在上海(hai)市嘉(jia)定縣真如寺內。元延祐(you)七年(nian)(1320)建造,明清(qing)兩代屢加修葺(qi)。
真如寺大殿(dian)面(mian)闊、進深均為三(san)間(jian)(jian),屋頂為單檐(yan)歇山頂,平面(mian)呈正方形。進深十(shi)椽(chuan)(chuan),前四椽(chuan)(chuan)栿(fa)后(hou)乳栿(fa)用四柱(zhu)(zhu)(zhu)(zhu)。前槽空間(jian)(jian)頗為寬敞,并在四椽(chuan)(chuan)明(ming)栿(fa)上(shang)立蜀柱(zhu)(zhu)(zhu)(zhu),在蜀柱(zhu)(zhu)(zhu)(zhu)和前金(jin)(jin)(jin)柱(zhu)(zhu)(zhu)(zhu)間(jian)(jian)施(shi)平棊。平棊從次間(jian)(jian)轉向山面(mian),延至(zhi)后(hou)金(jin)(jin)(jin)柱(zhu)(zhu)(zhu)(zhu)止。前后(hou)金(jin)(jin)(jin)柱(zhu)(zhu)(zhu)(zhu)間(jian)(jian)施(shi)四椽(chuan)(chuan)栿(fa)及平梁,形成(cheng)大殿(dian)主(zhu)空間(jian)(jian)。其上(shang)置(zhi)重(zhong)椽(chuan)(chuan),遂(sui)有(you)草架(jia)之設,開(kai)明(ming)清兩代(dai)南方建(jian)筑中置(zhi)“軒”(見殿(dian)堂)的先(xian)例。殿(dian)內金(jin)(jin)(jin)柱(zhu)(zhu)(zhu)(zhu)均呈梭形,柱(zhu)(zhu)(zhu)(zhu)頂有(you)覆盆式卷殺(sha),形制優美。明(ming)間(jian)(jian)柱(zhu)(zhu)(zhu)(zhu)下置(zhi)石(shi)和素覆盆柱(zhu)(zhu)(zhu)(zhu)礎,次間(jian)(jian)柱(zhu)(zhu)(zhu)(zhu)下僅置(zhi)石(shi)。外(wai)檐(yan)柱(zhu)(zhu)(zhu)(zhu)有(you)明(ming)顯側腳,并有(you)生起,使檐(yan)口(kou)呈一緩和的曲(qu)線起翹(qiao)。大殿(dian)保(bao)留了(le)一些宋代(dai)建(jian)筑的特征。
斗栱為四(si)鋪作單(dan)昂,出耍頭(tou)。昂已是假昂,后尾另有挑斡,承托(tuo)下平。補間(jian)(jian)鋪作當心間(jian)(jian)置四(si)朵(duo),次(ci)間(jian)(jian)各用二朵(duo),都(dou)較宋(song)《營造(zao)法(fa)式(shi)》的(de)規定(ding)為多,具有從宋(song)向明清過(guo)渡(du)的(de)特點。梁(liang)栿采用矩形斷(duan)面的(de)月梁(liang),砍制工(gong)整,近于宋(song)式(shi)做法(fa),唯無(wu)琴面,同具有地(di)方做法(fa)特點的(de)武義延福寺(si)大殿也有顯著差別(bie)。
1963年(nian)進行落架重(zhong)修時(shi)于木構件(jian)榫卯隱蔽處發現記有構件(jian)名稱的墨字,經考證為初建(jian)時(shi)工匠所(suo)書寫,對研究中(zhong)國(guo)古(gu)代建(jian)筑史有參考價值。
