AI Technical Summary
In existing methods for pouring concrete at the top of structural columns, removing excess concrete at the flared end is time-consuming and labor-intensive, affecting construction quality.
The formwork is made by pouring concrete at the top of the column using a socket-type formwork. The width of the formwork can be adjusted by using movable baffles and telescopic rods. The flared opening can be opened to pour concrete and then closed to avoid removing excess concrete.
This eliminates the need to remove excess concrete from the flared end of the concrete structural column after it has been formed, saving materials and time and improving construction efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, specifically a socket-type column top casting template. Background Technology
[0002] The commonly used method for pouring concrete at the top of structural columns is to set a funnel at the top of the structural column formwork, through which the concrete enters the formwork. However, this method has some problems. For example, after the concrete structural column is poured and formed, the excess concrete at the funnel needs to be removed. The removal process will affect the construction quality of the structural column. After the removal is completed, the removed surface also needs to be repaired, which is time-consuming and labor-intensive.
[0003] This patent is an invention to solve the above-mentioned problems, namely, a socket-type column end casting formwork. The casting formwork is flared, allowing concrete to be poured into the structural column formwork when opened. After pouring, the flared opening is closed, and the casting formwork can be reused as the size of the structural column changes. There is no excess concrete at the flared opening, so there is no need for concrete removal after the structural column is formed, saving concrete materials, time, and labor, and offering good practicality.
[0004] Therefore, we propose a socket-type column top casting formwork. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a socket-type column top casting template, which has the advantages of adjustable width according to changes in the size of the structural column during use, reusability, no excess concrete at the flared end, and therefore no need for concrete removal after the structural column is formed, saving concrete materials, time and labor, and good practicality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a socket-type column top casting template, including a fixed baffle, a control rod movable groove is provided on the upper outer side of the fixed baffle, and a baffle control rod is slidably provided inside the control rod movable groove, and a movable baffle is fixedly provided on the outer side of the baffle control rod, and the movable baffle is in contact with the inner wall of the fixed baffle.
[0007] Preferably, the upper and lower parts of the fixed baffle are both fixedly provided with telescopic rod assemblies, and the two ends of the telescopic rod assemblies are provided with nuts that rotate spirally, and the nuts are in contact with the outer side of the fixed baffle.
[0008] Preferably, the control lever movable groove is an arc-shaped groove.
[0009] Preferably, the lower part of the movable baffle is rotatably connected to the outer ends of both ends of the telescopic rod assembly.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, by setting a movable baffle, forms a funnel shape for the casting template. When the movable baffle is open, concrete can be poured into the structural column template. After the pouring is completed, the funnel shape can be closed to continue casting. The width can be adjusted according to the size of the structural column and can be reused. There is no excess concrete at the funnel shape. Therefore, after the structural column is formed, there is no need to remove the concrete, which saves concrete materials, time and labor, and has good practicality. Attached Figure Description

[0017] 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.
[0018] like Figures 1 to 4 As shown, this utility model provides a socket-type column top casting template, including a fixed baffle 5. A control rod movable groove 4 is provided on the upper outer side of the fixed baffle 5, and a baffle control rod 2 is slidably provided inside the control rod movable groove 4. A movable baffle 1 is fixed on the outer side of the baffle control rod 2, and the movable baffle 1 is in contact with the inner wall of the fixed baffle 5. When the concrete is poured, when the concrete surface is flush with the surface of the movable baffle 1 and the grout is fully discharged, the baffle control rod 2 is slid inside the control rod movable groove 4, and the control rod movable groove 4 is arc-shaped. The template is closed and locked at the end of the control rod movable groove 4. After curing, the template is removed. After cleaning, the component can be reused, so that the width can be adjusted according to the size of the structural column during use and it can be reused.
[0019] Specifically, telescopic rod assemblies 3 are fixedly installed on the upper and lower parts of the fixed baffle 5, and nuts are spirally rotated at both ends of the telescopic rod assembly 3. The nuts are attached to the outer side of the fixed baffle 5. This assembly is inserted into the supported structural column template. The template width is adjusted by the telescopic rod assembly 3, thereby adjusting the distance between the fixed baffles 5.
[0020] Furthermore, the shape of the control rod movable groove 4 is an arc groove. When the concrete surface is flush with the surface of the movable baffle 1 and the grout is fully discharged, the baffle control rod 2 slides inside the control rod movable groove 4. The shape of the control rod movable groove 4 is an arc groove. The mold is closed and locked at the end of the control rod movable groove 4. After curing, the mold is removed.
[0021] Furthermore, the lower part of the movable baffle 1 is rotatably connected to the outer ends of the telescopic rod assembly 3. When the telescopic rod assembly 3 extends or retracts, the lower part of the movable baffle 1 slides on the outer side of the telescopic rod assembly 3.
[0022] Working principle: When using this component, the operator first inserts it into the pre-supported structural column formwork. The width of the formwork is adjusted using the telescopic rod component 3, thereby adjusting the distance between the fixed baffles 5. The operator then checks whether the movable baffle 1 is loose and whether the formwork is tightly sealed. Concrete pouring begins. When the concrete surface is flush with the movable baffle 1 and sufficient grout has leaked out, the baffle control rod 2 slides inside the control rod movable groove 4, which is an arc-shaped groove. The formwork is then closed and locked at the end of the control rod movable groove 4. After curing, the formwork is removed. After cleaning, the component can be reused. This allows for width adjustment as the structural column size changes during use, and it is reusable. There is no excess concrete at the flared end, so concrete removal is unnecessary after the structural column is formed, saving concrete materials, time, and labor, and offering good practicality.
