Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to an exterior wall fireproof and heat-insulating rock wool board. Background Art

[0002] Rock wool board is a fireproof material, which is widely used in construction projects due to its characteristics of light weight, small thermal conductivity, sound insulation, heat absorption and Class A fireproof performance.

[0003] When a fire occurs, the rock wool board installed and fixed on the wall can effectively isolate the fire and slow down the spread of the fire. However, due to the expansion of air when heated, gaps or bulges will be generated between the rock wool board and the wall. In the current installation of rock wool boards, each rock wool board is installed independently, so the force on each rock wool board is independent, resulting in the easy single-piece detachment of the rock wool board, causing gaps in the fireproof line formed by the rock wool board and greatly reducing the fire isolation effect of the rock wool board.

Detailed Description of the Embodiment

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0029] Embodiment: An exterior wall fireproof and heat-insulating rock wool board, refer to Figures 1 - 3 , including: a plate body 1; a glue storage bin 41 is provided on the right side of the plate body 1, and an adhesive for adhering the plate body 1 is stored in the glue storage bin 41. A glue outlet 42 for discharging the adhesive is provided on the right side of the glue storage bin 41, and a plug that can be pushed open by the adhesive is provided at the glue outlet 42; a glue pushing rod 4 is slidably installed in the glue storage bin 41. The cross-sectional dimension of the bottom of the glue pushing rod 4 is the same as the cross-sectional dimension of the glue storage bin 41. When the glue pushing rod 4 moves upward, it will push the adhesive in the glue storage bin 41 to push open the plug and discharge it from the glue outlet 42; a lead screw 43 fixedly installed at the upper end of the glue pushing rod 4, and the end of the lead screw 43 extends out of the plate body 1 from the glue storage bin 41; a nut 44 threadedly installed on the lead screw 43, and rotating the nut 44 will control the up and down movement of the lead screw 43.

[0030] When installing the rock wool board, first use fixing parts to fixedly install the rock wool board on the wall. When two adjacent rock wool boards are installed, at this time, the adjacent sides of the two rock wool boards are in contact with each other. Rotate the nut 44 on the left rock wool board to discharge the adhesive from the glue outlet 42. After the glue outlet 42 pushes open the plug, it can automatically seal the position between the two adjacent rock wool boards. After the adhesive dries, the two adjacent rock wool boards can be connected together;

[0031] Therefore, when a fire occurs and the air temperature rises and expands, when the expanded air acts on the rock wool board irregularly, the force exerted by the expanded air on the rock wool board can be evenly distributed on all the connected rock wool boards. The force is evenly spread and reduced. Coupled with the connection between the rock wool boards, it can prevent the single-piece detachment of the rock wool board, so that the fireproof line formed by the rock wool board can be kept intact and reduce the impact of the expansion of high-temperature air on the fireproof effect of the rock wool board.

[0032] Refer to Figure 4 , a circular groove 46 is provided on the glue pushing rod 4. The upper part of the circular groove 46 is a plane 461, and the lower part of the circular groove 46 is an inclined plane 462; a convex groove pattern 47 is provided on the upper part of the glue storage bin 41. The convex groove pattern 47 can be stuck into the circular groove 46 and cooperate with the plane 461 or the inclined plane 462 to unidirectionally limit the moving direction of the glue pushing rod 4; the lead screw 43 and the glue pushing rod 4 are fixed through a neck-breaking groove 45, and the neck-breaking groove 45 will break when stressed.

[0033] When the lead screw 43 rotates to drive the glue pushing rod 4 to move upward, the convex groove pattern 47 contacts the inclined surface 462 of the annular groove 46, and the convex groove pattern 47 is deformed by the extrusion of the inclined surface 462, so the convex groove pattern 47 does not affect the upward movement of the glue pushing rod 4; when the bottom of the glue pushing rod 4 contacts the inner top of the glue storage bin 41, the glue pushing rod 4 can no longer move upward, while the lead screw 43 can still move upward, so after the neck-breaking groove 45 is stretched, it will break, so the lead screw 43 and the nut 44 can be taken away from the plate body 1, facilitating the subsequent splicing and installation of the rock wool board in the up and down directions; while the glue pushing rod 4 remains in the plate body 1, the bottom of the glue pushing rod 4 is restricted by the glue storage bin 41 and cannot move upward relative to the plate body 1, and under the combined action of the flat surface 461 and the convex groove pattern 47, the glue pushing rod 4 cannot move downward relative to the plate body 1, so the glue pushing rod 4 is still fixed on the plate body 1 and blocks the glue storage bin 41, preventing moisture from entering the glue storage bin 41 and causing water penetration of the plate body 1, reducing the impact on the fire resistance of the plate body 1, thereby minimizing the impact of the space occupied by the glue pushing rod 4 and the glue storage bin 41 on the rock wool board.

[0034] Refer to Figures 1 - 2 , a claw groove 31 is formed on the plate body 1, and further includes: a claw 3 fixedly installed on the plate body 1, and the positions of the claw 3 / claw groove 31 on the left side of the plate body 1 are matched with the positions of the claw 3 / claw groove 31 on the right side of the plate body 1, so that the two plate bodies 1 can be docked and matched in the left and right directions. When two adjacent rock wool boards are butted together in the left and right directions, the claw 3 on one of the rock wool boards can be inserted into the card slot on the other rock wool board, further fixing the two rock wool boards and strengthening the connection effect between the rock wool boards.

[0035] Refer to Figure 1 , heat conduction grooves 2 for heat dissipation are formed around the plate body 1, and the heat received by the plate body 1 can be dissipated from the heat conduction grooves 2, reducing the expansion coefficient of the air between the rock wool board and the wall, and reducing the force exerted by the expanding air on the rock wool board.

[0036] Refer to Figures 1 - 3 , further includes: a gasket 5 fixedly installed below the nut 44, and the gasket 5 is clamped between the nut 44 and the plate body 1. The gasket 5 can reduce the pressure of the nut 44 on the plate body 1 and reduce the damage of the nut 44 to the plate body 1.

[0037] Refer to Figure 2 , an adhesive groove 6 is formed at the position on the plate body 1 for the adhesion of the adhesive. When the adhesive is discharged, it will be extruded into the adhesive groove 6 and air-dried and adhered in the adhesive groove 6, and the adhesive groove 6 can increase the unevenness of the contact surface of the adhesive, thereby providing a better gripping point for the adhesive, that is, the adhesive groove 6 improves the connection effect between the rock wool boards by improving the adhesion effect of the adhesive.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
