[0001] This patent relates to the technical field of casting forms, and specifically to a special-shaped column casting form that is convenient for assembly. Background Technique

[0002] With the development of society, people's pursuit of aesthetics has been increasing continuously. The increase in architectural diversity has given rise to various special-shaped columns for decorative or structural stress requirements. At the same time, it is also a requirement of building construction. Special-shaped columns have a specific load-bearing role in actual construction and cannot be easily cancelled. Therefore, in the cast-in-place construction method, the establishment of the formwork support system for them is a significant test.

[0003] Traditional reinforced concrete wall columns are mostly fixed by tie bolts or steel pipe systems, which have good effects for regular-shaped columns, with stable structures and few phenomena such as formwork bulging. However, for special-shaped columns, these fixing methods have certain limitations, and the formwork cannot be stressed stably, resulting in a poor final forming effect. Therefore, a special-shaped column casting form that is convenient for assembly is needed to solve this problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0022] See also Figures 1-4 This patent provides a technical solution: a special-shaped column casting template that is easy to assemble, including an inner vertical template 1, a cross-section template 2 and an outer vertical keel 3, the cross-section template 2 is evenly installed on the outer side of the inner vertical template 1, and the side wall of the cross-section template 2 is provided with a clearance groove 4, and the outer vertical keel 3 is inserted and installed in the clearance groove 4;

[0023] By arranging a plurality of cross-section templates 2 outside the inner vertical template 1, the original irregular outer wall of the template is changed into a column of regular shape, so as to facilitate connection and fixation with the external steel pipe system, greatly reducing the occurrence of mold expansion, and the arrangement of the plurality of cross-section templates 2 and the outer vertical keel 3 can also improve the structural strength of the device and the pressure bearing capacity of the casting template;

[0024] A connecting screw 5 is installed on the left lower wall of the cross-section template 2, and a groove 6 is opened on the right lower wall of the cross-section template 2. A threaded cylinder 7 is rotatably installed in the groove 6. The connecting screw 5 can be screwed into the threaded cylinder 7. A first bevel gear 8 is installed on the outer side of the threaded cylinder 7. A rotating sleeve 9 is rotatably installed on the side wall of the cross-section template 2. The rotating sleeve 9 penetrates the side wall of the groove 6 and is installed with a second bevel gear 10. The first bevel gear 8 is meshed and connected with the second bevel gear 10.

[0025] A square hole 11 is formed at one end of the rotating sleeve 9 located outside the cross-section template 2;

[0026] When splicing the device, two devices need to be spliced ​​in reverse, with the end of one corresponding to the tail of the other, so that the connecting screw 5 on one cross-section template 2 can correspond to the threaded tube 7 on the other cross-section template 2, and then the threaded tube 7 is rotated to splice the two devices together to form a complete special-shaped column casting template;

[0027] In order to facilitate the rotation of the threaded barrel 7, a rotating sleeve 9 is provided on the side wall of the cross-sectional template 2 of this device. Through the cooperation of the second bevel gear 10 on the rotating sleeve 9 and the first bevel gear 8, the threaded barrel 7 can be rotated very easily. And this structure is located inside the cross-sectional template 2, so it will not come into contact with external rainwater, etc., avoiding rust and affecting the later disassembly of this device.

[0028] Specifically, one end of a connecting plate 12 is hinged to the side wall of the cross-sectional template 2. The other end of the connecting plate 12 is inserted and installed with a positioning pin 13. The cross-section of the positioning pin 13 is square, and the positioning pin 13 can be inserted and installed in a square hole 11.

[0029] By setting the positioning pin 13, after the splicing of this device is completed, by inserting the positioning pin 13 into the square hole 11, it can prevent the rotating sleeve 9 from rotating, avoiding loosening at the splicing part of this device and affecting the splicing stability of this device.

[0030] Specifically, the cross-section of the inner vertical template 1 is arc-shaped, and the arc of the inner vertical template 1 is consistent with the arc of the external special-shaped column. The inner side wall of the cross-sectional template 2 is closely attached to the side wall of the inner vertical template 1, and the outside of the cross-sectional template 2 is square.

[0031] By setting the outside of the cross-sectional template 2 to be square, it can facilitate the connection of this device with the external steel pipe fixing system, increase the contact area with the external steel pipe system, and thus improve the fixing effect and structural stability degree of this device.

[0032] Specifically, a positioning block 14 is installed on the side wall of the outer vertical keel 3. A placement groove 15 is opened on the side wall of the positioning block 14. The cross-section of the placement groove 15 is semi-circular, and an external positioning steel pipe can be clamped and installed in the placement groove 15.

[0033] Through the cooperation between the placement groove 15 on the side wall of the positioning block 14 and the external steel pipe, the stress area of this device can be increased, and thus the stability degree of this device after being connected to the external steel pipe system can be further improved.

[0034] Specifically, a connection groove 16 is opened on the side wall of the outer vertical keel 3. A slider 17 is installed on the side wall of the positioning block 14, and the slider 17 can slide in the connection groove 16.

[0035] The positioning block 14 is installed on the outer vertical keel 3 through the cooperation of the slider 17 and the connection groove 16, so its position can be changed according to the position of the external steel pipe, improving the applicability of this device.

[0036] Specifically, sealing gaskets 18 are fitted and installed at both ends of the inner vertical template 1.

[0037] The setting of the gasket 18 can improve the sealing performance of the device after splicing, and avoid the leakage of materials after the two inner vertical templates 1 are spliced.

[0038] Working principle: When splicing the device, it is necessary to splice the two devices in the reverse direction, with the end of one corresponding to the tail of the other, so that the connecting screw 5 on one cross-sectional template 2 can correspond to the threaded cylinder 7 on the other cross-sectional template 2. Then, the threaded cylinder 7 is rotated by the cooperation of the second bevel gear 10 and the first bevel gear 8 on the rotating sleeve 9, so that the two devices are spliced together to form a complete special-shaped column casting formwork.

[0039] After the assembly is completed, by inserting the positioning pin 13 into the square hole 11, it can prevent the rotating sleeve 9 from rotating and avoid the loosening of the splicing part of the device, affecting the stability of the splicing of the device.

[0040] Then, the staff can adjust the position of the positioning block 14 according to the position of the steel pipe in the external steel pipe system, and insert the steel pipe into the placement groove 15, so as to fix the device through the steel pipe.

[0041] After all the above steps are completed, the staff can pour concrete into the cavity formed by the inner vertical templates 1 to complete the casting of the special-shaped column.
