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:
The invention belongs to the reinforcing technique field of traditional stone-made house, be specifically related to a kind of traditional stone-made house angle hoop drawknot hardened system and construction technology thereof.
background technology:
Tradition barnacle agriculture room refers to that the body of wall of being built by laying bricks or stones by stone material is as the agriculture room of main supporting member, region significant difference, with a long history, each department stone material kind is different with masonry way, having formed colourful barnacle characteristic, is main one of form that represents of China's traditional residence.Because it has, be easy to gather materials on the spot, the advantage such as various informative, structure long service life, agree with mutually with the culture of agriculture root, self-centered ideology and life style that China is traditional, in China's traditional residence, application is very extensive at present.Tradition barnacle agriculture room, with its unique architectural culture art and in the extensive use of villages and small towns building field, has higher conservation value.
But because the in-service time is long, be subject to the impact of extraneous natural conditions, the construction that adds agriculture room is foundation mainly with the experience of local craftsman's accumulation greatly, randomness is larger, there is potential safety hazard in structure, cause existing barnacle agriculture room occurring multiple quality disease in normal use procedure, wherein longitudinal cross wall junction, corner, barnacle agriculture room cracking be the most obviously, the most general quality problems.The formation in longitudinal cross wall crack, corner, barnacle agriculture room has not only destroyed the attractive in appearance of building integral, had a strong impact on the comfortable for living in agriculture room, and directly reduced the supporting capacity of body of wall, affect the safety of structure, if wall body slit is not controlled, finally can cause body of wall to destroy, agriculture room caves in, and consequence is hardly imaginable.According to investigation on the spot, a large amount of longitudinal cross wall crack, corner, in-service barnacle agriculture room ubiquities, and lack at present control measures effective, economical rationality.
The deadweight of tradition barnacle agriculture room is larger, and agriculture room is affected obviously by Gravitative Loads, and longitudinal cross wall junction, corner, agriculture room shear stress is larger; Meanwhile, be subject to size effect of irregular during barnacle wall construction, sting raft, overlap joint inconvenience between stone, a little less than causing connecting between longitudinal cross wall, above-mentioned reason all causes traditional barnacle agriculture room to suffer corner longitudinal cross wall crack disease situation serious.According to investigation on the spot, Distribution Area, the traditional barnacle agriculture room level of economic development is limited, and construction technology level is low, how to design construction simple, and effective, the hardened system that economy is strong is the key issue of corner stirrup drawknot hardened system design and construction.
