樓承板在每個領(lǐng)域匯中的使用大家應(yīng)該已經(jīng)很清楚了，那么
濟(jì)南樓承板的延伸性能及工程鋪設(shè)作用是怎樣的呢？
You should have a clear understanding of the use of floor bearing plates in each field. What is the extension performance and engineering laying role of Jinan floor bearing plates?
樓承板的延伸性能
Elongation property of floor bearing plate
樓承板本身有良好的延伸性，自重輕，自振周期長，較大變形下能吸收變形能，結(jié)構(gòu)體系的連接多為柔性連接，圍護(hù)結(jié)構(gòu)可隨主體結(jié)構(gòu)發(fā)生變位，其抗震性能得到了大大提高。
The floor bearing plate itself has good extensibility, light deadweight, long natural vibration period, and can absorb deformation energy under large deformation. The connection of structural system is mostly flexible connection. The envelope structure can be displaced with the main structure, and its seismic performance has been greatly improved.
自重減輕也會增強(qiáng)其抗震性能，自重減少一半，等同于降低抗震設(shè)防烈度一度，地震作用可降低30％—40％J，從而減少了很多有關(guān)抗震的構(gòu)造要求，降低了工程造價。
The reduction of self weight will also enhance its seismic performance. The reduction of self weight by half is equivalent to the reduction of seismic fortification intensity by one degree. The seismic action can be reduced by 30% - 40% J, thus reducing many structural requirements related to earthquake resistance and reducing the project cost.
而樓承板建筑恰恰在這些方面能夠滿足要求，與其他建筑結(jié)構(gòu)體系相比，樓承板建筑沒有空氣污染和噪音，也不會對森林等資源造成破壞，并且建筑材料可以回收再利用，減少了固體垃圾的出現(xiàn)，有利于人與自然的協(xié)調(diào)發(fā)展，代表著建筑行業(yè)的新水平。
And the floor bearing plate building can meet the requirements in these aspects. Compared with other building structural systems, the floor bearing plate building has no air pollution and noise, nor will it cause damage to forest and other resources. Moreover, the building materials can be recycled, reducing the emergence of solid waste, which is conducive to the coordinated development of man and nature, and represents a new level of the construction industry.
樓承板的工程鋪設(shè)作用
Engineering laying function of floor bearing plate
樓承板是各向異性板，可以通過各向異性系數(shù)計算有效邊長，根據(jù)有效邊長的比來判斷屬于單向板還是雙向板。
The floor bearing plate is an anisotropic plate. The effective side length can be calculated by the anisotropy coefficient, and the ratio of the effective side length can be used to judge whether it is a one-way plate or a two-way plate.
如果是雙向板，垂直肋方向配筋配在波峰上，順肋方向配在波谷處，保護(hù)層要保證大于二十毫米，主要用來保持鋼筋的粘結(jié)力。抗力則是通過垂直肋方向為肋以上混凝土厚度作為板厚，順肋方向則從波谷算起，也就是說組合樓板的厚度就是板厚。
If it is a two-way slab, the reinforcement in the vertical direction of the rib shall be placed on the wave crest, and the reinforcement along the rib direction shall be placed at the wave valley. The protective layer shall be greater than 20mm, mainly used to maintain the bond strength of the reinforcement. The resistance is the thickness of the concrete above the rib in the vertical direction of the rib as the plate thickness, and the thickness of the composite floor is calculated from the wave trough in the direction of the rib, that is, the thickness of the composite floor is the plate thickness.
在工程的鋪設(shè)過程中，樓承板鋪設(shè)連接鋼梁，板端頭與鋼梁熔透點焊，中間采用栓釘與鋼梁穿透熔焊。樓承板間用專用夾緊鉗咬合壓孔連接。
During the laying process of the project, the floor bearing plate is laid to connect the steel beam, the plate end is welded with the steel beam by penetration welding, and the middle is welded by stud and steel beam by penetration welding. The floor bearing plates shall be connected with pressure holes by special clamping pliers.
堵頭用專用鍍鋅堵頭板與樓承板及鋼梁點焊。如果樓面層結(jié)構(gòu)高度變化不一致時，可以采用加焊型鋼措施，讓水平結(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。
The special galvanized plug plate is used for spot welding with the floor support plate and steel beam. If the structural height of the floor changes inconsistently, the measures of welding section steel can be taken to make the horizontal structure transition into a step. When the elevation is lowered, the I-beam web is welded with angle steel. When lifting the elevation, the I-beam flange shall be welded with channel steel.
That's all for the above introduction of floor bearing plate. I hope it can help you. Thank you for your reading. If you need, please contact us http://m.jywhzx.com Contact.
