Description

The present invention relates to a structure of an assembly fastener for an advertising curtain that can be quickly assembled and removed, and in particular, a first frame and a second frame are fitted to each other, and a guide space and a sandwiching space are formed to be fixed parts. The first frame and the second frame can be expanded and have a strong coupling ability by both ends of the provided compression portions pressing the side walls of the guide space, respectively, and quick assembly and removal are possible. It relates to the structure of the advertising screen assembly fastener.

Medium- and large-sized advertising curtains are not only overwhelming in size, but also have the effect of being eye-catching as a landmark even from a distance. Needless to say, they have advertising properties, especially in playgrounds, exhibition halls, buildings, and huge buildings. In addition to being the most preferred advertising medium for companies and foundations, it is also the focus of consumer attention when installed on the exterior wall. In other words, medium- and large-sized advertising curtains are outstanding in the current advertising media, and advertising companies are focusing on developing business opportunities. However, the conventional method of installing the advertising curtain (see FIG. 1) is to assemble a necessary advertising form skeleton mainly by a plurality of support posts A. Each of the columns A has a column groove (or column gap) B, and a retaining hole C2 provided on the edge of the advertising cloth curtain C corresponds to the column column ( Alternatively, the advertising cloth curtain C is pulled by being tied to the gaps B) of the columns with the clasps C1 and fixed to the entire column A in a flat state.

The problem often faced by the above-mentioned medium and large advertising curtains is that the advertising curtain C is connected to the grooves (or gaps between the pillars) B of the pillars A by the clasps C1, respectively. It must be stretched by pulling and fixing. This installation work not only takes time and effort, but in particular, the way to tie the clasp C1 is related to the problem of whether the cloth tie C and the clasp C1 have durability or will not loosen. However, when the advertising curtain C receives wind force from different directions, the air resistance received by the advertising curtain C as a whole is considerably increased, and the moment when the cloth C is vibrated or shaken. Due to the typical reaction stress, the retaining holes at the edges of the clasp C1 and the cloth basket C instantaneously receive high air resistance. The tension (stress) having an instantaneous high destructive force often tears the clasp C1 or breaks the retaining hole C2 at the edge of the cloth C. These problems cannot be solved only by how to fasten the clasp C1. However, it is unavoidable that work at a high place, which is necessary for later repairs, becomes unavoidable, resulting in a high risk and high cost.

In addition to the above, it becomes difficult for the advertising curtain C to withstand the breaking tension due to strong air resistance after use, and the air resistance received by the surface of the advertising cloth curtain C is directly transmitted to the entire column A. A dangerous situation may occur in which the instantaneous breaking tension causes serious damage such as distortion or deformation of the column A, or the entire steel structure of the medium- or large-sized advertising curtain is tilted.
