Description

Technical Field

[0001] This utility model relates to the field of structural column technology, specifically to a column top mold for casting structural columns. Background Technology

[0002] Structural columns refer to reinforced concrete structural columns that should be installed in the walls of multi-story brick-concrete structures to enhance the integrity and stability of the building. These columns are connected to the ring beams of each floor to form a spatial frame that can resist bending and shearing, and are an effective measure to prevent the building from collapsing.

[0003] A search revealed that in patent publication number CN216893490U, a standardized structural column mold for secondary masonry structural columns, it was proposed that "the standardized structural column mold for secondary masonry structural columns allows manual rotation of a limiting rod that is sleeved with a fixed shaft, causing the limiting rod to engage with the limiting groove opened by the fixed rod. Ultimately, the four sets of vertical plates are fixed together by the limiting groove opened by the limiting rod and the fixed rod. Then, concrete is poured into the rectangular cavity formed by the four sets of vertical plates using a pouring hopper. After the concrete has solidified, the limiting rods that are engaged with the limiting grooves of each set are manually rotated upwards, causing all the limiting rods of the fixed vertical plates to separate, and each set of vertical plates can be disassembled individually. Compared with the traditional integral structural mold, the separation of the structural column from the mold is more convenient."

[0004] However, the above solution still has some shortcomings in actual use. In the above solution, concrete is poured into the rectangular cavity formed by four sets of vertical plates by manual operation. After the concrete is formed, the limiting rods of each set that are locked in the limiting groove are manually rotated upwards to separate all the limiting rods of each set of fixed vertical plates and disassemble each set of vertical plates individually. However, in the above solution, there are four sets of vertical plates, and the four sets of vertical plates are individual units. Therefore, the operator needs to repeat the same four sets of actions to fix the vertical plates, resulting in low efficiency of installing building formwork. Utility Model Content

[0005] This utility model provides a column top mold for casting structural columns to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a column top mold for casting structural columns, including a drive box, a drive device is provided inside the drive box, a top cover is movably engaged with the top of the drive box, a horizontal groove is provided inside the top cover, and a baffle structure is slidably connected to the top cover through the horizontal groove.

[0007] The driving device includes a movable ring and a screw. The bottom end of the movable ring is slidably connected to the inner wall of the driving box, and an abutment plate is fixedly installed on the inner wall of the movable ring.

[0008] The screw is rotatably connected to the inner wall of the drive box via a built-in motor. A threaded block is threaded onto the surface of the screw, and a hinge rod is hinged to the top of the threaded block. The other end of the hinge rod is fixedly connected to the outer side of the movable ring.

[0009] The baffle structure includes a vertical plate, a vertical rod is fixedly installed at the bottom end of the vertical plate, and an overlapping plate is fixedly installed on the outside of the vertical rod, with the overlapping plate located below the top cover.

[0010] Furthermore, a base plate is placed at the top of the top cover, and the base plate is located between the inner sides of the four vertical plates.

[0011] Furthermore, the inner wall of the drive box is provided with an annular groove, and the bottom end of the movable ring extends into the interior of the annular groove and overlaps with the inner wall of the annular groove.

[0014] Compared with the prior art, the present invention provides a column top mold for casting structural columns, which has the following beneficial effects:

[0015] The column top mold of this cast-in-place structural column is equipped with a driving device and a baffle structure.

Under the action of the contact plate, the overlapping plate pushes the vertical plate together and apart. The entire process is mechanized, avoiding manual operation. This saves time and effort during the forming process of the column top mold, thereby improving the forming efficiency of the column top mold. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model discloses a column top mold for casting structural columns, including a drive box 1. The drive box 1 is equipped with a drive device 3 inside. The top of the drive box 1 is movably connected to a top cover 2. The top cover 2 has a horizontal groove 201 inside. The top cover 2 is slidably connected to a baffle structure 4 through the horizontal groove 201.

[0024] The driving device 3 includes a movable ring 301 and a screw 303. The bottom end of the movable ring 301 is slidably connected to the inner wall of the driving box 1, and an abutment plate 302 is fixedly installed on the inner wall of the movable ring 301.

[0025] The screw 303 is rotatably connected to the inner wall of the drive box 1 via a built-in motor. A threaded block 305 is threadedly connected to the surface of the screw 303. A hinge rod 306 is hinged to the top of the threaded block 305. The other end of the hinge rod 306 is fixedly connected to the outer side of the movable ring 301.

[0026] The baffle structure 4 includes a vertical plate 401, a vertical rod 402 is fixedly installed at the bottom end of the vertical plate 401, and an overlapping plate 403 is fixedly installed on the outside of the vertical rod 402. The overlapping plate 403 is located below the top cover 2.

[0027] By setting up a drive device 3 and a baffle structure 4, the screw 303 included in the drive device 3 causes the hinge rod 306 to rotate the contact plate 302 on the inner side of the movable ring 301 through the threaded block 305, so that the contact plate 302 begins to contact the overlapping plate 403 below the vertical plate 401, causing the overlapping plate 403 to push the vertical plate 401 to close and separate under the action of the contact plate 302. The entire process is mechanized, avoiding manual operation, which saves time and effort in the forming process of the column top mold, thereby improving the forming efficiency of the column top mold.

[0028] Specifically, a base plate 5 is placed at the top of the top cover 2, and the base plate 5 is located between the inner sides of the four vertical plates 401.

[0029] In this embodiment, the base plate 5 can gradually fit into the four vertical plates 401, and the cavity formed by the four vertical plates 401 and the base plate 5 is the casting cavity.

[0030] Specifically, the inner wall of the drive box 1 is provided with an annular groove, and the bottom end of the movable ring 301 extends into the interior of the annular groove and overlaps with the inner wall of the annular groove.

[0031] In this embodiment, the annular groove allows the movable ring 301 inside the drive box 1 to rotate stably.

[0032] Specifically, a gear 304 is fixedly sleeved on the surface of the screw 303, and a mounting bracket 307 is fixedly installed on the inner wall of the drive box 1. A positioning rack 308 is slidably connected to the top of the mounting bracket 307 through an electric push rod. The positioning rack 308 is located behind the gear 304.

[0033] In this embodiment, the electric push rod can drive the positioning rack 308 to gradually mesh with the gear 304, so that the gear 304 is restricted by the positioning rack 308, and the gear 304 will be locked together with the screw 303, so that the screw 303 is limited, and the screw 303 can drive the threaded block 305 to move to the designated position and then lock it, thereby allowing the movable ring 301 to rotate to the designated position.

[0034] Specifically, the contact plate 302 and the overlapping plate 403 are at the same height, and the slope of the contact plate 302 is opposite to the slope of the overlapping plate 403.

[0035] In this embodiment, the contact plate 302 will gradually come into contact with the overlapping plate 403, so that the slope of the contact plate 302 will fit with the slope of the overlapping plate 403, causing the overlapping plate 403 to move the vertical plate 401 inside the transverse groove 201 under the push of the contact plate 302, causing the four vertical plates 401 to gradually close together.

[0036] When in use, first place the base plate 5 on the top cover 2, and then drive the four baffle structures 4 to move closer to each other through the drive device 3;

[0037] The built-in motor inside the drive box 1 can drive the screw 303 to rotate, and the rotation of the screw 303 will drive the threaded block 305 to move in the axial direction. The threaded block 305 drives the movable ring 301 to rotate inside the drive box 1 through the hinge rod 306, and the contact plate 302 on the inner side of the movable ring 301 will move in a circle with the midpoint of the movable ring 301 as the center.

[0038] During the movement of the contact plate 302, the contact plate 302 will gradually come into contact with the overlapping plate 403, so that the slope of the contact plate 302 will fit with the slope of the overlapping plate 403, causing the overlapping plate 403 to drive the vertical plate 401 to move inside the transverse groove 201 under the push of the contact plate 302, causing the four vertical plates 401 to gradually close together.

[0039] This allows the four vertical plates 401 to gradually fit together with the base plate 5. Then, the operator pours concrete into the cavity formed by the four vertical plates 401 and the base plate 5, ultimately forming a cast-in-place structural column.

[0040] In summary, the column top mold of this cast-in-place structural column, by setting up a driving device 3 and a baffle structure 4, utilizes the screw 303 included in the driving device 3 to drive the hinge rod 306 to rotate the contact plate 302 on the inner side of the movable ring 301 through the threaded block 305, so that the contact plate 302 begins to contact the overlapping plate 403 below the vertical plate 401, causing the overlapping plate 403 to push the vertical plate 401 to close and separate under the action of the contact plate 302. Moreover, the entire process is carried out by mechanized operation, avoiding manual operation, which saves time and effort in the forming process of the column top mold, thereby improving the forming efficiency of the column top mold.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
