從物質(zhì)糧倉(cāng)到精神糧倉(cāng)

目前在中國(guó)的不少鄉(xiāng)村中存在著一種圓形的磚砌筒倉(cāng)，過去一直作為糧倉(cāng)使用。筒倉(cāng)的起源可以追溯到上個(gè)世紀(jì)的60年代，因?yàn)樘厥獾哪甏尘埃?dāng)時(shí)一場(chǎng)“深挖洞，廣積糧，備戰(zhàn)備荒”的運(yùn)動(dòng)正在全國(guó)開展。在這種情況下，國(guó)家亟需建設(shè)大量的糧倉(cāng)，但由于當(dāng)時(shí)缺少建設(shè)糧倉(cāng)的資金，也缺少建造高標(biāo)準(zhǔn)倉(cāng)庫(kù)的鋼材，因此就要求各個(gè)地方因地制宜，就地取材建設(shè)糧倉(cāng)以備用，鄉(xiāng)土筒倉(cāng)就是在這一時(shí)期應(yīng)運(yùn)而生。到了70年代中期，全國(guó)除臺(tái)灣以外的所有省市的鄉(xiāng)村都建有糧倉(cāng)，后來隨著時(shí)代的變化，到今天基本都被棄用了。

There is a kind of circular brick granaries in many villages in China, which have been used for grain storage in the past. The origin of granaries can be traced back to the 1960s. Due to the special historical background, a movement for " accumulating grain " was carried out across the country, because of lacking of funds and high-standard steel materials, a large number of granaries with local materials were built. By the mid-1970s, granaries were built in villages in all provinces and cities across the country, and with the changes of the times, which have been abandoned now.

在廣東省著名的僑鄉(xiāng)及世界文化遺產(chǎn)碉樓群所在地——江門的開平市塘口鎮(zhèn)，就留有一組五個(gè)這樣的筒倉(cāng)。先鋒書店選址在這五個(gè)筒倉(cāng)，也是看中了其歷史價(jià)值和其形態(tài)的特殊性。他們希望不僅能使廢棄多年的筒倉(cāng)被重新活化利用起來，而且能為先鋒的華南地區(qū)第一家鄉(xiāng)村書店創(chuàng)造一種特殊的書店空間品質(zhì)。

In Tangkou Town, Kaiping City, the famous hometown of overseas Chinese and the location of the World Cultural Heritage Diaolou Group in Guangdong Province, there is a group of five such granaries. The location selection of Librairie Avant-Garde in these five silos also emphasizes its historical value and unique form. They hope that not only can the abandoned granaries be revitalized and reused, but also create a special quality of bookstore space for the first rural Librairie Avant-Garde in South China region.

筒倉(cāng)目前的所在地靠近塘口鎮(zhèn)的邊緣地帶，但糧倉(cāng)前的廣場(chǎng)卻是鄉(xiāng)村市集（當(dāng)?shù)厝朔Q之為墟集）所在地，因此在某種程度上這里也是整個(gè)村鎮(zhèn)的活動(dòng)中心。而且其周邊本身也已經(jīng)有了不少鄉(xiāng)建的項(xiàng)目：青創(chuàng)基地、民宿、藝術(shù)家和建筑師的工作室等等。

The granaries are located close to the edge of Tangkou Town, and the square in front of the granaries is the location of the rural market. So to some extent, it is also the activity center of the entire village. Moreover, there are already many rural construction projects around it, such as youth entrepreneurship bases, homestays, studios for artists and architects, and so on.

01現(xiàn)狀

書店的改造用房一共七棟，除了一字排開的五個(gè)筒倉(cāng)之外，還有位于筒倉(cāng)以北后來加建的一幢三層宿舍樓，以及筒倉(cāng)南端的二層小辦公樓。筒倉(cāng)與筒倉(cāng)之間的也有不少加建，彼此之間并不完全獨(dú)立。

There are a total of seven renovation buildings for the bookstore. In addition to five granaries arranged in a straight line, there is also a three story dormitory building located at the north, as well as a two-story small office building at the south end of the granaries. There are also many additional constructions between granarie.

五個(gè)筒倉(cāng)均是磚混結(jié)構(gòu)，經(jīng)結(jié)構(gòu)檢測(cè)其質(zhì)量均為A級(jí)，都可以正常使用，但屋頂部分因?yàn)槟昃檬蓿胁煌潭鹊臐B漏，亟需修繕。而宿舍樓和二層小樓則存在各種安全隱患，現(xiàn)狀情況不夠理想。

The five granaries are all brick and concrete structures, and their quality has been tested to be Grade A, which can be used normally. And the roof part has varying degrees of leakage due to long-term disrepair. However, the current situation the dormitory building and two-story small building is unsafe.

作為糧倉(cāng)，筒倉(cāng)本身具有獨(dú)特且合理的空間構(gòu)造。原有糧倉(cāng)的室內(nèi)地坪比室外廣場(chǎng)高出了80公分，在當(dāng)年糧食存儲(chǔ)條件極為有限的情況下，在南方潮濕、多雨、高熱的氣候條件下，糧倉(cāng)達(dá)到了防洪、通風(fēng)、防蟲等的功能，體現(xiàn)了過去民間建造中的集體智慧。

As a granary, the silo itself has a unique and reasonable spatial structure. The indoor floor of the original granary was 80 centimeters higher than the outdoor square. In the past, in the humid, rainy, and hot climate conditions of the south, the granaries achieved functions such as flood prevention, ventilation, and insect prevention, reflecting the collective folk wisdom.

02修繕

五個(gè)筒倉(cāng)在進(jìn)行空間改造之前的第一步就是修繕，這其中主要是倉(cāng)頂修繕。過去這種磚圓倉(cāng)倉(cāng)頂?shù)慕ㄔ旆绞揭话阌兴姆N，分別是混凝土穹頂、混凝土攢尖頂、磚砌穹頂和木屋架攢尖頂。本項(xiàng)目用的是混凝土攢尖頂?shù)慕ㄔ旃に嚒?/p>

The first step before the renovation of the granaries is repairing, mainly the top of the silos. In the past, this kind of brick silo roof was generally constructed in four ways, namely, concrete dome, concrete tented roof, brick dome and wooden tented roof. These granaries use the construction technology of concrete tented roof.

倉(cāng)頂?shù)木唧w做法是：先把穹頂?shù)缺壤殖砂税辏缓笥么u在混凝土穹頂上砌出一道道磚“龍骨”，每一瓣里的磚“龍骨”都是平行的，使穹頂變成尖頂，這一步就確定了倉(cāng)頂?shù)男螤睢Ｈ缓笤儆没炷涟蜒鐾撸▽挕⑶市。┕潭ㄔ谝坏赖来u上，把俯瓦（窄、曲率大）蓋在仰瓦的縫上。最后再用混凝土把俯瓦包裹起來，倉(cāng)頂中心的尖尖留出孔洞來通風(fēng)。

這種做法在降水量大的地區(qū)能夠更快地排走倉(cāng)頂上的雨水，同時(shí)磚脊在倉(cāng)頂又形成了隔熱層，使倉(cāng)內(nèi)的溫度相對(duì)穩(wěn)定。可以說這是真正的低造價(jià)的綠色建筑。“米”字形的倉(cāng)頂分隔使得筒倉(cāng)無論是鳥瞰還是人視都具有很好的形象感受。這樣通過使用原有工藝對(duì)倉(cāng)頂?shù)男蘅樑c再造程，筒倉(cāng)的倉(cāng)頂滲漏問題得以解決，并基本保持了其原有的風(fēng)貌。

03改造策略

首先是五個(gè)筒倉(cāng)及其南北兩翼兩棟建筑的取舍問題。五個(gè)筒倉(cāng)肯定是要保留的，但兩端的宿舍和小辦公樓因?yàn)槟昃檬蓿Y(jié)構(gòu)安全性不高，且房屋的本體價(jià)值不佳，如保留會(huì)有較高的加固及改造費(fèi)用。因此設(shè)計(jì)中選擇將這兩處房屋拆除，結(jié)合功能在原址新建的策略。另外將連接筒倉(cāng)的各種搭建也都做拆除處理，這樣筒倉(cāng)就非常清晰地呈現(xiàn)出其在建設(shè)之初的原始樣貌。

The first issue is the demolishing choice of the two buildings on the north and south wings. The five granaries must be preserved, but the dormitory and small office buildings at both ends are under the low structural safety due to long-term disrepair, and the intrinsic value of the houses is not good. If preserved, there will be high reinforcement and renovation costs. Therefore, the design chose to demolish these two houses and combine their functions to build new ones on the original site. In addition, various structures connecting the granaries will also be dismantled, so that the granaries can present their original appearance very clearly.

其次，對(duì)于五個(gè)獨(dú)立的筒倉(cāng)而言，要滿足先鋒書店的使用功能有兩種連接方式。一種是串聯(lián)的方式，通過筒倉(cāng)的中心，用廊道連結(jié)起來。這種方式的流線最為便捷，但缺點(diǎn)是除了末端，每個(gè)筒倉(cāng)都會(huì)有兩個(gè)開口，而且交通在中間，書店的使用功能一定會(huì)受到不同程度的影響。還有一種則是在五個(gè)筒倉(cāng)的一側(cè)進(jìn)行連接，這樣的好處在于每個(gè)倉(cāng)體只需要在一側(cè)開口，筒倉(cāng)可以相對(duì)完整地保留，人的交通動(dòng)線在外圍，購(gòu)書和看書的行為不會(huì)受到太多的干擾。

Secondly, for the five independent granaries, there are two connection methods to meet the usage functions of the bookstore. One way is to connect by a corridor through the center of the granaries. which has the most convenient streamline, but the disadvantage is that apart from the end one, each granary has two openings, and the transportation will be in the middle, which will inevitably affect the functionality of the bookstore. Another method is to connect on one side of the five granaries. The advantage is that each granary only needs to be opened on one side, and the granaries can be relatively intact. So the reading will not be disturbed.

再者，筒倉(cāng)的東側(cè)面向廣場(chǎng)，如果在這一面進(jìn)行連接的化，雖然可以和廣場(chǎng)形成很好的互動(dòng)，但其立面相比原貌勢(shì)必會(huì)有較大的改變，而筒倉(cāng)東側(cè)一直以來都是廣場(chǎng)上各種活動(dòng)的背景，“天下糧倉(cāng)”幾個(gè)字也是鐫刻在這一側(cè)的倉(cāng)體之上，這形成了具有集體記憶的特殊場(chǎng)景。設(shè)計(jì)還是要保留下這種具有時(shí)間維度的場(chǎng)所氛圍，而把連接體設(shè)置在了西側(cè)，雖然這樣會(huì)犧牲一定的開放性和互動(dòng)性，但為村落保留了更加永恒的場(chǎng)所和記憶。

The east side of the granaries face the square. If connected on this side, although it can form a good interaction with the square, its facade will inevitably undergo significant changes compared to its original appearance. The east side of the granaries has always been the background of various activities on the square, and the words " Grand Granaries" are also engraved on this side of the silo, forming a special scene with collective memory. The design still needs to preserve this temporal atmosphere of the place, so the connecting corridor is set on the west side, although which sacrifices some openness and interactivity, it preserves a more eternal place and memory for the village.

在確定了書店主體連接方式的基礎(chǔ)上，兩端分別設(shè)置咖啡館和文學(xué)鐘樓。最后形成的總平面是七棟建筑并置地組合在一起，這看似奇怪，但卻又合情合理，也因此創(chuàng)造出非常獨(dú)特的書店空間，而這也正是筒倉(cāng)改造的魅力。

On the basis of main connection of the granaries, coffee shop is set up at the north end and literary bell towers at the south end. The final overall plan is a combination of seven buildings placed side by side, which may seem strange but reasonable, creating a very unique bookstore space, and this is also the charm of the granaries renovation.

04書店設(shè)計(jì)——空間裝置

在總圖設(shè)計(jì)中，我們沒有將主入口放置在朝向廣場(chǎng)一側(cè)，而是放在了背面的西側(cè)，原因和現(xiàn)狀有關(guān)。在1號(hào)倉(cāng)的這一側(cè)有一棵直徑1米多的大榕樹，它幾乎已經(jīng)和倉(cāng)體融為一體，這是一副自然與時(shí)間的畫面，設(shè)計(jì)想充分利用這一場(chǎng)景，從榕樹下進(jìn)入書店。廣場(chǎng)一側(cè)作為次入口使用，同時(shí)雙入口的設(shè)計(jì)也有利于通風(fēng)。主入口位于1號(hào)倉(cāng)，其兩側(cè)一邊是咖啡館，一邊是通過長(zhǎng)廊相連的各個(gè)筒倉(cāng)，整體布局簡(jiǎn)單明了。

In the overall design, we did not place the main entrance on the side facing the square, but on the west side, for reasons related to the current situation. On this side of Granary 1, there is a large banyan tree with a diameter of over 1 meter, which has almost merged with the granaries. This is a natural and temporal scene, and the design wants to fully emphasize this scene by entering the bookstore from under the banyan tree. The square side is used as a secondary entrance, and the design of dual entrances is also conducive to ventilation. The main entrance is located in Granary 1, with coffee shops on one side and various granaries connected by a long corridor on the other, making the overall layout simple and clear.

就筒倉(cāng)而言，每個(gè)的建筑面積約165平方米，倉(cāng)體內(nèi)部最低處6米，穹頂最高處8.4米左右。整個(gè)的體量和空間還是比較大的。面對(duì)這樣的高大空間，設(shè)計(jì)確立了兩段式的原則，下部是書架段，高度不超過2.4米，近人尺度，便于讀者取閱書籍，上部用我們?cè)O(shè)計(jì)的“空間裝置”來進(jìn)行填充。五個(gè)倉(cāng)的“空間裝置”各不相同，其功能除了解決下部書架段的采光之外，更多的具有精神屬性，它們同閱讀空間共同構(gòu)成每個(gè)倉(cāng)體不同的體驗(yàn)和感受。

As for the granaries, each has a construction area of approximately 165 square meters, with the lowest point inside the silo being 6 meters and the highest point on the dome being around 8.4 meters. Faced with such a tall space, we designed 2.4 meters bookshelf close to human scale, making it easy for readers to access books. The upper part is filled with "space installation". The spatial installations of the five granaries are different, and their functions not only lighting the lower bookshelf section, but also have more spiritual attributes. Together with the reading space, they form different space atmosphere for each granary.

1號(hào)倉(cāng)是詩(shī)歌倉(cāng)，并兼具書店的收銀區(qū)，同時(shí)也是主入口進(jìn)入后的公共門廳。詩(shī)歌是先鋒書店最看重的部分，因此往往將詩(shī)集設(shè)置在書店入口區(qū)域。在這里，我們沒有設(shè)計(jì)書架，而是做了一個(gè)半圓形的展臺(tái)來擺放詩(shī)集。展臺(tái)上空是用“十字形”結(jié)構(gòu)吊起的環(huán)形裝置，它壓低了展臺(tái)區(qū)域的高度，并照亮展臺(tái)。人們?cè)谌￠啎耐瑫r(shí)，還能感受到上部環(huán)形空間裝置所產(chǎn)生的向上的力量。

Granary 1 is for poetry collections, and also serves as the cashier area of the bookstore, as well as the public entrance hall after entering the main entrance. Poetry is the most important part of Librairie Avant-Garde, so poetry collections are often set up at the entrance area of the bookstore. Here, we did not design a bookshelf, instead, we designed a semi-circular exhibition stand to display books. Above the stand is a circular device suspended in a "cross shaped" structure, which lowers the height of the booth area and illuminates it. While reading books, people can also feel the upward force generated by the upper circular space installation.

不難看出，書籍在1號(hào)倉(cāng)中只占了很少一部分空間，其他部分都是在烘托和創(chuàng)造氛圍，這正是設(shè)計(jì)的初衷：書是主角，就像美術(shù)館可以為一件作品專門設(shè)一個(gè)展廳一樣，這里不用書籍做裝飾。

It is not difficult to see that books only occupy a small part of the space in Granary 1, while other parts are used to set off and create the atmosphere. This is precisely the original intention of the design: books are the protagonist, just like an art museum can set up a dedicated exhibition hall for a piece of work. In this bookstore, books are not used as decoration.

2號(hào)倉(cāng)是社科倉(cāng)。社科類圖書一直以來都是先鋒書店的優(yōu)勢(shì)品類，量也較大，所以在設(shè)計(jì)中我們整體沿筒倉(cāng)布置了一圈2.1米高的書架，有接近40米長(zhǎng)，書籍的量還是很可觀的。同時(shí)我們?cè)趥}(cāng)體中心設(shè)計(jì)了一個(gè)倒錐形的裝置，裝置中心是閱覽和休息區(qū)，上部和筒倉(cāng)6米高處相連，如同一朵盛開的牽牛花。書架區(qū)和閱覽區(qū)被巧妙分隔開來，巨大的曲面造型結(jié)合上面的一些孔洞處理，透過內(nèi)外光線的變化，形成很強(qiáng)烈的視覺效果，讀者在此宛如置身于一個(gè)巨大的空間雕塑之中。

Granary 2 is for social science collections. Social science books have always been the advantage category of Librairie Avant-Garde, with a large quantity. Therefore, in the design, we have arranged a circle of 2.1 meter high bookshelves along the granary, which is nearly 40 meters long. At the same time, we designed an inverted conical device in the center of the granary, with the reading and resting area at the center, and the upper part connected to the silo at a height of 6 meters, like a blooming morning glory. The bookshelf area and reading area are separated, with huge curved shapes combined with some hole treatments on top, creating a strong visual effect through the changes in internal and external light, making readers feel like in a huge spatial sculpture.

3號(hào)倉(cāng)是文學(xué)倉(cāng)。又因?yàn)槠湮挥谥虚g部位，該倉(cāng)也兼具多功能演講廳的功能，為此，倉(cāng)體中間設(shè)計(jì)了下沉式的坐席。根據(jù)文學(xué)倉(cāng)的圖書量，書架同2號(hào)倉(cāng)同樣布置，下沉式臺(tái)階坐席在平時(shí)可以作為休息閱覽使用。另外，圓形空間是很容易產(chǎn)生回聲的，作為演講廳一定要做聲學(xué)處理來避免。最后的措施是在倉(cāng)頂設(shè)計(jì)了七個(gè)圓形的反射吊頂，避免了倉(cāng)體內(nèi)部的聲聚焦。其特殊的形態(tài)本身就如同一個(gè)空間裝置，懸浮在筒倉(cāng)的上空。

Granary 3 is for literature. Because it is located in the middle, the granary also serves as a multifunctional lecture hall. Therefore, a sunken seat is designed in the middle of the space. According to the number of bookse, the bookshelves are arranged in the same way as in Granary 2, and the sunken step seats can be used for resting and reading in normal times. In addition, circular spaces are prone to echo, and as a speech hall, acoustic treatment must be done to avoid it. The final measure is to design seven circular reflective ceilings on the top of the granary to avoid internal sound focusing. Its special form itself is like a spatial installation, suspended above the silo.
