Description

Slab-connected partition wall of upper reinforcement structure {Slab-connected partition wall of upper reinforcement structure}

The present invention relates to a partition wall that divides and divides an indoor space so that it can be used separately, and more particularly, is composed of a partition wall connecting a ceiling slab and a floor slab to each other, wherein the partition wall is phased based on a ceiling finishing board. In addition to the separate construction of the upper and lower partition walls, the end of the ceiling finishing board is placed on the fastening means between the upper partition wall and the lower partition wall, so that the mutual binding state is increased through an organic coupling relationship between the upper and lower partition walls, as well as the upper and lower partitions It is about a slab-connected partition wall that blocks noise or dust between divided spaces due to the connection construction of the walls and at the same time performs insulation and crime prevention functions.

Recently, as industrial integration has been activated, centering on the knowledge industry and the information and communication industry, many small-scale factories have emerged. Knowledge industry centers (previously known as "apartment-type factories") have been "), many buildings are being built, and this knowledge industry center building is a multi-story collective building with three or more floors and is designed so that six or more factories can move in at the same time.

Looking at one floor of the knowledge industry center as above, it is designed in such a way that unit factories with the same size are arranged on both sides of the corridor. In some cases, two or more units are rented/sold, and if a tenant company leases/sells two or more unit factories, it is necessary to tear down the partition wall that divides the unit factories so that the entire unit can be used as a single space. , Generally, it was found that about 30% of the partition walls are dismantled when the rental/sale of a knowledge industry center is completed.

Looking at the conventional partition wall, it is fixedly installed, connected as one from the ceiling slab to the floor slab. First, the upper runner is fixedly installed on the ceiling slab, and the lower runner is fixedly installed on the floor slab to hold the location where the partition wall will be installed. , Support studs are erected at regular intervals between the upper runner and the lower runner, and two gypsum boards for the base material and gypsum board for the finish are installed on one side of the support stud. Subsequently, in order to enhance the soundproofing effect of the partition wall, a sound absorbing material such as glass wool is filled, and then, a gypsum board for a base material and two gypsum boards for a finishing material are installed on the other side of the support stud, respectively.

On the other hand, the ceiling slab is installed with a plurality of ceiling hanging poles of a certain length, and an upper support bar such as a carrying channel (C / C) is mounted at the lower end of the ceiling hanging pole. Bar) is fixed and installed orthogonally to the upper support bar to form a lattice structure such as a giant checkerboard. When the ceiling tex is screwed to the lower support bar and the ceiling tex is fixedly coupled to the gypsum board, a finishing material of the partition wall, through a frame molding, the fixed partition wall and ceiling construction is completed.

However, it is very difficult to dismantle the conventional fixed partition wall constructed as described above because the whole from the ceiling slab to the floor slab is integrally formed. In addition, as a critical path, the fixed partition wall is first installed before the ceiling and floor construction, and then the ceiling or floor structure is bonded and fixed to the partition wall. The usable ceiling structure was also damaged in the process of dismantling the fixed partition wall, so the ceiling construction had to be redone.

As such, due to the structural limitations of the conventional fixed partition wall, when the knowledge industry center requests to remove the partition wall, there is a problem in that it takes a lot of time and money to respond.

Accordingly, as in Patent Registration No. 10-1794718, which has recently entered, a number of installed so as to extend downward to the point where the ceiling tex coupled to the upper runner mounted on the ceiling slab and fixed by the ceiling sash suspended from the ceiling slab is located An upper partition wall including an upper stud and an upper finishing gypsum board coupled to both sides of the upper stud; A plurality of lower studs coupled to the lower runner mounted on the floor slab and installed to extend upward to the point where the ceiling texture fixed by the ceiling slab suspended from the ceiling slab is located, and a lower finishing material gypsum coupled to both sides of the lower studs lower partition walls containing boards; And a variable partition wall including upper and lower couplers in which the lower end of the upper partition wall and the upper end of the lower partition wall are fixedly coupled and the ceiling texture is fixed to both sides have been devised and registered.

In addition, in the case of Patent Registration No. 10-1794720, a plurality of upper studs coupled to the upper runner mounted on the ceiling slab and installed so as to extend downward to the point where the ceiling tex fixed by the ceiling slab suspended from the ceiling slab is located, An upper partition wall including an upper finishing gypsum board coupled to both sides of the upper stud; A plurality of lower studs coupled to the lower runner mounted on the floor slab and installed to extend upward to the point where the ceiling texture fixed by the ceiling slab suspended from the ceiling slab is located, and a lower finishing material gypsum coupled to both sides of the lower studs lower partition walls containing boards; an intermediate runner to which a lower end of the upper partition wall is fixedly coupled; And a variable partition wall including upper and lower couplers in which the lower end of the upper partition wall and the upper end of the lower partition wall are fixedly coupled and the ceiling texture is fixed to both sides have been devised and registered.

However, the partition wall as described above has an upper partition wall and a lower partition wall completely separated, so when an impact or physical load acts on the upper partition wall or the lower partition wall as the mutual bonding force is weakened, the interconnection part Or it has a problem that the boundary part is widened or displaced.

In addition, in the case of the upper partition wall, it is mounted on the front end of the lower partition wall, and at the same time, the ceiling finishing material is also mounted on both sides of the front end of the lower partition wall. Gaps or discrepancies occur, and as a result, noise or dust invades the other divided space, as well as having extremely unreasonable disadvantages in terms of insulation and shielding.

In addition, since the upper partition wall and the lower partition wall are not independently fastened, it is extremely uneconomical because it is impossible or very difficult to partially replace or repair the wall, and the gap between the partition wall and the existing ceiling finishing member is widened. There is a problem in that dust or foreign substances are continuously introduced into the room from the inside of the ceiling.
