Abstract
Description
The present invention relates to a composite beam, and more particularly to a composite multi-stage composite beam.
The synthetic bowls currently used in domestic and foreign countries are almost dependent on cold forming. This method is a method of producing a product by putting a coil wound around the main use material in a molding machine, which is widely used in order to minimize the loss of the material and to achieve rapid production.
However, this method uses a non-standard size material rather than a product of a standardized size, which leads to an increase in production cost and financial cost due to an increase in cost due to stock acquisition, excessive investment of the machine, and the like.
Also, most of the products have the exclusive production right for the above reasons, and the price of the product is relatively high due to the application of the profit without the competition.
In addition, there is a limitation in the production of the products from the conventional single molding machine, so that it is a reality that the delivery time is very difficult to observe when several sites simultaneously place an order, and it is a reality that the buyer sees the producer's opinion.
In addition, although the conventional cold-formed product is used by welding, a distortion of the plate during cold forming may occur, and it is difficult to produce various products when welding is used. In addition, there is a problem that it is difficult to meet the limitation on the width-to-thickness ratio of the compressive steel elements subjected to warping when the conventional welded composite beams are used for large beams.
It is an object of the present invention to provide a prefabricated multi-stage composite beam capable of variously modifying the cross-section and thickness of a composite beam.
