【正文】 their bodies are fitter — but their brains are no more resilient than in the past. Some nations, notably Sweden, have already banned boxing on medical grounds. So far the British government has been reluctant to follow the Swedish lead and since 1981 five private members39。s opponents by delivering blows to their body and ultimately knocking them unconscious. It sanctions injury in the name of sport. That said, modern boxing appears almost genteel alongside its prizefighting predecessor in which bareknuckled pugilists fought to exhaustion, with fights often lasting several hours. A round ended only when one batant was floored。 ② 、建筑設(shè)計(jì)時(shí)應(yīng)盡量避免窗臺(tái)里低外高的結(jié)構(gòu)設(shè)計(jì)方案，特別是飄窗的外墻裝飾是面磚等粘貼材料，容易造成外窗臺(tái)比內(nèi)窗臺(tái)高。特別大風(fēng)過后，大部分推拉門窗在迎風(fēng)面的下檻都有不同程度滲水現(xiàn)象。 ② 、對(duì)于某些實(shí)際上已墻體化或大型化或處于高層建筑上層的門窗，宜參考幕墻設(shè)計(jì)規(guī)范執(zhí)行，并且應(yīng)在生產(chǎn)安裝之前通過抗風(fēng)壓的物理性能測(cè)試。 ② 、項(xiàng)目工程簡(jiǎn)單地按某一系列型材產(chǎn)品使用，既不參照門窗標(biāo)準(zhǔn)圖集選用，又無(wú)設(shè)計(jì)結(jié)構(gòu)力學(xué)計(jì)算。 2． 1安裝過程分為兩個(gè)步驟進(jìn)行交驗(yàn)，隱蔽工程、玻璃的安裝。 、用電布置安排，不任意亂拉、亂接，隨時(shí)清理安裝現(xiàn)場(chǎng)的廢料、垃圾等?？傊?，在生產(chǎn)加工上將作到三個(gè)保證：保證加工質(zhì)量，保證完成計(jì)劃任務(wù)，保證現(xiàn)場(chǎng)的安裝。 ：密封打膠 及清理工作階段 此階段為密封打膠及清理工作階段，在注膠接縫邊貼上不小于 25mm寬的保護(hù)膠帶，清洗膠縫，注膠時(shí)要均勻、飽滿，不得有注不到的地方，注好的膠面要進(jìn)行整修，保證膠縫表面光滑、平整，并將表面進(jìn)行清潔后撕去打膠用的保護(hù)膠帶。我公司保證在確定工期內(nèi)全部完成該項(xiàng)外裝飾工程 根據(jù)本工程量的實(shí)際情況，我們大致將整個(gè)工程分為四個(gè)施工階段。大面應(yīng)無(wú)劃痕、碰傷。 (措施將根據(jù)現(xiàn)場(chǎng)實(shí)際情況考慮 )。此過程控制要點(diǎn)如下： (二 )質(zhì)量保證措施 通過科學(xué)有效的管理，從方案設(shè)計(jì)到材料的購(gòu)買，從部件制作到購(gòu)件的組裝，乃至最后的現(xiàn)場(chǎng)安裝及現(xiàn)場(chǎng)質(zhì)量控制，均能得到可靠的保證，包括材料供應(yīng)商的質(zhì)量保證。 b．要求后補(bǔ)埋件安裝處理要符合規(guī)范，防腐措施要切實(shí)可靠。 2． 2項(xiàng)目經(jīng)理組織安裝隊(duì)對(duì)基準(zhǔn)軸線進(jìn)行復(fù)核，并填寫基準(zhǔn)復(fù)核記錄，如有偏差，請(qǐng)有關(guān)部門重新提供。 a．對(duì)特殊復(fù)雜形狀的工件只能以樣品檢查。 3 對(duì)角線長(zhǎng)度差 ≤ 2021 ≤ 對(duì)角線尺 ＞ 2021 ≤ 4 接縫高低差 ≤ 深度尺 接縫間隙 ≤ 塞片 5 框平面度 ≤ 檢查平臺(tái)、塞規(guī) 6 框料表面劃傷 深度小于鍍膜層 L≤ 1000 ≤ 4處 7 框料表面擦 每處面積 A≤ 300m2 8 接縫平直度 177。 (c)塑鋼窗框埋入墻面以下應(yīng)為 3— 5mm。 (c)洞口內(nèi)若有預(yù)埋鐵件，間距必須與窗框上設(shè)置的連接件配套。窗框上鐵腳間距一般為 450—500mm；設(shè)置在框轉(zhuǎn)角處的鐵腳位置，距離轉(zhuǎn)角邊緣 180200mm。 (d)組合窗框間立柱上下端應(yīng)各嵌入框頂和框底的墻體 (或梁 )內(nèi) 25mm以上。 拉線 9 組件平面度 檢查平臺(tái)、塞尺 施工安裝準(zhǔn)備 工程交底：由項(xiàng)目經(jīng)理、工程主管設(shè)計(jì)員根據(jù)施工組織設(shè)計(jì)、設(shè)計(jì)圖紙的內(nèi)容和要求對(duì)安裝隊(duì)進(jìn)行工程交底，明確工程的要求并按要求進(jìn)行施工安裝。設(shè)計(jì)部門在給出工件設(shè)計(jì)圖的同時(shí)，應(yīng)給出工件檢驗(yàn)樣品及樣品的極限樣品圖紙。 2． 3根據(jù)所提供的經(jīng)復(fù)核的基準(zhǔn)線，確定安裝位置線，安裝位置線須經(jīng)質(zhì)檢員、技術(shù)負(fù)責(zé)人、項(xiàng)目經(jīng)理三級(jí)檢驗(yàn)。 c．連接件安裝要可靠，安裝精度要在偏差范圍內(nèi)，切實(shí)做好防腐工作。 1． 1進(jìn)現(xiàn)場(chǎng)前的培訓(xùn)： a．由有關(guān)領(lǐng)導(dǎo)講解本工程的重要性，使安裝人員對(duì)此有足夠的認(rèn)識(shí)； b．由技術(shù)人員講解相關(guān)的標(biāo)準(zhǔn)規(guī)范和安全準(zhǔn)則； c．所有 技術(shù)向施工人員交底。 ：標(biāo)準(zhǔn)五金件、填充料及其它工程上的所使用的材料必須出具相應(yīng)的質(zhì)保書與有關(guān)的測(cè)試報(bào)告。 塑鋼門窗推拉門窗扇開關(guān)力應(yīng)小于 100N。 測(cè)量、放射線 、定位、洞口修補(bǔ) 該階段為前期準(zhǔn)備工作，其中包括測(cè)量、放線、定位、洞口修補(bǔ)。待整個(gè)工程安裝完畢后清理現(xiàn)場(chǎng)及臨時(shí)設(shè)施，交業(yè)主驗(yàn)收，同時(shí)準(zhǔn)備撤離現(xiàn)場(chǎng)。 9 ，我們將采用具有豐富安裝經(jīng)驗(yàn)的施工隊(duì)伍進(jìn)行安裝，并由具有該經(jīng)驗(yàn)的項(xiàng)目班子 來(lái)進(jìn)行管理，達(dá)到科學(xué)施工、有序施工，充分利用時(shí)間的每分每秒。 六、成品保護(hù)措施 施工現(xiàn)場(chǎng)產(chǎn)品防護(hù)措施 ，板材應(yīng)按安裝 的先后順序存放，避免造成安裝時(shí)來(lái)回倒放，造成人為損壞。 2． 2每個(gè)步驟施工過程 中，檢驗(yàn)員根據(jù)有關(guān)標(biāo)準(zhǔn)隨時(shí)進(jìn)行檢查，并做好記錄。造成門窗結(jié)構(gòu)強(qiáng)度和剛度未能達(dá)到門窗使用所在位置抗風(fēng)壓性能的指標(biāo)要求，門窗的受力桿件、五金 配件、密封件和粘接材料在風(fēng)荷載作用下產(chǎn)生嚴(yán)重的塑性變形，拉裂或損壞等，致使門窗產(chǎn)生雨水滲漏，產(chǎn)生的后果是往往是無(wú)法修復(fù)和彌補(bǔ)的。特別是中挺或者橫檔斷面尺寸可加大，壁厚增加，如型材計(jì)算強(qiáng)度和剛度與實(shí)際相距大的時(shí)候，型材內(nèi)可以襯墊加強(qiáng)鋼管或鋼板，來(lái)滿足實(shí)際需要的剛度和強(qiáng)度。 ② 、普通推拉門窗防水構(gòu)造達(dá)不到密閉要求，水密性能和氣密性能等級(jí)低。 （ 3） 、對(duì)策措施： 要求門窗專業(yè)承包廠家在門窗設(shè)計(jì)圖紙的基礎(chǔ)上，對(duì)門窗框各類拼樘料、中挺、橫檔轉(zhuǎn)角拼接料等細(xì)部防水節(jié)點(diǎn)，進(jìn)行專門的設(shè)計(jì)加工制作詳圖。 he then had half a minute39。 antiboxing Bills proposed in parliament have failed to reach the statute books. Most schools, both state and public, however, have dropped boxing from their physical education curriculum. Yet it should be noted that amateur boxing is exceptionally well regulated: not more than four rounds are fought, headguards are worn, and the referee is allowed to stop a fight to prevent serious injury. However, headguards, whilst absorbing energy from punches, present an even larger target to be hit and thus the number of blows striking home may well increase. Indeed, studies have shown that nonboxing sportsmen outperform even amateur fighters in neurological tests and, notwithstanding the safety precautions, three amateur fighters have suffered serious brain injury in British rings since 1988. For centuries boxing has been the epitome of overt masculinity, a demonstration of manliness and its embodying characteristics of courage, toleration of pain, and selfdiscipline. Women were merely ornaments displaying the round cards. This continues, but women have successfully demanded equal rights in the ring. In Britain, girls from the age of 10 are now allowed to spar in amateur boxing gyms, and recently professionalism, too, has been recognized for women — significantly later than its acceptance in the US where fights for women have appeared on the undercard of world championship events. The moral dilemma of boxing is that it provides an honest opportunity to escape poverty, but it also means for some a legal beating and for all the threat of permanent damage. Hitting below the belt is outlawed to protect the genitals, but surely the brain deserves even more protection, by reducing the concussive power of the boxing glove, developing safer headgear, excluding the head as a target — or by banning the sport altogether. The issue is not how hazardous boxing is but whether the hazards are acceptable. The term autism refers to
