Description

Reinforcing material for insulating material under the door frame and insulation construction method for the lower part of the door frame using the same {Reinforcing material for insulating material under the door frame and insulation construction method under the door frame using the same}

The present invention relates to a reinforcing material for the insulating material under a door frame and a method of constructing insulation for the lower part of a door frame using the same. More specifically, the present invention relates to a reinforcement material for the lower insulating material of a door frame, and more specifically, to enable the side insulating material to be easily installed at the lower part of the door frame without damage, thereby effectively blocking the propagation of impact sound from the slab to the wall. This relates to a reinforcing material for insulation under a door frame and a method of constructing insulation under a door frame using the same.

In general, multi-unit housing such as apartments or multi-family houses is composed of a wall structure in which columns made of reinforced concrete with a certain thickness and slabs supported by walls are connected to form one structure. In other words, foundation work is completed by constructing slabs supported by pillars and walls according to the number of floors of the building, and then laying out pipes such as heating pipes and water supply pipes at regular intervals on the concrete slab, and then constructing cement mortar to a certain thickness. It is done.

Such architectural structures have a certain degree of blocking performance against airborne sounds caused by conversations or TV, but since the floor that divides each floor, that is, the slab, is constructed only with concrete, noise or shock generated inside the corresponding floor of the building is reduced. There was a problem in that the vibrations caused by this were easily transmitted to adjacent households and lower floors through the inter-floor slabs.

What causes these noise problems is mainly inter-floor noise, which corresponds to heavy impact noise caused by shock or vibration generated externally or internally. By failing to effectively block such inter-floor noise, the sound of children running and doors in apartment complexes can be heard. Closing sounds, pet dogs barking, the sound of washing machines, vacuum cleaners, and exercise equipment being used late or early, and the sounds of flushing water in the bathroom and kitchen are transmitted to neighboring households, causing considerable discomfort, and even causing discomfort to neighbors. By causing inter-generational civil complaints, government departments in charge are further strengthening these soundproofing standards, and various technologies are being proposed to prevent or reduce the generation of inter-floor noise.

In order to increase the noise blocking effect in such apartments, it is necessary to block impact sound between the floor and the side wall. If this blocking is insufficient, the impact sound due to the impact force propagates from the floor to the wall, causing damage due to the powerful and extensive transmission of the impact sound. Since this problem has been caused, a solution to this problem has become urgently needed.

As a conventional technology for reducing impact noise, Korean Patent Publication No. 10-2005-0048049, "Construction method of wall side insulation material for apartment complexes," has been proposed, which covers the area between the slab layer and the foamed concrete layer forming the interfloor floor of the apartment complex. In the construction method of an inter-floor noise prevention structure in which a floor buffer buried in is installed, the side insulation material attaching step of attaching the side insulation material along the lower surface of the wall; and the floor cushion installation step of installing the floor cushioning material on the upper surface of the slab layer; A foamed concrete layer pouring step to insulate the heating piping above the floor buffer; A plastered concrete layer forming step of forming a plastered concrete layer on top of the foamed concrete layer; And a side insulating material protruding above the plastered concrete layer. It consists of a cutting step of cutting.

However, in this prior art, when installing the side insulator to the lower part of the door frame, a hole has to be made in the side insulator to allow the passage of the hot water pipe installed in the lower part of the door frame. In the process of making this hole, the side insulator is torn around the hole. It was damaged, and the side insulating material was not properly installed in the designated position at the bottom of the door frame. Due to these issues, there was a problem in that the side insulating material was not performing its insulating function properly.

In order to solve the problems of the prior art as described above, the present invention installs a reinforcing material for the side insulating material at the bottom of the door frame, thereby reducing damage when drilling a hole in the side insulating material for the passage of a hot water pipe, and also reducing the damage caused by the side insulating material to the door frame.
