Abstract

The present invention relates to a rail foundation block for a folding door. The invention is composed of a concrete block in which a pair of rails are embedded on the upper surface at a certain distance from each other on both sides relative to the center in the width direction, and a block body having interlocking connecting means at both ends. This allows for easy assembly and construction by excavating the floor of a building or parking lot where the folding door is to be installed for sliding movement and return of the folding door's transfer roller, and then connecting multiple block bodies as unit blocks in succession by interlocking their ends in the length direction through the interlocking connecting means. Through this, the workability of constructing the rail structure for sliding movement and return of the folding door's transfer roller on the floor of the building or parking lot is significantly improved, and the construction period for the rail structure can be significantly shortened.

Description

Rail foundation block for foldable entrance door The present invention relates to a rail foundation block for a folding door, and more specifically, to a concrete block that is pre-manufactured with a pair of rails embedded on its upper surface at a certain distance apart on both sides from the center in the width direction, and is composed of a block body having interlocking connecting means at both ends. This allows for easy assembly and construction by excavating the floor of a building or parking lot to be installed for the sliding movement and return of the folding door's transfer roller, and by connecting multiple block bodies as block units in succession by interlocking their ends in the length direction through the interlocking connecting means. Through this, the construction workability of the rail structure for the sliding movement and return of the folding door's transfer roller on the floor of the building or parking lot is significantly improved, and the construction period for the rail structure can be significantly shortened. Generally, in large facilities such as public facilities or factories, large doors are installed at the entrances to control access within the facility, and folding doors are installed and used to open and close the entrances by shortening or extending their length as needed. Figure 1 is a drawing showing a conventional folding door. A conventional folding door as seen in FIG. 1 is composed of a plurality of dome-shaped frames (2) in the shape of a ∩ that are arranged horizontally side by side at equal intervals and each has a pair of vertical bars, an extendable connecting frame (1) in the shape of an X that has each end connected between the vertical bars of adjacent dome-shaped frames (2) to allow the distance between the dome-shaped frames (2) to be extended, a transfer roller (3) provided at the bottom of the dome-shaped frames (2), and a rail (4) on which the transfer roller moves. In the conventional folding door configured as described above, when the door is opened, the expansion joint frame (1) and the dome-shaped frame (2) are folded manually or automatically and positioned inside the receiving section (5) installed on both sides of the open part of the door wall. As described above, the rails of the conventional folding door were installed as a pair on the floor of the entrance of a building or parking lot to open and close the entrance, and the transfer rollers of the folding door were installed to slide and return on the rails thus installed. For example, a rail for a folding door, which is installed to allow the transfer roller of the folding door to slide back, is typically fixed directly to the floor of the entrance of a building or parking lot, or fixed to the upper surface of a formed concrete structure after the concrete structure has been formed through on-site casting and curing. However, in the installation structure of a rail designed to allow the transfer roller of a conventional folding door to slide and return, as described above, there was a problem in that installation was not easy for the rail structure for folding doors. This was because, in the former case where the rail is directly fixed to the floor of a building or parking lot entrance, separate fixing means are required, such as fixing with concrete cement or providing fixing flanges on both sides of the rail and fixing by driving anchor bolts into the flanges. Furthermore, if the floor of the entrance to be installed is uneven, separate leveling work is required. On the other hand, in the installation structure of a rail for a folding door that allows the transfer roller of a conventional folding door to slide back, in the latter case where the rail is fixedly installed on the upper surface of a concrete structure formed on-site through excavation, pouring, and curing, on-site concrete pouring and curing are essential. Consequently, there was a problem in that the installation process required a long time, was complex, and significantly reduced workability. Therefore, there is a need for research and development regarding rail foundation blocks for folding doors, which are pre-fabricated as concrete block structures with a pair of rails extending and exposed above the floor of a building or parking lot to be installed for the sliding movement and return of the folding door's transfer rollers. These blocks can be easily assembled and installed in succession in multiple units after excavating the floor to be installed, thereby significantly improving the workability of the rail structure for the sliding movement and return of the folding door's transfer rollers and drastically shortening the construction period associated with the rail structure.
