Description
本发明涉及气膜建筑技术领域，特别是涉及一种气膜建筑及其送风管道结构。
气膜建筑是用特殊的建筑膜材做外壳，通过风机向气膜内部充气，使气膜内外形成压力差而维持稳定的形状。气膜建筑以其低成本、快速、便于拆装、轻便等特点越来越多的运用于各行各业。
传统的气膜建筑，一般在地下建通风道，风机通过地下通风道充气到气膜内部。然而，有些场合不适合建地下通风道，一般采用外接风管来送风，这样一方面可以适应无法在地面下建造通风管的矛盾，另一方面建造成本会大大降低。但是由于气膜建筑具有柔性的特征，从开始充气到气膜建筑成型，气膜主体上的进风口与风机送风口的距离在不断变化，传统送风管在气膜建筑成型后风管长度会过长，产生自然弯曲，在外界因素(例如风)的作用下弯曲更大，甚至发生摆动，影响送风量和风压。
发明内容
基于此，有必要针对上述技术问题，提供一种可以避免送风管弯曲以避免影响送风量和风压的气膜建筑及其送风管道结构。
一种气膜建筑的送风管道结构，包括：
送风管，位于地面上方，所述送风管可伸缩，所述送风管的一端用于与风机相连通；
支架，用于支承所述送风管；及
卡环，所述卡环卡设于所述送风管的外周缘，且所述卡环固定于所述支架上，所述卡环的直径大于所述送风管的直径。
在其中一个实施例中，还包括软连接，所述软连接设置在气膜主体上，所述送风管通过所述软连接与所述气膜主体内部相连通。
在其中一个实施例中，所述软连接的一端焊接于所述气膜主体的外侧；和/或
所述软连接的另一端焊接于所述送风管上。
在其中一个实施例中，所述软连接的内表面设置有保温层；和/或
所述送风管外包有保温层。
在其中一个实施例中，所述送风管的长度大于所述气膜主体未吹起来时所述风机的出风口到所述软连接的中心之间的距离。
在其中一个实施例中，所述送风管的一端通过法兰或者卡箍设置于所述风机的出风口。
在其中一个实施例中，所述送风管与所述风机之间设置有密封垫。
在其中一个实施例中，所述支架上设置有弧形凹槽，所述送风管的外侧与所述弧形凹槽相配合。
一种气膜建筑，包括：
气膜主体，所述气膜主体上开设有进风口；及
如以上任意一项所述的送风管道结构，所述送风管道结构通过所述进风口与所述气膜主体内部相连通。
在其中一个实施例中，还包括风机，所述送风管的一端与所述风机相连通。
上述气膜建筑及其送风管道结构至少具有以下优点：
风机送出的空气通过可伸缩的送风管、再经过进风口后通入气膜主体内部，气膜主体内充气后维持稳定的形状，由于送风管位于地面上方，因此无需建地下通风道也能实现快速方便充气到气膜主体内部，有利于降低施工难度，也缩减了建造成本和工期。而且通过设置支架和卡环，将卡环卡设于送风管的外周缘，用于限制送风管的径向位移，但送风管可以沿轴向伸缩，因此可以有效避免送风管弯曲，从而避免影响送风量和风压。

请一并参阅图1、图2、图4及图5，为一实施方式中的气膜建筑10。该气膜建筑10可供博览会、展览会使用，也可以作为工业厂房、仓储车间、还可以作为羽毛球馆等等。具体地，该气膜建筑10包括风机100、气膜主体200、送风管道结构300、内通风管道结构400及外接风管结构500。
风机100用于向气膜主体200内充气。当然，在其它的实施方式中，气膜建筑10也可以不自带风机100，而通过外接的方式，此时风机100可不与气膜建筑10一起成套生产或/销售。
气膜主体200上开设有进风口210，风机送出的空气通过进风口210充入气膜主体200内。气膜主体200由特殊的建筑膜材制备而成，利用内外气压差来支撑整个气膜建筑10。需要撑开气膜主体200时，通过风机100不断的通入空气到气膜主体200内部。气膜主体200的内表面设置有保温层(图未示)，保温层由保温材料制成，可以提高气膜建筑10的保温性能。
送风管道结构300包括可伸缩的送风管310、支架320、卡环(图未示)及软连接330。可伸缩的送风管310位于地面上方，因此无需通过在地上挖建地下通风道。
请一并参阅图3，送风管310的材料是气密性的。送风管310的一端与风机100相连通。具体到本实施方式中，送风管310的一端通过法兰套设于风机100的出风口，通过法兰对接沿轴向固定送风管310。还可以在送风管310与风机100之间设置密封垫(图未示)，并在密封垫上车载法兰的对接处，并用压板压紧实现密封，以增加送风管310与风机100之间的密封性能。
当然，在其它的实施方式中，送风管的一端还可以通过卡箍设置于风机的出风口，卡箍是套在送风管的外面沿径向固定。对于卡箍套接，密封垫是在送风管内壁和与之结合的封口外壁的环状密封圈。
送风管310上设置有保温层311，保温层311由保温材料制成，可以提高送风管310的保温性能，防止通入热风时损失太多热量，或者防止通入冷风时吸收太多热量。
具体地，送风管310为圆筒形，因此各个方向的风压均匀，且圆筒形结构节省材料，抗压强度大。送风管310的长度要大于或者稍大于气膜主体200未吹起来时风机100的出风口到软连接330的中心之间的距离。将送风管310的长度设置的长一些是为了在气膜建筑10还没有吹起来的时候，送风管310长度能够达到气膜主体200的位置，吹起来的时候就压缩到正常使用的长度。
支架320用于支承送风管310。具体地，支架320可以用不锈钢方管或者角
钢做成与送风管310相匹配的结构。支架320上设置有弧形凹槽，送风管310的外侧与弧形凹槽相配合，形成送风管310与支架320相匹配的结构。风机100工作时，送风管310压缩，用支架320将送风管310支撑起来后，可避免可伸缩的送风管310弯曲，可避免送风管310弯曲后影响送风。
具体地，支架320的高度沿靠近气膜主体200的方向逐渐增高，以配合送风管310在通气时的状态，防止送风管310弯曲。
当要在室外使用且室外风较大的环境下，还可以在送风管310的外周缘卡设卡环，卡环再固定于支架320上。例如，卡环通过螺丝固定在支架320上。卡环的直径大于送风管310的直径。
软连接330的一端设置于气膜主体200上，软连接330与气膜主体200内部相连通。送风管310的另一端与软连接330相连通。例如，软连接330设置在气膜主体200开设有进风口210处，从送风管310进来的风量经过软连接330后通过进风口210进入气膜主体200内部。
具体地，软连接330的一端焊接于气膜主体200的外侧，软连接330的另一端焊接于送风管310上。气膜建筑10成型以后，气膜主体200是具备一定硬度的，在恶劣的天气情况下(例如大风或大雪天气)，气膜主体200会产生摆动或变形。而软连接330是可变形的，在气膜主体200摆动时，软连接330变形可以吸收这些位移从而减少摆动时在送风管310和气膜主体200连接处产生的局部应力，保护气膜主体200。软连接330的内表面也设置有保温层，保温层由保温材料制成，可以增加保温性能。
上述送风管道结构300至少具有以下优点：
风机100送出的空气通过可伸缩的送风管310、再经过软连接330、进风口210后通入气膜主体200内部，气膜主体200内充气后维持稳定的形状，由于送风管310位于地面上方，因此无需建地下通风道也能实现快速方便充气到气膜主体200内部，有利于降低施工难度，也缩减了建造成本和工期。而且通过设置支架320和卡环，将卡环卡设于送风管310的外周缘，用于限制送风管310的径向位移，但送风管310可以沿轴向伸缩，因此可以有效避免送风管310弯曲，从而避免影响送风量和风压。
内通风管道结构400包括管壁410，管壁410设置于气膜主体200的内侧。管壁410与气膜主体200共同形成一内通风道201，这时从软连接330经过进风口210进入的风量在内通风道201内。管壁410上远离底部的位置开设有出气孔411，内通风道201内的风量再经过出气孔411进入气膜主体200内部。
具体地，管壁410通过焊接的方式设置于气膜主体200的内侧，因此不仅可以增加管壁410与气膜主体200的牢固性，还可以增加管壁410与气膜主体200之间的密封性。
具体地，管壁410离底部3～4米处开始设出气孔411，因此出气孔411的位置开设的比气膜主体200活动的人员的身高都高得多，因此不会影响人员的活动。
出气孔411的数量为多个，多个出气孔411间隔排列于管壁410上。具体地，多个出气孔411均匀分布于管壁410上。因此，通过出气孔411进入气膜主体200内部的风量也比较均匀。出气孔的直径范围为2～5cm。
具体到本实施方式中，管壁410上还开设有接口412，接口412用于安装外接风管。
上述气内通风管道结构400至少具有以下优点：
风机100工作时，风机100送出的空气通过送风管道结构300吹到气膜主体200与管壁410共同形成的内通风管310道内，管壁410上远离底部的位置开设有出气孔411，因此风量通过出气孔411充入到气膜主体200内部，出气孔411的位置高度较高，因此可以避免影响底部人员的活动。而且出气孔411的设置成多个，多个出气孔411间隔设置，因此可以避免局部流速过高的问题。
外接风管结构500包括外接风管510、接头520、吊带530及平衡杆540。外接风管510的一端与管壁410上的接口412相连通。具体地，外接风管510的一端通过接头520与接口412相连通，接头520设置于管壁410上的接口412上。例如，接风管510的一端与接头520通过焊接的方式连接。外接风管510的周缘开设有风管气孔511。外接风管510的另一端可以是开口，也可以是封闭
的，或者在封闭的端部上再开设多个风管气孔511。
当然，在其它的实施方式中，还可以直接从气膜主体的外部拉进来一根独立的风管，连接在本实施方式中的外接风管上，由该独立的风管向外接风管内充入空气。
外接风管510悬吊于气膜主体200内。具体地，通过在外接风管510的周缘设置吊带530，气膜主体200内侧设置吊点220，吊带530的一端与外接风管510相连，吊带530的另一端与吊点220相连，因此外接风管510通过吊带530设置于气膜主体200内侧的吊点220上。
吊带530的数量为多个，多个吊带530平行间隔设置于外接风管510上，以分散每个吊带530所承受的重量。
请一并参阅图6，具体地，吊带530的一端通过与平衡杆540相连，平衡杆540再与外接风管510相连。例如，外接风管结构还包括滑块550及吊杆560，平衡杆540为中空结构，且平衡杆540的底部开设有导槽541。滑块550可沿平衡杆540的底部移动，吊杆560的一端设置于滑块550上，吊杆560的另一端设置于外接风管510上。具体地，滑块可以为滑轮或者滚轮。
具体地，外接风管结构500还包括吊环570、吊扣580及连接件590，吊杆560的另一端设置于吊环570上，吊扣580扣于吊环570上，吊扣580设置于连接件590上，连接件590直接设置于外接风管510上。因此，外接风管510可通过吊扣580方便扣在吊环570上。
上述外接风管510结构500至少具有以下优点：
风机100送出的空气从进风口210进入内通风管310道内后，一部分从从管壁410上的出气孔411进入气膜主体200内部，一部分通过管壁410上的接口412进入外接风管510内，再通过外接风管510周缘的风管气孔511，将风送到气膜主体200内部的其它区域，使充进的热风或者冷风均匀分布到气膜主体200内部的各个区域。
