Self-heating type anti-frost-cracking concrete building outer wall
The invention discloses a self-heating type anti-frost-cracking concrete building outer wall, and belongs to the technical field of building outer walls. The building outer wall can realize that on the basis of traditional anti-frost concrete, a gap is actively formed through a mode of autonomously sensing external cold energy, so that external air can enter the gap, a self-cracking heating pipe preset inside the gap is frozen and cracked in advance, heat dissipation powder in the pipe is released, a large amount of heat is released through the reaction characteristic of the heat dissipation powder and oxygen in air, the interior of concrete is heated through a self-contracting heat conduction pipe, meanwhile, half softening is achieved after solid is converted into liquid based on the phase change heat storage characteristic of a double-state filling body in the self-contracting heat conduction pipe, at the moment, an expansion bag on the other half extrudes the double-state filling body through the thermal expansion effect to force the double-state filling body to transmit extrusion force into the concrete, so as to compensate expansion of the concrete, the cracking phenomenon ofthe concrete is remarkably improved, and the strength of the building outer wall is improved.
本发明公开了一种自热式防冻裂混凝土建筑外墙,属于建筑外墙技术领域,本发明可以实现在传统抗冻混凝土的基础上,通过自主感知外界冷量的方式,主动形成缝隙使得外界空气可以进入,并通过内部预设的自裂发热管提前受冻破裂,释放出内部的散热粉末,利用其与空气中氧气的反应特点,释放出大量热量,利用自趋缩导热管向混凝土内部进行加热,同时基于自趋缩导热管内双态填充体的相变蓄热特点,由固体转变为液体后实现一半的软化,此时另一半上的膨胀包通过热膨胀作用对双态填充体实施挤压动作,迫使其将挤压力传递至混凝土内,用来补偿混凝土的膨胀,显著改善混凝土的开裂现象,提高建筑外墙的强度。
