Technical Field
[0001] The utility model relates to the technical field of concrete pouring, in particular to a concrete formwork with an interception function. Background Technique
[0002] Concrete formwork is an indispensable part of construction projects, mainly used to control the shape and quality of concrete during the concrete pouring process. It can be fixed at the construction site and used to support concrete components, prevent the concrete from deforming or shifting during early hardening, and ensure the smoothness and flatness of the concrete surface.
[0003] However, in the current existing technology, when pouring concrete for walls and columns, the concrete grades used for the walls and columns are different. In order to ensure the effect of concrete, it is necessary to isolate the pouring of concrete with different grades. In the past, isolation was achieved by fixing a wire mesh to the column reinforcement. However, due to its weak binding force and the too low strength of ordinary wire (sheet) mesh, when the concrete is poured from top to bottom to the root of the wall, the impact force is too large, and the wire (sheet) mesh cannot block the huge impact force when pouring the concrete, and it will collapse immediately during the concrete pouring and cannot play an effective isolation role. Content of the Utility Model

[0010] As a preferred solution of the present utility model, after the steel plate is embedded in the positioning groove, the hole groove on the outer wall corresponds to the bump in the positioning groove, and the bump extends out of the cavity and is embedded in the hole groove and abuts against the inner wall of the hole groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, this application adopts an auxiliary component.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Embodiment
[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a concrete formwork with an interception function, including formwork 1. An auxiliary component for interception during concrete pouring is arranged inside the formwork 1. The auxiliary component includes a positioning groove 2 arranged on the inner wall of the formwork 1 for positioning the position and angle during the installation of the steel plate 5. A plurality of cavities 3 are arranged on the inner wall of the positioning groove 2 for accommodating the convex blocks 4. Springs 301 and convex blocks 4 are arranged inside each of the plurality of cavities 3. The springs 301 are used to support the convex blocks 4 and push them out of the cavities 3. When the steel plate 5 is slidably installed, through the conical surface at the bottom cooperating with the arc angle of the convex blocks 4, the convex blocks 4 can be extruded to shrink into the cavities 3, ensuring that the steel plate 5 can pass through smoothly. A steel plate 5 is arranged inside the positioning groove 2. The steel plate 5 can replace the conventional wire mesh to isolate the formwork 1, and the self-strength of the steel plate 5 can improve the isolation effect. The steel bar distribution layout is carried out by using BIM technology to deepen the steel plate 5 to ensure no collision. A plurality of holes 501 are arranged on the outer wall of the steel plate 5. Through the conical structure at the bottom of the steel plate 5 and the positioning groove 2, the angle can be restricted during the insertion of the steel plate 5. At the same time, in cooperation with the convex blocks 4 being embedded into the holes 501 on the outer wall of the steel plate 5, it assists in correcting the angle of the steel plate 5 to ensure the sealing effect after the installation of the steel plate 5. And because the steel plate 5 and the formwork 1 are installed by sliding, it is convenient to disassemble the formwork 1 after concrete pouring. A plurality of anchor bolts 502 are arranged on both sides of the steel plate 5 to deepen the stud bolts of the steel plate 5 and increase the contact area with the concrete, which can prevent the concrete from cracking; the steel plate 5 is fixed by arc welding of profiled steel.
[0021] For the embodiment, please refer to Figures 1-4, the positioning groove 2 is located on the inner wall of the openings on both sides of the formwork 1 for the column, and the formwork 1 for the column communicates with the formwork 1 for the wall through the openings on both sides. A plurality of the cavities 3 are longitudinally arrayed on the inner wall of the positioning groove 2. One end of the convex block 4 is located in the cavity 3 and is slidably connected to the inner wall of the cavity 3. Both ends of the spring 301 are connected to the inner wall of the cavity 3 and the convex block 4 by welding. The convex block 4 is pushed out of the cavity 3 by the spring 301. Both the convex block 4 and the hole groove 501 on the outer wall of the steel plate 5 are arc-shaped structures. Both the bottom of the steel plate 5 and the positioning groove 2 are tapered structures. The steel plate 5 can be embedded in the positioning groove 2 and is slidably connected to the positioning groove 2. After the steel plate 5 is embedded in the positioning groove 2, the hole groove 501 on the outer wall corresponds to the convex block 4 in the positioning groove 2. The convex block 4 extends out of the cavity 3 and is embedded in the hole groove 501 and abuts against the inner wall of the hole groove 501. A plurality of the anchor bolts 502 are arranged in an orderly manner on the outer wall of the steel plate 5 and are connected to the outer wall of the steel plate 5 by welding. The steel bar penetrates through the steel plate 5 and extends into the formwork 1. During use, first, the formwork 1 is spliced, and then the steel plate 5 is inserted into the specified position in the formwork 1 through the positioning groove 2 of the formwork 1. At the same time, through the tapered structures at the bottom of the steel plate 5 and the positioning groove 2, the angle during the insertion of the steel plate 5 is positioned. After the steel plate 5 is inserted, the convex block 4 is pushed out of the cavity 3 by the spring 301 and extends into the hole groove 501 on the outer wall of the steel plate 5, thereby correcting the angle of the steel plate 5. Then, the concrete is poured into the formwork 1, and at the same time, the concrete is isolated by the steel plate 5. After the concrete is poured and dried, the formwork 1 is removed.
[0022] The working process of the present utility model: During use, first, the formwork 1 is spliced, and then the steel plate 5 is inserted into the specified position in the formwork 1 through the positioning groove 2 of the formwork 1. At the same time, through the tapered structures at the bottom of the steel plate 5 and the positioning groove 2, the angle during the insertion of the steel plate 5 is positioned. After the steel plate 5 is inserted, the convex block 4 is pushed out of the cavity 3 by the spring 301 and extends into the hole groove 501 on the outer wall of the steel plate 5, thereby correcting the angle of the steel plate 5. Then, the concrete is poured into the formwork 1, and at the same time, the concrete is isolated by the steel plate 5. After the concrete is poured and dried, the formwork 1 is removed. The present utility model uses a steel plate to isolate the concrete instead of a wire mesh, improving the isolation effect, increasing the contact area between the steel plate and the concrete to prevent the concrete from cracking, and ensuring the quality of the concrete pouring.
