Description

THE NON-WELDING TYPE TRUSS FOR OUTER WALL PANEL}

The present invention relates to a welding-free exterior panel truss, and more specifically, to prevent the occurrence of fire due to the welding operation, and to reduce the operation time and cost by allowing the installation of the exterior panel to be performed in a relatively simple structure that does not require welding. It relates to a welding-free exterior panel truss that can be greatly reduced and has excellent rigidity in response to wind pressure.

In general, stone materials such as marble, granite, artificial stone, etc. are used to finish and decorate the exterior walls of buildings, and the prior art for installing stone exterior materials is known as Reference 1, for example.

Recently, a method of constructing various exterior panels in place of stone has been widely used for the purpose of decorating the exterior walls of buildings more beautifully and shortening the construction period, and various techniques for installing exterior panels have been developed. .

Among the various techniques for the installation of the exterior panel, the wet method is rarely used due to a long construction period and problems with workability, and so-called dry method using a bracket, bolt, nut, etc. is widely used. Let's look at this in detail.

Exterior panels, such as aluminum sheet panels, are mainly manufactured and processed in the form of square plates, and are attached to and constructed in buildings. In order to construct exterior panels, trusses are installed on the walls.

The truss is a metal frame made of a lattice-type unit module in which a vertical frame and a horizontal frame are installed on a slab or exterior wall of a building, and is constructed by fastening the exterior panels with bolts up, down, left, and right on the support frame installed on the outer surface of the wall.

Since the conventional truss is installed by welding the joint of the vertical member and the horizontal member, there are many concerns such as a fire occurring during the welding process.

Accordingly, a welding-free technology capable of construction without welding has been developed to prevent a fire and shorten the working time by developing a truss that does not require welding.

These are reviewed through references.

Reference 2; When constructing the interlayer slab or the exterior wall of the building with the wall surface as a plate structure such as stone, without welding at all, the exterior panel installed vertically and horizontally using only bolts, nuts and brackets Disclosed is an exterior panel construction device for an exterior wall of a building that can be fixedly installed.

In Reference 3; A plurality of brackets which are formed protrudingly fixed to the slabs installed between the floors of the building and have side sections in the form of elbows; A vertical beam in the form of a vertical square tube arranged between each of the brackets facing each other in a pair to be mounted by the bracket and allowing the wall surface to be mounted through a fixed angle; It describes the construction of the building curtain wall made of lamps.

In Reference 4; By installing the truss-like structure on the building wall only by assembling brackets and bolts without welding, it is possible to construct interior / exterior materials easily, while constructing a wave-shaped bracket to induce plastic deformation at the joints of the vertical and horizontal members. A constructionless welded truss structure has been disclosed for improvement.

In Reference 5; After fixing the wing beam using a wedge anchor on the wings projecting on both sides of the building's slab (wall), install an insulating material between the wing beams, and use the angle of each tube in the bolt fastening groove of the protruding member to designate the panel, color steel sheet, Disclosed is a non-welding wing beam truss for panel installation that finishes boards, gypsum boards, etc., without welding.

In Reference 6; In order to combine the horizontal and vertical profiles, there is no need for welding, there is no reduction in strength, and the height of the horizontal and vertical profiles is the same, so that panels can be bonded in various directions, and the occurrence of stenosis disasters can be fundamentally blocked during work. A bracket for a lower truss has been disclosed.

In Reference 7; After the vertical member is installed on the inner and outer walls of the building, the bracket is installed on the vertical member with a bolt, and the horizontal member is installed on the bracket with a piece, so it is not necessary to weld when installing the steel structure of the earthquake-proof panel. Disclosed is a method of constructing a construction-free, welding-free seismic truss unit bracket and a corner bracket, and a construction-free welding-free seismic panel construction method using the same.

Other references 8; A truss that can improve the shape of a horizontal coupling portion of a truss bar fastener installed at a crossing portion of a vertical truss bar and a horizontal truss bar, and by using a lattice-type fastener, a tightening force at a crossing portion of a vertical truss bar and a horizontal truss bar Bar fasteners are disclosed.

As described above, it can be seen that a method for allowing welding to be constructed out of a welding operation method having a high risk of fire due to splashing and welding without welding is known in the references discussed above.

However, these non-welding methods also have a number of problems, such as the work process is cumbersome and inconvenient due to the addition of the work process and the complexity of the structure due to the absence of the welding work, and this also takes a long time.

That is, since the welding method is not used for the operation of connecting the vertical frame and the horizontal frame, there is a problem in that manufacturing cost is increased due to the demand for a large number of components.

In particular, the exterior panel is installed in a large area compared to the thin thickness, which makes it vulnerable to strong wind and wind pressure. Wind pressure generated between the wall and the exterior panel [Inevitably, an empty space is inevitably formed between the wall and the exterior panel. It cannot be found in the prior art of the structure against the.

In other words, the wind pressure generated in the space between the wall and the exterior panel causes problems such as deformation of the exterior panel when the exterior panel is not securely fixed, but research and development to prepare for such wind pressure is very insufficient. Level.
