Description

Temporary structure for elevator construction {TEMPORARY STRUCTURE FOR ELEVATOR CONSTRUCTION}

The present invention relates to a temporary structure for elevator construction.

Elevators are installed on each floor of a high-rise building so that people and cargo can easily move from the bottom to the top. Elevators are electrically operated using counterweights, cables and pulley devices. The elevator is installed in the elevator pit, and the elevator pit is installed in a space on one side of the building. The counterweight guide rail and the car side guide rail may be fixedly installed on the inner wall of the elevator pit or may be installed by a separate elevator structure.

Depending on the size of the building, a plurality of elevators may be installed in one building. In this case, the elevators may be installed individually, or a plurality of elevators may be installed adjacent to each other. In addition, even after the elevator is installed, replacement and repair/inspection work is frequently performed with a new elevator due to aging, breakdown, and inspection.

On the other hand, in order to perform the elevator-related construction as described above, the elevator construction is performed after installing a workbench or scaffolding inside the elevator pit. In general, elevator repair work of serious problems, including new installation/replacement of elevators, takes about 3-5 days and cannot be completed in a short period of time. If the test period is added, the construction period may be further increased.

In particular, in the case of a building in which a plurality of elevators are installed adjacently, other adjacent elevators are operated during replacement and repair of elevators. At this time, when an elevator in operation passes an elevator under replacement and repair work, the user may feel a sense of fear due to the generated noise. In addition, there is a problem that safety problems may occur when a falling object falls into a running elevator during replacement and repair of the elevator.

Therefore, when replacing and repairing elevators in a building in which a plurality of elevators are installed adjacently, noise generated along the elevator pits is transmitted to all floors, and there is a problem in that a number of related complaints are generated. Therefore, the elevator replacement and repair work should be carried out faster than the general construction work if possible, and the noise should be small.

The frame 110 may be formed of a steel beam and be connected and fixed in the width direction between the H beams H of the elevator pit P1. The frame 110 may be connected to the H-beam H by welding or screwing through a hole. A sound absorbing panel 120 and a sound insulating panel 130 to be described later may be connected to the frame 110 connected to the H beam (H). Specifically, the frame 110 may include a bent pipe 111 that is a vertically bent steel beam, and an A side 112 and a B side 113 that are two sides of the bent pipe.

Preferably, the fastening surface 121 is formed as a single-layer surface, and may include a plurality of holes. For example, the fastening surface 121 may be formed in the same or similar area to the A surface 112 or the B surface 113 of the bent pipe 111 .

For example, when the entire sound-absorbing panel 120 is formed in a multi-layer structure, it may be difficult to connect to the frame 110 using the fastening fixing part 140 to be described later because the thickness is thick, and the A side ( 112) and when the sound absorbing panel 120 is connected to the B side 113, respectively, may interfere. In addition, it is not easy to move and store the sound-absorbing panel 120 due to its thick thickness even during movement and storage.

The sound-absorbing surface 122 is formed in the center of the sound-absorbing panel 120 may serve to absorb the noise generated from the inside and outside during construction and work. The sound-absorbing surface 122 may be formed in a double layered structure in which the first surface 122-1 and the second surface 122-2 are disposed to face each other. That is, since the thickness of the sound-absorbing panel 120 that can absorb the noise is thickened, the air layer is formed and the noise passes, it is possible to absorb the noise more effectively than the sound-absorbing member formed as a member of the cross-section. Specifically, the sound-absorbing surface 122 is a plurality of hollow-forming pillars 122a disposed on the inside of the sound-absorbing surface 122, the hollow part 122b and the sound-absorbing surface 122 as an air layer formed inside the sound-absorbing surface 122. ) may include a plurality of protrusions formed on the outside of the convex portion (122c).
