钢筋桁架板，诞生于2007年左右，据说是新进德国的工艺，当时耗资巨大，也想替代楼承板或者争夺楼承板市场吧。

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.

这种材料和楼承板的作用类似，也是用于楼面使用。不同的是，钢筋桁架板可以用在混凝土项目上，而楼承板用在混凝土项目上不多。

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.

钢筋桁架板是用钢筋和镀锌板两个焊接而成，其中，镀锌板选用0.4～0.5mm的镀锌板制成，相近于平板；而钢筋桁架由大量的钢筋通过焊接而成，主要起支撑受力作用。

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.

刚开始推广时，业内人不是特别敢用，因为是新产品，由于承担受力，大家还是比较小心，直到2010年设计规范出来，大家陆续的开始应用。

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.

钢筋桁架楼承板这个产品，不单单是对竞争性产品的敏感，同时也是对新产品新技术的关注。后来，发现了钢筋桁架板的优缺点及适用范围。

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.

关于适用范围，厂家在宣传上强调，不管钢结构还是混凝土结构都适用的说法。

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

首先，钢筋桁架由于钢筋用量大，所以它承受的无支撑跨距大，所以对于跨距在4.5米以上的建筑，选用钢筋桁架板比楼承板有利的，因为它可以做很大的无支撑跨距。楼承板的适合跨距是在3.6米以内，性价比较高，超过4.5米造价比钢筋桁架板贵，而且施工也麻烦（相对而言）。

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，由于钢筋比较多，可以承受很大的后期承载，所以对于后期承载力在1.5吨以上的建筑，钢筋桁架板更加合适（楼承板则还要大量配筋）。

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).

还有，在对于层数不高的工业厂房还是比较合适的。这个可以规避钢筋桁架板在高层建筑里大量占用吊车的弊端。

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.
