Description

[0001] The present invention relates to a prefabricated window and construction method,

The present invention relates to a prefabricated window and a method of constructing the same. More particularly, the present invention relates to a prefabricated window that can be detachably attached to a step of a building to form a window frame and a housing extension space, And a construction method.

Generally, in an apartment or a villa, an indoor space and a divided balcony or a veranda are formed.

Recently, the balcony or veranda has been expanded by remodeling to maximize the utilization of indoor space.

However, the expansion of the space through the remodeling is complicated not only because the construction is complicated, but also because the long construction time is consumed, the resident must migrate to another space for a limited time, and expensive construction costs are incurred.

In addition, since the building is vulnerable to thermal insulation due to expansion, the efficiency of indoor cooling and heating is lowered, and further, a separate storage space is removed, so that there is an inconvenience that articles such as an air conditioner outdoor unit or flowerpot must be stored indoors.

In recent years, in order to prevent a falling accident on a veranda or the like, a window is fixed on a window frame or a window that can be opened and closed is miniaturized.

Therefore, when a fire is generated in a room and the entrance is blocked, the remaining personnel may use a separate tool provided in the room, or a part of the body may be used to remove the glass of the window frame, It was necessary to escape from the position where the fire occurred.

However, the above method has a problem in that it is difficult for a woman or a senior citizen who is physically weak to use as well as a quick coping, and even if the glass is removed, there is a problem that it must wait in a fire occurrence space until it becomes a structure.

In addition, since the glass of the window frame has to be removed by using a separate tool provided in the room or a part of the body, it is difficult to remove the multi-layered glass having a thickness equal to or more than a certain thickness there was.

More specifically, one side of the load supporting portion 50 is provided on the outer wall of the building, and the other side is installed on the frame portion 10 exposed to the outdoor space of the building to support the frame portion 10. Accordingly, the load supporting portion 50 can stably support the load acting in the vertical direction on the frame portion 10, thereby preventing the frame portion 10 from sagging.

Next, the construction method of the present prefabricated window (1) includes a side surface (40a) and a front surface (40b) of a glass window (40) projected outside the frame portion (10) (Step S300). For example, the crusher 60 may include a plurality of striking portions 61 and a plurality of fixing means 62, 63 for fixing the plurality of striking portions 61 in a compressed state to the frame portion 10 have. The plurality of striking portions 61 include a first striking portion 61a accommodated inside the frame portion 10 and having an end opposed to the side surface 40a of the glass window 40 received in the frame portion 10, And a second striking part 61b which is accommodated inside the part 10 and whose end is opposed to the front surface 40b of the window 40 exposed to the expansion space 10a. The plurality of fastening means are disposed between the side surface 40a of the window pane 40 and the end of the first striking portion 61a to fix the first striking portion 61a in a compressed state, A first fixing means 62 separated from the first hitting portion 61b by the first hitting portion 61b so as to release the fixing of the first hitting portion 61a and a second fixing means 62 which is disposed between the front surface 40b of the window pane 40 and the end portion of the second hitting portion 61b The first hitting portion 61b is supported by the first fixing means 62 and is arranged in a compressed state inside the frame portion 10 while fixing the second hitting portion 61b in a compressed state, And a second fixing means 63 for releasing the fixing of the second hitting portion 61b by sliding in one direction crossing the sliding direction of the first fixing means 62. [ 5, when the first fastening means 62 is released, the first hitting portion 61a is moved in one direction by the elastic force to strike the side surface 40a of the window 40 The second fixing means 63 is released and the second striking portion 61b communicates with the front surface 40b of the glass window 40 and finally the second striking portion 61b is moved in one direction So as to strike the front surface 40b of the window 40. [

Next, in the construction method of the present prefab window (1), a window (40) for blocking the outdoor space of the building and the expansion space (10a) is installed at the site where the crusher (60) is installed (S400). For example, the glass window 40 may be formed in the form of a multi-layered glass having a thickness equal to or greater than a certain thickness, such as a double-layered glass or a double-layered glass.

Next, in the construction method of the present prefabricated window (1), a second opening / closing door (30) for selectively communicating the outdoor space of the building with the extension space (10a) is installed in the frame part (S500). For example, the second opening and closing door 30 is installed on the extension part 12 of the frame part 10, one side of which is exposed to the outdoor space of the building, and a guide rail (not shown) The outdoor space of the building and the extension space 10a can be selectively communicated with each other.

Next, a method of constructing the prefabricated window 1 is to install a first opening / closing door 20 for selectively communicating the interior space of the building with the expansion space 10a in the frame 10 (S600). For example, the first opening and closing door 20 is installed on the support portion 11 of the frame portion 10 and is slid along the guide rail 111 provided on the support portion 11 through the operation of the user, And the extension space 10a.
