Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a building concrete formwork supporting structure. Background Art

[0002] As we all know, architectural concrete formwork refers to a complete set of structural systems for forming the newly poured concrete formwork and supporting the formwork. There are various different stage-by-stage classification methods for the formwork, which can be divided into two types according to the shape: flat formwork and curved formwork. It has a wide range of applications in the construction field.

[0003] Common building concrete formworks on the market need to be designed and installed on-site by workers before use. After use, the workers need to dismantle each formwork one by one. The process is time-consuming and labor-intensive, and the workers need to use tools to knock on the formwork to separate the formwork from the solidified concrete. Dismantling the formwork by knocking can easily damage the solidified concrete. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a building concrete formwork support structure, which is convenient for workers to disassemble the formwork, and the disassembly process saves time and effort, improves work efficiency, and does not cause damage to the solidified concrete.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a building concrete formwork support structure, including a support frame, a screw is connected to the middle part of the support frame by a thread, a connecting frame is rotatably installed at the bottom end of the screw, a turntable is provided at the top of the screw, a plurality of connecting rods are provided at the bottom end of the connecting frame, a fixing frame is provided at the bottom end of the connecting rod, two blocks opposite to each other with slots are provided on the outer wall of each side of the fixing frame, a formwork is installed inside the slot, a first connecting plate is provided at the top of each formwork, a second connecting plate is provided at the top of the first connecting plate, a stopper is provided on the inner side of each second connecting plate, and the thickness of the stopper gradually increases from bottom to top.

[0008] Furthermore, the length of the first connecting plate is greater than that of the second connecting plate.

[0009] Furthermore, the distance from the bottom end of the stopper to the bottom end of the second connecting plate is greater than the height of the blocking block.

[0010] Furthermore, the thickness of the first connecting plate matches the card slot.

[0011] Furthermore, the thickness of the second connecting plate is smaller than the width of the slot, and the sum of the thickness of the second connecting plate and the thickness of the top of the stopper is larger than the width of the slot.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a building concrete formwork support structure, which has the following beneficial effects:

[0014] The building concrete formwork support structure is provided with a fixing frame, a clamping block, a clamping slot and a first connecting plate. The fixing frame cooperates with the clamping slot on the clamping block to limit and support the position of the formwork, thereby facilitating the installation of the formwork. The second connecting plate, the blocking block, the fixing frame, the lead screw and the turntable are provided. The lead screw can be rotated by rotating the turntable. The rotation of the lead screw drives the fixing frame to rise. The blocking block blocks the rise of the fixing frame. As the fixing frame continues to rise, the blocking block is subjected to the force of the fixing frame to cause the top of the second connecting plate to expand outward, and then the top of the formwork is separated from the solidified concrete. There is no need to use the traditional knocking method to disassemble the formwork, so it is convenient for the staff to disassemble the formwork. The disassembly process saves time and effort, improves work efficiency, and does not cause damage to the solidified concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model is a building concrete formwork support structure, including a support frame 1, a screw 2 is connected to the middle part of the support frame 1 by a thread, a connecting frame 3 is rotatably installed at the bottom end of the screw 2, a turntable 4 is arranged at the top of the screw 2, and the screw 2 is convenient for rotating, a plurality of connecting rods 5 are arranged at the bottom end of the connecting frame 3, a fixing frame 6 is arranged at the bottom end of the connecting rod 5, and two card blocks 7 are arranged on the outer wall of each side of the fixing frame 6, and a template 9 is installed inside the card slot 8, and the card slot 8 limits the position of the template 9, and each template 9 is provided with a first card block 7 at the top end. Connecting plate 10, a second connecting plate 11 is arranged at the top end of the first connecting plate 10, and a stopper 12 is arranged on the inner side of each second connecting plate 11, and the thickness of the stopper 12 gradually increases from bottom to top. In the process of disassembling the formwork 9, rotating the turntable 4 can rotate the screw 2, and the rotation of the screw 2 drives the fixing frame 6 to rise, and the stopper 12 has a blocking effect on the rising of the fixing frame 6. As the fixing frame 6 continues to rise, the stopper 12 is subjected to the force of the fixing frame 6 to make the top of the second connecting plate 11 expand outward, and then the top of the formwork 9 is separated from the solidified concrete.

[0022] The length of the first connecting plate 10 is greater than that of the second connecting plate 11 , and when the clamping block 7 moves to the same height as the second connecting plate 11 , the clamping block 7 does not limit the second connecting plate 11 .

[0023] Among them, the distance from the bottom end of the stopper 12 to the bottom end of the second connecting plate 11 is greater than the height of the card block 7, and the card slot 8 and the first connecting plate 10 are aligned between the bottom end of the stopper 12 and the bottom end of the second connecting plate 11. The main function is to prevent the stopper 12 from interfering with the installation of the card slot 8 and the first connecting plate 10.

[0024] The thickness of the first connecting plate 10 matches the card slot 8 , and the first connecting plate 10 can be installed inside the card slot 8 .

[0025] The thickness of the second connecting plate 11 is smaller than the width of the slot 8 , and the sum of the thickness of the second connecting plate 11 and the thickness of the top of the stopper 12 is larger than the width of the slot 8 , so the stopper 12 can prevent the fixing frame 6 from rising.

[0026] To sum up, when using this kind of building concrete formwork support structure, the turntable 4 is rotated to rotate the screw 2, the fixed frame 6 is lowered to a suitable height, the slot 8 and the first connecting plate 10 are aligned between the bottom end of the stopper 12 and the bottom end of the second connecting plate 11, and then the fixed frame 6 is continued to be lowered, and the first connecting plate 10 is limited by the block 7 on the fixed frame 6, so as to support the formwork 9, and then concrete is injected into the inside of the formwork 9, the height of the concrete is lower than the height of the formwork 9, when the concrete solidifies, the turntable 4 can be rotated in the opposite direction to rotate the screw 2, and the rotation of the screw 2 drives the fixed frame 6 to rise, and the block 12 plays a role in blocking the rise of the fixed frame 6. As the fixed frame 6 continues to rise, the block 12 is subjected to the force of the fixed frame 6 to cause the top of the second connecting plate 11 to expand outward, and then the top of the formwork 9 is separated from the solidified concrete.
