The present invention uses an open joint type outer wall panel manufactured as a unit to finish the outer wall without caulking and to form the outer wall of the building, easy construction and save air and public affairs, and the open joint type outer wall panel In the open joint type exterior wall panel and the external wall construction method using the same, it is possible to secure excellent construction quality buildings with excellent effects such as insulation, order, moisture proof and sound insulation by using polyurethane foam of spray foam type. It is about.

As a method for constructing a curtain wall of a conventional steel structure building, a dry construction method using steel trusses is widely used. In the dry construction method using the steel truss, the vertical member (2) and the horizontal member (2a) is assembled in a lattice shape, transporting the steel truss made of a module having a predetermined standard to the site and installed on the slab of the building Then, the outside of the scaffolding or gondola to install the external finishing material (1) using an external material for fixing the external finishing material (anchor). 1 is a cross-sectional view showing a construction example of a dry construction method using a conventional steel truss, wherein the steel truss is a heat insulating material such as rock wool or glass wool on the surface facing the interior of the steel truss as shown in the drawing (4) And a back panel (3), such as a thin iron plate, which reduces the amount of condensation generated and enables the installation of the heat insulator (4) is formed, and the effect of heat insulation, moisture proof, order, kick and sound insulation in the building To bring. In addition, in the dry construction method using the conventional steel truss through the gap formed between the external finishing material (1) and the external finishing material (1) to prevent rain water or external air from entering, the external finishing material being constructed ( In order to prevent the external finish 1 from being separated or separated by integrating 1) and the external finish 1, the gap is closed with a filler of petroleum compound (caulking) 5 to finish. Therefore, in the existing dry construction method, the external finish material 1 serves not only as a surface finish but also functions as an exterior wall corresponding to an external climate. However, when the building is constructed by the existing dry construction method of caulking (5) in the gap (joint) as described above, the filler (caking, 5) is a kind of petroleum compound, such as ultraviolet rays, solar heat, acid rain, etc. Due to the external environment, the property becomes oily and flows down to the exterior wall of the building, and not only is unsightly in appearance, but also rainwater flows into the crevice due to the limited durability of the caulking (5). Problems such as leakage and condensation are caused to contaminate the corrosion of the steel truss and the interior finishing material supporting the external finishing material (1) has a problem of weakening the durability and stability of the building.

In addition, in order to solve such a problem, in recent years, the open joint method (external joint material), ie, the external joint material that excludes the caulking (5) in the gap (joint) formed between the external finish material (1) and the external finish material (1) The gap between the outer finishing materials (joints) should be constructed without caulking, so that the exterior finishing materials only play the role of finishing materials, and by creating a separate lining wall to block rainwater and outside air, the beautiful appearance at the time of construction is clean. Other techniques have been used to preserve them permanently. However, the open joint method as described above has a problem in that rainwater penetrates through an open gap (joint) to corrode the steel truss as a base structure. Between the curtain wall structure and the slab end, brackets for installing the curtain wall structure and a lot of bracing section steel are penetrated, and most end beams are close to each other so that the worker's hand can not easily enter. Therefore, due to such spatial characteristics, it is difficult to form a barrier wall that tightly blocks the flow of external air. In addition, in the existing dry construction method, as mentioned above, the caulking not only serves to block a gap between the external finishing material and the external finishing material, but also to block the flow of rainwater and external air, as well as the external finishing material and the external. By integrating the finishing materials with each other, even if a part of the external finishing material is separated or separated, it also serves as a structural material that binds the external finishing materials to be constructed with each other. However, since the use of such caulking is excluded in the open joint method, separation and detachment of the external finishing material occurs easily during construction, and in order to prevent such problems, a meticulous construction by a skilled worker must be made during construction. Therefore, careful construction is required during construction, which increases the construction process and cost.

In addition, in terms of insulation performance, there is a big problem in the construction quality of the insulation material such as rock wool or glass wool used in the existing dry construction method and open joint method. In general, the coefficients of thermal insulation and thermal permeability, the selection criteria for all currently insulated materials, are measured under the assumption and condition that there is no air flow on both sides of the insulation, but the actual conditions and environment of the installation site are quite different. First, as described above, the order wall of the open joint method is not tightly blocked, and the heat insulating material provided thereafter is mostly made of fibrous air through rock wool or glass wool. Of course, the back side is often made of tinfoil, but there are many obstacles due to various obstacles, and even if the seam is sealed with silver foil tape, the narrow space and the foil itself are easily torn even during the construction process. The function is hard to expect.

In addition, the existing dry construction method of attaching the external finishing materials to the steel truss one by one at the site where the steel structure is built is delayed the progress of other subsequent processes due to the increased workmanship and only delays the entire air. In addition, there is a problem that increases the cost of the public, it is difficult to ensure the safety of the worker to work. Therefore, in order to solve this problem, although the united building exterior wall panel is manufactured and constructed, the united building exterior wall panel is also made of a method using joint caulking, the above-mentioned problems are expressed as it is.

In addition, to solve the problems caused by joint caulking as described above, and attempted to manufacture a building exterior wall panel unitized by the open joint method, the joint joint method is excluded in the open joint method, the outer wall finishing material is manufactured integrally Since there is no structural element that can handle the weight of the united building exterior wall panel, it is impossible to manufacture the united building exterior wall panel by the existing open joint method.

The present invention devised to solve the above problems by using a joint-jointed outer wall panel manufactured by the factory as a unit without caulking construction to finish the building, it is easy to install, save air and public expenses, at the time of construction The purpose of the present invention is to provide an open joint type exterior wall panel that can maintain the beautiful appearance of a building and an exterior wall construction method using the same.
