隨著樓承板的迅速發(fā)展，其應(yīng)用越來越廣泛。常用的樓承板主要有65mm高的立邊和25mm低的立邊。近年來，越來越多的建筑采用樓承板。為什么在使用時經(jīng)常使用65毫米高的垂直邊緣？

With the rapid development of floor bearing plate, its application is more and more extensive. The commonly used floor bearing plate mainly has 65mm high vertical edge and 25mm low vertical edge. In recent years, more and more buildings use floor bearing plates. Why is a 65mm high vertical edge often used?

主要還是因為工程設(shè)計的需要，高立邊相比矮立邊具有更好的負(fù)載能力和抗風(fēng)性能，能更好的滿足屋面設(shè)計需要和規(guī)范標(biāo)準(zhǔn)。大家應(yīng)該知道，高立邊與矮立邊較大的不同在于支撐結(jié)構(gòu)。

Mainly because of the needs of engineering design, the high vertical edge has better load capacity and wind resistance than the low vertical edge, which can better meet the needs of roof design and specifications. You should know that the big difference between high vertical edge and low vertical edge lies in the supporting structure.

65mm高立邊樓承板采用直立鎖邊咬合系統(tǒng)，先讓鋁合金T支架與次檁條固定，再將樓承板板與T支架的梅花頭用鎖邊機咬合。另外在T支架下加裝隔熱墊，用螺絲予以固定，可以防止由于鋁構(gòu)件與鋼材之間產(chǎn)生電化學(xué)反應(yīng)，有效控制冷橋效用。

The 65mm high vertical side floor support plate adopts the vertical locking and biting system. First fix the aluminum alloy t support and the secondary purlin, and then bite the floor support plate and the plum blossom head of the t support with the locking machine. In addition, the thermal insulation pad is installed under the t-support and fixed with screws, which can prevent the electrochemical reaction between aluminum components and steel and effectively control the cold bridge effect.

高立邊這種采用專門的鎖邊機械將屋面板與T支架連接成為一個防水及抗風(fēng)的整體，在正負(fù)風(fēng)壓作用下能很好的承載對T支架的反復(fù)撕拉力和施工負(fù)載，還能有效避免因受力不均造成的板塊擠壓、拉伸變形，使得系統(tǒng)結(jié)構(gòu)非常安全穩(wěn)固。

The high vertical edge adopts a special edge locking machine to connect the roof panel with the t support into a waterproof and wind resistant whole. Under the action of positive and negative wind pressure, it can well carry the repeated tearing force and construction load on the t support, and can effectively avoid the plate extrusion and tensile deformation caused by uneven stress, making the system structure very safe and stable.

25mm矮立邊樓承板是采用立邊咬合結(jié)構(gòu)，咬合的方式與高立邊不同?；鶎优c檁條之間用自攻螺絲固定。基層與面板之間用不銹鋼或樓承板材料做的扣件固定，屋面板塊之間是以特有的咬合折疊方式連接，上下兩塊板搭載重合后，以270°單咬合或360°雙咬合，形成一個密封的整體，有一定的防水防滲性能。

25mm low vertical edge floor bearing plate adopts vertical edge bite structure, and the bite mode is different from that of high vertical edge. The base course and purlin shall be fixed with self tapping screws. The base course and the panel are fixed with fasteners made of stainless steel or floor bearing plate materials. The roof plates are connected in a unique bite folding way. After the upper and lower plates are loaded and overlapped, they form a sealed whole with a certain waterproof and impermeable performance by 270 ° single bite or 360 ° double bite.

正是由于兩者支撐結(jié)構(gòu)的不同，兩者的抗負(fù)載強度也就不同。所以金屬屋面工程中，特別是大跨度建筑屋面，多采用強度更高、更穩(wěn)固的高立邊屋面結(jié)構(gòu)。

Because of the different supporting structures, the load resistance of the two is also different. Therefore, in the metal roof engineering, especially the long-span building roof, the high vertical edge roof structure with higher strength and more stability is mostly used.
