Description

Technical Field

[0001] This utility model relates to the field of modular building technology, and in particular to a fireproof sealing node structure for modular building joints. Background Technology

[0002] Currently, during the construction of modular buildings, fireproof sealing nodes are installed at the ends of the joints between the building modules to prevent the spread of fire in the event of a fire outside the building.

[0003] Among them, a search revealed that Chinese patent CN220414543U discloses a modular box connection joint structure. In the application of the above-mentioned patent's technical solution, the sealing and protective structure of the joint sealing is not firmly connected and installed, resulting in poor performance of the protective structure. Therefore, in order to better realize the connection and protection function of modular buildings, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the fireproof sealing node structure in the prior art. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of unstable connection and installation of the sealing and protection structure of existing modular building joint sealing, and to propose a modular building joint fireproof sealing node structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular building joint fireproof sealing node structure includes two modular building blocks, a filling block between the two modular building blocks, and a fireproof strip between the two modular building blocks. The fireproof strip is located on one side of the filling block. Multiple installation slots are provided on both sides of the fireproof strip. A connecting component is provided in the installation slot. The connecting component includes a connecting box, which is fixed in the installation slot by bolts. An elastic sheet is fixedly connected to one side of the inner wall of the connecting box, and one end of the elastic sheet contacts one side of the modular building block.

[0007] Furthermore, the filling block is made of concrete and connects the two modular building blocks together.

[0008] Furthermore, the fireproof strip is a rubber strip.

[0009] Furthermore, a fireproof cover is fixedly connected to one side of the connection between the two modular building blocks, and a first protrusion is fixedly connected to the inner walls of both sides of the fireproof cover.

[0010] Furthermore, a connecting seat is fixedly connected to one side of the modular building block, and a second protrusion is fixedly connected to one side of the connecting seat, with the second protrusion engaging with the first protrusion.

[0011] Furthermore, a support strip is fixedly connected to one inner wall of the fireproof cover, and the support strip is in contact with the fireproof strip.

[0012] Furthermore, a sealing strip is snapped onto one end of the fireproof cover, and the sealing strip contacts the modular building block.

[0013] Furthermore, the fireproof cover is a PVC cover.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By using the elasticity of the elastic sheet to press one end against the modular building block, the connection between the fireproof strip and the modular building block is strengthened, thereby improving the effectiveness of the protective structure.

[0016] 2. The installation of fireproof strips and fireproof covers can play a dual role in fire prevention, thereby effectively spreading the fire. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A modular building joint fireproof sealing node structure includes two modular building blocks 1, a filling block 2 between the two modular building blocks 1, and a fireproof strip 3 between the two modular building blocks 1. The fireproof strip 3 is located on one side of the filling block 2 and fills the space between the two modular building blocks 1, thereby spreading the fire when a fire occurs.

[0025] Multiple mounting slots 4 are provided on both sides of the fireproof strip 3. A connecting component 5 is provided in the mounting slot 4. The connecting component 5 includes a connecting box 501. The connecting box 501 is fixed in the mounting slot 4 by bolts. An elastic sheet 502 is welded to the inner wall of one side of the connecting box 501. One end of the elastic sheet 502 contacts one side of the modular building block 1. Under the elastic action of the elastic sheet 502, one end of the elastic sheet 502 abuts against the modular building block 1, thereby strengthening the connection between the fireproof strip 3 and the modular building block 1.

[0026] The filling block 2 is made of concrete and connects two modular building blocks 1 together. The fireproof strip 3 is a rubber strip. A fireproof cover 6 is fixed to one side of the connection between the two modular building blocks 1 by bolts. The inner walls of both sides of the fireproof cover 6 are integrally formed with first protrusions 7. A connecting seat 9 is fixed to one side of the modular building block 1 by bolts. A second protrusion 10 is integrally formed on one side of the connecting seat 9. The second protrusion 10 is engaged with the first protrusion 7. The fireproof cover 6 is covered on the outside of the connection between the two modular building blocks 1 by the engagement of the first protrusion 7 and the second protrusion 10.

[0027] A support strip 11 is integrally formed on one side of the inner wall of the fireproof cover 6. The support strip 11 contacts the fireproof strip 3, thereby improving the sturdiness of the fireproof cover 6. A sealing strip 8 is snapped onto one end of the fireproof cover 6. The sealing strip 8 contacts the modular building block 1. The fireproof cover 6 is a PVC cover. By using a rigid PVC cover, the fireproof cover 6 has good fireproof and flame-retardant properties and effectively prevents moisture penetration.

[0028] The working principle of this embodiment is as follows: In use, the fireproof strip 3 is filled between two modular building blocks 1, thereby preventing the spread of fire in the event of a fire. The fireproof strip 3 is made of high-temperature resistant rubber, which improves its weather resistance and aging resistance, making it suitable for use in a temperature range of -50℃ to 150℃. Then, under the elastic action of the elastic sheet 502, one end of the elastic sheet 502 abuts against the modular building block 1, thereby strengthening the connection between the fireproof strip 3 and the modular building block 1. Next, the fireproof cover 6 is covered on the outside of the connection between the two modular building blocks 1 by the snap-fit ​​of the first protrusion 7 and the second protrusion 10, thereby playing a fireproof role from the outside and improving the fireproof function. The fireproof cover 6 is made of PVC, which gives it good fireproof and flame-retardant properties and effectively prevents moisture penetration. The support strip 11 contacts the fireproof strip 3 to improve the sturdiness of the fireproof cover 6, thus ensuring the performance of the fireproof cover 6.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
