DETAILED DESCRIPTION

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an insulation board with side seam flame retardant function, comprising a main board 1 and a sub-board 2, the side wall of the main board 1 is fixedly mounted with a convex plate 3, the side wall of the sub-board 2 is provided with a docking groove 4, the inner wall of the sub-board 2 is threadedly connected with a fastening bolt 5, a closing component 6 is arranged between the main board 1 and the sub-board 2, and the closing component 6 includes a filling groove 61, an arc block 62, a closing groove 63, a filling belt 64, an arc groove 65, a closing block 66, a protective rubber bag 67, a recessed groove 68 and a nozzle 69.

[0025] In one embodiment of the utility model, a filling groove 61 is provided on the side wall of the main board 1, an arc block 62 is fixedly installed on the bottom inner wall of the filling groove 61, a closed groove 63 is provided on the arc outer wall of the arc block 62, a filling belt 64 is fixedly installed on the side wall of the sub-board 2, an arc groove 65 is provided on the outer wall of the filling belt 64 away from the sub-board 2, a closing block 66 is fixedly installed on the arc inner wall of the bottom of the arc groove 65, a protective rubber bag 67 is fixedly installed on the inner wall of the closed groove 63, a recessed groove 68 is provided on the outer wall of the protective rubber bag 67, and a nozzle 69 is provided on the outer wall of the protective rubber bag 67.

[0026] Furthermore, the main board 1 and the sub-board 2 are configured to be completely identical, and the left and right ends of the main board 1 are adapted to each other, so that the main board 1 and the sub-board 2 can fit perfectly when they are matched. At the same time, the inner wall of the protruding plate 3 is provided with a through hole adapted to the fastening bolt 5, so that the protruding plate 3 is fixedly installed in the docking groove 4 by the fastening bolt 5, thereby realizing the docking installation of the main board 1 and the sub-board 2. In addition, the number of fastening bolts 5 is provided in multiple groups, and the multiple groups of fastening bolts 5 are arranged in a linear array, so that the fixed installation between the main board 1 and the sub-board 2 is more stable. At the same time, the width of the filling belt 64 is adapted to the filling groove 61, and the number of the filling groove 61 and the filling belt 64 is the same. Two groups are provided, and the two groups of filling grooves 61 and filling belts 64 are mirror-imaged on the left and right sides of the vertical central axis of the main board 1 and the sub-board 2, so that the main board 1 and the sub-board 2 are more stable when docked and installed, and the sealing effect of the connection between the main board 1 and the sub-board 2 is better. Specifically, the number of arc blocks 62 is set to be several, and the several arc blocks 62 are evenly distributed on the inner wall of the filling groove 61 in a linear array, and the arc groove 65 is adapted to the arc block 62, so that when the filling belt 64 and the filling groove 61 are docked and installed, the arc block 62 can be completely embedded in the arc groove 65, so that the docking installation between the main board 1 and the sub-board 2 is tighter.

[0027] In addition, the protective rubber bag 67 completely wraps the inner surface of the closed groove 63, and the size of the concave groove 68 is adapted to the size of the closing block 66, and the shape of the closing block 66 is consistent with the closed groove 63, so that when the filling belt 64 and the filling groove 61 are docked and installed, the closing block 66 will squeeze the protective rubber bag 67 toward the closed groove 63 to squeeze the concave groove 68, so that the protective rubber bag 67 fits more completely in the closed groove 63. Furthermore, the nozzle 69 is opened on the side of the concave groove 68 away from the center of the sub-plate 2, and the nozzle 69 is located at the side of the concave groove 68. The protective rubber bag 67 is relatively thin, so when the external temperature changes or the burning flames affect the protective rubber bag 67, the nozzle 69 will first rupture or crack, and then spray out the gas in the protective rubber bag 67. The sealing block 66 squeezes the protective rubber bag 67, so that the closed groove 63 and the arc block 62 cooperate with the arc groove 65 to achieve a sealing effect in the filling groove 61, thereby preventing the flames or high temperature in the external environment from having an adverse effect on the connection between the main board 1 and the sub-board 2, causing the main board 1 and the sub-board 2 to break and fall off.

[0028] In an embodiment of the utility model, the interior of the protective rubber bag 67 is filled with a mixture of carbon dioxide and inert gas, and the interior of the protective rubber bag 67 is filled with quicklime powder. When the protective rubber bag 67 is affected by flames or high temperatures, the protective rubber bag 67 will expand, and then crack at the nozzle 69, causing the mixture of carbon dioxide and inert gas filled in the protective rubber bag 67 to spray out to the gap between the main board 1 and the sub-board 2, and the sprayed mixture will drive the lime powder to spread outward, so as to protect the gap between the main board 1 and the sub-board 2, and reduce the damage caused by external fire to the connection between the main board 1 and the sub-board 2.

[0029] In the present invention, when in use, the convex plate 3 of the main board 1 is aligned with the docking groove 4 of the sub-board 2 for splicing and installation. At this time, the fastening bolts 5 are tightened to achieve the docking installation of the main board 1 and the sub-board 2. At the same time, through the docking of the main board 1 and the sub-board 2, the filling belt 64 is inserted into the filling groove 61, so that the arc groove 65 opened on the side of the filling belt 64 is aligned with the arc block 62, and the closing block 66 squeezes the protective rubber bag 67 set in the closing groove 63, so that the protective rubber bag 67 is deformed. The arc blocks 62 and the arc grooves 65 are arranged to form a wavy connection structure in the filling groove 61. The closing block 66 is inserted into the closing groove 63 to ensure the splicing stability of the main board 1 and the sub-board 2 in the vertical direction. When the flame enters the filling groove 61, the connection structure of the main board 1 and the sub-board 2 will not be damaged rapidly due to the direct influence of the flame, thereby ensuring the splicing stability and flame retardant effect of the main board 1 and the sub-board 2.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
