Description
技术领域
本发明涉及耐火门制造技术领域。
背景技术
在各种灾害中，火灾是最经常、最普遍地威胁公众安全和社会发展的主要灾害之一。人类能够对火进行利用和控制，是文明进步的一个重要标志，但是人类使用火与同火灾作斗争的历史是相伴相生的，人们在用火的同时，不断总结火灾发生的规律，尽可能地减少火灾及其对人类造成的危害，在遇到火灾时人们需要安全、尽快的逃生。随着现代科技的发展，促进了高层建筑业的发展，火灾对人们物质财产和精神的危害越发严重。门板行业的技术人员也在试图通过对门板的改造来进行防火、耐火，常选用铁质等金属材料。但是金属门板由于材质的原因，导致质量极大，故而给我们的安装和搬运带来不便；并且，金属门板在火灾中容易产生高温，逃生者开启该门板困难，给逃生者带来诸多不便。
发明内容
本发明意在提供一种耐高温门板结构，以解决现有耐火门板质量大，容易产生高温的问题。
本方案中的耐高温门板结构，包括门扇和门框，所述门扇转动连接在门框上，所述门扇由外至内包括木质层和碳砖层，门扇的侧面设有弧形面，门框的内侧面设有和门扇侧面相贴合的弧形面；所述门扇设有中空的内腔，门扇的外侧设有和门扇内腔相通的上风口和下风口，所述门扇的空腔内壁连接有上支撑架和下支撑架，所述上支撑架上连接有抽风机，下支撑架上连接有排风机，所述碳砖层内壁上连接有温度传感器，所述温度传感器连接有用于控制抽风机和排风机的控制器。
有益效果：门扇由内而外包括木质层和碳砖层，且采用中空的结构，减轻了门扇的质量，便于安装，碳砖层具有较强的耐高温性能并且强度高，能够避免门扇在高温条件下变形，并且对门扇内部结构的支撑效果好；门扇和门框的贴合面为弧形能够增加贴合面的面积，增加门扇和门框的密封性，避免发生火灾时烟雾的飞入，同时还能起到隔音效果；门扇上开有上风口和抽风机相对，开有下风口和排风机对应，当火灾发生时，火焰加热门扇，当温度传感器检测到门扇的温度超过预警线，信号传递给控制器控制抽风机和排风机开启，使空腔内产生空气流动，空气从上风口进入，从下风口排出，从而带走门扇的热量，使门扇迅速的降温。
上述技术方案和现有技术相比，本发明的耐高温门板结构质量轻，容易搬运和安装，在火灾情况下，能够快速的使高温的门扇降温，防止门扇应温度过高而变形，同时也避免门扇由于高温使逃生者难以打开门扇逃生。
进一步，门框内安装有自动封口机构，包括转动连接在门框内的驱动杆，驱动杆为弯曲状并且两端分别为推动端和驱动端，其中驱动端安装有封口塞，驱动杆连接门框的部位安装有扭簧，驱动杆在扭簧的作用下致使推动端伸出门框弧形面。正常情况下当门扇开启时，扭簧致使驱动杆的推动端伸出门框的弧形面，当门扇关闭时，门扇的弧形面将门板推动端下压，致使驱动杆转动，驱动杆转动带动封口塞压紧在门缝上，进而达到封堵效果，防止声音从门缝传播。
进一步，所述碳砖层靠近抽风机和排风机的部位均设有弧形面，给空气提供光滑的路径，防止空气在风口逗留，影响空气的流动。
进一步，所述木质层的外表层涂刷有防火涂料，防止火焰烧坏木质层，使木质层被破坏。
进一步，所述碳砖层和木质层采用粘接剂粘接相连，木质层包括粘接相连的木质侧板和木质弧板，碳砖层包括粘接相连的碳砖侧板和碳砖弧板。制作门扇时，可以分别制作木质侧板、木质弧板、碳砖侧板和碳砖弧板，简化了加工工艺。
进一步，所述防火涂料包括：以质量份数计算，硼酸锌10份、重晶石10份、铝粉30份、氢氧化铝30份、石棉10份、碳酸铅50份、润滑剂80份、硅酸钠30份。此类涂料遇火不膨胀、不起泡，为不燃性涂料，完全由无机材料组成，涂料本身不燃烧和不发烟，受火时可形成釉状保护层以隔绝氧气，从而起到防火的作用。
附图说明
图1为本发明耐高温门板结构实施例的结构示意图；
图2为本发明门扇何门框配合的结构示意图。
具体实施方式
下面通过具体实施方式对本发明作进一步详细的说明：
说明书附图中的附图标记包括：木质层1、碳砖层2、上支撑架3、抽风机31、下支撑架4、排风机41、上风口5、下风口6、温度传感器7、门框8、驱动杆81、扭簧811、封口塞812。
实施例基本如附图1和图2所示：
一种耐高温门板结构，包括门扇和门框8，门扇通过转轴安装在门框8上，门扇由外至内包括木质层1和碳砖层2，门扇的侧面为弧形面，门框8的内侧面加工成和门扇侧面相贴合的弧形面，门扇的弧形面上安装有密封条。
门扇的内部为中空的内腔，门扇的外侧切割有和门扇内腔相通的上风口5和下风口6，门扇的内壁上端和下端均为光滑的弧形面，门扇由内而外包括木质层1和碳砖层2，且采用中空的结构，减轻了门扇的质量，便于安装，门扇和门框8的贴合面为弧形能够增加贴合面的面积，增加门扇和门框8的密封性，避免发生火灾时烟雾的飞入，同时还能起到隔音效果。门扇的空腔内壁焊接有上支撑架3和下支撑架4，上支撑架3上安装有抽风机31，下支撑架4上安装有排风机41，碳砖层2内壁上安装有温度传感器7，温度传感器7电连接于控制器，控制器电连接抽风机31和排风机41。门扇上开有上风口5和抽风机31相对，开有下风口6和排风机41对应，当火灾发生时，火焰加热门扇，当温度传感器7检测到门扇的温度超过预警线，信号传递给控制器控制抽风机31和排风机41开启，使空腔内产生空气流动，空气从上风口5进入，从下风口6排出，从而带走门扇的热量，使门扇迅速的降温。
门框8内安装有自动封口机构，包括转动连接在门框8内的驱动杆81，驱动杆81为弯曲状并且两端分别为推动端和驱动端，其中驱动端安装有封口塞812，驱动杆81连接门框8的部位安装有扭簧811，驱动杆81在扭簧811的作用下致使推动端伸出门框8弧形面。正常情况下当门扇开启时，扭簧811致使驱动杆81的推动端伸出门框8的弧形面，当门扇关闭时，门扇的弧形面将门板推动端下压，致使驱动杆81转动，驱动杆81转动带动封口塞812压紧在门缝上，进而达到封堵效果，防止声音从门缝传播。
门扇的木质层1外表层涂刷有防火涂料，该防火涂料由一下组分的原料制成：以质量份数计算，硼酸锌10份、重晶石10份、铝粉30份、氢氧化铝30份、石棉10份、碳酸铅50份、润滑剂80份、硅酸钠30份。此类涂料遇火不膨胀、不起泡，为不燃性涂料，完全由无机材料组成，涂料本身不燃烧和不发烟，受火时可形成釉状保护层以隔绝氧气，从而起到防火的作用。防止火焰烧坏木质层1，使木质层1被破坏。
碳砖层2和木质层1采用粘接剂粘接相连，木质层1包括粘接相连的木质侧板和木质弧板，碳砖层2包括粘接相连的碳砖侧板和碳砖弧板。制作门扇时，可以分别制作木质侧板、木质弧板、碳砖侧板和碳砖弧板，简化了加工工艺。
以上所述的仅是本发明的实施例，方案中公知的具体结构及特性等常识在此未作过多描述。应当指出，对于本领域的技术人员来说，在不脱离本发明结构的前提下，还可以作出若干变形和改进，这些也应该视为本发明的保护范围，这些都不会影响本发明实施的效果和专利的实用性。本申请要求的保护范围应当以其权利要求的内容为准，说明书中的具体实施方式等记载可以用于解释权利要求的内容。
