Description

Technical Field

[0001] This utility model belongs to the technical field of fireproof coatings for steel structure engineering, specifically relating to a fireproof coating insulation structure for steel structures for winter construction. Background Technology

[0002] Steel structures in buildings include steel columns, beams, and purlins. Fire-retardant coatings are typically applied to the steel columns and beams. However, due to the limitations of the fire-retardant coating material itself, application is impossible below 5°C. To facilitate fire-retardant coating application on steel structures during winter, insulation measures are employed to ensure normal construction. Chinese patent CN113323395A discloses a construction method for applying fire-retardant coatings in winter, specifically: erecting a frame around the steel structure and then fixing insulating cloth to the frame with wire to achieve a sealed insulation effect. Using this structure requires not only erecting the frame but also securing the insulating cloth with wire, making the installation and dismantling of the insulation structure complex. Utility Model Content

[0003] This utility model proposes a thermal insulation structure for winter construction of fireproof coatings on steel structures, which not only achieves thermal insulation of fireproof coatings on steel structures in winter, but also facilitates the fixed installation of the thermal insulation structure.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a steel structure fireproof coating winter construction insulation structure, including several insulation layers with insulation effect and several magnetic adsorptions that can be adsorbed on the steel structure purlins. Each insulation layer is fixed to the steel structure purlins by several magnetic adsorptions, and a connecting structure is provided between adjacent insulation layers.

[0005] As a preferred option among the above solutions, the insulation layer is made of glass wool rolls with a thickness of 3-5cm.

[0006] More preferably, the connection structure includes a magnetic snap-fit ​​built into the edge of each insulation layer.

[0007] Further optimization involves evenly distributing magnetic clasps on each purlin, with a spacing of 1-2m between adjacent magnetic clasps.

[0008] The beneficial effects of this utility model are as follows: By magnetically fixing the insulation layer to the purlin, it not only does not affect the spraying of fireproof coating on the steel columns and beams, but also facilitates the fixing of the insulation layer. At the same time, during disassembly, only the magnetic suction machine needs to be removed, making the disassembly of the insulation layer convenient. Compared with the prior art, this application utilizes the steel structure itself, eliminating the need for scaffolding, which can effectively improve construction efficiency. At the same time, the magnetic force of the magnetic suction is used to fix the insulation layer, thereby facilitating the installation and fixing of the insulation layer. Attached Figure Description

[0009] Figure 1This is a schematic diagram of the present invention. Detailed Implementation

[0010] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0011] like Figure 1 As shown, a fireproof coating insulation structure for steel structures is designed for winter construction and mainly consists of several insulation layers 1 and several magnetic ties 2. The insulation layers are used to insulate the steel structure and are magnetically fixed to the purlins. Connecting structures are provided between adjacent insulation layers.

[0012] Ideally, the insulation layer should be made of glass wool rolls, with a thickness of 3-5 cm. For steel structures with wall purlins, when covering the purlins with insulation, the length of the same roll of insulation should at least cover the adjacent beam purlins and wall purlins, and ideally, the length of the same roll of insulation should cover the beam purlins and the adjacent wall purlins on both sides.

[0013] To ensure overall insulation performance, the connection structure consists of magnetic snap-fits built into the edges of each insulation layer. This allows the edges of adjacent insulation layers to fit tightly together, preventing gaps between them. Ideally, the edges of the fitted insulation layers should not be close to the purlins, and the edges of the non-fitted insulation layers should adhere to the steel structure, effectively preventing gaps at the edges of the insulation layers and thus ensuring overall insulation performance.

[0014] The magnetic attraction can be made of magnetic strips or magnetic blocks. The magnetic force of the magnetic attraction must be sufficient to fix the insulation layer to the purlin. When the magnetic force of the magnetic attraction is insufficient, a stronger magnetic attraction can be replaced or the number of magnetic attractions can be increased to ensure that the insulation layer can be effectively fixed to the purlin.

[0015] Ideally, the magnetic 2s should be evenly distributed on each purlin, with a spacing of 1-2m between adjacent magnetic 2s. When the insulation layer is thicker, the distance between adjacent magnetic 2s should be smaller.

[0016] The installation process of the insulation structure is as follows: First, cover the insulation layer onto the purlins, then use magnetic attraction to press the insulation layer onto the purlins. Repeat the above steps until the insulation layer covers the entire steel structure. Because of the magnetic fixing method, it not only facilitates the installation of the insulation layer but also makes subsequent removal easy. When fire-retardant coating needs to be sprayed on the purlins, remove the insulation structure during the day when temperatures are high to allow for purlin spraying. After completion, fix the insulation structure back in place and proceed with the spraying of fire-retardant coatings on the steel columns and beams.
