Description

Technical Field

[0001] This utility model belongs to the field of building equipment technology, and specifically relates to a concrete column built-in steel casting mold. Background Technology

[0002] Composite slabs are a common construction material, formed by pouring concrete and reinforcing steel. They offer good overall integrity, with smooth top and bottom surfaces, facilitating finishing and making them suitable for high-rise and large-span buildings requiring high overall rigidity. The pouring process requires molds, which consist of cavities. The side walls of these cavities are provided with receiving grooves for placing the reinforcing steel. Since the length of the reinforcing steel exceeds the length of the cavity, and to facilitate placement, the receiving grooves are connected to the cavity and extend upwards to the top of the cavity's side walls.

[0003] For example, CN213674658U discloses a casting mold for steel-concrete composite slabs, including a base plate connected to a cavity. The cavity's sidewalls are provided with receiving grooves. A connecting cylinder surrounding the cavity is fixedly connected to the base plate. A limiting cylinder is rotatably connected to the base plate, with the connecting cylinder located inside the limiting cylinder. Multiple limiting blocks are provided along the circumferential direction on the sidewalls of the limiting cylinder, with the thickness of the limiting blocks gradually decreasing counterclockwise. The connecting cylinder is provided with sliding grooves corresponding to the sidewalls of the cavity. Limiting rods are slidably connected to the sliding grooves. One end of each limiting rod abuts against a limiting block, and the other end of each limiting rod is connected to a baffle for blocking the receiving grooves. In this application, simply rotating the limiting cylinder moves the limiting blocks connected to its sidewalls. The limiting blocks push their corresponding limiting rods towards the cavity, and the baffles block the receiving grooves, making adjustment more convenient.

[0004] However, it has been found in use that the above-mentioned existing technology has many inconveniences in using a spring to reset the baffle. Specifically, when the baffle closes the receiving groove, the spring is in a state of maximum contraction, so the spring has a large elastic force. When the limiting cylinder is rotated in the reverse direction, the spring will make the limiting rod press tightly against the limiting block, and the friction between the two will increase greatly. At this time, rotating the limiting cylinder in the reverse direction requires more force than rotating it in the forward direction. In addition, after repeated use, the spring will naturally weaken due to its own plastic rebound and need to be replaced. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a concrete column internal steel casting mold.

[0006] To achieve the above objectives, this utility model provides a concrete column built-in steel casting mold, including a cavity, receiving grooves symmetrically opened on the outer wall of the cavity, a positioning cylinder fixedly installed on the outer wall of the cavity, a rotating cylinder arranged outside the positioning cylinder, insert plates symmetrically slidably inserted on the outer wall of the positioning cylinder, a closing block fixedly connected to the end of the insert plate, and a toggle reset component arranged on the inner wall of the rotating cylinder.

[0007] The toggle reset assembly is used to drive the insert plate to move back and forth.

[0008] In the above technical solution, the toggle reset assembly further includes a drive block symmetrically fixed on the inner wall of the rotating cylinder. The bottom of the drive block is provided with an arc-shaped groove. A plug rod is fixedly connected to the other end of the plug plate and the plug rod is inserted into the arc-shaped groove.

[0009] In the above technical solution, a locking groove is further provided on the insert plate, and a uniformly distributed limiting block is fixedly connected in the locking groove. Insert blocks are symmetrically fixed in the positioning cylinder, and the insert blocks and the limiting blocks abut against each other.

[0010] In the above technical solution, the limiting block is further configured as an elastic structure.

[0011] In the above technical solution, a vertical cylinder is further provided outside the rotating cylinder, the rotating cylinder slides inside the vertical cylinder via a slide rail, a connecting block is fixedly connected to the top of the rotating cylinder, a connecting member is fixedly connected to the bottom of the connecting block, a rotating member is fixedly connected to the bottom of the connecting member, and both the connecting member and the rotating member rotate on the outer wall of the vertical cylinder.

[0012] In the above technical solution, the bottom of the rotating component is rotatably connected to a base, and the base is fixedly connected to the bottom of the vertical cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Rotating the rotating cylinder synchronously drives the drive block to rotate. Because the insert rod is in contact with the inner wall of the arc-shaped groove, and the shape of the arc-shaped groove gradually moves towards one side of the positioning cylinder, when the arc-shaped groove rotates with the rotating cylinder, the insert plate can only move in a straight line because it is limited by the positioning cylinder. Therefore, under the continuous compression of the arc-shaped groove, the insert rod will continuously push the insert plate to one side of the positioning cylinder to ensure that it is always inside the arc-shaped groove, thereby causing the sealing block to close the receiving groove. When the rotating cylinder is rotated in the opposite direction, the arc-shaped groove pulls the insert rod in the opposite direction, so that the insert plate can drive the sealing block away from the receiving groove. With the above structure, only the clockwise and counterclockwise rotation of the rotating cylinder are needed to move the insert plate closer to or away from the positioning cylinder, thereby completing the sealing and unsealing of the receiving groove. Compared with the existing technology, this structure does not require frequent replacement of the structure, and the force required for clockwise and counterclockwise rotation of the rotating cylinder is the same.

[0015] The block is always locked between two limiting blocks, which support and limit it. The limiting blocks are elastic structures that can deform and rebound. Therefore, when the force pushing the insert plate exceeds a certain threshold, the limiting blocks can allow the insert plate to move through deformation. With the above structure, during the movement of the insert plate on the positioning cylinder, the limiting blocks can accurately control the movement distance of the insert plate and provide it with locking capability. After the closing block closes the receiving groove, it can provide a certain support force and improve its locking capability.

[0016] By incorporating rotating components, connecting blocks, and other structural elements, the rotating cylinder in its rotating state does not act as a load-bearing structure. Therefore, it can be designed to be lighter, requiring less force to rotate. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-5The concrete column internal steel casting mold shown includes a cavity 7, with symmetrically symmetrically formed receiving grooves 13 on the outer wall of the cavity 7. A positioning cylinder 6 is fixedly installed on the outer wall of the cavity 7, and a rotating cylinder 9 is arranged outside the positioning cylinder 6. Insert plates 11 are symmetrically slidably inserted into the outer wall of the positioning cylinder 6, and a closing block 12 is fixedly connected to the end of the insert plate 11. A toggle reset assembly is arranged on the inner wall of the rotating cylinder 9. The toggle reset assembly is used to drive the insert plate 11 to reciprocate. The toggle reset assembly includes a drive block 10 symmetrically fixed on the inner wall of the rotating cylinder 9. An arc-shaped groove 14 is formed at the bottom of the drive block 10. An insert rod 15 is fixedly connected to the other end of the insert plate 11 and is inserted into the arc-shaped groove 14. Rotating the rotating cylinder 9 will synchronously drive the drive block 10 to rotate. Because the insert rod 15 fits against the inner wall of the arc-shaped groove 14, the arc-shaped groove 14... The shape gradually moves towards one side of the positioning cylinder 6. When the arc groove 14 rotates with the rotating cylinder 9, the insert plate 11 is limited by the positioning cylinder 6 and can only move in a straight line. Therefore, under the continuous compression of the arc groove 14, the insert rod 15 will continuously push the insert plate 11 towards one side of the positioning cylinder 6 to ensure that it is always inside the arc groove 14, thereby causing the sealing block 12 to seal the receiving groove 13. When the rotating cylinder 9 is rotated in the opposite direction, the arc groove 14 pulls the insert rod 15 in the opposite direction, so that the insert plate 11 can drive the sealing block 12 away from the receiving groove 13. With the above structure, only the clockwise and counterclockwise rotation of the rotating cylinder 9 is needed to make the insert plate 11 approach or move away from the positioning cylinder 6, thereby completing the sealing and unsealing of the receiving groove 13. Compared with the prior art, this structure does not require frequent replacement of the structure, and the force required for the clockwise and counterclockwise rotation of the rotating cylinder 9 is the same.

[0025] The insert plate 11 has a locking groove 16, and a uniformly distributed limiting block 18 is fixedly connected in the locking groove 16. The positioning cylinder 6 has symmetrically fixed insert blocks 17, and the insert blocks 17 and the limiting blocks 18 abut against each other. The limiting blocks 18 are set as elastic structures, and the insert blocks 17 are always locked between the two limiting blocks 18. The limiting blocks 18 support and limit it. The limiting blocks 18 are also elastic structures, which can deform and rebound. Therefore, when the force pushing the insert plate 11 exceeds a certain threshold, the limiting blocks 18 can allow the insert plate 11 to move through deformation. With the above structure, during the process of the insert plate 11 moving on the positioning cylinder 6, the limiting blocks 18 can accurately control the moving distance of the insert plate 11 and provide it with locking ability. After the closing block 12 closes the receiving groove 13, it can provide a certain support force and improve its locking ability.

[0026] A vertical cylinder 4 is provided on the outside of the rotating cylinder 9. The rotating cylinder 9 slides inside the vertical cylinder 4 via a slide rail 8. A connecting block 5 is fixedly connected to the top of the rotating cylinder 9, a connecting piece 3 is fixedly connected to the bottom of the connecting block 5, and a rotating piece 2 is fixedly connected to the bottom of the connecting piece 3. Both the connecting piece 3 and the rotating piece 2 rotate on the outer wall of the vertical cylinder 4. A base 1 is rotatably connected to the bottom of the rotating piece 2, and the base 1 is fixedly connected to the bottom of the vertical cylinder 4. By setting the rotating piece 2, the connecting block 5, and the connecting piece 3, the rotating cylinder 9 in the rotating state does not appear as a load-bearing structure, so it can be made lighter and requires less force to rotate.

[0027] Working principle:

[0028] Rotating the rotating cylinder 9 synchronously drives the drive block 10 to rotate. Because the insert rod 15 fits against the inner wall of the arc groove 14, and the shape of the arc groove 14 gradually moves towards one side of the positioning cylinder 6, when the arc groove 14 rotates with the rotating cylinder 9, the insert plate 11 is limited by the positioning cylinder 6 and can only move in a straight line. Therefore, under the continuous compression of the arc groove 14, the insert rod 15 will continuously push the insert plate 11 towards one side of the positioning cylinder 6 to ensure that it is always inside the arc groove 14, thereby causing the closing block 12 to close the receiving groove 13. When the rotating cylinder 9 is rotated in the opposite direction, the arc groove 14 pulls the insert rod 15 in the opposite direction, so that the insert plate 11 can drive the closing block 12 away from the receiving groove 13. With the above structure, only the clockwise and counterclockwise rotation of the rotating cylinder 9 is needed to make the insert plate 11 approach or move away from the positioning cylinder 6, thereby completing the closing and unclosing of the receiving groove 13. Compared with the prior art, this structure does not require frequent replacement of the structure, and the force required for the clockwise and counterclockwise rotation of the rotating cylinder 9 is the same.

[0029] Block 17 is always locked between two limiting blocks 18. The limiting blocks 18 support and limit it, and the limiting blocks 18 are elastic structures that can deform and rebound. Therefore, when the force pushing the insert plate 11 exceeds a certain threshold, the limiting blocks 18 can allow the insert plate 11 to move through deformation. With the above structure, during the process of the insert plate 11 moving on the positioning cylinder 6, the limiting blocks 18 can accurately control the moving distance of the insert plate 11 and provide it with locking ability. After the closing block 12 closes the receiving groove 13, it can provide a certain support force and improve its locking ability.

[0030] By setting up structures such as rotating component 2, connecting block 5, and connecting component 3, the rotating cylinder 9 in the rotating state does not appear as a load-bearing structure, so it can be made lighter and requires less force to rotate.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
