Description

A transition structure for the inner and outer frames of a layered cantilever structure Technical Field

[0001] This utility model relates to a conversion structure between inner and outer frames with a layered cantilever structure, and particularly to the field of scaffolding. Background Technology

[0002] External scaffolding refers to temporary structures erected outside a building for the entry, exit, and operation of personnel, materials, and equipment; it is an auxiliary facility in construction.

[0003] The internal support frame is composed of rods and accessories connected reliably. It is supported on the ground or structure and can withstand various types of loads, providing reliable support for building construction.

[0004] When a building has a cantilevered structure, the existing scaffolding erected below the cantilevered structure often does not meet the requirements for high formwork support, necessitating its dismantling and reconstruction. If only the formwork support requirements are considered when arranging the uprights, problems may arise such as excessive upright density making it difficult for workers to operate, and insufficient spacing between the uprights and the sides of beams and columns, making it impossible to erect the side formwork for beams and columns. Summary of the Invention

[0005] This utility model provides a conversion structure for the inner and outer frames of a layered cantilever structure to overcome the defect in the prior art where the scaffolding under the cantilever structure needs to be repeatedly dismantled and re-erected to meet construction requirements.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a conversion structure for an inner and outer scaffold of a layer-by-layer cantilever structure, including an outer scaffold connected to a conversion area scaffold, and the conversion area scaffold connected to an inner formwork support frame on the floor. The inner formwork support frame on the floor is divided into an inner formwork support frame before conversion and an inner formwork support frame after conversion. The inner formwork support frame before conversion includes an adjacent inner scaffold area before conversion and an outer scaffold area before conversion, and the inner formwork support frame after conversion includes an adjacent inner scaffold area after conversion and an outer scaffold area after conversion.

[0008] Furthermore, the pre-conversion internal scaffolding area includes the internal support frame on this floor.

[0009] Furthermore, the pre-conversion external scaffolding area includes longitudinally arranged conversion area scaffolding uprights, external scaffolding and wall ties connected to the outermost uprights, as well as transversely arranged horizontal bars that need to be removed.

[0010] Furthermore, the converted internal scaffolding area includes uprights that convert the external scaffolding into a support frame and horizontal bars that connect to the internal support frame on the floor. An upper-level formwork structure is provided above the uprights that convert the external scaffolding into a support frame, and formwork components are connected between the uprights that convert the external scaffolding into a support frame and the upper-level formwork structure.

[0011] Furthermore, the formwork support component is an adjustable support.

[0012] Furthermore, the scaffolding in the transition area, the external scaffolding, and the internal formwork support on each floor are all disc-lock scaffolding.

[0013] The beneficial effects achieved by this utility model are as follows: When the scaffold is converted, the scaffold erected to the bottom of the cantilever structure is converted into a support frame by adding corresponding formwork components. The inner and outer scaffolds are separated from the scaffolds in the unconverted area by removing the crossbars. The position where the crossbars are removed is the dividing position between the inner and outer scaffolds. The outer scaffold is stabilized by wall ties. The scaffold converted into the support frame of the cantilever structure is stabilized by tying it to the existing support frame on the inner side. This achieves efficient conversion between the inner and outer scaffolds of the cantilever structure, which can shorten the construction period, reduce material waste and usage, and save labor costs.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example 1

[0021] As shown in Figures 1-3, a conversion structure for an inner and outer scaffold of a layered outward cantilever structure includes an outer scaffold 2, which is connected to a conversion area scaffold 1. The conversion area scaffold 1 is connected to an inner formwork support 3 on each floor. The inner formwork support 3 on each floor is divided into an inner formwork support before conversion and an inner formwork support after conversion. The inner formwork support before conversion includes an adjacent inner scaffold area 4 and an outer scaffold area 5. The inner formwork support after conversion includes an adjacent inner scaffold area 6 and an outer scaffold area 7.

[0022] Before the conversion, the internal scaffolding area 4 includes the internal support frame 41 on this floor.

[0023] The external scaffolding area 5 before conversion includes longitudinally arranged conversion area scaffolding uprights 51, external scaffolding 52, and wall ties 53 connected to the outermost uprights, as well as transversely arranged horizontal bars 54 that need to be removed.

[0024] The converted internal scaffolding area 6 includes uprights 61 that convert the external scaffolding into a support frame and horizontal bars 62 that connect to the internal support frame on the floor. An upper formwork structure 63 is provided above the uprights 61 that convert the external scaffolding into a support frame. Formwork components 64 are connected between the uprights 61 that convert the external scaffolding into a support frame and the upper formwork structure 63.

[0025] The formwork support component 64 is an adjustable support.

[0026] The scaffolding in the transition area 1, the external scaffolding 2, and the internal formwork support 3 are all disc-lock scaffolding.

[0027] The formwork support component 64 is connected to the internal support frame 41 of this floor through the horizontal bar 62 connected to the internal support frame of the floor. After removing the horizontal bar 54 and wall tie 53 that need to be removed, it is connected to the outermost side of the external scaffold 52 to realize the separation of the internal and external scaffolds and complete the conversion of the scaffold body of this floor. When the remaining part of the external scaffold in the conversion area scaffold 1 is converted into a support frame, this operation is repeated. The final state is that except for the outermost external scaffold 2, all the rest are converted into support frames.

[0028] During the scaffolding conversion, the scaffolding 1 in the conversion area has been transformed from an outer scaffolding to an inner scaffolding. The outer scaffolding 2 does not participate in the conversion. The scaffolding erected to the bottom of the cantilever structure is converted into a support frame by adding corresponding formwork components 64. The inner and outer scaffolding are separated from the outer scaffolding area 5 before conversion by removing the horizontal bars 54. The location of the horizontal bars 54 to be removed is the boundary between the inner and outer scaffolding. The outer scaffolding 2 is stabilized by wall ties 53. After conversion, the outer scaffolding area 7 is stabilized by tying it to the existing inner support frame.
