[0026] Embodiment 1

[0027] As Figures 1 to 4 shown;

[0028] A shear wall formwork support device includes a main body 1 of a steel bar frame and first templates 11 arranged on both sides of the main body 1 of the steel bar frame;

[0029] In this implementation: After investigation, the publication (announcement) number: CN218375277 discloses a shear wall formwork support device. However, when installing the formwork, it is possible that the distance between the formworks on both sides and the steel bars is different, resulting in the shear wall shifting from the expected position after pouring, rendering the shear wall unusable and requiring re-pouring. To solve this technical problem, a limit component 2 and an auxiliary component 3 are added on this basis.

[0030] Furthermore:

[0031] As Figures 1 to 4 shown;

[0032] Combined with the above content:

[0033] To make the distance between the formwork and the steel bars the same, this shear wall formwork support device further includes a limit component 2 provided inside the first formwork 11;

[0034] The limit component 2 includes a positioning block 22 and a screw rod 24 fixed on the surface of the positioning block 22. The screw rod 24 penetrates the surface of the first formwork 11, and a limit groove 21 matching the positioning block 22 is provided on the first formwork 11. The positioning block 22 slides on the surface of the first formwork 11 through the limit groove 21. A screw sleeve 23 is rotated at the position of the first formwork 11 corresponding to the screw rod 24. The screw sleeve 23 is threadedly connected to the screw rod 24. A chute A is provided on the adjacent side of the two first formworks 11. Second formworks 28 are provided on one side of the two first formworks 11. The two second formworks 28 are slidably connected to the first formworks 11 through the chute.

[0035] In this implementation: When pouring the shear wall, first fix the main body 1 of the steel bar rack on the ground, place the two positioning seats 25 on both sides of the main body 1 of the steel bar rack, push the two first formworks 11 towards the main body 1 of the steel bar rack to make them fit with the main body 1 of the steel bar rack, and then apply force to the screw sleeve 23. The screw sleeve 23 will rotate inside the first formwork 11 through the rotating shaft, and the screw rod 24 threadedly connected to the screw sleeve 23 will move towards the main body 1 of the steel bar rack inside the first formwork 11, and the positioning block 22 rotatably connected to the screw rod 24 will slide inside the positioning block 22.

[0036] Even further:

[0037] In an alternative embodiment, the screw sleeve 23 is made of a transparent material, and a scale table is engraved on the surface of the screw rod 24.

[0038] In this embodiment: Due to the fact that the screw sleeve 23 is made of a transparent material and a scale table is engraved on the surface of the screw rod 24, the rotation of the screw rod 24 to an appropriate position can be observed through the screw sleeve 23.

[0039] Even further:

[0040] In an alternative embodiment, a positioning seat 25 is provided on the surface of the first template 11. A sliding bar is integrally formed on the surface of the first template 11. A chute B matching the sliding bar is formed on the surface of the positioning seat 25. The first template 11 and the positioning seat 25 are slidably connected through the sliding bar and the chute B, and the positioning seat 25 is fixedly connected to the ground by bolts.

[0041] In this embodiment: When the screw sleeve 23 is rotated, due to the fact that the positioning block 22 is in contact with the main body 1 of the steel bar frame, it will slide in the positioning seat 25 in a direction away from the main body 1 of the steel bar frame until the distance between the two first templates 11 is controlled to be equal, and then the positioning seat 25 is connected and fixed to the ground by bolts.

[0042] Furthermore:

[0043] In an alternative embodiment, several limiting blocks 27 are fixedly connected to the surface of each first template 11 away from the main body 1 of the steel bar frame, and a support rod 26 is rotatably connected to the upper surface of each positioning seat 25 through a connecting seat.

[0044] In this embodiment: Then, a force is applied to the support rod 26, and the support rod 26 will rotate on the upper surface of the positioning seat 25 and tilt towards the first template 11 until the limiting ball 31 contacts the bottom surface of the limiting block 27. The limiting block 27 will limit the limiting ball 31, and the limiting ball 31 will cause the sliding rod 32 to slide into the support rod 26, and the spring 33 will be compressed.

[0045] Furthermore:

[0046] In an alternative embodiment, an auxiliary component 3 is further included and disposed inside the support rod 26;

[0047] A spring 33 is installed inside the support rod 26, and a sliding rod 32 is also installed inside the support rod 26. Both ends of the spring 33 are in contact with the support rod 26 and the sliding rod 32. The end of the sliding rod 32 away from the support rod 26 is movably connected to a limiting ball 31. A positioning groove 35 is formed inside the limiting block 27, the limiting ball 31 is inserted into the positioning groove 35, and a button 34 is inserted into the positioning groove 35. The button 34 is slidably connected to the limiting block 27.

[0048] In this embodiment: After the support rod 26 is tilted to a certain angle, the spring 33 will push the limit ball 31 into the positioning groove 35 due to elastic potential energy, and the button 34 will slide upward inside the positioning groove 35 under the force, thus realizing the limit of the first template 11. Then, find a second template 28 with an appropriate length, insert the second template 28 into the two first templates 11 from top to bottom, and then flip the screw sleeve 23 to make the positioning block 22 on the same parallel line as the first template 11, and then it can be poured. When it needs to be disassembled after use, press the button 34 downward, and use the button 34 to squeeze the limit ball 31 out of the positioning groove 35, and then the first template 11 can be slid in the direction away from the main body of the steel bar frame 1.

[0049] It should be noted that the sliding rod 32 is movably connected to the limit ball 31 through a ball socket, preventing the sliding rod 32 from not sliding due to different force application points when the button 34 applies force to the limit ball 31.

[0050] Working principle and usage process of the utility model: When it is necessary to pour shear walls, first fix the main body 1 of the steel bar rack on the ground, place two positioning seats 25 on both sides of the main body 1 of the steel bar rack, push two first templates 11 towards the main body 1 of the steel bar rack to make them fit with the main body 1 of the steel bar rack. Then apply force to the screw sleeve 23. The screw sleeve 23 will rotate inside the first template 11 through the rotating shaft. The screw rod 24 threadedly connected to the screw sleeve 23 will move towards the main body 1 of the steel bar rack inside the first template 11. The positioning block 22 rotatably connected to the screw rod 24 will slide inside the positioning block 22. Due to the fact that the screw sleeve 23 is made of transparent material and the surface of the screw rod 24 is engraved with a scale table, the rotation of the screw rod 24 to an appropriate position can be observed through the screw sleeve 23. When the screw sleeve 23 is rotated, due to the fact that the positioning block 22 fits with the main body 1 of the steel bar rack, it will slide away from the main body 1 of the steel bar rack inside the positioning seat 25 until the distances between the two first templates 11 are controlled to be equal. Then connect and fix the positioning seat 25 to the ground with bolts. Then apply force to the support rod 26. The support rod 26 will rotate on the upper surface of the positioning seat 25 and tilt towards the first template 11 until the limiting ball 31 contacts the bottom surface of the limiting block 27. The limiting block 27 will limit the limiting ball 31. The limiting ball 31 will cause the sliding rod 32 to slide into the support rod 26, and the spring 33 will be compressed. Until the support rod 26 tilts to a certain angle, the spring 33 will push the limiting ball 31 into the positioning groove 35 due to its elastic potential energy, and the button 34 will be forced to slide upwards inside the positioning groove 35, thus realizing the limitation of the first template 11. Then find a second template 28 of appropriate length, insert the second template 28 into the two first templates 11 from top to bottom. Then flip the screw sleeve 23 to make the positioning block 22 on the same parallel line as the first template 11, and then it can be poured. When it needs to be disassembled after use, press the button 34 downwards, and use the button 34 to squeeze the limiting ball 31 out of the positioning groove 35, then the first template 11 can be slid away from the main body 1 of the steel bar rack.
