Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically to a sealing and fixing structure at a variable-section location of a building exterior wall thermal insulation layer. Background Art

[0002] Rock wool board, also known as rock wool insulation decorative board, is a type of exterior wall insulation material. It is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. It has the characteristics of light weight, low thermal conductivity, fire resistance, heat preservation and sound insulation, so it is widely used in the market.

[0003] Currently, traditional construction methods are commonly used for additional insulation layers. Because the base insulation layer and the top decorative layer have already been constructed and have been exposed to the elements for a long time, using traditional adhesives and crack-resistant mortar to construct additional insulation layers can easily cause cracking at the variable cross-section at the top of the additional layer, causing the additional insulation layer to separate from the base insulation layer and leaking through the cracks, posing a certain system safety risk.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] In order to overcome the deficiencies in the prior art, a sealing and fixing structure for a building exterior wall insulation layer with a variable cross-section is provided, which improves the sealing, stability and overall durability of the added insulation layer.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A sealing and fixing structure for a building exterior wall insulation layer at a variable cross-section includes a bottom insulation layer, a structural body disposed outside the bottom insulation layer, and a connector. The structural body includes a mortar bonding layer, an insulation board, and an external finishing layer disposed sequentially from the inside out. One side of the connector is fixedly disposed on the bottom insulation layer, and the other side of the connector is disposed outside the insulation board. The upper end of the connector is closed, and the lower end is provided with an opening for inserting the insulation board.

[0008] The side of the connector close to the bottom insulation layer is in contact with the side surface of the bottom insulation layer, and the upper end of the connector and the bottom insulation layer are sealed by ketone weather-resistant sealant.

[0009] Preferably, the connecting member includes an inner plate, an outer plate and an inclined plate. The inner plate and the outer plate are arranged in parallel, the upper end of the inner plate is higher than the outer plate, the lower end of the inner plate is lower than the outer plate, and the two ends of the inclined plate are respectively connected to the upper ends of the inner plate and the outer plate.

[0010] Preferably, a plurality of reserved holes are equidistantly provided on the lower side of the inner plate, and the inner plate is fixedly connected to the outer wall of the building by anchor bolts passing through the reserved holes.

[0011] Preferably, the thickness of the outer panel is less than the thickness of the outer finishing layer.

[0012] Preferably, the insulation board is a rock wool composite insulation board.

[0013] Preferably, the thickness of the inner plate, outer plate and inclined plate is 2-3 mm.

[0014] Preferably, the inner plate and the inclined plate are an integral structure, and the outer plate and the inclined plate are detachably connected.

[0015] Preferably, a slot is provided on the lower side of one end of the inclined plate close to the outer plate, a protrusion is provided on the lower side of the slot, an insert block that cooperates with the slot is fixedly connected to the inner side of the outer plate, a positioning groove that cooperates with the protrusion is provided on the lower side of the insert block, and when the outer plate is parallel to the inner plate, the protrusion is inserted in the positioning groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model connects the variable cross-section of the insulation layer through a connector. Because the connector is rigidly connected to the building's exterior wall, it can prevent cracking between the top and bottom insulation layers, which could lead to the risk of the insulation layer separating from the bottom insulation and leaking through the cracks. The connector runs the entire length of the bottom insulation layer, and anchor bolts secure the rock wool composite insulation board to the base insulation layer. This improves the safety and waterproof sealing of the exterior wall insulation system while ensuring the integrity of the entire system. BRIEF DESCRIPTION OF THE DRAWINGS
