Description

Technical Field

[0001] This utility model relates to the field of concrete composite wall panel technology, specifically to a thermal insulation structure for autoclaved lightweight concrete composite wall panels. Background Technology

[0002] Autoclaved lightweight concrete (AFC) wall panels are a new type of wall building material with advantages such as lightweight, heat insulation, sound insulation, and fire resistance. They are manufactured by autoclaving cement, sand, and lightweight aggregates under high temperature and pressure after concrete pouring. AFC wall panels are suitable for various building types, including residential, commercial, and public buildings, and can be used as wall materials.

[0003] Utility model patent CN202689311U discloses an autoclaved aerated concrete (AAC) composite wall panel. The composite wall panel includes an upper fiber cement board, an AAC core layer, and a lower fiber cement board. The AAC core layer is covered by the lower fiber cement board, and the upper fiber cement board is covered by the AAC core layer. This utility model provides a low-cost AAC composite wall panel with good wall quality, possessing the advantages of AAC concrete (low price, lightweight, fire resistance, heat insulation, and sound insulation) as well as the advantages of composite panels (good flatness, convenient construction, and easy decoration).

[0004] In existing technologies, the thermal insulation performance of concrete composite wall panels is insufficient, resulting in a large temperature difference between the inside and outside of the panel, which affects the performance of the wall panel. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a thermal insulation structure for autoclaved lightweight concrete composite wall panels, which solves the problem of insufficient thermal insulation performance of wall panels.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermal insulation structure for an autoclaved lightweight concrete composite wall panel, comprising a concrete slab, with two symmetrically distributed thermal insulation outer panels slidably fitted inside the concrete slab. The concrete slab is an autoclaved lightweight concrete wall panel. Each thermal insulation outer panel includes a reinforcing layer, an elastic layer one, a thermal insulation layer, and an elastic layer two. The elastic layer one is disposed on the outer side of the reinforcing layer, the thermal insulation layer one is disposed on the outer side of the elastic layer one, and the elastic layer two is disposed on the outer side of the thermal insulation layer. A fixing seat is fixedly connected to the inner side of the thermal insulation outer panel. A hinge rod is hinged inside the fixing seat, and a connecting seat is hinged to the other end of the hinge rod. The connecting seat is slidably connected to the concrete slab. A fixing rod is slidably fitted inside the connecting seat, and the fixing rod is fixedly connected to the concrete slab. A spring is disposed on the outer side of the fixing rod. A guide rod is fixedly connected to the inner side of the thermal insulation outer panel, and the guide rod is slidably connected to the concrete slab.

[0007] Preferably, the reinforcing layer is made of diamond-coated wall panel material, and the thickness of the reinforcing layer is 20mm. By designing the reinforcing layer, the structural strength of the thermal insulation wall panel can be improved.

[0008] Preferably, the first elastic layer is made of sponge material, and the thickness of the first elastic layer is 15mm. By designing the first elastic layer, the impact resistance of the thermal insulation wall panel can be improved.

[0009] Preferably, the insulation layer is made of an integrated insulation board material, with the surface layer being a high-strength calcium silicate board, the reinforcing layer being a mixture of cement and polystyrene particles, and the core layer being a polystyrene insulation board. By designing the insulation layer, the insulation effect of the composite wall panel can be improved.

[0010] Preferably, the second elastic layer is made of UPVC foam board, and the thickness of the second elastic layer is 20mm. By designing the second elastic layer, the impact resistance of the thermal insulation wall panel can be further improved.

[0011] Preferably, one end of the spring is fixedly connected to the connecting seat, and the other end of the spring is fixedly connected to the concrete slab. The spring is designed so that its force can be applied to the connecting seat.

[0012] Preferably, the concrete slab has a guide groove inside, and a guide rod is slidably connected inside the guide groove. By designing the guide groove, the guide rod can slide inside the concrete slab.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the design of an insulation board, which is placed outside the wall panel to protect it. The outer surface of the insulation board is a reinforcing layer. The diamond wall panel has high hardness, high gloss, and is waterproof, fireproof, and corrosion-resistant. The elastic layers one and two act as a buffer to protect the concrete slab, improving the wall panel's impact resistance. Furthermore, the insulation layer provides excellent thermal insulation performance, enhancing the overall performance of the composite wall panel.

[0015] 2. This utility model designs a hinge between the fixed seat and the hinge rod. When the insulation board is impacted, the impact force will push the insulation board to slide into the concrete board. This allows the connecting seat to slide along the guide rod and compress the spring. Under the elastic action of the spring, the impact force can be buffered, reducing the impact of the impact force and improving the impact resistance of the composite wall panel, which can indirectly extend its service life.
