Description

Technical Field

[0001] This utility model relates to the field of steel formwork technology that can be precisely connected, specifically a steel formwork that can be precisely connected. Background Technology

[0002] Steel formwork is a steel formwork used for concrete pouring and shaping. It is widely used in construction projects because of its reusability and the aesthetically pleasing results of concrete pouring.

[0003] For example, a type of steel formwork with the authorization announcement number "CN221320672U" allows for precise docking. The docking block aligns with the docking groove, causing a limiting bead to compress a limiting spring. The limiting spring then engages the limiting bead with the limiting groove. Next, the two ends of the installation strip move downwards within the sliding groove. Once in the appropriate position, installation bolts are inserted into the threaded holes to restrict the position of the installation strip, thus enabling stable docking of the steel formwork with another steel formwork. This method requires only a small number of installation bolts to complete the assembly, improving the efficiency of road and bridge construction. However, in practice, the docking of the two steel formworks uses a spring and steel bead for fixation. Since the steel bead cannot retract, the docked steel formwork cannot be disassembled, preventing reuse and limiting its usability. This restricts the normal use of the steel formwork. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the limitations in the use of steel formwork and the impact on its normal use, and to propose a steel formwork that can be precisely connected.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a steel formwork that can be precisely connected, including a vertical plate and a horizontal plate. The left side of the horizontal plate is fixedly connected to the right side of the horizontal plate, respectively. The upper and lower sides of the outer wall of the vertical plate are respectively processed with openings. A square plate is fixedly connected to the inner wall of the opening. The inner wall of the square plate is connected to a butt joint structure. A support structure is connected to the rear of the inner wall of the vertical plate.

[0007] Preferably, the docking structure includes a vertical rod and a square frame. The outer wall of the vertical rod is slidably connected to the inner wall of the square plate. The end of the vertical rod is fixedly connected to the inner side of the square frame. Straight plates are fixedly connected to the left and right sides of the inner wall of the square frame. A spring is sleeved on the outer wall of the vertical rod. The two ends of the spring are fixedly connected to the outer wall of the square frame and the outer wall of the square plate, respectively.

[0008] Preferably, the outer wall of the square frame is inserted into the inner wall of the opening.

[0009] Preferably, the outer wall of the cross plate matches the inner diameter of the opening.

[0010] Preferably, the support structure includes a concave plate and a vertical cylinder. The rear end face of the concave plate is fixedly connected to the rear of the inner wall of the vertical plate. The inner wall of the concave plate is rotatably connected to the upper part of the outer wall of the vertical cylinder. A screw is threadedly connected to the inner wall of the vertical cylinder.

[0011] Preferably, the rear end face of the vertical cylinder is adjacent to the rear of the inner wall of the vertical plate.

[0012] The present invention proposes a steel formwork that can be precisely connected. The beneficial effects are as follows: Through the connection structure, a hand is inserted into the square frame, with fingers gripping the straight plate. Then, the straight plate moves outwards, carrying the square frame. The moving square frame, along with the vertical rod, moves outwards through the square plate. Simultaneously, the square frame compresses a spring. Then, the horizontal plate on the left side of the second vertical plate is inserted into the slot on the right side of the first vertical plate. Next, the straight plate is released, and the spring, losing its tension, provides a rebound force, causing the square frame to move inwards with the vertical rod. The outer wall of the vertical rod then inserts into the round opening on the outer wall of the horizontal plate, completing the vertical plate connection. This eliminates the limitations of using steel formwork and ensures its normal operation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] Please see Figure 1-4In this embodiment, a steel template that can be precisely connected includes a vertical plate 1 and a horizontal plate 5. The left side of the horizontal plate 1 is fixedly connected to the right side of the horizontal plate 5 at the top and bottom respectively. The upper and lower sides of the outer wall of the vertical plate 1 are respectively processed with openings 4. The inner wall of the openings 4 is fixedly connected to a square plate 6. The inner wall of the square plate 6 is connected to a docking structure 2. The rear of the inner wall of the vertical plate 1 is connected to a support structure 3.

[0021] The docking structure 2 includes a vertical rod 201 and a square frame 202. The outer wall of the vertical rod 201 is slidably connected to the inner wall of the square plate 6. The vertical rod 201 slides up and down through the inner wall of the square plate 6 under force. The end of the vertical rod 201 is fixedly connected to the inner side of the square frame 202. Straight plates 204 are fixedly connected to the left and right sides of the inner wall of the square frame 202 respectively. A spring 203 is sleeved on the outer wall of the vertical rod 201. The two ends of the spring 203 are fixedly connected to the outer wall of the square frame 202 and the outer wall of the square plate 6 respectively. After the square frame 202 moves outward under force, it rebounds through the elastic force of the spring 203. The outer wall of the square frame 202 is inserted into the inner wall of the opening 4.

[0022] By inserting a hand into the square frame 202 through the docking structure 2, with fingers gripping the straight plate 204, the straight plate 204 moves the square frame 202 outward. The moving square frame 202, along with the vertical rod 201, moves outward through the square plate 6. Simultaneously, the square frame 202 compresses the spring 203. Then, the horizontal plate 5 on the left side of the second upright plate 1 is inserted into the slot 4 on the right side of the first upright plate 1. Next, the straight plate 204 is released, and the spring 203 loses its tension and provides a rebound force, causing the square frame 202 to move inward along with the vertical rod 201. The outer wall of the vertical rod 201 is then inserted into the round opening on the outer wall of the horizontal plate 5, completing the docking of the upright plates 1. This eliminates the limitations of using steel formwork and ensures the normal use of steel formwork.

[0023] The outer wall of the horizontal plate 5 matches the inner diameter of the opening 4. The support structure 3 includes a concave plate 301 and a vertical cylinder 302. The rear end face of the concave plate 301 is fixedly connected to the rear of the inner wall of the vertical plate 1. The inner wall of the concave plate 301 is rotatably connected to the upper part of the outer wall of the vertical cylinder 302. The vertical cylinder 302 rotates under force through the pin on the inner wall of the concave plate 301. The inner wall of the vertical cylinder 302 is threaded with a screw 303. The screw 303 rotates up and down under force through the inner wall of the vertical cylinder 302. The rear end face of the vertical cylinder 302 is adjacent to the rear of the inner wall of the vertical plate 1.

[0024] Working principle:

[0025] Steel formwork joint;

[0026] Insert your hand into the square frame 202, with your fingers gripping the straight plate 204. Then, move the square frame 202 outward using the straight plate 204. The moving square frame 202, along with the vertical rod 201, moves outward through the square plate 6. At the same time, the square frame 202 compresses the spring 203. Then, insert the horizontal plate 5 on the left side of the second upright plate 1 into the slot 4 on the right side of the first upright plate 1. Next, release the straight plate 204. The spring 203 loses its tension and provides a rebound force, causing the square frame 202 to move inward with the vertical rod 201. This allows the outer wall of the vertical rod 201 to be inserted into the round opening on the outer wall of the horizontal plate 5, completing the docking of the upright plates 1. Both the horizontal plate 5 and the slot 4 are pre-machined on the outer wall of the upright plate 1. The horizontal plate 5 can be directly inserted into the slot 4, achieving precise docking.

[0027] Steel formwork enclosure and support:

[0028] The two upright plates 1 are joined together at a 90-degree angle. Then, the vertical cylinder 302 is rotated outward through the pin shaft on the inner wall of the concave plate 301. Next, the screw 303 is rotated downward through the inner wall of the vertical cylinder 302, increasing the length of the screw 303 and the vertical cylinder 302, so that the bottom of the screw 303 can be inserted into the ground. This will support the upright plate 1. The other two positions are installed in the same way to support the upright plate 1. At this time, the four upright plates will form a square. Then, mortar is poured into this space of the upright plates.

[0029] Example 2:

[0030] Please see Figure 1-4 In this embodiment, a steel template that can be precisely connected also includes handles 7, with the outer sides of the two handles 7 being fixedly connected to the left and right sides of the inner wall of the upright plate 1, respectively.

[0031] Working principle:

[0032] By grasping the handle 7 and lifting it upwards, the upright plate 1 can be lifted and moved. The handle 7 facilitates the movement of the upright plate 1.
