Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a formwork-free structural column superimposed building block. Background Art

[0002] Structural columns refer to reinforced concrete structural columns that should be installed in the walls of multi-story brick-concrete structures in order to enhance the integrity and stability of the building. They should be connected to the ring beams of each floor to form a spatial frame that can resist bending and shearing. It is an effective measure to prevent the collapse of houses. A formwork-free structural column composite block is required during the construction of the structural columns.

[0003] In the Chinese patent with publication number CN204898942U, a formwork-free structural column is mentioned. The structural column is arranged between two adjacent walls. The sides of the two adjacent walls are connected by formwork blocks. The formwork blocks are layered along the height direction of the structural column. A steel cage is arranged in the columnar cavity surrounded by the formwork blocks and the wall. The steel cage and the wall are tied and fixed by a tie piece. Concrete is poured in the columnar cavity. The formwork blocks and the wall blocks on both sides are constructed at the same time. The utility model replaces the traditional formwork with formwork blocks, eliminating the formwork and demoulding processes; and the formwork blocks can be firmly combined with the concrete of the structural column to form a whole and bear force together.

[0004] However, the above-mentioned device utilizes the formwork-free method to save construction costs, and replaces the traditional formwork with formwork blocks, eliminating the formwork and demolding processes. Although no formwork is used, wooden squares and tension bolts are used for reinforcement, and the traditional structural column construction method is not completely replaced. The material cost and labor cost are increased accordingly. The formwork blocks and wall blocks are cast in layers, which affects the integrity of the cast-in-place structural columns and is prone to forming cold joints. The practicality and cost in actual operation are ignored.

[0005] To this end, those skilled in the art have proposed a formwork-free structural column composite building block to solve the above-mentioned problems. Utility Model Content
