Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, and in particular to a novel composite insulation board that is easy to reinforce. Background Technology

[0002] Insulation boards are a type of sheet-like thermal insulation material used in the construction and industrial fields. Their main function is to impede heat flow, thereby providing thermal insulation. They are usually made of materials with low thermal conductivity, such as polystyrene, rock wool, or polyurethane. By reducing the exchange of heat between indoors and outdoors, insulation boards can effectively improve the energy efficiency of buildings, reduce heating and cooling energy consumption, and improve the comfort of living and working environments. They are widely used in insulation projects for walls, roofs, and pipes. Traditional insulation boards are typically reinforced using only expansion screws. However, expansion screws are prone to loosening and cannot achieve a very firm effect during pull-out tests, resulting in poor test results and inaccurate experimental data. Utility Model Content

The two autoclaved concrete slabs and the insulation board are connected by a fixing structure, which includes multiple fixing bolts and nuts. Each fixing bolt passes through the two autoclaved concrete slabs and the insulation board. One of the autoclaved concrete slabs has a notch that matches the position of the fixing bolt. The nut is located in the notch. An iron plate is also installed between the end of the fixing bolt away from the nut and the other autoclaved concrete slab. A snap-fit ​​structure is also installed on the insulation board.

[0004] Preferably, the snap-fit ​​structure includes two snap-fit ​​blocks, which are fixedly installed on the insulation board by bolt assembly.

[0007] Preferably, the nut sidewall is fixedly connected to two fixing plates, and a fixing ring is fixedly connected between the two fixing plates.

[0008] Preferably, the side wall of the fixing plate is threaded with two fixing bolts.

[0012] Reference Figures 1-7 A novel composite insulation board that is easy to reinforce includes: The system comprises two autoclaved concrete (APC) slabs 1 and an insulation board body 2. The APC slabs 1 are porous concrete panels made primarily from fly ash, cement, and lime, cured under high-pressure steam. The panels require reinforced steel reinforcement. They can be used as wall materials or roof panels, making them a high-performance new building material. This panel is a new type of green building material with an oven-dry density of 600-700 kg / m³. 3 The cube has a compressive strength ≥4MPa and a single-point hanging force ≥1200N. It is lightweight and high-strength, suitable for non-load-bearing maintenance. Its thermal conductivity is 0.13W / (m·K) and its heat storage coefficient is 2.75W / (m·K). 2 •K), and has excellent thermal insulation; 100mm thick wall panels provide 40.8dB of sound insulation, 150mm thick panels provide 45.8dB, and 100mm thick wall panels have a fire resistance of 3.23 hours, far exceeding the first-class standard. It is durable, frost-resistant, waterproof, radiation-free, and allows for quick dry construction, eliminating the need for plastering and reducing costs by 20-25 yuan / ㎡. It also facilitates the mounting of air conditioners and other equipment, and is suitable for various climates and scenarios. This is existing technology and will not be elaborated further. The insulation board body 2 is located between two autoclaved concrete slabs 1, and the two autoclaved concrete slabs 1 and the insulation board 2 are connected by a fixing structure. The fixing structure includes multiple fixing bolts 5 and nuts 6. The fixing bolts 5 pass through the two autoclaved concrete slabs 1 and the insulation board 2, and one of the autoclaved concrete slabs 1 has a notch 3 that matches the position of the fixing bolt 5. The nut 6 is located in the notch 3. An iron plate 4 is also installed between the end of the fixing bolt 5 away from the nut 6 and the other autoclaved concrete slab 1. By tightening the nut 6, the two autoclaved concrete slabs 1 and the insulation board 2 can be fixed together. The iron plate 4 can make the fixing force even, thereby improving the fixing effect. The side wall of the nut 6 has anti-slip texture, which increases the friction, thus making it easier to... The tool is easy to clamp and tighten, and it is also convenient for the staff to tighten it. The side wall of the nut 6 is fixedly connected to two fixing plates 14, and a fixing ring 15 is fixedly connected between the two fixing plates 14. The fixing ring 15 is convenient for the staff to pick up, and the ring opening in the middle of the fixing ring 15 will not affect the normal use of the fixing bolt 1 5. The side wall of the fixing plate 14 is threadedly connected to the fixing bolt 2 16. After the nut 6 is tightened to the bottom, the fixing bolt 2 16 can be rotated to make one end of the fixing bolt 2 16 contact the recess 3. The friction between the fixing bolt 2 and the recess 3 makes the nut 6 have a self-locking force, which prevents the nut from rotating during long-term use and thus preventing it from loosening and falling off. This ensures the fixing effect of the nut 6. The insulation board 2 is also equipped with a snap-fit ​​structure.

[0013] The snap-fit ​​structure includes two snap-fit ​​blocks 7, which are fixedly installed on the insulation board 2 by bolt assemblies. Both snap-fit ​​blocks 7 have inclined sliding surfaces on their sidewalls. The autoclaved concrete slab 1 has two slots 8 on its sidewall, and each slot 8 has a stop block 9 fixedly connected to its sidewall. During installation, first align the two snap-fit ​​blocks 7 on the sidewall of the insulation board 2 with the two slots 8 on the sidewall of the autoclaved concrete slab 1. After alignment, insert the snap-fit ​​blocks 7 into the slots 8. After full insertion, slide the insulation board 2 to move the snap-fit ​​blocks 7 within the slots 8 to the stop block 9. Because the shape of the stop block 9 is designed to block the snap-fit ​​blocks 7, the insulation board 2 and the autoclaved concrete slab 1 are firmly fixed. Each slot 8 has a locking rod 10 fixedly connected to its inner side. Two baffles 11 are slidably installed on the wall. Compression springs 12 are fixedly connected between the two baffles 11 and the locking rod 10. The side wall of the locking block 7 has a slot 13. When the locking block 7 on the side wall of the insulation board 2 moves in the slot 8, the locking rod 10 can be inserted into the slot 13. During the insertion process, the two baffles 11 can slide inward through the side wall of 13. After the locking rod 10 has completely moved into the slot 13, the baffles 11 can slide outward by the elastic force of the compression springs 12 because the space inside the slot 13 is large. This causes the baffles 11 to unfold. The unfolded baffles 11 have a blocking effect, thus fixing the locking rod 10 in the slot 13 and making it impossible to pull it out. This, combined with the fixing structure, makes the fixing effect better.

[0014] In this invention, firstly, the worker aligns the two snap-fit ​​blocks 7 on the side wall of the insulation board 2 with the two slots 8 on the side wall of the autoclaved concrete slab 1. After alignment, the snap-fit ​​blocks 7 are inserted into the slots 8. After full insertion, the insulation board 2 is slid to move the snap-fit ​​blocks 7 within the slots 8 to the stop block 9. Because the shape of the stop block 9 is just right to block the snap-fit ​​blocks 7, the insulation board 2 and the autoclaved concrete slab 1 are firmly fixed. When the snap-fit ​​blocks 7 on the side wall of the insulation board 2 move within the slots 8, the locking rod 10 can be inserted into the slot 13. During the insertion process, the two baffles 11 can slide inward through the side wall of 13. After the locking rod 10 has fully moved into the slot 13, the space inside the slot 13... The baffle 11 is relatively large, so it can slide outward by the elastic force of the compression spring 12, thereby unfolding the baffle 11. The unfolded baffle 11 has a blocking effect, thus fixing the locking rod 10 in the slot 13 and preventing it from being pulled out. This, combined with the fixing structure, makes the fixing effect better. At this time, the two autoclaved concrete boards 1 and the insulation board 2 are aligned, and the two autoclaved concrete boards 1 and the insulation board 2 are connected in series by fixing bolt 1 5. The force is evenly distributed by the iron plate 4. Then, the nut 6 is threadedly connected to the fixing bolt 1 5. After tightening, the fixing bolt 2 16 is rotated so that the movement of the fixing bolt 2 16 abuts against the notch 3, thereby locking the nut 6 and preventing the nut 6 from loosening.
