Doubravka瞭望塔

几年来，HAMR事务所一直在试验波尔结构，Doubravka瞭望塔就是这个实验过程的结果。可以毫不夸张地说，它是当前新兴建筑的一种技术和表现力。整个世界都在寻找一种与自然更好地和谐相处的方式，一种减少碳足迹的方式，最重要的是，一种摆脱我们现在正在经历的深层危机的方式，这座建筑就是我们对上述问题的回应。 

HAMR has been experimenting with bole constructions for a few years now. The tower Doubravka is the outcome of this experimental process. It could be said, without exaggeration, that it is a technological as well as an expressive impulse for currently emerging architecture. The entire world is looking for a way to live in better harmony with nature, a way to reduce the carbon footprint and above all, a way to emerge out of a deep crisis which we are now going through. This structure is our response to many of the mentioned questions. 

项目的设计及施工是由David Kubík代表HAMR监督的。在整个过程中，我们必须克服许多问题，其中包括当地的土地使用文件、建筑许可、整体的结构计算、整体的期限和木材的可用性。此外，还有一些挫折，如树皮的去除、单个树杆的弯曲限制以及对设计结构形状的影响。此外，还有连接处的结构计算，找到连接圆形木材的方法，将建筑固定在地面上，找到在地面上连接木材的有效方法，非典型的脚手架以及在四台起重机的帮助下在空中完成结构。最后，是天气的变化，由于场地无法进入，导致施工停顿了几个月之久。

The project as well as the construction was, on behalf of HAMR, supervised by David Kubík. During the entire process we had to overcome many problems. Among these was the local land use documentation, the building permit, structural calculations of the whole, the overall deadlines and the availability of acacia timber. Furthermore, there were setbacks such as the removal of the bark, limits in bending of the individual boles and the consequent impact on the shape of the designed structure. In addition, there were the structural calculations in the joints, finding a way to join the rounded timber, fastening the construction to ground, finding an effective way of joining the timber on the ground, atypical scaffolding and the completion of the structure in the air with the help of four cranes. Last but not least, it was the adversity of the weather, which caused a several month long pause in construction as the site was not accessible.  

然而，这些问题最终迎刃而解，承重测试也很成功，结果比我们预想的要好，布拉格70年来的第一座瞭望塔现在可以对公众开放了 

However, the problems have been solved, the load bearing tests have been successful with better results than we had hoped and the first lookout tower in 70 years in Prague is now accessible to the public! 

项目是由布拉格14区（市长Radek Vondra）指派的竞赛结果，并在LANDIA管理s.r.o.（Kamil Hošťák先生）的支持下完成，同时也得到了各个业主的资金支持。

The lookout tower is an outcome of a competition assigned by Prague 14 (mayor Radek Vondra) and has been completed with the support of LANDIA management s.r.o. (Mr Kamil Hošťák) as well as finantial support of the owners of the individual steps. Thank you all!

当布拉格14区的市长表示有兴趣建造一座木制瞭望塔时，我想我们可以做一个三条支架的，中间有一个悬空的楼梯。因为捷克没有竹子，所以我们决定用细竹竿建造。我们把它命名为 "Doubravka"。曾经有一段时间，小说《三叶草的日子》非常流行，可以说这是一株迟来的三叶草，从上个世纪出现在我们这个时代。 

When the mayor of Prague 14 expressed the interest in building a wooden lookout tower, I thought that we could do a three-legged one with a hanging staircase in the centre. And because there is no bamboo wood in the Czech republic, we decided to build out of thin boles. We named it Doubravka. There was a time when the novel „The day of the Triffids“ was very popular - one could say that this is a belated Triffid that has emerged from the previous century into our age.
