鋼筋桁架板，誕生于2007年左右，據(jù)說(shuō)是新進(jìn)德國(guó)的工藝，當(dāng)時(shí)耗資巨大，也想替代樓承板或者爭(zhēng)奪樓承板市場(chǎng)吧。

Steel truss plate was born around 2007. It is said that it was a new technology in Germany. At that time, it cost a lot of money. I also wanted to replace the floor bearing plate or compete for the floor bearing plate market.

這種材料和樓承板的作用類似，也是用于樓面使用。不同的是，鋼筋桁架板可以用在混凝土項(xiàng)目上，而樓承板用在混凝土項(xiàng)目上不多。

This kind of material is similar to floor bearing plate, and is also used for floor. The difference is that the steel truss plate can be used in concrete projects, while the floor bearing plate is rarely used in concrete projects.

鋼筋桁架板是用鋼筋和鍍鋅板兩個(gè)焊接而成，其中，鍍鋅板選用0.4～0.5mm的鍍鋅板制成，相近于平板；而鋼筋桁架由大量的鋼筋通過(guò)焊接而成，主要起支撐受力作用。

The steel bar truss plate is welded by steel bar and galvanized plate. The galvanized plate is made of 0.4-0.5mm galvanized plate, which is similar to the flat plate; The steel truss is made of a large number of steel bars by welding, which mainly plays a supporting role.

剛開(kāi)始推廣時(shí)，業(yè)內(nèi)人不是特別敢用，因?yàn)槭切庐a(chǎn)品，由于承擔(dān)受力，大家還是比較小心，直到2010年設(shè)計(jì)規(guī)范出來(lái)，大家陸續(xù)的開(kāi)始應(yīng)用。

At the beginning of the promotion, people in the industry did not dare to use it, because it was a new product. Due to the bearing force, we were still more careful. Until 2010, the design specifications came out, and we began to apply them one after another.

鋼筋桁架樓承板這個(gè)產(chǎn)品，不單單是對(duì)競(jìng)爭(zhēng)性產(chǎn)品的敏感，同時(shí)也是對(duì)新產(chǎn)品新技術(shù)的關(guān)注。后來(lái)，發(fā)現(xiàn)了鋼筋桁架板的優(yōu)缺點(diǎn)及適用范圍。

This product is not only sensitive to competitive products, but also concerns about new products and new technologies. Later, we found the advantages and disadvantages of steel truss plate and the scope of application.

關(guān)于適用范圍，廠家在宣傳上強(qiáng)調(diào)，不管鋼結(jié)構(gòu)還是混凝土結(jié)構(gòu)都適用的說(shuō)法。

As for the scope of application, the manufacturer emphasizes that both steel structure and concrete structure are applicable.

首先，鋼筋桁架由于鋼筋用量大，所以它承受的無(wú)支撐跨距大，所以對(duì)于跨距在4.5米以上的建筑，選用鋼筋桁架板比樓承板有利的，因?yàn)樗梢宰龊艽蟮臒o(wú)支撐跨距。樓承板的適合跨距是在3.6米以內(nèi)，性價(jià)比較高，超過(guò)4.5米造價(jià)比鋼筋桁架板貴，而且施工也麻煩（相對(duì)而言）。

First of all, due to the large amount of reinforcement, the steel truss bears a large unsupported span. Therefore, for buildings with a span of more than 4.5 meters, the steel truss plate is better than the floor bearing plate, because it can do a large unsupported span. The suitable span of floor bearing plate is less than 3.6 meters, with high cost performance ratio. The cost of more than 4.5 meters is more expensive than steel truss plate, and the construction is also troublesome (relatively speaking).

再次，由于鋼筋比較多，可以承受很大的后期承載，所以對(duì)于后期承載力在1.5噸以上的建筑，鋼筋桁架板更加合適（樓承板則還要大量配筋）。

Thirdly, due to the large amount of reinforcement, it can bear a lot of late bearing capacity, so for buildings with a late bearing capacity of more than 1.5 tons, the steel truss plate is more suitable (the floor bearing plate needs a lot of reinforcement).

還有，在對(duì)于層數(shù)不高的工業(yè)廠房還是比較合適的。這個(gè)可以規(guī)避鋼筋桁架板在高層建筑里大量占用吊車的弊端。

In addition, it is more suitable for industrial plants with low floors. This can avoid the disadvantage of steel truss plate occupying a large number of cranes in high-rise buildings.
