Description

Prefabricated steel truss for curtain wall {Assembly type of steel frame for fitting curtain wall}

The present invention relates to a prefabricated steel truss for curtain wall. More specifically, when installing the steel trusses for the curtain wall in the curtain wall structure, the steel truss structure is achieved using only bolts and nuts without welding between the members, so that the construction is easy and the prefabricated steel trusses for the curtain wall do not cause corrosion between the members. It is about.

The steel truss of the conventional curtain wall, as shown in Figure 1a, to anchor the vertical member to the building structure and weld the horizontal member connecting the vertical member and the vertical member to form a curtain wall truss, rusty To prevent this, anti-corrosive coating or the galvanized member itself was used. However, in this method, even though the vertical member and the horizontal member are welded at the factory and the rustproof coating is applied to the rust, additional welding occurs in the connection work in the field, which causes damage to the rust-prevented portion and additionally prevents the rustproof coating from being applied. The painted or damaged parts were left unattended, and even galvanized members could not be prevented from damaging the plating process by welding, drilling or cutting. In this state, the curtain wall truss is located between the exterior wall finishing material and the building structure, and condensation occurs on the entire curtain wall truss during the season when there is a large difference between the outside temperature and the indoor temperature such as summer or winter. It will accelerate the speed of corrosion. Therefore, the conventional method cannot completely prevent corrosion, serious problems are expected such that the truss is corroded after a long time after the installation of the truss and the external finish is dropped.

In addition, in Patent Registration No. 227574 proposed by the present inventors to improve the conventional method as shown in FIG. 1A, as shown in FIG. 1B, a reinforcing plate is welded to a horizontal member and molten zinc plated to be integrally formed on the vertical member. The horizontal member can be assembled in the bolt hole in the field. In this case, when the horizontal member has a closed cross section like an angular pipe, it is difficult to achieve the purpose. In other words, if the bolt joint reinforcement plate is installed at the end of each pipe and hot-dip galvanized, air is expanded in the empty space of the angle pipe, so the reinforcement plate is separated or the pipe is ruptured or there is a risk of explosion. Even if a hole is drilled in each pipe, the molten zinc solution flows through the hole and hardens in the inside, so that the inner surface cannot be galvanized. The present inventor proposed a patent application No. 10-1999-0010896 as shown in Fig. 1c, but the basic problem of Fig. 1b is solved, but in this case, the horizontal member and the reinforcement plate are integrally welded and combined with the vertical member. As a result, the fundamental problem of damage to the rust-prevented parts due to the welding process has not been solved.

In order to solve the above problems, the prefabricated steel truss for curtain wall, which is designed to solve the above problems, is easy to construct by installing the curtain wall structure only by assembling bolts and nuts between the members without any welding process when installing the curtain wall steel truss in the curtain wall structure. And to provide a prefabricated steel truss for curtain wall with high construction efficiency.

In addition, the prefabricated steel trusses for the curtain wall of the present invention is protected from rust coating of each member, and the members are not rusted, and an object of the present invention is to provide a prefabricated steel truss for curtain walls with excellent durability.
