Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an installation and fixing structure for external wall insulation panels. Background Technology

[0002] External wall insulation boards are building materials used for external wall insulation. They are typically board-shaped products made of materials such as polystyrene, polyurethane, rock wool, or glass wool. They effectively reduce heat loss from buildings, improve their insulation performance, and lower energy consumption. External wall insulation boards also enhance the fire resistance and wind pressure resistance of buildings. During construction, they are usually fixed to the surface of the building's exterior walls to provide thermal insulation.

[0003] External wall insulation boards are typically fixed to the exterior wall surface using adhesives; however, this method has significant drawbacks. Firstly, the adhesive process consumes a large amount of glue, severely violating environmental protection principles. Secondly, the bonding method is susceptible to cracking due to the properties of the adhesive materials and temperature changes caused by long-term thermal expansion and contraction, significantly reducing its reliability and lifespan. Furthermore, relying solely on the insulation structure of the external wall insulation board itself is insufficient to achieve ideal insulation performance under harsh environmental conditions, resulting in considerable limitations in its application. Therefore, this improved solution was developed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an installation and fixing structure for external wall insulation boards, which provides stable installation and better insulation effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an external wall insulation board installation and fixing structure, comprising: a main keel frame for installation on the surface of an external wall, a secondary keel frame installed on the side of the main keel frame opposite to the surface of the external wall, an insulation gap being formed between the secondary keel frame and the surface of the external wall, a plurality of inner insulation layers and a plurality of outer insulation boards being provided on the secondary keel frame, an installation area for installing and fixing the inner insulation layers being formed on the secondary keel frame through an installation structure, and the outer insulation boards being fixed to the secondary keel frame by fastening components.

[0006] By adopting the above technical solution, the resulting insulation gap utilizes the low thermal conductivity, convection suppression, and radiation characteristics of air to effectively reduce heat transfer. This, combined with the inner insulation layer and outer insulation board, achieves a triple insulation effect, better adapting to harsh environments and thus achieving superior insulation performance. Furthermore, the installation structure, along with snap-fit ​​components, mechanically secures the inner insulation layer and outer insulation board, thereby enhancing installation stability.

[0007] The installation structure is further configured such that it is located between the insulation gap and the outer insulation board, and the installation area is located between the installation structure and the outer insulation board.

[0008] By adopting the above technical solution, this structure enables convenient installation of the internal insulation layer.

[0009] Further configured as follows: the secondary keel frame is composed of a number of secondary keels arranged at intervals, the installation area is formed between adjacent secondary keels, the installation structure includes a number of installation ribs arranged between adjacent secondary keels, the number of installation ribs are arranged at intervals along the length direction of the secondary keels, and each installation rib is provided with a flexible fixing strip extending on one side of the opposite insulation gap.

[0010] By adopting the above technical solution, the inner insulation layer is installed into the installation area, and a flexible fixing strip passes through the inner insulation layer. Then, bending the fixing strip will limit and fix the inner insulation layer within the installation area. This structure allows for independent fixing of each inner insulation layer, ensuring the stability of the installation and preventing a reduction in insulation performance due to misalignment between adjacent inner insulation layers. Furthermore, this fixing method is simple in structure and lower in cost.

[0011] The sub-keel is further configured such that each of the sub-keels has a hole for inserting a mounting rib, and the end of the mounting rib is bent and inserted into the hole.

[0012] By adopting the above technical solution, the mounting rib is inserted into the insertion hole, thereby realizing the convenient assembly and fixation of the mounting rib on the secondary keel, which is simple to operate and has a lower cost.

[0013] Further configured as follows: the locking component includes a locking groove disposed on the opposite side of adjacent secondary keels and several locking components installed on the external insulation board, wherein the locking groove extends along the length direction of the secondary keel to form an elongated shape.

[0014] By adopting the above technical solution and setting the slot to a long strip shape, the external insulation board can be installed and fixed at any position on the secondary keel, which has better universal adaptability.

[0015] The further configuration includes: the card fitting assembly includes a card fitting base fixedly mounted on the outer insulation plate, a card fitting block slidably mounted on the card fitting base and used for insertion into the card slot, and a return spring connecting the card fitting block.

[0016] By adopting the above technical solution, the card slot is inserted into the card groove, thereby realizing the installation and fixation of the external insulation board on the secondary keel.

[0017] The further configuration is as follows: the side of the card block facing the insulation gap is formed with a guide slope for guiding the card block to be inserted into the card slot.

[0018] By adopting the above technical solution, the setting of the guide slope allows the card block to be easily inserted into the card slot by pressing the outer insulation plate, making the assembly operation more convenient.

[0019] The design further includes: a stop strip at the bottom of the slot for restricting the movement of the outer insulation board along the length of the slot, the stop strip extending along the length of the slot.

[0020] By adopting the above technical solution, the locking block inserted into the slot is pressed against the stop strip under the action of the return spring. The frictional resistance generated between the locking block and the stop strip restricts the movement of the external insulation panel, thereby ensuring the stability of the external insulation panel installation. This avoids the phenomenon of reduced insulation effect caused by misalignment between adjacent external insulation panels in the later stage. Moreover, this fixing method has a simple structure and lower cost.

[0021] In summary, this utility model has the following beneficial effects: it is installed stably and has a better heat preservation effect. Attached Figure Description
