Rural masonry structure assembled integral type ring beam-constructional column combination technology

Abstract

The invention discloses a rural masonry structure assembled integral type ring beam-constructional column combination technology. The technology comprises the steps that (1) ring beam blocks, tenon blocks, constructional column blocks not containing horse tooth troughs, constructional column blocks containing horse tooth troughs and constructional column blocks containing mortises are prefabricated; (2) when a wall is built with bricks, the constructional column blocks not containing horse tooth troughs, the constructional column blocks containing the horse tooth troughs and the wall are assembled and built with the bricks in a staggered mode, and assembled type hollow prefabricated construction columns are formed; (3) after masonry, steel reinforcement cages are put into center holes, and assembled integral type constructional columns are formed by concrete pouring; and (4) the constructional column blocks containing the mortises and the prefabricated ring beam blocks are connected, through long ribs with the diameter greater than or equal to 10 mm are distributed in reserved stirrups of the upper portions of the prefabricated ring beam blocks and are connected with the steel reinforcement cages of the constructional columns, clay bricks are laid on the two sides of the upper portions of the prefabricated blocks, concrete is poured, assembled integral type ring beams are formed, and an assembled integral type ring beam-constructional column house is formed through sequential masonry. The rural masonry structure assembled integral type ring beam-constructional column combination technology advantageously achieves industrial production, standard construction and environmental protection of masonry structures, improves the anti-seismic performance of rural masonry structure houses, and ensures the life and property security of people.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a combination of assembly and cast-in-place, which is suitable for assembly integral ring beam-construction column combination technology of masonry structure houses in villages and towns, and meets the "beautiful rural green farm house" vigorously advocated by the state. "Basic requirements for construction. Background technique [0002] Masonry structure is one of the building structure systems with a relatively long history in my country. It has been widely used in various regions for a long time because of its characteristics of easy material acquisition, simple construction, economical and beautiful appearance. From the late 1970s to the early 1990s, masonry structure civil residential buildings once accounted for more than 90% of the total number of residential buildings. Today, masonry structure houses are still the main building structure system us...

Problems solved by technology

[0003] At present, cast-in-place ring beam structural columns are the main anti-seismic fortification measures for masonry structures, and the relevant research results and the seismic damage characteristics of masonry structures in the Wenchuan and Lushan earthquakes have shown the importance of setting ring beams and structural columns. However, in the process of post-disaster reconstruction and villagers' new houses, some villagers are unwilling to use or only partially use ring-beam structural columns, or a small number of ring-beam structural columns are installed, and the construction quality of structural columns and ring beams is very poor and cannot effectively restrain the wall. body, thereby improving the seismic performance of masonry structures

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
