Description

Technical Field

[0001] The utility model relates to the technical field of building reinforcement engineering, in particular to a building reinforcement device and a building. Background Art

[0002] Buildings are the general term for buildings and structures. They are artificial environments created by people to meet the needs of social life, using the material and technical means at their disposal and applying certain scientific laws, feng shui concepts and aesthetic principles. Some classifications, in order to clearly express usability, distinguish between buildings and non-building structures that people do not occupy for a long time. In addition, some architectural scholars, in order to avoid confusion, deliberately subdivide the buildings whose exteriors are consciously created by people into "architecture";

[0003] When existing buildings are reinforced, carbon fiber plate composites are usually used. Although carbon fiber plate composites can significantly improve the bearing capacity and durability of buildings, for example, buildings reinforced in this way often lack effective monitoring means for the state of the reinforced buildings; and this lack of monitoring makes it difficult to detect and handle potential safety hazards in a timely manner, thus increasing the risk of building operation. And, in the actual use process, due to the presence of carbon fiber plates, when cracks or fractures occur at the bottom of the building due to environmental or external factors, the staff can only observe them after the carbon fiber plates are damaged. When using the building with cracks or fractures for testing work, the measured data is not accurate.

[0004] Therefore, it is necessary to design a building reinforcement device and a building. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model proposes a building reinforcement device and a building. By embedding fiber Bragg grating sensors during the process of carbon fiber reinforcement of buildings, a structural system capable of real-time monitoring of the building reinforcement state is constructed. This system can not only improve the reinforcement effect of buildings, but also realize continuous monitoring of parameters such as stress and strain of key parts of buildings, providing reliable data support for the safety assessment and maintenance management of buildings to more precisely solve the above problems.

[0006] The utility model is realized through the following technical solutions:

[0007] The utility model proposes a building reinforcement device, which includes at least two carbon fiber plates, and a monitoring component arranged between the two carbon fiber plates. The monitoring component includes an optical fiber, a plurality of strain rosettes connected to the optical fiber, and a receiving member connected to one end of the optical fiber.

[0008] Further, in the present utility model, the strain rosette includes three gratings, and the included angle between the gratings is 45° or 60°.

[0009] Further, in the present utility model, the included angle between the gratings is 45°.

[0010] Further, in the present utility model, adhesives are provided on the inner sides of the two carbon fiber plates, and the optical fiber and the strain rosette are arranged between the two adhesives.

[0011] A building includes a surface body, and a plurality of the building reinforcement devices as described above in any one are provided on the surface body.

[0012] Advantages of the present utility model:

[0013] The reinforcement device integrating a carbon fiber plate and an optical fiber grating sensor can reinforce a building through reasonable arrangement, improving the bearing capacity of the building; the reinforcement device integrating a carbon fiber plate and an optical fiber grating sensor can also monitor the state of the building in real time, timely discover potential safety hazards, and avoid major life and property losses caused by building damage;

[0014] At the same time, the reinforcement device integrating a carbon fiber plate, gratings and optical fibers can also timely discover and handle potential safety hazards, avoiding major repair and replacement costs caused by building damage, and when the force applied to the carbon fiber plate changes greatly, the staff can confirm whether the building is cracked or damaged according to the data change; the existence of the gratings and optical fibers can collect and transmit monitoring data in real time, providing timely and reliable data support for the safety assessment and maintenance management of the building.

[0025] Preferably, reference Figure 1 , adhesives 3 are provided on the inner sides of the two carbon fiber plates 1, and the optical fiber 21 and the strain rosette 22 are disposed between the two adhesives 3; the setting of the adhesives 3 can increase the firmness of the installation of the gratings 221 and the optical fiber 21 on the carbon fiber plate 1, thereby ensuring the stability of the gratings 221 and the optical fiber 21 during use.

[0026] Specifically: First, the staff selects the carbon fiber board 1 according to the building structure. Then, the staff designs the arrangement position of the strain rosette 22 according to the key areas of the surface body 4 to be detected, and marks it with a marker pen. Next, an adhesive 3 is applied to both the carbon fiber board 1, the grating 221, and the optical fiber 21, and the grating 221 and the optical fiber 21 are fixed at the pre-marked positions on the carbon fiber board 1. Among them, the arrangement of the gratings 221 is at a predetermined 45 degrees. Secondly, after the installation, a layer of adhesive 3 is applied to the surfaces of the gratings 221 and the optical fibers 21 to ensure that the gratings and the optical fibers are completely covered. Finally, the adhesive 3 is applied to the inner side of the second carbon fiber board 1, and the second carbon fiber board 1 is glued to the first carbon fiber board 1, so that the gratings 221 and the optical fibers 21 are fixed between the two carbon fiber boards 1. In addition, the staff can use external clamping tools, such as pressing plates or jigs, to clamp the two carbon fiber boards 1, so as to apply a certain pressure to the carbon fiber board 1 until the adhesive 3 cures.

Among them, the position for fixing the carbon fiber board 1 should be pre-cleaned and surface-treated, that is, to ensure that there is no dust, oil stain, and other impurities on the bottom surface of the surface body 4, and to ensure that the bottom surface of the surface body 4 is flat and smooth; after the installation of the carbon fiber board 1, the staff leads out the pins of the optical fiber 21 and the grating 221 and connects them to the receiving component; secondly, the staff applies a certain force to the surface body 4 to ensure that the sensor and the receiving component can work normally; finally, the staff repeats pasting different numbers of carbon fiber boards 1 according to the size of the surface body 4 and the area to be detected, ensuring that the carbon fiber boards 1 cover the entire bottom of the surface body 4;
