Description

Technical Field

[0001] The invention relates to the technical field of building energy-saving thermal insulation materials, and in detail to a board structure used in the restoration process of ancient buildings, located on the facade and having a thermal insulation effect, specifically an exterior wall insulation board for building thermal insulation. Background Art

[0002] In the process of restoring ancient buildings, modern architectural design concepts are often used. For example, the use of insulation board structure on the outer facade of the wall can not only decorate and protect the outer facade of the building, but also play a good role in building insulation. For example, the building insulation board with announcement number CN112127495B in the prior art includes an outer support plate, a sandwich plate, a round tube, a connecting tube, a square hollow block, a fastening bolt, an installation mechanism, a cylinder, a fixing block, a conical block, a sealing mechanism and a clamping mechanism. The application places a phase change material that is easy to transform in shape inside the sandwich panel. When the external temperature of the outer support plate becomes high, the phase change material is heated and transformed into a shape, and enters the upper square groove through the round tube. When the temperature outside the outer support plate decreases, the phase change material is cooled and liquefied into a liquid state, and enters the lower square groove through the round tube, thereby achieving the purpose of heat preservation of the panel. The threaded rod is rotatably installed inside the connecting pipe, and the connecting pipe is sealed by the protective cylinder and the sealing ring to prevent the phase change material from flowing out of the gap between the connecting pipe and the threaded rod in the steam state. The square rod anti-fixing block and the conical block are clamped inside the cylinder, thereby improving the stability of the stacked connection between the two building insulation boards. Or a building insulation board with announcement number CN108978915B in the prior art, comprising an insulation layer, a fireproof layer and a sound insulation layer, wherein the insulation layer comprises a No. 1 insulation layer and a No. 2 insulation layer; insulation cores are arranged in the No. 1 insulation layer and the No. 2 insulation layer; the insulation cores are made of polyurethane rigid foam; protective plates are arranged on both sides of the two insulation cores; dry soil is inside the protective plates; a gap is arranged between the No. 1 insulation layer and the No. 2 insulation layer, and a spring fixedly connected between the No. 1 insulation layer and the No. 2 insulation layer is arranged in the gap; square airbags are arranged at the upper and lower ends of the gap; the square airbags are fixedly connected between the No. 1 insulation layer and the No. 2 insulation layer; sand is filled in the square airbags; the fireproof layer is made of a mixture of Haitian silt and glass powder; the invention has a simple structure, low-cost materials, can effectively play a role in heat preservation, sound insulation and fire prevention, and has strong impact resistance; The above-mentioned existing technologies have very good effects, especially in improving the thermal insulation effect and the stability of the connection. However, in order to ensure the thermal insulation effect, the insulation board needs to be thicker, and the thicker thickness means higher transportation costs. Due to the relatively fixed thickness, the insulation board’s own protective performance and the protective performance of the relatively fragile exterior wall structure of ancient buildings are poor. Summary of the invention

[0003] The purpose of the present invention is to provide an exterior wall insulation board for building insulation, so as to solve the problem proposed in the above background technology that the insulation board needs to have a larger thickness in order to ensure the insulation effect, and the larger thickness means increased transportation cost. Also, due to the relatively fixed thickness, the insulation board's own protective performance and the protective performance of the relatively fragile exterior wall structure of ancient buildings are poor.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an exterior wall insulation board for building insulation, comprising an outer board and an inner board that constitute the whole board, wherein the outer board is used for decoration and the lower end surface of the inner board is used for contacting and connecting with the exterior wall of the ancient building, and both are provided with a vacuum space inside for building insulation, and the outer board and the inner board are also connected by a sliding mechanism, and the sliding mechanism is used to change the spacing between the outer board and the inner board, thereby adjusting the overall thickness of the insulation board, and the sliding mechanism is also used for self-locking the thickness of the outer board and the inner board before stretching.

[0005] As a further feature, the sliding mechanism comprises a sliding rod, wherein the top end of the sliding rod made of elastic material is fixed to the lower end surface of the outer plate, and in an initial state, the bottom end of the sliding rod fits into a sliding groove, which is provided in the inner plate.

[0006] As a further feature, the sliding mechanism also includes a guide rod located on the axis of the insulation board, wherein the top end of the guide rod is mounted on the outer board, and the bottom end of the guide rod is slidably connected to the center of the inner board.

[0007] As a further feature, the sliding mechanism also includes a protective spring sheet located between the outer plate and the inner plate.

[0008] As a further feature, the lower half of the slide rod is an arc-shaped structure, which in an initial state slides and fits in a slide groove which is also an arc-shaped structure, and the top opening and the bottom end of the slide groove are not on the same vertical line.

[0009] As a further feature, a cleaning mechanism is also provided on the outer surface of the outer plate, and the cleaning mechanism generates power through the movement of the outer plate and cleans the surface of the outer plate.

[0010] Furthermore, the cleaning mechanism includes an umbrella-shaped top cover installed on the top of the guide rod, and an elastic strip installed at the edge of the top cover. The elastic strip is attached to the outer surface of the outer plate, and the guide rod and the top cover are driven to rotate through the driving mechanism to clean the surface of the outer plate.

[0012] As a further feature, the bottom end of the guide rod is rotatably connected to an elastic member, and the elastic member is fixed in the inner plate to enhance the rebound effect of the guide rod, and the elastic member is made of a memory alloy material.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the exterior wall insulation board for building insulation, based on the existing insulation board with vacuum or multi-layer insulation structure, redesigns its composition mode, reduces its initial transportation cost and ensures the insulation effect after subsequent installation by means of adjustable overall thickness of the board structure, and can also utilize the adjustable thickness of the insulation board to effectively protect itself and the wall surface from impact, and can realize the effect of automatic cleaning of the board surface based on the same mechanism, which has better insulation performance for the building and is more energy-saving and environmentally friendly, as shown in the following content: 1. The structural design of the slide bar and the slide groove can utilize the sliding connection between the two to flexibly adjust the relative distance between the outer plate and the inner plate, thereby satisfying the small space occupation requirement during transportation and the insulation performance requirement after installation by changing the overall thickness of the insulation board; Furthermore, the arc-shaped structural design of the slide bar and the slide groove matching section can, on the one hand, utilize the limiting effect generated by the non-linear structure before the insulation board is thickened, so that the slide bar can be stably engaged in the slide groove to ensure the stability during transportation; on the other hand, it can utilize the characteristics of its arc-shaped structure to maintain a relatively stable state after the insulation board is thickened, thereby ensuring its stability during use; Furthermore, the elastic structure design of the slide bar itself allows the insulation board to be thickened and maintained in a relatively stable state. When it is blown by strong wind or other external forces, the elastic deformation of the slide bar itself and the synchronous movement of the outer plate can effectively decompose the impact force, thereby achieving effective protection of the board and the wall. 2. The structural design of the twisted rod, the top cover and the elastic strip enables the outer plate to convert the vertical movement into the rotation of the top cover and the elastic strip when driving the guide rod to move synchronously, thereby realizing automatic cleaning of the plate surface; Furthermore, the use of the elastic part at the bottom of the guide rod can, on the one hand, help the outer panel to rebound stably as a whole, and on the other hand, can utilize the characteristics of its own memory alloy material to actively pull the outer panel to move in a high or low temperature environment, thereby achieving the effect of automatically cleaning the panel structure.

[0016] 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.

[0017] See also Figure 1-Figure 8 , the present invention provides the following technical solutions: Embodiment 1: The content disclosed in this embodiment is to solve the problems existing in the prior art, such as Figure 1-Figure 2The scheme shown includes an outer panel 1 and an inner panel 2 that constitute the whole panel, wherein the outer panel 1 is used for decoration and the lower end surface of the inner panel 2 is used for contacting and connecting with the outer wall of the ancient building, and both are provided with a vacuum space inside for building insulation, and the outer panel 1 and the inner panel 2 are also connected by a sliding mechanism, and the sliding mechanism is used to change the spacing between the outer panel 1 and the inner panel 2, thereby adjusting the overall thickness of the insulation panel, and the sliding mechanism is also used for self-locking of the thickness of the outer panel 1 and the inner panel 2 before stretching, and the sliding mechanism includes a sliding rod 5, wherein the top end of the sliding rod 5 made of elastic material is fixed to the lower end surface of the outer panel 1, and the bottom end of the sliding rod 5 in the initial state is fitted in the sliding groove 6, and the sliding groove 6 is provided in the inner panel 2, and the sliding mechanism also includes a guide rod 3 located on the axis of the insulation panel, wherein the top end of the guide rod 3 is installed on the outer panel 1, and the bottom end of the guide rod 3 is slidably connected to the center of the inner panel 2, and the sliding mechanism It also includes a protective spring piece 4 located between the outer plate 1 and the inner plate 2. In the initial state, the slide bar 5 is fitted in the slide groove 6, so that the spacing between the outer plate 1 and the inner plate 2 is smaller, and the overall thickness of the insulation board is thinner, which can ensure its efficiency during transportation or handling. When the insulation board needs to be installed, the staff directly pulls the outer plate 1 away from the inner plate 2, so that the slide bar 5 will be pulled out of the slide groove 6, and the slide bar 5 will synchronously slide in the inner plate 2, thereby improving the stability of the adjustment. After the adjustment, the existing means can be used to fix the state after the thickness is increased, thereby increasing the heat loss path by separating the inner plate 2 and the outer plate 1, and improving the insulation effect. The spring piece 4 located in the inner plate 2 and the outer plate 1 can ensure the sealing effect between the inner and outer plate structures after the thickness of the insulation board is adjusted by its own deformation.

[0018] The content disclosed in this scheme is equivalent to a locking mechanism, which is also composed of a slide bar 5 and a slide groove 6, and the purpose is to maintain the state of the insulation board before and after the thickness is adjusted without using additional locking means. For specific reference Figure 3-Figure 6 The lower half of the slide bar 5 is an arc-shaped structure, which slides and fits in the slide groove 6 which is also an arc-shaped structure in the initial state. At the same time, the top opening and the bottom end of the slide groove 6 are not on the same vertical line. The lower half of the slide bar 5 is an arc-shaped structure, and the corresponding slide groove 6 is also the same. Therefore, without the interference of significant external force, the slide bar 5 will not be deformed and will not escape from the slide groove 6. Therefore, the insulation board as a whole can be maintained in a predetermined state before thickening. Moreover, due to the design of the arc-shaped structure, after the slide bar 5 is completely out of the slide groove 6, the bottom end of the slide bar 5 will directly contact the surface of the inner plate 2 on the side of the slide groove 6. That is to say, since the top opening of the slide groove 6 and the bottom end of the slide bar 5 after sliding out are misaligned with each other, the insulation board can be maintained in a predetermined state after thickening. The design of the above scheme can not only adjust the overall thickness of the insulation board to adapt to different stages, but also have another technical effect. Due to the serious aging of the architectural structure of the ancient building, not only the paint and other structures of the exterior wall are seriously peeling off, but the difficulty of repair will also increase sharply. Therefore, extra attention is also required when fitting and fixing the insulation board. At the same time, external force environment such as strong winds can easily cause the wall to be subjected to greater force. The insulation board in this scheme can effectively buffer this type of external force during use, and its buffering effect is still brought by the slide rod 5 that slides out of the slide groove 6. Since the slide rod 5 will be separated from the secondary contact with the slide groove 6 after sliding out, and it itself is also an elastic material, when the wind is strong or other external forces act on the insulation board, its outer panel 1 will effectively release the impact force by repeatedly compressing the slide rod 5 to deform, thereby better protecting the ancient building.

[0019] Embodiment 2: In this embodiment, a solution is disclosed in which an external force is used to guide the outer plate 1 to reciprocate while driving the cleaning mechanism to clean the outer surface of the insulation board. For details, please refer to Figure 7-Figure 8 The outer surface of the outer plate 1 is also provided with a cleaning mechanism, which generates power through the movement of the outer plate 1 and cleans the surface of the outer plate 1. The cleaning mechanism includes an umbrella-shaped top cover 7 installed on the top of the guide rod 3, and an elastic strip 8 installed at the edge of the top cover 7. The elastic strip 8 is attached to the outer surface of the outer plate 1, and the guide rod 3 and the top cover 7 are driven by the driving mechanism to rotate and clean the surface of the outer plate 1. The driving mechanism includes a twisted rod 9 fixed inside the inner plate 2, and the top end of the twisted rod 9 is threadedly connected to the bottom end of the guide rod 3. The guide rod 3 is rotatably connected to the outer plate 1, and the guide rod 3 is movably connected to the inner plate 2. When the wind or external force drives the outer plate 1 to move, the guide rod 3 will move synchronously with the outer plate 1. Therefore, under the threaded transmission action of the guide rod 3 and the twisted rod 9, the guide rod 3 will be in a rotating state synchronously. At this time, the top cover 7 will drive the elastic strip 8 to rotate together and produce a cleaning effect.

[0020] In this embodiment, another scheme for guiding the displacement of the outer plate 1 is disclosed. Unlike the above scheme in which the insulation plate is deformed by uncontrollable factors such as external force, the surface of the outer plate 1 is cleaned by active deformation in this scheme, and the deformation principle is also the same as Figure 8As shown, the bottom end of the guide rod 3 is rotatably connected to an elastic member, and the elastic member is fixed in the inner plate 2 to enhance the rebound effect of the guide rod 3. At the same time, the elastic member is a memory alloy material. The elastic member is used to sense the external temperature. The deformation temperature threshold control is related to the alloy composition. It is a prior art and is not elaborated here. Specifically, when the external temperature reaches the threshold, the internal temperature of the insulation board will change accordingly, and guide the elastic member to actively deform, thereby pulling the guide rod 3 to move with the outer plate 1. The reason why the outer plate 1 is automatically moved by controlling the temperature is to meet the local climatic conditions. In the summer or winter time periods when the temperature changes significantly, the local area is in a windy or dusty environment, and the cleaning frequency of the board surface should be higher. Therefore, the above content is adopted in this scheme, which can achieve a good automatic cleaning effect of the board surface, reduce labor input, and be more energy-saving and environmentally friendly.

[0021] 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.
