For example, a rock wool board with announcement number CN209443605U in the prior art includes a rock wool board, the rock wool board includes an upper rock wool board and a lower rock wool board, a support plate is arranged between the upper rock wool board and the lower rock wool board, reinforcing ribs are arranged on the support plate, a waterproof membrane is arranged on the upper surface of the upper rock wool board and the lower surface of the lower rock wool board, a sealing plate is arranged on the periphery of the rock wool board, the sealing plate is fixedly connected to the support plate, the sealing plate is sealed and connected to the periphery of the rock wool board, and the sealing plate is provided with fixing claws. The rock wool board in this application has high strength and waterproof performance, which avoids the phenomenon that the rock wool board falls off due to poor waterproof performance and low strength during use.

The spliced ​​rock wool board, through the arrangement of the connection block, the connection groove, the fixed block and the support bar, inserts the connection block on one side of the first rock wool board into one side of the connection groove and fits with the support bar. Due to the arrangement of the connection block and the support bar, the size of the contact surface when the first rock wool board and the second rock wool board are bonded can be increased, thereby improving the stability of the first rock wool board and the second rock wool board after splicing.

[0004] It is not difficult to know that the conventional designs or improvement directions in the current field represented by the above-mentioned prior art are mostly focused on improving the waterproof performance of rock wool boards and improving the convenience of installation. However, the rock wool boards themselves are used on the facades of buildings, and aging and cracking caused by long-term wind and sun exposure cannot be completely avoided. Therefore, after water vapor invades the interior of the rock wool board, its accelerated aging and falling off cannot be fundamentally improved. Summary of the invention

[0005] The purpose of the present invention is to provide a green building exterior wall insulation rock wool board to solve the problem mentioned in the above background technology that the rock wool board itself is used on the building facade, and aging and cracking caused by long-term wind and sun exposure cannot be completely avoided. Therefore, after water vapor invades the interior of the rock wool board, its accelerated aging and shedding cannot be essentially improved.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a green building exterior wall insulation rock wool board, including an outer plate and an inner plate that constitute the whole rock wool board and are separated in an initial state, and also including a frame that is glued or snap-fitted on the inner surface of the inner plate and used to connect to the wall surface, wherein a positioning column perpendicular to the outer plate is installed in the frame, and the top of the positioning column is also connected to a vertical cylinder for positioning and splicing the outer plate, wherein a heating mechanism is also provided in the vertical cylinder for removing moisture that invades the rock wool board to improve the insulation effect.

[0007] As a preferred solution: the heating mechanism includes an electric heating element and a cable connected thereto and supplying power, wherein the cable passes through the positioning column and is connected to an external power source.

[0008] As a preferred solution: a micro-hole for water vapor to enter is opened at the top of the vertical tube, and the heating structure inside the vertical tube is used to generate heat after contact with water vapor and dissipate it through the vertical tube itself or the gap at the detachable connection between the vertical tube and the positioning column.

[0009] As a preferred solution: the heating mechanism is provided with two upper and lower groups in the vertical tube, and the two adjacent groups are blocked by a partition, wherein the heating mechanism deforms after absorbing moisture and releasing heat, and when the moisture exceeds a threshold, the heating mechanism deforms and breaks through the partition, allowing the other heating mechanism to absorb moisture and trigger heating.

[0010] As a preferred solution: the heating mechanism includes a containing bag for containing water-heating medium, and the containing bag is fixed to the side wall inside the vertical tube through a mesh plate, and the two ends of the mesh plate are non-closed to provide deformation space for the containing bag.

[0011] As a preferred solution: a heat-conducting mechanism is nested and installed at the connection between the vertical tube and the positioning column, wherein the heat-conducting mechanism is used to guide and dissipate the heat in the vertical tube to other areas of the rock wool board.

[0012] As a preferred solution: the heat conduction mechanism includes a heat conduction plate which is vertically distributed in an initial state and a horizontal bar for connecting the heat conduction plate and the ring body, wherein the horizontal bar is also used to pass through the side wall of the positioning column and extend into the interior of the positioning column, while the ring body is nested outside the positioning column.

[0013] As a preferred solution: a platform protruding from the surface is provided at the inner edge of the horizontal bar, and a vertical bar fixed to the bottom wall of the vertical tube is provided above the platform. After the outer plate is installed and the vertical tube is pressed, the vertical bar contacts the platform, driving the horizontal bar to deflect slightly in the ring wall of the ring body, guiding the claws at the top of the heat conducting plate to obliquely penetrate the outer plate.

[0014] As a preferred solution: the connection between the heat conducting sheet and the horizontal bar is made of a memory alloy material, which will deform and guide the heat conducting sheet to flip when the heat exceeds a threshold.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the green building exterior wall insulation rock wool board redesigns the structural composition of the rock wool board, and achieves effective dehumidification and auxiliary fire protection of the rock wool board itself by improving the structural composition without changing the chemical composition of the rock wool board, thereby reducing the difficulty of the rock wool board in market promotion and improving the durability and safety of the rock wool board itself, making it more suitable for use in a green building system, as shown in the following content.

[0016] The use of positioning columns, vertical tubes and frames can achieve segmented connection between the whole board and the wall by designing the integrated rock wool board in layers, so that the boards of different layers are matched with the positioning columns and vertical tubes respectively. At the same time, the reinforcement connection between the frame and the wall and the splicing of the whole frame and the rock wool board can reduce the difficulty of subsequent disassembly and replacement. In addition, the rock wool board can be replaced in layers in a targeted manner after aging, without the need for replacing the entire board, which is more energy-saving and environmentally friendly. As a further step, by using a heating mechanism in the vertical cylinder, the vertical cylinder itself can not only serve as a guiding and stabilizing mechanism for the layered installation of the rock wool board, but also can utilize its positional characteristics deep in the center of the rock wool board after installation to cooperate with its own heating function to achieve efficient dehumidification, thereby delaying further aging of the rock wool board and ensuring the thermal insulation effect; As a further step, by designing a heat conducting sheet in the rock wool board, on the one hand, the vertical distribution in the initial state and its plug-in fit with the rock wool board can be used to achieve connection reinforcement, and on the other hand, the contact with the vertical cylinder can be used to conduct heat more comprehensively and evenly, thereby achieving efficient dehumidification; Furthermore, by adjusting the deformation mode of the heat conductive plate after being heated, the heat deformation property of the memory alloy can be utilized to make the outer high-temperature plate fall off quickly in the event of a fire, thereby preventing the fire from spreading further and affecting the building structure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 11 , the present invention provides the following technical solutions: Embodiment 1: The solution disclosed in this embodiment is as follows Figure 1-4As shown, it not only solves the problem of the rock wool board being replaced or installed in an unstable and easy-to-fall-off state in the prior art, but also solves the problem of the rock wool board being entered with water vapor due to aging of the outer layer and reducing the thermal insulation performance. It includes an outer plate 1 and an inner plate 2 which constitute the whole rock wool board and are separated in the initial state, and further includes a frame 3 which is glued or snapped on the inner surface of the inner plate 2 and used to be connected to the wall. A positioning column 4 which is perpendicular to the outer plate 1 is installed in the frame 3. The top of the positioning column 4 is also connected to a vertical cylinder 5 for positioning and splicing the outer plate 1, wherein a heating mechanism is also arranged in the vertical cylinder 5 for removing the moisture invading the rock wool board and improving the thermal insulation effect. The heating mechanism includes an electric heating element and a cable connected thereto and powered by electricity, wherein the cable passes through the positioning column 4 and is connected to an external power supply, wherein the frame 3 is used to be connected to a wall bolt or other stable fixed connection method, and the frame 3 is used to be relatively easy to disassemble with the inner plate 2 by gluing or the like. At the same time, since the rock wool board is divided into an inner layer and an outer layer, when faced with a scenario where replacement is required, you can try to replace the outer plate 1 of the outer layer first, and since the connection and separation of the outer plate 1 and the vertical tube 5 and the inner plate 2 in the rock wool board body are simpler, the problems existing in the prior art are solved. At the same time, since an electric heating element is used in the vertical tube 5, when water vapor intrusion occurs or a significant decrease in the thermal insulation effect of the building is detected, the electric heating element is started to heat the vertical tube 5 to evaporate water vapor as much as possible to improve the thermal insulation effect. Although this increases the overall cost of the rock wool board, the overall structure of the frame 3 of the rock wool board itself is not replaced unless necessary, and the replacement of the inner and outer layers of the board does not involve the overall replacement of the frame 3. At the same time, the heat stably generated by the operation of the electric heating element can also be better heated, thereby reducing the replacement frequency of the rock wool board. Therefore, the resulting technological progress and effects can overflow and cover the cost.

[0021] A microhole for water vapor to enter is provided at the top of the vertical tube 5, and the heating structure inside the vertical tube 5 is used to generate heat after contacting with water vapor and dissipate it through the vertical tube 5 itself or the gap at the detachable connection between the vertical tube 5 and the positioning column 4. The heating mechanism is arranged in two upper and lower groups in the vertical tube 5, and the two adjacent groups are blocked by a partition 8. The heating mechanism deforms after absorbing moisture and releasing heat, and when the moisture exceeds a threshold, the heating mechanism deforms and squeezes through the partition 8, so that the other heating mechanism absorbs moisture and triggers heating.

[0022] Embodiment 2: The content disclosed in this embodiment is another heating solution. Compared with embodiment 1, this solution is more energy-saving and environmentally friendly, mainly because it avoids the use of electrical equipment and the cost of cable layout. However, the disadvantage is that the heating mechanism including the vertical cylinder 5 needs to be replaced regularly. Figure 5-Figure 7As shown in the figure, the heating mechanism includes a containing bag 7 for containing a water-heating medium, and the containing bag 7 is fixed to the side wall inside the vertical tube 5 through a mesh plate 6. At the same time, the two ends of the mesh plate 6 are non-closed and used to provide a deformation space for the containing bag 7. Since the water vapor intrusion of the rock wool board is mostly caused by the cracking of the outer layer, which causes the water vapor to intrude from the outside to the inside, and in a few cases, it intrudes from the inside to the outside, so a microhole for water vapor to enter is opened at the top of the vertical tube 5, and a gap is set at the bottom connection of the vertical tube 5, so that after the water vapor enters the interior of the vertical tube 5, it will firstly contact with the insulation. The rock wool board is in contact with the storage bag 7 above or below the layer 8, and after entering the storage bag 7, it will react with quicklime and other water-generating heat-generating media. Taking quicklime as an example, after contacting water vapor, it will not only generate heat but also expand in volume, and the expansion amplitude depends on the amount of water vapor. Therefore, when there is too much water vapor, the storage bag 7 will be excessively deformed and an extrusion force will be generated to rupture the interlayer 8, thereby realizing a segmented or specified direction of triggering the heating mechanism according to the direction and amount of water vapor intrusion, so that the heating effect achieved is better, and the thermal insulation performance of the rock wool board can be better restored.

[0023] Embodiment 3: The scheme disclosed in this embodiment is to improve the influence of the heat generated by the heating mechanism on the whole rock wool board, thereby further improving the thermal insulation effect of the rock wool board after humidification. Figure 8-Figure 10As shown, a heat-conducting mechanism is nested and installed at the connection between the vertical tube 5 and the positioning column 4, wherein the heat-conducting mechanism is used to guide and dissipate the heat in the vertical tube 5 to other areas of the rock wool board, and the heat-conducting mechanism includes a heat-conducting sheet 9 which is vertically distributed in an initial state, and a horizontal bar 10 for connecting the heat-conducting sheet 9 and the ring body 11, wherein the horizontal bar 10 is also used to pass through the side wall of the positioning column 4 and extend to the inside of the positioning column 4, and the ring body 11 is nested on the outside of the positioning column 4, and a platform protruding from its surface is provided at the inner edge of the horizontal bar 10, and a vertical bar 12 fixed to the bottom wall of the vertical tube 5 is provided above the platform. After installing the outer panel 1 and pressing the vertical tube 5, the vertical bar 12 contacts the platform, drives the horizontal bar 10 to deflect slightly in the ring wall of the ring body 11, and guides the claws at the top of the heat-conducting sheet 9 to obliquely penetrate into the outer panel 1, wherein the function of the heat-conducting sheet 9 itself is to conduct The heat in the vertical tube 5, but it itself can be used as a reinforcement between the outer panel 1 and the vertical tube 5 after the outer panel 1 is installed, and after the outer panels 1 are spliced ​​one by one, the center of the outer panel 1 can be directly pressed to guide the further displacement of the vertical tube 5, so that the horizontal bar 10 drives the heat conductive sheet 9 to rotate slightly through the movement of the vertical bar 12, so that it changes from a vertical state relative to the rock wool board to an inclined state, so that the claws at the edge of the heat conductive sheet 9 can enter into the outer panel 1, thereby achieving a reinforcement effect, and the connection method between the vertical tube 5 and the positioning column 4 can be a simple static friction connection or a snap connection / threaded connection with a vertical movement space margin, etc. For example, a slip ring 13 that can slide along the axis is set at the bottom end of the vertical tube 5, and the slip ring 13 is threadedly connected to the positioning column 4, etc., which are not elaborated here.

[0024] In this embodiment, a solution is also extended. The situation dealt with by this solution is relatively rare, but once triggered, it can play an extremely important role, such as Fig.11 As shown, the connection between the heat conductive sheet 9 and the horizontal bar 10 is a memory alloy material, which will deform and guide the heat conductive sheet 9 to flip after the heat exceeds the threshold. When a fire occurs on the exterior wall of a building, although flame retardant materials are used as the material of the rock wool board itself in the prior art, flame retardancy does not mean that it will not melt, etc. The transfer of such high temperature can easily cause other materials to catch fire or abnormally high temperature to cause serious damage to the building structure. Therefore, in extreme situations such as fire, the heat conductive sheet 9 will deflect accordingly, and the deflection direction can be set in advance according to the situation, so as to prevent the heat conductive sheet 9 from being damaged. Fig.11 For example, when the heat conductive sheet 9 is flipped to a horizontal state, the inner and outer layers of the rock wool board will be separated accordingly. At the same time, without the limitation of the heat conductive sheet 9, the melted rock wool board will be more easily fallen off from the wall, thereby avoiding further affecting the wall structure. If it is designed to be preheated and flipped to a vertical state, it can be used as a driving force for striking, thereby accelerating the falling off of the outer panel 1 and avoiding further spread.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
