Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a supporting structure of a corner structural column without opening a hole for a template. Background Art

[0002] Structural columns refer to reinforced concrete structural columns that should be set in the walls of multi-story brick-concrete structures in order to enhance the integrity and stability of the building. They are connected to the ring beams of each floor to form a space frame that can resist bending and shearing. It is an effective measure to prevent the collapse of the house. Structural columns are set at the four corners of the exterior wall, the intersection of the horizontal wall and the exterior longitudinal wall at the staggered level, on both sides of the larger opening, and at the intersection of the inner and outer walls of the large room. In addition, the requirements for the setting of structural columns are inconsistent due to the different number of floors and earthquake intensities of the house. The traditional method is to open holes on the surface of the masonry wall on both sides of the structural column. This practice is not environmentally friendly and affects the thermal insulation performance of the wall. The mold expansion phenomenon may occur, which affects the molding quality of the structural column and increases the cost.

[0003] Prior art 202321918580.3 discloses a corner structural column reinforcement device, comprising a positive corner wood square arranged on the outside of the positive corner template, the outer side of the positive corner wood square is provided with an angle-adjustable reinforcement component, the reinforcement component and the negative corner template are connected by a first tension component and a second tension component, the first tension component comprises a first clamp and a first pull rod, the first pull rod is fixedly connected to the lower part of the side of the first clamp, and the other side of the first clamp is provided with a first abutment fastener that passes through the side; the second tension component comprises a second clamp and a second pull rod, the second pull rod is fixedly connected to the side of the second clamp The upper part of the second clamp is provided with a second abutment fastener penetrating the side on the other side; the first clamp and the second clamp are used to fix the reinforcement assembly; the first pull rod and the second pull rod are connected with the fastener after passing through the corresponding structural column tooth joint; although it avoids opening holes in the wall, the structure needs to open holes in the square steel pipe, which cannot adapt to structural columns of various sizes and cannot be recycled. In addition, the width of the steel pipe is limited, and the opening distance between the first steel pipe and the second steel pipe is difficult to control. During on-site use, it was found that it is very easy to pull against each other. The height difference between the two tension bolts on the inner corner side is small, resulting in overlapping of the fastening nuts at the inner corner and inability to tighten.
