Background

China is a world with a large land and a long history, and the building art source of China is far and long. The architectural artistic styles and the like of different regions are different, but the traditional buildings have common characteristics in the aspects of group layout, space, structure, building materials and the like, and are reputable to the world. Ancient traditional buildings distributed in China are of various types, mainly including palace, temple, tower, folk house and the like. Most of the traditional buildings are mainly brick-laid structures, but the traditional brick-laid structures are also subjected to typical deterioration phenomena of long-term overhaul because of long time.

Through the research on the physical space status of various traditional brick structures, a plurality of places which are not suitable for modern life are found. The traditional brick building is mostly built in the period from the Tang generation to the Qing generation, and the brick building has the possibility of suddenly collapsing at any time under the condition of not reinforcing and repairing. Ancient towers, defense walls, heavy piers and heavy masonry walls are key traditional structures which are widely distributed in the history center of China, so careful repair and reinforcement to restore their performance is of great importance for their protection.

Meanwhile, in order to respond to the national call and protect the traditional culture, the important part is to reinforce and repair the traditional masonry structures, so that the cultural value of the traditional masonry structures can be reflected and inherited, in the society with rapidly changing living conditions, the natural historical relics left by ancestors can be kept in intimate contact, and the traditional masonry structures are indispensable factors for the balanced development of human beings; the random, natural and unique and characteristic beautiful and vivid settlement image is protected, and the Chinese aesthetic philosophy of 'harmonious unity' and 'difference' is embodied; meanwhile, the traditional building is also a key interest point which can bring economy, and huge economic benefits can be earned by adopting a mode of tourism and commercial development, so that the preservation and inheritance of the traditional building are emphasized, and the sustainable development of economic value is sought on the basis of ensuring that the ecological balance of the traditional building is not damaged.

In conclusion, how to solve the above problems can reinforce and protect the old traditional brick structure, so that the old traditional brick structure can inhibit the development of cracks in time when bearing the cracks of the long-term compressive load area, provide the crack resistance enough for the structure, and meanwhile, can ensure that the unique traditional brick culture is well inherited, which is a problem to be solved urgently in the traditional stone structure. Therefore, the utility model provides a foundation joint reinforcing structure for improving the crack resistance of the traditional brick-built structure wall.

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As shown in fig. 1 to 3, the present embodiment provides a foundation joint reinforcing structure for improving crack resistance of a traditional brick-laid structure wall, which includes a plurality of vertical reinforcing steel bars 2 arranged on a brick-laid wall 1, wherein the reinforcing steel bars are all in a ring shape around the periphery of the brick-laid wall and embedded into a mortar joint 4. The method is suitable for facing masonry with regular layers, such as brick or stone masonry, but not for broken stone walls and rubble structures which are arranged in a mixed and disorderly manner. In order to increase the friction between the steel bars and the existing mortar, a rough surface should be preferred, and thus when using the steel bars, sand blasting should be performed in advance to treat the contact area. And bending the reinforcing steel bar with the diameter of 6mm into a ring shape, and reinforcing the periphery of the reinforcing steel bar around the brick wall. The mechanical property of the traditional brick masonry structure can be improved after reinforcement, and the reinforcing steel bars horizontally arranged around the wall can reduce the sensitive stress in the brick and the shear expansion amount of the wall, so that the development of cracks can be effectively inhibited, the bending strength of loads inside and outside a plane is improved, and the ductility can be improved to a certain extent. The reinforced traditional brick masonry building can recover the strength and stability.

In the embodiment of the utility model, small holes are drilled between two opposite sides of the same reinforcing steel bar in the brick wall, transverse steel wire ropes 3 are inserted in the small holes, and the end parts of the transverse steel wire ropes are fixedly connected with the corresponding sides of the reinforcing steel bars into a whole.

In the embodiment of the utility model, the reinforcing steel bars are all threaded steel bars with the diameter of 6 mm. Because the mortar joint of the brick wall is small in thickness (usually about 10-15 mm), the steel bar with the diameter of 6mm is preferably selected.

In an embodiment of the utility model, the mortar joint is cut using a suitable tool to a groove height of at least 10mm and a depth of 50-80mm to embed the reinforcing bars and allow the mortar remaining in the masonry to withstand the applied load.

In the embodiment of the utility model, the embedding material layer is made of hydraulic lime, should be accurately compacted so as to have better compatibility with the existing mortar, the depth of the sealing layer is 15-20mm so as to seal the horizontal joint and ensure the appearance and uniformity, and sand or pigment can be used for aesthetic sealing.

In the embodiment of the utility model, three brick masonries are arranged between two adjacent reinforcing steel bars.

In the embodiment of the utility model, the reinforcement process comprises the following steps:

1. and digging and chiseling mortar joints according to every three brickworks, and digging and chiseling grooves with the height of 10mm and the depth of 70 mm.

2. After appropriate grooves are dug, a small hole penetrating the cross section of the wall body is drilled in the groove, and a transverse steel wire rope is inserted into the small hole.

3. And bending the twisted steel bar with the diameter of 6mm into a ring shape, coating adhesive on the surface of the twisted steel bar, embedding the twisted steel bar into the groove around the wall, and connecting the reinforcing steel bars on two sides by using the transverse steel wire rope inserted in the previous step.

4. After the steel bars are placed, filling materials and bonding materials are filled in the grooves to be fixed, and the positions 20mm deep are left in the grooves for sealing.

5. Sealing is performed by using sand or pigment, and the seam is beautifully treated by using a metal brush.

This improve anti theory of operation of basic joint reinforced structure of anti ability of cracking of traditional brick structure wall body does: adopt this kind of improve the crack resistance's of traditional brick masonry structure wall body foundation joint reinforcing structure, can not only make the traditional brick masonry building recovery stability that the old time was repaiied to this reinforcing structure can control its fissured development in more permanent time later, prevents that the crack design from leading to the whole structure to collapse suddenly on the fragment of brick.
