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 scope of protection of the present utility model. Specific Implementation Example 1:
[0030] Please see Figure 1-8As shown, this utility model is a formwork for casting building columns, including a rectangular formwork 1, connecting pins 2, and a movable pressure plate 3. Two adjacent rectangular formworks 1 are fixed together by a row of connecting pins 2, and are arranged vertically between adjacent rectangular formworks 1. Two rows of vertically arranged single-headed threaded columns 13 are fixed to the outer side of the upper half of the rectangular formwork 1. The movable pressure plate 3 is vertically slidably installed on the two rows of single-headed threaded columns 13.
[0031] The rectangular template 1 includes a rectangular plate 11. In order to reduce the overall weight of the rectangular template 1 and to ensure the guiding connection with the movable pressure plate 3, a rectangular channel 12 is provided in the middle of the outer side of the rectangular plate 11 to cooperate with the vertical guidance of the movable pressure plate 3.
[0032] Two rows of single-threaded posts 13 are fixed to the upper end of the rectangular channel 12. The movable pressure plate 3 includes a rectangular pressure plate 31 that slides along the rectangular channel 12. The rectangular pressure plate 31 has elongated circular holes 32 that mate with the two rows of single-threaded posts 13. Nuts 4 are threaded onto the single-threaded posts 13 for tightening and fixing the movable pressure plate 3. When it is necessary to move the movable pressure plate 3, the clamping of the two rows of nuts 4 is loosened; after adjusting the movable pressure plate 3, the two rows of nuts 4 are tightened again.
[0033] To facilitate the up-and-down movement and adjustment of the movable pressure plate 3, two handles 33 are fixed on the outer side of the rectangular pressure plate 31.
[0034] The two vertical edges on the inner side of the rectangular plate 11 are each chamfered at 45° 14. The chamfered edges 14 on the side of the rectangular template 1 are conducive to sealing the joints of the rectangular template 1 and preventing mortar leakage.
[0035] A row of triangular prism slots 15 is formed on the two vertical edges of the inner side of the rectangular plate 11, and the inner wall of the triangular prism slots 15 is perpendicular to the chamfered portion 14. A rectangular pin slot 16 is formed on the lower end face of the triangular prism slot 15 to engage with the connecting pin 2, and the rectangular pin slot 16 is connected to the chamfered portion 14. In order to ensure the structural strength of the rectangular plate 11, several horizontally arranged reinforcing ribs 17 are fixed in the middle and lower half of the rectangular channel 12.
[0036] The rectangular plate 11 has a rectangular slot 18 on the upper inner side wall for installing wooden templates 5, and the rectangular slot 18 is connected to the rectangular channel 12. Before installing the wooden templates 5, 45° butt joint slopes are made on both sides of the wooden templates 5. The four wooden templates 5 are connected to form a rectangular cylinder. The four wooden templates 5 are installed in the four rectangular slots 18 at the upper end of the four rectangular plates 11. The inner wall of the wooden template 5 is flush with the inner side of the rectangular plate 11, and the outer side of the wooden template 5 is in contact with the movable pressure plate 3. The movable pressure plate 3 provides stable support for the wooden template 5 from the outside, ensuring the relative stability between the wooden template 5 and the rectangular plate 11 when the column is poured.
[0037] The connecting pin 2 includes a plate 21 that engages with the rectangular pin slot 16. A rectangular top plate 22 is fixed to the top surface of the plate 21. After the four rectangular templates 1 are aligned side by side, four rows of connecting pins 2 are inserted to connect the four rectangular templates 1 into a stable rectangular column outer formwork frame, making template connection and installation quick and convenient. For parts with insufficient height, the distance from the top rectangular slot 18 of the rectangular plate 11 to the top is measured, and wooden templates 5 of corresponding height are cut, chamfered, and then inserted into the top rectangular slot 18 of the rectangular plate 11. The clamping of the movable pressure plate 3 by the two rows of nuts 4 is loosened, and the movable pressure plate 3 is moved upward to support the outer side of the wooden template 5. After adjusting the movable pressure plate 3, the two rows of nuts 4 are tightened again. The movable pressure plate 3 provides structural reinforcement for the wooden template 5 filling the upper gap, ensuring that the column template can be adjusted within a certain range on the construction site and meeting the requirements for template sealing.
