the later stage. The limit strip 9 can be stored in the storage groove 12 opened on the side of the reinforcement rod 3. When not installed, the compression force of the compression spring 8 pushes the toggle block 7 to drive the hanging rod 6 to deviate to the outside of the reinforcement rod 3, so that the limit strip 9 will be stored in the storage groove 12 to avoid interference between the limit strip 9 and the support rod 2. At the same time, when the limit strip 9 is inserted into the bar hole 10 and rotated and engaged, the compression spring 8 puts the limit strip 9 in a tensioned state to prevent it from rotating freely.

[0021] like Figure 3 As shown, a plurality of positioning jack cards are evenly arranged on the outside of the support rod 2 , and the positioning jacks include a circular jack 11 and a connected strip hole 10 , and the strip hole 10 matches the shape of the limiting strip 9 .

[0022] A plurality of reinforcement rods 3 are evenly fixed on the back of the outer formwork 1 .

[0023] A plurality of rotating insertion connection mechanisms are evenly distributed on the four reinforcement rods 3 .

[0024] The implementation principle of a concrete column formwork support device in the embodiment of the present application is:

[0025] When installing the U-shaped limit frame (the inner steel bars of the outer formwork 1 of the column have been tied), one of the reinforcing rods 3 of the U-shaped limit frame is attached to the outer side of the outer formwork 1 and aligned with the corresponding positioning socket, and the multiple rotating insertion connection mechanisms on the reinforcing rod 3 are operated for plugging;

[0026] When operating the rotary insertion connection mechanism, hold the toggle block 7 with your hand and rotate it to keep it in a vertical state and press down the hanging rod 6. The limiting strip 9 at the front end of the hanging rod 6 is inserted along the bar hole 10 of the positioning socket, and the hanging rod 6 enters the socket 11. After entering, the toggle block 7 rotates 90 degrees. In this way, the limiting strip 9 rotates and gets stuck in the support rod 2 of the outer template 1, so as to pre-fix the reinforcement rod 3. After pre-fixation, the head end of another adjacent reinforcement rod 3 is inserted into the sliding sleeve 4 of the pre-fixed reinforcement rod 3, and then the rotary insertion connection mechanism is operated to connect. After multiple cycles, the overall pre-fixation of the U-shaped limiting frame is realized, and finally the positioning plug block 5 is inserted and clamped;

[0027] After the first U-shaped limit frame is fixed, the remaining U-shaped limit frames can be adjusted and fixed in spacing according to the multiple positioning holes on the support rod 2. This adjustment and fixation is more convenient and efficient, and the spacing is uniform and each U-shaped limit frame is better stressed. At the same time, the U-shaped limit frame will not fall off the outer formwork 1. After the concrete of the outer formwork 1 of the column is poured and solidified, the U-shaped limit frames are disassembled one by one, and the reverse operation is used to rotate the insertion connection mechanism to remove the reinforcement rod 3 from the support rod 2 of the outer formwork 1.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
