樓承板在電廠中起著重要的作用,樓承板差不多是受歡迎的建筑工程。不管建什么類型的建筑,樓承板都是不可替代的。我們知道這樣做的好處,所以我們選擇使用它。
Floor bearing plate plays an important role in power plant, and floor bearing plate is almost the most popular construction project. No matter what type of building is built, the floor bearing plate is irreplaceable. We know the benefits of this, so we choose to use it.
樓承板不僅用作建筑模型,而且還可以代替卷收器。如果它與混凝土板構(gòu)成復(fù)合材料的結(jié)構(gòu)部分,則該樓承板也稱為結(jié)構(gòu)樓承板(或復(fù)合樓承板)。
The floor support plate can not only be used as a building model, but also replace the retractor. If it forms a composite structural part with the concrete slab, the floor bearing slab is also called structural floor bearing slab (or composite floor bearing slab).
樓承板產(chǎn)品具有重量輕、強(qiáng)度高、承重大、抗震性好、施工快捷、安全環(huán)保,并可作為結(jié)構(gòu)強(qiáng)度的一部分而降低鋼筋用量、外觀整潔美觀等諸多優(yōu)點。正是由于其突出的技術(shù)經(jīng)濟(jì)性,不僅在電廠等工業(yè)建筑中被廣泛采用,而且在民用建筑中的應(yīng)用也迅速增多。
Floor bearing plate products have many advantages, such as light weight, high strength, large load-bearing, good seismic resistance, fast construction, safety and environmental protection, reducing the amount of reinforcement as a part of structural strength, neat and beautiful appearance and so on. Because of its outstanding technical economy, it is widely used not only in industrial buildings such as power plants, but also in civil buildings.
隨著樓承板在我國應(yīng)用實踐的增多,其應(yīng)用前景將更加廣闊。樓承板在國內(nèi)外電廠項目中的應(yīng)用現(xiàn)狀樓承板于20世紀(jì)50年代出現(xiàn)在美國等發(fā)達(dá)工業(yè)地區(qū) , 起初僅作為替代木模板使用。隨著對樓承板應(yīng)用和研究的不斷深入,結(jié)構(gòu)樓承板逐漸被應(yīng)用于工程實踐。
With the increasing application of floor bearing plate in China, its application prospect will be broader. Application status of floor support plate in power plant projects at home and abroad floor support plate appeared in developed industrial areas such as the United States in the 1950s. At first, it was only used as a substitute for wood formwork. With the deepening of the application and research of floor bearing plate, structural floor bearing plate is gradually applied to engineering practice.
在樓承板安裝時,當(dāng)樓板上有預(yù)留孔洞時,尺寸一般大于500毫米×500毫米 ,采用開孔措施,即在鋼梁上焊接型鋼龍骨,增加開孔剛度,開孔處斷開鋼筋網(wǎng)與型鋼焊接;開口尺寸小于500毫米×500毫米時,應(yīng)采取后開措施,即在樓板承重板上加堵頭隔板,連接鋼筋網(wǎng),待混凝土澆筑完畢后再切割鋼筋。
When the floor bearing plate is installed, when there are reserved holes on the floor, the size is generally greater than 500mm × 500mm, the first opening measure is adopted, that is, the section steel keel is welded on the steel beam to increase the opening stiffness, and the reinforcement mesh is disconnected at the opening and welded with the section steel; Opening size less than 500mm × After 500mm, the back opening measures shall be taken, that is, add a plug diaphragm on the floor bearing plate, connect the reinforcement mesh, and cut the reinforcement after the concrete pouring is completed.
當(dāng)樓面層結(jié)構(gòu)標(biāo)高變化不一致時,采取加焊型鋼措施,使水平結(jié)構(gòu)呈臺階過渡,當(dāng)降低標(biāo)高時工字梁腹板加焊角鋼;抬升標(biāo)高時工字梁翼緣加焊槽鋼。
When the elevation of the floor structure changes inconsistently, the measures of welding section steel shall be taken to make the horizontal structure transition in steps. When the elevation is reduced, angle steel shall be welded on the web of I-beam; When raising the elevation, the flange of I-beam shall be welded with channel steel.
