Embodiment 1

[0055] Embodiment 1: as Figure 1 to Figure 7 A cantilever frame support structure protruding from the outside of the building is shown, including the upper side beam 1 of the stairs, the middle side beam 2 of the stairs, the lower side beam 3 of the stairs and the internal wall 4 of the building, and also includes the horizontal I-beam 5 and the oblique I-beam 6. A plurality of horizontal I-beams 5 are arranged side by side along the length direction of the upper side beam 1 of the stairs and on the upper side beam 1 of the stairs and the inner wall 4 of the building. The front end of each horizontal I-beam 5 is connected to the Slanted I-beams 6 are arranged between side beams 2 in the staircase; along the length direction of the upper side beams 1 of the stairs and at the front end of the top of the horizontal I-beams 5, I-beam groups A51 and I-beams are welded side by side. Group B52, the top of the I-shaped steel group A51 is welded with a maintenance scaffold 53, and the...

Embodiment 2

[0075] Embodiment 2: the height of the maintenance scaffold 53 mentioned in the present invention is higher than the height 2m of the cantilevered frame mold 59, which helps the construction personnel to work safely. Wherein, the I-beams and steel pipes involved only use the commonly used No. 16 I-beam, steel pipe and other conventional materials can complete the construction of the cantilever frame, which saves costs and facilitates construction.

Embodiment 3

[0076] Embodiment 3: In order to ensure the construction safety of the main body of the building, an exterior wall scaffold 70 needs to be erected against the building exterior. The inner side of the exterior wall scaffold 70 is 0.3m away from the wall, and the width of the exterior wall scaffold 70 is 1m. In addition, the maintenance scaffold 53 The horizontal steel pipes M56 on the left and right sides are fixed together with the external wall scaffolding 70 on the left and right sides, which can form a safe, effective and complete suspension beam frame system, thereby ensuring the safety of construction personnel during the construction of the external maintenance scaffolding 70 .

Abstract

The invention discloses a cantilever framework supporting structure protruding out of the outer side of a building. The cantilever framework supporting structure comprises a stair upper edge beam, a stair middle edge beam, a stair lower edge beam, a building internal wall, horizontal I-shaped steel and oblique I-shaped steel. The horizontal I-shaped steel is arranged in the length direction of thestair upper edge beam and located on the stair upper edge beam and the building internal wall in parallel, and the oblique I-shaped steel is arranged between the front tip of the horizontal I-shapedsteel and the stair middle edge beam. I-shaped steel sets A and B are welded to the front end of the top of the horizontal I-shaped steel in parallel in the length direction of the stair upper edge beam, a maintenance scaffold is welded to the top of the I-shaped steel set A, and a supporting bent frame is welded to the top of the I-shaped steel set B. According to the structure, the maintenance scaffold is erected on the outer side of a cantilever framework, and the safety of the cantilever framework during construction can be effectively guaranteed; meanwhile, the outer side maintenance scaffold and a building body outer wall scaffold are connected and fixed on the two sides, an organic whole body can be formed by a whole safety maintenance system, and the safety of the outer side maintenance scaffold is guaranteed.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a cantilever frame support structure protruding from the outside of a building and a construction method thereof. Background technique [0002] In order to highlight the external modeling effect of modern buildings, concrete frames are often set up on the high altitude of the building to highlight the building's exterior walls, and are used to install decorative components such as stone, aluminum plates, glass, logos, etc., thereby increasing the layering of the building's facade and reflecting the architectural designer. architectural intent. [0003] Because the concrete frame protrudes from the facade of the building, it has caused great difficulties to the construction. At this time, cantilevered supports are often installed on the lower layer of the cantilevered frame. And high-altitude operations are extremely dangerous, and even improper operation by construction p...
