Embodiment Construction

[0018] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.

[0019] see figure 1 , a masonry structure to be reinforced has a rectangular plane of about 12m×7m, with three floors in total, the first floor is 3.5m high, and the second and third floors are 3m high. Two horizontal walls are set up, the structure adopts the load-bearing system of the horizontal wall, and the seismic fortification intensity is 7 degrees.

[0020] at the corner of the structure The 90×8 equilateral angle steel is used as the edge vertical steel part 1, and cement mortar is used to bond the edge vertical steel part 1 with the structure to be reinforced; Use -90×8 steel plate as the middle vertical steel part 2, and use cement mortar to bond it with the structure to be reinforced; use - 110×8 steel plate as horizontal steel pa...

Abstract

The invention relates to a method for carrying out earthquake-resistance and strengthening on the traditional masonry structure by using steel parts, comprising the following steps of: using an angle steel as an edge vertical steel part on the corner of the masonry structure to be strengthened; using a steel plate as a middle vertical steel part along a vertical direction on the outer vertical surface of the masonry structure; using a steel plate as a horizontal steel part along a horizontal direction on the outer vertical surface of the masonry structure, wherein the horizontal steel part is connected with the edge vertical steel part adjacent to the horizontal steel part and also connected with the middle vertical steel part overlapped with the horizontal steel part. The invention carries out the earthquake-resistance and the strengthening on the traditional masonry structure by adopting the method, thereby effectively enhancing the integrity of the traditional masonry structure and obviously improving the earthquake-resistant property of the masonry structure.

Description

technical field [0001] The invention relates to a method for anti-seismic reinforcement of existing masonry structures using steel components. Background technique [0002] In the 5.12 Wenchuan Earthquake and the 4.14 Yushu Earthquake, a large number of village and town masonry houses built by the people collapsed, causing great damage to people's lives and properties. Most of this kind of masonry houses have not been properly designed and constructed, and many of them are not even equipped with structural columns and ring beams. There is no effective connection between walls and walls, floors and walls, and the integrity and spatial rigidity of the houses are very poor. There is a big security risk. For example, under the action of strong earthquakes, the joints of vertical and horizontal walls are prone to damage, and the wall collapses in a short period of time, causing the overall structure to lose its bearing capacity. [0003] In order to ensure the safety of life an...
