Description

Assembly type steel frame for curtain wall and its construction method

The present invention relates to a prefabricated curtain wall steel truss, which is conventionally joined by welding a vertical member and a horizontal member constituting the truss or forming a plurality of bolt holes in the vertical member and the horizontal member is a suitable method. It is related to the prefabricated curtain wall steel truss that is fastened by the clamping method of the vertical member and the horizontal member is fastened by the clamping method, the construction is easy to adjust the position, and the damage of the corroded member is reduced to enhance corrosion resistance and durability.

Conventionally, as shown in FIG. 1a, a vertical member is fixed to the building structure with anchors, and horizontal members connecting vertical members between the vertical members are welded to form curtain wall trusses. Galvanized ones were used. However, in this method, even though the vertical member and the horizontal member are welded at the factory and the rust film is coated with rust preventive paint, a lot of additional welding occurs during the connection work in the field, so that the rust prevented part is damaged and additionally, the rust preventive paint is additionally applied. The painted or damaged parts were left unattended, and even the galvanized members could not be prevented from being damaged by 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 room temperature, such as summer or winter, and the steel truss is corroded. It has accelerated the pace. Therefore, the conventional method cannot completely prevent corrosion, serious problems are expected such that the truss is corroded and the external finish material is dropped after a long time after installing the truss.

In addition, in order to improve the conventional method as shown in FIG. 1a, in the present inventors patent registration No. 227574, a reinforcing steel plate is welded to a horizontal member as shown in FIG. It was possible to assemble the horizontal member in the field, in which case it was difficult to achieve the purpose when the horizontal member has a closed cross section like an angular pipe. In other words, if the bolt joint reinforcement plate is installed at the end of each pipe and hot-dip galvanized, there is a risk that the air expands in the empty space of the pipe to separate the reinforcement plate, rupture the pipe, or explode or otherwise reinforce the plate. Even if holes were drilled in the respective pipes, the molten zinc solution flowed through the holes and hardened inside, so that the inner surface could not be galvanized. Therefore, the present inventor proposed the improvement as shown in Patent Application No. 10-1999-0020896, but in this case, the basic problem of FIG. 1b is solved, but the premise that the bolt hole for coupling with the horizontal member is formed in the vertical member. there was. However, when forming bolt holes in the vertical member and assembling the horizontal member, as in the case of FIGS. 1b and 1c, it is difficult to vertically adjust the height, and when the error of the height is severe, a separate height adjusting means must be used. There was this.

An object of the present invention is to connect the vertical and horizontal members by assembling work between the binding plate without forming a separate bolt hole for connecting the horizontal member to the vertical wall of the curtain wall, the connection position is free and easy to install the curtain wall steel trusses To provide.

Another object of the present invention is to combine the horizontal member to the curtain wall vertical member without welding and at the same time do not form a separate bolt hole for fixing the horizontal member in the vertical member to maintain a more perfect molten zinc plating state of the steel truss It is to provide a prefabricated curtain wall steel truss with improved corrosion resistance and durability of the truss.
