Construction Method of Embedded Square Concrete Steel Tube Concrete Ring Beam-Construction Column in Masonry Structure

Abstract

The invention discloses a method for constructing a masonry structure embedded square concrete filled steel tube ring beam-constructional column. The method comprises the following steps of: arranging a reinforcement cage on a ground ring beam and sleeving square steel tube on the external of reinforcement cage; constructing a blockwork and packaging and embedding the square steel tube into the blockwork; after completely constructing a first layer of house wall, concreting in the square steel tube and forming a concrete filled steel tube constructional column; and meanwhile, setting node reinforcement cages in different shape according to the practical connecting node of the ring beam-constructional column; inserting the corresponding limbs of the node reinforcement cages into the empty square steel tubes obligated at the top of the bottom layer of concrete filled steel tube constructional column, and meanwhile, inserting the other corresponding limbs of the node reinforcement cages into the same layer of to-be-connected ring beam square steel tube and pouring the concrete and forming the reinforced concrete connecting node; and finally, sleeving a second layer of constructional column square steel tube onto the reinforcement cage obligated on the reinforced concrete node and constructing the blockwork, and repeating the operation, thereby realizing the method for constructing the embedded square concrete filled steel tube ring beam-constructional column.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a construction method of an embedded square steel pipe concrete ring beam-construction column in a masonry structure, which is suitable for ground-floor and multi-layer masonry structures. Background technique [0002] Ring-beam structural columns are the most important earthquake-resistant structural measures in masonry structures. The earthquake damage characteristics of a large number of masonry structures in the "Wenchuan" and "Lushan" earthquakes all show the importance of setting them. In the process of post-disaster reconstruction, due to the advantages of economy, easy access to local materials, short construction period, and simple construction technology, a large number of houses in rural areas and towns still use masonry structures. Setting ring beams in a masonry structure house can enhance the integrity and spatial rigidity of the house, preve...

Problems solved by technology

[0003] Although the relevant research results and the seismic damage characteristics of masonry structures in the Wenchuan and Lushan earthquakes have shown the importance of ring beams and structural columns, some villagers were unwilling to use ring beams or only partially used ring beams in the post-disaster reconstruction process. Structural column

The reasons: firstly, the investment in economic costs increases, and the installation of ring-beam structural columns in masonry structures according to the code requirements will increase the cost by about 25%. Therefore, some villagers with poor family economic conditions give up using structural columns, or only Pouring ring beams, or only setting structural columns on the ground floor, or thickening the thickness of the inner wall plate to replace ring beams, etc.; secondly, the design and pouring of ring beam structural columns is not standardized, which cannot meet the requirements for seismic fortification. Due to the rural economy and Due to limited technical conditions, most of the construction personnel are local craftsmen and relatives in the neighborhood. They lack professional technical knowledge and cannot guarantee the quality, which is not conducive to the safety of the structure. , structural columns are not provided with horse teeth, etc.; moreover, in order to save the construction period and speed up the construction progress, thereby reducing the investment of energy and financial resources, some villagers also voluntarily gave up the use of ring beam structural columns
