As shown in fig. 1 to 2, the reinforcing structure of the present embodiment includes a masonry 1 and a reinforcing layer coated outside the masonry 1, the reinforcing layer is provided with a plurality of sub-reinforcing layers, and each of the sub-reinforcing layers is made of different materials, so that the mechanical structural performance of the masonry 1 is improved from a plurality of angles, thereby realizing reinforcement of the masonry 1. Hereinafter, a specific structure of the above-described member of the reinforcing structure according to the present utility model will be described in detail.

It should be noted that, the masonry 1 in this embodiment is the most common brick column in the present building structure, that is, the masonry 1 is formed into a rectangular columnar structure and is built by bricks, but in practical application, the shape, size, kind of the used bricks, and the like of the masonry 1 are not particularly limited, that is, the application range of the reinforcement layer described below is not particularly limited.

In addition, it should be further noted that, in order to make the present reinforcing structure achieve a better reinforcing effect, the masonry 1 needs to be subjected to a pre-treatment before the below-described reinforcing layer is provided outside the masonry 1. For example, before reinforcement, the masonry 1 needs to be leveled, and cement mortar with the ratio of 1:3 can be adopted in the working procedure to form a cement layer with the thickness of 10mm on the top of the masonry 1, so that the flatness of the masonry 1 is ensured; for another example, in order to reduce stress concentration at the corners of the masonry 1 (i.e., at the four edges of the rectangular parallelepiped-shaped columns in the present embodiment), chamfers having a radius of 20mm are formed at the corners of the masonry 1; in addition, in order to ensure the tightness of the bonding between the below-described reinforcing layer and the masonry, thereby better performing the reinforcing function, loose substances on the surface of the masonry 1 need to be brushed away by steel wires.

In this embodiment, as shown in fig. 1 to 2, the reinforcing layer includes a first sub-reinforcing layer 21, a second sub-reinforcing layer 22 and a third sub-reinforcing layer 23 which are sequentially bonded, and the first sub-reinforcing layer 21 is located at a side close to the masonry 1. Specifically, the first sub-reinforcing layer 21 is formed as an ECC face layer (i.e., the first sub-reinforcing layer 21 is made of an engineering cement-based composite material) which is coated on the side surface of the masonry 1, and the coating thickness of the first sub-reinforcing layer 21 is 15mm. Due to the characteristics of the engineering cement-based composite material, such as its better ductility, etc., it is possible to improve the integrity of the masonry 1 and to provide the masonry 1 with a good co-operating ability with the first sub-reinforcement layer 21 after being applied to the surface of the masonry 1. In addition, the first sub-reinforcing layer 21 can generate a stronger hoop effect on the brick column, so that the masonry 1 is in a three-way compression state, and the bearing capacity and the deformability of the masonry 1 are improved.

The proportions of the engineering cement-based composite material used for the first sub-reinforcing layer 21 are not fixed, so long as the above technical effects can be achieved. In addition, in order to avoid the first sub-reinforcing layer 21 from generating larger cracks prematurely under the lateral deformation, the tensile strength of the ECC facing layer should be greater than 6MPa, and at the same time, the ultimate elongation of the engineering cement-based composite should be greater than 5%, and it is also necessary to ensure that the engineering cement-based composite has better fluidity so as to facilitate smoothness in the coating construction of the first sub-reinforcing layer 21.

If the above-mentioned first sub-reinforcing layer 21 is used singly to reinforce the masonry 1, the first sub-reinforcing layer 21 located in the corner area of the masonry 1 may fall off, and therefore, in this embodiment, the second sub-reinforcing layer 22 is further disposed on the outer side of the first sub-reinforcing layer 21 facing away from the masonry 1.

Specifically, as shown in fig. 1 to 2, the second sub-reinforcement layer 22 in the present embodiment includes four reinforcement members 220, each reinforcement member 220 is disposed at an edge of the cuboid-shaped masonry 1 (i.e., a corner of the masonry 1), and each reinforcement member 220 is bonded to the first sub-reinforcement layer 21, so as to perform composite reinforcement on the first sub-reinforcement layer 21 and the masonry 1, and the reinforcement members 220 can further improve the bearing capacity of the masonry 1. More specifically, the reinforcement 220 is formed with a first reinforcement portion 221 and a second reinforcement portion 222, and the connection of the first reinforcement portion 221 and the second reinforcement portion 222 is formed with an angle so that the first reinforcement portion 221 and the second reinforcement portion 222 can be bonded to the first sub-reinforcement layer 21. The angle of the reinforcement 220 corresponds to the edge of the masonry 1, and since the edge of the masonry 1 is formed with a chamfer, and the first sub-reinforcement 21 is attached to the masonry 1, the side of the angle between the first reinforcement 221 and the second reinforcement 222 facing the masonry 1 is also formed with a chamfer.

The thickness, the size (the size of the first reinforcing portion 221 and the second reinforcing portion 222) and the like of the reinforcing member 220 are not particularly limited as long as the above technical effects can be achieved. It should be ensured that the length of the reinforcement 220 is the same as the height of the masonry 1, so that a complete reinforcement of the masonry 1 can be achieved. In addition, the plurality of reinforcing members 220 and the first sub-reinforcing layer 21 are bonded by the epoxy resin, so that the structure and function of the first sub-reinforcing layer 21 can be not damaged while ensuring the firmness and tightness of the connection of the reinforcing members 220 and the first sub-reinforcing layer 21. Preferably, the reinforcement 220 is formed as angle steel, and in order to avoid rusting or the like of the reinforcement 220, cement is further coated on the side of the reinforcement 220 facing away from the masonry 1.

In this way, under the action of the reinforcement 220, not only the longitudinal bearing capacity of the masonry 1 is improved, but also the lateral deformation of the masonry 1 after the crushing of the bearing columns can be effectively restricted, so as to avoid the risk of failure or even collapse of the masonry 1 after the crushing of the bearing columns of the masonry 1.

In addition, the first sub-reinforcing layer 21 and the second sub-reinforcing layer 22 in this embodiment are respectively configured as an engineering cement-based composite material and angle steel, and the two layers of the engineering cement-based composite material and the angle steel are used for carrying out composite reinforcement on the masonry 1, so that the material properties of the two layers of the engineering cement-based composite material and the angle steel can be greatly exerted, the defect that the strength of the masonry 1 reinforced by the engineering cement-based composite material is insufficient, the problem that the angle steel is easy to yield in advance due to the transverse deformation effect of the masonry 1 is overcome, and the two layers of the engineering cement-based composite material and the angle steel can provide an extremely strong circumferential constraint force for the masonry 1.

Further, the second sub-reinforcement layer 22 is provided with a third sub-reinforcement layer 23 on the side facing away from the masonry 1. The third sub-reinforcing layer 23 includes a plurality of reinforcing plates 230, both ends of the reinforcing plates 230 in the length direction are respectively connected to the adjacent two reinforcing members 220, and the plurality of reinforcing plates 230 located at the same side of the masonry 1 are arranged in the height direction of the masonry 1. In addition, concrete is poured between the reinforcement plate 230 and the hollow portion 231 of the first sub-reinforcement layer 21 to ensure the overall stability of the present reinforcement structure.

It should be noted that the size, length, etc. of the reinforcement plate 230 are not particularly limited as long as it can connect the adjacent two reinforcement members 220 to improve the stability of the overall structure. Preferably, in this embodiment, the reinforcement plate 230 is provided only at the position of the side of the masonry 1 near the bottom edge and at the center of the side of the masonry 1, so as to facilitate the subsequent maintenance or further reinforcement. Also, the reinforcement plate 230 is preferably formed as a gusset plate.

According to the reinforcement structure of the present utility model as described above, reinforcement of the masonry 1 can be achieved by cladding the reinforcement layer on the outside of the masonry 1. The reinforcing layer comprises a plurality of layers of sub-reinforcing layers which are sequentially arranged outside the masonry 1, and each layer of sub-reinforcing layer is made of different materials, so that the limitation of a single material can be broken through by the composite reinforcing layer of multiple materials, and the ductility, the bearing capacity and the like of the masonry 1 are enhanced.

Finally, it should be noted that: the foregoing examples are merely specific embodiments of the present application, and are not intended to limit the scope of the present application, but the present application is not limited thereto, and those skilled in the art will appreciate that while the foregoing examples are described in detail, the present application is not limited thereto. Any person skilled in the art may modify or easily conceive of the technical solution described in the foregoing embodiments, or make equivalent substitutions for some of the technical features within the technical scope of the disclosure of the present application; such modifications, changes or substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and are intended to be included in the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
