Angle hoop tie reinforcement system of traditional stone masonry house and construction technology

Abstract

The invention relates to an angle hoop tie reinforcement system of a traditional stone masonry house and a construction technology. The system comprises long steel angles, the long steel angles are used for fixedly clamping outer wall corner angles of the stone masonry house, and one side of each short steel angle is connected with the corresponding long steel angle through diagonal tension plates. A connecting hole is formed in the middle of the other side of each short steel angle. Every two adjacent short steel angles are connected through tie bars penetrating through the connecting holes. The long steel angles, the short steel angles, the diagonal tension plates and the tie bars are mutually connected to form closed steel hoop structures. The steel hoop structures are hooped around the outer wall of the stone masonry house. The tie bars are prestressed steel bars. The steel angles are fixed to the corners of the wall of the stone masonry house, every two adjacent steel angles are connected through the steel tie bars, and prestress is exerted on the steel tie bars, so that the steel tie bars are matched with the steel angles to form the steel hoop structures. The steel hoops generate large constraint force on the corners of the wall, so that the stress condition of the original structure of the stone masonry house is changed, shear stress of connecting positions of longitudinal and transverse walls is reduced, and cracks at the connecting positions of the longitudinal and transverse walls and further expansion of cracks already generated are avoided.

Description

Technical field: [0001] The invention belongs to the technical field of reinforcement of traditional stone houses, and in particular relates to a traditional stone house corner hoop tie reinforcement system and a construction process thereof. Background technique: [0002] Traditional stone masonry farmhouses refer to farmhouses with stone walls as the main load-bearing components. There are significant regional differences and a long history. The types of stone materials and masonry methods in different regions are different, forming colorful stone masonry features. It is one of the main representative forms of traditional dwellings in my country. Due to its advantages such as easy acquisition of local materials, various forms, and long service life of the structure, it is in line with the traditional Chinese farming root culture, self-sufficiency ideology and lifestyle, and is currently widely used in traditional dwellings in my country. Traditional stone farmhouses have...

Problems solved by technology

[0004]The traditional stone-built farmhouse has a large self-weight, and the farmhouse is obviously affected by the self-weight effect, and the shear stress at the joint of the vertical and horizontal walls at the corner of the farmhouse is relatively large; at the same time, the stone-built wall Affected by irregular dimensions during construction, it is inconvenient to bite and overlap between stones, resulting in weak connection between vertical and horizontal walls. The above reasons have caused serious damage to traditional stone-built farm houses from cracks in vertical and horizontal walls at corners

According to field research, the economic development level of traditional stone-built farmhouse distribution areas is limited, and the level of construction technology is low. How to design a simple, effective and economical reinforcement system is the key to the design and construction of the corner steel hoop reinforcement system. question
