Description

Technical Field

[0001] The present application relates to the field of column formwork construction, and in particular to a column formwork structure and a construction process. Background Art

[0002] The frame structure is a commonly used reinforced concrete building structure, and the column is an important load-bearing structure of the frame structure. The column needs to be constructed through formwork. Specifically, it is necessary to tie the steel cage first, then assemble the column formwork, and finally pour concrete into the column formwork.

[0003] In the existing related technology, after the concrete used for constructing the column is poured into the column formwork, it is necessary to insert a vibrating rod from the top of the column formwork into the column formwork for vibration so as to expel the gas in the concrete, thereby reducing the internal stress remaining in the column when the concrete solidifies, and increasing the density of the concrete, thereby increasing the bearing capacity of the column.

[0004] With respect to the above-mentioned related technologies, for columns with a larger design bearing capacity, such as columns located at corners, the spacing between the steel bars in the steel cage is usually small, making it difficult for the vibrating rod to penetrate into the interior of the column formwork, which can easily lead to a problem of poor density. Summary of the invention

[0005] In order to facilitate the vibration of the concrete in the column formwork and ensure that the density of the concrete meets the design requirements, the present application provides a column formwork structure.

[0006] The column formwork structure provided in this application adopts the following technical solution: A column template structure, comprising a template body and a vibrating rod, wherein the template body encloses a column forming cavity, and the column forming cavity is used for column forming; A vibrating hole is formed through the side of the template body, the vibrating hole is connected with the column forming cavity, and the vibrating rod is movably matched with the vibrating hole in the horizontal direction.

[0007] By adopting the above technical solution, after the concrete is poured into the formwork body, the vibrating rod is inserted into the column forming cavity, so that the vibrating rod can directly extend into the interior of the concrete at the bottom and is not easily blocked by the multiple layers of steel bars on the top, thereby enabling the concrete at the bottom to be fully vibrated, which is beneficial to improving the density of the concrete column.

[0008] Furthermore, when the size of the column is relatively large, the vibrating rod can be extended into the middle of the column forming chamber in the horizontal direction, or reciprocating vibration can be performed in the horizontal direction, so that all parts of the column can be fully vibrated.

[0009] Optionally, the column template structure further includes an adjustment seat and a blocking member, the adjustment seat is penetrated by an adjustment hole, and the adjustment hole is connected to the vibration hole; The blocking piece is used to block the adjustment hole that is not provided with a vibrating rod, and the blocking piece is threadedly matched with the inner wall of the adjustment hole.

[0010] By adopting the above technical solution, the sealing performance of the thread is better. After the concrete is vibrated, the sealing piece is rotated and screwed into the adjustment hole, and then the adjustment hole is sealed by multiple turns of thread, so that the concrete is not easy to leak in large quantities from the inside of the column forming cavity.

[0011] Optionally, when the blocking piece blocks the adjustment hole, one end of the blocking piece is arranged flush with the inner wall of the column forming cavity.

[0012] The adoption of the above technical solution is helpful to ensure the flatness of the surface of the column after molding.

[0013] Optionally, the adjustment seat is provided with a first mark, and the blocking member is provided with a second mark, and when the blocking member blocks the adjustment hole, the first mark is aligned with the second mark.

[0014] By adopting the above technical solution, the setting of the first mark and the second mark is conducive to the construction personnel to judge whether the blocking piece is flush with the inner wall of the column forming cavity, thereby reducing the excessive rotation angle or too small rotation angle of the blocking piece, resulting in poor uneven flatness on the surface of the formed column.

[0015] Optionally, the blocking member is provided with a hand wheel.

[0016] By adopting the above technical solution, it is convenient for construction workers to rotate the blocking member.

[0017] Optionally, the column formwork structure further includes an adjustment seat and a blocking member, the adjustment seat is penetrated by an adjustment hole, the adjustment hole is connected to the vibrating hole, and the vibrating rod is threadedly engaged with the inner wall of the adjustment hole.

[0018] By adopting the above technical solution, when the vibrating rod needs to be adjusted in the horizontal direction, the vibrating rod can be moved in the horizontal direction by rotating the vibrating rod, which is helpful to ensure the sealing of the adjustment hole during the adjustment process.

[0019] Optionally, the vibration holes are located at the corners of the column formwork body.

[0020] By adopting the above technical solution, it is convenient to vibrate the concrete at the formed corners of the column, so that the concrete with poorer fluidity at the corners can be fully vibrated, thereby improving the density of the concrete column.

[0021] Optionally, the column template structure further includes an adjustment seat, the adjustment seat is penetrated by an adjustment hole, the adjustment hole is connected to the vibrating hole, and the adjustment hole can accommodate the vibrating rod; The adjusting seat slides in the vertical direction and is matched with an opening and closing valve plate. The opening and closing raft plate is used to open and close the adjusting chamber. The opening and closing raft plate is provided with an opening and closing inclined surface, and the opening and closing inclined surface is arranged away from the vibration hole. The opening and closing inclined surface of the opening and closing raft plate will move in the vertical direction under the action of horizontal force.

[0022] By adopting the above technical solution, when the vibrating rod needs to be pulled out after the vibration is completed, the regulating hole can be closed in time by opening and closing the raft plate, thereby reducing the large amount of concrete leakage. In addition, when the vibrating rod needs to be inserted into the regulating hole, the regulating hole can be temporarily closed.

[0023] In addition, the present application further provides a column formwork construction process, which is implemented through the above-mentioned column formwork structure and includes the following steps: S1, making steel cage; S2, assembling the template body; S3, inserting the vibrating rod into the column forming cavity, and then making the vibrating rod vibrate and reciprocate in the horizontal direction.

[0024] The adoption of the above technical solution is conducive to ensuring that the concrete in each part of the column forming cavity is fully vibrated.

[0025] Optionally, in step S1, the steel cage is provided with a stirrup widening portion, and the height of the stirrup widening portion corresponds to the height of the vibrating rod.

[0026] By adopting the above technical solution, it is easy to reduce the collision between the vibrating rod and the stirrups of the steel cage.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the concrete is poured into the formwork body, the vibrator is inserted into the column forming cavity, so that the vibrator can directly extend into the interior of the concrete at the bottom, and is not easily blocked by the multi-layer steel bars on the top, so that the concrete at the bottom can be fully vibrated, which is conducive to improving the density of the concrete column; Furthermore, when the size of the column is large, the vibrating rod can be extended into the middle of the column forming chamber in the horizontal direction, or reciprocated in the horizontal direction to make all parts of the column fully vibrated. 2. The thread has good sealing performance. After the concrete is vibrated, the plugging piece is screwed into the adjustment hole, and then the adjustment hole is blocked by multiple turns of thread, so that the concrete is not easy to leak from the inside of the column forming cavity; 3. When the vibrating rod needs to be adjusted in the horizontal direction, the vibrating rod can be moved in the horizontal direction by rotating the vibrating rod, which is helpful to ensure the sealing of the adjustment hole during the adjustment process.
