[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The embodiment of the present application provides a fireproof and heat-insulating material laying process verification structure, which can solve the problem that the testing and verification of fireproof and heat-insulating materials on a single structural member cannot fully simulate the actual working conditions of the ship in a complex environment, resulting in limited universality and comparability of the test results.

[0037] Example 1

[0038] See also Figures 1 to 3 As shown, the embodiment of the present application provides a fireproof and heat-insulating material laying process verification structure, including: an integrated board 1, a simulation component and a balance component, wherein the integrated board 1 has a plane area 10 and a curved area 11, wherein the curvature radius of the curved area 11 is preferably set to 0.65m; the set simulation component includes an opening simulation part 2, a cabin penetration simulation part and a steel simulation part, and the opening simulation part 2, the cabin penetration simulation part and the steel simulation part are distributed on the integrated board 1, and the integrated board 1, the opening simulation part 2, the cabin penetration simulation part and the steel simulation part are all made of steel Q235. After processing, the overall mass of the structural part is about 300kg. When in use, heat insulation materials are laid on the integrated board 1, the opening simulation part 2, the cabin penetration simulation part and the steel simulation part; the last set balance component is connected to the integrated board 1 and is used to support the integrated board 1 to keep the integrated board 1 in a stable state.

[0039] Thus, the present application effectively simulates the installation environment of different parts by processing the integrated board 1 and dividing the integrated board 1 into a flat area 10 and a curved area 11. Then, the opening simulation parts 2, the cabin penetration simulation parts and the steel simulation parts are distributed on the integrated board 1, effectively providing a stable and reliable installation platform, so that the simulation components can be installed according to the predetermined layout, and at the same time, it is convenient to lay the insulation material, so as to realize the simulation of various cabin structures, including but not limited to cabins, engine rooms, pipelines, and cable troughs.

[0040] At that time, the insulation material will be laid on the integrated board 1 and the simulation components, which will effectively unify the test conditions and integrate and compare various structures, different materials and processes of the cabin. This will help to establish a set of industry-recognized test standards and data comparison benchmarks, significantly improve research work efficiency and tooling utilization, promote the continuity and consistency of process research, and provide strong support for the rapid development and application of new materials.

[0041] In addition, since the analog components are integrated and installed on one side, in order to ensure the stability of the structure of the integrated board 1 and normal use, a balancing component is also provided to maintain the stability of the integrated board 1 and a reliable structure.

[0042] In the present application, the opening simulation part 2 includes an air duct opening frame arranged on the curved area 11. The air duct opening frame is used to simulate the scene of the air duct passing through the curved area 11, verify the sealing and fireproof performance of the thermal insulation material at the air duct opening, and ensure that the opening will not become a channel for the spread of fire. The width of the air duct opening frame is preferably 20 cm and the length is preferably 40 cm.

[0043] The set cabin penetration simulation parts include cable cabin penetration pipe fittings 30 and water pipe cabin penetration pipe fittings 31, and the cable cabin penetration pipe fittings 30 and water pipe cabin penetration pipe fittings 31 are both penetrated on the plane area 10. The cable cabin penetration pipe fittings 30 and the water pipe cabin penetration pipe fittings 31 can verify the sealing and fireproof performance of the insulation material around the cabin penetration pipe fittings, and prevent the fire from spreading to other areas through the cabin penetration pipe fittings. The cable cabin penetration pipe fitting 30 is set in a waist shape, and its vertical width is preferably set to 16cm, and the horizontal length is 36cm. The horizontal length includes the horizontal section and the arc radius size of the two sections, wherein the horizontal section length is 20cm, and the arc radius is set to 8cm. The water pipe cabin penetration pipe fitting 31 is set in a circular shape, and its diameter is preferably set to 20cm.

[0044] The steel simulation parts include: L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42, and the L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42 are all connected to the integrated board 1, and are arranged in sequence along the height direction of the integrated board 1, and the L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42 are in contact with the plane area 10 and the curved surface extension. Specifically, the L-shaped steel 40 is arranged at the top of the integrated board 1, and the T-shaped steel 41 and bulb flat steel 42 are arranged in sequence downwards, and the integrated board 1 is divided into two areas from top to bottom by the L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42. In the upper area, the air duct opening frame and the cable through-cabin pipe fittings 30 are arranged, and in the lower area, the pipe through-cabin pipe fittings are arranged.

[0045] The L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42 effectively simulate the arrangement of steel in the real structure and verify the fit and fire resistance of the thermal insulation material around the steel. At the same time, the arrangement of the L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42 can also enhance the overall stability and bearing capacity of the verification structure.

[0046] The verification structure of this application verifies the performance of fireproof and heat-insulating materials by simulating various complex conditions in the real environment, such as air duct openings, cabin pipes, steel layout, etc. In the test, the performance of the heat-insulating materials in terms of fire prevention, heat insulation, and sealing can be effectively evaluated, thereby providing a reliable basis for its application in actual engineering.

[0047] In the present application, the balancing assembly includes a plurality of counterweights 50, which are arranged on the integrated board 1 and away from the side of the simulation assembly. The arrangement of the counterweights 50 balances the forces on both sides of the integrated board 1, ensures that the integrated board 1 can be used normally, avoids the situation where the simulation assembly is concentrated on one side of the integrated board 1, and causes tilting, and ensures reliable use.

[0048] In addition, in order to further improve the stability of the integrated board 1, the balancing assembly also includes a triangular support frame 51, which is connected to both sides of the integrated board 1. Under the action of the triangular support frame 51, the stability of the integrated board 1 is effectively reinforced, and the rollover of the integrated board 1 is reduced.

[0049] The present application also includes a base plate 6, which is connected to the bottom of the multi-channel integrated board 1 and extends away from the simulation component. The setting of the base plate 6 increases the contact area between the integrated board 1 and the ground, thereby improving the stability of the integrated board 1. At that time, the counterweight block 50 can be installed on the base plate 6, and the structure is reliable.

[0050] In addition, in order to facilitate the operation of the integrated board 1 when installing or moving the integrated board 1, a plurality of lifting holes 7 are provided on the top of the integrated board 1 and along its length. The lifting holes 7 can help workers or mechanical equipment to install or move the integrated board 1 and provide a safe and stable grasping point. Lifting equipment such as a crane or a forklift can easily lift the simulation part to the required height to ensure that the simulation part will not be damaged during transportation and installation. The number and arrangement of the lifting holes 7 are designed to ensure the convenience of grasping, balance and safety during the lifting process.

[0051] In the present application, the size of the space occupied by the integrated board 1 is also optimized and tested, so the height of the integrated board 1 is preferably set to 1.5m and the length is 1.3m. The length here mainly refers to the length of the vertical plane of the integrated board 1. If the curved area 11 is unfolded along the length direction, the actual length of the integrated board 1 is 1.5m, including 0.75m of the plane area 10 and the curved area 11, and the structural size is set appropriately.

[0052] The implementation principle of the embodiment of the present application is as follows: Q235 steel is used to make an integrated board 1, and the integrated board 1 includes a plane area 10 and a curved area 11, and then L-shaped steel 40, T-shaped steel 41 and bulb flat steel 42 are welded in sequence along the height direction of the integrated board 1, and a duct opening frame is set on the curved area 11, and a cable through-cabin pipe fitting 30 and a water pipe through-cabin pipe fitting 31 are set on the plane area 10, and finally a counterweight block 50 and a triangular support frame 51 are installed, so as to effectively complete the fireproof and heat-insulating material laying process verification structure, and then the heat-insulating material can be laid thereon. By uniformly arranging a variety of simulated cabin structures, the test conditions can be unified, making it possible to compare different materials and processes. This helps to establish a set of industry-recognized test standards and data comparison benchmarks, significantly improves research work efficiency and tooling utilization, promotes the continuity and consistency of process research, and can provide strong support for the rapid development and application of new materials.

[0053] Example 2

[0054] See also Figures 1 to 3 The embodiment of the present application provides a method for using a verification structure of a fireproof and heat-insulating material laying process, comprising the following steps: laying the fireproof and heat-insulating material on an integrated board 1, an opening simulation part 2, a cabin penetration simulation part and a steel simulation part, ensuring that the material is tightly combined with the simulation part without bubbles or gaps; placing the integrated board 1 laid with the fireproof and heat-insulating material in a test cabin for a high-temperature experiment, and recording the test data of the fireproof and heat-insulating material at various locations on the integrated board 1, the opening simulation part 2, the cabin penetration simulation part and the steel simulation part according to the changes in the experimental temperature and time. These data may include the temperature distribution, thermal conductivity, thermal stability, etc. of the material. According to the evaluation results, necessary adjustments and improvements are made to the laying process of the fireproof and heat-insulating material to improve the performance and laying quality of the material; finally, after the experiment is completed, the integrated board 1 after the experiment is completed is cooled to ensure that the material is in a stable state, and then the laid fireproof and heat-insulating material is removed to prepare for the next experiment.

[0055] In conclusion, the use of the verification structure for the fireproof and heat-insulating material laying process includes three main steps: laying fireproof and heat-insulating materials, conducting high temperature experiments, and cooling and removing fireproof and heat-insulating materials. Through the implementation of these steps, the performance of fireproof and heat-insulating materials in different environments can be comprehensively evaluated, and strong support can be provided for subsequent process improvements.

[0056] In the present application, the removal of the laid fireproof and heat-insulating materials specifically includes: removing glue, removing primer and polishing the integrated board 1. Among them, the glue removal uses an appropriate solvent or tool to remove the adhesive between the fireproof and heat-insulating materials and the integrated board 1. This step helps to ensure the smooth progress of subsequent processing; the primer removal is completed by polishing or wiping with tools such as scrapers and sandpaper. Polishing treatment: polishing the surface of the integrated board 1 to remove the residual fireproof and heat-insulating materials and primers, and restore the flatness of the surface of the integrated board 1. During the polishing process, attention should be paid to controlling the strength and speed to avoid damage to the integrated board 1. The removal of the insulation material is completed, and the operation is convenient, so that the integrated board 1 and the simulation components can be reused, which not only saves the time and cost of new material verification, but also significantly improves the research work efficiency and the utilization rate of tooling.
