工程概況

由廣東省農(nóng)科院興建的中國(guó)農(nóng)村調(diào)研干部培訓(xùn)站工程裙樓四層結(jié)構(gòu)及四層天面結(jié)構(gòu)部分梁設(shè)計(jì)為勁性鋼梁。鋼梁設(shè)計(jì)主要采用工字型型鋼，鋼梁板材材質(zhì)為16Mn鋼，總工程量在27噸左右。裙樓天面結(jié)構(gòu)有勁性梁9條，梁的跨度分別為：11.31m、14.14m、17.12m和 26.8m四種，梁截面分別為：300×1000、300×1400；內(nèi)配200×800、200×1200 工字鋼。
此勁性梁工程施工特點(diǎn)難點(diǎn)是：梁的跨
Project Overview

Built by the Guangdong Academy of Agricultural Sciences research training of cadres in rural China podium four-station project structure and surface structure of part of the beam four-day design strength of steel beams. Designed mainly shaped steel beam steel, steel beams made of 16Mn steel plate, the total project amount of 27 tons. You Jin podium day surface structure of beam 9, the beam span, respectively: 11.31m, 14.14m, 17.12m and 26.8m of four, beam section, respectively: 300 × 1000,300 × 1400; inside with 200 × 800, 200 × 1200 I-beam.
The strength of beam construction features is difficult: the cross beam
