Description

Joiner assembly structure of free access floor for building

The present invention relates to a joiner assembly structure of a double bottom plate for a building, and more specifically, a joiner constituting the double bottom plate in an access floor used as a flooring material in high-end buildings, office buildings, and information buildings. (Joiner) improves the assembly structure to prevent the departure of the joiner, as well as breakage and detachment protection of the finishing material bonded on the double bottom plate and the double bottom plate for building to facilitate the separation and assembly of the installed double bottom plate. To a joiner assembly structure.

In general, high-end buildings, office buildings, information buildings, etc. use a double bottom plate to facilitate the wiring of communication cables and wires of various electronic products and home appliances and to freely change the position.

Such a double bottom plate is commonly referred to as a free access floor or an OA floor, and is often abbreviated as an access floor.

Since the double bottom plate is installed on the floor of the building of the concrete structure spaced apart by a predetermined height or more through the support, a wiring passage which is a space part is formed between the bottom surface and the double bottom plate at a predetermined interval. Through this, communication cables or wires of various electronic products and home appliances can be wired.

In addition, the double bottom plate not only forms the interior beautifully but also improves the cushion of the bottom surface, contributing to the improvement of the interior quality.

The double bottom plate is assembled on the support to support the load applied from the top, and the upper and lower plates formed of the upper plate of the metal material and the finishing material bonded to the upper surface of the upper plate, the edge (bond) of the upper and lower plates It is joined to the unit to reduce noise due to adjacent floor plate and friction, maintain the height between the finishing materials uniformly, to prevent damage and detachment of the finishing material and to install and remove the floor board smoothly, and is called a joiner of plastics It is composed.

However, in assembling a conventional double bottom plate, the bottom plate is bonded under the top plate to which the finishing material is bonded, and the joiner of the plastic material is simply press-fitted and fixed to the edge of the top plate to which the top plate is bound.

Therefore, the double bottom plate of such a structure has a disadvantage that the joiner inserted into the edge portion of the top plate is frequently caught by the pedestrian's feet or other objects, and is often pulled out. In order to prevent this, a bond must be applied during the manufacturing process of the bottom plate. Because the finishing material is easily soiled, there was an inconvenience of having to clean it frequently during the manufacturing process.

As another example, a plurality of holes may be drilled at equal intervals at the edges of the upper plate, and a plurality of bosses fitted into the holes may be integrally formed in the joiner of the plastic material to assemble each other, but in this case, the upper plate is manufactured. There is a problem in that the manufacturing cost is increased because a separate punching work is required to drill holes in the edge portion, and a plastic joiner must be obtained through injection molding rather than extrusion.

The present applicant (designer) has devised a design to solve the above problems and filed with the Korean Intellectual Property Office and registered as Utility Model Registration No. 155279.

However, the applicant's pre-registered Utility Model Registration No. 155279 forms a straight locking groove at the edge of the upper plate of the double thin plate and integrally forms a locking jaw at the joiner of the plastic material so as to fit in the locking groove. Although the joiner maintains a good engagement state by the locking groove and the locking jaw at the upper edge portion of the upper plate, there is a limit in maintaining a good binding state for a long time at the bottom of the edge portion.

Of course, joiner's self-elasticity keeps the binding state to some extent, but if the external impact is continuously applied for a long time such as when walking pedestrian or moving office furniture, the binding state may be relaxed.

In order to improve this, the applicant (designer) has filed with the Korean Intellectual Property Office and registered as Utility Model Registration No. 189510 and received the decision to maintain the registration.

The Utility Model Registration No. 189510 couples a joiner to a jaw formed at the bottom of an edge portion by curling the upper plate to a “⊂” type at the edge portion of the lower plate, or embossing the edge portion of the lower plate. By forming various types of jaws by joining, joiners were combined, which solved the problems of Utility Model Registration No. 155279, which was previously registered, to some extent, but the following problems occurred as a result of manufacturing and experimenting. It was.

In other words, in the case of the chin formed by embossing at the edge of the lower plate, the joined joiner was maintained in the assembled state without detachment at the beginning, but when it is used for transporting the package for construction or on the floor of the building, the joiner is used as a pedestrian. If the foot is frequently caught, the shape of the jaw is easily rounded off because it is made of rounds, and additional manufacturing is added to the manufacturing process, reducing workability and increasing costs.

In addition, when the upper plate is curled in the edge of the lower plate to form a jaw, the jaw is formed and the joiner is coupled to the lower plate, but the assembly state is maintained without detachment, but the height of the upper plate is due to the thickness of the upper plate. Since it is formed, the height of the jaw was limited to the thickness of the steel plate of the upper plate, and there was a limit of binding force.

Because of this, it is also easy to fall out if it is frequently caught on the foot of pedestrians when carrying or using the package.In addition, additional processes due to curling process are added during manufacturing, resulting in poor workability and increased cost. .

Therefore, the purpose of the present invention is the above-registered utility model registration No. 155279 (name; joiner assembly structure of double bottom plate) and Utility Model Registration No. 189510 (name; joiner assembly structure of building double bottom plate) Joiner assembly of the double bottom plate for building, which is designed to improve the efficiency, the joiner coupled to the edge of the double bottom plate increases the binding force at the bottom of the edge part, maintains a good binding state and improves workability during manufacturing. In providing a structure.

As a means for achieving the object of the present invention, the upper plate is bent at the edge portion of the double bottom plate to form a binding jaw by a predetermined height from the thickness of the lower plate, and the binding groove is integrated in the lower portion of the joiner coupled thereto. Formed to be configured to bind with the binding jaw formed on the bottom surface of the edge portion.
