Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated structural buildings, and more specifically, to a dry-type splicing node intelligent monitoring interface pad. Background Art

[0002] Since the 21st century, scientific and technological progress and social development have greatly promoted the progress of civil engineering technology, especially the prefabricated structural construction technology has achieved remarkable development. Compared with the traditional cast-in-place construction technology, the prefabricated structural construction technology has gradually been widely promoted and applied due to its unique advantages, such as short construction period, controllable component quality, low resource consumption, high energy efficiency and environmental sustainability.

[0003] Among the current relevant technologies, when constructing prefabricated components of prefabricated buildings, a complete set of advanced technologies such as positioning, adjustment, and automatic welding will be used for the splicing of two components to ensure the precision of the splicing as much as possible. At the same time, in order to ensure the waterproof performance of the building, it is mainly started from the two aspects of design and construction; in terms of design, a combination of material waterproofing and structural waterproofing is adopted in the joints of prefabricated components and door and window openings and other weak waterproof parts, and suitable sealants are selected to do a good job of external waterproofing, or water pipes and cavities are set in the joints. When clear water appears in the joints, it can be discharged through the water pipes and cavities. In terms of construction, attention is paid to improving the construction process level during construction, such as the sealant embedding process and the burial of water pipes.

[0004] With regard to the current related technologies, the inventors have found the following shortcomings: although these methods can achieve accurate splicing and waterproofing to a certain extent, during the building splicing and operation stages, the splicing interface may suffer certain damage or in the event of sudden unknown and uncertain risks, it is difficult to discover and predict, thereby affecting the bearing capacity of the entire prefabricated building structure system, resulting in problems with the safety and normal usability of the structure; at the same time, when public structural buildings are in a relatively harsh environment and water seepage occurs, it is necessary to timely analyze the water quality and explore whether it is corrosive. By analyzing the length of water seepage time and the amount of water, it is necessary to determine whether it has an adverse effect on the building splicing nodes, so that corresponding emergency measures can be taken in time to ensure the safety of public buildings.

[0005] Therefore, the present invention aims to design and provide a dry splicing node intelligent monitoring interface pad to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a dry-type splicing node intelligent monitoring interface pad, which is used between the splicing positions of two prefabricated components. It can monitor the stress and water seepage conditions of the contact interface in real time, and analyze the water quality components, so as to provide data support for possible risks and formulate targeted emergency measures. The use of this interface pad will significantly improve the safety and stability of prefabricated buildings, while improving the efficiency and effectiveness of building maintenance.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A dry-type splicing node intelligent monitoring interface pad, comprising a pad body, the pad body is provided with at least one hole penetrating through its opposite side walls, the hole is provided with an analysis sensor, and the analysis sensor is adapted to the size of the hole;

[0015] S2. Customize a silicone mold with corresponding size and holes according to the length, width and thickness parameters of the interface pad;

[0017] S4. Pour the high-definition crystal epoxy resin two-component potting glue into the silicone mold at a uniform speed until the height of the colloid is roughly level with the side wall of the silicone mold, and let it stand for 24 hours to completely solidify;
