Problems solved by technology

Existing column formwork reinforcement systems are usually made of ordinary steel, and for columns with large cross-sectional areas, it is necessary to wear multiple tensioning screws to ensure that the concrete columns will not explode. Low, serious slurry leakage, poor molding quality; the holes formed by the pull bolts have to be filled in the later stage, and the cost increases

Embodiment

[0028] In the specific implementation, the square steel pipe is used to press image 3 Four corner hoops 4 are produced as shown, and a pin hole 7 is processed at both ends of each corner hoope 4. The shape of the pin hole 7 is a long rectangular structure, and the pin hole 7 is a through hole that penetrates up and down. Another example Figure 5 As shown in the figure, four sections of channel steel are taken as the connecting rod 5, and the opening width of the channel steel should be slightly larger than the outer dimension of the square steel pipe used for the angle hoop 4. The length of the connecting rod 5 can be determined according to the size of the large-section concrete column to be poured, and a certain adjustment length is reserved. Then, a group of pin holes 7 are respectively machined at both ends of the connecting rod 5, the pin holes 7 are machined on the two wings of the channel steel, and the distance between the pin holes 7 and the pin holes 7 is 50mm. T...

Abstract

The invention discloses a formwork supporting method and device for a large-section concrete column. A set of connecting rods and a set of corner hoops are connected into rectangular hoops through a set of pin pieces, and a set of formworks are hooped into a rectangular cylinder through the rectangular hoops to serve as a pouring cavity of the large-section concrete column. The device has the scalability, and the size change of the large-section column can be met; and mounting and dismounting are easy and fast, and the beneficial effects of saving labor and time are achieved. Compared with an existing opposite-pull screw reinforcing method, an opposite-pull screw does not need to be arranged, and holes reserved in the opposite-pull screw do not need to be repaired after pouring. The device can be used in a turnover manner, and cost is saved.

Description

technical field [0001] The invention relates to a form-supporting method for a large-section concrete column and a device therefor. It belongs to the technical field of prefabricated building moulds. Background technique [0002] The concrete columns of high-rise buildings or super-high-rise buildings are relatively large in cross-section and vary in size, so there are many problems in the construction process. The existing column formwork reinforcement system is usually made of ordinary steel. For large cross-sectional area columns, multiple pairs of tension screws are required to ensure that the concrete column will not burst. It is relatively low, the slurry leakage is serious, and the forming quality is poor; the holes formed by the pull bolts must be filled later, and the cost will increase. Therefore, there are still deficiencies in the prior art, and further improvement is required. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to prov...
