楼承板在每个领域汇中的使用大家应该已经很清楚了，那么济南楼承板的延伸性能及工程铺设作用是怎样的呢？

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?

楼承板的延伸性能

Elongation property of floor bearing plate

楼承板本身有良好的延伸性，自重轻，自振周期长，较大变形下能吸收变形能，结构体系的连接多为柔性连接，围护结构可随主体结构发生变位，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.

自重减轻也会增强其抗震性能，自重减少一半，等同于降低抗震设防烈度一度，地震作用可降低30％—40％J，从而减少了很多有关抗震的构造要求，降低了工程造价。

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.

而楼承板建筑恰恰在这些方面能够满足要求，与其他建筑结构体系相比，楼承板建筑没有空气污染和噪音，也不会对森林等资源造成破坏，并且建筑材料可以回收再利用，减少了固体垃圾的出现，有利于人与自然的协调发展，代表着建筑行业的新水平。

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.

楼承板的工程铺设作用

Engineering laying function of floor bearing plate

楼承板是各向异性板，可以通过各向异性系数计算有效边长，根据有效边长的比来判断属于单向板还是双向板。

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.

如果是双向板，垂直肋方向配筋配在波峰上，顺肋方向配在波谷处，保护层要保证大于二十毫米，主要用来保持钢筋的粘结力。抗力则是通过垂直肋方向为肋以上混凝土厚度作为板厚，顺肋方向则从波谷算起，也就是说组合楼板的厚度就是板厚。

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.

在工程的铺设过程中，楼承板铺设连接钢梁，板端头与钢梁熔透点焊，中间采用栓钉与钢梁穿透熔焊。楼承板间用专用夹紧钳咬合压孔连接。

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.

堵头用专用镀锌堵头板与楼承板及钢梁点焊。如果楼面层结构高度变化不一致时，可以采用加焊型钢措施，让水平结构呈台阶过渡，当降低标高时工字梁腹板加焊角钢。抬升标高时工字梁翼缘加焊槽钢。

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.
