After construction is completed, the thickness of the sandwich of the double-layer rectangular frame is 1-2 cm less than the designed cup wall thickness, so as to facilitate removing this device for subsequent construction. The flower basket bolt tighteners 2 are respectively arranged inside the side walls of the enclosed rectangular frame. Adopting this structure can improve the safety and reliability of the rectangular frame structure, provide a reliable and accurately positioned support model for the forming of the cup-shaped opening, and avoid its deformation.

[0035] The used flower basket bolt tightener 2 can be a commercially available product. Specifically, it includes: a sleeve 211, a connecting rod 212, and an adjusting bolt; the two ends of the sleeve 211 are respectively inserted into the extended ends of the connecting rod 212; through grooves are respectively arranged on the sleeve 211 and the connecting rod 212; the other ends of the connecting rod 212 are respectively connected to the first-layer rectangular frame 11 or the second-layer rectangular frame 12; the adjusting bolt is inserted into the through groove, and after adjusting the depth of the connecting rod 212 inserted into the sleeve 211 according to the adjustment needs, it is fixed by bolts to achieve abutment.

[0036] Specifically, the double-layer rectangular frame can be formed by multiple positioning angle steels 1 and multiple connecting angle steels 3; the side length of the double-layer rectangular frame is adjustable.

Using this device can ensure the squareness of the cup mouth of the cup-shaped foundation. When the construction progress requirement is high, a cup-shaped foundation cup mouth with better squareness can be obtained, meeting both the design requirements and the construction progress requirements, which is beneficial to improving the quality of the cup-shaped foundation cup mouth.

[0046] In a specific embodiment, positioning hooks 4 are respectively installed on the outer side walls of the positioning angle steels 1, and the connecting angle steels 3 are arranged at the corners of the positioning angle steels 1 and connected through a bolt assembly 5.

[0047] In a specific embodiment, positioning angle steels 1 are respectively arranged in the middle areas of the inner side walls of the rectangular frame, with a total of 4 positioning angle steels 1; the positioning angle steels 1 on adjacent side edges are arranged at intervals, and the connecting angle steels 3 are arranged at the top corners of the rectangular holes, and the two side edges of the connecting angle steels 3 are respectively connected to the positioning angle steels 1 on adjacent side edges.

[0050] In a specific embodiment, the two positioning angle steels 1 in the vertical directions are connected and reinforced by the connecting angle steel 3 and the connecting bolt assembly 5, which is a detachable connection to ensure accurate dimensions and squareness.

[0051] When installing the device, the thickness and squareness of the cup wall template are adjusted by adjusting the tightness of the turnbuckle 2. The adjustment stops when the positioning angle steels 1 on both the inner and outer sides of the device are closely attached to the template and meet the wall thickness requirements of the cup mouth foundation structure. At this time, the construction can ensure that the dimensions of the upper part of the cup mouth structure meet the design requirements with small errors.

[0052] When demolishing the device, the dimensions between the positioning angle steels 1 on the inner and outer sidewalls of the rectangular frame are adjusted by adjusting the tightness of the turnbuckle 2.
