The series of soft and composite floor board is centred on the yujitong brand, some new products, such as flexible anti-static floor board 、 inflaming retard-ing floor board 、 heating and heat ? conducting floor board, are produced . a thousand journey is walked, bon voyage 以宙際通牌軟、硬復(fù)合系列地板為中心,縱向推出軟抗靜電地板、夜明地板、阻燃地板、彩暖導(dǎo)熱地板等新產(chǎn)品,足行千里路,踏著他祝您一路平安。
The possible shear of the upper chord will change beam from flexural member to member under flexure and compression force . this is emphasised through design example . as a result , we find that composite floor system is good for reducing the height of floor system 在組合樓蓋體系設(shè)計(jì)中,筆者指出,可能的桁架弦桿剪力會(huì)使作為桁架弦桿側(cè)向支承的梁由彎曲構(gòu)件變?yōu)閴簭潣?gòu)件,這是在與桁架體系相適應(yīng)的樓蓋體系設(shè)計(jì)中應(yīng)該注意的一個(gè)環(huán)節(jié)。
Pk prestressed composite slab is a new composite floor structure by improving the traditional prestressed composite slab, its precast slab is a prestressed ribbed panel of which prestressed steel is a spiral ribbed high-strength wire, which make the precast component a higher stiffness and buckling capacity 本文研究的pk預(yù)應(yīng)力疊合樓板是通過不斷改進(jìn)傳統(tǒng)預(yù)應(yīng)力疊合板后研制的一種新型疊合樓板結(jié)構(gòu),其預(yù)制構(gòu)件為帶肋薄板,預(yù)應(yīng)力筋采用螺旋肋消除應(yīng)力高強(qiáng)鋼絲。
On the basis, three elastic calculation coefficients of the two-way composite slab on three common boundary conditions are deduced and calculated by applying the classic elastic plane theory . in the thesis, the elastic design methods of pk prestressed composite two-way slab is explored and studied by the example . furthermore, it is also studied how to apply the yield-line design method to design the prestressed two-way composite floor slabs 本文以此為依據(jù),應(yīng)用經(jīng)典彎曲薄板理論,采用李維法推導(dǎo)和計(jì)算了這種雙向樓板三種常見邊界下的撓度和內(nèi)彎矩彈性計(jì)算系數(shù),并在此基礎(chǔ)上通過算例探討了pk預(yù)應(yīng)力雙向疊合樓板的彈性設(shè)計(jì)方法,同時(shí)還對(duì)其塑性鉸線設(shè)計(jì)方法進(jìn)行了研究。
In this paper, based on a typical plan arrangement of two-user-on-one-storey and leap storey type multi-story house, the mechanical behaviours of the truss system, the difficulties in designing the truss system and the design of composite floor system is deeply analysed; the connection design, fire proofing and corrosion protection used in this structure system are briefly introduced 本論文以一梯兩戶躍層式多層住宅的一種典型平面布置為依托,以構(gòu)思該住宅結(jié)構(gòu)體系設(shè)計(jì)的方式,對(duì)這種桁架體系的受力性能、設(shè)計(jì)難點(diǎn)和應(yīng)用于該結(jié)構(gòu)體系的壓型鋼板?混凝土組合樓蓋的設(shè)計(jì)進(jìn)行了深入分析,對(duì)結(jié)構(gòu)采用的連接、墻體和防火防腐措施進(jìn)行了簡(jiǎn)單討論。
According to the new concrete code, the calculation formula are put forward concerning the load-carrying capacity during construction, the load-carrying capacity of cross-section bending, longitudinal shearing, the inclined-section shearing and part shearing during the application of the continuous composite floor slab, which provide the design proofs for the continuous composite floor slab 摘要根據(jù)新混凝土規(guī)范,給出了連續(xù)跨壓型鋼板與混凝土組合板施工階段的承載力計(jì)算公式及使用階段的正截面抗彎承載力、縱向水平抗剪承載力、斜截面抗剪承載力和局部抗沖切承載力計(jì)算公式,為連續(xù)組合樓板的設(shè)計(jì)提供了依據(jù)。
